Abstract

The invention discloses a movable bending clearance mold which comprises a cutter main body and a cutter auxiliary body connected with the cutter main body through a sliding mechanism, wherein an obtuse-angle notch is arranged on one side of the bottom of the cutter main body and provided with a horizontal wall surface and an inclined wall surface, and the cutter auxiliary body clings to the inclined wall surface and can slide vertically along the inclined wall surface. When the top of the cutter auxiliary body butts against the horizontal wall surface, the bottom surface of the cutter auxiliary body is parallel and level to the bottom surface of the cutter main body. The movable bending clearance mold has the advantages of being simple in structure, convenient to operate and low in cost, and parts processed through the mold can be taken down from the mold very conveniently.

Description

Movable bending keeps away position mould

Technical field

The present invention relates to mould applications, specifically is that a kind of movable bending keeps away position mould.

Background technology

Keep away a bending and be meant the operation that with each Edge Bend moulding of workpiece, finally becomes an opening part.Because each limit of part all needs bending; General keep away a Bending Mould bending after; Cutter is stuck in to be needed in the part just taking out after the part inclination; Can't in product, separate cutter behind the part bending of each Edge Bend consistent size, though some mould can be realized this operation, its structure is all comparatively complicated.

Summary of the invention

The present invention seeks to: to the problems referred to above, propose a kind of movable bending simple in structure, easy to operate, with low cost and keep away position mould, use the part of this Mould Machining to take off from this mould easily.

Technical scheme of the present invention is: described movable bending keeps away position mould; Comprise cutter body and the cutter accessory body that is connected with said cutter body through slide mechanism; Bottom one side of said cutter body is provided with the obtuse angle breach; This obtuse angle breach has horizontal wall surface and inclined wall; Said cutter accessory body is close to said inclined wall and is arranged also and can slide up and down along this inclined wall that when the top of said cutter accessory body propped up said horizontal wall surface, the bottom surface of said cutter accessory body was concordant with the bottom surface of said cutter body.

Said slide mechanism by two braces, be connected in the long lumbar hole of offering on three alignment pins and the said cutter body between these two braces and constitute; Said long lumbar hole and said inclined wall parallel; Described two braces are fixed on the said cutter accessory body through two alignment pins wherein, and the another one alignment pin is arranged in the said long lumbar hole and can slides within it.

Said cutter body is identical with the bottom shape of cutter accessory body, is arc, U-shaped or V-arrangement.

Advantage of the present invention is:

The movable bending of the present invention keeps away position mould and mainly is made up of cutter body and cutter accessory body, links to each other through slide mechanism between cutter accessory body and the cutter body.When cutter body is exerted pressure; Cutter accessory body and cutter body merge the back and accomplish the bending to part; When cutter body does not receive when exerting pressure; The cutter accessory body in self gravitation effect lower edge the cutter body hypotenuse to lower slider, thereby the side-to-side dimensions of entire die bottom inwardly contracted and diminish, and then can part easily be taken out.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

Fig. 1 is the stereogram of the embodiment of the invention;

Fig. 2 is the front view of the embodiment of the invention;

Wherein: 1-cutter body, 2-cutter accessory body, 3-obtuse angle breach, 31-horizontal wall surface, 32-inclined wall, 4-slide mechanism, 41-brace, 42-alignment pin, 43-long lumbar hole.

The specific embodiment

As depicted in figs. 1 and 2, the movable bending of present embodiment keeps away position mould, comprises cutter body 1 and the cutter accessory body 2 that is connected with said cutter body through slide mechanism 4.Bottom one side of said cutter body 1 is provided with obtuse angle breach 3 (being generally 135 °), and this obtuse angle breach has horizontal wall surface 31 and inclined wall 32.Said cutter accessory body 2 is close to said inclined wall 32 and is arranged and can slide up and down along this inclined wall, and when the top of said cutter accessory body 2 propped up said horizontal wall surface 31, the bottom surface of said cutter accessory body 2 was concordant with the bottom surface of said cutter body 1.Said cutter body 1 is identical with the bottom shape of cutter accessory body 2, is arc, U-shaped or V-arrangement, so that workpiece is carried out bending.

Shown in seeing figures.1.and.2; Above-mentioned slide mechanism 4 (only illustrates one by two braces 41 among the figure; Another is positioned at the back side, is blocked), be connected in the long lumbar hole of offering on three alignment pins 32 and the said cutter body 1 between these two braces 43 and constitute.Said long lumbar hole 43 parallels with said inclined wall 32; Described two braces 42 are fixed on the said cutter accessory body 2 through two alignment pins 42 (being two in said three alignment pins) wherein and (are shaped on two locating holes on the cutter accessory body; Be used to assemble this two alignment pins), another one alignment pin 42 is arranged in the said long lumbar hole 43 and can in this long lumbar hole, slides.

The operation principle of present embodiment is: when processing need keep away the position or the part of " ∑ " shape is arranged; Cutter body 1 end face exerted pressure cutter body 1 and cutter accessory body 2 are all moved down; When the bottom surface of cutter accessory body 2 with after part to be processed contacts; The inclined wall 32 of cutter accessory body 2 breach 3 along the obtuse angle upwards slides, and after the end face of cutter accessory body 2 propped up the horizontal wall surface 31 of obtuse angle breach 3, simultaneously part exerted pressure concordant with cutter body 1 bottom surface of cutter accessory body 2 bottom surfaces reached final effect.Inclined wall 32 slides downwards automatically in self gravitation effect lower edge when cutter body 1 does not receive when exerting pressure cutter accessory body 2; The side-to-side dimensions of entire die bottom inwardly contracts and diminishes; Part after the processing breaks away from the bottom surface of cutter body 1 and only is embedded on the bottom surface of cutter accessory body 2 under the drive of cutter accessory body 2; Thereby make things convenient for part to take off, like Fig. 2.

Certainly, the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
