Description

Technical Field

[0001] This utility model relates to the field of round steel processing technology, and specifically discloses a round steel shearing device. Background Technology

[0002] Round steel is a long strip of steel with a circular cross-section. According to its production process, it can be divided into three categories: hot-rolled, cold-drawn, and forged. Round steel is a common steel material in the machining industry, and due to its advantages such as convenient processing and high cost-effectiveness, it holds an irreplaceable position in industrial production. To meet the specification requirements of the machining industry for fixed-length materials, round steel needs to be cut to size. The raw material of round steel is mostly long, straight, or coiled, and needs to be cut according to the design dimensions for subsequent forging, cutting, or assembly. Cutting optimizes material utilization, reduces waste, and lowers processing costs. At the same time, cutting off defective ends improves the quality of the finished product, and the ability to flexibly adjust the length of components on the construction site also relies on efficient cutting technology.

[0003] Currently, round steel cutting operations mostly employ equipment such as shearing machines or high-speed saws. The round steel is manually placed inside the shearing machine, and the cutting is completed quickly while ensuring a smooth cut surface. This existing technology is inefficient, relying on manual operation of the shearing tools, which is time-consuming and unsuitable for batch processing, especially when handling large-diameter or high-hardness materials. Secondly, precision is difficult to guarantee; uneven manual force can easily lead to slanted cuts, burrs, or dimensional deviations, affecting subsequent assembly or machining quality and even causing material waste. Therefore, round steel processing suffers from high labor costs, low efficiency, and increased scrap rates, making it unsuitable for current round steel processing standards. Utility Model Content

[0004] In view of the problems of high labor costs and low processing efficiency in the current round steel processing, this utility model provides a round steel shearing device.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A round steel shearing device includes a frame, a transfer frame at the top of the frame, multiple rollers rotatably mounted inside the transfer frame for transferring round steel, a support frame on the side of the frame, a first servo cylinder arranged parallel to the transfer frame at the top of the support frame, a second servo cylinder fixedly mounted at the piston rod end of the first servo cylinder, the piston rod of the second servo cylinder being perpendicular to the first servo cylinder and parallel to the rollers, a first fixing plate fixedly mounted at the piston rod end of the second servo cylinder, and a second fixing plate fastened to the support frame at the side of the second servo cylinder, the first fixing plate and the second fixing plate being used to securely clamp the round steel; a shearing cutter rotatably mounted at the top of the support frame, and a storage bin at the bottom of the support frame for storing the scrap material after the round steel is sheared.

[0007] Preferably, a servo motor is fixedly installed on the outer side of the transfer frame, and the output shaft of the servo motor is connected to the roller shaft drive.

[0008] Preferably, a mounting plate and a track plate are fixedly installed on the top of the support frame. The mounting plate and the track plate are arranged perpendicularly. The cylinder body of the first servo cylinder is fastened to the mounting plate. A sliding plate with sliding fit is provided on the track plate. A connecting block is fixedly installed on the sliding plate. The connecting block is fastened to the cylinder body of the second servo cylinder.

[0009] Preferably, a support plate is fixedly installed on the top of the support frame, and the support plate is arranged at the same height as the roller.

[0010] Preferably, a first hinge seat is installed on the top of the support frame, a tool loading seat is hinged on the first hinge seat, a rotating shaft is rotatably installed inside the tool loading seat, and the shearing tool is fixedly installed on the periphery of the rotating shaft.

[0011] Preferably, a vertical beam is fixedly installed on the side of the support frame, a second hinge seat is installed on the top side of the vertical beam, a third servo cylinder is hinged on the second hinge seat, a bracket is hinged to the piston rod end of the third servo cylinder, and the bracket is hinged to the tool loading seat.

[0012] Preferably, the support frame has a strip groove to facilitate the passage of the shearing tool.

[0013] Preferably, a barrier is fixedly installed on the support frame, and the barrier is arranged above the storage barrel.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The rollers in the transfer frame of this invention can horizontally transmit round steel, thereby saving position adjustment time during round steel processing. By setting up a cooperative structure of a first servo cylinder and a second servo cylinder, the arrangement position and distance between the first and second fixed plates can be flexibly adjusted, allowing the first and second fixed plates to clamp round steel of various outer diameters, thus ensuring stability during round steel processing and avoiding dimensional deviations. Furthermore, by setting up a shearing blade, the round steel is precisely sheared according to a preset size, and the remaining material falls into a storage bin for isolated storage and subsequent reuse in secondary production. This invention reduces reliance on manual operation, accelerates round steel processing efficiency, shortens the shearing time, adapts to batch processing needs, and further improves the processing accuracy of round steel. While avoiding material waste, it reduces the scrap rate of round steel processing, ensuring that the round steel processing meets production standards, thus having a very broad application prospect.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] This specific embodiment provides a round steel shearing device, such as... Figures 1-4 As shown, the system includes a platform 1, which is a triangular structure with two supporting legs at the bottom. A transfer frame 2 is mounted on top of the platform 1.

Multiple rollers 3 are rotatably mounted inside the transfer frame 2, with both ends of each roller 3 rotatably engaging with the transfer frame 2. A servo motor 11 is mounted on the outer side of one of the rollers 3, with its body firmly connected to the side of the transfer frame 2. The output shaft of the servo motor 11 is connected to the roller 3 via a coupling, thereby driving the roller 3 to rotate, facilitating the transfer of round steel bars within the transfer frame 2.

[0024] A support frame 4 is provided on the side of the platform 1. The platform 1 is located at the inlet end of the transfer frame 2, and the support frame 4 is located at the outlet end of the transfer frame 2. The support frame 4 is welded from multiple support beams, with three supporting legs at the bottom and a square support frame at the top, which is securely connected to the bottom of the support frame 4. A mounting plate 12 and a track plate 13 are fixedly installed on the top of the support frame 4; the mounting plate 12 is vertically arranged, and the track plate 13 is horizontally arranged, so that the mounting plate 12 and the track plate 13 are arranged perpendicularly. A first servo cylinder 5 is fixedly mounted on the mounting plate 12 facing the support frame 4. The cylinder body of the first servo cylinder 5 is tightly connected to the mounting plate 12. The piston rod of the first servo cylinder 5 is horizontally arranged and perpendicular to the roller shaft 3. A second servo cylinder 6 is fixedly connected to the end of the piston rod of the first servo cylinder 5. The cylinder body of the second servo cylinder 6 is tightly connected to the piston rod of the first servo cylinder 5. The piston rod of the second servo cylinder 6 is perpendicular to the piston rod of the first servo cylinder 5 and parallel to the roller shaft 3. A sliding plate 14 is provided on the track plate 13. A connecting block 15 is fixedly mounted on the sliding plate 14. The connecting block 15 is tightly connected to the cylinder body of the second servo cylinder 6. When the piston rod of the first servo cylinder 5 pushes the second servo cylinder 6, the sliding ability of the sliding plate 14 can be used to effectively support the second servo cylinder 6, thereby ensuring the stability of the second servo cylinder 6 during position adjustment.

[0025] A support plate 16 is fixedly installed on the top of the support frame 4. The support plate 16 is arranged at the same height as the roller 3. One end of the support plate 16 is close to the outlet end of the transfer frame 2. A first fixing plate 7 and a second fixing plate 8 are respectively arranged on both sides of the other end of the support plate 16. The first fixing plate 7 is fastened to the piston rod end of the second servo cylinder 6, and the second fixing plate 8 is fastened to the support frame 4. When the roller 3 transfers the round steel to the support plate 16, the arrangement position of the first fixing plate 7 is adjusted by the second servo cylinder 6 so that the first fixing plate 7 and the second fixing plate 8 clamp the round steel and fix it on the support plate 16.

[0026] A first hinge seat 17 is installed on the top of the support frame 4. The first hinge seat 17 is arranged on the side of the second fixed plate 8 facing away from the first fixed plate 7. A tool loading seat 18 is hinged inside the first hinge seat 17 via a pin. The tool loading seat 18 consists of a shell, a tool motor, and a rotating shaft. The rotating shaft is driven by the tool motor, thereby achieving high-speed rotation. A shearing tool 9 is fixedly fitted around the rotating shaft. The shearing tool 9 can rotate at high speed with the rotating shaft. The shell is arranged around the shearing tool 9 to protect it. A vertical beam 19 is fixedly installed on the side of the support frame 4. A second hinge seat 20 is installed on the top side of the vertical beam 19. A third servo cylinder 21 is hinged on the second hinge seat 20 via a pin. A bracket 22 is hinged to the piston rod end of the third servo cylinder 21 via a pin. One end of the bracket 22 is hinged to the piston rod of the third servo cylinder 21, and the other end of the bracket 22 is hinged to the shell of the tool loading seat 18. By controlling the extension and retraction stroke of the piston rod of the third servo cylinder 21, and under the transmission action of the bracket 22, the tool loading seat 18 is rotated under the support of the first hinge seat 17, thereby adjusting the arrangement height of the shearing tool 9, so that the shearing tool 9 cuts the round steel downwards.

[0027] The support frame 4 is provided with a strip groove 23 to facilitate the passage of the cutting tool 9. The strip groove 23 is arranged below the cutting tool 9, thereby facilitating the passage of the cutting tool 9 through the support frame 4 and providing movement space for the cutting tool 9.

[0028] In addition, a barrier 24 is fixedly installed on the support frame 4, and the barrier 24 is arranged on the outside of the strip groove 23; a storage bucket 10 is provided at the bottom of the support frame 4, and the barrier 24 is arranged above the storage bucket 10, so as to facilitate the placement of the scrap material after the round steel is cut into the storage bucket 10.

[0029] The working principle of this utility model is as follows:

[0030] The operator can place the round steel into the transfer frame 2, and start the servo motor 11 to rotate the roller 3 connected to it, thereby transferring the round steel horizontally within the transfer frame 2, so that the head of the round steel is positioned above the pallet 16. By controlling the first servo cylinder 5, the position of the second servo cylinder 6 is adjusted. By controlling the second servo cylinder 6, the first fixing plate 7 is brought closer to the round steel, and under the support of the second fixing plate 8, the first fixing plate 7 and the second fixing plate 8 clamp the round steel onto the pallet 16. By controlling the stroke of the piston rod of the third servo cylinder 21, the tool loading seat 18 is hinged and rotated on the first hinge seat 17, thereby causing the shearing tool 9 to gradually approach the round steel. Under the rotation of the shearing tool 9, the round steel is cut according to the preset size. The scrap material after the round steel is cut can fall into the storage bucket 10 through the support frame 4, thereby isolating and storing it for subsequent secondary production.
