[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3A high-precision anti-deformation rolling processing device for threaded steel in this embodiment includes a support frame 1, a cylinder 4 is arranged in the support frame 1, a mounting plate 5 is fixed to the output end of the cylinder 4 and the inner bottom of the support frame 1, a rolling mold 3 is arranged on the mounting plate 5, and a mounting mechanism 2 is arranged on the mounting plate 5.

[0021] The mounting mechanism 2 includes a slide groove 208, a limit groove 207 and a motor 201. Two slide grooves 208 are provided in the mounting plate 5. A threaded rod 205 is arranged in the middle of the slide groove 208. The threads on the two threaded rods 205 have the same direction. The threaded rods 205 are threadedly connected with a limit block 206 that can move left and right. A spring 202 is sleeved on the threaded rod 205. Driven bevel gears 204 are fixed on opposite sides of the two threaded rods 205. A driving bevel gear 203 is rotatably installed in the mounting plate 5. The driving bevel gear 203 is located in the middle of the mounting plate 5, and driven bevel gears 204 are meshed on both sides of the driving bevel gear 203.

[0022] The rolling die 3 is provided with a limiting groove 207 engaged with the limiting block 206 , and the mounting plate 5 is fixed with a motor 201 for driving the active bevel gear 203 to rotate.

[0023] The device starts the motor 201, the motor 201 drives the active bevel gear 203 to rotate, the active bevel gear 203 engages with the driven bevel gears 204 on both sides, and then the driven bevel gears 204 drive the threaded rod 205 to rotate, and then the threaded rod 205 drives the limit blocks 206 on both sides to move relative to each other, so that the limit blocks 206 squeeze the spring 202, so that the limit blocks 206 are engaged with the limit grooves 207.

[0024] The limiting block 206 is L-shaped, so as to abut against the limiting groove 207 to limit and fix the rolling mold 3.

[0025] At the same time, the upper end of the limiting block 206 is slidably connected to the upper end of the limiting groove 207, limiting the rotation tendency of the limiting block 206 itself and making it move horizontally.

[0026] The working principle of the above embodiment is:

[0027] When the rolling die 3 needs to be replaced, the active bevel gear 203 is driven to rotate by starting the motor 201, and the active bevel gear 203 engages with the driven bevel gears 204 on both sides, and then the driven bevel gear 204 drives the threaded rod 205 to rotate, and then the threaded rod 205 drives the limit blocks 206 on both sides to move apart, and the spring 202 exerts a thrust on the limit block 206, so that the limit block 206 no longer abuts the limit groove 207 during disassembly, and moves to the outside of the limit groove 207, thereby disassembling the rolling die 3.

[0028] On the contrary, when the rolling mold 3 needs to be installed, the motor 201 is reversed so that the threaded rod 205 drives the limit blocks 206 on both sides to move relatively, so that the limit blocks 206 abut against the limit grooves 207, thereby limiting and fixing the rolling mold 3.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
