[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the device, the striking block moves downward under the pressure of the punching machine, and the left and right striking blocks move downward to push the cutting tongue to move to the middle, and apply pressure limit to the other tube body. At this time, the cutting tongue cuts the arc and the punch punches the hole. Punching is performed by this technology, thereby solving the problems of low efficiency and large loss of laser cutting.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A square tube side arc punching and punching forming die comprises an upper template 1, a lower template 2 and a square tube body 6. Four groups of limit rods are fixedly installed on the top of the lower template 2, and the surface of the limit rods is sleeved with a guide sleeve 3. Four groups of circular grooves are opened on the surface of the upper template 1. The guide sleeve 3 is fixed inside the circular groove, and the limit rod is inserted inside the guide sleeve 3. The bottom end of the upper template 1 is symmetrically fixed with striking blocks 9 on both sides.

[0022] Further, see Figure 2 It can be seen that a guide frame 5 is fixedly installed at the top of the lower template 2 near the edge of the front face, and a rectangular groove begins to appear on the top surface of the guide frame 5. During use, the rectangular groove is used to provide limited support for the other tube body 6, which is convenient for assisting punching and cutting.

[0023] Further, see Figure 2 It can be known that support plates are symmetrically fixedly installed on both sides of the lower template 2, and rubber 7 is installed on the surface of the support plates, fixed frames 4 are fixedly installed on the left and right sides of the top of the lower template 2, and a cutting tongue 8 is inserted inside the fixing frame 4, the cutting tongue 8 is fixedly connected to the rubber 7, and the cutting tongue 8 is movably connected to the fixing frame 4. The cutting tongue 8 can be moved by the thrust inside the fixing frame 4, so as to facilitate the limitation of the other tube body 6, and the rubber 7 has elastic deformation ability, which is convenient for assisting the cutting tongue 8 to reset.

[0024] Further, see Figure 3 and Figure 4 It can be known that a fixing plate is fixedly installed at the edge of the back side at the top of the lower template 2, and a middle module 11 is fixedly installed on the front side of the fixing plate. The square tube body 6 is sleeved on the surface of the middle module 11. During use, the middle module 11 plays the role of limiting support for the square tube body 6, which is convenient for auxiliary punching.

[0025] Further, see Figure 4 It can be known that a punch 10 and a material stripping rod 12 are fixedly mounted on the inner wall of the cutting tongue 8. During use, the other pipe can be limited by the material stripping rod.

[0026] Further, see Figure 2 It can be seen that there are two groups of striking blocks 9, and the bottom ends of the two groups of striking blocks 9 are inclined from top to bottom and outward. During use, the striking blocks 9 move downward to push the cutting tongues 8 to move closer, thereby achieving clamping and limiting.

[0027] Further, see Figure 3 and Figure 4 It can be seen that there are two groups of cutting tongues 8, and the top ends of the two groups of cutting tongues 8 are inclined from top to bottom and outward. The cutting tongues 8 conflict with the inclination of the striking block 9. During use, the cutting tongues 8 are pulled to move by the rubber 7, thereby facilitating the pushing of the striking block 9 to move upward and reset.

[0028] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, first, the operator fixes the side arc punching and punching forming mold on the punch press, and the upper mold plate 1 moves downward under the pressure of the punch press movement, thereby causing the left and right striking blocks 9 to move downward, and the left and right cutting tongues 8 to move toward the middle, applying pressure to the square tube body 6, the cutting tongues perform arc cutting, and the punch performs punching, so that the square tube body 6 is formed to meet the product requirements. After the pressure of the punch press disappears, the striking block 9 moves upward due to the elastic force of the rubber 7, and the left and right cutting tongues 8 recover to the left and right. After the rubber material of the material removal rod 12 is restored, it is convenient to take out the processed square tube. The above is the entire working principle of the utility model.
