Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a shearing machine for the production of power distribution cabinets. Background Technology

[0002] A shearing machine uses a moving upper blade and a fixed lower blade with a reasonable blade gap to apply shearing force to metal sheets of various thicknesses, causing the sheets to break and separate to the required dimensions. In the production process of electrical distribution cabinets, it is necessary to shear the required sheet metal, so a shearing machine is required.

[0003] This utility model discloses a shearing machine for power distribution cabinet production, including a chassis. A shearing mechanism is provided on the rear side of the top of the chassis for shearing sheet metal. A fixing mechanism is provided on the top of the chassis for fixing the sheet metal. The fixing mechanism includes a fixing component, comprising a sliding plate. A fixing cylinder is fixedly connected inside the sliding plate. A sliding block is fixedly connected to the top of the fixing cylinder via a piston rod. A round rod is fixedly connected inside the sliding block. A transmission component inside the sliding block causes the fixing plate to rotate. This utility model relates to the field of power distribution cabinet production technology. This shearing machine for power distribution cabinet production, driven by the fixing cylinder, causes the fixing plate to compact and fix the sheet metal for power distribution cabinet production placed on top of the placement plate, thereby maintaining the stability of the sheet metal during subsequent shearing. Simultaneously, it avoids the labor consumption caused by prolonged manual control of the sheet metal.

[0004] Existing shearing machines typically use pressure blocks to press and fix the sheet metal during the shearing process of distribution cabinets. However, since the pressing force of the pressure blocks cannot be controlled, excessive pressing force can easily damage the sheet metal, thus compromising the protective function of the device. Therefore, a shearing machine for distribution cabinet production is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a shearing machine for the production of power distribution cabinets.

[0006] The technical solution adopted by this utility model to solve its technical problem is a shearing machine for producing power distribution cabinets, including a machine body. A control panel is installed on the side wall of the machine body. A placement table is provided on the machine body, and a plate is placed on the placement table. Two sets of fixed frames are installed on the placement table. A stepper motor is mounted on one of the fixed frames via a machine base. A first lead screw is installed on the output shaft of the stepper motor. The first lead screw is rotatably mounted between the fixed frame and the placement table. A guide rod is installed between the other fixed frame and the placement table. A lifting plate is sleeved on the guide rod and the first lead screw. An indicator light is installed on the lifting plate. Multiple sets of pressure blocks are installed on the bottom side of the lifting plate. The pressure blocks have moving grooves and limiting grooves inside. Moving blocks are assembled in the moving grooves, and moving blocks are installed on the moving blocks. The device includes a limiting block with a first electrode plate installed on its inner wall and a second electrode plate installed on the inner wall of a limiting groove. A spring is installed between the limiting block and the limiting groove. The first and second electrode plates are connected to an indicator light via an internal circuit. The indicator light is also connected to a control panel via an internal circuit. By placing the plate on the placement platform, the control panel controls a stepper motor to operate, driving a lifting plate to move multiple pressure blocks vertically downwards. When the lower surface of all the pressure blocks contacts the upper surface of the plate, the indicator light sends an electrical signal to the control panel. Upon receiving the signal, the control panel stops the stepper motor. At this point, the pressure of the pressure blocks on the plate is moderate. This structure can control the pressure of the pressure blocks, preventing excessive pressure from damaging the plate and improving the device's protective properties.

[0007] Preferably, the machine body has a shearing chamber inside, and a lower blade is fixedly installed on the inner wall of the shearing chamber. A hydraulic cylinder is installed inside the machine body, and a hydraulic rod is installed on the hydraulic cylinder. An upper blade is installed on the hydraulic rod, and the inclination angle of the upper blade is 6°. A sliding groove is provided on the placement platform, and a second lead screw is rotatably installed on the inner wall of the sliding groove. The threads on the second lead screw are symmetrically opposite in direction, and a damping wheel is installed at one end of the second lead screw. Two sets of sliders are symmetrically assembled in the sliding groove, and sliding plates are installed on the sliders. Multiple sets of guide wheels are rotatably installed on the sliding plates. By placing the plate on the placement platform, the second lead screw rotates, driving the two sets of sliding plates to move synchronously relative to each other. The two sets of sliding plates drive the two rows of guide wheels to move synchronously relative to each other, so that the two rows of guide wheels are in contact with the side walls of the plate. Then, the plate is pushed, and the plate moves stably between the two rows of guide wheels, aligning the shearing line on the plate with the upper blade, thus achieving precise placement of the plate. This structure can accurately position the plate and is beneficial to improving the accuracy of plate shearing.

[0008] The advantages of this utility model are:

[0009] 1. This utility model involves placing the sheet material on a placement platform, with the control panel controlling the operation of a stepper motor to drive a lifting plate and move multiple pressure blocks vertically downwards. When the lower surface of all the pressure blocks contacts the upper surface of the sheet material, an indicator light sends an electrical signal to the control panel. Upon receiving the signal, the control panel stops the stepper motor. At this point, the pressure of the pressure blocks on the sheet material is moderate. This structure can control the pressure of the pressure blocks, preventing excessive pressure from damaging the sheet material and improving the protective properties of the device.

[0010] 2. This utility model places the sheet material on a placement platform, rotates the second lead screw, and drives two sets of sliding plates to move synchronously relative to each other. The two sets of sliding plates drive two rows of guide wheels to move synchronously relative to each other, so that the two rows of guide wheels are in contact with the side walls of the sheet material. Then, the sheet material is pushed, and the sheet material moves stably between the two rows of guide wheels, aligning the cutting line on the sheet material with the upper blade, thus achieving precise placement of the sheet material. This structure can accurately position the sheet material and is beneficial to improving the accuracy of sheet material cutting. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3 As shown, a shearing machine for producing power distribution cabinets includes a machine body 1, a control panel 2 mounted on the side wall of the machine body 1, a placement platform 3 on the machine body 1, a sheet metal 25 placed on the placement platform 3, and two sets of fixing frames mounted on the placement platform 3. A stepper motor 4 is mounted on one of the fixing frames via a machine base, and a first lead screw 5 is mounted on the output shaft of the stepper motor 4. The first lead screw 5 is rotatably mounted between the fixing frame and the placement platform 3. A guide rod 6 is mounted between the other fixing frame and the placement platform 3. A lifting plate 7 is sleeved on the guide rod 6 and the first lead screw 5. An indicator light 8 is mounted on the lifting plate 7, and an indicator light 8 is mounted on the bottom side of the lifting plate 7. There are multiple sets of pressure blocks 9. Each pressure block 9 has a moving groove 10 and a limiting groove inside. A moving block 11 is installed inside the moving groove 10, and a limiting block 12 is installed on the moving block 11. A first electrode plate 13 is installed on the inner wall of the limiting block 12, and a second electrode plate 14 is installed on the inner wall of the limiting groove. A spring 15 is installed between the limiting block 12 and the limiting groove. The first electrode plate 13 and the second electrode plate 14 are connected to an indicator light 8 via an internal circuit. The indicator light 8 is connected to a control panel 2 via an internal circuit. During operation, existing shearing machines typically use pressure blocks 9 to shear the sheet metal 25 of the distribution cabinet. 5. Pressing and fixing is performed, but since the pressing force of the pressing block 9 cannot be controlled, it is easy to cause damage to the plate 25 due to excessive pressing force, thus affecting the protective function of the device. By placing the plate 25 on the placement platform 3, the control panel 2 controls the stepper motor 4 to operate. The stepper motor 4 drives the first lead screw 5 to rotate. The first lead screw 5 drives the lifting plate 7 on it to move vertically downward. The lifting plate 7 drives multiple pressing blocks 9 to move vertically downward. The moving block 11 at the bottom of the pressing block 9 will first contact the upper surface of the plate 25 and be pushed into the moving groove 10 by the plate 25. At the same time, the moving block 11 drives the limiting block 12 to move vertically in the limiting groove. As the upper part moves, the limiting block 12 drives the first electrode plate 13 to move towards the second electrode plate 14, and the spring 15 is compressed. When the lower surface of all the pressing blocks 9 contacts the upper surface of the plate 25, the first electrode plate 13 contacts the second electrode plate 14. At this time, the internal circuit of the indicator light 8 is turned on, and the indicator light 8 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the stepper motor 4 to stop operating. At this time, the pressing force of the pressing block 9 on the plate 25 is moderate. This structure can control the pressing force of the pressing block 9, avoid excessive pressing force from damaging the plate 25, and improve the protection of the device.

[0020] Please see Figure 4-5 As shown, the machine body 1 has a shearing chamber 16 inside, and a lower blade 17 is fixedly installed on the inner wall of the shearing chamber 16. A hydraulic cylinder is installed inside the machine body 1, and a hydraulic rod is installed on the hydraulic cylinder. An upper blade 18 is installed on the hydraulic rod, and the inclination angle of the upper blade 18 is 6°. A slide groove 19 is opened on the placement table 3, and a second lead screw 20 is rotatably installed on the inner wall of the slide groove 19. The thread direction of the second lead screw 20 is symmetrical and opposite. A damping wheel 21 is installed at one end of the second lead screw 20. Two sets of sliders 22 are symmetrically assembled in the slide groove 19. A sliding plate 23 is installed on the slider 22, and multiple sets of guide wheels 24 are rotatably installed on the sliding plate 23. During operation, the existing shearing machine shears the plate 25 of the power distribution cabinet. The inability to accurately position the plate 25 resulted in poor cutting precision. By placing the plate 25 on the placement platform 3 and rotating the damping wheel 21, the second lead screw 20 was rotated. The second lead screw 20 caused the two sets of sliders 22 on it to move synchronously relative to each other. The two sets of sliders 22 caused the two sets of sliding plates 23 to move synchronously relative to each other. The two sets of sliding plates 23 caused the two rows of guide wheels 24 to move synchronously relative to each other, so that the two rows of guide wheels 24 were in contact with the two side walls of the plate 25. Then the plate 25 was pushed, and the plate 25 moved stably between the two rows of guide wheels 24, aligning the cutting line on the plate 25 with the upper blade 18, thus achieving accurate placement of the plate 25. After that, the pressure block 9 pressed and fixed the plate 25.

[0021] Then, the hydraulic cylinder operates, and the hydraulic rod drives the upper blade 18 to move vertically downward. The upper blade 18 and the lower blade 17 cut the side of the plate 25, thus achieving the cutting of the plate 25. The cut waste will fall into the shearing chamber 16. This structure can accurately position the plate 25, which is beneficial to improving the cutting accuracy of the plate 25.

[0022] Working principle: Existing shearing machines typically use pressure blocks 9 to press and fix the sheet metal 25 during the shearing process of the distribution cabinet. However, due to the inability to control the pressing force of the pressure blocks 9, excessive pressing force can easily damage the sheet metal 25, compromising the device's protective function. By placing the sheet metal 25 on the placement table 3, the control panel 2 controls the stepper motor 4 to operate. The stepper motor 4 drives the first lead screw 5 to rotate, which in turn drives the lifting plate 7 on it to move vertically downward. The lifting plate 7 then drives multiple pressure blocks 9 to move vertically downward. The moving block 11 at the bottom of the pressure block 9 will first contact the upper surface of the sheet metal 25. The plate 25 pushes the pressure block 9 into the moving groove 10. Simultaneously, the moving block 11 drives the limiting block 12 to move vertically upwards within the limiting groove. The limiting block 12 drives the first electrode plate 13 to move towards the second electrode plate 14, and the spring 15 is compressed. At the instant all the lower surfaces of the pressure blocks 9 contact the upper surface of the plate 25, the first electrode plate 13 contacts the second electrode plate 14. At this moment, the internal circuit of the indicator light 8 is activated, and the indicator light 8 sends an electrical signal to the control panel 2. After receiving the electrical signal, the control panel 2 controls the stepper motor 4 to stop operating. At this time, the pressure of the pressure block 9 on the plate 25 is moderate. This structure can control the pressure of the pressure block 9. The pressure applied should be moderate to avoid damage to the sheet metal 25 due to excessive pressure, thus improving the device's protective properties. Existing shearing machines cannot accurately position the sheet metal 25 during shearing of the distribution cabinet, resulting in poor shearing precision. By placing the sheet metal 25 on the placement table 3 and rotating the damping wheel 21, the second lead screw 20 rotates. The second lead screw 20 drives two sets of sliders 22 to move synchronously relative to each other. The two sets of sliders 22 drive two sets of sliding plates 23 to move synchronously relative to each other. The two sets of sliding plates 23 drive two rows of guide wheels 24 to move synchronously relative to each other, thus ensuring the synchronous relative movement of the two rows of guide wheels 24. The plate 25 is then pressed against the two side walls of the plate 25 and pushed. The plate 25 moves stably between the two rows of guide wheels 24, aligning the shearing line on the plate 25 with the upper blade 18, thus achieving precise placement of the plate 25. Then, the pressure block 9 presses and fixes the plate 25. After that, the hydraulic cylinder operates, and the hydraulic rod drives the upper blade 18 to move vertically downward. The upper blade 18 and the lower blade 17 shear the side of the plate 25, thus achieving shearing of the plate 25. The cut waste will fall into the shearing chamber 16. This structure can accurately position the plate 25, which is beneficial to improving the shearing accuracy of the plate 25.
