Description
Technical field
The utility model belongs to machine-building technical field of auxiliary equipment, is specifically related to a kind of structure and simply, for the large of large forgings opens width clamp.
Background technology
Forging is that one utilizes metal forming machinery to apply pressure to metal stock, it is made to produce plastic deformation to obtain the processing method with certain mechanical performance, definite shape and size forging, this processing method has built exquisite grain structure, and improves the physical attribute of metal.In hammered work, little forging can with manually forging, and heavy forging can only be forged by manipulator, existing many clamps for heavy forging, its amplitude of opening is restricted and required moment is larger, so the weight of the workpiece of clamping, shape and size are subject to stricter restriction, when clamping large-size massive forging, clamping forging can only be carried out to narrower size area, will carry out clamping to large-scale part, can only change larger clamp to carry out clamping, production efficiency is extremely low, not only waste the time, also indirectly add cost; Therefore, in order to improve the work accommodation size area of clamp, and improve the stability of clamp work, it is very important for researching and developing an a kind of large width clamp for large forgings.
Utility model content
The purpose of this utility model is to provide a kind of structure simply, for the large of large forgings to open width clamp.
The purpose of this utility model realizes like this, comprise tong arm, described tong arm is set to two relatively, in the middle part of described tong arm, fixed hub is set, described tong arm is mutually arranged in a crossed manner, and tong arm infall arranges fixed hub, tong arm is divided into clamping part and clamp handle by described fixed hub, described clamping part is oppositely arranged formation jaw, described jaw is divided into axle jaw peace wrench mouth, described dull and stereotyped jaw is arranged on the front inner opposite position of clamping part, and described axle jaw is arranged at the inner side opposite position of clamping part near fixed hub one section.
Clamp is set to two tong arm coaxial rotation by the utility model, is swung control jaw to the clamping of workpiece or unclamp by the opening and closing of clamp handle because can try one's best open jaw, so such design increases the work accommodation size range of heavy forging clamp.Jaw is divided into dull and stereotyped jaw and axle jaw, and the dull and stereotyped jaw of point contact type can carry out clamping to flat board flexibly, and plate can hold tighter by the dull and stereotyped jaw of face contact type, can optionally use according to actual needs; Axle jaw carries out clamping to axial workpiece, and the sawtooth of axle jaw design, when clamping shaft member, is clamped relatively by two flank of tooth of sawtooth, by shaft member clip in serrated slot, more firm, the subtended angle of sawtooth is set to 90 ° ~ 145 °, makes axle jaw can adapt to the shaft member clamping of various diameter dimension; The length of clamp handle is greater than 2/3 of the length of clamping part, flexibly more convenient during control clamp handle.

Fig. 3 is another embodiment of the present utility model;
Fig. 4 is duty of the present utility model;
In figure: 1-clamping part, 2-fixed hub, 3-clamp handle, 4-power axle sleeve, 5-axle jaw, the dull and stereotyped jaw of 6-, 7-forging.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, but must not be limited the utility model by any way, any change done based on the utility model training centre or improvement, all belong to protection domain of the present utility model.
As shown in accompanying drawing 1 ~ 4, the utility model comprises tong arm, described tong arm is set to two relatively, fixed hub 2 is set in the middle part of described tong arm, described tong arm is mutually arranged in a crossed manner, and tong arm infall arranges fixed hub 2, tong arm is divided into clamping part 1 and clamp handle 3 by described fixed hub 2, described clamping part 1 is oppositely arranged formation jaw, described jaw is divided into the peaceful wrench mouth 6 of axle jaw 5, described dull and stereotyped jaw 6 is arranged on the front inner opposite position of clamping part 1, and described axle jaw 5 is arranged at the inner side opposite position of clamping part 1 near fixed hub 2 one sections.
The front end of described clamping part 1 is set to arc transition.
As shown in Figure 1, arrange angled transition section between the peaceful wrench mouth 6 of described axle jaw 5, described dull and stereotyped jaw 6 is point contact type jaw.
As shown in Figure 2, described dull and stereotyped jaw 6 is set to the dull and stereotyped jaw of face contact type, and described dull and stereotyped jaw 6 is directly connected with between axle jaw 5, without angled transition section.
As shown in Figure 3, dull and stereotyped jaw 6 part of described clamping part 1 is set to zigzag.
As shown in Figure 3, axle jaw 5 part of described clamping part 1 is set to zigzag, and the subtended angle of sawtooth is 90 ° ~ 145 °.
Described clamp handle 3 part is set to straight-bar or bent stick laterally, and the rearward end of clamp handle arranges power axle sleeve 4.
The length of described clamp handle 3 is greater than 2/3 of the length of clamping part 1.
operation principle of the present utility model and the course of work
Clamp is set to two tong arm coaxial rotation by the utility model, is swung control jaw to the clamping of workpiece or unclamp by the opening and closing of clamp handle 3 because can try one's best open jaw, so such design increases the work accommodation size range of heavy forging clamp.Jaw is divided into dull and stereotyped jaw 6 and axle jaw 5, and the dull and stereotyped jaw of point contact type can carry out clamping to flat board flexibly, and plate can hold tighter by the dull and stereotyped jaw of face contact type, can optionally use according to actual needs; Axle jaw 5 pairs of axial workpieces carry out clamping, and the sawtooth of axle jaw design, when clamping shaft member, is clamped relatively by two flank of tooth of sawtooth, by shaft member clip in serrated slot, more firm, the subtended angle of sawtooth is set to 90 ° ~ 145 °, makes axle jaw can adapt to the shaft member clamping of various diameter dimension; The length of clamp handle is greater than 2/3 of the length of clamping part, flexibly more convenient during control clamp handle.
During work, fixed hub is arranged on dead axle, by controlling power axle sleeve, carries out force production to line shaft cover, controls opening and closing and the aperture size of jaw, carries out clamping to forging.
