Abstract

The utility model discloses a gripping apparatus for metal blank and is utilized to grip and transport metal blank material. The utility model comprises four connecting rods hinged together by five connecting shafts and grouped by two. The upper part of the utility model is welded with a ring, and the connecting rods at the lower part are welded with claws utilized as gripping apparatuses of metal blank; the middle of the utility model is provided with an automatic and tripping mechanism consisting of a guide bar, a locking sleeve, a tripping sleeve and a locking hook. The utility model has reliable automatic loading and unloading function.

Description

Gripping apparatus for metal blank

Technical field the utility model relates to a kind of Gripping apparatus for metal blank that is applied to be used in the metallurgy industry grasping the bigger cold and hot metal stock of quality.

Background technology national patent ZL94216978.6 discloses a kind of " Ingot clincher ", this gripping apparatus realizes that by the breach of the throw-out lever on the gripping apparatus and the screens of fixed link gripping apparatus opens, action by locking block resets again then, can realize cutting lotus without the manual operation automatic loading and unloading.Because the high temperature and the heavy load of metallurgical production, usage condition is poor, and the throw-out lever of this patent, fixed link, locking block because wearing and tearing and collision make the gap between each component become big, are difficult to realize automatic loading and unloading after long-time the use.

The summary of the invention the purpose of this utility model is to provide a kind of service-strong Gripping apparatus for metal blank, to realize the automatic loading and unloading to cold and hot metal stock in the smelter.

For realizing the purpose of this utility model, the technical scheme that is adopted is: this gripping apparatus is by five hinged forming of adapter shaft by two groups of four connecting rods, one face down bonding of the adapter shaft of topmost is connected to suspension ring, two connecting rods of bottom are welded with the gripper of gripping metal base, the gripper lower inside has barb, bottom two connecting rods are hinged by connecting panel, attaching has crossbeam between two connecting panels, guide rod is arranged in the middle of the crossbeam, the dropout cover of the combination bodily form that two Rotary-table bottom surfaces overlap and the locking cover that empty cone cylinder body shape is processed in the bottom are housed on the guide rod, corresponding mutually also energy tight connecting in the bottom of the last conical surface that dropout is overlapped and locking cover and outside dimensions are the same, the locking cover is fixed on the guide rod by bearing pin, the cover of threading off can move along the guide rod easy on and off, guide rod passes the adapter shaft of topmost and can move freely in its hole, the lock hook of the corresponding opposite side of the adapter shaft of topmost and suspension ring by hinged two the lower end buckles of bearing pin, the distance of two lock hook inboards are not more than the diameter that outer is overlapped in locking.

Adopting as above technology is the Gripping apparatus for metal blank that scheme is made, because the locking cover and the cover of threading off be installed on the guide rod at gripping apparatus center, move more reliably, and period of service is long also can be because of wearing and tearing or collision etc. cause the problem that cooperation is bad, can improve gripping apparatus service life.

Description of drawings Fig. 1 is the front elevational schematic of a kind of Gripping apparatus for metal blank described in the utility model, also is specification digest accompanying drawing of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to scheme drawing.

The specific embodiment is described in further detail the specific embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2,1 is suspension ring, and 2 is connecting rod, and 3 are the locking cover, and 4 is guide rod, and 5 are the cover of threading off, and 6 is connecting panel, and 7 is adapter shaft, and 8 is lock hook, and 9 is crossbeam.

This gripping apparatus is formed with nut is hinged by five adapter shafts by two groups of four connecting rods 2.When needs grasp metal base, gripping apparatus is because the action of gravity of self, open the gripping apparatus bottom, the top that lock hook 8 is moved down into the cover 5 of threading off moves to the bottom of the cover 5 of threading off along its inclined-plane, lower link 2 is in the gripping state for the treatment of simultaneously, when external force acts on when moving up on the suspension ring 1, the adapter shaft 7 of topmost moves up and drives lock hook 8 simultaneously and move up, lock hook 8 drives the cover 5 of threading off along upwards operation of guide rod 4, connecting rod 2 shrinks the gripping metal base to the center simultaneously, when driving, lock hook 8 moves on the cover 5 of threading off when locking cover 3 and contact, the cover 5 of threading off moves on no longer, and 8 continuation of lock hook move up along the lower inclined plane of the cover 5 of threading off, because the cover 5 of threading off is the same with corresponding mutually also energy tight connecting in the bottom of locking cover 3 and outside dimensions, lock hook 8 can not hang over the bottom of locking cover 3 and move on continuing, and can grab the metal base of slinging.

When needs put down metal base, gripping apparatus was to transferring, and lock hook 8 is moved down into the bottom of locking cover 3, at this moment gripping apparatus will cut lotus and unclamp and put down, and gripping apparatus is sling, and lock hook 8 just tangles the bottom of locking cover 3, gripping apparatus will keep open state to leave suspended object, reaches the purpose of automatic loading and unloading.
