Description

Technical Field

[0001] This utility model relates to the field of metal stamping die technology, specifically to a wear-resistant metal stamping die structure. Background Technology

[0002] Metal stamping dies are core equipment in the metal processing industry. They apply pressure to metal sheets to achieve forming through the cooperation of punches and dies. In existing technologies, wear resistance is usually improved by spraying wear-resistant coatings on the working surface of the die or by using high-strength alloy materials to make the die body.

[0003] Based on the above, the inventors have discovered the following problems: When using the current wear-resistant metal stamping die structure, the die changing process for stamping parts of different specifications is complicated, requiring the disassembly of multiple connecting parts, resulting in excessive downtime and affecting production efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a wear-resistant metal stamping die structure in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant metal stamping die structure to solve the problem mentioned in the background art that the current wear-resistant metal stamping die structure has a complicated die-changing process for stamping parts of different specifications, requires the disassembly of multiple connecting parts, resulting in excessive downtime and affecting production efficiency.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A wear-resistant metal stamping die structure includes a lower die base, an upper die base at the top of the lower die base, a punch fixedly mounted at the bottom of the upper die base, a die cavity adapted to the punch at the top of the lower die base, sliding holes at the four corners of the top of the lower die base, limit posts slidably connected to the inner side of the sliding holes, and springs sleeved on the outer side of the limit posts, limit grooves at the four corners of the bottom of the upper die base, the tops of the limit posts and the inner tops of the limit grooves being fixedly connected, bases on both sides of the bottom of the lower die base, positioning seats mounted at the top of the bases, positioning grooves at the top of the positioning seats, positioning rods mounted on both sides of the lower die base, the outer side of the positioning rods engaging with the inner side of the positioning grooves, a limit frame on one side of the top of the positioning seat, and a pair of flipping mechanisms for flipping the limit frame mounted on one end face of the positioning seat.

[0007] Furthermore, the tilting mechanism includes a fixed base, one end of which is fixedly connected to the top end of the positioning base. A rotating shaft is rotatably connected to the inner side of the fixed base, and a movable base is fixedly installed on the outer side of the rotating shaft. One end of the movable base is fixedly connected to the end face of the limiting frame.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the fixed seat in the flipping mechanism is fixed to the top of the positioning seat, providing stable support for the rotating shaft; the rotating shaft cooperates with the movable seat to drive the limit frame to flip around the fixed seat, thereby realizing the quick limiting or unlocking of the positioning rod by the limit frame.

[0009] Furthermore, a torsion spring is installed on the inner side of the fixing base, and one end of the torsion spring is fixedly connected to the outer side of the rotating shaft.

[0010] The beneficial effect of adopting the above-mentioned further solution is that by fixing the torsion spring on the inner side of the fixed seat to the rotating shaft, the elastic force of the torsion spring in the natural state drives the rotating shaft to rotate, so that the limit frame automatically fits the positioning seat, ensuring that the limit frame always remains fixed and preventing the limit frame from loosening due to stamping vibration.

[0011] Furthermore, the positioning rod is cylindrical.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the cylindrical positioning rod reduces the friction area with the inner side of the positioning groove, thereby reducing wear when installing or removing the lower mold base.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by engaging the locking bolt on the other end face of the limit frame with the threaded hole of the positioning seat, the flipped limit frame is firmly fixed, preventing the limit frame from loosening due to stamping vibration.

[0015] Furthermore, the top end of the spring contacts the inner top end of the limiting groove, and the bottom end of the spring contacts the top end of the lower mold base.

[0016] The beneficial effect of adopting the above-mentioned further solution is that, by having the top end of the spring contact the top end of the limiting groove and the bottom end contact the top end of the lower mold base, the two ends of the spring apply buffering force to the limiting groove and the lower mold base respectively when the mold opens and closes, thereby reducing the direct impact between the upper mold base and the lower mold base.

[0017] Furthermore, fixing holes are provided on both sides of the top of the base.

[0018] The advantage of adopting the above-mentioned further solution is that the base can be firmly fixed to the stamping equipment or the ground by bolts through the fixing holes on both sides of the top of the base, so as to avoid the base shifting and causing the mold to shift during stamping.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This wear-resistant metal stamping die structure, through the cooperation of the lower die base and the upper die base, builds the main frame of the stamping die, providing an installation foundation for the punch and die; through the matching of the punch and die, precise stamping of metal materials is achieved, and the high hardness of the die reduces wear during stamping; through the sliding hole at the top of the lower die base and the sliding cooperation of the limiting post, the upper die base is guided to open and close in the vertical direction, avoiding wear caused by die misalignment; through the spring on the outside of the limiting post, the upper die base is automatically reset after stamping, reducing manual reset operation. This invention effectively achieves precise mold positioning, stable stamping, and wear protection, extending the mold's service life and possessing high practical value. It also buffers the impact of opening and closing, reducing component wear. The top of the limiting post is fixed to the limiting groove of the upper mold base, further ensuring the stability of the mold's opening and closing trajectory. The base and positioning seat cooperate to support the lower mold base, improving overall stability. The positioning rod engages with the positioning groove, achieving precise positioning of the lower mold base and preventing mold displacement during stamping. The flipping mechanism drives the limiting frame to flip, providing secondary fixation of the lower mold base and preventing lateral displacement. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a wear-resistant metal stamping die structure, including a lower die base 1, an upper die base 2 at the top of the lower die base 1, a punch 201 fixedly installed at the bottom of the upper die base 2, a die cavity 101 adapted to the punch 201 at the top of the lower die base 1, sliding holes 102 at the four corners of the top of the lower die base 1, limit posts 3 slidably connected to the inner side of the sliding holes 102, springs 4 sleeved on the outer side of the limit posts 3, and limit grooves 2 at the four corners of the bottom of the upper die base 2. 02. The top of the limiting post 3 is fixedly connected to the inner top of the limiting groove 202. Bases 5 are provided on both sides of the bottom end of the lower mold base 1. A positioning seat 7 is installed on the top of the base 5. A positioning groove 701 is opened on the top of the positioning seat 7. Positioning rods 6 are installed on both sides of the lower mold base 1. The outer side of the positioning rod 6 is engaged with the inner side of the positioning groove 701. A limiting frame 9 is provided on one side of the top of the positioning seat 7. A pair of flipping mechanisms 8 for flipping the limiting frame 9 are installed on the top of one end face of the positioning seat 7. The lower mold base... The lower die base 1, in conjunction with the upper die base 2, forms the main frame of the stamping die, providing a mounting base for the punch 201 and the die 101. The punch 201 and die 101 are matched to achieve precise stamping of metal materials, while the high hardness of the die reduces wear during stamping. The upper die base 2 is guided to open and close vertically by sliding the sliding hole 102 at the top of the lower die base 1 and slidingly engaging with the limiting post 3, preventing die misalignment and wear. The spring 4 on the outside of the limiting post 3 automatically resets the upper die base 2 after stamping, reducing manual reset operations and buffering the opening and closing impact, thus reducing component wear. The limiting post 3 is fixed to the limiting groove 202 of the upper die base 2, further ensuring the stability of the die opening and closing trajectory. The lower die base 1 is supported by the base 5 and the positioning seat 7, improving overall stability. The positioning rod 6 engages with the positioning groove 701, achieving precise positioning of the lower die base 1 and preventing die displacement during stamping. The flipping mechanism 8 drives the limiting frame 9 to flip, providing secondary fixation for the lower die base 1 and preventing lateral displacement.

[0024] The flipping mechanism 8 includes a fixed seat 801, one end of which is fixedly connected to the top end of the positioning seat 7. A rotating shaft 802 is rotatably connected to the inner side of the fixed seat 801, and a movable seat 803 is fixedly installed on the outer side of the rotating shaft 802. One end of the movable seat 803 is fixedly connected to the top end of the limiting frame 9. The fixed seat 801 in the flipping mechanism 8 is fixed to the top end of the positioning seat 7, providing stable support for the rotating shaft 802. Through the cooperation of the rotating shaft 802 and the movable seat 803, the limiting frame 9 is driven to flip around the fixed seat 801, so as to realize the quick limiting or unlocking of the positioning rod 6 by the limiting frame 9.

[0025] The inner side of the fixed seat 801 is equipped with a torsion spring 804. One end of the torsion spring 804 is fixedly connected to the outer side of the rotating shaft 802. The torsion spring 804 on the inner side of the fixed seat 801 is fixed to the rotating shaft 802. Under natural conditions, the elastic force of the torsion spring 804 drives the rotating shaft 802 to rotate, so that the limit frame 9 automatically fits into the positioning seat 7, ensuring that the limit frame 9 always remains fixed and preventing the limit frame 9 from loosening due to stamping vibration.

[0026] The positioning rod 6 is cylindrical. The cylindrical positioning rod 6 reduces the friction area with the inner side of the positioning groove 701, thereby reducing wear when installing or removing the lower mold base 1.

[0027] The other end face of the limiting frame 9 is equipped with a locking bolt 10, and the bottom end of one end face of the positioning seat 7 is provided with a threaded hole. One end of the locking bolt 10 engages with the inner side of the threaded hole. By engaging the locking bolt 10 on the other end face of the limiting frame 9 with the threaded hole of the positioning seat 7, the flipped limiting frame 9 is firmly fixed to prevent the limiting frame 9 from loosening due to stamping vibration.

[0028] The top end of the spring 4 contacts the inner top end of the limiting groove 202, and the bottom end of the spring 4 contacts the top end of the lower mold base 1. By having the top end of the spring 4 contact the top end of the limiting groove 202 and the bottom end contact the top end of the lower mold base 1, the two ends of the spring 4 apply buffering force to the limiting groove 202 and the lower mold base 1 respectively when the mold opens and closes, thereby reducing the direct impact between the upper mold base 2 and the lower mold base 1.

[0029] The base 5 has fixing holes 501 on both sides of its top end. The base 5 can be firmly fixed to the stamping equipment or the ground by bolts through the fixing holes 501 on both sides of its top end, so as to prevent the base 5 from shifting and causing the mold to shift during stamping.

[0030] Specifically, the working principle of this wear-resistant metal stamping die structure is as follows: During use, the lower die holder 1 and upper die holder 2 cooperate to construct the main frame of the stamping die, providing an installation base for the punch 201 and die 101; the matching of the punch 201 and die 101 enables precise stamping of metal materials, while the high hardness of the die reduces wear during stamping; the sliding hole 102 at the top of the lower die holder 1 slides with the limiting post 3, guiding the upper die holder 2 to open and close vertically, preventing die misalignment and wear; the spring 4 on the outside of the limiting post 3 pushes the upper die holder 2 to automatically reset after stamping, reducing manual reset operations. The mechanism buffers the impact of opening and closing, reducing component wear; the top of the limiting post 3 is fixed to the limiting groove 202 of the upper mold base 2, further ensuring the stability of the mold opening and closing trajectory; the base 5 and the positioning seat 7 cooperate to support the lower mold base 1, improving overall stability; the positioning rod 6 engages with the positioning groove 701 to achieve precise positioning of the lower mold base 1, preventing mold displacement during stamping; the flipping mechanism 8 drives the limiting frame 9 to flip, providing secondary fixation for the lower mold base 1 and preventing lateral displacement; the fixed seat 801 in the flipping mechanism 8 is fixed to the top of the positioning seat 7, providing stable support for the rotating shaft 802; the rotating shaft 802 cooperates with the movable seat 803 to carry... The movable limit frame 9 rotates around the fixed base 801, enabling the limit frame 9 to quickly limit or unlock the positioning rod 6. It is fixed to the rotating shaft 802 via a torsion spring 804 inside the fixed base 801. In its natural state, the elastic force of the torsion spring 804 drives the rotating shaft 802 to rotate, causing the limit frame 9 to automatically conform to the positioning base 7, ensuring that the limit frame 9 remains fixed and preventing loosening due to stamping vibration. The cylindrical positioning rod 6 reduces the friction area with the inner side of the positioning groove 701, reducing wear during the installation or removal of the lower mold base 1. The locking bolt 10 on the other end of the limit frame 9 engages with the threaded hole of the positioning base 7, allowing the rotated frame to engage with the positioning rod 6. The limiting frame 9 is firmly fixed to prevent the limiting frame 9 from loosening due to stamping vibration. The top end of the spring 4 contacts the top end of the limiting groove 202 and the bottom end contacts the top end of the lower mold base 1. When the mold opens and closes, the two ends of the spring 4 apply buffer force to the limiting groove 202 and the lower mold base 1 respectively, reducing the direct impact between the upper mold base 2 and the lower mold base 1. Through the fixing holes 501 on both sides of the top end of the base 5, the base 5 is firmly fixed to the stamping equipment or the ground with bolts to prevent the base 5 from shifting and causing the mold to shift during stamping. This utility model can effectively achieve precise positioning of the mold, stable stamping and wear protection, and extend the service life of the mold, and has high practical value.
