Abstract
The invention discloses a manufacture technique for a refrigerant evaporator siphon for an icebox refrigerant device which solves the problems like low finished product rate and high fault rate of the siphon technique for the existing internal screwed conduit used by an air conditioner used by an icebox evaporator and has the advantages of simple method, high finished product rate, continuously bent manufacture and few welding points, etc. The technique including (1) selecting an air conditioner copper tube on the cold light surface or an internal screwed copper tube reaching the standard;(2) confirming the length of the tube material needed by bending and manufacturing a workpiece according to the requirement of manufacture length and sealing one end of the copper tube by welding; (3) connecting the copper tube with an air charging or a liquid charging device under a normal temperature and charging the needed air pressure or hydraulic pressure according to a proportion of 1 : 0.12 to 0.4 thread/MPa between the thickness of the copper tube and the pressure of the inside air or liquid and then sealing the other end of the copper tube;(4) putting into a bending machine to bend and form;(5) releasing pressure and charging nitrogen in the copper tube to remove the dust; (5) packing and warehousing after finishing manufacture.
Description
Technical field
The present invention relates to a kind of manufacture craft of evaporator winding pipe, relate in particular to a kind of manufacture craft of refrigeration evaporator winding pipe of refrigerator refrigerating device.
Background technology
In recent years because copper valency soaring makes a lot of producers of refrigerator refrigerator refrigeration plant evaporimeter price growth at double with having become aluminum pipe and group's enlightening pipe, aluminum pipe and help the corrosion-resistant of enlightening pipe.Copper is just different, the strong long service life of the corrosion resistance of copper, select for use the idle call inner screw thread copper pipe when reducing cost, to increase heat-exchange capacity again, it is very big that but it bends difficulty, tradition bends process for place steel core in copper pipe, last bending machine bends, but when bending copper pipe break easily, cause yield rate low, and because bending machine is difficult too big, cause the copper pipe limited length, working (machining) efficiency is lower, can not continuous bending, time-consuming more, must weld together use by multistage, refrigerating fluid easily leaks, and fault rate is higher.
Summary of the invention
Purpose of the present invention is exactly in order to solve present idle call riffled tube when being used for evaporator of refrigerator, the yield rate of its bending technique is low, problems such as fault rate height, provide that a kind of to have method simple, the yield rate height, but continuous bending, the manufacture craft of the refrigeration evaporator winding pipe of refrigerator refrigerating device of advantage such as pad is few.
For achieving the above object, the present invention adopts following technical scheme:
A kind of manufacture craft of refrigeration evaporator winding pipe of refrigerator refrigerating device, its method be,
(1) selects air conditioner refrigerating light face copper pipe or inner screw thread copper pipe up to standard for use;
(2) according to making the length needs, determine to bend the required pipe material of workpiece length, with copper pipe one end welded seal;
(3) under the normal temperature copper pipe being connected with inflation or charging device, is 1 according to copper pipe thickness and internal gas or fluid pressure ratio: 0.12-0.4 silk/Mpa, fill required air pressure or hydraulic pressure, and then the copper pipe other end is sealed;
(4) machine of bending bends moulding on;
(5) put pressure, again copper pipe is poured the nitrogen dedusting;
(6) complete packing warehouse-in gets final product.
In the described step (3), copper pipe thickness and internal gas or fluid pressure ratio are 1: 0.2-0.3 silk/Mpa.
In the described step (5), open copper pipe one end when putting pressure and get final product.
Adopt manufacture craft of the present invention, when bending bend pipe, liquid that has pressure or gas that utilization charges into, play the supporting role of the steel core of adding in the original technology, but the problem of easily having broken when effectively having avoided copper pipe to bend, the length of body can be unrestricted simultaneously, and the efficient that bends also improves greatly, moulding is not limited by mould, is easy to processing for some shaped pieces.
The invention has the beneficial effects as follows: method is easy, and copper pipe is difficult for breaking, and processing length is unrestricted, production efficiency height, yield rate height.
The specific embodiment
The present invention will be further described below in conjunction with embodiment.
Processing technology of the present invention is:
(1) selects air conditioner refrigerating light face copper pipe or inner screw thread copper pipe up to standard for use;
(2) according to making the length needs, determine to bend the required pipe material of workpiece length, with copper pipe one end welded seal;
(3) under the normal temperature copper pipe being connected with inflation or charging device, is 1 according to copper pipe thickness and internal gas or fluid pressure ratio: 0.12-0.4 silk/Mpa, fill required air pressure or hydraulic pressure, and then the copper pipe other end is sealed;
(4) machine of bending bends moulding on;
(5) put pressure, open copper pipe one end when putting pressure and get final product, again copper pipe is poured the nitrogen dedusting;
(6) complete packing warehouse-in gets final product.
In the described step (3), copper pipe thickness and internal gas or fluid pressure ratio are 1: 0.2-0.3 silk/Mpa.
The present invention's used tool in the process of bending is known equipment, repeats no more.
