Detailed Description

The utility model will now be described in further detail with reference to the drawings and the specific embodiments, without limiting the scope of the utility model.

As shown in fig. 1, an aluminum alloy forging piece flaring clamp of the present embodiment includes a left clamping rod 1 and a right clamping rod 2 which are hinged together in a scissor shape through a pin 3, wherein a clamping end of the left clamping rod 1 is bent to a left lower side to form a left clamping portion 11, a clamping end of the right clamping rod 2 is bent to a right lower side to form a right clamping portion 21, and the left clamping portion 11 is positioned at a left side of the right clamping portion 21; the clamping plates 4 with enlarged clamping surfaces are arranged on the outer sides of the left clamping part 11 and the right clamping part 21.

The transporting and clamping of the forging with the inner hole is specially used for the transporting and clamping of the forging with the inner hole, particularly, materials are softer, for example, the transporting and clamping of the aluminum alloy forging during die forging is performed, the clamp of the embodiment is illustrated by a handheld clamp, and in actual production, a driving mechanism can be arranged at the holding end of the clamp, so that automatic or semi-automatic operation is realized, and the labor intensity of workers is reduced.

The length of the holding end of the handheld clamp is far longer than that of the holding end, so that labor is saved, a worker can conveniently operate the handheld clamp by hands, two clamping rods of the holding end of the clamp are bent downwards towards each other again, the left clamping part 11 is positioned on the left side of the right clamping part 21, and therefore when the holding end of the clamp is pinched, the holding end of the clamp is outwards opened, namely, the left clamping part 11 and the right clamping part 21 move away from each other. The bent clamp clamping end is convenient to insert into a hole of the aluminum alloy forging, and the clamp plate 4 which is abutted against the surface of the aluminum alloy forging can reduce the pressure intensity of an abutting point, so that the forging is prevented from being damaged.

The angle of the downward bending of the clamping end of the left clamping rod 1 and the clamping end of the right clamping rod 2 is 60 ° -90 °, in this embodiment, 90 ° is adopted, the distance from the left clamping part 11 formed after bending to the pin shaft 3 is smaller than that of the right clamping part 21, and in order to make the force balance symmetrical with the forging contact part, the welding points of the clamping plate 4 at the left clamping part 11 or the right clamping part 21 are properly adjusted, so that the distances from the clamping plate 4 arranged at the left clamping part 11 and the clamping plate 4 arranged at the right clamping part 21 to the pin shaft 3 in the X, Y, Z direction are respectively equal.

The inner hole of the aluminum alloy forging piece is a round hole, and the clamping plate 4 is an arc plate protruding outwards; in actual production, the clamping plate 4 can be provided with other shapes, such as a flat plate, according to the shape of the inner hole of the clamped forging. In addition, in order to prevent the flat plate 4 from being inserted into the inner hole of the forging piece too deeply and abutting against the die, the height of the clamping plate 4 is not greater than the thickness of the inner hole part of the aluminum alloy forging piece, and a limit flange is arranged on the outer side of the top end of the clamping plate 4.

Finally, it should be noted that the foregoing embodiments are merely for illustrating the technical solution of the present utility model, and the front, rear, left, right, upper, middle, lower, etc. directions adopted for the description of the technical solution are set based on the drawings, not limiting the scope of the present utility model, although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made to the technical solution of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
