Description
Technical field
The utility model relates to machined field, is specifically related to a kind of drift for roller cold holder.
Background technology
Cold headers make roller or other products with cold-heading method, is widely used in machined manufacturing industry.Drift, as a vitals of cold headers, play a major role, and the installation accuracy of drift determines the quality of product in complete machine.And the drift body of rod is consumable accessory, in use need frequent replacing, and the installation accuracy of the drift body of rod and mould endoporus is high, not easily install in actual machining process, for realizing the installation of the drift body of rod and mould, often need to make to have larger gap between the drift body of rod and mould endoporus, such setting can cause the drift body of rod in the course of the work again, there is skew radially in the body of rod, reduce the quality of product in mould endoporus.
Utility model content
The utility model be overcome existing cold headers exist because of the drift body of rod and mould quality of fit high, the drift body of rod as consumable accessory is not easily dismantled, is installed, and because the drift body of rod is because occurring the problem of radial deflection in a mold, a kind of drift for roller cold holder adding sealing ring type is provided, plunger rod in this drift and mould no-float, and easily change plunger rod.
The utility model for the technical scheme realizing the problems referred to above and adopt is: a kind of drift for roller cold holder, comprise plunger rod, outer die casing, cushion block and the clamping pad for holding out against cushion block, plunger rod is arranged in the through hole at outer die casing center, the punching press end of plunger rod stretches out from one end of outer die casing, the other end of plunger rod is connected with the cushion block be located in described through hole, the other end of outer die casing forms shutoff end by the clamping pad be fixedly connected with it, described plunger rod coordinates with via clearance, and through-hole wall is provided with multiple annular groove, be equipped with ring in each annular groove and be located at sealing ring on plunger rod outer peripheral face.
Described cushion block and clamping pad are solid cylinder structure, and one end of clamping pad is stretched out from outer die casing, and this external part of clamping pad is provided with the flange be connected with outer die casing by screw.Wherein, cushion block is identical with the external diameter of clamping pad, and the two all coordinates with described via clearance.
Described clamping pad is along its central shaft to being provided with air-vent.
Described plunger rod is formed by connecting by truncated cone linkage section by the cylindrical bar that two sections of diameter are different, and the enlarged diameter section of plunger rod is connected with cushion block by another truncated cone linkage section, and the reduced diameter section of plunger rod stretches out outer die casing.
The beneficial effects of the utility model: 1, outer die casing central through hole is provided with multiple annular groove, be provided with ring in annular groove and be located at sealing ring on plunger rod outer peripheral face, the drift adding sealing ring type can avoid drift operationally, the radial deflection of plunger rod in outer die casing through hole, on the one hand, plunger rod is consumable accessory, add the design of sealing ring type, can avoid because offseting the wearing and tearing causing plunger rod, and then avoid becoming wide arc gap coordinate because wearing and tearing causing plunger rod and outer die casing through hole to be coordinated from small―gap suture, improve the service life of plunger rod; On the other hand, ensure that the quality of product.
2, the installation accuracy of plunger rod and outer die casing through hole is higher, and in use need frequent replacing as the plunger rod of consumable accessory, existing plunger rod coordinates with the small―gap suture of outer die casing through hole not easily installs realization, the design adding sealing ring type suitably can increase fit clearance therebetween, on easy-to-install basis, the radial deflection of plunger rod can be avoided again.
3, drift is divided into plunger rod and the outer die casing with its matched in clearance by the utility model, after plunger rod wearing and tearing, is easy to change, makes plunger rod remain on high accuracy state always; The cushion block set up and clamping pad, can cushion the reaction force of plunger rod when punching press, extends the service life of plunger rod.

Detailed description of the invention
A kind of drift for roller cold holder, as shown in Figure 1, comprise plunger rod 1, outer die casing 2, cushion block 3 and clamping pad 4, plunger rod 1 small―gap suture is equipped with in the through hole along outer die casing 2 center, one end of plunger rod 1 is punching press end, the other end is link, and its punching press end stretches out from one end of outer die casing 2, and link is connected with the cushion block 3 being located at outer die casing 2 central through hole; The other end of outer die casing 2 forms shutoff end by the clamping pad 4 be fixedly connected with it, one end of clamping pad 4 is stretched out from outer die casing 2, and this external part of clamping pad 4 is provided with the flange be connected with outer die casing 2 by multiple screw 7, by the spacing between adjustment flange and outer die casing 2 end, realize the effect that clamping pad 4 holds out against cushion block 3.Wherein, described plunger rod 1 coordinates with the through hole small―gap suture of outer die casing 2, and this through-hole wall is provided with multiple annular groove 5 relative to the position of plunger rod 1, is equipped with ring and is located at sealing ring 6 on plunger rod 1 outer peripheral face in each annular groove 5.
The utility model, drift is divided into outer die casing 2 and can adjusts the plunger rod 1 of position, plunger rod 1 is formed by connecting by truncated cone linkage section by the cylindrical bar that two sections of diameter are different, the enlarged diameter section of plunger rod 1 is connected with cushion block 3 by another truncated cone linkage section, and the reduced diameter section of plunger rod 1 stretches out outer die casing 2.In use for some time, the plunger rod 1 of wearing and tearing can adjust the position of plunger rod 1 punching press end by cushion block 3 and clamping pad 4, or directly change plunger rod 1, make drift remain on high accuracy state always, and the impulsive force of cushion block 3 when can cushion plunger rod 1 punching press, this impulsive force can also be made to disperse, avoid outer die casing 2 stress to concentrate and occur crackle.In the utility model, clamping pad 4 is along its central shaft to the air-vent 8 being provided with through clamping pad 4 two ends.
Further, cushion block 3 and clamping pad 4 are solid cylinder structure, and cushion block 3 is identical with the external diameter of clamping pad 4, and the two all coordinates with the via clearance of outer die casing 2.
