Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a CNC bending machine with intelligent detection. Background Technology

[0002] CNC bending machines are machines used to bend metals or other materials. They play an important role in industrial production and are commonly used to manufacture various metal products, such as pipes, boxes, and metal plates. Metal plates are flat products made from metal materials through processing. They have advantages such as high strength, corrosion resistance, and good electrical and thermal conductivity, and are widely used in many fields such as construction, shipbuilding, machinery, electronics, and automobiles.

[0003] When a CNC bending machine is working, it uses the upper and lower dies to punch and bend metal sheets, forming U-shaped, L-shaped, Z-shaped, and other structures that can be directly used as the supporting frame for products. Examples include the frame of an electrical distribution box, guardrails for machinery, and load-bearing structures for large equipment, providing basic load-bearing and protective capabilities without additional welding or assembly. In the field of load-bearing plate bending, the thickness and length of the load-bearing plate vary depending on the usage scenario and load. Due to the enormous load, the required thickness of the load-bearing plate may reach tens of millimeters or even more.

[0004] When the bending machine bends this type of load-bearing plate, the pressurization system of the bending machine will operate under overload. This makes it difficult to completely stamp the load-bearing plate into shape during bending. In terms of workpiece forming, because the pressurization system cannot provide continuous, stable and sufficient pressure, it is difficult to completely stamp the load-bearing plate into the ideal shape during the bending process. This leads to defects in the workpiece, such as bending angle deviation and uneven local deformation. The pressurization system of the bending machine operates under overload, and its internal mechanical components will be subjected to excessive stress, accelerating wear and easily causing damage such as seal damage and hydraulic pump failure. To address this, we propose a CNC bending machine with intelligent detection. Utility Model Content

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1:

[0033] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a CNC bending machine with intelligent detection, including a worktable 1. The upper surface of the worktable 1 is provided with a mounting base 2. The mounting base 2 is provided with a split mold assembly 3. The split mold assembly 3 includes several groups of horizontally distributed lifting seats 31. The upper surface of each group of lifting seats 31 is bolted with a lower mold 32. The lower hydraulic cylinder 5 is provided on the lower side of the lifting seat 31 located in the middle. The lifting seats 31 located on both sides are provided with connecting components for connecting adjacent lifting seats 31. The lower hydraulic cylinder 5 is installed inside the worktable 1 by a bracket. The output end of the lower hydraulic cylinder 5 is fixedly connected to the lifting seat 31 located in the middle by a flange.

[0034] A connecting component is provided for connecting adjacent lifting seats 31. During bending operations, the connecting component is used to connect the middle lifting seats 31 in sequence, and the lower hydraulic cylinder 5 is used to punch and bend each part of the load-bearing plate in sequence to ensure that the bending parameters of the load-bearing plate meet the standards and to avoid the problem of the lower hydraulic cylinder 5 increasing its own load due to the overall punching.

[0035] Example 2:

[0036] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the connecting components include an inner groove 311 that runs through the interior of each set of lifting seats 31, and a number of toothed grooves 314 are provided on the inner wall of each set of inner grooves 311.

[0038] In use, the toothed grooves 314 and the locking teeth 315 work together to increase the force transmission area, enhance the gripping force, and strengthen the support effect.

[0039] Specifically, a support member 312 is slidably installed inside the inner groove 311 of the lifting seat 31 on both sides. Several locking teeth 315 are integrally formed on the outer wall of the support member 312. The number and position of the locking teeth 315 correspond one-to-one with the tooth grooves 314. The locking teeth 315 are movably installed in the tooth grooves 314.

[0040] The tooth profile adopts a trapezoidal design (which is more wear-resistant and less prone to disengagement than triangular teeth), and the tooth surface is polished to reduce frictional resistance when mating with the 315 locking tooth.

[0041] The locking teeth 315 are integrally forged onto both sides of the outer wall of the support 312. Not only do their number and position correspond perfectly to the tooth grooves 314, but their tooth height and width also perfectly match the groove depth and width of the tooth grooves 314, achieving an "embedded" fit.

[0042] Specifically, electric actuators 313 are installed on the inner surface of the inner groove 311 of the lifting seats 31 located on both sides, and the output end of the electric actuators 313 is fixedly connected to the support member 312.

[0043] The start-up electric actuator 313 can drive the support member 312 and the locking tooth 315 to move, so that the support member 312 and the locking tooth 315 move from the lifting seats 31 on both sides to the middle lifting seat 31, so that the support member 312 and the locking tooth 315 are inserted into the inner groove 311 and tooth groove 314 of the middle lifting seat 31. This completes the work of the connecting component, so that the lifting seat 31 and the middle lifting seat 31 form a whole with synchronous lifting and lowering movement. With the help of the power of the lower hydraulic cylinder 5, the middle two sides of the load-bearing plate are punched and bent in steps.

[0044] Specifically, the lower end of the mounting base 2 extends into the interior of the workbench 1. A guide groove 33 for vertically guiding each set of lifting seats 31 is installed on the inner wall of the mounting base 2. A guide seat 34 is slidably installed inside the guide groove 33. The guide seat 34 is fixedly installed on the outer wall of the lifting seat 31.

[0045] When the lifting seat 31 moves up and down, it moves along the guide groove 33 via the guide seat 34, which can strictly limit the displacement of the lifting seat 31 in the horizontal direction (X-axis, Y-axis) and only retain the degree of freedom of movement in the vertical direction (Z-axis), thereby avoiding the lifting seat 31 from tilting or shifting due to uneven load or external disturbance.

[0046] Example 3:

[0047] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, a limit seat 21 is fixedly installed on the lower inner wall of the mounting base 2 below each set of lifting seats 31, and a position sensor 22 is installed on the limit seat 21.

[0049] When the lifting seats 31 are disconnected, the lifting seats 31 will slide downwards under the influence of gravity to the limit seats 21. The limit seats 21 restrict the position of the lifting seats 31 and limit the multiple limit seats 21 to the same horizontal plane. The position sensor 22 installed on the limit seats 21 can detect the position data of the lifting seats 31 in real time, thereby ensuring whether the lifting seats 31 have slid down into place.

[0050] Specifically, the upper surface of the worktable 1 is provided with an upper mold assembly 4.

[0051] Specifically, the upper mold assembly 4 includes a housing 41 mounted on the upper surface of the worktable 1. Inside the housing 41, above the split mold assembly 3, an upper hydraulic cylinder 42 is mounted, and the output end of the upper hydraulic cylinder 42 is mounted on the upper mold 43.

[0052] In use, the upper hydraulic cylinder 42 can cause the upper mold 43 to move and cooperate with the lower mold 32 to complete the stamping and bending work.

[0053] Specifically, a displacement sensor 35 is installed at the corner of the upper surface of the lower die 32. The displacement sensor 35 is a laser displacement sensor with an accuracy of +0.005mm. The installation positions are equidistantly distributed along the cutting edges of the lower die 32 and the upper die 43 to monitor the wear and installation offset (and surface damage) of the die in real time. The distance sensor 35 is connected to the PLC controller of the bending machine through an RS485 interface to complete data transmission. When the wear exceeds 0.05mm, the controller triggers an alarm and suspends the operation, realizing the intelligent detection function.

[0054] In use, activating the electric actuator 313 drives the support member 312 and the locking tooth 315 to move, causing the support member 312 and the locking tooth 315 to move from the lifting seats 31 on both sides to the middle lifting seat 31, so that the support member 312 and the locking tooth 315 are inserted into the inner groove 311 and tooth groove 314 of the middle lifting seat 31. This completes the work of connecting the components, so that the lifting seat 31 and the middle lifting seat 31 form a whole with synchronous lifting and lowering movement. With the power of the lower hydraulic cylinder 5, the various parts of the load-bearing plate are punched and bent in sequence to ensure that the bending parameters of the load-bearing plate meet the standards and to avoid the problem of the lower hydraulic cylinder 5 increasing its own load due to the overall punching.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
