The process comprises the following steps: (1) selecting material and winding a spring; (2) tempering; (3) forming on a processing die; (4) after die forming, setting the shape of the spring; (5) coloring the spring; (6) oiling the surface of the spring after coloring; and (7) packaging the spring. The spring can be processed into a spring with two conical ends and a cylindrical middle part through die forming; the steel wire of the spring is pressed into a rectangular shape to meet the design requirement; the stable shape of spring is guaranteed through the shape setting; and finally the product is subjected to detection and acceptance.
Description
Technical field
The present invention relates to a kind of processing technology of spring, the bend pipe spring machining process of especially a kind of production PVC electrical casing pipe (clod wash pipe).
Background technology
The PVC Main Ingredients and Appearance is a polyvinyl chloride, and the superiors of skin covering of the surface are lacquers, and middle main component is a polyvinyl chloride, and orlop is a back of the body coating adhesive.It is liked deeply in the world today, rather popular and a kind of synthetic material of also being widely used.From eighties of last century beginning of the eighties, country widelys popularize and uses the pvc pipe, and has formulated a series of policy, system, standard, has also accumulated many experiences.Develop into today, possessed perfect product standard, detection method standard and detection means, construction work technical specification etc., thereby unified the specification and the quality index of product, realized the interchangeability of product.This development that pvc feedwater piping has been described has entered the maturity period, and product quality and construction quality have all had guarantee, thereby has guaranteed the result of use of pvc feedwater piping.
At present; in house decoration; because of pvc pipe can be crooked; toughness is characteristic preferably, also is used to wear electric wire, when electric wire is arranged in doors; need curve various angle; arrange that so that can adapt to the electric wire of each corner corner in the house existing P VC casing buckling adopts directly crooked, the result causes the PVC casing deformation easily or produces ripple; seriously also can cause closed and cracking; closed back electric wire is not easy to pass, and cracking can influence the protection effect again, and the local size in distortion back can become big; influence laying herein; if connect as transition, will cause expense to increase, and the adaptability of angle is not high with the plastic cement elbow.Therefore a kind ofly can be applicable to that pvc pipe is directly crooked and can guarantee that again the mould of bending effect is just very important, can save working strength of workers greatly, can also reduce decoration cost simultaneously.
Announced a CN2400198Y patent on October 11st, 2000 such as Patent Office of the People's Republic of China, name is called the bend pipe floating die assembly, comprise a columniform spring section, the two ends of spring section are equipped with one as the spring head end of receiving, swelling that protects handle, and the spring head end is outer taper of opening.
Summary of the invention
The purpose of this invention is to provide a kind of bend pipe spring machining process, be used for processing pvc pipe is carried out the bend pipe spring that manual bend pipe uses, make things convenient for the workman freely to use, and can adapt to different angle of bend and bending direction.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bend pipe spring machining process is characterized in that comprising the steps:
(1) selection is selected suitable material and by spring coiling machine it is carried out wind spring, processes the thick embryo shape of spring;
(2) behind the wind spring spring put into and carry out tempering in the tempering furnace;
(3) cooling and move on on the processing mold and be shaped behind the spring temper, the centre of spring is cylindric, and the two ends of spring are cone-shaped, and the place, both ends of spring forms hook, and the section of steel wire of spring is a rectangle;
(4) behind the die forming spring is formalized, continue pressurize during setting, the dwell time is controlled at 30-90min;
(5) spring is marked look, adopt dark;
(6) mark look rear spring surface oils;
(7) pack at last.
The bend pipe spring is used for to the pvc pipe manual bending, a bend pipe spring can be finished repeatedly pvc pipe bending, therefore require the flexural fatigue coefficient of spring to meet the demands, number of bends is wanted to reach designing requirement, to consider the fatigue strength of material in the time of selection, can form stress at spring inner in the wind spring process and concentrate, eliminate stress by tempering process, prevent that the stress existence from causing spring to rupture, and prolonged the service life of spring in the bend pipe process; On mould, be shaped, spring is processed into designing requirement, and two ends are taper, conveniently spring are inserted in the pvc pipe, the centre is cylindrical, can not deform in the bending pvc pipe, the spring steel wire cross section is a rectangle, improves the applying degree of spring surface and pvc pipe inner surface, when making the PVC bending, crackle etc. can not occur, the hook at both ends conveniently moves to spring any position of pvc pipe inside, has improved the applicability of spring; Spring is carried out dark color mark look, thereby improve the aberration contrast between pvc pipe and the spring, can locate fast after making things convenient for spring to penetrate in the pvc pipe.
As preferably, in the time of wind spring, to reserve the gap between steel wire and the steel wire, match with the size that spring steel flattens expansion in this gap.This gap is mainly used to the change in size that the spring steel wire distortion brings, and prevents to overlap between the adjacent springs wire loop, interferes spring tube bending.
As preferably, spring temper adopts average tempering, and temperature is controlled at 380-450 ℃.
As preferably, in the die forming operation spring to be fixed, the outside of spring is all coated, and the inside of spring is supported by lining, gradually spring is exerted pressure, and reaches the design size of spring gradually.The inside dimension of lining control spring, thereby the external dimensions of control spring guarantee that the external diameter of spring adheres to specification.
As preferably, keep last pressure that spring is formalized behind the die forming.Setting guarantees that spring repeatedly can not be out of shape after the bending to spring.
As preferably, the setting back is detected spring, mainly monitors the bending fatigue strength of spring, simultaneously the crooked critical number of times of detection springs and compare with design parameter.The fatigue strength of spring is the important parameter of bend pipe spring, and crooked critical number of times is the quality assurance of spring bending.
As preferably, detect defective work and then be sent to tempering furnace tempering and in this die forming and setting again, detect once more.
The invention has the beneficial effects as follows: spring can be processed into two end topers by die forming, the spring of intermediate cylindrical, and the steel wire of spring pressed and rectangular shape, meet design requirement, and guarantee the dimensionally stable of spring by setting, check and accept by detecting at last.
