Abstract
The invention discloses an air-cushion eject-rod which adjusts the operational stroke of a die. The air-cushion eject-rod consists of a basal rod, an adjusting rod and more than three force bearing pieces. The top part of the basal rod is provided with a screwed hole for the basal rod, and the lower part of the screwed hole is provided with an air hole. The adjusting rod consists of an adjusting rod body and an adjusting rod thread section matched with the screwed hole. The adjusting rod is provided with thread through holes of the adjusting rod, which are used for accommodating the force bearing pieces; wherein, the thread through holes are distributed on a concentric circle and have the same number with the force bearing pieces. The air-cushion eject-rod which adjusts the operational stroke of the die adopts the structure that a plurality of groups of air-cushion eject-rods with regular length are provided with a universal basal rod with fixed size, and the operational stroke of theair-cushion eject-rod can be adjusted by the adjusting rod or the adjusting rod and a gasket, while the basal rod has small length, thus not only reducing the production cost of the air-cushion eject-rods, but also lowering the handling cost of the air-cushion eject-rods, simultaneously, the disadvantage that the air-cushion eject-rod in the prior art spends a long time on adjusting is avoided, and the mounting efficiency is improved.
Description
Technical field
The present invention relates to mould, relate in particular to a kind of air-cushion eject-rod of adjusting the mold work stroke.
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, 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 the inconsistent phenomenon of air-cushion eject-rod height occurs when in debugging, will take a long time and adjust.
Summary of the invention
Technical problem to be solved by this invention is: a kind of air-cushion eject-rod that reduces manufacturing cost, improves the adjustment mold work stroke of installation effectiveness is provided.
Solve this technical problem, technical scheme of the present invention is: a kind of air-cushion eject-rod of adjusting the mold work stroke, 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 of adjusting the mold work stroke of the present invention 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.
