Description

Technical Field

[0001] This utility model belongs to the field of round steel production technology, and in particular relates to a round steel cutting device for a round steel production line. Background Technology

[0002] After the round steel products are cut into sections, they are collected into groups by the cooling bed unloading device and sent to the output roller conveyor. The output roller conveyor then sends them to the fixed-length shearing to produce fixed-length finished products. Because of the mechanical properties of the round steel material, the stress distribution during the shearing process, and the shearing process itself, the round steel deforms during the section shearing. Therefore, upon reaching the fixed-length shearing position, the round steel needs to be transported to the fixed-length baffle for alignment before returning to the fixed-length shearing to cut off the deformed blank before continuing to cut to the fixed length to produce finished products. However, the process of conveying steel to the fixed-length baffle, aligning it completely, and then retracting it to the fixed-length shearing head is time-consuming and affects production efficiency. Furthermore, when cutting the round steel with fixed-length shears, the tearing and stress during the shearing process easily create burrs on the cut surface, affecting the quality of the round steel and requiring manual post-processing. Using fixed-length shears for round steel increases the frequency of shear operation and maintenance, and fixed-length shears are generally large pieces of equipment, making maintenance difficult.

[0003] Therefore, we propose a round steel cutting device for a round steel production line to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a round steel cutting device for a round steel production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A round steel cutting device for a round steel production line includes a shearing body, a working platform within the shearing body, a cutting platform and a continuous V-shaped toothed groove mounted on the working platform, a hydraulic cylinder mounted on the shearing body, an upper shearing blade mounted at the bottom of the hydraulic cylinder, a perforated lower shearing blade mounted on the cutting platform, the perforated upper shearing blade of the upper shearing blade being located above the perforated lower shearing blade, a waste chute mounted at the front end of a front elastic support device, the waste chute being arc-shaped and inclinedly disposed inside the shearing body, and a collection hopper mounted at the rear bottom of the shearing body, the other end of the waste chute being guided to the collection hopper.

[0006] Preferably, the shear blade includes a connecting block, a clamping device, a perforated shear blade, several bolts, and an upper blade holder. The connecting block is disposed on the top of the piston rod of the hydraulic cylinder, and the perforated shear blade is fixedly disposed on the bottom of the piston rod of the hydraulic cylinder. Several nuts are installed on the side wall of the connecting block, and several bolts pass through several nuts respectively. The other ends of several bolts are fixedly connected to the top of the clamping device respectively. The perforated shear blade moves through the side wall of the clamping device. Several slots are opened at the bottom of the clamping device, and the lower blade holder is used to fix the perforated shear blade.

[0007] Preferably, the position of the rear support guide groove of the cutting platform is located at the slot at the bottom of the clamping device and corresponds one-to-one with the position of the rear support guide groove. The cutting platform is also provided with a cutting groove, which is located directly below the blade on the hole-shaped shear blade.

[0008] Preferably, each of the bolts is surrounded by a telescopic spring, one end of which is fixedly connected to the top of the clamping device and the other end is fixedly connected to the bottom of the connecting block.

[0009] Preferably, the height of the lower blade of the perforated shear blade is consistent with the height of the rear support guide groove and the front elastic support device.

[0010] In summary, the technical effects and advantages of this utility model are as follows: The drive device in this application uses hydraulics, which is easier to control than mechanical devices. The overall device is smaller, and before the serrated shear blade cuts the round steel, the clamping device will fix the round steel in the current position to prevent the round steel from jumping during cutting and ensure the safe operation of the equipment. At the same time, since the serrated shear blade is more closely shaped to the round steel than the flat shear blade, it can effectively reduce burrs when cutting the round steel.

[0015] The bottom of the hydraulic cylinder 6 is equipped with an upper shear blade, and the cutting platform 3 is equipped with a lower shear blade 7 with a hole-shaped shear blade. The upper shear blade 12 with a hole-shaped shear blade is located above the lower shear blade 7 with a hole-shaped shear blade. The upper shear blade includes a connecting block 10, a clamping device 11, an upper shear blade 12 with a hole-shaped shear blade, several bolts 13, and an upper blade holder. The connecting block 10 is located on the top of the piston rod of the hydraulic cylinder 6, and the upper shear blade 12 with a hole-shaped shear blade is fixedly located on the bottom of the piston rod of the hydraulic cylinder 6. Several nuts 15 are installed on the side wall of the connecting block 10, and several bolts 13 pass through several nuts 15 respectively. The other end of several bolts 13 is fixedly connected to the top of the clamping device 11 respectively. The upper shear blade 12 with a hole-shaped shear blade moves through the side wall of the clamping device 11. Several slots 16 are opened at the bottom of the clamping device 11. The slots 16 can help the clamping device 11 fix the position of the round steel.

[0016] Several bolts 13 are surrounded by telescopic springs 18. One end of the telescopic spring 18 is fixedly connected to the top of the clamping device 11, and the other end is fixedly connected to the bottom of the connecting block 10. The force applied by the telescopic spring 18 to the clamping device 11 does not affect the piston rod of the oil cylinder 6 from driving the blade 12 on the hole-shaped shear blade to continue to move downward.

[0017] The position of the rear support guide groove 4 of the cutting platform 3 is located at the slot 16 at the bottom of the clamping device 11, which corresponds one-to-one with the position of the rear support guide groove 4.

A collection hopper 9 is installed at the bottom rear side of the shearing machine body 1. The other end of the waste chute 8 is guided to the collection hopper 9. The cut round steel billet can enter the collection hopper 9 along the waste chute 8 for convenient centralized processing by the staff. The height of the blade 7 under the hole-shaped shear is consistent with the height of the rear support guide groove 4 and the front elastic support device 5. The stepping cooling bed guides the round steel into the continuous V-shaped tooth groove 2 of the shear body 1, and the width of the continuous V-shaped tooth groove 2 is consistent with the width of the existing cooling bed line stationary tooth, thus facilitating the cutting operation.

[0019] The working principle is as follows: the round steel is conveyed to the shearing machine body 1 through the cooling bed and then placed on the cutting platform 3; The piston rod of the hydraulic cylinder 6 drives the blade on the shear blade to move downward. After the clamping device 11 clamps the round steel, the bolt 13 moves upward in the nut 15, which in turn compresses the telescopic spring 18. Then the blade 12 on the hole-shaped shear blade will cut off the round steel billet. The front end of the elastic support device 5 has a waste chute 8 at the front end, so the cut billet can be guided to the collection hopper 9 for centralized processing.
