A Bending Machine Upper Die Fixture with Accurate Height Adjustment

Abstract

The invention discloses a bending machine upper die clamp allowing the height to be adjusted accurately. The clamp comprises a clamp locking mechanism and a bending compensation height adjusting mechanism. The clamp locking mechanism comprises a clamp plate fixing base, a front clamp plate, a rear clamp plate and the like, and the front clamp plate and the rear clamp plate are installed on the two sides of the clamp plate fixing base; the bending compensation height adjusting mechanism is located on the upper portion of the clamp plate fixing base and comprises a height adjusting plate, an eccentric shaft and a clamp fixing plate, the eccentric shaft penetrates through the clamp plate fixing base and the height adjusting plate to position the clamp plate fixing base and the height adjusting plate and then fixes the height adjusting plate to the clamp plate fixing base in a locking mode through screws, and the clamp fixing plate is fixed to the upper portion of the height adjusting plate through screws. When the height of the upper die clamp needs to be adjusted for bending compensation, the screws for locking the height adjusting plate are loosened, and the eccentric shaft is adjusted through rotation, so that the clamp plate fixing base deviates up and down relative to the clamp fixing plate to achieve height adjustment. According to the upper die clamp, the height of the clamp can be accurately adjusted according to scales, adjustment is more convenient, and moreover the front clamp plate and the rear clamp plate can be clamped or loosened through control of a hand shank, so that the bending machine upper die clamp is more flexible in use.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to an upper mold clamp for a bending machine. Background technique [0002] At present, the traditional bending machine upper die fixture widely used at home and abroad, such as figure 1 As shown, including splint fixing seat 1, front splint 2, rear splint 3, locking handle 4, etc., this upper mold fixture has the following two defects: 1) Only when the front splint is used in the two splints can it be quickly locked The handle locks the bending tool, and when using the rear splint, the bending tool needs to be locked with the rear splint locking screw, which is not flexible enough to use; 2) When bending compensation, it is necessary to adjust the upper mold by tapping the position of the scale slope 5 The height of the fixture is inconvenient to adjust and the adjustment degree is not easy to be accurate. Therefore, it is necessary to design a new type of upper die fixt...
