Description

Technical Field

[0001] The utility model relates to the technical field of bending dies, and more specifically, to a bending die with adjustable angle. Background Technique

[0002] A bending die generally refers to a die for a bending machine. The die for a bending machine is a tool used by the bending machine to form and process sheet materials. Such a tool is composed of various parts, and different dies are composed of different parts. It mainly realizes the processing of the outer shape of an article by changing the physical state of the formed material.

[0003] The prior art patent document with the publication number of CN209577901U provides a bending die with adjustable bending angle, which includes an upper die assembly and a lower die assembly. The upper die assembly includes an upper pressing plate and a positioning pressing plate. A positioning pressing plate is arranged below the upper pressing plate, and a positioning pressing rod is arranged in the middle of the positioning pressing plate. The positioning pressing rod penetrates upward through the upper pressing plate. The lower die assembly includes a lower die base. A hollow-shaped fixing plate is arranged directly above the lower die base. A lower die frame is arranged inside the fixing plate. Multiple groups of small holes are arranged on the left and right sides of the lower die frame. A bending punch is installed in any group of small holes parallel to the left and right sides of the lower die frame. Baffles are arranged on the left and right sides above the lower die base. Guide posts are respectively arranged at the four feet below the lower die frame. Springs are sleeved outside the guide posts, and a guide plate is arranged below the guide posts. However, the overall operation performance of this device and most such bending dies on the market is relatively single, and it cannot better meet the operation requirements during the workshop processing of bending dies. Although in the prior art CN209577901U, the purpose of adjusting the angle of the bent workpiece can be achieved by adjusting the height of the bending punch, and at the same time, it is realized that multiple models of products can be bent using one bending die, saving production costs. However, during the adjustment of the die, the angle adjustment is aimed at the angle that fits its own height. When the orientation angle of the die punch changes, the die itself cannot perform corresponding angle adjustment. Therefore, compensation is required to increase the operation performance of the die. In view of this, we propose a bending die with adjustable angle. Summary of the Utility Model

[0021] The present utility model provides a technical solution:

[0022] As Figure 1 and Figure 3 shown, the angle-adjustable bending die includes a support structure 1. A support plate 8 is fixedly installed at the top of the support structure 1. A support base 5 is rotatably installed on the front surface of the support plate 8. Fastening screws for cooperative use are arranged on the support structure 1, and the fastening screws are distributed at the four corners of the support structure 1.

[0023] In this embodiment, during the preparation for operation, the operator installs and fixes the bending die through the fastening screws on the support structure 1 so that it can be located on the corresponding processing equipment, and conducts targeted adjustment through the working structures of the support plate 8 and the support base 5.

[0024] In some technical solutions, as Figure 1 and Figure 2As shown, a transmission gear 2 is rotatably installed on the support plate 8 below the support base 5, an adjustment structure 7 is fixedly installed on the rear side of the top of the support structure 1, and the adjustment structure 7 is rotatably connected to the transmission gear 2. The adjustment structure 7 includes a rotating knob 701 and a mounting seat 702. The mounting seat 702 is attached to the support structure 1 on the rear side of the support plate 8, and a rotating knob 701 connected to the transmission gear 2 is installed through the mounting seat 702.

[0025] In this embodiment, during the operation, the personnel can make targeted adjustments according to the actual orientation of the processing, and complete it through the adjustment structure 7. The personnel rotate the rotating knob 701 on the mounting seat 702, and then the rotating knob 701 will drive the transmission gear 2 on the support plate 8 to rotate, and the rotation of the transmission gear 2 will simultaneously drive the driven structure 3 on the support base 5 to follow the rotation, and then realize the adjustment rotation of the support base 5 to change its operating direction. Through the mutual cooperation of the adjustment structure 7 on the support structure 1 and the transmission gear 2, the device can switch the angle adjustment through the gear meshing transmission, so that the operating direction of the mold can be switched, and the gear adjustment method is more flexible than the traditional fixed-point adjustment, meeting the real-time angle adjustment needs.

[0026] In some technical solutions, such as Figure 1 and Figure 4 As shown, the support base 5 is connected to the transmission gear 2 and the support plate 8 through the driven structure 3. The driven structure 3 includes a shaft positioning cap 301, a rack 302, and a hollow shaft 303. The hollow shaft 303 is rotatably installed on the support plate 8, and the hollow shaft 303 is rotatably connected to the support base 5. The support base 5 is provided with a shaft positioning cap 301 that is docked with the hollow shaft 303. The shaft positioning cap 301 and the hollow shaft 303 are docked with each other through a threaded structure. The bottom of the support base 5 is fixedly installed with a rack 302 that cooperates with the transmission gear 2. The back of the support base 5 is fixedly installed with a load-bearing sliding structure 4 that is slidably connected to the support plate 8. The load-bearing sliding structure 4 includes a built-in guide groove 401 and a connecting guide block 402. The front of the support plate 8 is provided with a built-in guide groove 401, and a connecting guide block 402 that is slidably connected to the support base 5 is placed in the built-in guide groove 401.

[0027] In this embodiment, during operation, the rotation of the transmission gear 2 will drive the driven structure 3 on the support base 5 to rotate accordingly, and then the adjustment rotation of the support base 5 is realized to change its operation orientation. The transmission gear 2 drives the rack 302 to push the support base 5. Under the action of the transmission force, the support base 5 rotates. The support base 5 performs fixed-point rotation through the hollow rotating shaft 303. At the same time of rotation, the load-bearing sliding structure 4 bears the force on the support base 5. The support base 5 performs fixed-point rotation through the hollow rotating shaft 303. The connecting guide block 402 on the back of the support base 5 will slide accordingly in the built-in guide groove 401. It should be noted that the built-in guide groove 401 is an arc-shaped structure, which can fit the swinging operation of the support base 5, and while following the rotation, it also realizes the bearing force on the whole support base 5. Through the load-bearing sliding structure 4 on the support base 5, the mold can rotate in cooperation and at the same time play an auxiliary bearing effect, avoiding the reduction of the mold bearing performance caused by simply adjusting the angle. While performing auxiliary cooperative guiding adjustment, the mold can be weighed, and the stability of the mold during impact processing can be increased.

[0028] In some technical solutions, a die core 6 is fixedly installed on the top of the support base 5, and a die head that cooperates with each other is arranged on the top of the die core 6.

[0029] In this embodiment, during operation, the die core 6 is fixedly installed on the support base 5, and then the material is placed on the die core 6, and the impact bending forming operation is carried out through the die head.
