Abstract

The utility model relates to an auxiliary locating device which is used when a press machine open-type technology is adopted to machine forged pieces such as bearing ferrules, in particular to an adjustable locating device for press machine open-type punching. The adjustable locating device is characterized in that the adjustable locating device comprises a gland (2), a through hole is formed in the middle of the gland (2), at least three mounting holes (6) are evenly formed in the outer wall of the gland (2) in the circumferential direction, a telescopic locating rod is installed inside each mounting hole (6), and the two ends of each telescopic locating rod stretch out of the inner portion of the outer wall of the gland (2) and the outer portion of the outer wall of the gland (2) respectively so that a forged piece to be machined can be clamped in the middle. The adjustable locating device for press machine open-type punching has the advantages that various quality defects and problems existing in existing open-type punching are overcome and solved, the product quality is improved and guaranteed, die investment and adjustment are greatly reduced, production and machining are made to be more convenient, the production efficiency is greatly improved, and through telescopic adjustment of springs and spare caps, the locating device can be used for various products of different specifications universally.

Description

Forcing press Open punching adjustable positioning device
Technical field
The auxiliary positioning equipment of using when the utility model relates to forging such as adopting forcing press open type processes bearing ring, especially a kind of forcing press Open punching adjustable positioning device.
Background technology
In bearing industry, in the forcing press technique of processing lasso forging, be all generally to adopt press forging race blank at present, then calendering forming on staving press, form processing line.Forcing press is when the forging collar blank, the general layout that adopts jumping-up, punching, cuts three stations of end open width, and generally be divided into backward extrusion punching and Open punching (also claiming free piercing) at the punching station, these two kinds of punching modes cut both ways on process characteristic, backward extrusion punching advantage is due to the effect that mould is arranged, and after die adjustment puts in place, the punching of blank material just, not there will be eccentric waste product, cut end open width station blank material simultaneously and also not there will be gross weight, and cause folding waste product.Shortcoming is that the mould input is high, changes adjustment loaded down with trivial details.Open punching antithesis, it is advantageous that the mould less investment, without too many replacing, adjusts.Major defect is owing to being free piercing, and the operator mainly by feel and experience, can not just effectively rush while causing the punching of blank material when operation, easily causes eccentric waste product, and then causes and cut end open width station and gross weight often occurs, and causes folding waste product.
The utility model content
The purpose of this utility model is to provide a kind of forcing press Open punching adjustable positioning device, can avoid problem in original Open punching technique, the problem includes: defect and problem after using this positioner.
A kind of forcing press Open punching adjustable positioning device, its special feature is: comprise gland, have through hole in the middle of this gland, along the circumferential direction be evenly equipped with at least 3 installing holes on this gland outer wall, telescopic backstay all is installed on each installing hole, thereby stretch out respectively at the two ends of this telescopic backstay, the gland outer wall is inside and outside can be clipped in the middle forging to be processed.
Wherein telescopic backstay comprises a pull bar, this pull bar inserts in described installing hole, dop is installed on the pull bar of gland outer wall outside and outside gland the same pull bar end of pars intramuralis positioning head is installed, and between this positioning head and gland outer wall, spring is installed.
Wherein dop adopts back of the body cap or nut.
Its medi-spring adopts Y type spring.
The one side wherein contacted with forging to be processed on positioning head is inclined-plane.
Wherein between positioning head and pull bar, removably connect.
The beneficial effects of the utility model are: after 1, this positioner uses, preferably resolve many mass defect and problem that original Open punching exists, effectively improve and guaranteed product quality.2, greatly reduced mould and dropped into and adjust, made production and processing become more convenient, production efficiency has had raising by a relatively large margin.3, this positioner is by the flexible adjustment of spring, standby cap, and a covering device can meet the general of multiple different product specification, without frequent replacing, has universal preferably.
The accompanying drawing explanation
The structural representation that accompanying drawing 1 is telescopic backstay in the utility model;
The structural representation that accompanying drawing 2 is gland in the utility model (2);
Accompanying drawing 3 is the use view of the utility model at the punching station;
The B that accompanying drawing 4 is Fig. 3 is to view.
The specific embodiment
As shown in Figure 1,2,3, 4, the utility model is a kind of forcing press Open punching adjustable positioning device, comprises gland 2, in the middle of this gland 2, has through hole, along the circumferential direction be evenly equipped with 3-6 installing hole 6 on these gland 2 outer walls, be as shown in Figure 43.Telescopic backstay (abbreviation backstay) all is installed on each installing hole 6, thereby stretch out respectively at the two ends of this telescopic backstay, gland 2 outer walls are inside and outside can be clipped in the middle forging to be processed.
Wherein telescopic backstay comprises a pull bar 3, this pull bar 3 inserts in described installing hole 6, dop 1 is installed on the pull bar 3 of gland 2 outer wall outsides and at same pull bar 3 ends of gland 2 outer pars intramuralis, positioning head 5 is installed, and between this positioning head 5 and gland 2 outer walls, spring 4 is installed, dop 1 adopts back of the body cap or nut, and spring 4 adopts Y type spring.The one side contacted with forging to be processed on positioning head 5 in addition is inclined-plane, and main purpose is that after being convenient to the placement of processed product and punching processing and completing, product is taken out.Removably connect between positioning head 5 and pull bar 3, for example be threaded, thereby be convenient to change the positioning head 5 of wearing and tearing.
Operation principle of the present utility model and using method are:
In the utility model, positioning head 5 is connected with pull bar 3 with thread forms, replacing while being convenient to positioning head 5 wearing and tearing after potential head 5 undetermined is tightened, is worn bifurcation type spring 4 on pull bar 3, then be through respectively in three installing holes 6 of gland 2, and use respectively standby cap tentatively fixing at pull bar 3 other ends.
As shown in Figure 3,4, after all moulds are in place, with the initial workpiece product, adjusted.Method of adjustment is for to turn the standby cap on each backstay with spanner, rely on the flexible of backstay upper spring 4, make the backstay of three horizontal circumference uniform distributions of each station, reach the equidistant state needed perpendicular to the direction of theoretical tangent line separately, spatially form the die cavity of placing forging blank material to be processed.And two stations separately three backstays in suitable equidistant state, after specifically with material cake to be processed separately, putting into die cavity, with three backstays, all freedom is tangent, or be slightly less than material cake cylindrical to be processed 1~1.5mm and be advisable, just can realize the effective location of two station blank material and punching.
In the production and application process, blank material cylindrical than small deformation can make two stations separately the spring 4 of three backstays be subject to synchronous trace compression, avoid and alleviated infringement and the impact of blank material cake to positioner, simultaneously due to the telescopic action that spring 4 is arranged, blank material cake complete processing remove after, backstay can return back to original state, and then iterative cycles, forms continuous productive process.
