Description

Technical Field

[0001] The invention belongs to the technical field of shearing equipment, and in particular relates to a high-precision CNC shearing machine that can quickly locate and is suitable for shearing long sizes. Background Art

[0002] The CNC hydraulic shearing machine consists of a machine body, a hydraulic system, a CNC device, etc. The hydraulic system provides power and the CNC device provides precise control. It can accurately shear metal plates according to set sizes. It has the characteristics of high precision and good degree of automation. It is widely used in sheet metal processing, machinery manufacturing and other industries to improve production efficiency and quality.

[0003] In the operation process of the CNC shearing machine, the feeding structure plays a vital role. Its feeding accuracy directly determines the shearing accuracy. Taking the automatic feeding device of a CNC shearing machine disclosed in patent announcement number CN117840507A as an example, it can improve the feeding efficiency to a certain extent. However, there are many challenges in the processing of thin metal plates in practical applications. In order to facilitate transportation and storage, thin metal plates are usually curled. When they need to be fed into a CNC shearing machine for long-size shearing processing, due to the characteristics of the thin metal plates themselves, such as soft texture, easy bending, easy deformation, and burrs on the edges, traditional feeding methods, such as roller conveying and push plate pushing, have obvious limitations. During roller conveying, the thin plate may slip due to uneven friction between the roller and the roller. When pushing with a push plate, the thin plate may be easy to deform, have burrs on the edges, and other characteristics, resulting in poor pushing distance accuracy. These are very likely to cause inaccurate feeding length, which will seriously affect the shearing accuracy of the CNC shearing machine. Summary of the invention

[0030] The operating principle of the present invention is described as follows: Taking a sheet with a thickness of 2 mm as an example, the metal sheet to be sheared passes through the feed frame 5 and the processing area 3 (refer to Figure 4 , the dotted line part is the plate, and the dotted line arrow is the feeding direction), so that the end of the plate is flush with the discharge end of the processing area 3. At this time, the distance between the end of the plate and the center of the shear groove 44 is 0.5 meters, and the distance between the center of the shear groove 44 and the middle between the two clamping plates 72 is 1 meter. After the end of the plate is aligned, start the control cabinet 2; After the control cabinet 2 is started, the control cabinet 2 will control the clamping electric hydraulic cylinder 91 to work for a timed 2 seconds, and the clamping electric hydraulic cylinder 91 will drive the clamping plate 92 to move down. After the timing is over, the clamping plate 92 will clamp and fix the plate. Then, at the same time, the control cabinet 2 controls the oblique electric hydraulic cylinder 81 to work for a timed 3 seconds. After the timing is over, the roller walls of the two reverse push roller assemblies 83 are against the end surface of the plate. Then, the control cabinet 2 controls the pushing electric hydraulic cylinder 62 to work for a timed 6 seconds. The pushing electric hydraulic cylinder 62 will drive the feed frame 5 to move 1 meter away from the machine body 1 through the connecting block 63. During the movement, due to the clamping and pushing action of the two reverse push roller assemblies 83, the deformed position of the plate is straightened, and the part of the plate located between the reverse push roller assembly 83 and the clamping plate 92 remains in a taut state. After the timing work is over, the control cabinet 2 controls the two clamping electric hydraulic cylinders 71 to work for a timed 2 seconds. At this time, the two clamping plates 72 will clamp and fix the plate. After the timing work of the holding electric hydraulic cylinder 71 is finished, the control cabinet 2 will first control the two clamping electric hydraulic cylinders 91 to perform a timing return action, and the control cabinet 2 will simultaneously control the two pushing electric hydraulic cylinders 62 to perform a timing return action of 6 seconds. Since the clamping plate 72 clamps and fixes the plate, when the pushing electric hydraulic cylinder 62 returns, the two clamping plates 72 will drag the plate back synchronously, so that the plate can be dragged to move 1 meter. After the pushing electric hydraulic cylinder 62 returns and resets, the control cabinet 2 controls the clamping electric hydraulic cylinder 91 to work regularly again, and then controls the clamping electric hydraulic cylinder 71 to return and reset, and then repeats the above steps to make the plate continue to move back. Since the plate is straightened and flattened by the reverse flattening roller assembly 83 each time, the distance of each plate return is 1 meter, so the number of times the plate returns can be controlled according to the required shearing length (when the required length is not an integer, the control cabinet 2 can be pre-set to make the last push electric hydraulic cylinder 62 return an appropriate distance to ensure that the required length meets the requirements); After the plate is moved back, the control cabinet 2 controls the two forward electric hydraulic cylinders 101 to work for a timed period of 2 seconds. The forward electric hydraulic cylinder 101 drives the forward push roller assembly 103 to move horizontally along the plate feeding direction through the moving plate 102. Under the moving pressure of the forward push roller assembly 103, the plate at the shearing groove 44 will also be straightened and tightened, that is, to ensure that the portion of the plate between the forward push roller assembly 103 and the clamping plate 72 remains in a taut state, thereby further preventing the bending of the plate from affecting the shearing accuracy. When the forward electric hydraulic cylinder 101 works at a scheduled time, the control cabinet 2 controls the shearing electric hydraulic cylinder 41 to work at a scheduled time. The shearing electric hydraulic cylinder 41 can drive the shearing knife 43 to move downward, thereby shearing the plate. After the shearing is completed, the shearing electric hydraulic cylinder 41 moves back and resets, and then the above steps can be repeated to continue the shearing action of the next plate. After the control cabinet 2 is started, the control cabinet 2 will control the negative pressure suction pump 114 to work. The negative pressure suction pump 114 can suck in external air and transport the air to the inside of the frame plate 135 through the air supply hose 137. Then the airflow enters the two hollow bars 133 through each connecting hose 136, and finally is sprayed out through each oblique nozzle 134. The airflow sprayed by the oblique nozzle 134 is blown to the surface of the plate. Under the action of the airflow, impurities on the surface of the plate will be removed, thereby reducing the impact of impurities on the shearing quality of the plate by the shearing knife 43, and can also avoid scratches on the surface of the plate due to impurities to a certain extent. Secondly, when the control cabinet 2 is started, the control cabinet 2 will also control the light source 121 to work, and connect the connection circuit with the photoelectric switch 122. The light emitted by the light source 121 is irradiated to the photoelectric switch 122 through the stainless steel filter 115. The photoelectric switch 122 can convert the optical signal into an electrical signal. When the blade of the shearing knife 43 is sharp, the shearing knife 43 cuts the plate more smoothly and wears less. As the shearing knife 43 works, the blade of the shearing knife 43 becomes more and more blunt. When the shearing knife 43 is shearing the plate, the friction between the shearing knife 43 and the cutting surface of the plate is As the friction becomes greater, more debris will be generated. Therefore, when the shear knife 43 is excessively worn, more debris will fall into the shear groove 44. At this time, more debris will enter the collection box 112 with the airflow, and the debris will block part of the light irradiated to the photoelectric switch 122. Therefore, the light received by the photoelectric switch 122 will become weaker, resulting in insufficient light received by the photoelectric switch 122, and then causing the electrical signal fed back to the control cabinet 2 to be disconnected. At this time, the control cabinet 2 will remind personnel to check the shear knife 43 through its own voice module.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
