Abstract
The utility model discloses a non-trunnion clamping head for forging pressure heating, which comprises the outer shell of the clamping head, a movable clamping jaw, a pushing block and a pull rod, wherein, the movable clamping jaw, the pushing block and the pull rod are arranged in the outer shell of the clamping head. The movable clamping jaw is an intermediate section with a cylindrical surface, and the cylindrical surface is arranged on a lever body which is arranged between the concave cylindrical surface of the outer shell of the clamping head and the concave cylindrical surface of the upper part of the pushing block. The utility model has the advantages of simple structure, high safety, high rigidity, wear resistance and burning resistance.
Description
The utility model relates to the chuck that the charging and discharging machine tool uses on hand in a kind of forging industry, is the no hinge chuck of a kind of forging and pressing heating specifically.
At present, the charging and discharging machine tool hand chuck that uses generally adopts jaw to rotate this structural principle around bearing pin both at home and abroad, and this chuck structure is huge, is difficult to long-term work in high temperature furnace, not anti-burning, not wear-resisting.
The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned prior art, and provides a kind of rigidity big, anti-burning, wear-resisting, and also forging and pressing simple in structure heating is with no hinge chuck.
The utility model is to adopt following measure to realize its purpose.
Be mounted with active chuck, jacking block and pull bar in the chuck shell, active chuck is that a stage casing has a face of cylinder and this face of cylinder and inserts lever body between the recessed cylinder on the recessed cylinder of chuck shell inboard and jacking block top.One end of movable jaw is inserted between a voussoir and the guide pad, and voussoir is connected with pull bar, and guide pad is synchronized with the movement with voussoir.The face of cylinder width of active chuck equals the jacking block width, and seals the openend of chuck shell jointly.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model list folder formula structural representation;
Fig. 2 is the utility model double-jaw type structural representation;
Fig. 3 is the structural representation of conventional clip.
Below in conjunction with accompanying drawing the utility model is further described.
The utility model is closed no hinge chuck, is divided into two kinds of single jaw motion and the motions of double fastener pawl.Because of its structural principle of each jaw in the double fastener pawl is identical with movable jaw structural principle in single jaw, so be that example is described with single jaw.Movable jaw (1) is a lever body, its stage casing has a face of cylinder (2) (3), another jaw (7) of single jaw is a stationary jaw, in chuck shell (5) inboard a recessed cylinder (3) is arranged, the corresponding jacking block (8) of settling a top to have recessed cylinder (2) under this recessed cylinder (3), two recessed cylinders (2), (3) face of cylinder (2) in movable jaw (1) stage casing in clamping, (3), be movable jaw (1) be subjected to the motive force of voussoir (9) can be around the face of cylinder center line of (recessed cylinder) rotate, thereby make jaw (1) press to weight, realize clamping action.Chuck is an enclosed construction, does not expose the bearing pin parts, therefore can stop the long period in high temperature furnace, simultaneously, the face of cylinder (2), (3) and chuck shell (5) length of action maximum, wear extent is less, and promptly being has wearing and tearing then only to need the suitable bed hedgehopping of jacking block (8) is got final product.The synchronization-moving guide pad of voussoir (9) (4) is followed at movable jaw (1) back, the backlass of its restriction jaw (1) afterbody, thus make jaw (1) front end that bigger rigidity be arranged, so that jaw is oppositely stirred blank or is clashed into.Blank passes to pull bar (6) to the reverse torsion of jaw (1) by voussoir (9), but because it to the normal pressure of voussoir (9) angle of friction no better than, so it is a lot of promptly to be that the pulling force of pull bar (6) reduces, can not cause the blank obscission yet.
The utility model is simple in structure, and is safe and reliable, owing to adopted closed no pin shaft structure, so it is big to have rigidity, and anti-burning, wear-resisting characteristics, this chuck clamping weight weight can reach 5000 kilograms.
Claims (3)
1, the no hinge chuck of a kind of forging and pressing heating, it is made up of chuck shell and movable jaw, jacking block and the pull bar of inserting in the chuck shell, it is characterized in that movable jaw is that a stage casing has the lever body between the recessed cylinder that a face of cylinder and this face of cylinder place the recessed cylinder of chuck shell inboard and jacking block top.
2, forging and pressing heating according to claim 1 is characterized in that with no hinge chuck an end of described movable jaw is inserted between a voussoir and the guide pad, and voussoir is connected with pull bar, and guide pad is synchronized with the movement with voussoir.
3, forging and pressing heating according to claim 2 is characterized in that the face of cylinder width of active chuck equals the jacking block width, and seals the openend of chuck shell jointly with no hinge chuck.
