Abstract
The utility model relates to a clamping device for a precision forging process production line of steel rail turnouts. The clamping device comprises a rack body and is characterized in that a hydraulic oil cylinder is fixedly arranged on the rack body; the head part of the hydraulic oil cylinder is connected with a push block; two oblique blocks are respectively connected with the upper end of the push block, close to the two sides of the push block; the inner side faces of the two oblique blocks are matched and connected with sliding blocks of jaws arranged on the two oblique blocks in a sliding manner; the sliding blocks are matched and connected with the rack body in a sliding manner; and removable tong blocks are arranged at the jaw positions of the sliding blocks. The clamping device has the advantages that as the hydraulic oil cylinder drives an oblique surface force-amplifying mechanism to clamp steel rails, the clamping force is large, the self-locking performance is good, and the steel rails can be clamped reliably; and as the steel rails are fed, rotated and the like, tongs do not get loosened, and the subsequent feeding precision is ensured. The oblique blocks push the sliding blocks to perform clamping by adopting copper guide plates for guiding, wherein the copper guide plates have good sliding and guide properties and can be replaced after abrasion. The tong blocks after special processing are not crushed or abraded as the larger clamping force is imposed upon the tong blocks; and after being used for a long time, the tong blocks are easy to replace.
Description
Technical field
The utility model belongs to the hydraulic press technical field, particularly relates to a kind of rail track switch forging production line clamp clamping device.
Background technology
In recent years, increasing to the demand of track along with railway transportation develops to high-speed overload, the quality of requirement is increasingly high, requires the efficient of production also more and more faster.The rail forging equipment is one of the equipment of the processing rail of Rail Production enterprise, and it can realize the technological requirement to product hot-die compression mouldings such as various tongues, wing rail and various heart rails by means of various moulds.Because the length dimension of rail is bigger; It is that it carries rail that the rail forging equipment needs pay-off; And forging equipment is repeatedly accurately forging and pressing such as rail head, the web of the rail, the flange of rail to rail, therefore the level of rail, vertical, upset is carried and has been proposed higher required precision and efficient requirement.Clamp clamping device of the prior art adopts the lever construction of hydraulic oil cylinder driving to clamp rail; Owing to receive spatial constraints to cause its chucking power less, when rail is done flip-flop movement, loosening phenomenon can occur; Influence follow-up feeding action and precision; And jaw and lever design are an overall structure, and be more easy to wear, after damage, changes more loaded down with trivial details.
Summary of the invention
The utility model is stablized for the technical problem that exists in the solution known technology provides a kind of, the reliable grip rail; Can avoid occurring loosening phenomenon when rail is done flip-flop movement, guarantee the rail track switch forging production line clamp clamping device of follow-up pushing precision.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Rail track switch forging production line clamp clamping device; Comprise support body, it is characterized in that: be fixed with hydraulic jack on the said support body, said hydraulic jack head connects pushing block; Said pushing block upper end connects skewback respectively near both sides; Said two skewback medial surfaces and be shaped on the sliding shoe sliding connection of jaw on it, said sliding shoe and support body sliding connection are equipped with removable pincers piece in the sliding shoe jaw position.
The utility model can also adopt following technical scheme:
Sliding surface between said sliding shoe and the support body is equipped with guide plate.
Said guide plate is the copper guide plate.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, when promptly hydraulic jack drove inclined-plane force-increasing mechanism clamping rail, clamping force was big, and self-locking performance is good, can the reliable grip rail.Send in that rail is done, when rotation waited action, clamp can not become flexible, and guarantees follow-up pushing precision; Skewback through copper guide plate guiding, slides, guidance quality is good in promoting the sliding shoe clamping process, and the wearing and tearing back is replaceable.Through the pincers piece of specially treated unlikely conquassation and the wear phenomenon of occurring during at larger clamping force, after long-time the use, also can change easily.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, support body; 2, hydraulic jack; 3, pushing block; 4, skewback; 5, sliding shoe; 6, guide plate; 7, pincers piece.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, rail track switch forging production line clamp clamping device comprises support body 1, is fixed with on the said support body 1 to be used to drive the hydraulic jack 2 that pushing block moves up and down.Said hydraulic jack head connects the pushing block 3 that is shaped on boss on it, and said pushing block 3 upper end boss connect skewback 4 respectively near both sides.Said two skewbacks, 4 medial surfaces and be shaped on sliding shoe 5 sliding connections of jaw on it, said sliding shoe 5 and support body 1 sliding connection are equipped with removable pincers piece 7 in the sliding shoe jaw position.Sliding surface between said sliding shoe and the support body is equipped with guide plate 6, and in the present embodiment, said guide plate 6 is the copper guide plate.
Said skewback 4 and sliding shoe 5 are with sliding connection, and when hydraulic jack promoted the pushing block motion, pushing block promoted skewback, and skewback promotes sliding shoe along bevel direction and moves, and the reinforcement effect owing to the inclined-plane makes sliding shoe can clamp rail.
Said sliding shoe and support body 1 be with sliding connection, and after the sliding shoe both sides were promoted by skewback, sliding along the support body spigot surface clamped rail.
Sliding surface between said skewback, sliding shoe and the support body all has the copper guide plate as guiding, and the sliding of copper guide plate and guidance quality are all better, helps skewback, sliding shoe slides on support body, and copper guide plate wearing and tearing back is replaceable.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
