[0002] A thread rolling machine is a device for machining threads on the outer surface of a cylindrical workpiece. It usually includes two thread rolling plates with the same tooth profile on the surface. By driving the two thread rolling plates to move relative to each other, the workpiece between the two thread rolling plates can be rolled with threads, and the thread machining can be completed only by one round trip, with a quite high speed. However, when the existing metal wire is subjected to thread machining, since the metal wire is usually in coils, it is necessary to straighten and cut the metal wire before thread rolling. This requires multiple clampings and needs to be completed by different machines, resulting in high production costs, reduced production efficiency, increased labor intensity of workers, and waste of human, material and financial resources.

[0022] Specifically, as Figure 2As shown in the figure, the straightening mechanism 2 in the present application includes a first straightening assembly 7 and a second straightening assembly 8.

The outer edges of the first straightening rollers 9 and the second straightening rollers 10 are both provided with grooves for cooperating with the wire rod. During the conveying process of the wire rod, its two sides respectively cooperate with the grooves of the two rows of first straightening rollers 9 and with the grooves of the two rows of second straightening rollers 10, so as to straighten the wire rod in the vertical direction and then in the horizontal direction in sequence.

[0023] In another specific embodiment, the feeding mechanism 3 includes a driving roller shaft 12 and a driven roller shaft 13 rotatably arranged on the mounting base. A feeding gap 14 for cooperating with the wire rod is arranged between the driving roller shaft 12 and the driven roller shaft 13. And one end of the driving roller shaft 12 is connected with a first driving device for driving it to rotate. Specifically, the first driving device can adopt a motor. The motor is in transmission connection with the driving roller shaft 12 and can drive the driving roller shaft 12 to rotate, so that the driving roller shaft 12 and the driven roller shaft 13 cooperate to convey the metal wire rod to the cutting mechanism 4.

[0024] As Figure 3 and Figure 4 As shown in the figure, in the present application, the cutting mechanism 4 may include a seat body 15 fixedly installed on the machine base 1 and a cutting assembly arranged on the seat body 15. The seat body 15 is vertically and fixedly installed on the machine base 1 and is perpendicular to the conveying direction of the metal wire rod. The seat body 15 is provided with a limiting hole 16 for the metal wire rod to pass through. By providing the limiting hole 16, it can prevent the metal wire rod from shaking when it is conveyed to the cutting mechanism 4, so as to facilitate the cutting mechanism 4 to cut the metal wire rod. And a cutting plane 17 is arranged on the side of the seat body 15 facing away from the feeding mechanism 3. The cutting assembly includes a cutting seat 18 and a first driving structure. The cutting seat 18 is movably installed on the cutting plane 17 and is provided with a cutter head 19 for cooperating with the cutting plane 17.

By adopting the above structure to form the first driving structure and the second driving structure, the action interval between the first driving structure and the second driving structure can be accurately controlled, so as to realize the timely pushing of the metal wire cut by the cutting mechanism 4 by the pusher mechanism 5, and the structure is simple.

[0029] A blanking and thread rolling machine of the utility model is provided with a straightening mechanism 2, a feeding mechanism 3, a cutting mechanism 4, a pushing mechanism 5 and a thread rolling mechanism 6. During the processing, the straightening mechanism 2 can straighten the metal wire, and then the feeding mechanism 3 conveys the straightened metal wire to the cutting mechanism 4 to be cut into the required length. Then, the pushing mechanism 5 pushes the cut metal wire to the thread rolling mechanism 6 for thread rolling processing, so as to complete the straightening, cutting and thread rolling processing of the metal wire on one processing device, without multiple clamping and without using different machines to cooperate for processing, improving the thread rolling processing efficiency of the metal wire.
