Description

Heading machine liftout transmission device

Technical field

The utility model relates to a kind of apparatus of heading machine, particularly a kind of heading machine liftout transmission device that drives the action of heading machine knockout pin.

Background technology

General heading machine, as TaiWan, China patent announcement number No. 331193 " two moulds four are towards heading machine " novel patent case, being provided with two in heading machine is divided into the left and right position and respectively has the main mould of die cavity, in each die cavity, be respectively equipped with iron wire with anchor clamps charging in regular turn, to carry out back and forth punching press towards each die cavity that cooperates respectively with the upper and lower punch die of two couples of matrix arrangement form setting by driving and reversing mechanism again, so iron wire will be processed as the semi-finished product of screw.

On aforementioned two pairs, the installation form of following punch die such as Fig. 8 and (Fig. 8 shown in Figure 9, Fig. 9 is the schematic perspective view of prior art heading machine), with in last, upper/lower positions respectively be provided with a upper punch nib 61 and once the paired mode in punch die hole 62 be installed on the die shoe 60, described upper trimming die 63 and following punch die 64 are plugged in the upper punch nib 61 and following punch die hole 62 that cooperates, when the die shoe 60 of driving and reversing mechanism front end towards each die cavity that cooperates action of advancing and retreat, die shoe 60 is done successively, when move following two sections position, each die cavity that can cooperate towards the place ahead with upper trimming die 63 or following punch die 64 respectively carries out punching press repeatedly, because described die cavity is divided into a left side, therefore right position and by anchor clamps charging in regular turn can carry out the processing technology of four strokes to iron wire with the advance and retreat of die shoe 60 4 times.The mechanism of aforementioned two die cavitys can cooperate two pairs of upper and lower punch dies 63,64 to constitute four-stroke processing technology, and change when being made as three left and right die cavitys arranged side by side when aforementioned two die cavitys, then be to cooperate the upper and

lower punch die

63,64 of three pairs of cooperation positions to finish the processing technology of three mould six-strokes.

The existing heading machine of producing screw with three mould six-strokes, (Figure 10 is the structural scheme of mechanism of prior art heading machine side-looking) as shown in figure 10, the position of corresponding each die cavity wears a knockout pin 71 respectively in the front side of support 70, the above punch die of difference during manufacturing, when the die cavity that following punch die cooperates towards the place ahead carries out repeatedly punching press, instantly after punch die finishes towards the die cavity punching press that cooperates, be arranged at of camshaft 73 rotations of the other power transmission shaft 72 of support 70 sides this moment with tooth umbrella shape drive support 70 the place aheads of front end, go to and make the cam 74 of combinations around the camshaft 73 promote the state of oscillating deck 75 up, make that oscillating deck 75 is the axle center with the rear end of bottom, front end with each knockout pin 71 of push rod spare 76 pushing tows of top combination, the workpiece of each die cavity released inwardly and can perhaps directly the finished product in the die cavity of the rightmost side be released and fall the effect of collection to reach with anchor clamps towards next die cavity charging.

Aforementioned existing with the other power transmission shaft 72 drive camshafts 73 of support 70 sides; cam 74 and each oscillating deck 75 action; though the design that ejects knockout pin 71 with each push rod spare 76 can be released the workpiece in the die cavity inwardly again; but because power transmission shaft 72 is except drive cam shaft 73; also to bear the mechanism that promotes on the support 11 other; therefore when the power resources of heading machine drive the rear end of power transmission shaft 72 with the engagement of umbrella shape tooth; cause the generation of umbrella shape tooth explosion problem because load is excessive through regular meeting; in addition; because before power transmission shaft 72 edges; the rear is longer to the transmission distance of extending; therefore the problem that action postpones also takes place in the time point of transmission easily, can't promote the action of each knockout pin 71 with accurate way.
