Description

A kind of Balance mechanism bearing roller mold

Technical field

The utility model is related to a kind of cold extrusion die more particularly to a kind of Balance mechanism bearing roller molds.

Background technology

Since traditional moulds structure is relatively easy, leading to it, there are precision is low, service life is not high in use Problem.To prolong the service life, it is to do PVD coatings in die surface to lead method to be used currently on the market, but is being PVD Coating is to need to do the surface of all parts, is because mold core and outer ring are equipped with air discharge duct and formed in mould working region The difficult point of PVD is done, not only of high cost but also presence is made PVD coatings needs in the working region of mold and repeatedly squeezed, to mould Tool damage is very big, and process is various, and production efficiency is low, and causing clever sword, the cost is relatively high.

Utility model content

The purpose of this utility model is in order to solve the deficiencies in the prior art, in order to overcome disadvantages described above, the utility model Provide a kind of high speed pier forging machine bearing roller mold.

Technical solution：In order to solve problem above, the utility model provides a kind of Balance mechanism bearing roller mold, packet Include outer ring, the cavity of the outer ring sets cushion block, mold core one, mold core two successively from bottom to top, the cushion block, mold core one, in mold core Surface encloses an openings house room；The cushion block bottom sets pedestal；Stress is set between the mold core one, mold core two and outer ring Circle, respectively with outer ring, mold core one, mold core two are interference fitted the circle stress.The utility model is simple in structure, by by mold core First, mold core two no longer extrudes after being pressed into shrink ring, reduces repeatedly to squeeze and destroys mold core, increase die life, reduces work Sequence.

Equally distributed gas vent is equipped between the outer ring, mold core one and shrink ring.

The mold core one, the surfaces externally and internally of mold core two set PVD coatings.

Advantageous effect：The utility model compared with prior art, has the following advantages：

1. service life is long：By being pressed into shrink ring between outer ring in mold core one, mold core two, increasing the pre- of mold should Power reduces repeatedly to squeeze and destroys mold core, increases die life.

2. production cost reduces：

Description of the drawings

FIG. 1 is a schematic structural view of the utility model；

Wherein：1. outer ring, 2. cushion blocks, 3. mold cores one, 4. mold cores two, 5. shrink rings

Specific embodiment

The embodiment of the utility model is described in further detail with reference to the accompanying drawings and examples.Following embodiment For illustrating the utility model, but cannot be used for limiting the scope of the utility model." under ", "left", "right", " interior ", " outer ", The orientation or position relationship of the instructions such as " front end ", " rear end ", " head ", " tail portion " are to be closed based on orientation shown in the drawings or position System is for only for ease of description the utility model and simplifies description rather than instruction or imply that signified device or element are necessary With specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.In addition, Term " first ", " second ", " third " etc. are only used for description purpose, and it is not intended that instruction or hint relative importance.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected or integrally Connection；Can be mechanical connection or electrical connection；It can be directly connected, can also be indirectly connected by intermediary. For the ordinary skill in the art, it can understand that specific in the utility model of above-mentioned term containing with concrete condition Justice.

A kind of high speed pier forging machine bearing roller mold as shown in Figure 1, including outer ring 1, the cavity of the outer ring 1 is from lower past On set cushion block 2, mold core 1, mold core 24 successively, the cushion block 2, mold core 1,24 inner surface of mold core enclose an openings house Room；2 bottom of cushion block sets pedestal；Circle stress 5, the circle stress 5 are set between the mold core 1, mold core 24 and outer ring 1 Respectively with outer ring 1, mold core 1, mold core 24 are interference fitted；The mold core 1, mold core 24 are pressed into after shrink ring 5 no longer It extrudes；Equally distributed gas vent is equipped between the outer ring 1, mold core 1 and shrink ring 5；The mold core 1, mould The surfaces externally and internally of core 24 sets PVD coatings.

In use, cushion block 2 to be set on to the lower section of mold core 24, the pedestal set on cushion block 2 fixes 2 position of cushion block, makes its holding It is fitted close with mold core 24, material pier is entered the opening that cushion block 2, mold core 1,24 inner surface of mold core enclose by Balance mechanism It is bearing roller molding in accommodating chamber；Due to setting circle stress 5, the stress between the mold core 1, mold core 24 and outer ring 1 Respectively with outer ring 1, mold core 1, mold core 24 are interference fitted circle 5；The prestressing force of mold can be increased when material is pressed into accommodating chamber, It reduces and repeatedly squeezes the destruction caused by mold core, increase die life.

Those of ordinary skill in the art it should be appreciated that more than implementation be intended merely to illustrate that this practicality is new Type, and be not used as the restriction to the utility model, as long as in the spirit of the utility model, to the above Variation, modification will be all fallen in the Claims scope of the utility model.
