Description
Technical field
The present invention relates to industrial furnace heating radiation pipe production technical field, particularly to a kind of heating radiation pipe shell
Former and forming method.
Background technology
The structural representation of heating radiation pipe of industrial furnace as shown in Figure 1, it includes by heating alloy resistance wire, pottery
What porcelain partition and extraction electrode were constituted heats assembly 20 and is set in heating radial canal shell 10 outside assembly 20, described
The diameter of shell 10 is typically 60～110mm, and thickness 2mm～5mm, length is at 1m～3m, it addition, this shell needs high temperature resistant
And heat conductivility needs are the best, its material is usually the high temperature alloy or heat-resisting alloy material, price smelted by precious metal
Much more expensive.Owing to being affected, without this type of seamless tubular goods on market by material technology and batch.Traditional band steel roll pipe forming machine
Being suitable for the formation of tubes that batch is bigger, the radial canal shell cost little for production quantity is the highest, so needing special
Formation of tubes equipment, currently used former is a kind of three-roll formation equipment as shown in Figure 2, uses manual charging,
Owing to the requirement of this tubing is higher, diameter is little, and length is long, and sheet material is relatively thick, and diameter, sheet metal thickness and length have one
Fixed proportion requirement, three-roller forming machine cannot roll-forming.
Summary of the invention
In view of problem present in existing heating radiation pipe shell molding, it is an object of the invention to provide a kind of heating spoke
Penetrate pipe shell former and forming method, be suitable for the formation of tubes of the valuable sheet material of small lot.
To achieve the object of the present invention, a kind of heating radiation pipe shell former of the present invention includes plant bottom case, if
Putting the mould die shoe on plant bottom case, the upper mold coordinated with die shoe, described upper mold is connected by moving with power-equipment
Power equipment drives and moves up and down, and described die shoe is provided with formation of tubes portion, and described formation of tubes portion is circular arc type, described circle
The diameter of arc is identical with the diameter of pipe fitting.
Preferably, the formation of tubes portion that described die shoe is arranged is provided with multiple, the radiation of the most corresponding different size
Pipe shell.
Further preferably, described formation of tubes portion is 1/3rd to quadrant, and the width w of described upper mold is shell
25% to the 60% of pipe fitting diameter.
According to another object of the present invention, the forming method of a kind of heating radiation pipe shell of the present invention includes walking as follows
Rapid:
According to pipe fitting specification to be processed, above-mentioned former is installed；
Start the power-equipment switch of former；
Sheet material is put into when upper mold is mentioned the formation of tubes portion on die shoe, and charging is the 10%-of strip width every time
15%；
After charging 40%-45%, sheet material being turned direction, starts to feed molding from another side, charging is sheet material width every time
The 10%-15% of degree；
Molding is stopped after combined feed 80%-90%；
Semi-finished product pipe fitting is put to pipe fitting welding equipment, while final step formation of tubes, carries out butt seam welding
Connect.
The heating radiation pipe shell former of the present invention, uses gradual feeding manner to carry out the progressively one-tenth of pipe fitting
Type, production efficiency is high, and the pipe fitting quality of processing is high, has substantially stopped the appearance of waste product, is especially suitable for the plate that batch is little and expensive
Material formation of tubes.
Accompanying drawing explanation
By detailed description below in conjunction with the accompanying drawings, the aforesaid objects, features and advantages with other of the present invention will become
Obviously.Wherein:
Fig. 1 show the structural representation of industrial furnace heating radiation pipe；
Fig. 2 show the former structural representation of current heating radiation pipe shell body；
Fig. 3 show upper mold and the cross section structure of die shoe of the former of the heating radiation pipe shell body of the present invention
Schematic diagram；
The change of shape schematic diagram of workpiece in the moulding process step of the heating radiation pipe shell that Fig. 4 show the present invention.
Detailed description of the invention
The upper mold of the former of the heating radiation pipe shell body of the reference present invention shown in Fig. 3 and the cross section of die shoe
Structural representation, described former includes plant bottom case (not shown), the mould die shoe being arranged on plant bottom case
100, the upper mold 200 coordinated with die shoe 100, described upper mold 200 is connected with power-equipment (not shown) and is driven by power-equipment
Moving up and down, described die shoe 100 is provided with formation of tubes portion 110, described formation of tubes portion 110 is circular arc type, described circle
The diameter of arc is identical with the diameter of moulding pipe.
One preferred embodiment in, the formation of tubes portion that described die shoe is arranged is provided with multiple, respectively correspondence
The radial canal shell of different size, in actual applications, for different calibers, it is only necessary to by lower module adjustment direction, as
This can save equipment cost.
In another preferred embodiment, described formation of tubes portion is 1/3rd to quadrant, described on
The width w of mould is 25% to the 60% of shell pipe fitting diameter.
The shape of workpiece in the moulding process step of the heating radiation pipe shell of the present invention shown in (a)-(f) of reference Fig. 4
Shape change schematic diagram, the forming method of described tube-like envelope comprises the steps:
Select formation of tubes portion and the upper mold of suitable die shoe according to the pipe fitting specification that need to process, former is installed
Good；
Start the power-equipment switch of former；
Sheet material is put into when upper mold is mentioned the formation of tubes portion on die shoe, and charging is the 10%-of strip width every time
15%；
After charging 40%-45%, sheet material being turned direction, starts to feed molding from another side, charging is sheet material width every time
The 10%-15% of degree；
Molding is stopped after combined feed 80%-90%；
Semi-finished product pipe fitting is put to pipe fitting welding equipment, while final step formation of tubes, carries out butt seam welding
Connect.
It should be noted that (a) of Fig. 4-(f) be only exemplary explanation pipe fitting in forming process along with progressively
The structure change fed and occur, does not implies that the step of the actual molding of the present invention, it is true that in actual production, permissible
Amount that size according to pipe fitting and pipe forming precision set feed every time and the number of times of total co-fed molding, this is not made by Fig. 4
Limit.
In above-mentioned former, it is smaller that the width w of upper mold can design, so, after this equipment molding
The seam of semi-finished product pipe fitting also can be smaller, compares and beneficially carries out last splicing and welding finally by welding equipment；Width w mistake
Little meeting causes time of formation of tubes elongated, and user can make corresponding balance according to practical situation and adjust.
The invention is not limited in described embodiment, those skilled in the art is in the spirit without departing from the present invention i.e. public affairs
In the range of opening, still can make some revise or change, therefore the scope of the present invention with claims limit in the range of
Accurate.
