Description

Technical Field

[0001] This utility model relates to the field of angle steel processing technology, specifically to an angle steel bending machine. Background Technology

[0002] Angle steel processing refers to the process of processing and treating angle steel to meet specific shape, size and application requirements. Angle steel is usually made of carbon steel or stainless steel. When processing angle steel, a bending machine is needed to bend the angle steel.

[0003] As disclosed in the patent announcement CN219541409U, an angle steel bending machine has a frame, and an angle steel clamping mechanism and an angle steel bending mechanism are provided on the worktable of the frame. The angle steel bending mechanism is located on one side of the angle steel clamping mechanism. A pressure seat driven by a first driving device is also slidably installed on the frame along the vertical direction, and the pressure seat is located above the angle steel clamping mechanism and the angle steel bending mechanism. After adopting the above technical solution, the beneficial effects of this utility model are: it can realize bidirectional bending processing of angle steel, and under the combined action of the positioning clamping of the angle steel clamping mechanism and the positioning pressing of the angle steel pressing assembly, the workpiece can be better pressed and fitted, preventing the workpiece from loosening, thus greatly improving the bending accuracy of the workpiece.

[0004] Although the aforementioned patent can achieve bidirectional bending of angle steel, before bending, the upper end of the angle steel needs to be clamped and fixed by a hydraulic cylinder. Since the hydraulic cylinder is located directly above the top of the machine frame, and the angle steel to be processed is too long, it cannot be placed vertically from the top of the machine frame, but needs to be placed horizontally from one side. This requires a large operating space and is laborious to operate. Utility Model Content

[0005] The purpose of this utility model is to provide an angle steel bending machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An angle steel bending machine, comprising

[0008] Bending machine body;

[0009] A worktable is provided on one side of the upper end of the bending machine body, and a positioning table is provided on the upper right side of the worktable.

[0010] A clamping mechanism is provided on the left side of the workbench near the positioning table, and a pressure plate is movably installed directly above the top of the positioning table. A linkage mechanism is provided between the pressure plate and the clamping mechanism.

[0011] A bending mechanism is provided on the outer side of the workbench, which is close to the clamping mechanism and the positioning platform, in the same direction.

[0012] Preferably, the clamping mechanism includes a fixed base, which is fixedly installed on the upper left side of the worktable. Several cylinders are arranged side by side on the side of the fixed base away from the positioning table, and the output shafts of the cylinders are fixedly mounted with clamping plates.

[0013] Preferably, the linkage mechanism includes a pressure rod, which is fixedly connected to the outer two ends of the pressure plate on the side away from the clamping plate. The two ends of the worktable near the pressure rod are provided with rod grooves, and the bottom end of the pressure rod passes through the rod groove and is fixedly connected to a second inclined block.

[0014] Preferably, the linkage mechanism further includes guide grooves, and guide grooves are provided on both sides of the bottom end of the worktable near the clamping plate. Guide bars that are slidably connected to the guide grooves are provided on both bottom ends of the clamping plate. An inclined block one that matches the inclined block two is provided on one side of the bottom end of the guide bar.

[0015] Preferably, the bottom end of the inclined block two is provided with a bottom groove, and a spring is provided inside the bottom groove. The other end of the spring is fixedly connected to the bending machine body.

[0016] Preferably, the bending mechanism includes a frame, which is disposed on the side of the workbench near the clamping plate. A second cylinder is fixedly installed on the back of the frame. A push block is fixedly connected to the output shaft of the second cylinder. A sliding groove is provided on the workbench near the lower part of the push block. The bottom center of the push block is slidably connected to the sliding groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This type of angle steel bending machine uses the bending machine body, worktable, positioning table, clamping plate and push block in cooperation. The angle steel is put in from directly above the positioning table and the inner side of the angle steel abuts against the outer side of the positioning table. Then, cylinder one is started, and cylinder one controls the clamping plate to push forward. After the clamping plate pushes forward, it clamps the outer wall of the angle steel. In this way, when loading, the angle steel can be put in from directly above the top of the bending machine body, and when unloading, it can be taken out from the top of the bending machine body. This makes loading and unloading more convenient and does not occupy too much operating space.

[0019] 2. This angle steel bending machine uses a positioning table, a pressure plate, a clamping plate, and two inclined blocks in cooperation. When the clamping plate is driven forward, it will drive the guide bar to slide inside the guide groove and control the inclined block to move synchronously. When the inclined block moves, it presses down on the inclined block. When the inclined block is pressed down, it simultaneously compresses the spring at the bottom end and drives the pressure plate to descend through the pressure rod, clamping the other side of the angle steel to the upper end of the positioning table. In this way, the pressure plate and clamping plate can be controlled by the cylinder to clamp and fix both sides of the angle steel at the same time, thereby achieving the purpose of energy saving.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution:

[0027] An angle steel bending machine includes a bending machine body 1; a workbench 2 is provided on one side of the upper end of the bending machine body 1, a positioning table 3 is provided on the upper right side of the workbench 2, a clamping mechanism is provided on the left side of the workbench 2 near the positioning table 3, the clamping mechanism includes a fixed seat 5, the fixed seat 5 is fixedly installed on the upper left side of the workbench 2, and a plurality of cylinders 6 are arranged side by side on the side of the fixed seat 5 away from the positioning table 3, and the output shafts of the plurality of cylinders 6 are fixedly installed with clamping plates 7.

[0028] In this embodiment, the angle steel is placed from directly above the positioning platform 3, and the inner side of the angle steel abuts against the outer side of the positioning platform 3. Then, cylinder 6 is activated, and cylinder 6 controls the clamping plate 7 to push forward. After the clamping plate 7 pushes forward, it clamps the outer wall of the angle steel. In this way, when loading, the angle steel can be placed from directly above the top of the bending machine body 1, and when unloading, it can be removed from above the bending machine body 1. This makes loading and unloading more convenient and does not occupy too much operating space.

[0029] like Figure 2 and Figure 3 As shown, a pressure plate 4 is movably installed directly above the top of the positioning table 3. A linkage mechanism is provided between the pressure plate 4 and the clamping mechanism. The linkage mechanism includes a pressure rod 9, which is fixedly connected to the two outer ends of the pressure plate 4 on the side away from the clamping plate 7. The two ends of the worktable 2 near the pressure rod 9 are provided with rod grooves 10. The bottom end of the pressure rod 9 passes through the rod groove 10 and is fixedly connected to the second inclined block 11. The linkage mechanism also includes a guide groove 12. The worktable 2 near the bottom end of the clamping plate 7 is provided with guide grooves 12 on both sides. The bottom ends of both sides of the clamping plate 7 are provided with guide bars 13 that are slidably connected to the guide grooves 12. One side of the bottom end of the guide bar 13 is provided with an inclined block 14 that matches the second inclined block 11. The bottom end of the second inclined block 11 is provided with a bottom groove 15. A spring 16 is provided inside the bottom groove 15. The other end of the spring 16 is fixedly connected to the bending machine body 1.

[0030] In this embodiment, when the clamping plate 7 is driven forward, the clamping plate 7 will drive the guide bar 13 to slide inside the guide groove 12, and control the first inclined block 14 to move synchronously. When the first inclined block 14 moves, it presses down the second inclined block 11. When the second inclined block 11 is pressed down, it synchronously compresses the spring 16 at the bottom end, and drives the pressure plate 4 to descend through the pressure rod 9, clamping the other side of the angle steel to the upper end face of the positioning table 3. In this way, the pressure plate 4 and the clamping plate 7 can be controlled by the cylinder 6 to clamp and fix both sides of the angle steel at the same time, thereby achieving the purpose of energy saving.

[0031] like Figure 4 As shown, a bending mechanism is provided on the outside of the worktable 2 near the clamping mechanism and the positioning table 3 in the same direction. The bending mechanism includes a frame 17, which is located on the side of the worktable 2 near the clamping plate 7. A second cylinder 18 is fixedly installed on the back of the frame 17. A push block 19 is fixedly connected to the output shaft of the second cylinder 18. A slide groove 8 is provided on the worktable 2 near the bottom of the push block 19. The bottom middle of the push block 19 is slidably connected to the slide groove 8.

[0032] In this embodiment, after the angle steel is clamped, cylinder 2 18 is activated. Cylinder 2 18 controls push block 19 to push forward. When push block 19 pushes forward, the angle steel is positioned by positioning table 3, so the position of the angle steel extending out of positioning table 3 is bent to 90° by push block 19.

[0033] Working principle: During processing, the angle steel is placed directly above the positioning table 3, with the inner side of the angle steel abutting against the outer side of the positioning table 3. Then, cylinder 6 is activated, which controls the clamping plate 7 to push forward. After the clamping plate 7 is pushed forward, it clamps the outer wall of the angle steel. When the clamping plate 7 is driven forward, it will drive the guide bar 13 to slide inside the guide groove 12 and control the inclined block 14 to move synchronously. When the inclined block 14 moves, it presses down the inclined block 2 11. When the inclined block 2 11 is pressed down, it synchronously compresses the spring 16 at the bottom end, and drives the pressure plate 4 to descend through the pressure rod 9, clamping the other side of the angle steel to the upper end face of the positioning table 3. This makes clamping the angle steel more stable and convenient. After the angle steel is clamped, cylinder 18 is activated, which controls the push block 19 to push forward. When the push block 19 pushes forward, because the angle steel is positioned by the positioning table 3, the part of the angle steel that extends out of the positioning table 3 is bent to 90° by the push block 19.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
