In this embodiment, when the clamping assembly 633 drives the centering rod 62 to clamp the end of the steel member, the power end of the driving motor 6338 drives the driving rod 6334 to rotate, and then the rotating driving rod 6334 synchronously drives the upper and lower driving gears 6332 to rotate, and the rotating gear 6332 drives the engaged driven gear 6333 to further drive the moving screw 6335 to move up and down, so that the transferring screw 6335 is linked with the moving table 6321 to move, and the centering rod 62 clamps the end surface of the steel member.

As shown in fig. 2, the moving assembly 631 includes:

a first toothed plate 6311, the first toothed plate 6311 being mounted on the moving rubbing part 300;

a second rack 6312, wherein the second rack 6312 is disposed above the first rack 6311, and the second rack 6312 is mounted on the base 100; and

Example two

As shown in fig. 2 to 4, in which the same or corresponding components as in the first embodiment are denoted by the same reference numerals as in the first embodiment, only the points of difference from the first embodiment will be described below for the sake of convenience. The second embodiment is different from the first embodiment in that: the rotating assembly includes:

a transmission gear set 6341, wherein the transmission gear set 6341 is mounted on the holder 61; and

and the transmission toothed plate 6342 is arranged on the fixed rubbing part 200.

In this embodiment, when the rotating assembly 634 simulates the rotating action of the steel part during thread rolling, when the rotating assembly is thread-rolled along the moving direction of the moving assembly 631 along the clamp base 61 through the transmission gear set 6341 on the clamp base 61, the transmission gear set 6341 transmits the rotating force to the centering rod 62 through the mutual transmission with the transmission gear plate 6342, so that the power drives the steel part to rotate through the centering rod 62, and the auxiliary rotation is performed during thread rolling, thereby improving the thread surface accuracy during thread rolling.

It is added that the driving gear set 6341 includes a centering gear 63411 and a guide gear 63412, the guide gear 63412 has at least one set, and the guide gear 63412 is engaged with the centering gear 63411.

In this embodiment, after the transfer assembly 632 transfers the steel piece to one side of the movable twisting portion 300, the guide gear 63412 is engaged with the transmission gear plate 6342, so as to drive the centering rod 62 to rotate when the steel piece is twisted, and the rotating speed of the centering rod 62 driving the steel piece to rotate is the same as the rotating speed of the steel piece twisted under the normal state, thereby ensuring that the steel piece does not slide relatively during the twisting to damage the twisted surface.

As shown in fig. 5 and 7, the oiling assembly 64 includes:

the circulating oil pipe 641 is connected to the upper and lower groups of the clamping seats 61 respectively;

an oil tank 642, wherein the oil tank 642 is disposed on the circulation oil pipe 641 above the top set of the holders 61;

a cooler 643, wherein the cooler 643 is disposed on the circulation oil pipe 641 below the bottom group of the holders 61;

an oil control assembly 644, wherein the oil control assembly 644 is disposed on the circulation oil pipe 641 between the oil tank 642 and the clamp seat 61;

an oil outlet 645, the oil outlet 645 being provided on the top set of centering bars 62;

the collecting port 646 is formed in the clamping seats 61 around the bottom group of the centering rods 62; and

a suction pump 647, wherein the suction pump 647 is arranged in the oil tank 642.

In the present embodiment, when the oil injection assembly 64 performs oil injection, that is, when the steel member reaches between the movable washbasin 300 and the fixed washbasin 200 for thread rolling, the oil control assembly 644 is opened, oil in the oil tank 642 is pushed out through the oil outlet 645 of the centering rod 62 by the suction pump 647, and when the steel member rotates for thread rolling, the oil is sufficiently replenished on the steel member, and the excessive falling oil reaches the collected oil 646 on the bottom side, and then the increased temperature of the oil due to heat exchange of thread rolling temperature is reduced under the cooling action of the cooler 643 (the cooler 643 is preferably an OR-1000 tubular cooler), and then the oil is continuously sucked into the oil tank 642 through the circulating oil pipe 641 by the suction pump 647.

Additionally, a fuel filling port (not shown) is provided at one side of the fuel tank 642.

In this embodiment, during the use of oil, the amount of oil in the oil tank 642 is continuously reduced, so that oil can be timely supplemented to the oil tank 642 through the oil filling port.

As shown in fig. 4-6, the oil control assembly 644 includes:

a valve seat 6441;

a spool 6442, said spool 6442 disposed within said valve seat 6441;

In this embodiment, when the oil control assembly 644 performs an oil control operation, when the pushing seat 6445 abuts against the triggering seat 6446 on the fixed rubbing portion 200, the valve element 6442 moves to the other side of the inner cavity of the valve seat 6441 under the elastic force of the elastic element 6443, so that the valve hole 6444 communicates with the upper and lower circulating oil pipes 641, thereby outputting the oil to the steel member, and it is necessary to supplement that, after the thread rolling is completed, the transferring assembly 632 can drive the pushing seat 6445 not to contact with the triggering seat 6446, and then return to the initial position.

As shown in fig. 6, the push seat 6445 includes:

a push rod 64451; and

a guide wheel 64452, the guide wheel 64452 being mounted at the end of the push rod 64451.

In this embodiment, to better realize the movement of the pushing seat 6445, the guide wheel 64452 on the pushing rod 64451 contacts with the surface of the triggering seat 6446, thereby reducing the friction.

As shown in fig. 4, one end of the trigger seat 6446 is provided with a guide notch 6447, and the guide width of the guide notch 6447 is greater than the maximum displacement of the push seat 6445.

In this embodiment, the guiding notch 6447 is used to facilitate the pushing seat 6445 to smoothly reach the triggering seat 6446.

The working steps are as follows:

step one, conveying and sorting, wherein steel pieces conveyed by the conveying part 400 at the tail end are guided into a sorting chamber 51 in the sorting part 500 one by one through a pushing piece 52;

secondly, centering the steel piece, namely, leading a screw 53 to rotate in the arranging cavity 51, attaching the steel piece to one side of a pushing piece 52, and leading the steel piece upwards to a positioning inserting ring 54 to finish centering;

step three, clamping the steel piece, wherein the clamping and conveying part 600 clamps two ends of the steel piece through a clamping assembly 633 on the driving mechanism 63;

step four, transferring the steel piece, wherein the clamped steel piece reaches one side of the movable twisting part 300 under the driving of the power of the transferring component 632, and the thread rolling is to be performed;

step five, auxiliary thread rolling, wherein when the moving rolling part 300 moves the thread rolling, the moving amount of the thread rolling is transmitted to the steel part in an auxiliary manner through the moving assembly 631, and the steel part is rotated in an auxiliary manner through the rotating assembly in an auxiliary manner;

step six, oiling the steel part, wherein when the steel part is twisted and rotated, the oil control assembly 644 controls the oil outlet 645 to be opened, the oil falls to the surface of the steel part, is rotationally coated by the twisted thread, is collected by the collection port 646, is cooled by the cooler 643 and then returns to the oil tank 642;

and step seven, separating the steel piece, wherein when the steel piece reaches the end part of the fixed twisting part 200, the clamping assembly 633 controls the centering rod 62 to be separated from the steel piece.
