[0021] The operation method of tungsten-molybdenum wire drawing equipment is as follows:

[0022] S1: When the external equipment drives the tungsten-molybdenum raw material to move, the user controls the driving motor through the device system, and the output gear of the driving motor drives the loading cylinder to rotate on the fixed cylinder through the transmission gear ring, and the inner loading ring inside the loading cylinder 4 drives the corresponding extrusion plate to rotate, so that the inclined surface of the extrusion plate can perform pre-drawing processing on the incoming tungsten-molybdenum rod raw material;

[0023] S2: During this process, the outer ring frame and the inner ring frame installed on the loading cylinder will rotate synchronously. Since the outer force head on the outer ring frame and the inner force head on the inner ring frame are respectively fitted in the corresponding ring grooves, the outer ring frame and the inner ring frame will move back and forth alternately under the action of the ring groove on the fixed cylinder. The outer ring frame and the inner ring frame will drive the corresponding loading box to move synchronously. During this process, the guide groove on the loading box will drive the corresponding horizontal axis to move, and the guide structure composed of the inclined groove and the limit block of the guide groove will drive the corresponding horizontal axis to move downward. The horizontal axis will drive the connecting block and the reset rod to move synchronously through the pressure plate. The reset rod moves in the guide cylinder to further compress the spring, and the connecting block drives the extrusion plate in the initial state to rotate, so that the four extrusion plates squeeze the tungsten-molybdenum rod material while rotating to speed up the wire drawing efficiency;

[0024] S3: When the four extrusion plates in the initial state begin to rotate, the other four extrusion plates that are already at the maximum rotation angle will rotate and reset. In the specific process, when the horizontal axis reaches the vertical groove part of the guide groove, the spring in the guide cylinder will drive the reset rod to move through the reset action, so that the reset rod can drive the corresponding pressure plate to move. In this process, the pressure plate will drive the extrusion plate to rotate and reset away from the tungsten-molybdenum rod raw material through the connecting block. Then the loading box continues to move so that the horizontal axis enters the top of the guide groove. The horizontal axis will first push the trigger member to move. In this process, the trigger member compresses the second spring, and at the same time, the trigger member drives the locking head to move. The locking head will be separated from the positioning hole on the loading box, so that the horizontal axis can drive the limit block to move and compress the first spring. When the horizontal axis passes the limit block and enters the initial position in the guide groove, the first spring will move the limit block to reset, and the second spring will drive the trigger member and the locking head to reset. Through the above operation, the eight extrusion plates are alternately extruded in groups of four;

[0025] S4: The wire drawing raw material processed by the extrusion plate enters the wire drawing mouth formed by the outer die mouth 23 and the inner die mouth 24 through the inner connecting cylinder, so as to be processed and formed. During this process, the rotating loading cylinder will drive the storage cylinder to rotate, and the storage cylinder will drive the first pressure rod and the second pressure rod to rotate. When the second pressure rod is away from the two second arc plates, the second pressure rod no longer applies the closing pressure to the outer die mouth, so that the outer die mouth is no longer worn by wire drawing. At this time, the first pressure rod will fit on the corresponding first arc plate. At this time, the first pressure rod will drive the corresponding inner die mouth to perform the closing operation, so that the inner die mouth can perform the wire drawing operation. The wire drawing operation is performed by alternating the closing of the inner and outer die mouths, thereby effectively improving the service life of the wire drawing die mouth.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the tungsten-molybdenum wire drawing forming equipment and method are provided with eight extrusion structures that can rotate alternately to perform extrusion operations on tungsten-molybdenum materials, thereby accelerating the wire drawing forming efficiency of the materials, and can adapt to materials with larger diameters, and the device can further extend the service life of the die, and the specific contents are as follows:

[0027] 1. Eight extrusion plates with equal angles are rotatably embedded on the inner loading ring, and eight sets of switching mechanisms are slidably embedded on the outer wall of the end of the loading cylinder. The switching mechanism includes a loading box, which is located above the corresponding extrusion plate, and symmetrical guide grooves are provided on both sides of the inner wall of the loading box. The ends of the transverse axis are slidably installed in the guide grooves of the loading box, and the transverse axis is horizontally fixed and penetrates the upper part of the pressure plate. The convex shaft on the top of the connecting block is rotatably installed at the lower end of the pressure plate. The bottom end of the reset rod is coaxially fixedly connected to the top of the pressure plate. The top convex plate of the reset rod is elastically connected to the inner wall of the guide cylinder through a spring. A connecting block is slidably embedded in the sliding groove at the top of the extrusion plate. The loading box drives the transverse axis to move through the guide groove, and the transverse axis will drive the corresponding pressure plate to move. The pressure plate drives the extrusion plate to rotate through the connecting block, and the reset rod will drive the extrusion plate to reset quickly through the reset action of the spring. The eight extrusion plates are alternately extruded and rotated in groups of four;

[0028] 2. The mounting ring is fixedly connected to the inner wall of the fixed cylinder, and the first arc plate and the second arc plate are fixedly connected to the inner wall of the mounting ring with staggered arrangements. The second pressure rod and the first pressure rod are fixedly connected to the outer walls of the outer die opening and the inner die opening, respectively. The convex disk at the end of the second pressure rod is fitted on the corresponding second arc plate, and the convex disk at the end of the first pressure rod is arranged toward the inner wall of the mounting ring, and the convex disk at the end of the first pressure rod is located between the two first arc plates. When the storage cylinder drives the first pressure rod and the second pressure rod to rotate, the first pressure rod will move within the circular trajectory formed by the first arc plate, and the second pressure rod will move within the circular trajectory formed by the second arc plate, so that the outer die opening and the inner die opening can be alternately molded to extend the service life of the die opening.

[0054] S3: When the four extrusion plates 8 in the initial state begin to rotate, the other four extrusion plates 8 that are already at the maximum rotation angle will rotate and reset. In the specific process, when the horizontal axis 11 reaches the vertical groove part of the guide groove 1202, the spring in the guide cylinder 14 will drive the reset rod 13 to move through the reset action, so that the reset rod 13 can drive the corresponding pressure plate 10 to move. In this process, the pressure plate 10 will drive the extrusion plate 8 to rotate and reset away from the tungsten-molybdenum rod raw material through the connecting block 9, and then the loading box 1201 continues to move, so that the horizontal axis 11 enters the top of the guide groove 1202, and the horizontal axis 11 will first push the trigger member 1206 to move. During this process, the trigger member 1206 compresses the second spring 1207, and the trigger member 1206 drives the locking head 1205 to move, and the locking head 1205 will be separated from the positioning hole on the loading box 1201, so that the horizontal axis 11 can drive the limit block 1203 to move and compress the first spring 1204. When the horizontal axis 11 passes through the limit block 1203 and enters the initial position in the guide groove 1202, the first spring 1204 will move the limit block 1203 to reset, and the second spring 1207 will drive the trigger member 1206 and the locking head 1205 to reset. Through the above operation, the eight extrusion plates 8 are alternately squeezed in groups of four;

[0055] S4: The wire drawing raw material processed by the extrusion plate 8 enters the wire drawing mouth formed by the outer die mouth 23 and the inner die mouth 24 through the inner connecting tube 21, thereby being processed and formed. During this process, the rotating loading tube 4 will drive the storage tube 22 to rotate, and the storage tube 22 will drive the first pressure rod 25 and the second pressure rod 26 to rotate. When the second pressure rod 26 is away from the two second arc plates 2703, the second pressure rod 26 no longer applies the closing pressure to the outer die mouth 23, so that the outer die mouth 23 is no longer worn by wire drawing. At this time, the first pressure rod 25 will be attached to the corresponding first arc plate 2702. At this time, the first pressure rod 25 will drive the corresponding inner die mouth 24 to perform the closing operation, so that the inner die mouth 24 can perform the wire drawing operation. The wire drawing operation is performed by alternating the closing of the inner die mouth 24 and the outer die mouth 23, thereby effectively improving the service life of the wire drawing die mouth.
