Description

Technical Field

[0001] This utility model relates to the field of CNC sheet metal bending machines, and in particular to a CNC sheet metal bending machine with an easily replaceable bending table. Background Technology

[0002] A CNC sheet metal bending machine is a metal sheet processing device that uses a CNC system to precisely control the bending angle, depth, and position. The CNC axes of this machine are mainly divided into three categories: Y1 and Y2 axes drive the up-and-down movement of the slide to achieve the main working stroke of the bending machine; X1, X2, Z1, Z2, and R axes serve as back gauge positioning control axes; and the V-axis controls the amount of convexity added to the worktable along the bending line for bending deflection compensation. Standard configuration bending machines generally have "3+1" axes, namely Y1, Y2, X, and V axes, while other CNC axes can be selected by the user according to actual needs. During the operation, the V-axis moves first, generating a certain amount of convexity on the worktable according to the CNC system's settings to compensate for deflection. Then, the X-axis moves to the position set by the CNC system to achieve precise bending and positioning of the workpiece. Next, based on the Y-axis downward movement calculated by the CNC system, the hydraulic cylinder drives the slider (along with the mold) to descend to the given depth inside the die to bend and shape the workpiece. Finally, the return stroke is performed, and the above actions are repeated until the processing of the required workpiece is completed.

[0003] In practical applications of CNC sheet metal bending machines, the bending table is typically fixed to the frame using various fasteners. The use of multiple fasteners means that operators must invest more time and effort in disassembling and installing each fastener individually when replacing or maintaining the bending table. This process is not only tedious but also prone to errors; if a fastener is not installed correctly, it may affect the stability and accuracy of the bending table.

[0004] Problems such as rust, wear, or damage that may exist on the fasteners themselves will further increase the difficulty of replacement. For example, rusted fasteners may require special tools or methods to disassemble, while worn or damaged fasteners may need to be replaced with new ones, which will lead to increased maintenance costs and extended downtime.

[0005] Because bending tables are typically heavy and require precise alignment with their mounting positions on the frame, replacement or installation often necessitates the collaboration of multiple people or the use of lifting equipment. This not only increases the complexity of the operation but may also introduce safety risks. Utility Model Content

[0006] The main objective of this invention is to provide a CNC sheet metal bending machine with an easily replaceable bending table, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A CNC sheet metal bending machine with an easily replaceable bending table includes a bending table base frame and through holes, wherein a plurality of the through holes are equidistantly distributed on the bending table base frame; The lower end of the bending table base frame is connected to a support platform via a support frame, and the lower end of the support platform is provided with a slide table. The lower end of the slide table is provided with a track, and the end face of the track is provided with mounting holes. Fasteners are inserted into the notches at both ends of the support platform and pass through the mounting holes to fix it to the track. The bending table base frame slides along the track to achieve position adjustment. The side wall of the support frame is connected to a sleeve via a bracket, and quick connectors and replaceable connectors are inserted into the upper and lower openings of the sleeve. A handle is connected to the outer end of the quick connector. By rotating the quick connector through the handle, the bending table components on the bending table base frame are fixed.

[0009] Compared with the prior art, the present invention has the following beneficial effects: Thanks to its support mechanism design, the bending table base can easily slide on the track, enabling quick and precise position adjustments. This sliding design not only improves work efficiency but also ensures operational accuracy. Meanwhile, the I-shaped design of the support frame and the inclusion of anti-slip rubber strips further enhance the stability and safety of the equipment, preventing slippage during operation.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 - Figure 4 As shown, a CNC sheet metal bending machine with an easily replaceable bending table comprises a bending table base 7 with multiple equidistantly distributed through holes 8 and one through hole 8. These through holes 8 are evenly distributed on the bending table base 7 to facilitate various operations. The lower end of the bending table base 7 is connected to a support platform 4 via a support frame 6, and the lower end of the support platform 4 is provided with a slide 3. The lower end of the slide 3 is further provided with a track 1, and the end face of the track 1 has mounting holes 2 for further fixing and adjustment.

[0015] Fasteners 5 are inserted into the notches at both ends of the support platform 4 and pass through the mounting holes 2 to fix it to the rail 1, thereby allowing the bending table base 7 to slide along the rail 1 to adjust its position. This design allows the bending table base 7 to slide easily on the rail 1, thus achieving quick and precise position adjustment.

[0016] A sleeve 10 is connected to the side wall of the support frame 6 via a bracket 9. The upper and lower openings of the sleeve 10 are respectively into which a quick-connector 11 and a replaceable connector 13 are inserted. A handle 12 is connected to the outer end of the quick-connector 11. Rotating the handle 12 causes the quick-connector 11 to rotate, thereby securing the bending table components on the bending table base frame 7. This design makes replacing bending table components very convenient and quick.

[0017] The bending table base frame 7 and the support frame 6 are fixed together with bolts to ensure structural stability. The support frame 6 has an "I"-shaped cross-section, which is not only aesthetically pleasing but also provides high strength and stability. Furthermore, anti-slip rubber strips are provided at the connection between the support frame 6 and the bending table base frame 7 to prevent slippage during operation and ensure operational safety.

[0018] The support platform 4 and the slide 3 are designed as a single unit. The slide 3 is connected to the track 1 for limiting, ensuring accuracy and stability during sliding. Multiple mounting holes 2 are equidistantly distributed on the track 1. The openings of the mounting holes 2 are arc-shaped to facilitate the insertion and fixing of the fasteners 5. The fasteners 5 include bolts, nuts, and anti-slip washers. The bolts pass through the notches in the support platform 4, through the mounting holes 2, and are fixed by the nuts and anti-slip washers, thereby ensuring the stability of the entire structure.

[0019] Two sets of sleeves 10 are mounted on the bracket 9, and the end faces of the sleeves 10 have upper and lower openings. Quick-connectors 11 are inserted into the upper openings of the two sets of sleeves 10, while replaceable connectors 13 are inserted into the lower openings of the two sets of sleeves 10. The replaceable connectors 13 and quick-connectors 11 are connected to the sleeves 10 by threads, thereby realizing the function of quick replacement and fixation of the bending table components.

[0020] The quick-connector 11 includes a screw and a connector, with the connector located at the end of the screw.
