Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a stamping structure for automotive parts processing. Background Technology

[0002] Existing stamping structures for automotive parts processing are mainly used for the efficient and mass production of automotive body panels (such as doors and hoods) and structural components (such as chassis brackets). The core of this technology lies in applying enormous pressure to metal sheets through molds to perform processes such as punching, blanking, bending, and deep drawing, thereby rapidly forming parts with complex shapes and precise dimensions. The significance of this technology is that it is not only the cornerstone of large-scale automotive production, greatly reducing manufacturing costs, but also capable of producing high-quality parts that combine lightweight and high strength, providing key support for improving vehicle safety, fuel economy, and overall quality. In existing stamping structures used for automotive parts processing, the stamping process and the mold assembly movement process are carried out independently. In order for the two dies to be aligned and complete the stamping, the working speed of the stamping machine and the moving speed of the mold assembly need to be adjusted to be consistent. However, long-term operation can easily lead to inconsistent speeds, resulting in a large number of defective parts. Furthermore, in the demolding process after stamping, existing stamping machines often require manual assistance, resulting in low demolding efficiency, which is not conducive to continuous production. Manual inspection and assisted demolding increase labor costs and safety hazards. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stamping structure for processing automotive parts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A stamping structure for processing automotive parts includes a base and a stamping machine fixedly connected to one side of the base. A base plate is fixedly connected to one side of the base, and a mold assembly is slidably connected to the base plate. A fixed platform is fixedly connected to the lower side of the stamping machine, and a telescopic cylinder is fixedly connected to the lower side of the fixed platform. A first mold is fixedly connected to the lower side of the telescopic cylinder, and a connecting rod is fixedly connected to one side of the first mold. A motor is fixedly connected to the base, and a gear is fixedly connected to the output end of the motor. The gear meshes with the mold assembly, and a protrusion is fixedly connected to the gear. A long rod is fixedly connected to one side of the motor, and a control switch is fixedly connected to one side of the long rod. A control circuit is installed between the long rod and the connecting rod.

[0005] Preferably, a horizontal plate is fixedly connected to the base, a sliding groove is opened on the horizontal plate, a sliding ring is slidably connected to the sliding groove, a first spring is fixedly connected between the sliding ring and the connecting rod, and a stop block is fixedly connected to the lower side of the connecting rod, with the stop block and the protrusion facing each other.

[0006] Preferably, the molding assembly includes a second mold and a slide plate fixedly connected to the lower side of the second mold. The base plate has a first slide rail and a second slide rail. The slide plate and the first slide rail are slidably connected. A rack is slidably connected to the second slide rail. The rack and the slide plate are connected by screw threads. The rack and the gear mesh with each other.

[0007] Preferably, a sleeve rod is fixedly connected to the lower side of the fixed platform, a second spring is fixedly connected inside the sleeve rod, a sliding rod is fixedly connected to one side of the second spring, the sliding rod and the sleeve rod are slidably connected, the sliding rod slides through the first mold, and a pressure plate is fixedly connected to one side of the sliding rod.

[0008] Preferably, a control board is fixedly connected to the upper side of the base, and a control knob and a display panel are fixedly connected to the control board.

[0009] Preferably, a rubber gasket is fixedly connected to the underside of the base plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model links the working process of the stamping machine with the moving process of the mold assembly. When each mold assembly moves to face the lower side of the stamping machine, the protrusion just touches the control switch. The control switch causes the motor to stop working for a period of time. During this period, the control line transmits a signal to the stamping machine to perform the stamping work, so that the two molds are completely matched during the stamping process and no defective products are produced due to mold misalignment. 2. Furthermore, during the demolding process after stamping, the protrusion abuts against the stop block, and the connecting rod shakes under the action of the first spring, which promotes the shaking of the first mold to complete the demolding process. At the same time, the first mold moves upward, causing the pressure plate to squeeze out the mold inside that has completed the stamping, which promotes the completion of the demolding process, saves time and effort, and demolds quickly, which is beneficial for continuous production and cost control.

[0013] Reference Figures 1-3A stamping structure for processing automotive parts includes a base 1 and a stamping press 2 fixedly connected to one side of the base 1. The stamping press 2 mainly stores energy by driving a flywheel with an electric motor, and then converts the rotational motion into the linear reciprocating motion of a telescopic cylinder 4 through a clutch and transmission mechanism (such as a crank connecting rod). This causes the first mold 5 and the second mold 20 installed on the telescopic cylinder 4 and the base plate 17 to close, thereby applying huge pressure to the raw material to complete the stamping or separation. This is prior art and will not be described in detail. A control board 28 is fixedly connected to the upper side of the base 1. A control knob 29 and a display panel 30 are fixedly connected to the control board 28. The stamping press 2 and the motor 8 can be started or stopped by different control knobs 29, and the number of stampings and the stamping speed can be recorded by the display panel 30. The press time is used to accurately reflect the quantity and speed of automotive parts production. A base plate 17 is fixedly connected to one side of the base 1, and a rubber pad is fixedly connected to the lower side of the base plate 17. A mold assembly is slidably connected to the base plate 17. The mold assembly includes a second mold 20 and a slide plate 19 fixedly connected to the lower side of the second mold 20. A first slide rail 18 and a second slide rail 21 are provided on the base plate 17. The slide plate 19 is slidably connected to the first slide rail 18. A rack 22 is slidably connected to the second slide rail 21. The rack 22 and the slide plate 19 are threadedly connected by screws 23. Different mold assemblies can be replaced according to production needs. The replacement process only requires turning the screws 23. A fixed platform 3 is fixedly connected to the lower side of the press 2. A telescopic cylinder 4 is fixedly connected to the lower side of the fixed platform 3. The telescopic cylinder 4 mainly... The telescopic cylinder 4 is constructed using nested multi-stage sleeves. Fluid pressure (hydraulic oil or compressed air) is used to progressively push the cylinder core, achieving a linear telescopic movement far exceeding its installation length. A sealing structure maintains stable pressure and movement. This is existing technology and will not be elaborated further. A first mold 5 is fixedly connected to the lower side of the telescopic cylinder 4. A sleeve rod 24 is fixedly connected to the lower side of the fixed platform 3. A second spring 25 is fixedly connected inside the sleeve rod 24. A sliding rod 26 is fixedly connected to one side of the second spring 25. The sliding rod 26 and the sleeve rod 24 are slidably connected. The sliding rod 26 slides through the first mold 5. A pressure plate 27 is fixedly connected to one side of the sliding rod 26. During demolding, the pressure plate 27 pushes out the stamped automotive parts from the first mold 5. A connecting rod 6 is fixedly connected to one side of the first mold 5. The base 1... A motor 8 is fixedly connected to the upper part of the base 1. A gear 9 is fixedly connected to the output end of the motor 8. A rack 22 meshes with the gear 9. A protrusion 10 is fixedly connected to the gear 9. When the protrusion 10 rotates to one side, it can abut against the control switch 12. When the protrusion 10 rotates to the other side, it can abut against the stop block 7. A long rod 11 is fixedly connected to one side of the motor 8. A control switch 12 is fixedly connected to one side of the long rod 11. A control line 13 is installed between the long rod 11 and the connecting rod 6. The control line 13 can transmit the signal from the control switch 12 to the connecting rod 6 and the motor 8, causing the motor 8 to stop for a period of time. Then, the signal is transmitted to the stamping machine 2 through the internal wires, so that the stamping machine 2 completes the stamping while the motor 8 is stopped for a period of time. A horizontal plate 16 is fixedly connected to the base 1. The horizontal plate 16 has a sliding groove.A sliding ring 14 is slidably connected to the slide groove. A first spring 15 is fixedly connected between the sliding ring 14 and the connecting rod 6. A stop block 7 is fixedly connected to the lower side of the connecting rod 6, and the stop block 7 is opposite to the protrusion 10.

[0014] In this invention, when stamping is required, the stamping machine 2 and motor 8 are first started by controlling knob 29. The output end of motor 8 drives gear 9 to rotate, gear 9 drives rack 22 to slide along second slide rail 21, rack 22 drives slide plate 19 to slide along first slide rail 18, slide plate 19 drives second mold 20 to move, gear 9 drives protrusion 10 to rotate, when protrusion 10 rotates to one side, it abuts control switch 12. After control switch 12 is abutted, the motor 8 is stopped for a period of time by electrical signal, and then the electrical signal is transmitted to connecting rod 6 through control line 13, and then the signal is transmitted to stamping machine 2 through connecting rod 6, so that stamping machine 2 completes the process during the time when motor 8 is stopped. During the stamping process, the telescopic cylinder 4 moves up and down, driving the first mold 5 to move up and down. The first mold 5 drives the connecting rod 6 to move up and down. The connecting rod 6 drives the sliding ring 14 to slide along the groove on the horizontal plate 16. The first mold 5 and the second mold 20 squeeze to complete the stamping process. After the stamping work is completed, the motor 8 starts again, driving the protrusion 10 to rotate to the other side and squeeze the abutment 7. The abutment 7 drives the connecting rod 6 to shake slightly under the action of the first spring 15. The connecting rod 6 drives the first mold 5 to shake slightly, promoting the demolding process. During the demolding process, the first mold 5 moves upward, and the stationary pressure plate 27 squeezes out the car parts in the first mold 5, finally completing the demolding.
