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, handle port installs the link of polishing plug additional, technological difficulties always, conventionally comparatively widely used method is: first polishing is carried out in plug surface, then plug is filled in to handle port, use electric torch to enclosing and weld in plug and port, and there is following defect in this method: first, to plug, to carry out polishing operation in advance, assemble again, this will make cannot accomplish that zero gap installs additional between the plug of polishing and handle, and by soldering, can there are a plurality of solder joints by handle port, weldering spot and weld seam, outward appearance is not good, secondly, for staff's technical ability proficiency, have relatively high expectations, Welded Pipe id tolerance requirement is simultaneously high, and assembly difficulty is large, and scrappage is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of polishing plug processing technology of door handle of refrigerator, easy and simple to handle, appearance looks elegant, and scrappage reduces.
The present invention is achieved through the following technical solutions.
A polishing plug processing technology, its step is as follows:
(1) choosing diameter is in handle port, to enclose the plug of diameter 1.02 ~ 1.10;
(2) use saw by the even sawing of plug lower end edge circumferential edge, the bottom surface diameter of plug is less than in handle port and encloses diameter, the free height that cuts face is 0.2 ~ 0.6 of plug thickness;
(3) plug is filled in to handle port until cannot continue to fill in along sawing face;
(4) use numb buff polishing to take turns and be controlled at 2000 ~ 2200 turn/min, rough polishing is carried out in plug upper surface;
(5) use buffing to take turns and be controlled at 2200 ~ 2400 turn/min, finishing polish is carried out in plug upper surface;
(6) use air pressure to strike pressure plug at the cylinder of 0.4 ~ 0.5mPA, fair to 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 is preferably chosen for and in handle port, encloses diameter 1.05.
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 turn/min.
Further, above-mentioned technique also comprises pretreatment steps, uses saw-cutting machine tool from structural by 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 technique 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) without substep operation, directly at plug, be assembled to the laggard row polishing of handle port, saved operating process, improved production efficiency;
(2) avoid using electric welding, effectively reduce the dependence of staff's technical capability;
(3) use the handle prosthetic vestige of method processing and manufacturing of the present invention, the plug of polishing simultaneously outward appearance is comparatively attractive in appearance;
(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, be conducive to mass production.
the specific embodiment
According to embodiment, the present invention is described in further detail below.
The polishing plug processing technology of door handle of refrigerator, first, handle and the plug chosen are Al-alloy products, guarantee that the hardness of handle material is greater than the hardness of plug material.
Then, its step is as follows:
(1) pretreatment, is used saw-cutting machine tool from structural by handle port flat cut 0.1 ~ 0.5mm, the preferred flat cut 0.3mm of handle port;
(2) choosing diameter is in handle port, to enclose the plug of diameter 1.02 ~ 1.10, and plug diameter is preferably chosen for and in handle port, encloses diameter 1.05;
(3) use saw by 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 turn/min, the bottom surface diameter of plug is less than in handle port and encloses diameter, the free height that cuts face is 0.2 ~ 0.6 of plug thickness, 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 is filled in to handle port until cannot continue to fill in along sawing face;
(5) use numb buff polishing to take turns and be controlled at 2000 ~ 2200 turn/min, rough polishing is carried out in plug upper surface;
(6) use buffing to take turns and be controlled at 2200 ~ 2400 turn/min, finishing polish is carried out in plug upper surface;
