Abstract
The invention discloses a machining process for polishing a plug of a refrigerator door handle. The machining process comprises the following steps of: pretreatment, size selection, plug cutting, plug inserting, rough polishing, finishing polishing, tapping of an air cylinder and grinding a lathe. The method provided by the invention has the advantages that the plug is directly assembled on a handle opening for polishing without operating in steps, so that the operation flow is saved; the production efficiency is improved; the electric welding is prevented from being used; the appearance is attractive; the production quality of the handle is improved; the production efficiency is improved; the rejection rate of the handle is reduced; and the production cost is decreased. Therefore, the method provided by the invention is good for volume production.
Description
Technical field
The present invention relates to a kind of polishing 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 polishing plug additional, is technological difficulties always, and comparatively widely used usually method is: at first the plug surface is polished; Then plug is filled in the handle port, use electric torch to weld, and there is following defective in this method: at first enclosing in plug and the port; Will carry out polishing operation in advance to plug, assemble, this will make can't accomplish that zero slit installs additional between plug and the handle of polishing; And, can have a plurality of solder joints, weldering spot and weld seam by the handle port through soldering, 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 polishing plug processing technology of door handle of refrigerator, and is easy and simple to handle, appearance looks elegant, and scrappage reduces.
The present invention realizes through following technical scheme.
A kind of polishing 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 ~ 0.6 of a plug thickness;
(3) plug being filled in the handle port along sawing face fills in until can't continuing;
(4) the numb buff polishing of use is taken turns and is controlled at 2000 ~ 2200 commentaries on classics/min, and rough polishing is carried out in the plug upper surface;
(5) the use buffing is taken turns and is controlled at 2200 ~ 2400 commentaries on classics/min, and finishing polish is carried out in the plug upper surface;
(6) use air pressure to strike the pressure plug at the cylinder of 0.4 ~ 0.5mPA, fair to the garden periphery and the handle port of plug upper surface;
(7) use saw-cutting machine tool from structural that the place that agrees with of handle port and garden, plug upper surface periphery is ground.
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 0.4 of plug thickness.
Further, the above-mentioned angle that cuts face and plug sidewall is 15 ~ 30 °.
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) need not the substep operation, directly be assembled to the laggard row polishing of handle port, saved operating process, improved production efficiency at plug;
(2) avoid the use of electric welding, effectively reduce the dependence of staff's technical capability;
(3) use the handle of method processing and manufacturing of the present invention not have artificial vestige, it is comparatively attractive in appearance to polish the plug outward appearance simultaneously;
(4) the present invention is easy and simple to handle, has improved the quality of production of handle, has improved production efficiency;
(5) 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 polishing 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.
Then, its step 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 rotating speed of the sawing wheel of saw-cutting machine tool from structural is controlled at 2200 ~ 2600 commentaries on classics/min; 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 ~ 0.6 of a plug thickness, and the free height that cuts face is preferably 0.4 of plug thickness, and the angle that cuts face and plug sidewall is 15 ~ 30 °;
(4) plug being filled in the handle port along sawing face fills in until can't continuing;
(5) the numb buff polishing of use is taken turns and is controlled at 2000 ~ 2200 commentaries on classics/min, and rough polishing is carried out in the plug upper surface;
(6) the use buffing is taken turns and is controlled at 2200 ~ 2400 commentaries on classics/min, and finishing polish is carried out in the plug upper surface;
(7) use air pressure to strike the pressure plug at the cylinder of 0.4 ~ 0.5mPA, fair to the garden periphery and the handle port of plug upper surface;
