Description

Technical Field

[0001] This utility model relates to the field of metal processing, and in particular to a stamping auxiliary device for parts. Background Technology

[0002] Stamping of parts is a key process in hardware processing, auto parts production and other fields. The feeding accuracy, vibration buffering effect and material change continuity of stamping auxiliary devices directly affect the efficiency of stamping operations, the quality of parts and the service life of equipment.

[0003] Traditional stamping auxiliary devices rely heavily on manual feeding and unloading of parts. Operators need to frequently approach the high-pressure stamping area, which not only results in low work efficiency but also poses significant safety hazards. Furthermore, the vibration generated during the stamping process lacks an effective buffer structure, which can easily lead to part deformation and die wear, seriously affecting the stability of stamping quality. In addition, the material changing process is mostly manual. These shortcomings make it difficult to meet the requirements of modern stamping production for high efficiency, safety, stability, and flexible adaptability, thus restricting the improvement of production efficiency and product quality and affecting the industry's demand for precision stamping operations.

[0004] Therefore, those skilled in the art have provided a component stamping auxiliary device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a component stamping auxiliary device. This device integrates automatic feeding, shock absorption, and cyclic material changing designs, solving the problems of excessive manual intervention, high vibration, and low material changing efficiency in traditional stamping auxiliary devices. The automatic feeding module achieves automated component transfer through electric actuators and electromagnets, eliminating the need for frequent manual operation and significantly improving feeding efficiency. The shock absorption system absorbs stamping vibration through elastic buffers and hydraulic buffer cylinders, preventing component deformation and equipment wear, ensuring stamping quality and device lifespan. The cyclic material changing structure, utilizing telescopic top blocks and a rotary feeding mechanism, can continuously complete the actions of picking up finished products and placing raw materials, adapting to the stamping production of components of different specifications. It is suitable for hardware processing, auto parts production, and other scenarios, achieving efficient and stable stamping assistance and improving production convenience and professionalism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A component stamping auxiliary device includes a stamping base with four buffer chambers. A hydraulic buffer cylinder is fixedly installed at the bottom of each buffer chamber. A piston block is slidably engaged within each hydraulic buffer cylinder. An elastic buffer element is fixedly installed at the top of each piston block. A pressure block is fixedly installed at the top of each elastic buffer element. Hydraulic cylinders are fixedly installed on both sides of the stamping base corresponding to the positions of the hydraulic buffer cylinders. A connecting rod is fixedly installed on the stamping base, and an electric rotator is fixedly installed at the end of the connecting rod. An L-shaped bracket is fixedly installed on the stamping base. Two limiting rods are fixedly installed between the top of the stamping base and the bottom of the top of the L-shaped bracket, and pressure plates slidably pass through both limiting rods. The above technical solution constructs a double-layer buffer structure by setting four buffer chambers within the stamping base and hydraulic buffer cylinders fixed at the bottom of the chambers. This is combined with a sliding piston block within the hydraulic buffer cylinder, an elastic buffer element at the top of the piston block, and a pressure block at the top of the elastic buffer element. In conjunction with corresponding hydraulic cylinders on both sides of the stamping base, the elastic buffer element initially absorbs vibration during stamping. Then, the piston block squeezes the hydraulic oil within the hydraulic buffer cylinder, and the hydraulic oil flows into the hydraulic cylinder through an oil pipe, achieving secondary force relief and significantly reducing stamping impact. A connecting rod fixed on the stamping base and an end-mounted electric rotary motor form an automatic feeding drive source. The L-shaped bracket and two limiting rods fixed between the stamping base and the L-shaped bracket provide stable guidance for the sliding pressure plate, preventing it from shifting during stamping. This structure ensures both the stamping quality and equipment lifespan through double buffering, while the electric rotary motor enables automated feeding, and the limiting rods ensure stamping accuracy. It solves the problems of high vibration, manual feeding reliance, and easy shifting during stamping in traditional stamping auxiliary devices, improving stamping efficiency and stability.

[0007] Furthermore, a stamping machine is fixedly installed on the top of the L-shaped bracket, and the output end of the stamping machine is fixedly connected to the pressure plate via a telescopic rod; Through the above technical solution, by fixing a stamping machine on the top of the L-shaped bracket and connecting the output end of the stamping machine to the pressure plate through a telescopic rod, the stamping machine can accurately transmit driving force through the telescopic rod, driving the pressure plate to rise and fall stably along the limit rod, ensuring that the stamping pressure and stroke are controllable, providing stable power for the stamping of parts, and improving the accuracy and reliability of the stamping process.

[0008] Furthermore, a rotating rod is fixedly installed inside the output end of the electric rotator, a crossbar is fixedly installed at the top of the rotating rod, and electromagnets are fixedly installed below both ends of the crossbar; The above technical solution involves fixing a rotating rod at the output end of an electric rotator, a crossbar at the top of the rotating rod, and electromagnets at both ends of the crossbar. The electric rotator can drive the crossbar to rotate, and the electromagnets can attract parts to achieve automatic feeding and picking, reducing manual intervention.

[0009] Furthermore, each of the hydraulic cylinders is connected to a corresponding hydraulic buffer cylinder via an oil pipe, and a return pump is fixedly installed on the top of each hydraulic cylinder; The above technical solution connects each hydraulic cylinder to a corresponding hydraulic buffer cylinder via oil pipes, and a return pump is fixed on top of each hydraulic cylinder to achieve hydraulic oil circulation. After pressing, the return pump draws back the hydraulic oil, which helps the piston block to reset and ensures the buffer system can be reused.

[0010] Furthermore, a mold block is fixedly installed on the top of the stamping base, a telescopic top block is fixedly installed inside the mold block, and a mold groove is opened below the pressure plate; The above technical solution involves fixing a mold block on the top of the stamping base, fixing a telescopic top block inside the mold block, and opening a mold groove below the pressure plate. The mold groove and the mold block work together to achieve precise stamping of parts, and the telescopic top block can eject the finished product, improving the convenience of material handling and stamping quality.

[0011] Furthermore, a controller is fixedly installed on the stamping base, and the controller controls the operation of the electric rotator, electromagnet, reflux pump, telescopic top block and stamping machine; The above technical solution, by fixing a controller on the stamping base, allows the controller to uniformly control the electric rotator, electromagnet, return pump, telescopic top block and stamping machine, which can coordinate the orderly linkage of various components, avoid disordered operation, ensure the continuity of feeding, stamping, buffering and unloading processes, and improve the automation and operational stability of the device.

[0012] Furthermore, multiple buffer rods are fixedly installed below the pressure plate; By fixing multiple buffer rods under the pressure plate, the buffer rods can contact the pressure block first during stamping, triggering the buffer system in advance, reducing the direct impact of the pressure plate, further enhancing the vibration absorption effect, and protecting parts and equipment.

[0013] This utility model has the following beneficial effects: This utility model proposes a stamping auxiliary device for parts, which integrates automatic feeding, buffering and shock absorption, and cyclic material changing design, solving the problems of traditional devices such as high manual labor, large vibration, and slow material changing. The automatic feeding module uses an electric rotary motor and electromagnet to achieve automated transfer, improving feeding efficiency. The buffering system uses elastic buffer components and hydraulic buffer cylinders to absorb shock and prevent part deformation and equipment wear. The cyclic material changing structure uses a telescopic top block and a turntable feeding to continuously complete the picking of finished products and placing of raw materials. It is suitable for parts of various specifications and applicable to hardware processing and auto parts production, achieving efficient and stable stamping assistance and improving convenience and professionalism.

Two limiting rods 11 are fixedly installed between the top of the stamping base 1 and the bottom of the top of the L-shaped bracket 10. Both limiting rods 11 are slidably inserted through a pressure block. Plate 8, by setting four buffer chambers 21 in the stamping base 1 and hydraulic buffer cylinders 23 fixed at the bottom of the chambers, combined with piston block 22 slidably engaged in the hydraulic buffer cylinder 23, elastic buffer member 24 at the top of the piston block 22 and pressure block 17 at the top of the elastic buffer member 24, a double-layer buffer structure is constructed. With the hydraulic cylinders 14 correspondingly set on both sides of the stamping base 1, the elastic buffer member 24 can initially absorb the vibration force during stamping, and then the piston block 22 squeezes the hydraulic oil in the hydraulic buffer cylinder 23. The hydraulic oil flows into the hydraulic cylinder 14 through the oil pipe 16 to achieve secondary unloading, which greatly reduces the impact of stamping. The connecting rod 2 fixed on the stamping base 1 and the end electric rotator 3 form an automatic feeding drive source. The L-shaped bracket 10 and the two limiting rods 11 fixed between the stamping base 1 and the L-shaped bracket 10 provide stable guidance for the sliding plate 8, and prevent the plate 8 from deviating during stamping. This structure not only ensures the stamping quality of parts and the life of equipment through double buffering, but also achieves automated feeding through electric rotator 3 and ensures stamping accuracy through limit rod 11. It solves the problems of large vibration, manual feeding, and easy deviation in traditional stamping auxiliary devices, thus improving the efficiency and stability of stamping operations.

[0018] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides another specific embodiment: A stamping machine 9 is fixedly installed on the top of the L-shaped bracket 10. The output end of the stamping machine 9 is fixedly connected to the pressure plate 8 via a telescopic rod 20. By fixing the stamping machine 9 on the top of the L-shaped bracket 10 and connecting the output end of the stamping machine 9 to the pressure plate 8 via the telescopic rod 20, the stamping machine 9 can accurately transmit driving force through the telescopic rod 20, driving the pressure plate 8 to rise and fall stably along the limit rod 11, ensuring that the stamping pressure and stroke are controllable, providing stable power for the stamping of parts, and improving the accuracy and reliability of the stamping process.

Each hydraulic cylinder 14 is connected to a corresponding hydraulic buffer cylinder 23 through an oil pipe 16. A return pump 15 is fixedly installed on the top of each hydraulic cylinder 14. Each hydraulic cylinder 14 is connected to the corresponding hydraulic buffer cylinder 23 through an oil pipe 16. The return pump 15 is fixed on the top of each hydraulic cylinder 14 to realize hydraulic oil circulation. After stamping, the return pump 15 draws out the hydraulic oil. The return of hydraulic oil helps the piston block 22 to reset, ensuring the repeated use of the buffer system. A mold block 12 is fixedly installed on the top of the stamping base 1, and a telescopic top block 13 is fixedly installed inside the mold block 12. A mold groove 19 is opened below the pressure plate 8. By fixing the mold block 12 on the top of the stamping base 1, fixing the telescopic top block 13 inside the mold block 12, and opening the mold groove 19 below the pressure plate 8, the mold groove 19 and the mold block 12 cooperate to achieve precise stamping of parts. The telescopic top block 13 can eject the finished product, improving the convenience of material handling and stamping quality. A controller 18 is fixedly installed on the stamping base 1. The controller 18 controls the electric rotary motor 3, the electromagnet 5, and the return flow. Pump 15, telescopic top block 13, and stamping machine 9 operate. By fixing controller 18 on stamping base 1, controller 18 can uniformly control electric rotary motor 3, electromagnet 5, return pump 15, telescopic top block 13, and stamping machine 9. This can coordinate the orderly linkage of various components, avoid disordered operation, ensure the continuity of feeding, stamping, buffering, and unloading processes, and improve the automation and operational stability of the device. Multiple buffer rods 7 are fixedly installed below the pressure plate 8. By fixing multiple buffer rods 7 below the pressure plate 8, the buffer rods 7 can contact the pressure block 17 first during stamping, triggering the buffer system in advance, reducing the direct impact of the pressure plate 8, further enhancing the vibration absorption effect, and protecting parts and equipment.

[0019] Working principle: The operator starts the device through controller 18. The electric rotator 3 drives the rotating rod 4 to rotate. The electromagnets 5 at both ends of the crossbar 6 are energized to attract the parts to be stamped. When the crossbar rotates to the position of the mold block 12, the electromagnets 5 are de-energized, and the parts are placed on the mold block 12. Then the crossbar 6 rotates away. The stamping machine 9 drives the pressure plate 8 to descend along the limit rod 11 through the telescopic rod 20. The buffer rod 7 first contacts the pressure block 17, and the elastic buffer 24 contracts to absorb part of the vibration force. Then the mold groove 19 of the pressure plate 8 contacts the mold block 12 to stamp the parts. When the pressure plate 8 continues to apply pressure, the pressure block 17 pushes the piston block 22 to move down. The hydraulic oil in the hydraulic buffer cylinder 23 enters the hydraulic cylinder 14 through the oil pipe 16 to further absorb the vibration force. After stamping, the stamping machine 9 drives the pressure plate 8 to move up through the telescopic rod 20. The buffer rod 7 leaves the pressure block 17, the elastic buffer 24 returns to its original position, and the return pump 15 draws the hydraulic oil in the hydraulic cylinder 14 back to the hydraulic buffer cylinder 23, and the piston block 22 resets. The telescopic top block 13 lifts the stamped parts, and the electric rotator 3 drives the rotating rod 4 and the crossbar 6 to rotate again. The electromagnet 5 at one end attracts the stamped parts, and the other end attracts the new parts to be stamped. After rotation, the new parts are placed on the mold block 12, and the stamped parts are moved aside to complete the cycle. The whole process is coordinated and controlled by the controller 18 to operate the electric rotator 3, the electromagnet 5, the stamping machine 9, the return pump 15 and the telescopic top block 13. The stamping base 1 provides installation support for each component, the L-shaped bracket 10 fixes the stamping machine 9, and the buffer cavity 21 accommodates the hydraulic buffer cylinder 23 and other buffer components.
