Introduction of Components

Manual Uncoiler


Usage:It is used to support the steel coil and uncoil it in a turnable way. The steel coil is uncoiled by hand.

Loading capacity:1-2T

Inner diameter: 450-508mm

Entry Beach

Put the raw material(steel plate) through the beach to manufacture and process, it can guarantee that the products are neat, parallel and everything is uniformity. Please refer to the equipment regulation to know the function of locate angle iron.

 Forming Machine


In order to keep the product shape and precision, adopts welded sheet structure, motor reducer drive, chain transmission, roller surfaces polishing, hard plating , heat treatment and galvanizational treatment . The polished surface and the heat treatment towards the molds also can keep the molding plate surface smooth and not easy to be marked when it is being stamped.

Material of rollers:45# steel, surface hard chromium plating.

Main power: 4kw(cycloidal planetary gear speed reducer)

Shearing Mechanism


It adopts the hydraulic drive and automatic location to decide the dimension and cut the target products.

Material of blades: Cr12

Components:It contains one set of cutting tools, one hydraulic tank and one cutter machine.


Hydraulic Station


It is controlled by gear wheel oil pump. After filling the hydraulic oil into the hydraulic oil tank ,the pump drive the cutter machine to begin the cutting job.


Hydraulic oil: 40#

Components: The system includes a set of hydraulic tank , a set of hydraulic oil pump, two hydraulic pipes.and two sets of electromagnetism valves.

Computer Control Cabinet

It adopts PLC to control. The target piece`s length is adjustable and digit of it can be adjusted. Computed mode has two modes: automatic and manual one. The system is easy to operate and use.


One counter gauges length, pulses, and decides length.

Products receiving tables


It adopts welded steel and supported roller to transmit the products,which is used to collect the finished products.
