Abstract

The utility model discloses a detachable multiple closing-in forming die for tubular goods, comprising an upper die holder, an upper back plate, a cavity die, a lower die holder, a lower back plate, a male die positioning plate, a male die, a die handle, a connection bolt, characterized in that: the die handle, the upper die holder and the cavity die are all provided with center holes and a knockout rod is slidably arranged in the center hole of the die handle and a bolt is fixed at the lower end of the knockout rod and the bolt is in screw connection with an forming knockout block in the cavity die. A transversal top-tightening bolt is arranged on the male die positioning plate and an adjustment mat sleeved outside the male die is arranged on the male die positioning plate. The detachable multiple closing-in forming die for tubular goods has advantages of low cost and short time limit for a project, and is especially suitable for multiple closing-in forming of middle, small order of tubular goods.

Description

The mould that repeatedly closes up that changes that is used for tubing
Technical field
The utility model relates to a kind of repeatedly closing in mould that is used for tubing.
Background technology
In the processing of punching parts, be subjected to the restriction of pressing equipment, the pull and stretch height is surpassed half part of common slider of punch stroke, if come drawing and forming with steel plate, stamping procedure is more, mould complexity and expense height, the mould safety in utilization is poor, often use the tubing blank to substitute steel plate in this case and come moulding, workpiece 16 is a kind of dust covers that our factory is produced shown in figure one, this part height dimension 90mm, considerably beyond half (half of the stroke of general common 80T or 100T punch press is 65mm) of stroke of common 80T or 100T punch press, the tubing that for this reason uses Φ 70X1.2 is by closing up and enlarging is finished, need four road closing in operations just can reach as shown in the figure shape by calculating this part with the enlarging operation, conventional design is to make the quadruplet mould to come this part of moulding, but the die cost height, manufacturing time is long.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of mould that repeatedly closes up that changes that is used for tubing is provided, and the advantage that it has, and cost is low, the duration is short is in being specially adapted to, the moulding of repeatedly closing up of the tubing of small lot.
For achieving the above object, the mould that repeatedly closes up that changes that is used for tubing of the present utility model, comprise upper bolster, upper padding plate, die, die shoe, lower bolster, punch location-plate, punch, die shank, connecting bolt, it is characterized in that die shank, upper padding plate and die are equipped with centre bore, be provided with knockout rod in the centre bore of die shank slidably, the lower end of knockout rod is installed with screw, moulding dnockout piece in this screw and the die is by being threaded, and punch cooperates the formation die cavity with moulding dnockout piece.
During use, tubing is placed on the punch, die shank is loaded on the hydraulic press, and upper bolster, upper padding plate, die, knockout rod, moulding dnockout piece descend with die shank, and moulding dnockout piece pushes to finish once to tubing and closes up; In the time of need descending road closing in operation, in the punch location-plate, take out punch, the punch of next procedure is changed, again moulding dnockout piece is taken off the moulding dnockout piece of changing next procedure and get final product.
As further improvement of the utility model, on the punch location-plate, be provided with the horizontal screw that holds out against; Can accurately locate punch.
As further improvement of the utility model, on the punch location-plate, also be provided with the adjusting pad that is placed in outside the punch; Can carry out processing and forming to the tubing of differing heights.
In sum, the utility model only need be changed punch and moulding dnockout piece, just can finish multiple tracks closing in operation, need not to make many molds, and changes conveniently, and the advantage of have that cost is low, the duration is short is in being specially adapted to, the moulding of repeatedly closing up of the tubing of small lot.
Description of drawings
Fig. 1 is the front view of target workpiece.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the front view of employed four groups of punch and moulding dnockout piece among the embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
By shown in Figure 2, this is used for the mould that repeatedly closes up that changes of tubing, comprise upper bolster 1, upper padding plate 2, die 3, die shoe 4, lower bolster 5, punch location-plate 6, punch 7, die shank 8, connecting bolt 9, wherein punch 7 and punch location-plate 6 are for being slidingly matched, is the gap 0.04? .05mm between, on punch location-plate 6, be provided with the horizontal screw 10 that holds out against, can hold out against, on punch location-plate 6, also be provided with the one group of adjusting pad 11 that is placed in outside the punch 7 punch 7; Die shank 8, upper padding plate 2 and die 3 are equipped with centre bore, be provided with knockout rod 12 in the centre bore of die shank 8 slidably, the lower end of knockout rod 12 is installed with screw 13, moulding dnockout piece 14 in this screw 13 and the die 3 is by being threaded, is gap between moulding dnockout piece 14 and the die 3 0.04? .05mm between, punch 7 cooperates the formation die cavity with moulding dnockout piece 14.
During use, tubing 15 is placed on the punch 7, die shank 8 is loaded on the hydraulic press, upper bolster 1, upper padding plate 2, die 3, knockout rod 12, moulding dnockout piece 14 descend with die shank 8,15 extruding of 8 pairs of tubing of moulding dnockout piece are finished once and are closed up, when die shank 8 returned, moulding dnockout piece 14 and knockout rod 12 glided by deadweight; In the time of need descending road closing in operation, unclamp and hold out against screw 10, take out punch 7 in punch location-plate 6, the punch of next procedure is changed, locking holds out against screw 10 again, moulding dnockout piece 14 is taken off the moulding dnockout piece of changing next procedure again; Obtain workpiece 16 as shown in Figure 1, only need to use successively as shown in Figure 3 four groups of punch and moulding dnockout piece to get final product, need not to make many molds, and change convenient, the advantage of have that cost is low, the duration is short is in being specially adapted to, the moulding of repeatedly closing up of the tubing of small lot.
