[0002] Roll pressing refers to a process of forming various complex parts by relying on the plastic movement characteristics of materials and adopting the principle of rolling extrusion. Compared with cutting and grinding processes, the roll forming process not only has high production efficiency and saves materials, but also has high product strength and stable quality. Roll pressing dies are the dies used in the roll forming process. When manufacturing the crossbeam seal plate of the front row seats of an automobile, a roll pressing die is required to roll process the blank.

[0003] When the roll pressing die processes the blank, the roll pressing die moves relative to the blank, and a large amount of heat will be generated by the friction between the roll pressing die and the blank. After the roll pressing die works for a long time, the increase in the die temperature is likely to cause the die to deform, thereby reducing the accuracy of the die, shortening the service life of the die, and affecting the quality of the roll forming process; therefore, a front and rear roll pressing beam die is proposed.

[0024] Referring to Figures 1-5 , an embodiment of the present invention is a front and rear rolling beam mold, which includes a mounting base 1. There are two mounting bases 1, and hydraulic cylinders 2 are fixedly connected to the upper sides of both. On one side of the two mounting bases 1 facing each other, there is a slide groove 6. The output end of the hydraulic cylinder 2 is located in the slide groove 6 and is fixedly connected to a slide block 7. The slide block 7 is slidably connected to the slide groove 6. Between the mounting base 1 below the slide groove 6 and the two slide blocks 7 on both sides, there is a rolling mechanism 4. On the mounting base 1 behind the rolling mechanism 4, there is a guide roller 5 rotatably connected. The guide roller 5 and the lower rolling mechanism 4 are in the same horizontal position. The upper and lower rolling mechanisms 4 are arranged in parallel. By means of the hydraulic cylinder 2, the upper rolling mechanism 4 can be driven to move up and down, so that it can manufacture crossbeam sealing plates of different thicknesses, with good flexibility;
