Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal cutting, and particularly discloses a power distribution cabinet assembly positioning and cutting device. BACKGROUND

[0002] The copper bar is also called copper busbar or copper busbar, which is a long conductor made of high-purity red copper and has a rectangular or rounded rectangular cross section. In a power distribution cabinet, the copper bar is a key component for transmitting and distributing electric energy, mainly serving as a primary line and bearing the important task of transmitting current and connecting electrical equipment. Copper bar cutting is a key process in copper bar processing, which needs to ensure the dimensional accuracy and better connection effect. The cutting section needs to be flat, without burrs, obvious depressions or protrusions, otherwise it will increase the contact resistance or scratch the insulation, affecting the current transmission.

[0003] In order to ensure the cutting efficiency of the copper bar, the copper bars are stacked and cut by one cutter during cutting. At this time, the cutter continuously cuts a large amount of metal material in a short time, which generates a lot of heat. High temperature not only accelerates the wear of the cutter, but also causes the cutting quality to deteriorate. At the same time, the heat is conducted to the copper bar, which causes the copper bar to work hardening or annealing softening, changing the mechanical properties of the copper bar. Since the multiple copper bars are closely connected, the burrs generated during cutting are easy to stick to each other, and even the burrs can be embedded in the surface of the adjacent copper bar, causing the cutting surface to produce depressions or protrusions. In addition, the debris generated during cutting also easily causes abrasion to the copper bar, affecting the quality of the copper bar.

[0004] Therefore, there is an urgent need for a power distribution cabinet assembly positioning and cutting device that can prevent the heat generated during cutting from affecting the performance of the copper bar and prevent the burrs generated from sticking or embedding in the adjacent copper bar, thereby affecting the current transmission of the copper bar.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] In order to make the person in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0031] As Figures 1-3 and Figures 7-10As shown, a power distribution cabinet assembly positioning cutting device is disclosed, which is designed to cut the copper bars in the power distribution cabinet to a fixed length, comprising a workbench 1 and a support frame 2, a plurality of copper bars are arranged in a rectangular shape and pass through the inside of the support frame 2, the copper bars are inserted into the inside of the support frame 2, and each copper bar is separated by a baffle in the support frame 2, at this time the burrs generated on the surface of the adjacent copper bars can be effectively prevented from sticking or embedding in the copper bar when the cutter is cutting, thereby ensuring the conductivity of the copper bar itself. In order to cut the copper bars to a fixed length, the support frame 2 is needed to clamp and feed the copper bars, and the support frame 2 is located at the tail position of the copper bars during installation, so as to continuously feed the copper bars.

[0032] The inside of the support frame 2 is adhesively connected with a clamping sleeve 8, which is made of rubber. When the copper bar passes through the inside of the clamping sleeve 8, the clamping sleeve 8 tightly wraps around the surface of the copper bar. The lower surface of the support frame 2 is fixedly assembled with two symmetrical electric sliding blocks 9. The surface of the workbench 1 is provided with a corresponding sliding groove 10. The electric sliding block 9 slides in the sliding groove 10. When the electric sliding block 9 slides, it can drive the support frame 2 to move while clamping the copper bar. The moving path is the length that needs to be cut. It needs to be noted that the length, width and height of the copper bar are different, and the size of the support frame 2 required is also different. The main purpose is to clamp the copper bar and move stably.

[0033] The surface of the workbench 1 is fixedly assembled with two auxiliary frames 3, which are mainly used in cooperation with the support frame 2 to make the copper bar in a completely horizontal state. A gap is provided between the two auxiliary frames 3, which is the position that needs to be cut. The auxiliary frame 3 and the support frame 2 need to be replaced for different sizes of copper bars. The auxiliary frame 3 includes a U-shaped frame 31 for placing the copper bar. The surface of the U-shaped frame 31 is slidably assembled with a placement frame 32 for separating the copper bars. The length of the placement frame 32 is greater than that of the U-shaped frame 31. The placement frame 32 includes an outer frame and transversely and longitudinally staggered partition plates. The inside of the partition plate is provided with a hollow. The surface of the vertical partition plate and the horizontal partition plate is movably installed with an extrusion plate 33. When the extrusion plate 33 moves, it can be close to or away from the surface of the copper bar, so as to Figure 9 and Figure 10For example, the copper bar in the middle position is pressed by the pressing plate 33 at the top and bottom positions, the copper bar in the top position is pressed by the pressing plate 33 at the bottom, and the copper bar in the bottom position is pressed by the pressing plate 33 at the top. The surface of the pressing plate 33 is provided with a connecting spring 34, and the connecting springs 34 of the top and bottom pressing plates 33 are mounted on the inner wall of the placing rack 32. The connecting springs 34 of adjacent pressing plates 33 are connected to the surface of the pressing plate 33. The inside of the placing rack 32 is slidably provided with a pressing block 35, which is wedge-shaped. When moving, the inclined surfaces on both sides will press the pressing plate 33, so that the pressing plate 33 is more closely attached to the surface of the copper bar. The pressing block 35 is fixedly connected by a moving frame 36, and the moving frame 36 itself has power to move.

[0034] As shown in the initial state Figure 2 , the copper bar is located in the inside of the auxiliary frame 3 and is in an unclamped state. When cutting is needed, the moving frame 36 moves to drive the pressing block 35 to move. When the pressing block 35 moves to a certain extent, the clamping force of the pressing plate 33 on the copper bar increases, and the placing rack 32 can move with the pressing block 35 to become Figure 3 state, providing stable support for the copper bar to ensure stability during cutting. When the copper bar is cut and generates burrs, the moving frame 36 moves back by a distance to drive the placing rack 32 to continuously move back until it moves back to the cutting position. When the moving frame 36 moves to the edge of the auxiliary frame 3, the edge of the auxiliary frame 3 will scrape off the protruding burrs to reduce the influence of the burrs on the conductivity of the copper bar.

[0035] As shown in Figures 1-4 , two auxiliary frames 3 are movably assembled with a cutting frame 4. The cutting frame 4 is provided with a cutter for cutting the copper bar. To ensure that the cutter can stably cut the copper bar, the movement of the cutting frame 4 is driven by a hydraulic rod (not shown in the figure). When the hydraulic rod drives the cutting frame 4 to move, the cutter continuously feeds to cut the copper bar. Since the cutter needs to continuously cut the copper bar at this time, it cannot be cooled in time. The cutting frame 4 is provided with a heat dissipation pipe 6, which is inclined towards the front end cutting position of the cutter. The heat dissipation pipe 6 continuously outputs cold air inside. At this time, not only can the cutter and the copper bar be cooled to improve the service life of the cutter and ensure the mechanical properties of the copper bar, but also the cold air blown out by the heat dissipation pipe 6 can carry away part of the debris generated during cutting, reducing the adhesion of debris on the cutter and affecting the cutting effect of the copper bar.

[0036] In the embodiment, the cutting frame 4 comprises a cutter frame 41 for mounting the cutter, and the cutter can move longitudinally away from the heat dissipation pipe 6, and the bottom frame 42 has a surface provided with a collecting groove 5 for collecting the scraps, and the inner wall of the collecting groove 5 is inclined to the middle position, when the scraps fall on the inclined surface of the collecting groove 5, they will slide along the inclined surface to the bottom of the collecting groove 5 and be accumulated, and it should be noted that the cold air output by the heat dissipation pipe 6 is stable and continuous, and the wind power is small, which can ensure the heat dissipation capacity and has a certain effect of blowing away the scraps on the cutter, and will not blow away the scraps in the collecting groove 5, and the size of the wind power output by the heat dissipation pipe 6 is obtained by the workers in the field through many tests.

[0037] As shown in Figures 4-6 The collecting groove 5 is internally slidably provided with a pushing block 13, the pushing block 13 is used for pushing the scraps in the collecting groove 5 to accumulate to a certain position for unified treatment, the shape of the pushing block 13 is matched with the shape of the inner wall of the collecting groove 5, so that it can be ensured that the pushing will not be missed, and the surface of the pushing block 13 is fixedly provided with two symmetrical electric sliding blocks 14, and the surface of the cutting frame 4 is correspondingly provided with two sliding grooves 15, and the electric sliding blocks 14 are slidably arranged in the sliding grooves 15, when the electric sliding blocks 14 move in the sliding grooves 15, they can drive the pushing block 13 to move and timely accumulate and treat the waste, so as to avoid that the waste falls on the surface of the copper bar and affects the cutting quality.

[0038] The pushing block 13 comprises a rectangular block 131 and a pushing plate 132, the rectangular block 131 is used for pushing the scraps in the middle of the collecting groove 5, and the pushing plate 132 is used for pushing the scraps on both sides of the inner wall of the collecting groove 5, and after the scraps on both sides are pushed and accumulated, they are more easily to slide from the inclined edge to the middle position of the collecting groove 5, in the embodiment, the thickness of the rectangular block 131 is greater than the thickness of the pushing plate 132, and the cutting frame 4 is provided with a discharge port 16 at the position corresponding to the collecting groove 5, at this time, the rectangular block 131 moves to the inside of the discharge port 16, and the scraps can be pushed out.

[0039] The upper surface of the pushing block 13 is fixedly provided with a mounting frame 17, and the surface of the mounting frame 17 is provided with a cleaning plate 7. In the embodiment, two groups of the cleaning plate 7 are provided, corresponding to the two auxiliary frames 3. At this time, the length of the cleaning plate 7 is greater than the height of the auxiliary frame 3. When the mounting frame 17 moves with the pushing block 13, the cleaning plate 7 can move with it. When moving through the auxiliary frame 3, the edge of the auxiliary frame 3 can be scraped to prevent burrs from affecting the subsequent feeding of the copper bar. In order to ensure more thorough scraping, the cleaning plate 7 is rotatably installed on the surface of the mounting frame 17 through a rotating shaft 11. The surface of the rotating shaft 11 is sleeved with a torsional spring 12. One end of the torsional spring 12 is fixed to the surface of the cleaning plate 7, and the other end of the torsional spring 12 is fixed to the surface of the mounting frame 17. The elastic force of the torsional spring 12 presses the cleaning plate 7 against the surface of the auxiliary frame 3, so that the cleaning plate 7 is more closely attached to the auxiliary frame 3. When the cleaning plate 7 moves with the pushing block 13, the cutter needs to move upwards to facilitate the cleaning plate 7 to pass through the two heat dissipation pipes 6, and at the same time, the gas inside the heat dissipation pipes 6 can remove the debris on the surface of the cleaning plate 7.

[0040] The cutting process is that the support frame 2 clamps multiple copper bars and moves a fixed distance, the cutting frame 4 moves to cut the copper bars, cold air is introduced into the two heat dissipation pipes 6 to cool the surface of the cutter and the cutting position of the copper bar, thereby prolonging the service life of the cutter and reducing the influence of high temperature on the mechanical properties of the copper bar itself. The debris falls into the collecting groove 5 below the cutting frame 4 under the action of its own gravity and the blowing force of the cold air.

[0041] The cleaning process is that the support frame 2 pushes the excess copper bar to move the cut copper bar until the end of the cut copper bar is flush with the edge of the corresponding auxiliary frame 3, and then the support frame 2 moves back to pull the excess copper bar to be flush with the edge of the corresponding auxiliary frame 3. In this process, the edge of the auxiliary frame 3 partially cleans the edge of the copper bar. Then the pushing block 13 moves to push the debris accumulated in the collecting groove 5, and the cleaning plate 7 is pressed against the edge surface of the auxiliary frame 3 and the cutting surface of the copper bar. In the moving process, the debris generated on the cutting surface is cleaned. When the pushing block 13 moves to the position below the heat dissipation pipes 6 again, the debris on the surface of the cleaning plate 7 is blown off. At the same time, the cleaning plate 7 is pressed into the two auxiliary frames 3 under the action of the torsional spring 12. When the cleaning plate 7 moves out of the two auxiliary frames 3, the rebound force of the torsional spring 12 will make the cleaning plate 7 vibrate, and part of the debris will also be shaken off. The rectangular block 131 on the pushing block 13 pushes the debris to the position of the discharge port 16.

[0042] The copper bar is cooled and the cuttings are blown away by the cooling pipe 6 during the cutting process, so that the first level of cutting is cleaned, the service life of the cutting tool and the copper bar is prolonged, and the surface of the copper bar is prevented from being scratched by the cuttings, so that the conductivity of the copper bar is ensured; after the cutting is completed, the auxiliary frame 3 moves to clean the edge surface of the copper bar; then the cleaning plate 7 can clean the edge surface of the auxiliary frame 3 and the cutting surface of the copper bar three times during the movement, so that the cleaning effect is further improved, and the cooling pipe 6 blows the surface of the cleaning plate 7 during the movement of the cleaning plate 7, so that the fourth level of cutting is cleaned, and the cuttings are collected through the collecting groove 5, so that the cutting quality of the copper bar is improved.
