Description

Technical Field

[0001] The utility model relates to the technical field of gold jewelry processing, in particular to a bending mechanism of a gold jewelry processing and forming machine. Background Technique

[0002] Gold is a precious metal and one of the earliest metals discovered and exploited by humans. It is an important raw material for making jewelry and coins and an important reserve material for the country. It is not only regarded as a symbol of beauty and wealth, but also benefits human life with its unique value. When processing gold jewelry, a bending machine is needed for bending.

[0003] According to the Chinese patent publication number: CN220574430U, a bending mechanism of a gold jewelry processing and forming machine is disclosed. Through the mutual cooperation of a turntable, a threaded rod, a threaded groove, a clamping block, a clamping groove, a motor, a rotating rod, a gear, a rack, a hydraulic rod and a bending roller, when different bending effects are required, the turntable is rotated. The turntable drives the threaded rod to rotate. The threaded rod rotates out of the threaded groove, and then the bending column is replaced through the clamping block and the clamping groove. At the same time, the motor is started. The motor drives the rotating rod to rotate. The rotating rod drives the gear to rotate. The gear drives the rack to move left and right and drives the hydraulic rod and the bending roller to move left and right to adjust the bending distance according to the newly replaced bending column, so as to adjust the bending effect. This achieves the purpose of adjusting different bending effects and meets the usage requirements of people.

[0004] However, in this technical solution, the two bending rollers are driven by two separate motors and separate hydraulic rods. When adjusting the distance between the two bending rollers, it is easy to cause the moving distances of the two bending rollers to be inconsistent, resulting in deviation of the bending position. Moreover, it is also easy to cause the acting forces of the two bending rollers on both ends of the gold jewelry to be different, thus affecting the bending quality. For this reason, we propose a bending mechanism of a gold jewelry processing and forming machine. Content of the Utility Model

A spring is fixedly installed between one end of the slide rod and the inner wall of the rod groove. A connecting block is fixedly installed on the outer wall of the slide rod. A limiting groove is formed through the inner wall of the rod groove, and the connecting block movably penetrates through the limiting groove. A fixed frame is fixedly installed inside the fixed box.

Two chute grooves are formed on the pressing plate. The first connecting rod and the second connecting rod respectively movably penetrate through the two chute grooves. The other end of the slide rod is fixedly installed with a bending roller.

[0008] Preferably, the first connecting rod and the second connecting rod are respectively adapted to the two chute grooves, and the connecting block is adapted to the limiting groove.

[0014] (1) The bending mechanism of the gold jewelry processing and forming machine can make two bending rollers simultaneously press the gold jewelry forward through the setting of the bending mechanism, so that both ends of the gold jewelry are subjected to the same force, ensuring the bending effect of the gold jewelry. Moreover, when adjusting the distance between the two bending rollers, the moving distances of the two bending rollers are also the same, thereby ensuring the accuracy of the bending position of the gold jewelry.

[0025] The preferred embodiment of the bending mechanism of the gold jewelry processing and forming machine provided by the present utility model is as Figures 1 to 5 shown: A bending mechanism of a gold jewelry processing and forming machine, including a bottom plate 1, and a bending mechanism 4 is arranged at the top end of the bottom plate 1;

[0026] The bending mechanism 4 includes a fixed box 401, a first connecting rod 403, and a second connecting rod 404. The fixed box 401 is fixedly installed at the top end of the bottom plate 1. A bidirectional screw rod 402 penetrates through the front of the fixed box 401, and the bidirectional screw rod 402 is rotatably connected to the fixed box 401 through a bearing. A motor 405 is fixedly installed on the front of the fixed box 401. The bidirectional screw rod 402 is fixedly installed at the output end of the motor 405. One end of the first connecting rod 403 and one end of the second connecting rod 404 are both threadedly sleeved on the outer wall of the bidirectional screw rod 402.

A limiting groove 413 is penetrated through the inner wall of the rod groove. The connecting block 414 movably penetrates through the limiting groove 413. A fixed frame 406 is fixedly installed inside the fixed box 401. A hydraulic cylinder 407 is fixedly installed on the outer wall of the fixed frame 406. One end of the piston rod of the hydraulic cylinder 407 is fixedly installed with a pressing plate 412. Two sliding grooves 408 are opened on the pressing plate 412.
