Description

Technical Field

[0001] The utility model discloses a device for bending a 60° angle steel, belonging to the technical field of metal processing. Background Art

[0002] Angle steel is widely used in ultra-high voltage transmission towers and communication towers, and mainly uses right-angle angle steel, that is, 90° angle steel; right-angle angle steel is produced by hot rolling process, which has the characteristics of high production efficiency and good quality stability. The triangular steel assembled with 60° angle steel has the characteristics of material saving and good anti-instability performance.

[0003] At present, the directional bending of angle steel workpieces is a job with great technical difficulty and high operation requirements in the processing process, and special equipment and technical means are required. However, the price of special large-scale equipment is expensive, and the equipment investment increases the production cost, which cannot meet the cost performance requirements of production equipment and benefits. Therefore, when processing 60° angle steel, production enterprises generally perform secondary bending processing on the existing 90° angle steel through stamping dies. When some existing stamping dies bend 90° angle steel by 60°, the processed angle steel is easy to get stuck in the die cavity, resulting in difficulty in taking out the processed angle steel and affecting the processing efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for bending a 60° angle steel to solve the above problems, which has the effect of conveniently taking out the processed angle steel from the die.

[0006] The utility model realizes the above purpose through the following technical solutions, including a machine base, a bending cavity is horizontally penetrated through the machine base, a downward pressing block that can move up and down is arranged at the upper end of the bending cavity, the lower end of the downward pressing block and the lower end of the bending cavity are both V-shaped structures with a 60° angle, a notch communicating with the bending cavity is opened at the front end of the machine base, the notch is opened at the lower side of the bending cavity, and a jacking mechanism is arranged in the notch. The jacking mechanism includes a jacking block, a telescopic rod and a fixing block. The fixing block is fixedly connected with the machine base. The jacking block is arranged above the fixing block and is connected with the fixing block through the telescopic rod. When the telescopic rod pushes the jacking block to move, the jacking block can extend into the bending cavity from the lower side of the bending cavity.

[0007] By adopting the above technical solution, the 90° angle steel is placed with the opening facing upwards in the bending cavity, and the lower pressing block is driven to move downwards. An acting force is applied to the angle steel through the lower pressing block. Under the shaping effect of the V-shaped structure with a 60° angle at the lower end of the lower pressing block and the lower end of the bending cavity, the angle steel is bent to form a 60° included angle. After the angle steel is bent in the bending cavity, the telescopic rod extends to push the jacking block to extend into the bending cavity from the lower side of the bending cavity, and the angle steel is jacked up from the lower side of the angle steel, so that the angle steel forms an inclined shape for easy removal from the bending cavity.

[0008] Preferably, front covers and rear covers are respectively arranged at the front and rear ends of the machine base. Through holes with the same shape as the bending cavity are opened in both the front cover and the rear cover. A limiting plate that can move up and down is arranged on the rear cover, and the limiting plate is arranged at the lower end of the through hole.

[0009] By adopting the above technical solution, the front cover can prevent sundries from entering the notch and affecting the operation of the jacking mechanism, and the limiting block on the rear cover can limit the position where the angle steel extends in, preventing one end of the angle steel from extending out from the rear end of the bending cavity when the angle steel is placed in the bending cavity and affecting the processing effect. At the same time, after the bending process is completed, the limiting plate can be lowered to take out the angle steel from the rear end.

[0010] Preferably, conveying devices are arranged on both the front and rear sides of the machine base. Both of the two conveying devices include V-shaped conveying frames and a plurality of conveying rollers. The two V-shaped conveying frames are respectively arranged on the front and rear sides of the machine base. One ends of the two V-shaped conveying frames respectively extend to the front and rear ends of the bending cavity, and the plurality of conveying rollers are rotatably arranged on two opposite inclined surfaces of the V-shaped conveying frames.

[0011] By adopting the above technical solution, the conveying device can convey the angle steel into the bending cavity and output the processed angle steel from the bending cavity. The angle steel is placed on the V-shaped conveying frame arranged on the front side of the machine base and pushed. By pushing the angle steel, the angle steel can be conveyed into the bending cavity through the conveying rollers. When the angle steel is processed, the limiting plate is lowered, and the angle steel can be taken out from the rear end of the machine base. The angle steel is output through the V-shaped conveying frame and the conveying rollers arranged at the rear end of the machine base.

[0012] Preferably, arc-shaped chamfers are arranged at the lower end of the lower pressing block and the lower end of the bending cavity.

[0013] By adopting the above technical solution, the arrangement of the arc-shaped chamfers can prevent the angle steel from breaking due to excessive force at the bent part when the lower pressing block and the bending cavity shape the angle steel.

[0014] Preferably, the upper end of the jacking block is a V-shaped structure with a 60° angle.

[0015] By adopting the above technical solution, the jacking block can fit the processed angle steel through the V-shaped structure with a 60° angle, so that the angle steel is evenly stressed when being jacked up, and the stability of jacking up the angle steel is improved.

[0016] Preferably, a hydraulic device is provided in the machine base, and the hydraulic device drives the lower pressing block, the telescopic rod and the limiting plate to move.

[0017] By adopting the above technical solution, through the setting of the hydraulic device, the movement of the lower pressing block, the telescopic rod and the limiting plate is more stable, and at the same time, the lower pressing block and the telescopic rod have sufficient power to bend and lift the angle steel.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] First, after the angle steel is bent in the bending cavity, the telescopic rod can drive the lifting block to lift the angle steel, so that the angle steel is in an inclined state, which is convenient for taking out the angle steel from the bending cavity, and prevents the situation that the angle steel is stuck in the bending cavity and is not easy to take out after being bent by force;

[0020] Second, the limiting plate on the rear cover plate can limit the angle steel to prevent the rear end of the angle steel from protruding from the rear end of the machine base, saving the step for workers to confirm the position of the angle steel after putting the angle steel into the bending cavity, and effectively improving the bending processing efficiency of the angle steel;

[0021] Third, the setting of the conveying device can improve the efficiency of the angle steel input and output in the bending cavity, save the time required for operating the angle steel, and further improve the processing efficiency;

[0022] Fourth, the arc-shaped chamfers provided at the lower end of the lower pressing block and the lower end of the bending cavity can effectively prevent the bending part of the angle steel from breaking due to excessive pressure, thereby improving the product production yield.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] A device for bending a 60° angle steel, as Figures 1-4 shown, includes a machine base 1. A bending cavity 2 is horizontally penetrated through the machine base 1. An upper pressing block 3 that can move up and down is arranged at the upper end of the bending cavity 2. The lower end of the upper pressing block 3 and the lower end of the bending cavity 2 are both V-shaped structures with a 60° angle. Place the 90° angle steel with the opening facing upwards in the bending cavity 2, drive the upper pressing block 3 to move downwards, apply a force to the angle steel through the upper pressing block 3, and under the shaping action of the V-shaped structures with a 60° angle at the lower end of the upper pressing block 3 and the lower end of the bending cavity 2, the angle steel is bent to form a 60° included angle. A notch communicating with the bending cavity 2 is opened at the front end of the machine base 1. The notch is opened at the lower side of the bending cavity 2. A jacking mechanism is arranged in the notch. The jacking mechanism includes a jacking block 4, a telescopic rod 5, and a fixing block 6. The fixing block 6 is fixedly connected to the machine base 1. The jacking block 4 is arranged above the fixing block 6 and is connected to the fixing block 6 through the telescopic rod 5. When the telescopic rod 5 pushes the jacking block 4 to move, the jacking block 4 can extend into the bending cavity 2 from the lower side of the bending cavity 2. After the angle steel is bent in the bending cavity 2, the telescopic rod 5 extends and pushes the jacking block 4 to extend into the bending cavity 2 from the lower side of the bending cavity 2, jack up the angle steel from the lower side of the angle steel, so that the angle steel forms an inclined shape, which is convenient for taking out from the bending cavity 2.

[0030] The front and rear ends of the machine base 1 are respectively provided with a front cover plate 7 and a rear cover plate 8. Both the front cover plate 7 and the rear cover plate 8 are provided with a through hole with the same shape as the bending cavity 2. The rear cover plate 8 is provided with a limit plate 9 which can move up and down. The limit plate 9 is arranged at the lower end of the through hole. The front cover plate 7 can prevent debris from entering the gap and affecting the work of the jacking mechanism, and the limit block on the rear cover plate 8 can limit the angle steel extension position to prevent one end of the angle steel from extending from the rear end of the bending cavity 2 when the angle steel is placed in the bending cavity 2 and affecting the processing effect. At the same time, after the bending process is completed, the limit plate 9 can be lowered to take out the angle steel from the rear end. Conveying devices are arranged on the front and rear sides of the machine base 1. The two conveying devices include a V-shaped conveying frame 10 and a plurality of conveying rollers 11. Two V-shaped conveying frames 10 are respectively arranged on the front and rear sides of the machine base 1, and one end of the two V-shaped conveying frames 10 extends to the front and rear ends of the bending cavity 2 respectively. A number of conveying rollers 11 can be rotatably arranged on two opposite inclined surfaces of the V-shaped conveying frames 10. The conveying device can transfer the angle steel to the bending cavity 2 and output the processed angle steel from the bending cavity 2. The angle steel is placed on the V-shaped conveying frame 10 arranged on the front side of the machine base 1 and pushed. The angle steel can be conveyed to the bending cavity 2 through the conveying rollers 11 by pushing the angle steel. When the angle steel is processed, the limit plate 9 is lowered to take out the angle steel from the rear end of the machine base 1, and the angle steel is output through the V-shaped conveying frame 10 and the conveying rollers 11 arranged at the rear end of the machine base 1.

[0031] The lower end of the pressing block 3 and the lower end of the bending cavity 2 are both provided with arc-shaped chamfers. The setting of the arc-shaped chamfers can prevent the bending part of the angle steel from being subjected to greater force and breaking when the pressing block 3 and the bending cavity 2 are bending and shaping the angle steel. The upper end of the lifting block 4 is a V-shaped structure with a 60° angle. The lifting block 4 can fit the angle steel after processing through the 60° V-shaped structure, so that the angle steel is subjected to uniform force when being lifted up, thereby improving the stability of the lifted angle steel. A hydraulic device is provided in the machine base 1, which drives the pressing block 3, the telescopic rod 5 and the limit plate 9 to move. Through the setting of the hydraulic device, the activities of the pressing block 3, the telescopic rod 5 and the limit plate 9 are more stable. At the same time, the pressing block 3 and the telescopic rod 5 have sufficient power to bend and lift the angle steel.

[0032] When the angle steel is to be processed, the angle steel to be processed is placed on the V-shaped conveying frame 10 arranged on the front side of the machine base 1, and the angle steel is pushed so that it slides into the bending cavity 2 under the action of the conveying roller 11. At the same time, the limit plate 9 abuts against the rear end of the angle steel to prevent the rear end of the angle steel from extending out of the bending cavity 2, and then the pressing block 3 is pressed down by the hydraulic device to bend the angle steel. After the angle steel is processed, the hydraulic device drives the telescopic rod 5 to extend and the limit plate 9 to descend, so that the lifting block 4 lifts the front end of the angle steel. The angle steel is in an inclined state and the rear end slides into the V-shaped conveying frame 10 arranged at the rear end of the machine base 1 under the action of gravity, so that the angle steel can be easily taken out, thereby improving the processing efficiency of the angle steel bending process.
