Abstract
The invention discloses a processing technology for a seamless plug of a handle of a refrigerator door, wherein the processing technology comprises the steps of pre-processing, choosing a size, cutting the plug, plugging the plug, knocking and pressing the plug by a cylinder, and finishing and cutting the processed plug by a machine tool. The processing technology has the advantages that the use of electric welding is avoided, the independence on technical skills of workers is effectively reduced, the operation is simple, the production quality of the handle is improved, the rejection rate of the handle is reduced, and the processing technology is beneficial for the mass production.
Description
Technical field
The present invention relates to a kind of seamless plug processing technology of door handle of refrigerator, be mainly used in the production and processing field of refrigerator parts.
Background technology
At present, in refrigerator parts production and processing industry, especially in the production and processing industry of door handle of refrigerator; The handle port installs the link of plug additional, is technological difficulties always, and comparatively widely used usually method is: plug is filled in the handle port; Use electric torch to weld enclosing in plug and the port, and there is following defective in this method: at first, the handle port is because the relation of welding; Have a plurality of solder joints, weldering spot and weld seam, outward appearance is not good; Secondly, have relatively high expectations for staff's technical ability proficiency, the bore of butt welding simultaneously tolerance is high, and assembly difficulty is big, and scrappage is high.
Summary of the invention
The technical problem that the present invention will solve provides a kind of seamless plug processing technology of door handle of refrigerator, and easy and simple to handle, cost is low, helps mass production.
The present invention realizes through following technical scheme.
A kind of seamless plug processing technology of door handle of refrigerator, its step is following:
(1) choosing diameter is the plug that encloses diameter 1.02 ~ 1.10 in the handle port;
(2) use saw with the even sawing of plug lower end edge circumferential edge, the bottom surface diameter that makes plug is less than enclosing diameter in the handle port, and the free height that cuts face is 0.2 ~ 0.5 of a plug thickness;
(3) plug is filled in the handle port along sawing face;
(4) use air pressure to strike the pressure plug, maintain an equal level to plug upper surface and handle port at the cylinder of 0.4 ~ 0.5mPA;
(5) use saw-cutting machine tool from structural with the smooth 0.3 ~ 1.0mm that cuts of handle port.
Further, above-mentioned plug diameter preferably is chosen for and encloses diameter 1.05 in the handle port.
Further, the above-mentioned free height that cuts face is preferably 0.3 of plug thickness.
Further, the above-mentioned angle that cuts face and plug sidewall is 10 ~ 20 °.
Further, the preferred smooth 0.5mm that cuts of above-mentioned handle port.
Further, the rotating speed of the sawing of above-mentioned saw-cutting machine tool from structural wheel is controlled at 2200 ~ 2600 commentaries on classics/min.
Further, above-mentioned technology also comprises pretreatment steps, uses saw-cutting machine tool from structural with handle port flat cut 0.1 ~ 0.5mm.
Further, the preferred flat cut 0.3mm of above-mentioned handle port.
Further, handle and plug that above-mentioned technology is chosen are Al-alloy products, and the hardness of handle material is greater than the hardness of plug material.
Beneficial effect of the present invention is:
(1) avoids the use of electric welding, effectively reduce the dependence of staff's technical capability;
(2) use the handle of method processing and manufacturing of the present invention not have artificial vestige, outward appearance is preferable;
(3) the present invention is easy and simple to handle, has improved the quality of production of handle, has improved production efficiency;
(4) effectively reduce the scrappage of handle, reduced production cost, help mass production.
The specific embodiment
According to embodiment the present invention is done further explain below.
The seamless plug processing technology of door handle of refrigerator, at first, handle and the plug chosen are Al-alloy products, guarantee the hardness of the hardness of handle material greater than the plug material.
Secondly, procedure of processing is following:
(1) preliminary treatment uses saw-cutting machine tool from structural with handle port flat cut 0.1 ~ 0.5mm, the preferred flat cut 0.3mm of handle port;
(2) choosing diameter is the plug that encloses diameter 1.02 ~ 1.10 in the handle port, and the plug diameter preferably is chosen for and encloses diameter 1.05 in the handle port;
(3) use saw with the even sawing of plug lower end edge circumferential edge; The bottom surface diameter that makes plug is less than enclosing diameter in the handle port; The free height that cuts face is 0.2 ~ 0.5 of a plug thickness, and the free height that cuts face is preferably 0.3 of plug thickness, and the angle that cuts face and plug sidewall is 10 ~ 20 °;
(4) plug is filled in the handle port along sawing face;
(5) use air pressure to strike the pressure plug, maintain an equal level to plug upper surface and handle port at the cylinder of 0.4 ~ 0.5mPA;
(6) use saw-cutting machine tool from structural with the smooth 0.3 ~ 1.0mm that cuts of handle port, the preferred smooth 0.5mm that cuts of handle port, the rotating speed of the sawing wheel of saw-cutting machine tool from structural is controlled at 2200 ~ 2600 commentaries on classics/min.
The present invention, the seamless plug processing technology of door handle of refrigerator avoids the use of electric welding, effectively reduces the dependence of staff's technical capability; Use the handle of method processing and manufacturing of the present invention not have artificial vestige, outward appearance is preferable; Easy and simple to handle, improved the quality of production of handle, improved production efficiency; Effectively reduce the scrappage of handle, reduced production cost, help mass production.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage that is familiar with this art can understand content of the present invention and also implements, and can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
