Abstract
The utility model discloses a forcedly pressing die for a membrane, which comprises a membrane handle, a top die, a bottom die and a lower base. The forcedly pressing die for the membrane is characterized in that a matched die central spindle is arranged between the top die and the bottom die. Because the matched die central spindle is added in the die, the angle difference value of a forcedly-pressed product is generally consistent with the angle difference value of a product which is not forcedly pressed; and angles of same batch of membranes differ for 6-8 minutes, the angle consistency of a product is improved, and the manufacturing procedure quality of membrane pressure is improved. The forcedly pressing die for the membrane performs great action on improving the heat treatment processing quality, the consistency of membrane pressure is improved, and the difference value of the pressures of a peak point, a valley point and a planishing point is less than 250N. The forcedly pressing die for the membrane performs active action on improving the percent of pass of assembly fitting and lowering product drilling and removing rate.
Description
Technical field
The utility model relates to diaphragm processing, specifically is that a kind of diaphragm is suppressed mould.
Background technology
In the production of diaphragm spring, every leaf spring all need be suppressed processing, to guarantee spring free height dimensional stabilizing, eliminates spring and uses early stage elastic force decay, guarantees the spring reliable operation.Existingly suppress the center that the position will lean on staff's experience adjustment to suppress when suppressing mould dress mould, there are artifical influence factor and waste adjustment time, and dress mould, the die change also utmost point are not easy, and when unpunctual to mould, angle influence to diaphragm spring is bigger, so operator's experience and feel are had relatively high expectations.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, and providing a kind of diaphragm to suppress mould, this mould can reduce the time of mould to mould, shortens the non-cutting time of adjusting mould, it is concentric with diaphragm to guarantee that diaphragm is suppressed the tooth top size, the error that exists when avoiding manually adjusting mould.
The utility model diaphragm is suppressed mould, comprises die shank, upper die and lower die and following, unlike the prior art be: central authorities are provided with the core rod axle between patrix and counterdie.Dress is during mould, patrix with counterdie by it accurately being centered in to the core rod axle.
Owing in the utility model mould, increased to the core rod axle, make and suppress back product angle difference and suppress preceding product angle difference basically identical, differ 6-8 ' with part diaphragm angle, improved the consistence of product angle, improve diaphragm and suppressed the quality of manufacturing procedure, very big effect has been played in the raising of diaphragm heat treatment process quality, improved the consistence of diaphragm pressure, peak dot, valley point and pressing point each point pressure difference value have all played positive effect less than 250N to the first-time qualification rate that improves the assembly assembling, the brill rate of tearing open that reduces product.
Description of drawings
Fig. 1 suppresses the structural representation of mould for the utility model diaphragm.
Among the figure: 1. 7. times seats of 4. pairs of core rod axles of die shank 2. screws, 3. patrixes, 5. counterdies, 6. straight pins.
Embodiment
The utility model diaphragm suppress mould by die shank 1, patrix 3, counterdie 5, to core rod axle 4, form for following 7, die shank 1 is fixedlyed connected with patrix 3 by screw 2, core rod axle 4 is connected the central authorities of patrix 3 and counterdie 5, counterdie 5 is fixedlyed connected with following 7 by straight pin 6, dress is during mould, patrix 3 with counterdie 5 by it accurately being centered in to core rod axle 4.
Claims (1)
1. a diaphragm is suppressed mould, comprises die shank, upper die and lower die and following, and it is characterized in that: central authorities are provided with the core rod axle between patrix and counterdie.
