The invention has the advantages of good forming effect and surface physical property.
Description
Technical field
The present invention relates to refrigerator/refrigerator technical field, particularly the processing method of a kind of side plate of refrigerator/refrigerator, back plate and back base plate.
Background technology
At present, used side plate, back plate, the back base plate major part of refrigerator/refrigerator is sheet metal, this metallic plate comprises metal spraying plate, galvanized sheet, aluminium plating zinc plate etc., and also having a fraction of back plate, back base plate in addition is cardboard or hollow sheeting, also claims calcium-plastic board or corrugated board.Wherein, the intensity height of sheet metal, easy-formation, but price is high and corrosion easily; Though cardboard and hollow sheeting are inexpensive, be difficult to typing, and intensity is low, the appearance property of goods is relatively poor.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of processing method of side plate, back plate and back base plate of refrigerator/refrigerator is provided, this method can make sheet material better keep processability preferably, can reduce the manufacturing cost of sheet material again.
The technical scheme that the present invention solves the problems of the technologies described above is: the processing method of a kind of side plate of refrigerator/refrigerator, back plate and back base plate, select the strong plastic cement pellet of toughness for use, for example select PP, HDPE, ABS, HIPS, PVC material etc. for use, its concrete manufacturing step is as follows:
(1) selected plastic cement pellet is squeezed into plastic plate, sheet material;
(2) above-mentioned plastic sheet, sheet material are carried out cutting;
(3) sheet material after the cutting, sheet material are carried out the secondary operations moulding; Specifically, described secondary operations moulding is meant: cutting die punching press and bending forming, its operating process is: at first the sheet material after the cutting, sheet material are carried out powerful mold pressing processing with cutting die, on sheet material, form hole or groove, secondly along the groove position sheet material is carried out the bending of various angles, and keep certain shape, bending for protruding back of the body type refrigerator backplate and sheet edge is particularly important, utilize the thickness uniformity of the plate plane part after this method machine-shaping, cost is not high and save the energy;
(4) plastic sheet, sheet material after the above-mentioned secondary operations moulding being carried out surface physics handles, specifically, the surface physics processing method is the sided corona treatment method, and the sheet material of this processing of process can keep the surface polarity of long duration, can keep usually about 3 months.
As above-mentioned further improvement, above-mentioned steps can also be provided with the plate surface color treatments in (1), specifically, this plate surface color processing method is for adding look mother or toner in the process that is extruded into sheet material, sheet material, and adopt individual layer to extrude or multi-layer co-extruded technology, color is overlayed on the top layer of sheet material, sheet material.
Above-mentioned look mother's concrete content is: 4% look mother and 96% PP base-material.
The concrete content of above-mentioned toner is: 2% toner and 98% PP base-material.
Compared with prior art, the invention has the beneficial effects as follows: the method that the present invention uses can make side plate, back plate and the back base plate of refrigerator keep molding effect and surface physical properties preferably, can reduce the manufacturing cost of sheet material again.

The specific embodiment
Present embodiment is that the processing method with the back plate of refrigerator is an example.
A kind of back plate processing method of refrigerator/refrigerator adopts the strong plastic material of toughness, as PP, HDPE, ABS, HIPS, PVC etc., and adopts special plate surface to handle and forming method, and the brand-new profile material of refrigerator/refrigerator requirement is satisfied in preparation.
The simple processing route of the side plate of this refrigerator/refrigerator, back plate and back base plate is: sheet material, sheet material and surface treatment → cutting → secondary operations moulding (comprising cutting die punching press and bending forming) → sided corona treatment is carried out on the surface for plastic granule → be extruded into.
Select the plastic cement pellet of obdurability for use, for example plastic granules such as PP, HDPE, ABS, HIPS, PVC are processed above-mentioned plastic granule, and its concrete steps are as follows:
(1) plastic granule is squeezed into sheet material, sheet material and surface treatment, but usually for side plate, for the side plate that makes plastic shaping has metal appearance, can also be in being extruded into sheet material, sheet material and surface-treated process, add a certain amount of look mother or toner and adopt multi-layer co-extruded technology, color is overlayed on the top layer of side plate, so just reduced spraying process, described look mother's content is: 4% look female and 96% PP base-material, the concrete content of toner: contain 2% toner and 98% PP base-material.
(2) plastic sheet, sheet material are carried out cutting, Fig. 1 is the structural representation of the refrigerator backplate 1 after the cutting;
(3) sheet material after the cutting, sheet material are carried out the secondary operations moulding, comprise cutting die punching press and bending forming, detailed process is: at first, carry out powerful mold pressing processing with cutting die, on sheet material, form hole or groove, secondly sheet material is carried out the bending of various angles along the groove position, and keep certain shape, bending for protruding back of the body type refrigerator backplate and sheet edge is particularly important, utilizes the thickness uniformity of the plate plane part after this method machine-shaping, and cost is not high and save the energy.Fig. 2 is with the back plate structure schematic diagram after the cutting die punching press, and wherein 2 are punching, and 3 is the cutting die impression, and 4 is bending edges; Fig. 3 is an A place enlarged drawing among Fig. 2, and Fig. 4 is the refrigerator backplate structural representation after the bending; Fig. 5 is the back plate side view after the bending;
(4) plastic sheet, sheet material being carried out surface physics handles, particularly surperficial strong " activation " handled for the nonpolar and low polar material (as PP, HDPE, HIPS etc.) of surperficial 'inertia', make plate surface have enough adhesions, make the PU foam can directly stick on sheet material the PU foam that is used to be incubated; Simultaneously also make plate surface that printing ink is had enough adhesions, thereby be convenient to surface printing pattern, literal etc.Surface treatment method is meant mainly and carries out sided corona treatment when sheet material has just been extruded at once that the sheet material of this processing of process can keep the surface polarity (about 3 months) of long duration; If using plasma is handled, or to carrying out surface treatment before and after the plate forming separately, then the timeliness of its intensity, maintenance polarity is not as good as the former.
The present invention is applicable to the side plate/back plate/fabircated shapes such as back base plate that directly combine with the PU foam in refrigerator/refrigerator, does not comprise the thermoforming of plastic plate.When the back plate that is made into refrigerator/refrigerator with the sheet material or the sheet material of this kind method moulding, side plate, back base plate, because its PU foam that can and have insulation effect directly bonds, intensity is enhanced, therefore the requirement to sheet material, the intensity of sheet material own can suitably reduce, the thickness of sheet material, sheet material is attenuate suitably, thickness range is about 0.5-2.0mm, so just can make side plate, back plate and back base plate with thin sheet material, thereby the weight of refrigerator/refrigerator is also descended.
