Description

Technical Field

[0001] The utility model relates to the field of C-shaped steel, and more specifically, to a punching mechanism for C-shaped steel production. Background Art

[0002] C-shaped steels are all automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of C-shaped steel according to the given C-shaped steel size.

[0003] In the process of C-shaped steel production, facing different application requirements, secondary punching processing is required on some C-shaped steels. However, it is found in the actual punching process that when punching on the two side walls of the C-shaped steel, the middle part is in a vacant state. Therefore, when receiving the punching force, the two sides of the C-shaped steel are prone to twist and deformation, thus affecting the subsequent assembly and use.

[0004] Therefore, we make improvements and propose a punching mechanism for C-shaped steel production. Content of the Utility Model

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0041] Therefore, the following detailed description of the embodiments of the present utility model is not intended to limit the scope of the present utility model claimed, but merely represents some embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0042] Such asFigures 1-5 As shown in the figure, this embodiment proposes a punching mechanism for C-shaped steel production, including a base 1 and a punching structure 2 fixed above the base 1. A support rod 11 is provided at the center of the upper surface of the base 1, and a support structure 3 is assembled on the support rod 11 for punching support of the C-shaped steel;

[0043] The middle part of the support rod 11 is also connected with an adjusting structure 4 for adjusting the support range of the support structure 3. Among them, the support structure 3 includes support plates 31 slidably sleeved at both ends of the support rod 11 and a spring 32 sleeved on the surface of the support rod 11. One end of the spring 32 is connected to the corresponding support plate 31 and the other end is connected to the middle part of the support rod 11. Under the support action of the spring 32, the two support plates 31 are in a close state;

[0044] A limit handle 33 is fixed at the end of the support rod 11, and the support plate 31 can slide along the height direction of the support rod 11. As Figure 1 shown, the support plate 31 can only slide along the height direction of the support rod 11 and cannot rotate relative to the support rod 11. Specifically, a strip-shaped groove (not shown in the figure) can be opened on the surface of the support rod 11, so that the support plate 31 can be slidably engaged with the support rod 11 in the length direction through the strip-shaped groove;

[0045] The support plate 31 extends outward with a support platform 34, and the support platform 34 is correspondingly arranged with a contact plate 43;

[0046] As Figure 1 and Figure 2 shown, in the actual punching process, since the upper and lower support plates 31 are respectively supported on the inner walls of the side wings of the C-shaped steel, when the punching structure presses down for punching operation, the contact force received by the side wing walls of the C-shaped steel will be transmitted to the support plates 31, thus avoiding the problem of distorting the C-shaped steel and affecting subsequent use;

[0047] A telescopic rod 110 is slidably arranged at the bottom of the support rod 11, the telescopic rod 110 is fixedly connected to the surface of the base 1, and a limit bolt 111 for limiting the telescopic rod 110 is threadedly penetrated through the surface of the support rod 11. A through groove 310 for punching is opened on the surface of the support plate 31;

[0048] By removing the limit bolt 111 and adjusting the height of the support rod 11 on the surface of the telescopic rod 110, the height of the gap between the lower support plate 31 and the base 1 can be adjusted, so that when facing the side wing thicknesses of different models of C-shaped steel, it can be adjusted and used adaptively;

[0049] The adjustment structure 4 includes a connecting member 41 fixed to the middle of the support rod 11 and a telescopic transmission rod 42 connected to the outside of the connecting member 41. The telescopic transmission rod 42 can be telescoped in the length direction without axial rotation, wherein a resisting plate 43 is fixed to the surface of the telescopic transmission rod 42;

[0050] The adjustment structure 4 also includes a limit plate 44 fixed on the base 1, and the limit plate 44 is sleeved on the surface of the telescopic transmission rod 42 and is coaxially arranged therewith;

[0051] A rotary handle 45 is fixed at one end of the telescopic transmission rod 42, and a limit post 46 is fixed at one end of the rotary handle 45;

[0052] The surface of the limiting plate 44 is provided with a limiting groove 47 adapted to the limiting column 46;

[0053] Specifically, when the support structure 3 needs to be adaptively adjusted according to the C-shaped steel of different signals, the contact plate 43 on the telescopic transmission rod 42 is rotated to rotate synchronously. The contact plate 43 contacts the support platform 34 on the outer support plate 31 during the rotation process. The support platform 34 under the action of the contact force will overcome the action force of the spring 32 and expand outward, thereby increasing the support range of the support structure 3.

[0054] At the same time, the telescopic transmission rod 42 is rotated in the opposite direction to reduce the interference force between the contact plate 43 on it and the corresponding support platform 34. The two support plates 31 are moved closer to each other by the force of the spring 32 to reduce the support space. Finally, it is only necessary to make the two support plates 31 respectively fit on the side wing wall of the C-shaped steel, and then slide the limit handle 33 to make the limit column 46 on it plug into the corresponding limit plate 44 to form a positioning, and then the punching operation can be carried out;

[0055] The punching structure 2 includes a frame 21 fixed at the edge of the base 1 and a hydraulic drive rod 22 connected to the frame 21, and the output end of the hydraulic drive rod 22 is connected to a punching head 23;

[0056] After the C-shaped steel is supported and fixed, the hydraulic driving rod 22 is started to drive the punching head 23 to move, and the downwardly moved punching head 23 will contact the C-shaped steel to perform a punching operation.

[0057] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
