Detailed Description
Referring to fig. 1-2, the present invention will be further described with reference to the following embodiments.
The utility model relates to a precision parts machining field, especially a mould of bending, its characterized in that: the die-stripping mechanism is provided with a base 1, a first positioning hole 4 is formed in the center of a circle of the base 1, an elastic part 8 is arranged in the first positioning hole 4, the top of the elastic part 8 is connected with a die-stripping ejector rod 7, an end cover 2 is further arranged on the upper portion of the base 1, a second positioning hole 6 is formed in the center of the circle of the end cover 2, the die-stripping ejector rod 7 extends out of the second positioning hole 6, a pair of positioning clamps 6 are further arranged on the top of the end cover 2, and a forming pressing rod 3 is matched with the positioning clamps 6.
When the device works, the top of the forming compression bar 3 is connected with the execution end of a machine tool, a plate to be processed is placed on the two positioning clamps 6, the execution end of the machine tool drives the forming compression bar 3 to move downwards to extrude the plate, no movement space exists at the two ends of the plate due to a gap between the two positioning clamps 6, the middle part of the plate moves downwards under the extrusion of the forming compression bar 3 to deform, and the middle part of the plate and the lower part of the forming compression bar 3 in a trapezoidal structure are gradually attached to form an L shape and form two right angles; at the moment, the execution end of the machine tool drives the forming pressure rod 3 to move upwards, the processed plate is pushed by the die stripping ejector rod 7 to complete die stripping, and thus the plate to be processed can form two right angles through one-time extrusion.
The further technical scheme can be that the two positioning clamps 6 are symmetrically arranged at two sides of the central axis of the end cover 2, and the included angle between the bottom surfaces of the two positioning clamps 6 and the top surface of the end cover 2 is 4-8 degrees.
The included angle between the bottom surface of each positioning clamp 6 and the top surface of the end cover 2 is 4-8 degrees, the space formed between the two positioning clamps 6 is in an inverted trapezoid shape and is matched with the forming pressing rod 3, and the plate enters the space under extrusion to form two right-angle folding angles.
And the lower section of the molding press rod 3 is trapezoidal, the rod body of the molding press rod 3 is also provided with two limiting steps 3.1, and the two limiting steps 3.1 are respectively positioned at two sides of the rod body.
The two limiting steps 3.1 limit the longitudinal strokes of the two ends of the plate when the plate is extruded, so that the plate is prevented from being excessively bent, and the machining precision is high.
The further technical scheme is that the elastic part 8 can be a spring.
The spring gives an upward force to the die-stripping ejector rod 7, and the die-stripping ejector rod 7 ejects the plate upwards under the extrusion of the elastic part 8 after the plate is processed, so that the die stripping is completed.
And the bottom of the molding press rod 3 is arranged between the two positioning clamps 6.
The forming press rod 3 is matched with the two positioning clamps 6 to complete the bending of the plate.
