Abstract
The invention relates to auxiliary positioning equipment used for machining forged pieces like a bearing ring through a press open process, in particular to an adjustable positioning device for open punching of a press. The adjustable positioning device for open punching of the press is characterized by comprising a pressing cover (2), wherein a through hole is formed in the middle of the pressing cover (2), at least three installation holes (6) are distributed in the outer wall of the pressing cover (2) in the peripheral direction, a telescopic positioning rod is installed in each installation hole (6), and the two ends of each telescopic positioning rod extend into and out of the outer wall of the pressing cover (2) respectively, so that a forged piece to be machined is clamped in the middle. The adjustable positioning device for open punching of the press has the advantages of solving the problems and overcoming the quality defects of an original open punching process, improving and guaranteeing the quality of products, largely reducing the investment and adjustment frequency of moulds, enabling production and machining to be more convenient, largely improving the production efficiency, and being applicable to products of various specifications through the telescopic adjustment of a spring and a spare cap.
Description
Technical field
The auxiliary positioning equipment of using while the present invention relates to adopt the forging such as 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 at the punching station, generally be divided into backward extrusion punching and Open punching (also claiming free piercing), 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 the punching of blank material just, not there will be eccentric waste product after die adjustment puts in place, cut simultaneously end open width station blank material 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, need not too many replacing and 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 cause eccentric waste product, and then causes and cut end open width station and gross weight often occurs, and causes folding waste product.
Summary of the invention
The purpose of this invention 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, the gland outer wall is inside and outside can be clipped in the middle forging to be processed thereby stretch out respectively at the two ends of this telescopic backstay.
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 that wherein contacts with forging to be processed on positioning head is inclined-plane.
Wherein removably connect between positioning head and pull bar.
The invention has the beneficial effects as follows: 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, need not frequent replacing, has universal preferably.
Description of drawings
Accompanying drawing 1 is the structural representation of telescopic backstay in the present invention;
Accompanying drawing 2 is the structural representation of gland (2) in the present invention;
Accompanying drawing 3 is the use view of the present invention at the punching station;
Accompanying drawing 4 is that the B of Fig. 3 is to view.
The specific embodiment
As shown in Figure 1,2,3, 4, the present invention is a kind of forcing press Open punching adjustable positioning device, comprises gland 2, has through hole in the middle of this gland 2, along the circumferential direction is evenly equipped with 3-6 installing hole 6 on these gland 2 outer walls, is as shown in Figure 43.Telescopic backstay (abbreviation backstay) all is installed on each installing hole 6, gland 2 outer walls are inside and outside can be clipped in the middle forging to be processed thereby stretch out respectively at the two ends of this telescopic backstay.
Wherein telescopic backstay comprises a pull bar 3, this pull bar 3 inserts in described installing hole 6, dop 1 is installed and at same pull bar 3 ends of gland 2 outer pars intramuralis, positioning head 5 is installed on the pull bar 3 of gland 2 outer wall outsides, 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 that contacts 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 invention and using method are:
Positioning head 5 is connected with pull bar 3 with thread forms in the present invention, replacing while being convenient to positioning head 5 wearing and tearing, after potential head 5 undetermined is tightened, wear 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 Fig. 3,4, after all moulds are in place, with the initial workpiece product, adjust.Method of adjustment is for turning 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 that needs 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 be in suitable equidistant state, after specifically with material cake to be processed separately, putting into die cavity, all freedom is tangent with three backstays, 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.
