Description
The present invention relates to spiral forming lined duct that is used for spiral lathe (Spiralling Machine) (Lined Pipe) of being stated in a kind of as corresponding principal right requirement and their method of finishing of being correlated with.
The present invention is applicable to the spiral lathe with a spiral forming head, and this spiral forming head is used for the shaping of the semi-finished product (for example wire rod is held in both hands material round piece or similar workpiece) from hot-rolled process.
The present technique state relates to the lathe that the metal wire rod that utilizes various diameters is made helix, and this lathe comprises a spiral forming swivel head with the pipe that forms helix.
In these lathes, the semi-finished product from the rolling production line are introduced in the pipe of spiral forming head with suitable pay-off.
No matter when the metal wire rod that is smooth or coarse projection passed through the spiral forming head, rotatablely moving of spiral forming head made the relational coiling forming tube bear powerful stress, this may jeopardize its structural integrity and/or original geometry.
When metal wire rod passed through, these stress appended on the tangential thrust of metal wire rod, have caused Frotteurism, therefore produced abrasion, at the inside of pipe abrasion especially severe.
Because it is uneven that pipe abrasion, lathe become, when retubing, lathe is balance again.
For this reason, the spiral forming pipe of spiral forming head obtains in such a way: under some operating condition, the spiral forming pipe with have auxiliary element that high anti-friction decreases characteristic and be made of one and add lining.
Though this solution guarantees the service life that spiral forming pipe is long, therefore same less intervention it.But because its very complicated structure and the fact that can not partly change have also just caused and the relevant problem of high cost of purchasing and repairing.
U.S. Pat-A-4.074.553 proposes to use anti-friction to decrease the tubular insert of putting into and be clamped in spiral forming pipe inside that material is made, these tubular inserts have the adjacent projection and the projection of self-centering on its outer surface, this just allows they are installed mutually accordingly, so that limit the transmission passage of metal wire rod in the spiral forming pipe.
Comprise that on the outer surface these anti-frictions of projection and groove decrease the special shape of inserts, and, all relate to high manufacturing and assembly fee and use for obtaining the special shape of the corresponding front-end and back-end that connect mutually.
In addition, be used for to reach the degree that allows above-mentioned groove and projection to exist, so the longitudinal size of these inserts can not be less than inserts self being installed in the spiral forming pipe and certain value of generation problem.
In addition, the passage that inserts limits a kind of segmented is installed, this passage is not that the helix that is particularly suitable for pipe forms.
In addition and since in changing the inserts process must with the spiral forming pipe or even pipe and relevant swivel bearing disassemble, thereby considerable problem can take place in this solution.
In addition, the special and concrete shape of inserts hinders its interchangeability.
Therefore, change or finishing operation costliness, time length and effort, cause the long-time interruption and the very big cost of spiral forming operating process simultaneously, in addition, because dismounting and installation spiral forming pipe are extremely complicated, so these operations must be finished by many workmans.
Therefore, the applicant design, test and implemented the present invention, with the shortcoming that overcomes state of arts and obtain further advantage.
The present invention states in corresponding principal right requires and represents its feature, and dependent claims are described the modification of the notion of main embodiment.
The objective of the invention is provides a kind of spiral forming lined duct for simple, better function and practical spiral lathe, and its allows finishing fast and has therefore limited the reduction of cycle-index and greatly reduced expense.
Another object of the present invention is make embedding/taking-up lining easy and simple to handle, allows it to be finished separately by a workman.
The another one purpose is to obtain a kind of anti-friction of being made up of the inserts of single type, small size and simple shape to decrease lining, therefore can obtain economically, can adapt to the formation of the helix shape of spiral forming pipe simultaneously.
A further object of the invention can be rotated inserts exactly randomly, under the situation of not changing inserts self, repeatedly obtains to transmit resetting of passage, even resets more than 10 times simultaneously.
The anti-friction of forming pipe insert according to the present invention decreases inserts and in fact is made of with the ring-type element that the spiral forming bore matches an external diameter, and inserts must be packed in the spiral forming pipe, and it reduces internal diameter and matches with the diameter of metal wire rod.
The endoporus that anti-friction decreases inserts has first connection or lead-in portion and second portion, actual column part.
The outer surface that these anti-frictions decrease inserts is actually columniform, make its manufacture process very simple, making insertion/taking-up simultaneously, they are very easy, in addition, the reduction longitudinal size that anti-friction decreases inserts can change between 20 millimeters to 40 millimeters, desirable for simplicity 30 millimeters, this reduction longitudinal size makes it to have the utmost point and is suitable for the characteristic that spiral forming pipe helix shape forms.
The increase of these adaptability features is actually because the sphere or the camber line profile of inserts front end face causes, and this profile can be settled inserts in the mode of Continuous Contact, even at the arch section of spiral forming pipe.
According to the present invention, the inlet of the inlet of spiral forming pipe and first anti-friction damage inserts endoporus communicates.
According to the present invention, anti-friction decreases inserts by means of a flexible cable element or an identical or like embedding spiral forming pipe, and therefrom takes out by it.
The corresponding at least one end of this flexible cable element has the device of temporary transient clamping inserts.
According to the present invention, in order under the situation of not changing inserts, to make the transmission channel reset, take out inserts by means of flexible cable element, make them around the rotation at random of flexible cable element do, and then they are embedded again; By a kind of like this method established privileged way is removed, simultaneously transmitting channel reset to optimum state.
In one embodiment of the invention, corresponding first end, cable element have an energy and throw off the clamping device that cooperates with the inserts front end face from cable element self, and corresponding second beginning, the cable element has a clamping device that contacts with the inserts endoporus.
In one embodiment of the invention, by successively with the inserts of requirement through introducing lining on the cable element because they are clamped at first end of cable element, therefore can from above-mentioned clamping device, not withdraw from.
Then, second end of cable element is introduced from the outlet of spiral forming pipe, come out up to inlet from this pipe.
In the time of in all inserts are in the spiral forming pipe, but the disengagement type clamping device is removed and cable element itself is extracted out from the spiral forming pipe from the cable element.
Then, the inserts clamping device is introduced in the outlet of corresponding spiral forming pipe, thus inserts be clamped at clamping device and with abutment means that the spiral forming tube inlet links to each other between.
The taking-up of inserts from the spiral forming pipe is to insert inlet by first end with the cable element, comes out from the outlet of spiral forming pipe up to it.By first end of pulling cable element, the clamping device of second end just enters with the endoporus of first inserts and contacts; Therefore other all inserts are pulled to the outside of spiral forming pipe with all to be clamped in first inserts on the cable element.
