Technical field
The utility model relates to a kind of gutter ring finishing mold, relates in particular to a kind of locked groove ring for wheeled engineering machinery wheel finishing mold, belongs to technical field of engineering machinery.
Background technology
The manufacturing process of existing locked groove ring for wheeled engineering machinery wheel mainly contains two kinds, and a kind of is the hot rolling forming technology, and its technological process is: cut-out → heating → volume circle → manual welding welding → polishing → shaping; Only to the radial dilatation of gutter ring, the dimensional accuracy of gutter ring is subjected to the influence of shaped steel size and springback capacity big to trimming in this technology, makes the radial dimension of gutter ring can not get control and circularity, flatness is relatively poor.Another kind of manufacturing process is the cold coiling forming technology, and its technological process is compared with the hot rolling forming technology and removed heating process, and workpiece surface quality is improved to a certain extent, but the same above-mentioned shortcoming that exists of its trimming.
The utility model content
The purpose of this utility model provides the high locked groove ring for wheeled engineering machinery wheel finishing mold of a kind of product precision.
For realizing above-mentioned utility model purpose, the utility model adopts following technical scheme:
A kind of locked groove ring for wheeled engineering machinery wheel finishing mold comprises upper die body and lower mold body, and described upper die body comprises cylinder annular patrix, reaches the cope match-plate pattern of fixedlying connected with patrix, and the outside inferior horn of this patrix offers annular groove; Described lower mold body comprises lower module, and this lower module outwards fixedlys connected with slide block, touch with slide plate downwards, and described slide block and the feather key that is fixed on the outer ring are slidingly matched, and upwards fixedlys connected with back-up ring, fixedlys connected with lower bolster downwards in this outer ring; Described slide plate is connected with lower bolster elasticity downwards, and slide plate inwardly touches with the feather key that is fixed on the guide pillar; The angle offers annular groove on the inboard of described lower module, matches with the annular groove of patrix, forms the workpiece space.
Further, be provided with one deck backing plate between described slide block and the outer ring.
The relative spring groove that is provided with between described slide plate and the lower bolster, built-in spring.
The locked groove ring for wheeled engineering machinery wheel finishing mold that the utility model provides, when upper die body pressed down, patrix pressed down lower module, lower module passes through the relative feather key of slide block to lower slider, simultaneously, lower module is to pressing down slide plate, and slide plate moves down the compression spring up to contacting with lower bolster along feather key; The workpiece that patrix presses down in the annular groove makes the workpiece axial compression, and lower module moves down and makes workpiece radial contraction from outside to inside, be subjected to radial load and responsive to axial force simultaneously, excircle of workpiece size, flatness and circularity precision have been improved, make dimensional accuracy reach 0.3mm, flatness, circularity≤0.5mm have promoted product quality.
Description of drawings
Fig. 1 is the axial cutaway view of the utility model locked groove ring for wheeled engineering machinery wheel finishing mold.
The specific embodiment
In order to make those skilled in the art person understand the utility model scheme better, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the embodiment of the locked groove ring for wheeled engineering machinery wheel finishing mold that the utility model provides, comprise upper die body 10 and lower mold body 20, described upper die body 10 comprises cylinder annular patrix 110, reaches the cope match-plate pattern 120 of fixedlying connected with patrix 110, patrix 110 moves up and down with cope match-plate pattern 120, and the outside inferior horn of this patrix 110 offers annular groove.
Described lower mold body 20 comprises lower module 210, this lower module 210 outwards fixedlys connected with slide block 220, downwards and slide plate 230 touch, described slide block 230 is slidingly matched with the feather key 250 that is fixed on the outer ring 240, lower module 210 can move up and down along feather key 250 with slide block 220, simultaneously, lower module 210 can horizontally slip on slide plate 230; Upwards fixedly connected with back-up ring 260, fixedly connected with lower bolster 270 downwards in described outer ring 240, back-up ring 260 is fixed as one with outer ring 240, lower bolster 270, limits the removable space up and down of lower module 210; Described slide plate 230 is connected with lower bolster 270 elasticity downwards, and slide plate 230 inwardly touches with the feather key 290 that is fixed on the guide pillar 280, and slide plate 230 can slide up and down along feather key 290; The angle offers annular groove on the inboard of described lower module 210, matches with the annular groove of patrix 110, forms workpiece 30 die spaces.
Also be provided with the wear-resisting backing plate 225 of one deck between described slide block 220 and the outer ring 240, be used to prolong the service life of outer ring 240, reduce the manufacturing cost of mould.
