Abstract
The invention discloses a parallel extrusion automatic coiling production process for a stainless steel section pipe. The process comprises the following steps of: A, preparing a plate strip; B, performing parallel extrusion to form an embryonic pipe, namely conveying the plate strip to a pipe making machine by using a conveying machine, and performing nine-pass extrusion of two sides and upper and lower mould wheels on the plate strip in the horizontal state to automatically coil into the embryonic pipe during conveying; C, welding, namely automatically welding seams of the embryonic pipe by using a direct-current argon arc welding machine; D, cooling; E, performing smooth modification; F, cutting; G, finishing an end part; H, waxing and polishing, namely feeding a formed pipe into an automatic polishing machine for operation, and performing fourteen-pass waxing and polishing of two sides and upper and lower polishing wheels on the formed pipe during conveying; and I, checking and accepting. According to the process, an extrusion mode of continuously extruding and automatically coiling the plate strip into the embryonic pipe is adopted, working efficiency is improved, defects of cracking, folding and layering are avoided, and the quality of a product is improved.
Description
Technical field
The present invention relates to a kind of production technology of bar section of stainless steel pipe.
Background technology
Along with the development of modern city construction and the raising of people's lives grade, the ironware goods of thick rust deposite contaminated environment are got by the stainless steel products of exquisite health gradually and are replaced.Stainless steel products is valued the mark for " environmental protection, luckiness, health ", has distinct smart refined life art style.Especially regional at the Delta of the Pearl River, east Guangdong Province, developed areas such as Fujian South Fujian Province, stainless application several times increase progressively, and for exploitation stainless steel industrial benefit, the huge market space are provided.In recent years; Along with the fast development that China's economic society is built, stainless consumption figure constantly increases, and wherein the demand of stainless steel tube enlarges equally day by day; Market is very huge; And present homemade stainless steel tube is in kind, specification, quality and quantitatively can't all satisfy the needs that its socialization is used; Especially the Southeastern Coastal Cities standardization is built, the municipal and environment-friendly facility, and industry and civil buildings, processing industry, road bridge protective railings etc., the application of stainless steel tube constantly enlarges, environmental benefit, economic benefit and social benefit development prospect are considerable.
The production technology of traditional bar section of stainless steel pipe, there is crackle in the bar section of stainless steel pipe that is processed, and is folding, the defective of layering, the bar section of stainless steel tube light cleannes that have are relatively poor, more coarse; In addition, the two ends of bar section of stainless steel pipe are vertical inadequately smooth with the steel pipe axis, also have burr.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the present invention is to provide a kind of parallel extruding of the bar section of stainless steel pipe that improves the quality of products to intervolve production technology automatically.
To achieve these goals, the technical scheme of the present invention's employing is:
The parallel extruding of bar section of stainless steel pipe intervolves production technology automatically, includes following steps: A, with the raw material stainless steel sheet strip by the design specification requirement, in the shear banding machine, cut and be slit into lath; B, carry to go up tuber to lath with conveyer, lath is with level on its both sides and up and down under the squeezing action power of mold wheel, intervolves automatically to become shape tubing; C, utilize the direct current argon arc welding machine to carry out seam to the shape tubing suture that becomes automatically; Tubing after D, the seam gets into immediately and carries out cooling processing in the clear water; E, cooled tubing are sent into tuber again, utilize the mold wheel that reaches both sides up and down that cooled tubing is smoothly modified processing, become typing tubing; F, typing tubing parallel entering automatic gauging frame in tuber, pipe cutting machine cuts into tubing the shaping pipe of certain length automatically; G, shaping pipe two ends external diameter are by the finishing of angle grinding machine smoothly; H, shaping pipe get into the operation of automatic polishing machine operation, utilize grinding wheel that shaping pipe is added wax polishing; Shaping pipe after I, the polishing detects examination.
Among the said step B, lath is in transport process, through both sides, nine roads and the extruding of mold wheel up and down.
In the said step e, cooled tubing is in transport process, through both sides, 14 road and the level and smooth modification processing of mold wheel up and down.
Among the said step H, shaping pipe in transport process, through both sides, 14 road and up and down the wax polishing that adds of grinding wheel handle.
Beneficial effect of the present invention: because production technology of the present invention, the stainless steel lath pushes and intervolves into automatically the squeeze mode of blank tubing continuously automatically in the motion of tuber; Not only improve operating efficiency, but also avoided crackle, folding; The defective of layering has improved the quality of product; Since utilize electric argon welding to carry out disposable seam, in the tubing flaring test, flawless and breach; The present invention makes brand names for further developing the outstanding product of China's national industry, creates good economic benefit, and the scale of social benefit and environmental benefit is worked continuously provides possibility, in addition; The series stainless steel pipe that the present invention produced can be widely used in urban operating mechanism, road bridge protective railings, industry and the decorations of people's building, steel structure net rack; Medicine equipment, car and boat manufacturing, household goods, petrochemical industry; Electric power supplies water, air feed industry, fields such as universal machine structural member.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further detailed description.
Fig. 1 is a process chart of the present invention.
The specific embodiment
As shown in Figure 1, the parallel extruding of bar section of stainless steel pipe intervolves production technology automatically, includes following steps:
A, lath preparation: the raw material stainless steel sheet strip by the design specification requirement, is cut in the shear banding machine and is slit into lath;
B, parallelly be squeezed into shape tubing: carry lath with conveyer and go up tuber, lath, through both sides, nine roads and the extruding of mold wheel up and down, intervolves automatically and becomes shape tubing in transport process with level;
C, seam: utilize the direct current argon arc welding machine to carry out seam to the shape tubing suture that becomes automatically;
D, cooling: the tubing after the seam gets into immediately and carries out cooling processing in the clear water;
E, the level and smooth modification: cooled tubing is sent into tuber again, in transport process, utilize both sides and up and down mold wheel cooled tubing is smoothly modified processing through 14 roads, become typing tubing;
F, cutting: typing tubing parallel entering automatic gauging frame in tuber, pipe cutting machine cuts into tubing the shaping pipe of certain length automatically;
G, end finishing: shaping pipe two ends external diameter is level and smooth by the finishing of angle grinding machine;
