Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a self-propelled continuous stamping device and method for workpieces. Background Technology

[0002] A stamping device is a special process equipment used in cold stamping to process metal or non-metal materials into parts or semi-finished products. It is called a cold stamping die, commonly known as a cold stamping mold. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts. Currently, in the process of processing automotive parts, manual loading and fixing of the sheet metal are required. After fixing, the parts are stamped by the stamping mechanism. After stamping, the parts need to be removed in time. This results in a discontinuous stamping process, which is not conducive to ensuring processing efficiency. Furthermore, tools are required during the unloading process, and there are certain safety hazards during the unloading process.

[0003] Based on this, a self-propelled continuous stamping device and method for workpieces are now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

The mounting plate is connected to the base via a connecting frame (not shown in the figure). A storage bin for storing raw materials is located at the end of the mounting plate. A locking slider for locking the raw materials is located at the lower end of the storage bin. Two locking sliders are connected to a locking push component for pressing them together. Below the storage bin is a lower die component for loading the material. The lower die component includes a material carrier seat with a clamping mechanism for pressing the raw materials. The lower end of the material carrier seat is connected to the base via a sliding mechanism. The mounting plate has a stamping component for stamping the raw materials. The stamping component includes a stamping column slidably disposed on the mounting plate. A traction block is located at the upper end of the stamping column. The traction block is connected to the mounting plate via a first spring. The traction block is connected to a stamping drive mechanism for driving it downward. The material carrier seat is connected to a traction mechanism for driving it to reciprocate along a slide rail mechanism.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In an optional embodiment: the traction mechanism includes a traction vertical rod connected to the middle position of the lower end of the material carrier. A traction column is slidably mounted horizontally at the lower end of the traction vertical rod. A reset block at one end of the traction column is connected to the traction vertical rod via a second spring. The other end of the traction column is connected to a drive gear frame. A guide base at the lower end of the drive gear frame is slidably mounted on a second guide rod. Both ends of the second guide rod are connected to reinforcing rods. The reinforcing rods are connected to a second positioning frame at the upper end of the base. The cooperation between the second guide rod and the guide base makes the reciprocating movement of the drive gear frame more stable. A rack is provided on the upper and lower inner walls of the drive gear frame. A half gear is fitted between the upper and lower racks. The half gear is connected to a drive motor for driving its rotation. The drive motor is mounted on a base at the upper end of the base.

[0007] In an optional embodiment: the stamping drive mechanism includes a drive disc coaxially arranged with the half gear, a second shaft is provided on the outer side of the drive disc away from the center, a first shaft is provided on the outer side of the traction block, and a transmission link is rotatably provided between the first shaft and the second shaft.

[0008] In the optional solution: the upper end of the second positioning frame is provided with a limiting baffle that cooperates with the material carrier.

[0009] In an optional embodiment: the sliding mechanism includes two transverse slides disposed at the lower end of the material carrier, each transverse slide having a first guide rod slidably mounted thereon, the two ends of the first guide rod being respectively connected and fixed to a second positioning frame at the upper end of the base.

[0010] In an optional embodiment: the clamping mechanism includes a clamping groove disposed on the upper end of the material carrier, a discharge port for unloading is provided in the middle of the clamping groove, two clamping blocks are slidably disposed in the clamping groove, a pressing plate for supporting the raw material is provided at the pressing end of the clamping block, a cutting hole is provided in the middle of the pressing plate, the two cutting holes form a cutting channel matching the stamping position, an avoidance hole is provided at the outer end of the clamping block, a sliding crossbar is slidably disposed in the avoidance hole, the outer end of the sliding crossbar passes through a through hole on the outer side of the material carrier, a pressure roller is rotatably disposed at the outer end of the sliding crossbar, and the clamping block is connected and fixed to the inner wall of the clamping groove by a third spring.

[0011] In an optional configuration: the clamping mechanism further includes clamping side plates symmetrically arranged on both sides of the sliding mechanism. The clamping side plates cooperate with the pressure roller to press the raw material tightly. One end of the clamping side plate is connected to the second positioning frame of the sliding mechanism, and the other end of the clamping side plate is provided with a discharge ramp for guiding the pressure roller. The inner side of the clamping side plate near the stamping position is provided with a derailment ramp, which matches the pressure roller. The outer side of the upper end of the pressure roller is rounded, and the fixed shaft at the lower end of the pressure roller is slidably connected to the sliding crossbar. The pressure roller and the sliding crossbar are connected by a support spring. When the pressure roller returns along the inner wall of the drive gear frame, under the guidance of the derailment ramp, the pressure roller will separate from the clamping side plate and will not contact the clamping side plate. As the pressure roller continues to move, the pressure roller will contact the outer side of the discharge ramp. At this time, under the guidance of the outward V-shaped structure of the discharge ramp, the two pressure rollers will separate, thereby pulling the two clamping blocks apart, so that the processed product falls out of the discharge port, completing the automatic unloading.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-7 As shown, the self-propelled continuous stamping device for workpieces includes a base 11 and a mounting plate 14 disposed above it. The mounting plate 14 is connected to the base 11 via a connecting frame (not shown in the figure). The end of the mounting plate 14 is provided with a storage box 13 for storing raw materials. The lower end of the storage box 13 is provided with a locking slider 31 for locking the raw materials. The two locking sliders 31 are connected to a locking push component for driving them to press against each other. Below the storage bin 13 is a lower die component for loading materials. The lower die component includes a material carrier 12. The material carrier 12 is provided with a clamping mechanism for pressing the raw material. The lower end of the material carrier 12 is connected to the base 11 through a sliding mechanism. The mounting plate 14 is provided with a stamping component for stamping the raw material. The stamping component includes a stamping column 18 slidably disposed on the mounting plate 14. The upper end of the stamping column 18 is provided with a traction block 15. The traction block 15 is connected to the mounting plate 14 through a first spring 17. The traction block 15 is connected to a stamping drive mechanism for driving it to move downward. The material carrier 12 is connected to a traction mechanism for driving it to reciprocate along the slide rail mechanism. The traction mechanism causes the material carrier 12 to reciprocate between the storage bin 13 and the traction block 15, thereby completing automatic loading and automatic punching. The traction mechanism includes a traction vertical rod connected to the middle position of the lower end of the material carrier 12. A traction column 35 is slidably provided at the lower end of the traction vertical rod. A reset block 32 at one end of the traction column 35 is connected to the traction vertical rod through a second spring 34. The other end of the traction column 35 is connected to the drive gear frame 37. The guide base 36 at the lower end of the drive gear frame 37 is slidably disposed on the second guide rod 24. The two ends of the second guide rod 24 are connected to the reinforcing rod 23. The reinforcing rod 23 is connected to the second positioning frame 22 at the upper end of the base 11. The cooperation between the second guide rod 24 and the guide base 36 makes the reciprocating movement of the drive gear frame 37 more stable. A rack is provided on the upper and lower inner walls of the drive gear frame 37. A half gear 39 is provided between the upper and lower racks. The half gear 39 is connected to a drive motor 38 for driving its rotation. The drive motor 38 is disposed on the base at the upper end of the base 11. Thus, the drive motor 38 drives the half gear 39 to rotate. The half gear 39 will intermittently mesh with the upper and lower racks, thereby traction the drive gear frame 37 to reciprocate. The stamping drive mechanism includes a drive disc 25 coaxially arranged with the half gear 39. A second shaft 26 is provided on the outer side of the drive disc 25 away from the center. A first shaft 16 is provided on the outer side of the traction block 15. A transmission link 19 is rotatably provided between the first shaft 16 and the second shaft 26. When the drive disc 25 rotates, the transmission link 19 will cooperate with the first shaft 16 to drive the traction block 15 to move up and down reciprocally, thereby providing power for stamping. The second positioning frame 22 here is provided with a limiting baffle 55 that cooperates with the material carrier 12. When the material carrier 12 contacts the limiting baffle 55, it means that the stamping position has been reached. At this time, the drive gear frame 37 will continue to move, but the traction column 35 can slide at the lower end of the traction vertical rod to keep the position of the material carrier 12 unchanged. The sliding mechanism includes two transverse slides 49 disposed at the lower end of the material carrier 12. A first guide rod 20 is slidably disposed on each transverse slide 49. The two ends of the first guide rod 20 are respectively connected and fixed to the second positioning frame 22 at the upper end of the base 11, so that the material carrier 12 can slide smoothly along the first guide rod 20. The clamping mechanism includes a clamping groove 41 located on the upper end of the material carrier 12. A material discharge port 44 for unloading is located in the middle of the clamping groove 41. Two clamping blocks 45 are slidably arranged in the clamping groove 41. The pressing end of the clamping block 45 is provided with a pressing plate 43 for supporting the raw material. A cutting hole 42 is located in the middle of the pressing plate 43. The two cutting holes 42 form a cutting channel that matches the stamping position. An avoidance hole is provided at the outer end of the clamping block 45. A sliding crossbar 47 is slidably arranged in the avoidance hole. The outer end of the sliding crossbar 47 passes through a through hole on the outside of the material carrier 12. A pressure roller 46 is rotatably arranged at the outer end of the sliding crossbar 47. The clamping block 45 is connected and fixed to the inner wall of the clamping groove 41 by a third spring 48. When the pressure roller 46 is pressed, the two clamping blocks 45 can press and lock the raw material. The clamping mechanism also includes clamping side plates 27 symmetrically arranged on both sides of the sliding mechanism. The clamping side plates 27 cooperate with the pressure roller 46 to clamp the raw material. One end of the clamping side plate 27 is connected to the second positioning frame 22 of the sliding mechanism, and the other end of the clamping side plate 27 is provided with a discharge ramp 30 for guiding the pressure roller 46. The inner side of the clamping side plate 27 near the stamping position is provided with a derailment ramp 54, which matches the pressure roller 46. The outer side of the upper end of the pressure roller 46 is rounded, which makes the cooperation between the derailment ramp 54 and the pressure roller 46 smoother. It should be noted that the pressure roller 46 here... The fixed shaft at the lower end is slidably connected to the sliding crossbar 47, and the pressure roller 46 and the sliding crossbar 47 are connected by a support spring. When the pressure roller 46 returns along the inner wall of the drive tooth frame 37, under the guidance of the derailment inclined plate 54, the pressure roller 46 will separate from the clamping side plate 27 and will not contact the clamping side plate 27. As the pressure roller 46 continues to move, the pressure roller 46 will contact the outer side of the unloading inclined plate 30. At this time, under the guidance of the outward V-shaped structure of the unloading inclined plate 30, the two pressure rollers 46 will separate, thereby pulling the two clamping blocks 45 apart, so that the processed product falls out of the discharge port 44 and completes the automatic unloading. A collecting component is also provided above the base 11. The collecting component includes an inclined collecting guide plate 28. The collecting guide plate 28 is matched with the unloading ramp 30. The collecting guide plate 28 is connected and fixed to the base 11 through the first positioning frame 21. A guide notch 29 is provided on the collecting guide plate 28. The guide notch 29 can avoid interference and facilitate the parts to pass through the collecting guide plate 28. It should be noted that the guide notch 29 is relatively narrow and will not affect the sliding of the parts. The locking and pushing component includes a locking sliding hole located on the outer side of the lower end of the storage box 13. A locking slider 31 is fitted in the locking sliding hole. At least one discharge side plate 51 is provided on the outer side of the locking slider 31. The discharge side plate 51 is slidably mounted on the discharge guide rod 50. The discharge guide rod 50 is connected and fixed to the outer side of the storage box 13. A discharge tail plate 53 is provided at the outer end of the discharge guide rod 50. The discharge tail plate 53 and the discharge side plate 51 are connected and fixed by a discharge spring 52. In this way, the discharge spring 52 can pull the two locking sliders 31 closer to each other, thereby pressing and fixing the bottom of the raw material.

[0025] The above embodiments disclose a self-propelled continuous stamping device for workpieces. In actual use, the raw material to be processed is placed in the storage bin 13. The traction mechanism drives the carrier seat 12 to slide along the first guide rod 20. Under the push of the pressure roller 46, the two unloading push rods 40 are pushed, and the raw material at the bottom of the storage bin 13 falls into the carrier seat 12. When the carrier seat 12 moves away from the storage bin 13, the locking slider 31 can continue to press the bottom layer of raw material tightly. As the carrier seat 12 moves toward the traction block 15, the pressure roller 46 on the carrier seat 12 will first contact the unloading inclined plate 30, and then cooperate with the clamping side plate 27 to clamp and fix the raw material with the two clamping blocks 45. Then, under the action of the stamping drive mechanism, the workpiece is pulled... The guide block 15 moves toward the material carrier 12 to complete the stamping process on the raw material. After completion, the traction mechanism takes the material carrier 12 back along the first guide rod 20. Under the action of the derailment inclined plate 54 and guided by the derailment inclined plate 54, the pressure roller 46 separates from the clamping side plate 27 and no longer contacts the clamping side plate 27. As the pressure roller 46 continues to move, the pressure roller 46 contacts the outer side of the unloading inclined plate 30. At this time, under the guidance of the outward V-shaped structure of the unloading inclined plate 30, the two pressure rollers 46 separate, thereby pulling the two clamping blocks 45 apart, so that the processed product falls out of the discharge port 44, completing the automatic unloading, and is then collected by the collecting component. The whole process does not require manual loading and unloading, which effectively improves the processing efficiency and safety.

[0026] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
