Description
Technical field
The invention belongs to field of mechanical technique, it is related to a kind of high-mechanic gate-type forcing press.
Background technology
Gate type hydraulic machine be applied to large, medium and small type enterprise, factory, industrial and mineral and Auto repair shop, heavy-duty machine, ring flange,
Belt pulley, neck bush, bearing dismantling operation, alignment correction, bending, with mold can punching, blanking, stretching, flanging substitution it is old
Formula spiral hand operated press carries out operation, and jack test can be carried out by loading onto pressure gauge.
Oil cylinder is fixed on the upper end of frame, the fixed form use of current oil cylinder and frame straight down in gate-type forcing press
Be mode that oil cylinder is directly threadedly attached in frame, because the casing wall of oil cylinder is relatively thin, in the case of high-mechanic oil cylinder with
Active force between frame is larger, it may appear that the casing wall deformation of oil cylinder causes the situation of the screw thread deformation on oil cylinder casing wall, causes
Oil cylinder can not be disassembled from frame, it is impossible to which oil cylinder is safeguarded；The pressure release of current oil cylinder is required to manual progress, operation
It is cumbersome, it is less efficient.
The content of the invention
The purpose of the present invention is there is above mentioned problem for existing technology, it is proposed that a kind of high-mechanic gate-type forcing press,
Present invention solves the technical problem that being energy releasing pressure automatically.
The purpose of the present invention can be realized by following technical proposal：
A kind of high-mechanic gate-type forcing press, including frame and the oil cylinder being fixed in frame, the oil cylinder include cylinder body, work
Stopper rod and fixed piston on the piston rod, one end of the cylinder body are fixed with end cap, it is characterised in that be located in the cylinder body
End cap inner seal is fixed with the through hole being provided with seal holder ring, the piston along the axis direction arrangement of piston rod, described logical
Provided with the steel ball that can block through hole in hole, push rod, the lower end energy of the push rod are provided with positioned at the lower end of steel ball in the through hole
The bottom surface protrusion of opposing pistons, during piston is moved down the lower end of the push rod can with seal holder ring against and cause described
Steel ball jack-up to be located on through hole insertion, the cylinder body by push rod is provided with relief hole between piston and seal holder ring, described logical
Kong Nengyu relief holes are connected.
Fluid during the downward punching press of the piston rod of oil cylinder in cylinder body acts on the upper end of steel ball so that steel ball blocks through hole,
Ensure that in-oil cylinder pressure is enough, it is to avoid occur, because oil liquid leakage causes the situation of insufficient pressure, stroke pole being reached in piston rod
The lower end of push rod can be with seal holder ring against push rod meeting opposing pistons are moved up and by steel ball jack-up, steel ball is by jack-up in limited time
Through hole is by insertion afterwards, and fluid can flow through through hole and be flowed out from relief hole, therefore the distress resolves that fluid is acted on piston, complete
The releasing pressure automatically of oil cylinder；The leakage of the fluid in pressure release is avoided by seal holder ring, it is ensured that the sealing of oil cylinder.
In above-mentioned high-mechanic gate-type forcing press, the through hole has two sections, respectively goes up oil-feed section fuel-displaced section with,
Fuel-displaced section of the diameter with diameter greater than under of the upper oil-feed section, fuel-displaced section of the diameter with diameter greater than under of the steel ball.Steel ball energy
With under fuel-displaced section of upper port edge recline by upper oil-feed section and under block between fuel-displaced section, in supercharging due to upper oil-feed section one
The pressure of side is larger, and steel ball can only abut in down fuel-displaced section of upper port edge, it is ensured that oil cylinder exports big pressure.
In above-mentioned high-mechanic gate-type forcing press, it is described under fuel-displaced section of middle part be provided with limited step, the push rod
Upper end has a position limiting convex ring, the position limiting convex ring can with limited step against.The structure is avoided that lower port of the push rod from through hole
Drop.
In above-mentioned high-mechanic gate-type forcing press, the seal holder ring includes seat ring body and relative seat ring body is raised
Boss, the inwall of the seat ring body and cylinder body recline and between seat ring body and the inwall of cylinder body be provided with sealing ring, it is described
The diameter of boss is less than the diameter of seat ring body, forms pressure-releasing chamber between the inwall of the boss and cylinder body, the relief hole with
Gap is connected.Ensure that fluid can be between seal holder ring and piston after through hole insertion space is flowed in proper order by the structure to let out
Press in chamber, then from pressure-releasing chamber flow to relief hole, the space of pressure-releasing chamber is larger, and the fluid that can be accommodated is more, thus can rapidly by
Pressure is laid down, and is then excluded fluid by relief hole, can rapid pressure release, the effect of raising pressure release by pressure-releasing chamber.
In above-mentioned high-mechanic gate-type forcing press, the lower edge of the endoporus of the seal holder ring is provided with resigning step, institute
State and sealing ring be cased with resigning step, be additionally provided with briquetting in the resigning step, the one side of the briquetting and sealing ring against,
The another side of the briquetting and end cap against.Make it that briquetting compresses sealing ring by the structure so that sealing ring and piston
Bar and seal holder ring are closely against raising sealing effectiveness.
In above-mentioned high-mechanic gate-type forcing press, the lower end of the cylinder body is threaded with mounting flange, the fixation
It is bolted between flange and frame.Cause the mounting flange can not be with cylinder even if deformation occurs in the casing wall of cylinder body when in use
Body is disassembled, and also oil cylinder can be taken off into realization maintenance by the way that mounting flange and frame are dismantled, it is ensured that the convenience that oil cylinder is safeguarded
Property.
In above-mentioned high-mechanic gate-type forcing press, the seal holder ring and end cap have in thread segment positioned at cylinder body
Side.Mounting flange is relative with seal holder ring and end cap, the casing wall of cylinder body is supported by seal holder ring and end cap, it is to avoid cylinder
The casing wall of body because active force is excessive and deformation.
Compared with prior art, this high-mechanic gate-type forcing press has the self-relieving advantage of energy.
