Abstract

The utility model relates to a processing mould of a conical bearing maintainer, in particular to an unloading, stretching and location hole punching trimming-free integrated mould for the cone maintainer. The unloading, stretching and location hole punching trimming-free integrated mould for the cone maintainer comprises an upper punching mould and a lower punching mould. The upper mould is internally provided with an inner material return block which is internally moveably sleeved with a central hole punch and a location hole punch. Knockout plates are arranged at the upper ends of the central hole punch and the location hole punch. A stretching die is sleeved outside the inner material return block. A stretching terrace die is arranged in the center of the lower mould. A blank holder is arranged in a position on the lower mould corresponding to the stretching terrace die. The step of turning the end face of the opening by a lathe is cancelled, the product quality is stable and reliable, and the product yield is improved. When stretched to 80% in place, the punch which punches the location hole works to punch the location hole. Compared with previous single step for producing the bearing maintainer, two punch presses and a lathe are cancelled, so that the labor of workers is saved, and the work efficiency is improved.

Description

The blanking of circular cone retainer stretches and exempts from car limit integrated mould towards locating hole
Technical field
The utility model relates to a kind of conical bearing retainer processing mold, specifically is that a kind of circular cone retainer blanking stretching is exempted from car limit integrated mould towards locating hole.
Background technology
Existing market is produced the general processing of seven types of retainers by blanking, stretching, form towards three process such as locating holes.Adding man-hour, because retainer receives material ductility and linear direction inconsistent when stretching, the oral area of the retainer that processes just rises and falls, and size is inconsistent, and height error can reach more than the 1mm, therefore also needs this procedure of machined into oral area.The retainer cost that so processes is high, and efficient is low, inapplicable existing enterprise development demand.
Summary of the invention
The purpose of the utility model is exactly for solving the problem that prior art exists, exempt from car limit integrated mould and designed a kind of circular cone retainer blanking stretching towards locating hole, improving working (machining) efficiency and crudy.
The technical scheme of the utility model is: a kind of circular cone retainer blanking stretches and exempts from car limit integrated mould towards locating hole; Include punching press patrix and punching press counterdie; Material returned piece in being provided with in the said patrix is movably installed with centre bore drift and locating hole drift in the interior material returned piece; The upper end of centre bore drift and locating hole drift is provided with knockout plate; The outside of interior material returned piece is set with the stretching die; The center of said counterdie is provided with stretching convex die, and position corresponding with the stretching die on the counterdie is provided with blank holder.
The diameter of said centre bore drift is 14mm, and the diameter of locating hole drift is 5mm.
The beneficial effect of the utility model is: because the blanking stretching is integrated towards the locating hole three process, utilize the stretching principle, blank holder compresses woolen cloth, at the uniform velocity stretches, and guarantees that product oral area end face is concordant, and flatness reaches the product drawing requirement in 0.1mm.Saved this operation of lathe turning oral area end face, stable and reliable product quality has improved the qualification rate of product.Put in place 80% o'clock in stretching, the drift work of stamping-out locating hole, stamping-out goes out locating hole.Two punch presses and a chassis bed have been saved in single operation production before the bearing cage of producing is like this compared, save workman's work, have improved operating efficiency.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Wherein, 1. patrix, 2. counterdie, 3. centre bore drift, 4. locating hole drift, 5. knockout plate, 6. stretching die, 7, interior material returned piece, 8, blank holder, 9, stretching convex die, 10, product.
The specific embodiment:
In order to understand the utility model better, come the embodiment of illustrated in detail the utility model below in conjunction with accompanying drawing.
Specific embodiment: as shown in Figure 1; A kind of circular cone retainer blanking stretches and exempts from car limit integrated mould towards locating hole; Include punching press patrix 1 and punching press counterdie 2, material returned piece 7 in being provided with in the said patrix 1 is movably installed with centre bore drift 3 and locating hole drift 4 in the interior material returned piece 7; The upper end of centre bore drift 3 and locating hole drift 4 is provided with knockout plate 5; The outside of interior material returned piece 7 is set with stretching die 6; The center of said counterdie 2 is provided with stretching convex die 9, is provided with blank holder 8 with stretching die 6 corresponding positions on the counterdie 2.The diameter of said centre bore drift 3 is 14mm, and the diameter of locating hole drift 4 is 5mm.
The utility model can pass through existing techniques in realizing without the technical characterictic of describing, and repeats no more at this.Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
