Description
Technical field
The present invention relates to a kind of necking die, particularly relate to a kind of metal pipe material pipe end pipe end shrink mouth mould.
Background technology
At present reducing is realized to tubing, main employing machine for shrinking carries out pressure receipts or particular manufacturing craft carries out punching press, machine for shrinking mainly adopts the mode of spinning, spinning is fixed on the mould of spinning machine by dull and stereotyped or hollow blank, while blank is with lathe main axis, with spinning roller or catch up with rod to stress on blank, make it the plastic deformation producing local.Under the feed motion of spinning roller and the rotary motion acting in conjunction of blank, make the plastic deformation of local expand to all surfaces of blank step by step, and be close to mould, complete the rotary pressing processing of part.Spinning is a kind of special manufacturing process.The drawing of various shape rotary body, flange, reducing, the technique such as bulging and crimping can be completed by spin-on process; When relating to some bend pipes, machine for shrinking then can not realize clamping, and bend pipe is rotated; Particular manufacturing craft then needs to be placed on by tubing on patrix or counterdie, is realized the plastic deformation of tubing by the mutual punching press of upper and lower mould, so machine for shrinking and particular manufacturing craft are mainly used for straight tube processing, larger to the restriction of pipe geometry.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and does not limit pipe geometry, the fixed necking die of tubing in draw process.
For overcoming the above problems, the invention provides a kind of metal pipe material pipe end shrink mouth mould, comprising sleeve pipe, clamping head, tensioning spring, frame and driving oil cylinder; Cannula center has conical through-hole, and be sleeve pipe conical through-hole, casing pipe sleeve is loaded on described clamping head, the ring flange that the piston that sleeve pipe periphery is provided with described driving oil cylinder is fixedly connected with; Clamping head comprises polylith separate slider, is combined into taper, coordinates with sleeve pipe conical through-hole, and when clamping head is combined into taper, its inner formation one through hole, be clamping head through hole, the top of clamping head through hole is tapered, is clamping head taper hole, in order to holding workpiece; Tensioning spring is arranged in clamping head through hole, and the slider bottom of described composition clamping head is connected with housing slide; Described driving oil cylinder is fixedly connected with frame.
Because clamping head is combined into taper by multiple separate slider, and inside is provided with tensioning spring, as long as the stroke of sleeve pipe is no more than preset range, clamping head outer wall will be close to the taper hole wall of sleeve pipe, start and drive oil cylinder, to promote or to pull sleeve pipe, just can realize the clamping of clamping head and loosen, just can realize the reducing to workpiece with this, and discharge bow and arrow.
Exert pressure to pipe end because such scheme adopts clamping head to tighten up, realize reducing, do not need tubing to rotate in mould, therefore to pipe geometry not requirement, the pipe end shrink mouth to bend pipe, straight tube can be realized.
Further, described driving oil cylinder is set to four, and is evenly distributed in frame; Oil cylinder can be made the active force of sleeve pipe evenly, prevent the concentrated wear between sleeve pipe and clamping head, and clamping head is stressed not only on the impact of Workpiece shaping.
Further, be arranged with on an axle by described tensioning spring inner ring, axle is provided with limit convex edge, to limit spring position, and be provided with blind hole on the slide block inwall of composition clamping head, described axle and spring are within blind hole, the other end is connected with a disk, and disk is positioned over clamping head inside center; This setting can realize good tension effects, is also convenient to install.
Further, the bottom of the slide block of described composition clamping head is provided with convex strangling, described frame is fluted with the slide block corresponding position of composition clamping head, and convex strangling becomes to be slidably connected with groove fit, and this is convex, and to strangle with the cross section of groove be trapezoidal.Tie rod linkage processing is simple, and the axial location of energy lock slider, anti-limited slip block produces deflection, or departs from frame, better realizes guide effect, and makes total compacter.
Further, clamping head top sliding block is set to eight pieces altogether, is more conducive to uniform force application, make workpiece necking forming effective, and also do not cause structure too complicated.

Fig. 3 is the frame plan of metal pipe material pipe end shrink mouth mould.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described in detail, so that the technical problem solved design of the present invention, the technical characteristic forming technical scheme and the technique effect that brings have further understands.But, it should be noted that to the explanation of these embodiments be schematic, do not form concrete restriction of the present invention.
From Fig. 1, Fig. 2 Fig. 3, metal pipe material pipe end shrink mouth mould is by sleeve pipe 1, and clamping head 2, tensioning spring 3, frame 4 and driving oil cylinder 5 are formed.
Sleeve pipe 1 center of metal pipe material pipe end shrink mouth mould of the present invention has conical through-hole, and be sleeve pipe conical through-hole, sleeve pipe 1 is set on clamping head 2, and sleeve pipe 1 periphery is provided with ring flange 11, and ring flange 11 is connected with the piston of described driving oil cylinder 5; Clamping head 2 comprises eight pieces of separate slider 21, is combined into taper, and coordinates with sleeve pipe conical through-hole, and when clamping head 2 is tapered, there is through hole its inside, and be clamping head through hole 22, the top of clamping head through hole 22 is tapered, is clamping head taper hole 221, for holding workpiece; Tensioning spring 3 is set on axle 31, axle 31 is provided with limit convex edge, to limit spring 3 position, and blind hole is provided with on slide block 21 inwall of composition clamping head 2, axle 31 and spring 3 are arranged within blind hole, and one end of axle 31 is fixedly connected with disk 32, and disk 32 is positioned in clamping head through hole, this is arranged to ensure that tensioning spring 3 is evenly exerted pressure to each block slide block 21 of clamping head 2, realizes closely cooperating of clamping head 2 and sleeve pipe 1; The bottom of slide block 21 of composition clamping head 2 is provided with convexly strangles 211, slide block 21 corresponding position of frame 4 and composition clamping head 2 also fluted 41, convexly strangle 211 and fit in be slidably connected with groove 41, this is convex, and to strangle 211 with the cross section of groove 41 be trapezoidal, makes slide block 21 only have the free degree of slip on groove 41; Drive oil cylinder 5 to be fixed in frame 4, be provided with four and be uniformly distributed; Start and drive oil cylinder 5, to pull or to promote sleeve pipe 1, just can realize the clamping of clamping head 2 and loosen.The end of place work piece 9, in clamping head taper hole 221, starts and drives oil cylinder 5, pull sleeve pipe 1, clamping head 2 is clamped, and applies circumferential pressure, just can realize workpiece 9 reducing to workpiece 9 end; Change and drive the oil-feed direction of oil cylinder 5, promote sleeve pipe, under the effect of tensioning spring 3, clamping head 2 open just desirable go out workpiece 9.
