Embodiment 1

[0039] The present invention provides a typical specific embodiment, and the structure proposed in this embodiment will be described in detail below in conjunction with specific drawings.

[0040] Such as figure 1 As shown, a round tube symmetrically distributed bilateral intersecting line one-time blanking forming device includes a driving device and a composite mold; the composite mold includes a punching die, a trapezoidal die and a positioning die; the trapezoidal die is arranged on the driving device; the punching die 10 Including the first sub-punch and the second sub-punch, the first sub-punch and the second sub-punch have the same structure, are symmetrically installed in a mounting seat, and the first sub-punch can automatically return under the drive of the first return device ; The second sub-punch can automatically return under the drive of the second return device; the movement direction of the second sub-punch and the second sub-punch is perpendicular to the move...

Embodiment 2

[0051] This implementation also provides a method for processing using the device disclosed in Example 1, as follows:

[0052] Insert the round pipe or square pipe into the mold cavity of the positioning die 6, so that the die knives on the first die and the second die extend into the nozzle of the round pipe or square pipe to be processed, and then the hydraulic rod pushes the trapezoidal block 6 to Forward movement, because the V-shaped groove is formed in the middle of the two dies, the trapezoidal block 6 will push the two dies to move to both sides along the direction of the guide rail, at this time, the die knife can punch the nozzle of the conduit; finally, after the punching is completed, the hydraulic pressure The rod drives the trapezoidal block to reset, and at the same time, the two dies are reset by the elastic force of the spring.

[0053] The punching die in the present invention is pressed in the middle position by the spring, and the guide column and the fixin...

Abstract

The invention discloses a circular tube symmetric distribution bilateral intersecting line one-time blanking forming device and method. The device comprises a driving device and a composite die, wherein the composite die comprises a stamping die, a trapezoid die and a positioning die; the trapezoid die is arranged on the driving device; the stamping die comprises a first sub stamping die and a second sub stamping die; the first sub stamping die and the second sub stamping die are the same in structure and are mounted in a mounting seat in bilateral symmetry; the first sub stamping die is driven by a first returning device to automatically return; the second sub stamping die is driven by a second returning device to automatically return; the motion direction of the first sub stamping die and the second sub stamping die is perpendicular to that of the trapezoid die; and a die cavity is formed in the positioning die for fixing a to-be-processed workpiece.

Description

technical field [0001] The invention relates to a one-time punching and forming device and method for symmetrically distributed double-sided intersecting lines of a circular tube. Background technique [0002] Blanking is a common metalworking process. The inventor found that traditional punching is hydraulic vertical downward punching, especially when it is required to punch a workpiece on both sides, it needs to be manually turned over and punched twice. The symmetrical error of the bilateral intersecting line of blanking is large, and the production efficiency is low. Can not well meet the actual production requirements. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the invention discloses a one-shot punching and forming device and method for circular tubes with symmetrically distributed bilateral intersecting lines. [0004] The first object of the present invention is to propose a one-time punching and formin...
