Description

Technical Field

[0001] This invention relates to the field of cutting machine tool technology, and in particular to a cutting machine tool for processing metal wire. Background Technology

[0002] In the field of metal wire processing, the initial form of metal wire is mostly long strips of raw material in coils or fixed lengths. Downstream applications such as machinery manufacturing, electronic components, automotive parts, and hardware tools have specific and diverse requirements for the length and size of metal wire. For example, wire segments for making bolts, metal leads for electronic connectors, and wire blanks before spring processing need to be cut from the original long strips of hard metal wire into short segments that meet the specifications of subsequent processes or products to facilitate subsequent processing and use.

[0003] Existing metal wire cutting machines lack a coordinated stop function for cutting and conveying. Specifically, while the machine is cutting, the wire conveying system continues to transport the wire, but the upper and lower cutting tools remain in a fixed position. This fixed position physically obstructs the wire being transported. To avoid this obstruction and continue conveying the wire, the wire and conveyor rollers experience severe friction and slippage due to force imbalance. Over time, this not only causes wear and scratches on the wire surface but also wears down the texture of the conveyor rollers, reducing conveying accuracy. In severe cases, it can even lead to wire deformation or conveyor roller failure, affecting overall processing efficiency and product quality. This results in poor stability and limited practicality. Summary of the Invention

[0004] This invention relates to a cutting machine tool for metal wire processing, comprising a conveying assembly and a cutting assembly. The conveying assembly enables the conveying of metal wire, and the cutting assembly enables the cutting operation of the metal wire. Furthermore, the cutting assembly has a follow-up movement function during the cutting action, meaning it can move along with the conveying of the metal wire while maintaining the cutting position. This avoids wire wear, scratches, and damage to the conveying rollers, resulting in stable and precise processing with high stability and practicality.

[0005] This invention provides a cutting machine tool for metal wire processing, specifically including: a conveying assembly, which includes a conveying seat, a driving wheel, a driven wheel, and a cutting push rod.

The follower mechanism includes a follower seat and a control shaft. The follower seat is inserted into the side of the conveyor seat, and the control shaft is rotatably connected to the top of the conveyor seat. The synchronization mechanism includes a pressing synchronization seat, an actuating gear, and a buffer shaft.

The cutting seat is inserted into the inside of the follower seat, and the cutting gear is rotatably connected to the inside of the follower seat. The lower cutter is fixedly installed inside the follower seat, and an upper cutter is fixedly installed at the bottom of the cutting seat. The height of the upper cutter is higher than the height of the pressing synchronization seat.

[0006] Furthermore, the conveying assembly also includes a length measuring sensor, which is fixedly installed on the top of the conveying seat. The conveying seat and the follower seat have a conveying channel inside. The metal wire is conveyed inside the conveying channel of the conveying seat through friction with the driving wheel and the driven wheel, and finally enters the conveying channel of the follower seat. The length measuring sensor can monitor the conveying length of the metal wire in the conveying channel, and the lower cutter is located at the bottom of the conveying channel.

[0007] Furthermore, the bottom of the cutting push rod is provided with a drive rack, and the side of the control shaft is provided with a drive gear, and the drive rack and the drive gear mesh with each other for transmission.

[0008] Furthermore, the cross-sectional shape of the control shaft side is a regular polygon, and the buffer shaft and the cutting gear are both provided with drive grooves. The part of the control shaft with the regular polygon cross-section is inserted into the drive groove of the buffer shaft and the cutting gear, and the control shaft passes through the interior of the follower seat.

[0009] Furthermore, the buffer shaft has a spiral-shaped buffer pressure groove on its exterior, and the actuating gear has a linkage protrusion inside, which is inserted into the buffer pressure groove.

[0010] Furthermore, the side of the buffer shaft is provided with a buffer pressure spring, and the two ends of the buffer pressure spring abut against the side of the buffer shaft and the inside of the follower seat, respectively.

[0011] Furthermore, the side of the clamping synchronizing seat is provided with a clamping rack, and the clamping rack and the actuating gear mesh and drive each other.

[0012] Furthermore, the side of the cutting seat is provided with a cutting rack, and the cutting rack and the cutting gear mesh with each other for transmission.

[0013] Furthermore, the side of the follower seat is provided with a reset spring, and the two ends of the reset spring are respectively fixedly connected to the side of the follower seat and the inside of the conveyor seat.

[0014] This invention provides a cutting machine tool for processing metal wire, which has the following advantages: The conveying component enables the transport of metal wire, while the cutting component enables the cutting of the metal wire. Furthermore, the cutting component has a follow-up movement function during the cutting action, meaning it moves along with the transported metal wire. This ensures the cutting position remains unchanged without obstructing the transport of the metal wire, preventing wire wear, scratches, and damage to the conveyor rollers. The process is stable and precise, improving the stability and practicality of the device. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please refer to Figures 1 to 9 Example 1: This invention proposes a cutting machine tool for metal wire processing, comprising: a conveying assembly 1, which includes a conveying seat 101, a driving wheel 102, a driven wheel 103, and a cutting push rod 104. The driving wheel 102 and the driven wheel 103 are rotatably connected inside the conveying seat 101, and the driving wheel 102 is driven by a drive motor. The cutting push rod 104 is fixedly installed on the top of the conveying seat 101. The invention also includes a cutting assembly, which consists of a follower mechanism 2, a synchronization mechanism 3, and a cutting mechanism 4. The follower mechanism 2 includes a follower seat 201 and a control shaft 202. The follower seat 201 is inserted into the side of the conveyor seat 101, and the control shaft 202 is rotatably connected to the top of the conveyor seat 101. The synchronization mechanism 3 includes a pressing synchronization seat 301, an action gear 302, and a buffer shaft 303. The pressing synchronization seat 301 is inserted into the inside of the follower seat 201, and the action gear 302 is rotatably connected to the side of the follower seat 201. The buffer shaft 303 is inserted into the inside of the follower seat 201. The cutting mechanism 4 includes a cutting seat 401, a cutting gear 402, and a lower cutter 403. The cutting seat 401 is inserted into the inside of the follower seat 201, and the cutting gear 402 is rotatably connected to the inside of the follower seat 201. The lower cutter 403 is fixedly installed inside the follower seat 201, and an upper cutter 4012 is fixedly installed at the bottom of the cutting seat 401. The height of the upper cutter 4012 is higher than the height of the pressing synchronization seat 301.

[0029] The conveying assembly 1 also includes a length measuring sensor 105, which is fixedly installed on the top of the conveying base 101. The conveying base 101 and the follower base 201 have a conveying channel 1011 inside. The metal wire is conveyed within the conveying channel 1011 of the conveying base 101 through friction with the driving wheel 102 and the driven wheel 103, and finally enters the conveying channel 1011 of the follower base 201. The length measuring sensor 105 can monitor the conveying length of the metal wire in the conveying channel 1011. The lower cutter 403 is located at the bottom of the conveying channel 1011. In use, the metal wire can be conveyed through the conveying assembly 1, thus facilitating subsequent cutting operations. In this system, the drive wheel 102 rotates under the drive of the drive motor. When the metal wire is inserted into the conveying channel 1011 of the conveying seat 101, the metal wire is conveyed through friction and compression between the drive wheel 102, the driven wheel 103, and the metal wire. This makes the operation convenient and flexible. At this time, the clamping synchronizing seat 301 and the cutting seat 401 will not intrude into the conveying channel 1011 inside the follower seat 201, ensuring stable conveying of the metal wire. The length measuring sensor 105 can monitor the conveying length of the metal wire. When the cutting length is reached, the metal wire can be cut by the cutting component, realizing a cyclic cutting operation of the metal wire with high cutting efficiency.

[0030] The cutting push rod 104 has a drive rack 1041 at its bottom, and a drive gear 2021 is provided on the side of the control shaft 202. The drive rack 1041 and the drive gear 2021 mesh and transmit power. During use, the cutting assembly can move along with the metal wire during the cutting action. While ensuring that the cutting position remains unchanged, it will not hinder the conveying action of the conveying assembly 1 on the metal wire. It is stable in use. After the metal wire reaches the cutting length during conveying, the cutting push rod 104 extends to provide driving force for the subsequent action of the cutting assembly. The cross-sectional shape of the shaft on the side of the control shaft 202 is a regular polygon, and both the buffer shaft 303 and the cutting gear 402 have drive grooves 402 inside. 1. The control shaft 202, with its regular polygonal cross-section, is inserted into the drive groove 4021 of the buffer shaft 303 and the cutting gear 402. The shaft of the control shaft 202 passes through the interior of the follower seat 201. When the cutting push rod 104 extends, the drive rack 1041 can drive the control shaft 202 to rotate through the drive gear 2021. When the control shaft 202 rotates, it can drive the synchronization mechanism 3 to trigger the clamping synchronization function and the cutting mechanism 4 to cut the metal wire. The clamping synchronization function of the synchronization mechanism 3 will be triggered before the cutting action of the cutting mechanism 4, ensuring that the action of the cutting component moving with the metal wire is triggered first, avoiding damage or excessive wear to the wire or the conveying component 1, and ensuring stable use.

[0031] The buffer shaft 303 has a spiral-shaped buffer pressure groove 3031 on its exterior, and the actuating gear 302 has a linkage protrusion 3021 inside, which is inserted into the buffer pressure groove 3031. A buffer pressure spring 3032 is provided on the side of the buffer shaft 303, with its two ends abutting against the side of the buffer shaft 303 and the interior of the follower seat 201, respectively. In use, when the control shaft 202 rotates, it can drive the buffer shaft 303 and the cutting gear 402 to rotate synchronously via the drive groove 4021. Under the action of the buffer pressure spring 3032, the buffer shaft 303 and the actuating gear 302 maintain a unified state, so that the actuating gear 302 will rotate synchronously when the buffer shaft 303 rotates. A clamping rack 3011 is provided on the side of the clamping synchronizing seat 301, and the clamping rack 3011 and the actuating gear 302 mesh and transmit power. The actuating gear 302 rotates... When in motion, the clamping rack 3011 drives the clamping synchronizing seat 301 to move down synchronously until the clamping synchronizing seat 301 abuts against the top of the metal wire. At this point, the clamping synchronizing seat 301 is blocked by the top of the metal wire and cannot move down, so the actuating gear 302 cannot rotate. Afterwards, when the control shaft 202 continues to rotate, the buffer pressure groove 3031 can drive the buffer shaft 303 to move to one side under the guidance of the linkage protrusion 3021 and compress the buffer pressure top spring 3032, thereby continuously increasing the contact and squeezing pressure between the clamping synchronizing seat 301 and the metal wire, that is, the friction between the clamping synchronizing seat 301 and the metal wire. Afterwards, the follower seat 201 can move synchronously with the conveying of the metal wire under the action of the friction between the clamping synchronizing seat 301 and the metal wire and stretch the return spring 2011, thereby triggering the action of the cutting component moving with the conveying of the metal wire before the cutting action, which is convenient and flexible to use.

[0032] The cutting seat 401 has a cutting rack 4011 on its side, and the cutting rack 4011 and the cutting gear 402 mesh with each other. In use, when the cutting gear 402 rotates, it can drive the cutting seat 401 and the upper cutter 4012 to move downward through the cutting rack 4011. Since the setting height of the upper cutter 4012 is higher than the setting height of the clamping synchronizing seat 301, the upper cutter 4012 will only contact the metal wire to perform the cutting action after the cutting assembly moves with the conveying of the metal wire. When the upper cutter 4012 moves downward, it can cooperate with the lower cutter 403 to achieve the cutting action of the metal wire inside the conveying channel 1011. The cut metal wire can fall from the side of the follower seat 201 for collection, so as to be used for subsequent processing. It is convenient to operate and flexible to use.

[0033] The follower seat 201 has a reset spring 2011 on its side, and the two ends of the reset spring 2011 are fixedly connected to the side of the follower seat 201 and the inside of the conveyor seat 101, respectively. In use, after a single cut is completed, the cutting push rod 104 retracts to drive the synchronization mechanism 3 and the cutting mechanism 4 to reset. After the synchronization mechanism 3 and the cutting mechanism 4 are reset, the follower seat 201 will also automatically reset under the action of the reset spring 2011, in preparation for the next cut.

[0034] The specific usage and function of this embodiment: In this invention, the metal wire can be conveyed through the conveying assembly 1, thereby facilitating subsequent cutting operations. The drive wheel 102 can rotate under the drive of the drive motor. Thus, when the metal wire is inserted into the conveying channel 1011 of the conveying seat 101, the metal wire can be conveyed under the action of friction and compression between the drive wheel 102, the driven wheel 103 and the metal wire. The operation is convenient and flexible. At this time, neither the pressing synchronization seat 301 nor the cutting seat 401 will invade the conveying channel 1011 inside the follower seat 201, ensuring stable conveying of the metal wire. The length measuring sensor 105 can monitor the conveying length of the metal wire, so that when the cutting length is reached, the metal wire can be conveyed through the conveying assembly 1011. The cutting assembly can cut metal wire, realizing a cyclic cutting operation. During the cutting action, the cutting assembly can move along with the metal wire conveyor, ensuring that the cutting position remains unchanged and does not hinder the conveying action of the conveying assembly 1. It is stable in use. After the metal wire reaches the cutting length during conveying, the cutting push rod 104 extends to provide driving force for the subsequent action of the cutting assembly. When the cutting push rod 104 extends, the drive rack 1041 can drive the control shaft 202 to rotate through the drive gear 2021. When the control shaft 202 rotates, it can drive the synchronization mechanism 3 to trigger the clamping synchronization function and the cutting action of the cutting mechanism 4 on the metal wire. The clamping synchronization of the synchronization mechanism 3... The function is triggered before the cutting action of the cutting mechanism 4, ensuring that the action of the cutting component moving with the metal wire is triggered first, avoiding damage or excessive wear to the wire or the conveying component 1. When the control shaft 202 rotates, it can drive the buffer shaft 303 and the cutting gear 402 to rotate synchronously through the drive groove 4021. Under the action of the buffer pressure spring 3032, the buffer shaft 303 and the action gear 302 maintain a whole state. Thus, when the buffer shaft 303 rotates, the action gear 302 will rotate synchronously. When the action gear 302 rotates, it can drive the clamping synchronization seat 301 to move synchronously downward through the clamping rack 3011 until the clamping synchronization seat 301 abuts against the top of the metal wire. At this time, due to the clamping synchronization seat 301 is blocked by the top of the metal wire and cannot move downwards, thus preventing the actuating gear 302 from rotating. Subsequently, as the control shaft 202 continues to rotate, the buffer pressure groove 3031, guided by the linkage protrusion 3021, drives the buffer shaft 303 to move to one side and compresses the buffer pressure top spring 3032. This continuously increases the contact and compression pressure between the pressing synchronization seat 301 and the metal wire, i.e., the frictional force between the pressing synchronization seat 301 and the metal wire. Then, under the action of the frictional force between the pressing synchronization seat 301 and the metal wire, the follower seat 201 moves synchronously with the conveying of the metal wire and stretches the return spring 2011, thereby triggering the movement of the cutting assembly following the conveying of the metal wire before the cutting action.When the cutting gear 402 rotates, it drives the cutting seat 401 and the upper cutter 4012 to move downwards via the cutting rack 4011. Since the upper cutter 4012 is positioned higher than the clamping synchronizing seat 301, it only contacts the metal wire and performs the cutting action after the cutting assembly is triggered to move along with the conveying of the metal wire. As the upper cutter 4012 moves downwards, it cooperates with the lower cutter 403 to cut the metal wire inside the conveying channel 1011. The cut metal wire falls from the side of the follower seat 201 and is collected for subsequent processing. After a single cut, the cutting push rod 104 retracts, resetting the synchronizing mechanism 3 and the cutting mechanism 4. Once the synchronizing mechanism 3 and the cutting mechanism 4 have reset, the follower seat 201 automatically resets under the action of the reset spring 2011, ready for the next cut.
