Background technique
Currently, traditional electrothermal tube processing process are as follows: heating wire processing, fill out powder, the draw, Che Guan, dig powder, cut stick,
Bend pipe.The product that existing draw process is produced will appear the inconsistent problem of pipe range, and main cause is every product
Filling out powder density can be variant, and the elongation percentage of every root canal can be variant etc., behind just will increase vehicle plumber sequence for pipe vehicle at consistent
Length also needs to increase and digs the magnesia powder removal that nozzle is extra of powder process.That a part of length that this process requirement vehicle is gone, leads
Waste of raw materials is caused, and vehicle pipe and digging powder process have dust pollution, seriously affect environment.
Summary of the invention
In order to avoid with solve above-mentioned technical problem, the invention proposes a kind of electric heating pipe processing techniques.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of electric heating pipe processing technique, comprising the following steps:
Step 1: heating wire is mounted on and draws on stick and carry out spot welding by heating wire processing；
Step 2: filling out powder, and rubber plug structure used in powder process is filled out in change, increase draw on rubber plug between stick and nozzle climb electricity away from
From, then use powder filler that heating wire is penetrated blank pipe and fills closely knit magnesia powder between the two；
Step 3: riveting, it is close to connect rubber plug and electrothermal tube by nozzle rubber plug and electrothermal tube riveting at hexagon；
Step 4: stretching, using riveting die set by nozzle rubber plug and electrothermal tube riveting at hexagon, so that rubber plug and electrothermal tube
Close connection；
Step 5: cutting stick, and eduction rod is cut into consistent protruded length；
Step 6: electrothermal tube is curved regulation shape using bending machine and reaches the size requirement of drawing by bend pipe.
Further, the electrothermal tube riveting is the 80% of electrothermal tube caliber at the across flats of hexagon.
Further, the width that the electrothermal tube rivets in itself axial direction is 6mm.
The beneficial effects of the present invention are: the present invention is riveted the Plastic cap at both ends by increasing riveting die set after filling out powder
Securely, then with stretching-machine electrothermal tube is pulled into the same length, eliminates the draw, Che Guan, digging powder when the processing of traditional electrothermal tube
Technique overcomes traditional handicraft caused the shortcomings that wasting material, dust polluting environment, has and simplify processing step, improve and add
The advantages of work efficiency rate.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the configuration diagram of conventional rubber plug in the present invention；
Fig. 2 is the configuration diagram of rubber plug after improving in the present invention；
Fig. 3 is the upper die structure diagram of riveting die set in the present invention；
Fig. 4 is the lower die structure diagram of riveting die set in the present invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
A kind of electric heating pipe processing technique, comprising the following steps:
Step 1: heating wire is mounted on and draws on stick and carry out spot welding by heating wire processing；It specifically includes:
1, with spiral filament forming machine by heating wire wound into spring shape, reach defined wrapping wire outer diameter and resistance requirement；
2, the greasy dirt on heating wire surface is cleaned up by supersonic wave cleaning machine, and is put into baking oven and carries out at drying
Reason；
3, draw bastinade by under by automatic gluing plug machine to enter in the inner hole with micelle, reach defined protruded length；
4, heating wire is through using automatic wire feeding machine and draws stick threading position up and down, and full inspection is carried out to threading resistance and reaches electricity
Resistance requires；
5 are fixed heating wire with the progress spot welding of stick junction is drawn using percussion welder, reach the firmness of requirement.
Step 2: filling out powder, and rubber plug structure used in powder process is filled out in change, as shown in Figure 1 and Figure 2, increase draw on rubber plug stick with
Creepage distance L between nozzle, then heating wire is penetrated into blank pipe and fills closely knit magnesia powder between the two using powder filler.
Step 3: riveting is made by the field riveting mold on punching machine by nozzle rubber plug and electrothermal tube riveting at hexagon
It obtains rubber plug and electrothermal tube is closely joined together；
As shown in Figure 3, Figure 4, the riveting die set includes upper mold 1, the lower die 2 with the cooperation of upper mold 1；
The upper mold 1 includes upper mold core 11, the die shank 12 for being fixed on 11 top of upper mold core, and the bottom of the upper mold core 11 is set
There is No. 1 dovetail groove 11a；The lower die 2 includes pedestal 21, the lower mold core 22 being fixed on pedestal 21, the top of the lower mold core 22
Portion is equipped with No. 2 dovetail grooves 22a, No. 2 dovetail groove 22a and No. 1 dovetail groove 11a cooperation constitutes hexagon.
The electrothermal tube riveting is the 80% of electrothermal tube caliber at the across flats of hexagon, and the electrothermal tube is axial along itself
The width of upper riveting is 6mm.When riveting, the nozzle of electrothermal tube is by circle riveting at hexagon.
Step 4: it stretches, electrothermal tube both ends is placed on stretching-machine, the length of needs is stretched to by oil pressure.
Detailed process are as follows: electrothermal tube is put into the fixture of stretching-machine, starts start button, machine grip holder oil cylinder is stretched and starts
The tube head at electrothermal tube both ends is clamped in movement, and the oil cylinder for clamping post-tensioning in place starts to act, and is stretched to electrothermal tube, until
It completes to stretch operation after being stretched to the length of setting.
Wherein preferred, the oil pressure pressure of stretching is set as 6~10MPa, the elongation control of stretching 15%~20%,
