[0002] In recent years, with the development of the conductor industry, in order to maximize cost savings, the requirements for subsequent conductor cutting work have become more stringent. However, since conductors are mostly stored by winding them into coils, if the conductor is not straightened, the cutting accuracy of the conductor often cannot meet the required standards.

[0003] Furthermore, when conducting meter weight testing in conductor workshops, conductors are typically cut by hand with scissors or band saws, resulting in uneven cut ends, inaccurate cut lengths, and the weight per unit length can only be obtained through calculation and conversion, further complicating operations.

[0028] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0029] Reference Figures 1 to 4 As shown, a conductor meter-weight cutting device includes a mounting bracket 1, a driving device 2, a template 3, a manual tensioning device 4, and a cutting part 5. The driving device 2 is located above the mounting bracket 1 and consists of cylinders respectively located on both sides of the movable plate 7. The output end of the driving device 2 is downward, which can drive the upper template 31 to move up and down reciprocally, forming a mold with the lower template 32. After the mold is closed, the conductor can be straightened and fixed.

[0030] In one embodiment of the present invention, the template part 3 is disposed between the driving device 2 and the mounting bracket 1. The template part 3 includes an upper template 31 and a lower template 32, wherein the upper template 31 and the lower template 32 are correspondingly disposed. The upper template 31 is connected to the output end of the driving device 2. The driving device 2 can drive the upper template 31 to move up and down reciprocally, thereby forming a mold with the lower template 32.

[0031] In one embodiment of the present invention, the upper end face of the mounting bracket 1 is provided with a fixing plate 6, and the lower mold 32 is installed on the fixing plate 6, thereby realizing the fixed connection between the mounting bracket 1 and the lower mold 32. The output end of the driving device 2 is provided with a movable plate 7, and the upper mold 31 is installed on the lower end face of the movable plate 7. The upper end face of the lower mold 32 is provided with three first grooves 321 of different specifications along the length direction of the mounting bracket 1, which can cover conductors with wire diameters from 4mm to 30mm. The lower end face of the upper mold 31 is also provided with three second grooves. The first grooves 321 and the second grooves are staggered, thereby ensuring that the upper mold 31 and the lower mold 32 form a mold under the action of the driving device 2, which straightens and fixes the conductor. The upper mold 31 and the lower mold 32 are 1 meter long. Based on this, after the conductor is straightened and fixed by the upper mold 31 and the lower mold 32, the conductor is cut from both ends of the mold using a band saw 51. The end face cut is neat and the cutting length is accurate.

[0032] In one embodiment of the present invention, both the first groove 321 and the second groove are V-shaped grooves, and a plurality of first guide pins 322 are provided on the upper end face of the lower mold 32, which are arranged in pairs. A plurality of second guide pins 311 are provided on the lower end face of the upper mold 31. The first guide pins 322 are respectively arranged on both sides of the first groove 321, and the second guide pins 311 are respectively arranged on both sides of the second groove. This arrangement can prevent the conductor from moving inside the mold.

[0033] In one embodiment of the present invention, the manual tensioning device 4 is respectively disposed on both sides of the mounting bracket 1. The manual tensioning device 4 includes a hand crank shaft 41, a guide wheel 42, and a support frame 45 disposed perpendicular to the upper end face of the mounting bracket 1. Each support frame 45 is provided with a locking nut on its outer side to lock the hand crank shaft 41. A gap is provided between the support frames 45 for mounting the guide wheel 42 and winding the conductor. A crank handle 43 is provided at one end of the hand crank shaft 41, and a through hole 44 for the conductor to pass through is provided at the other end of the hand crank shaft 41. The guide wheel 42 is disposed below the through hole 44. The conductor with a diameter of φ4mm or less can be straightened by manually rotating the crank handle 43, and then the conductor can be cut by the band saw 51.

[0034] This conductor meter-weight cutting device is designed for conductors with a diameter of less than 4mm. The conductor is passed through a through-hole 44, and then straightened using a crank handle 43 and guide wheel 42. A band saw 51 is then used to cut the conductor. For conductors with a diameter between 4mm and 30mm, a first groove 321 is provided on the upper end face of the lower mold 32, and a second groove is provided on the lower end face of the upper mold 31. A drive device 2 drives the upper mold 31 to reciprocate up and down, forming a mold with the lower mold 32. After mold closing, the conductor is straightened and fixed. A band saw 51, perpendicular to the upper end face of the mounting bracket 1, is then used to cut the conductor. Therefore, this conductor meter-weight cutting device can quickly and conveniently cut soft and hard conductors from φ1mm to φ30mm to a fixed length with a cutting accuracy within 0.02%, fully meeting workshop requirements.

[0035] In one embodiment of the present invention, the cutting part 5 is respectively disposed between the manual tensioning device 4 and the template part 3. The outer side of the cutting part 5 is provided with a protective cover to prevent the mold from pressing on the hands when the mold is closed. The cutting part 5 includes a band saw 51 and a connecting seat 52 for mounting the band saw 51 to fix the band saw 51. The band saw 51 is set perpendicular to the upper end surface of the mounting bracket 1. The band saw 51 and the connecting seat 52 are rotatably connected. The mounting bracket 1 and the connecting seat 52 are provided with slide rails at corresponding positions. The slide rails are set along the length of the mounting bracket 1, so that different conductor lengths can be cut by sliding the cutting part 5. Guide wheels are provided to achieve precise positioning and cutting of the band saw 51.

[0036] In one embodiment of the present invention, the lower end face of the mounting bracket 1 is provided with four legs 11, and a reinforcing rod 12 is provided between each leg 11. The reinforcing rod 12 is respectively set perpendicular to the leg 11, thereby improving the stability of the conductor meter cutting device.
