Embodiment 1

[0054] This embodiment provides a twisting and bending mechanism for a wiper connecting rod, which is used for twisting a workpiece with a metal plate and wire structure in the XZ plane, such as figure 1 and figure 2 As shown, the workpiece 10 includes a first end portion 11 , a second end portion 12 , and a clamping portion 13 and a kink portion 14 located between the first end portion 11 and the second end portion 12 . The twisting and bending mechanism includes: a conveying module 20 , a first translation driving member 30 , a second translation driving member 40 , a kinking module 50 and a clamping module 60 .

[0055] Please refer to image 3 The conveying module 20 is used for intermittently conveying the workpiece 10 , a clamp 21 is installed on the conveying module 20 to clamp the first end 11 of the workpiece, and the second end 12 of the workpiece extends out of the conveying module 20 along the Y-axis direction. The conveying module 20 may select a turntable whic...

Embodiment 2

[0072] Please refer to image 3 and Figure 5The difference between this embodiment and Embodiment 1 is that a support stand 57 is installed on the bottom plate 31 , and the motor base 52 can slide up and down relative to the support stand 57 . A vertical second guide rail 571 is installed on the support stand 57 ; a guide block 521 matched with the second guide rail 571 is installed on the motor base 52 .

[0073] An upper limit block 572 is installed on the top of the support stand 57 , and a lower limit block 522 is installed on the side wall of the motor base 52 .

[0074] The other structures of this embodiment are the same as those of the first embodiment.

[0075] The following describes the torsional bending method of the workpiece:

[0076] 1. Clamp the first end 11 of the workpiece in the fixture 21 on the conveying module, and the conveying module 20 transfers the workpiece 10 to the top of the clamping module;

[0077] 2. The first translation driver 30 drives ...

Abstract

The invention discloses a torsional bending method and a bending mechanism of a connecting rod of a wiper. The conveying module thereof conveys workpieces intermittently; For bending parts, there is a card slot inside the bending part to clamp the twisted part of the workpiece. The telescopic driving part pushes the bending part so that the bending part clamps the workpiece. The action direction of the telescopic driving part is perpendicular to the axial direction of the rotating driving part; The clamping module clamps the workpiece when bending the workpiece. The clamping module includes the first lifting drive part, the guide seat and the clamping part; the first lifting drive part is installed on the guide seat horizontally, and the first lifting drive part is connected to the clamping part There is an inclined guide hole on the guide seat, and a roller matching the guide hole is installed on the clamping part, and the first lifting drive part pushes the clamping part horizontally, so that the roller moves along the guide hole to change the height of the clamping part. To avoid the workpiece before / after processing. The invention can automatically twist the workpiece, has strong applicability and compact structure.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a torsional bending method and a bending mechanism of a wiper connecting rod. Background technique [0002] According to the needs of the product structure, the processing of metal workpieces also has a variety of processing types. For example, some metal workpieces need to be twisted and bent at a set angle, so that the workpiece is bent in a spiral shape. [0003] For example, the patent publication number CN110340221B discloses a mechanical device for making a wiper connecting rod, which includes an oblique bending mechanism for bending the plate wire along the width direction. The oblique bending mechanism includes an oblique bending frame and a second rotating sleeve, the oblique bending frame is cylindrical, and the end surface of the oblique bending frame is provided with two ends penetrating through and capable of accommodating a plate. A second limit groove with a line w...
