[0028] In the embodiment, the positioning assembly includes a positioning block 1 for carrying the product to be punched and a pre-pressing mechanism for cooperating with the positioning block 1 to clamp the product to be punched. The positioning block 1 provides a stable support plane for the product to be punched. The surface shape and size of the positioning block 1 are usually designed according to the bottom contour of the product to be punched to ensure that the product can be placed flat and on the correct punching position reference.

[0029] Specifically, the pre-pressing mechanism includes a pre-pressing plate 2 for pressing the product to be punched and a first air cylinder 3 for driving the pre-pressing plate 2 to move relative to the positioning block 1. Before punching, the pre-pressing plate 2 applies a certain pressure to the product to be punched placed on the positioning block 1 through cooperation with the positioning block 1, tightly clamps the product, and prevents the product from being displaced or jumping during the punching process due to the action of the punching force. The first air cylinder 3 as the power source of the pre-pressing mechanism drives the pre-pressing plate 2 to move up and down or front and back relative to the positioning block 1 through the extension and retraction of the piston rod, and realizes the clamping and releasing actions of the product.

[0030] Specifically, the pre-pressing plate 2 is fixedly connected to the end of the piston rod of the first air cylinder 3, the positioning block 1 and the pre-pressing mechanism cooperate with each other in space, the positioning block 1 is fixedly installed on the workbench of the punching device, and the pre-pressing plate 2 can be accurately aligned in the vertical direction to effectively clamp the product to be punched.

[0031] In the embodiment, the punching device further comprises a base 4 for carrying the positioning assembly, the cutting assembly and the heating assembly. The positioning assembly further comprises a support 5 mounted on the base 4, and the pre-pressing plate 2 and the first cylinder 3 are mounted on the support 5. The support 5 is mounted on the base 4 to provide a vertical support structure for the pre-pressing mechanism composed of the pre-pressing plate 2 and the first cylinder 3. It enables the pre-pressing mechanism to work at a suitable height position to effectively clamp the product to be punched together with the positioning block 1.

[0032] In the embodiment, the cutting assembly comprises a cutter 6, a driving mechanism in driving connection with the cutter 6 for driving the cutter 6 to punch, and a fine adjustment mechanism 7 in driving connection with the cutter 6 for adjusting the posture of the cutter 6. The cutter 6 is a component in the cutting assembly that directly cuts the product to be punched. The fine adjustment mechanism 7 is used to accurately adjust the posture of the cutter 6 in a small range to prevent the posture of the cutter 6 from being deviated due to wear of the cutter 6 or slight changes in punching requirements during the punching process.

[0033] Specifically, the driving mechanism comprises a second cylinder 8 in driving connection with the cutter 6 for driving the cutter 6 to punch, and an electromagnetic valve 9 in driving connection with the second cylinder 8 for controlling the start of the second cylinder 8. The second cylinder 8 is a direct power component for driving the cutter 6. It converts the gas pressure energy into mechanical energy by acting on the piston inside to push the piston to move linearly. The second cylinder 8 is connected with the electromagnetic valve 9 through a gas pipe. The speed of the second cylinder 8 is controlled by adjusting the flow of the gas.

[0034] In the embodiment, the punching device further comprises a controller in communication connection with the electromagnetic valve 9 for controlling the start of the electromagnetic valve 9. The controller can control the start of the electromagnetic valve 9 according to a preset program or instruction, thereby indirectly controlling the punching action of the cutter 6.

[0035] Specifically, the controller is further in communication connection with the heating assembly. The punching device further comprises a base 10 on which a control panel 11 in communication connection with the controller is mounted. The controller is used to control the heating assembly according to the control instructions received by the control panel 11. The controller can receive and process the control instructions from the control panel 11 and convert them into specific control parameters for the heating assembly. The control panel 11 mounted on the base 10 is an interface for the operator to interact with the punching device. It provides an intuitive operation mode, enabling the operator to conveniently send control instructions to the controller. The control panel 11 can also be used to display the working state information of the punching device, including the current temperature of the heating assembly, the heating state (such as heating, reaching the set temperature, etc.), the working mode of the controller, etc.

It is arranged on the side of the cutter 6 and converts electric energy into heat energy to increase the temperature of the cutter 6. The temperature sensing wire 14 is arranged on the other side of the cutter 6 and is used for measuring the temperature of the cutter 6 in real time. It can accurately perceive the temperature change of the cutter 6 during the heating process and the punching process. The temperature sensing wire 14 sends the measured temperature data to the temperature controller 15 in the form of an electric signal to provide real-time temperature feedback for the control decision of the temperature controller 15. The temperature controller 15 can compare the actual temperature with the target temperature set by the operator on the control panel 11 and control the working state of the heating rod 13 according to the comparison result. If the actual temperature is lower than the target temperature, the temperature controller 15 will start or enhance the heating function of the heating rod 13; if the actual temperature is higher than the target temperature, the temperature controller 15 can take measures such as reducing the power of the heating rod 13 or stopping heating to make the temperature of the cutter 6 stable around the target temperature.
