[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet, which is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits, and the motor control center is used in places where the load is concentrated and there are more circuits. The commonly used materials for distribution cabinets are wood and metal. Because the metal distribution box has a higher protection level, metal is more commonly used.

[0003] During the forming process of the distribution cabinet, the metal material needs to go through multiple processes such as shearing, stamping, and drilling.

[0004] The shearing machine in the prior art is a machine that shears plates by means of two blades that cooperate with each other, so that the plates are broken and separated into required sizes, replacing manual labor and saving manpower. However, the blades may break or curl after being used for a long time, and the sheared waste needs to be removed from the workbench manually, which poses a safety hazard for the workbench with blades. Utility Model Content

The dividing line between the waste material and the reserved material corresponds to the position of the laser cutting mechanism. During shearing, the operator can move the laser cutting mechanism and the positioning plate downward. The bottom height of the positioning plate is lower than the laser cutting mechanism, that is, the positioning plate will first contact the sheet material with the laser cutting mechanism. The elastic part arranged between the positioning plate and the laser cutting mechanism, after the positioning plate contacts the sheet material, the laser cutting mechanism can continue to move downward, and the elastic part is compressed to generate potential energy, which can be used to make the rotating shaft at the bottom of the positioning plate press the sheet material, so as to achieve the purpose of positioning the sheet material, and the laser cutting mechanism can be laser cut when it moves downward to the preset position. Compared with the cutting of the blade in the prior art, the setting of the cutting mechanism avoids the problem of safety hazards caused by the blade being exposed outside. After the laser cutting mechanism completes cutting of the sheet material, the laser cutting mechanism can be reset upward. Due to the setting of the elastic part, the laser cutting mechanism will leave the sheet material before the positioning plate and gradually release the elastic part, that is, the laser cutting mechanism will move upward relative to the positioning plate. At this time, the unloading component set can rotate the rotating shaft clockwise. The rotation of the rotating shaft can utilize the friction between the rotating shaft and the sheet material to move the cut waste. When the area of ​​the waste moving out of the shearing platform is larger than the area on the shearing platform, the waste will fall due to gravity, thereby achieving the purpose of automatic unloading, solving the problem in the prior art that the sheared waste needs to be manually removed from the workbench, and there are safety hazards for the workbench with a blade.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] refer to Figure 1-Figure 4 A sheet metal distribution cabinet shell shearing device includes a workbench 100, a shearing platform 101, a laser cutting mechanism 102, a positioning plate 103, a rotating shaft 105 and a unloading component. The shearing platform 101 is arranged in the workbench 100, the laser cutting mechanism 102 is arranged in the workbench 100, and is located on the top of the shearing platform 101. The positioning plate 103 is arranged on one side of the laser cutter 202, and its bottom is lower than the laser cutting mechanism 102. An elastic member 104 is arranged between the positioning plate 103 and the laser cutting mechanism 102, and the rotating shaft 105 is arranged at the bottom of the positioning plate 103. The unloading component is arranged between the rotating shaft 105 and the positioning plate 103, and the unloading component is used to rotate the rotating shaft 105 clockwise when the laser cutting mechanism 102 moves upward relative to the positioning plate 103.

[0032] By setting up the shearing platform 101, when in use, the operator can place the sheet metal of the power distribution cabinet that needs to be cut to shell specifications on the shearing platform 101, and the cut part is placed on the left side of the shearing platform 101. The dividing line between the waste material and the reserved material corresponds to the position of the laser cutting mechanism 102. When shearing, the operator can move the laser cutting mechanism 102 and the positioning plate 103 downward. The bottom of the positioning plate 103 is lower than the laser cutting mechanism 102, that is, the positioning plate 103 will contact the sheet material before the laser cutting mechanism 102. An elastic member 104 is set between the positioning plate 103 and the laser cutting mechanism 102. After the positioning plate 103 contacts the sheet material, the laser cutting mechanism 102 can continue to move downward. The elastic member 104 is compressed to generate potential energy. The potential energy can be used to make the rotating shaft 105 at the bottom of the positioning plate 103 press the sheet material, so as to achieve the purpose of positioning the sheet material. When the laser cutting mechanism 102 moves downward to the preset position, the sheet material can be laser cut. Compared with the cutting of the blade in the prior art, the setting of the laser cutting mechanism 102 avoids the problem of safety hazards caused by the blade being exposed outside. After the laser cutting mechanism 102 completes cutting of the sheet material, the laser cutting mechanism 102 can be reset upward. Due to the setting of the elastic member 104, the laser cutting mechanism 102 will leave the sheet material before the positioning plate 103 and gradually release the elastic member 104, that is, the laser cutting mechanism 102 will move upward relative to the positioning plate 103. At this time, the unloading component set can rotate the rotating shaft 105 clockwise. The rotation of the rotating shaft 105 can utilize the friction between the rotating shaft 105 and the sheet material to move the cut waste. When the area of ​​the waste moving out of the shearing platform 101 is larger than the area on the shearing platform 101, the waste will fall due to the influence of gravity, thereby achieving the purpose of automatic unloading, solving the problem that the sheared waste needs to be manually removed from the workbench 100 in the prior art, and there is a safety hazard for the workbench 100 with a blade.

[0033] As a further feature of the present invention, the laser cutting mechanism 102 includes a bracket 200 disposed in the workbench 100 , a screw rod 201 is disposed in the bracket 200 , a laser cutter 202 is threadedly connected to the screw rod 201 , and a motor 203 connected to the screw rod 201 is disposed on the bracket 200 .

[0034] By setting up the laser cutter 202, when in use, the position of the bracket 200 can be moved downward, and the downward movement of the bracket 200 can drive the laser cutter 202 to move. When the bracket 200 and the laser cutter 202 move downward to a preset position, the laser cutter 202 can be turned on and the motor 203 can be started. The motor 203 drives the laser cutter 202 to move through the screw rod 201 to achieve the purpose of cutting the sheet material.

[0035] As a further feature of the present invention, a side opening 300 is provided on one side of the positioning plate 103, a limiting rod 301 is connected inside the side opening 300, a support rod 302 connected to the bracket 200 is slidably connected to the limiting rod 301, and the elastic member 104 is connected between the support rod 302 and the side opening 300.

[0036] By setting a limit rod 301, the cooperation between the limit rod 301 and the support rod 302 can realize the setting of the positioning plate 103 on one side of the bracket 200. When the bracket 200 moves downward, the positioning plate 103 can be driven to move downward under the action of the support rod 302 and the elastic member 104. After the positioning plate 103 contacts the sheet material, the bracket 200 can continue to move downward to compress the elastic member 104 and use the force of the elastic member 104 to position the sheet material.

[0037] As a further feature of the present invention, the unloading component includes a connecting shaft 303 connected to the bottom of the positioning plate 103, a rotating shaft 105 is arranged outside the connecting shaft 303, the rotating shaft 105 is cylindrical, a spring 304 is connected between the connecting shaft 303 and the positioning plate 103, a traction rope 305 is connected to the top of the support rod 302, one end of the traction rope 305 passes through the side opening 300 and is wound around the connecting shaft 303, and a ratchet mechanism 306 is arranged between the rotating shaft 105 and the connecting shaft 303. The spring 304 is a torsion spring.

[0038] By setting the traction rope 305, after the positioning plate 103 contacts the sheet material, the bracket 200 and the support rod 302 will move downward, and the traction rope 305 can be pulled, and the traction rope 305 drives the connecting shaft 303 to rotate. The rotation of the connecting shaft 303 generates potential energy for the spring 304. Since the ratchet mechanism 306 is set between the connecting shaft 303 and the rotating shaft 105, the rotating shaft 105 presses the sheet material to generate friction, that is, the connecting shaft 303 will idle in the rotating shaft 105. When the bracket 200 is reset, the support rod 302 will move upward relative to the position of the positioning plate 103. The connecting shaft 303 rotates in the opposite direction under the force of the spring 304 and reels the traction rope 305. The reverse rotation of the connecting shaft 303 can drive the rotating shaft 105 to rotate clockwise through the ratchet mechanism 306, thereby achieving the purpose of rotating the rotating shaft 105 to unload the waste material. The direction of the traction rope 305 can be changed by a fixed pulley installed on the top plate 103.

[0039] As a further feature of the present invention, a plurality of positioning cones 400 are connected to the top of the shearing platform 101 , and a plurality of transmission shafts 401 are also rotatably connected to the top of the shearing platform 101 .

[0040] By setting the positioning cone 400, when the plate is placed on the positioning cone 400, the positioning cone 400 can increase the friction of the plate when it moves, and can improve the stability of the plate after it is placed on the shearing platform 101. A transmission shaft 401 is set, and a dividing line is formed between the transmission shaft 401 and the positioning cone 400. When used, the dividing line can be the dividing line for cutting the plate. When the rotating shaft 105 rotates to unload waste, the friction between the waste and the shearing platform 101 can be reduced, and the waste can be unloaded more smoothly.

[0041] As a further feature of the present invention, an electric push rod 402 is connected to the top of the workbench 100 , and a telescopic shaft of the electric push rod 402 is connected to the bracket 200 .

[0042] By providing the electric push rod 402 , the electric push rod 402 can provide driving force for the up and down movement of the bracket 200 .

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
