Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and particularly to a cutting machine for charging pile metal brackets. Background Technique

[0002] The charging pile metal bracket is a metal structural member that supports and fixes the charging pile. It is the core basic component for the installation and deployment of the charging pile. It not only needs to bear the overall weight of the charging pile, but also needs to adapt to different installation scenarios, and at the same time provide wind resistance, earthquake resistance and corrosion protection capabilities to ensure the long-term stable operation of the charging pile. The cutting machine for the charging pile metal bracket is a device used to cut the materials of the charging pile metal bracket. As a type of cutting machine, the sawing machine mainly cuts the charging pile metal bracket through the mechanical cutting movement of the saw blade. By the friction and cutting of the saw teeth and the metal bracket material, the material is cut off. The sawing machine is suitable for cutting raw materials of metal brackets in various shapes and has certain advantages in cutting medium-thick plates and bars. The equipment cost is relatively low and the maintenance is relatively convenient.

[0003] Currently, since most of the metal brackets of charging piles are strip-shaped metal pipes with a cross-section in the shape of a hollow square, during the cutting process of the charging pile metal bracket using a sawing machine, local high temperature will be generated during the high-speed cutting of the saw blade, causing the metal pipe in the cutting area of the bracket to expand due to heat. However, due to the fast heat dissipation of the thin-walled part of the hollow square metal pipe and the slow heat dissipation of the thick-walled part, the metal after expansion contracts inconsistently when cooling, and thus an internal stress difference is formed inside the material, and finally it is manifested as slight deformation. Most of the existing sawing machines do not have the function of automatically correcting deformation. As a result, during the later process of using the metal pipe as a charging pile metal bracket, the deformed part of the bracket becomes a weak point in force. The originally evenly distributed weight will be concentrated in this part. After long-term use, cracks are likely to appear here due to fatigue stress, resulting in a reduction in the stability of the charging pile.

[0004] Therefore, we propose a cutting machine for charging pile metal brackets to solve the problems mentioned above. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-4 The present invention provides a technical solution: a charging pile metal bracket cutting and processing machine, wherein the positioning component 3 includes a support frame 301, the bottom of the support frame 301 is fixedly connected to the top of the saw frame 1, a servo motor 302 is fixedly installed on the outer surface of the support frame 301 by screws, the output end of the servo motor 302 is fixedly connected to a rotating shaft 303, the two ends of the rotating shaft 303 respectively movably pass through to the opposite outside of the support frame 301, two clamps 304 are fixedly sleeved on the outer surface of the rotating shaft 303, and cylinders 305 are provided on the outer surface of the two clamps 304, and a positioning plate 306 is fixedly installed on one end of each of the two cylinders 305.

[0032] In this embodiment, when it is necessary to cut the components of the charging pile metal bracket with a U-shaped cross-section, the first step is to use methods such as... Figure 2The metal component is placed between the two strip rods in the translation limiting mechanism 4 as shown, and the part to be cut is aligned with the saw blade body 206. After the saw blade body 206 is fixed in position, the servo motor 302 is started to drive the rotating shaft 303 to rotate, which in turn drives the two clamps 304 to rotate, thereby driving the two positioning plates 306 to rotate. When the two positioning plates 306 are rotated to be completely parallel to the top of the hollow metal tube, the servo motor 302 is turned off, and the two cylinders 305 are started to extend, thereby driving the two positioning plates 306 to move downward, thus fixing the metal tube to the top of the saw frame 1. Figure 4 As shown, the positioning plate 306 has multiple elastic protrusions on the surface that contacts the metal tube. The purpose is to ensure stable clamping of the metal tube. Since the metal tube is a hollow structure with a thin wall, the elastic protrusions can disperse the clamping force through their own slight deformation, transforming the concentrated pressure into multi-point uniform flexible pressure. This ensures sufficient clamping force while preventing deformation of the metal tube wall. By using two positioning plates 306 with multiple elastic components to position the metal tube, the metal tube is kept stable during subsequent cutting while also providing protection.

[0033] like Figures 1-2 and Figures 7-8As shown, a charging pile metal support cutting processing machine, including saw frame 1, the top of saw frame 1 is close to the side edge and is provided with cutting assembly 2, the top of saw frame 1 is close to the other side edge and is provided with positioning assembly 3, the top of saw frame 1 is provided with protection assembly 6 for supporting metal support, protection assembly 6 includes first sealing block 601 and second sealing block 613, the inner wall of first sealing block 601 is fixedly embedded with four output pipes 608, the inner wall of first sealing block 601 is movably embedded with gear ring 603 near the center, the outer surface of gear ring 603 is engagedly connected with four gears 602, the inner wall of four gears 602 is fixedly embedded with limiting rods 609, one end of four limiting rods 609 is fixedly installed with multi-stage electric telescopic rod 610, one end of four multi-stage electric telescopic rods 610 is provided with positioning plug 612, the outer surface of saw frame 1 is provided with heating assembly 5 for heating solid wax, heating assembly 5 includes sealed tank 501, heating wire 502 is arranged at the interlayer of sealed tank 501, high-temperature chamber 503 for storing inert gas is fixedly connected to the outer surface of sealed tank 501, protection assembly 6 further includes stepping motor 604, the output end of stepping motor 604 is fixed with connecting shaft 605, the outer surface of connecting shaft 605 is fixedly sleeved with positioning frame 606 near one end, one end of four output pipes 608 is fixedly communicated with corrugated pipe 607, one end of four multi-stage electric telescopic rods 610 is fixedly installed with jack rod 611, the outer surface of one side of second sealing block 613 is close to four edges and is provided with clamping groove 614, the outer surface of one side of second sealing block 613 is fixedly embedded with iron plate 615 near the center, the other side of second sealing block 613 is provided with pressure sensor 617 near the center, the outer surface of first sealing block 601 is close to the center and is provided with electromagnet 616, the outer surface of four gears 602 is rotatably connected with the inner wall of first sealing block 601, the outer surface of gear ring 603 is rotatably connected with the inner wall of first sealing block 601, the outer surface of stepping motor 604 is fixedly connected with the outer surface of first sealing block 601 through screws, the outer surface of positioning frame 606 is fixedly connected with the outer surface of gear ring 603, one end of four corrugated pipes 607 is fixedly communicated with four ends of multi-way pipe 506 respectively, one end of four output pipes 608 is fixedly penetrated to the outside of first sealing block 601, one end of four limiting rods 609 is movably penetrated to the outside of first sealing block 601, one end of four jack rods 611 is fixedly connected with the outer surface of four positioning plugs 612 respectively, four positioning plugs 612 correspond to four clamping grooves 614 respectively, the top of saw frame 1 is coupled with translation limiting mechanism 4, the opposite outer surfaces of first sealing block 601 are coupled with the inner wall of translation limiting mechanism 4.

[0034] In the embodiment, after the metal pipe is fixed by the positioning assembly 3, the translation limiting mechanism 4 can be started, wherein, as shown in the figure, Figure 2As shown, the translation limiting mechanism 4 consists of two strip-shaped mounting rods, a lead screw, a limiting tube, and a driving device. Its purpose is to limit the metal tube to the left and right while also driving the movement of the protective component 6. The translation limiting mechanism 4 drives the first sealing block 601 forward, thereby driving the four multi-stage electric telescopic rods 610 forward. During the movement of the first sealing block 601, all four bellows 607 are stretched. The movement of the multi-stage electric telescopic rods 610 then drives the second sealing block 613, located at the foremost end, to move forward and insert into the metal tube. Inside the metal tube, the outer diameters of the first sealing block 601 and the second sealing block 613 are matched with the inner diameter of the metal tube. When the outer surface of the first sealing block 601 is inserted into the inside of the metal tube, the four multi-stage electric telescopic rods 610 are activated to extend them, which drives the insertion rod 611 to move forward, thereby driving the four positioning plugs 612 to move forward, and then driving the second sealing block 613 to move forward until the second sealing block 613 and the first sealing block 601 are respectively set on both sides of the saw blade body 206. At this time, the sealing of the metal tube cutting part is completed.

[0035] like Figures 1-2 and Figures 5-8 As shown, a metal bracket cutting and processing machine for charging piles includes a saw frame 1. A cutting component 2 is provided on the top of the saw frame 1 near one side edge, and a positioning component 3 is provided on the top of the saw frame 1 near the other side edge. A protective component 6 for supporting the metal bracket is provided on the top of the saw frame 1. The protective component 6 includes a first sealing block 601 and a second sealing block 613. Four output pipes 608 are fixedly embedded in the inner wall of the first sealing block 601, and a toothed ring 603 is movably embedded in the inner wall of the first sealing block 601 near the center. The outer surface of the toothed ring 603... Four gears 602 are meshed together. Each of the four gears 602 has a limiting rod 609 fixedly embedded in its inner wall. Each of the four limiting rods 609 has a multi-stage electric telescopic rod 610 fixedly installed at one end. Each of the four multi-stage electric telescopic rods 610 has a positioning plug 612 at one end. The outer surface of the saw frame 1 is provided with a heating component 5 for heating solid wax. The heating component 5 includes a sealed can 501. A heating wire 502 is provided in the interlayer of the sealed can 501. A high-temperature chamber 503 for storing inert gas is fixedly connected to the outer surface of the sealed can 501.

[0036] In this embodiment, after the sealing of the metal pipe cutting part is completed, the heating wire 502 can be electrically connected to the external power supply to release heat outward. The heating wire 502 is a mature technology and will not be described in detail here. After the paraffin liquid in the sealing tank 501 is heated and liquefied, the paraffin is a mixture of various alkanes with a melting point range of 50-70°C. Below 50°C, the paraffin will gradually harden. After the paraffin is liquefied, the bidirectional pump 504 can be started to drive the drainage pipe 505 to extract the liquid paraffin from the inside of the sealing tank 501, so that the paraffin enters the inside of the four corrugated pipes 607 through the multi-way pipe 506, and then flows into the inside of the output pipe 608, and finally is introduced between the outer surfaces of the first sealing block 601 and the second sealing block 613 to fill the metal pipe. Until the pressure sensor 617 detects that the liquid paraffin has completely filled the inner wall of the metal pipe, the working principle of the pressure sensor 617 is a mature technology and will not be described in detail here. Due to the physical properties of paraffin and the high heat conduction capacity of the metal pipe, a closed loop of spontaneous heat dissipation and phase change solidification is formed, which can quickly conduct the heat of the paraffin to the environment, thereby realizing the rapid solidification of the paraffin. In addition, the stepping motor 604 can be started during the solidification of the paraffin to drive the connecting shaft 605 to rotate, thereby driving the positioning frame 606 to rotate, so that the gear ring 603 rotates to drive the four gears 602 to rotate, thereby driving the four limiting rods 609 to rotate, and finally driving the four positioning inserts 612 to rotate, until the four positioning inserts 612 are respectively rotated to positions corresponding to the maximum diameters of the four clamping grooves 614. The maximum diameter position of the clamping groove 614 matches the maximum outer diameter of the positioning insert 612. Then the four multi-stage electric telescopic rods 610 can be started again to shorten them, thereby driving the four jack rods 611 to move in the direction of the first sealing block 601, thereby moving the four positioning inserts 612 out of the inside of the four clamping grooves 614 and moving back to positions away from the saw blade body 206, that is, the filling of the inside of the metal pipe cutting position is realized. During the cutting of the metal pipe by the sawing machine later, the saw blade body 206 will contact the metal pipe to generate a cutting force. If the hollow part of the metal pipe is not rigid enough, especially for thin-walled metal pipes, it is easy to deform under the action of the cutting force. The filling of the solidified paraffin can enhance the rigidity of the metal pipe. The solidified paraffin is tightly attached to the inner wall of the metal pipe to form a whole. During the cutting process, the filling material can share part of the cutting force, making the metal pipe bear force more evenly and reducing deformation caused by excessive local stress. The problem of slight deformation of the hollow metal pipe with a cross-section in the shape of a Chinese character in the charging pile metal support during the cutting process by the sawing machine is solved.

[0037] As Figures 1-8As shown, a charging pile metal support cutting processing machine, including saw frame 1, the top of saw frame 1 is close to one side edge set cutting assembly 2, the top of saw frame 1 is close to the other side edge set positioning assembly 3, the top of saw frame 1 is set for supporting the metal support protection assembly 6, protection assembly 6 includes first sealing block 601 and second sealing block 613, the inner wall of first sealing block 601 is fixedly embedded with four output pipes 608, the inner wall of first sealing block 601 is movably embedded with a tooth ring 603 near the center, the outer surface of tooth ring 603 is engagedly connected with four gears 602, the inner wall of four gears 602 is fixedly embedded with a limiting rod 609, one end of four limiting rods 609 is fixedly installed with a multi-stage electric telescopic rod 610, one end of four multi-stage electric telescopic rods 610 is provided with a positioning plug-in 612, the outer surface of saw frame 1 is provided with a heating assembly 5 for heating solid wax, heating assembly 5 includes a sealed tank 501, the interlayer of sealed tank 501 is provided with a heating wire 502, the outer surface of sealed tank 501 is fixedly connected with a high temperature chamber 503 for storing inert gas, cutting assembly 2 includes a moving mechanism 201, the outer surface of moving mechanism 201 is fixedly connected with the top of saw frame 1 through screws, the outer surface of moving mechanism 201 is coupled with a rotating mechanism 202, the outer surface of rotating mechanism 202 is fixedly sleeved with a protective cover 203, the outer surface of protective cover 203 is fixedly installed with a driving motor 204 through screws, the output end of driving motor 204 is fixedly connected with a driving shaft 205, both ends of driving shaft 205 are movably penetrated to the opposite outer parts of protective cover 203, the outer surface of driving shaft 205 is fixedly sleeved with a saw blade body 206, the saw blade body 206 is arranged in the interior of protective cover 203.

[0038] In the embodiment, when the metal pipe inner wall is filled, first, the saw blade body 206 is moved to the specified position through the moving mechanism 201, wherein, as shown in Figure 1As shown, the moving mechanism 201 consists of a threaded rod, a driving device, and a limiting structure. This is a mature existing technology and will not be described in detail here. Then, through the cooperation between the rotating mechanism 202 and the driving motor 204, the driving rod saw blade body 206 rotates and moves downwards to cut the metal tube. After cutting, the electromagnet 616 is electrically connected to an external power source to generate a magnetic field that attracts the iron plate 615. Since solid paraffin does not possess magnetic shielding capabilities, it cannot prevent the magnetic field generated by the electromagnet 616 from passing through itself. Therefore, even with solid paraffin separating the electromagnet 616 and the iron plate 615, they can still generate attraction normally. Simultaneously, the translation limiting mechanism 4 is activated again, causing the first sealing block 601 and the second sealing block 613 to continue moving forward, so that the first sealing block 601 and the second sealing block 613 are inside the complete metal tube, thus allowing the solid paraffin to continue to be stored in the sealed space. Since the heating wire 502 heats both the sealed container 501 and the inert argon gas in the high-temperature chamber 503, at this time… Then, the one-way valve 508 can be opened, allowing the hot gas in the high-temperature chamber 503 to enter the interior of the multi-port pipe 506 through the gas pipe 507. Finally, it enters the space between the first sealing block 601 and the second sealing block 613 through the four output pipes 608, heating and liquefying the solidified paraffin. At the same time, the bidirectional pump 504 is restarted to draw liquid between the first sealing block 601 and the second sealing block 613, allowing the liquid paraffin to enter the interior of the multi-port pipe 506 through the four output pipes 608, and finally flow back through the drainage pipe 505 to... The internal components of the sealed tank 501 are recycled. When there is no more paraffin between the first sealing block 601 and the second sealing block 613, the bidirectional pump 504 can be turned off and the servo motor 302 can be started in reverse, so that both positioning plates 306 are rotated to a position away from the metal tube, thus realizing the recycling of paraffin. The bidirectional pump 504 is a pump that can deliver liquid in both directions and has forward and reverse functions. By changing the rotation direction of the drive shaft 205, the bidirectional flow of liquid can be realized, that is, the position of the suction port and the discharge port can be changed according to the needs.

[0039] The usage and working principle of this device: When it is necessary to cut components of a charging pile metal bracket with a U-shaped cross-section, firstly by... Figure 2The metal part is placed between the two bars in the translation limiting mechanism 4 in the shown manner, and the part to be cut is aligned with the saw blade body 206. After the position of the saw blade body 206 is fixed, the servo motor 302 is started to drive the rotating shaft 303 to rotate, thereby driving the two clamps 304 to rotate, and thereby driving the two positioning plates 306 to rotate. When the two positioning plates 306 are rotated to be completely parallel to the top of the hollow metal pipe, the servo motor 302 is turned off, and the two air cylinders 305 are started to extend, thereby driving the two positioning plates 306 to move downward, thereby fixing the metal pipe at the top of the saw frame 1. Then the translation limiting mechanism 4 is started to drive the first sealing block 601 to move forward, thereby driving the four multi-stage electric telescopic rods 610 to move forward. During the movement of the first sealing block 601, the four bellows 607 are stretched by being pulled, and the movement of the multi-stage electric telescopic rods 610 drives the second sealing block 613 arranged at the front end to move forward and insert into the inside of the metal pipe. The outer diameters of the first sealing block 601 and the second sealing block 613 match the inner diameter of the metal pipe. When the outer surface of the first sealing block 601 is inserted into the inside of the metal pipe, the four multi-stage electric telescopic rods 610 are started to extend, driving the jack rod 611 to move forward, thereby driving the four positioning inserts 612 to move forward, thereby driving the second sealing block 613 to move forward, until the second sealing block 613 and the first sealing block 601 are arranged on the two sides of the saw blade body 206. At this time, the sealing of the part to be cut of the metal pipe is completed. After the sealing of the cut part of the metal pipe is completed, the heating wire 502 is electrically connected with the external power supply to release heat outward. After the paraffin in the sealing tank 501 is heated and liquefied by the heating wire 502, the bidirectional pump 504 is started to drive the drainage pipe 505 to extract the liquid paraffin from the inside of the sealing tank 501, so that the paraffin enters the inside of the four bellows 607 through the multi-way pipe 506, and then flows into the inside of the output pipe 608, and finally enters between the outer surfaces of the first sealing block 601 and the second sealing block 613 to fill the inside of the metal pipe. Until the liquid paraffin completely fills the inner wall of the metal pipe at this section is detected by the pressure sensor 617. Due to the physical properties of the paraffin and the high heat conduction capacity of the metal pipe, a closed loop of spontaneous heat dissipation and phase change solidification is formed, which can quickly conduct the heat of the paraffin to the environment to realize the rapid solidification of the paraffin. In addition, the stepper motor 604 is started to drive the connecting shaft 605 to rotate, thereby driving the positioning frame 606 to rotate, thereby driving the gear ring 603 to rotate, thereby driving the four gears 602 to rotate, thereby driving the four limiting rods 609 to rotate, and finally driving the four positioning inserts 612 to rotate, until the four positioning inserts 612 are rotated to positions corresponding to the maximum diameters of the four clamping grooves 614. Then the four multi-stage electric telescopic rods 610 are started again to shorten,Thus drive four jack plug rod 611 to the direction of the first sealing block 601 respectively move, thus four positioning plug 612 respectively remove four card slot 614 inside, and move back to the position away from the saw blade body 206, realize the filling of the metal pipe cutting position inside, when the metal pipe inner wall filling is completed, first through the moving mechanism 201 the saw blade body 206 is moved to the specified position, then it can be through the cooperation between rotating mechanism 202 and drive motor 204, drive rod saw blade body 206 rotates and turns down, cut the metal pipe, when cutting is completed, the electromagnet 616 is electrically connected with external power supply, makes it produce magnetic field, adsorbs iron plate 615, at the same time, start the translation limiting mechanism 4 again, drive the first sealing block 601 and the second sealing block 613 continue to move forward, make the first sealing block 601 and the second sealing block 613 in the complete metal pipe, so that solid paraffin continues to be stored in the sealed space, since the heating wire 502 heats the inert gas argon in the high-temperature chamber 503 while heating the sealed tank 501, at this time, the one-way valve 508 can be opened, the hot gas in the high-temperature chamber 503 passes through the air pipe 507 and enters the inside of the multi-way pipe 506, finally through four output pipes 608 enters the inside between the first sealing block 601 and the second sealing block 613, heats and liquefies the solidified paraffin, at the same time, start the bidirectional pump 504 again, make it extract liquid between the first sealing block 601 and the second sealing block 613, make the liquid paraffin enter the inside of the multi-way pipe 506 through four output pipes 608, finally backflow to the inside of the sealed tank 501 through the drainage pipe 505 and be recycled, when there is no paraffin between the first sealing block 601 and the second sealing block 613, bidirectional pump 504 can be closed, reverse start servo motor 302, make two positioning plates 306 all rotate to the position away from the metal pipe, that is, the paraffin recycling is completed.
