Description

Technical Field

[0001] This utility model relates to the technical field of angle steel punching devices, specifically, to an angle steel punching device. Background Technology

[0002] Angle steel is widely used in the manufacture of power transmission towers. During production, holes need to be punched into the angle steel according to assembly requirements. Angle steel punching devices utilize hydraulic presses to punch holes in the angle steel. Existing punching technologies include traditional die punching and more automated CNC punching. CNC punching equipment offers high punching accuracy, but its procurement cost is higher. Traditional die punching requires manual handling of the angle steel onto the die, followed by adjustment to the appropriate position before punching. When processing large angle steels, due to their weight, manual handling is time-consuming and labor-intensive, and adjusting the angle steel's position is difficult. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an angle steel punching device, which solves the technical problems of difficulty in feeding and adjusting the position of large angle steel in traditional punching devices.

[0004] According to one aspect, at least one embodiment of the present invention provides an angle steel punching device, comprising: frame; The lower mold is mounted on the frame, and the top of the lower mold is used to support the angle steel. The upper mold is lifted and mounted on the frame. The upper mold can be lowered to approach the lower mold and punch holes in the angle steel on the lower mold. There are at least two rotating conveyor wheels, which are respectively rotatably arranged on both sides of the frame. The end face and circumferential surface of the rotating conveyor wheel are respectively used to abut against the two sides of the angle steel. The circumferential surface of the rotating conveyor wheel is not lower than the top of the lower mold.

The lifting frame is configured such that when the upper mold presses down on the angle steel, the lifting frame is pressed down by the angle steel so that one side of the angle steel abuts against the top of the lower mold.

[0006] For example, in at least one embodiment of the present invention, an angle steel punching device further includes: The elastic element has two ends acting on the support frame and the lifting frame respectively. The elastic element is used to elastically push the lifting frame to drive the rotating conveyor wheel to rise.

[0007] For example, in at least one embodiment of the present invention, an angle steel punching device further includes: A sliding member is slidably mounted on the frame. The sliding member can slide close to the lower mold, and a limiting space is formed between the sliding member and the lower mold. The limiting space is used to position one side of the angle steel so that the two sides of the angle steel abut against the top and side of the lower mold, respectively.

[0008] For example, in at least one embodiment of the present invention, an angle steel punching device is provided, wherein the lower die is planar at one end near the sliding member.

[0009] For example, in at least one embodiment of the present invention, an angle steel punching device further includes: A screw is rotatably mounted on the frame, and the screw is threadedly connected to the slider, which is used to drive the slider to slide.

[0014] The beneficial effects of the embodiments of this utility model are as follows: In this invention, a rotating conveyor wheel is added to the traditional punching device. This wheel primarily transports the angle steel to the lower die, and during transport, the end face and circumference of the wheel abut against the angle steel to achieve positioning and adjustment. The rotation of the conveyor wheel allows the operator to smoothly push the angle steel from the feed end to the top of the lower die, reducing manual handling workload. Simultaneously, the contact between the end face and circumference of the conveyor wheel and the angle steel allows for precise positioning of the angle steel, ensuring the punched edge is accurately placed on the lower die. This solves the problems of difficulty in punching and adjusting the position of large angle steel using a traditional punching device. Attached Figure Description

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] For ease of description, the two sides of an angle steel with a certain angle are defined as the punched side and the non-punched side.

[0024] like Figures 1-5As shown, this invention illustrates an angle steel punching device according to one embodiment, comprising a frame 100, a lower die 200, an upper die 300, and several rotating conveyor wheels 410. This design is an improvement on a conventional punch press. The frame 100 serves as the punch press frame, providing a mounting base for the upper die 300 and the lower die 200. During the punching process, the frame 100 can effectively disperse and bear the reaction force generated by the upper die 300 on the punching, ensuring the stability of the entire device during operation, avoiding component displacement or damage due to uneven force distribution, and ensuring punching accuracy.

[0025] The lower die 200 is mainly used to support the punching edge of the angle steel and cooperates with the upper die 300 to complete the punching of the punching edge of the angle steel. During punching, the upper die 300 moves downward and the punch enters the cavity of the lower die 200 to punch through the angle steel, thereby forming the required hole on the angle steel.

[0026] The upper die 300 is mounted on the frame 100 via a lifting mechanism. The top of the upper die 300 is connected to the lifting mechanism, and the bottom is equipped with a punch corresponding to the cavity of the lower die 200. The shape and size of the punch are determined according to the punching requirements, and the length is selected according to the thickness of the angle steel and the punching depth requirements. Driven by the lifting mechanism, the upper die 300 descends and approaches the lower die 200, punching holes in the angle steel on the lower die 200 through the punch.

[0027] At least two rotating conveyor wheels 410 are rotatably mounted on both sides of the frame 100. The rotating conveyor wheels 410 are made of hard plastic or nylon, which prevents scratches on the surface of the angle steel during transport and reduces transport noise. The rotating conveyor wheels 410 are cylindrical in shape. The end face and circumferential surface of the rotating conveyor wheel 410 are used to abut against two sides of the angle steel. The end face abuts against the side of the non-punched edge of the angle steel, and the circumferential surface abuts against the bottom surface of the punched edge of the angle steel. The circumferential surface of the rotating conveyor wheel 410 is not lower than the top of the lower mold 200, and the end face is coplanar with the side of the lower mold 200 to ensure smooth transport of the angle steel onto the lower mold 200, with the side of the non-punched edge of the angle steel abutting against the side of the lower mold 200.

[0028] By adding a rotating conveyor wheel 410 to the traditional punching device, the angle steel is transported to the lower die 200. During transport, the end face and circumference of the wheel abut against the angle steel, enabling positioning and adjustment. The rotation of the wheel 410 allows the operator to smoothly push the angle steel from the feed end to the lower die 200, reducing manual handling. Simultaneously, the contact between the end face and circumference of the wheel 410 and the angle steel allows for precise positioning of the angle steel, ensuring the punched edge is accurately placed on the lower die 200. This solves the problems of difficult feeding and positioning of large angle steel when using a traditional punching device.

[0029] In some examples, a support frame 420 and a lifting frame 430 are also included. There are at least two support frames 420, the number of which matches the number of rotating conveyor wheels 410. The support frames 420 provide a stable mounting base for the lifting frame 430 and the rotating conveyor wheels 410. The lifting frame 430 engages with the smooth rod on the support frame 420 through a limiting hole to achieve lifting movement. The lifting frame 430 has a rectangular frame structure. The rotating conveyor wheels 410 are cantilevered and rotatably mounted on the lifting frame 430, so that the end face of the rotating conveyor wheels 410 facing away from the lifting frame 430 can abut against the side of the non-punched edge of the angle steel.

[0030] After the rotating conveyor wheel 410 transports the angle steel to above the lower die 200, the upper die 300 presses down on the angle steel. The angle steel transmits pressure to the rotating conveyor wheel 410, which in turn causes the lifting frame 430 to descend. This ensures that one side of the angle steel is in close contact with the top of the lower die 200, achieving accurate positioning and stable support for the angle steel during punching. The structure, with the circumferential surface of the rotating conveyor wheel 410 at a height no lower than the top of the upper die 300, allows the angle steel to be easily pushed so that the punched edge is above the upper die 300. Furthermore, when the upper die 300 performs the punching action, the lifting frame 430 descends to avoid damaging the rotating conveyor wheel 410.

[0031] In some examples, an elastic element 440 is also included. The elastic element 440 can be a high-strength spring, such as a helical compression spring. The main function of the elastic element 440 is to provide an upward elastic thrust for the lifting frame 430. After the punching operation is completed and the upper die 300 rises, the elastic element 440 can quickly push the lifting frame 430 to drive the rotating conveyor wheel 410 to rise, returning it to its initial position and preparing it for moving the angle steel.

[0032] The elastic element 440 can quickly push the lifting frame 430 to reset. Compared with manual or other slower reset methods, the reset time of the lifting frame 430 after each punching can be shortened by about 30%-50%, which helps to improve the working efficiency of the equipment.

[0033] In some examples, a slider 510 is also included. The slider 510 is slidably mounted on the frame 100 via a linear guide pair. The side of the slider 510 closest to the lower die 200 cooperates with the side of the lower die 200 to form a limiting space 520. The limiting space 520 is determined according to the thickness of the non-punched edge of the angle steel, ensuring that the non-punched edge of the angle steel can fit against the side of the lower die 200, thereby making the holes on the punched edge of the angle steel in a straight line.

[0034] The sliding component 510 can be adjusted to accommodate angle steel of different thicknesses by sliding and adjusting the distance between it and the side of the lower mold 200, thus improving the applicability of the lifting device.

[0035] In some examples, the side wall of the lower die 200 near the slider 510 is a flat surface. The flat surface is milled by the lower die 200. The flat surface can increase the contact area between the side of the lower die 200 and the non-punching side of the angle steel, thereby improving the stability of the angle steel during the punching process.

[0036] In some examples, a screw 530, rotatably mounted on the frame 100, is also included. The screw 530, through a threaded connection with the slider 510, converts its own rotation into linear motion of the slider 510, thereby controlling the position of the slider 510. When positioning the angle steel is required, rotating the screw 530 allows the slider 510 to smoothly move closer to or further away from the lower die 200 along the linear guide pair on the frame 100, thus adjusting the size of the limiting space 520 and achieving the positioning of the angle steel. This driving method provides stable and precise displacement control. Compared to other driving methods, such as simple manual pushing or simple linkage mechanisms, the screw 530 drive can more accurately adjust the position of the slider 510, improving the positioning accuracy of the angle steel and ensuring the accuracy of the punching position.

[0037] In some examples, the slider 510 includes a main body 511 and a rotating block 512. The main body 511 is rectangular in shape, and a slider that mates with the linear guide rail of the frame 100 is mounted on the bottom of the main body 511, ensuring that the main body 511 can slide smoothly along the guide rail. The main body 511 is provided with a threaded hole that matches the screw 530, ensuring a tight threaded connection with the screw 530, thereby enabling the screw 530 to drive the main body 511 to slide.

[0038] The main body 511 serves as the basic structure of the sliding component 510, supporting the rotating block 512. Through a threaded connection with the screw 530, it slides along the frame 100 under the drive of the screw 530. It converts the rotational motion of the screw 530 into linear motion, causing the rotating block 512 to move closer to or further away from the lower mold 200, thereby adjusting the size of the limiting space 520 and providing a basic displacement adjustment function for the positioning of the angle steel.

[0039] The rotating block 512 is cylindrical and can be directly inserted into the main body 511, ensuring that the rotating block 512 can rotate relative to the main body 511. The circumferential surface of the rotating block 512 and the side of the lower mold 200 form a limiting space 520. The circumferential surface of the rotating block 512 can guide the angle steel. When the front end of the angle steel is about to enter the limiting space 520, the non-punched edge of the angle steel enters the limiting space 520 under the action of the circumferential surface of the rotating block 512. After the non-punched edge of the angle steel enters the limiting space 520, the position of the angle steel needs to be moved so that the friction between the angle steel and the rotating block 512 can drive the rotating block 512 to rotate, thereby reducing the wear of the rotating block 512 and improving the service life of the device.

[0040] In some examples, the rotating block 512 is detachably mounted on the main body 511. Specifically, a cylinder is welded onto the main body 511, and the rotating block 512 has two sections with different diameters. The first section with a smaller diameter can be inserted into the cylinder, which restricts the rotating block 512 while allowing the first section to rotate freely inside the cylinder. The second section with a larger diameter cannot enter the cylinder because its diameter is larger than that of the cylinder, and the circumferential surface of the second section forms a limiting space 520 with the side of the lower mold 200.

[0041] In some examples, the lower die 200 is detachably mounted on the frame 100. In another example, the lower die 200 is fixed to the frame 100 by bolts. By changing the die, it can be adapted to different angle steels and different punching size requirements.

[0042] In some examples, the upper mold 300 includes a lifting seat 310, a stamping part 320, and a rubber ring 330. The lifting seat 310 is connected to the frame 100 via a linear guide pair or a hydraulic lifting mechanism to achieve lifting movement. If a linear guide pair is used, the guide rail is fixed on the frame 100, and the sliders are installed on both sides of the lifting seat 310 to ensure smooth lifting of the lifting seat 310, with straightness error controlled within 0.05 mm per meter. If a hydraulic lifting mechanism is used, the cylinder body of the hydraulic cylinder is fixed on the frame 100, and the piston rod is connected to the lifting seat 310. The lifting of the lifting seat 310 is controlled by the pressure of hydraulic oil. The lifting seat 310 is provided with mounting holes and positioning slots for accurate installation of the stamping part 320 and the rubber ring 330, ensuring their relative positional accuracy with the lifting seat 310.

[0043] The main function of the lifting seat 310 is to support the stamped part 320 and the rubber ring 330, and to move up and down under the action of the drive mechanism (linear guide pair or hydraulic lifting mechanism), thereby moving the stamped part 320 and the rubber ring 330 closer to or further away from the lower die 200. During the punching process, the lifting seat 310 provides stable support for the stamped part 320, enabling it to accurately cooperate with the lower die 200 to complete the punching operation of the angle steel. At the same time, the lifting seat 310 drives the rubber ring 330 to descend, thereby clamping the angle steel and ensuring its stability during punching.

[0044] The stamping part 320 can move downward under the drive of the lifting seat 310. The punch cooperates with the cavity of the lower die 200 to punch through the angle steel, thereby forming the required hole in the angle steel.

[0045] The rubber ring 330 is made of a highly elastic and wear-resistant rubber material, such as nitrile rubber or polyurethane rubber. The inner diameter of the rubber ring 330 is slightly larger than the outer diameter of the stamping part 320 to ensure it fits snugly onto the stamping part 320. The thickness of the rubber ring 330 is between 10-20 mm to ensure sufficient elastic deformation. The rubber ring 330 is fixed to the lifting seat 310 by interference fit or clamping to ensure it will not fall off during movement driven by the lifting seat 310. When the lifting seat 310 lowers the rubber ring 330, it first abuts against the angle steel on the lower die 200 and undergoes elastic deformation during further descent, thus tightly pressing the angle steel. The pressing action of the rubber ring 330 effectively prevents the angle steel from moving and swaying during the punching process, improving the accuracy and quality of the punching. Simultaneously, the elasticity of the rubber ring 330 also buffers the impact force generated by the stamping part 320 during punching, reducing damage to the punching equipment and extending its service life.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
