Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal forming, and more specifically, to an intelligent continuous ring main unit sheet metal forming device. Background Art

[0002] A ring main unit is a set of high-voltage switchgear installed in a metal sheet cabinet or made into a assembled sectionalized ring main unit power supply unit. The processing of metal sheets is called sheet metal processing. Sheet metal parts are thin sheet metal parts, that is, parts that can be processed by means such as stamping, bending, and stretching. During the manufacturing process of the ring main unit, it is necessary to bend the metal sheets of the ring main unit shell to strengthen the structure, avoid scratching the user with sharp corners of the sheet metal, and facilitate the assembly between the sheets.

[0003] During the bending and forming process of the existing ring main unit sheet metal parts, the sheet needs to be bent multiple times. During the multiple bending processes, it is often necessary to manually adjust and correct the position to prevent the sheet from being bent at an incorrect position during the bending process. However, the method of manually adjusting and correcting the position greatly reduces the forming efficiency of the sheet. At the same time, when manually adjusting the position of the incompletely processed sheet, there may also be safety problems, such as scratching the hand by the unprocessed edge of the sheet. Therefore, in the prior art, when processing and bending sheet metal parts, firstly, the working efficiency is low and continuous operation cannot be completed; secondly, during the process of processing the sheet, rapid positioning cannot be achieved, and it is easy to cause safety problems for workers during the positioning process.

[0021] Specifically, an X-axis slide rail 11 and a Y-axis slide rail 12 are provided on the operating rack 1, and the Y-axis slide rail 12 is arranged on the end side of the X-axis slide rail 11. Among them, the moving pressing component 2 is sleeved on the X-axis slide rail 11, and the moving pressing component 2 is slidably connected to the X-axis slide rail 11; the plate hole pressing component 6 is sleeved on the Y-axis slide rail 12, and the plate hole pressing component 6 is slidably connected to the Y-axis slide rail 12, so that after the plate is moved from the head end in the X-axis direction to the end, the plate hole pressing component 6 drives the plate to move and process in the Y-axis direction. In this embodiment, a clamping power-on trigger 111 is provided on the X-axis slide rail 11, and the clamping power-off trigger 111 is a signal-triggered power supply component. When the moving pressing component 2 disconnects the power supply of the clamping part through the clamping power-off trigger 111, the clamping state is powered off and changed to the released state.

It should be noted here that the clamping power-off trigger 111, the punching trigger 121 and the contact trigger 122 are all piezoelectric trigger elements. Utilizing the characteristics of piezoelectric materials, a voltage signal is generated when pressed to control the start and stop of the corresponding components. The piezoelectric trigger element is a prior art and will not be elaborated here.

[0022] Specifically, the moving pressing component 2 includes a moving telescopic component 21, a first pressing plate 22, a positioning plate 23, an upper clamping mechanism 24, and a lower clamping mechanism 25. The moving telescopic component 21 is sleeved on the X-axis slide rail 11, and the moving telescopic component 21 is slidably connected to the X-axis slide rail 11. The moving telescopic component 21 further includes a telescopic rod and a driving motor, and the output end of the driving motor is connected to the telescopic rod to enable the driving motor to control the telescopic rod to move in the height direction. The first pressing plate 22 is installed at the upper end of the moving telescopic component 21, and the first pressing plate 22 is fixedly connected to the moving telescopic component 21, so that when the moving telescopic component 21 moves, it drives the first pressing plate 22 to move, and the first pressing plate 22 is used to place the fixed plate. The positioning plates 23 are arranged on both sides of the starting end of the first pressing plate 22, and the positioning plates 23 enclose a limiting cavity at the two included angles of the first pressing plate 22, so that the plate is placed in the limiting cavity at the two included angles on both sides for limiting the plate.

The lower clamping mechanism 25 is arranged at the lower end of the first pressing plate 22. Among them, the lower clamping mechanism 25 includes a lower clamping part and a lower driving part, and the lower driving part is used to control the lower clamping part to move towards the upper end direction of the first pressing plate 22 to press the plate on the first pressing plate 22 from the lower end to the upper end.

[0023] Specifically, the bending assembly 3 is installed on both sides of the rear end of the moving pressing assembly 2, and the bending assembly 3 is used to punch the parts of the plate to be bent placed on the first pressing plate 22, so as to form a bent part on the plate. The bending assembly 3 includes a first telescopic assembly 31, a bending module 32 and a first driving member 33. The first telescopic assembly 31 is installed on both sides of the moving track of the moving pressing assembly 2, and is installed between the moving pressing assembly 2 and the fixed pressing assembly 4 in the initial state. The first telescopic assembly 31 includes a support base and a first telescopic rod. The support base is fixedly installed on the upper end surface of the operation frame 1. A contraction cavity is formed in the middle of the support base. The first telescopic rod is placed in the contraction cavity, and the first telescopic rod is connected to the output end of the first driving member 33 to control the telescopic movement of the first telescopic rod through the first driving member 33; wherein, the first telescopic rod has the ability to move in the height direction to realize the downward bending of the plate. The bending template 32 is arranged at the upper end of the first telescopic assembly 31, and a first bending part 321 and a second bending part 322 are respectively arranged on both sides of the bending template 32. The first bending part 321 is installed at one end close to the first pressing plate 22, and when in the initial position, it is used to bend the plate placed on the first pressing plate 22 in the initial position. The second bending part 322 is installed at one end close to the fixed pressing assembly 4. After the bending of the plate in the initial position is completed, the moving pressing assembly 2 moves to the upper end of the fixed pressing assembly 4 through the X-axis slide rail 11, and at the same time triggers the clamping power-off trigger 111, so that the upper clamping mechanism 24 and the lower clamping mechanism 25 are disconnected from the clamping state, so as to transfer the plate on the upper end of the moving pressing assembly 2 to the fixed pressing assembly 4. The second bending part 322 is used to bend the plate placed on the fixed pressing assembly 4 to bend both sides of the plate that need to be bent. The first driving member 33 is installed at the upper end of the bending template 32, and the first driving member 33 is fixedly connected to the upper end of the bending template 32.

[0024] Specifically, the fixed pressing assembly 4 is installed at the end of the X-axis slide rail 11, and the fixed pressing assembly 4 includes a second pressing plate 41, a baffle 42, a pressing plate 43 and a pressing trigger 44. The lower end of the second pressing plate 41 extends and is fixedly connected to the end face of the operating frame 1. A bent limiting plate 411 is provided at one end of the second pressing plate 41 away from the movable pressing assembly 2. The bent limiting plate 411 is matched with the bent part of the plate after being bent at the front end, and a bent edge 412 is provided at the connection between the bent limiting plate 411 and the second pressing plate 411. The radian of the bent edge 412 is matched with the bending radian of the bent plate, so that the initially bent plate is placed in a fitting manner on the second pressing plate 41. Wherein, a plate limiting cavity is formed between the bent limiting plate 411 and the baffle 42, so that when the movable pressing assembly 2 is transferred to the fixed pressing assembly 4, the movable pressing assembly 2 clamps the plate bent on one side in the plate limiting cavity to realize the transfer of the plate. The pressing plate 43 is installed between the bent limiting plate 411 and the baffle 42, and the pressing plate 43 and the baffle 42 are connected by a telescopic member. When the pressing trigger 44 is triggered, the telescopic member controls the pressing plate 43 to move towards the bent limiting plate 411, so as to squeeze the distance between the bent limiting plate 411 and the pressing plate 43 to squeeze and fix the bent part of the plate. Wherein, the pressing trigger 44 is installed on one side of the bent limiting plate 411, close to the bent limiting plate 411, to ensure that the bent plate presses the pressing trigger 44 after entering, and the contact trigger 44 is arranged at the opening of the plate limiting cavity close to the boosting assembly 5. It should be noted here that the contact trigger 44, the clamping power-off trigger 111, the punching trigger 121 and the contact trigger 122 mentioned above are all piezoelectric trigger elements, which will not be elaborated here.

[0025] Specifically, the boosting assembly 5 is installed on one side of the fixed pressing assembly 4, and the plate hole pressing assembly 6 is installed on the other side of the fixed pressing assembly 4. The boosting assembly 5 includes a boosting fixing plate 51, a boosting plate 52, and a boosting driving member 53. The installation height of the boosting fixing plate 51 is higher than that of the second pressing plate 41. Among them, the boosting plate 52 is installed on the side of the boosting fixing plate 51 close to the fixed pressing assembly 4, and the installation height of the boosting plate 52 is located at the upper end surface of the second pressing plate 41. When the boosting plate 52 is pushed out, the boosting plate 52 abuts against the upper end surface of the second pressing plate 41, and the boosting plate 52 is slidably connected to the upper end surface of the second pressing plate 41. A boosting rod 521 is arranged inside the boosting plate 52. The boosting rod 521 has the ability to expand and contract, and the boosting rod 521 is connected to the output end of the boosting driving member 53 to control the movement of the boosting rod 521 through the boosting driving member 53. The boosting driving member 53 is installed on the upper end of the boosting fixing plate 51, and the boosting driving member 53 is fixedly connected to the boosting fixing plate 51. It should be noted here that the boosting driving member 53 is electrically connected to the contact triggering member 122. When the contact triggering member 122 sends a signal, the boosting driving member 53 drives the boosting plate 51 to push the processed sheet on the fixed pressing assembly 4. It should be noted here that the aforementioned pressing triggering member 44 is installed near the open end of the boosting assembly 5 because when the boosting assembly 5 pushes the processed sheet, the processed sheet will move away from the pressing triggering member 44, releasing the pressing force of this part on the processed sheet to realize the subsequent transfer of the sheet on the fixed pressing assembly 4 to the plate hole pressing assembly 6.

[0026] Specifically, the plate hole pressing assembly 6 includes a movable sleeve 61, a third pressing plate 62, a positioning groove 63, a positioning assembly 64 and a pressing trigger assembly 65. The movable sleeve 61 is sleeved on the Y-axis slide rail 12, and in the initial state, the movable sleeve 61 is installed between the punching trigger 121 and the docking trigger 122. The third pressing plate 62 is installed on the upper end of the movable sleeve 61, and a plurality of plate hole grooves 621 are evenly provided on the third pressing plate 62. The edge of the third pressing plate 62 is provided with a bending portion extending downward to match the bent plate to achieve the fitting setting of the bent plate and the surface of the third pressing plate 62. The positioning groove 63 is provided on both sides of the third pressing plate 62, and a sliding groove 631 is provided in the positioning grooves 63 on both sides near the wall of the third pressing plate 62.

The pressing trigger assembly 65 is installed on the side wall end of the third pressing plate 61, and the pressing trigger assembly 65 is located near the edge of the fixed pressing assembly 4, so that when the bent sheet enters the limiting baffle 643, the pressing trigger assembly 65 is triggered. The pressing trigger assembly 65 includes a rotating portion 651, a pressing rod 652, a first spring 653 and a sliding trigger member 654.

Among them, the first spring 653 is arranged in the pressing rod 652 and the third pressing plate 61. In the normal state, the first spring 653 supports the pressing rod 652 to maintain an inclined state protruding from the side wall end of the third pressing plate 61. The sliding trigger member 654 is arranged on one side of the first spring 653. When the bent plate enters the limiting baffle 643, it presses the pressing rod 652 to press the sliding trigger member 654. The sliding trigger 654 is electrically connected to the sliding drive. When the sliding trigger 654 is pressed, a signal is sent to control the movement of the positioning slider 641 through the sliding drive. At the same time, the sliding trigger 654 is also electrically connected to the driving end of the suction nozzle 642 to maintain the attraction and fixation of the bent sheet when moving. It should be noted that the above steps are linked when the moving sleeve 61 triggers the docking trigger 122.When the contact trigger 122 controls the boosting component 5 to push the bent sheet, the bent sheet at the non-boosting end enters the limiting baffle 643, and at the same time, it presses against the pressing trigger component 65 to realize the attraction, fixation and movement of the positioning slider 641 on the bent sheet, so as to move the whole bent sheet from one end of the plate hole pressing component 6 to the other end, and place the sheet body of the sheet on the third pressing plate 62.

[0027] Specifically, the punching component 7 is located above the plate hole pressing component 6 in the X-axis direction.

[0029] Embodiment 2:

[0030] Please refer to Figures 10-11 , an intelligent continuous type ring main unit sheet metal forming equipment. Different from Embodiment 1, a starting trigger groove 231 is arranged on the positioning plate 23 in the X-axis direction, and a starting component 26 is embedded in the starting trigger groove 231.

The housing 241 is a hollow housing, and the housing 241 is disposed on the positioning plate 23. The hollow telescopic rod 242 is placed inside the housing 241 and extends into the upper end wall of the first pressing plate 22. The second spring 243 is sleeved on the hollow telescopic rod 242, and one end of the second spring 243 is fixedly connected to the upper end inside the housing 241, and the other end of the second spring 243 is fixedly connected to the first electromagnet 244. Among them, wires are arranged inside the hollow telescopic rod 242 to electrically connect the first electromagnet 244 to the power supply component 247. The magnetic conductive housing 245 is wrapped around the outer periphery of the first electromagnet 244, and the magnetic conductive housing 245 is in interference fit with the first electromagnet 244, so that the magnetic conductive housing 245 is tightly arranged on the outer periphery of the first electromagnet 244. The non-magnetic conductive layer 246 is disposed at the lower end of the magnetic conductive housing 245, and the non-magnetic conductive layer 246 is fixedly connected to the magnetic conductive housing 245.

Among them, a second electromagnet 251 is arranged inside the lower clamping mechanism 25. It should be noted here that the adjacent magnetic poles of the first electromagnet 244 and the second electromagnet 251 are opposite. For example, if the first electromagnet 244 is an N pole, the second electromagnet 251 is an S pole, and vice versa. When the first electromagnet 244 and the second electromagnet 251 are energized, the first electromagnet 244 and the second electromagnet 251 attract each other to achieve the clamping function; when the first electromagnet 244 and the second electromagnet 251 are de-energized, the magnetism disappears and the clamping function is lost.

[0033] Specifically, the starting component 26 includes a metal slider, a third spring 261, and a metal contact 262. One end of the third spring 261 is fixed to the bottom end of the starting trigger groove 231, and the other end of the third spring 261 is fixedly connected to the metal slider. In the normal state, the third spring 261 supports the metal slider to protrude from the starting trigger groove 231. Among them, there is also a circuit system, which includes a metal slider, a metal contact 262, and an electrical signal generator, connected in series in sequence. It should be noted here that when the plate is abutted against the first pressing plate 22 and pushed into the positioning plate to squeeze the starting component 26, the metal slider is pressed to touch the metal contact 262 to connect the circuit system, and then the electrical signal generator emits a signal. The electrical signal generator is electrically connected to the power supply component 247 to enable the starting component 26 to control the clamping start and stop of the upper clamping component 24 and the lower clamping component 25.

[0034] Working principle: When the plate is pressed into the positioning plate of the movable pressing component, the metal slider in the starting component is pressed to contact the metal contact to form a circuit, so that the magnetic shell of the upper clamping mechanism and the opposite-polar electromagnet of the lower clamping mechanism generate strong magnetic attraction to clamp the plate; when the movable pressing component carries the plate to the end of the X-axis, the clamping power-off trigger is triggered. After the electromagnet is powered off, the non-magnetic layer eliminates the residual magnetism, and the second spring resets to separate and release the clamping mechanism; the plate transferred to the fixed pressing component is pressed to trigger the clamping trigger, and the clamping plate extends out to cooperate with the bending limit plate to complete the bending and shaping, and then the booster component is linked to push the plate into the positioning slider area of the plate hole pressing component, and the pressing rod is squeezed by the plate to trigger the sliding trigger, and the vacuum nozzle adsorbs the plate and accurately positions it along the slide groove to the punching station to complete the processing.
