Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a continuous die stamping device for chassis panels. Background Technology

[0002] The progressive die stamping device for chassis panels is a stamping system composed of multi-station progressive dies. Its core structure includes an upper die and a lower die. The material is continuously fed in and completes multiple processes such as punching, bending, and forming in a single stroke of the press, ultimately forming a complete part.

[0003] A continuous die stamping device for chassis panels, application number CN202211452399.8, includes a frame with a sliding block that moves vertically and horizontally on the frame. An upper die is mounted on the sliding block. Lower dies one, two, and three are sequentially mounted on the frame, all located below the upper die. Lower die one cooperates with the upper die to stamp several mounting grooves on the sheet metal. Lower die two cooperates with the upper die to stamp the groove depth and cutting lines of the mounting grooves on the sheet metal. Lower die three cooperates with the upper die to stamp several bolt holes and cut the sheet metal. A drive unit is provided on the frame to drive the sliding block to move. The three processes of processing the mounting groove shape, groove depth, and bolt holes are performed simultaneously. The operator only needs to place the sheet metal in and remove the processed sheet metal, simplifying the operation and improving the processing efficiency of chassis panels. However, after placing the chassis panel to be processed on the lower die, there is a risk of lateral movement of the material during stamping and conveying, which may affect processing accuracy. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a continuous die stamping device for chassis panels.

[0005] An embodiment of this utility model provides a continuous die stamping device for chassis panels, comprising:

[0006] The base has a support frame and a vertical frame fixedly connected to its upper surface. A cylinder is fixedly installed on the upper surface of the vertical frame, and a lower continuous mold is installed on the cylinder. An upper continuous mold is installed on the support frame. A limit assembly and a collection assembly are installed on the support frame. The limit assembly includes two sliding grooves on the support frame. Two connecting frames are slidably connected between the two sliding grooves. A bidirectional screw is rotatably connected to the inner wall of one of the sliding grooves. The bidirectional screw is threaded through the two connecting frames. A first motor is fixedly installed on the side wall of the support frame. The rotating end of the first motor is fixedly connected to the bidirectional screw. Belt conveyor assemblies are installed on both connecting frames, and the two belt conveyor assemblies are symmetrically arranged.

[0007] Furthermore, the belt conveyor assembly includes two drive rollers rotatably connected to the connecting frame, which are driven by a transmission belt.

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a continuous die stamping device for chassis panels, comprising:

[0022] The base 1 has anti-slip textures on its lower end surface to improve the stability of the device. The upper end surface of the base 1 is fixedly connected to the support frame 2 and the upright frame 3. The upper end surface of the upright frame 3 is fixedly installed with the cylinder 4. The lower continuous mold 5 is installed on the cylinder 4. The upper continuous mold 6 is installed on the support frame 2. The telescopic end of the cylinder 4 is fixedly connected to the fixing plate. Multiple second springs 19 are fixedly connected to the fixing plate. The upper continuous mold 6 is fixedly installed on the second springs 19. Multiple telescopic rods are fixedly connected between the fixing plate and the upper continuous mold 6, so that the upper continuous mold 6 slowly contacts the workpiece to avoid excessive pressure and damage to the workpiece.

[0023] Both the lower die 5 and the upper die 6 of the progressive die are existing technologies. The upper die 6 of the progressive die mainly includes a punching punch, a forming punch, and a pressure plate. The lower die 5 of the progressive die consists of a die cavity, a guide plate, an ejector device, a positioning pin, and an unloading structure. It completes punching, trimming, bending, forming and other processes in multiple stations in sequence, which will not be described in detail here. The support frame 2 is equipped with a limiting component and a collecting component. The limiting component includes two sliding grooves 7 opened on the support frame 2. The two sliding grooves 7 are slidably connected to two connecting frames 8. A bidirectional screw 9 is rotatably connected to the inner wall of one of the sliding grooves 7. The bidirectional screw 9 is threaded through the two connecting frames 8. A first motor 10 is fixedly installed on the side wall of the support frame 2. The rotating end of the first motor 10 is fixedly connected to the bidirectional screw 9. Belt conveyor components are installed on both connecting frames 8. The two belt conveyor components are symmetrically arranged.

[0024] The belt conveyor assembly includes two drive rollers 16 rotatably connected to the connecting frame 8. The two drive rollers 16 are driven by a transmission belt 17. Multiple transmission rollers are rotatably connected to the connecting frame 8, and all of the transmission rollers are attached to the transmission belt 17. A third motor 18 is fixedly installed on the upper end face of the connecting frame 8. The rotating end of the third motor 18 is fixedly connected to one of the drive rollers 16. The collection assembly includes multiple first springs 11 fixedly connected to the lower end face of the support frame 2. A collection plate 12 is fixedly connected to the multiple first springs 11. The collection plate 12 faces the drain port of the lower die 5 of the continuous mold. A rotating rod 13 is rotatably connected to the support frame 2. An elliptical plate 14 is fixedly connected to the side wall of the rotating rod 13 and is attached to the collection plate 12. A second motor 15 is fixedly installed on the side wall of the support frame 2. The rotating end of the second motor 15 is fixedly connected to the rotating rod 13. A protective pad made of rubber is provided on the side wall of the elliptical plate 14 to prevent the elliptical plate 14 from impacting and damaging the collection plate 12.

[0025] The detailed working process of this utility model is as follows:

[0026] The device is placed in the designated position, and then the first motor 10 starts working, causing the bidirectional screw 9 to rotate to adjust the distance between the two connecting frames 8. This ensures that the transmission belt 17 can stably contact the chassis plate, achieving stable conveying and improving the practicality of the device. The chassis plate to be processed is placed on the lower die 5 of the continuous die, and the cylinder 4 drives the upper die 6 of the continuous die to descend. The lower die 5 cooperates with the upper die 6 of the continuous die and pushes the chassis plate to achieve continuous processing of the chassis plate. The belt conveyor assembly set on the support frame 2 ensures accurate feeding of the chassis plate and avoids the chassis plate from being processed during the stamping process. The offset is designed to prevent the chassis plate from shifting due to stamping vibration or feeding inertia, thereby improving processing accuracy. Under the conveying of the third motor 18 and the drive roller 16, the transmission belt 17 moves to feed the chassis plate, avoiding excessive friction between the chassis plate and the transmission belt 17 that could affect feeding. During processing, the discharge port on the lower die 5 of the continuous die faces the collection plate 12, which collects the waste generated during processing. The second motor 15 works, the rotating rod 13 rotates, and the elliptical plate 14 continuously impacts the collection plate 12, causing the collection plate 12 to vibrate up and down, facilitating waste collection and improving the practicality of the device.
