Abstract
The utility model relates to a tooling die for a movable contact of a vacuum circuit breaker, which consists of the tooling die of the contact (1), a bracket of the tooling die of the movable contact (2) and a pressing machine (3), wherein the bracket of the tooling die of the movable contact (2) is fixed on a bottom plate of the pressing machine (3), the tooling die of the contact (1) is fixed on the bracket of the tooling die of the movable contact (2), the tooling die of the contact (1) aims at the bracket of the tooling die of the movable contact (2), and pressure is exerted by the pressing machine (3); the tooling die of the contact (1) is shaped like a circular platform, the diameter of the front end is small while that of the back end is big, a spring of the movable contact is stretched under the pressure of the pressing machine, the caliber of the movable contact (4) is expanded by the tooling die of the contact (1), the movable contact can be smoothly mounted on a contact arm (5) in this way, and then the tooling die of the contact (1) can be removed. The tooling die of the movable contact of the vacuum circuit breaker can simplify the process of mounting the movable contact, save time, improve efficiency and reduce damage to the movable contact caused by beating during the traditional mounting process.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker installation and debugging instrument, relates in particular to that large current interruption device moving contact also is the sectional fixture of Mume flower contact in the vacuum circuit-breaker.
Background technology
Large current interruption device moving contact is also referred to as Mume flower contact, is a vitals in the vacuum circuit-breaker.Moving contact is hollow cylindrical, at the inwall of cylindric moving contact a groove is set, and the diameter of groove is bigger than the two ends diameter of moving contact.The diameter of the contact arm front end of vacuum circuit-breaker is consistent with the diameter of groove, length is consistent with the degree of depth of groove, contact arm is except that with its diameter of part of groove interlock and groove are consistent, the diameter of other parts is consistent with the diameter at moving contact two ends, so just can make the tight interlock of contact arm and moving contact.Fix with spring around the moving contact cylinder, because can stretch during spring stress, so the bore of moving contact can extend.The point diameter of contact arm is bigger than the two ends diameter of moving contact, therefore, make a end that the bigger contact arm of diameter makes its groove that enters into moving contact that spring is stretched to make moving contact by less contact one end of diameter to diameter greater than contact arm, could success contact is installed on the contact arm.The spring that intensity is very big around the moving contact is stretched, thus a technical barrier that moving contact is installed on the contact arm smoothly be exactly the installation of moving contact to face.Traditional method is to beat on moving contact with hammer, thereby spring is stretched, and by this way moving contact is installed.The defective of traditional method is a time and effort consuming, and efficient is low.Simultaneously, in the process of beaing, damage moving contact easily, make the moving contact distortion easily, thereby influence the performance of whole vacuum circuit-breaker.
The utility model content
At the above-mentioned defective that exists in traditional moving contact installation process, the utility model provides a kind of moving contact simple moving contact moulds of industrial equipment easier for installation that can allow.
For achieving the above object, the technical scheme of taking of the present utility model is: a kind of vacuum circuit-breaker moving contact moulds of industrial equipment, form by contact moulds of industrial equipment (1), moving contact frock die shoe frame (2) and forcing press (3), it is characterized in that: moving contact frock die shoe frame (2) is fixed on the base plate of forcing press (3), and contact moulds of industrial equipment (1) are fixed on the moving contact frock die shoe frame (2); Contact moulds of industrial equipment (1) are aimed at moving contact frock die shoe frame (2), exert pressure by forcing press (3); Contact moulds of industrial equipment (1) are round table-like, the little rear end of point diameter diameter is big, spring at the following moving contact of pressure of forcing press stretches, by contact moulds of industrial equipment (1) moving contact (4) bore is swollen, can successfully be installed in moving contact on the contact arm (5) like this, take out contact moulds of industrial equipment (1) again and get final product.
Beneficial functional of the present utility model is: make installation moving contact process simple, save time, raise the efficiency.Reduce the conventional mounting process and beaten the infringement that causes to moving contact, improved the stability of vacuum circuit-breaker overall performance, improved the qualification rate of product.
Description of drawings
Fig. 1 is the fundamental diagram of vacuum circuit-breaker moving contact moulds of industrial equipment;
Fig. 2 is contact moulds of industrial equipment cutaway views.
Marginal data:
Contact moulds of industrial equipment (1), moving contact frock die shoe frame (2), forcing press (3), moving contact (4), contact arm (5).
Embodiment
Now the utility model is described in further detail in conjunction with the accompanying drawings.
The first step: moving contact frock die shoe frame (2) is fixed on the base plate of forcing press (3); Contact moulds of industrial equipment (1) lower end is embedded on the moving contact arm, and the upper end then contacts with contact arm (5) and is connected, and contact moulds of industrial equipment (1) are fixed on the moving contact frock die shoe frame (2);
Second step: contact moulds of industrial equipment (1) are aimed at moving contact frock die shoe frame (2), and forcing press (3) lower platen is exerted pressure downwards to contact arm (5);
The 3rd step: under the effect of press pressure, moving contact (4) just is installed on the contact arm, takes out contact moulds of industrial equipment (1) again and gets final product.
Claims (2)
1. vacuum circuit-breaker moving contact moulds of industrial equipment, form by contact moulds of industrial equipment (1), moving contact frock die shoe frame (2) and forcing press (3), it is characterized in that: moving contact frock die shoe frame (2) is fixed on the base plate of forcing press (3), contact moulds of industrial equipment (1) are fixed on the moving contact frock die shoe frame (2), and contact moulds of industrial equipment (1) are aimed at moving contact frock die shoe frame (2).
2. moving contact moulds of industrial equipment according to claim 1, it is characterized in that: contact moulds of industrial equipment (1) are round table-like, the little rear end of point diameter diameter is big, spring at the following moving contact of the pressure of forcing press (4) stretches, by contact moulds of industrial equipment (1) moving contact (4) bore is swollen, can successfully be installed in moving contact on the contact arm (5).
