Description

Technical Field

[0001] This utility model relates to the field of automated equipment, specifically to a continuous wire cutting machine. Background Technology

[0002] Continuous wire cutting machines have made significant progress and development in recent years. The automation level of continuous wire cutting machines has been continuously improved, and they can realize the automatic completion of the entire process from wire feeding, measurement, cutting to discharge, reducing manual intervention and improving production efficiency. Continuous wire cutting machines can also adapt to the processing needs of wires of different specifications, sizes and types, and have flexible adjustment functions, which can quickly adapt to changes in the production line.

[0003] Chinese patent CN109226593B discloses a wire cutting machine, including a wire cutting mechanism and a wire feeding mechanism. The wire feeding mechanism includes several sets of wire feeding wheels and an encoder assembly for counting the wire feeding length. It also includes a vertical shaping assembly and a horizontal shaping assembly. The vertical shaping assembly includes a vertical fixing plate with multiple vertically arranged vertical adjustment grooves, each connected to a longitudinal shaping wheel. Two adjacent longitudinal shaping wheels are located on opposite sides of the wire feeding track. The horizontal shaping assembly includes a horizontal fixing plate with multiple horizontally arranged horizontal adjustment grooves, each connected to a horizontal shaping wheel. Two adjacent longitudinal shaping wheels are located on opposite sides of the wire feeding track. This invention, by setting up vertical and horizontal shaping assemblies, allows the cable to be shaped in two directions during the feeding process, facilitating subsequent wire cutting. However, this device still has the following problems: 1. After the wire is cut, it falls directly onto the workbench, requiring operators to sort and bundle it, which consumes a lot of manpower and time, reducing processing efficiency.

[0004] 2. When changing the size of the processed wire, the shaping wheels need to be adjusted one by one, which is quite time-consuming.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A continuous wire cutting machine, comprising a base 1;

[0035] An auxiliary wire management mechanism 2 for aligning and fixing the cut wires is installed at the left end of the base 1;

[0036] The auxiliary cable management mechanism 2 includes a drive component 21 and a cable clamping component 22; the drive component 21 and the cable clamping component 22 are connected, and both the drive component 21 and the cable clamping component 22 are connected to the base 1.

[0037] The base 1 is equipped with a V-shaped wheel shaping mechanism 3 for shaping unprocessed wires at its right end;

[0038] The base 1 is equipped with a wire cutting assembly 4 for cutting wires; the wire cutting assembly 4 is located to the right of the auxiliary wire management mechanism 2;

[0039] The base 1 is equipped with a wire cutting positioning tube 6 for positioning the wire to be cut; the wire cutting positioning tube 6 is located on the right side of the wire cutting assembly 4.

[0040] Two sets of feeding rollers 5 for moving the wire are rotatably connected to the base 1; the two sets of feeding rollers 5 are located on the left side of the wire cutting assembly 4 and the right side of the wire cutting positioning tube 6, respectively.

[0041] The operator passes the wire to be cut through the V-shaped wheel shaping mechanism 3, the feeding roller group 5, the wire cutting positioning tube 6, the wire cutting assembly 4, the feeding roller group 5, and the auxiliary wire management mechanism 2 in sequence. Then, the V-shaped wheel shaping mechanism 3 is adjusted to clamp the wire so that it can shape the wire. The device is then started, and the feeding roller group 5 on the right side rolls and squeezes the wire, causing it to move to the left. The wire is squeezed and shaped at the V-shaped wheel shaping mechanism 3 and is no longer bent. Then, it is fed into the wire cutting assembly 4 by the wire cutting positioning tube 6 for cutting. The cut wire moves to the left under the action of the feeding roller group 5 on the left side and enters the auxiliary wire management mechanism 2 for fixing. When there are enough cut wires to bundle, the operator bundles the wires that have been processed and fixed on the left end, and then releases the auxiliary wire management mechanism 2 from the fixing of the cut wires and removes the wires.

[0042] The feeding roller group 5 adopts existing mature methods in the field, such as the wire feeding structure of a wire cutting machine disclosed in Chinese patent CN109226593B.

[0043] The wire cutting component 4 employs existing mature methods in the field, such as the wire cutting device of a wire cutting and stripping machine disclosed in Chinese Patent CN118676715A.

[0044] This invention enables the processed wires to be bundled without manual sorting and alignment, reducing time waste; it also allows for the adjustment of the V-shaped wheel shaping mechanism 3 in one operation.

[0045] The drive assembly 21 includes a cylinder 211, a fixed rod limiting slide groove 212, a fixed rod 213, and a motor 214. The left front sidewall of the base 1 is fixedly connected to the cylinder 211, and the drive end of the cylinder 211 is fixedly connected to the fixed rod 213. The fixed rod limiting slide groove 212 is provided on the left front side of the base 1 and is located to the right of the cylinder 211. The fixed rod 213 is slidably connected to the base 1 through the fixed rod limiting slide groove 212. The fixed rod 213 is connected to the wire clamping assembly 22, and the drive end of the motor 214 is connected to the wire clamping assembly 22. The motor 214 is fixedly connected to the base 1 at the right end of the wire clamping assembly 22. The motor 214 is a geared servo motor.

[0046] The wire clamping assembly 22 includes a rotating disk 221, wire holes 222, limiting holes 223, and a wire clamping disc 224. The right end of the rotating disk 221 is fixedly connected to the drive end of the motor 214. The rotating disk 221 has multiple wire holes 222 arranged in a circular array. The center of the rotating disk 221 has a limiting hole 223 for limiting the wire clamping disc 224. The wire clamping disc 224 is slidably connected to the rotating disk 221 through the limiting hole 223. The upper end of the wire clamping disc 224 is fixedly connected to the fixing rod 213. The wire clamping disc 224 is a disc with a notch. Wires at the wire holes 222 opposite to the notch of the wire clamping disc 224 can pass through normally. Wires passing through the wire holes 222 opposite to the notch of the wire clamping disc 224 are clamped and fixed by friction with the sidewalls of the wire clamping disc 224 and the wire holes 222.

[0047] Initially, the rotating disk 221 and the wire clamping disk 224 are in contact. After the wire cutting assembly 4 cuts the wire, the left feeding roller group 5 drives the processed wire through the wire hole 222 and the flat recess at the upper end of the wire clamping disk 224. Then, the motor 214 drives the wire to rotate through the rotating disk 221. After the wire rotates, it is clamped and locked by the protrusion of the wire clamping disk 224 and the wire hole 222. When a sufficient number of processed wires are locked in the wire holes 222 around the rotating disk 221, the operator first binds the locked wires and then starts the cylinder 211. The cylinder 211 drives the fixing rod 213 to slide at the upper limit of the base 1 through the fixing rod limit slide groove 212, which in turn drives the wire clamping disk 224 to slide at the upper limit of the rotating disk 221 through the limit hole 223. The wire clamping disk 224 moves away from the rotating disk 221, and the locking of the processed wire is released. The operator then removes the wire and continues to process it.

[0048] This invention allows processed wires to be aligned without manual handling, reducing wasted time.

[0049] The V-shaped wheel shaping mechanism 3 includes: two V-shaped wheels 31, three V-shaped wheels 32, a limiting sliding assembly 33, and a position fixing assembly 34; the three V-shaped wheels 32 are placed at the same height, and the two V-shaped wheels 31 are at the same height below the V-shaped wheels 32, with the three V-shaped wheels 32 and the two V-shaped wheels 31 staggered; the V-shaped wheels 31 are rotatably connected to the base 1, and the V-shaped wheels 32 are connected to the limiting sliding assembly 33; the limiting sliding assembly 33 is connected to the position fixing assembly 34, and both the limiting sliding assembly 33 and the position fixing assembly 34 are connected to the base 1;

[0050] The limiting sliding assembly 33 includes a sliding plate 331 and a limiting groove 332; a limiting groove 332 is provided on the front right side of the base 1, and the sliding plate 331 is slidably connected to the base 1 through the limiting groove 332; the sliding plate 331 is rotatably connected to the V-shaped wheel 32.

[0051] The position fixing component 34 includes a ratchet 341, a locking block 342, a spring 343, an adjusting block 344, and a locking block groove 345; the ratchet 341 is fixedly installed on the right end of the sliding plate 331; the locking block groove 345 is opened on the right end of the base 1, and the locking block groove 345 is located on the right side of the sliding plate 331; the locking block 342 is slidably connected to the base 1 through the locking block groove 345; one end of the spring 343 is fixedly connected to the locking block 342, and the other end of the spring 343 is fixedly connected to the base 1; the locking block 342 is fixedly connected to the adjusting block 344 through a connecting rod, and the adjusting block 344 is located on the right side of the base 1; the locking block 342 engages with the ratchet 341.

[0052] After the operator places the wire to be processed above the V-shaped wheel 31, the sliding plate 331 slides on the base 1 through the limiting groove 332. At this time, the sliding plate 331 can only slide downward under the action of the ratchet 341 and the locking block 342, and cannot slide upward. The sliding plate 331 drives the V-shaped wheel 32 to slide downward. When the V-shaped wheel 31 and the V-shaped wheel 32 cooperate, they clamp the wire. Then the feeding roller group 5 drives the wire to move, so that the wire is pulled under the action of the V-shaped wheel 31 and the V-shaped wheel 32 and no longer bends. When changing to a wire of different diameter, the adjusting block 344 is pulled to the right. The adjusting block 344 drives the locking block 342 to slide to the right through the connecting rod. At this time, the sliding plate 331 is moved upward to the appropriate position. The adjusting block 344 is released, and the spring 343 squeezes the locking block 342 to reset. After the locking block 342 is reset, it continues to cooperate with the ratchet 341 so that the sliding plate 331 can only move downward and cannot move upward.

[0053] This invention allows for the adjustment of the V-shaped wheel shaping mechanism 3 to be completed in one go, reducing the time required for preparation.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
