Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically a metal sheet stamping device. Background Technology

[0002] Stamping is a processing technology that uses dies and stamping equipment to apply external force to sheet metal, causing it to undergo plastic deformation or separation, thereby obtaining parts with the desired shape, size, and properties. Stamping is a cold metal forming process, also known as cold stamping or sheet metal stamping. It uses dies to deform sheet metal in stamping equipment without heating, and belongs to materials forming engineering technology.

[0003] Regarding the above and existing related technologies: when processing metal sheets, stamping is a common processing method. When using a stamping press, a die is needed to shape the sheet. Since most dies are fixed to the stamping press with bolts, and the mounting holes of most stamping presses are relatively fixed, the die base needs to be set to a specific size when fixing the die. This not only leads to material waste, but also easily causes problems such as large differences between the die mounting holes and the machine mounting positions, making it inconvenient to fix. Therefore, a metal sheet stamping device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The metal sheet stamping device of this utility model includes a machine body, a main mold, a secondary mold, and two fixing devices. A stamping part is fixedly connected to the surface of the machine body. The main mold is located directly above the machine body, and the secondary mold is located directly below the stamping part. The two fixing devices are respectively set on the surfaces of the main mold and the secondary mold. Each fixing device includes a placement plate, which is located directly above the machine body. A threaded post is threadedly connected to the inner wall of the placement plate. A fixing post is fixedly connected to the upper surface of the threaded post. A limit block is movably connected to the surface of the fixing post. The limit block is located on the surface of the main mold. A knob is threadedly connected to the surface of the fixing post. The knob is located on the surface of the limit block. Pushing the limit block causes it to rotate on the surface of the fixing post. The limit block rotates to the surface of the main mold. Then, rotating the knob causes it to rotate to the surface of the fixing post. The knob rests on the surface of the limit block. By setting up the placement plate, the threaded post, the fixing post, the limit block, and the knob, the position of the main mold can be fixed.

[0006] Preferably, the placement plate and the inner wall of the machine body are threaded together with multiple positioning pins. After the placement plate is attached to the machine body, the positioning pins are rotated to the inner wall of the placement plate and the machine body. The positioning pins can restrict the position of the placement plate.

[0007] Preferably, the surface of the placement plate has multiple threaded holes, and the surface of the threaded post is threadedly connected to the inner wall of the threaded hole of the placement plate. When the threaded post rotates, it rotates to the inner wall of the threaded hole, and the threaded hole facilitates the storage of the threaded post.

[0008] Preferably, the surface of the limiting block is provided with a sliding groove, and the inner wall of the sliding groove of the limiting block is movably connected to the surface of the fixed column. When the limiting block moves, the limiting block moves on the surface of the fixed column through the sliding groove. By providing the sliding groove, the limiting block can be easily moved on the surface of the fixed column.

[0009] Preferably, a soft pad is fixedly connected to the bottom end of the knob. The soft pad is located on the upper surface of the limiting block and is pressed against the surface of the limiting block. By setting the soft pad, the friction force when the limiting block moves can be increased.

[0010] Preferably, the placement plate is provided with limiting devices on both sides. The limiting device includes a placement block located on one side of the placement plate. The placement block and the inner wall of the placement plate are threadedly connected with two limiting pins. The inner wall of the placement block is threadedly connected with a threaded rod located on one side of the main mold. Rotating the threaded rod allows it to press against the side wall of the main mold. By setting the placement block, limiting pins, and threaded rod, the position of the main mold can be limited.

[0011] Preferably, a top plate is rotatably connected to the side wall of the threaded rod, and a limit frame is fixedly connected to the side wall of the top plate. The limit frame is sleeved on the surface of the threaded rod, the top plate rests against the side wall of the main mold, and the limit frame slides on the surface of the placement block. By setting the top plate, the contact area between the threaded rod and the main mold can be increased.

[0012] The advantages of this utility model are:

[0013] 1. When stamping metal sheets, this utility model uses multiple locating pins to fix two placement plates to suitable positions on the machine body and stamping section surfaces. Then, the main mold and auxiliary mold are respectively attached to the surfaces of the upper and lower placement plates. The fixing column is then rotated to drive the threaded column to rotate, and the threaded column rotates to the inner wall of the threaded hole on the placement plate. Then, the limiting block is pushed to slide or rotate on the surface of the fixing column through the sliding groove. After the limiting block is attached to the main mold, the knob is rotated to the surface of the fixing column. When the knob rotates, it will drive the soft pad to move and press against the surface of the limiting block. When the mounting hole on the main mold matches the threaded hole, bolts are used to fix the main mold to the placement plate. By setting the entire device, it is possible to fix main molds of different specifications, and at the same time, it can reduce the material wasted during the production of the main mold to match the mounting position. It can also use bolts to fix the main mold mounting hole to match the threaded hole, thereby increasing the adaptability of the entire device.

[0014] 2. In this utility model, after the main mold is fixed on the placement plate, the placement block is attached to the placement plate, and then the limiting pin is rotated to the inner wall of the placement block and the placement plate. Then, the threaded rod is rotated to make the threaded rod rotate on the inner wall of the placement block, the side wall of the top plate and the inner wall of the limiting frame. The threaded rod drives the top plate to move, and the top plate drives the limiting frame to slide. The limiting frame slides on the surface of the placement block, and the top plate presses against the side wall of the placement plate. By setting the entire device, the lateral position of the placement plate can be restricted, reducing the situation of the placement plate moving laterally. Attached Figure Description

The limit block 54 is located on the surface of the main mold 3. On the surface of the fixed post 53, a knob 55 is threadedly connected to the surface of the limiting block 54. During operation, the placement plate 51 is installed on the machine body 1, and then the fixed post 53 is rotated to rotate to the inner wall of the placement plate 51. Then the main mold 3 is placed on the surface of the placement plate 51, and then the limiting block 54 is pushed to rotate on the surface of the fixed post 53. The limiting block 54 rotates to the surface of the main mold 3, and then the knob 55 is rotated to rotate to the surface of the fixed post 53. The knob 55 presses against the surface of the limiting block 54. By setting the placement plate 51, threaded post 52, fixed post 53, limiting block 54 and knob 55, the position of the main mold 3 can be fixed.

[0024] The placement plate 51 and the inner wall of the body 1 are threaded together with a plurality of positioning pins 56; during operation, the positioning pins 56 are rotated to the inner wall of the placement plate 51 and the body 1, and the positioning pins 56 can restrict the position of the placement plate 51.

[0025] The surface of the placement plate 51 is provided with a plurality of threaded holes 57, and the surface of the threaded post 52 is threadedly connected to the inner wall of the threaded hole 57 of the placement plate 51. During operation, the threaded post 52 rotates to the inner wall of the threaded hole 57, and the threaded hole 57 is provided to facilitate the storage of the threaded post 52.

[0026] The surface of the limiting block 54 is provided with a sliding groove 58, and the inner wall of the sliding groove 58 of the limiting block 54 is movably connected to the surface of the fixed column 53. During operation, the limiting block 54 moves on the surface of the fixed column 53 through the sliding groove 58.

[0027] A soft pad 59 is fixedly connected to the bottom end of the knob 55, and the soft pad 59 is located on the upper surface of the limiting block 54. When working, the knob 55 drives the soft pad 59 to move, and the soft pad 59 presses against the surface of the limiting block 54. By setting the soft pad 59, the friction force of the limiting block 54 when it moves can be increased.

[0028] Both sides of the placement plate 51 are provided with limiting devices 6. The limiting device 6 includes a placement block 61, which is located on one side of the placement plate 51. The inner wall of the placement block 61 and the placement plate 51 are threadedly connected to two limiting pins 62.

After the limiting block 54 is attached to the main mold 3, the knob 55 is rotated to the surface of the fixing post 53. Rotating the knob 55 causes the soft pad 59 to move, pressing against the surface of the limiting block 54. When the mounting hole on the main mold 3 matches the threaded hole 57, bolts are used to fix the main mold 3 to the placement plate 51. This is achieved by setting the entire mounting plate... The device can fix the main mold 3 of different specifications, and also reduce the material wasted during the production of the main mold 3 to fit the installation position. It can also use bolts to fix the main mold 3 when the mounting hole matches the threaded hole 57, thereby increasing the adaptability of the whole device. After the main mold 3 is fixed on the placement plate 51, the placement block 61 is attached to the placement plate 51, and then the limiting pin 62 is rotated to the inner wall of the placement block 61 and the placement plate 51. Then, the threaded rod 63 is rotated to rotate on the inner wall of the placement block 61, the side wall of the top plate 64 and the inner wall of the limiting frame 65. The threaded rod 63 drives the top plate 64 to move, and the top plate 64 drives the limiting frame 65 to slide. The limiting frame 65 slides on the surface of the placement block 61, and the top plate 64 presses against the side wall of the placement plate 51. By setting the whole device, the lateral position of the placement plate 51 can be restricted, reducing the lateral movement of the placement plate 51.
