Description

Technical Field

[0001] The invention belongs to the technical field of stamping equipment, and in particular relates 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 circular parts on mining equipment, it is especially 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 onto the work surface. For the target plate formed after punching, special material removal and stripping processes are required, especially for the forming of annular plates. Since both the outer and inner sides have sufficient punching contact areas, 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 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 surface 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

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts 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 base 1, a mounting plate 2 is movably sleeved inside the mounting base 1, a punching head 3 is provided at the bottom of the mounting base 1, the punching head 3 is rotatably mounted between the mounting plates 2 on both sides, an auxiliary punching part 5 is fixedly sleeved inside the punching head 3, an automatic material stripping part 6 is slidably installed inside the punching head 3, a charging assembly 8 is rotatably provided at the bottom of the mounting base 1, fixed grinding parts 10 are fixedly provided on both sides of the charging assembly 8, a power part 1 4 is fixedly provided on the side of the mounting plate 2, the power part 1 4 controls the flipping of the punching head 3, and a power part 2 9 is provided at the bottom of the mounting base 1.

[0034] The automatic material stripping part 6 includes an intermediate rod 61, a connecting plate 62, a material stripping 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 stripping 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 plate 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, ensuring stability during the flipping action.

[0037] Example 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 punching head 3 downward to keep the sheet to be stamped below the stamping die. As the punching ring 32 in the punching head 3 and the punching column 52 in the auxiliary punching part 5 contact the top of the sheet, the spring 13 is further compressed in the tightening state, causing the mounting seat 1 and the loading assembly 8 to continue to move downward. The connecting column 81 in the loading assembly 8 presses against the upper end of the punching column 52 in the auxiliary punching part 5. 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. Until it is flush with the end of the top stamping ring 32, then the stamping die is lifted upward, the bottom plate moves, the power unit 4 is started, and the gear 34 is driven to rotate, so that the punch head 3 flips 180 degrees, and the stamping ring 32 located above moves to the bottom, and the material with the nested target ring rotates to the top, and the next round of stamping is carried out again. As the bottom molded ring is punched and nested in the stamping ring 32, the internal automatic material stripping part 6 is synchronously pushed upward, and at the same time, the top nested molded ring is pushed upward. During the pushing process, the top molded ring is directly inserted upward into the outer surface of the charging assembly 8, and while squeezing the clamping plate 83 from the bottom, it is stably sleeved on the outside of the clamping plate 83. Then the stamping die moves upward again to reset and rotate, completing the automatic stripping and swinging of the molded ring after stamping.

[0038] First, by using the reversible punch head 3 and cooperating with the automatic stripping part 6 with internal sliding sleeve, after the stamping 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 stripping part 6 is automatically pushed upward when the stamping occurs, so that the previously stamped formed ring is ejected upward during the stamping, and the charging component 8 adapted to the top during the stamping process is cooperated to push the top formed and nested ring product upward to the charging component while stamping. 8, completes automatic material stripping, and comes out of the punching 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 socketing assembly of the ring is realized, and the centralized material swing 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 punching head 3 and the automatic material stripping part 6 in the punching head 3 that relies on damping sliding, while achieving punching, automatic material stripping and swinging, the pushing effect of the automatic material stripping part 6 is utilized to effectively avoid the sheet material being stuck in the punching head 3 and unable to come out during punching, thereby further improving the material stripping effect.

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

[0041] First, by reusing the centralized collection and swinging effect of the charging assembly 8, the formed rings are centrally sleeved in the charging assembly 8, and the power unit 2 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 surface of the rotating formed ring to avoid large burrs on the edge of the ring metal after punching. After the stamping is completed, the stacking and polishing are automatically completed, and the application prospects are good.

[0042] Among them, a side plate 12 is fixedly connected to the side of the mounting plate 2, and a spring 13 is fixedly connected between the side plate 12 and the mounting seat 1.

[0043] By utilizing the connection of the side plate 12 to support the spring 13 and utilizing the elasticity of the spring 13, it is ensured that the punch head 3 contacts the plate first and the position of the punch head 3 and the charging assembly 8 is further adjusted to ensure that the stable socketing of the formed circular ring product can be achieved upward.

[0044] Among them, the punching head 3 includes a mounting sleeve 31, a punching ring 32, a fixed shaft 33 and a gear 1 34.

The punching ring 32 is symmetrically distributed at the upper and lower ends of the mounting sleeve 31, and the gear 1 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 specified shape and size, the gear 1 34 is rotated by starting the power unit 1 4 and the flip 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 of the socket stacking, and cooperates with the fixed grinding parts 10 on both sides to complete relative friction, thereby completing the subsequent grinding process.

[0048] Among them, the auxiliary stamping part 5 includes an intermediate block 51 and a stamping column 52. The intermediate block 51 is fixedly sleeved in the mounting sleeve 31, and the stamping column 52 is fixedly sleeved in the mounting sleeve 31.

[0049] The auxiliary punching 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 plate is punched and embedded in the punching head 3. The auxiliary punching part 5 further provides sleeve damping after punching to maintain the stable nesting of the formed ring plate.

[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 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 movement and compression up and down, and at the same time, it reserves the nesting of the metal rings adapted for punching, so as to ensure that the automatic material stripping part 6 moving up and down completes the material pushing upward to remove the material, that is, the gradually nested formed ring sheet material during stamping pushes the automatic material stripping part 6 upward to move upward, and the upper end of the automatic material stripping part 6 moving upward is gradually inserted into the punching ring 32, pushing the previously punched and nested formed ring sheet material on the top upward to complete the automatic material stripping.

[0052] Among them, the bottom of the mounting base 1 is rotatably installed with a rotating component 7, which includes a rotating sleeve 71, a bottom groove 72 and a gear 2 73. The bottom of the mounting base 1 is opened and closed with an assembly cavity 14. The rotating sleeve 71 is rotatably sleeved in the assembly cavity 14 through a retaining ring on the outer side. The bottom groove 72 is opened at the bottom of the rotating sleeve 71. The gear 2 73 is fixedly sleeved on the outer surface of the rotating sleeve 71. The power unit 2 9 drives the gear 2 73 to rotate. The upper end of the connecting column 81 is threadedly sleeved in the bottom groove 72. The side groove 82 is opened on the outer surface of the connecting column 81. One end of the spring 2 84 is fixed in the side groove 82, and the other end is fixedly connected to the clamping plate 83. The bottom of the clamping plate 83 is provided with an inclined surface.

[0053] The bottom groove 72 is provided with a thread inside to adapt to the installation of the connecting column 81. It can be disassembled to realize the centralized transfer of the automatically swinging and stacking products. The loading component 8 can be directly disassembled and removed to transfer the formed circular rings of the external sleeve stacking in batches. 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.

[0055] The fixed grinding part 10 is adapted to the outer side of the punched circular product to achieve outer side grinding. The elastic pad 102 has a slight elasticity to ensure that the grinding block 103 fully contacts the fixed circular product to complete the grinding of the punched circular product.

[0056] The working principle and use process of the present invention are as follows: During the stamping process, the hydraulic push rod 11 installed and fixed on the external stamping equipment moves, pushing the mounting seat 1 and the punching head 3 to move downward, keeping the sheet to be stamped located below the stamping die, as the punching ring 32 in the punching head 3 and the punching column 52 in the auxiliary punching part 5 contact the top of the sheet, the spring 13 is further compressed in the first pressing state, causing the mounting seat 1 and the charging assembly 8 to continue to move downward, and the connecting column 81 in the charging assembly 8 presses against the auxiliary punching part 5. 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. Then the punching die is lifted upward, the bottom plate moves, the power part 14 is started, and the gear 1 34 is driven to rotate, so that the punching head 3 is turned 180 degrees and is 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.
