Description

Technical Field

[0001] The present invention relates to the technical field of steel plate processing, and in particular to a device for integrated cutting and punching processing of steel plates for a box body of a box-type substation and a processing method thereof. Background Art

[0002] Heat dissipation holes need to be processed on the steel plates used for the box body of the box-type substation. Currently, when processing steel plates, most of them are evenly cut into standard parts of the same size, and then the cut steel plates are placed in a punching machine to punch several steel plates one by one. This is inefficient and the punching positioning is inconvenient. It may also require manual auxiliary operations, which is less convenient.

[0003] Therefore, the patent application number CN202411033074.5 proposes a steel plate cutting and punching integrated machine for the production of distribution cabinets. When processing the steel plate, it rotates by manipulating a number of feed rollers, thereby driving the steel plate to move and move it to the inside of the processing box. Then, the punching component and the cutting component can be used in the processing box to punch and cut the steel plate respectively, which is very convenient. After the processing of the steel plate is completed, the steel plate can be moved to the transport platform for transportation. When processing the steel plate, as the steel plate moves to the position of the pressing frame, the pressing part can be manipulated. Move in the direction close to the steel plate to press the steel plate, and then the punching machine can be operated to punch the steel plate; then the feed roller can be operated to transport the steel plate and move the steel plate to the pressing plate. At this time, the pressing part is operated downward again, and the pressing plate and the pressing frame both press the steel plate. At this time, the punching part is operated to punch the steel plate, and the laser cutting part is operated to cut the steel plate at the same time, thereby improving the processing efficiency of the steel plate. After the steel plate is cut, the above steps are repeated again. At this time, the cut steel plate moves under the push of the subsequent steel plate, and the efficiency of steel plate processing is higher.

[0004] It is only compressed by the pressing plate, but the steel plate itself may also have a certain degree of bending. It cannot solve the problem of its own bending, nor can it ensure that no stamping bending occurs. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides an integrated cutting and punching processing device for the box body steel plate of a box-type substation and a processing method thereof, which solves the problem that the existing technology only relies on pressing plates for pressing. However, the steel plate itself may also have a certain degree of bending, which cannot solve the problem of its own bending and cannot ensure that the problem of stamping bending will not occur.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a box-type substation box steel plate cutting and punching integrated processing device, including a punching mechanism and a cutting mechanism, wherein the punching mechanism includes:

[0007] A punch seat, wherein a punch is provided at the lower end of the punch seat;

[0008] There are two sets of pressing wheels, which are located just below the punch. The pressing wheels are assembled on the wheel seat. The end of the wheel seat is provided with a pressing rod, and the two pressing rods on the same side are cross-arranged;

[0009] The pressing assembly is arranged on both sides of the punch seat and is used to apply pressure to the upper end of the pressing rod. The pressing assembly also includes an acceleration structure, a deceleration structure and a stop structure, so that the movement state of the lower end of the pressing rod changes to: quickly pushing the pressing wheel, slowly pushing the pressing wheel and stopping pushing the pressing wheel, forming three states in which the pressing wheel quickly applies rolling pressure to the steel plate and leaves the area directly below the punch, slows down after leaving the area directly below the punch, and presses the workpiece on both sides of the area directly below the punch.

[0010] Furthermore, it also includes an assembly box, wherein the punch seat is located in the assembly box;

[0011] Both sides of the punch seat are provided with side wings, and one side of the side wing is fixedly provided with a guide platform;

[0012] The assembly box is provided with a pressing component, and the pressing component comprises:

[0019] The spiral rise angle of spiral groove two is greater than that of spiral groove one, and the spiral rise angle of spiral groove three is less than that of spiral groove one. The total height of spiral groove two, spiral groove three and arc groove is equal to the total height of spiral groove one, so that during the downward punching of the punch seat and the punch, the pressure rod quickly separates from the area directly below the punch, slowly moves from the areas on both sides below the punch, and presses the periphery of the area to be cut in a fixed state.

[0020] Furthermore, a guide rod assembly is also included, and the guide rod assembly includes:

[0021] A guide rod body, wherein the guide rod body is located on the moving path of the wheel seat, and the end of the wheel seat is sleeved on the guide rod body;

[0022] A carrier, the carrier being fixedly mounted at both ends of the guide rod body;

[0023] Spring 1, the spring 1 is installed between the carrier and the guide platform, so that the guide platform will not push the carrier downward when the punch seat moves downward to punch;

[0024] The Z-axis guide column is sleeved inside the spring 1, the lower end of the Z-axis guide column is fixed on the carrier, and the other end passes through the guide platform and is fixed with a limit plate.

[0025] Furthermore, the pressing wheel is an expandable structure, and the pressing wheel gradually expands when it moves slowly to apply further pressure to the steel plate;

[0026] Also included is a power assembly, the power assembly comprising:

[0027] Gear 1, said gear 1 being fixed on the central axis of the pressing wheel;

[0028] The tooth seat is fixed on the side of the carrier close to the guide rod body. A tooth portion that can adapt to gear one is provided below the tooth seat, so that the central axis can rotate when the pressure wheel reaches the position of the tooth portion. The rotational torque of the central axis serves as the power for the expansion of the pressure wheel.

[0029] Furthermore, the pressing wheel includes:

[0030] an inner cylinder, said inner cylinder being located outside the central axis;

[0031] Arc plates, wherein at least four groups of the arc plates are provided and enclose a full circle, a guide shaft is fixedly provided on the inner side of the arc plates along the radial direction, the guide shaft passes through the inner cylinder and contacts the central axis, and a protrusion is fixedly provided on the outer periphery of the central axis;

[0032] Spring 2 is installed between the inner wall of the inner cylinder and the end of the guide shaft close to the protrusion.

[0033] Furthermore, slide grooves are provided on both sides of the punch seat, a main rail is fixed in the assembly box, the main rail is adapted to the slide groove, and a punching power head for driving the punch seat to rise and fall is installed in the assembly box.

[0034] Furthermore, it also includes a feeding machine, wherein the feeding machine is provided with a gantry frame 1 which is movable along its conveying direction, and the assembly box can slide along the gantry frame 1;

[0035] The feeding machine is provided with a second gantry which is movable along its conveying direction, and a laser cutting head is slidably mounted on the second gantry.

[0036] A loading roller is provided above the feeding machine at one end close to the gantry, for conveying the steel plate to the bottom of the punch.

[0037] Furthermore, the area on the feeding machine tool opposite to the punch has an empty area, and a punching station is provided in the empty area.

[0038] On the other hand, the present invention also provides a method for integrated cutting and punching of steel plates for a box-type substation, which is applicable to the above-mentioned integrated cutting and punching device for a box-type substation, and comprises the following steps:

[0039] Step 1: Use the feeding machine and the loading roller to transport the steel plate to the bottom of the gantry 1, and use the punch to punch it. During the punching action, the pressure wheel flattens the steel plate directly under the punch in a rolling posture, and expands after leaving the steel plate directly under the punch, thereby applying further pressure to the steel plates on both sides below the punch;

[0040] Step 2: The punched steel plate is transported by the feeding machine to the bottom of the laser cutting head for laser cutting.

[0041] The present invention has the following beneficial effects:

[0042] (1) The integrated processing device for cutting and punching steel plates of the box-type substation and its processing method can apply pressure to the upper end of the pressure rod when the punch seat and the punch move downward to punch the steel plate, so that the lower end of the pressure rod applies rolling pressure to the steel plate through the pressure wheel until the pressure wheel leaves the area directly below the punch. This rolling pressure can make the steel plate in the area to be punched smoother, and when the punch forms a hole in the steel plate, the pressure wheel can also provide pressure on the steel plate to avoid bending and deformation of the steel plate.

[0043] (2) The integrated cutting and punching processing device and processing method for the box-type substation box steel plate can ensure that the pressure wheel quickly separates from the bottom of the punch due to the setting of the speed change groove, and can ensure that it moves slowly after separation, ultimately achieving the purpose of fixed-point pressure, ensuring cutting stability, and avoiding bending and deformation of the steel plate.

[0044] (3) The integrated cutting and punching processing device for the box-type substation box steel plate and its processing method are provided with an expandable pressure wheel, which can increase the pressure on the steel plate during the fixed-point pressure application stage, thereby further improving the stamping stability of the steel plate and avoiding bending.

[0045] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0065] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0066] The following is based on Figures 1-17 The present invention provides a box-type substation box body steel plate cutting and punching integrated processing device and processing method thereof.

[0067] On the one hand, the present invention provides a box-type substation box body steel plate cutting and punching integrated processing device.

[0068] See also Figure 1As shown, an embodiment of the present invention provides a technical solution: a box-type substation box body steel plate cutting and punching integrated processing device, including a punching mechanism, a cutting mechanism and a feeding machine tool 1.

[0069] The cutting mechanism includes a gantry 14 and a laser cutting head 13 that can slide on the gantry 14 . Power rails for driving the gantry 14 to move are provided on both sides of the feeding machine 1 .

[0070] The punching mechanism includes a gantry 8, which is movable along the conveying direction of the feeding machine 1. The assembly box 16 can slide along the gantry 8. A punch 3 capable of punching holes is provided below the assembly box 16. A loading roller 2 is provided above the feeding machine 1 near the end of the gantry 8 for conveying the steel plate to the bottom.

[0071] Preferably, an area on the feeding machine 1 opposite to the punch 3 has an empty area, and a punching station is provided in the empty area.

[0072] Combine Figure 2-Figure 5 As shown, the punching mechanism also includes a punch seat 4, which is also located in the assembly box 16. The punch seat 4 is installed above the punch 3. A punching power head 15 is also provided inside the assembly box 16. The punching power head 15 can push or pull the punch seat 4 when working, so that the punch 3 moves down to punch or moves up to separate from the steel plate.

[0073] Preferably, slide grooves are provided on both sides of the punch seat 4, a main rail 10 is fixed in the assembly box 16, the main rail 10 is adapted to the slide groove, and a punching power head 15 for driving the punch seat 4 to rise and fall is installed in the assembly box 16; optionally, the punching power head 15 here can be a cylinder, a hydraulic cylinder or a mechanical stamping structure.

[0074] The above-mentioned pressing wheel 6 is provided with two groups. Before punching starts (when the punching power head 15 does not provide downward power to the punch seat 4), the pressing wheel 6 is located directly below the punch 3 (such as Figure 3 The upper end of the pressure rod 12 can be lowered by the power when the punch seat 4 and the punch 3 move downward, that is, when the punch seat 4 and the punch 3 move downward to punch the steel plate, pressure can be applied to the upper end of the pressure rod 12, so that the lower end of the pressure rod 12 applies rolling pressure to the steel plate through the pressure wheel 6 until the pressure wheel 6 is separated from the area directly below the punch 3. This rolling pressure can make the steel plate in the area to be punched smoother, and when the punch 3 forms a hole in the steel plate, the pressure wheel 6 can also provide pressure on the steel plate to avoid bending and deformation of the steel plate.

[0075] Combine Figure 5-Figure 8As shown, since the punch 3 descends at a relatively fast speed during the punching process, and the punch 3 cannot be too far away from the steel plate when not punching, in order to prevent the punch 3 from actually contacting the steel plate to punch the steel plate before the pressing wheel 6 reaches the lower and side areas of the punch 3 (i.e., to prevent the pressing wheel 6 from blocking the punch 3 from punching), Figure 2-Figure 4 As shown, a pressing component 9 is also provided here, and the pressing component 9 also includes an acceleration structure, a deceleration structure and a stop structure, so that the moving state of the lower end of the pressing rod 12 changes to: quickly pushing the pressing wheel 6, slowly pushing the pressing wheel 6 and stopping pushing the pressing wheel 6, forming three states and a stop structure in which the pressing wheel 6 quickly applies rolling pressure to the steel plate and leaves the area directly below the punch 3, decelerates after leaving the area directly below the punch 3, and presses the workpiece on both sides of the area directly below the punch 3. The pressing wheel 6 quickly applies rolling pressure to the steel plate and leaves the area directly below the punch 3 to avoid the pressing wheel 6 blocking the punch 3 from moving downward.

[0076] In order to facilitate the action of the pressing assembly 9, there are side wings 41 on both sides of the punch seat 4, and a guide platform 42 is fixed on one side of the side wing 41. The pressing assembly 9 is installed in the assembly box 16. The pressing assembly 9 includes an assembly seat 95, a guide component 93, a cylinder 92 and a gear 96. The assembly seat 95 is located on the side of the guide platform 42 close to the punch seat 4, and the side of the assembly seat 95 close to the guide platform 42 is assembled with a cylinder 91 through a bearing. The outer periphery of the cylinder 91 is provided with a spiral groove 911, and one side of the guide platform 42 is fixed with a spiral groove 911. 11 is adapted to the slider 97. When the punch 3 starts to move downward, the guide platform 42 will also move downward. Its downward movement will push the cylinder 91 to rotate through the movement of the slider 97 in the spiral groove 911. The guide component 93 is also installed on the assembly seat 95 and is close to the pressure rod 12. A slidable slide 94 is provided on the guide component 93. The slide 94 is hinged to the upper end of the pressure rod 12, so that when the slide 94 is under pressure, it can press the upper end of the pressure rod 12 downward to make the lower end of the pressure rod 12 expand outward, so that the pressure wheel 6 can apply rolling pressure to the steel plate.

[0077] The above-mentioned cylinder body 2 92 is located between cylinder body 1 91 and guide component 93, and gear 2 96 is installed at the upper ends of cylinder body 1 91 and cylinder body 2 92, and is used to make cylinder body 1 91 and cylinder body 2 92 rotate at the same speed. A speed regulating groove is provided on cylinder body 2 92, and a slider 2 98 is fixed on the slide seat 94. Slider 2 98 is adapted to the speed regulating groove. When cylinder body 2 92 rotates, slider 2 98 can be pushed downward through the speed regulating groove. The speed regulating groove here can drive the speed of slider 2 98 to change to fast, slow and stop.

[0078] Specifically: ① Fast: the upper end of the pressure rod 12 moves downward quickly, so that the pressure rod 12 can quickly push the lower end of the pressure wheel 6 out of the bottom of the punch 3; ② Slow: the upper end of the pressure rod 12 moves downward slowly, so that the pressure rod 12 can move slowly on both sides of the punch 3 to avoid it moving away from the area to be punched of the steel plate; ③ Stop: the upper end of the pressure rod 12 stops moving downward, and the punch 3 no longer moves on both sides of the area to be punched of the steel plate, and it is punched and positioned to avoid local bending of the steel plate.

[0079] Combine Figures 9-13 As shown, specifically, the speed regulating groove includes a spiral groove 2 921 as an acceleration structure, a spiral groove 3 922 as a deceleration structure, and an arc groove 923 as a stop structure, which are arranged in sequence from top to bottom. The spiral rise angle of the spiral groove 2 921 is greater than the spiral groove 1 911, so that when the rotation speed of the cylinder 1 91 and the cylinder 2 92 is the same, the downward movement speed of the slider 2 98 is greater than the downward movement speed of the slider 1 97, that is, the downward movement speed of the punch 3 is less than the downward movement speed of the pressure wheel 6, and the spiral rise angle of the spiral groove 3 922 is less than the spiral groove 1 911. When the slider 2 98 reaches the junction of the spiral groove 2 921 and the spiral groove 3 922, the pressure wheel 6 has completely left the bottom of the punch 3 (refer to Figure 12 ); When the slider 2 98 is at the position of the spiral groove 3 922, its downward moving speed is greatly reduced. When the slider 2 98 slides in the arc groove 923, the slider 2 98 no longer moves, that is, the pressure wheel 6 applies a fixed point pressure to the steel plate; so that during the downward punching process of the punch seat 4 and the punch 3, the pressure rod 12 quickly breaks away from the area directly below the punch 3, slowly moves from the areas on both sides below the punch 3, and presses the periphery of the area to be cut in a fixed state.

[0080] The total height of the second spiral groove 921 , the third spiral groove 922 , and the arc groove 923 is equal to the total height of the first spiral groove 911 .

[0081] Reference Figure 3 and Figure 6 As shown, in order to ensure the stable movement of the pressure wheel 6, a guide rod assembly 5 is also provided here. The guide rod assembly 5 includes a guide rod body 55. The guide rod body 55 is located on the moving path of the wheel seat 11. The end of the wheel seat 11 is sleeved on the guide rod body 55, thereby ensuring the horizontal movement of the pressure wheel 6.

[0082] In order to fix the position of the guide rod body 55, a carrier 51, a spring 52 and a Z-axis guide column 53 are also provided here. The carrier 51 is fixed at both ends of the guide rod body 55, and the spring 52 is installed between the carrier 51 and the guide platform 42, so that the guide platform 42 will not push the carrier 51 to move down when the punch seat 4 moves down to punch a hole. The Z-axis guide column 53 is sleeved inside the spring 52, and the lower end of the Z-axis guide column 53 is fixed on the carrier 51, and the other end passes through the guide platform 42 and is fixed with a limit plate 54.

[0083] Therefore, when the punching action is performed, the downward movement of the punch seat 4 can drive the entire guide platform 42 to move downward, so that the guide platform 42 can press down the spring 1 52 without causing the carrier 51 to move downward.

[0084] In order to ensure the pressing force of the pressing wheel 6 when pressing the steel plate at a fixed point, the pressing wheel 6 here is an expandable structure. The pressing wheel 6 gradually expands when moving slowly to apply further pressure to the steel plate.

[0085] like Figure 7 In order to achieve the gradual expansion of the pressure wheel 6 when it moves slowly, a power component 7 is also provided here. The power component 7 includes a gear 1 71 and a tooth seat 72. The gear 1 71 is fixed on the central axis 62 of the pressure wheel 6, and the tooth seat 72 is fixed on the side of the carrier 51 close to the guide rod body 55. A tooth portion 73 that can adapt to the gear 1 71 is provided below the tooth seat 72, so that the central axis 62 of the pressure wheel 6 can rotate when the pressure wheel 6 reaches the position of the tooth portion 73, and the rotational torque of the central axis 62 serves as the power for the expansion of the pressure wheel 6.

[0086] In this embodiment, when the slider 2 98 moves in the spiral groove 3 922, the pressure wheel 6 moves slowly, and the gear 1 71 engages with the tooth portion 73 to rotate the central axis 62. In fact, it cannot rotate greatly, or the central axis 62 can only have a certain rotation tendency. This is because the pressure wheel 6 is blocked by the steel plate below, which causes the pressure wheel 6 to only expand slightly. The expansion can increase the pressure on the steel plate and improve the stability of the area to be punched when the steel plate is punched. When the slider 2 98 reaches the arc groove 923, the pressure wheel 6 is pressed against the steel plate in an expanded posture.

[0087] Combine Figure 14-17 As shown, the pressure wheel 6 mentioned above includes an inner cylinder 64, an arc plate 61 and a second spring 66. The inner cylinder 64 is located outside the central axis 62. There are at least four groups of arc plates 61 (six groups are shown in the figure) and they enclose a whole circle. A guide shaft 65 is fixedly provided on the inner side of the arc plate 61 along the radial direction. The guide shaft 65 passes through the inner cylinder 64 and contacts the central axis 62. A protrusion 63 is fixedly provided on the outer periphery of the central axis 62. The second spring 66 is installed between the inner wall of the inner cylinder 64 and the end of the guide shaft 65 close to the protrusion 63.

[0088] In this embodiment, when the middle shaft 62 rotates, it can drive the protrusion 63 to rotate, and then the protrusion 63 will generate a thrust on the guide shaft 65, so that the guide shaft 65 can push the arc plates 61, causing each arc plate 61 to expand, thereby achieving the expansion of the entire pressure wheel 6.

[0089] When in use (working), the steel plate rolled into a coil is transported to the feeding machine 1 through the feeding roller 2 and reaches the punching mechanism. The punching mechanism first pushes the punch seat 4 downward through the punching power head 15. When the punch seat 4 moves downward, it drives the guide platform 42 downward through the side wing 41. The downward movement of the guide platform 42 can drive the slider 1 97 to move downward. The slider 1 97 can drive the cylinder 1 91 to rotate through the spiral groove 1 911, so that the cylinder 1 91 can drive the cylinder 2 92 to rotate through the gear 2 96. The cylinder 2 92 can push the slider 2 98 downward through the spiral groove 2 921. The downward movement of the slider 2 98 can drive the slide 94 to move downward quickly. The slide 94 can quickly push the upper end of the pressure rod 12 downward, so that the pressure wheel 6 moves quickly to both sides and out of the area directly below the punch 3. When the slider 2 98 reaches the intersection of the spiral groove 2 921 and the spiral groove 3 922, the pressure wheel 6 has completely left the area directly below the punch 3 (refer to Figure 12 ); When the slider 2 98 is at the position of the spiral groove 3 922, its downward movement speed is greatly reduced. At the same time, the gear 1 71 engages with the tooth portion 73 to rotate the middle shaft 62 (in fact, it cannot rotate greatly, or the middle shaft 62 can only have a certain rotation trend. This is because the obstruction of the steel plate below causes the pressure wheel 6 to only expand slightly, and its expansion can increase the pressure on the steel plate). When the middle shaft 62 rotates, it can drive the protrusion 63 to rotate, and then the protrusion 63 will generate a thrust on the guide shaft 65, so that the guide shaft 65 can push the arc plate 61, so that each arc plate 61 expands, thereby realizing the expansion of the entire pressure wheel 6. When the slider 2 98 reaches the arc groove 923, the pressure wheel 6 is pressed against the steel plate in an expanded posture. The expansion of the pressure wheel 6 can increase the pressure on the area to be punched in the steel plate when punching the steel plate, thereby improving the stability of the area to be punched.

[0090] After the cutting of a single position is completed, the remaining areas of the steel plate can be punched by sliding the assembly box 16 on the gantry 8. The punched steel plate can be transported by the feeding machine 1 to the position of the laser cutting head 13 for cutting.

[0091] On the other hand, the present invention also provides a method for integrated cutting and punching of steel plates for a box-type substation, which is applicable to the above-mentioned integrated cutting and punching device for a box-type substation, and comprises the following steps:

[0092] Step 1: Use the feeding machine 1 and the loading roller 2 to transport the steel plate to the bottom of the gantry 8, and use the punch 3 to punch it. During the punch 3 punching the steel plate, the pressure wheel 6 flattens the steel plate directly under the punch 3 in a rolling posture, and expands after leaving the steel plate directly under the punch 3, so as to apply further pressure to the steel plates on both sides below the punch 3;

[0093] Step 2: The punched steel plate is transported by the feeding machine 1 to the bottom of the laser cutting head 13 for laser cutting.
