2020 Ultimate Edition: W11H Series Three-roller Plate Rolling Machine Function Detailed Explanation

Foreword:

W11H series three-roller rolling machine is a new type of metal shaping equipment developed in the 1990s. It has been popularized because of its novel structure, reasonable force and multiple functions.

Chinese companies introduced the technology from Sweden in 1992, and the successful trial production filled the gap in China.

Through digestion, absorption, and innovative design, the W11H series three-roller plate rolling machine has occupied the domestic market in China and is also sold back to Europe and Nepal, Singapore, Hong Kong and other countries and regions.

W11H series three-roller plate rolling machine has extensive market and development prospects, and is accepted by more and more users

However, in the early stage of equipment promotion, some users did not know enough about the machine's performance, and the reel method was not essential, failed to make full use of the machine's functions, and some caused unnecessary economic losses.

For example, if a company in a certain city purchased the W11HNC-60 x 3 200 arc-down three-roller rolling machine, the operator only knew that the symmetrical three-roller rolling machine was used, resulting in a long remaining straight edge at the end of the sheet and serious material waste . Another example is that after a company in a city purchased the W11HNC-60x2 500 arc-down three-roller rolling machine, because the company did not fully understand the machine's functions and did not have professional operators, it rolled a cylindrical workpiece that did not have the required parameters. It is considered that there is a problem with the function of the machine and a return is required.

After operating on-site by the production company and training the personnel of the company, the two sides shook hands until they grasped.

 ,Function analysis of W11H series three-roller rolling machine

 Many functions are the outstanding features of the W11H series three-roller plate rolling machine, mainly in the following aspects.

1.With the function of symmetrical three-roller rolling machine

  The upper roller of W11H series three-roller rolling machine is fixed and rotated, and the two lower rollers are lifted around the fixed central arc respectively. The two lower rolls are conveniently adjusted through the operation table, so that the three work rolls are symmetrically formed, which constitutes a symmetrical plate rolling model with the function of a symmetrical three roll plate rolling machine.

2. No need to turn around to complete pre-bending and round forming at both ends of the sheet.

The two lower rollers of the W11H series three-roller plate rolling machine can be lifted and lowered individually by arc. During operation, one lower roller is raised to clamp the sheet, and the other lower roller is in the lower part to support. That is, an asymmetric three-roller plate rolling machine is formed to realize pre-bending of one end of the sheet. The asymmetrical three-roller rolling machine at the other end of the pre-bent sheet is formed by lowering the lower roll of one side of the pre-bent sheet and lowering the bottom of the other side. Therefore, the W11H series three-roller plate rolling machine is a combination of two asymmetrical three-roller plate rolling machines.

3.Able to roll conical workpiece

A roll cone device is installed at the end of the upper roll body at the discharge side of the equipment. The device is composed of a sleeve, a fixed ring and a friction key. The principle is to reduce the friction to achieve the same speed at both ends of the sector plate, and complete the roll forming of the conical workpiece.

4.With sheet centering function

The sheet alignment of the ordinary three-roller rolling machine is mainly based on the operator's experience. The work efficiency is low and the waste is easy to produce. On the side of W11H series three-roller plate rolling machine, there is a hydraulically operated turning and centering mechanism. The busbar of the sheet is accurately parallel to the axis of the working shaft to avoid skewing of the sheet.

5, wide range of coils

Ordinary three-roller rolling machine has two lower rollers as active rollers and upper rollers as passive rollers. It is easy to slip when rolling thin plates and small-diameter workpieces.

The standard stipulates that the thickness of the coil can be less than 1/3 of the maximum coil thickness specified by the parameter; the minimum roll diameter is 2.5 times the diameter of the upper roll, and the upper and two lower rolls of the W11H series three-roll coiling machine are both Main drive roller. That is, three-roller full drive, which allows to roll sheets with a minimum thickness of 1/5 of the maximum coil thickness specified by the parameter. The minimum roll diameter can reach 1.25 times the upper roll diameter. It can also be equipped with inner and outer brackets. To meet the rolling of thin-plate large-diameter workpieces.
