Problems solved by technology
However, the double-slider forming technology creates a negative angle through lateral bending, and needs to leave space for the manipulator to feed the material, so the space requirement for the mold is very large, resulting in an increase in the cost of the mold

The invention relates to a material lifting, rotating and negative angle forming mechanism capable of reducing die space and reducing the die cost. The mechanism comprises a male die on an upper die holder and a female die on a lower die holder, the edge of the top face of the female die protrudes, and the male die is used for punching the female die under the driving of the upper die holder. A lower clamping block which is inclined close to the female die is arranged on the side adjacent to the female die, the lower clamping block is connected with a rotary structure to drive the lower clamping block to rotate from an inclined state to a vertical state, the lower clamping block has a horizontal plane on the top face in the inclined state to place a to-be-punched blank, and the lower clamping block is connected with a first shifting structure to realize vertical displacement. An upper clamping block is arranged on the side adjacent to the male die, the upper clamping block is connectedwith a second shifting structure to move up and down, the bottom of the upper clamping block is provided with an inclined surface which is inclined close to the male die, and when the lower clampingblock is rotated to the vertical state, the inclined surface is parallel to the rotated horizontal plane so as to clamp the blank between the inclined surface and the horizontal plane.
Description
technical field [0001] The invention relates to the field of metal stamping manufacturing, in particular to a material lifting rotating negative angle forming mechanism. Background technique [0002] In the mold manufacturing industry, mold cost control is the top priority of mold design. Therefore, in the past, double-slider forming technology was used to meet the needs of both negative-angle bending and manipulator feeding avoidance in one out of two molds. However, the double-slider forming technology creates a negative angle through lateral bending, and needs to leave space for the manipulator to feed and escape, so the space requirement for the mold is very large, resulting in an increase in the cost of the mold. Contents of the invention [0003] In order to improve the deficiencies in the prior art, the present invention provides a material lifting and rotating negative angle forming mechanism, which can reduce the mold space and reduce the mold material cost.
