Abstract
The utility model relates to a welding tube automatic pressuring machine, which is composed of a pressuring mechanism controlled by two sets of connected cylinders, a carriage pipe feeding mechanism controlled by two cylinders, and a pipe turning mechanism controlled by the cylinder. The simultaneous pressuring test of a plurality of welded pipes can be completed once. When the utility model is adopted, the pressuring speed is high, the on-line pressuring can be realized, and the fully automatic control of the pressuring mechanism, the carriage pirn feeding mechanism and the turning pipe mechanism can be realized, Thus, the labor intensity of a worker is abated.
Description
The utility model belongs to high-frequency welding steel pipe leak detection mechanical hook-up.
At present, suppressing leak test plant with the matching used welded tube of homemade ratio-frequency welded tube production unit is the single tube stamper.This stamper drives a head of suppressing that water valve is housed by a cylinder and forms, transmit steel pipe by being located at two chain-type cold beds of suppressing between the head, can only carry out bulge test to a root bead pipe at every turn, it is low to suppress speed, can not realize online suppressing (promptly can not be linked to be production line with unit realizes whole welded tubes of producing are suppressed by root), can only suppress equipment as off-line and use.Simultaneously, this stamper will lean on artificial supply bobbin and unload pipe, and labour intensity is bigger.
The purpose of this utility model is to provide a kind of welded tube automatic stamper, realizes once many welded tubes being suppressed simultaneously, improves and suppresses speed, makes it to realize the online production of suppressing; Simultaneously, supply bobbin and unload pipe alleviates labor strength automatically.
The automatic stamper of the welded tube that the utility model provides is made of three parts, promptly suppresses mechanism, pirn feeding mechanism and turns over pipe mechanism.Wherein suppress mechanism and comprise the conjuncted cylinder of two opposite groups, each cylinder wherein has a hollow piston bar, its front end is suppressed head, the rear end is connected with a withstand voltage water vat respectively by high-pressure rubber pipe, one of them withstand voltage water vat connects a pneumatic draining valve, another withstand voltage water vat connects a pneumatic water intaking valve respectively and connects a pressurized cylinder by a conjuncted water vat, is provided with one group of transversely arranged end and is fixed on welded tube supporting plate on the frame between two groups of conjuncted cylinders, and supporting plate top is provided with the welded tube locating slot; Pirn feeding mechanism wherein comprises the car body that stroke cylinder and control thereof move forward and backward, the vehicle body upper portion two ends are separately installed with jack-up cylinder and guidepost, carriage is being fixed in this cylinder and guidepost upper end, one group of transversely arranged riser of fixed installation above the carriage, and the riser end face is provided with the welded tube locating slot; The pipe mechanism of turning over wherein comprises the axis that turns over pipe cylinder and control thereof, and one group of height of fixed installation is lower than the turnover panel of said welded tube supporting plate on the axis.
The automatic stamper of this welded tube all adopts pneumatic control, can adapt to situ flow torrent wet trade environment.Its operational process is under electric programmed control, the welded tube that the car body of pirn feeding mechanism is produced preceding working procedure under stroke cylinder and jack-up cylinder action holds up by said riser, delivers to the welded tube supporting plate correspondence position of suppressing mechanism, and carriage descends, welded tube is fallen on the supporting plate, and car body returns; Under conjuncted cylinder action, suppress simultaneously head welded tube clamped, suppress head because each cylinder of conjuncted gas tank is controlled one respectively, thus suppressing of driving of its each piston rod head moves can be asynchronous, this has just solved the welded tube difference in length and has pressed from both sides not tight problem.After suppressing the tight welded tube of head-clamp, pneumatic water intaking valve is opened to withstand voltage water vat water-filling, and pass through high-pressure rubber pipe, the hollow piston rod makes water charge into every root bead pipe, and communicates with the other side's withstand voltage water vat, thereby is full of bulge test when pressurized cylinder is finished many root beads pipe by conjuncted cylinder to the pressurization of whole water route behind the water, the bulge test pneumatic draining valve that finishes is opened, water is got rid of, welded tube is turned over away turning under the pipe cylinder action turnover panel upset then, turnover panel returns and resets then.So far, the machine run one-period enters the next one then and suppresses the cycle.If with the above-mentioned jack-up of this stamper, fortune pipe, water-filling, supercharging, voltage stabilizing with turn over the pipe time be set for 1,5,8,3,5,1 second respectively, suppress totally 23 seconds cycle for one, finishing an assembly welding pipe suppresses, the speed of suppressing obviously improves than the single tube stamper, existing homemade welded tube mill assembly welding pipe speed of production be 60-80 rice/minute, be equipped with the automatic stamper of four pipes and can realize online suppressing, whole process from supply bobbin, suppress and turn over all control automatically of pipe discharging, alleviated working strength of workers greatly.
Accompanying drawing is depicted as an embodiment of the present utility model---and the structural representation of the automatic stamper of four pipes, two groups of conjuncted cylinders of this stamper are made up of four cylinders respectively.1 is the hollow piston rod of conjuncted cylinder among the figure, and 2 is conjuncted cylinder, and fixed in position is on support 21,3 for suppressing head, and 4 for turning over the pipe cylinder, is installed in the rear side of support 21,5 is the welded tube supporting plate, and totally 4, an end is fixed on the frame 8, the welded tube locating slot on its height and top thereof wants corresponding with suppressing a position, and 7 is axis, rotates by turning over 4 controls of pipe cylinder, fix one group of turnover panel 6 on it, 9 is withstand voltage water vat, and 10 is pneumatic water intaking valve, communicates with withstand voltage water vat, 11 is conjuncted water vat, the one end communicates with withstand voltage water vat, the piston of another termination pressurized cylinder 12, and 13 is guidepost, 14 is the jack-up cylinder, 15 is car body, and 16 is wheel, and 17 is guide rail, 18 is stroke cylinder, its piston links to each other with car body, and 19 is carriage, and 20 is riser, totally three, the welded tube locating slot on top is corresponding with the locating slot of aforementioned supporting plate 5, and 22 is pneumatic draining valve, and 23 is high-pressure rubber pipe.
