Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically to a wire cutting device that is easy to position. Background Technology

[0002] Wire rod refers to hot-rolled round steel or similar shaped steel. Because it is delivered in coil form, it is also commonly known as wire rod. Wire rod has a very small circumference. Depending on the rolling mill, it can be divided into high-speed wire rod and ordinary wire rod. Wire rod is generally made of ordinary carbon steel and high-quality carbon steel. According to the steel allocation catalog and different uses, wire rod includes ordinary low-carbon steel hot-rolled round wire rod, high-quality carbon steel wire rod, carbon welding rod wire rod, quenched and tempered threaded wire rod, wire rod for making steel wire rope, wire rod for piano wire, and stainless steel wire rod, etc.

[0003] The raw materials are all coiled materials. Before being used as workpieces, the coiled materials must be cut into segments according to the required length. Traditional wire cutting processes are generally done manually, which is inefficient, costly, and cannot perform cyclical fixed-length cutting. At the same time, it is not convenient to continuously position the wire during the cutting process, which makes the wire easy to lift up when moving and cutting, affecting the stability of the cutting process. Therefore, it is necessary to provide a new wire cutting device that is easy to position to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a wire cutting device that is easy to position, has the advantages of continuous cyclic cutting of fixed length, easy adjustment of positioning and compaction to prevent warping, and solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting device for easy positioning, comprising: an operating table, with two limiting posts and a fixed frame fixedly connected to the top of the operating table; a sliding plate slidably connected inside the two limiting posts; a cutting blade fixedly connected to the bottom of the sliding plate; a connecting plate fixedly connected to the outside of the sliding plate; two rotating shafts rotatably connected to the top of the connecting plate; a servo motor fixedly connected to the top of each of the two rotating shafts; a limiting plate slidably connected inside the fixed frame; a screw rotatably connected to the top of the limiting plate; a sleeve fitted at the bottom of the limiting plate; a sliding frame fixedly connected to the bottom of the sleeve; and a pressing wheel rotatably connected inside the sliding frame. In use, the wire is fed through the fixed frame via a conveying mechanism and simultaneously conveyed towards the cutting blade. During cutting, the wire is controlled by the servo motor... The machine drives the rotating shaft to rotate, which, through the centrifugal shaft, repeatedly pulls the connecting plate. This causes the connecting plate to drive the sliding plate to slide up and down repeatedly inside the limiting post. Simultaneously, the sliding plate drives the cutting blade to move up and down repeatedly, further realizing the cutting operation of the wire. During the cutting process, the conveyor speed and the servo motor rotation speed are constant, which can ensure that the interval of the cutting blade's repeated up and down cutting is constant. This ensures that the wire is cut to a fixed length each time, achieving a fixed-length cut. Compared with the traditional method of measuring first and then cutting, it is more efficient. At the same time, during the process of feeding the wire to the cutting blade, the crushing roller can squeeze the wire to prevent the wire from warping during the cutting process, improving the stability of the cutting process. Meanwhile, by rotating the screw, the wire can be raised and lowered inside the fixed frame, and the height of the limiting plate, sleeve, and sliding frame can be adjusted simultaneously to adjust the squeezing force of the crushing roller on the wire.

[0006] Preferably, each of the two limiting posts has a slot inside, and the sliding plate is locked inside the two slots. The slot can limit the sliding trajectory of the sliding plate, so that the sliding plate can drive the cutting blade to move vertically up and down.

[0007] Preferably, both of the limiting posts have sliding grooves on their outer surfaces, and the connecting plate is engaged inside the two sliding grooves. The sliding grooves allow the connecting plate to slide smoothly up and down along the outer surfaces of the two limiting posts.

[0008] Preferably, the two servo motors are fixedly connected to the top of the two limit posts. The two servo motors can synchronously drive the two rotating shafts to rotate centrifugally, so that when the rotating shafts rotate centrifugally, they can pull the connecting plate to cyclically rise and fall between the low and high positions, and further control the cutting blade to cut the wire.

[0009] Preferably, the fixed frame has a limiting groove inside, the limiting plate is locked inside the limiting groove, the screw is movably connected to the top of the limiting plate, and the screw is threadedly connected to the inside of the fixed frame. The limiting groove can limit the sliding trajectory of the limiting plate, and the screw can be rotated to move up and down along the internal thread of the fixed frame, further adjusting the squeezing force of the crushing wheel on the wire.

[0010] Preferably, a turntable is fixedly connected to the top of the screw, and a return spring is sleeved inside the sleeve. The return spring allows the crushing wheel to elastically compress the wire, avoiding rigid compression and improving the protection of the wire.

[0011] Preferably, the bottom of the operating table is fixedly connected to four base columns, and the bottom of each of the four base columns is fixedly connected to a rubber pad. The base columns can provide stable support for the entire device and improve the stability of the entire device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. In use, the wire is conveyed through the conveying mechanism and passed through the fixed frame towards the cutting blade. During cutting, the servo motor drives the rotating shaft to rotate. The rotating shaft, through the centrifugal shaft, can repeatedly pull the connecting plate, causing the connecting plate to drive the sliding plate to slide up and down repeatedly inside the limiting post. Simultaneously, the sliding plate drives the cutting blade to move up and down repeatedly, further realizing the cutting operation of the wire. During the cutting process, the conveyor speed and the servo motor rotation speed are constant, which can realize a constant interval for the cutting blade to repeatedly cut up and down. This ensures that the wire is cut to a constant length each time, achieving a fixed-length cut, which is more efficient than the traditional method of measuring first and then cutting.

[0014] II. In this utility model, during the feeding of the wire to the cutting blade, the wire can be squeezed by the crushing roller, which prevents the wire from warping during the cutting process and improves the stability of the cutting process. At the same time, by rotating the screw, the wire can be raised and lowered inside the fixed frame, and the height of the limiting plate, sleeve and sliding frame can be adjusted simultaneously to realize the adjustment of the crushing force of the crushing roller on the wire.

[0021] 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.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a wire cutting device for easy positioning, comprising: an operating table 1, with two limiting posts 3 and a fixed frame 4 fixedly connected to the top of the operating table 1; a sliding plate 5 slidably connected inside the two limiting posts 3; a cutting blade 6 fixedly connected to the bottom of the sliding plate 5; a connecting plate 19 fixedly connected to the outside of the sliding plate 5; two rotating shafts 12 rotatably connected to the top of the connecting plate 19; a servo motor 11 fixedly connected to the top of each of the two rotating shafts 12; a limiting plate 15 slidably connected inside the fixed frame 4; a screw 16 rotatably connected to the top of the limiting plate 15; a sleeve 14 sleeved at the bottom of the limiting plate 15; a sliding frame 7 fixedly connected to the bottom of the sleeve 14; and a pressing wheel 8 rotatably connected inside the sliding frame 7. In use, the wire is fed through the fixed frame 4 via a conveying mechanism and simultaneously conveyed towards the cutting blade 6. During cutting, the servo motor 11 drives the rotating shafts 12 to rotate, and the rotating shafts 12, through a centrifugal shaft, repeatedly pull the connecting plate 19, causing the connecting plate 19 to move the sliding plate 5. The limiting post 3 slides up and down repeatedly inside, and the synchronous sliding plate 5 drives the cutting blade 6 to move up and down repeatedly, further realizing the cutting operation of the wire. During the cutting process, the conveyor speed is constant and the rotation speed of the servo motor 11 is constant, which can realize that the interval of the cutting blade 6 repeatedly cutting up and down is constant. This ensures that the wire is cut to a constant length each time, which is more efficient than the traditional method of measuring first and then cutting. At the same time, during the process of the wire being conveyed to the cutting blade 6, the crushing roller 8 can squeeze the wire to prevent the wire from warping during the cutting process and improve the stability of the cutting process. Meanwhile, by rotating the screw 16, it can be raised and lowered inside the fixed frame 4, and the height of the limiting plate 15, sleeve 14 and sliding frame 7 can be adjusted simultaneously to realize the adjustment of the crushing force of the crushing roller 8 on the wire. Both limiting posts 3 have slots 9 inside, and the sliding plate 5 is locked in the two slots 9. The slots 9 can limit the sliding trajectory of the sliding plate 5, so that the sliding plate 5 can drive the cutting blade 6 to move up and down vertically.

[0023] Both limiting posts 3 have grooves 10 on their outer sides, and the connecting plate 19 is locked inside the two grooves 10. The grooves 10 allow the connecting plate 19 to slide smoothly up and down along the outer side of the two limiting posts 3.

[0024] Two servo motors 11 are fixedly connected to the top of two limit posts 3 respectively. The two servo motors 11 can synchronously drive the two rotating shafts 12 to rotate centrifugally. When the rotating shafts 12 rotate centrifugally, they can pull the connecting plate 19 to cyclically rise and fall between low and high positions. Furthermore, the cutting blade 6 can be controlled to cut the wire.

[0025] The fixed frame 4 has a limiting groove 13 inside, and the limiting plate 15 is locked inside the limiting groove 13. The screw 16 is movably connected to the top of the limiting plate 15 and is threadedly connected to the inside of the fixed frame 4. The limiting groove 13 can limit the sliding trajectory of the limiting plate 15. The screw 16 can be rotated and raised and lowered along the internal thread of the fixed frame 4, and the extrusion force of the crushing wheel 8 on the wire can be adjusted.

[0026] A turntable 17 is fixedly connected to the top of the screw 16, and a return spring 18 is sleeved inside the sleeve 14. The return spring 18 allows the crushing wheel 8 to elastically squeeze the wire to avoid rigid squeezing and improve the protection of the wire.

[0027] When in use, the easy-to-position wire cutting device uses a servo motor 11 to drive the rotating shaft 12 to rotate. The rotating shaft 12, through the rotation of the centrifugal shaft, can repeatedly pull the connecting plate 19, causing the connecting plate 19 to drive the sliding plate 5 to slide up and down repeatedly inside the limiting post 3. Simultaneously, the sliding plate 5 drives the cutting blade 6 to move up and down repeatedly, further realizing the wire cutting operation. During the cutting process, the conveyor speed is constant and the rotation speed of the servo motor 11 is constant, which can realize that the interval of the cutting blade 6 repeatedly cutting up and down is constant, further ensuring that the wire is cut to a constant length each time.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a wire cutting device that is easy to position. The bottom of the operating table 1 is fixedly connected to four base columns 2, and the bottom of each of the four base columns 2 is fixedly connected to a rubber pad. The base columns 2 can provide stable support for the whole device and improve the stability of the whole device.

[0029] When in use, the wire cutting device that is easy to position can squeeze the wire through the rolling roller 8 to prevent the wire from sticking up during the cutting process and improve the stability of the cutting process. At the same time, by rotating the screw 16, it can raise and lower the screw inside the fixed frame 4, and simultaneously control the height adjustment of the limit plate 15, sleeve 14 and sliding frame 7.
