Abstract
Two-arm clamp is used in a kind of forging, relates to forging clamping device technical field; Usually, on the basis of original forging clamp, arrange the side of the connecting hole (3) of clamp top (1) to the first recessed arc clamping part (6), its one end arranges positioning and guiding top (10); The side of second connecting hole (4) of clamp bottom (2) is arranged the second arc clamping part (8) to fovea superior, its one end arranges positioning and guiding bottom (11).Positioning and guiding top (10) and positioning and guiding bottom (11) interior shape, wall thickness are determined according to forging outline shape and size respectively.Reduce the O&M of pattern making procedure in forging molding process, reduce the cost of forging molding processing.
Description
Technical field
The utility model relates to forging clamping device technical field.
Background technology
Usual forging clamp as shown in Figure 1, it is made up of the identical clamp top 1 of shape and clamp bottom 2, described clamp top 1 and clamp bottom 2 arrange the first connecting hole 3 and the second connecting hole 4 respectively, and fasten 5 by pin and be connected as a single entity in clamp top 1 and clamp bottom 2 through the first connecting hole 3 and the second connecting hole 4, and make clamp top 1 and clamp bottom 2 all can fasten 5 rotations around pin; The side of first connecting hole 3 on described clamp top 1 arranges the first arc clamping part 6 to fovea superior, and the opposite side of first connecting hole 3 on clamp top 1 arranges the first Handheld Division 7; The side of the second connecting hole 4 of described clamp bottom 2 arranges to the second recessed arc clamping part 8, and the opposite side of the second connecting hole 4 of clamp bottom 2 arranges the second Handheld Division 9.Described forging clamp mostly is a positioning and guiding top 10 and positioning and guiding bottom 11, and be welded on the segmental arc of the first arc clamping part 6 and the second arc clamping part 8, control opening and closed degree of positioning and guiding top 10 and positioning and guiding bottom 11 with the first Handheld Division 7 and the second Handheld Division 9, carry out the forging molding operations such as jumping-up, clamping, movement, reversion in order to the drum forging that crouches to difform two heads; When size is less than cavity impression size behind forging stock jumping-up one termination, during another termination of jumping-up, this clamp can be adopted, handle the first Handheld Division 7 and the Handheld Division 9 respectively by a people, forging molding processing is carried out to forging stock; But forging molding is carried out for less forging stock and adds man-hour, then inevitably can only carry out jumping-up, clamping, movement, reversion etc. by change type cavity mould size to forging stock to carry out forging molding and machined, this will increase the O&M of pattern making procedure virtually, thus the cost causing forging molding to be processed improves.
Utility model content
Technical problem to be solved in the utility model is: the O&M reducing pattern making procedure in forging molding process, reduces the cost of forging molding processing.
The technical solution of the utility model is:
Described forging two-arm clamp is made up of the identical clamp top 1 of shape and clamp bottom 2, described clamp top 1 and clamp bottom 2 arrange the first connecting hole 3 and the second connecting hole 4 respectively, and fasten 5 by pin and be connected as a single entity in clamp top 1 and clamp bottom 2 through the first connecting hole 3 and the second connecting hole 4, and make clamp top 1 and clamp bottom 2 all can fasten 5 rotations around pin; The side of first connecting hole 3 on described clamp top 1 arranges the first arc clamping part 6 to fovea superior, and the opposite side of first connecting hole 3 on clamp top 1 arranges the first Handheld Division 7; The side of the second connecting hole 4 of described clamp bottom 2 arranges to the second recessed arc clamping part 8, the opposite side of the second connecting hole 4 of clamp bottom 2 arranges the second Handheld Division 9, and one end that the side of first connecting hole 3 on clamp top 1 is arranged to the first arc clamping part 6 of fovea superior is arranged positioning and guiding top 10; One end that the side of the second connecting hole 4 of clamp bottom 2 is arranged to the second recessed arc clamping part 8 is arranged positioning and guiding bottom 11.Positioning and guiding top 10 and positioning and guiding bottom 11 interior shape, wall thickness are determined according to forging outline shape and size respectively.
In order to reduce the O&M of pattern making procedure in forging molding process, reduce the cost of forging molding processing, two-arm clamp is used in a kind of forging of special proposition, it is formed as shown in Figure 2, be on the basis of original forging clamp, one end that the side of first connecting hole 3 on clamp top 1 is arranged to the first arc clamping part 6 of fovea superior is arranged positioning and guiding top 10; One end that the side of the second connecting hole 4 of clamp bottom 2 is arranged to the second recessed arc clamping part 8 is arranged positioning and guiding bottom 11; Can realize that a people is hand-held first-handly to hold portion 7 and the Handheld Division 9, people and handle and carry out the forging molding processing such as jumping-up, clamping, movement, reversion to difform forging stock accordingly; Also can realize a people further to handle to sleeping drum two ends difformity and less forging stock carries out forging molding processing, thus avoid the O&M of many cover pattern making procedures as much as possible, reduce the cost of forging molding processing.
In order to meet the requirement of multiple sleeping drum forging nose shape, the working portion positioning and guiding top 10 of the first arc clamping part 6 and the second arc clamping part 8 and positioning and guiding bottom 11 can be made into the geomery needed for multiple head, as various shapes such as rectangle, square, circular, hexagons.
The beneficial effects of the utility model: the O&M decreasing pattern making procedure in forging molding process, reduce the cost of forging molding processing.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing forging clamp;
Fig. 2 is the structural representation of forging two-arm clamp of the present utility model.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail
The forging shape needed for part preparation of aircraft is that the stepped two ends of round platform crouches work shape Forging, need the blank forging of jumping-up two ends shaping, such blank pattern is difficult to by the operation needed for the forgings such as clamp jumping-up as shown in Figure 1, clamping, movement, upset two ends be shaping, blank carried out therefore has to come by dress pattern, thus increasing the forging cost of forging, and use two-arm clamp of the present utility model, as shown in Figure 2, positioning and guiding top 10 and the positioning and guiding top 11 that 8 weld the circular shape step head die cavity meeting the requirement of forging termination is respectively clamped at the first clamping part 6 and second of clamp top 1 and clamp bottom 2, adopt above-mentioned satisfactory positioning and guiding top 10 and positioning and guiding bottom 11, by a bit manipulation workman hand-held first Handheld Division 7 respectively, second Handheld Division 9 is handled, jumping-up is carried out to all types of forging that sleeping drum forging head and bar portion are ladder platform shape, clamping, mobile, upset waits the operation needed for forging, thus the special pattern of another termination of jumping-up needed for after no longer needing the special at one end head jumping-up of making, reduce the cost of forging molding processing.
