Hydraulic Uncoiler Straightener

Title: Hydraulic uncoiler Straightener

This Hydraulic feeding line is suitable for coil material thickness from 0.1 - 0.6mm.

Hydraulic uncoiler Straightener USHL Series features:

1. This series of straightening machine is specially designed for thin materials such as stainless steel, copper, iron and aluminum, which can achieve perfect leveling effect.

2. The uncoiling and leveling machines are integrated, saving space, fast and convenient operation, double frequency conversion speed regulation and more stable operation.

3. All straightening wheels are made of SUJ2 imported material, heat treated with HRC60 °, then plated with hard chromium and ground to ensure the uniformity of hard chromium layer and the cylindricity tolerance of each shaft.

4. The correction and adjustment of the machine adopts a floating four-point balance fine adjustment device with a dial indicator, which can be found and leveled quickly.

5. In addition to the upper and lower correction rollers, the correction auxiliary wheel can be installed inside the correction machine to prevent the correction roller from bending and deformation due to excessive pressure, strengthen the correction strength and service life of the correction roller, and improve the requirements of plate surface flatness.

6. The upper and lower rollers of the machine adopt universal joints and gears with full transmission to avoid the disadvantages of power loss and scratching the material surface caused by the passive rotation of the rollers on the conventional machine.

7. The correction speed is controlled by the frequency converter and can be adjusted freely in combination with the feeding speed.

Hydraulic uncoiler Straightener USHL Series Technical Parameters

The stamping process of automobile parts generally includes four processes: drawing process, trimming process, punching process and flanging process. Each process corresponds to a set of molds. Sometimes, in order to save costs, a set of molds for the subsequent trimming and punching process are made and compressed into three processes.

The drawing process is the main forming process. Through the drawing process, the main shape of the parts is basically formed. In addition, the parts after drawing can obtain certain strength and stiffness through deformation strengthening.

The trimming process is mainly to cut off the excess auxiliary materials in the drawing process, such as drawing rib, process supplementary surface, etc.

As the name suggests, the punching process is to punch holes on parts. For some complex door inner plate molds, the punching process may need to punch more than 100 holes, which requires high precision and is difficult to process.
