Technical Field

[0002] In the field of modern materials science, precision alloys, with their unique physical and chemical properties, play an indispensable role in numerous high-tech industries. Precision alloy wire, a specialty metal material with an ultra-low coefficient of expansion, is highly sought after in fields such as aerospace, energy, and electronics due to its outstanding performance. However, the production and processing of this wire requires cutting it into segments of varying lengths for storage, depending on its specific usage scenarios. This requires specialized wire cutting equipment.

[0003] To address this, Chinese patent number CN217451941U proposes an auxiliary stabilizing device for cutting precision wires. The precision wire is slidably connected between the eccentric wheel and the rotating wheel of the first mounting plate, so that the second mounting plate gradually moves away from the first mounting plate. When the precision wire reaches the required cutting length, the second mounting plate stops moving, and the eccentric wheel and rotating wheel on the first mounting plate clamp the precision wire. An electric push rod is used to push the blade to cut the precision wire.

[0004] However, when the above technical solution is used to cut precision wires, if the same batch of wires need to be cut to equal lengths, the device itself cannot automatically control the length of the cut wires. The staff needs to manually control the transfer distance of the wires, and then cut them through the cutting structure to achieve fixed-length cutting. The operation is very time-consuming and labor-intensive, and the staff needs to pay attention to the cutting process at all times, which increases the workload. In this regard, this design proposes an auxiliary cutting device for precision wire production. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: an auxiliary cutting device for precision wire production, comprising a cutting base 1 and a fixed-length cutting mechanism 2 and a traction mechanism 7, both of which are installed on the top of the cutting base 1 and distributed in the front and rear;

[0023] The fixed-length cutting mechanism 2 includes a first mounting frame 201 fixed to one side of the top of the cutting base 1, and both ends of one side of the first mounting frame 201 are rotatably connected to connecting bars 202, and one end of the two connecting bars 202 is rotatably connected to a guide roller 203, and both ends of the first mounting frame 201 are interpenetratingly connected with fixing bolts 204, and the outer walls of one end of the two fixing bolts 204 are respectively threadedly connected to the inner walls of the two connecting bars 202, and the top of the cutting base 1 is located on one side of the first mounting frame 201. An extension base 205 is installed, and a measuring groove 206 is provided in the middle position of the extension base 205. A positioning frame 207 is interpenetrated and connected to the inner wall of one end of the measuring groove 206, and a through groove 208 is provided at the bottom of the positioning frame 207. An infrared sensor 209 is installed on the upper side of the inner wall of the through groove 208, and a cutting blade 210 is slidably connected to the inner wall of the first mounting frame 201;

[0024] During use, the precision wire is transferred to the other end of the top of the cutting base 1 through the traction mechanism 7, and is guided by the guide roller 203 on the fixed-length cutting mechanism 2 so that it is transferred in the center. According to the diameter and thickness of the wire, the gap width between the guide rollers 203 is adjusted by rotating the connecting strips 202 on the first mounting frame 201, so that each wire can be squeezed by the guide rollers 203 during transfer, and the mutual rotation of the guide rollers 203 during transfer further assists the wire to be transferred to the rear side. After adjustment, the fixing bolt 204 is used to tighten the connecting strip 202 on the first mounting frame 201 to fix the position of the guide roller 203, and the wire is transferred to the extension base 205 in the center through the guide rollers 203. The wire rod 208 is moved straightly in the measuring slot 206 until the end of the wire rod is transferred to the through slot 208 at the bottom of the positioning frame 207 and passes through and blocks the infrared sensor 209, which can then issue a command to stop the operation of the motor 706. At the same time, the cylinder 212 starts to lower the cutting blade 210 and squeeze it on the wire rod to cut it off. According to the length requirement of the wire rod, the position of the positioning frame 207 is slidably adjusted in the measuring slot 206 by the first limiting slide 211, thereby changing the distance of its fixed-length sensing, so as to facilitate the fixed-length cutting control of wire rods with different length requirements. There is no need for the staff to pay attention to the cutting process all the time, and the automatic control of fixed-length cutting is realized, which improves the convenience of using the device and reduces the workload of the staff.

[0025] Furthermore, first limiting slots 211 are provided on both sides of the measuring slot 206 at the top of the extended base 205, and the outer walls of the two ends of the positioning frame 207 are slidably connected to the inner walls of the two first limiting slots 211 respectively. Bolts are threadedly connected on both sides of the top of the positioning frame 207. To meet the requirements of cutting different wire lengths, the positioning frame 207 can be slid in the first limiting slots 211 to change the position of the sensing wire length. After adjustment, the bolts are tightened to fix the position of the positioning frame 207.

[0026] Furthermore, a cylinder 212 is installed on the top of the first mounting frame 201, and support shafts 3 are inserted and connected in the middle position on both sides of the cutting blade 210. The bottoms of the two support shafts 3 are fixed with extrusion plates 4, and the outer walls of one end of the two support shafts 3 are sleeved with springs 5, and one end of the two springs 5 ​​is fixedly connected to the two sides of the cutting blade 210 respectively.

[0027] A connecting shaft 6 is fixedly provided at the middle position of the top of the cutting blade 210, and one end of the connecting shaft 6 passes through the top of the first mounting bracket 201 and is interlaced with the output end of the cylinder 212. After the cylinder 212 receives the command from the infrared sensor 209, it starts to extend the connecting shaft 6 to push the cutting blade 210 downward to cut the wire. During this process, the extrusion pieces 4 connected by the support shaft 3 on both sides of the blade first contact the two sides of the wire to be cut, and the spring 5 is compressed as the cutting blade 210 continues to descend so that the extrusion piece 4 squeezes and fixes the two ends. As the blade contacts the wire, the wire remains stable during the cutting process and is not easily deviated, so that the cut cross section of the wire is smoother, thereby improving the stability when cutting the wire.

[0028] Furthermore, the traction mechanism 7 includes a second mounting frame 701 installed on the top of the cutting base 1 and on the other side of the first mounting frame 201. Second limiting slide grooves 702 are provided on both sides of the inner wall of the second mounting frame 701. An electric push rod 703 is installed on the top of the second mounting frame 701. A lifting frame 704 is slidably connected between the inner walls of the four second limiting slide grooves 702. According to the thickness of the wire, the electric push rod 703 is started to slide and lift the lifting frame 704 in the second limiting slide groove 702 on the inner side of the second mounting frame 701 to adjust the gap between the traction shaft 705 and the cutting base 1, so as to facilitate the contact and extrusion transmission of wires of different thicknesses.

[0029] A traction shaft 705 is provided on the inner wall of the lifting frame 704 for rotation. One end of the traction shaft 705 passes through the outer wall of one side of the lifting frame 704 and is connected to a motor 706. The motor 706 and the cylinder 212 are electrically connected to the infrared sensor 209. The motor 706 that controls the rotation of the traction shaft 705 is controlled by the infrared sensor 209. When the wire blocks the infrared sensor 209, the motor 706 stops driving. At this time, the traction shaft 705 does not rotate to pull the wire, and the wire stops being transmitted, which facilitates the cutting blade 210 to cut.
