Description

Technical Field

[0001] This utility model relates to the field of stretching die technology, and more specifically to a stretching die for high-efficiency production. Background Technology

[0002] Die stretching is a cold stamping process. Its main purpose is to change the shape and size of a flat blank or open hollow part by applying tension in order to manufacture the required hollow parts. Die stretching has a very common application in production, such as the manufacture of thin-walled containers. Through the stretching process, metal sheets can be processed into open hollow parts, such as the body of a pressure cooker.

[0003] During the stretching process, it is necessary to keep the material and the extrusion contact surface of the mold lubricated to reduce friction, improve the service life of the mold and the quality of the product. The mold is mainly divided into a hollow mold and a raised mold. In the existing technology, the surface of the mold is mainly coated manually with a brush dipped in lubricant. This method is not only inefficient, but also easy to contaminate the workers' limbs during the coating process. In addition, it poses a safety hazard because the workers' limbs are inserted into the mold to coat the mold. Utility Model Content

The rotating component includes a rotating rod movably mounted on the top of the mounting plate, a mounting block fixedly connected to the top of the rotating rod, a lubricating sponge block fixedly connected to the top of the mounting block, and a driven gear fixedly mounted on the outer side of the rotating rod. The rotating component also includes a rotary motor fixedly connected to the bottom of the mounting plate, with a driving gear fixedly connected to the output shaft of the rotary motor. The driving gear and the driven gear mesh with each other. A hollow cavity is formed on the inner side of the mounting plate, and both the driven gear and the driving gear are located inside the hollow cavity.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model comprises a translation component, a lifting component, and a rotation component. The piston rod of the translation component pushes the translation plate horizontally to the left, thereby moving the rotation rod to a position directly below the upper mold. Then, the lifting motor and the rotation motor are started simultaneously. The meshing of the driving gear and the driven gear drives the rotation rod to rotate. The lifting motor drives the lead screw to rotate. Under the thrust of the lead screw thread, the mounting plate moves vertically upward along the outside of the lead screw, thereby allowing the lubricating sponge block to extend into the inside of the upper mold and maintain its rotation, thus achieving the function of lubricating the inside of the upper mold. This reduces the labor intensity of manual lubrication, avoids the contamination of workers' limbs by lubricating oil, and reduces safety hazards.

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 5This utility model provides a high-efficiency stretching die, including a workbench 1. Support legs 101 are fixedly connected to the four corners of the bottom of the workbench 1. A lower die 102 is fixedly connected to the center of the top of the workbench 1. A support assembly 103 is installed on the top of the workbench 1. A translation assembly 2 is installed on the right side of the top of the workbench 1. A lifting assembly 3 is installed on the left side of the translation assembly 2. A rotating assembly 4 is installed on the top of the lifting assembly 3. The lifting assembly 3 includes a second fixing plate 301. A lifting motor 302 is fixedly connected to the bottom of the second fixing plate 301.

A mounting plate is threaded onto the outer side of the lead screw 303. 304, the rotating assembly 4 includes a rotating rod 401 movably sleeved on the top of the mounting plate 304, a mounting block 402 fixedly connected to the top of the rotating rod 401, a lubricating sponge block 403 fixedly connected to the top of the mounting block 402, a driven gear 404 fixedly sleeved on the outer side of the rotating rod 401, the rotating assembly 4 also includes a rotating motor 405 fixedly connected to the bottom of the mounting plate 304, a driving gear 406 fixedly connected to the output shaft of the rotating motor 405, the driving gear 406 and the driven gear 404 meshing with each other, a hollow cavity 341 is opened on the inner side of the mounting plate 304, and both the driven gear 404 and the driving gear 406 are located inside the hollow cavity 341.

[0023] In this embodiment, when applying lubricating oil to the inner side of the upper mold 108, the piston rod of the translation component 2 pushes the translation plate 203 to move horizontally to the left, thereby moving the rotating rod 401 to a position directly below the upper mold 108. Then, the lifting motor 302 and the rotating motor 405 are started simultaneously. Through the meshing of the driving gear 406 and the driven gear 404, the rotating rod 401 is driven to rotate. The lifting motor 302 drives the lead screw 303 to rotate. Under the thread thrust of the lead screw 303, the mounting plate 304 moves vertically upward along the outer side of the lead screw 303, thereby allowing the lubricating sponge block 403 to extend into the inner side of the upper mold 108 and maintain a rotating state, thus achieving the function of lubricating the inside of the upper mold 108. This reduces the labor intensity of manual lubrication, avoids the situation where lubricating oil contaminates the workers' limbs, and reduces safety hazards.

[0024] Among them, support frames 104 are fixedly connected to the top of the workbench 1 on all four sides. A top plate 105 is fixedly connected to the top of the support frame 104. A hydraulic cylinder 106 is fixedly connected to the top of the top plate 105. A lifting plate 107 is fixedly connected to the bottom of the hydraulic rod of the hydraulic cylinder 106. An upper mold 108 is fixedly connected to the bottom of the lifting plate 107.

[0025] The upper mold 108 and the lower mold 102 are located in the same vertical direction. The top of the lifting plate 107 is provided with a limit rod so that the hydraulic cylinder 106 controls the lifting plate 107 to remain stable when it is raised and lowered, so that the upper mold 108 and the lower mold 102 can stably stretch and form the material.

[0026] The support assembly 103 includes a cylindrical rod 131 that is movably sleeved on the top of the workbench 1. A support plate 132 is fixedly connected to the top of the cylindrical rod 131. A spring 133 is movably sleeved on the outer side of the cylindrical rod 131. A cylindrical hole 134 is opened in the middle of the top of the support plate 132. The cylindrical hole 134 is adapted to the lower mold 102.

[0027] Spring 133 exerts an upward thrust on support plate 132, and the top of lower mold 102 is located inside cylindrical hole 134, so that plate can be placed stably on top of support plate 132.

[0028] The translation component 2 includes a first fixed plate 201 fixedly connected to the top of the workbench 1. A cylinder 202 is fixedly connected to the right side of the first fixed plate 201. A translation plate 203 is fixedly connected to the left side of the piston rod of the cylinder 202. The right side of the second fixed plate 301 is fixedly connected to the left side of the translation plate 203. A positioning rod 204 is fixedly connected to the right side of the translation plate 203. The translation plate 203 is movably sleeved with the first fixed plate 201.

[0029] The cylinder 202 can drive the lifting component 3 and the rotating component 4 to move horizontally. When the piston rod of the cylinder 202 is fully extended, the lubricating sponge block 403 is located directly below the upper mold 108.

[0030] The top of the translation plate 203 is fixedly connected to a support plate 205, and the top of the support plate 205 is fixedly connected to a fixing block 206. The fixing block 206 is rotatably connected to the top of the lead screw 303. A roller 305 is movably sleeved on the right side of the mounting plate 304, and the roller 305 is in contact with the surface of the translation plate 203.

[0031] The right side of the mounting plate 304 is attached to the left side of the translation plate 203, and the left surface of the bracket plate 205 is aligned with the left surface of the translation plate 203, which can play a positioning role for the mounting plate 304. Thus, when the lead screw 303 rotates, the mounting plate 304 can only move up and down, and will not rotate.

[0032] Working principle and usage process of this utility model:

[0033] When lubricating oil needs to be applied to the inside of the upper mold 108, the piston rod of the translation component 2 pushes the translation plate 203 to move horizontally to the left, thereby moving the rotating rod 401 to a position directly below the upper mold 108. Then, the lifting motor 302 and the rotating motor 405 are started simultaneously. Through the meshing of the driving gear 406 and the driven gear 404, the rotating rod 401 is driven to rotate. The lifting motor 302 drives the lead screw 303 to rotate. Under the thread thrust of the lead screw 303, the mounting plate 304 moves vertically upward along the outside of the lead screw 303, thereby allowing the lubricating sponge block 403 to extend into the inside of the upper mold 108 and maintain a rotating state, thus achieving the function of lubricating the inside of the upper mold 108. This reduces the labor intensity of manual lubrication, avoids the situation of lubricating oil contaminating the workers' limbs, and reduces safety hazards.
