Description

Technical Field

[0001] The utility model relates to the technical field of positioning for punching, in particular to a positioning tool for angle steel punching. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. Angle steel can be divided into equal-leg angle steel and unequal-leg angle steel. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, warehouse shelves, etc. Angle steel needs to be punched with a punching machine.

[0003] Existing punching positioning technology often uses an angle steel punching positioning device for a stamping machine disclosed in announcement number CN211386509U, which places the angle steel on the stamping lower die, controls the stamping upper die to move downward, and after the first punching hole is made in the angle steel, pulls the limit rod in the direction away from the ball head column, the limit block returns to the initial position, and positions the positioning block. The pulling column is pulled in the direction away from the positioning block, the positioning spring rebounds, and the positioning block positions the angle steel. However, this technology places the angle steel directly on the upper film, and during the stamping process, the angle steel will be subjected to the impact caused by the lower film. Due to the lack of supporting stress measures, position deviation is very likely to occur, causing the next punching component to deviate from the preset position. Utility Model Content

[0004] The utility model aims to solve the problem of instability of fixed angle steel in the prior art and proposes a positioning tool for punching angle steel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning tool for punching angle steel comprises a main body with two ends normally open, a telescopic cylinder fixedly installed on one side of the main body, a traction mechanism driven by the telescopic cylinder slidably installed in the main body, a rectangular through groove is opened on the main body, and the rectangular through groove is a stepped structure, and a fixing mechanism for fixing and clamping the angle steel is slidably installed in the rectangular through groove.

[0007] Preferably, the traction mechanism includes a first sliding plate matched with the output end of the telescopic cylinder, an axle seat is welded on the first sliding plate, a buckle is rotatably installed in the axle seat, and a connecting plate is welded on one side of the buckle, and a strong spring connected to the first sliding plate is welded on the connecting plate.

[0008] Preferably, the buckle is a crescent-shaped structure composed of an arc plate and a straight plate.

[0009] Preferably, the fixing mechanism includes a second sliding plate slidably installed in a rectangular through groove, a resistance block is matchedly installed on one side of the second sliding plate, and a threaded hole is provided on the resistance block, a clamping block is slidably installed on the second sliding plate, a base is welded on the second sliding plate, and a rotating shaft is rotatably installed on the base, a resistance disk is fixedly installed on the rotating shaft, a handle is welded on the top end of the rotating shaft, a limit bolt for locking the position of the resistance disk is threadedly connected to the handle, a connecting block is welded on the bottom end of the second sliding plate, and a serration for measuring the punching spacing is provided on the connecting block.

[0010] Preferably, the abutment disc is eccentrically welded to the rotating shaft, and the saw teeth are abuttingly connected with the buckle.

[0011] Preferably, grooves for punching holes are provided at the upper ends of the abutment block and the clamping block.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model utilizes the elastic force of a strong spring, and the buckle will always fit with the saw teeth. After the telescopic cylinder pushes the first sliding plate, the telescopic cylinder is controlled to reset the first sliding plate. At this time, the buckle will form a conflict with the saw teeth, causing the second sliding plate to be pulled and slide in the rectangular through groove. The punching distance can be freely controlled according to the spacing between the saw teeth.

[0014] 2. After the resistance disk is rotated, the utility model controls the clamping block and the resistance block to clamp the angle steel. After reaching the rotation limit, the bolt is screwed to fix the position of the resistance disk, thereby ensuring that the angle steel will not be offset during the stamping process.

DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1-Figure 3 A positioning tool for punching angle steel comprises a main body 1 with two ends normally open, a telescopic cylinder 2 is fixedly installed on one side of the main body 1, a traction mechanism driven by the telescopic cylinder 2 is slidably installed in the main body 1, a rectangular through groove 3 is opened on the main body 1, and the rectangular through groove 3 is a stepped structure, and a fixing mechanism for fixing and clamping the angle steel is slidably installed in the rectangular through groove 3.

[0021] The traction mechanism includes a first sliding plate 4 which is matched and connected to the output end of the telescopic cylinder 2. An axle seat 5 is welded on the first sliding plate 4. A buckle 6 is rotatably installed in the axle seat 5. The buckle 6 is a crescent-shaped structure composed of an arc plate and a straight plate, and a connecting plate 7 is welded on one side of the buckle 6. A strong spring 19 connected to the first sliding plate 4 is welded on the connecting plate 7. When the sliding plate is controlled to slide forward, the buckle 6 will deflect counterclockwise. At this time, the strong spring 19 is squeezed by external force and undergoes elastic deformation. When the buckle 6 moves to the gap between the saw teeth 18, the external force disappears, the strong spring 19 returns to its state, and the buckle 6 will also be reset and conflict with the saw teeth 18.

[0022] The fixing mechanism includes a second sliding plate 8 slidably installed in the rectangular through groove 3, a resistance block 9 is matched and installed on one side of the second sliding plate 8, and a threaded hole 10 is provided on the resistance block 9. In order to adapt to angle steels of various thicknesses, the resistance block 9 is installed on the second sliding plate 8 by screws. When the maximum clamping spacing needs to be changed, the resistance block 9 can be replaced by loosening and tightening the screws. A clamping block 11 is slidably installed on the second sliding plate 8, and grooves for punching are provided on the upper ends of the resistance block 9 and the clamping block 11. A base 12 is welded on the second sliding plate 8, and a rotating shaft 13 is rotatably installed on the base 12. A resistance disk 14 is fixedly installed on the rotating shaft 13, and the resistance disk 14 is eccentrically welded to the rotating shaft On the shaft 13, a handle 15 is welded to the top of the rotating shaft 13, and a limit bolt 16 for locking the position of the abutment disk 14 is threadedly connected to the handle 15. When the limit bolt 16 is screwed, the bottom end of the limit bolt 16 will contact the second sliding plate 8, and the friction coefficient between the two is large, and there is pressure applied to the second sliding plate 8 by the limit bolt 16, so that the position of the handle 15 can be fixed, and a connecting block 17 is welded to the bottom end of the second sliding plate 8, and a sawtooth 18 for measuring the punching spacing is provided on the connecting block 17. The spacing of the sawtooth 18 in each section is a fixed value, and the spacing of the punching positions is determined by controlling the number of sections of the buckle 6 contacting the sawtooth 18, and the sawtooth 18 is in abutment with the buckle 6.

[0023] It should be noted that the specific model and specifications of the telescopic cylinder 2 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0024] The functional principle of the utility model can be explained through the following operation modes:

[0025] Place the angle steel between the abutment block 9 and the clamping block 11, rotate the handle 15 clockwise, the abutment plate 14 abuts against the clamping block 11, at this time, the clamping block 11 slides forward and forms an extrusion with the abutment block 9, when the handle 15 is rotated to the limit, tighten the limit bolt 16 to fix the position of the handle 15, and the angle steel can be clamped and fixed;

[0026] Open the telescopic cylinder 2, control the first sliding plate 4 to slide forward, pull the buckle 6 to the specified position at the lower end of the connecting block 17, and then control the first sliding plate 4 to move backward, so as to pull the second sliding plate 8 to slide in the rectangular through groove 3, and control the spacing of the punching holes according to the distance between each sawtooth 18;

[0027] When the second sliding plate 8 needs to be controlled to be reset, the connecting plate 7 only needs to be pressed down, so that the second sliding plate 8 can be controlled to slide freely in the rectangular through groove 3 .

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
