Description

Technical Field

[0001] The utility model relates to the technical field of rivet moulds, in particular to an upper hinge rivet mould which can be quickly disassembled and assembled. Background Art

[0002] Rivet is a mechanical connector used to connect two or more workpieces, usually used to fix metal plates or other materials. Its structure is relatively simple, generally consisting of a rivet body and a rivet cap (also called a rivet head). Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It includes blanking dies, punching dies, cutting dies, riveting dies, etc. Rivets are generally stamped and formed by stamping dies in production. At present, the precision and quality of rivets processed by stamping dies need to be improved.

[0003] After searching, it was found that the Chinese patent with the announcement number CN218452572U disclosed a rivet stamping die, including an upper die body, a lower die body, a mounting hole, a push rod, an elastic member, and a punching member. The upper die body and the lower die body are arranged along the same axis and are movably connected to the lower die body along the axial direction. The mounting hole is arranged at the center of the upper die body for placing the processing material. The push rod is arranged at the center of the lower die body along the vertical direction and extends into the mounting hole to contact the processing material. The upper end of the push rod is fixedly provided with a punching member for punching the processing material. The utility model can punch the processing material on the upper die body in the stamping device, so that the punching member can punch the center of the processing material, cooperate with the sliding of the upper die body relative to the lower die body, and then cooperate with the push rod to stamp the processing material into shape, thereby combining the stamping and punching in the rivet processing, thereby reducing a process and further improving the processing efficiency of the rivet.

[0004] The above utility model has the following problems:

[0005] 1. The existing rivet stamping die has a simple structure, cannot adjust the height of the floating center needle, and has poor adaptability. Different riveting tasks require floating center needles of different heights to ensure that the rivets are in the correct position, resulting in the need to replace different rivet dies to process rivets of different lengths and models, which wastes resources and affects the rivet processing efficiency.

[0006] Therefore, those skilled in the art provide a quickly disassembled upper hinge rivet die to solve the problems raised in the above background technology. Utility Model Content

[0007] The utility model aims to provide a quick-disassembly upper hinge rivet die to solve the problems raised in the above-mentioned background technology.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A quickly disassembled upper hinge rivet mold comprises a floating cylinder and a base, wherein a sleeve rod is fixedly connected to the surface of the base, and the outer diameter of the floating cylinder and the inner diameter of the sleeve rod cooperate with each other, a limiting mechanism for fixing the floating cylinder is arranged on the surface of the base, a movable block is slidably connected to the inner wall of the floating cylinder, a floating needle is fixedly connected to the top end of the movable block, and a connecting rod is fixedly connected to the bottom end of the movable block.

[0010] As a further solution of the utility model: a slide groove is provided on the inner side wall of the buoyancy tube, a slider is slidably connected to the inner side wall of the slide groove, and a lifting piece is fixedly connected to the side wall of the slider.

[0011] As a further solution of the utility model: a first return spring is fixedly connected to the surface of the lifting member, an upper end of the first return spring is sleeved outside the connecting rod, and a threaded rod is threadedly connected to the lower surface of the lifting member.

[0012] As a further solution of the utility model: the inner side wall of the buoyancy cylinder is further provided with an annular groove, the inner side wall of the annular groove is rotatably connected with an annular block, and the inner side wall of the annular block is fixedly connected with an adjusting bottom plate.

[0013] As a further solution of the utility model: the upper surface of the adjusting base plate is fixedly connected to the bottom end of the threaded rod, and the lower surface of the adjusting base plate is provided with a hexagonal groove.

[0014] As a further solution of the utility model: the limiting mechanism includes a fixing piece, a sleeve rod, a pressure block, a second return spring, a ball groove and a limiting ball, the surface of the base is slidably connected to the fixing piece, and the inner wall of the fixing piece is fixedly connected to the pressure block.

[0015] As a further solution of the utility model: a second return spring is fixedly connected to the surface of the base, and the second return spring is sleeved outside the sleeve rod.

[0016] As a further solution of the utility model: one end of the sleeve rod is provided with evenly arranged ball grooves, and a limiting ball is placed on the inner side wall of the ball groove, and the limiting groove fits with the limiting ball.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The setting of the first return spring can ensure the consistency of the mold operating parts, and can accurately restore to the same position and state each time the operation is performed, thereby improving the accuracy and quality of riveting. At the same time, it can ensure that the mold is restored to a stable and safe position after each operation, avoiding damage to the mold or workpiece due to operating errors. The adjustment base plate is rotated by an external hexagonal wrench, and the rotation of the adjustment base plate drives the threaded rod to rotate, and the rotation of the threaded rod causes the lifting member to move. Under the limitation of the slide groove and the slider, the lifting member can only move in the direction of the slide groove. The movement of the lifting member drives the movement of the first return spring, and the movement of the first return spring drives the movement of the movable block, and the movement of the movable block drives the movement of the floating center needle, thereby adjusting the height of the floating center needle, so that the mold can adapt to various sizes and types of rivets. The operator can quickly adjust the mold according to specific needs without having to replace different molds or perform complicated adjustment steps;

[0019] 2. When installing the floating cylinder, you can first move the fixing piece, and the movement of the fixing piece drives the pressure block to move. The pressure block moves and compresses the second return spring, so that the second return spring is in a compressed state, and then directly insert the floating cylinder. After the floating cylinder is inserted into the sleeve rod, release the fixing piece, and the second return spring recovers to its initial state after losing pressure. One end of the second return spring moves to drive the pressure block to move, and the pressure block moves to abut against the limiting ball, so that the limiting ball sinks into the limiting groove, thereby completing the limiting of the floating cylinder, that is, completing the connection between the connecting base and the floating cylinder. The installation operation of the floating cylinder is simple and convenient, and the floating cylinder is easy to install and disassemble, thereby ensuring processing efficiency.
