[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be produced by mechanical processing through various mold applications.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the embodiment, Figure 1-3 A metal processing punching machine is provided, comprising a body 1, a punching mechanism 2 is arranged on the body 1, a workbench 3 is fixedly installed on the body 1 and is opposite to the punching mechanism 2, a mold 31 is arranged on the top of the workbench 3, a mounting groove 4 is opened inside the workbench 3, two relative moving mechanisms 5 are arranged inside the mounting groove 4, a limiting frame 6 is arranged on the two moving mechanisms 5, a roller assembly 7 is arranged on the limiting frame 6, placement grooves 8 are symmetrically opened on the surface of the workbench 3, and a support assembly 9 is arranged inside the placement groove 8.

[0023] Reference Figure 1-2 , wherein the moving mechanism 5 includes a rotating rod 51, the rotating rod 51 is rotatably installed inside the mounting groove 4, a main gear 52 is fixedly installed on the outer side of the rotating rod 51, a screw rod 53 which is rotatably installed inside the mounting groove 4 and is perpendicular to the rotating rod 51, a sub-gear 54 is fixedly installed on the top of the screw rod 53, the sub-gear 54 and the main gear 52 are meshed with each other, and a limit frame 6 is threadedly connected to the screw rod 53;

[0024] With the above-mentioned structural arrangement, the rotating rod 51 is twisted, and the screw rod 53 is driven to rotate through the mutually meshing main gear 52 and sub gear 54, so that the limit frame 6 moves forward and backward with the rotation of the screw rod 53, and the distance between the two limit frames 6 is adjusted according to the width of the processed plate. At the same time, the limit frames 6 that can adjust the position separately can also adjust the positions of the two limit frames 6 according to the demand for forward and backward movement during plate processing, so that the two limit frames 6 always maintain a clamping state for the plate, adapt to and clamp plates of different widths.

[0025] Reference Figure 1-3, wherein a roller groove 61 is opened on the limit frame 6, and a support frame 62 located below the roller groove 61 is fixedly installed on the limit frame 6;

[0026] Through the above-mentioned structural setting, when the limiting frame 6 fixes the plate, the supporting frame 62 and the mold are located at the same height. When the plate is placed on the top of the supporting frame 62, the plate can be kept in a horizontal state, which is convenient for subsequent processing.

[0027] Reference Figure 1-3 The roller assembly 7 includes a spring 71, the spring 71 is symmetrically installed inside the roller groove 61, the end of the spring 71 facing the outside of the roller groove 61 is connected to the first roller 72, the first roller 72 is slidably installed inside the roller groove 61, and the second roller 73 is rotatably installed on the top of the support bracket 62;

[0028] Through the above-mentioned structural setting, the position of the plate needs to be continuously moved during plate processing. When the plate needs to be moved, the plate is pushed according to the processing direction. The existence of the spring 71 allows the first roller 72 to retain a certain margin when fixing the plate, which is convenient for workers to push the plate to move with the help of the first roller 72 and the second roller 73 to adjust the processing position.

[0029] Reference Figure 1-3 , wherein the support assembly 9 includes a connecting rod 91, the connecting rod 91 is rotatably mounted on one side of the inner side of the placement slot 8, and a support frame 92 is rotatably mounted on one end of the connecting rod 91;

[0030] Through the above-mentioned structural arrangement, when the plate to be processed is too long, the support frame 92 is erected from the placement groove 8 to provide auxiliary support for the plate to be processed, so that the plate processing position remains flat.

[0031] Working principle:

[0032] The first step to implement the innovation point:

[0033] Step 1: When punching the plate, the support frame 92 is erected from the placement slot 8 to provide auxiliary support for the plate being processed so that the plate processing position remains flat;

[0034] Step 2: Then, according to the width of the plate, the rotating rod 51 is twisted, and the screw rod 53 is driven to rotate through the mutually meshing main gear 52 and the sub-gear 54, so that the limit frame 6 moves forward and backward with the rotation of the screw rod 53, and the distance between the two limit frames 6 is adjusted according to the width of the processed plate. At the same time, the limit frames 6 that can adjust the position separately can also adjust the positions of the two limit frames 6 according to the requirements of moving forward and backward during plate processing, so that the two limit frames 6 always maintain a clamping state for the plate, adapt to and clamp plates of different widths;

[0035] Step 3: After the fixation is completed, the stamping mechanism is started to process the plate. During the processing, the plate is pushed according to the processing direction. The existence of the spring 71 allows the first roller 72 to retain a certain margin when fixing the plate, which is convenient for workers to push the plate to move with the help of the first roller 72 and the second roller 73 to adjust the processing position.
