DETAILED DESCRIPTION
[0028] The technical scheme in the present application embodiment is to solve the problems in the above background art, and the general idea is as follows:
[0029] Embodiment 1:
[0030] This embodiment introduces the specific structure of an adjustable punching device. Referring to Figs. Figure 1 , Figure 2 , Figure 4 and Figure 5 , it includes a carrier frame 3, a base structure 7 movably connected to the top of the carrier frame 3, and a punching device body 6 assembled to the top of the base structure 7. The inside of the carrier frame 3 is placed with a guardrail net 1, and a plurality of plates 5 are welded at the two edges of the guardrail net 1. A strip-shaped groove A2 is processed on the top of the carrier frame 3, and a strip-shaped groove B4 is processed on the side of the carrier frame 3.
[0031] As shown in Figs. Figure 2 , Figure 4 and Figure 5 , the base structure 7 includes a support leg 701, and four wing plates 702 are integrally formed on the surface of the support leg 701. The bottom of the support leg 701 on both sides is provided with a buckle plate 704.
[0032] Among them, the cross section of the support leg 701 is U-shaped, and the four wing plates 702 are respectively located on the front and back of the support leg 701, and are arranged on the left and right. When the wing plate 702 and the buckle plate 704 are respectively located on the top and the bottom of the carrier frame 3, and the bottom of the support leg 701 can slide in the inside of the strip-shaped groove A2, the wing plate 702 and the buckle plate 704 can be used for limiting, and the support punching device body 6 can be moved from one side to the other side of the punching device body 6.
[0033] At the same time, when the plurality of plates 5 at the edge of the guardrail net 1 are passed through the strip-shaped groove B4 from the inside of the carrier frame 3 to the outside of the carrier frame 3, the base structure 7 and the strip-shaped groove A2 can be moved from one corner to another corner on the top of the carrier frame 3, and the circular holes can be processed in the inside of the plurality of plates 5 from the top to the bottom of the carrier frame 3 in succession, so as to meet the assembly requirements of the subsequent guardrail net 1.
[0034] Secondly, in order to reduce the resistance of the support leg 701 moving in the strip-shaped groove A2, as shown in Fig. Figure 4 , the bottom surface of the wing plate 702 and the top surface of the buckle plate 704 on both ends are provided with a roller 703. By making the rolling direction of the roller 703 parallel to the long side of the strip-shaped groove A2, the support of the roller 703 can be used to avoid the direct contact between the wing plate 702, the buckle plate 704 and the surface of the carrier frame 3, and to ensure the smooth sliding of the support leg 701 in the inside of the strip-shaped groove A2.
[0035] Further, in order to ensure that the roller 703 is supported between the wing plate 702 and the carrier frame 3, and the buckle plate 704 and the carrier frame 3, and to avoid that the roller 703 is pressed too much to hinder its rotation, as shown in Fig. Figure 5 , the bottom surface of the wing plate 702 and the top surface of the buckle plate 704 on both ends are provided with a roller 703. By making the rolling direction of the roller 703 parallel to the long side of the strip-shaped groove A2, the support of the roller 703 can be used to avoid the direct contact between the wing plate 702, the buckle plate 704 and the surface of the carrier frame 3, and to ensure the smooth sliding of the support leg 701 in the inside of the strip-shaped groove A2.As shown, the bottom of the support leg 701 on both sides is formed with a positioning column 705 by a mold, and a cylindrical groove 9 is formed synchronously, the outer part of the positioning column 705 is connected with a spring 707 in a sleeving type, the bottom of the buckle plate 704 is provided with a limiting disc 706, by making the spring 707 inside the cylindrical groove 9, the bolt is screwed with one end of the positioning column 705 through the inside of the limiting disc 706 and the buckle plate 704, when the limiting disc 706 and the positioning column 705 are fixed, the buckle plate 704 can be movably connected to the outside of one end of the positioning column 705, which can provide a small automatic adjustment (based on the elasticity of the spring) for the distance between the roller 703 and the surface of the bearing frame 3.
[0036] At the same time, when one end of the spring 707 is supported on the inner wall of one end of the cylindrical groove 9 and the surface of the buckle plate 704, it can prevent the bolt connected to the inside of one end of the positioning column 705 from loosening.
[0037] The above design makes the support leg 701 installed from the top to the bottom inside the strip-shaped groove A2, the wing plate 702 on the surface of the support leg 701 is located at the top of the bearing frame 3, and the buckle plate 704 is assembled with the positioning column 705 through the limiting disc 706, which can be moved outside one end of the positioning column 705 (and supported by the spring 707 between the buckle plate 704 and the support leg 701), and the roller 703 on the surface of the buckle plate 704 and the wing plate 702 can be supported on the surface of the bearing frame 3, which can make the support leg 701 smoothly move inside the strip-shaped groove A2, drive the punching device main body 6 to move from one side to the other side on the top of the bearing frame 3, and facilitate the punching device main body 6 to successively process circular holes in the inside of the multiple plates 5 when the multiple plates 5 at the edge of the guardrail net 1 are passed from the inside of the bearing frame 3 to the outside of the bearing frame 3 through the strip-shaped groove B4, so as to meet the subsequent assembly requirements of the guardrail net 1. In this state, because the direction of the drill bit processing the circular hole is always the same and is not easy to change, it is easy to get multiple circular holes with parallel axes.

[0040] Wherein, by making the threaded rod 807 threadedly connected inside the bearing frame 3, and the guide rod A 802 and the guide rod B 803 are both slidingly connected to the inside of the bearing frame 3, the path of the pressing plate 801 up and down movement can be controlled by the guide rod A 802 and the guide rod B 803 when adjusting the threaded condition of the threaded rod 807 and the bearing frame 3.
[0041] Secondly, in order to facilitate the assembly of the guide rod B 803 and the guide rod A 802, the guide rod B 803 and the guide rod A 802 are not too long to be difficult to install inside the bearing frame 3, as shown in Figure 3 The end surface of the guide rod B 803 is machined with a cutout symmetrical to the axis, and the end of the guide rod A 802 is machined with a screw rod. By threadedly connecting the end of the guide rod B 803 to the outside of the guide rod A 802 screw rod, the detachability of the guide rod A 802 and the guide rod B 803 is ensured, which is beneficial to the actual installation work;
[0042] Further, by setting the cross section of the limiting piece A 805 as T-shaped, the limiting piece A 805 can be installed inside the limiting piece B 806 from one side, so as to push and pull the pressing plate 801 by the threaded rod 807.
[0043] At the same time, by assembling the threaded rod 807 to the top of the limiting piece A 805, the threaded rod 807 can be interference fitted to the top of the limiting piece A 805, so as to complete the connection of the threaded rod 807 and the limiting piece A 805, and finally realize the fixation of the guardrail net 1 inside the bearing frame 3, so that when the plurality of plates 5 are extended from the inside of the strip-shaped groove B 4, the top of the guardrail net 1 is pressed by the clamping structure 8, and the guardrail net 1 is fixed inside the bearing frame 3.
[0044] The above design inserts the guardrail net 1 into the inside of the bearing frame 3, so that the plurality of plates 5 are extended from the inside of the strip-shaped groove B 4, the threaded connection of the threaded rod 807 and the bearing frame 3 is adjusted, the threaded rod 807 pushes the pressing plate 801 to move towards the bottom (the pressing plate 801 is guided by the guide rod A 802 and the guide rod B 803 at both ends), and the rubber strip 804 at the bottom of the pressing plate 801 is pressed at the frame of the guardrail net 1, so as to facilitate the fixation of the guardrail net 1 inside the bearing frame 3, and the punching device body 6 can be stably processed in the plurality of plates 5.
[0045] Finally, it should be noted that: obviously, the above examples are only examples for clearly illustrating the present application, and are not limited to the embodiments.
