Description

Technical Field

[0001] This utility model relates to the field of blind rivet processing technology, specifically a stamping device for preparing extrusion-type vent sealing plug blind rivets. Background Technology

[0002] The extrusion-type pore sealing plug blind rivet is a special type of blind rivet used to seal pores and achieve a fast connection. It is commonly used in aerospace, automotive manufacturing, shipbuilding, and electronic equipment manufacturing industries. The production and manufacturing process of blind rivets requires the use of a stamping device.

[0003] According to a mold for processing core-pulling rivets disclosed in patent publication number CN 214517138 U, the device positions the lower end of the forming mold body at the bottom of the fixed groove. Then, rotating the handle causes the lead screw to rotate, driving the support plate forward, so that the clamping plate fits against the outer wall of the forming mold body in a clamping state, thereby making the forming mold body more firmly fixed and avoiding affecting product quality during processing. The motor drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear to rotate, so that the rotating shaft drives the base to rotate slowly, thereby realizing the simultaneous processing of multiple materials and improving work efficiency. However, after long-term use, the clamping surface of the device can easily become smooth due to friction, which affects the subsequent fixing effect on the forming mold and thus affects the stability of the subsequent workpiece processing.

[0004] To address this issue, we propose a stamping device for preparing extrusion-type pore sealing plug core-pulling rivets. Utility Model Content

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] Example 1 like Figure 1-6 As shown, this utility model provides a technical solution: a stamping device for preparing an extrusion-type vent sealing plug core-pulling rivet, including a workbench 1, a mounting frame 2 fixedly installed on the upper part of the workbench 1, a hydraulic cylinder 4 fixedly installed on the upper part of the mounting frame 2, a punch 5 fixedly installed on the output end of the hydraulic cylinder 4 via a connecting block, and a connecting assembly 3 set on the upper part of the workbench 1. The connecting assembly 3 includes a fixing mechanism 31 set on the upper part of the workbench 1, a rotating mechanism 32 set on the upper part of the workbench 1, and a mounting frame 311 set on the upper part of the workbench 1. A threaded rod 312 is threadedly connected to the side of the mounting frame 311, and a fixing plate 313 is rotatably connected to the inner end of the threaded rod 312 via a bearing. A limit rod 314 is fixedly connected to one side of the fixing plate 313. A limiting block is fixedly connected to the outer end of the limiting rod 314. A convex groove 315 is provided at the bottom of the fixing plate 313. A convex column 316 is slidably connected to the inner wall of the convex groove 315. A pressing groove 317 is provided on one side of the convex column 316. An anti-slip plate 318 is fixedly connected to the outer side of the convex column 316. A rotating rod 319 is rotatably connected to the bottom of the fixing plate 313 through a bearing. A locking rod 3110 is movably connected to one end of the rotating rod 319. A knob is fixedly connected to the bottom end of the locking rod 3110. A first spring 3111 is fixedly connected to the bottom of the rotating rod 319. A locking groove is provided at the bottom of the fixing plate 313. An inner groove 3112 is provided on the inner wall of the convex groove 315. A pressing column 3113 is sleeved inside the inner groove 3112. A second spring 3114 is fixedly connected to the inner wall of the inner groove 3112.

[0017] In this embodiment, the limiting rod 314 is movably connected to the mounting frame 311, the bottom end of the first spring 3111 is fixedly connected to the knob, the snap-fit ​​rod 3110 is snap-fitted into the snap-fit ​​groove, and the inner side of the rotating rod 319 is fitted to the bottom of the convex column 316. Through the cooperation of the mounting frame 311, the threaded rod 312, the fixing plate 313, and the limiting rod 314, the forming mold body can be fixed. Under the action of the anti-slip plate 318, the mold body is less likely to slide after being fixed, which makes subsequent stamping operations easier. At the same time, through the cooperation of the convex groove 315, the convex column 316, the pressing groove 317, the rotating rod 319, the snap-fit ​​rod 3110, the first spring 3111, the inner groove 3112, the pressing column 3113, and the second spring 3114, it is easy to manually disassemble the anti-slip plate 318, which makes it easy to replace the anti-slip plate 318 with large wear in time, thereby achieving a better fixing effect on the forming mold body.

[0018] Furthermore, one end of the second spring 3114 is fixedly connected to the pressing post 3113, and the pressing post 3113 is in pressing contact with the pressing groove 317.

[0019] When fixing the molding die body, the device first manually passes the die body through the mounting frame 311 and places it in the placement slot on the upper part of the placement platform 324. Then, the adjusting rod fixed to the outer end of the threaded rod 312 is manually rotated, and under the limiting action of the limiting rod 314, the fixing plate 313, which is rotatably connected to the inner end of the threaded rod 312 via the bearing, can move inward, thereby pressing and fixing the molding die body. Furthermore, the anti-slip plate 318 prevents the die body from slipping after fixing, making subsequent stamping operations easier. Moreover, when the anti-slip plate 318 needs to be disassembled, the locking rod 3110 is manually pulled downward to separate it from the locking slot. Then, the rotating rod 319 is manually rotated away from the bottom of the convex post 316, and then the die body can be manually... The anti-slip plate 318 is removed, making it easier to replace the worn anti-slip plate 318 manually. This also provides a better fixing effect on the molding die. When installing the anti-slip plate 318, firstly, the convex post 316 fixed to one side of the anti-slip plate 318 is engaged with the convex groove 315 manually. Then, the anti-slip plate 318 is pushed upward. When the convex post 316 and convex groove 315 are fully engaged, the second spring 3114, under the action of elasticity, can make the pressing post 3113 press against the pressing groove 317, thus providing auxiliary fixing for the anti-slip plate 318. Then, the rotating rod 319 is rotated manually, and the locking rod 3110 is engaged with the locking groove. Then, the first spring 3111, under the action of elasticity, can make the locking rod 3110 engage with the locking groove, thus fixing the anti-slip plate 318. The installation operation is then completed.

[0020] Example 2 Based on Example 1, a preferred embodiment of the stamping device for preparing the extrusion-type vent sealing plug core-pulling rivet provided by this utility model is as follows: Figures 1 to 6 As shown: The rotating mechanism 32 includes a motor 321 fixedly mounted on the bottom of the workbench 1 by a fixed frame. The output end of the motor 321 is fixedly connected to a rotating shaft 322. The top outer wall of the rotating shaft 322 is fixedly connected to a mounting rod 323. The outer wall of the rotating shaft 322 is fixedly connected to a placement platform 324. An annular groove 325 is opened on the upper part of the workbench 1. A support column 326 is slidably connected to the inner wall of the annular groove 325. A ball bearing 327 is movably connected to the bottom of the support column 326.

[0021] In this embodiment, the rotating shaft 322 is rotatably connected to the worktable 1 via a bearing, the mounting rod 323 is fixedly connected to the mounting frame 311, and the upper part of the placement table 324 is provided with a placement groove, and the placement groove is provided with a forming mold body. Through the cooperation of the motor 321, the rotating shaft 322, the mounting rod 323, the placement table 324, the annular groove 325, the support column 326, and the ball bearing 327, the placement table 324 can be rotated, thereby enabling the processing of multiple workpieces and increasing the applicability of the device.

[0022] Furthermore, the top of the support column 326 is fixedly connected to the placement platform 324.

[0023] Once the forming mold is fixed, the material is placed inside the mold manually. Then, the hydraulic cylinder 4 drives the punch 5 to move downwards, allowing for the stamping operation of the material. Subsequently, the core-pulling rivet can be prepared. The motor 321 drives the rotating shaft 322 to rotate, which causes the mounting rod 323, which is fixedly connected to the outer wall of the top of the rotating shaft 322, to drive the mounting frame 311 to rotate synchronously. This allows for the processing of multiple workpieces, increasing the applicability of the device. Furthermore, the support column 326 and the ball bearings 327 provide support for the placement table 324 and reduce the relative friction between the placement table 324 and the worktable 1, thereby reducing the wear and tear on the motor 321 and extending its service life.
