Description

Technical Field

[0001] This invention relates to a cutting device for the rubber sheet of a multi-metal rod conductive bar. Background Technology

[0002] Busbars, as high-current conductive components, are widely used in power distribution, new energy, rail transportation, and industrial power distribution. To prevent short circuits and ensure electrical safety, the outer surface of busbars is usually covered with an insulating rubber layer. When connecting or processing busbars, the insulating rubber at the ends needs to be cut. The rubber layer is often quite thick locally and typically has high hardness at room temperature, making cutting difficult. Current technologies use laser cutting or electric cutting machines such as angle grinders to address this problem. However, while laser beam irradiation for ablation cutting offers high precision and automation, the high temperature generated by the laser can easily melt, carbonize, or even burn the insulating rubber, resulting in uneven cut surfaces and even charring. Electric cutting methods, on the other hand, generate significant noise and dust during the cutting process.

[0003] Existing cutting devices are mostly used for cutting conductive busbars with single metal rods. However, for conductive busbars with multiple metal rods, the cutting difficulty is much greater because, in addition to the outer rubber coating, there is also adhesive material between adjacent metal rods that needs to be cut. The aforementioned cutting methods have significant limitations when cutting the rubber coating of bimetallic rod conductive busbars, especially in effectively handling the adhesive material between the rods. Therefore, there is a lack of existing technology and an urgent need for a device and method specifically designed for the structural characteristics of multimetallic rod conductive busbars that can efficiently achieve high-quality rubber coating cutting with smooth, flat, and damage-free cuts. Summary of the Invention

[0004] The purpose of this invention is to provide a new multi-metal rod conductive strip rubber cutting device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: a multi-metal rod conductive busbar rubber cutting device, wherein the conductive busbar includes multiple metal rods arranged parallel to each other, and rubber covering the outer periphery of all the metal rods; the cutting device includes two moving components arranged opposite to each other along a first direction and capable of moving towards each other; each moving component includes: The cutting component includes a cutting portion that pierces the rubber sheet along the first direction, the cutting portion having a plurality of cutting portions spaced apart along a second direction, the second direction being perpendicular to the first direction, and a groove capable of accommodating a single metal rod being formed between any two adjacent cutting portions, the number of grooves on each cutting component being the same as the number of metal rods; A positioning element, wherein the cutting element is fixedly disposed on one side of the positioning element, and a positioning groove is formed on the positioning element; Heating element for heating the cut piece; Wherein, the sum of the lengths of the cutting portions on the two cutting pieces along the first direction is greater than the thickness of the rubber, a first cutting edge is formed on the sidewall of the groove, and a second cutting edge is provided on the end of the cutting portion away from the groove along the first direction. The first cutting edge and the second cutting edge are connected to form a cutting edge that is connected between two adjacent cutting portions and extends continuously. The cutting element has a cutting position. When it is in the cutting position, the conductive bar is inserted into the positioning groove. The blade edges of the first cutting edge on the two cutting elements overlap to form a circumferentially closed cutting body. The shape of the cutting body is consistent with the outer contour shape of the corresponding metal rod.

[0006] In some embodiments, the positioning member includes two limiting portions spaced apart along the second direction, with a positioning groove formed between the two limiting portions. The two limiting portions abut against the two outermost cutting portions of the cutting member along the thickness direction of the cutting member. The limiting portions serve to position and limit the conductive busbar, and also strengthen the structure of the cutting member, preventing bending or folding.

[0007] In some embodiments, the cutting portion has a first side and a second side disposed on opposite sides in the thickness direction. The first side extends parallel to the first direction, and the second side extends along the first direction and inclined toward the first side. The second side intersects with the first side and forms the second cutting blade at the intersection. The first side abuts against the limiting portion. This arrangement can better strengthen the cutting component.

[0008] In some embodiments, the included angle between the first side and the second side is α, where α < 15°, to reduce the cutting resistance experienced by the cutting portion.

[0009] In some embodiments, the positioning member includes two limiting portions spaced apart along the second direction and a holding portion located between the two limiting portions, wherein the holding portion and the two limiting portions form a U-shaped positioning groove; the limiting portion extends along the first direction to the side of the second cutting edge away from the holding portion, and as the cutting member approaches the conductive busbar, the limiting portion can first position the conductive busbar, thereby ensuring the accuracy of the cutting.

[0010] In some embodiments, the first cutting edge includes a first cutting segment and a second cutting segment. The shape of the first cutting segment matches half of the outer contour of the metal rod. The second cutting segment extends linearly from the free end of the first cutting segment along the first direction. The first cutting segment is used to cut the outer rubber layer of the metal rod, and the second cutting segment is used to ensure the cutting depth and ensure that the rubber layer is cut off. With this configuration, the first cutting edges of the two cutting pieces can adopt the same structure, which facilitates production.

[0011] In some embodiments, the metal rod has a circular cross-section, the first cutting segment is semi-circular, and the first cutting edge is crescent-shaped.

[0012] In some embodiments, the maximum thickness of the cutting portion is 1.2 mm to 1.8 mm, which is used to reduce the cutting resistance experienced by the cutting portion.

[0013] In some embodiments, the cutting angle of the first cutting edge is greater than that of the second cutting edge.

[0014] In some embodiments, the temperature of the cutting element after being heated by the heating element is 100°C to 120°C. At this temperature, the cutting element experiences less cutting resistance and will not burn the rubber, thereby ensuring high cutting quality.

[0015] Due to the application of the above technical solution, the multi-metal rod conductive strip rubber cutting device of the present invention has the following advantages compared with the cutting device of the prior art: 1. The cutting element is heated by a heating element, and then used to cut the rubber. The heated element reduces the resistance encountered during the cutting process, making the cutting easier. Simultaneously, by controlling the heating temperature, the rubber can be prevented from burning, thus improving the smoothness of the cut and enhancing the cutting quality.

[0016] 2. The cutting component is equipped with multiple cutting sections. The two outermost cutting sections can cut the rubber on the outside of the conductive bar, while the middle cutting section can cut the rubber between two adjacent metal rods. Simultaneously, by providing a groove with a first cutting edge between adjacent cutting sections, and with the first cutting edge connecting to a second cutting edge, the cutting component creates a continuous cutting edge between adjacent cutting sections. This results in one side of the cutting component having a continuous cutting edge connecting all cutting sections, thus enabling complete and continuous cutting of the rubber.

[0017] 3. The sum of the lengths of the corresponding cutting sections of the two cutting parts is greater than the thickness of the rubber sheet, which ensures that the rubber sheet is completely cut off. By setting the blade shape of the first cutting edge, the equipment only needs to drive the two cutting parts to cut the conductive busbar once to completely cut off the rubber sheet. The operation is simple and can improve the working efficiency of the equipment.

[0018] 4. The moving components are equipped with positioning elements, which can position and fix the conductive busbar to ensure the cutting accuracy of the cutting parts and thus the cutting quality. The cutting parts and positioning elements are fixedly set, and they can move synchronously during operation, which simplifies the equipment structure. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] A conductive busbar 100 includes multiple metal rods 101 arranged parallel to each other, and rubber 102 covering the outer periphery of all the metal rods 101. In addition to being distributed around the periphery of the conductive busbar 100, rubber 102 is also present between adjacent metal rods 101. During the rubber 102 cutting process, the rubber 102 between the metal rods 101 also needs to be cut. See also Figure 1 , Figure 2 As shown, in this embodiment, the conductive busbar 100 has two parallel metal rods 101. In other embodiments, the number of metal rods 101 may be greater than two.

[0023] See Figure 3 , Figure 4The diagram illustrates a multi-metal rod conductive busbar rubber cutting device. The cutting device includes two moving components 200 arranged opposite each other along a first direction and capable of moving towards each other. Each moving component 200 includes a cutting element 1 and a heating element 2. The cutting element 1 includes a cutting portion 11 that pierces the rubber along the first direction. Each cutting portion 11 includes multiple portions spaced apart along a second direction perpendicular to the first direction. Any two adjacent cutting portions 11 are connected, forming a groove 12 between them capable of accommodating a single metal rod 101. The number of grooves 12 on each cutting element 1 is the same as the number of metal rods 101. The multiple cutting portions 11 cut rubber 102 in different areas. Specifically, when the conductive busbar 100 is fixed to the cutting device, and the multiple metal rods 101 are arranged parallel to the second direction, the two outermost cutting portions 11 of the cutting element 1 can cut the rubber 102 on both sides, while the multiple cutting portions 11 between the two outermost cutting portions 11 can cut the rubber 102 between the metal rods 101. In this embodiment, see [reference needed]. Figure 9 As shown, each cutting component 1 has three cutting sections 11, and two grooves 12 are formed between the three cutting sections 11. The two grooves 12 are respectively used to accommodate the two metal rods 101 of the conductive busbar 100.

[0024] In this embodiment, the heating element 2 is used to heat the cutting piece 1. Heating the cutting piece 1 reduces the resistance of the cutting part 11 piercing the rubber 102 and improves the flatness of the cut, thereby improving both cutting efficiency and cutting quality. Preferably, the heating element 2 heats the cutting piece 1 to 100°C to 120°C. At this temperature, not only can the rubber be easily cut, but the flatness of the cut can also be well guaranteed.

[0025] In this embodiment, the moving component 200 further includes a positioning component 3. The cutting component 1 is fixedly disposed on one side of the positioning component 3, and a positioning groove 30 is formed on the positioning component 3. Each cutting component 1 has a cutting position. When the cutting component 1 is in the cutting position, the conductive bus 100 is inserted into the positioning groove 30, and the positioning component 3 presses against the conductive bus 100 along the first direction, thereby realizing the positioning and fixing of the conductive bus 100, so that the cutting component 1 can accurately cut the rubber 102.

[0026] In this embodiment, the sum of the lengths of the cutting portions 11 on the two cutting members 1 along the first direction is greater than the thickness d of the rubber 102, thus ensuring that the cutting member 1 can completely cut the rubber 102.

[0027] In this embodiment, a first cutting edge 13 is formed on the sidewall of the groove 12, and a second cutting edge 110 is provided at the free end of the cutting portion 11 along the first direction. Specifically, the second cutting edge 110 is provided at the end of the cutting portion 11 away from the groove 12 along the first direction. The first cutting edge 13 and the second cutting edge 110 are connected and formed between two adjacent cutting portions 11 and extend continuously. Specifically, see Figure 9 As shown, the blade of the first cutting edge 13 is connected to the blade of the second cutting edge 110 and forms a continuous cutting surface on one side of the cutting part 1, connecting all the cutting parts 11. This enables continuous cutting of the rubber 102 and the formation of continuous cuts after cutting.

[0028] In this embodiment, see Figure 10 As shown, the two cutting elements 1, each in a cutting position, have their first cutting edges 13 overlapping to form a circumferentially closed cutting body. The shape of the cutting body matches the outer contour of the metal rod 101. Combined with the continuous cutting surface and cutting section 11, the cutting device can completely cut the rubber 102 using the two cutting elements 1. Specifically, the cutting device only needs to drive the two moving components 200 to move along the first direction, causing the two cutting elements 1 to cut the rubber 102, thus severing it. Combined with the heating effect of the heating element 2, the cutting operation is simple and efficient, and can ensure high cutting quality.

[0029] Specifically, the thickness d of the aforementioned rubber sheet 102 is the distance between the outer surfaces of opposite sides of the rubber sheet 102 in the first direction after the conductive bus 100 is fixed to the cutting equipment. See also Figure 2 As shown, in this embodiment, the outer contour of the rubber sheet 102 is rectangular. When the conductive bar 100 is fixed on the cutting device, the two metal rods 101 are arranged parallel to the second direction. The thickness d of the rubber sheet 102 is the distance between the two parallel sides of the rectangular contour that are perpendicular to the direction of the metal rods 101.

[0030] In this embodiment, the moving component 200 is configured to move up and down, with the first direction being the up and down direction. The conductive bar 100 is horizontally fixed to the cutting device, and the metal rods 101 of the conductive bar 100 fixed to the cutting device are arranged in the horizontal direction. The cutting component 1 cuts the rubber 102 in the up and down direction.

[0031] In this embodiment, see Figure 8 , Figure 9 As shown, the cutting section 11 has a first side surface 111 and a second side surface 112 disposed on opposite sides in the thickness direction. The first side surface 111 extends parallel to a first direction, and the second side surface 112 extends along the first direction and obliquely toward the first side surface 111. The second side surface 112 intersects with the first side surface 111, and a second cutting edge 110 is formed at the intersection. See also Figure 9 As shown, the second cutting blade 110 is used to allow the cutting part 11 to penetrate into the rubber 102 and cut the rubber 102.

[0032] In this embodiment, the included angle between the first side 111 and the second side 112 is α, where α < 15°, that is, the cutting angle of the second cutting blade 110 is < 15°, in order to reduce the resistance encountered by the cutting part 11 when cutting.

[0033] In this embodiment, the maximum thickness of the cutting part 11 is 1.2 mm to 1.8 mm, which reduces the resistance encountered by the cutting part 11 when it pierces the rubber 102.

[0034] In this embodiment, the multiple cutting portions 11 are fixed to each other. Specifically, the cutting element 1 is integrally formed, which improves the overall strength of the cutting element 1. In other embodiments, each cutting portion 11 can also be independently provided and the above-mentioned continuous cutting surface can be formed by splicing or other methods to ensure the continuity and integrity of the cutting.

[0035] In summary, to reduce resistance during the cutting process, the cutting section 11 is thinner and has a smaller cutting angle. However, with this design, the cutting part 1 is at risk of bending or breaking as a whole during the cutting process, and individual cutting sections 11 may also bend or break. In this embodiment, see... Figure 7 , Figure 8 As shown, the positioning member 3 includes two limiting portions 31 spaced apart along the second direction, forming the aforementioned positioning groove 30 between the two limiting portions 31. The two limiting portions 31 abut against the two outermost cutting portions 11 along the thickness direction of the cutting member 1. The limiting portions 31 can position and limit the conductive busbar 100 along the second direction. Specifically, when the cutting member 1 is in the cutting position, the two limiting portions 31 are located on both sides of the conductive busbar 100 to restrict its movement. Simultaneously, the limiting portions 31 also strengthen the cutting member 1. By abutting against the cutting portions 11 on both sides, they prevent bending or folding of the cutting member 1 in the second direction, and also prevent the cutting portions 11 on both sides from bending.

[0036] In this embodiment, see Figure 5 , Figure 8 As shown, the first side 111 abuts against the limiting part 31, which better meets the directional requirements for providing resistance to bending force and can also better and more stably strengthen the cutting part 11.

[0037] In this embodiment, the positioning member 3 also includes a pressing part 32 located between the two limiting parts 31, see [link to documentation]. Figure 6 , Figure 8As shown, a U-shaped positioning groove 30 is formed between the holding part 32 and the two limiting parts 31. When the cutting part 1 is in the cutting position, the holding part 32 presses against the conductive busbar 100 along the first direction, thereby fixing it in place. See also Figure 7 As shown, the limiting part 31 extends along the first direction to the side of the second cutting blade 110 away from the holding part 32. When the moving member 200 moves along the first direction and the cutting part 1 approaches the conductive busbar 100, the limiting part 31 contacts the conductive busbar 100 before the cutting part 11 and positions the conductive busbar 100, restricting the movement of the conductive busbar 100, thereby ensuring that each cutting part 11 can accurately cut the rubber 102.

[0038] In this embodiment, see Figure 7 As shown, the two outermost cutting portions 11 have their portions away from the groove 12 along the second direction abutting against the limiting portion 31. This portion is used to increase the strength of the cutting part 1 and does not participate in the cutting of the rubber 102. The portion of this portion that is close to the groove 12 along the second direction is the portion that effectively participates in the cutting.

[0039] In this embodiment, the two moving components 200 are symmetrically arranged in the vertical direction, and the two cutting parts 1 are mirror-symmetrically arranged, which simplifies the production difficulty of the moving components 200 and the cutting parts 1. In this embodiment, the blade of the first cutting edge 13 includes a first cutting segment 131 and a second cutting segment 132. The shape of the first cutting segment 131 matches half of the outer contour of the metal rod 101, and the second cutting segment 132 extends linearly from the free end of the first cutting segment 131 along a first direction. The two first cutting segments 131 can be spliced ​​along the first direction to form a circumferentially closed cutting body, while the second cutting segment 132 is used to increase the cutting depth of the cutting part 11, ensuring that the two corresponding cutting parts 11 along the first direction can cut the rubber 102.

[0040] In some embodiments, the two cutting elements 1 are asymmetrically arranged. For example, the second cutting segments 132 of the two cutting elements 1 have different lengths, or the first cutting blade 13 of one cutting element 1 has only the first cutting segment 131, while the first cutting blade 13 of the other cutting element 1 has both the first cutting segment 131 and the second cutting segment 132. As another example, based on the above embodiments, the first cutting segment 131 of one cutting element 1 matches a portion, rather than half, of the outer contour of the metal rod 101, and the first cutting segment 131 of the other cutting element 1 matches the outer contour of the remaining portion of the metal rod 101. The first cutting segments 131 of the two cutting elements 1 can be joined along a first direction to form a shape consistent with the outer contour of the metal rod 101.

[0041] In this embodiment, the metal rod 101 has a circular cross-section, and the first cutting segment 131 is semi-circular. In this embodiment, the first cutting edge 13 is crescent-shaped. In some embodiments, the metal rod 101 has a rectangular cross-section, and the first cutting segment 131 has a shape that matches the outer contour of a portion of the metal rod 101. Two first cutting segments 131 can be joined to form a rectangle that matches the outer contour of the metal rod 101. In this embodiment, the cutting angle of the first cutting edge 13 is greater than the cutting angle of the second cutting edge 110.

[0042] In this embodiment, the heating element 2 includes a heat-conducting block 21 and a heating rod 22 for heating the heat-conducting block 21. The cutting component 1 is connected to the heat-conducting block 21, and the positioning component 3 is also connected to the heat-conducting block 21. The cutting component 1 is typically made of metal and can be heated through heat transfer after being directly connected to the heat-conducting block 21. The positioning component 3 is made of a high-temperature resistant material to prevent deformation under high temperatures, which would affect the positioning effect. In this embodiment, the cutting component 1 has a connecting portion 14, which is directly and fixedly connected to the heat-conducting block 21. The cutting portion 11 extends from one side of the connecting portion 14 along a first direction. See also... Figures 5 to 9 As shown, the heat-conducting block 21 has two mutually perpendicular sides, and the cutting part 1 and the positioning part 3 are fixed on the two sides respectively.

[0043] In some embodiments, the material of the positioning member 3 has a certain thermal conductivity, so that the temperature of the positioning member 3 can also rise to a certain extent under the heating action of the heat-conducting block 21, thereby heating and softening the rubber 102 in contact with it, which helps the cutting member 1 to cut, or helps to peel off the cut rubber 102 in the subsequent operation.

[0044] In some embodiments, the cutting device can simultaneously drive two cutting elements 1 to cut the rubber sheet 102 and complete the cutting operation in one go, thereby greatly improving cutting efficiency. In other embodiments, the cutting device can perform cutting in stages, that is, first drive one cutting element 1 to cut the rubber sheet 102, then drive that cutting element 1 to retract, and then drive the other cutting element 1 to cut the rubber sheet 102 and cut it off before completing the cutting operation. The device using synchronous cutting needs to have a clearance setting for the two cutting elements 1, such as adjusting the blade angle of the second cutting edge 110 of the two cutting elements 1 to form a clearance.

[0045] In some embodiments, the positioning element 3 is disposed on the same side of the cutting element 1 in the two moving components 200, in which case the cutting device needs to perform a step-by-step operation when cutting the rubber 102. In other embodiments, the positioning element 3 is disposed on different sides of the cutting element 1 in the two moving components 200, in which case the cutting device can be configured to synchronously drive the two cutting elements 1 to cut the rubber 102.

[0046] In this embodiment, see Figure 5 , Figure 6 As shown, the moving component 200 includes a lifting seat 41 capable of moving up and down. The heat-conducting block 21 is fixedly disposed with the lifting seat 41, thereby being able to move up and down under the drive of the lifting seat 41. Specifically, a heat insulation component 42 is provided between the heat-conducting block 21 and the lifting seat 41 to prevent heat from being transferred to the lifting seat 41.

[0047] In this embodiment, the lifting seat 41 is driven to move up and down by the elbow clamp 300. In other embodiments, the lifting seat 41 can be driven by a cylinder, motor or other mechanism, and the cutting operation can be fully automated by setting a control system.

[0048] In this embodiment, a limiting bolt 43 is provided on the movement path of the lifting seat 41. By rotating the limiting bolt 43, the length of the limiting bolt 43 can be adjusted, thereby adjusting the movement distance of the lifting seat 41. Specifically, when the lifting seat 41 contacts the limiting bolt 43, the lifting seat 41 stops moving, thereby causing the cutting part 1 to stop moving. At this time, the cutting part 1 is in the cutting position, so the cutting position can be adjusted by adjusting the limiting bolt 43, thereby controlling the cutting depth of the cutting part 11.

[0049] In some embodiments, there is a preset distance between the holding portion 32 and the second cutting blade 110, and between the holding portion 32 and the bottom of the groove 12, so as to control the cutting depth.

[0050] In this embodiment, the cutting device is provided with a fixing mechanism 5 for fixing the conductive busbar 100. The fixing mechanism 5 has a cutting space 50, which is located between two cutting pieces 1. Specifically, the cutting space 50 is located between the two cutting pieces 1 in the vertical direction. When the conductive busbar 100 is fixed on the fixing mechanism 5, the area to be cut of the rubber 102 is located within the cutting space 50, which drives the two cutting pieces 1 to move into the cutting space 50 and cut the rubber 102.

[0051] In this embodiment, see Figure 11 , Figure 12 As shown, the fixing mechanism 5 includes a first fixing frame 51 and a second fixing frame 52 spaced apart along a third direction. The third direction is perpendicular to both the first and second directions, and the aforementioned cutting space is formed between the first fixing frame 51 and the second fixing frame 52. When the conductive busbar 100 is fixed to the fixing mechanism 5, the conductive busbar 100 is mounted on the first fixing frame 51 and the second fixing frame 52, and the area to be cut is suspended between the first fixing frame 51 and the second fixing frame 52. The conductive busbar 100 is fixed to the first fixing frame 51 and the second fixing frame 52 respectively to improve the stability of the fixation, thereby ensuring the cutting quality.

[0052] In this embodiment, a first positioning member 511 and a second positioning member 512 are fixedly disposed on the first fixing frame 51, and the first fixing frame 51 is also provided with a first fixing member 513 that can move closer to the second positioning member 512. See Figure 12 As shown, the first positioning member 511 is inverted L-shaped, having a first positioning portion extending in the vertical direction and a second positioning portion extending from the upper part of the first positioning portion in a third direction. When the conductive bus 100 is fixed to the fixing mechanism 5, the end of the conductive bus 100 abuts against the first positioning portion of the first positioning member 511 in the third direction, thereby achieving positioning of the conductive bus 100 in the third direction. At the same time, the second positioning portion is located above the conductive bus 100, used to prevent the conductive bus 100 from moving upward. The second positioning member 512 and the first fixing member 513 cooperate to clamp and fix the conductive bus 100.

[0053] In this embodiment, the second fixing frame 52 includes a fixedly disposed third positioning member 521 and a second fixing member 522 that can move closer to the third positioning member 521. With the cooperation of the third positioning member 521 and the second fixing member 522, the conductive busbar 100 can be clamped and fixed. In this embodiment, the first fixing member 513 and the second fixing member 522 are driven by the elbow clamp 300, respectively. In other embodiments, the first fixing member 513 and the second fixing member 522 can be driven by mechanisms such as cylinders and motors, and controlled by a control system.

[0054] In summary, the multi-metal rod conductive busbar rubber cutting device of this embodiment heats the cutting piece 1 using the heating element 2 during the cutting operation. Then, by driving the lifting seat 41, the cutting piece 1 and the positioning member 3 move together towards the conductive busbar 100. During this process, the two limiting parts 31 of the positioning member 3 first contact the conductive busbar 100 and position it. Then, the cutting piece 1 pierces the rubber 102. Due to the heating treatment, the cutting piece 1 can cut the rubber 102 more easily and smoothly. When both the upper and lower cutting pieces 1 have cut the rubber 102, the cutting task is completed, and the rubber 102 is completely severed. The device has high cutting efficiency and high cutting quality.
