Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a multi-channel stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It uses a die installed on a press to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired parts. There are many types of stamping dies, including blanking dies, punching dies, cutting dies, notching dies, trimming dies, cutting dies, bending dies, drawing dies, forming dies, etc. In the manufacturing process, the material selection of the stamping die is crucial. Commonly used materials include steel, cemented carbide, steel-bonded cemented carbide, zinc-based alloy, low melting point alloy, aluminum bronze, and polymer materials. The selection of these materials depends on factors such as the strength, hardness, wear resistance, and corrosion resistance of the required mold.

[0003] Among them, a multi-pass stamping die is a special stamping die, which involves multiple stamping operations at various stations arranged in a row, and each stamping operation is completed by a corresponding stamping die. This type of die is designed to achieve more efficient and accurate stamping production, especially in the manufacture of complex parts that require multi-step forming. Multi-pass stamping dies usually include key components such as punches, dies, and ejectors. The punches and dies of each stamping die are designed according to the shape and size of the part to ensure that the accurate shape and size can be obtained during the stamping process. The ejector is used to push the part out of the die after stamping for the next stamping operation.

[0004] A common multi-pass stamping die drives the stamping plate to move on the top of the bottom die through a transmission device. However, after a stamping operation, the steel plate is easily stuck on the top of the bottom die, making it difficult to demold the steel plate and thus making it difficult to move forward. In view of this, the present application proposes a multi-pass stamping die. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a multi-pass stamping die, which has the advantages of facilitating the demoulding and advancement of the steel plate, and solves the problem that after a stamping operation, the steel plate is easily stuck on the top of the bottom die, making it difficult to demould the steel plate and thus making it difficult to advance the steel plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-channel stamping die, comprising a mounting bottom plate, a mounting vertical plate fixedly mounted on the top of the mounting bottom plate, a mounting top plate fixedly mounted on the top of the mounting vertical plate, a stamping oil cylinder fixedly mounted on the bottom of the mounting top plate, an upper die fixedly mounted on the downward movable end of the stamping oil cylinder, two slide grooves are opened at the bottom of the upper die, and a demoulding guide assembly is slidably mounted inside the slide groove;

[0007] The demoulding guide assembly includes two sliders slidably installed inside the slide groove, side plates fixedly installed at the bottom of the sliders, a rotating shaft rotatably installed on the opposite sides of the two side plates, and a demoulding guide roller fixedly installed on the surface of the rotating shaft.

[0008] Furthermore, an adjustment limit assembly is provided on the inner side wall of the slide groove, and a threaded through hole is provided on one side of the slide block.

[0009] Furthermore, the adjustment limit assembly includes a double-headed screw rotatably mounted on the inner wall of the slide groove and an adjustment motor fixedly mounted on one side of the upper mold.

[0010] Furthermore, the two sliding blocks are respectively threadedly mounted on the surfaces of the double-headed screw rod near both ends, and the output shaft of the adjustment motor is fixedly connected to one end of the double-headed screw rod.

[0011] Furthermore, a bottom mold is fixedly mounted on the top of the mounting base plate, and a docking groove adapted to the demoulding guide assembly is formed on the top of the bottom mold.

[0012] Furthermore, fixed corner blocks are fixedly installed at the four corners of the bottom mold, guide rods are fixedly installed on the tops of the fixed corner blocks, and limiting plates are fixedly installed on the tops of the guide rods.

[0013] Furthermore, movable corner blocks are fixedly installed at the four corners of the upper mold, and the guide rod slides through the movable corner blocks. A punch head is fixedly installed at the bottom of the upper mold located between the two slide grooves, and a punch groove adapted to the punch head is opened on the top of the bottom mold.

[0014] Compared with the prior art, the utility model provides a multi-pass stamping die, which has the following beneficial effects:

[0015] 1. The multi-pass stamping die has a slide groove at the bottom of the upper die, and a demoulding guide assembly is slidably installed inside the slide groove. When the steel plate is placed above the demoulding guide roller, the demoulding guide roller enters the docking groove during stamping without affecting the stamping. When the steel plate moves forward, the upper die drives the demoulding guide roller to rise, driving the steel plate to separate from the bottom die. Under the action of the demoulding guide roller, the steel plate moves forward easily, thus solving the problem that after a stamping, the steel plate is easily stuck on the top of the bottom die, making it difficult to demould the steel plate and causing it to move forward.

[0016] 2. The multi-channel stamping die sets an adjustment limit assembly inside the slide slot, and drives the double-headed screw to rotate by adjusting the motor, so that the slider moves to the middle or to both sides at the same time, and changes the spacing of the side plates to adapt to steel plates of different widths, which is convenient for limiting steel plates of different widths and improving the stamping efficiency of the steel plates.

[0026] Secondly, movable corner blocks 13 are fixedly installed at the four corners of the upper die 5, and the guide rod 12 slides through the movable corner blocks 13. A punch head 14 is fixedly installed at the bottom of the upper die 5 between the two slide grooves 6, and a punching groove 15 adapted to the punch head 14 is opened on the top of the bottom die 9. The steel plate is placed on the top of the demoulding guide roller 74. During stamping, the stamping cylinder 4 drives the upper die 5 to press down, driving the punch head 14 to stamp the steel plate. At this time, the demoulding guide assembly 7 enters the docking groove 10. After the stamping is completed, the upper die 5 rises, driving the demoulding guide assembly 7 to rise, so that the demoulding guide roller 74 lifts the steel plate off the top of the bottom die 9 to complete the demoulding.
