High-frequency straight seam welded pipe forming machine is the visual plant of manufacturing big-and-middle-sized straight seam welded steel pipe, and it take steel plate as raw material, can fast steel plate rolling be become to steel pipes with straight, completes the moulding sizing of steel pipe.This machinery requirement is according to the specifications vary of Steel Pipe Design, more mold exchange.Because the length of steel pipe is generally all longer, need the mould changed more, and mould also to assemble at every turn, location, regulates height and spacing.So change, mould often requires a great deal of time, manpower, and the installation quality of mould is also not easy to guarantee.Therefore, need to develop a kind of device of quickly replacing mould, to improve die change speed, enhance productivity, guarantee better mould installation quality.
Summary of the invention
To the object of the invention is in order solving the problems of the technologies described above, to propose a kind of high-frequency straight seam welded pipe die forming machine fast replacing device, this device adopts simple and quick syndeton, can integrally lift more mold exchange, work efficiency improves greatly, reduces labour intensity, guarantees better the quality that mould is installed.
The present invention is by the following technical solutions:
High-frequency straight seam welded pipe die forming machine fast replacing device, it is characterized in that: be provided with main connector, this main connector is provided with base, on this base, be provided with gantry bracing frame, in the middle of this bracing frame, be sequentially provided with from bottom to up step, top chock, Horizontal machine cap, under described, the power transmission shaft of conduction power before and after being equipped with in the middle of top chock, be lower drive shaft and upload moving axis, the front end of these two power transmission shafts is connected with two flexible power transmission shaft rear ends of high-frequency straight seam welded pipe forming machine by connecting axle pair respectively, the rear end of these two power transmission shafts respectively front end of two corresponding trunnion axis of the set of molds by clutch and high-frequency straight seam welded pipe forming machine connects, the Horizontal machine cap of support frame as described above upper end is provided with adjustment worm and gear, this adjusts the rear end of worm and gear and the corresponding adjustment worm and gear of described set of molds connects, in the middle of described Horizontal machine cap, be provided with the adjusting screw of erectting up and down, this adjusting screw and the engagement of described adjustment worm gear, its lower end and described top chock are hinged, and top chock can move up and down with adjusting screw, below described base, be also provided with in addition slide rail, the front end of base is connected with the piston rod of a cylinder, base be connected main body and can before and after piston rod is on slide rail, slide.
The present invention further improves and the additional project of enforcement is:
Before described clutch, be provided with contraposition spring, in order to the docking between trunnion axis.
High-frequency straight seam welded pipe die forming machine fast replacing device of the present invention, in use, first upper and lower trunnion axis is disconnected from the rear end of front end and described flexible power transmission shaft, the trunnion axis up and down of the set of molds front end that will change and the trunnion axis up and down of this device disconnect at clutch place, again the worm screw of depressing of upper end is disconnected, so set of molds integral body can be hung to forming machine.Then by the set of molds integral hoisting that will load onto assembling in advance on this fast replacing device side, the trunnion axis up and down of this device is connected with the trunnion axis up and down of set of molds, again the worm screw of depressing of upper end is connected, by adjusting screw, regulate the position of top chock and upper trunnion axis, complete the replacing of mould.Moving forward and backward of this fast replacing device can easily be carried out by cylinder.
Beneficial effect of the present invention:
1, simple in structure applicable, easy for installation, use easy and simple to handle;
2, greatly shorten the die change time, reduce labour intensity;
3, improve work efficiency, particularly can guarantee the installation quality of mould, guarantee precision;
4, reduce production costs, machine at most platform is used.
Accompanying drawing explanation
Fig. 1 is side-looking sectional structure schematic diagram of the present invention;
Fig. 2 is side-looking contour structures signal of the present invention;
Fig. 3 is the structural representation of facing of main connector of the present invention.
Profile of the present invention is not subject to the restriction of this figure, and only the change of profile also belongs among the protection domain of this patent.
The specific embodiment
Below in conjunction with accompanying drawing and example, the present invention will be described: embodiment: referring to accompanying drawing, high-frequency straight seam welded pipe die forming machine fast replacing device, it is characterized in that: be provided with main connector, this main connector is provided with base 5, on this base, be provided with gantry bracing frame 9, in the middle of this bracing frame, be sequentially provided with from bottom to up step 8, top chock 7, Horizontal machine cap 32, under described, the power transmission shaft of conduction power before and after being equipped with in the middle of top chock, be lower drive shaft 30 and upload moving axis 29, the front end of these two power transmission shafts respectively by connecting axle to 35, 34 with two flexible power transmission shafts 2 of high-frequency straight seam welded pipe forming machine, 1 rear end connects, the rear end of these two power transmission shafts is respectively by clutch 22, 21 trunnion axis 43 corresponding with two of the set of molds of high-frequency straight seam welded pipe forming machine, 42 front end connects, the Horizontal machine cap 32 of support frame as described above upper end is provided with adjusts worm and gear 33, this adjusts the rear end of worm and gear and the corresponding adjustment worm and gear of described set of molds 41 connects, in the middle of described Horizontal machine cap, be provided with the adjusting screw 31 of erectting up and down, this adjusting screw and the engagement of described adjustment worm gear, its lower end and described top chock are hinged 7, and top chock can move up and down with adjusting screw, below described base, be also provided with in addition slide rail, the front end of base is connected with the piston rod 6 of a cylinder 3, base be connected main body and can before and after piston rod is on slide rail, slide.Before described clutch, be provided with contraposition bullet (3).
