Description

Technical Field

[0002] During the processing of stainless steel strips, in order to make the stainless steel strips reach the corresponding use thickness, it is often necessary to extend the stainless steel strips, and an extending mechanism is used when extending the stainless steel strips.

[0003] The stretching mechanism currently used to stretch stainless steel strips mainly consists of an stretching frame, two pressure rollers installed on the frame, and a power motor installed on the frame for driving the pressure rollers to rotate. Although the stretching mechanism of the above structure can realize the stretching processing of stainless steel strips, since the stainless steel strip reaches the final thickness through one rolling under the above processing method, it is easy for the one-time stretching amount to be too large during the stretching process of the stainless steel strip to cause stress concentration in the stretched stainless steel strip, making the stainless steel strip prone to bending deformation after stretching, thereby resulting in poor stretching quality of the stainless steel strip. Utility Model Content

[0013] By adopting the above technical solution, the electric telescopic rod is mainly used to adjust the height of each dynamic pressure roller, so as to control the distance between the dynamic pressure roller and the fixed pressure roller.

[0014] Furthermore, a gap is reserved between the outer wall of the dynamic pressure roller and the outer wall of the fixed pressure roller, and the gaps between the three dynamic pressure rollers and the fixed pressure roller decrease from left to right.

[0015] By adopting the above technical solution, this design can extend the stainless steel strip under the action of three consecutive rolling processes, thereby avoiding deformation and bending of the stainless steel strip after the extension process.

[0017] By adopting the above technical solution, during the extension process, the lubrication pump will pump the lubricating liquid in the liquid storage box into the liquid storage chamber so that it can be sprayed on the dynamic pressure roller through the Y-shaped spray cover. At the same time, the lubrication pump will also pump the lubricating liquid into the lubrication nozzle so that the lubrication nozzle can be sprayed on the fixed pressure roller, thereby ensuring the oil spray lubrication operation of the dynamic pressure roller and the fixed pressure roller during the extension process.

[0018] Furthermore, an operation panel is connected to the middle of one side wall outside the mounting cover by bolts, and the operation panel is electrically connected to the motor 1, the motor 2, the lubrication pump and the electric telescopic rod.

[0019] By adopting the above technical solution, the operation panel mainly controls the coordinated work of the motor 1 and the motor 2 by controlling the on-off of the circuit, so as to perform efficient stretching processing on the stainless steel strip.
