[0001] The utility model relates to the technical field of metal mold production, in particular to an adjustable punching machine for metal mold production and processing. Background Art

[0002] A punch press is a stamping press. Stamping production is mainly for plates. Through the mold, the punch press can make blanking, punching, forming, drawing, trimming, fine punching, riveting and extrusion, etc. It is widely used in various fields. The punch press is suitable for mold production and processing. However, when the existing punch press punches the mold, it is not convenient to adjust the position of the mold because the mold has a certain weight.

[0003] For example, publication number CN218693062U discloses an adjustable punch press for mold production and processing. The device can drive the second screw to rotate by rotating the turntable. The threaded ring will move along the direction of the second screw, and the placement frame will move through the limit plate to adjust the position of the mold.

[0004] The device is fixedly connected to the placement rack through a limiting plate. Although the placement position of the placement rack can be changed, the widths of different molds are not the same, and the molds need to be inserted into the placement slots of the placement rack when in use. This makes it impossible for the device to adjust and use metal molds of different sizes. In view of this, we propose an adjustable punch press for metal mold production and processing.

[0024] like Figure 1-Figure 6As shown, the utility model provides a technical solution: an adjustable punch for metal mold production and processing, comprising a punch body 1, an adjusting mechanism 2 is arranged inside the punch body 1, a mobile base 5 is arranged on the upper end surface of the punch body 1, a placement rack 6 is arranged on the upper end of the mobile base 5, an adjusting structure 3 is arranged on the upper end of the mobile base 5, the adjusting structure 3 comprises a fixed frame 31 fixedly installed on the upper end of the mobile base 5, a slide bar 32 is fixedly installed on the inner wall of the fixed frame 31, a sleeve 33 is slidably connected to the surface of the slide bar 32, a limiting cylinder 310 is fixedly installed on the side wall of the sleeve 33, a connecting cylinder 34 runs through the inside of the limiting cylinder 310, a connecting block 35 is fixedly installed on the side wall of the placement rack 6, and device grooves 36 are opened on both sides of the connecting block 35, one end of a limiting spring 37 is fixedly installed on the inner wall of the device groove 36, and a T-shaped limiting block 38 is fixedly installed on the other end of the limiting spring 37, limiting grooves 39 are opened on both sides of the inner wall of the connecting cylinder 34, and a limiting structure 4 is arranged inside the fixed frame 31.

[0025] Specifically, the adjustment structure 3 of the technical solution of the utility model includes: a fixed frame 31, a sliding rod 32, a sleeve 33, a connecting tube 34, a connecting block 35, a device groove 36, a limit spring 37, a T-shaped limit block 38, a limit groove 39, and a limit tube 310.

[0026] In one embodiment of the utility model, an adjustment structure 3 is provided to facilitate replacement and adjustment of placement racks 6 of different sizes. The user can drive the placement rack 6 to vertically adjust its position through the adjustment structure 3. The adjustment structure 3 is a prior art that has been disclosed in the original application and will not be described here. A connecting block 35 is fixedly installed on the side wall of the placement rack 6, and the connecting block 35 is detachably connected to the connecting tube 34, so that the placement rack 6 can be conveniently replaced.

[0027] When replacing, the user only needs to press the T-shaped extrusion rod 8 inward at the same time so that the T-shaped limit block 38 enters the device groove 36 by squeezing the limit spring 37, thereby releasing the limit connection between the connecting block 35 and the connecting tube 34, and then the user can directly pull out the placement rack 6 to facilitate subsequent adjustment and replacement, so that the device can be adjusted and used for metal molds of different sizes through different placement racks 6.

[0028] During installation, the user can press the two groups of T-shaped push plates 47 inward. At this time, the T-shaped push plates 47 will enter the installation grooves 36 by squeezing the limit springs 37. At this time, the T-shaped push plates 47 are all located inside the installation grooves 36 and the limit springs 37 are in a compressed state. The user then directly connects the connecting block 35 and the inside of the connecting tube 34. As the connecting block 35 moves inside the connecting tube 34, when the T-shaped push plates 47 move to the inside of the limit grooves 39, the T-shaped push plates 47 are no longer squeezed by the inner wall of the connecting tube 34. At this time, the T-shaped push plates 47 are returned to the center under the elastic force of the limit springs 37 and are engaged with the limit grooves 39, thereby completing the adjustment and use of the placement rack 6.

[0029] By setting the limiting structure 4, it is convenient to adjust the position of the placement rack 6 laterally. When adjusting the placement rack 6 for different metal molds, the user can first adjust the position of the sleeve 33. At this time, the sleeve 33 slides on the surface of the sliding rod 32, and then the connecting block 35 is directly connected to the inside of the connecting tube 34. At this time, the side wall of the connecting block 35 will contact the T-shaped push plate 47 and drive it to move inward. At this time, the T-shaped push plate 47 moves toward the inside of the limiting tube 310 and drives the cross plate 48 of its side wall to move. When the T-shaped push plate 47 moves, the return spring 410 of its side wall will be stretched. The movement of the cross plate 48 drives the two groups of guide rods 49 of the side wall to move, and then drives the hinge 46 to move. The hinge 46 includes two groups of rod bodies and a group of slide plates. One of the two groups of rod bodies is fixed to the side wall of the fixed plate 45, and the other group of rod bodies is located in the sliding mouth 44 and slides.

[0030] Therefore, when the guide rod 49 drives the hinge 46 to move, the hinge 46 moves inside the slide 44, thereby driving the two sets of L-shaped limit plates 42 to move to both sides and pass through the bayonet 411 to limit the sleeve 33. There is no need to manually lock the sleeve 33. Only the installation of the placement frame 6 is required to complete the limit locking, thereby avoiding the damage of the threaded rod used in the original application due to being punched by the punching machine, thereby improving the use effect of the device.

[0031] Please continue reading Figure 1-Figure 6The limiting structure 4 includes a slider 41 slidably connected to both sides of the inner wall of the limiting cylinder 310, an L-shaped limiting plate 42 is fixedly installed on the side wall of the slider 41, a limiting opening 43 is provided on both sides of the limiting cylinder 310, a sliding opening 44 is provided inside the L-shaped limiting plate 42, a fixing plate 45 is fixedly installed on both sides of the inner wall of the limiting cylinder 310, one end of a hinge 46 is fixedly installed on the side wall of the fixing plate 45, and the other end of the hinge 46 is slidably connected to the inner wall of the sliding opening 44, and one end of a T-shaped push plate 47 is slidably connected to the inner wall of the connecting cylinder 34, and the other end of the T-shaped push plate 47 A horizontal plate 48 is fixedly installed, and guide rods 49 are fixedly installed at both ends of the horizontal plate 48. One end of a return spring 410 is fixedly installed on both sides of the T-shaped push plate 47, and the other end of the return spring 410 is fixedly connected to the inner wall of the limiting cylinder 310. A plurality of groups of bayonet holes 411 are provided on the upper and lower sides of the fixed frame 31. The side walls of the two groups of L-shaped limiting plates 42 are connected by a tension spring 7. One end of a T-shaped extrusion rod 8 passes through the inner wall of the limiting groove 39, and the other end of the T-shaped extrusion rod 8 is fixedly installed with a limiting plate. The connecting block 35 is in contact with the side wall of the T-shaped push plate 47.

[0032] During operation, when the user needs to replace different placement racks 6 for different metal molds, the user presses the T-shaped extrusion rod 8 inwardly so that the T-shaped limit block 38 enters the inside of the device groove 36 by squeezing the limit spring 37, and then the user pulls the placement rack 6 directly outward, and then adjusts the position of the sleeve 33. At this time, the sleeve 33 slides on the surface of the slide rod 32, and then the user can press the two sets of T-shaped push plates 47 inwardly. At this time, the T-shaped push plates 47 will enter the inside of the device groove 36 by squeezing the limit spring 37, and then directly connect the connecting block 35 and the inside of the connecting tube 34. As the connecting block 35 moves inside the connecting tube 34, when the T-shaped push plate 47 moves to the inside of the limit groove 39, the T-shaped push plate 47 is no longer squeezed by the inner wall of the connecting tube 34. At this time, the T-shaped push plate 47 is Under the action of the elastic force of the limit spring 37, it returns to the center and engages with the limit groove 39. When the connecting block 35 moves, its side wall will contact the T-shaped push plate 47 and drive it to move inward. At this time, the T-shaped push plate 47 moves toward the inside of the limit cylinder 310 and drives the cross plate 48 of its side wall to move. When the T-shaped push plate 47 moves, it will also stretch the return spring 410 of its side wall, and drive the two groups of guide rods 49 of its side wall to move through the movement of the cross plate 48, thereby driving the hinge 46 to move. At this time, the hinge 46 moves inside the sliding mouth 44, thereby driving the two groups of L-shaped limit plates 42 to move to both sides and pass through the bayonet 411 to limit the sleeve 33, so that there is no need to manually lock the sleeve 33. Only the installation of the placement frame 6 is required to complete the limit locking, thereby improving the use effect of the device.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
