From the later stage eighties in last century, the domestic research that begins to carry out punching press welding impeller is developed CYB series stamping-welded centrifugal pump by Shanghai University of Science and Technology at first, and produces in batches in river, Guangdong new stainless steel punching press pump Industrial Co., Ltd.At present, ground such as Guangdong, Jiangsu, Zhejiang, Anhui, Shandong have how tame water pump manufacturer to carry out the research and the production of stainless steel pump, and have obtained a series of achievement.
With abroad compare, the research of domestic punching press welding pump is started late, comprise aspects such as waterpower design and manufacturing process, all need on existing basis, strengthen research, and be subjected to the restriction of technological level, the manufacture view of manufacturing process aspect, the especially impeller of domestic punching press welding pump also has many problems etc. to be solved.As: back shroud of impeller and blade adopt resistance welded, and the two can not be coupled postwelding well, produce crossfire between runner; The solder joint place easily comes off, and impeller is destroyed; Distortion etc. appears in the forward and backward cover plate of welding back impeller.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned defective workmanship, solves in the stainless steel punching press welding pump production process, and the splashing of existence impacted greatlyyer to electrical network, and face of weld weldering trace is crossed problem such as dark and the special-purpose stored energy welding of a kind of stainless steel water pump blade that designs is met sb. at the airport.
The technical solution of the utility model: the special-purpose stored energy welding of stainless steel water pump blade of the present utility model is met sb. at the airport and is comprised control power supply, large power energy storage discharge transformer, electrode, the cylinder block of left and right sides welding machine frame and middle upper part connects into gantry form, and there is the bottom electrode bearing corresponding cylinder block below; A large power energy storage discharge transformer is installed separately, two large power energy storage discharge transformers connected in parallel in the welding machine frame of the left and right sides; Weld cylinder is installed on cylinder block, and cylinder axis is connected with the pressurization main shaft; The pressurization main shaft is connected slide plate and connects with top electrode, four jiaos of top electrode connection slide plate are passed 4 vertically-guided bars respectively; Article 4, the vertically-guided bar is separately fixed at up and down on cylinder block and the lower electrode holder; The bottom that top electrode connects slide plate is equipped with the brass electrode seat; Top electrode is positioned at brass electrode seat below; Brass electrode seat down is installed on the bottom electrode bearing, bottom electrode is installed on the following brass electrode seat, the secondary coil of two large power energy storage discharge transformers is attempted by respectively on brass electrode seat and the following brass electrode seat.
Advantage of the present utility model: 1. bonding power is big, the weld strength height; Welding quality is good, and nothing is splashed; The production efficiency height; Labour intensity is low; Fault rate is low, is convenient to care and maintenance.
Specifically:
● adopt the welding manner of capacitance energy storage type to solve the problem of stainless steel water pump blade (adopt other modes weld existence) surface discolouration, improved the product appearance quality;
● adopt high-power dual transformer as the source of welding current, sufficient welding energy has been arranged, guaranteed the weld strength of product, reached the product strength quality requirement;
● adopt four guide posts to make guide-localization, guaranteed the depth of parallelism of upper and lower electrode operation, the pressure unanimity that workpiece each salient point in pressure process is subjected to, thus reached the welding current equilibrium of each salient point;
