Description

A stamping die with die head replacement function

Technical Field

The utility model belongs to the field of stamping dies, and in particular relates to a stamping die with a die head replacement function.

Background technique

A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

A Chinese patent with application number CN202320834974.4 discloses a stamping die with a replaceable stamping die head, including a base, on which a lower die head is mounted, connection ports are provided on both sides of the lower die head, and adjustment grooves are provided on the base on both sides of the lower die head, and a bidirectional screw rod is rotatably connected between the two adjustment grooves. The utility model is provided with a base, a lower mold head, a connecting port, an adjusting groove, an adjusting block, a two-way screw, a wedge block, a connecting plate, an upper mold head, a T-bar, a pressure plate, a pull rod, a support plate, a mounting plate and a connecting groove. The disassembly is completed by rotating the two-way screw to separate the wedge block from the lower mold head, and at the same time, the T-bar is twisted to separate the pressure plate from the upper mold head. Then, the mounting plate is separated from the pull rod through the connecting groove to complete the disassembly of the upper mold head, thereby making the mold head disassembly more convenient, thereby solving the problem that the mold head is fixed with multiple screws, resulting in cumbersome disassembly and assembly, wasting time and reducing the efficiency of mold head replacement. In the stamping mold for replacing the stamping mold head in this application, the upper mold head and the lower mold head need to be replaced independently, and the upper mold head and the lower mold head are a set of molds, and a set of molds needs to be replaced each time. The upper mold head and the lower mold head need to be replaced independently, resulting in low efficiency in mold replacement.

In view of this, the present utility model is proposed.

Second clamping grooves 301 are provided on opposite sides of the upper die head 3, and the second clamping blocks 6 correspond to the second clamping grooves 301.

When the lower mold head 2 and the upper mold head 3 need to be replaced, the two-way threaded pull rod 8 is rotated to drive the two first clamping blocks 5 to slide, and the first clamping block 5 drives the second clamping block 6 to slide synchronously through the telescopic rod 7, so as to facilitate the synchronous release of the limit of the lower mold head 2 and the upper mold head 3, or the synchronous positioning of the lower mold head 2 and the upper mold head 3, so as to facilitate the rapid replacement of the lower mold head 2 and the upper mold head 3.

A U-shaped frame 9 is provided on the upper side of the base 1 of the present embodiment, and a hydraulic push rod 10 is provided on the U-shaped frame 9. The output end of the hydraulic push rod 10 passes through the U-shaped frame 9 and is fixedly connected to the upper die head mounting plate 4, so that the upper die head mounting plate 4 and the upper die head 3 can be driven to slide up and down by the hydraulic push rod 10, thereby facilitating the stamping work.

The U-shaped frame 9 of this embodiment is provided with two guide holes 11, and the upper mold head mounting plate 4 is provided with two guide rods 12, and the guide rods 12 are slidably fitted in the guide holes 11, so that the guide rods 12 are slidably fitted in the guide holes 11, thereby improving the stability of the upper mold head mounting plate 4 and the upper mold head 3 sliding up and down.

A first T-shaped slide groove 101 is provided on the base 1 of the present embodiment. The upper part of the first clamping block 5 is an L-plate structure and the lower part is a T-shaped block structure. The lower part of the first clamping block 5 is slidably fitted in the first T-shaped slide groove 101, so that the lower part of the first clamping block 5 is slidably fitted in the first T-shaped slide groove 101, thereby improving the sliding stability of the first clamping block 5 on the base 1.

Bearings 102 are embedded on both opposite sides of the base 1 of this embodiment, and the threads at both ends of the two-way threaded rod 8 are in opposite directions. The two ends of the two-way threaded rod 8 are respectively threadedly matched with the two first blocks 5. The outer sides of the ends of the two ends of the two-way threaded rod 8 are provided with smooth curved surfaces. The two ends of the two-way threaded rod 8 are respectively fixed in the two bearings 102. A turning handle 13 is provided at one end of the two-way threaded rod 8, which is convenient for improving the rotation stability of the two-way threaded rod 8 through the two bearings 102, and improving the stability of the two-way threaded rod 8 driving the two first blocks 5 to slide, so as to facilitate driving the two-way threaded rod 8 to rotate through the turning handle 13.

The upper part of the second clamping block 6 is a T-shaped block structure and the lower part is an L-shaped plate structure. The upper part of the second clamping block 6 is slidably fitted in the second T-shaped slide groove 401, which facilitates the sliding fit of the upper part of the second clamping block 6 in the second T-shaped slide groove 401, thereby improving the stability of the second clamping block 6 sliding at the bottom end of the upper mold head mounting plate 4.

The telescopic rod 7 of this embodiment includes a guide cylinder 701 installed on the first card block 5 and a guide column 702 installed at the bottom end of the second card block 6, and the guide column 702 is slidably fitted in the guide cylinder 701, so that the first card block 5 and the second card block 6 can slide horizontally synchronously through the telescopic rod 7, and the guide column 702 can slide in the guide cylinder 701 to adapt to the downward sliding of the first card block 5.

Working principle: When the lower mold head 2 and the upper mold head 3 need to be replaced, the two first clamping blocks 5 are driven to separate by turning the bidirectional threaded pull rod 8 through the turning handle 13, and the limit on the lower mold head 2 is released. The first clamping block 5 drives the second clamping block 6 to slide synchronously through the telescopic rod 7, and the two second clamping blocks 6 are separated to release the limit on the upper mold head 3, thereby facilitating the synchronous release of the limit of the lower mold head 2 and the upper mold head 3, and facilitating the disassembly efficiency of the lower mold head 2 and the upper mold head 3, and then the new lower mold head 2 is placed between the two first clamping blocks 5. In the process, the upper mold head 3 is manually dragged between the two second clamping blocks 6, and then the bidirectional threaded pull rod 8 is rotated by the turning handle 13 to drive one end of the two first clamping blocks 5 to be inserted into the first clamping groove 201 on the lower mold head 2, and the lower mold head 2 is positioned. The first clamping block 5 drives the second clamping block 6 to slide synchronously through the telescopic rod 7, and the upper mold head 3 at one end of the second clamping block 6 is inserted into the second clamping groove 301 to limit the upper mold head 3, so as to facilitate the rapid installation of the lower mold head 2 and the upper mold head 3, and to facilitate the rapid replacement of the lower mold head 2 and the upper mold head 3.
