Detailed Description

The present invention will be described in further detail with reference to examples and embodiments.

As shown in figures 1-3, the novel bending angle structure capable of being adjusted quickly without removing the mold comprises an upper mold base 1, an upper padding plate 2, a fixed plate 3, a back stripping plate 4 and a stripper plate 5 which are arranged in sequence from top to bottom, and a lower mold base 8, a lower padding plate 7 and a cavity plate 6 which are arranged in sequence from bottom to top, and the structure comprises an adjusting rod fixing base 9, an adjusting rod 10, an adjusting part 11 and a bending part 13, wherein the adjusting rod fixing base 9 and the adjusting rod 10 are both in a 7 shape, the top surface of the horizontal part of the adjusting rod fixing base 9 is connected with the upper mold base 1, a first adjusting screw 17 is arranged on the vertical part of the adjusting rod fixing base 9 in a penetrating way, the end part of the first adjusting screw 17 contacts the outer side surface of the vertical part of the adjusting rod 10, a second adjusting screw 19 is arranged on the vertical part of the adjusting rod 9 in a penetrating way, the horizontal part, the adjusting parts 11 penetrate through the fixing plate 3 and the back stripping plate 4 and extend to the center of the discharging plate 5, a discharging plate insert 12 is arranged between the adjusting parts 11 on the two sides of the inner part of the discharging plate 5, the bottom ends of the adjusting parts 11 are in contact with the top of the bending part 13, a first return spring 15 is arranged at the center of the bending part 13, the middle part of the adjusting part 11 is connected with the fixing plate 3 through a second return spring 16, and a floating material block 14 is arranged at the center of the concave template 6.

The front end of the adjusting rod 10 is provided with an inclined plane near the adjusting part 11, the top end of the adjusting part 11 is matched with the inclined plane at the front end of the adjusting rod 10, the bottom end of the adjusting part 11 is provided with an inclined plane near the bending part 13, and the inclined plane at the bottom end of the adjusting part 11 is matched with the inclined plane at the top of the bending part 13.

According to the structure, when the angle of a product is too large and needs to be adjusted to reduce the angle, the second adjusting screw 19 at the lower part is firstly loosened, the first adjusting screw 17 at the upper part is adjusted inwards, the first adjusting screw 17 pushes the adjusting rod 10 to move forwards, the inclined plane at the front end of the adjusting rod 10 is propped against the inclined plane of the adjusting part 11, the adjusting part 11 moves downwards, the second return spring 16 is arranged in the adjusting part 11, and the adjusting part can automatically return when the angle is too large; when the adjusting part 11 continues to move downwards, the lower inclined surface contacts the inclined surface of the bending part 13, the bending part 13 rotates along the axis and is extruded to the outer side of the bending part of the product, and the bending part of the product is extruded by external force, so that the angle is reduced, and the purpose of adjusting the bending angle of the product is achieved.

When the angle of the product is adjusted too small, the first adjusting screw 17 on the upper surface is withdrawn in turn, the second adjusting screw 19 on the lower surface is locked, the second adjusting screw pulls the adjusting rod 10 to retreat, the adjusting part 11 pressed against the inclined surface of the adjusting rod 10 retreats under the action of the second return spring 16, and the bending part 13 pressed against the inclined surface of the adjusting part 11 rotates in the opposite direction under the action of the first return spring 15 to release the adjusting force pressed at the bending position of the product, so that the product is angularly expanded under the action of the resilience force, and the purpose of adjusting the excessively small bending angle is achieved.

When the bending angle of the product is adjusted, the die must be adjusted at the bottom dead center position of the punch press as shown in fig. 1, otherwise, the adjusting part is easily damaged.
