Abstract

The invention discloses a mould for trimming mouths of outsides cover parts. The mould comprises an upper mould, a lower mould, a guide post and a guide sleeve, wherein the upper mould comprises a punch handle, a punch plate, fixing plates and upper discharge blocks; the lower mould comprises lower mould plates, a lower base plate, a positioning block and pressing plates; a pneumatic material pressing device and a pneumatic material discharge device are arranged in the upper and lower moulds of the trimming mould respectively; and the lower mould is provided with a convex mould and concave moulds at the same time. The trimming mould has the following beneficial effects: through the trimming mould disclosed by the invention, the vertical pressure of a punch is changed into horizontal pressure, and the redundant materials at the mouths of round or rectangular metal or non-metal outsides cover parts are cut off; meanwhile, compressed air is used as power to drive a material pressing device to press a part to be processed, and after processing, the pneumatic material discharge device mounted on the lower mould of the mould discharges the part; and the labor intensity of workers can be lessened, the processing time can be reduced, and economical benefits can be increased.

Description

A kind of outer cover class part oral area shaving die

Technical field

The present invention relates to a kind of diel, especially a kind of outer cover class part oral area shaving die.

Technical background

Methods such as at present in the production process, outer cover class part oral area excess stock adopts car mostly, mills, line cutting are removed, and the shortcoming of these processing methods is that long processing time, labor strength are big, production efficiency is low, and cost is high.

The utility model content

The purpose of this invention is to provide a kind of outer cover class part oral area shaving die structure, improve outer cover class part production efficiency and presentation quality.

The objective of the invention is to realize through following approach:

Outer cover class part oral area shaving die according to the invention; Form by upper die and lower die and guide pillar, guide pin bushing; Wherein patrix comprises punch-holder shank, nest plate, fixed head, and last skewback, counterdie comprise lower bolster, lower bolster, locating piece and pressing plate; Be respectively equipped with pneumatic material pressing device and pneumatic device for discharging in this shaving die upper and lower mould simultaneously, punch and die are installed on the counterdie simultaneously.

The pneumatic material pressing device of said upper mould comprises breather pipe, cylinder block, Stroke Control pipe, protective sleeve and eccentric swage; Breather pipe is fixed in the nest plate of patrix and with cylinder block and is communicated with; Cylinder block is fixed between the fixed head of nest plate bottom surface and patrix, movable successively Stroke Control pipe, protective sleeve and the eccentric swage installed in the cylinder block.

The pneumatic discharge device of said counterdie comprises breather pipe, air valve, and air valve is connected the breather pipe end and is fixed on the lower bolster side of counterdie, and the other end of breather pipe is communicated with the centre bore of locating piece.

Said mould die comprises vertical die and horizontal die, counterdie also is provided with die socket, convex mould base, backing pin and spring simultaneously; Lower bolster, lower bolster, convex mould base, pressing plate connect from bottom to up successively; Vertical die, horizontal die, backing pin and spring are installed in the die socket; Locating piece and punch are connected convex mould base and die center, and pressing plate is pushed down vertical die, horizontal die and backing pin and the spring that is installed in the die socket the inside.

Adopt the present invention of such scheme to utilize the special construction of mould to change over horizontal pressure force to the pressure at right angle of punch press, metal or nonmetallic circle or rectangle outer cover class part oral area excess stock are excised.Use compressed air to drive the part that eccentric swage is pushed down needs processing as power simultaneously, after machining, the blowing plant that lower mould is installed draws off part.Can reduce working strength of workers, reduce process time, increase economic efficiency.

The specific embodiment

Below in conjunction with the accompanying drawing instance the present invention is elaborated:

As shown in the figure; Outer cover oral area shaving die according to the invention is made up of upper die and lower die and guide pillar, guide pin bushing, and wherein patrix comprises punch-holder shank 1, nest plate 2, fixed head 4, last skewback 5; Counterdie comprises lower bolster 6, lower bolster 19, locating piece 14 and pressing plate 15; Be respectively equipped with pneumatic material pressing device and pneumatic device for discharging in this shaving die upper and lower mould simultaneously, pneumatic material pressing device comprises breather pipe, cylinder block 3, Stroke Control pipe 11, protective sleeve 12 and eccentric swage 13, and breather pipe is fixed in the nest plate of patrix and with cylinder block and is communicated with; Cylinder block 3 is fixed between the fixed head 4 of nest plate bottom surface and patrix; Movable successively Stroke Control pipe 11, protective sleeve 12 and the eccentric swage 13 installed in the cylinder block, patrix punch-holder shank 1 links to each other with nest plate 2 in addition, and nest plate 2 bottom surface four directions are equipped with skewback 5.

The pneumatic discharge device of counterdie comprises breather pipe 21, air valve 22, and air hose 22 is connected the breather pipe end and is fixed on the lower bolster side of counterdie, and the other end of breather pipe links to each other with the centre bore of locating piece 14.Die comprises vertical die 7 and horizontal die 17, counterdie also is provided with die socket 16, convex mould base 18, backing pin 8 and spring 20 simultaneously; Lower bolster 6, lower bolster 19, convex mould base 18, pressing plate 15 connect from bottom to up successively; Vertical die 7, horizontal die 17, backing pin 8 and spring 20 are installed in the die socket 16; Locating piece 14 is connected convex mould base 18 and die center with punch 9, and pressing plate 15 is pushed down vertical die 7, horizontal die 17 and backing pin 8 and the spring 20 that is installed in the die socket the inside.

The concrete course of work of outer cover oral area shaving die of the present invention is:

After mould correctly is installed on the punch press, adjusts shut height and be communicated with compressed air, let protective sleeve 12; Eccentric swage 13 reaches the tram under compressed-air actuated effect, counterdie is connected compressed air, closes air valve 22; Empty trial run punch press and mould, normal after, the part of needs processing accurate location on locating piece 14; Descending along with slider of punch then, eccentric swage is pushed down part under the compressed air effect, and slide block continues descending the time; The outer wall arrival tram that protective sleeve 12 encases part keeps motionless afterwards, and at this moment, slider of punch continues descending; Last skewback 5 order that is installed on the nest plate drives the vertical die 7 and horizontal die 17 horizontal movements that is installed on the counterdie, and unnecessary material removal on following outer cover part of acting in conjunction of vertical die 7 and horizontal die 17 and punch 9 continues the waste material discharge of being excised when descending; In the process that slider of punch returns then, vertical die 7 turns back to initial position with horizontal die 17 after top shoe 5 is thrown off, and eccentric swage 13 continues to push down part up to last; Counterdie separates fully, after slider of punch is got back to initial point, opens the air valve 22 of counterdie; Compressed air draws off the part that processes, and accomplishes an operation cycle.

The part oral area that outer cover oral area shaving die of the present invention processes is smooth, does not need other operation to get final product, and has played and has shortened the process time that the outer cover oral area is cut edge, and has improved work efficiency, has reduced the effect of cost.Its shortcoming is the punch cutting edge easy abrasion of waste material place of incision, need select reasonable mold materials for use, and in use simultaneously, the punch press operation will be stablized, and will control the service life that could prolong mould well to the Molded Depth degree.
