Abstract
The utility model provides a kind of self-locking forging operation to clamp, and it comprises two claw beams, activity clencher, self-locking devices; Claw beam one end is operating grip, and the other end is bare terminal end; Two claw beams are articulated and connected by activity clencher, and self-locking device correspondence is located at the handle section of two claw beams.Its effect is: the labour intensity 1, reducing operating personnel; 2, simple to operation and can increase work efficiency.
Description
Technical field: the utility model relate to a kind of improvement for the handling tongs in Forging Operation, particularly a kind of self-locking forging operation pincers.
Background technology: at machine industry, the handling tongs that operating personnel manages in forging process uses the handling tongs of simple and easy version mostly, it fixedly consists of an activity clencher intersection two claw beams, and claw beam one end is operating grip, and the other end is bare terminal end; The deficiency that the handling tongs of this kind of structure in use exists is: labour intensity is large, operating personnel are easily tired, because after forging clamps by operating personnel, rely on both hands firmly to clamp with strength and just can guarantee that forging is unlikely to fall down, in this case, operating personnel is easy to fatigue, if the clamping required time continued is long, then operating personnel is all the more so, thus affect manufacturing schedule, reduce working efficiency.
Summary of the invention: the purpose of this utility model is, the labour intensity in use existed for the handling tongs of simple and easy version in existing forging process is large, operating personnel holds fatigable deficiency, and a kind of self-locking forging operation pincers are proposed, it has self-locking device, it completes self-locking while clamping forge piece, operating personnel can be made without the need to re-using chucking power, thus reduce the labour intensity of operating personnel.
Can realize the purpose of this utility model by following technical proposals, a kind of self-locking forging operation pincers, is characterized in that, comprise two claw beams, activity clencher, self-locking devices; Claw beam one end is operating grip, and the other end is bare terminal end; Two claw beams are articulated and connected by activity clencher, and self-locking device correspondence is located at the handle section of two claw beams.
Self-locking device is made up of tapered end and snap close; Snap close is made up of locking-bar, cramp, spring, and the front end of locking-bar is grooved, and the middle part of cramp is fixed on notch end, and both ends of the spring is separately fixed on locking-bar and cramp.
For ease of the relative position between adjustment tapered end and snap close, the link of tapered end and snap close and claw beam is the sliding sleeve that a locking is arranged.
For preventing forging from sliding when clamping, the clamping face of claw beam bare terminal end is set to crocodile dentation.
Effect of the present utility model is: the labour intensity 1, reducing operating personnel, because this handling tongs completes self-locking while clamping forge piece, so, go with strength again to continue clamping forge piece without the need to operating personnel after clamping forge piece, thus reduce the labour intensity of operating personnel; 2, simple to operation and can increase work efficiency, this device automatically locks when clamping forge piece, when unclamping forging, only need pinch cramp with hand; Because this device can reduce the labour intensity of operating personnel, thus can reduce the fatigue strength of operating personnel, the state of mind is good at work to make operating personnel.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the enlarged diagram of dotted line frame A place structure in accompanying drawing 1.
Below in conjunction with drawings and Examples, the utility model is further elaborated:
Detailed description of the invention:
See accompanying drawing 1,2, a kind of self-locking forging operation pincers, it is primarily of two claw beams 1, activity clencher 2, self-locking device composition; Claw beam 1 one end is operating grip, and the other end is bare terminal end; Self-locking device is made up of tapered end 3 and snap close; Snap close is made up of locking-bar 4, cramp 5, spring 6, and the front end of locking-bar 4 is grooved, and the middle part of cramp 5 is fixed on notch end, and spring 6 two ends are separately fixed on locking-bar 4 and cramp 5.Two claw beams 1 are articulated and connected by activity clencher 2; Tapered end 3 and snap close correspondence are located at the handle section of two claw beams 1 respectively.For ease of the relative position between adjustment tapered end 3 and snap close, the link of tapered end 3 and snap close and claw beam is one be provided with the sliding sleeve 7 locking and arrange, and sliding sleeve 7 is enclosed within claw beam 1.For preventing forging from sliding when clamping, the clamping face of claw beam 1 bare terminal end is set to crocodile dentation.
Work flow is: forging clamps with hold with a firm grip the respectively handle end of claw beam 1 of two hands by operating personnel, meanwhile, self-locking device self-locking, crocodile tooth is by forging firm grip; After forging, pinch cramp 5 with hand, spring-compressed 6, snap close is opened, and tapered end 3 is transferred to, and forging unclamps from handling tongs, completes an operating process.When adjusting the relative position between tapered end 3 and snap close, the locking only need unclamped in sliding sleeve 7 arranges and sliding sleeve 7 is slided into desired location along claw beam 1 and locks sliding sleeve 7 again.
