DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0029] As Figures 1-5 shown, the steel structure punching device in the embodiment is mainly used for punching angle steel 1, and further explanation is that it is mainly used for punching equilateral angle steel 1, and of course, it can also be used for punching unequal angle steel 1. The steel structure punching device comprises a platform 2, a rack 3, a position adjusting assembly 5 and two sets of punching parts 4. The platform 2 is used for placing the angle steel 1, the rack 3 is arranged on the platform 2, the two sets of punching parts 4 are symmetrically arranged on the rack 3, and the position adjusting assembly 5 is arranged at the center of the rack 3. The position adjusting assembly 5 is used for synchronously adjusting the positions of the two sets of punching parts 4, so as to punch the angle steel 1 of different sizes.

[0030] In order to conveniently place the angle steel 1 at the symmetric center of the two sets of punching parts 4, it needs to be explained that the waste outlet hole 21 is formed in the platform 2, and two sets of workpiece tables 22 are fixed on the platform 2. The two sets of workpiece tables 22 are symmetrically distributed on the two sides of the waste outlet hole 21, and the angle steel 1 is placed on the workpiece table 22. At this time, the region between the two sets of workpiece tables 22 is a machining region used for punching by the punching parts 4. In this way, the waste produced by punching can be discharged through the waste outlet hole 21.

[0031] The following will describe the frame 3, the punching component 4, and the position adjustment assembly 5.

[0032] Firstly, as Figure 1 As shown, the frame 3 in this embodiment includes a top plate 31 located above the platform 2, which can meet the space requirements of the workpiece table 22 and the angle steel 1. Two sets of inclined panels 32 are symmetrically distributed on the outside of the top plate 31. The inclined panels 32 are inclined towards the platform 2, and the angle between the inclined panels 32 and the top plate 31 is 135 degrees. In this design, the extension lines of the two sets of inclined panels 32 are perpendicular to each other. A side plate 33 is fixed on the side of the inclined panel 32 away from the top plate 31. The side plate 33 is vertically arranged and is fixed to the platform 2, for example, by bolts. The inclined panel 32 is provided with sliding holes 34.

[0033] It should be noted that the workpiece table 22 has two sets of inclined surfaces that are symmetrically distributed. The inclined surfaces are parallel to the adjacent inclined panel 32. This design allows the punching direction of the punching component 4 to be perpendicular to the corresponding side of the angle steel 1, ensuring that the punching can be completed smoothly.

[0034] And such Figure 1 and 4 As shown, in this embodiment, there are two sets of punched components 4, which are slidably connected to the corresponding sliding holes 34 and inclined panels 32 respectively.

[0035] Further explanation: The punching component 4 includes a slide base 41, on which a hydraulic cylinder 42 is provided. The telescopic end of the hydraulic cylinder 42 passes through the slide base 41 and connects to and installs a punching head 43. At this time, the punching head 43 is perpendicular to the corresponding side of the angle steel 1. The slide base 41 consists of a slider and two sets of plates. The slider is fixed between the two sets of plates and is slidably connected in the sliding hole 34. The plates are distributed on both sides of the inclined plate 32. This design ensures that the punching component 4 can only move linearly along the sliding hole 34.

[0036] like Figure 1 and 2 As shown, the position adjustment component 5 in this embodiment includes a three-way housing 51 and a lifting component connected to the three-way housing 51. The lifting end of the lifting component is provided with a connecting rope 52 connected to the two sets of punching components 4.

[0037] As a preferred embodiment of the lifting component in this application, such as Figures 1-3As shown, the lifting component includes a motor 53 fixed on the top of the three-way shell 51 by bolts, a lead screw 54 is arranged at the output end of the motor 53, a slide rod 55 is arranged in the three-way shell 51 and symmetrically distributed on both sides of the lead screw 54, a nut seat 56 is arranged on the outside of the lead screw 54, the nut seat 56 is in sliding connection with the two groups of slide rods 55, and one end of the connecting rope 52 is fixed to the bottom of the nut seat 56. At this time, the motor 53, the lead screw 54, the slide rod 55 and the nut seat 56 can constitute a lead screw nut structure.

[0038] Therefore, when the motor 53 drives the lead screw 54 to work, the nut seat 56 can move up and down, and in the up and down movement of the nut seat 56, the punching component 4 moves linearly along the slide hole 34, so as to change the punching position to adapt to the angle steel 1 of different sizes.

[0039] It can be understood that, as Figure 5 As shown in another embodiment, the lifting component includes a telescopic piece 57 fixed on the top of the three-way shell 51 by bolts, a connecting block 58 is arranged at the telescopic end of the telescopic piece 57, and one end of the connecting rope 52 is fixed to the bottom of the connecting block 58. The telescopic piece 57 is one of a pneumatic cylinder or an electric push rod.

[0040] When designed in this way, the telescopic adjustment of the telescopic piece 57 completes the up and down adjustment of the connecting block 58. Similarly, in the up and down movement of the connecting block 58, the punching component 4 moves linearly along the slide hole 34, so as to change the punching position to adapt to the angle steel 1 of different sizes.

[0041] In addition, in order to avoid friction between the connecting rope 52 and the three-way shell 51, two groups of guide groups are arranged in the three-way shell 51, each group of guide groups includes a plurality of fixed pulleys 59, and the fixed pulleys 59 are in rotating connection with the three-way shell 51. In this way, the rolling relationship between the fixed pulleys 59 and the connecting rope 52 can reduce the damage of the connecting rope 52.

[0042] Furthermore, the bottom of the platform 2 is fixed with support feet arranged on the ground, so that a height difference can be formed between the platform 2 and the ground. At this time, the bottom of the platform 2 is provided with a collection box 23, and an open mouth is arranged on the collection box 23 and located below the waste outlet hole 21. In this way, the waste generated by punching can be collected into the collection box 23.

[0043] The operation is as follows:

[0044] When punching the angle steel 1 with equal sides, the position of the two groups of punching components 4 is directly adjusted by using the position adjusting assembly 5, and then the two groups of hydraulic cylinders 42 are started in sequence, so that the punching head 43 can complete the punching work on both sides of the angle steel 1.

[0045] When punching the unequal angle steel 1, the position adjusting assembly 5 is used to directly adjust the position of the two sets of punching components 4 until the corresponding punching component 4 reaches the punching position of one side of the angle steel 1, and then the punching is performed, and then the position adjusting assembly 5 is restarted to adjust the position of the two sets of punching components 4 until the other set of punching component 4 reaches the punching position of the other side of the angle steel 1, and then the punching is performed.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and all of them should be covered within the protection scope of the present application.
