Abstract
The invention discloses a reducing mold which comprises an outer mold and an inner mold. The inner mold is sleeved with the outer mold. The inner mold comprises a plurality of pressing molds. A containing cavity for containing the mold is formed in the pressing molds. The reducing mold is characterized in that the pressing molds are provided with at least one groove distributed along the outer surfaces of the pressing molds, limiting components are arranged at the two ends of the groove, and rolling steel balls are arranged in the groove and abut against the inner surface of the outer mold. According to the technical scheme, pressure exerted by the outer mold can be evenly transferred to the inner mold through the rolling steel balls, no crease is produced on a machined pipe, and the performance of the pipe is kept free of cracking.
Description
Technical field
The present invention relates to machine-building stem reducing mould equipment, especially relate 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 object of the invention is to propose a kind of stem reducing mould.
Object of the present invention 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 invention 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 the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of stem reducing mould that the embodiment of the present invention 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, and 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.In groove 203, be provided with rolling steel ball 204, rolling steel ball 204 is for transmitting external mold 1 pair of internal mold 2 applied pressure, and 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 present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
