Embodiment 1

[0054] This embodiment provides a torsional bending mechanism of a wiper connecting rod, which is used to twist a workpiece with a metal plate 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 translational driving part 30 , a second translational driving part 40 , a twisting and folding 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 , the fixture 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 protrudes outside the conveying module 20 along the Y-axis direction. The conveying module 20 may be a turntable ...

Embodiment 2

[0072] Please refer to image 3 and Figure 5, The 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, and the guide block 521 cooperates with the second guide rail 571 to guide the lifting motion of the rotary drive member 53.

[0073] The upper limit block 572 is installed on the top of the support stand 57, the lower limit block 522 is installed on the side wall of the motor base 52, and the upward travel of the motor base 52 is physically limited when the lower limit block 522 abuts with the upper limit block 572.

[0074] Other structures of this embodiment are the same as those of Embodiment 1.

[0075] The following describes the torsional bending method of the workpie...

Abstract

The invention discloses a twisting bending method of a windscreen wiper connecting rod and a bending mechanism thereof. A conveying module intermittently conveys a workpiece; a twisting module comprises a rotary driving part, a telescopic driving part and a bending part, the rotary driving part rotates the bending part, a clamping groove is formed in the bending part so as to clamp a twisting part of the workpiece, the telescopic driving part pushes the bending part to enable the bending part to clamp the workpiece, and the action direction of the telescopic driving part is perpendicular to the axial direction of the rotary driving part; a material clamping module clamps the workpiece when the workpiece is bent, and the material clamping module comprises a first lifting driving part, a guide base and a material clamping part; the first lifting driving part is horizontally mounted on the guide base and connected with the material clamping part; and an inclined guide hole is formed in the guide base, a roller matched with the guide hole is mounted on the material clamping part, and the first lifting driving part horizontally pushes the material clamping part to enable the roller to move along the guide hole to change the height of the material clamping part so as to avoid the workpiece before / after machining. According to the twisting bending method of the windscreen wiper connecting rod and the bending mechanism thereof, the workpiece can be automatically twisted, applicability is high, and the structure is compact.

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 product structure, metal workpiece processing also has a variety of processing types. For example, some metal workpieces need to be twisted and bent at a set angle to make the workpiece bend like a spiral. [0003] For example, the patent with the notification 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 a The second limiting groove of the line width, the two sides of one end of the second limiting groove respectiv...
