Abstract

The invention relates to an automobile part processing die, and particularly relates to a high-precision diaphragm pressure quenching die. The pressure quenching die comprises a base and a die shank; a lower die and a core rod are arranged on the base; an upper die is arranged on the die shank; the upper die and the lower die are arranged coaxially and oppositely; and diaphragm cavities are formed in opposite surfaces of the upper die and the lower die. The pressure quenching die is characterized in that a guiding and limiting ring is fixedly arranged on the outer wall of the lower die, the guiding and limiting ring is upwards extended until the height of the guiding and limiting ring is over 1/3 of the height of the upper die, and the guiding and limiting ring is provided with a plurality of oil drainage holes opposite to the diaphragm cavities. The die solves the problems that the ellipticity of a diaphragm is qualified but the angle discreteness is high because the upper and lower dies are centered and positioned inaccurately and the diameter discreteness of a central hole is high after stamping diaphragm separated fingers are formed and the runout seriously exceeds the standard because oil enters into the core rod in the conventional diaphragm pressure quenching die; and the die is mainly used for processing the diaphragm in an automobile clutch.

Description

A kind of high precision membranes is pressed the mould of quenching
(i) technical field: the present invention relates to the improvement technology of automobile component processing mold, especially a kind of high precision membranes is pressed the mould of quenching.
(ii) background technology: at present, in the clutch coupling industry production, the pressing diaphragm mould of quenching is one of visual plant of producing on diaphragm, the existing pressing diaphragm mould of quenching includes base and die shank, counterdie and plug are installed on base, patrix is installed on die shank, the coaxial positioned opposite of upper and lower mould, and have the diaphragm die cavity on the opposite face of upper and lower mould.Because diaphragm is thin-walled frustum structure, existing pressure is quenched mould due to discrete large at punching press separation finger moulding rear center bore dia, in pressure is quenched process, is difficult to carry out positioned centrally with plug, very easily causes that the diaphragm ovality is defective and angle is discrete large; On the other hand, the existing pressure mould of quenching is to offer the oil supply hole oil-feed on plug, can make like this diaphragm separation finger outer end can not be fully and the plug laminating, easily causes end to jump severe overweight, is arranged on clutch coupling, will affect its serviceability.
(iii) summary of the invention: purpose of the present invention is exactly to overcome the existing pressing diaphragm the problems referred to above that mould exists of quenching, and provides a kind of high precision membranes to press the mould of quenching.
Concrete scheme of the present invention is improved for the existing pressing diaphragm mould of quenching, it includes base and die shank, counterdie and plug are installed on base, patrix is installed on die shank, the coaxial positioned opposite of upper and lower mould, and have the diaphragm die cavity on the opposite face of upper and lower mould, it is characterized in that: the outer wall at counterdie fixedly is equipped with a guide and limit circle, the height of guide and limit circle extends upwardly to the patrix height more than 1/3, and relative diaphragm cavity positions has several outages on the guide and limit circle.
For convenience of the importing of patrix, the upper port of the circle of guide and limit described in the present invention is bell mouth shape, to facilitate the importing of patrix.
In the present invention, be to have some oil-feed tanks to be communicated with the diaphragm die cavity at the counterdie top.And the twice that the oil-feed tank number on described counterdie is the outage number on the guide and limit circle.
The present invention, owing to having increased the guide and limit circle, both can guarantee the location of diaphragm, can be used for again upper and lower mould centering, makes and presses accurate positioning in the process of quenching, thereby overcome the pressing diaphragm defective and discrete large problem of angle of rear ovality of quenching.Oil-feed tank in the present invention is directly opened on counterdie on the other hand, has cancelled the oil-feed oil duct on the plug, therefore in pressure is quenched process, separates finger tip and is pushed down fully, and end is jumped and is effectively controlled; Owing to adopting the counterdie oil-feed, can provide larger oil inlet quantity in addition, quenching hardness is effectively guaranteed.
The present invention is simple in structure, easy to use, reliable operation, and processing precision of products is high.
(iv) accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the main sectional view of guide and limit circle in the present invention;
Fig. 3 is the main sectional view of counterdie in the present invention;
Fig. 4 is the vertical view of counterdie in the present invention.
In figure: 1-die shank, 2-plug, 3-patrix, 4-diaphragm die cavity, 5-counterdie, 6-base, 7-oil-feed tank, 8-bolt, 9-bolt, 10-guide and limit circle, 11-bolt, 12-outage, 13-hydraucone.
(v) embodiment:
Referring to Fig. 1, base 6 and die shank 1 have been the present invention includes, on base 6, adopt bolt 9 and 8 that counterdie 5 and plug 2 are installed, patrix 3 is installed on die shank 1, on, counterdie 3 and 5 coaxial positioned opposite, and upper, have diaphragm die cavity 4 on counterdie 3 and 5 opposite face, particularly: the outer wall at counterdie 5 adopts bolt 11 that a guide and limit circle 10 fixedly is housed, the 1/2(that the height of guide and limit circle 10 extends upwardly to patrix 3 height is generally getting final product more than 1/3, to guarantee that guiding and location need), and diaphragm die cavity 4 positions have 30 outages 12 relatively on guide and limit circle 10.
The upper port of the circle of guide and limit described in the present embodiment 10 is hydraucone 13 shapes, with the importing (referring to Fig. 2) that facilitates patrix 3.
In the present embodiment, be to have 60 oil-feed tanks 7 to be communicated with diaphragm die cavity 4, (referring to Fig. 3,4) at counterdie 5 tops.

Claims (4)
