[0001] The invention relates to the field of high-voltage distribution cabinet production, and in particular to a high-voltage distribution cabinet production molding device and a working method thereof. Background Art

[0002] A high-voltage distribution cabinet refers to a switch, control or protection device used in power generation, transmission, distribution, power conversion and consumption of a power system. In the production of high-voltage distribution cabinets, after the plate is placed under the pressing plate by manual or general feeding structure, its position is prone to certain deviations.

When the induction control system detects that the metal sheet moves to the position of the punching device and the forming device, the upper conveyor chain stops moving, so that the punching device and the forming device respectively perform punching and stamping operations on the metal sheet. The punching device includes an upper die and a die. The die is arranged on a fixed bracket and is located between the two upper conveyor chains. A lifting platform is also arranged below the die. The lifting platform can drive the die to move up and down, and a through sleeve is arranged on the die. The through sleeve penetrates the die and extends downward.

[0008] More preferably, the forming device includes a forming punch and a forming mold. The forming punch has a rectangular cross-section and is located above a fixed bracket. The upper and lower ends of the forming mold are both rectangular cylinders with open ends. The forming mold is located between two upper conveying chains, and a support platform is provided at the lower end of the forming mold.

[0009] More preferably, a demoulding rod is provided on the bottom surface of the forming punch, and the demoulding rod is retractable and can apply thrust downward.

[0010] More preferably, a limited slide is provided in the fixed bracket, both ends of the support platform are arranged in the limited slide, and rollers are provided in the limited slide, the support platform can move in the limited slide through the rollers, and an electric telescopic cylinder is also connected to the support platform, and the support platform can be controlled to move in the limited slide through the electric telescopic cylinder.

[0012] A working method of a high-voltage distribution cabinet production molding device comprises the following steps:

[0013] S1. First, place the metal sheet on the cutting table. Then, the staff draws the outline and specific size of the metal sheet to be cut in the CAD software according to the specifications of the cabinet. Then, the CAM software converts the figure into a code that can be recognized by the CNC system. Then, the code is input into the CNC plasma cutting machine. The CNC plasma cutting machine can accurately cut the metal sheet along the CAD outline drawn by the staff.

[0014] S2. After the metal sheet is cut into a "cross" shape by a CNC plasma cutting machine, the staff collects the remaining waste after cutting for recycling, and then places the cut "cross" shaped metal sheet on the upper conveyor chain, and places the new metal sheet on the cutting table;

[0015] S3. The cabinet waiting to be formed falls from the forming mold to the lower conveyor belt, and then the lower conveyor belt drives the cabinet to slide down the unloading slope. The staff needs to receive and inspect the cabinet on the unloading slope, check the heat dissipation holes on the left and right side walls of the cabinet, as well as the power hole, cable inlet and outlet hole, and ground wire hole on the back of the cabinet, and check whether all holes are opened;

[0016] S4. After the staff checks that all holes have been drilled, the cabinet is moved to the welding table, the joints between the side walls of the cabinet are welded by welding equipment, and the welded cabinet is polished. After polishing, the cabinet door only needs to be installed on the cabinet through the connector.

[0017] Compared with the prior art, the beneficial effect of the present invention is as follows: a metal sheet cut into a "cross" shape is placed on the upper conveyor chain, so that it drives the metal sheet to move; when the induction control system detects through the infrared sensor and the positioning camera that the metal sheet moves to the position of the punching device, the induction control system controls the upper conveyor chain to stop moving, and when the induction control system controls the lifting platform to rise, the penetration sleeve will be separated from the trigger switch, so that the trigger switch is in a disconnected state, thereby making the upper conveyor chain unable to operate, and at the same time controlling the punching device to punch the metal sheet; after the punching is completed, the induction control system controls the lifting platform to descend, and at the same time drives the penetration sleeve to descend, so that the auxiliary push column protrudes from the penetration sleeve, so that the metal sheet is demolded by the auxiliary push column to prevent adhesion, so that the metal sheet falls back on the upper conveyor chain, and when the lifting platform is completely descended, the penetration sleeve contacts the trigger switch, so that the trigger switch is in a closed state. The upper conveyor chain can be started at this time to avoid incomplete descent caused by a malfunction of the lifting platform, or the upper conveyor chain being started prematurely during descent. After the upper conveyor chain is started, it continues to drive the metal sheet to move. When the induction control system senses through the pressure sensor that the metal sheet has moved to the position of the forming device, the induction control system controls the upper conveyor chain to stop moving, and the forming device stamps and forms the metal sheet to form an integrally formed cabinet. The induction control system controls the movement of the support table to make the formed cabinet fall onto the lower conveyor belt, and then the four sides of the cabinet are manually welded, and the cabinet door can be installed. The workload of the staff in the entire production process is very small, which can greatly reduce the labor cost, and can realize large-scale production and manufacturing more accurately and quickly. It is suitable for use in mountainous construction or overseas construction, and the one-piece cabinet is much stronger and more durable than the spliced ​​cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] See also Figures 1 to 10 As shown, a high-voltage distribution cabinet production and forming device and a working method thereof include a conveying structure, an induction control system, a punching device and a forming device. The conveying structure can drive the metal sheet to move to the position where the punching device is located, and then the position of the metal sheet is sensed by the induction control system and the metal sheet is processed by the punching device and the forming device, wherein the conveying structure includes a supporting base, an upper conveying chain 1 and a lower conveying belt 2, the supporting base is also connected to a fixed bracket 3, an annular slide 4 is arranged in the fixed bracket 3, the upper conveying chain 1 is arranged in the annular slide 4, the upper conveying chain 1 can move in the annular slide 4, and the lower conveying The belt 2 is arranged on the supporting base, and there is a gap between the two upper conveying chains 1. The two ends of the metal sheet are placed on the upper conveying chains 1, and the middle end of the metal sheet is located in the gap between the two upper conveying chains 1. The metal sheet can be driven to move by the upper conveying chains 1, and anti-dropping limit plates 5 are also arranged on both sides of the fixed bracket 3. The anti-dropping limit plates 5 can limit the metal sheet to prevent it from falling off or shifting. When the induction control system detects that the metal sheet moves to the position of the punching device, the upper conveying chain 1 stops moving, so that the metal sheet stays under the punching device, and then the punching device performs a punching operation on it.

[0033] Wherein, the punching device includes an upper die 6 and a die 7. The die 7 is arranged in the gap between the two upper conveying chains 1 in the fixed bracket 3, and a lifting platform 8 is arranged below the die 7. The lifting platform 8 is fixedly arranged on the fixed bracket 3. Under normal conditions, the horizontal plane where the top of the die 7 above the lifting platform 8 is located is lower than the upper surface of the upper conveying chain 1. When the lifting platform 8 rises, the plane where the top of the die 7 on the lifting platform 8 is located will be higher than the plane where the upper conveying chain 1 is located. A through sleeve 801 is also arranged on the die 7. The interior of the through sleeve 801 is a hollow cylindrical structure. The upper end of the through sleeve 801 is flush with the upper surface of the die 7, and the lower end of the through sleeve 801 penetrates the die 7 and extends downward. An auxiliary ejector column 802 is inserted into the through sleeve 801. The auxiliary ejector column 80 The lower end of 2 is connected to the chassis part of the lifting platform 8, and the top of the auxiliary top column 802 can fit with the bottom surface of the metal sheet on the upper conveying chain 1. Therefore, under normal conditions, the upper surface of the auxiliary top column 802 is higher than the height of the upper surface of the die 7. When the lifting platform 8 controls the die 7 to drive the through sleeve 801 to rise, the position of the auxiliary top column 802 remains unchanged. Therefore, the height of the upper surface of the die 7 will gradually exceed the height of the upper surface of the auxiliary top column 802, so that the die 7 supports the metal sheet, thereby performing a stamping operation on the metal sheet, and a plurality of different punches are provided in the upper die 6, and corresponding grooves are also provided in the die 7, so that all the required holes of the back plate and the side plate of the high-voltage distribution cabinet can be punched through by one punching, including the control power hole, the cable inlet and outlet hole, the ground wire hole and the heat dissipation hole, etc.;When the upper conveyor chain 1 stops moving, the metal sheet is located above the die 7, and the upper die 6 is located above the metal sheet, the die 7 moves upward to support the metal sheet, and at the same time the upper die 6 descends to punch the metal sheet to form corresponding holes on the metal sheet, and after the punching is completed, the lifting platform 8 drives the die 7 to descend, so that the through sleeve 801 follows and descends, and at this time the position of the auxiliary ejector 802 remains unchanged, so the auxiliary ejector 802 will gradually eject the metal sheet attached to the die 7 from the through sleeve 801, so that the metal sheet and the die are in contact with each other. The mold 7 is detached and re-positioned on the upper conveying chain 1, and a trigger switch 803 is also provided at the lower end of the auxiliary top column 802. The trigger switch 803 is a normally closed switch. The trigger switch 803 is connected to the induction control system. When the lifting platform 8 is in a normal state, the lower end of the through-sleeve 801 fits with the trigger switch 803 of the auxiliary top column 802 to make the trigger switch 803 in a closed state. When the lifting platform 8 rises, the lifting platform 8 drives the through-sleeve 801 to move upward at the same time, so that the through-sleeve 801 is detached from the trigger switch 803, so that the trigger switch 803 is in an open state. When the trigger switch 803 is in the disconnected state, the upper conveying chain 1 cannot be started. Only when the lifting platform 8 is completely lowered and the lifting platform 8 drives the through-tube 801 to be in the normal state, the trigger switch 803 senses the through-tube 801 and switches to the closed state. Only when the trigger switch 803 is closed, the upper conveying chain 1 can continue to operate, so that the upper conveying chain 1 drives the metal sheet to the position of the forming device, and a positioning camera 804 is also arranged at the top of the auxiliary top column 802, and a groove is arranged at the top of the auxiliary top column 802. The machine 804 is set in the groove. When the auxiliary ejector column 802 ejects the metal sheet, it avoids affecting the positioning camera 804. The positioning camera 804 is connected to the induction control system. The positioning camera 804 can choose a smart industrial camera of Keyence or Cognex brand. The smart industrial camera is equipped with a built-in image analysis and processing function. The recognition area of ​​the positioning camera 804 can be set through simple operation. When the metal sheet on the upper conveyor chain 1 enters the recognition area set by the positioning camera 804, the positioning camera 804 will send a signal to the induction control system. ;

[0034] The above-mentioned forming device includes a forming punch 9 and a forming die 10. The forming punch 9 is a rectangular block structure, and a demolding rod 16 is also arranged on the bottom surface of the forming punch 9. The demolding rod 16 can be extended and retracted downward at the bottom of the forming punch 9. Under normal conditions, the bottom of the demolding rod 16 and the bottom of the forming punch 9 are located on the same horizontal plane. When demolding is required, the demolding rod 16 extends downward and retracts into the forming punch 9 after demolding is completed. The forming punch 9 is located above the fixed bracket 3. The upper and lower ends of the forming die 10 are both rectangular cylinders with open ends. The forming die 10 is located between the two upper conveying chains 1. A support table 11 is arranged at the lower end of the forming die 10, and a limiting slide 12 is arranged in the fixed bracket 3. Both ends of the support table 11 are arranged in the limiting slide 12, and rollers are arranged in the limiting slide 12, so that the support table 11 can be moved in the limiting position through the rollers. The support platform 11 moves in the slide 12, and an electric telescopic cylinder 13 is also connected to the support platform 11, which can control the support platform 11 to move in the limit slide 12 through the electric telescopic cylinder 13, so that the support platform 11 can be translated laterally. When the electric telescopic cylinder 13 drives the support platform 11 to translate to the left, the support platform 11 is located at the bottom of the forming mold 10, and fits with the forming mold 10 to form a complete lower mold, and cooperates with the forming punch 9 to perform stamping and forming operations on the metal sheet. When the electric telescopic cylinder 13 drives the support platform 11 to translate to the right, the support platform 11 is separated from the forming mold 10, so that the bottom of the forming mold 10 is open, and then the demolding rod 16 at the bottom of the forming punch 9 is controlled to extend, so that the demolding rod 16 applies a downward thrust to the cabinet, so that the cabinet falls from the forming mold 10 to the lower conveyor belt 2, and then moves to the unloading slope with the lower conveyor belt 2.

[0035] The start and stop time of the operation between the above-mentioned equipment needs to be controlled by an induction control system. The induction control system includes an infrared sensor 14, a pressure sensor 15, a PLC control module and an electric control switch. The infrared sensor 14 is composed of a transmitter and a receiver. The transmitter and the receiver are respectively arranged on the outside of the upper mold 6 and the concave mold 7. When the metal sheet moves on the upper conveyor chain 1, the front end of the metal sheet will block the infrared sensor 14, so that the infrared signal between the infrared sensor 14 is interrupted. At this time, the infrared sensor 14 will transmit the information to the PLC control module, and the recognition signal of the positioning camera 804 will also be sent to the PLC control module. After receiving any signal from the infrared sensor 14 and the positioning camera 804, the PLC control module will not issue a stop command to the electric control switch. Only when the PLC control module receives the infrared sensor 1 4 and the dual signals of the positioning camera 804, the PLC control module will control the upper conveyor chain 1 to stop running through the electric control switch. However, when the PLC control module wants to control the upper conveyor chain 1 to run through the electric control switch, it must be in the closed state of the trigger switch 803. The upper conveyor chain 1 can only be operated when the electric control switch and the trigger switch 803 are both closed. When either of them is in the disconnected state, the upper conveyor chain 1 cannot be operated, so as to avoid the situation that the upper conveyor chain 1 runs when the lifting platform 8 has not completely descended. At the same time, the PLC control module will control the lifting platform 8 to rise, and the punching device will run to perform punching operations on the metal sheet. When the punching operation is completed, the PLC control module controls the lifting platform 8 to descend, and then controls the upper conveyor chain 1 to run through the electric control switch to make the metal sheet continue to move.

[0036] Among them, the pressure sensor 15 is located at the end of the upper conveying chain 1, and an adjustable limit mechanism is also provided at the end of the upper conveying chain 1. The adjustable limit mechanism is connected to the anti-slip limit plate 5. The adjustable limit mechanism includes a positioning strip plate 18 and a screw motor 20. An adjustment groove 19 is provided on the anti-slip limit plate 5. The positioning strip plate 18 is arranged in the adjustment groove 19, and the positioning strip plate 18 can move in the adjustment groove 19. The screw motor 20 is connected to the anti-slip limit plate 5, and the moving slider of the screw motor 20 is connected to the positioning strip plate 18, so that the moving slider of the screw motor 20 can drive the positioning strip plate 18 to move in the adjustment groove 19, thereby changing the positioning according to different needs. The distance between the strip 18 and the forming device, the pressure sensor 15 is set on the positioning strip 18, and the pressure sensor 15 can transmit the signal to the PLC control module. When the metal sheet moves to the positioning strip 18 through the upper conveying chain 1, the pressure sensor 15 senses the pressure and sends a signal to the PLC control module. The PLC control module controls the upper conveying chain 1 to stop running through the electric control switch. At the same time, the PLC control module will control the operation of the forming device to stamp the metal sheet. After stamping and forming, the PLC control module will control the electric telescopic cylinder 13 to drive the support platform 11 to move, so that the formed cabinet falls from the forming mold 10 into the lower conveying belt 2.

[0037] When in use, first place the metal sheet on the cutting table, and then the staff will draw the outline graphics and specific dimensions of the metal sheet to be cut in the CAD software according to the specifications of the cabinet, and then use the CAM software to convert the graphics into a code that can be recognized by the CNC system, and then input the code into the CNC plasma cutting machine. The CNC plasma cutting machine can accurately cut the metal sheet along the CAD outline graphics drawn by the staff, so that the cut metal sheet forms a "cross" shape, and at the same time collect the remaining waste after cutting for recycling such as regeneration or smelting, and then place the cut "cross" shaped metal sheet on the upper conveyor chain 1, and while the metal sheet is limited by the anti-slip limit plate 5, the upper The conveyor chain 1 will drive the metal sheet to move. When the metal sheet moves to the position of the upper die 6 and the die 7, the metal sheet will block the infrared sensor 14, and the positioning camera 804 will detect that the metal sheet has entered the identification area. After double positioning and identification, the PLC control module will control the upper conveyor chain 1 to stop running through the electric control switch, and control the lifting platform 8 to rise. While the lifting platform 8 rises, the die 7 drives the through sleeve 801 to move upward with the lifting platform 8, so that the through sleeve 801 is separated from the trigger switch 803, and the trigger switch 803 is in the disconnected state, ensuring that the upper conveyor chain 1 cannot move. At this time, the metal sheet is located between the upper die 6 and the die 7. After the die 7 moves upward, it contacts the metal sheet. At the same time, the upper die 6 operates to press down , the metal sheet is punched through the upper die 6 and the concave die 7 to form different hole positions such as control power supply holes, cable inlet and outlet holes, ground wire holes and heat dissipation holes on the metal sheet. After the punching is completed, the upper die 6 moves upward to reset, and the PLC control module controls the lifting platform 8 to move downward to reset. When the lifting platform 8 drives the concave die 7 to descend, the auxiliary ejector column 802 will gradually protrude from the through sleeve 801, and the metal sheet will be pushed down from the concave die 7 to realize the demoulding operation, so that the metal sheet falls completely on the upper conveying chain 1, and through the complete fall of the lifting platform 8, the through sleeve 801 contacts the trigger switch 803 on the auxiliary ejector column 802 again, so that the trigger switch 803 is in a closed state again, and then the PLC control module controls the electric control switch The upper conveyor chain 1 starts, driving the metal sheet to move, so that the metal sheet moves to the position of the positioning strip 18 and contacts the positioning strip 18. At this time, when the pressure sensor 15 on the positioning strip 18 detects that the metal sheet arrives at the positioning strip 18, the PLC control module controls the upper conveyor chain 1 to stop running through the electric control switch, and controls the forming punch 9 to move downward, so that the forming punch 9 combines with the forming mold 10 and the support platform 11 to punch the metal sheet into the shape of the cabinet, and then the forming punch 9 moves upward to reset. At the same time, the PLC control module controls the electric telescopic cylinder 13 to contract, so that the electric telescopic cylinder 13 drives the support platform 11 to move in the limit slide 12, so that the cabinet falls from the forming mold 10 to the lower conveyor belt 2.Then the PLC control module controls the start of the upper conveyor chain 1 through the electric control switch, and controls the electric telescopic cylinder 13 to push the support platform 11 to reset, so that the support platform 11 is re-positioned under the forming mold 10, and the cabinet that falls on the lower conveyor belt 2 is driven by the lower conveyor belt 2 to slide down the unloading slope. The staff needs to receive and inspect the cabinet at the unloading slope, check the heat dissipation holes on the left and right side walls, and the power holes, cable inlet and outlet holes, ground wire holes, etc. on the back. When checking, the staff can use a hole position inspection ruler. Both sides of the hole position inspection ruler are provided with hole position protrusions, which correspond to the hole positions on the back of the cabinet and the hole positions on the side walls of the cabinet respectively. When checking, you only need to insert the protrusions of the hole position inspection ruler into the holes of the cabinet to make the hole position inspection ruler fit with the cabinet. When the hole position inspection ruler can fit with the cabinet When the hole is not drilled, it means that the hole has been drilled. When a hole is not drilled, the hole inspection ruler and the cabinet body cannot be completely fitted. At this time, the staff only needs to check the holes on the side wall, and then find the holes that have not been drilled, and perform manual punching operations to drill the holes that have not been drilled. After the staff checks that all holes have been drilled, the cabinet body is moved to the welding table, and the joints between the side walls of the cabinet body are welded by welding equipment, and the welded cabinet body is polished. After the polishing is completed, only the cabinet door needs to be installed on the cabinet body through hinges or hinges, which greatly reduces the amount of manual operation and can be quickly mass-produced, which can quickly and effectively support mountain construction or overseas construction development.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

A trigger switch is also provided at the lower end of the auxiliary top column. The trigger switch is a normally closed switch. When the lifting platform rises, the lifting platform drives the through-sleeve to move upward at the same time, so that the through-sleeve is separated from the trigger switch, thereby making the trigger switch in the disconnected state. A positioning camera is provided at the upper end of the auxiliary top column, and the trigger switch and the positioning camera are both connected to the induction control system. When the metal sheet moves to the position of the upper die and the die, the metal sheet blocks the infrared sensor, and the positioning camera detects that the metal sheet enters the identification area. After double positioning and identification, the PLC control module will control the upper conveying chain to stop running through the electric control switch.
