Description

Technical Field

[0002] In the process of hardware accessories processing, the workpiece stabilization device is a key component to ensure processing accuracy and efficiency. With the continuous advancement and increase in complexity of manufacturing processes, the requirements for workpiece stabilization devices are becoming higher and higher. Traditional workpiece fixing methods often rely on simple fixtures or support devices. Although these methods can provide basic stability, in high-precision processing and mass production, problems such as workpiece displacement, vibration or uneven pressure may occur, thus affecting processing quality and production efficiency; There are still the following defects in specific use: 1. The deviation will cause the dimensional accuracy of the bent parts to not meet the design requirements, thus affecting the overall quality and performance of the product. At the same time, the deviation may cause the appearance of the bent parts to be distorted and uneven, affecting the aesthetics and market acceptance of the product. The bent parts with serious deviation may need to be discarded or reprocessed, which will directly increase the scrap rate and production costs.

[0003] 2. In addition, if the operator cannot accurately judge the positioning or bending angle of the workpiece due to visual errors, the size of the workpiece after bending will deviate from the design requirements, affecting the overall quality and precision of the product. At the same time, inaccurate judgment may lead to uneven force applied during the bending process, causing the workpiece to twist and deform, affecting the appearance and performance of the product.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention utilizes a short contact plate and a long contact plate to cooperate with each other. The shorter contact portion first contacts one end of the workpiece to be bent, playing a role in preliminary positioning. This helps to ensure the position accuracy of the workpiece before bending and lays the foundation for subsequent bending operations. At the same time, as the bending process proceeds, the longer contact portion subsequently contacts the workpiece to further guide the bending direction of the workpiece. This sequential contact design helps to achieve accurate bending of the workpiece and prevents displacement or distortion during the bending process. Secondly, during the bending process, the workpiece will be subjected to greater stress. Through the design of a long and a short sequential contact, the stress can be more effectively dispersed, thereby reducing the risk of deformation or cracks in the workpiece at the bending point. The longer contact portion provides stable support for the workpiece in the later stage of bending, which helps to reduce deformation problems caused by the workpiece being suspended or insufficiently supported. At the same time, this design also helps to prevent the workpiece from being damaged unnecessary during the bending process. Finally, the long and short sequential contact mechanism design helps to optimize the bending path of the workpiece, making the bending process smoother and more efficient, which can not only shorten the processing time, but also improve the processing accuracy and product quality. (2) The present invention uses the engraving pen and the whiteboard to cooperate with each other, and the distributed positioning mechanism can clearly mark the bending position and angle of the bending machine workpiece on the whiteboard, which provides a clear reference for the operator when performing the bending operation, so that they can bend the workpiece to the predetermined angle more accurately. At the same time, after the engraved lines are displayed on the whiteboard, the operator can more easily check whether the bending result meets the requirements, and can make adjustments in time to help reduce the scrap rate and improve production efficiency. In addition, the record of the engraved lines on the whiteboard can be used as a basis for tracing the production process, so that timely measures can be taken to speed up production efficiency. Finally, by observing the engraved lines on the whiteboard, the bending requirements and operation methods of different workpieces can be understood, and the bending technology can be mastered more quickly; (3) The present invention utilizes the cooperation between the rotating roller and the moving plate. The correction roller mechanism can further flatten and trim the bent portion of the workpiece after bending to ensure the flatness and consistency of the bent surface. The correction roller mechanism can also help release and eliminate internal stress while flattening the bent portion, reduce deformation or warping, and thus improve the stability and durability of the workpiece. Furthermore, the correction roller mechanism can complete the two processes of bending and flattening in one processing process, thereby reducing the number of times the workpiece is moved and repositioned, and improving the overall processing efficiency. In addition, the correction roller mechanism can effectively flatten the bending area, reduce the precision error caused by material rebound or uneven pressure, and can help flatten the surface after bending to make it smoother and more uniform, thereby improving the appearance and quality of the workpiece.

[0022] The complete working principle and steps of the above embodiment are as follows: Initial limitation; e.g. Figure 1 As shown, the operator first places the hardware accessories on the workbench 14 and fixes them with the clamping plate 13, then turns the handle to adjust the position and angle of the upper mold 11 and the lower mold 12 as needed, and then ensures that the hardware accessories are aligned with the center line of the mold, and then starts the hydraulic system or other power source, the lower mold 12 flips and moves, and pressure is applied to complete the bending. Finally, after the bending is completed, the formed sheet is taken out.

[0023] When using: The distributed positioning mechanism achieves preliminary positioning by successively contacting the workpiece to guide the bending direction of the accessory. Step 2: like Figures 2 to 4 As shown, when the lower mold 12 flips and moves to realize the bending process of the hardware accessories, the external power interface is energized through the power cord 23, and then the electric telescopic rod 22 starts to extend, thereby the buckle 24 fixedly connected to the outer wall of one end of the electric telescopic rod 22 and the transverse gear 25 rotatably connected to the inside of the buckle 24 will synchronously follow the extension of the electric telescopic rod 22 to undergo transverse displacement, and then the transverse displacement of the transverse gear 25 will push the short contact plate 27 and the long contact plate 29 meshing on the outer wall of the transverse gear 25 to undergo synchronous transverse displacement. Furthermore, due to the different diameter sizes of the short contact plate 27 and the long contact plate 29, when the short contact plate 27 and the long contact plate 29 synchronously undergo transverse displacement to contact one side of the bent corner of the hardware accessories, there will be a staggered conflict between the front and the back. If the bent hardware accessories are close to one side of the short contact plate 27, If a bulge occurs at one end of the hardware accessory, the hardware accessory provides a reaction force to offset the continued movement of the short contact plate 27 until one end of the long contact plate 29 contacts the other side of the hardware accessory. Similarly, if a bulge occurs at one end of the bent hardware accessory close to the long contact plate 29, the hardware accessory provides a reaction force to offset the continued movement of the long contact plate 29 until one end of the short contact plate 27 contacts the other side of the hardware accessory, thereby first contacting the shorter contact portion to complete the bending of the short side, and then contacting the longer contact portion to complete the bending of the long side. First contacting the shorter contact portion to complete the bending of the short side, and then contacting the longer contact portion to complete the bending of the long side. The corner marking mechanism accurately marks the corner position and angle of the accessory in 3 steps: like Figures 5 and 6As shown, when the long contact plate 29 moves laterally, the arc gear 31 meshing with the outer side of the front end of the long contact plate 29 will rotate, and then the eccentric shaft 32 eccentrically fixedly connected to the outer wall of the arc gear 31 will rotate, so that the crank 33 rotatably connected to the outer wall of the eccentric shaft 32 will rotate together with the rotation of the eccentric shaft 32, so the eccentric shaft 35 fixedly connected to the outer wall of one end of the crank 33 will also rotate with the rotation of the crank 33, so the rotation of the eccentric shaft 35 will cause the sleeve block 36 fixedly connected to the outer wall of the eccentric shaft 35 to rotate synchronously, and further, since the connecting column 37 fixedly connected to one end of the sleeve block 36 is slidably connected to the outer wall of the long connecting rod 34, the sleeve block 36 is connected to the outer wall of the long connecting rod 34. The arc groove is designed, so the trajectory of the sleeve block 36 when rotating is an arc sliding inside the arc groove opened on the outer wall of the long connecting rod 34 around the connecting column 37. Therefore, when the curved surface of the bent hardware accessory contacts the surface of the wedge block 38, the arc sliding of the connecting column 37 will cause the wedge block 38 to perform friction arc sliding on the curved surface of the bent hardware accessory, so that the engraving pen 39 fixedly connected to one side of the wedge block 38 will simulate the arc friction sliding of the wedge block 38 on the curved surface of the bent hardware accessory and engrave on the surface of the whiteboard 310, so that the curved angle of the hardware accessory can be judged by observing the engraved line marks on the surface of the whiteboard 310; The correction roller mechanism for further flattening and trimming the bending part of the accessory after bending has 4 steps: like Figures 7 and 8 As shown, when the eccentric shaft 35 rotates, the crank 33 rotatably connected to one side of the bottom end of the eccentric shaft 35 will also rotate, so that the bottom shaft 311 fixedly connected to one end of the crank 33 will rotate synchronously with the rotation of the crank 33, and then the turntable 41 rotatably connected to the outer wall of the bottom end of the bottom shaft 311 will rotate, so that the obstacle column 42 fixedly connected to the surface of the turntable 41 will push the short plate 47 with the rotation of the turntable 41, so that the moving plate 45 fixedly connected to one end of the short plate 47 first slides to the right on the inner wall of the clamping column 44, so that the rotating roller 46 rotatably connected to the outer wall of the moving plate 45 will move to the right with the moving plate 45 When the obstacle column 42 rotates to abut against the raised portion provided on one side of the turn buckle 49, the obstacle column 42 will push the turn buckle 49 to deflect to the left, and then the external column 48 clamped at one end of the turn buckle 49 will be pushed to the left end, thereby the moving plate 45 fixedly connected to the upper end of the external column 48 will move to the left, and thus the rotating roller 46 rotatably connected to the outer wall of the moving plate 45 will move together with the leftward movement of the moving plate 45. In summary, the horizontal reciprocating movement of the moving plate 45 causes the clamping column 44 to move and rub at the bending corner mark after the bending, thereby eliminating the slight fluctuations that may occur during the bending process.
