Abstract
The invention discloses a surfacing device for sealing elements, and relates to the technical field of manufacturing of hard-alloy surfacing equipment. The surfacing device comprises a vacuum pump which is connected with one end of a vacuum pipeline. The other end of the vacuum pipeline is connected with one end of a filter. The other end of the filter is connected with one end of a first pipeline. The other end of the first pipeline is connected with one end of a first vacuum butterfly valve. The other end of the first vacuum butterfly valve is connected with one end of a second pipeline. The other end of the second pipeline is connected with a vacuum chamber. A sensor is arranged in the vacuum chamber. Through the surfacing device, the problems that an existing surfacing method is low in efficiency, high in labor intensity and high in cost can be solved.
Description
Technical field
The present invention relates to hard alloy overlay welding equipment manufacturing technology field, especially a kind of seal build-up welding apparatus of vacuum induction.
Background technology
The seal of metal uses flame, plasma or non-melt argon arc weld deposit CoCrW carbide alloy, to improve the performance such as against corrosion and wear-resisting of seal, has become a kind of means improving seal durability.But adopt these overlaying methods, not only efficiency is low, and labour intensity is large, and easily produces the defect of oxidation, pore or slag inclusion, can not ensure the quality of product.In these methods, plasma spray effect is better, but its material used is more, and cost is higher.
Summary of the invention
The object of this invention is to provide a kind of seal build-up welding apparatus, it is low that it can solve existing overlaying method efficiency, the problem that labour intensity is large and cost is high.
In order to solve the problem, the technical solution used in the present invention is: this seal build-up welding apparatus, include vavuum pump, described vavuum pump is connected with one end of vacuum pipe, the other end of described vacuum pipe is connected with one end of filter, the other end of described filter is connected with first pipeline one end, the other end of described first pipeline is connected with one end of the first vacuum dish valves, the other end of described first vacuum dish valves is connected with second pipe one end, and the other end of described second pipe is connected with vacuum chamber; Inductor is provided with in described vacuum chamber.
In technique scheme, more specifically scheme can also be: described inductor is tunnel type inductor.
Further: be provided with on described first pipeline and regulate, regulate described in and be connected with vacuum meter; Described second pipe is provided with the second vacuum dish valves.
Further: on described vacuum pipe, to be provided with bellows.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention:
1, will improve the built-up welding efficiency of seal and ensure surfacing quality, must carry out in a vacuum, the present invention is provided with vavuum pump and vacuum chamber, is provided with inductor in a vacuum chamber, so ensure that surfacing quality; Inductor of the present invention adopts tunnel type inductor, seal can be made to heat gradually in tunnel, until shaping.Along with the raising of heating-up temperature, vacuum is also along with rising, and it not only increases efficiency like this, and seal Forming Quality have also been obtained guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Seal build-up welding apparatus shown in Fig. 1, include vavuum pump 1, vavuum pump 1 is connected with one end of vacuum pipe 3, the other end of vacuum pipe 3 is connected with one end of filter 4, the other end of filter 4 is connected with first pipeline 5 one end, the other end of the first pipeline 5 is connected with one end of the first vacuum dish valves 6, and the other end of the first vacuum dish valves 6 is connected with second pipe 7 one end, and the other end of second pipe 7 is connected with vacuum chamber 11; Inductor 10 is provided with in vacuum chamber 11.Inductor 10 is tunnel type inductor.
First pipeline 5 is provided with and regulates 8, regulate 8 and be connected with vacuum meter 9; Second pipe 7 is provided with the second vacuum dish valves 13.Vacuum pipe 3 is provided with bellows 2.
Seal 12 is arranged in vacuum chamber 11, and in the present embodiment, the diameter of seal 12 is φ 5 ~ φ 50 millimeters.
Vacuum induction pile-up welding is under vacuum, melts the packing material (alloy powder) in workpiece, make it molten with workpiece substrate and be integrated with high-frequency induction.
