Abstract

The invention discloses an inclined hole punching die for a workpiece with a conical surface. A driving device drives a die shank to move downwards, the die shank drives an upper die holder to move downwards, and both a press block on the upper die holder and a material press plate move downwards together; the material press plate is guided by a die guide rod to slide along the die guide rod, makes contact with the workpiece which is placed on a lower female die at first, and tightly presses the workpiece so as to conduct punching; the upper die holder continues moving downwards, so that the extrusion surface of an inclined block acts on a male die and extrudes the male die, the male die conducts inclined movement, and punched holes can be machined in a mode of being perpendicular to the surface of the workpiece. Due to the fact that a punching groove is formed in the lower female die, the male die accomplishing machining is inserted into the punching groove, and waste generated by punching is pushed into the punching groove, and can fall off from a material discharging channel. According to the inclined hole punching die, perpendicular punching can be conducted on the workpiece with the conical surface, the two symmetrical punched holes can be machined at one time, efficiency is high, machining quality is high, and the inclined hole punching die is safe and reliable.

Description

Conical surface workpiece Punching Die of Oblique Hole
Technical field
The present invention relates to punching, punching, cut, stamping-out, cut-out except cutting or the mould that uses of extruding, be specifically related to a kind of conical surface workpiece Punching Die of Oblique Hole.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the punching of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.Cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab > 1.5mm) two kinds.For the workpiece of the conical surface, its machined surface is not a plane, and difficulty of processing is comparatively large, and needs during punching to consider processing request, carries out punching processing, be proposed higher requirement to mould and drift perpendicular to surface of the work.
Summary of the invention
The object of the present invention is to provide a kind of conical surface workpiece Punching Die of Oblique Hole, punching can be carried out on the conical surface of workpiece, and make the punching processed can be vertical with machined surface.
For achieving the above object, technical scheme of the present invention is: conical surface workpiece Punching Die of Oblique Hole, comprise die shoe and upper bolster, described die shoe is fixed with vertical guided mode bar, described die shoe is fixed with lower cavity die, described lower cavity die is provided with two symmetrical jet-beddings, described jet-bedding is vertical with the surface of lower cavity die, described lower cavity die with run through the material dropping channel being provided with and being communicated with jet-bedding in die shoe, described guided mode bar upper sliding sleeve is provided with holding pad, described holding pad is positioned at the top of lower cavity die, forms workpiece chamber between described holding pad and lower cavity die; Described holding pad is provided with two symmetrical punch, and the end of punch is provided with drift, and described punch and jet-bedding are positioned on straight line, is provided with punch back-moving spring in described holding pad; Be fixed with die shank above described upper bolster, described upper bolster slides is provided with guide pillar, and the end winding support of described guide pillar is on holding pad, and described guide pillar is provided with stage clip; The below of described upper bolster is fixed with a briquetting, and the lower surface of described briquetting is provided with two compressive planes vertical with punch.
When adopting technique scheme, drive die shank to move downward by drive unit, die shank drives upper bolster to move downward, and the briquetting on upper bolster and holding pad together move downward.Wherein holding pad slides along guided mode bar under the guiding of guided mode bar, and first holding pad contacts the workpiece be placed on lower cavity die, by Work-sheet pressing, in order to punching.Upper bolster continues to move downward, and makes the compressive plane of skewback act on punch, and extruding punch, make punch oblique movement, the Surface Machining perpendicular to workpiece goes out punching.Owing to being provided with jet-bedding on lower cavity die, completing the punch after processing and inserted in jet-bedding, and the waste material swept away has been headed in jet-bedding, made it drop from material dropping channel.The present invention can carry out vertical punching to the workpiece going out the conical surface, and time processing can go out two symmetrical punchings, and efficiency is higher, and crudy is high, safe and reliable.
Further, described lower cavity die is fixed on die shoe by sunk screw.
Further, the top of described holding pad is fixed with a pressing plate by screw.The effect of solid punch can be played by pressing plate, conveniently punch changed and safeguard.
Further, described upper bolster is provided with the shank hole run through, and the end of described die shank contacts with the upper end of briquetting through shank hole.Power can directly be applied on briquetting by die shank by this setting, optimizes the structure of punch die.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of conical surface workpiece Punching Die of Oblique Hole embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, conical surface workpiece Punching Die of Oblique Hole of the present invention, comprise die shoe 1 and upper bolster 2, die shoe 1 is fixed with vertical guided mode bar 3, die shoe 1 is fixed with lower cavity die 4, described lower cavity die 4 is provided with two symmetrical jet-beddings, described jet-bedding is vertical with the surface of lower cavity die 4, described lower cavity die 4 with run through the material dropping channel 5 being provided with and being communicated with jet-bedding in die shoe 1, guided mode bar 3 upper sliding sleeve is provided with holding pad 6, holding pad 6 be provided with guided mode bar cover 31.Described holding pad 6 is positioned at the top of lower cavity die 4, forms workpiece chamber between described holding pad 6 and lower cavity die 4; Described holding pad 6 is provided with two symmetrical punch 7, and the end of punch 7 is provided with drift, and punch 7 and jet-bedding are positioned on straight line, are provided with punch back-moving spring 61 in holding pad 6.Be fixed with die shank above upper bolster 2, upper bolster 2 slides is provided with guide pillar 8, and the end winding support of described guide pillar 8 is on holding pad 6, and described guide pillar 8 is provided with stage clip.The below of upper bolster 2 is fixed with a briquetting 9, and the lower surface of described briquetting 9 is provided with two compressive planes vertical with punch 7.Lower cavity die 4 is fixed on die shoe 1 by sunk screw.The top of holding pad 6 is fixed with a pressing plate 10 by screw.The effect of solid punch 7 can be played by pressing plate 10, conveniently punch 7 changed and safeguard.Upper bolster 2 is provided with the shank hole run through, and the end of described die shank contacts with the upper end of briquetting 9 through shank hole.Power can be directly applied on briquetting 9 by die shank by this setting, optimizes the structure of punch die.
