[0005] Preferably, the compression spring is sleeved on the outer wall of the positioning post.

[0006] Preferably, the stripping plate is detachably connected to a limiting seat, the limiting seat has a limiting groove on its edge, the stripping seat has a flange, and the flange extends between the limiting seat and the stripping plate.

[0007] Preferably, the lower die base is provided with a first height limiting post on the side facing the stripper plate, and the lower die base is also provided with a plurality of second height limiting posts that are slidably connected to the stripper plate. The second height limiting posts are provided with limit caps, and the limit seats are provided with clearance grooves corresponding to the limit caps.

[0008] The beneficial effects of this utility model are: the tooling is structurally compatible with the wear-resistant sleeve and the mixing tank, and the installation of the wear-resistant sleeve is completed by stamping instead of manual labor, thus solving the problems of high labor intensity and incomplete installation by manual installation.

[0016] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0017] This utility model provides, for example Figure 1-4 The wear-resistant sleeve stamping fixture shown includes an upper die holder 11 and a lower die holder 21, with multiple guide posts 12 disposed between the upper die holder 11 and the lower die holder 21. The upper die holder 11 is equipped with a drive device 13. An upper clamping plate 14 is slidably connected to each guide post 12. The upper clamping plate 14 is connected to the piston rod of the drive device 13, and a punch 15 is disposed on the upper clamping plate 14. Driven by the drive device 13, the upper clamping plate 14 drives the punch 15 to reciprocate along the guide posts 12, completing the stamping action. The drive device 13 can be a cylinder, or a conventional stamping machine can be referenced.

[0018] The lower die base 21 is provided with a lower die column 26, and the lower die column 26 is provided with a positioning head 27. The positioning head 27 is clearance-fitted with the bottom through hole of the mixing tank, and the gap between the two is used to accommodate the wear-resistant sleeve. A material support platform 28 is formed between the positioning head 27 and the lower die column 26, which is used to support the wear-resistant sleeve and the end face of the bottom through hole of the mixing tank. The punch 15 is provided with a positioning groove 16 on the side facing the lower die base 21, so that one end of the punch 15 forms a ring shape, and the positioning head 27 cooperates with the positioning groove 16. When punching downward, the ring structure at one end of the punch 15 can apply pressure to the wear-resistant sleeve around the positioning head 27.

[0019] like Figure 5 , 6 As shown, the first wear-resistant sleeve 30a can be inserted into the positioning head 27 first, and the first wear-resistant sleeve 30a can be placed on the material support platform 28. Then, the bottom through hole of the mixing tank is inserted into the outer wall of the first wear-resistant sleeve 30a. Then, one end of the second wear-resistant sleeve 30b is stuck in the gap between the bottom through hole of the mixing tank and the positioning head 27. The drive device 13 is started to push the punch 15 downward to impact and press both wear-resistant sleeves into the bottom through hole of the mixing tank to complete the punching.

[0020] The lower mold base 21 is also provided with a plurality of positioning posts 22 and a stripper plate 23 slidably connected to the positioning posts 22. The stripper plate is provided with a stripper seat 24 extending toward the upper mold base 11, and the stripper plate 23, the stripper seat 24 and the lower mold post 26 are slidably connected. A compression spring 25 is also provided between the stripper plate 23 and the lower mold base 21, and the compression spring 25 can be sleeved on the outer wall of the positioning posts 22. Specifically, the stripper plate 23 is bolted to a limiting seat 29, the limiting seat 29 is provided with a limiting groove on its edge, the stripper seat 24 is provided with a flange, and the flange extends between the limiting seat 29 and the stripper plate 23. After the limiting seat 29 is fixed to the stripper plate 23, it presses the stripper seat 24 tightly. Figure 5 As shown, the limiting seat 29 and the unloading seat 24 are used to support the edge of the mixing tank and the side wall of the bottom through hole, respectively. During the stamping, the compression spring 25 is compressed. After the stamping is completed, the punch 15 is reset. The compression spring 25 releases elastic potential energy to move the unloading plate 23, the limiting seat 29, and the unloading seat 24 upward. They also push the mixing tank and the wear-resistant sleeve away from the positioning head 27 through the edge of the mixing tank and the side wall of the bottom through hole, thus completing the unloading.

[0021] Preferably, the lower die base 21 is provided with a first height limiting post 211 on the side facing the stripper plate 23, and the lower die base 21 is also provided with a plurality of second height limiting posts 212 slidably connected to the stripper plate 23. The second height limiting posts are provided with limit caps 213 to limit the stroke of the stripper plate 23. The limit seat 29 is also provided with a relief groove corresponding to the limit cap 213 to avoid interference.

[0022] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
