Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of light-wall pipe single-hole vertical punching die.
Background technology
In punching production, usually need to punching on jatharapanvartanasana workpiece (such as cylindrical member, tubular piece, box part, large-scale covering etc.) sidewall, generally be to use cantilever type punching die, the die of existing cantilever type punching die is horizontally disposed with, the workpiece that needs is rushed side opening is placed on the die, vertical punch moves downward under the drive of forcing press, finishes the moulding of side opening.The strength of concave mould of existing cantilever type punching die and poor rigidity are easy to be thrust, and often change or keep in repair die, have reduced production efficiency, have increased die cost.When the less light-wall pipe of processing tube wall thickness, existing cantilever type punching die often makes the tube wall deformation of light-wall pipe because impulse force is larger, affects the quality of product, has increased percent defective in addition.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of light-wall pipe single-hole vertical punching die, has improved the mould structure strength and stiffness, prolonged the mold use life-span, production efficiency is high, and die cost is low, improve the quality of product, reduced percent defective.
The technical solution of the utility model is: a kind of light-wall pipe single-hole vertical punching die, comprise upper bolster, die shoe and punch, described punch comprises convex mould base and convex die rod, convex mould base is fixedly connected on the die shoe upper surface, and convex die rod is articulated on the convex mould base by rotating shaft, and the free end of convex die rod is provided with the drift vertical with convex die rod, drift and die shoe are in opposite directions, be provided with the die that mates with drift on the die shoe, be provided with push rod on the upper bolster, the position of push rod is corresponding with the middle part of convex die rod; Be provided with the triangle ribs on the convex mould base.
As preferably, the end near drift on the convex die rod is provided with pin stop, has the through hole that is communicated with die hole on the die shoe, and the diameter of this through hole is greater than the diameter of die hole.
As preferably, described drift and convex die rod are one-body molded, and drift and convex die rod all adopt the GCr15 steel to make, and die adopts carbide alloy to make, and die shoe and convex mould base adopt the Q235 steel plate to make.
The beneficial effects of the utility model are: during use the light-wall pipe workpiece is enclosed within on the convex die rod of the present utility model the degree of depth of being inserted in according to the determining positions light-wall pipe workpiece of wanting forming hole.Upper bolster is along with forcing press is descending when punching press, push rod promotes convex die rod to lower swing, finish the moulding of light-wall pipe workpiece side cinclides, die of the present utility model need not be horizontally disposed with, strength and stiffness are high, are difficult for being thrust, and guaranteed the continuity of producing, improve production efficiency, reduced die cost.Blanking pressure of the present utility model is less, and the light-wall pipe workpiece is to be enclosed within on the convex die rod, therefore adds man-hour its tube wall and can not be out of shape good product quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of light-wall pipe single-hole vertical punching die comprises upper bolster, die shoe 8 and punch, and described punch comprises convex mould base 7 and convex die rod 5, convex mould base 7 is fixedly connected on die shoe 8 upper surfaces, in the present embodiment, as preferably, die shoe 8 and convex mould base 7 adopt the Q235 steel plates to make, good combination property, long service life.Convex die rod 5 is articulated on the convex mould base 7 by rotating shaft 6, and convex die rod 5 can swing up and down along rotating shaft 6.The free end of convex die rod 5 is provided with the drift vertical with convex die rod 5, drift and die shoe 8 in opposite directions, in the present embodiment, as preferably, described drift and convex die rod 5 are one-body molded, drift and convex die rod 5 all adopt the GCr15 steel to make, intensity is high, long service life.Be provided with the die 1 with drift coupling on the die shoe 8, in the present embodiment, as preferably, die 1 adopts carbide alloy to make.Be provided with push rod 4 on the upper bolster, the position of push rod 4 is corresponding with the middle part of convex die rod 5; Be provided with the triangle ribs on the convex mould base 7, guaranteed the positional precision of convex mould base 7, convex mould base 7 displacements when avoiding punching press.
In the present embodiment, as preferably, the end near drift on the convex die rod 5 is provided with pin stop 3, makes things convenient for the location of light-wall pipe workpiece 2, and as preferably, pin stop 3 removably connects with convex die rod 5, convenient size and the position of adjusting pin stop 3 according to different situations.Have the through hole that is communicated with die hole on the die shoe 8, the diameter of this through hole is conveniently collected the waste material that is swept away greater than the diameter of die hole.
Operation principle of the present utility model is as follows: during use light-wall pipe workpiece 2 is enclosed within on the convex die rod 5 of the present utility model the degree of depth of being inserted in according to the determining positions light-wall pipe workpiece 2 of wanting forming hole.Upper bolster is along with forcing press is descending when punching press, and push rod 4 promotes convex die rod 5 to lower swing, finishes the moulding of light-wall pipe workpiece 2 areoles.
