Abstract

The invention discloses a double-station cast tube airtight machine comprising a chassis, which is characterized by also comprising two groups of support rolls symmetrically arranged on the chassis, a socket retaining wall arranged at the left side of the chassis, a bellmouth retaining wall arranged at the right side of the chassis, a socket pipe bending cylinder positioned on the socket retaining wall, a socket drain plug connected with the socket pipe bending cylinder, a bellmouth pipe bending cylinder positioned on the bellmouth retaining wall and a bellmouth drain plug positioned on the bellmouth retaining wall, wherein reinforcing ribs of the bellmouth retaining wall and the socket retaining wall are in the shape of double cross, and the strength is enhanced; and the socket drain plug is fixed through a socket drain plug fixed seat, and the fixing is more convenient and flexible. The invention can detect two cast tubes for once so that the production efficiency is greatly enhanced.

Description

The airtight machine of double cast tube

Technical field

The present invention relates to the airtight machine of a kind of double cast tube, belong to centrifugal ball milling cast carbon steel air tight test equipment.

Background technology

Centrifugal ball milling cast carbon steel need check whether leak gas, and the airtight machine that present inspection machine is used all is single station, once can only go up a cast carbon steel, and efficient is lower, because its efficient causes the cast carbon steel omission easily less than other equipment of same production line.And existing equipment insufficient strength usually when the bigger cast carbon steel of check diameter is prone to distortion and fault such as snaps, and its liftout attachment setting is also unreasonable, and the pipe bending cylinder at cast iron pipe bellmouth place is a cantilever force, and the cylinder bar is fragile.

Summary of the invention

The technical matters that the present invention will solve provides the airtight machine of a kind of double cast tube, and it can once check the impermeability of two cast tubes, and production efficiency improves.

For solving the problems of the technologies described above; The technical scheme that the present invention taked is: the airtight machine of a kind of double cast tube; It comprises the chassis; Its key is also to comprise two groups of backing rolls being located on the chassis, be located at the socket barricade in left side, chassis, be located at the right side, chassis the bellmouth barricade, be positioned on the socket barricade two socket pipe bending cylinders, through the affixed socket plug of socket plug holder and socket pipe bending cylinder, be installed on the bellmouth pipe bending cylinder on the bellmouth barricade and be installed on two bellmouth plugs on the bellmouth barricade; Socket plug holder comprises fixed head, is welded in the positioning boss on the fixed head and is installed on the claw on the fixed head that the socket plug is provided with the groove suitable with positioning boss.The fixed form of this socket plug is convenient flexibly.

Preferably, the cylinder bar on the above-mentioned socket pipe bending cylinder be provided with the cylinder head thread connection on the cylinder bar.

Preferably, above-mentioned bellmouth pipe bending cylinder is arranged in the middle of the two bellmouth plugs, and the stressed relatively balance of bellmouth pipe bending cylinder has reduced the generation of fault like this.

Preferably, the stroke of above-mentioned socket pipe bending cylinder is 700～1200mm.

Adopt the beneficial effect that technique scheme produced to be: the present invention designs for double, can once check two cast tubes, has improved production efficiency greatly; Further improve socket barricade and bellmouth barricade are designed to a meter font reinforcement, and the stress point during with its work moves on to both sides by the center, make barricade stressed evenly, intensity improves, and has reduced failure rate; The socket plug is fixed by socket plug holder, and is more convenient than former bolt; The bellmouth pipe bending cylinder changes force balance into by former cantilever force, greatly reduces the generation of fault.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.

Referring to accompanying drawing 1 and accompanying drawing 2; The present invention includes a chassis 7, be arranged with two groups of backing rolls 4 on the chassis 7, the left side on chassis 7 is provided with socket barricade 2; The front and back of socket barricade 2 are symmetrically installed with two socket pipe bending cylinders 1; Thread connection has cylinder head 14 on the cylinder bar 13 of socket pipe bending cylinder 1, and cylinder head 14 is welded by two parts, and cylinder head 14 connects with socket plug holder 15 through bolt.Socket plug holder 15 comprises a fixed head 15-1, on fixed head 15-1, is welded with positioning boss 15-2, and claw 15-3 also is installed on fixed head 15-1.Socket plug 3 is provided with the suitable groove with positioning boss 15-2, and positioning boss 15-2 forms concavo-convex the cooperation with socket plug 3, and then further fixing through claw 15-3.7 right side is provided with bellmouth barricade 6 on the chassis, in the middle part of bellmouth barricade 6 bellmouth pipe bending cylinder 8 is installed, and is provided with bellmouth plug 5 in the symmetria bilateralis of bellmouth pipe bending cylinder 8.

Referring to accompanying drawing 3, the similar rice of the shape of the reinforcement 17 of socket barricade 7 and bellmouth barricade 6 font, this reinforcement 17 is a diagonal bar arranged in a crossed manner.

The stroke of the socket pipe bending cylinder 1 among the present invention is that 700～1200mm is advisable, and the stroke of generally choosing 700mm can satisfy request for utilization.

During work, the height according to the specification of cast tube adjustment backing roll 4 is put into cast tube on the backing roll 4 through relevant device then; Socket pipe bending cylinder 1 promotes socket plug 3; Cast tube is moved to bellmouth plug 5 directions, then through the seal on socket plug 3 and the bellmouth plug 5 with the cast tube bore seal, pneumatics wind control system is filled the air of certain pressure to the cast tube inner chamber through the gas ducting on the socket plug 3; Then cast tube is moved on in the tank, can check cast tube whether to leak gas.
