Description

Technical Field

[0001] This invention relates to the field of automotive parts processing. More specifically, this invention relates to a bending device for automotive parts processing. Background Technology

[0002] With the continuous development of the automotive industry, various brands and models of cars have appeared on the market. Each car requires a large number of spare parts, resulting in a wide variety of spare parts of different shapes and sizes available. For example, [attached text]. Figure 1 The U-shaped workpiece shown has two arc-shaped bends, and the raw material used is a long strip of steel pipe. During processing, the pipe is first bent at one end, then flattened in the middle, and finally bent into a U-shape. Existing equipment can easily handle the first two steps. However, for the final step, which requires machining two arc-shaped bends, the common method is to machine them separately. But machining the two bends sequentially requires positioning the workpiece for each step, which can easily lead to positional deviations. Furthermore, machining both bends in a single operation is difficult with current equipment. Summary of the Invention

[0014] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be noted that in the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] like Figures 1-3 As shown, an embodiment of the present invention provides a bending device for processing automotive parts, including a first positioning block 2, two extrusion rollers 3, two sets of drive mechanisms, a positioning mechanism 4, a lifting mechanism, and a bending component. The upper end of the first positioning block 2 is provided with a long strip-shaped first through groove 5. The bending component is disposed above the first through groove 5 and is drivenly connected to the lifting mechanism. The lower ends of the bending component are respectively provided with arc-shaped pressing ends. The two extrusion rollers 3 are respectively disposed on both sides of the first through groove 5 and are rotatably connected to the two sets of drive mechanisms. The first drive assembly drives the corresponding extrusion roller 3 to move closer to or away from the first positioning block 2. The positioning mechanism 4 is disposed on the side of one set of drive mechanisms away from the first positioning block 2.

[0021] In this embodiment, the flattened workpiece 1 is placed in the first through groove 5, and one end of it is positioned by the positioning mechanism 4. The positioning of workpiece 1 is then completed. The lifting mechanism then moves the bent part downwards, pressing the two pressing ends of the bent part against workpiece 1. Two sets of driving mechanisms then drive the corresponding extrusion rollers 3 towards the first positioning block 2. At this point, the extrusion rollers 3 contact the lower end of workpiece 1 and apply force to it. The extrusion rollers 3 rotate relative to the driving mechanism. During this rotation, the upper part of workpiece 1 is pressed against the arc-shaped pressing end. Under the simultaneous action of the pressing end and the extrusion rollers 3, the portion of workpiece 1 located between them slowly rotates upwards, forming a bent portion that matches the arc-shaped pressing end. Figure 2 and Figure 3 As shown, the positioning mechanism 4 can be a vertical plate, and a positioning groove located on the same line as the first through groove 5 is set at one end of the vertical plate near the drive mechanism. When the workpiece 1 placed in the first through groove 5 is radially positioned, it is only necessary to extend one end of the workpiece 1 into the positioning groove and abut against the vertical plate. In this way, the position of the workpiece 1 to be processed can be limited, thereby ensuring that the processing position of each workpiece 1 is the same.

[0022] Preferably, in another embodiment of the present invention, the driving mechanism includes a first driving component and a sliding block 6. The sliding block 6 is connected to the first driving component in a transmission manner. The first driving component drives the sliding block 6 to slide along the length direction of the first through groove 5. The extrusion roller 3 is rotatably disposed at one end of the sliding block 6 near the first positioning block 2.

[0023] In this embodiment, such as Figure 2 and Figure 3 As shown, the first driving assembly includes a slide rail 9 and a first driving unit 10. The slide rail 9 is arranged along the length direction of the first through groove 5. The sliding block 6 is slidably disposed on the slide rail 9 and is drivenly connected to the first driving unit 10. The first driving unit 10 drives the sliding block 6 to slide along the length direction of the slide rail 9. The first driving unit 10 can use two telescopic cylinders to be drivenly connected to the sliding block 6. The telescopic cylinders drive the sliding block 6 to move, while ensuring the force exerted by the extrusion roller 3 on the workpiece 1 to be processed. A linear guide rail is provided below the sliding block 6, and the sliding block 6 is slidably disposed on the linear guide rail to limit the movement trajectory of the sliding block 6.

[0024] Preferably, in another embodiment of the present invention, the upper end of the sliding block 6 is provided with a second positioning block 7, the extrusion roller 3 is located between the first positioning block 2 and the second positioning block 7, and the upper end of the second positioning block 7 is provided with a second through groove 8 located on the same straight line as the first through groove 5.

[0025] In this embodiment, the bottom wall of the second through groove 8 on the second positioning block 7 is higher than the first through groove 5, so that when the bending part and the extrusion roller 3 process the workpiece 1, the workpiece 1 is limited by the two second through grooves 8.

[0026] Preferably, in another embodiment of the present invention, the bending member includes a moving block 11, a second driving assembly, and two rotating members 12. The moving block 11 is connected to the lifting mechanism. The two rotating members 12 are rotatably disposed on both sides of the lower end of the moving block 11, and each of their sidewalls has a circumferential surface. The circumferential surface constitutes the pressing end. The second driving assembly is disposed on the moving block 11 and is connected to the two rotating members 12 respectively to drive the circumferential surface to rotate around its axis.

[0027] In this embodiment, the rotating component 12 is a horizontally arranged cylinder. The lower end of the moving block 11 has two notches that match the cylinder. The rotating component 12 is disposed in the limiting groove, and its lower end extends below the moving block 11. The rotating component 12 is rotatably connected to the inner wall of the notch via a rotating shaft. The second drive assembly includes two second drive units corresponding to the two rotating components 12 respectively. The second drive unit includes a second telescopic cylinder 16 and a connecting rod 17. The end of the cylinder body of the second telescopic cylinder 16 is rotatably connected to the moving block 11, and its push rod is rotatably connected to the connecting rod 17 disposed on the rotating component 12. By extending and retracting the push rod of the second telescopic cylinder 16, it drives the connecting rod 17 to rotate, thereby driving the corresponding rotating component 12 to rotate. While ensuring the shape of the pressing end, the rotation of the rotating component 12 enhances the pressing effect of the pressing end on the workpiece 1.

[0028] Preferably, in another embodiment of the present invention, the lifting mechanism includes a support plate 13 and a first telescopic cylinder 14. The moving block 11 is slidably disposed on the support plate 13. The cylinder body of the first telescopic cylinder 14 is connected to the support plate 13, and its push rod is vertically downward and connected to the moving block 11.

[0029] In this embodiment, the push rod of the first telescopic cylinder 14 drives the moving block 11 to move up and down, and at the same time, the first telescopic cylinder 14 applies a downward force to the bent part to ensure that the bent part applies a force to the workpiece 1.

[0030] Preferably, in another embodiment of the present invention, the support plate 13 is provided with two vertically arranged limiting strips 15, and the moving block 11 is provided with sliding grooves corresponding to the two limiting strips 15 respectively, and the limiting strips 15 are slidably arranged in the corresponding limiting strips 15.

[0031] In this embodiment, the movement trajectory of the moving block 11 is limited by the limiting strip 15 and the slide rail 9.

[0032] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and embodiments shown and described herein.
