Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically to a bending device for a windshield wiper hook arm. Background Technology

[0002] A windshield wiper arm bending device is an automated or semi-automated machine specifically designed to process raw materials (such as metal wire) into specific hook shapes. Through mechanical positioning, clamping, and power drive, it achieves precise bending of the arm to match the assembly requirements of the windshield wiper.

[0003] A search revealed a Chinese patent application for a bending device for a windshield wiper arm. The device includes a platform with a groove on its upper surface. A clamping block is slidably connected within the groove, and a windshield wiper arm is engaged within the clamping block. A first connecting hole is located on the upper surface of the platform, and a first connecting rod is fitted into the first connecting hole. When the motor is started, the center of a first gear rotates, simultaneously driving a second gear. A fixing plate on the second gear pushes the fixing rod through the rotation of the second gear, thereby driving the clamping block. Under increased pressure, the windshield wiper arm within the clamping block changes its curvature, bending the wiper arm. Simultaneously, the rotation of the second connecting hole continuously compresses and corrects the windshield wiper arm within the curved fixing strip, improving the reinforcement of the wiper arm angle and the production quality of the wiper arm, thus ensuring the practicality of the device.

[0004] In the aforementioned prior art, the clamping block is driven to rotate by a motor, thereby bending the wiper arm by rotating the block. Although this bending method has a certain bending effect, the force of rotation is uneven when bending by rotation, and the wiper arm is also prone to movement when rotating and squeezing, thus affecting the bending effect. Utility Model Content

[0005] The purpose of this utility model is to provide a bending device for a windshield wiper hook arm, which solves the problem that the bending effect of the existing windshield wiper hook arm bending device is poor and the windshield wiper is easy to move during the bending process.

The lower end of the guide rail is fixedly connected to the base plate, and an insert block is fixedly connected to the inner side of the lower end of the sleeve plate. The end of the insert block away from the sleeve plate is inserted into the guide rail.

[0011] The above technical solution utilizes the movement of the insert block within the guide rail to restrict the movement of the sleeve plate.

[0012] As a preferred embodiment of the above technical solution, the adjustment component includes a second limiting plate fixedly connected to the upper side of the bottom plate away from the positioning plate, and a motor fixedly connected to the end of the second limiting plate away from the positioning plate. The output shaft of the motor passes through the second limiting plate and is fixedly connected to a threaded rod. Both ends of the threaded rod are rotatably connected to the second limiting plate through flanges, and a threaded plate is threadedly engaged on the outer side of one end of the threaded rod.

[0013] As a preferred embodiment of the above technical solution, the pressing assembly includes a fixed plate fixedly connected to the end of the threaded plate away from the threaded rod, and a push rod fixedly connected to one side of the fixed plate, and a second pressure plate fixedly connected to the end of the push rod away from the fixed plate.

[0014] As a preferred embodiment of the above technical solution, the slider is configured to be convex, and a convex groove is formed inside the first limiting plate.

[0015] The above technical solution involves setting the slider to a convex shape and opening a convex groove in the first limiting plate, which facilitates the slider sliding within the first limiting plate and restricts the movement of the first pressure plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This is a bending device for a windshield wiper arm.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a bending device for a windshield wiper arm, including a base plate 1, a positioning plate 11 fixedly connected to the upper side of one end of the base plate 1, a positioning component 2 provided on the upper side of the base plate 1 near the positioning plate 11, and the positioning component 2 including a mounting plate 21 provided on the upper side of the base plate 1 near the positioning plate 11, a placement plate 22 fixedly connected to one end of the mounting plate 21, an elastic component 3 provided on the end of the placement plate 22 away from the mounting plate 21, a limiting component 4 provided on one end of the elastic component 3, a sliding component 5 provided on the lower side of the mounting plate 21, and an adjusting component 6 provided on the end of the base plate 1 away from the positioning plate 11, with pressing components 7 provided at both ends of the adjusting component 6. By cooperating with the positioning component 2 and the elastic component 3, the bending effect of the windshield wiper can be effectively improved, and the stability of the windshield wiper during bending can be improved, thereby improving processing efficiency.

[0021] like Figure 2 As shown, the elastic component 3 includes a first pressure plate 31 fixedly connected to one side of the placement plate 22, and a spring 32 fixedly connected to the end of the first pressure plate 31 away from the placement plate 22. The wiper hook arm is placed in the two sets of first pressure plates 31. When placed, the hook arm presses the first pressure plates 31 at both ends.

[0022] like Figure 3 As shown, the limiting component 4 includes a first pressure plate 31 with a slider 41 fixedly connected to one end, and a first limiting plate 42 is sleeved on the outer side of the slider 41 away from the first pressure plate 31. The lower end of the first limiting plate 42 is fixedly connected to the placement plate 22, and the first pressure plate 31 drives the slider 41 to move within the first limiting plate 42.

[0023] like Figure 2 As shown, the sliding assembly 5 includes a mounting plate 21 with a sleeve plate 51 fixedly connected to its lower side, and a guide rail 52 is sleeved on the lower end of the sleeve plate 51. The lower end of the guide rail 52 is fixedly connected to the base plate 1, and an insert block 53 is fixedly connected to the inner side of the lower end of the sleeve plate 51. The end of the insert block 53 away from the sleeve plate 51 is inserted into the guide rail 52. After the wiper hook arm moves, the mounting plate 21 and the sleeve plate 51 are moved by the positioning of the placement plate 22 and the first limiting plate 42, so that the sleeve plate 51 moves under the restriction of the insert block 53 and the guide rail 52.

[0024] like Figure 4As shown, the adjustment assembly 6 includes a second limiting plate 61 fixedly connected to the upper side of the base plate 1 away from the positioning plate 11, and a motor 62 fixedly connected to the end of the second limiting plate 61 away from the positioning plate 11. The output shaft of the motor 62 passes through the second limiting plate 61 and is fixedly connected to a threaded rod 63. The two ends of the threaded rod 63 are rotatably connected to the second limiting plate 61 through flanges. A threaded plate 64 is threadedly engaged on the outer side of one end of the threaded rod 63. The motor 62 is started under the support of the second limiting plate 61. After the motor 62 starts, the output shaft drives the threaded rod 63 to rotate. After the threaded rod 63 rotates, it engages with the threaded plate 64.

[0025] like Figure 1 As shown, the pressing assembly 7 includes a fixed plate 71 fixedly connected to one end of a threaded plate 64 away from the threaded rod 63, and a push rod 72 fixedly connected to one side of the fixed plate 71. A second pressure plate 73 is fixedly connected to one end of the push rod 72 away from the fixed plate 71. The threaded plate 64 drives the fixed plate 71 to push the push rod 72 to move, thereby allowing the push rod 72 to push the second pressure plate 73 to move. After the second pressure plate 73 moves, it pushes the clamped wiper hook arm to move.

[0026] like Figure 3 As shown, the slider 41 is convex, and a convex hole groove is opened inside the first limiting plate 42. The first pressure plate 31 drives the slider 41 to move within the first limiting plate 42.

[0027] Working principle: When bending the wiper arm, the wiper arm is first placed between two sets of first pressure plates 31. During placement, the arm presses against the first pressure plates 31 at both ends, causing the first pressure plates 31 to move the slider 41 within the first limiting plate 42. After the first pressure plates 31 move, they compress the spring 32, thus using the elastic potential energy of the spring 32 to press against the first pressure plates 31, restricting the arm. Then, with the support of the second limiting plate 61, the motor 62 is started. After the motor 62 starts, its output shaft drives the threaded rod 63 to rotate. The rotating threaded rod 63 then... Through the threaded engagement with the threaded plate 64, the threaded plate 64 drives the fixed plate 71 to push the push rod 72 to move, thereby causing the push rod 72 to push the second pressure plate 73 to move. After the second pressure plate 73 moves, it pushes the clamped wiper hook arm to move. After the wiper hook arm moves, it drives the mounting plate 21 and the sleeve plate 51 to move through the positioning of the placement plate 22 and the first limiting plate 42. This allows the sleeve plate 51 to move under the restriction of the insert block 53 and the guide rail 52. When the wiper hook arm is pushed to the positioning plate 11, the wiper hook arm bends due to the restriction of the positioning plate 11.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
