Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal flattening devices, and in particular to a sheet metal flattening device for sheet metal processing. Background Technology

[0002] In the field of sheet metal processing, the flatness of sheet metal parts directly affects the subsequent assembly accuracy and product quality. Therefore, flattening sheet metal parts is an important processing step. Currently, most common sheet metal flattening devices achieve flattening through mechanical pressure.

[0003] In the prior art, flattening devices typically include a processing table, a support, a drive element, and a pressure plate. The drive element moves the pressure plate downward, and the support structure on the processing table applies pressure to the sheet metal to eliminate deformation of the sheet metal.

[0004] However, existing flattening devices still have certain limitations in practical applications: some sheet metal sheets have poor plasticity at room temperature and are prone to springback after being compressed, requiring multiple or higher pressure applications, which not only reduces processing efficiency and increases energy consumption but also easily damages the sheet metal. Therefore, a sheet metal flattening device for sheet metal processing is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of some sheet metal sheets having poor plasticity at room temperature and being prone to springback after being pressed, which requires multiple or greater pressure applications, reducing processing efficiency, increasing energy consumption, and easily damaging the sheet metal sheets. Therefore, this invention proposes a sheet metal flattening device for sheet metal processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sheet metal flattening device for sheet metal processing, comprising a processing table, a bracket fixedly mounted on the surface of the processing table, an electric push rod fixedly mounted on the surface of the bracket, a pressure plate fixedly mounted on the output end of the electric push rod, a fixed plate fixedly mounted on the processing table relative to the pressure plate, a sheet metal sheet slidably connected to the upper surface of the fixed plate, a fixed frame fixedly mounted on the upper surface of the processing table, a sliding plate slidably connected to the inner wall of the fixed frame, an upper heat insulation plate fixedly mounted on the surface of the sliding plate, and an electric heating plate fixedly mounted on the surface of the upper heat insulation plate.

[0007] The effect achieved by the above components is as follows: by setting a fixed frame, a sliding plate, an upper heat insulation plate and an electric heating plate, the electric heating plate can be preheated before pressure is applied to the sheet metal, so as to avoid the sheet metal from springing back after pressure is applied and effectively eliminate the deformation of the sheet metal.

[0008] Preferably, a rotating shaft is rotatably connected to the surface of the processing table, a gear is fixedly mounted on the circumferential surface of the rotating shaft, a rack that meshes with the gear is fixedly mounted on the surface of the sliding plate, a servo motor is fixedly mounted on the surface of the processing table, the output end of the servo motor is fixedly connected to the rotating shaft, and a lower insulation plate is fixedly mounted on the surface of the processing table, the size of the lower insulation plate being adapted to the size of the upper insulation plate.

[0009] The effect achieved by the above components is that the upper and lower insulation plates work together to cover the sheet metal, thereby slowing down the heat loss rate of the heating plate and making it easier to use the heating plate next time.

[0010] Preferably, a baffle is fixedly mounted on the surface of the skateboard, and the baffle is slidably connected to the fixed frame.

[0011] The effect achieved by the above components is that during the movement of the skateboard, the baffle will slide along the surface of the fixed frame, and the baffle and the fixed frame can restrict the movement path of the skateboard.

[0012] Preferably, a buffer block is fixedly fitted onto the inner wall of the fixed frame.

[0013] The effect achieved by the above components is that when the skateboard comes into contact with the buffer block, the buffer block can cushion the skateboard and prevent the skateboard from hitting the fixed frame quickly.

[0014] Preferably, a push-pull rod is slidably connected to the surface of the processing table, and a push plate is fixedly mounted on the surface of the push-pull rod.

[0015] The effect achieved by the above components is as follows: after the flattening operation is completed, the push-pull rod is moved, and the processed sheet metal is pushed off the fixed plate through the push plate.

[0016] Preferably, the processing table is rotatably connected to a plurality of rotating rods relative to the position of the fixed plate.

[0017] The effect achieved by the above components is that the rotating rod can guide the sheet metal.

[0018] Preferably, the processing table is fixedly equipped with a placement frame relative to the position of the rotating rod, and a collection box is slidably connected to the surface of the placement frame.

[0019] The effect achieved by the above components is that the collection box will collect sheet metal sheets.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a fixed frame, a sliding plate, an upper heat insulation plate, and an electric heating plate, the electric heating plate can be preheated before applying pressure to the sheet metal, thus preventing the sheet metal from springing back after pressure is applied and effectively eliminating sheet metal deformation.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-4As shown, this utility model provides a sheet metal flattening device for sheet metal processing, including a processing table 1, a support 2 fixedly mounted on the surface of the processing table 1, an electric push rod 3 fixedly mounted on the surface of the support 2, a pressure plate 4 fixedly mounted on the output end of the electric push rod 3, a fixed plate 5 fixedly mounted on the processing table 1 relative to the pressure plate 4, a sheet metal sheet 6 slidably connected to the upper surface of the fixed plate 5, a fixed frame 7 fixedly mounted on the upper surface of the processing table 1, a sliding plate 8 slidably connected to the inner wall of the fixed frame 7, an upper heat insulation plate 9 fixedly mounted on the surface of the sliding plate 8, an electric heating plate 10 fixedly mounted on the surface of the upper heat insulation plate 9, a rotating shaft 12 rotatably connected to the surface of the processing table 1, a gear 14 fixedly mounted on the circumferential surface of the rotating shaft 12, a rack 15 meshing with the gear 14 fixedly mounted on the surface of the sliding plate 8, and a servo motor fixedly mounted on the surface of the processing table 1. The output end of the servo motor 13 is fixedly connected to the rotating shaft 12. A lower heat insulation plate 11 is fixedly mounted on the surface of the processing table 1. The size of the lower heat insulation plate 11 is adapted to the size of the upper heat insulation plate 9. The upper heat insulation plate 9 and the lower heat insulation plate 11 cooperate to cover the sheet metal plate 6, thereby slowing down the heat loss rate of the heating plate 10 and facilitating the next use of the heating plate 10. A baffle 16 is fixedly mounted on the surface of the slide plate 8. The baffle 16 is slidably connected to the fixed frame 7. During the movement of the slide plate 8, the baffle 16 will slide along the surface of the fixed frame 7. The baffle 16 and the fixed frame 7 cooperate to restrict the movement path of the slide plate 8. A buffer block 17 is fixedly mounted on the inner wall of the fixed frame 7. When the slide plate 8 contacts the buffer block 17, the buffer block 17 can buffer the slide plate 8 and prevent the slide plate 8 from hitting the fixed frame 7 quickly.

[0026] A push-pull rod 18 is slidably connected to the surface of the processing table 1. A push plate 19 is fixedly mounted on the surface of the push-pull rod 18. After the flattening operation is completed, the push-pull rod 18 is moved, and the processed sheet metal 6 is pushed off the fixed plate 5 through the push plate 19. Several rotating rods 20 are rotatably connected to the processing table 1 relative to the position of the fixed plate 5. The rotating rods 20 can guide the sheet metal 6. A placement rack 21 is fixedly mounted to the processing table 1 relative to the position of the rotating rods 20. A collection box 22 is slidably connected to the surface of the placement rack 21. The collection box 22 will collect the sheet metal 6.

[0027] The overall working principle is as follows: the sheet metal 6 to be processed is placed on the fixed plate 5, the servo motor 13 is started to drive the rotating shaft 12 to rotate, and through the meshing transmission of the gear 14 and the rack 15, the sliding plate 8 is driven to slide along the inner wall of the fixed frame 7, so that the upper heat insulation plate 9 and the electric heating plate 10 move towards the sheet metal 6 until the electric heating plate 10 moves above the sheet metal 6. At this time, the electric heating plate 10 is energized to generate heat, which heats the sheet metal 6 and improves the plasticity of the sheet metal 6 by increasing the temperature.

[0028] Once the sheet metal plate 6 reaches a suitable temperature, the servo motor 13 reverses its rotation, causing the heating plate 10 to move away from above the sheet metal plate 6. At this time, the upper insulation plate 9 and the lower insulation plate 11 work together to cover the sheet metal plate 6, thereby slowing down the heat loss rate of the heating plate 10 and facilitating its next use. Then, the electric push rod 3 drives the pressure plate 4 to move downward, working with the fixed plate 5 to apply pressure to the sheet metal plate 6. Through the combined action of heat and mechanical force, the sheet metal plate 6 is prevented from rebounding after being pressed, effectively eliminating deformation of the sheet metal plate 6. During the movement of the slide plate 8, the baffle 16 slides along the surface of the fixed frame 7. The baffle 16 and the fixed frame 7 work together to restrict the movement path of the slide plate 8. When the slide plate 8 contacts the buffer block 17, the buffer block 17 can buffer the slide plate 8, preventing the slide plate 8 from rapidly impacting the fixed frame 7.

[0029] After the flattening operation is completed, the push-pull rod 18 is moved, and the processed sheet metal 6 is pushed to the rotating rod 20 through the push plate 19. The sheet metal 6 slides along the rotating rod 20 and falls into the collection box 22 on the placement rack 21. The collection box 22 will collect the sheet metal 6 for easy transfer later. The rotating rod 20 can guide the sheet metal 6.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
