[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Referring to Figures 2-4 , the utility model provides an embodiment: a kind of cold-rolled die steel castings of quick disassembly and assembly convenient to it, including support frame 1, the bottom end of support frame 1 is fixedly connected with guide rail 2, the inside of two guide rails 2 is provided with lower pressing plate 3, the front end of support frame 1 is fixedly connected with fixed block 9, the front side of lower pressing plate 3 is fixedly connected with hook sliding block 10, C-shaped fixing frame 11 is fixedly connected in the top side of fixed block 9, the top side of C-shaped fixing frame 11 is slidably connected with two support sliding rods 12, the bottom side of two support sliding rods 12 is fixedly connected with pressing block 14, and pressing block 14 is arranged on the top side outer wall of hook sliding block 10, the outer wall of support sliding rod 12 is equipped with spring 13, to be used for the fixing between the front side of lower pressing plate 3 and support frame 1, insert shell 4 is fixedly connected in the rear side of lower pressing plate 3 and support frame 1, C-shaped slot is formed in the similar side of two insert shells 4, and two C-shaped slots are connected by C-shaped insert shaft 5, to be used for the fixing between the rear side of lower pressing plate 3 and support frame 1, the top side of support frame 1 is slidably connected with multiple limit sliding rods 7, the bottom end of multiple limit sliding rods 7 is fixedly connected with upper pressing plate 8, the top side of support frame 1 is provided with hydraulic cylinder 6, and the driving end of hydraulic cylinder 6 is fixedly connected in the top side of upper pressing plate 8;

[0025] Specifically, first, when the cold rolling operation of the steel castings is performed, the steel castings to be processed are placed on the top side of the lower pressing plate 3. Then, the hydraulic cylinder 6 is started, and at this time, the hydraulic cylinder 6 controls the upper pressing plate 8 and the limiting slide rod 7 to descend. As the upper pressing plate 8 gradually approaches the lower pressing plate 3, pressure is generated between the upper pressing plate 8 and the lower pressing plate 3, and the cold rolling of the steel castings is achieved by using this pressure. When the lower pressing plate 3 needs to be replaced, the C-shaped insertion shaft 5 is pulled out from the inside of the two insertion shells 4, and then the support slide rod 12 is pulled up, and the support slide rod 12 is compressed during the rising process. As the spring 13 is compressed, the pressing block 14 and the hook slide block 10 are disconnected, and then the lower pressing plate 3 is pulled out from the inside of the two guide rails 2, and then a new lower pressing plate 3 is inserted between the two guide rails 2. The new lower pressing plate 3 is inserted along the guide rail 2, and the guide rail 2 plays a guiding role to ensure that the lower pressing plate 3 can be accurately installed in place. The hook slide block 10 is inserted into the inside of the fixed block 9, and the pressing block 14 is clamped on the top side of the hook slide block 10 through the reset of the spring 13. In this way, the position of the lower pressing plate 3 can be preliminarily fixed, and finally the C-shaped insertion shaft 5 is inserted into the two C-shaped grooves on the same side of the two insertion shells 4. Through this operation, the lower pressing plate 3 is firmly fixed on the support frame 1 again. Through such a simple structure and operation, the lower pressing plate 3 can be quickly replaced. Avoid the problem that the replacement steps of the lower pressing plate 3 are too complex to affect the work efficiency. At the same time, during the operation of the entire device, the guiding effect of the guide rail 2 on the lower pressing plate 3 and the limiting effect of the limiting slide rod 7 on the lifting upper pressing plate 8 are very important. The guide rail 2 ensures that the lower pressing plate 3 always maintains the correct position during installation and work, and the limiting slide rod 7 ensures that the upper pressing plate 8 does not deviate during lifting, which facilitates the precise pressing between the upper pressing plate 8 and the lower pressing plate 3. This precise pressing helps to improve the quality of the precise cold rolling of the steel castings.

[0026] Referring to Figures 1-3 , one end of the spring 13 is connected with the C-shaped fixed frame 11, the other end of the spring 13 is connected with the top side of the fixed block 9, the top end of the limiting slide rod 7 is fixedly connected with a circular limiting plate, so as to avoid the disconnection between the limiting slide rod 7 and the support frame 1, the rear side of the lower pressing plate 3 is fixedly connected with a handle, and one end of the C-shaped insertion shaft 5 is fixedly connected with a hanging ring on the top side of the two support slide rods 12;

[0027] Specifically, the pressing block 14 can be clamped on the top side of the hook slide block 10 through the reset of the spring 13, and the lower pressing plate 3 can be pulled out and inserted through the handle, and the C-shaped insertion shaft 5 and the support slide rod 12 can be pulled out through the hanging ring.

[0028] Working principle: the steel castings to be processed are placed on the top side of the lower pressing plate 3, then the hydraulic cylinder 6 is started to control the descent of the upper pressing plate 8 and the limiting slide rod 7, the cold rolling of the steel castings is realized through the pressure between the upper pressing plate 8 and the lower pressing plate 3, when the lower pressing plate 3 needs to be replaced, the C-shaped insertion shaft 5 is pulled out from the inside of the two insertion shells 4, the spring 13 is compressed through the upward pulling of the supporting slide rod 12, the disengagement between the pressing block 14 and the hook slide block 10 is realized, the lower pressing plate 3 is pulled out from the inside of the two guide rails 2, the new lower pressing plate 3 is inserted between the two guide rails 2, the hook slide block 10 is inserted into the inside of the fixed block 9, the pressing block 14 is clamped on the top side of the hook slide block 10, the C-shaped insertion shaft 5 is inserted into the two C-shaped grooves on the same side of the two insertion shells 4, and the lower pressing plate 3 is fixedly installed on the supporting frame 1.
