Abstract
The utility model relates to a flange ring rolling mill, in particular to a flange ring rolling mill with a limit device, which solves the problem of dimension control of the flange ring rolling mill during ring rolling. The flange ring rolling mill comprises a rotating master mold on a worktable and a mandrel arranged under the master mold; a hydraulic oil cylinder is arranged above the rotating master mold; a piston rod of the hydraulic oil cylinder is connected with a main spindle box of the rotating master mold; a proximity rod is arranged on the main spindle box; the proximity rod is provided with a proximity switch connected with a control circuit; a screw rod of which the height can be adjusted is arranged below the proximity rod; and the screw rod is arranged under the proximity switch. Compared with the prior art, the flange ring rolling mill is additionally provided with the limit device consisting of the proximity switch, the proximity rod and the screw rod based on the prior device. The flange ring rolling mill has the advantages of reasonable design, sensitive control and high degree of automation.
Description
Technical field
The utility model relates to a kind of machine for rolling ring of flange, is specially a kind of machine for rolling ring of flange that has stopping means.
Background technology
Annular elements such as flange are widely used in the industry such as oil, chemical industry, metallurgy, at present, mainly still adopt open die forging to cause cake sheet, punching, saddle support reaming, rolling rolling to expand for the manufacturing forming technique of annular elements such as flange, are finally formed by machining again.It is at first to adopt saddle support reaming or Forgingother mode to carry out the annular element base that rolling rolling is expanded, then, on machine for rolling ring, adopt rotary die to the local pressure forming continuously of blank, the whole wall thickness of annular element is reduced, enlarged-diameter, cross section profile is shaped, and makes it become the annular element blank with simple shape and size, and then carries out the machining of cross sectional shape by large-scale vertical lathe.Existing machine for rolling ring tool is simple in structure, mainly comprises by main mould of the rotation of driven by motor and mandrel, and the flange blank is enclosed within on the mandrel, utilizes main mould of rotation and mandrel that ring is rolled in the extruding of flange.Control is accurate inadequately in the ring rolling process, can not adapt to the requirement of processing high-quality flange.The particularly control of flange when rolling the ripe value of ideal, if by artificial visually examine's control, obviously accuracy and steady quality can be very poor.
Summary of the invention
The utility model provides a kind of machine for rolling ring of flange that has stopping means for the problem of machine for rolling ring of flange size Control in ring rolling process of solving prior art and existing.
The utility model is realized by following technical scheme, a kind of machine for rolling ring of flange that has stopping means, comprise the main mould of rotation on the workbench, rotate the mandrel of the below of main mould, the top of rotating main mould is provided with hydraulic jack, and the piston rod of hydraulic jack is connected with the main spindle box that rotates main mould, on main spindle box, be provided with near bar, near bar be provided be connected with control circuit near switch, be provided with the leading screw that can regulate height near the below of bar, leading screw is positioned near under the switch.
Compared with prior art, the utility model has increased on conventional device by near switch, near bar, and the stopping means that leading screw is formed.When rotating the process that main mould rolls flange, the ring of flange directly diminishes, so main spindle box moves down gradually, the height of leading screw is that the ring according to flange directly preestablishes, when driving to move down to make near switch near bar, main spindle box presses when contacting leading screw, near switch activated control circuit is sent instruction, feed back to hydraulic system then, hydraulic jack is quit work.Reasonable in design, control is sensitive, the automaticity height.
