Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and particularly relates to a continuous stamping equipment and forming method for automobile sheet metal parts. Background Art

[0002] In the automotive manufacturing industry, the processing of sheet metal parts is a crucial link. With the development of the automotive industry, the requirements for the precision, efficiency, and quality of sheet metal parts are getting higher and higher. Traditional sheet metal part processing methods mostly use single stamping or multiple stamping.

[0003] When the existing stamping equipment stamps automobile sheet metal parts, the coil is placed on the unwinding roller, and then the coil is conveyed to the stamping equipment by a conveyor for stamping. Since the waste material of the coil after stamping is relatively long, it is not convenient for the staff to clean the stamping waste. Summary of the Invention

[0004] In order to improve the problem that the waste material of the coil after stamping is relatively long, making it inconvenient for the staff to clean the stamping waste, the present application provides a continuous stamping equipment and forming method for automobile sheet metal parts.

[0005] In the first aspect, the continuous stamping equipment for automobile sheet metal parts provided by the present application adopts the following technical solutions: A continuous stamping equipment for automobile sheet metal parts includes a frame. A stamping table is arranged inside the frame. A cross beam is fixed between the opposite inner sides of the frame. The cross beam is located above the stamping table. A moving seat is arranged below the cross beam. A punch is fixed to the bottom surface of the moving seat. Cylinders are fixed to both sides of the bottom surface of the cross beam. The bottom end of the piston rod of the cylinder is fixed to the top surface of the moving seat. A stamping hole is formed in the top surface of the stamping table. A cleaning component for cleaning stamping waste is arranged on the stamping table.

[0006] By adopting the above technical solutions, the stamping part is placed on the stamping table, and then the cylinder is started. The piston rod of the cylinder drives the moving seat to move downward, so that the moving seat drives the punch to move downward, and the punch passes through the stamping hole, thereby punching the workpiece from the stamping coil. Then, the cleaning component is used to clean the stamping waste after stamping, which is convenient for the staff to clean and recycle the stamping waste.

[0007] Preferably, a conveying port for conveying the stamping coil is formed in the side surface of the stamping table. The conveying port is communicated with the stamping hole. An installation block is fixed to the top surface of the stamping table. A first through groove is formed in the top surface of the installation block, and the first through groove vertically penetrates to the inner bottom surface of the conveying port. A moving block is slidably arranged vertically in the first through groove. A cutting knife is fixed to the bottom surface of the moving block. A resetting member for resetting the cutting knife after cutting the stamping coil is arranged on the installation block.

[0008] By adopting the above technical solution, when the moving seat drives the punch to stamp the metal coil downward, at the same time, during the downward movement of the moving seat, the moving seat also pushes the moving block downward, causing the moving block to drive the cutting knife downward, so that the cutting knife cuts the stamped waste material into multiple segments, thus facilitating the collection of the cut stamped waste material.

[0009] Preferably, the reset member includes sliders fixed on both side surfaces of the moving block. Sliding grooves are formed on the opposite inner side surfaces of the first through groove. The sliders are slidably arranged in the sliding grooves. A first spring is fixed to the bottom surface of the slider, and the bottom end of the first spring is fixed to the inner bottom surface of the sliding groove.

[0010] By adopting the above technical solution, after the workpiece stamping is completed, the piston rod of the cylinder drives the moving seat to move upward, causing the moving seat to gradually separate from the moving block. The slider moves upward under the elastic force of the first spring, causing the slider to drive the moving block upward, and the moving block drives the cutting knife upward to the initial position, thus facilitating the cutting of the stamped waste material by the cutting knife when stamping the workpiece next time.

[0011] Preferably, a discharge port is formed on one inner side surface of the conveying port, and a sliding port is formed on the other inner side surface of the conveying port. The cleaning assembly includes a driving block slidably arranged in the sliding port. There is a sliding groove on the side surface of the driving block close to the stamping coil. A top block is slidably arranged in the sliding groove. A second spring is fixed to the inner side wall of the sliding groove, and one end of the second spring is fixedly connected to the side surface of the top block. A driving assembly for driving the driving block to move along the width direction of the stamping table is arranged on the moving seat.

[0012] By adopting the above technical solution, when the moving seat drives the punch to stamp the coil downward, the moving seat also drives the driving assembly downward, causing the driving assembly to drive the driving block to move towards the direction close to the coil, so that the driving block drives the top block to move towards the direction close to the coil, and the side surface of the top block abuts against the side surface of the coil opposite to it, and the second spring is in a compressed state. When the punch stamps along the coil, the cutting knife also cuts the stamped waste material. Then the moving seat drives the punch to move upward. When the punch disengages from the stamped waste material, the top block pushes the stamped waste material towards the direction away from the driving block under the elastic force of the second spring, so that the stamped waste material passes through the discharge port and falls into the waste box.

[0013] Preferably, the driving assembly includes a driving rod fixed to the bottom surface of the moving seat. A second through groove is formed on the inner top surface of the sliding port. A first push block is fixed to the bottom surface of the driving rod, and the first push block can be inserted into the second through groove. A second push block is fixed to the side surface of the driving block away from the top block, and the second push block is located in the second through groove. The first push block can push the second push block towards the direction close to the stamping coil.

[0014] By adopting the above technical solution, when the moving seat drives the punch to move downward to punch the coil, the moving seat also drives the driving rod to move downward, the driving rod drives the first pushing block to move downward, so that the first pushing block pushes the second pushing block to move towards the coil, thereby making the second pushing block drive the driving block to move towards the coil, and further making the driving block drive the top block to move towards the coil, so that the side surface of the top block opposite to the coil is abutted. At this time, the second spring is in a compressed state, and it is convenient for the top block to push out the punching waste under the elastic force of the second spring when the punch moves upward and disengages from the coil.

[0015] Preferably, a first inclined surface is provided on the bottom surface of the first pushing block, and a second inclined surface is provided on the top surface of the second pushing block, and the first inclined surface and the second inclined surface can be attached to each other.

[0016] By adopting the above technical solution, a first inclined surface is provided on the bottom surface of the first pushing block, and a second inclined surface is provided on the top surface of the second pushing block. When the first pushing block moves downward, the first inclined surface pushes the second inclined surface to move, so that the second pushing block drives the driving block to move towards the coil.

[0017] Preferably, reset blocks are fixed on both side surfaces of the driving block, grooves are provided on the opposite inner side surfaces of the sliding opening, the reset blocks are slidably arranged in the grooves, a third spring is fixed on the side surface of the reset block close to the punching coil, and one end of the third spring far away from the reset block is fixed on the inner side wall of the groove.

[0018] By adopting the above technical solution, when the moving seat moves upward, the moving seat drives the second pushing block to move upward. When the second pushing block disengages from the first pushing block, the reset block drives the driving block to move to the initial state under the elastic force of the third spring.

When the punch stamps along the coil, the cutting knife also cuts off the stamping waste. Then the moving seat drives the punch to move upward. When the punch disengages from the stamping waste, the top block pushes the stamping waste to move away from the driving block under the elastic force of the second spring, so that the stamping waste passes through the discharge port and falls into the waste box; 3. When the moving seat drives the punch to move downward to stamp the coil material, the moving seat also drives the driving rod to move downward.

[0041] The implementation principle of a continuous stamping device for automobile sheet metal parts in an embodiment of the present application is as follows: Start the cylinder 17. The piston rod of the cylinder 17 drives the moving seat 15 to move downward, so that the moving seat 15 drives the punch 16 to move downward, and the punch 16 punches the coil. The punched workpieces fall into the aggregate box. When the moving seat 15 drives the punch 16 to punch the metal coil downward, at the same time, the moving seat 15 also pushes the moving block 42 downward during the downward movement process, so that the moving block 42 drives the cutting knife 43 to move downward, and the cutting knife 43 cuts the punched stamping waste into multiple sections. At the same time, the moving seat 15 also drives the driving rod 6 to move downward, and the driving rod 6 drives the first pushing block 61 to move downward, so that the first pushing block 61 pushes the second pushing block 63 to move toward the direction close to the coil, and the second pushing block 63 drives the driving block 53 to move toward the direction close to the coil, and the driving block 53 drives the top block 55 to move toward the direction close to the coil, so that the side surface of the top block 55 opposite to the coil is abutted. At this time, the second spring 56 is in a compressed state. After the punch 16 finishes punching, the moving seat 15 drives the punch 16 to move upward, and the cutting knife 43 moves upward to the initial state under the elastic force of the first spring 45. When the punch 16 moves upward and disengages from the coil, the top block 55 pushes out the stamping waste under the elastic force of the second spring 56, so that the waste passes through the discharge port 5 and falls into the waste box 51, thereby facilitating the staff to collect and clean the stamping waste.

[0042] Meanwhile, the sensor 71 fails to detect the coil signal and transmits the signal to the controller 7. The controller 7 controls the motor 28 to start, so that the output shaft of the motor 28 drives the driving roller 27 to rotate. The driving roller 27 drives the coil to move into the conveying port 18. When the front end of the coil moves above the sensor 71, the sensor 71 transmits the detected signal to the controller 7, so that the controller 7 controls the motor 28 to shut down, stopping the conveyance of the coil. Then, it is convenient to start the cylinder 17, and the piston rod of the cylinder 17 drives the moving seat 15 to move downward, and the moving seat 15 drives the punch 16 to move downward to punch the coil.

[0043] The embodiment of the present application also discloses a continuous stamping and forming method for automobile sheet metal parts, including the following steps: S1: Install the coil on the rotating roller 31, and then pass the conveying end of the coil through between the driving roller 27 and the transmission roller 23, so that the conveying end of the coil is inserted into the conveying port 18. S2: Then start the cylinder 17, and the piston rod of the cylinder 17 drives the moving seat 15 to move downward, and the moving seat 15 drives the punch 16 to move downward, so that the punch punches the coil. S3: After stamping, the top block 55 fixes the stamping waste against the stamping table 11. S4: Then start the motor 28 again, and the output shaft of the motor 28 drives the driving roller 27 to rotate, and the driving roller 27 drives the coil to move into the conveying port 18, so as to facilitate continuous stamping of the coil.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
