When the punching press pipe-reduction mold that the utility model provides uses, be arranged on pressing equipment, debug after the degree of depth, get a pipe cutting workpiece and be positioned over the position location of lower bolster die cavity oral area, press the operating switch button of pressing equipment, now part of the upper die starts descending, first guide pillar enters guide pillar chamber, drift and enters the inside of workpiece, play the effect of first correcting location, patrix is progressively about to down workpiece and is progressively pressed into lower bolster die cavity, patrix goes downwards at the end, and workpiece is also just pressed in lower bolster die cavity completely, and now the draw has moved.Then patrix resets, and the product that in lower bolster die cavity, the draw completes simultaneously also can be ejected counterdie along with the elastic ejection device of counterdie.For preventing that the product after the draw completes is bonded on patrix drift, is designed with stripper plate on patrix.Even if product is bonded on patrix drift, stripper plate also can eject patrix by product.Now, the draw operation of a product has just completed.
The device that the utility model provides has overcome the deficiencies in the prior art, can replace the use of traditional machine for shrinking, has not only improved production efficiency, greatly reduces production cost, and safety is also secure.
Brief description of the drawings
The punching press pipe-reduction mold schematic diagram that Fig. 1 provides for the utility model.
Detailed description of the invention
For the utility model is become apparent, hereby with a preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The punching press pipe-reduction mold schematic diagram that Fig. 1 provides for the utility model, described punching press pipe-reduction mold comprises upper die and lower die two large divisions.
Part of the upper die comprises upper bolster 1, and upper padding plate 2 is positioned at upper bolster 1 below, and train wheel bridge 5 is positioned at upper padding plate 2 belows, and upper bolster 1, upper padding plate 2, train wheel bridge 5 are used steady pin 3 and located and use 4 lockings of tightening up a screw to connect.Drift 9 and guide pillar 10 all, through being fixed on after stripper plate 8 on train wheel bridge 5, have the via hole of guide pillar 10 and drift 9 on stripper plate 8, stripper plate 8 is connected with train wheel bridge 5 by contour sleeve 6, spring 7 are housed for de-material on train wheel bridge 5.
Part of the lower die comprises die shoe 19, lower bolster 17 is positioned at die shoe 19 tops, lower plate 16 is positioned at lower bolster 17 tops, and lower bolster 12 is positioned at lower plate 16 tops, and lower bolster 12, lower plate 16, lower bolster 17 and the lower steady pin 13 of die shoe 19 use are located and used lower screw 14 lockings to be connected.On lower bolster 12, lower plate 16, have the guide pillar chamber of mating with guide pillar 10.Lower bolster 12 is provided with the die cavity mating with drift 9, and in lower bolster 12 die cavities, oral area is designed with pipe position location, and de-material piece 15 is housed on lower plate 16, after completing, product is ejected to lower bolster die cavity for the draw.De-material piece 15 belows are provided with elastic ejection device 18, and elastic ejection device 18 comprises push rod and spring, and spring withstands the anti-anti-avulsion material of push rod piece 15 and falls down and cause mould stuck.Die shoe 19 belows are provided with an independently lower roof plate 20, and lower roof plate 20 is connected with the liftout attachment on pressing equipment, and when the work of punching press pipe-reduction mold, the liftout attachment on pressing equipment is passed to the push rod in elastic ejection device 18 by lower roof plate 20 power.
Also very simple all of the operation principle of the punching press pipe-reduction mold that the utility model provides and method of operating.Punching press pipe-reduction mold is installed on the general pressing equipment such as punch press or hydraulic press, can carry out draw processing after having debugged the degree of depth.Because steady pin being housed on mould and guide pillar correcting being housed, installation and debugging mould saving time very.After die debugging is good, get a pipe cutting workpiece and be positioned over the position location of lower bolster die cavity oral area, press the operating switch button of pressing equipment, now part of the upper die starts descendingly, and first guide pillar 10 enters guide pillar chamber, drift 9 and enter the inside of workpiece, plays the effect of first correcting location, patrix is progressively about to down workpiece and is progressively pressed into lower bolster die cavity, patrix goes downwards at the end, and workpiece is also just pressed in lower bolster die cavity completely, and now the draw has moved.Then patrix resets, and the product 11 that in lower bolster die cavity, the draw completes simultaneously also can be ejected counterdie along with the elastic ejection device of counterdie.For preventing that the product 11 after the draw completes is bonded on patrix drift 9, is designed with stripper plate 8 on patrix.Even if product 11 is bonded on patrix drift 9, stripper plate 8 also can eject patrix by product.Now, the draw operation of a product 11 has just completed.The namely routine of pressing equipment action can complete the draw operation of a product, very simple, easy to operate.
The punching press pipe-reduction mold that the utility model provides can be to the quick draw processing of common metal pipe progress on the general pressing equipment such as punch press or hydraulic press by being arranged on, can replace machine for shrinking uses, make enterprise need not drop into substantial contribution and remove to buy machine for shrinking, can carry out draw processing as long as do a secondary above-mentioned punching press pipe-reduction mold, and the working (machining) efficiency of this punching press pipe-reduction mold is also far above machine for shrinking, thereby improved production efficiency, reduced cost, and safety is also secure.
