Embodiment Construction

[0030] figure 2 It is a schematic diagram of an embodiment of the cold rolling mill of the present invention. Such as figure 2 As shown, the cold rolling mill includes a motor and a series of transmission devices (not shown in the figure), this part is the prior art, and will not be repeated here. At the end of the transmission is a gear distributor 3, the input shaft of the gear distributor 3 is one, after passing through the gear distributor 3, it is converted into two output shafts 31, 32, the rolling mill in the prior art is generally two The output shafts 31, 32 are parallel to each other, and both are respectively connected with a roll. And the cold rolling mill provided by the present invention provides a kind of steel plate that can roll flat steel plate into the trapezoidal cross section with certain inclination, therefore requires to make two rolls form an angle, but how to make rolls form an angle is always the basic question A difficult point in the industry, ...

Abstract

The invention provides a cold mill, comprising a power device, paired rollers and drive devices that are arranged top and bottom; the drive device comprises a gear distributor; and the gear distributor is provided with two output shafts and an angular adjustment mechanism for adjusting the angle between the paired rollers. The invention also provides a method for producing a flange by using the cold mill. The cold mill is capable of rolling a steel plate into the trapezoidal cross-section shaped steel plate with a certain rake and avoiding the deformation of the steel plate during the cold rolling process. The operation is easy and convenient. The flange production method is capable of avoiding the heating procedure and saving the energy, meanwhile, the quality of the produced flange is steady.

Description

technical field [0001] The invention relates to a mechanical device and a processing method, in particular to a cold rolling mill and a flange manufacturing method using the cold rolling mill. Background technique [0002] In some specific cases, it is necessary to roll long strips of steel plates into steel plates with trapezoidal cross-sections with different thicknesses to meet the requirements for further processing. In the prior art, people generally use a hot rolling process to achieve this, but the hot rolling process requires the steel plates to be processed. Heating, which will cause changes in the material of the steel plate and consume a lot of energy. In addition, flanges are widely used in the machinery industry, such as for making concrete pipe pile end plates. In the prior art, there are mainly three methods for making flanges: the first one is the gas cutting method, such as figure 1 As shown, a number of flanges 12 are cut out on the large steel plate 1, a...
