Description

Technical Field

[0001] This utility model relates to the field of angle steel bending technology, and in particular to a bending auxiliary material rack. Background Technology

[0002] In the production of angle steel, it is often necessary to bend it into a certain arc to meet different application requirements. Auxiliary bending templates are often used to assist in bending. Existing bending templates can only bend angle steel of one arc type at a time; different templates must be changed to produce angle steel of different arcs. However, existing bending templates are fixed to the material rack with bolts, making disassembly and replacement cumbersome. Therefore, there is an urgent need to develop a bending auxiliary material rack that allows for quick switching and facilitates the production of angle steel with different arcs, overcoming the shortcomings of current applications and meeting current needs. Utility Model Content

[0003] The purpose of this utility model is to provide a bending auxiliary material rack to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bending auxiliary material rack includes a worktable, a limiting mechanism, an extrusion mechanism, a quick-change bending mechanism, and a rotation switching mechanism. The quick-change bending mechanism is rotatably connected to the worktable. The rotation switching mechanism is installed on the lower side of the worktable and drives the quick-change bending mechanism to rotate. The extrusion mechanism is installed on the lower side of the worktable and limits the position of the quick-change bending mechanism. The quick-change bending mechanism includes: a support shaft, an inner die head, an outer die head, a vertical plate, a guide rod, and a spring. The support shaft is rotatably connected to the worktable. Four inner die heads are evenly distributed and fixed on the outside of the support shaft. Each inner die head has an opposite outer die head on its outer side. The upper part is provided with a first arc surface, and the curvature of the four first arc surfaces is different. Each outer mold head is provided with a second arc surface, and the curvature of the four second arc surfaces is different. The curvature of the first arc surface and the second arc surface facing each other is the same. Each inner mold head is fixed with a vertical plate. Each outer mold head is fixed with two guide rods. The guide rods pass through the vertical plate and slide in contact with it. A spring is installed on the outside of each guide rod. One end of the spring is fixed to the guide rod and the other end is fixed to the vertical plate. Each inner mold head is provided with two positioning holes for the limiting mechanism to pass through. The extrusion mechanism is installed on the worktable and is used to push the outer mold head to move.

[0006] Preferably, a 5 mm gap is left between the bottom of the inner mold head and the worktable.

[0007] Preferably, the limiting mechanism includes a first hydraulic cylinder, a lifting plate, and pins. The first hydraulic cylinder is fixed to the lower side of the worktable, and the telescopic end of the first hydraulic cylinder is fixed to the lifting plate. Two pins are fixed on the lifting plate, and the pins are used to penetrate the worktable and insert into the positioning hole.

[0008] Preferably, the extrusion mechanism includes a second hydraulic cylinder and a push plate. Two second hydraulic cylinders are fixed on the worktable, and the telescopic ends of the second hydraulic cylinders are fixed to the push plate.

[0009] Preferably, the rotary switching mechanism includes a servo motor, a first gear, and a second gear. The servo motor is fixed to the lower side of the worktable, and the first gear is fixed on the output shaft of the servo motor. A second gear is provided on one side of the first gear to mesh with it, and the transmission ratio of the first gear and the second gear is 1:1.

[0010] The beneficial effects of this utility model are as follows: When using this bending auxiliary material rack, the inner and outer die heads with the required curvature are first selected. During switching, the first hydraulic cylinder drives the lifting plate and pin to move downwards, causing the pin to move out of the positioning hole. Then, the servo motor drives the first and second gears to rotate, which in turn drives the support shaft to rotate. The support shaft then drives the four inner die heads to rotate and switch, allowing the inner and outer die heads with the required curvature to rotate to the extrusion mechanism. Next, the first hydraulic cylinder drives the lifting plate and pin to move upwards, causing the pin to insert into the positioning hole and fix the inner die head. Then, the angle steel is placed between the inner and outer die heads. The second hydraulic cylinder then drives the push plate to move, pushing the outer die head closer to the inner die head. The outer die head then extrudes the angle steel, bending it into the curvature of the first arc surface. By setting four different first arc surfaces, angle steel with different curvatures can be processed. In summary, this utility model offers quick and convenient switching, facilitating the production of angle steel with different curvatures. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-6In this embodiment of the utility model, a bending auxiliary material rack includes a worktable 1, a limiting mechanism 2, an extrusion mechanism 3, a quick-change bending mechanism 4, and a rotation switching mechanism 5.

The rotation switching mechanism 5 is installed on the lower side of the worktable 1 and is used to drive the quick-change bending mechanism 4 to rotate. The extrusion mechanism 3 is installed on the lower side of the worktable 1 and is used to limit the position of the quick-change bending mechanism 4. The quick-change bending mechanism 4 includes: a support shaft 401, an inner die head 402, an outer die head 403, a vertical plate 404, a guide rod 405, and a spring 406. The support shaft 401 is rotatably connected to the worktable 1. Four inner die heads 402 are evenly distributed and fixed on the outside of the support shaft 401. Each inner die head 402 has an opposite outer die head 403 on its outer side. Each inner die head 402 is provided with a first arc surface 40. 21. The curvature of the four first arc surfaces 4021 is different. Each outer die head 403 is provided with a second arc surface 4031. The curvature of the four second arc surfaces 4031 is different. The curvature of the first arc surfaces 4021 and the second arc surfaces 4031 facing each other is the same, so as to produce angle steel with different curvatures. Each inner die head 402 is fixed with a vertical plate 404. Each outer die head 403 is fixed with two guide rods 405. The guide rods 405 pass through the vertical plate 404 and slide in contact with it. Each guide rod 405 is equipped with a spring 406 on its outer side. One end of the spring 406 is fixed to the guide rod 405 and the other end is fixed to the vertical plate 404. Each inner die head 402 is provided with two positioning holes 4022 for the limit mechanism 2 to pass through. The extrusion mechanism 3 is installed on the worktable 1 and is used to push the outer die head 403 to move.

[0022] A 5 mm gap is left between the bottom of the inner mold head 402 and the worktable 1 to allow the angle steel to pass through.

[0023] The limiting mechanism 2 includes: a first hydraulic cylinder 201, a lifting plate 202, and pins 203. The first hydraulic cylinder 201 is fixed to the lower side of the worktable 1. The telescopic end of the first hydraulic cylinder 201 is fixed to the lifting plate 202. Two pins 203 are fixed on the lifting plate 202. The pins 203 are used to penetrate the worktable 1 and insert into the positioning hole 4022. When the pins 203 penetrate the worktable 1 and insert into the positioning hole 4022, the inner mold head 402 is fixed and cannot rotate.

[0024] The extrusion mechanism 3 includes a second hydraulic cylinder 301 and a push plate 302. Two second hydraulic cylinders 301 are fixed on the worktable 1. The telescopic ends of the second hydraulic cylinders 301 are fixed to the push plate 302. In use, the push plate 302 is moved by the second hydraulic cylinders 301, and the push plate 302 pushes the outer die head 403.

[0025] The rotary switching mechanism 5 includes a servo motor 501, a first gear 502, and a second gear 503. The servo motor 501 is fixed to the lower side of the workbench 1. The first gear 502 is fixed on the output shaft of the servo motor 501. A second gear 503 is provided on one side of the first gear 502 to mesh with it. The transmission ratio of the first gear 502 and the second gear 503 is 1:1. The output shaft of the servo motor 501 rotates 90° each time to ensure accurate switching. In use, the servo motor 501 drives the first gear 502 and the second gear 503 to rotate, and the second gear 503 drives the support shaft 401 to rotate.

[0026] Working principle: When using this bending auxiliary material rack, the inner die head 402 and outer die head 403 of the required curvature are first selected. During switching, the first hydraulic cylinder 201 drives the lifting plate 202 and the pin 203 to move downwards, causing the pin 203 to move out of the positioning hole 4022. Then, the servo motor 501 drives the first gear 502 and the second gear 503 to rotate. The second gear 503 drives the support shaft 401 to rotate, which in turn drives the four inner die heads 402 to rotate and switch, allowing the inner die head 402 and outer die head 403 of the required curvature to rotate to the extrusion mechanism 3. Then, the first hydraulic cylinder 201 drives the lifting plate 202 and the pin 203 to move upward, so that the pin 203 is inserted into the positioning hole 4022 to fix the inner mold head 402. Then, the angle steel is placed between the inner mold head 402 and the outer mold head 403. Then, the second hydraulic cylinder 301 drives the push plate 302 to move, and the push plate 302 pushes the outer mold head 403 closer to the inner mold head 402. The outer mold head 403 squeezes the angle steel, so that the angle steel is bent into the arc of the first arc surface 4021. By setting four different first arc surfaces 4021, angle steels with different arcs can be processed.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
