An alloy wire straightening and cutting device and its working method

Abstract

The present invention is applicable to the technical field of alloy wire processing, and provides an alloy wire straightening and cutting device and its working method, including a working frame, a straightening component, a blanking component and a guiding component installed on the top of the working frame. The guiding component is located between the straightening component and the blanking component. A traction component is installed on the top of the guiding component, and the traction component extends above the blanking component. An intercepting component is installed on the top of the straightening component. This device solves the problems that in a mobile truncation station, the wire is bent due to the resistance generated by slipping on the bearing mechanism, and the end of the wire is bent due to the friction between the thin wire and the surface when the bearing mechanism feeds at an inclination. This device uses an electric slide rail to drive the grasping mechanism to move, so that the clamping cylinder clamps the clamped alloy wire, and the overall movement of the grasping mechanism completes the traction. When the alloy wire is pulled to a certain length, it is truncated to prevent the alloy wire from sagging and rubbing against the blanking plate, resulting in bending.

Description

Technical Field

[0001] The present invention relates to the technical field of alloy wire processing, and more specifically, it relates to an alloy wire straightening and cutting device and its working method. Background Art

[0002] In the metal processing and manufacturing industries, alloy wires are widely used in various fields such as construction engineering, machinery manufacturing, and electronic equipment due to their excellent mechanical properties and corrosion resistance. Alloy wires usually need to undergo strict straightening and truncation processes to adapt to different application scenarios and technical requirements.

[0003] Currently, when the existing devices perform straightening and cutting on alloy wires, the specific process includes unwinding the alloy wire coil, passing through the straightening mechanism and the truncation mechanism, and finally producing qualified alloy wire segments. However, during the process of truncating the alloy wire, due to the softness of the alloy wire, the wire is prone to sagging after extending a certain distance in the air. This causes the already straightened alloy wire to bend again after truncation, thereby affecting the accuracy of the cut, resulting in length fluctuations and surface damage, especially being particularly obvious for titanium wires with a cold working hardened layer on the surface. This sagging not only makes the cut of the truncated alloy wire inclined but also increases the risk of surface damage. Therefore, the staff has made improvements to this phenomenon by adding a carrying mechanism behind the truncation mechanism, enabling the alloy wire to be lifted to a certain height before reaching the truncation position to reduce its sagging in the suspended state. By truncating the alloy wire with a mobile truncation mechanism, synchronous height tracking and dynamic pressure regulation of the wire are achieved. This improvement has indeed reduced the sagging phenomenon of soft wires during truncation, improving the processing accuracy and efficiency.

[0004] However, there are still some problems in actual operation. For example, the mobile truncation station may push the wire to move. After adding the carrying mechanism, the wire will slip on the stacked wires during or before wire breaking, generating resistance and bending. Even if the carrying mechanism is set to tilt and feed the wire once every truncation to discharge the already truncated wire, the friction between the thin wire and the surface of the carrying mechanism will also cause the problem of wire end bending, thereby affecting the overall processing quality. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an alloy wire straightening and cutting device and its working method.

[0006] To achieve the above object, the present invention provides the following technical solutions: An alloy wire straightening and cutting device, including a working frame, a straightening component, a blanking component and a guiding component installed on the top of the working frame. The guiding component is located between the straightening component and the blanking component. A traction component is installed on the top of the guiding component, and the traction component extends above the blanking component. A cutting component is installed on the top of the straightening component.

[0007] The cutting component includes an adjusting cylinder installed on the top of the straightening component and a bearing plate connected to the end of the adjusting cylinder. Two cutting knives slide on the side of the bearing plate away from the adjusting cylinder.

[0008] The blanking component includes a blanking cylinder installed on the top of the working frame, and the output end of the blanking cylinder is connected to a blanking plate.

[0009] The traction component includes a U-shaped frame installed on the top of the guiding component, and an electric slide rail one and an electric slide rail two rotatably installed on the top of the U-shaped frame. Gripping mechanisms slide on the bottoms of both the electric slide rail one and the electric slide rail two.

[0010] The present invention is further provided as follows: The straightening component includes a horizontal straightening mechanism and a vertical straightening mechanism installed on the top of the working frame. The cutting component is installed on one side of the top of the vertical straightening mechanism. Two driving wheels are rotatably connected to the front surface of the vertical straightening mechanism. A driving motor is installed on the top of the working frame, and the output end of the driving motor penetrates through the vertical straightening mechanism and is connected to one of the driving wheels. Two groups of guiding grooves are installed on the front surface of the vertical straightening mechanism, and both groups of guiding grooves are located on both sides of the joint of the two driving wheels.

[0011] The horizontal straightening mechanism includes a horizontal straightening frame installed on the top of the working frame. Three first straightening wheels and two first auxiliary wheels are arranged on the top of the horizontal straightening frame. The two first auxiliary wheels are respectively located at positions opposite to the middles of the adjacent two first straightening wheels.

[0012] The vertical straightening mechanism includes a vertical plate installed on the top of the working frame. Three second auxiliary wheels and two second straightening wheels are arranged on one side of the vertical plate. The two second straightening wheels are respectively located at positions opposite to the middles of the adjacent two second auxiliary wheels.

[0013] The present invention is further provided as follows: The adjusting cylinder is installed on one side of the top of the vertical plate. Two guide rails are horizontally installed on the side of the bearing plate away from the vertical plate. The two cutting knives are respectively slidably connected to the side walls of the two guide rails. Guide columns are connected to the side walls of the two cutting knives. A vertical cylinder is vertically installed on the side wall of the bearing plate, and a push plate is installed at the end of the piston rod of the vertical cylinder. Two chutes are symmetrically opened on the side wall of the push plate, and the two guide columns are respectively slidably connected to the interiors of the two chutes.

[0014] By adopting the above technical solution, when the electric slide rail drives the corresponding grasping mechanism to move, the corresponding sliding frame moves synchronously. The clamping cylinder can be adjusted to the position where the alloy wire needs to be clamped and clamp the outer wall of the alloy wire. Then, through the overall movement of the grasping mechanism, the alloy wire is tractioned. When the alloy wire is tractioned, the grasping mechanism on the second electric slide rail is in a standby position on one side of the guiding component. After the alloy wire is tractioned to a certain length, the guiding cylinder pulls the first guiding wheel away from the second guiding wheel, and the alloy wire is no longer guided, avoiding the problem that the alloy wire sags and rubs against the blanking plate, resulting in bending.

[0015] The present invention is further configured as: the guiding component includes a bracket installed on the top of the working frame. The bottom of the bracket is rotatably connected with a first guiding wheel and a second guiding wheel by means of a resistance bearing. A through groove is opened at the top of the bracket. A guiding cylinder is installed on the side wall of the bracket. The end of the piston rod of the guiding cylinder extends into the interior of the through groove and is connected to the resistance bearing of the first guiding wheel.

[0016] The present invention is further configured as: a ring body is connected to the bottom of the first guiding wheel, and an I-shaped wheel is installed at the bottom of the second guiding wheel. The outer wall of the ring body is inserted into the interior of the I-shaped wheel, and a first inclined portion is opened at the edge position of the top surface of the I-shaped wheel.

[0017] By adopting the above technical solution, when the first guiding wheel and the second guiding wheel are separated, the cooperation of the ring body and the I-shaped wheel enables the alloy wire to still be in the position between the first guiding wheel and the second guiding wheel without falling. When the cutting component can push the cut alloy wire to move and separate from the conveyed alloy wire, it prevents the alloy wire from sagging and separating from the guiding component.

[0018] The present invention is further configured as: two rotating motors are installed on the inner top wall of the U-shaped frame. The output ends of the two grasping mechanisms respectively penetrate through the top of the U-shaped frame and are connected to the first electric slide rail and the second electric slide rail.

[0019] Each of the two groups of grasping mechanisms includes a sliding frame and a lifting cylinder installed on the top of the sliding frame. The end of the piston rod of the lifting cylinder penetrates through the sliding frame and is connected to a clamping cylinder. Both output ends of the clamping cylinder are connected with clamping plates, and two groups of clamping and warping mechanisms are installed between two corresponding clamping plates.

[0020] The present invention is further configured as follows: The clamping and warping mechanism includes a first hinge seat installed on the side wall of the corresponding clamping plate and a limiting groove opened on the side wall of the first hinge seat. A sliding rod penetrates through the inside of the limiting groove. A spring is connected between the outer side wall of the sliding rod and the inner wall of the limiting groove. The outer side wall of the sliding rod is connected with a second hinge seat. A rubber clamping block is hinged inside the second hinge seat. A support rod is horizontally connected inside the first hinge seat. The support rod is in contact with the bottom of the second hinge seat.

[0021] The present invention is further configured as follows: An arc-shaped groove is opened on one side of the rubber clamping block away from the second hinge seat. A scraping part is opened at the bottom of the arc-shaped groove. A second inclined part is opened at the inner wall position of the first hinge seat. An adapting chamfer is opened at the top of one side of the second hinge seat away from the rubber clamping block. The adapting chamfer is adapted to the second inclined part.

[0022] By adopting the above technical solution, when the alloy wire is pulled by the traction assembly, since both the first guide wheel and the second guide wheel are rotationally connected through resistance bearings, there is rotational resistance when the first guide wheel and the second guide wheel rotate. The alloy wire drives the first guide wheel and the second guide wheel to roll during the conveying process, and the rotational speed of the first guide wheel and the second guide wheel is reduced through the rotational resistance, so that the traction assembly straightens the alloy wire. Moreover, by the guiding of the guiding assembly and the pulling of the traction assembly, it is ensured that the alloy wire will not be frictionally bent on the top of the blanking plate.

[0023] The lifting cylinder drives the clamping cylinder and the clamping plate to move downward. The clamping and warping mechanism on the clamping plate fits with the top surface of the blanking plate. Subsequently, the clamping cylinder makes the two clamping plates approach each other, and the two sets of clamping and warping mechanisms approach accordingly. The rubber clamping block in the clamping and warping mechanism slides on the top of the blanking plate, and uses the scraping part thereon to scoop up the alloy wire attached to the top of the blanking plate, and then clamps and squeezes the alloy wire. At this time, the relevant hinge seats act on each other, the sliding rod compresses the spring, and the second hinge seat moves upward obliquely under the influence of the inclined part, so that the clamped alloy wire is lifted. Finally, the electric slide rail drives the grasping mechanism and the alloy wire to be conveyed forward, avoiding frictional bending of the end of the alloy wire with the blanking plate.

[0024] A working method for straightening and cutting an alloy wire, using an alloy wire straightening and cutting device as described above, includes the following steps:

[0025] S1. Pass the unrolled alloy wire through the straightening assembly, the intercepting assembly and the guiding assembly in sequence, and use the straightening assembly to straighten the alloy wire.

[0026] S2. The straightened alloy wire is guided and transported by the guide component after passing through the intercepting component, and then assisted in traction by the grabbing mechanism on the electric slide rail 1, and the grabbing mechanism on the electric slide rail 2 is kept in reserve. When the alloy wire is pulled to a suitable length, the guide component cancels the guiding and transporting of the alloy wire, and uses the intercepting component to move and track, and assists in cutting the alloy wire. The cut alloy wire falls onto the surface of the dumping plate, and then the dumping cylinder drives the dumping plate to swing, thereby guiding and discharging the alloy wire, and then the dumping plate returns to a horizontal state and is kept in reserve.

[0027] S3. After the alloy wire is cut off, the straightened alloy wire continues to pass through the inside of the guide assembly, and the guide assembly re-clamps and guides the alloy wire that continues to be transported. The grabbing mechanism on the electric slide rail 2 clamps and pulls the alloy wire, and cuts and unloads the material according to the above steps. At the same time, the electric slide rail 1 drives the grabbing mechanism to swing away from the alloy wire conveying direction, and the grabbing mechanism corresponding to the electric slide rail 1 moves toward the direction close to the guide assembly. After moving into place, the electric slide rail 1 is straightened, and the corresponding grabbing mechanism is reset to the waiting position to wait for the next traction operation.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] (1) By setting up electric slide rail 1, electric slide rail 2 and two groups of grabbing mechanisms, when the electric slide rail drives the corresponding grabbing mechanism to move, the corresponding sliding frame moves synchronously, and the clamping cylinder can be adjusted to the position where the alloy wire needs to be clamped and clamp the outer wall of the alloy wire. Then, through the overall movement of the grabbing mechanism, the alloy wire is pulled and pulled. When the alloy wire is pulled, the grabbing mechanism on the electric slide rail 2 is in a standby position on one side of the guide assembly. After the alloy wire is pulled to a certain length, the guide cylinder pulls the first guide wheel away from the second guide wheel, and the alloy wire is no longer guided, thereby avoiding the problem of the alloy wire sagging and rubbing against the dumping plate to cause bending.

[0030] (2) By setting up a guide assembly and a traction assembly, when the alloy wire is pulled by the traction assembly, since the first guide wheel and the second guide wheel are rotatably connected through a resistance bearing, there is rotational resistance when the first guide wheel and the second guide wheel rotate. During the conveying process, the alloy wire drives the first guide wheel and the second guide wheel to roll, and the rotational speed of the first guide wheel and the second guide wheel is reduced by the rotational resistance, so that the traction assembly straightens the alloy wire, and utilizes the guidance of the guide assembly and the pulling of the traction assembly to ensure that the alloy wire will not bend due to friction on the top of the pouring plate.

[0031] (3) Through the ring body and the spool, when the first guide wheel and the second guide wheel are separated, the ring body and the spool cooperate to keep the alloy wire still in the position between the first guide wheel and the second guide wheel without dropping. When the cutting component can push the cut alloy wire to move and separate from the conveyed alloy wire, it prevents the alloy wire from sagging and separating from the guiding component.

[0032] (4) By setting the clamping and lifting mechanism, the lifting cylinder drives the clamping cylinder and the clamping plate to move downward. The clamping and lifting mechanism on the clamping plate fits with the top surface of the blanking plate. Subsequently, the clamping cylinder makes the two clamping plates approach each other, and the two groups of clamping and lifting mechanisms approach accordingly. The rubber clamping blocks in the clamping and lifting mechanism slide on the top of the blanking plate, and use the scraping parts on them to shovel up the alloy wire attached to the top of the blanking plate. Then, the alloy wire is clamped and squeezed. At this time, the relevant hinge seats interact, the sliding rod compresses the spring, and the second hinge seat moves upward obliquely under the influence of the inclined part, so that the clamped alloy wire is lifted. Finally, the electric slide rail drives the grasping mechanism and the alloy wire to be conveyed forward, avoiding the friction and bending of the end of the alloy wire with the blanking plate.

[0052] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0053] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0054] Please refer to Figures 1 - 10 , the present invention provides the following technical solutions:

[0055] Embodiment 1, refer to Figure 1 and Figure 2, an alloy wire straightening and cutting device, including a working frame 1 and a straightening component 2 installed on the top of the working frame 1. The straightening component 2 is used for straightening the alloy wire. The specific structure of the straightening component 2 is as follows:

[0056] Refer to Figure 1 and Figure 2 , the straightening component 2 includes a horizontal straightening mechanism 21 and a vertical straightening mechanism 22 installed on the top of the working frame 1. The horizontal straightening mechanism 21 and the vertical straightening mechanism 22 respectively straighten the unrolled alloy wire in the horizontal and vertical directions. The specific structure of the horizontal straightening mechanism 21 is as follows:

[0057] Refer to Figure 1 and Figure 2 , the horizontal straightening mechanism 21 includes a horizontal straightening frame 211 installed on the top of the working frame 1. Three first straightening wheels 213 and two first auxiliary wheels 214 are arranged on the top of the horizontal straightening frame 211. The two first auxiliary wheels 214 are respectively located at positions opposite to the middle parts of two adjacent first straightening wheels 213. Two first straightening cylinders 212 are installed on one side of the horizontal straightening frame 211. The piston rods of the two first straightening cylinders 212 are respectively rotationally connected to the two first auxiliary wheels 214. The alloy wire passes through the space between the first straightening wheels 213 and the first auxiliary wheels 214 for horizontal straightening. The strength of horizontal straightening can be achieved by moving the first auxiliary wheels 214. Specifically, the corresponding first auxiliary wheel 214 is pushed by the first straightening cylinder 212 to move, thereby adjusting the distance between the first auxiliary wheel 214 and the corresponding two first straightening wheels 213, and further adjusting the extrusion degree of the first auxiliary wheel 214 on the alloy wire.

[0058] Refer to Figure 1 and Figure 2 , the specific structure of the vertical straightening mechanism 22 is as follows:

[0059] The vertical straightening mechanism 22 includes a vertical plate 221 installed on the top of the working frame 1. Three second auxiliary wheels 224 and two second straightening wheels 222 are arranged on one side of the vertical plate 221. The two second straightening wheels 222 are respectively located at positions opposite to the middle parts of two adjacent second auxiliary wheels 224. Two second straightening cylinders 223 are vertically installed on the top of the vertical plate 221. The piston rods of the two second straightening cylinders 223 are respectively rotationally connected to the two second auxiliary wheels 224. The straightening method of the vertical straightening mechanism 22 is the same as that of the horizontal straightening mechanism 21. The alloy wire passes through the space between the second straightening wheels 222 and the second auxiliary wheels 224 for vertical straightening. The strength of vertical straightening can be achieved by controlling the movement of the second auxiliary wheels 224 by the second straightening cylinders 223.

[0060] Refer to Figure 1 and Figure 2, two driving wheels 24 are rotatably connected to the front surface of the vertical straightening mechanism 22. A driving motor 23 is installed on the top of the working frame 1. The output end of the driving motor 23 penetrates through the vertical straightening mechanism 22 and is connected to one of the driving wheels 24. Two groups of guide grooves 25 are installed on the front surface of the vertical straightening mechanism 22. Both groups of guide grooves 25 are located on both sides of the fitting position of the two driving wheels 24. The straightened alloy wire passes through the guide grooves 25 and between the two driving wheels 24. At this time, the driving motor 23 drives one of the driving wheels 24 to rotate, and the two driving wheels 24 rotate in opposite directions through the extrusion and friction force on the alloy wire, thereby assisting in conveying the alloy wire.

[0061] Refer to Figures 1 - 3 , a cutting component 3 is installed on the top of the vertical plate 221. The cutting component 3 is used for tracking and assisting in cutting the alloy wire. The specific structure of the cutting component 3 is as follows:

[0062] Refer to Figures 1 - 3 , the cutting component 3 includes an adjusting cylinder 38 installed on the top of the orthopedic component 2 and a bearing plate 31 connected to the end of the adjusting cylinder 38. Two cutting knives 36 slide on the side of the bearing plate 31 away from the adjusting cylinder 38. The adjusting cylinder 38 is installed on one side of the top of the vertical plate 221. Two guide rails 35 are horizontally installed on the side of the bearing plate 31 away from the vertical plate 221. The two cutting knives 36 are respectively slidably connected to the side walls of the two guide rails 35. Guide columns 37 are connected to the side walls of the two cutting knives 36. A vertical cylinder 32 is vertically installed on the side wall of the bearing plate 31. The end of the piston rod of the vertical cylinder 32 is installed with a push plate 33. Two chute grooves 34 are symmetrically opened on the side wall of the push plate 33. The two guide columns 37 are respectively slidably connected to the interiors of the two chute grooves 34. The adjusting cylinder 38 is used to drive the bearing plate 31 to move, thereby adjusting the movement of the cutting knives 36 installed on the side wall of the bearing plate 31, so that the cutting knives 36 can cut the alloy wire at a suitable position. The vertical cylinder 32 is used to drive the push plate 33 to move up and down. During the movement of the push plate 33, the guide columns 37 are pulled or pushed through the chute grooves 34. During the sliding process of the guide columns 37, the cutting knives 36 are driven to move. Since the cutting knives 36 are restricted by the guide rails 35, the cutting knives 36 slide horizontally on the guide rails 35.

[0063] Specifically, when the alloy wire is being conveyed, the adjustment cylinder 38 pushes the carrier plate 31 to move, and the moving speed is the same as the conveying speed of the alloy wire. Then, the vertical cylinder 32 pushes the push plate 33 upward, causing the guide post 37 to slide inside the corresponding chute 34. The cutting knife 36 corresponding to the guide post 37 slides on the side wall of the guide rail 35 under the guidance of the chute 34, causing the two cutting knives 36 to approach each other to cut the alloy wire. When the alloy wire is cut, the adjustment cylinder 38 accelerates the speed of pushing the carrier plate 31 to move, and the moving speed is greater than the conveying speed of the alloy wire. The cut alloy wire quickly moves forward a certain distance, causing the cut alloy wire to be separated from the conveyed alloy wire by a certain distance, which facilitates blanking and avoids interference between the cut alloy wire and the conveyed alloy wire during the blanking process.

[0064] Refer to Figures 1 - 4 , a blanking assembly 4 is installed on the top of the working frame 1. The blanking assembly 4 is used for tilting and blanking the cut alloy wire. The specific structure of the blanking assembly 4 is as follows:

[0065] Refer to Figures 1 - 4 , the blanking assembly 4 includes a blanking cylinder 41 installed on the top of the working frame 1. The output end of the blanking cylinder 41 is connected to a blanking plate 42. The blanking cylinder 41 is used to drive the blanking plate 42 to swing. And a protrusion is provided on one side of the top of the blanking plate 42. This protrusion is used to block the alloy wire. When the blanking plate 42 is in a horizontal state, the cut alloy wire falls onto the top of the blanking plate 42 for loading. When the alloy wire needs to be blanked, the blanking plate 42 tilts downward to the side away from the protrusion, causing the alloy wire to fall along the inclined angle and accumulate inside the external collection box.

[0066] And each time the cutting assembly 3 cuts the alloy wire once, the blanking assembly 4 swings once, avoiding the situation where the cut alloy wire accumulates on the top of the blanking plate 42 and causes surface damage due to mutual scraping between the alloy wires.

[0067] Embodiment 2. After the cutting assembly 3 cuts the alloy wire, there will be a situation where the wire is pushed to move. Whether the wire is conveyed after or before wire breaking, it will slide on the stacked wires and generate resistance and bending. Even if the blanking assembly 4 is set to tilt and feed once every time it cuts, and the already cut wire is discharged, the friction between the thin wire and the surface of the blanking assembly 4 will also cause the problem of wire end bending, thus affecting the overall processing quality.

[0068] Therefore, a guiding component 5 is installed at the top of the working rack 1. The guiding component 5 is located between the orthopedic component 2 and the discharging component 4. A traction component 6 is installed at the top of the guiding component 5. The traction component 6 extends above the discharging component 4. Both the guiding component 5 and the traction component 6 are used to guide and convey the alloy wire. That is, the alloy wire passes through the guiding component 5 and the traction component 6 in sequence. And the guiding component 5 is used to clamp the alloy wire, while the traction component 6 clamps and pulls the alloy wire, causing the alloy wire to remain in a straight state and avoiding the problem that the end of the wire bends due to friction when the alloy wire is conveyed on the top of the discharging component 4.

[0069] Refer to Figure 1 and Figure 5 , the specific structure of the guiding component 5 is as follows:

[0070] The guiding component 5 includes a bracket 51 installed at the top of the working rack 1. The bottom of the bracket 51 is rotatably connected with a first guiding wheel 53 and a second guiding wheel 54 by a resistance bearing. A through groove is opened at the top of the bracket 51. A guiding cylinder 52 is installed on the side wall of the bracket 51. The end of the piston rod of the guiding cylinder 52 extends into the through groove and is connected to the resistance bearing of the first guiding wheel 53. The alloy wire passes between the first guiding wheel 53 and the second guiding wheel 54. When the alloy wire is pulled by the traction component 6, since both the first guiding wheel 53 and the second guiding wheel 54 are rotatably connected by a resistance bearing, there is a rotational resistance when the first guiding wheel 53 and the second guiding wheel 54 rotate. The alloy wire drives the first guiding wheel 53 and the second guiding wheel 54 to roll during the conveying process, and the rotational speed of the first guiding wheel 53 and the second guiding wheel 54 is reduced by the rotational resistance, causing the traction component 6 to straighten the alloy wire. Moreover, by the guiding of the guiding component 5 and the pulling of the traction component 6, it is ensured that the alloy wire will not be frictionally bent on the top of the discharging plate 42.

[0071] Refer to Figure 1 , Figure 5 , Figure 7 and Figure 8 , the specific structure of the traction component 6 is as follows:

[0072] The traction assembly 6 includes a U-shaped frame 61 installed on the top of the guiding assembly 5, an electric slide rail 62 and an electric slide rail 63 that rotate on the top of the U-shaped frame 61. A grasping mechanism 64 slides at the bottom of both the electric slide rail 62 and the electric slide rail 63. Two rotating motors 65 are installed on the inner top wall of the U-shaped frame 61. The output ends of the two grasping mechanisms 64 respectively penetrate the top of the U-shaped frame 61 and are connected to the electric slide rail 62 and the electric slide rail 63. Both the electric slide rail 62 and the electric slide rail 63 are stepper motor linear guide screw slider modules, which are not specifically defined here. Both the electric slide rail 62 and the electric slide rail 63 can drive the corresponding grasping mechanism 64 to move, thereby adjusting the clamping position of the alloy wire. And the rotating motor 65 is used to drive the corresponding electric slide rail 62 or electric slide rail 63 to swing, so that the grasping mechanism 64 can be moved away from the conveying direction of the alloy wire.

[0073] Both groups of grasping mechanisms 64 include a sliding frame 641 and a lifting cylinder 642 installed on the top of the sliding frame 641. The piston rod end of the lifting cylinder 642 penetrates the sliding frame 641 and is connected to a clamping cylinder 643. The sliding frame 641 on the grasping mechanism 64 serves as the connection main body of the grasping mechanism 64. When the electric slide rail 62 and the electric slide rail 63 drive the corresponding grasping mechanism 64 to move, the corresponding sliding frame 641 moves synchronously. When the sliding frame 641 moves, it drives the lifting cylinder 642 and the clamping cylinder 643 to move, so that the clamping cylinder 643 can be adjusted to the position where the alloy wire needs to be clamped. After moving in place, the lifting cylinder 642 pushes the clamping cylinder 643 downward to the outer wall position of the alloy wire. When the clamping cylinder 643 operates, it can clamp the alloy wire. After the alloy wire is clamped, through the overall movement of the grasping mechanism 64, the alloy wire is tractionally pulled. When the alloy wire is pulled in place, the intercepting assembly 3 moves to track and cut the alloy wire. After the cutting is completed, the cut alloy wire is pushed forward a certain distance by the intercepting assembly 3. Then the grasping mechanism 64 pulls the alloy wire forward, causing the alloy wire to move away from between the first guiding wheel 53 and the second guiding wheel 54. At the same time, the grasping mechanism 64 releases the alloy wire. Then, by swinging and tilting the blanking plate 42, the alloy wire can be discharged by blanking.

[0074] When a wire is conveyed forward by the intercepting assembly 3 and the cutting is completed, and the next wire has been conveyed forward. At this time, the grasping mechanism 64 holding the cut alloy wire is discharging materials and cannot be reset and clamp the conveyed alloy wire in a short time. In this state, the alloy wire has sagged after passing through the first guiding wheel 53 and the second guiding wheel 54, and the grasping mechanism 64 cannot obtain it.

[0075] To this end, the straightened alloy wire passes through the intercepting component 3 and is guided and transported by the first guide wheel 53 and the second guide wheel 54. The alloy wire reaches the top position of the dumping plate 42. At this time, the grabbing mechanism 64 at the bottom of the electric slide rail 62 clamps the alloy wire. Then the alloy wire is moved and pulled by the grabbing mechanism 64 on the electric slide rail 62. When the alloy wire is pulled, the grabbing mechanism 64 on the electric slide rail 63 is in a standby position on one side of the guide component 5. After the alloy wire is pulled to a certain length, the guide cylinder 52 pulls the first guide wheel 53 away from the second guide wheel 54, and the alloy wire is no longer guided.

[0076] Then, the adjusting cylinder 38 pushes the carrying plate 31 to move, and the moving speed is the same as the conveying speed of the alloy wire. Then, the vertical cylinder 32 pushes the push plate 33 upward, causing the guide column 37 to slide inside the corresponding slide groove 34, and the cutting knife 36 corresponding to the guide column 37 slides on the side wall of the guide rail 35 under the guidance of the slide groove 34, causing the two cutting knives 36 to approach each other to cut the alloy wire. While the alloy wire is cut, the adjusting cylinder 38 accelerates the speed of pushing the carrying plate 31 to move, and the moving speed is greater than the speed of the alloy wire. The conveying speed, at the same time, the grabbing mechanism 64 for pulling the alloy wire accelerates and maintains the same moving speed as the carrying plate 31, and the cut alloy wire quickly moves forward a distance. When the alloy wire moves out from between the first guide wheel 53 and the second guide wheel 54, the grabbing mechanism 64 releases the clamped alloy wire, and the cut alloy wire falls onto the surface of the pouring plate 42, and then the pouring cylinder 41 drives the pouring plate 42 to swing, thereby guiding the alloy wire to be discharged, and then the pouring plate 42 returns to a horizontal state for standby use.

[0077] In embodiment three, the mobile intercepting component 3 still needs to push one end of the wire forward. The speed of this movement will be greater than the normal conveying speed of the wire. The purpose is to pull the two ends of the wire apart, but the end that is actively conveyed forward will form a secondary extrusion force between the guide component 5. If the first guide wheel 53 and the second guide wheel 54 are controlled to separate and then pushed forward, the alloy wire will slip out of the guide component 5 and sag. Once it sags, the alloy wire will slide out from the position of the intercepting component 3. In this state, the intercepting component 3 cannot push the cut alloy wire to move and separate from the conveyed alloy wire.

[0078] To this end, a ring body 55 is connected to the bottom of the first guide wheel 53, and a spool 56 is installed at the bottom of the second guide wheel 54. The outer wall of the ring body 55 is inserted into the inside of the spool 56. A first inclined portion 57 is provided at the top edge position of the spool 56. When the first guide wheel 53 and the second guide wheel 54 are separated, the cooperation of the ring body 55 and the spool 56 is used to keep the alloy wire still in the position between the first guide wheel 53 and the second guide wheel 54 without falling. This not only prevents the alloy wire from sagging, but also allows the cutting assembly 3 to push the cut alloy wire to move and separate from the conveyed alloy wire.

[0079] When the alloy wire is being pulled, the end of the alloy wire still slides and rubs on the top of the blanking plate 42, and there is still a risk of the end of the alloy wire bending.

[0080] To this end, clamping plates 644 are connected to both output ends of the clamping cylinder 643. Two sets of clamping and warping mechanisms 645 are installed between the corresponding clamping plates 644. The clamping and warping mechanism 645 includes a first hinge seat 6451 installed on the side wall of the corresponding clamping plate 644 and a limiting groove 6452 opened on the side wall of the first hinge seat 6451. A sliding rod 6453 penetrates through the inside of the limiting groove 6452. A spring 6456 is connected between the outer side wall of the sliding rod 6453 and the inner wall of the limiting groove 6452. A second hinge seat 6454 is connected to the outer side wall of the sliding rod 6453. A rubber clamping block 6455 is hinged inside the second hinge seat 6454. A support rod 6457 is horizontally connected inside the first hinge seat 6451. The support rod 6457 is in contact with the bottom of the second hinge seat 6454. An arc groove is opened on the side of the rubber clamping block 6455 away from the second hinge seat 6454. A scraping portion 6458 is opened at the bottom of the arc groove. A second inclined portion 6459 is provided at the inner wall position of the first hinge seat 6451. An adaptation chamfer is opened at the top of the second hinge seat 6454 away from the rubber clamping block 6455. The adaptation chamfer is adapted to the second inclined portion 6459.

[0081] Specifically, the gripping mechanism 64 at the bottom of the electric slide rail 62 clamps the alloy wire. Correspondingly, the piston rod of the lifting cylinder 642 extends and drives the clamping cylinder 643 and the clamping plate 644 to move downward. The clamping and warping mechanism 645 on this clamping plate 644 fits against the top surface of the blanking plate 42. Then, the clamping cylinder 643 drives the two clamping plates 644 to approach each other, and the two sets of clamping and warping mechanisms 645 approach each other. The rubber clamping blocks 6455 in the clamping and warping mechanism 645 slide on the top of the blanking plate 42. During the sliding process, the scraping part 6458 on the rubber clamping block 6455 shovels up the alloy wire that fits against the top of the blanking plate 42. Then, the two rubber clamping blocks 6455 continue to approach each other and clamp the alloy wire. When the alloy wire is clamped, the two rubber clamping blocks 6455 continue to approach and squeeze. At this time, the first hinge seat 6451 squeezes the second hinge seat 6454, and the sliding rod 6453 slides reversely inside the limit groove 6452 and compresses the spring 6456. At this time, the first hinge seat 6451 approaches the second hinge seat 6454. The matching chamfer on the side wall of the second hinge seat 6454 slides on the surface of the second inclined part 6459 corresponding to the first hinge seat 6451. And the second hinge seat 6454 undergoes an upward tilting movement under the influence of the inclination angle of the second inclined part 6459. At this time, the clamped alloy wire is lifted up by a certain height. Subsequently, the electric slide rail 62 drives the gripping mechanism 64 and the clamped alloy wire to be conveyed forward and pulled. Since the alloy wire is lifted up by a certain height, the end of the alloy wire is separated from the top of the blanking plate 42. Furthermore, the situation where the alloy wire is rubbed and bent will not occur.

[0082] Embodiment 4, a working method for straightening and cutting an alloy wire, uses an alloy wire straightening and cutting device as described above, including the following steps:

[0083] S1. Pass the unrolled alloy wire through the straightening component 2, the intercepting component 3, and the guiding component 5 in sequence, and use the straightening component 2 to straighten the alloy wire.

[0084] The more specific steps of S1 are:

[0085] S11. Pass the unrolled alloy wire through between the first straightening wheel 213 and the first auxiliary wheel 214 for horizontal straightening, and then pass through between the second straightening wheel 222 and the second auxiliary wheel 224 for vertical straightening. The straightened alloy wire passes through the guiding groove 25 and between the two driving wheels 24. At this time, the driving motor 23 drives one of the driving wheels 24 to rotate, and the two driving wheels 24 rotate towards each other through the extrusion and frictional force on the alloy wire, thereby assisting in conveying the alloy wire.

[0086] S12. The alloy wire passes through the guiding groove 25 and the two driving wheels 24, then passes under the bottom of the pushing plate 33, between the two cutting knives 36, and between the first guiding wheel 53 and the second guiding wheel 54, and continues to be conveyed forward.

[0087] S2. The straightened alloy wire passes through the intercepting assembly 3 and is guided and conveyed by the guiding assembly 5. Then, it is assisted in traction by the grasping mechanism 64 on the electric slide rail 1 62, and the grasping mechanism 64 on the electric slide rail 2 63 is in standby. When the alloy wire is pulled to an appropriate length, the guiding assembly 5 cancels the guiding and conveying of the alloy wire, and uses the intercepting assembly 3 to move and track, and assist in cutting the alloy wire. The cut alloy wire falls onto the surface of the discharging plate 42. Then, the discharging cylinder 41 drives the discharging plate 42 to swing, thereby guiding and discharging the alloy wire. After that, the discharging plate 42 returns to the horizontal state and is in standby again.

[0088] The more specific steps of S2 are as follows:

[0089] S21. The straightened alloy wire passes through the intercepting assembly 3 and is guided and conveyed by the first guiding wheel 53 and the second guiding wheel 54. The alloy wire reaches the top position of the discharging plate 42. At this time, the grasping mechanism 64 at the bottom of the electric slide rail 1 62 clamps the alloy wire, that is, the piston rod of the corresponding lifting cylinder 642 extends and drives the clamping cylinder 643 and the clamping plate 644 to move downward. The clamping and warping mechanism 645 on this clamping plate 644 fits with the top surface of the discharging plate 42. Then, the clamping cylinder 643 drives the two clamping plates 644 to approach each other, and the two clamping and warping mechanisms 645 approach each other. The rubber clamping block 6455 in the clamping and warping mechanism 645 slides on the top of the discharging plate 42. During the sliding process, the scraping part 6458 on the rubber clamping block 6455 shovels up the alloy wire attached to the top of the discharging plate 42. Then, the two rubber clamping blocks 6455 continue to approach each other and clamp the alloy wire.

[0090] S22. When the alloy wire is clamped, the two rubber clamping blocks 6455 continue to approach and squeeze. At this time, the first hinge seat 6451 squeezes the second hinge seat 6454, and the sliding rod 6453 slides reversely inside the limiting groove 6452 and compresses the spring 6456. At this time, the first hinge seat 6451 approaches the second hinge seat 6454. The matching chamfer on the side wall of the second hinge seat 6454 slides on the surface of the second inclined part 6459 on the corresponding first hinge seat 6451. And the second hinge seat 6454 moves upward and obliquely under the influence of the inclination angle of the second inclined part 6459. At this time, the clamped alloy wire is lifted upward by a certain height. Subsequently, the electric slide rail 1 62 drives the grasping mechanism 64 and the clamped alloy wire to be conveyed forward and traction.

[0091] S23. When the alloy wire is pulled, the grabbing mechanism 64 on the electric slide rail 63 is on standby at one side of the guide assembly 5. After the alloy wire is pulled to a certain length, the guide cylinder 52 pulls the first guide wheel 53 away from the second guide wheel 54. The alloy wire is no longer guided, but the ring body 55 and the I-shaped wheel 56 cooperate to keep the alloy wire between the first guide wheel 53 and the second guide wheel 54.

[0092] S24, then the cylinder 38 is adjusted to push the carrier plate 31 to move, and the moving speed is the same as the conveying speed of the alloy wire. Then the vertical cylinder 32 pushes the push plate 33 to move upward, causing the guide column 37 to slide inside the corresponding slide groove 34, and the cutting knife 36 corresponding to the guide column 37 slides on the side wall of the guide rail 35 under the guidance of the slide groove 34, causing the two cutting knives 36 to approach each other to cut the alloy wire. While the alloy wire is cut, the cylinder 38 is adjusted to speed up the speed of pushing the carrier plate 31 to move, and the moving speed is greater than the alloy wire. The conveying speed of the wire, at the same time, the moving speed of the grabbing mechanism 64 for pulling the alloy wire is accelerated and maintained at the same speed as the moving speed of the supporting plate 31, and the cut alloy wire quickly moves forward a distance, and when the alloy wire moves out from between the first guide wheel 53 and the second guide wheel 54, the grabbing mechanism 64 releases the clamped alloy wire, and the cut alloy wire falls onto the surface of the dumping plate 42, and then the dumping cylinder 41 drives the dumping plate 42 to swing, thereby guiding the alloy wire to be discharged, and then the dumping plate 42 returns to a horizontal state for standby use.

[0093] S3. After the alloy wire is cut off, the straightened alloy wire continues to pass through the inside of the guide assembly 5. The guide assembly 5 re-clamps and guides the alloy wire that continues to be transported. The grabbing mechanism 64 on the electric slide rail 2 63 clamps and pulls the alloy wire, and cuts and unloads the material according to the above steps. At the same time, the electric slide rail 1 62 drives the grabbing mechanism 64 to swing away from the alloy wire conveying direction. At the same time, the grabbing mechanism 64 corresponding to the electric slide rail 1 62 moves toward the direction close to the guide assembly 5. After moving into place, the electric slide rail 1 62 is straightened, and the corresponding grabbing mechanism 64 is reset to the waiting position to wait for the next traction operation.

[0094] The more specific steps of S3 are:

[0095] S31. After the alloy wire is cut off, the straightened alloy wire continues to pass through the first guide wheel 53 and the second guide wheel 54. The first guide wheel 53 and the second guide wheel 54 approach each other to clamp, guide and convey the alloy wire that continues to be conveyed. The grabbing mechanism 64 on the electric slide rail 2 63 clamps and pulls the alloy wire, and cuts and unloads the material according to the above steps. At the same time, the electric slide rail 1 62 drives the grabbing mechanism 64 to swing away from the conveying direction of the alloy wire. At the same time, the grabbing mechanism 64 corresponding to the electric slide rail 1 62 moves toward the direction close to the guide assembly 5. After moving into place, the electric slide rail 1 62 is straightened and reset, and the corresponding grabbing mechanism 64 is reset to the waiting position to wait for the next traction operation.

[0096] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
