AI Technical Summary
In existing shearing machines, when cutting high-requirement car wash exterior panels, the shearing burrs face downwards, which can easily lead to stacking scratches, resulting in low safety and flexibility.
By designing a downward-cutting flying pendulum shearing machine, an eccentric wheel, a drive shaft, and an up-and-down rotating mechanism are adopted. Combined with a transmission gear and a servo reducer, the reciprocating rotation of the up-and-down rotating mechanism is realized. The combination of an upper straight blade and a lower V-shaped blade ensures that the burrs face upwards, and a piano key-type transition plate is set between the blades to prevent scratches.
This design allows for upward shearing of burrs, preventing scratches from stacking and improving the flexibility and safety of shearing, while ensuring precise and controllable shearing.

Moreover, the shearing method of swing shears, both domestically and internationally, is basically top-cutting. In the specification of a shearing machine (publication number CN204221859U), it is mentioned that "the base and the cutting table cooperate with each other, a positioning device is connected to the base, the positioning device includes a positioning slide rod, a slide rail is provided on the base to cooperate with the positioning slide rod, a positioning clamp is connected to the positioning slide rod, and the positioning clamp is in contact with the surface of the base." However, the shearing burrs in the prior art face downwards, which can lead to stacking scratches on high-requirement car wash exterior panels, making it neither safe nor flexible and practical. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, a downward-cutting flying shearing machine is provided to solve the problems of downward shearing burrs in existing technologies, which tend to cause stacking scratches on high-requirement car wash outer panels, and are not safe, flexible and practical.
[0004] To achieve the above objectives, a downward-cutting flying shearing machine is provided, comprising an eccentric wheel, a drive shaft, and an up-and-down rotating mechanism. The up-and-down rotating mechanism has a drive shaft installed at both its upper and lower parts, and an eccentric wheel installed at both its left and right ends. A mounting frame is provided in the middle of the up-and-down rotating mechanism, with an upper blade assembly installed in the upper part of the mounting frame and a lower blade assembly installed in the lower part of the mounting frame. The upper blade assembly and the lower blade assembly are arranged opposite each other, and a piano key-type transition plate is provided between the upper blade assembly and the lower blade assembly.
[0005] Furthermore, the centers of the drive shaft and the up-and-down rotating mechanism are both located on the same axis, and the up-and-down rotating mechanism rotates in one direction via the drive shaft.
[0006] Furthermore, servo reducers are provided at both the front and rear ends of the drive shaft, and transmission gears are installed on the servo reducers. The up-and-down rotation mechanism reciprocates through the transmission gears and servo reducers.
[0007] Furthermore, the upper part of the upper blade assembly is provided with a straight blade, and the upper part of the lower blade assembly is equipped with a V-shaped blade, and the material feeding direction moves from the front to the rear of the upper blade assembly and the lower blade assembly.
[0008] Furthermore, the lower end face of the upper blade assembly is flat on both sides, and the upper end face of the lower blade assembly is provided with an arc-shaped notch, and the upper end face of the lower blade assembly is inclined with the front lower than the back.
[0009] Furthermore, the upper part of the piano key-type transition plate is equipped with multiple sets of anti-scratch universal balls, and a spring plate is provided between the anti-scratch universal balls and the adjacent set of anti-scratch universal balls.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. The up-and-down rotating mechanism in this utility model can rotate unidirectionally via a transmission shaft to achieve the single task of shearing; while the up-and-down rotating mechanism can achieve reciprocating up-and-down rotation via transmission gears and servo reducers to complete the oscillation of the blade. By adjusting the blade mounting structure, downward cutting shearing with burrs facing upward is achieved, making it more flexible and practical.
[0012] 2. The upper blade assembly is set so that the straight blade is at the top and in front, and the lower blade assembly is set so that the V-shaped blade is at the bottom and behind. Only in this way can the burrs face upwards during cutting.
[0013] 3. The structure of the lower blade of this utility model adopts an upper straight blade and a lower V-shaped blade, which meets the technical requirement that the burrs on the steel plate face upward after shearing, making it more convenient and practical.
[0014] 4. This utility model features a piano key-style transition plate between the upper and lower blade components, which can be stacked under the piano keys. Raising the plate head prevents interference with shearing and feeding, ensuring precise and controllable adjustment. Attached Figure Description

[0025] In this embodiment, the centers of the drive shaft 2 and the up-and-down rotating mechanism 3 are located on the same axis, and the up-and-down rotating mechanism 3 rotates in one direction through the drive shaft 2; both the front and rear parts of the drive shaft 2 are equipped with servo reducers 7, and the servo reducers 7 are equipped with transmission gears 6, and the up-and-down rotating mechanism 3 reciprocates through the transmission gears 6 and the servo reducers 7.

By adjusting the blade mounting structure, downward cutting shearing with burrs facing upward is achieved, making it more flexible and practical.
[0027] In this embodiment, a straight blade 40 is provided on the upper part of the upper blade assembly 4, and a V-shaped blade 50 is installed on the upper part of the lower blade assembly 5.
