Description

Technical Field

[0001] This invention relates to the field of distribution box manufacturing technology, and more specifically, to a shearing machine for distribution box manufacturing and its usage method. Background Technology

[0002] A distribution box is a power distribution device used to distribute low-voltage electrical energy. In a power system, it plays a crucial role in power distribution, circuit control, overload protection, and short-circuit / leakage protection. It is an indispensable power support facility in various building and industrial production scenarios. During the production and processing of distribution boxes, the metal sheets used to make the box body need to be cut to specific dimensions. Shearing machines are the core production equipment for this process. However, most conventional shearing machines on the market have problems with poor sheet positioning during cutting, leading to sheet displacement and insufficient dimensional accuracy, affecting the forming quality of the distribution box body. Furthermore, some shearing machines have poor cutting protection, and the metal shavings generated during cutting can easily fly, posing a potential threat to the safety of on-site operators. To address these shortcomings in existing technologies…

[0003] According to patent document CN120734410A, a shearing mechanism for a shearing machine, belonging to the field of shearing machine technology, includes a shearing cabinet and a pressure cylinder assembled at the inlet of the shearing cabinet. A shearing unit is installed on one side of the inner cavity of the shearing cabinet. The shearing unit includes a gap adjustment component slidably installed in the shearing cabinet. A moving blade is installed in the gap adjustment component through a mounting bracket. Through the shearing unit and the back gauge unit, the bending deformation of the steel strip during shearing is suppressed: the upper positioning component moves down with the moving blade in real time, applying dynamic clamping force to the plate in the shearing area. In conjunction with the pressure cylinder to fix the front end of the plate, it effectively offsets the local stress concentration caused by the uneven shearing force of the oblique blade, avoids bending of the thin plate during shearing, and achieves horizontal stability during the shearing process: the support component is kept horizontal by the inclined rod of the back gauge unit and moves down synchronously with the moving blade to ensure that the plate in the shearing area is horizontal throughout the process, reducing warping caused by the inclined shearing force.

[0004] In the production process of electrical distribution boxes, several sheet materials are typically manufactured and then spliced ​​and welded together to form a complete distribution box. During production, these sheet materials usually require cutting rollers. The traditional cutting method involves laying the sheet flat on a cutting table and cutting it using the rollers. However, this method can cause problems because the sheet materials are typically made of metal, which has a certain rigidity and toughness. The cutting rollers exert lateral pressure on the sheet material during cutting, which can easily cause any loose or improperly secured sheet material to shift. This not only increases the dimensional error of the cut sheet material but also leaves irregular cuts on the edges, affecting the accuracy of subsequent splicing and welding operations. Furthermore, the metal shavings generated during cutting can easily fly onto the worktable, making cleaning difficult and potentially causing cuts to operators, posing a safety hazard. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a shearing machine for the production of distribution boxes and its usage method. The technical problem to be solved by this invention is that, since the plates of distribution boxes are usually made of metal materials with a certain degree of rigidity and toughness, the cutting wheels may exert lateral extrusion force on the plates during the cutting process, which may easily cause the plates that are not pressed and fixed to shift. This not only increases the dimensional error of the cut plates, but also leaves irregular cuts on the edges of the plates, affecting the accuracy of subsequent splicing and welding operations. At the same time, the metal shavings generated during the cutting process are easy to splash onto the operating table, which is not only difficult to clean, but may also cause scratches to the operators, posing certain safety hazards.

[0015] In addition, the present invention also relates to a method of using a shearing machine for the production of distribution boxes, comprising the following steps: Step 1: After the board is aligned and fixed, turn on the external power supply of the whole device, check the running status of each moving part, and after confirming that there is no jamming fault, input the cutting parameters on the touch panel according to the preset size of the power distribution box board to be cut, and set the cutting position and cutting size information. Step 2: Start the conveying mechanism to transport the processed distribution box raw material to the feeding end of the device in sequence. The operator will then move the material to the top of the pallet one by one to complete the loading and preparation work before cutting each material. Step 3: Start the cutting drive mechanism, control the cutting wheel to feed along the preset path, and coordinate with the synchronous angle rotation of the bracket to complete the continuous cutting operation of the board and process it into a semi-finished board of the distribution box that meets the size requirements. Step 4: After a single board is cut, the cutting wheel is reset to its initial position, the bracket is controlled to rotate in the opposite direction back to its initial horizontal position, the vacuum adsorption and pressing are released, and the operator takes out the cut finished board and the remaining scraps, and sorts and stacks them in the designated area. Step 5: Repeat steps 2 to 4 to complete the batch cutting and processing of the distribution box plates. After the daily processing is completed, turn off the power of the device, open the side door of the extraction box, and thoroughly clean out the metal shavings and scraps collected inside the device to complete the daily maintenance.

[0016] The beneficial effects of this invention are as follows: This invention, by incorporating a cutting table and a positioning frame, achieves synchronized operation of sheet metal positioning, feeding, and cutting. By oriented the cutting edge of the sheet metal towards the bottom, it effectively allows scraps and debris generated during cutting to fall directly into the collection area of ​​the shearing protective shell under gravity, eliminating the need for an additional top debris guide structure. Combined with the suction collection function of the extraction box, this further improves the efficiency of debris collection and prevents long-term accumulation of debris on the processing table surface from adversely affecting the equipment's operational accuracy. Furthermore, through a multi-station coordinating fixing method, initial positioning is achieved first using negative pressure adsorption, followed by side feeding to adjust the cutting position. The material is then positioned and finally fixed by overall clamping. Layer-by-layer positioning ensures the stability of the sheet material throughout the cutting process, effectively preventing displacement caused by lateral pressure from the cutting wheels. This controls the cutting dimensional errors and ensures a smooth and even cut, preventing any adverse effects on the accuracy of subsequent splicing and welding operations. At the same time, the enclosed enclosure combined with an active exhaust debris collection system solves the problem of metal debris splashing and scattering, reducing cleaning difficulty and preventing operators from being scratched by flying debris, thus eliminating safety hazards during the operation. The overall cutting operation's accuracy, efficiency, and safety have all been significantly improved. Attached Figure Description

The bottom ends of the two vertical slide rods 2218 are fixedly connected to the tops of two sliding plates 225. A horizontal guide rail rod 227 is fixedly connected to the middle of the inner side of each of the two sliding plates 225. A second electric push rod 228 is fixedly connected to the right side of the top of each of the two sliding plates 225.

Vacuum pipes 2211 are fixedly connected to both sides of the inner sides of the two vacuum extraction plate connecting rods 2210. The top right sides of both horizontal L-shaped sliders 229 are fixedly connected to the left ends of two second electric push rods 228. Vacuum extraction plates 2212 are fixedly connected to the bottom of both vacuum extraction plate connecting rods 2210. The top sides of both vacuum extraction plates 2212 are fixedly connected to the bottom ends of two sets of vacuum pipes 2211. After the distribution box's plates are processed, the workers place them on top of the pallet 211. At this point, the two second electric push rods 228 are activated, pulling the two horizontal L-shaped sliders 229 to slide on the outer wall of the horizontal guide rail 227. The sliding of the two horizontal L-shaped sliders 229 then drives the two vacuum extraction plate connecting rods 2210 to slide, thereby moving the two vacuum extraction plates 2212 to the center of the plate. Then, the vertical electric push rod 2214 is activated, pushing the top rod 2217 downwards in the vertical direction. The top rod 2217 drives the two vertical sliding rods 2218 downwards... The guide block 222 slides down the inner wall, simultaneously driving the two sliding plates 225 to move down along the guide rail 226, so that the bottom of the two vacuum extraction plates 2212 fits against the upper surface of the material to be cut. Then, the external extraction equipment extracts air from the inside of the vacuum extraction plates 2212 through the vacuum pipe 2211. The negative pressure firmly adsorbs and fixes the material to be cut onto the two vacuum extraction plates 2212, preventing the material from shifting during the cutting process. At the same time, the two inverted L-shaped pressure rods 2219 move down synchronously with the top rod 2217 to provide auxiliary initial pressing on the area of ​​the top of the material near the cutting position, further improving the stability of the material during the cutting process. Then, the third electric push rod 2215 is activated. The two third electric push rods 2215 pull the convex side push plate 2216 to move. The movement of the convex side push plate 2216 drives the two columnar horizontal push rods 22110 to push the two rectangular side plates 221 to move. The two rectangular side plates 221 are fed to the left along the guide rail rod 2112 on the inner side of the guide side plate 217 through the concave slider 22111. This causes the board to be cut, which has been initially positioned, to move to the left as a whole until the edge of the board to be cut moves to the preset cutting position. This completes the precise adjustment of the cutting position of the board. After the cutting position is fully adjusted, the vertical electric push rod 2214 is activated to continue to lower the output end, causing the two vacuum pump plates 2212 to move down and press the board tightly against the surface of the support plate 211, completing the final fixation before cutting. After the plate positioning and adjustment are completed, the extraction box 17 and the electric push rod 19 are started. The electric push rod 19 pushes the shearing protective shell 110 to move to the right along the top of the concave side plate 11. The shearing protective shell 110 drives the cutting wheel 113 to move towards the plate to be cut, and at the same time drives the push-pull crossbars 116 at the bottom of the two side push-pull plates 114 to slide to the right along the guide groove 117. During the rightward movement of the push-pull crossbars 116, the two second rotating pull rods 2118 are pulled, which in turn drives the L-shaped support plate 2113 to move to the right along the transverse side guide plate 2114. The rightward movement of the L-shaped support plate 2113 pulls the C-shaped bottom plate 2117 through the rotating pull rods 2116, so that the entire bracket 21 is in a position where... The adapter block 219 rotates along the axis, thereby driving the bracket 21 to rotate 90 degrees. This causes the fixed plate to be cut to gradually rotate to an angle that matches the direction of travel of the cutting wheel 113, achieving synchronous linkage between plate feeding, angle adjustment and cutting action. When the bracket 21 drives the plate cutting area to the bottom, the shearing protective shell 110 moves to the outer wall of the cutting area, and the cutting wheel 113 is at the edge of the cutting area. At this time, the cutting wheel 113 can be started and controlled by the cutting wheel control component 111 to make cutting rotation, and complete continuous cutting operation along the preset cutting line of the plate to process the distribution box plate with the required size. During the cutting process, the shearing protective shell 110 always surrounds the outside of the cutting operation area to prevent metal chips generated during cutting from flying around. At the same time, the extraction box 17 continuously extracts air from the inside of the shearing protective shell 110 through the pipe 18, sucking the suspended chips and scraps into the extraction box 17 for centralized collection. This eliminates the need for workers to clean up the scattered chips after the cutting operation, reducing the workload of on-site cleaning and preventing flying chips from scratching the operators, thus improving the safety of production operations. By directing the cut edge of the sheet metal towards the bottom, the system effectively prevents scraps and debris from falling directly into the collection area of ​​the shearing protective housing 110 under gravity. This eliminates the need for an additional top debris guide structure. Combined with the suction collection system 17, the efficiency of debris collection is further improved. This also prevents debris from accumulating on the processing table surface and affecting the equipment's operational accuracy. The system employs a multi-station fixing method, first using negative pressure adsorption for initial positioning, then adjusting the cutting position through side feeding, and finally achieving final fixation through overall clamping. This layered positioning ensures the stability of the sheet metal throughout the cutting process, effectively preventing displacement caused by lateral pressure from the cutting wheels. This controls the cutting dimensional errors of the sheet metal and ensures a smooth cut, preventing any adverse impact on the accuracy of subsequent splicing and welding operations. At the same time, the enclosed enclosure combined with active suction for debris collection also solves the problem of metal debris splashing and scattering. This reduces the difficulty of post-operative cleaning and prevents operators from being scratched by flying debris, eliminating safety hazards during operation. Overall, the accuracy, efficiency, and safety of the cutting operation are significantly improved.

[0022] In addition, the present invention also relates to a method of using a shearing machine for the production of distribution boxes, comprising the following steps: Step 1: After the board is aligned and fixed, turn on the external power supply of the whole device, check the running status of each moving part, and after confirming that there is no jamming fault, input the cutting parameters on the touch panel according to the preset size of the power distribution box board to be cut, and set the cutting position and cutting size information. Step 2: Start the conveying mechanism to transport the processed distribution box raw material to the feeding end of the device in sequence. The operator will then move the material to the top of the pallet 211 one by one to complete the feeding and complete the pre-cutting work for each material. Step 3: Start the cutting drive mechanism, control the cutting wheel 113 to feed along the preset path, and cooperate with the synchronous angle rotation of the bracket 21 to complete the continuous cutting operation of the board and process the distribution box semi-finished board that meets the size requirements. Step 4: After the single board is cut, the cutting wheel 113 returns to the initial position, the control bracket 21 rotates in the opposite direction back to the initial horizontal position, the vacuum adsorption and pressing are released, and the operator takes out the cut finished board and the remaining scraps and sorts them and stacks them in the designated area. Step 5: Repeat steps 2 to 4 to complete the batch cutting and processing of the distribution box plates. After the daily processing is completed, turn off the power of the device, open the side door of the extraction box 17, and thoroughly clean out the metal scraps and offcuts collected inside the device to complete the daily maintenance.

[0023] Working principle of this invention: After the distribution box plate is processed, the worker places it on top of the pallet 211. At this time, the two second electric push rods 228 are first activated. The two second electric push rods 228 pull the two horizontal L-shaped sliders 229 to slide on the outer wall of the horizontal guide rail 227. The sliding of the two horizontal L-shaped sliders 229 drives the two vacuum extraction plate connecting rods 2210 to slide, thereby moving the two vacuum extraction plates 2212 to the center of the plate. Then, the vertical electric push rod 2214 is activated. The vertical electric push rod 2214 pushes the top rod 2217 to move downward in the vertical direction. The top rod 2217 drives the two vertical sliding rods 2218 to slide down along the inner wall of the vertical guide block 222, and at the same time drives the two sliding plates 225 to move down synchronously along the vertical guide rail 226. The bottoms of the two vacuum extraction plates 2212 are brought into contact with the upper surface of the material to be cut. Then, an external extraction device evacuates air from inside the vacuum extraction plates 2212 through vacuum pipes 2211. This negative pressure firmly adheres the material to the two vacuum extraction plates 2212, preventing displacement during cutting. Simultaneously, two inverted L-shaped pressure rods 2219 move downwards in sync with the top rod 2217, providing initial compression to the area near the cutting position on the top of the material, further enhancing stability during cutting. Then, the third electric push rod 2215 is activated. The two third electric push rods 2215 pull the convex side push plate 2216, which in turn moves the two columnar horizontal push rods 22110, pushing the two rectangular side plates 221. A rectangular side plate 221 is fed to the left along the guide rail 2112 inside the guide side plate 217 via a concave slider 22111, thereby moving the pre-positioned board material to be cut to the left until the edge of the board to be cut moves to the preset cutting position, completing the precise adjustment of the board cutting position. After the cutting position is fully adjusted, the vertical electric push rod 2214 is further activated to continue to descend the output end, driving the two vacuum extraction plates 2212 to move down and press the board tightly against the surface of the support plate 211, completing the final fixation before cutting. After the board positioning adjustment is completed, the vacuum box 17 and the electric push rod 19 are activated. The electric push rod 19 pushes the shearing protective housing 110 to move to the right along the top of the inverted concave side plate 11, and the shearing protective housing 110 drives the cutting wheel 11. 3. Move towards the board to be cut, simultaneously causing the push-pull crossbars 116 at the bottom of the two side push-pull plates 114 to slide synchronously to the right along the guide groove 117. During the rightward movement of the push-pull crossbars 116, the two second rotating pull rods 2118 are pulled, which in turn causes the L-shaped support plate 2113 to move to the right along the transverse side guide plate 2114. The rightward movement of the L-shaped support plate 2113 pulls the C-shaped base plate 2117 through the rotating pull rods 2116, causing the entire bracket 21 to rotate around the adapter block 219 as the axis of rotation, thereby causing the entire bracket 21 to rotate 90 degrees. This allows the fixed part of the board to be cut to gradually rotate to an angle that matches the direction of travel of the cutting wheel 113, realizing the synchronous linkage between the board feeding and angle adjustment and the cutting action. When the bracket 21 drives the cutting part of the board to rotate to the bottom,At this point, the shearing protective housing 110 has moved to the outer wall of the cutting area, and the cutting wheel 113 is at the edge of the cutting area. The cutting wheel 113 can then be started and controlled by the cutting wheel control unit 111 to rotate and cut along the preset cutting line of the sheet metal, completing a continuous shearing operation to obtain a distribution box sheet metal of the required dimensions. During the cutting process, the shearing protective housing 110 always surrounds the outside of the cutting area to prevent metal debris from flying in all directions. Simultaneously, the extraction box 17 continuously extracts air from the inside of the shearing protective housing 110 through the pipe 18, drawing in suspended debris and scrap for collection.
