Description

Two-arm clamp is used in one kind forging

Technical field

The utility model is related to forging clamping device technical field, and two-arm clamp is used in specially a kind of forging.

Background technology

Forging is divided into open die forging and die forging, and general large cylindrical forging is that can obtain by die forging, the process of die forging be by The blank of heating is put into mould, then beats blank repeatedly by die hammer, by the shape of blank forge and press to mold shape It is identical, clamp is often used during forging, but, traditional forging is heavier with the volume of two-arm clamp, inconvenience In carrying, the heat-proof quality of clamp handle is poor, and worker is easily burned in the forge piece of clamping overheat, and unstable during clamping It is fixed, can also slide sometimes, danger is caused, in addition, when worker clamps forge piece with clamp, needing laterally to exert oneself for a long time Clamping forge piece, such operating type considerably increases the labour intensity of worker, and, worker worked long hours Afterwards, muscle power can not be propped up, and cause clamping dynamics not enough to occur the situation that forge piece comes off.

Utility model content

The purpose of this utility model is to provide a kind of forging two-arm clamp, to solve what is proposed in above-mentioned background technology Problem.

To achieve the above object, the utility model provides following technical scheme：Two-arm clamp, including left pincers are used in one kind forging Handle and right clamp handle, the left clamp handle and right clamp handle are by together with hinge, and one end of left clamp handle and right clamp handle is welded respectively It is connected to left nipper and right nipper, the other end of left clamp handle and right clamp handle is set with collet, and dead lock is provided with left clamp handle, Alignment pin is installed on right clamp handle and dead lock correspondence position, the dead lock is provided with the location hole of equidistantly distributed, described Anti-skidding groove is equipped with the inwall of left nipper and right nipper.

Preferably, the left nipper is identical with the shape and structure of right nipper, and left nipper and right nipper axisymmetricly set Put.

Preferably, the dead lock is to be connected by fastening bolt between arcuate structure, and dead lock and left nipper.

Preferably, the junction of the left clamp handle and right clamp handle is provided with pin shaft hole, and the bearing pin is arranged in pin shaft hole.

Preferably, the location hole is circular port, and the inwall of location hole is provided with antiskid thread.

Compared with prior art, the beneficial effects of the utility model are：The utility model, simple structure, volume is light and handy, takes Band is convenient, by the anti-skidding groove being provided with left nipper and right nipper inwall, can increase the rubbing surface of nipper and forge piece Product, plays anti-skidding effect, by the dead lock being provided with left clamp handle, when forge piece is clamped with the clamp, and can be with profit Left clamp handle and right clamp handle are securely seated between together with dead lock, so that forge piece is firmly jammed, change biography The clamp of system needs worker's operating type for a long time laterally firmly, it is to avoid it is inadequate that worker clamps dynamics after working for a long time And cause the situation that forge piece comes off from clamp to occur, it is time saving and energy saving, significantly reduce the labour intensity of worker, by The collet that left clamp handle and right clamp handle one end are set with, with good heat-proof quality, it is to avoid the forging of worker's clamping overheat Situation about being scalded during forging piece occurs, and improves the security for using.

Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Refer to Fig. 1-3, a kind of embodiment that the utility model is provided：Two-arm clamp, including left clamp handle 1 are used in one kind forging With right clamp handle 2, left clamp handle 1 and right clamp handle 2 be hinged by bearing pin 4, and one end of left clamp handle 1 and right clamp handle 2 is welded respectively It is connected to left nipper 6 and right nipper 5, the other end of left clamp handle 1 and right clamp handle 2 is set with collet 3, with good thermal insulation Can, it is to avoid situation about being scalded during the forge piece of worker's clamping overheat occurs, and improves the security for using, in left clamp handle 1 Dead lock 7 is installed, when forge piece is clamped with the clamp, it is possible to use dead lock is firmly solid by left clamp handle 1 and right clamp handle 2 It is scheduled on together, so that forge piece is firmly jammed, changing traditional clamp needs what worker laterally exerted oneself for a long time Operating type, it is to avoid worker clamps dynamics after working for a long time not enough cause the situation that forge piece comes off from clamp to be sent out It is raw, it is time saving and energy saving, the labour intensity of worker is significantly reduced, alignment pin is installed on right clamp handle 2 and the correspondence position of dead lock 7 10, dead lock 7 is provided with the location hole 11 of equidistantly distributed, and anti-skidding groove is equipped with the inwall of left nipper 6 and right nipper 5 12, the friction area of nipper and forge piece can be increased, play anti-skidding effect, the shape and structure of left nipper 6 and right nipper 5 It is identical, and left nipper 6 and right nipper 5 axisymmetricly set, dead lock 7 is between arcuate structure, and dead lock 7 and left nipper 6 Connected by fastening bolt 9, the junction of left clamp handle 1 and right clamp handle 2 is provided with pin shaft hole 8, and bearing pin 4 is arranged in pin shaft hole 8, fixed Position hole 11 is circular port, and the inwall of location hole 11 is provided with antiskid thread.

Specifically used mode：The utility model, when using, is clamped forge piece using left nipper 6 and right nipper 5, left Anti-skidding groove 12 on nipper 6 and right nipper 5 can increase the friction area with forge piece, play anti-skidding effect, meanwhile, when When clamping forge piece, the location hole 11 on dead lock 7 is plugged on alignment pin 10, so that left clamp handle 1 and right clamp handle 2 are firmly Be fixed together so that forge piece is firmly clamped, changing traditional clamp needs staff for a long time laterally Operating type firmly, significantly reduces the labour intensity of worker.
