Description

[0002] Existing sheet metal cutting methods, due to the wide variation in product thickness, are unable to achieve optimal results for some specialized products. They are also time-consuming and labor-intensive, resulting in low yield rates, which directly impacts final product performance. Furthermore, the cutting process requires multiple machine stops for feeding and unloading, resulting in low processing efficiency.

[0003] At the same time, the traditional guillotine structure requires the upper and lower blades to fit tightly together, which places very high demands on the processing accuracy and installation accuracy of the blades. For example, if there is a 0.1mm gap between the blades, then 0.1mm material may not be cut through.

[0042] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0043] like Figures 1 to 8 A continuous cutting device includes a pair of bases, including a left base 1 and a right base 2. A cutting processing area is formed between the left base 1 and the right base 2. The difference lies in that: in order to achieve continuous feeding of the material to be processed, an active roller 3 is installed in the cutting processing area. The active roller 3 is located on one side of the base and is connected to a drive device. A driven roller 4 is provided at the upper end of the active roller 3 in the cutting processing area. Auxiliary drive devices are provided on both sides of the driven roller 4, and the auxiliary drive devices are connected to the corresponding left base 1 and right base 2. Combined with actual use, under the action of the driven roller cylinder 20, the driven roller 4 will be subjected to a downward pressure stress, which will reduce the distance between the driven roller 4 and the active roller 3 and can clamp the material. Therefore, when the active roller 3 rotates under the control of the drive device, the driven roller 4 can also achieve appropriate follow-up rotation to ensure smooth feeding of the material. From the perspective of the material feeding process, if the driven roller 4 is not used to perform the corresponding coordinated movement, the active roller 3 cannot achieve smooth material feeding under the control of the driving device, and idling often occurs. Taking into account the need for continuous cutting, the present invention provides a scissor device at the discharge end of the active roller 3 in the cutting processing area. Specifically, the scissor device includes an upper scissor blade 5, and the front end of the upper scissor blade 5 is movably connected to the lower scissor blade 7 through the scissor end shaft 6. An auxiliary spring is provided on the scissor end shaft 6 to adjust the pressing force at the contact point of the front ends of the upper scissor blade 5 and the lower scissor blade 7, so as to facilitate the adjustment of the friction force of the opening and closing of the scissors.

[0044] Furthermore, a material guide plate 8 is positioned immediately behind and adjacent to the upper scissor blade 5. This plate features a slit for the material being cut. This slit allows the material to pass through the scissor blades, preventing it from falling out after cutting. Furthermore, to facilitate shear control, an upper scissor shaft assembly is attached to the tail end of the upper scissor blade 5, while a lower scissor shaft assembly is attached to the tail end of the lower scissor blade 7. These two scissor shaft assemblies are connected via a cylinder assembly 9.

[0045] In combination with a preferred embodiment of the present invention, the upper scissor shaft assembly used includes a cylinder seat 10 connected to the left base 1. In order to facilitate the subsequent cylinder assembly 9 to smoothly drive the movement of the lower scissor blade 7, a cylinder rotating shaft 11 is provided on the cylinder seat 10. At the same time, the present invention is provided with a cylinder bearing 12 at the front end of the cylinder rotating shaft 11, and the cylinder bearing 12 is externally connected to a cylinder mounting plate 13. Specifically, the cylinder mounting plate 13 is pressed and fixed to the front end of the cylinder rotating shaft 11 through the limitation of the cylinder bearing 12 and the locking nut 14, and can rotate around the cylinder rotating shaft 11. In addition, in order to achieve smooth working drive, the cylinder assembly 9 is installed on the cylinder mounting plate 13, so that the cylinder assembly 9 can rotate around the cylinder rotating shaft 11.

[0046] Combine Figure 5 Furthermore, the lower scissor shaft assembly includes a floating joint 15, the fixed end of which is connected to the tail end of the lower scissor blade 7, and the floating end of which is connected to the adjustment mechanism 16. The adjustment mechanism 16 is mounted with a lower scissor seat 17, and the cylinder assembly 9 is connected to the lower scissor seat 17.

[0047] Combine Figures 6 to 8 As can be seen, the lower scissor blade 7 is connected to the fixed end of the floating joint 15. Simultaneously, the adjustment mechanism 16 includes an optical shaft 23 for connection to the floating end of the floating joint 15. One end of the optical shaft 23 is connected to the end sleeve 25, and the optical shaft 23 can slide within the inner hole of the end sleeve 25, forming a clearance fit with a clearance margin of 0.05-0.1mm. A spring 22 is provided on the outer sleeve of the optical shaft 23. One side of the spring 22 rests against one end face of the floating joint 15, and the other side of the spring 22 rests against the side face of the end sleeve 25. The end sleeve 25 is connected to the internally threaded through hole of the lower scissor seat 17 via an outer thread 24. A locknut 18 is threadedly connected to the end sleeve 25. Furthermore, in view of the actual assembly, the optical shaft 23 is also connected to the floating joint 15 of the lower scissor shaft assembly.

[0048] During implementation, with the dotted line serving as the demarcation line for blade deformation, the floating joint 15 is subjected to a leftward force from the spring 22 in the adjustment mechanism 16, which is then transmitted to the lower scissor blade 7. Consequently, the lower scissor blade 7 is subjected to a leftward force along the axis 21. The magnitude of this force can be adjusted by the adjustment mechanism 16. Under this controllable force, the lower scissor blade 7, made of spring steel, undergoes a leftward torsional deformation, the amount of which is typically controlled to be within 2 mm. After torsional deformation occurs, due to the ±5° deflection between the floating end and the fixed end of the floating joint 15, the fixed and floating ends become misaligned, thereby absorbing the undue stress generated by the torsional deformation and enhancing the stability of the entire scissor assembly. If this deflection were absent, the torque from this abnormal torsional deformation would be transmitted to the cylinder assembly, destabilizing the entire assembly. Thus, the controllable deformation of the lower scissor blade 7 ensures that the lower scissor blade 7 and the cutout of the upper scissor blade 5 are always in contact.

[0049] Furthermore, by sliding the optical axis 23 in the inner hole of the end sleeve 25, the adjustment mechanism 16 can not only generate a leftward pressure, but also expand and contract along the axis 21, and the maximum expansion and contraction amount is about 4mm. Relying on this elastic expansion and contraction method, the force of the adjustment mechanism 16 on the lower scissor blade 7 can be adjusted. At the same time, the outer ring thread 24 of the end sleeve 25 and the inner hole thread of the lower scissor seat 17 cooperate. By rotating the end sleeve 25 clockwise, the spring 22 can be compressed to increase the pressure, and by rotating the end sleeve 25 counterclockwise, the spring 22 can be relaxed to reduce the pressure. In addition, the distance that the end sleeve 25 is screwed in is controllable. The greater the screwing distance, the greater the elastic force generated by the spring 22, and the greater the deformation of the lower scissor blade 7. The less the screwing distance, the less deformation. Finally, the presence of the anti-loosening nut 18 can achieve double thread locking after satisfying the corresponding tightness adjustment.

[0050] Furthermore, the driving device used in the present invention is a servo motor 19, which is connected to one side of the active roller 3 through a coupling. At the same time, the auxiliary driving device used is a driven driving cylinder 20.

[0051] The working principle of the present invention is as follows:

[0052] The feeding is completed by the servo motor 19. The main control system used in conjunction with the present invention sends a signal to move the cylinder assembly 9, which drives the lower scissor blade 7 and the upper scissor blade 5 to close to complete the cutting.

[0053] At every moment of cutting, since the lower scissor blade 7 is in a state of being bent to the left, the lower scissor blade 7 and the upper scissor blade 5 are constantly fitted together, and each fitting point is in a tightly fitted state without any gaps, thus satisfying the reliable cutting of ultra-thin materials.

[0054] Specifically, as the lower scissor blade 7 fits upward with the upper scissor blade 5, the lower scissor blade 7 gradually changes from a bent state to an extended state. At the same time, this deformation displacement will be directly transmitted to the end of the lower scissor blade 7 and further to the floating joint 15. In this case, if left untreated, this deformation displacement will eventually be transmitted to the cylinder assembly 9, causing the cylinder assembly 9 to be subjected to a strong force in a direction other than its own expansion and contraction direction, which will damage the cylinder assembly 9. Since the adjustment mechanism 16 itself can expand and contract, this part of the displacement will be absorbed by the adjustment mechanism 16 after passing through the floating joint 15, thereby ensuring the normal operation of the cylinder assembly 9. Furthermore, it can be ensured that there is no gap at the fitting point of the lower scissor blade 7 and the upper scissor blade 5. As a result, as the lower scissor blade 7 and the upper scissor blade 5 fit together, the material is fed and sheared at the same time.

[0055] It can be seen from the above textual description and the accompanying drawings that the present invention has the following advantages:

[0056] 1. Compared with the traditional guillotine structure, the scissors structure can cut thinner and softer materials.

[0057] 2. In comparison, the scissors structure has slightly lower processing accuracy for the blade, and basically has no requirements for installation accuracy. Moreover, the scissors structure has no gaps at each fitting point, which can meet the precise cutting requirements in the above situation.

[0058] 3. It is equipped with an independent adjustment mechanism, which can adjust the cutting force to suit the different materials being cut. For soft materials, a smaller force can be used, while for hard materials, a slightly larger force can be used. Compared with the guillotine mechanism, it is more practical.
