In the embodiment of the application, when the displacement plate 103 moves, the contact inclined block 105 provided on the bottom end surface of the clamping block 104 is in contact with the extrusion inclined block 108 fixedly 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 are in contact with each other, extrusion is generated between the two, at this time, the clamping block 104 subjected to the extrusion is rotated on the bottom end surface of the displacement plate 103, the clamping block 104 and the pressure plate 2 are rotatably connected, when the clamping block 104 is slightly rotated due to contact extrusion, the gap between the two clamping blocks 104 is reduced, thereby realizing clamping of the titanium rod by the clamping block 104.

[0023] Referring to Figures 1-10 Specifically, the trigger assembly includes two pressure plates 2, one end of the two pressure plates 2 is connected with one end of the two clamping blocks 104 through two rotating shafts 201 respectively, the inner wall of the pressure plate 2 is installed with a rotating shaft 201, the rotating shaft 201 is slidably connected with the inner wall of the displacement plate 103, the other end of the two pressure plates 2 is connected with a sliding block 205 through a rotating shaft 201, the outer side surface of the rotating shaft 201 is installed with a spring 202, the bottom end surface of the displacement plate 103 is installed with a limiting plate 204, the inner wall of the displacement plate 103 is slidably installed with the sliding block 205, the inner wall of the sliding block 205 is rotatably installed with a leverage 206, the bottom end surface of the leverage 206 is provided with a limiting protrusion 207, one side surface of the limiting protrusion 207 is in movable contact with the top end surface of the limiting plate 204, and one side surface of the leverage 206 is installed with a reset column 203.

[0024] In the embodiment of the application, the clamping block 104 drives the pressure plate 2 to rotate synchronously during rotation. Since the two are connected in X shape, the distance between the clamping block 104 and the pressure plate 2 gradually increases when the two rotate. At this time, the spring 202 installed on the outer surface of the rotating shaft 201 is stretched due to the increase in distance. Since one end of the pressure plate 2 is connected to the sliding block 205, when the clamping block 104 and the pressure plate 2 rotate, the sliding block 205 slides on the inner wall of the displacement plate 103, so that the sliding block 205 is displaced. The inner wall of the sliding block 205 is provided with a leverage 206. At this time, the leverage 206 moves together with the sliding block 205. When the sliding block 205 moves, the limiting protrusion 207 provided on the bottom end surface of the leverage 206 is no longer in contact with the limiting plate 204 provided on the bottom end surface of the displacement plate 103, so that the limiting plate 204 no longer supports the leverage 206. At this time, the leverage 206 rotates on the inner wall of the sliding block 205 due to gravity. At this time, the leverage 206 rotates downward due to gravity. At this time, one end of the leverage 206 in contact with the conveying gear 3 of the conveying chain 301. When the two are fixed to each other, the conveying gear 3 of the conveying chain 301 moves by the leverage 206 to pull the pressure plate 2.

The driving assembly comprises the conveying gear 3, which is rotatably installed on the inner wall of the moving frame 1.

One side surface of the moving frame 1 is provided with a trigger lever 303. The trigger lever 303 is two equidistantly distributed on one side and the other side surface of the moving frame 1. The trigger lever 303 is in movable contact with the contact lever 107. The moving frame 1 is fixedly provided with a reset contact block 304. The reset column 203 is in movable contact with the reset contact block 304.

[0026] The straightening assembly comprises a shell 4 fixedly installed on one side surface of the moving frame 1, the inner wall of the shell 4 is provided with a contact rubber shaft 401, the contact rubber shaft 401 and the outer side surface of the conveying gear 3 are provided with a transmission gear 402, the outer side surface of the contact rubber shaft 401 is provided with a synchronous gear 403, the outer side surface of the transmission gear 402 is engaged with a transmission chain 404, the inner wall of the shell 4 is rotatably provided with a straightening wheel 405, one side surface of the shell 4 is provided with a guide hole 406, the contact rubber shaft 401 is equidistantly distributed on the inner wall of the shell 4, the outer side surface of each of the two contact rubber shafts 401 is correspondingly provided with a synchronous gear 403, the two contact rubber shafts 401 are connected with each other through the synchronous gears 403, and the straightening wheel 405 is linearly and equidistantly arranged on the inner wall of the shell 4.

[0027] The feeding assembly comprises a support 5 fixedly installed on one side surface of the moving frame 1, the top end surface of the support 5 is provided with a driving motor 501, the bottom end surface of the driving motor 501 is provided with a transmission shaft 502, the output end of the driving motor 501 is fixedly connected with one end of the transmission shaft 502, the outer side surfaces of the two transmission shafts 502 are correspondingly provided with engagement gears 504, the transmission shafts 502 are equidistantly arranged on the top end surface of the support 5, the outer side surfaces of the transmission shafts 502 are provided with rubber wheels 503, the outer side surfaces of each of the transmission shafts 502 are correspondingly provided with the rubber wheels 503, the outer side surface of the rotating shaft 201 is provided with the engagement gear 504, and the two engagement gears 504 are in engagement transmission with each other.

[0028] The use method of the cold drawing machine comprises the following steps: ‌Step 1: before the cold drawing operation, the titanium rod to be drawn is first subjected to a head processing, so that the diameter of one end of the titanium rod is reduced, and the titanium rod can pass through the inner wall of the cold drawing die 101, when the head processing is completed, the speed reducing motor 302 is started, when the speed reducing motor 302 is started, the conveying gear 3 connected with the output end is driven to rotate, the conveying gear 3 drives the conveying chain 301 to move, and the titanium rod to be drawn is conveyed into the cold drawing die 101 from the inner wall of the cold drawing die 101 and is conveyed out from the other side surface of the cold drawing die 101.

[0029] ‌Step 2: When the titanium rod is completely inserted into the cold-drawing die 101, the displacement plate 103 is driven to move along the surface of the moving frame 1 by the traction drive device of the prior art. When the displacement plate 103 moves, the contact inclined block 105 provided on the bottom surface of the clamping block 104 comes into contact with the extrusion inclined block 108 provided on the side surface of the cold-drawing die 101. Since the side surface of the contact inclined block 105 is provided with an inclined surface, when the contact inclined block 105 comes into contact with the extrusion inclined block 108, extrusion occurs between them. At this time, the clamping block 104 subjected to the extrusion rotates on the bottom surface of the displacement plate 103. The clamping block 104 is rotatably connected with the pressure plate 2. When the clamping block 104 slightly rotates due to the contact extrusion, the gap between the two clamping blocks 104 becomes smaller, thereby achieving the clamping of the titanium rod by the clamping block 104.

[0030] ‌Step 3: When the sliding block 205 moves, the limiting protrusion 207 provided on the bottom surface of the leverage 206 is no longer in contact with the limiting plate 204 provided on the bottom surface of the displacement plate 103, so that the limiting plate 204 no longer supports the leverage 206. At this time, the leverage 206 rotates on the inner wall of the sliding block 205 due to gravity. At this time, the leverage 206 rotates downward due to gravity. The end of the downward rotating leverage 206 comes into contact with the conveying gear 3 of the conveying chain 301, so that the end of the leverage 206 hooks the conveying gear 3 of the conveying chain 301. When they are fixed with each other, the rotating and moving conveying gear 3 of the conveying chain 301 pulls the pressure plate 2 to move through the leverage 206. The pressure plate 2 rotates and synchronously rotates the clamping block 104, so that the two clamping blocks 104 strongly clamp the titanium rod. With the continuous movement of the conveying chain 301, the conveying gear 3 of the conveying chain 301 pulls the entire displacement plate 103 to move along the surface of the moving frame 1 through the leverage 206. Since the clamping block 104 clamps the titanium rod at this time, the displacement plate 103 realizes the cold-drawing function of the titanium rod through the clamping block 104 during the movement.

[0031] ‌Step 4: When the cold-drawing operation is completed, the titanium rod is completely pulled out from the inner wall of the cold-drawing die 101. With the continuous movement of the displacement plate 103, the side surface of the contact lever 107 comes into contact with the side surface of the trigger lever 303. Since the trigger lever 303 is in a stationary state and the contact lever 107 is in a moving state, when they come into contact with each other, the trigger lever 303 extrudes the contact lever 107, forcing the contact lever 107 and the contact clamping block 106 to rotate by 135 degrees on the inner wall of the clamping block 104. When the contact clamping block 106 rotates, it pushes the clamped titanium rod to move through extrusion, so that the end of the titanium rod extends out.

[0032] ‌Step 5: When the titanium rod is inserted into the inner wall of the shell 4, the titanium rod will be inserted between the two contact rubber shafts 401, which are connected to the transmission chain 404 and the transmission gear 402 through the transmission gear 402, and are connected to the conveying gear 3. Therefore, at this time, the contact rubber shaft 401 will be driven to rotate on the inner wall of the shell 4, and the rotating contact rubber shaft 401 will push the titanium rod between the straightening wheels 405, and the straightening wheels 405 will correct the cold-drawn metal plate.

[0033] Specific use process: before the cold drawing operation, first of all, the titanium rod needs to be processed, so that the diameter of the titanium rod is smaller, and the titanium rod can be put out from the inner wall of the cold drawing die 101, when the head is finished, the speed reducer motor 302 is started, when the speed reducer motor 302 is started, the output end connected to the conveying gear 3 will rotate, the conveying gear 3 drives the conveying chain 301 to move, the titanium rod needs to be drawn from the inner wall of the cold drawing die 101, and the titanium rod needs to be drawn from the other side surface of the cold drawing die 101, when the titanium rod is finished, the existing traction drive device is used to drive the displacement plate 103 to move on the surface of the moving frame 1, so that 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 moves, the contact inclined block 105 arranged on the bottom end surface of the clamping block 104 will be in contact with the extrusion inclined block 108 installed on one side surface of the cold drawing die 101, because 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 are in contact with each other, extrusion will occur between them, at this time, the clamping block 104 subjected to extrusion will rotate on the bottom end surface of the displacement plate 103, the clamping block 104 and the pressure plate 2 are movably connected in rotation, when the clamping block 104 rotates slightly due to contact and extrusion, the gap between the two clamping blocks 104 will become smaller, so as to realize the clamping of the clamping block 104 to the titanium rod, and the clamping block 104 will drive the pressure plate 2 to rotate synchronously during rotation, because the X-shaped connection is formed between them, when the clamping block 104 and the pressure plate 2 rotate, the distance between the two will gradually increase, at this time, the spring 202 installed on the outer side surface of the rotating shaft 201 will be stretched due to the increase of the distance, and because one end of the pressure plate 2 is connected with the sliding block 205, when the clamping block 104 and the pressure plate 2 rotate, the sliding block 205 will slide on the inner wall of the displacement plate 103, so as to make the sliding block 205 displace, the inner wall of the sliding block 205 is provided with a leverage 206, at this time, the leverage 206 will displace together with the sliding block 205, when the sliding block 205 displaces, the limiting protrusion 207 arranged on the bottom end surface of the leverage 206 will no longer be in contact with the limiting plate 204 installed on the bottom end surface of the displacement plate 103, so as to make the limiting plate 204 no longer support the leverage 206, at this time, the leverage 206 will rotate on the inner wall of the sliding block 205 due to gravity, at this time, the leverage 206 will rotate downward due to gravity, at this time, the one end of the downward rotating leverage 206 will be in contact with the conveying gear 3 of the conveying chain 301, so as to make one end of the leverage 206 hook the conveying gear 3 of the conveying chain 301, when they are fixed with each other, at this time, the conveying gear 3 of the conveying chain 301 will pull the pressure plate 2 to move through the leverage 206, the pressure plate 2 will drive the clamping block 104 to rotate synchronously when it rotates,Thus, the two clamping blocks 104 firmly clamp the titanium rod. As the conveying chain 301 continuously moves, the conveying gear 3 pulls the entire displacement plate 103 along the surface of the moving frame 1 through the leverage rod 206. Since the clamping blocks 104 are clamping the titanium rod at this time, the displacement plate 103 realizes the cold-drawing function of the titanium rod through the clamping blocks 104 during movement.

[0034] When the cold-drawing operation ends, the titanium rod is completely drawn out of the inner wall of the cold-drawing die 101. As the displacement plate 103 continuously moves, the side surface of the contact rod 107 is in contact with the side surface of the trigger rod 303. Since the trigger rod 303 is in a stationary state and the contact rod 107 is in a moving state, the trigger rod 303 extrudes the contact rod 107 when the two are in contact, forcing the contact rod 107 and the contact clamping block 106 to rotate by 135 degrees in the inner wall of the clamping block 104. When the contact clamping block 106 rotates, it pushes the clamped titanium rod to move, so that the end of the titanium rod extends. When the displacement plate 103 moves to the end of the moving frame 1, the reset column 203 installed on the top surface of the leverage rod 206 is in contact with the reset contact block 304. Since the reset contact block 304 has a certain inclination angle, the reset column 203 slides along the inclined surface of the reset contact block 304 when the two are in contact, thereby forcing the leverage rod 206 to rotate in the inner wall of the sliding block 205. When the leverage rod 206 rotates, its end falls off the surface of the conveying gear 3 of the conveying chain 301 due to the rotational displacement, so that the conveying chain 301 does not move the displacement plate 103. At the same time, since the leverage rod 206 falls off the surface of the conveying chain, the stretched extension spring 202 quickly retracts, pulling the sliding block 205 along the inner wall of the displacement plate 103 through the rotating shaft 201 to reset. At this time, the leverage rod 206 resets together with the sliding block 205. During the resetting of the leverage rod 206, the bottom of the leverage rod 206 is in contact with the top surface of the limiting plate 204. As the leverage rod 206 continuously resets, the contact point between the two forms a lever point, causing the contact rod 107 to continuously rotate and reset to a near horizontal angle. At the same time, the pressure plate 2 resets, causing the X-shaped clamping blocks 104 to open and not clamp the titanium rod. At the same time, the extended titanium rod is inserted between the two rubber wheels 503. Since the titanium rod has been head-treated and its end has a smaller diameter, the two rubber wheels 503 in contact with the titanium rod pull the titanium rod to move through rotation. Through the continuous pulling of the rubber wheels 503, one end of the titanium rod is inserted into the inner wall of the correction assembly from the inner wall of the guide hole 406.

[0035] When the titanium rod is inserted into the inner wall of the shell 4, the titanium rod is inserted between the two contact rubber shafts 401, which are in transmission connection with the transmission chain 404 and the transmission gear 3 through the transmission gear 402, so that the contact rubber shafts 401 are driven to rotate on the inner wall of the shell 4 at this time, and the rotating contact rubber shafts 401 push the titanium rod between the straightening wheels 405, and the straightening wheels 405 correct the cold-drawn metal plate.

[0036] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.

10. A method for using a cold drawing machine, applicable to the cold drawing machine for processing TA29 titanium bars according to claims 1 to 9, characterized in that: The following steps are involved: Step 1: Heading is performed on one end of the titanium rod to reduce its diameter so that it can pass through the inner wall of the cold drawing die (101). After the heading is completed, the reduction motor (302) is started to drive the conveying gear (3) to rotate, thereby driving the conveying chain (301) to move, and the titanium rod is passed through and out of one end of the cold drawing die (101). Step 2: After the titanium rod passes through, the traction drive device pushes the displacement plate (103) to move along the movable frame (1), and the displacement plate (103) drives the clamping block (104) to contact the extrusion inclined block (108). The clamping block (104) rotates through the extrusion of the inclined surface, narrowing the gap to clamp the titanium rod. At the same time, the clamping block (104) drives the pressure plate (2) to rotate, stretching the spring (202), and the slider (205) slides in the displacement plate (103). Step 3: When the slider (205) moves, the lever (206) rotates downward because the limiting protrusion (207) is separated from the limiting plate (204), hooking the conveying chain (301). The conveying chain (301) pulls the pressure plate (2) and the clamping block (104) through the lever (206), strengthens the clamping force, and drags the displacement plate (103) to move along the movable frame (1), thereby realizing the cold drawing of the titanium rod. Step 4: After the cold drawing is completed, the contact rod (107) triggers the trigger rod (303), forcing the contact clamp (106) to rotate and push out the end of the titanium rod. When the displacement plate (103) moves to the end, the reset column (203) contacts the reset contact block (304), driving the lever (206) to separate from the conveyor chain (301), the spring (202) retracts, the clamping block (104) opens, and the titanium rod falls between the rubber wheels (503). Step 5: The rubber wheel (503) rotates and pulls the titanium rod into the guide hole (406), and then inserts it into the housing (4). The contact rubber shaft (401) is driven by the transmission chain (404) to push the titanium rod to the straightening wheel (405) for correction, completing the cold drawing process.
