Description

Technical Field

[0001] The invention relates to the technical field related to wiper connecting rod processing, and in particular to an automatic bending device for producing wiper connecting rods. Background Art

[0002] When producing the wiper rod of the front windshield of the car, a rough blank is formed by stamping, and then a series of processes are performed to form the wiper rod, and a bending device is required during the processing.

[0003] Although there are many types of bending devices for producing wiper connecting rods, there are still some shortcomings in use. The spacing between the positioning groove and the top rod of the existing bending tool is fixed, which is not convenient for controlling the bending position of the extension rod. Moreover, the positioning groove is easily stretched and deformed after long-term use, resulting in reduced positioning effect of the extension rod.

[0004] In order to overcome the above defects, a bending tool for a wiper arm extension rod disclosed in the prior art (application number CN202222979381.5, published on 2023-01-17 Chinese patent) can be referred to. The bending tool can not only form different bending lengths for the extension rod by adjusting the position of the sliding seat; but also effectively prevent the deformation of the limit groove by applying pressure to both sides of the sliding block by the card slot of the pressing block;

[0005] And reference can be made to a bending device for a hook arm for a wiper disclosed in the prior art (Chinese patent application number CN202320743062.6, published on August 18, 2023). The second gear of the bending mechanism is used for transmission, and the fixed plate on the second gear drives the fixed rod through the rotation of the second gear, thereby driving the clamping block. At this time, the curvature of the wiper arm in the clamping block begins to change under the action of increased pressure, thereby realizing the bending of the wiper arm. At the same time, the second fixed rod rotates through the center of the circle, continuously extruding and correcting the wiper arm in the arc-shaped fixed strip, thereby improving the reinforcement of the wiper arm angle and the production quality of the wiper arm.

[0006] At the same time, reference can be made to the prior art (Chinese patent with application number CN202221823857.X and publication date 2023-08-18), which discloses a bending mechanism of a bending machine. The bending mechanism clamps and fixes the bending upper die through a fixed chuck, and then fixes the mounting plate on the base with bolts to complete the installation of the bending upper die and the bending lower die on the bending machine. The installation of the bending upper die and the bending lower die is completed.

[0007] Although the above-mentioned prior art can bend the wiper links on the market, there are still certain shortcomings in the working process. After the end position of the wiper link is limited, the wiper link will be deformed during the bending process, which also causes the position of the link to change. If the two ends of the link are limited, the link may break. Therefore, it is necessary to ensure that the breakage is prevented during the processing.

[0008] Therefore, we propose an automated bending device for producing wiper rods to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-Figure 10 , the present invention provides the following technical solutions:

[0040] Embodiment 1: In order to solve the problem that after the bending machine on the current market limits the end position of the wiper connecting rod, the wiper connecting rod will be deformed during the bending process, which will also drive the connecting rod to change its position. If the two ends of the connecting rod are limited, it may cause the connecting rod to break. Therefore, it is necessary to ensure that the connecting rod is prevented from breaking during the processing. Please refer to the attached Figure 1 -Attached Figure 4 , Attachment Fig. 9 and attached Fig.10 ; It includes a base 1 fixed in a horizontal plane, a manipulator assembly 2 for easy picking and placing is fixed at the top side of the base 1, and a control panel 3 for easy control of work start and stop is also fixed at the top front side of the base 1; it also includes: a guide assembly 4 for conveying the wiper connecting rod is fixed at the top position of the base 1, a drive motor 5 is fixed at the right side of the guide assembly 4, the bottom position of the drive motor 5 is installed at the top position of the base 1 by bolts, the output end position of the drive motor 5 is fixed at the end of a two-way threaded rod 6, a stabilizing assembly 8 is threadedly connected to the outer side of the left end of the two-way threaded rod 6, a baffle member 9 is arranged at the left side position of the stabilizing assembly 8, the front and rear sides of the stabilizing assembly 8 and the baffle member 9 are slidably arranged on the inner side of two sets of guide rails 10, the bottom position of the guide rail 10 is fixed to the top of the base 1 by bolts, a bending assembly 7 is fixed to the middle rear side of the baffle member 9 and the stabilizing assembly 8, and the bottom of the bending assembly 7 is fixed to the top rear side of the base 1. The bending assembly 7 is composed of a group of hydraulic push rods fixed on the top of the base 1, a "U"-shaped extrusion block connected to the output end of the hydraulic push rod, and a rolling element rollingly arranged inside the extrusion block, and the inner size of the extrusion block is larger than the thickness of the wiper connecting rod. The baffle member 9 includes a third vertical plate 91 fixed on the left side of the top of the base 1, and two groups of limit grooves 92 are opened on the top of the third vertical plate 91, and a baffle plate 93 is slidably arranged inside the limit groove 92, and two groups of elastic telescopic rods 94 are fixed on the back of the baffle plate 93, and the tail end of the elastic telescopic rod 94 is fixed on the top side wall of the third vertical plate 91.

[0041] When the end of the wiper link is pressed against the side of the baffle member 9, the side position of the baffle plate 93 is squeezed by the wiper link, so that the baffle plate 93 will move its position through the limit groove 92. At this time, the side of the baffle plate 93 will squeeze one side of the elastic telescopic rod 94, and then the wiper link is tightened by the provided stabilizing component 8. When bending, the bending component 7 can be controlled by the control panel 3 to work, so that the output end of the hydraulic oil rod can drive the extrusion block to move, so that the outer side of the extrusion block can extrude and bend the side of the wiper link. In addition, a roller is provided on the inner side of the extrusion block to reduce the friction generated during the bending process. During the bending process of the wiper link, the positions of the two ends of the wiper link change. At this time, the end of the wiper link will be reset and moved by the elastic telescopic rod 94. The setting of the elastic telescopic rod 94 can prevent the wiper link from breaking due to excessive curvature during bending.

At this time, the roller 425 will drive the rotating frame 424 to move through the moving rod 423, so that one end of the moving rod 423 drives the connecting spring 422 to move its position inside the fixed cylinder 421, and the outer side of the roller 425 will be stably attached to the outer side of the wiper link. Then, by starting the driving motor 426, the output end of the driving motor 426 can drive the roller 425 to rotate, and the wiper link can be driven to move its position through the outer side of the roller 425, so that the top end of the wiper link is against the side of the baffle member 9, so that the placement and taking of the wiper link can be convenient.
