Description

Technical Field

[0001] The utility model belongs to the technical field of edge pressing and shrinking, and particularly relates to an edge pressing and shrinking device. Background Art

[0002] When processing a fire extinguisher, the cylinder and the upper and lower covers need to be processed separately and then assembled together. When processing the bottom cover, the bottom cover needs to be pressed and shrunk to facilitate its assembly with the cylinder, which requires the use of a pressing and shrinking device.

[0003] During processing, the existing edge pressing and shrinking device places the workpiece into the lower die base, presses it through a hydraulic device, and then brings it into contact with the rotating edge pressing disk to perform edge pressing and shrinking. During the production process, the workpiece and the lower die base are easily stuck, resulting in the inability to unload the material. Although reducing the fit between the workpiece and the lower die base can facilitate unloading, it will cause the workpiece to idle, affecting the processing quality. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] Example 1:

[0019] like Figure 1-3 As shown, a side pressing and shrinking device includes an operating table 100. The operating table 100 is C-shaped. A hydraulic cylinder 101 is fixedly installed on the upper end of the operating table 100. The output end of the hydraulic cylinder 101 slides through the upper part of the operating table 100 and is fixedly installed with a top block 102. A first motor 103 is fixedly installed inside the lower side of the operating table 100. The output shaft of the first motor rotates and passes through the operating table and is fixedly installed with a lower die base 104, thereby completing the installation and compression of the workpiece. A demoulding mechanism is provided on the top block 102.

[0020] The demoulding mechanism includes a connecting box 105, which is slidably mounted on the top block 102. A limit block 106 matching the inside of the connecting box 105 is fixedly mounted on the top block 102. A demoulding ring 107 is fixedly connected to the lower side of the connecting box 105. A loading port 108 is provided between the connecting box 105 and the demoulding ring 107. By setting up the demoulding mechanism, after the processing is completed, the workpiece can be separated from the lower mold base 104 by lifting the top block 102.

[0021] A pressing mechanism is provided on the front side of the operating table 100, and the pressing mechanism includes a driving box 200. A movable groove 201 is opened on the front part of the operating table 100, and the driving box 200 is slidably installed in the movable groove 201. A movable motor 202 is provided on the rear side of the movable groove 201. The output end of the movable motor 202 is fixedly installed with a screw 203 that penetrates into the movable groove 201, and the screw 203 is threadedly connected to the driving box 200. A second motor 204 is fixedly installed in the driving box 200, and the output shaft of the second motor 204 rotates and passes through the driving box 200 and is fixedly installed with a pressing disk 205. By setting a pressing plate mechanism, the workpiece can be pressed.

[0022] The driving box 200 and the moving slot 201 are both trapezoidal, so that the operation of the driving box 200 is more stable.

[0023] A turntable 301 is rotatably mounted on the lower end of the top block 102 so as not to affect its rotation when the workpiece is pressed.

[0024] The surface of the lower die base 104 is provided with anti-skid grooves to prevent the workpiece and the lower die base 104 from slipping and affecting the processing.

[0025] The internal space of the loading port 108 is circular and concentric with the lower die base 104 , and the space matches the size of the workpiece, facilitating the positioning of the workpiece.

[0026] When this embodiment is in use, the workpiece is placed in from the loading port 108 and fits with the interior, the hydraulic cylinder 101 is started, and the hydraulic cylinder 101 drives the top block 102 and the demoulding mechanism to move downward, pressing the workpiece into the lower die base 104, and the first motor 103 is started to make the lower die base 104 drive the workpiece to rotate, and the second motor 204 is started to make the pressure plate 205 rotate, and the moving motor 202 is started to make the screw 203 rotate, and the screw 203 drives the drive box 200 to move, and the workpiece is pressed and shrunken by the pressure plate 205. After the processing is completed, the various components are reset. During the reset process, the top block 102 moves upward, and the limit block 106 at its lower part contacts the upper side of the interior of the connecting box 105 and drives it to move upward, and the connecting box 105 drives the demoulding ring 107 to move upward, thereby separating the workpiece from the lower die base 104.
