Abstract
The utility model relates to a hammer guideway of a NC full hydraulic forging hammer used for a full hydraulic forging hammer employing the numerical control technology, which includes a hammer head, a hammer guide rail disposed at the lateral side of the hammer head, wherein, the profile of the hammer guideway is X-shape, i.e. the guide surfaces of the guide rail are inclined planes and are arranged in a catercorner manner. The hammer will radially expand along the radial direction when being heated. The X-shape structure of the guide rail can be specifically described like following: two guide slots are set on both sides of the hammer head, and the front and rear guide surfaces of the guide slots are inclined planes. The X-shape structure will radially expand along the radial direction when the hammer head is heated, so guide clearance will not diminish when the hammer head is heated, because the hammer guide rails will not deform under the temperature changing, and then the clearance of the guide rail can be set very small, therefore, the forging accuracy of the NC full hydraulic forging hammer is high, and the utilization ratio of the forging material is also very high.
Description
Technical field
The utility model belongs to the forging equipment technical field of metal forming, relates in particular to a kind ofly utilizing the tup guide rail of the digital complete hydraulic die forging hammer that uses on the complete hydraulic die forging hammer of Numeric Control Technology.
Background technology
Domestic existing die hammer tup guide rail all is the comb shape guide rail, and it has the arm of force short, not temperature compensated shortcoming.In order not make tup stuck because of the expansion that heats up causes the guide clearance minimizing, have to strengthen the cold conditions gap of guide rail, this also is the reason that is difficult to carry out precision die forging on the present domestic die hammer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of guiding accuracy height, guide clearance not to be subjected to the tup guide rail of the digital complete hydraulic die forging hammer that temperature rise influences.
Technical solution of the present utility model is: comprise tup, be arranged on the tup guide rail of tup side, the tup guide rail is " X " shape guide rail structure.Described " X " shape guide rail structure is meant that the spigot surface of guide pass is the inclined-plane.
And the spigot surface of tup guide rail is diagonal to be arranged, is the radial radiation shape when tup is heated and expands.
Simultaneously, described " X " shape guide rail structure is meant specifically on the tup two sides and has gathering sill that the spigot surface before and after the gathering sill is the inclined-plane.This " X " shape guide rail structure is the radial radiation shape and expands when tup is heated.Just can not reduce the guiding clearance because of the tup expanded by heating.
" X " shape guide rail described in the utility model has the long arm of force, has strengthened the width of guide rail plate simultaneously, and the specific pressure that this will reduce to act on when hitting partially on the guide pass significantly helps prolonging service life of guide plate.Do not change owing to this tup guide rail can not be acted upon by temperature changes, it is very little that guide clearance can be transferred, so the forging precision of digital complete hydraulic die forging hammer is very high, and the forging stock utilization is very high, for " few nothing " cutting of forging is laid a good foundation.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, comprise tup 1, be arranged on the tup guide rail 2 of tup side, the tup guide rail is " X " shape guide rail structure.Described " X " shape guide rail structure is meant that the spigot surface of guide pass is the inclined-plane.And the spigot surface of tup guide rail is diagonal to be arranged, is the radial radiation shape when tup is heated and expands.Simultaneously, described " X " shape guide rail structure is meant specifically on the tup two sides and has gathering sill that the spigot surface before and after the gathering sill is the inclined-plane.This " X " shape guide rail structure is the radial radiation shape and expands when tup is heated.Just can not reduce the guiding clearance because of the tup expanded by heating.
