Overview

Two operations, one stroke. That is the whole machine.

A cartridge case starts life as a flat brass disc punched from strip, immediately pushed through a die and drawn into a shallow cup. Doing those two things in separate presses means handling the blank twice and losing the register between them. A double-acting press does both in one stroke — the outer slide holds and blanks while the inner slide draws — and that is why it sets the pace of the entire case line downstream.

Illustrative render — precision press tooling on a steel bench: polished carbide dies, hardened cutting and drawing punches of varying diameters standing upright, flat circular stripper rings and a heavy steel tool block with multiple precision bores

Fig · 02 Tool block, carbide dies, punches and stripper rings — illustrative render

Output comes from multiplying the stations, not from speeding up the stroke. The tool block carries eight or nine punch stations across a 148 mm strip, so every stroke yields eight or nine cups. At 150 strokes a minute that is around 72,000 cups an hour on the eight-fold block and 81,000 on the nine-fold — from a press cycling at a rate a person could count.

Everything else on the machine exists to keep that stroke fed and in register. A double de-coiler and straightener take the set out of the strip; a laser-monitored slack loop decouples the reel from the press; and a servo roller feed holding ±0.1 mm indexes the strip between strokes. Miss the pitch and you scrap the strip, the tooling, or both.

The press is not the hard part. Feeding it accurately, a hundred and fifty times a minute, for a whole shift — that is the hard part.

Engineered to Order

Designed against a purchaser’s specification

This press was engineered to an Indian ordnance manufacturing enterprise’s specification for 5.56 mm and 9 mm brass cups. No order followed, so no delivered machine and no operating reference is claimed — what exists is the engineering.

Multi-Fold · 8 or 9 Stations

Throughput from the tool block

Eight or nine punch stations across the strip, each with its own carbide die, cutting and cupping punch and stripper ring. Consumable tooling, tool-block trolleys for off-machine setting and a die storage cabinet are part of the scope, because changeover time is production time.

Interlocked · Annunciated

A press that tells you what is going wrong

Clutch and brake safety valve, central lubrication control with fault annunciation on the PLC screen, strip-feed, voltage-drop and air-pressure-drop monitoring, tool shielding, motor-temperature control and a flywheel dead-lock — on a machine storing this much rotational energy, the interlocks are the design.

Architecture

Coil to cup, in one line.

The schematic below is the whole line — de-coiling, straightening, loop control and servo feed into the press, the multi-fold tool block, and the separation of good cups, rejects and scrap on the way out.

Arc · 01

Coil Line & Feed

A double de-coiler with pneumatic pressure rollers carries one-tonne coils of 70/30 brass strip; a straightening unit removes the coil set; a slack loop watched by a laser sensor keeps reel inertia away from the press; and a computerised servo roller feed indexes the strip to ±0.1 mm, with a manual single-stroke mode for setting and trials.

Arc · 02

The Double-Acting Stroke

Cutting force of at least 630 kN and drawing force of at least 360 kN, with a 30 mm punch stroke and an 80 mm drawing stroke, at 120–150 strokes per minute. The frame is cast iron or stress-relieved fabricated steel to IS 2062, frame and crosshead drawn together by pre-pressed tie rods, on a cast or forged steel table — stiffness is what keeps punch and die concentric under load, so clearance stays even all the way round the cup.

Arc · 03

Tooling & Coolant

Eight- or nine-fold tool blocks with carbide dies, matched cutting and cupping punch sets and stripper rings, supplied with trolleys for off-machine setting. Tool temperature has to be held as tightly as force, so a dedicated pump, filtration and a chiller hold coolant between 15 and 25 °C — drift and the draw changes with it.

Arc · 04

Separation & Control

A nine-channel conveyor takes cups away and keeps each station’s output in its own channel while the press runs, so a sample check localises a failing punch to one station rather than to the batch; a cut-off shear collects scrap strip. An inbuilt PLC panel with pressure lubrication and fault annunciation runs the line, tropicalised for 440 V supply and 30–50 °C ambient.

Specifications

Reference configuration, tooled to your cup.

The parameters below describe a reference machine configured for 5.56 mm and 9 mm brass cups. Forces, stroke, tool-block fold, strip width and output are all set by the cup drawing, the material and the rate you need.

Illustrative render — a strip feed line: bright brass strip unwinding from a large coil on a powered de-coiler, passing through a straightening unit with banks of polished rollers, hanging in a controlled slack loop over a pit with a laser sensor aimed at it, then running through a servo roller feed into a guarded press infeed

Why the strip decides the cup

The press can only be as consistent as what it is fed. Strip thickness is held to ±0.02 mm and hardness to ±5 VPN, because both feed straight into the drawn wall — a harder or thicker strip draws differently and shows up as a cup out of tolerance rather than as a press fault.

That is also why the line is built around decoupling. The reel is heavy and its inertia cannot follow the press’s index rate, so the slack loop and its laser sensor sit between them, and the servo feed — not the reel — decides where the strip stops.

Variants

One forming principle, many cups.

Different tenders call this a blanking and cupping press, a cupping press, a double-acting deep-drawing press or a first-draw press. The engineering is the same; the tool block changes.

Var · 01

The Reference Configuration

The configuration on this page — 630 kN cutting, 360 kN drawing, 8- and 9-fold tooling on 148 mm strip for 5.56 mm and 9 mm brass cups at up to 81,000 an hour.

Var · 02

Other Calibres & Cup Sizes

Larger cups need more drawing force, deeper strokes and fewer stations across the strip; smaller cups allow a higher fold. Force, stroke, strip width and tool-block layout are re-scoped together against the cup drawing.

Var · 03

Commercial Deep Drawing

The same double-acting principle serves any high-volume drawn component — capacitor and battery cans, ferrules, closures and shells — in brass, aluminium or steel strip, with the tooling and coolant regime set by the material.

Var · 04

Line Elements & Retrofit

De-coilers, straighteners, loop control, servo feeds, cut-off shears, sorting conveyors and coolant/chiller sets can be supplied against an existing press — where the press is sound but the line around it caps the rate.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What does “double-acting” actually mean here?

Two slides working on the same stroke rather than one. The outer slide comes down first and clamps the strip through a blanking punch, cutting a disc and holding it flat against the die face; the inner slide then continues down through it and draws that disc into a cup. Because the blank is never released between the two operations it cannot shift, so the drawn cup stays concentric with the blanked circle. A single-acting press can combine the two, but only with a passive spring or die cushion holding the blank, so blank-holder force is whatever the cushion happens to give at that point in the stroke. Double action drives the holder positively, with its own force and timing through the stroke — which is why the alternative is usually blanking and cupping on separate machines, costing you both a handling step and the register between them.

Q · 02 How do you get 81,000 cups an hour from 150 strokes a minute?

By making several cups per stroke rather than by running the press faster. The tool block carries nine punch stations across the 148 mm strip, so one stroke produces nine cups: 150 strokes a minute × 9 × 60 gives about 81,000 an hour. An eight-fold block gives about 72,000. Multiplying the stations rather than the stroke rate keeps press dynamics, tool life and lubrication within sensible limits — a press trying to reach the same output on one station would have to cycle at over 1,300 strokes a minute, which no crank press of this force will do.

Q · 03 Why does the coolant need a chiller?

Because deep drawing is a thermal process as much as a mechanical one. Nine draws per stroke at 150 strokes a minute puts a lot of work into the tooling, and as coolant temperature rises its viscosity and film strength fall, which changes friction at the die radius, and with it how much the wall thins as the blank is drawn in. Wall thickness itself is set by punch-to-die clearance; friction decides how evenly the metal flows into it. Left uncontrolled, cup dimensions drift through a shift and the tooling wears faster. Holding the coolant between 15 and 25 °C with a dedicated chiller and filtration keeps the draw the same at the end of a run as at the start.

Q · 04 Why separate rejected cups by station?

Because with eight or nine stations working at once, a fault is usually one station rather than the machine. If good and rejected cups from every station go into a common bin you know only that the batch has a problem; if the conveyor keeps each station’s cups in their own channel while the press runs, a sample check points straight at the punch, die or stripper that is going. That turns an unplanned line stop and a sorting job into a single tool change at the next changeover.

Q · 05 Has this press been built?

Not yet, and it is worth saying so plainly. The design on this page was engineered to an Indian ordnance manufacturing enterprise’s specification for 5.56 mm and 9 mm brass cups and passed technical evaluation against it, but no order followed — so we claim no delivered machine and no operating reference. A technical evaluation is not an approval or certification. What exists is the engineering: press sizing and frame design, tool-block architecture, coil line and feed, coolant and control scope. We would build it to your cup drawing on the same basis.

Q · 06 Can you tool it for our cup?

Yes — the cup drawing is the starting point for everything else. Send the cup geometry and tolerances, the strip material, thickness and hardness you can source, the output you need and the floor space and services you have. Blanking and drawing force, punch and draw stroke, tool-block fold, strip width, feed rate, coolant duty and conveyor layout are then sized against that, and the acceptance regime — geometric accuracy and output sampling — agreed at design review. A compliance matrix returns within two working days.
