However, the temperature of the copper rod is high during the cutting process, which makes it difficult to position it manually. The cutting size is prone to errors, thus affecting the quality of the final product. Utility Model Content

[0032] The following is combined with Figure 1-4 , the present application is further described in detail through specific embodiments.

[0033] A copper rod cutting device, such as Figure 1 and Figure 2 As shown, it includes a tool holder 1 and a limiter 2, and a cutting assembly for cutting a copper rod is arranged on the tool holder 1. A slide cylinder 21 is arranged on the limiter 2, and the slide cylinder 21 is arranged toward the tool holder 1. In a specific implementation, a limiter is fixedly connected to the slide of the slide cylinder 21, and the limiter can abut the copper rod during the sliding process.

[0034] like Figure 2 and Figure 3 As shown, a positioning seat 11 for pushing and feeding the copper rod is fixedly installed on the tool holder 1, and a guide block 17 is also fixedly installed on the upper side of the positioning seat 11 of the tool holder 1, and an inclined surface is provided on the guide block 17 and the inclined surface is arranged from the guide block 17 toward the positioning seat 11. In specific implementation, the copper rod is driven and continuously moves toward the positioning seat 11 under the guidance of the guide block 17, and continuously extends out of the positioning seat 11.

[0035] like Figure 1 and Figure 4 As shown, the limit member includes a limit rod 212 and a pedestal 211, and the pedestal 211 is fixedly mounted on the slide of the slide cylinder 21. The limit rod 212 is fixedly arranged on the pedestal 211 and arranged toward the tool holder 1, and the limit rod 212 is used to abut the copper rod. A displacement sensor 22 is arranged on the limit frame 2 corresponding to the slide cylinder 21. In specific implementation, the displacement sensor 22 is used to detect the displacement distance of the slide of the slide cylinder 21 and control the start and stop of the slide cylinder 21. After the displacement sensor 22 is set to a value, it can stop the pedestal 211 after it has moved a certain distance. Since the copper rod is continuously pushed out and the limit rod 212 abuts against the copper rod, the displacement distance of the pedestal 211 can be indirectly used as the extension distance of the copper rod, and the size of the copper rod to be cut can be determined accordingly.

[0036] like Figure 1 and Figure 2As shown, the cutting assembly includes a blade 121 and a driving member. The blade 121 is arranged at a position corresponding to the positioning seat 11, and the driving member is used to drive the blade 121 to move vertically along the tool holder 1. The cutting assembly also includes an upper tool holder 12 and a lower tool holder 13, and the blade 121 is fixedly arranged on the upper tool holder 12 and the lower tool holder 13, respectively. A guide rod 16 is fixedly arranged on the tool holder 1 corresponding to the upper tool holder 12 and the lower tool holder 13, and the upper tool holder 12 and the lower tool holder 13 are slidably connected to the guide rod 16, and the guide rod 16 is arranged vertically along the tool holder 1. The upper tool holder 12 and the lower tool holder 13 are arranged correspondingly, and the blade 121 is arranged facing each other. The driving member includes an upper oil cylinder 14 and a lower oil cylinder 15, and the piston rod of the upper oil cylinder 14 is fixedly connected to the upper tool holder 12, and the piston rod of the lower oil cylinder 15 is fixedly connected to the upper tool holder 12. In specific implementation, both sides of the upper oil cylinder 14 and the lower oil cylinder 15 are provided with guide rods 16, and the guide rods 16 are vertically arranged along the tool holder 1. The piston rods of the upper oil cylinder 14 and the lower oil cylinder 15 are also provided with sliders, which are fixedly connected to the piston rod and slidably connected to the guide rods 16. The displacement sensor 22 is installed on the guide rods 16. The upper oil cylinder 14 can drive the upper tool holder 12 to slide up and down along the tool holder 1, and the lower oil cylinder 15 can drive the lower tool holder 13 to slide up and down, so as to achieve the cutting of the copper rod. The blade 121 includes a powder high-speed steel blade 121, which can be made of 2012 powder high-speed steel. This blade 121 has good thermal processing performance and is not easy to be deformed or damaged when in contact with the copper rod with a temperature of up to 600 degrees. In other embodiments, the blade 121 can also be made of other materials with good thermal performance and strength.

[0037] like Figure 1 and Figure 2 As shown, displacement sensors 22 are also provided at the upper cylinder 14 and the lower cylinder 15, and the displacement sensors 22 are used to detect and control the movement distance of the piston rods of the upper cylinder 14 and the lower cylinder 15. In specific implementation, the piston rods at the upper cylinder 14 and the lower cylinder 15 can control the cutting distance of the blade 121, thereby making the cutting more accurate and reducing the damage caused by the interference of the blades 121.

[0038] like Figure 1 and Figure 2 As shown, the tool holder 1 is also provided with an upper cutting cylinder 141, and the piston rod of the upper cutting cylinder 141 is integrally fixedly connected with the upper cylinder 14. In specific implementation, the upper parts of the guide rods 16 on both sides of the upper cylinder 14 are provided with mounting plates, and the upper cutting cylinder 141 is arranged on the mounting plates. The piston rod of the upper cutting cylinder 141 can push the upper cylinder 14 to move toward the lower cylinder 15. When cutting the copper rod, the upper cutting cylinder 141 needs to be used to push the upper cylinder 14 as a whole to drive the upper knife seat 12 to move, clamp the copper rod first, and then the upper cylinder 14 cooperates with the lower cylinder 15 to cut the copper rod.

[0039] Working principle: When feeding, the copper rod is first abutted by the limit rod 212, and the copper rod is moved a set distance and stopped under the movement of the slide cylinder 21. At this time, under the drive of the upper cutting cylinder, the blade 121 clamps the copper rod, and then driven by the upper oil cylinder 14 and the lower oil cylinder 15, the copper rod is cut into a copper rod of the required size. During actual cutting, a corresponding receiving basket will be set to receive the copper rod.

[0040] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
