The bottom of the punching rod 32 The guide assembly 4 is also provided.

The punching component 3 punches the pressurized air duct back plate 1, but the guide component 4 needs to guide the air duct back plate 1 before punching. In the initial state, the punching cylinder 31 is first used to drive the guide. The positive assembly 4 moves downward, so that the guiding assembly 4 moves into the air duct back plate 1. After the air bag 41 of the guiding assembly 4 is inflated, the four walls of the air duct back plate 1 can be supported by the air bag 41, and then clamped The holding component 2 is performing pressure clamping, so that the pressure exerted by the holding component 2 on the air duct back plate 1 can be transferred to the guide component 4 to achieve a stress balance between the two, so that both sides of the air duct back plate 1 can be The clamping component 2 and the guide component 4 are pressurized, which can also avoid the horizontal deformation of the air duct back plate 1. After the clamping component 2 clamps the air duct back plate 1, the punching cylinder 31 continues to press down. The punching seat 33 can be driven down into the air duct back plate 1 , and the punching head 34 can be used to simultaneously punch both sides of the air duct back plate 1 , and then the air duct back plate 1 can be punched.

The punching rod 32 has a hollow interior and a movable rod 35 is slidably inserted into the inner bottom of the punching rod 32. A spring 36 is also fixedly connected between the top of the movable rod 35 and the movable rod 35, so The bottom of the punching seat 33 is flush with the bottom of the punching rod 32 .

After the subsequent clamping assembly 2 clamps the air duct back plate 1, the punching cylinder 31 continues to press down, which can drive the punch seat 33 to move downward into the air duct back plate 1, and use the punching head 34 to simultaneously press the air duct back plate 1 punching on both sides of the air duct back plate 1, and the guide assembly 4 is connected to the bottom of the movable rod 35, so when the punching seat 33 moves down, the movable rod 35 can be retracted to the punching rod 32 In this way, the punching head 34 can fully punch the air duct back plate 1 .

The guide assembly 4 includes a guide frame 40 and an air duct 42.

The air bag 41 has an L-shaped cross section and a horizontal portion of the air bag 41 is wrapped around the bottom of the guide frame 40 .

In the initial state, the punching cylinder 31 needs to be used to drive the guide frame 40 downward, so that the guide assembly 4 moves into the air duct back plate 1. After the air bag 41 is inflated with the help of the inflation pipe 42, the air bag 41 can be used to The four walls of the air duct back plate 1 are supported, and then the clamping assembly 2 performs pressure clamping, so that the pressure of the clamping assembly 2 on the air duct back plate 1 can be transmitted to the guide frame 40 to realize the stress between the two. Balance, so that both sides of the air duct back plate 1 can be pressurized by the clamping assembly 2 and the guide assembly 4, which can also avoid horizontal deformation of the air duct back plate 1 when the punching assembly 3 performs subsequent punching. , the punching cylinder 31 continues to drive the punching seat 33 to move downward, the movable rod 35 retracts into the punching rod 32, and the punching head 34 below the punching seat 33 gradually contacts the air duct back plate 1, but the punching seat 33 It will also come into contact with the guide frame 40. As the punch seat 33 pressurizes the guide frame 40, the bottom of the air bag 41 can be squeezed, and then the gas at the bottom is pressed to the side, thereby causing pressure on the back of the air duct. The side walls of the air duct back plate 1 are pressurized, but the outer wall of the air duct back plate 1 is provided with limiting plates 25, which are limited at both the inner and outer sides of the air duct back plate 1, thereby preventing the air duct back plate 1 from being compressed and deformed.

Working principle: In the initial state, the punching cylinder 31 needs to be used to drive the guide frame 40 downward, so that the guide assembly 4 moves into the air duct back plate 1. After the air bag 41 is inflated with the help of the inflation pipe 42, it can be The air bag 41 supports the four walls of the air duct back plate 1, and then the driving motor 26 drives the two-way screw 21 to rotate, which can drive the first movable base 22 and the second movable base 23 to move toward each other, thereby realizing the clamping of the air duct back plate 1 , the two movable bases 23 are symmetrically provided with limiting plates 25 on both sides, and the two movable bases 22 are symmetrically provided with jacks 24, and the limiting plates 25 are closely attached to the outer wall of the air duct backboard 1, so that they are clamped The pressure exerted by the component 2 on the air duct back plate 1 can be transferred to the guide frame 40 to achieve a stress balance between the two. In this way, both sides of the air duct back plate 1 can be pressurized by the clamping component 2 and the guide component 4. This can also avoid horizontal deformation of the air duct back plate 1. When the punching assembly 3 punches, the punching cylinder 31 continues to drive the punching seat 33 to move downward, and the movable rod 35 shrinks into the punching rod 32. The punching head 34 below the hole seat 33 gradually contacts the air duct back plate 1, but the punching seat 33 will also contact the guide frame 40. As the punch seat 33 pressurizes the guide frame 40, it can be The bottom of the air bag 41 is squeezed, thereby causing the gas at the bottom to be pressed to the side, thereby pressurizing the side walls of the air duct back plate 1. However, the outer wall of the air duct back plate 1 is provided with a limiting plate 25. The inner and outer sides of the duct back plate 1 are limited at the same time, which can prevent the air duct back plate 1 from being compressed and deformed. After the subsequent clamping assembly 2 clamps the air duct back plate 1, the punching cylinder 31 continues to press down, which can drive the punching The seat 33 is moved down into the air duct back plate 1, and the punching head 34 is used to punch both sides of the air duct back plate 1 at the same time, and then the air duct back plate 1 is punched. The guide assembly 4 is connected to the movable rod 35 Therefore, when the punching seat 33 moves down, the movable rod 35 can be retracted into the punching rod 32, so that the punching head 34 can fully punch the air duct back plate 1.
