Abstract
The utility model discloses a light wall pipe single hole vertical stamping die, and relates to a stamping die. The light wall pipe single hole vertical stamping die comprises an upper die seat, a lower die seat and a male die. The male die comprises a male die seat and a male die pole. The male die seat is fixedly connected with the upper surface of the lower die seat. The male die pole is hinged with the die male seat through a rotating shaft. The free end of the male die pole is provided with a punch vertical to the male die pole. The punch is opposite to the lower die seat. The lower die seat is provided with a female die matched with the punch. The upper die seat is provided with a push pole, and the position of the push pole corresponds to the middle of the male die pole. The side wall of the male die pole is provided with a reinforced plate. According to the light wall pipe single hole vertical stamping die, structural strength and rigidity of the die are improved, service life of the die is prolonged, production efficiency is high, die cost is low, production quality is improved, the rejection rate is reduced, and practical applicability is achieved.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to the upright punch die of a kind of light wall pipe single hole.
Background technology
In punching production; Usually need punching on jatharapanvartanasana workpiece (like cylindrical member, tubular member, box part, large-scale covering etc.) sidewall; Generally be to use the cantilevered perforating die, the die of existing cantilevered perforating die is horizontally disposed with, and need be placed in towards the workpiece of side opening on the die; Vertical punch moves downward under the drive of forcing press, accomplishes the moulding of side opening.The strength of concave mould and the rigidity of existing cantilevered perforating die are poor, 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 cantilevered perforating die often makes the tube wall deformation of light wall pipe because impulse force is bigger, influences the quality of product, has increased percent defective in addition.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of light wall pipe single hole to found punch die, has improved the mould structure strength and stiffness; Prolonged the service life of mould, production efficiency is high, and die cost is low; Improve the quality of product, reduced percent defective, very practical.
The technical scheme of the utility model is: a kind of light wall pipe single hole founds punch die, comprises upper bolster, die shoe and punch, and said punch comprises convex mould base and convex die rod; Convex mould base is fixedly connected on the die shoe upper surface; Convex die rod is articulated on the convex mould base through rotating shaft, and the free end of convex die rod is provided with the drift vertical with convex die rod, and drift and die shoe are in opposite directions; Die shoe is provided with the die with the drift coupling; Upper bolster is provided with push rod, and the position of push rod is corresponding with the middle part of convex die rod, and the convex die rod sidewall is provided with stiffener.
As preferably, the end near drift on the convex die rod is provided with pin stop, has the through hole that is communicated with the die hole on the die shoe, and the diameter of this through hole is greater than the diameter in die hole.
As preferably, said drift and convex die rod are one-body molded, and drift and convex die rod all adopt the GCr15 steel to process, and die adopts carbide alloy to process, and die shoe is processed with convex mould base employing Q235 steel plate.
The beneficial effect of the utility model is: during use the light wall pipe workpiece is enclosed within on the convex die rod of the utility model the degree of depth of being inserted in according to the determining positions light wall pipe workpiece of wanting the moulding hole.Upper bolster is along with forcing press is descending when punching press, and push rod promotes convex die rod to lower swing, accomplishes the moulding of light wall pipe workpiece side cinclides; The die of the 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.The blanking pressure of the utility model is less, and the light wall pipe workpiece is to be enclosed within on the convex die rod, and therefore add man-hour its tube wall and can not be out of shape, good product quality, very practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as shown in Figure 1, a kind of light wall pipe single hole founds punch die; Comprise upper bolster, die shoe 8 and punch, said punch comprises convex mould base 7 and convex die rod 5, and convex mould base 7 is fixedly connected on die shoe 8 upper surfaces; In the present embodiment, as preferably, die shoe 8 adopts the Q235 steel plates to process with convex mould base 7; Good combination property, long service life.Convex die rod 5 is articulated on the convex mould base 7 through 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, said drift and convex die rod 5 are one-body molded, drift and convex die rod 5 all adopt the GCr15 steel to process, intensity is high, long service life.Die shoe 8 is provided with the die 1 with drift coupling, and in the present embodiment, as preferably, die 1 adopts carbide alloy to process.Upper bolster is provided with push rod 4, and the position of push rod 4 is corresponding with the middle part of convex die rod 5, and convex die rod 5 sidewalls are provided with stiffener 9, has improved the strength and stiffness of convex die rod 5.
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 position according to different situations adjustment pin stop 3.Have the through hole that is communicated with the 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 in die hole.
The operation principle of the utility model is following: during use light wall pipe workpiece 2 is enclosed within on the convex die rod 5 of the utility model the degree of depth of being inserted in according to the determining positions light wall pipe workpiece 2 of wanting the moulding 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, accomplishes the moulding of light wall pipe workpiece 2 areoles.
The above is merely a kind of embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and obvious mode of texturing etc., all should be included within the protection domain of the utility model.
