[0028] like Figure 3 and 4 As shown, this embodiment discloses a rotary punching device suitable for trapezoidal sheets, which structure includes a working base plate 1 with a working notch 2, a rotating mother seat 3 installed below the working base plate 1 and corresponding to the working notch 2, a rotating punching assembly 4 installed above the working base plate 1 and corresponding to the rotating mother seat 3, and a control unit 14 for controlling the rotating mother seat 3 and the rotating punching assembly 4 to work synchronously. One end of the working base plate 1 is a feeding end 5, and the other end is a discharging end 6.

[0029] The rotary base 3 includes a base 7, a lifting turntable 8 rotatably mounted on the base 7 via a rotating shaft, a driving motor 15 installed in the base 7 to drive the lifting turntable 8 to rotate, and a cylinder 16 installed in the base 7 to drive the lifting turntable 8 to rise and fall. A female groove is provided on the lifting turntable 8, and the female groove is relatively matched with the cutter 11 on the rotary punching assembly 4. The rotary punching assembly 4 includes a movable plate 9, a rotary cutter disc 10 mounted on the movable plate 9 via a rotating shaft, and a cutter 11 mounted on the rotary cutter disc 10. The driving unit 12 is installed on the movable plate 9 to drive the rotary cutter disc 10 to reciprocate and ensure that the cutter 11 can cut accurately.

[0030] The working base plate 1 is designed to provide a stable platform with a working notch 2 to facilitate the feeding and unloading of the blanks. The material of the working base plate 1 can be selected from high-strength steel or aluminum alloy to ensure that it is strong and durable and can withstand high-frequency operations. The width of the working notch 2 of the working base plate 1 is adjustable so that it can adapt to trapezoidal blanks of different sizes. This adjustable design can be achieved through simple mechanical adjustment.

[0031] The rotating base 3 is the key part of the device. Its base 7 is fixedly installed under the working base plate 1. The lifting turntable 8 connected by the rotating shaft can move up and down under the drive of the cylinder 16 and rotate under the action of the driving motor 15. This design enables the cutter 11 to punch twice through a single rotation to complete the precise cutting of the trapezoidal sheet. The material of the lifting turntable 8 is generally wear-resistant steel to increase its service life and reliability.

[0032] The movable plate 9 in the rotary punching assembly 4 is fixed on the working base plate 1 through a bracket, and the rotary cutter disc 10 is connected to the movable plate 9 through a rotating shaft, and can realize reciprocating rotation under the action of the driving unit 12. The cutter 11 is installed on the rotary cutter disc 10 and cooperates with the mother groove to ensure the accuracy of cutting. The material of the cutter 11 is usually selected from high-speed steel or hard alloy to ensure its sharpness and durability.

[0033] The driving unit 12 is composed of two driving air rods 17. The two driving air rods 17 are relatively arranged at the center of the rotating cutter head 10. The two air rods realize reciprocating motion through compressed air to drive the rotating cutter head 10 to perform precise angle adjustment.

[0034] The control unit 14 is responsible for coordinating the synchronous operation of the rotating mother seat 3 and the rotating punching assembly 4. The core of the control unit 14 is a programmable logic controller (PLC), which includes a central processing unit (CPU), an input / output (I / O) module, a power module and a communication module. The PLC is connected to various sensors, drivers and actuators through the I / O module to collect and process signals in real time. PLC programming uses ladder diagrams or structured text languages ​​to control according to the set logic.

[0035] The control unit 14 also includes a human-machine interface (HMI) for operators to set parameters and monitor status. The HMI display screen displays the operating status, process parameters and alarm information of the equipment through a graphical interface, and the operator can perform operations such as starting, stopping, and adjusting parameters through the touch screen.

[0036] It should be understood that the specific structure, composition, and working principle of the control unit 14 are all prior art, and for those skilled in the art, these principles and circuit structures are common technical knowledge. In addition, there are a large number of mature control unit products on the market that can be directly purchased and realize the above functions, such as PLC control host, etc., so no more detailed description is given here.

[0037] As a more detailed description of this embodiment, the optical detection component 13 is installed above the working base plate 1 through a fixed bracket, and includes an illumination light source and an industrial camera. The illumination light source provides uniform illumination, and the industrial camera collects image information of the discharged parts. The image information is transmitted to the control unit 14 through the communication module, and the PLC processes and analyzes the image to determine the quality and position of the discharged parts, ensuring the accuracy and consistency of each trapezoidal sheet.

[0038] In actual use, the trapezoidal sheet enters from the feed end 5 of the working substrate 1 and enters the cutting area through the working notch 2. The lifting turntable 8 moves upward and, after being flush with the working substrate 1, cooperates with the cutter 11 to complete the first punching process. At the same time, the rotating mother seat 3 and the rotating punching assembly 4 rotate to adjust the angle at the same time, and then the lifting turntable 8 moves upward again and cooperates with the cutter 11 to complete the second punching process. This process is repeated to achieve continuous punching. The entire process is monitored and adjusted in real time by the control unit 14 to ensure the accuracy and efficiency of cutting.

[0039] Traditional punching devices usually require two cutting tools to be installed on the same die to complete the processing of trapezoidal blanks. This method has obvious deficiencies in flexibility and adjustment. Specifically, when the size and angle of the trapezoidal blanks change, the traditional device needs to remake the die or make major adjustments, which not only increases the debugging and downtime of the equipment, but also leads to increased production costs.

[0040] In contrast, the rotary punching device in this embodiment has significant flexibility and versatility in design. Through the adjustable width of the working notch 2 of the working base plate 1 and the synchronous rotation adjustment of the rotary base 3 and the rotary punching assembly 4, the device can quickly adapt to the processing requirements of trapezoidal sheets of different sizes and angles. There is no need to frequently change molds and make complex adjustments, which greatly improves production efficiency and reduces production costs.

[0041] For example, in an actual use scenario, a factory needs to quickly switch from producing a trapezoidal sheet of a specific size to a trapezoidal sheet of another size and angle. Traditional punching devices may take hours or even days to redesign and adjust the mold, but the device of this embodiment can be adjusted and put into production in a few minutes through simple adjustments and program settings. This rapid response capability enables the factory to respond to changes in market demand more flexibly and improve the efficiency and competitiveness of the overall production line.

[0042] Through the detailed description of this embodiment, it can be seen that the rotary punching device has the advantages of simple structure, convenient operation, high cutting accuracy, strong adaptability, etc. Especially in the processing of trapezoidal sheets, the single-blade rotary punching twice overcomes the problems of complex molds, inconvenient adjustment, poor flexibility, etc. in the prior art, greatly improving production efficiency and product quality. Combined with specific usage scenarios, the device can be widely used in the processing of various trapezoidal sheets, significantly improving the automation level and processing capacity of the production line.

[0043] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
