Description
Technical field
The present invention relates to a kind of necking die more particularly to a kind of metal pipe material pipe end shrink mouth devices.
Background technique
Necking is realized to tubing at present, pressure receipts are mainly carried out using machine for shrinking or particular manufacturing craft carries out punching press, draw owner
Will be by the way of spinning, spinning is that plate or hollow blank are fixed on the mold of spinning machine, in blank with machine tool chief axis
While rotation, with spinning roller or stick is caught up with to stress on blank, is allowed to generate the plastic deformation of part.Feed motion and base in spinning roller
Under the rotary motion collective effect of material, local plastic deformation is set to expand to all surfaces of blank step by step, and be tightly attached to mould
Tool, completes the rotary pressing processing of part.Spinning is a kind of special manufacturing process.Various shape rotation can be completed with spin-on process
The techniques such as drawing, flange, necking, bulging and the crimping of body；When being related to some bend pipes, machine for shrinking then can not achieve clamping, make
Bend pipe rotation；And particular manufacturing craft then needs for tubing to be placed on upper mold or lower die, realizes pipe by the mutual punching press of upper and lower mould
The plastic deformation of material, so machine for shrinking or particular manufacturing craft are mainly chiefly used in straight tube processing, it is larger to the limitation of pipe geometry.
Chinese patent CN201320293282.X discloses a kind of metal tube necking device, includes disk spring, fixation
Outer ring and compression inner ring, the principle that internal diameter becomes smaller when being compressed using disk spring will fix outer ring and compress inner ring through screw thread
Connection rotates fixed outer ring or compresses inner ring, deforms disc spring, and the internal diameter of disc spring becomes smaller in deformation process, squeezes metal tube, then
Metal tube is drawn with puller system, metal tube is made to attenuate；This device simplifies necking process, but due to still needing to pull tubing, for
Non- straight tube is still unfavorable for tubing clamping.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of tubing is fixed, and to pipe geometry there is no limit contracting
Mouth mold tool.
In order to solve the above problem, the present invention provides a kind of metal pipe material pipe end shrink mouth devices, comprising: including rack, folder
Hold head, disk spring and clamp sleeve；Rack is equipped with fixed outer ring, and to support clamping head, it is logical that fixed outer ring is equipped with one
Hole is placed in hole for workpiece；Clamping head is cylindrical, is divided into multiple independent sectors, is set in the fixation outer ring of rack, clamping
When head is combined into complete cylinder, it is centrally formed through-hole, is clamping head through-hole, clamping head the front end of the through hole is tapered, is clamp cone
Hole, clamping taper hole are communicated with workpiece merging hole；Clamping head is provided with tensioning spring, and tensioning spring can be such that clamping head has outward
Tensile force, and keep clamping force uniform；The disk spring is nested with outside clamping head, and clamp sleeve acts on disk spring.
After workpiece end is placed in clamping taper hole by workpiece merging hole, applies pressure to clamp sleeve, make dish
Spring is deformed, then disk spring inner radii becomes smaller, and clamping head is promoted to tighten to center, makes the clamping taper hole half of clamping head
Diameter also constantly reduces, then clamping head circumferentially generates pressure to workpiece, and workpiece is made to realize necking；After completing necking, clamping sleeve is shed
The pressure of cylinder, butterfly spring revert to nature, then clamping head opens under the action of tensioning spring, just unclamps workpiece；
Workpiece is removed, can be processed next time.
It is tightened using clamping head to pipe end and is pressed due to above scheme, tubing is fixed, therefore does not have to pipe geometry
It is required that and under the action of tensioning spring can be achieved clamping head stress more evenly, exert a force it is more stable, avoid force unevenness to pipe
Material damages.
Further, set multiple for the disk spring, and between there is retaining ring to separate；Can make clamping head have it is multiple by
Force makes clamping head stress more evenly, shrinks more stable.
Further, the clamping head is processed, when clamping head being made to combine complete cylinder, the clamping head that is centrally formed
Through-hole tail end is also tapered, to be tensioned taper hole, a frustum is arranged in tensioning taper hole, by the tensioning spring in this frustum and machine
Between frame wall, the tensioning to clamping head is realized；This tensioning mode structure is simple, and easy for installation, tension effects are good.
Further, the filling elastic material between the fixation outer ring inner circumferential and clamping head periphery；So that clamping head exists
In deformation process, center is constant.
Further, clamping head is divided into eight independent sectors, is more advantageous to uniform force application, make workpiece necking forming effect
It is good, and do not cause structure excessively complicated yet.
Detailed description of the invention
Fig. 1 is metal pipe material pipe end shrink mouth device cross-sectional view；
Fig. 2 is metal pipe material pipe end shrink mouth device left view.
Specific embodiment
A specific embodiment of the invention is further described in detail below in conjunction with attached drawing, so as to design of the invention
The technical issues of solved, the technical characteristic for constituting technical solution and bring technical effect have further understanding.But
It should be noted that being schematically, not constitute to specific restriction of the invention to the explanation of these embodiments.
As seen from Figure 1, Figure 2, metal pipe material pipe end shrink mouth device is by rack 1, clamping head 2, disk spring 3 and clamp sleeve
4 are constituted.
The rack 1 of metal pipe material pipe end shrink mouth device of the present invention is equipped with fixed outer ring 11, to support clamping head 2 and dish
The retaining ring 31 of shape spring 3, fixes on outer ring 11 and is provided with a through-hole, is placed in hole for workpiece；Clamping head 2 is divided into eight independent parts
Point, it is placed in fixed outer ring 11, is nested in 2 periphery of clamping head there are two disk spring 3, disk spring 3 is separated by retaining ring 31, makes
2 stress of clamping head is more evenly；When clamping head 2 is combined into complete cylinder, there is through-hole at center, is clamping head through-hole, and clamping head is logical
Hole rear and front end is tapered, and wherein front end is clamping taper hole, and rear end is tensioning taper hole；It clamps taper hole and is placed in hole phase with workpiece
It is logical, so that the end of workpiece 8 is placed into clamping taper hole, realizes necking；Be tensioned taper hole in be arranged frustum 51, frustum 51 with
It is provided with tensioning spring 5 between chassis wall, can make clamping head that there is outward power；The inner circumferential and clamping head of fixed outer ring 31
Resilient material 6 is filled between 2 peripheries, elastic material 6 uses rubber；Elastic material 6 is to guarantee clamping head 2 in contraction process
In, center is constant；Clamp sleeve 4 acts on disk spring 3, when applying pressure to clamp sleeve 4, can make dish-shaped bullet
Spring 3 deforms, and inner ring diameter becomes smaller, and race diameter becomes larger, and makes clamping head 2 to central reduction, then is placed in clamping taper hole
The circumferential extruding by clamping head in the end of workpiece 8, makes tubing generate plastic deformation, realizes tubing necking；After the completion of necking, unload
Except clamp sleeve 4 is to the pressure of butterfly spring 3, then butterfly spring 3 is restored to nature, and clamping head 2 is also in tensioning spring 5
It is flared out under effect, then clamps taper hole and discharge clamping to workpiece 8, remove the processing that can then carry out next workpiece after workpiece 8.
