Abstract
The invention relates to a step extruding die for a bearing shim. The step extruding die comprises a lower die holder and an upper die plate, wherein a concave die is arranged on the lower die holder; a base plate and a punch fixing plate are sequentially arranged below the upper die plate; a die handle is mounted on the upper die plate; a punch is mounted on the punch fixing plate; an unloading device is arranged on the punch fixing plate; the concave die is provided with a positioning device which comprises a positioning pin; a spring is arranged below the positioning pin; a set screw is arranged below the spring; the head of the positioning pin extends out of the concave die; the unloading device comprises an unloading plate and a spring mounted between the unloading plate and the punch fixing plate; the punch fixing plate is provided with a guide pillar; and the guide pillar is matched with a hole on the concave die. By adopting the structure, the shortcomings of the traditional turning processing, such as unstable product quality, relatively high rejection rate and low production efficiency, are overcome, the product quality and efficiency are improved, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of mould of field of machining, especially relate to a kind of machining high-precision and high efficiency bearing shim and squeeze the step mould.
Background technology
At present, in the manufacturing procedure of in the past bearing shim, what producer adopted usually is the processing method of car endoporus, step, but because product thickness thin (having only 1mm), endoporus, external diameter are little, and Vehicle Processing is bad carries out clamping and location to product, cause its dimensioned precision not high, working (machining) efficiency is extremely slow, can not adapt to batch process, has increased manufacturing cost.Shortcomings such as the producer that has adopts mould to process, but all can there be the unstable product quality that processes in most this mould, and service life is short.
Summary of the invention
Technical problem to be solved by this invention provides a kind of bearing shim and squeezes the step mould, and it replaces original Vehicle Processing operation, can solve problems such as unstable product quality that former processing method and mould exist and efficient are not high.
The present invention solves the technical scheme that its technical problem takes: a kind of bearing shim squeezes the step mould, comprise die shoe and cope match-plate pattern, die shoe is provided with die, the below of cope match-plate pattern is provided with backing plate and drift fixed head successively, die shank is installed on the cope match-plate pattern, drift is installed on the drift fixed head, the drift fixed head is provided with device for discharging, die is provided with positioner, described positioner comprises alignment pin, the below of alignment pin is provided with spring, and the spring below is provided with holding screw, and the head of alignment pin stretches out die.
For convenience the workman takes out product and leveling product, described device for discharging comprise stripper and be installed on stripper and the drift fixed head between spring.
In order to improve precision in punching press, described drift fixed head is provided with guide pillar, and the hole on guide pillar and the die is used.
The invention has the beneficial effects as follows: adopted after the said structure, overcome the unstable product quality that exists in the original employing car system processing, percent defective is higher, and the shortcoming that production efficiency is low has improved product quality and efficient, has reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the blank drawing of product;
Fig. 3 is the part drawing of product.
Among the figure: 1, die shank 2, cope match-plate pattern 3, backing plate 4, drift fixed head 5, drift 6,11, spring 7, stripper 8, die 9, die shoe 10, holding screw 12, alignment pin 13, guide pillar
The specific embodiment
A kind of as shown in Figure 1 bearing shim squeezes the step mould, comprise die shoe 9 and cope match-plate pattern 2, die shoe 9 is provided with die 8, the below of cope match-plate pattern 2 is provided with backing plate 3 and drift fixed head 4 successively, die shank 1 is installed on the cope match-plate pattern 2, drift 5 is installed on the drift fixed head 4, drift fixed head 4 is provided with device for discharging, die 8 is provided with positioner, described positioner comprises 3 alignment pins 12, the below of alignment pin 12 is provided with spring 11, and spring 11 belows are provided with holding screw 10, and the head of alignment pin 12 stretches out die 8; Described device for discharging comprise stripper 7 and be installed on stripper 7 and drift fixed head 4 between spring 6; Described drift fixed head 4 is provided with guide pillar 13, and the hole on guide pillar 13 and the die 8 is used.
During work under the slide block effect of forcing press, the part of the upper die is descending under the guiding of guide pillar, stripper 7 compresses the spacing product (as shown in Figure 2) of alignment pin 12 under the effect of spring 6, while drift 5 contact products, when slide block to after bottom dead center, the extruding that drift 5 is finished blank reaches technological requirement (as shown in Figure 3).When slide block was got back to top dead-centre, product stripping was finished a working cycles under the effect of stripper 7, waits for next working cycles.Stripper 7 plays the effect of discharging and leveling at work, and product has also obtained good flatness when obtaining the extruding size.
The foregoing description does not limit the present invention in any way all employings and is equal to and replaces or technical scheme that the mode of equivalence conversion obtains all drops in protection scope of the present invention.
