Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 3, a punching and flanging conversion die device comprises a clamping die for clamping a pipe; the clamping die is clamped through a clamping device; a conversion die 123 for switching punching and flanging processes is arranged in the clamping die; the apparatus further comprises switching means 120; the switching device 120 is used for driving the conversion die 123 to reciprocate in the clamping die. The switching device 120 is an air cylinder, and can be replaced by an oil cylinder or a stepping motor.

On the basis, as shown in fig. 1, the die clamping device comprises a die clamping cylinder 110 and a die clamping plate 111 arranged on a push rod of the die clamping cylinder 110; the die clamping plate 111 is provided with two die clamping pressing blocks 112; the clamping die is positioned between the two clamping die pressing blocks 112; an inclined pressing block 113 for clamping the clamping die is also arranged between the two clamping die pressing blocks 112. The die clamping oil cylinder 110 provides pressure for pressing the clamping die, and can be replaced by an air cylinder or a torque motor.

On the basis of the above, as shown in fig. 1, the contact surface of the clamping die pressing block 112 and the inclined pressing block 113 is an inclined surface. The die clamping oil cylinder 110 pushes the die clamping plate 111 to move forwards, the force of the inclined plane piece in the horizontal direction is converted into the force in the vertical direction, and the die clamping pressing block 112 extrudes the inclined pressing block 113, so that the die is pressed tightly. The larger the included angle between the inclined plane and the horizontal plane is, the larger the extrusion force of the clamping die pressing block 112 to the inclined pressing block 113 is.

On the basis of the above, as shown in fig. 1, the clamping die comprises an upper clamping die 122 and a lower clamping die 121; the upper clamping die 122 and the lower clamping die 121 are both provided with semicircular grooves, the radiuses of the two semicircular grooves are equal, and the gap between the upper clamping die 121 and the lower clamping die 122 is a channel through which the pipe passes when the upper clamping die 121 and the lower clamping die 122 are spliced. The radius of the semicircular groove on the upper clamping die 122 and the lower clamping die 121 is the radius of the pipe to be processed, and the corresponding upper clamping die 122 and the corresponding lower clamping die 121 are selected according to the radius of the plate to be processed.
