Technical field
The utility model relates to a kind of air-cushion eject-rod that is used for press machine.
Background technology
The variation of the impulse stroke that requires owing to moulds such as stretching die, sizing dies in the press machine at present; and old pressing equipment does not have the situation such as non-adjustable of air cushion stroke; usually can require to be equipped with the air-cushion eject-rod of many group different lengths; existing air-cushion eject-rod is whole rod member; therefore need to make the air-cushion eject-rod of many group specification length; and the manufacturing cost of the air-cushion eject-rod of every group of specification length is not low; even the air-cushion eject-rod of same size length; when in debugging, the inconsistent phenomenon of air-cushion eject-rod height occurs, will take a long time and adjust.
The utility model content
Technical problem to be solved in the utility model is: a kind of air-cushion eject-rod that is used for press machine that reduces manufacturing cost, improves installation effectiveness is provided.
Solve this technical problem, the technical solution of the utility model is: a kind of air-cushion eject-rod that is used for press machine, it is made up of basic bar, adjusting rod and the load spare more than three, the top of described basic bar is provided with basic bar screwed hole, the bottom of this base bar screwed hole has passage, described adjusting rod is formed by the adjusting rod body with the adaptive adjusting rod thread segment of basic bar screwed hole, and adjusting rod is provided with the adjusting rod tapped through hole of placement load spare uniform on the concentric circles identical with load number of packages amount.
Be provided with packing ring between the upper surface of described basic bar and the adjusting rod body.
Described load spare is the bulb plunger, and it is made up of bulb piston body, elastomeric element, adjustment ring and bulb.
Described elastomeric element is the compression spring.
The top of described adjusting rod has inner hexagonal hole, the side of having, described basic bar side platform.
The quantity of described bulb plunger is four.
A kind of air-cushion eject-rod that is used for press machine of the utility model adopts such structure, the basic bar that the air-cushion eject-rod of many group specification length has general fixed size, the haul distance of air-cushion eject-rod can be regulated by adjusting rod or adjusting rod and packing ring and be obtained, and the length of basic bar is shorter, so promptly reduced the manufacturing cost of air-cushion eject-rod, also reduced the management cost of placing air-cushion eject-rod, avoid the air-cushion eject-rod of prior art to take a long time simultaneously and adjusted, improved installation effectiveness.
