Description

A Welding Fixture for Electronic Ceramic Steel Needle and Tungsten Alloy Combination Mold

technical field

The utility model relates to the technical field of electronic ceramic production equipment, in particular to a welding fixture for an electronic ceramic steel needle and a tungsten alloy combined mold.

Background technique

Ceramics that can use electricity and magnetic properties in the electronics industry are called electronic ceramics. Electronic ceramics are ceramics with new functions obtained through the control of surface, grain boundary and size structure. It can be widely used in energy, household appliances, automobiles, etc.

In the production process of fine ceramic products, especially when dry pressing is used to produce ceramic products, as the pressing density increases during the pressing process, the wear of the ceramic powder on the molding die will increase sharply, which will eventually lead to changes in the size of the product. In order to solve the above wear problem, due to the high hardness and good wear resistance of tungsten alloy, tungsten alloy is usually used in the manufacture of fine ceramic molds, but the cost of tungsten alloy molds is high, and the molding part of the mold is usually only a small part of the upper end of the mold. Therefore, the mold is usually processed and manufactured in the form of a combined mold. One part of the combined mold is an ordinary steel needle, and the other part is a tungsten alloy. The combination of the two needs to be welded to form a whole. During the welding process, usually the tungsten alloy needs to be processed into special-shaped parts, and the steel needle can be a round rod, which puts forward higher requirements for the welding fixture.

Therefore, it is the key to solve this technical problem to ensure the concentricity and verticality of the two components of the steel needle and the tungsten alloy, and to design a reasonable and operable welding fixture.

Utility model content

In order to solve the problems in the prior art, an embodiment of the utility model provides a welding fixture for a combination mold of an electronic ceramic steel needle and a tungsten alloy. Described technical scheme is as follows:

Provided is a welding fixture for an electronic ceramic steel needle and tungsten alloy combined mold, the welding fixture includes: a fixture base, a steel needle pressure plate and a tungsten alloy pressure plate, the steel needle pressure plate and the tungsten alloy pressure plate are respectively passed through four elastic The bolts are installed in a suitable manner with the fixture base; the fixture base is longitudinally provided with a plurality of steel needle tungsten alloy inserting grooves, and the dimensions of the multiple steel needle tungsten alloy inserting grooves are the same or step by step Incremental; the middle part of the fixture base is provided with a welding operation window penetrating up and down.

Further, after the steel needle press plate and the tungsten alloy press plate are assembled with the fixture base, the steel needle press plate and the tungsten alloy press plate have the same width as the welding operation window in the longitudinal direction.

The beneficial effects brought by the technical solution provided by the embodiment of the utility model are:

By setting the steel needle pressure plate and the tungsten alloy pressure plate to cooperate with the fixture base, and the steel needle and the tungsten alloy are inserted in the same longitudinal groove, so that the verticality and concentricity of the steel needle and the tungsten alloy can be ensured during welding. Consistent, improve the welding efficiency and improve the overall quality of the mold after welding.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings that need to be used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some implementations of the present invention. For example, those of ordinary skill in the art can also obtain other drawings based on these drawings on the premise of not paying creative efforts.

Fig. 1 is a schematic perspective view of the three-dimensional structure of the welding fixture provided by the embodiment of the present invention.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the implementation of the present utility model will be further described in detail below in conjunction with the accompanying drawings.

Example

This embodiment provides a welding fixture for an electronic ceramic steel needle and tungsten alloy combined mould, please refer to Fig. The alloy pressing plate 3 is fitted to the fixture base 1 through four elastic bolts 4 respectively. A plurality of steel pin tungsten alloy fitting grooves 11 are longitudinally provided on the fixture base 1 , and the dimensions of the multiple steel needle tungsten alloy fitting grooves 11 are the same or increase step by step. A welding operation window 12 penetrating up and down is opened in the middle of the fixture base 1 . In this way, during welding, as long as the steel needle and the tungsten alloy are correspondingly placed in the steel needle tungsten alloy engagement groove 11 and connected well, the welding can be conveniently performed. The size of the plurality of steel needle tungsten alloy clamping grooves 11 increases step by step, so that one fixture is suitable for various types of mold welding, which improves the versatility of the fixture.

After the steel needle pressing plate 2 and the tungsten alloy pressing plate 3 are assembled with the fixture base 1, the steel needle pressing plate 2 and the tungsten alloy pressing plate 3 have the same width as the welding operation window 12 in the longitudinal direction. In this way, the welding operation space is larger, the welding efficiency is improved and the operation is convenient.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models. the
