Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, and specifically discloses a wire cutting machine that can adjust the cutting length. Background Technology

[0002] In the production and processing of industries such as wire and cable, and electronics, wire cutting machines are the core equipment for precisely cutting coiled wires into segments of specific lengths. Their cutting precision and adaptability to different wire specifications act like the first domino, directly influencing the efficiency of downstream assembly processes and product quality.

[0003] Existing wire cutting machines are relatively simple in function, only capable of cutting wires and cables to the same length, and lack a mechanism for flexibly adjusting the cutting length. This makes them completely incapable of handling diverse production orders requiring wires of different lengths and specifications, severely limiting production flexibility and adaptability. Even those machines with length adjustment functions mostly rely on manual operation. Operators need to rely on experience to repeatedly adjust the limit device, and after each adjustment, a test cut must be performed, followed by careful measurement of the cut wire length. If the length does not meet requirements, the limit device must be adjusted again, and this process is repeated endlessly. This method is not only time-consuming and labor-intensive, but also severely impacts production efficiency. Therefore, a wire cutting machine with adjustable cutting length is needed to solve these problems. Utility Model Content

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4A wire cutting machine with adjustable cutting length includes a base 1 and a cutting mechanism, wherein the front end of the base 1 is provided with a length adjustment mechanism. The length adjustment mechanism includes a mounting plate 2. A scale plate 3 is fixedly connected to the front end of the mounting plate 2. Two first fixed plates 20 and two second fixed plates 21 are fixedly connected to the front end of the mounting plate 2. A first lead screw 4 is rotatably connected between the two first fixed plates 20. A second lead screw 5 is rotatably connected between the two second fixed plates 21. A first slider 6 is threaded to the outer wall of the first lead screw 4. A second slider 7 is threaded to the outer wall of the second lead screw 5. A first pressure sensor 24 is installed at the right end of the first slider 6. Two end plates 8 are fixedly connected to the front end of the second slider 7. A first electric push rod 9 is installed on the opposite side of each of the two end plates 8. The two first electric push rods 9 pass through the two end plates 8 and are fixedly connected to a clamping plate 10. A second pressure sensor 22 is installed on the outer wall of the first fixed plate 20 and the second fixed plate 21 at the right end. A conveying mechanism is provided at the front end of the base 1.

[0020] In this embodiment: Before use, according to the target wire cutting length: rotate the knob of the first lead screw 4, causing the first slider 6 to slide along the mounting plate 2, and fix the position with the scale plate 3 (the first pressure sensor 24 at its right end senses the end of the wire); at the same time, start the second motor 23, drive the second lead screw 5 to rotate, and cause the second slider 7 to slide to abut against the second pressure sensor 22, completing the positioning limit. Then feed the wire: the wire passes through the lead hole of the lead plate 19, the wire tube 15 of the fixing seat 14, and extends between the two clamping plates 10. The controller controls the extension and retraction of the first electric push rod 9, so that the clamping plates 10 clamp the wire. Then, the first motor 18 and the second motor 23 are started simultaneously. The first motor 18 drives the conveying roller 17 to feed the wire, and the second motor 23 drives the second lead screw 5 to rotate, pulling the wire with the clamping plates 10, and coordinating the wire feeding. When the end of the wire touches the first pressure sensor 24, the sensor sends a signal, and the controller controls the extension and retraction of the second electric push rod 12, cutting with the cutting blade 13; after cutting, the first electric push rod 9 retracts to loosen the wire, and the equipment enters the next round. When adjusting the cutting line length, simply adjust the first slider 6 for positioning and the second slider 7 for abutment limit; no disassembly is required.

[0021] As a technical optimization of this utility model, the wire cutting mechanism includes two horizontal plates 11 fixedly connected to the front end of the base 1. Each of the two horizontal plates 11 has a second electric push rod 12 installed on its opposite side. The output ends of the two second electric push rods 12 pass through the horizontal plates 11 and are fixedly connected to a cutting tool 13.

[0022] In this embodiment, two second electric actuators 12 can drive two cutting blades 13 to move relative to each other.

[0023] As a technical optimization of this utility model, the conveying mechanism includes an auxiliary plate 16 fixedly connected to the front end of the base 1. Two first motors 18 are installed at the front end of the auxiliary plate 16. The output ends of the two first motors 18 pass through the auxiliary plate 16 and are fixedly connected to conveying rollers 17. A fixed seat 14 is fixedly connected to the front end of the base 1. Multiple threading tubes 15 are fixedly connected through the outer wall of the fixed seat 14.

[0024] In this embodiment, two first motors 18 can drive two conveying rollers 17 to rotate in opposite directions to convey the cable.

[0025] As a technical optimization of this utility model, a knob fixedly connected to the first lead screw 4 is installed on the outer wall of the first fixing plate 20 at the left end, and a second motor 23 with its output end fixedly connected to the second lead screw 5 is installed on the outer wall of the second fixing plate 21 at the left end.

[0026] In this embodiment: the first lead screw 4 can be driven to rotate by a knob, and the second lead screw 5 can be driven to rotate by a second motor 23.

[0027] As a technical optimization of this utility model, the rear ends of the first slider 6 and the second slider 7 are both in contact with the front end of the mounting plate 2 and the front end of the scale plate 3.

[0028] In this embodiment, the rear ends of the first slider 6 and the second slider 7 are both in contact with the front end of the mounting plate 2 and the front end of the scale plate 3, which can prevent the first slider 6 and the second slider 7 from rotating axially.

[0029] As a technical optimization of this utility model, the front end of the substrate 1 is provided with a lead plate 19 with lead holes.

[0030] In this embodiment, the cable can be easily guided by the lead plate 19.

[0031] As a technical optimization of this utility model, the outer wall of the mounting plate 2 is fixedly connected to two mounting seats, and both mounting seats are detachably connected to the base 1 by bolts.

[0032] In this embodiment, both mounting bases are detachably connected to the base 1 by bolts, which allows for easy removal of the mounting plate 2, thus facilitating future maintenance and replacement.

[0033] As a technical optimization of this utility model, a controller and an operation panel are installed on the outer wall of the base 1.

[0034] In this embodiment: the controller can receive signals from the first pressure sensor 24 and the second pressure sensor 22, and synchronously link the start and stop of the first motor 18, the second motor 23, the first electric actuator 9, and the second electric actuator 12 and their movement rhythm. The operation panel provides an intuitive interactive interface for the operator, who can input the target cutting length and start or pause the equipment through the panel.

[0035] The working principle and usage process of this utility model are as follows: Before use, parameters are set according to the target wire cutting length: Rotate the knob of the first lead screw 4 to drive the first slider 6 to slide along the mounting plate 2, and accurately determine the position of the first slider 6 in conjunction with the scale of the scale plate 3 (the first pressure sensor 24 at its right end is used to sense the end of the wire later); At the same time, start the second motor 23 to drive the second lead screw 5 to rotate, and drive the second slider 7 to slide to abut against the second pressure sensor 22, completing the length positioning and slider limit before cutting. Next, prepare for feeding and conveying: Pass one end of the wire through the lead hole of the lead plate 19 and the wire tube 15 of the fixing seat 14 in sequence until it extends between the two clamping plates 10 at the front end of the second slider 7; The controller first controls the two first electric push rods 9 to extend, pushing the clamping plates 10 to clamp the wire, and then starts the first motor 18 and the second motor 23 simultaneously. The first motor 18 drives the conveying roller 17 to convey the wire forward, and the second motor 23 drives the second lead screw 5 to rotate, driving the clamping plates 10 to pull the wire to the left, forming a coordinated wire feeding mode of conveying and pulling, ensuring that the wire is fed smoothly. When the end of the wire touches the first pressure sensor 24, the sensor immediately sends a signal to the controller. The controller then controls the two second electric push rods 12 to extend, driving the cutting blade 13 to precisely cut the wire. After cutting, the first electric push rod 9 retracts, causing the clamping plate 10 to release the wire, and the equipment automatically enters the next wire feeding and cutting cycle. If the wire length needs to be adjusted, simply repeat the steps of adjusting the positioning of the first slider 6 and the abutment limit of the second slider 7. No parts need to be disassembled, making the operation convenient and accurate.
