Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for CNC bending machines, specifically a multi-station synchronous bending auxiliary device for CNC bending machines. Background Technology

[0002] CNC bending machines, with their high precision and high degree of automation, are widely used in the field of sheet metal processing. In actual production, small, batch-sized metal workpieces often require the same or similar bending processes. Traditional CNC bending machines typically use a single-station processing method when processing these workpieces, meaning that only one workpiece can be fixed on the worktable for bending at a time. After processing, the workpiece is removed and replaced with a new one for the next cycle. This processing method has the following disadvantages: Low processing efficiency: Since only one workpiece can be processed at a time, a lot of time needs to be spent on workpiece replacement and equipment adjustment for mass production, resulting in low overall processing efficiency and difficulty in meeting production schedule requirements.

[0003] High labor intensity: Operators need to frequently perform operations such as loading, unloading, positioning and clamping of workpieces. Long-term work can easily lead to fatigue and increase labor intensity. At the same time, operational errors can easily affect the processing quality.

[0004] Unstable machining accuracy: In multi-workpiece machining, each workpiece change requires repositioning and adjustment. Due to variations in human operation, it is difficult to guarantee the consistency of positioning accuracy and bending parameters for each workpiece, resulting in unstable workpiece accuracy and a low pass rate. Therefore, it is necessary to design a multi-station synchronous bending auxiliary device for CNC bending machines. Utility Model Content

[0024] Please see Figures 1-4 This utility model discloses a multi-station synchronous bending auxiliary device for a CNC bending machine, including a base 1, a station adjustment mechanism, a synchronous drive mechanism, and a positioning and clamping mechanism. The base 1 is located on one side of the workbench 2 of the CNC bending machine and is used to support the entire auxiliary device; The workstation adjustment mechanism is mounted on the base 1 and includes at least two workstation components 3. The workstation components 3 can slide along the length direction of the base 1. The base 1 is provided with a slide rail 11 along its length direction. The bottom of the workstation components 3 is provided with a slider 12 that matches the slide rail 11. The slider 12 is slidably mounted on the slide rail 11. Each workstation component 3 is provided with a support platform 4 for placing the workpiece. The upper surface of the support platform 4 is provided with an anti-slip pad 13, and the surface of the anti-slip pad is provided with anti-slip texture to prevent the workpiece from shifting during processing.

[0025] In this invention, the synchronous drive mechanism includes a drive motor 5 and a synchronous transmission rod 6. The drive motor 5 is mounted at one end of the base 1, and the synchronous transmission rod 6 is arranged along the length of the base 1. One end of the synchronous transmission rod 6 is fixedly connected to the output end of the drive motor 5. The synchronous transmission rod 6 is provided with a transmission protrusion 7 corresponding to the workstation assembly. The transmission protrusion 7 is engaged with the bottom of the workstation assembly 3. When the drive motor 5 drives the synchronous transmission rod 6 to rotate, the transmission protrusion pushes the workstation assembly to slide synchronously along the base. When the drive motor is started, the motor drives the synchronous transmission rod to rotate at a constant speed, and the transmission protrusion pushes the workstation assembly to slide synchronously along the slide rail.

[0026] In this utility model, the positioning and clamping mechanism includes a positioning block 8 and a clamping assembly. The positioning block 8 is disposed on one side of the support platform 4. The clamping assembly includes a clamping cylinder 9 and a clamping block 10. The clamping cylinder 9 is installed on the other side of the support platform 4. The clamping block 10 is connected to the piston rod of the clamping cylinder 9. A buffer pad 14 is provided on the inner side of the clamping block 10. During debugging, the air intake pressure of the clamping cylinder 9 is controlled so that the clamping block 10 can stably clamp the workpiece without significant deformation of the workpiece, while ensuring that the cylinder extension and retraction action responds quickly.

[0027] In this invention, the support platform 4 includes a fixed base 41 and a movable support layer 42. The fixed base 41 is fixedly connected to the top of the workstation assembly 3, and the movable support layer 42 is disposed above the fixed base 41. The fixed base 41 has at least two threaded holes 43 evenly distributed along its length. The movable support layer 42 has through-hole adjustment holes 44 corresponding to the positions of the threaded holes 43. Adjusting bolts 45 pass through the adjustment holes 44 and are threadedly connected to the threaded holes 43, with the top of the adjusting bolts 45 flush with the upper surface of the movable support layer 42. This structure can accommodate workpieces of different thicknesses, meeting the placement requirements of various workpiece specifications without replacing the support platform, thus improving the versatility of the device. The threaded adjustment structure ensures the accuracy of height adjustment, preventing workpiece bending accuracy from being affected by support height deviations.

[0028] Working Principle: The base of the device is fixed to one side of the CNC bending machine's worktable, providing stable support for the entire system. The operator places the workpieces to be processed on the support platforms of each station component. The anti-slip pads and textured surfaces of the support platforms prevent workpiece displacement. Then, the positioning and clamping mechanism is activated. The positioning block on one side of the support platform initially positions the workpiece, while the clamping cylinder on the other side pushes the clamping block towards the workpiece until it is clamped. The buffer pad inside the clamping block prevents the workpiece from deforming under pressure. The drive motor of the synchronous drive mechanism is then activated, driving the synchronous transmission rod, which runs along the length of the base, to rotate. The transmission protrusion on the synchronous transmission rod engages with the bottom of the station component. As the transmission rod rotates, the transmission protrusion pushes all station components to slide synchronously. The slider at the bottom of the station component cooperates with the slide rail on the base to ensure a stable sliding trajectory, allowing the workpieces at each station to enter the processing area of ​​the CNC bending machine synchronously and complete the bending operation. After bending, the drive motor reverses direction, driving the station components back to their original position along the slide rail via the synchronous transmission rod. Then, the clamping cylinder drives the clamping block to retract, and the operator removes the processed workpiece, allowing the next batch of workpieces to be processed.

[0029] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
