Two stamping die heads 7 are arranged side by side in the horizontal direction. The clamping posts 31 and the through holes on any one of the limit seats 4 correspond to the stamping die heads 7 one by one and are coaxial with the stamping die heads 7. The workbench 1 is horizontally arranged, and the sliding clamping seat 3 and the limit seats 4 are both vertically arranged.

[0034] In a specific embodiment of the present utility model, the punching device for the side wall of the pot body further includes a lifting frame 5 for supporting the pot body 6. The lifting frame 5 is slidably installed on the workbench 1 and is located on one side of the stamping cylinder 2. An operation hole 51 is provided in the middle of the lifting frame 5, and the sliding clamping seat 3 and several limit seats 4 are both arranged in the operation hole 51. A plurality of adjusting bolts 52 are threadedly connected to the bottom surface of the workbench 1, and the plurality of adjusting bolts 52 all penetrate through the workbench 1 and are rotatably connected to the lifting frame 5. A plurality of support columns 11 are also provided on the bottom surface of the workbench 1.

[0035] In a specific embodiment of the present utility model, a sliding groove 12 is provided on the workbench 1 for slidably clamping the bottom of the sliding clamping seat 3. A fixed seat 13 parallel to the sliding clamping seat 3 is further provided on the top surface of the workbench 1. A sliding column 32 fixedly connected to and passing through the fixed seat 13 is provided on the sliding clamping seat 3. Sliding springs 14 are provided between the sliding clamping seat 3 and the fixed seat 13 and in the sliding groove 12.

[0036] In this embodiment, a receiving groove for slidably installing the clamping post 31 is provided on the sliding clamping seat 3. A top spring 33 connecting the sliding clamping seat 3 and the clamping post 31 is provided in the receiving groove, and the clamping post 31 penetrates through and positions the punching hole of the pot body 6.

[0037] In a specific embodiment of the present utility model, a material leakage groove 15 is provided on the workbench 1 on the side of any one of the limit seats 4 away from the stamping cylinder 2. A collecting groove 16 communicating with a plurality of material leakage grooves 15 is further provided on the workbench 1. A collecting box 17 for recycling stamping waste is provided in the collecting groove 16.

[0038] In this embodiment, the surface of the limit seat 4 on the side close to the stamping cylinder 2 is an arc surface, and the radius of the arc surface of the limit seat 4 on the side close to the stamping cylinder 2 is greater than the radius of the arc surface of the other limit seat 4. The surface of the sliding clamping seat 3 on the side away from the stamping cylinder 2 is an arc surface, and the radius of the arc surface of the sliding clamping seat 3 is less than or equal to the radius of the arc surface of the limit seat 4. The sliding groove 12 is an inverted T-shaped groove. Here, as long as the relevant performance functions of the limit seat 4 and the sliding clamping seat 3 can be realized, they are within the protection scope of this application document.

[0039] Compared with the prior art, this punching device for the side wall of the pot body can adaptively change the position of the limit according to the size of the pot body 6 through the setting of the sliding clamping seat 3, with a wider application range. Through the setting of the clamping column 31 on the sliding clamping seat 3, the end of the pot body 6 that has been punched is fixed. At the same time, by cooperating with the limit seat 4 and the stamping cylinder 2, the other end of the pot body 6 is punched. Since the clamping column 31 is coaxially arranged with the through hole, the mounting holes formed by punching on the pot body 6 are coaxial and centrosymmetric on the pot body 6. Flipping the pot body 6 and buckling it on the sliding clamping seat 3 and the limit seat 4 can realize the stamping of the mounting holes, with simple operation, no need for manual scribing, higher punching accuracy, and effectively improving the punching efficiency. Through the setting of the lifting frame 5, the depth of the punching position inside the pot body 6 can be adjusted, expanding the use range of the device. It is controlled by the adjusting bolt 52, with a simple structure, convenient adjustment, low purchase and use cost, and suitable for wide promotion.

[0040] The working process of the punching device for the side wall of the pot body of the present utility model is as follows: Invert the pot body 6 on the lifting frame 5. According to the position where punching is required, adjust the height of the lifting frame 5 by rotating the adjusting bolt 52. During the adjustment process, pay attention to reciprocally adjusting diagonally to ensure that the top surface of the lifting frame 5 is in a horizontal position. After the adjustment is completed, make one end of the pot body 6 abut against the arc surface of the sliding clamping seat 3. At this time, the pot body 6 squeezes the clamping column 31 into the accommodating groove, and the ejecting spring 33 is compressed. Pull the pot body 6 and clamp the other end of the pot body 6 on the arc surface of the limit seat 4. At this time, both the limit seat 4 and the sliding clamping seat 3 are located inside the pot body 6, and the sliding spring 14 is compressed to different degrees according to the different specifications of the pot body 6. And according to the different specifications and sizes of the pot body 6, the other end of the pot body 6 is sleeved on the limit seat 4 at different positions.

[0041] After the pot body 6 is fixed, press the bottom of the pot body 6 by hand and start the stamping cylinder 2. The stamping cylinder 2 punches on the pot body 6 through the extension rod 8 and the stamping die head 7. If the diameter of the pot body 6 is larger, then sleeve the pot body 6 on the outer limit seat 4. At this time, the stamping cylinder 2 only needs to extend a short distance to complete punching through the stamping die head 7. If the diameter of the pot body 6 is smaller, then sleeve the pot body 6 on the inner limit seat 4. At this time, the stamping cylinder 2 needs to extend a longer distance and needs to drive the stamping die head 7 through one or more limit seats 4 and then approach the pot body 6 for punching.

[0042] After punching one side of the pot body 6, remove the pot body 6. After rotating the pot body 6 and placing it upside down on the lifting frame 5, fix both ends of the pot body 6 on the sliding clamping seat 3 and the limit seat 4. Then, slightly adjust the position of the pot body 6 to align the installation holes obtained by punching with the receiving grooves. At this time, the clamping post 31 is pushed out through the installation holes under the action of the ejecting spring 33 to position and fix the pot body 6. After the positioning is completed, press the bottom of the pot, start the stamping cylinder 2, and punch holes at the other end of the pot body 6. After the punching is completed, remove the pot body 6, and the sliding spring 14 drives the sliding clamping seat 3 to move along the sliding groove 12 to the initial position.

[0043] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts between the various embodiments, reference can be made to each other. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple.

[0044] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
