Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a stamping die with a replaceable stamping die head. Background Technology

[0002] A replaceable stamping die head is a metal processing equipment that enables quick replacement of punch components through modular design. Its core function is to meet the needs of multi-variety, small-batch production through standardized interfaces and flexible configuration, while reducing downtime maintenance costs.

[0003] Traditional stamping dies typically consist of two parts, upper and lower, which are directly mounted on the stamping equipment. However, this type of die usually has a large overall structure. When replacement is needed, the entire die needs to be disassembled. The weight of the entire die makes disassembly very inconvenient, and damage to the stamping surface can render the entire die unusable, increasing the cost of use. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping die with a replaceable stamping die head. By setting a fixing mechanism, specifically positioning the stamping die head on top of the die base, and rotating the double-ended threaded rod together with the handle, the two extrusion blocks move away from each other, causing the extrusion blocks to press against the inclined surface of the bottom groove, quickly fixing the stamping die head. By rotating the handle counterclockwise, the two extrusion blocks move closer together, allowing the stamping die head to be disassembled individually. This split design not only reduces weight and facilitates subsequent replacement, but also reduces replacement costs when the stamping surface of the stamping die head is damaged. It solves the problem that traditional stamping dies typically consist of two parts, upper and lower, directly mounted on the stamping equipment. However, this type of die usually has a large overall structure, requiring the entire die to be disassembled for replacement. The weight of the entire die is not only inconvenient to disassemble, but also leads to the entire die being scrapped and increasing usage costs when the stamping surface is damaged.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a stamping die with a replaceable stamping die head, including a die base, on the top of which a stamping die head is positioned, and T-shaped sliders are provided at the four corners of the bottom of the die base. The stamping die head has a bottom groove, and also includes: A fixing mechanism is provided inside the mold base. The fixing mechanism includes two extrusion blocks symmetrically arranged inside the mold base. A double-ended threaded rod is threadedly connected to the center of the extrusion block. Two sliding rods are slidably connected inside the extrusion block. A throttle handle is fixedly connected to the left and right sides of the double-ended threaded rod. Both ends of the double-ended threaded rod penetrate the mold base and extend to the outside. The double-ended threaded rod is rotatably connected to the mold base. The top of the extrusion block is protruding, and the bottom of the protrusion is sloped. The left and right sides of the inner wall of the bottom groove are also sloped. The slope of the protrusion on the top of the extrusion block matches the slope on the inner wall of the bottom groove.

[0006] Furthermore, the slide bar slides through the extrusion block and extends to the outside. The left and right ends of the slide bar are fixedly connected to the inner wall of the mold base. The top left and right sides of the mold base are threaded with locking bolts. The bottom of the locking bolts contacts the outer surface of the double-ended threaded rod. The locking bolts are used to lock and fix the double-ended threaded rod to prevent it from becoming loose.

[0007] Furthermore, the stamping die head is provided with connecting plates on both the front and back sides. Two I-shaped inserts are fixedly connected to the side of the connecting plates facing the stamping die head. The die base and the stamping die head are provided with two T-shaped slots on both the front and back sides. Magnetic blocks are embedded in both the die base and the front and back sides of the stamping die head. The T-shaped slots on the stamping die head correspond to the T-shaped slots on the die base. The I-shaped inserts are positioned and inserted into the T-shaped slots. After the connecting plate is inserted into the T-shaped slot through the I-shaped inserts, the magnetic blocks are used to attract and fix the connecting plate, thereby ensuring the stability of the I-shaped inserts after installation.

[0008] Furthermore, positioning holes are provided at the four corners of the bottom of the stamping die head, and positioning shafts are fixedly connected to the four corners of the top of the die base. The bottom of the stamping die head is positioned and inserted into the positioning shaft through the positioning hole. The stamping die head is positioned and placed by inserting it into the positioning shaft at the top of the die base through the positioning hole at the bottom.

[0009] Furthermore, the bottom of the stamping die head contacts the top of the die base, and the four corners of the die base are threadedly connected to the T-shaped slider by bolts. The stamping die head has grooves on both the left and right sides. The die base can be installed on the worktable of the stamping equipment by the T-shaped slider and can be installed on the execution structure of the stamping equipment by bolts. When the stamping die head is released from its fixed position, it can be disassembled by lifting the stamping die head upward through the grooves.

[0010] This utility model has the following beneficial effects: 1. This utility model uses a fixing mechanism to position the stamping die head on the top of the die base. By rotating the handle together with the double-ended threaded rod, the two extrusion blocks move away from each other, causing the extrusion blocks to press the inclined surface of the bottom groove side, thus quickly fixing the stamping die head. By rotating the handle counterclockwise, the two extrusion blocks move closer to each other, allowing the stamping die head to be disassembled separately. This split design not only reduces weight and facilitates subsequent replacement, but also reduces replacement costs when the stamping surface of the stamping die head is damaged.

[0011] This utility model uses an I-shaped insert to fix the stamping die head on the die base. The T-slot on the stamping die head corresponds to the T-slot on the die base. The connecting plate is then inserted into the T-slot through the I-shaped insert to fix the stamping die head on the die base. This method is particularly useful when installing the upper die, as it provides support and facilitates subsequent locking.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1-5 As shown, this utility model is a stamping die with a replaceable stamping die head, including a die base 1, a stamping die head 11 positioned on the top of the die base 1, T-shaped sliders 12 provided at the four corners of the bottom of the die base 1, and a bottom groove 112 formed at the bottom of the stamping die head 11, and also including: Fixing mechanism 2 is located inside the mold base 1. Fixing mechanism 2 includes two symmetrically arranged extrusion blocks 21 inside the mold base 1. A double-ended threaded rod 22 is threadedly connected to the center of each extrusion block 21. Two sliding rods 23 are slidably connected inside each extrusion block 21. A handle 221 is fixedly connected to the left and right sides of the double-ended threaded rod 22. Both ends of the double-ended threaded rod 22 penetrate the mold base 1 and extend to the outside. The double-ended threaded rod 22 is rotatably connected to the mold base 1. When the stamping die head 11 is positioned on top of the mold base 1, rotating the double-ended threaded rod 22 together with the handle 221 causes the two extrusion blocks to rotate. The blocks 21 are spaced apart, causing the extrusion block 21 to press the inclined surface of the side of the bottom groove 112, quickly fixing the stamping die head 11. By rotating the handle 221 counterclockwise, the two extrusion blocks 21 are brought closer together, and the stamping die head 11 can be disassembled separately. This method is a split setting, which not only reduces weight and facilitates subsequent replacement, but also reduces replacement costs when the stamping surface of the stamping die head 11 is damaged. The top of the extrusion block 21 is convex, and the bottom of the convex part is inclined. The left and right sides of the inner wall of the bottom groove 112 are both inclined. The inclined surface of the convex part at the top of the extrusion block 21 matches the inclined surface on the inner wall of the bottom groove 112.

[0018] The slide bar 23 slides through the extrusion block 21 and extends to the outside. The left and right ends of the slide bar 23 are fixedly connected to the inner wall of the mold base 1. The top left and right sides of the mold base 1 are threaded with locking bolts 17. The bottom of the locking bolts 17 contacts the outer surface of the double-headed threaded rod 22.

[0019] The stamping die head 11 is provided with connecting plates 13 on both the front and back sides. Two I-shaped inserts 131 are fixedly connected to the side of the connecting plates 13 facing the stamping die head 11. Two T-shaped slots 15 are provided on both the front and back sides of the die base 1 and the stamping die head 11. Magnetic blocks 14 are embedded in both the front and back sides of the die base 1 and the stamping die head 11. The T-shaped slots 15 on the stamping die head 11 correspond to the T-shaped slots 15 on the die base 1. The I-shaped inserts 131 are positioned and inserted into the T-shaped slots 15. After the stamping die head 11 is positioned on the die base 1, the T-shaped slots 15 on the stamping die head 11 correspond to the T-shaped slots 15 on the die base 1. Then, the connecting plates 13 are inserted into the T-shaped slots 15 through the I-shaped inserts 131 to restrict the stamping die head 11 on the die base 1. Especially when installing the upper die, this method can support the upper die and facilitate subsequent locking work.

[0020] The stamping die head 11 has positioning holes 113 at the four corners of its bottom, and positioning shafts 16 are fixedly connected to the four corners of the top of the die base 1. The bottom of the stamping die head 11 is positioned and inserted into the positioning shafts 16 through the positioning holes 113.

[0021] The bottom of the stamping die head 11 contacts the top of the die base 1. The four corners of the die base 1 are threadedly connected to the T-shaped slider 12 by bolts. The stamping die head 11 has grooves 111 on the left and right sides. The die base 1 can be installed on the worktable of the stamping equipment by the T-shaped slider 12, and can also be installed on the execution structure of the stamping equipment by bolts.

[0022] One specific application of this embodiment is: In use, place the mold base 1 on the worktable of the stamping machine and insert the T-shaped slider 12 into the slot of the worktable. Then, use bolts to connect and fix the mold base 1 and the T-shaped slider 12, fixing the mold base 1 on the worktable. Another mold base 1 can be bolted onto the actuator of the stamping machine, allowing the upper and lower stamping die heads 11 to be installed on the two mold bases 1 respectively. When installing the stamping die head 11, first insert the stamping die head 11 into the positioning shaft 16 at the top of the mold base 1 through the positioning hole 113 at the bottom, then install the stamping die... The die head 11 is positioned and placed, at which time the T-slot 15 on the die head 11 corresponds to the T-slot 15 on the die base 1. Then, the connecting plate 13 is inserted into the T-slot 15 through the I-shaped insert 131. The connecting plate 13 is then attracted and fixed by the magnetic attraction of the magnetic block 14, thereby ensuring the stability of the I-shaped insert 131 after installation. At this time, the I-shaped insert 131 will connect the die base 1 and the die head 11, thereby restricting the die head 11 on the die base 1. Especially when installing the upper die, this method can support the upper die and facilitate subsequent locking work. Then, turning the handle 221 clockwise causes the double-threaded rod 22 to rotate as well, causing the two extrusion blocks 21 to move away from each other and slide on the slide rod 23. This makes the movement of the extrusion blocks 21 more stable and smooth. The protrusion on the top of the extrusion block 21 contacts the inclined surface of the side of the bottom groove 112. By continuously turning the handle 221, the extrusion blocks 21 press against the inclined surface of the side of the bottom groove 112, thus making the stamping die head 11 fit tightly against the die base 1, completing the fixation. Finally, the locking bolt 1 is used. 7. Tighten the double-ended threaded rod 22 to prevent it from becoming loose. When the stamping die head 11 needs to be replaced, turn the locking bolt 17 counterclockwise to release the double-ended threaded rod 22. Then turn the handle 221 counterclockwise to disengage the two extrusion blocks 21 from the inclined surface of the bottom groove 112. Pull the connecting plate 13 to disengage the I-shaped insert 131 from the die base 1 and the stamping die head 11. Finally, lift the stamping die head 11 upward through the groove 111 for disassembly, which is convenient for subsequent replacement.
