Description

Technical Field

[0001] The utility model relates to a die produced by combining a progressive die and a transfer die, belonging to the technical field of die. Background Art

[0002] A progressive die (also called a continuous die) consists of multiple stations, each of which completes different processing in sequence. A series of different stamping processes are completed in one stroke of the punch press. After one stroke is completed, the punch press feeding mechanism moves the material forward according to a fixed step distance. In this way, multiple processes can be completed on a pair of molds, generally including punching, blanking, bending, trimming, stretching, etc.

[0003] A Chinese patent application (publication number: CN207533808U) discloses a mold produced by combining a progressive die and a transfer die. Through structural optimization design, the original die that completed the blanking separately is integrated with the progressive die to complete the entire stamping process. The blanking is directly performed on the same machine tool, and then each process is completed by a mechanical clamp. Compared with existing technologies, the mold produced by the rationally designed progressive die and transfer die combination can complete multiple stamping processes on the same machine tool, reducing the turnover and repositioning process of using multiple molds, reducing the cost of the mold and the use of manual allocation, and reducing the time occupied by the punching machine. It is safer and faster, improves the utilization rate of materials, and increases production output.

[0004] Although the above patent can integrate the original die that completes the cutting with the progressive die to complete the stamping process of the entire process, cut the material directly on the same machine tool, and then complete each process through mechanical clamps, the die that completes the cutting will wear out during repeated use. Wear will cause the mold accuracy to decrease and affect product quality. These problems will affect the product qualification rate. The above patent is not conducive to replacing the die that completes the cutting, making the replacement process time-consuming and labor-intensive, increasing downtime, and may lead to low production efficiency.

[0005] Therefore, a die produced by combining progressive die and transfer die is proposed. Utility Model Content

[0030] The workpiece can be cut by the cooperation of the tool 9 and the cutting die 10. When the worn cutting die 10 needs to be replaced, the cutting die 10 can be quickly disassembled and installed by setting up the replacement mechanism 2, which greatly shortens the replacement time of the cutting die 10. The disassembly and assembly of the cutting die 10 can be completed in a short time, reducing downtime and speeding up production progress.

[0031] Example 2

[0032] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, in one embodiment, a buffer assembly 11 is provided on the top of the progressive upper die 7 and the transfer upper die 8, and the buffer assembly 11 includes a slide bar 1101, and the slide bar 1101 is fixedly connected to the top of the progressive upper die 7 and the transfer upper die 8, and the top of the slide bar 1101 is fixedly connected to a reset plate 1103, and the bottom of the reset plate 1103 is fixedly connected to a tension spring 1104, and the tension spring 1104 is located on the outside of the slide bar 1101, and the other end of the tension spring 1104 is fixedly connected to the top of the upper die base 6, and the top of the lower die base 3 is fixedly connected with a cylinder 14. The output end of the cylinder 14 is fixedly connected to the bottom of the upper die base 6, and the top of the fixed block 207 is fixedly connected to the bottom of the upper die base 6. A shift rod 210 is fixedly connected, and shift grooves 211 are provided on the left and right sides of the top of the lower mold base 3. The top of the shift rod 210 passes through the inner cavity of the shift groove 211 and extends out of the outside of the mounting groove 204. The rear side of the fixed block 207 is fixedly connected with a slider 12, and a slide groove 13 is provided on the rear side of the inner cavity of the mounting groove 204. The rear side of the slide groove 13 is slidably connected to the inner cavity of the slide groove 13. A slot hole 1102 is provided on the top of the upper mold base 6, and the outer side of the slide rod 1101 is slidably connected to the inner cavity of the slot hole 1102. Mechanical grippers 15 are provided on the left and right sides of the top of the workbench 1. The mechanical grippers 15 are used to place the workpiece on the mold of the next sequence to perform the work content of the next sequence.

[0033] By setting up the buffer component 11, a buffering effect can be played when the upper die base 6 and the progressive upper die 7 come into contact with the progressive lower die 4 and the transfer lower die 5. By setting up the cylinder 14, the upper die base 6 can be driven to move by the cylinder 14. By setting up the shift rod 210 and the shift groove 211, the fixed block 207 can be driven to move by the shift rod 210. The shift groove 211 can limit the movement of the shift rod 210 to prevent the shift rod 210 from offsetting during the movement. By setting up the slider 12 and the slide groove 13, the stability of the fixed block 207 during the movement can be improved. By setting up the mechanical clamp 15, the workpiece can be delivered to the next mold by the mechanical clamp 15 to complete multiple processes.

[0034] When the utility model is working: first, the upper die base 6 is driven to descend by the output end of the cylinder 14, so that the upper die base 6 drives the progressive upper die 7, the transfer upper die 8, the tool 9 and the buffer assembly 11 to descend at the same time, and when the upper die base 6, the progressive upper die 7 are in contact with the progressive lower die 4 and the transfer lower die 5, the progressive upper die 7 and the transfer upper die 8 drive the slide bar 1101 to slide in the inner cavity of the slot 1102, so that the slide bar 1101 drives the reset plate 1103 to rise, and stretches the tension spring 1104, so that the tension spring 1104 is deformed to play a buffering role, and the workpiece is cut by the cooperation of the tool 9 and the cutting die 10, and then the workpiece is delivered to the next die through the mechanical clamp 15 to complete multiple processes;

[0035] When the worn cutting die 10 needs to be replaced, the lever 210 is toggled, so that the lever 210 drives the fixing block 207 to move outward, so that the fixing block 207 squeezes the telescopic rod 205 and the return spring 206, so that the telescopic rod 205 is compressed, and the return spring 206 is deformed, which drives the limiting rod 208 to disengage from the inner cavity of the limiting hole 202, and pulls the cutting die 10 upward, so that the cutting die 10 drives the inserting block 201 to disengage from the inner cavity of the slot 203, and the cutting die 10 is disassembled;

[0036] When the cutting die 10 needs to be installed, the lever 210 is toggled so that the lever 210 drives the fixed block 207 to move outward, so that the fixed block 207 squeezes the telescopic rod 205 and the return spring 206, compresses the telescopic rod 205, and deforms the return spring 206, driving the limit rod 208 to move outward, and the cutting die 10 is clamped to the inner cavity of the slot 203 through the insert block 201. The lever 210 is released, and the return spring 206 is deformed again due to the loss of force, driving the fixed block 207 to move inward, so that the fixed block 207 drives the limit rod 208 to pass through the inner cavity of the through hole 209 and plug into the inner cavity of the limit hole 202, completing the installation of the cutting die 10, greatly shortening the replacement time of the cutting die 10.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
