Detailed description of the invention

Embodiment one:

The present embodiment is a kind of heading machine, as shown in Figure 1, 2, 3.The present embodiment includes: be arranged on horizontal lathe bed 1 The ram 2 of horizontal reciprocating movement, on described ram, annular array installs multiple drifts 3 with formpiston, described lathe bed phase Position to drift arranges the die box 4 of intermittent rotary, and described die box is cylindrical, and the end face of described cylinder is with described Drift is relative, the multiple station 5 with former of annular array, annular array drift on the end face of described ram on described end face Alignment pins 6 several with annular array, described former location hole with detent fit multiple relative to the end face annular array of drift 7。

Heading machine described in the present embodiment is the one in horizontal cold headers, has reciprocator to drive ram to move back and forth (in Fig. 1, arrow B represents), and the rotation die box (the die box direction of rotation that in Fig. 1, arrow C represents) with mould.There is rotation Turn the cooperation of die box and ram, carry out the cold-heading processing of multistation.

For the location of mould, the present embodiment arranges alignment pin on ram, is provided with location on rotation die box simultaneously Hole.The length of alignment pin is slightly longer than drift, is so contacting on former before workpiece at drift, and alignment pin is already inserted into hole, location In, position between die box and plug rotating, reach mould locating effect.

For positioning accurately, guide cone can be set at the head of alignment pin, to adapt to rotate die box in rotation During produce rotation error.

Alignment pin can arrange one or two, or more, depending on the intermittent rotary angle according to rotation die box.

Embodiment two:

The present embodiment is the improvement of embodiment one, is the embodiment one refinement about alignment pin.Determining described in the present embodiment The head of position pin is provided with guide cone 601, as shown in Figure 4.
