Abstract
The utility model discloses an undergauge mould, include: external mold and centre form, outer die sleeve is located the outside of centre form, the centre form includes a plurality of moulding -dies, a plurality of moulding -dies are formed with the holding chamber that holds the mould, its characterized in that, a plurality of moulding -dies are equipped with at least together along its outer surface distribution's slot the both ends of slot are equipped with spacing part the ditch inslot is equipped with the roll steel ball, the roll steel ball support to lean on in the internal surface of external mold, the technical scheme of the utility model can arrive the centre form with the even transmission of external mold applied pressure through the roll steel ball, the tubular product of processing can not the fold appear and keep the performance of tubular product the crack can not appear.
Description
Technical field
The utility model relates to machine-building stem reducing mould equipment, especially relates to a kind of stem reducing mould.
Background technology
Known molding type size reducing machine has retainer and the hydraulic cylinder in retainer, stem reducing mould to be in series.Stem reducing mould forms spatial accommodation by the mechanical sheet of two panels entity usually, will the tubing of undergauge be needed to put into, carries out undergauge by the drive of hydraulic cylinder to tubing.
Existing stem reducing mould is carrying out in the process of undergauge to tubing, the tubing of undergauge can be caused obvious at the position fold of depression, phase needs to carry out polishing or shaping operation after processing, also reduce efficiency while increasing operation, and existing stem reducing mould easily causes breaking of tubing when undergauge.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of stem reducing mould.
The purpose of this utility model will be achieved by the following technical programs: a kind of stem reducing mould, comprise: external mold and internal mold, described outer die casing is located at the outside of described internal mold, described internal mold comprises multiple pressing mold, described multiple pressing mold is formed with the accommodating cavity holding mould, it is characterized in that, described multiple pressing mold is provided with at least one groove distributed along its outer surface, limiting component is provided with at the two ends of described groove, in described groove, be provided with rolling steel ball, described rolling steel ball is resisted against the inner surface of described external mold.
Preferably, above-mentioned a kind of stem reducing mould, the inner surface of described external mold is provided with the stopper slot matched with described rolling steel ball.
Preferably, above-mentioned a kind of stem reducing mould, the tangent line at described groove place and the external diameter of described pressing mold tangent.
Outstanding effect of the present utility model is: arrange groove by the outer surface at internal mold, steel ball can be limited in groove and move, by the movement of steel ball, external mold can be applied to the pressure uniform of internal mold and be delivered to fast on internal mold, thus undergauge processing is carried out to the tubing in internal mold, the tubing obtained there will not be obvious folding line, and the performance of tubing still remains unchanged.The tangent line at groove place and the external diameter of pressing mold tangent, what can ensure the pressure maximum possible of steel ball transmission is delivered to pressing mold.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of stem reducing mould that the utility model embodiment provides.
Detailed description of the invention
As shown in Figure 1, a kind of stem reducing mould of the present embodiment, comprise: external mold 1 and internal mold 2, external mold 1 is sheathed on the outside of internal mold 2, and internal mold 2 comprises multiple pressing mold 201, and multiple pressing mold 201 is formed with the accommodating cavity 202 holding mould, multiple pressing mold 201 is provided with at least one groove 203 distributed along its outer surface, be provided with limiting component at the two ends of groove 203, be provided with rolling steel ball 204 in groove 203, rolling steel ball 204 is resisted against the inner surface of external mold 1.
Wherein, the diameter of external mold 1 is adjustable equally, and keeps corresponding with internal mold 2.
By arranging groove 203 at the outer surface of internal mold 2, rolling steel ball 204 can be limited in groove 203 mobile, by the movement of rolling steel ball 204, external mold 1 can be applied to the pressure uniform of internal mold 2 and be delivered on internal mold 2 fast, thus undergauge processing is carried out to the tubing in internal mold 2, the tubing obtained there will not be obvious folding line, and the performance of tubing still remains unchanged.
The inner surface of external mold 1 is provided with the stopper slot 101 matched with rolling steel ball 204.This stopper slot 101, for carrying out spacing to the rolling of rolling steel ball 204, prevents it from coming off from groove 203, causes mechanical movement fault.
The tangent line at groove 203 place and the external diameter of pressing mold 201 tangent, rolling steel ball 204 is provided with in groove 203, rolling steel ball 204 is for transmitting external mold 1 pair of internal mold 2 applied pressure, the pressure that rolling steel ball 204 receives can the most directly be delivered on internal mold 2 by tangent structure, thus processes tubing.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
