Description

Technical Field

[0001] The invention belongs to the technical field of stamping equipment, in particular to a stamping die for processing mining machinery parts. Background Art

[0002] The stamping die used in the processing of mining machinery parts is a special process equipment. It processes materials (metal or non-metal) into parts or semi-finished products in the cold stamping process. For flat plates and round parts on mining equipment, it is particularly necessary to use a blanking die process to complete the stamping forming. For circular ring parts, stamping dies are usually used for processing and manufacturing.

[0003] In the prior art, the stamping die for processing mining machinery parts uses a punching head to punch out a target-shaped plate toward the plate during use. However, after punching, the formed plate is either stuck inside the punching head or falls on the work surface. For the target plate formed after punching, special material picking and stripping processes are required, especially for the forming of annular plates. Since both the outer side and the inner side have sufficient punching contact area, the actual damping is more obvious. The formed annular plates basically remain stuck inside the punching head. On the one hand, stripping is more difficult, and on the other hand, the collection and transfer operations are complicated, making it difficult for the punching head to continuously perform stamping processing. Stripping and removal are required after stamping, which greatly reduces the stamping efficiency and has a poor use effect.

[0004] In addition, the stamping dies used for processing mining machinery parts in the prior art have scratches and burrs on the outer arc surface of the annular plate after the blanking process is completed. Special surface treatment processes are often required after forming and transferring, especially polishing the outer side of the formed ring. However, this requires the investment of special loading and unloading operations and polishing equipment, which is actually time-consuming and labor-intensive. In the stamping forming steps, synchronous processing cannot be achieved, and the manufacturing and processing efficiency of mining machinery parts is low. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, the embodiment of the present invention provides a stamping die for processing mining machinery parts, including a mounting seat 1, a mounting plate 2 is movably sleeved inside the mounting seat 1, a punch head 3 is provided at the bottom of the mounting seat 1, the punch head 3 is rotatably mounted between the mounting plates 2 on both sides, an auxiliary punching portion 5 is fixedly sleeved inside the punch head 3, an automatic material stripping portion 6 is slidably installed inside the punch head 3, a charging assembly 8 is rotatably provided at the bottom of the mounting seat 1, fixed grinding portions 10 are fixedly provided on both sides of the charging assembly 8, a power unit 1 4 is fixedly provided on the side of the mounting plate 2, the power unit 1 4 controls the flipping of the punch head 3, and a power unit 2 9 is provided at the bottom of the mounting seat 1.

[0034] The automatic material-removing part 6 comprises an intermediate rod 61, a connecting plate 62, a material-removing rod 63 and a damping sleeve 64. The connecting plates 62 are symmetrically distributed at both ends of the intermediate rod 61 and are fixedly connected to the intermediate rod 61. The material-removing rod 63 is fixed on the connecting plate 62.

[0035] The loading assembly 8 includes a connecting column 81 , a side groove 82 , a clamping plate 83 , and a second spring 84 . The clamping plate 83 is movably sleeved in the side groove 82 . The loading assembly 8 is located above the automatic material unloading portion 6 .

[0036] By utilizing the inner surface of the stamping ring 32 and the outer surface of the stamping column 52 in the auxiliary stamping part 5, the formed circular ring sheet is nested in the stamping ring 32 after punching, and relies on its own damping force to maintain stability, ensuring that after each stamping, the formed circular ring can rely on the damping of its own contact surface to stably fit in the stamping ring 32, thereby ensuring stability during the flipping action.

[0037] Embodiment 1: During the stamping process, the hydraulic push rod 11 installed and fixed on the external stamping equipment is actuated to push the mounting seat 1 and the stamping head 3 downward to keep the sheet to be stamped below the stamping die. As the stamping ring 32 in the stamping head 3 and the stamping column 52 in the auxiliary stamping part 5 contact the top of the sheet, the spring 13 is further compressed in the clamping state, so that the mounting seat 1 and the loading assembly 8 continue to move downward, and the connecting column 81 in the loading assembly 8 abuts against the upper end of the stamping column 52 in the auxiliary stamping part 5. The hydraulic push rod 11 continues to apply pressure, and the stamping ring 32 and the stamping column 52 stamp out the target circular ring downward, and the target circular ring is nested in the stamping ring 32. As the formed target circular ring is pressed into the stamping ring 32, the automatic stripping part 6 is pushed upward to move upward, so that the upper end of the stripping rod 63 located above moves Until it is flush with the end of the top stamping ring 32, then the stamping die is lifted upward, the bottom plate moves, and the power unit 4 is started to drive the gear 34 to rotate, so that the punch head 3 flips 180 degrees, and the stamping ring 32 located at the top moves to the bottom, and the material with the nested target ring rotates to the top, and the next round of stamping processing is carried out again. As the bottom molded ring is punched and nested in the stamping ring 32, the internal automatic material stripping unit 6 is synchronously pushed to move upward, and at the same time, the top nested molded ring is pushed upward, and during the pushing process, the top molded ring is directly inserted upward onto the outer surface of the charging assembly 8, and while squeezing the clamping plate 83 from the bottom for compression, it is stably sleeved on the outside of the clamping plate 83, and then the stamping die moves upward again to reset and rotate, completing the automatic material stripping and swinging of the molded ring after stamping.

[0038] First, by using the reversible punch head 3 and cooperating with the automatic material stripping part 6 with internal sliding sleeve, after the punching and forming is completed, the formed ring is nested in the punch head 3 and turned upward after flipping. By using the punching action of the other end after flipping, the internal automatic material stripping part 6 is automatically pushed upward when the punching occurs, so that the previously punched formed ring is ejected upward during the punching, and the charging component 8 adapted at the top during the punching process is cooperated to push the top formed and nested ring product upward to the charging component while punching. 8, completes automatic material stripping, and strips out from the punch head 3, so that in the continuous punching process, continuous punching and material stripping actions can be achieved by simply flipping, which greatly improves the punching efficiency, and through the adaptive socketing of the loading component 8, while completing the automatic material stripping, the ring flattening socket assembly is realized, and centralized material swinging is realized. Multiple groups of ring-mounted sheet materials are sequentially socketed in the detachable loading component 8, which greatly improves the handling and transfer of materials after subsequent stamping and forming, and the comprehensive stamping efficiency is high and the use effect is good.

[0039] In addition, by reusing the flippable punch head 3 and the automatic material stripping portion 6 in the punch head 3 that relies on damping sliding, while achieving punching, automatic material stripping and swinging, the pushing effect of the automatic material stripping portion 6 is utilized to effectively avoid the sheet material being stuck in the punch head 3 and unable to come out during punching, thereby further improving the material stripping effect.

[0040] Embodiment 2: As the loading assembly 8 completes the socketing of multiple groups of molding rings, the power unit 2 9 is started to drive the gear 2 73 to rotate, causing the rotating assembly 7 to rotate. The rotating assembly 7 drives the threaded connecting column 81 to rotate, and the loading assembly 8 rotates, driving the multiple groups of molding rings that are socketed and clamped on the outer side to rotate, so that the outer side surfaces of the molding rings rub along the fixed grinding unit 10, and the molding rings rotate and contact with the grinding block 103 to complete the grinding process.

[0041] Firstly, by utilizing the centralized collection and swinging effect of the charging assembly 8 again, the formed rings are centrally sleeved in the charging assembly 8, and the power unit 9 is used to drive the charging assembly 8 to rotate during the stamping process, and the fixed polishing units 10 on both sides are used to polish the outer side surfaces of the rotating formed rings to avoid large burrs on the edges of the annular metal after punching.

The punching ring 32 is symmetrically distributed at the upper and lower ends of the mounting sleeve 31, and the gear 34 is fixedly sleeved on the outer surface of a fixed shaft 33.

[0045] By using the punching ring 32 to punch out a plate of a specified shape and size, the gear 34 is rotated by starting the power unit 4 and the flipping control is completed. The fixed shaft 33 is installed in the mounting plate 2 through the outer bearing to maintain the stability of rotation.

[0046] Among them, the power unit 1 4 and the power unit 2 9 both include a motor and a driving gear. The motor drives the driving gear to rotate, and the power unit 1 4 drives the gear 1 34 to rotate.

[0047] The power unit 2 9 realizes rotation control, and controls the rotation of the charging assembly 8 by controlling the rotation of the rotating assembly 7, thereby realizing the rotation of the formed circular ring products for socket stacking, and cooperates with the fixed grinding parts 10 on both sides to complete relative friction, thereby completing the subsequent grinding process.

The stamping column 52 is fixedly sleeved in the mounting sleeve 31. The end face of the stamping column 52 and the outer end face of the stamping ring 32 are located in the same horizontal plane.

[0049] The auxiliary stamping part 5 is used to complete the forming of the inner ring hole of the metal ring and guide the sliding of the damping sleeve 64 to achieve sliding under damping. The automatic material stripping part 6 is pushed to move only when the sheet is punched and embedded in the punching head 3. The auxiliary stamping part 5 further provides sleeve damping after stamping to maintain the stable nesting of the formed circular ring sheet.

[0050] Among them, the middle rod 61 is movably connected to the middle block 51, the connecting plate 62 and the damping sleeve 64 are both movably connected to the outer surface of the stamping column 52, the damping sleeve 64 is fixedly connected to the connecting plate 62, and the length of the automatic material stripping part 6 is less than the length of the middle rod 61.

[0051] By controlling the length of the middle rod 61, it is ensured that the automatic material stripping part 6 has space for moving and compressing up and down, and at the same time, it is reserved for the nesting of metal rings suitable for punching, so as to ensure that the automatic material stripping part 6 moving up and down completes the material removal by pushing the material upwards, that is, the gradually nested formed ring sheet material during stamping pushes the automatic material stripping part 6 upwards, and the upper end of the automatic material stripping part 6 moving upwards is gradually inserted into the stamping ring 32, pushing the previously stamped and nested formed ring sheet material on the top upwards, and completing the automatic material stripping.

[0052] Among them, a rotating component 7 is rotatably installed at the bottom of the mounting seat 1, and the rotating component 7 includes a rotating sleeve 71, a bottom groove 72 and a gear 2 73.

The product of automatic swing stacking can be transferred in a centralized manner by disassembling the loading assembly 8. The formed circular rings of external sleeve stacking can be transferred in batches by directly disassembling and removing the loading assembly 8. The clamping plate 83 on the bottom slope adapts to the upward push of the circular product, improves the effect of sliding into the outside of the clamping plate 83, and avoids jamming.

At the upper end of the punching column 52, the hydraulic push rod 11 continues to apply pressure, and the punching ring 32 and the punching column 52 punch out the target ring downward, and the target ring is nested in the punching ring 32. As the formed target ring is pressed into the punching ring 32, the automatic stripping part 6 is pushed upward to move the upper end of the stripping rod 63 located above to be flush with the end of the top punching ring 32, and then the punching die is lifted upward, the bottom plate moves, the power part 4 is started, and the gear 34 is driven to rotate, so that the punching head 3 is turned 180 degrees and located at The upper stamping ring 32 moves downward, and the material with the target ring nested rotates upward, and the next round of stamping processing is carried out again.
