Description

Technical Field

[0001] This utility model relates to the field of bending forming technology, specifically a bending forming device for relay production. Background Technology

[0002] Bending and forming equipment is a specialized device used for bending, forming, and folding materials such as metal sheets and strips. In the field of relay manufacturing, this device is mainly used to process components that require precise bending, such as relay housings, lead clamps, terminal blocks, spring sheets, and internal contact structures.

[0003] In existing technologies, manual bending is quite cumbersome, requires a lot of physical exertion from workers, and can easily increase their physical exhaustion.

[0004] To overcome the above shortcomings, a Chinese patent (publication number CN111640619A) discloses a high-efficiency bending machine for relay terminals. This machine addresses the problem that most terminal bending processes are manually operated, resulting in high labor costs, low efficiency, high defect rates, and high rework rates. The machine includes a workbench with two parallel side plates fixed to its top. Two parallel loading devices are fixed to the top of the two side plates. A storage slot is provided on the top of the sidewalls of the two loading devices, close to each other. A relay frame with terminals vertically downwards is engaged within the storage slot. A horizontally positioned limiting plate is slidably connected to one side of the relay frame. The machine has a simple structure and achieves bending of terminals on the relay frame in both the horizontal and vertical directions. It is highly efficient and precise, eliminates the need for manual bending, improves bending efficiency and product qualification rate, and has a wide range of applications.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, when the internal components of the relay need to be bent, the left and right ends of the plate-shaped device are prone to upward bending forces, resulting in poor stability of the device during bending. Utility Model Content

[0006] The purpose of this invention is to provide a bending and forming device for relay production, in order to solve the problem mentioned in the background art that when the internal components of a relay need to be bent, the left and right ends of the plate-shaped device are prone to upward bending force, resulting in poor stability of the device during bending.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bending forming device for relay production, comprising a machine body and a lifting block disposed inside the machine body, a hydraulic rod being installed through the middle of the machine body, a lifting plate being fixedly installed at the output end of the hydraulic rod, a bending component being fixedly installed at the bottom of the lifting plate, a component plate being placed on the upper end of the lifting block, abutting and pressing mechanisms being installed on the lower ends of the left and right sides of the lifting plate, and a convenient placement mechanism being disposed at the bottom of the machine body.

[0008] Furthermore, the upper end of the lifting block is provided with a triangular opening, and the opening of the lifting block corresponds to the bending member.

[0009] Furthermore, the pressing mechanism is equipped with a positioning rod, and the left and right ends of the positioning rod are fixedly installed at the lower end of the lifting plate. A movable block is sleeved on the surface of the positioning rod, and an adjustment plate is rotatably installed at the lower end of the movable block.

[0010] Furthermore, a pressure plate is rotatably mounted on the bottom of the adjusting plate, and a pressure roller is rotatably mounted inside the pressure plate, and the pressure roller corresponds to the upper end device plate of the lifting block.

[0011] Furthermore, dampers are installed through the left and right ends of the lifting plate, and the lower end of the output end of the damper is fixedly installed on the upper end of the pressure plate.

[0012] Furthermore, the machine body is equipped with a moving platform inside, and the upper end of the moving platform is installed at the lower end of the lifting block. The moving platform is in the shape of a groove. An electric push rod is fixedly installed at the lower end of the machine body, and the output end of the electric push rod is fixedly connected to the rear end of the moving platform.

[0013] Furthermore, a baffle is fixedly installed on the upper end of the machine body, and abutment plates are fixedly installed on the left and right sides of the rear end of the mobile platform, with the abutment plates corresponding to the baffles.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The bottom of the movable block is connected to the adjustment plate, which can push the pressure plate. The pressure plate applies pressure to the left and right sides of the device board through the pressure roller. With the damper setting, the reciprocating vibration of the return spring can be avoided, which further improves stability. It can stably press the left and right sides of the device board. When the device board is bent into shape, the left and right sides of the device board shrink along the roller, which further improves the stability of bending and forming.

[0016] Furthermore, the activation of the hydraulic rod can drive the lifting plate to adjust its height. When the lifting plate is adjusted in height, it can drive the bending component to move, so that the lower end of the bending component pushes the device plate to bend inside the groove of the support block, thus enabling stable bending and shaping.

[0017] 2. By pre-activating the electric push rod, the activation of the electric push rod can drive the set-up moving platform. The movement of the moving platform can drive the upper lifting block to move, so that the lifting block moves to the front of the machine body, making it more convenient for the staff to place it.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1 and Figure 3 - Figure 6The technical solution shown is a bending and forming device for relay production. To solve the problem that the left and right sides of the device board tend to warp when bending, the device board is provided with: a machine body 1 and a lifting block 2 installed inside the machine body 1. A hydraulic rod 3 is installed through the middle of the machine body 1, and a lifting plate 4 is fixedly installed at the output end of the hydraulic rod 3. A bending component 5 is fixedly installed at the bottom of the lifting plate 4. The device board is placed on the upper end of the lifting block 2. A pressing mechanism is installed on the lower ends of the left and right sides of the lifting plate 4. A triangular opening is provided at the upper end of the lifting block 2, and the opening of the lifting block 2 corresponds to the bending component 5. The pressing mechanism is provided with a positioning rod 6, and the left and right ends of the positioning rod 6 are fixedly installed at the lower end of the lifting plate 4. A movable block 7 is sleeved on the surface of the positioning rod 6. An adjusting plate 8 is rotatably installed at the lower end of the movable block 7. A pressure plate 9 is rotatably installed at the bottom of the adjusting plate 8. A pressure roller 10 is rotatably installed inside the pressure plate 9, and the pressure roller 10 corresponds to the device board at the upper end of the lifting block 2.

[0027] When using this relay production bending forming device, the relay production component board is placed on the lifting block 2. After placement, the hydraulic rod 3 on the machine body 1 is activated. The activation of the hydraulic rod 3 can push the lifting plate 4 to adjust its height. When the height of the lifting plate 4 is adjusted, it can drive the bending component 5 to move, so that the lower end of the bending component 5 pushes the component board into the groove inside the lifting block 2 to bend, which can stably perform bending forming. At the same time, when the lifting plate 4 descends, the pressure plate 9 at the bottom of the lifting plate 4 contacts the component board first, and the internal rotation of the pressure plate 9... A pressure roller 10 is mounted on the device, and a movable block 7 is sleeved on the surface of the positioning rod 6. The movable block 7 can be pushed by the reset spring 11. The bottom of the movable block 7 is rotatably connected to the adjustment plate 8, which can push the pressure plate 9. The pressure plate 9 applies pressure to the left and right sides of the device board through the pressure roller 10. With the damper 12, the reciprocating vibration of the reset spring 11 can be avoided, further improving stability. The device board can be stably pressed together on the left and right sides. When the device board is bent and formed, the left and right sides of the device board shrink along the roller, further improving the stability of the bending and forming.

[0028] Example 2: Figure 1 - Figure 4The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of inconvenient placement of the device board: a convenient placement mechanism is provided at the bottom of the body 1; dampers 12 are installed through the left and right ends of the lifting plate 4, and the lower end of the output end of the damper 12 is fixedly installed on the upper end of the pressure plate 9; a moving platform 14 is provided inside the body 1, and the upper end of the moving platform 14 is installed on the lower end of the lifting block 2, and the moving platform 14 is in the shape of a groove; an electric push rod 13 is fixedly installed at the lower end of the body 1, and the output end of the electric push rod 13 is fixedly connected to the rear end of the moving platform 14; a baffle 16 is fixedly installed at the upper end of the body 1; and abutment plates 15 are fixedly installed on the left and right sides of the rear end of the moving platform 14, and the abutment plates 15 and the baffle 16 are correspondingly arranged.

[0029] When placing the relay production component board, the electric push rod 13 is activated in advance. The activation of the electric push rod 13 can drive the mounted moving platform 14. The movement of the moving platform 14 can drive the upper lifting block 2 to move, so that the lifting block 2 moves towards the front end of the machine body 1, making it more convenient for the staff to place. At the same time, with the setting of the abutment plate 15, the moving platform 14 is blocked by the baffle 16 after moving, so the movement is stable and limited.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
