Description

Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a plate punching die. Background Art

[0002] In the existing sheet punching equipment, the lower punch is mostly fixed, and a fixed cavity is opened on the lower punch. The upper punch is provided with two pieces, a flattening piece for flattening the sheet, and a stamping piece for punching and forming. When the sheet is placed on the lower punch, the upper punch located directly above is ready to punch downward. At this time, the flattening piece first moves downward to press the sheet to fit on the lower punch, and then the stamping piece punches the sheet through the punching column extending into the flattening piece. After the punching is completed, the stamping piece is lifted, and then the flattening piece is lifted again, and the sheet can be taken out. However, when punching multiple holes in a long plate, due to the long sheet, it is often difficult to quickly switch between the fixed sheet and the movable sheet, resulting in low efficiency in long plate punching.

[0003] The patent with application number 202321764247.1 discloses a plate punching die. It includes a bottom die, the upper part of the bottom die is fixedly connected with a column, the top of the column is fixedly connected with a top plate, a cylinder is arranged on the top plate, a pressure plate is sleeved on the piston rod of the cylinder, a support plate is fixedly connected on the piston rod of the cylinder, a pressing spring is fixedly connected to the bottom surface of the support plate, a material trough is provided in the middle of the bottom die, a telescopic rod is provided in the material trough, a push spring is sleeved on the outer side of the telescopic rod, a push plate is fixedly connected to the top of the telescopic rod, auxiliary frames are fixedly connected on both sides of the bottom die, threaded holes are provided on the auxiliary frames, a rotating block is arranged on the auxiliary frames, and a fixed sheet is fixedly connected to the middle of the rotating block. The die can conveniently switch between fixed and mobile long plates, so as to facilitate the punching of a series of holes on the long plates.

[0004] The above technical solution uses a fixing plate threadedly inserted into the top of the auxiliary frame to clamp and fix the plate, but the end of the plate without a hole punched cannot allow the rotating block to pass through the plate, and can only fix one end of the plate. In addition, each time before punching, the rotating block needs to be unscrewed to adjust the position of the plate and then tightened again, which affects the stamping efficiency of the plate. Therefore, the present application provides a plate punching die to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a plate punching die to solve the problem that one end of the plate without a hole in the existing plate cannot allow a rotating block to pass through the plate, and only one end of the plate can be fixed, and each time before punching, the rotating block needs to be unscrewed to adjust the position of the plate and then tightened again, thereby affecting the plate punching efficiency.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a plate punching mold, comprising a base and a lifting plate slidably arranged on the top of the base, support plates are fixed at both ends of the base, adjustment grooves are provided at both ends of the support plates, plate positioning plates are slidably installed in the two adjustment grooves, the two plate positioning plates have plate positioning grooves corresponding to the top of the support plates on the side faces facing each other, and card slots are equidistantly provided on the outer walls of the two positioning plates, a positioning rod is slidably installed between the two plate positioning grooves, and card blocks that fit in the card slots are elastically installed at both ends of the positioning rod.

[0007] Optionally, a plurality of support rods are installed on the top of the base in a rectangular array, and a top plate is fixed to the top of the support rods.

[0008] Furthermore, a hydraulic rod is installed at the top end of the top plate, the bottom end of the hydraulic rod is connected to the lifting plate, and the plurality of support rods are slidably inserted in the lifting plate.

[0009] Furthermore, a screw is rotatably inserted in the adjustment groove, the screw is threadably inserted in the plate positioning plate, and one end of the screw extending out of the support plate is fixedly connected to a knob.

[0010] Furthermore, the side walls of the two plate positioning plates are both protrudingly provided with buttons, and the buttons are slidably inserted in the card slots and abut against the side walls of the card blocks.

[0011] Furthermore, both ends of the positioning rod are provided with telescopic slots, and the clamping block is embedded in the telescopic slots.

[0012] Furthermore, an elastic plate is embedded in the telescopic slot, and two ends of the elastic plate are fixedly connected to the inner wall of the telescopic slot and the clamping block respectively.

[0013] Furthermore, a punching die is fixedly mounted on the bottom end of the lifting plate, and a chip removal hole corresponding to the punching die is opened on the top end of the base.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, support plates are provided at both ends of the base, and adjustment grooves are opened at both ends of the support plates. When the plate is punched, its two ends are fitted and inserted into the plate positioning grooves on the plate positioning plate, and the screw is driven to rotate by the knob. During the rotation, the distance between the two plate positioning plates is adjusted, and the stamped plate is positioned by the positioning rod between the two plate positioning grooves, thereby improving the stability of the long plate during the punching process.

[0016] By setting slots equidistantly on the inner wall of the plate positioning groove, the elastic plates in the telescopic grooves at both ends of the positioning rod push the card blocks to be inserted into the card slots when the positioning rod is fixed, so that the positioning rod is kept in position between the two plate positioning plates, and positioning rods of different lengths are replaced when adjusting the spacing between the two plate positioning plates. After the punching process, a button is squeezed from the outer wall of the plate positioning plate, and the button pushes the card block to move out of the card slot, and after moving out, the two ends of the positioning rod slide in the plate positioning groove, so as to adjust the position of the positioning rod and the punching plate, and after the adjustment, the card blocks are inserted into the card slots at different positions to adjust the punching position of the long plate, thereby improving the convenience of punching positioning at different positions of the long plate.
