After the head processing is completed, the speed reducer motor is started to drive the conveying gear to rotate, thereby driving the conveying chain to move, and the titanium rod is pulled into and out of the cold drawing die from one end.

[0018] ‌Step 2: After the titanium rod is pulled out, the traction driving device pushes the displacement plate to move along the moving frame, the displacement plate drives the clamping block to contact and extrude the inclined block, the clamping block is rotated through the extrusion of the inclined surface, the gap is reduced to clamp the titanium rod, at the same time, the clamping block drives the pressure plate to rotate, the tension spring is stretched, and the sliding block slides in the displacement plate.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] The cold drawing machine for processing TA titanium bars and its usage method involve using a contact rod to compress the contact rod and the contact clamping block, forcing them to rotate within the inner wall of the clamping block. As the contact clamping block rotates, it compresses and pushes the titanium bar it holds, causing the end of the titanium bar to extend. The continuous pulling of the rubber wheel causes one end of the titanium bar to insert from the inner wall of the guide hole into the inner wall of the correction component. This overcomes the shortcomings of existing cold drawing equipment, where residual stress inside the metal bar causes bending when the stress is redistributed after cold drawing. This necessitates unified transportation and straightening of the metal bars using a straightening machine after cold drawing, resulting in a cumbersome titanium bar processing process, low processing efficiency, and inconvenient transportation of the titanium bars after cold drawing.

Therefore, they should not be construed as limitations on this invention.

[0037] like Figures 1-10As shown, a cold drawing machine for processing TA29 titanium bars and its method of use include a movable frame 1 and a cold drawing die 101. The cold drawing die 101 is fixedly installed on the top surface of the movable frame 1. A movable wheel 102 is slidably contacted on the top surface of the movable frame 1. A displacement plate 103 is rotatably installed on one side surface of the movable wheel 102. A clamping block 104 is slidably and rotatably installed on the bottom surface of the displacement plate 103. A contact tilting block 105 is provided on the bottom surface of the clamping block 104. A contact clamping block 106 is rotatably installed on the inner wall of the clamping block 104. A contact rod 107 is fixedly installed on the top surface of the contact clamping block 106. The cold drawing die 101 is located on one side... A pressing inclined block 108 is fixedly installed on the surface. A trigger component is installed on the bottom surface of the displacement plate 103. A conveying mechanism is installed on the top surface of the moving wheel 102. A feeding component is installed on the top surface of the moving frame 1. The moving wheel 102 consists of four moving wheels that are linearly arrayed and equidistantly distributed on one side surface of the displacement plate 103. The clamping block 104 consists of two clamping blocks that are equidistantly distributed on the bottom surface of the displacement plate 103. The two clamping blocks 104 are rotatably connected to the displacement plate 103 through a rotating shaft 201. Each clamping block 104 has a corresponding contact inclined block 105 on its bottom surface and a corresponding contact clamping block 106 distributed on the inner wall of each clamping block 104.

[0038] In this embodiment of the invention, when the displacement plate 103 is moving, the contact inclined block 105 provided on the bottom surface of the clamping block 104 will come into contact with the extrusion inclined block 108 installed on one side surface of the cold drawing die 101. Since one side surface of the contact inclined block 105 is provided with an inclined surface, when the contact inclined block 105 and the extrusion inclined block 108 come into contact with each other, extrusion will occur between the two. At this time, the clamping block 104 under extrusion will rotate on the bottom surface of the displacement plate 103. The clamping block 104 is movably rotatably connected to the pressure plate 2. When the clamping block 104 rotates slightly due to contact extrusion, the gap between the two clamping blocks 104 will become smaller, thereby realizing the clamping of the titanium rod by the clamping block 104.

[0039] Reference Figures 1-10Specifically, the triggering component includes pressure plates 2, of which there are two. One end of each pressure plate 2 is connected to one end of each clamping block 104 via two rotating shafts 201. The inner wall of the pressure plate 2 is fitted with a rotating shaft 201, which is slidably connected to the inner wall of the displacement plate 103. The other end of each pressure plate 2 is connected to a slider 205 via a rotating shaft 201. A spring 202 is fitted on the outer surface of the rotating shaft 201. A limiting plate 204 is fitted on the bottom surface of the displacement plate 103. A slider 205 is slidably fitted on the inner wall of the displacement plate 103. A lever 206 is rotatably fitted on the inner wall of the slider 205. A limiting protrusion 207 is provided on the bottom surface of the lever 206. One side surface of the limiting protrusion 207 is in contact with the top surface of the limiting plate 204. A reset post 203 is fitted on one side surface of the lever 206.

[0040] In this embodiment of the invention, the clamping block 104 drives the pressure plate 2 to rotate synchronously during rotation. Since they form an X-shaped connection, the distance between the clamping block 104 and the pressure plate 2 gradually increases as they rotate. At this time, the spring 202 mounted on the outer surface of the rotating shaft 201 is stretched due to the increased distance. Furthermore, since one end of the pressure plate 2 is connected to the slider 205, when the clamping block 104 and the pressure plate 2 rotate, the slider 205 slides on the inner wall of the displacement plate 103, causing displacement of the slider 205. A lever 206 is mounted on the inner wall of the slider 205, and the lever 206 moves along with the slider 205. When the slider 205 moves... The limiting protrusion 207 on the bottom surface of the lever 206 will no longer contact the limiting plate 204 installed on the bottom surface of the displacement plate 103 due to the movement, so that the limiting plate 204 no longer supports the lever 206. At this time, due to the loss of support, the lever 206 will rotate on the inner wall of the slider 205 due to gravity. At this time, the lever 206 will rotate downward due to gravity. One end of the downward rotating lever 206 will contact the conveyor gear 3 of the conveyor chain 301, so that one end of the lever 206 hooks the conveyor gear 3 of the conveyor chain 301. When the two are fixed together, the rotating conveyor chain 301 will pull the pressure plate 2 to move through the lever 206.

[0041] The conveying mechanism includes a drive assembly and a straightening assembly. The drive assembly includes a conveying gear 3, which is rotatably mounted on the inner wall of the movable frame 1. A conveying chain 301 is driven and meshed with the conveying gear 3 on the outer surface of the conveying gear 3. The outer surface of the conveying chain 301 and the conveying gear 3 are in active contact with the bottom surface of the lever 206. There are two conveying gears 3 evenly distributed on the inner wall of the movable frame 1. A reduction motor 302 is mounted on one side surface of the conveying gear 3. A trigger rod 303 is mounted on one side surface of the movable frame 1. There are two trigger rods 303 evenly distributed on one side and the other side surface of the movable frame 1. The trigger rods 303 are in active contact with the contact rod 107. A reset contact block 304 is fixedly mounted on the inner wall of the movable frame 1. The reset column 203 is in active contact with the reset contact block 304.

[0042] The straightening assembly includes a housing 4, which is fixedly mounted on one side surface of the movable frame 1. A contact rubber shaft 401 is mounted on the inner wall of the housing 4. A transmission gear 402 is mounted on the outer surface of both the contact rubber shaft 401 and the conveying gear 3. A synchronous gear 403 is mounted on the outer surface of the contact rubber shaft 401. A transmission chain 404 meshes with the outer surface of the transmission gear 402. A straightening wheel 405 is rotatably mounted on the inner wall of the housing 4. A guide hole 406 is provided on one side surface of the housing 4. There are two contact rubber shafts 401 that are equidistantly distributed on the inner wall of the housing 4. The outer surfaces of the two contact rubber shafts 401 are correspondingly distributed with synchronous gears 403. The two contact rubber shafts 401 are connected to each other through synchronous gears 403. There are several straightening wheels 405 that are equidistantly distributed in a linear array on the inner wall of the housing 4.

[0043] The feeding assembly includes a bracket 5, which is fixedly installed on one side surface of the movable frame 1. A drive motor 501 is installed on the top surface of the bracket 5, and a transmission shaft 502 is installed on the bottom surface of the drive motor 501. The output end of the drive motor 501 is fixedly connected to one end of one of the transmission shafts 502. Meshing gears 504 are distributed on the outer surfaces of the two transmission shafts 502. The transmission shafts 502 are two equidistantly distributed on the top surface of the bracket 5. Rubber wheels 503 are installed on the outer surfaces of the transmission shafts 502. Each transmission shaft 502 has rubber wheels 503 distributed on its outer surface. Meshing gears 504 are installed on the outer surface of the rotating shaft 201. The two meshing gears 504 mesh with each other for transmission.

[0044] The operating method of the cold drawing machine includes the following steps:

[0045] Step 1: Before the cold drawing operation, the titanium rod to be cold drawn is first headed to reduce the diameter of one end of the titanium rod so that it can pass through the inner wall of the cold drawing mold 101. When the heading is completed, the reduction motor 302 is started. When the reduction motor 302 is started, it will drive the conveying gear 3 connected to the output end to rotate. The conveying gear 3 drives the conveying chain 301 to move, so that the titanium rod to be cold drawn passes through the inner wall of the cold drawing mold 101 and passes through the other side surface of the cold drawing mold 101.

[0046] Step 2: When the titanium rod is completely passed through, the displacement plate 103 is moved on the surface of the moving frame 1 using the existing traction drive device. The displacement plate 103 moves along the moving frame 1 to one side surface of the cold drawing die 101. When the displacement plate 103 is moving, the contact inclined block 105 provided on the bottom surface of the clamping block 104 will come into contact with the extrusion inclined block 108 installed on one side surface of the cold drawing die 101. Since the one side surface of the contact inclined block 105 is provided with an inclined surface, when the contact inclined block 105 and the extrusion inclined block 108 come into contact with each other, extrusion will occur between the two. At this time, the clamping block 104 under extrusion will rotate on the bottom surface of the displacement plate 103. The clamping block 104 is movably rotatably connected to the pressure plate 2. When the clamping block 104 rotates slightly due to contact extrusion, the gap between the two clamping blocks 104 will become smaller, thereby realizing the clamping of the titanium rod by the clamping block 104.

[0047] Step 3: When the slider 205 moves, the limiting protrusion 207 on the bottom surface of the lever 206 will no longer contact the limiting plate 204 installed on the bottom surface of the displacement plate 103 due to the movement. This causes the limiting plate 204 to no longer support the lever 206. At this point, due to the loss of support, the lever 206 will rotate on the inner wall of the slider 205 due to gravity. The lever 206 will then rotate downwards due to gravity, and one end of the downward-rotating lever 206 will contact the conveyor gear 3 of the conveyor chain 301. This causes one end of the lever 206 to hook onto the conveyor gear 3 of the conveyor chain 301. When the two interact... When the phase is fixed, the rotating conveyor chain 301 and the conveyor gear 3 will pull the pressure plate 2 to move through the lever 206. When the pressure plate 2 rotates, it will drive the clamping block 104 to rotate synchronously, so that the two clamping blocks 104 can forcefully clamp the titanium rod. As the conveyor chain 301 moves continuously, the conveyor chain 301 and the conveyor gear 3 will pull the entire displacement plate 103 along the surface of the moving frame 1 through the lever 206. And because the clamping block 104 clamps the titanium rod, the displacement plate 103 will achieve the function of cold drawing the titanium rod through the clamping block 104 during the movement.

[0048] Step 4: When the cold drawing operation is completed, the titanium rod is completely pulled out from the inner wall of the cold drawing mold 101. At this time, as the displacement plate 103 moves continuously, one side surface of the contact rod 107 will come into contact with one side surface of the trigger rod 303. Since the trigger rod 303 is in a stationary state while the contact rod 107 is in a moving state, when the two come into contact, the trigger rod 303 will squeeze the contact rod 107, forcing the contact rod 107 and the contact clamping block 106 to rotate 135 degrees on the inner wall of the clamping block 104. When the contact clamping block 106 rotates, it will push the titanium rod it is holding to move by squeezing, so that the end of the titanium rod extends out.

[0049] Step 5: When the titanium rod is inserted into the inner wall of the outer casing 4, it will be inserted between the two contact rubber shafts 401. The contact rubber shafts 401 are connected to each other through the transmission gear 402, the transmission chain 404 and the conveying gear 3. So at this time, the contact rubber shafts 401 will be driven to rotate on the inner wall of the outer casing 4. The rotating contact rubber shafts 401 will push the titanium rod between the straightening wheels 405 through rotation. The straightening wheels 405 will be used to straighten the cold-drawn metal plate.

[0050] Specific operating procedure: Before cold drawing, the titanium rod to be cold drawn is first headed, reducing the diameter of one end so that it can pass through the inner wall of the cold drawing mold 101. When the heading is completed, the reduction motor 302 is started. When the reduction motor 302 starts, it drives the conveyor gear 3 connected to the output end to rotate. The conveyor gear 3 drives the conveyor chain 301 to move, so that the titanium rod to be cold drawn passes through the inner wall of the cold drawing mold 101 and exits from the other side surface of the cold drawing mold 101. When the titanium rod has completely passed through, the displacement plate 103 is driven to move on the surface of the moving frame 1 using a traction drive device of existing technology, so that the displacement plate 103 moves along the moving frame 1 to the cold drawing mold. On one side surface of the clamping block 104, when the displacement plate 103 moves, the contact inclined block 105 on the bottom surface of the clamping block 104 will come into contact with the extrusion inclined block 108 installed on one side surface of the cold drawing die 101. Since one side surface of the contact inclined block 105 is inclined, when the contact inclined block 105 and the extrusion inclined block 108 come into contact, extrusion will occur between them. At this time, the clamping block 104 under extrusion will rotate on the bottom surface of the displacement plate 103. The clamping block 104 is rotatably connected to the pressure plate 2. When the clamping block 104 rotates slightly due to contact extrusion, the gap between the two clamping blocks 104 will decrease, thereby achieving the clamping of the titanium rod by the clamping block 104. The clamping block 104 rotates... During the process, the pressure plate 2 will rotate synchronously. Since the two form an X-shaped connection, the distance between the clamping block 104 and the pressure plate 2 will gradually increase when they rotate. At this time, the spring 202 installed on the outer surface of the rotating shaft 201 will be stretched due to the increase in distance. Since one end of the pressure plate 2 is connected to the slider 205, when the clamping block 104 and the pressure plate 2 rotate, the slider 205 will slide on the inner wall of the displacement plate 103, thereby causing the slider 205 to move. The inner wall of the slider 205 is equipped with a lever 206. At this time, the lever 206 will move along with the slider 205. When the slider 205 moves, the limiting protrusion 207 set on the bottom surface of the lever 206 will be stretched due to the change in distance. The sliding block 206 no longer contacts the limiting plate 204 mounted on the bottom surface of the displacement plate 103, thus the limiting plate 204 no longer supports the lever 206. Due to the loss of support, the lever 206 rotates on the inner wall of the slider 205 due to gravity. The lever 206 then rotates downwards due to gravity, and one end of the downward-rotating lever 206 contacts the conveyor gear 3 of the conveyor chain 301. This hooks the conveyor gear 3 of the conveyor chain 301, and when the two are fixed together, the rotating conveyor gear 3 of the conveyor chain 301 pulls the pressure plate 2 through the lever 206, causing it to move. The rotation of the pressure plate 2 synchronously drives the clamping block 104 to rotate as well.This allows the two clamping blocks 104 to forcefully clamp the titanium rod. As the conveyor chain 301 moves continuously, the conveyor gear 3 of the conveyor chain 301 pulls the entire displacement plate 103 along the surface of the moving frame 1 via the lever 206. Furthermore, because the clamping blocks 104 are clamping the titanium rod, the displacement plate 103 achieves a cold-drawing function on the titanium rod during its movement.

[0051] When the cold drawing operation is completed, the titanium rod is completely pulled out from the inner wall of the cold drawing mold 101. As the displacement plate 103 continues to move, one side of the contact rod 107 will come into contact with one side of the trigger rod 303. Since the trigger rod 303 is stationary while the contact rod 107 is moving, when they come into contact, the trigger rod 303 will press against the contact rod 107, forcing the contact rod 107 and the contact clamping block 106 to rotate 135 degrees within the inner wall of the clamping block 104. As the contact clamping block 106 rotates, it will push against the contact rod. The titanium rod held by the lever is moved, causing its end to extend. When the displacement plate 103 moves along the moving frame 1 to its end, the reset post 203 mounted on the top surface of the lever 206 will come into contact with the reset contact block 304. Since the reset contact block 304 has a certain inclination angle, when the two come into contact, the reset post 203 will slide along the inclination surface of the reset contact block 304, thereby forcing the lever 206 to rotate on the inner wall of the slider 205. When the lever 206 rotates, its end will be displaced from the conveyor chain 301 due to rotation. The surface of the conveying gear 3 detaches, causing the conveying chain 301 to stop moving the displacement plate 103. Simultaneously, as the lever 206 detaches from the surface of the conveying chain, the stretched spring 202 quickly retracts, pulling the slider 205 along the inner wall of the displacement plate 103 via the rotating shaft 201. At this time, the lever 206 retracts along with the slider 205. During the retraction process, the bottom of the lever 206 contacts the top surface of the limiting plate 204. As the lever 206 continues to retract... The contact point between the two will form a lever point, causing the contact rod 107 to rotate and reset to a near-horizontal angle. At the same time, the pressure plate 2 resets, causing the X-shaped clamping block 104 to open and no longer clamp the titanium rod. Simultaneously, the extended titanium rod will be inserted between the two rubber wheels 503. Since the titanium rod has been headed, its end has a smaller diameter. Therefore, the two rubber wheels 503 in contact with the titanium rod will rotate and pull the titanium rod to move. Through the continuous pulling of the rubber wheels 503, one end of the titanium rod is inserted from the inner wall of the guide hole 406 into the inner wall of the correction component.

[0052] When the titanium rod is inserted into the inner wall of the outer casing 4, it will be inserted between the two contact rubber shafts 401. The contact rubber shafts 401 are connected to each other through the transmission gear 402, the transmission chain 404 and the conveying gear 3. So at this time, the contact rubber shafts 401 will be driven to rotate on the inner wall of the outer casing 4. The rotating contact rubber shafts 401 will push the titanium rod between the straightening wheels 405 through rotation. The straightening wheels 405 will be used to straighten the cold-drawn metal plate.

[0053] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
