A: The double-chain drawing machine is a plastic processing method that deforms the metal blank through the die hole of the drawing die. During the drawing process, the billet produces plastic deformation in the drawing die, and after passing through the drawing die, the cross-sectional shape and size of the billet are the same as the exit of the drawing die hole. Therefore, by changing the shape and size of the hole in the drawing die, the corresponding drawn product can be obtained.

C: equipment composition

This equipment consists of 1 set of automatic feeding rack, 1 set of automatic head extrusion machine, 1 set of drawing main machine, 1 set of receiving rack, related electric control system and hydraulic system, etc.

C－1 automatic loading rack

Place the blank on the unloading table of the automatic loading rack. Dial the material by the material cylinder, arrange the material well. Then feed them into the feeding trough one by one, waiting for the feeding order. (Note: Automatic loading can be realized for round ones, manual loading for square ones and hexagonal ones.)

C－2 Automatic head extrusion machine

The head extrusion machine is composed of extrusion clamping die, oil cylinder, hydraulic station and machine base. The extrusion head length is controllable.

C－3 Pulling host

Drawing The drawing machine is a cold drawing equipment with double chain transmission, mechanical chuck and hydraulic support. It consists of mold base, mold frame, drawing trolley, support frame, hydraulic station system, transmission chain, reducer, motor and machine base. The drawing speed is controlled by frequency conversion.

1. Main motor power: 132Kw; frequency conversion control;

2. Effective stroke: 8 meters

3.Hydraulic lifting of the support frame

C-4 unloading mechanism

The unloading mechanism is composed of hydraulic support, feeding and material rack. The hydraulic support consists of six groups. The feeding mechanism sends the material into the receiving rack. The frame is 8 meters long, located on the side of the chain pulling machine, and catches the workpieces from the unloading mechanism.

C-5 collection rack

The support material tape is electrically adjustable. Shelf length: 8 meters

C-6 electric control system 1 set

1. Mitsubishi PLC

2. Weilun (Taiwan) touch screen

3. Inverter (China)

4. The main low-voltage accessories adopt Schneider brand servo motor

The double chain drawing machine has the following advantages:

(1) The drawing center line is consistent with the equipment center line, the drawing process is stable, and the dimensional accuracy, surface quality and flatness of the product are high;

(2) The single-chain drawing machine needs a feeding mechanism. After being drawn by the double-chain drawing machine, the pipe material falls directly from the gap between the two chains, and enters the material basket through the inclined slide plate of the drawing machine or is output by the horizontal output mechanism. Easy unloading;

(3) Since the trolley does not need to be hooked, the double-chain drawing machine can not only draw large-sized bars with a larger tonnage, but also draw small bars, and there will be no problem that the trolley hook cannot be lifted or unhooked because the pulling force is too small , a wide range of applications;

(4) The double chain drawing machine cancels the trolley return mechanism and the feeding mechanism, the trolley has no hooks and parts related to the hooks, the structure is simple, and the maintenance is easy.
