[0019] Preferably, the method comprises the following steps:

[0020] S1. Preparation: First, you need to determine the specific requirements for shearing, including the length, width, angle and other parameters of the shearing. According to these requirements, select the appropriate shearing machine and tools to ensure that the equipment is in good working condition. At the same time, check the quality and specifications of the metal material to ensure that it meets the shearing requirements;

[0021] S2. Material positioning and fixing: Place the metal material on the working table of the shearing machine and fix it with a clamp or positioning device to ensure that the material will not move or deform during the shearing process to ensure shearing accuracy and safety;

[0022] S3. Adjust the shearing parameters. According to the type, thickness and shearing requirements of the metal material, adjust the shearing machine's blade gap, shearing speed and pressure and other parameters. The adjustment of these parameters has an important impact on the shearing quality and efficiency.

[0023] S4. Start shearing, start the shearing machine, and let the blade shear the metal material according to the preset parameters. During the shearing process, keep the equipment running stably, pay attention to the shearing situation, and adjust the parameters in time to deal with possible problems;

[0024] S5. Quality inspection: After shearing is completed, the quality of the sheared metal material is inspected to check whether the sheared surface is flat and smooth, and whether there are defects such as cracks and burrs. For unqualified sheared parts, secondary shearing or repair is required;

[0025] S6. Follow-up processing: Carry out follow-up processing on the sheared metal materials as needed, such as grinding, cleaning, rust prevention, etc. At the same time, tidy up the shearing site, clean up waste materials and tools, and keep the working environment clean.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) A positioning seat is slidably installed on the top of the mounting plate, and then an extrusion rod is connected to the top of the positioning seat through a movable shaft, and a swing seat is connected to the top of the extrusion rod through a movable shaft. The positioning seat connected to the movable shaft at the bottom of the extrusion rod can be driven to move while the swing seat descends to shear. Then, the reset spring will automatically pop out the arc block into a row of arc grooves through its own elastic force, and then the movable positioning seat can be slid and limited. After the swing seat finishes shearing and resets and flips, the arc block will drive the transmission conveyor belt to move through the arc groove, and then the metal parts can be driven to automatically extend and discharge the materials, which is more time-saving and labor-saving.

[0028] (2) Furthermore, a moving rod is slidably installed through a slot on the inner side of the top of the positioning seat, and then an extrusion rod is connected to the top of the moving rod through a movable shaft. After the extrusion rod is extruded and lowered, the extrusion moving rod drives the arc-shaped clamping plate to extrude and limit the metal part through the anti-slip pad, thereby avoiding the phenomenon of misalignment and displacement of the sheared metal part during shearing, thereby improving the shearing efficiency of the shearing machine. After the shearing is completed, the reset spring will elastically reset the position of the moving rod after the extrusion and lowering through its own elastic force, thereby separating the metal part from the positioning seat, and then the metal part can be conveniently moved and fed inside the positioning seat;

[0029] (3) A movable frame is installed by sliding through grooves at both ends of the cleaning frame, and arc-shaped connecting plates are screwed on the inner ends of the two movable frames, and cleaning brushes are arranged on the inner sides of the two connecting plates. Then, the inner sides of the two cleaning brushes are fitted and connected to the outer wall of the metal part. The two cleaning brushes can be used to clean and wipe the dust and impurities stuck on the surface of the metal part while the metal part is moving and feeding, so as to avoid the dust and impurities sticking to the surface of the metal part and affecting the shearing process of the tool holder, thereby improving the service life of the tool holder;

[0030] (4) Furthermore, when the knife seat is flipped and sheared, the two torsion springs will elastically reset the two transmission gears through their own elastic force, and then the two transmission gears will drive the two moving frames to move through the two racks. At this time, the moving frames can drive the two connecting plates to separate from the metal parts, and then the shearing machine can conveniently shear the metal parts. When the shearing is completed and flipped and reset, the two pull ropes will be driven to pull the two transmission gears to rotate at the same time, and then the two connecting plates can be driven to drive the two cleaning brushes to move and clean the metal parts, thereby improving the shearing efficiency of the shearing machine;

[0031] (5) The knife holder is installed by slotting the inner side of the bottom of the swing seat. When the knife holder needs to be disassembled and replaced after long-term shearing and wear, the limit rod is manually pressed to retract and move, so that the limit rod is retracted to the inside of the knife holder. At this time, the swing seat can be separated from the knife holder, and then the elastic force of the extrusion spring can be used to elastically reset the position of the limit rod after pressing, so that the knife holder can be quickly disassembled, assembled and replaced, which is more practical and saves time and effort.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention provides the following technical solutions:

[0045] Embodiment 1, in order to solve the problem that the existing shearing machine cannot automatically feed and shear the metal part 6, discloses:

[0046] The fuselage 1 has a control box 2 screwed on the upper right side thereof, and the control box 2 is connected to an electric telescopic rod 3 through a wiring harness, and the electric telescopic rod 3 is rotatably mounted on the upper right side of the fuselage 1;

[0047] It also includes: a fuselage 1, a swing seat 4 is rotatably mounted on the upper right side thereof, a knife seat 5 is mounted on the inner side of the bottom of the swing seat 4, and a metal piece 6 is correspondingly mounted on the bottom of the knife seat 5, and the metal piece 6 is placed above the transmission conveyor belt 8, a fuselage 1, a mounting plate 7 is screwed on the upper side thereof, and a transmission conveyor belt 8 is arranged inside the mounting plate 7, and the upper side of the transmission conveyor belt 8 extends to the upper outer side of the mounting plate 7, and a cleaning frame 9 is screwed on the front side of the fuselage 1, and the internal slot of the cleaning frame 9 penetrates and is slidably connected with the mounting plate 7;

[0048] The mounting plate 7 has a limit seat 14 installed by screws on the upper left side thereof, and the internal slot of the limit seat 14 penetrates the metal part 6 which is slidably connected, and the right end of the metal part 6 penetrates the positioning seat 12 which is slidably connected, and at the same time, the top of the positioning seat 12 is connected to the extrusion rod 11 through a movable shaft, and the top of the extrusion rod 11 is connected to the swing seat 4 through a movable shaft, and the extrusion rod 11 is inclined.

[0049] The positioning seat 12 has a groove on the outer side of its bottom on which an arc block 16 is rotatably installed, and the arc block 16 is in an arc shape, and the bottom of the arc block 16 is connected with an arc groove, and a row of arc grooves are evenly spaced and arranged on the outer side of the transmission conveyor belt 8. The positioning seat 12 has a groove on the inner side of its bottom on which a return spring 17 is arranged, and the outer end of the return spring 17 is connected to the arc block 16.

[0050] like Figure 1-Figure 4As shown, when the shearing machine is shearing the metal part 6, the electric telescopic rod 3 will drive the knife seat 5 installed at the bottom of the swing seat 4 to flip and descend for shearing. At this time, the swing seat 4 will drive the extrusion rod 11 to move the position of the positioning seat 12 through the movable shaft, and then the reset spring 17 will use its own elastic force to pop out the arc block 16 into a row of arc grooves in sequence, and then the positioning seat 12 can be slidably limited to avoid the side sliding deviation of the positioning seat 12 during the later shearing process. When the shearing is completed and flipped and reset, the arc block 16 will drive the metal part 6 placed above the transmission conveyor belt 8 to move its position through the arc groove. At this time, the automatic feeding setting of the metal part 6 can be completed, avoiding the traditional shearing machine The complicated steps such as manual feeding are avoided, saving time and effort, and improving the shearing efficiency of the shearing machine.

[0051] Embodiment 2 is different from Embodiment 1 in that when the knife holder 5 performs shearing processing on the metal member 6, the metal member 6 can also be clamped and positioned to avoid the metal member 6 from being displaced and offset during the subsequent shearing processing.

[0052] The positioning seat 12 has a groove on the inner side of the top through which a moving rod 15 is slidably installed, and the top of the moving rod 15 is connected to the extrusion rod 11 through a movable shaft, and the bottom end of the moving rod 15 is connected to an arc clamping plate 18 through a screw, and the arc clamping plate 18 is in an arc shape, and the inner side of the arc clamping plate 18 is connected to the outer wall of the metal part 6 through an anti-slip pad 19, the moving rod 15 has a return spring 17 wound around the outer side of the top, and the outer end of the return spring 17 is connected to the inner wall of the positioning seat 12, and the fuselage 1 is coated with a metal fiber sound absorbing layer 13 on the outer side, and the metal fiber sound absorbing layer 13 is mainly made of metal fiber sound absorbing material.

[0053] like Figure 1-Figure 5 As shown, while the extrusion rod 11 is squeezing and moving the positioning seat 12, the extrusion rod 11 will squeeze the moving rod 15 through the movable shaft to move it downward, and then the moving rod 15 will drive the arc-shaped clamping plate 18 connected to the screw at its bottom to clamp and position the metal part 6 through the anti-slip pad 19, so as to avoid the metal part 6 from shaking and misalignment during the later shearing process, thereby improving the stability of the shearing machine. After the shearing process is completed and flipped, the reset spring 17 will elastically reset the position of the moving rod 15 after the squeezing and descending through its own elastic force. At this time, the metal part 6 can be separated from the arc-shaped clamping plate 18, and then the metal part 6 can be automatically fed later, which is more practical.

[0054] Embodiment 3 is different from Embodiment 2 in that dust and impurities adhering to the surface of the metal piece 6 can be automatically cleaned while the metal piece 6 is automatically fed.

[0055] The cleaning frame 9 has grooves at both ends thereof and is rotatably installed with a transmission gear 23 through a torsion spring 25, and the two transmission gears 23 are symmetrically arranged about the vertical center line of the cleaning frame 9, and the output ends of the two transmission gears 23 are connected with pull ropes 10, and the outer ends of the two pull ropes 10 are connected to the outer wall of the swing seat 4, the cleaning frame 9 has grooves at both ends thereof and is slidably installed with a moving frame 20, and the two moving frames 20 have the same structure, and the inner ends of the two moving frames 20 are screwed with connecting plates 21, and the inner ends of the two connecting plates 21 are fit-connected to the outer wall of the metal part 6 through a row of cleaning brushes 22, and the tops of the two moving frames 20 are meshed with two transmission gears 23 through racks 24.

[0056] like Figure 1-Figure 9 As shown, after the swing seat 4 drives the knife seat 5 to flip and reset, the two pull ropes 10 will simultaneously pull the two transmission gears 23 to rotate, and then the two transmission gears 23 will drive the two moving frames 20 to squeeze and move through the racks 24. At this time, the connecting plates 21 installed with screws at the inner ends of the two moving frames 20 will drive the two cleaning brushes 22 to squeeze and move in position, so that the two cleaning brushes 22 fit with the outer side walls of the metal parts 6. While the metal parts 6 are automatically fed, the two cleaning brushes 22 can be used to clean and wipe the dust and impurities stuck on the surface of the metal parts 6 to prevent dust and impurities from sticking to the surface of the metal parts 6 and affecting the subsequent shearing processing of the knife seat 5, thereby increasing the service life of the knife seat 5. Then, when the knife seat 5 shears the metal parts 6, the two torsion springs 25 will drive the two transmission gears 23 to rotate through their own elastic force, and then the two connecting plates 21 can be separated from the metal parts 6, which is more convenient for the stable shearing processing operation of the subsequent shearing machine.

[0057] The left side of the knife seat 5 is grooved with a compression spring 27 , and the left end of the compression spring 27 is connected to the limit rod 26 , and the left end of the limit rod 26 passes through the knife seat 5 and extends to the left side of the swing seat 4 .

At this time, the extrusion spring 27 will automatically pop out the limit rod 26 to the outer side of the bottom of the swing seat 4 through its own elastic force, and then the knife seat 5 can be quickly disassembled, replaced and processed, which is more practical and saves time and effort, thereby completing a series of tasks.

[0059] The steps include:

[0060] S1. Preparation: First, you need to determine the specific requirements for shearing, including the length, width, angle and other parameters of the shearing. According to these requirements, select the appropriate shearing machine and tools to ensure that the equipment is in good working condition. At the same time, check the quality and specifications of the metal material to ensure that it meets the shearing requirements;
