Description

Technical Field

[0001] This utility model belongs to the field of cable core processing technology, specifically relating to a wire drawing machine inlet bracket for cable core processing. Background Technology

[0002] Cable core wire drawing machines are widely used in the forming and processing of various metal core materials such as copper wire, aluminum wire, and stainless steel wire. The wire feed bracket before drawing is the core structure that guides the raw material wire to enter the drawing die stably. Its design directly affects the drawing quality, wire life and equipment operation stability.

[0003] Currently, when processing cable cores, the inlet support is usually fixed at a high position by a pole frame, and the copper wire reel is placed directly on the ground below one side of the inlet support. The copper wire is introduced upward into one side of the inlet support, and then led downward from the other side. Then, the copper wire is guided into the inlet mold wheel for wire pulling through the guide wheels set on the ground.

[0004] When copper wire is drawn from the wire spool, due to the inertia of winding, it retains a certain degree of curvature as it is pulled upwards. Although the wire gradually straightens relatively through the tension of the clamping and guide wheels on the wire feed bracket, it is still affected by the curvature during transmission in the guide wheels and downward output. This causes the wire to bounce during transmission, and the faster the feed speed, the more severe the bouncing. This not only causes scratches and damage to the wire surface but also easily leads to deviations in the wire's entry angle into the die. Especially during high-speed, large-diameter core wire drawing, the wire is prone to bouncing, slippage, trembling, or warping as it travels from the wire feed bracket to the die base. This not only easily damages the core wire itself but also accelerates the wear of the guide wheels and the die, affecting the quality of the finished product. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a wire drawing machine feed bracket for cable core wire processing. This solves the problem that when copper wire is drawn from the wire spool, due to the inertia during winding, the copper wire retains a certain degree of curvature as it is pulled upwards. Although the wire gradually straightens relatively through the transmission tension of the clamping rollers and guide rollers on the feed bracket, it is still affected by the curvature during transmission in the guide rollers and downward output. This causes the copper wire to bounce during transmission, and the faster the feed speed, the more severe the bouncing. This not only causes scratches and damage to the wire surface but also easily leads to deviations in the wire's entry angle into the die due to the bouncing. Especially during high-speed, large-diameter core wire drawing, the wire is prone to bouncing, slippage, trembling, or curling during its journey from the feed bracket to the die base. This not only easily damages the core wire itself but also accelerates the wear of the guide rollers and die, affecting the quality of the finished product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire drawing machine feed bracket for cable core processing, comprising a T-shaped support, a crossbar welded and fixedly mounted on one side of the T-shaped support, the T-shaped support being perpendicular to the crossbar, guide wheels symmetrically mounted on both sides of the upper side of the crossbar, and wire clamping and securing mechanisms symmetrically fixedly mounted at both ends of the lower side of the crossbar. The wire clamping and securing mechanism includes a fixed plate, a diagonal bar, a vertical bar, a first clamping roller, a fixed frame, an electro-hydraulic telescopic rod, a pressure rod, a second clamping roller, a wire inlet end piece, a wire inlet circular hole, and an L-shaped bracket. The fixed plate is bolted and fixedly mounted on the lower side of the crossbar. A diagonal brace is fixedly installed on the side of the fixed plate that is far away from each other. The diagonal brace is inclined downwards towards the side away from the horizontal frame. A vertical pole is fixedly installed vertically downwards at the lower end of the diagonal brace. A clamping roller 1 is equidistantly rotatably installed on the upper side of the vertical pole that is far away from the horizontal frame. A fixing frame is symmetrically fixed on the side of the vertical pole that is far away from the horizontal frame. An electro-hydraulic telescopic rod is fixedly installed on the side of the fixing frame that is far away from the horizontal frame. A pressure rod is fixedly connected to the output end of the electro-hydraulic telescopic rod facing the vertical pole. A clamping roller 2 is equidistantly rotatably installed on the side of the pressure rod that is close to the vertical pole. The clamping roller 2 and clamping roller 1 are pressed together in a one-to-one correspondence.

[0007] The beneficial effects of this utility model are as follows: it enables the wire to maintain a stable transmission and straightening state when it is input and output in this device, thereby ensuring that the wire remains stable during transmission in this device and does not jump, thus avoiding scratches and damage to the wire surface caused by jumping, avoiding deviation of the wire entry angle due to jumping, and preventing damage to the core wire body when the wire is fed at high speed, and preventing accelerated wear of the guide wheel and mold, thereby avoiding adverse effects on the quality of the finished product.

[0008] To ensure the wire is relatively stably fed between clamping roller one and clamping roller two;

[0009] As a further improvement to the above technical solution: a wire inlet end piece is fixedly provided on the lower side of the end of the upright away from the crossbar, and a wire inlet hole is provided through the upper side of the wire inlet end piece.

[0010] The beneficial effect of this improvement is that it allows the wire to be introduced relatively stably between the first and second clamping rollers.

[0011] The ring shape reduces scratching and wear on the wire surface;

[0012] As a further improvement to the above technical solution: an annular body is fixedly provided on the inner side of the inlet circular hole, and the cross-section of the annular body is circular.

[0013] The beneficial effect of this improvement is that the ring shape can reduce scratching and wear on the wire surface.

[0014] To increase the structural stability of the uprights;

[0015] As a further improvement to the above technical solution: an L-shaped bracket is welded and fixed between the fixing plate and the upright.

[0016] The beneficial effect of this improvement is that it increases the structural stability of the uprights.

[0017] To ensure the structural strength and verticality of the T-shaped support;

[0018] As a further improvement to the above technical solution: angle steel is welded and fixed to the bottom sides of both sides of the T-shaped support.

[0019] The beneficial effects of this improvement are: it makes it easier to ensure the structural strength and verticality of the T-shaped support.

[0020] To allow for adjusting the height of the guide wheel as needed;

[0021] As a further improvement to the above technical solution: wheel rods are rotatably provided at the center of both sides of the guide wheel, and slots are provided through the lower side of each wheel rod. Screws are welded and fixedly provided on both sides of the crossbar corresponding to the wheel rods, and nuts are threaded through the slots of each screw.

[0022] The beneficial effect of this improvement is that the guide wheel rod can be slid up and down along the slot, and then the nut can be tightened to fix the wheel rod, which is used to adjust the height of the guide wheel as needed.

[0023] To ensure the stability of the wheel shaft;

[0024] As a further improvement to the above technical solution: clamping rods are symmetrically fixed on both sides of the crossbar corresponding to the wheel rods, the wheel rods are inserted and clamped between the clamping rods, and the grooves pass through the bottom side of the wheel rods.

[0025] The beneficial effects of this improvement are as follows: a clamping rod is set to clamp and limit the wheel rod to ensure the stability of the wheel rod; the groove passes through the bottom side of the wheel rod; pulling the wheel rod upward causes the screw to disengage from the groove, which is used for disassembling and replacing the guide wheel.

[0026] To increase the buffering effect on the wire and the friction transmission effect;

[0027] As a further improvement to the above technical solution: both the second and the first clamping rollers are covered with a rubber layer on their outer sides.

[0028] The beneficial effects of this improvement are: increased buffering of the wire and improved friction transmission effect.

[0029] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0037] like Figure 1 — Figure 5As shown: A wire drawing machine feed bracket for cable core processing includes a T-shaped support 1. A crossbar 2 is welded and fixedly installed on the upper side of one side of the T-shaped support 1. The T-shaped support 1 is perpendicular to the crossbar 2. Guide wheels 3 are symmetrically arranged on both sides of the upper side of the crossbar 2. A wire clamping mechanism 4 is symmetrically fixedly installed at both ends of the lower side of the crossbar 2. The wire clamping mechanism 4 includes a fixed plate 41, a diagonal bar 42, a vertical bar 43, a clamping roller 44, a fixed frame 45, an electric hydraulic telescopic rod 46, a pressure rod 47, a clamping roller 48, a wire inlet end piece 49, a wire inlet round hole 410, and an L-shaped bracket 411. The fixed plate 41 is bolted to the lower side of the crossbar 2. The diagonal bar 42 is fixedly installed on the side of the fixed plate 41 that is far apart from each other. The inclined rod 42 is inclined downwards towards the side away from the horizontal support rod 2. A vertical pole 43 is fixedly fixed at the lower end of the inclined rod 42. A clamping roller 44 is equidistantly rotatably mounted on the upper side of the vertical pole 43 away from the horizontal support rod 2. A fixing frame 45 is symmetrically fixed on the side of the vertical pole 43 away from the horizontal support rod 2, outside the clamping roller 44. An electro-hydraulic telescopic rod 46 is fixedly mounted on the side of the fixing frame 45 away from the horizontal support rod 2. A pressure rod 47 is fixedly connected to the output end of the electro-hydraulic telescopic rod 46 facing the vertical pole 43. A clamping roller 48 is equidistantly rotatably mounted on the side of the pressure rod 47 near the vertical pole 43. The clamping roller 48 and the clamping roller 44 are pressed together one-to-one, ensuring stable wire input and output in this device. The transmission and straightening states ensure that the wire remains stable during transmission within the device, preventing it from jumping and causing scratches or damage to the wire surface. This also prevents the wire's entry angle from shifting due to jumping. During high-speed wire feeding, it is less likely to damage the core wire body and accelerate wear on the guide rollers and mold, thus avoiding adverse effects on the finished product quality. A wire inlet end piece 49 is fixedly installed on the lower side of the end of the upright 43 away from the horizontal frame 2. A wire inlet circular hole 410 is opened through the upper side of the wire inlet end piece 49, allowing the wire to be relatively stably guided between the clamping rollers 44 and 48. An annular body with a circular cross-section is fixedly installed inside the wire inlet circular hole 410. This annular body reduces scratches and wear on the wire surface. An L-shaped bracket 411 is welded and fixed between the fixed plate 41 and the upright 43 to increase the structural stability of the upright 43. Angle steel is welded and fixed to the bottom sides of both sides of the T-shaped support 1 to ensure the structural strength and verticality of the T-shaped support 1. Wheel rods 31 are rotatably mounted on the center of both sides of the guide wheel 3. The lower side of each wheel rod 31 has a through groove 32. Screws 21 are welded and fixed to both sides of the crossbar 2 corresponding to the wheel rods 31. Each screw 21 is threaded through the groove 32 and connected to a nut. The wheel rod 31 slides up and down along the groove 32, and then the nut is tightened to fix the wheel rod 31. This is used to adjust the height of the guide wheel 3 as needed. Clamping rods 22 are symmetrically fixed to both sides of the crossbar 2 corresponding to the wheel rods 31.The wheel rod 31 is inserted and snapped between the clamping rods 22. The groove 32 extends through the bottom side of the wheel rod 31. The clamping rods 22 are used to clamp and restrict the wheel rod 31, ensuring the stability of the wheel rod 31's vertical sliding. Pulling the wheel rod 31 upwards causes the screw 21 to disengage from the groove 32, facilitating the removal and replacement of the guide wheel 3. The outer sides of both the second clamping roller 48 and the first clamping roller 44 are covered with a rubber layer to increase the cushioning effect on the wire and the friction transmission effect.

[0038] Working principle and usage process of this utility model:

[0039] In use, mounting holes are made on the bottom side of the T-shaped support 1. The T-shaped support 1 is fixed to the upright frame through the mounting holes, thereby fixing the device to the top of the upright frame. A wire roll is placed on the ground directly below the wire clamping mechanism 4 on one end of the crossbar 2. The wire is introduced upward into the wire inlet hole 410, passes upward through the wire inlet end piece 49, and then passes upward between the clamping roller 1 44 and the clamping roller 2 48. The electric hydraulic telescopic rod 46 is activated, and the output end of the electric hydraulic telescopic rod 46 extends, pushing the pressure rod 47 to drive the clamping roller 2 48 to stably clamp the wire on the clamping roller 1 44. Then, the wire is introduced upward into the upper side of the guide wheel 3, and then from the guide wheel 3 at the other end of the crossbar 2. The wire is guided down from the upper side by the guide wheel 3. After being guided down by the guide wheel 3, the wire passes through the clamping rollers 48 and 44 of the clamping mechanism 4 on the other side. Then it is led out through the inlet hole 410 of the inlet end piece 49 at the lower end. The clamping rollers 48 and 44 on the lead-out side also clamp the wire. Finally, the wire is guided horizontally out by the guide wheel set on one side of the bottom of the pole frame and introduced into the wire drawing mold. This guide wheel is an external independent device, set according to the height and direction of the wire drawing mold. The guide wheel is set directly below the clamping mechanism 4 on the wire output side so that the wire can remain vertical when it is led out downwards. In the above process, the wire is drawn from the wire coil After being drawn out, the wire is initially released in a spiral shape, similar to a spring. The wire maintains a spirally bent state. However, the wire used for drawing is generally more flexible and does not solidify like a spring. During the upward pulling process, it gradually straightens under the gravity of the subsequent wire, but it will not be completely straight and will still have irregular bends. Through the wire inlet hole 410 of the wire inlet end piece 49, the newly unwound bent wire can be relatively stably introduced between the clamping roller 1 44 and the clamping roller 2 48. After the wire passes between the clamping roller 1 44 and the clamping roller 2 48 of the input side clamping mechanism 4, it is clamped and restricted by the clamping roller 1 44 and the clamping roller 2 48 and subjected to the tension during traction, causing the wire to... Under stable straightening action, the bent wire is further straightened and can be stably input into the guide roller 3. Similarly, when the wire is output downward from the clamping and fixing mechanism 4 on the output side, it will also maintain stable downward transmission and straightening action. This ensures that the wire can maintain a stable transmission and straightening state when it is input and output in this device, thus ensuring that the wire can remain stable during transmission in this device and will not jump. This avoids scratches and damage to the wire surface caused by jumping, avoids deviation of the wire entry angle due to jumping problems, and is less likely to damage the core wire body when the wire is fed at high speed. It also does not accelerate the wear of the guide roller and the mold, thus avoiding adverse effects on the quality of the finished product.
