Description

Technical Field

[0001] This utility model relates to the technical field of hanger material processing, and in particular to a simple and portable hanger angle iron cutting device. Background Technology

[0002] Angle iron is a commonly used material in construction, which can be used to form various load-bearing components as needed. Its physical properties make it a frequent main material for hangers. Angle iron has standardized specifications, with a length generally between 6m and 12m. Therefore, it needs to be cut and welded before use in welded hangers.

[0003] The current method of cutting angle iron involves directly cutting the angle iron using an angle grinder or cutting saw. The cut angle iron end face is prone to being uneven, and it needs to be ground and repaired before use, which is inconvenient. In addition, the angle iron cutting process is also relatively slow, affecting the construction progress.

[0004] Therefore, a device is needed to easily cut angle iron. Utility Model Content

[0005] The purpose of this invention is to solve the above problems and provide a simple and portable angle iron cutting device for hangers.

[0006] The technical solution of this utility model is: a simple and portable angle iron cutting device, including a frame, a hydraulic cutting mechanism and an angle iron fixing frame; the frame includes mounting plates arranged at the front and rear, and a fixing plate is arranged between the two mounting frames; The hydraulic cutting mechanism includes a hydraulic cylinder, a piston rod, and a cutting head; the cutting head is plate-shaped, with its top fixed to the bottom end of the piston rod; the hydraulic cylinder is fixed between the tops of two mounting plates, and the piston rod extends vertically from between the two mounting plates; the cutting head is in contact with the fixed plate. The fixing plate has a V-shaped groove A in the middle, which matches the angle iron; the angle iron fixing bracket connects to the fixing plate and cooperates with the V-shaped groove A. The angle iron is fixed by the angle iron fixing bracket, and then the end of the angle iron is hydraulically cut by a hydraulic cutting mechanism. The structure is simple, it can accurately cut the end of the angle iron, and the cut end surface is flat, saving process steps.

[0007] Preferably, the angle iron fixing frame includes a lead screw and a positioning seat; the lead screw is vertically arranged and rotates with the machine frame; the positioning seat is located below the lead screw and is fixedly mounted on a fixed plate; a V-shaped groove B is provided in the middle of the positioning seat, and V-shaped groove A corresponds to V-shaped groove B. The angle iron is placed in the V-shaped groove, and the bottom of the lead screw blocks the angle iron to prevent it from tilting up during the cutting process and affecting the cutting effect.

[0008] Furthermore, the mounting base and the fixing plate are fixed together by bolts; a positioning sleeve is provided between the positioning base and the fixing plate. The positioning base can be fixed in position by bolts and positioning sleeve; in addition, the position of the positioning base can be adjusted by adjusting the length of the positioning sleeve as needed.

[0009] Preferably, vertical grooves are provided on both sides of the frame, and the cutting head slides within the two grooves. This allows the cutting head to move up and down along the grooves, reducing horizontal swaying during the cutting head's movement and improving the cutting accuracy of the angle iron.

[0010] Preferably, the cutting head is M-shaped overall, with a V-shaped cutting blade in the middle. The V-shaped cutting blade at the bottom of the cutting head can match the shape of the angle iron, so that it can cut all parts of the angle iron at the same time during cutting, thereby avoiding bending and deformation of the angle iron during the cutting process.

[0011] Preferably, the frame is mounted on a pedestal. The pedestal elevates the hydraulic cutting mechanism, making it easier to use.

[0012] Preferably, the device further includes a support frame, which is disposed on the front of the frame; the height of the support frame matches the height of the V-shaped slot A on the fixed plate. Placing the angle iron on the support frame ensures that the height of the angle iron corresponds to the height of the hydraulic cutting mechanism, preventing the angle iron from tilting and causing the end of the angle iron to form a bevel after cutting, thus affecting the normal use of the angle iron.

[0013] Furthermore, a V-shaped slide is horizontally installed at the top of the support frame, which matches the angle iron. The angle iron can slide within the slide, allowing the angle iron cutting process to be continuous and more convenient.

[0014] The beneficial effects of this utility model are as follows: The simple and portable angle iron cutting device of this utility model has the following advantages: 1. This utility model uses an angle iron fixing bracket to fix the angle iron, and then uses a hydraulic cutting mechanism to hydraulically cut the end of the angle iron. The structure is simple, and it can accurately cut the end of the angle iron. The cut end surface is flat, saving process steps.

[0015] 2. The cutting head of this utility model is set in the slide groove on both sides of the machine frame, which enables the cutting head to move up and down along the slide groove, providing a sliding guide, reducing the horizontal swaying that occurs when the cutting head moves up and down, and improving the cutting accuracy of angle iron.

[0018] Example 1: See Figure 1-8 A simple and portable angle iron cutting device for hanging racks includes a frame 1, a hydraulic cutting mechanism 2 and an angle iron fixing frame 3; the frame 1 includes mounting plates 11 arranged at the front and rear, and a fixing plate 12 is arranged between the two mounting frames; The hydraulic cutting mechanism 2 includes a hydraulic cylinder 21, a piston rod 22, and a cutting head 23; the cutting head 23 is plate-shaped, and its top is fixed to the bottom end of the piston rod 22; the hydraulic cylinder 21 is fixed between the tops of two mounting plates 11, and the piston rod 22 extends vertically from between the two mounting plates 11; the cutting head 23 is in contact with the fixed plate 12. A hydraulic connector is provided on the hydraulic cylinder 21.

[0019] A V-shaped groove A 121 is provided in the middle of the fixing plate 12, which matches the angle iron; the angle iron fixing bracket 3 is connected to the fixing plate 12, and the angle iron fixing bracket 3 cooperates with the V-shaped groove A 121. The angle iron is fixed by the angle iron fixing bracket 3, and then the end of the angle iron is hydraulically cut by the hydraulic cutting mechanism 2. The structure is simple, and it can accurately cut the end of the angle iron. The cut end surface is flat, saving process steps.

[0020] The angle iron fixing bracket 3 includes a lead screw 31 and a positioning seat 32. The lead screw 31 is vertically arranged and rotatably engages with the frame 1. The positioning seat 32 is located below the lead screw 31 and is fixedly mounted on the fixing plate 12. A V-shaped groove 321 is provided in the middle of the positioning seat 32, and the V-shaped groove 121 corresponds to the V-shaped groove 321. The angle iron is placed in the V-shaped groove, and the bottom of the lead screw 31 blocks the angle iron to prevent it from tilting up during the cutting process and affecting the cutting effect.

[0021] The mounting base and the fixing plate 12 are fixed together by bolts; a positioning sleeve 15 is provided between the positioning base 32 and the fixing plate 12. The positioning base 32 can be fixed in position by bolts and positioning sleeve 15; in addition, the position of the positioning base 32 can be adjusted by adjusting the length of positioning sleeve 15 as needed.

[0022] Vertical grooves 13 are provided on the left and right sides of the frame 1, and the cutting head 23 is slidably fitted in the two grooves 13. This allows the cutting head 23 to move up and down along the grooves 13, reducing the horizontal swaying that occurs when the cutting head 23 moves up and down, and improving the cutting accuracy of the angle iron.

[0023] The cutting head 23 is M-shaped overall, with a V-shaped cutting blade in the middle. The V-shaped cutting blade at the bottom of the cutting head 23 can match the shape of the angle iron, so that it can cut all parts of the angle iron at the same time during cutting, thereby avoiding bending and deformation of the angle iron during the cutting process.

[0024] The frame 1 is mounted on a base 14. The base 14 lifts the hydraulic cutting mechanism 2, making it easier to use.

[0025] The device also includes a support frame 4, which is located on the front of the frame 1. The height of the support frame 4 matches the height of the V-shaped slot A 121 on the fixing plate 12. The angle iron is placed on the support frame 4, which ensures that the height of the angle iron corresponds to the height of the hydraulic cutting mechanism 2, preventing the angle iron from tilting and causing the end of the angle iron to form a bevel after cutting, thus affecting the normal use of the angle iron.

[0026] The top of the support frame 4 is horizontally equipped with a slide rail 41, which is V-shaped and matches the angle iron. The angle iron can slide within the slide rail 41, making the angle iron cutting process continuous and more convenient.

[0027] The working process of this embodiment includes the following steps: ① Place the angle iron in the slide rail 41 at the top of the support frame 4, and slide it forward to the position to be cut; ② Adjust the height of the lead screw 31 so that the bottom of the lead screw 31 rests on the angle iron; ③ Start the hydraulic cylinder 21, and the cutting head 23 descends along the slide 13, with the middle part of the cutting head 23 abutting against the groove of the angle iron; ④ The cutting head 23 continues to descend, cutting the angle iron to the bare metal; ⑤ Raise the cutting head 23, turn the screw 31, and release the diagonal iron from its fixed position; Repeat steps ① to ⑤, cutting the angle iron multiple times as needed.

[0028] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the angle iron fixing bracket 3 does not use a lead screw 31, but a hydraulic piston rod 22. The bottom of the hydraulic piston rod 22 is provided with a right-angle plate, which cooperates with the angle iron. The use of the hydraulic piston rod 22 and the right-angle plate can fix the angle iron more firmly, and it does not require manual operation, making it safer and more convenient.
