Abstract

The utility model discloses a moveable bending and avoiding mould. The moveable bending and avoiding mould comprises a cutter body, and a cutter assistant body connected with the cutter body through a sliding mechanism. An obtuse angle gap is arranged on one side of the bottom of the cutter body. The obtuse angle gap is provided with a horizontal wall face and an inclined wall face. The cutter assistant body is attached to the inclined wall face compactly and can slide up and down along the face of the inclined wall. When the top of the cutter assistant body leans against the face of the horizontal wall, the bottom face of the cutter assistant body is aligned with that of the cutter body. The moveable bending and avoiding mould provided by the utility model is simple in structure, convenient to operate and low in cost, and parts machined by using the mould can be very conveniently disassembled from the mould.

Description

Movable bending keeps away position mould

Technical field

The utility model 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 utility model purpose is: 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.

The technical scheme of the utility model 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.

The utility model has the advantages that:

The movable bending of the utility model 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 utility model is further described:

Fig. 1 is the stereogram of the utility model embodiment;

Fig. 2 is the front view of the utility model embodiment;

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 42 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 41 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 the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
