Abstract
The present invention provides a kind of stainless steel end faces to dock seamless-molding technique, and by blowing, after punching machine blanking bending forming, two end edges for preparing it connection carry out compression trimming, makes two smooth impulse- free robustness of end edge；Two end edges are welded from melting apparatus then at high temperature, workpiece is made to connect into an entirety；One-piece machine member is put into roll-in rolling equipment to prolong it from molten junction progress roll-in；After the completion, it is squeezed twice in extrusion die；Last time punching molding.The present invention to end edge welding using high temperature from molten technology, do not add additional materials and directly fuse together two end edges, the metallicity and intensity of junction are consistent with overall material, good airproof performance, highly-safe；Prolonged by roll-in and be extruded to shape, junction is made to be fused into one state, it is smooth and beautiful that cabinet overall appearance is seamless；Meanwhile operating in equipment and being equipped with controllable system, when use, can adjust operating parameter in real time according to the actual situation and meet actual needs.
Description
Technical field
The present invention relates to stainless steel moulding process, specially a kind of seamless-molding technique of stainless steel end face docking.
Background technique
Box heat exchanger is the core component of gas heater, and the quality of moulding process determines the heat exchange effect of heat exchanger
Rate and security performance.Traditional box heat exchanger longitudinally has one using metal copper material and stainless steel materials machine-shaping, cabinet
Connector is stung seam docking using buckle and is fixed.This docking mode makes box appearance out-of-flatness, and due to heat exchanger
Working characteristics, cabinet are chronically in the environment of hot and cold alternation, and the buckle longitudinally docked is stung by expanding with heat and contract with cold at seam, when
Between it is one long, the gap between stainless steel will become larger, and box body tightness is deteriorated, cause water heater using when thermal energy leak, reduction is changed
The thermal efficiency of hot device increases energy consumption；It even can then cause gas leakage when serious, influence using safe.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of seamless interfacing, and smooth in appearance is beautiful,
Interface connection perfection does not have apertured stainless steel end face docking seamless-molding technique.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of stainless steel end face docking seamless-molding technique, comprising the following steps:
(1) stainless steel material is placed on discharging frame, by automatic feeding, carries out blanking after carrying it into punching machine, fall
The stainless steel material to get off can bending and forming；
(2) workpiece obtained in step (1) is packed into automatic pressing machine, two end edges for preparing connection to the workpiece are first pressed
Next trimming；
(3) two end edges after trimming are welded from melting apparatus in high temperature, workpiece is made to link into an integrated entity；
(4) integrated workpiece is put into roll-in rolling equipment, roll-in is carried out from molten junction to it and is prolonged；
(5) workpiece obtained in step (4) is swung in into extrusion equipment, is squeezed twice in extrusion die, finally at
Type；
(6) molding workpiece is put into disposable punching in perforating press.
Preferably, in step 1, the stainless steel material after blanking is bent into rectangular parallelepiped structure.
Preferably, in step 3, high temperature is directly fused two end edges one using argon arc welding technology from melting apparatus
It rises.
Preferably, in steps of 5, the shape of extrusion die matches with one-piece machine member shape.
Preferably, it is set in automatic feeding, punching machine, automatic pressing machine, high temperature from melting apparatus, roll-in rolling equipment, extruding
Controllable system is built-in in standby and perforating press.
The beneficial effects of the present invention are: (1) workpiece passes through in automatic pressing machine compresses trimming, make two smooth nothings of end edge
Burr keeps its molding effect in subsequent seamless welding more preferable；(2) high temperature does not need addition additional materials progress from molten technology
Welding, directly fuses together the stainless steel material of two end edges, the metallicity and intensity of junction and whole stainless steel
Matter is consistent, and linking is close, good airproof performance, highly-safe；(3) prolonged by roll-in, junction is made to be fused into one state, it is seamless
It is again beautiful；(4) stainless steel materials are by being extruded to shape, the smooth beauty of cabinet overall appearance；(4) being equipped in operation equipment can
Control system, when use, can adjust operating parameter in real time according to the actual situation and meet actual needs, more scientific；(5) there is no pass
The security risk of system docking, heat exchange efficiency height, long service life.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described, it should be understood that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
The present invention relates to a kind of stainless steel end faces to dock seamless-molding technique, comprising the following steps:
(1) firstly, by etc. stainless steel material to be processed be placed on discharging frame, between discharging frame and punching machine be equipped with self-feeding
Device, by automatic feeding, stainless steel material is brought into punching machine automatically, carries out blanking, and the stainless steel material fallen can bending
All size can be bent out by controlling the dimensional parameters of punching machine blanking at cuboid；
(2) workpiece obtained in step (1) is packed into automatic pressing machine, in automatic pressing machine, machine can accurately be found
The workpiece prepares two end edges of connection, and trimming after first compressing makes two smooth impulse- free robustness of end edge, facilitates subsequent welding；
(3) two end edges after trimming are welded from melting apparatus in high temperature, high temperature uses argon arc welding from melting apparatus
Connection technology does not need to add additional material, can directly fuse together the stainless steel material of two end edges, connect workpiece
It is connected into entirety, the metallicity and intensity of junction are consistent with whole stainless steel material；
(4) one-piece machine member is put into roll-in rolling equipment, roll-in is carried out from molten junction to it and is prolonged, junction is fused into
Integrated state, it is seamless and beautiful；
