Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a metal wire cold cutting mechanism. Background Technology

[0002] Metal wire is a linear product made of metal materials. It has good ductility, conductivity and strength. It is processed by rolling and drawing processes. The diameter range includes extremely fine wires to thicker bars. Metal wire has a wide range of applications in aerospace, electronics and electrical, machinery manufacturing and building decoration. For example, it is used to make cable conductors, springs, fasteners, steel bars and various precision parts. It is an indispensable basic material in modern industrial production and daily life.

[0003] When cutting wire, the cold cutting mechanism uses hydraulic or pneumatic power to push the die. The wire breaks at the stress concentration point through the extrusion of the upper and lower dies. The die is a concave groove. During extrusion, the wire is locally deformed until it breaks. However, when cutting large-diameter wire, the hydraulic system needs to provide high pressure. Long-term operation leads to aging of the cylinder seals and air leakage of pneumatic components. Existing technology uses two sets of high-speed rotating circular blades to work together. The wire is cut when it passes through the gap between the blades. The cutting speed is fast, but the blades are constantly subjected to high-frequency impact during high-speed cutting, resulting in a short service life and the need for frequent replacement of new blades. This reduces cutting efficiency and increases the cost of cutting operations. Utility Model Content

A whetstone is mounted on the top of the outer side of the fixed frame. The bottom of the outer wall of the whetstone is slidably connected to the inside of the top of the fixed frame. A spring is fixedly connected to the right side of the outer wall of the whetstone. The other end of the outer wall of the spring is fixedly connected to the outer wall of the fixed frame. A power assembly is mounted on the right side of the outer side of the support plate.

[0010] As a further description of the above technical solution:

With the help of motor power, the blade of the knife is sharpened as needed, avoiding the need to stop and change the knife due to blade wear, and solving the problem of reduced cutting efficiency.

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 6 This utility model provides an embodiment of a metal wire cold cutting mechanism, including a machine tool 1. A cutting mechanism 2 is installed on the top right end of the outer wall of the machine tool 1. The cutting mechanism 2 is used to cut metal wire. A grinding mechanism 3 is installed on the outer side of the machine tool 1. The grinding mechanism 3 is used to grind the cutting edge. The cutting mechanism 2 includes a protective cover 201, which is installed on the top right end of the outer wall of the machine tool 1. A slide 202 is installed inside the protective cover 201. A cutting tool 203 is fixedly connected to the bottom right end of the outer wall of the slide 202. A drive assembly 204 is installed at the outer rear end of the protective cover 201. The drive assembly 204 includes a motor 2041, which is installed at the outer rear end of the protective cover 201. The output end of motor 2041 is fixedly connected to drive shaft 2042. The outer wall of drive shaft 2042 is rotatably connected to the front and rear ends of protective cover 201. A rotating frame 2043 is fixedly connected to the middle of drive shaft 2042. The top of the outer wall of rotating frame 2043 is slidably connected to the inside of slide 202. A cable outlet frame 2044 is fixedly connected to the bottom right side of protective cover 201. A support frame 2045 is fixedly connected to the bottom of outer wall of motor 2041. The bottom of outer wall of support frame 2045 is fixedly connected to the top of outer wall of machine tool 1. A limit frame 2046 is fixedly connected to the middle of right end of protective cover 201. The inside of limit frame 2046 is slidably connected to the outer wall of tool 203.

[0034] Specifically, in the transmission structure of the metal wire cutting equipment, the output end of the motor 2041 is tightly connected to the transmission shaft 2042 by welding. The support frame 2045 welded to the bottom of the motor 2041 is firmly fixed to the top of the machine tool 1, providing a reliable support foundation for the operation of the motor 2041, ensuring its stability during operation and avoiding displacement or shaking caused by vibration. When the motor 2041 is started, the output power is transmitted through the transmission shaft 2042 to the rotating frame 2043 welded in the middle. The top of the rotating frame 2043 is restricted inside the slide 202, and the two form a sliding fit relationship. Therefore, as the motor 2041 is started, the output power is transmitted to the rotating frame 2043 welded in the middle via the transmission shaft 2042. The top of the rotating frame 2043 is restricted inside the slide 202, and the two form a sliding fit relationship. The rotation of the rotating frame 2043 causes the slide 202 to move, which in turn causes the tool 203 connected to the slide 202 to move accordingly. At the same time, the internal space of the limiting frame 2046 constrains the tool 203, restricting its movement to the vertical direction only. Through this structural design, the tool 203 can continuously cut metal wire, solving the problem that although the cutting speed is fast when using two sets of high-speed rotating circular blades, the blades are constantly subjected to high-frequency impacts during high-speed cutting, which greatly shortens their service life, requires frequent replacement of cutting blades, reduces cutting efficiency, and significantly increases the cost of cutting operations.

[0035] Reference Figure 4 , Figure 5 and Figure 7 The grinding mechanism 3 includes a support plate 301, which is mounted on the outside of the machine tool 1. A fixed frame 302 is slidably connected to the top of the outer wall of the support plate 301. A whetstone 303 is mounted on the top of the outer side of the fixed frame 302. The bottom end of the outer wall of the whetstone 303 is slidably connected to the inside of the top end of the fixed frame 302. A spring 304 is fixedly connected to the right side of the outer wall of the whetstone 303. The other end of the outer wall of the spring 304 is fixedly connected to the outer wall of the fixed frame 302. A power assembly 305 is mounted on the outer right end of the support plate 301. The power assembly 305 includes a second transmission shaft 3051, which is mounted on the outer right end of the support plate 301. A triangular knob 3052 is fixedly connected to the top of the outer wall of the second drive shaft 3051. A gear 3053 is fixedly connected to the middle of the triangular knob 3052. A rack 3054 is installed on the front side of the outer wall of the gear 3053. The front side of the outer wall of the rack 3054 is fixedly connected to the rear side of the outer wall of the fixed frame 302. The outer wall of the gear 3053 and the rear side of the outer wall of the rack 3054 are meshed. A ratchet 3055 is fixedly connected to the bottom of the outer wall of the second drive shaft 3051. A pawl 3056 is installed on the outside of the ratchet 3055. A rotating shaft 3057 is rotatably connected inside the pawl 3056. The bottom end of the rotating shaft 3057 is fixedly connected to the top of the bracket 3058.

[0036] Specifically, in the grinding mechanism 3, a spring 304 is welded to the rear side of the whetstone 303. The rear end of the spring 304 is fixed to the outside of the fixing frame 302. The rear side of the fixing frame 302 is welded to the rack 3054. When the triangular knob 3052 is rotated, the power is transmitted to the gear 3053 through the transmission shaft 3051, causing the rack 3054 meshing with the gear 3053 to move, thereby adjusting the whetstone 303 to the required position. The ratchet 3055 welded to the bottom of the transmission shaft 3051 and its outer pawl 3056 can grind the whetstone. The whetstone 303 is fixed in position, and its bottom can slide in the top space of the fixed frame 302. When the cutter 203 is cutting, the whetstone 303 can be moved to the movement path of the cutter 203. When the whetstone 303 is squeezed to the right by the cutter 203, the spring 304 moves it to the left with its elasticity, realizing the left and right reciprocating motion. With the power of the motor 2041, the cutter 203 can be sharpened as needed, solving the problem that the cutter 203 needs to be replaced after long-term use and wear, which reduces the cutting efficiency of the cutting machine.

[0037] Reference Figure 2 , Figure 3 and Figure 7 A bracket 3058 is fixedly connected to the bottom of the outer wall of the second drive shaft 3051. The top of the outer wall of the bracket 3058 is slidably connected to the bottom of the outer wall of the fixed frame 302, which can provide stable support for the grinding mechanism 3.

[0038] Specifically, a bracket 3058 is fixedly connected to the bottom of the outer wall of the second drive shaft 3051. The top of the outer wall of the bracket 3058 and the bottom of the outer wall of the fixed frame 302 form a sliding connection structure. This structure can provide stable support for the grinding mechanism 3 when the second drive shaft 3051 is running. The sliding connection design allows the bracket 3058 to move smoothly along the bottom of the fixed frame 302, ensuring that the grinding mechanism 3 remains stable in different working positions and avoiding grinding accuracy deviations caused by unstable support.

[0039] Working principle: By activating motor 2041, the cutter 203 moves vertically, achieving continuous cutting of metal wire. Because a drive shaft 2042 is welded to the output end of motor 2041, and a support frame 2045 welded to the bottom of motor 2041 is fixed to the top of machine tool 1, it provides stable support for the operation of motor 2041. When motor 2041 is activated, its power is transmitted through drive shaft 2042 to the rotating frame 2043 welded in its middle. Because the top of the rotating frame 2043 is confined inside the slide 202, it can slide... Therefore, when the rotating frame 2043 rotates, it can drive the slide 202 to move, which in turn drives the cutter 203 to move. Due to the restriction of the internal space of the limiting frame 2046 on the cutter 203, the cutter 203 can only move vertically, thereby realizing continuous cutting of metal wire. This solves the problem of using two sets of high-speed rotating circular blades to cooperate with each other. When the wire passes through the gap between the blades, it is cut off. The cutting speed is fast, but the blade will be subjected to high-frequency impact during high-speed cutting. It is necessary to frequently replace the new cutting blade, which reduces the cutting efficiency and increases the cost of cutting operations.

[0040] By rotating the triangular knob 3052, the whetstone 303 is moved to the desired position, thus sharpening the blade of the knife 203. A spring 304 is welded to the rear of the whetstone 303, and the rear end of the spring 304 is fixed to the outside of the fixing bracket 302. The rear of the fixing bracket 302 is welded to the rack 3054. When the triangular knob 3052 is rotated, its power is transmitted through the transmission shaft 3051 to the gear 3053, causing the rack 3054, which meshes tightly with the gear 3053, to move, thereby moving the whetstone 303 to the desired position. The sharpening is achieved through the ratchet 3055 welded to the bottom of the transmission shaft 3051 and the pawl 3056 mounted on its outer side. The whetstone 303 is fixed in position, and its bottom can slide within the top space of the fixed frame 302. When the blade 203 is cutting, the whetstone 303 can be moved to the path of the blade 203. When the whetstone 303 is pressed to the right by the blade 203, the spring 304 can use its elasticity to move the whetstone 303 to the left, realizing the reciprocating motion of the whetstone 303. With the power generated by the motor 2041, the blade 203 can be sharpened as needed, solving the problem that the blade 203 is worn after long-term use, requiring the machine to be stopped and the blade 203 replaced, thus reducing the cutting efficiency of the cutting machine.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
