Abstract
The utility model discloses an internal pressure head structure of a vacuum hot-pressing furnace cylinder, which is characterized in that a cylinder is fixed on the top portion of a vacuum hot-pressing furnace, a piston rod of the cylinder is a hollow structure, the upper end of a pressing rod is sleeved in a piston rod, and the lower end of the pressing rod perpendicularly extends in the vacuum hot-pressing furnace to press work pieces. The periphery of the piston rod is sleeved with a corrugated pipe having sealing function. The cylinder is fixedly connected with the top portion of the vacuum hot-pressing furnace via a connection seat. The internal pressure head structure of the vacuum hot-pressing cylinder has the advantages of compact structure, and can save materials to the utmost extent.
Description
Technical field
The utility model belongs to mechanical field, relates to the built-in pressure head structure of a kind of vacuum hotpressing stove oil cylinder.
Background technology
Traditional vacuum hotpressing stove oil cylinder and pressure head structure as shown in Figure 1, hydraulic jack separates closed assembly with pressure head, need to increase independent oil cylinder fixed support, complex structure, processing cost height.
The utility model content
Technical problem to be solved of the present utility model provides the built-in pressure head structure of a kind of vacuum hotpressing stove oil cylinder, and this pressure head structure has the characteristics of compact conformation, can save material to greatest extent.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The built-in pressure head structure of a kind of vacuum hotpressing stove oil cylinder, it is characterized in that, be fixed with oil cylinder at the vacuum hotpressing stove top, the piston rod of this oil cylinder is a hollow structure, the upper end of depression bar is sleeved in the piston rod, and the lower end of this depression bar vertically puts in and pushes down workpiece in the vacuum hotpressing stove.
Described piston rod periphery is set with the bellows that seals.
Described oil cylinder is fixedlyed connected by connection seat with the vacuum hotpressing stove top.
The beneficial effect that the utility model had has:
The utility model has overcome traditional pressure head structure need increase independent oil cylinder fixed support, complex structure, shortcomings such as processing cost height.
The mechanical type of high vacuum furnace pressurization workpiece during structure of the present utility model is applicable to.Its design feature is as follows:
1, depression bar is built in the hollow piston rod, has saved the axial space size of structure greatly.
2, depression bar and furnace chamber rely on the bellows static sealing, and sealing reliability is good, is adapted to use at high vacuum furnace.
3, this structural design compactness, good looking appearance is generous.
Description of drawings
Fig. 1 is traditional pressure head structure schematic diagram;
Fig. 2 is the built-in pressure head structure schematic diagram of vacuum hotpressing stove oil cylinder.
The 1-bellows, 2-coupling seat, 3-furnace chamber, 4-depression bar, 5-piston rod, 6-oil cylinder, 7-workpiece, 8-body of heater.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 2, pressure-producing part is made up of two parts: hydraulic jack 6 and depression bar 4.Concrete structure is: be fixed with oil cylinder 6 at the vacuum hotpressing stove top, the piston rod 5 of this oil cylinder is a hollow structure, and the upper end of depression bar 4 is sleeved in the piston rod 5, and the lower end of this depression bar 4 vertically puts in and pushes down workpiece 7 in the vacuum hotpressing stove.Piston rod 5 peripheries are set with the bellows 1 that seals.Oil cylinder 6 is fixedlyed connected by connection seat 2 with the vacuum hotpressing stove top; Oil cylinder adopts hydraulic-driven, and when piston rod moved downward, piston rod drove depression bar and pushes down workpiece.
