Description

Technical Field

[0001] This invention relates to the field of disc shear technology, and more particularly to a metal baffle cutting device. Background Technology

[0002] Disc shears are important shearing devices widely used in industries such as metal processing, papermaking, and plastics. Their core feature is the use of one or more pairs of rotating disc-shaped blades as shearing tools. By adjusting the overlap and gap between the blades, they can longitudinally cut (slitting) or trim continuously moving sheet or strip materials.

[0003] Metal water barriers are protective and diversion components widely used in construction, industry, and transportation. Their manufacturing requires the use of disc shears for edge cutting of sheet metal. However, existing disc shears primarily rely on the continuous dripping of lubricating oil to lubricate and cool the cutter head. Since the overlap of the cutter head varies with the thickness of the sheet metal, thicker sheets result in a larger overlap area. This makes it difficult to achieve precise and rapid lubrication and cooling of the central area using existing methods like dripping or spraying lubricating oil. Increasing the oil volume to ensure lubrication wastes resources. Furthermore, insufficient cooling leads to severe heat buildup in the center, causing localized heat melting and adhesion of the sheet metal to the cutter head surface, forming built-up edges and affecting the edge cutting quality. Therefore, it is impossible to achieve precise lubrication and cooling of the cutter head area and the amount of oil used. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, disc shears cannot accurately perform rapid internal heat exchange and lubrication in the overlapping area during the cutting of sheet metal, which leads to increased material consumption and limited lubrication and heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal baffle cutting device, comprising two sets of disc cutters rotatably mounted on the side of the frame and rotating relative to each other, each disc cutter consisting of a drive shaft and a cutter head, characterized in that: it further comprises, The inner ring is used to connect the drive shaft and the cutter head. The surface of the inner ring has several flow grooves that pass through the left and right sides of the inner ring. The cutter head is fixed to the outside of the inner ring. Two sets of rotating disks are respectively arranged on the opposite sides of the two sets of inner rings, and the rotating disks are fixed on the drive shaft. A sealing ring is rotatably mounted on the surface of the drive shaft located at the lower part. An oil storage ring chamber is fixedly connected to the outer wall of the sealing ring. A telescopic control mechanism is fixedly installed inside the oil storage ring chamber. The flow groove is divided into several groups. A sealing component is movably sleeved on the side of each flow groove near the rotating disk. Telescopic grooves for sliding installation of the sealing component are also opened on the left and right sides of the flow groove on the side of the inner ring. The sealing component is slidably installed inside the telescopic groove.

[0006] In at least some embodiments, the flow channel is configured as an inclined structure, and each flow channel has a sealing valve for static sealing at both the left and right ends. There are two inner rings, and the flow channels inside the two inner rings are connected end to end. An oleophobic layer is integrally formed on the side of the outer layer of the flow channel.

[0007] In at least some embodiments, a bucket-shaped oil inlet groove is integrally formed at the outer end of the flow groove corresponding to one of the inner rings, and a bucket-shaped oil outlet groove is integrally formed at the outer end of the flow groove corresponding to another inner ring.

[0008] In at least some embodiments, the telescopic control mechanism includes a fixed tube, a telescopic rod is movably sleeved inside the fixed tube, one end of the telescopic rod is fixedly connected to a magnetic plate one, and the other end of the telescopic rod is fixedly connected to a magnetic plate two.

[0009] In at least some embodiments, the fixed tube is fixedly installed inside the oil storage ring chamber, and there are six fixed tubes. The six fixed tubes are divided into three groups. Two groups of fixed tubes are fixedly installed on the left and right sides of the flow channel in the through state, respectively. The other group of fixed tubes is fixedly installed on the outer side of the bottom end of the inner ring located near the bottom end. The magnetic plate and the magnetic block have the same magnetism.

[0010] In at least some embodiments, the sealing assembly includes two limiting rods that slide inside the telescopic groove. The outer bottom of the limiting rods is connected to a magnetic plate three. A vertical plate is fixedly installed in the middle of the magnetic plate three. Three sealing plugs are fixedly installed on the inner wall of the vertical plate. The outer wall of the magnetic plate three has the opposite magnetic properties to that of the magnetic plate one. The inner wall of the limiting rods and the inner side of the telescopic groove are magnetically attracted to each other.

[0011] In at least some embodiments, the length ratio of the three sealing plugs is set to 3:2:1 from high to low, and the inner shape of the three sealing plugs is adapted to the corresponding bucket-shaped oil inlet groove and bucket-shaped oil outlet groove.

[0012] In at least some embodiments, the circulating oil system includes an oil box for storing oil, with a connecting pipe 1 and a connecting pipe 2 fixedly connected to the surface of the oil box, an oil inlet hole on the surface of the oil storage ring, the oil inlet hole and the connecting pipe 1 being fixedly connected to each other, an oil pump being fixedly connected to one end of the connecting pipe 2, and a collection box being fixedly connected to one end of the oil pump.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0021] In the existing technology, due to the different overlap of the cutter heads, the overlap area will also change accordingly. The existing oil-based lubrication and cooling may result in a lot of waste and cannot effectively guarantee timely lubrication and cooling, leading to a decline in the edge quality of the sheet metal during long-term cutting.

[0022] The purpose of this invention is at least to achieve the effect of controlling the oil volume and rapid cooling by opening relevant independent oil passages inside the cutter head and using different overlapping areas to achieve different oil volume passage effects, thereby improving the overall stability of the cutting equipment during long-term operation.

[0023] Implementation examples, based on Figure 1 - Figure 9 ,like Figure 1 As shown, a metal baffle cutting device includes two sets of disc cutters rotatably mounted on the side of a frame 1 and rotating relative to each other. Each disc cutter consists of a drive shaft 4 and a cutter head 6. The device further includes... Inner ring 5, the inner ring 5 is used to connect drive shaft 4 and cutter head 6, the surface of the inner ring 5 is provided with a plurality of flow grooves 501 that pass through the left and right sides of the inner ring 5, and the cutter head 6 is fixed to the outside of the inner ring 5. Rotating disk 7, two sets of rotating disks 7 are respectively set on the side of the two sets of inner rings 5 ​​that are far apart, and the rotating disk 7 is fixed on the drive shaft 4; A sealing ring 401 is rotatably mounted on the surface of the drive shaft 4 located at the lower part. An oil storage ring 402 is fixedly connected to the outer wall of the sealing ring 401. A telescopic control mechanism 9 is fixedly installed inside the oil storage ring 402. The flow groove 501 is divided into several groups. A sealing component 10 is movably sleeved on the side of each flow groove 501 near the rotating disk 7. Telescopic grooves 502 for sliding installation of the sealing component 10 are also provided on the left and right sides of the flow groove 501 on the side of the inner ring 5. The sealing component 10 is slidably installed inside the telescopic groove 502.

[0024] like Figures 3 to 5 In this structure, the flow groove 501 is configured as an inclined structure. Each flow groove 501 has a sealing valve 503 for static sealing at both ends. There are two inner rings 5. The flow grooves 501 inside the two inner rings 5 ​​are connected end to end. An oil-repellent layer 504 is integrally formed on the side of the outer layer of the flow groove 501. A bucket-shaped oil inlet groove 5011 is integrally formed at the outer end of the flow groove 501 corresponding to one inner ring 5, and a bucket-shaped oil outlet groove 5012 is integrally formed at the outer end of the flow groove 501 corresponding to the other inner ring 5. The inclined structure of the flow channel 501 achieves two effects. First, when the flow channel 501 is open, it ensures that the oil flows under gravity, quickly completing the flow and accelerating the entry and exit of the oil. Second, when the flow channel 501 is closed, any oil that has not been discharged can flow back due to gravity as the inner ring 5 rotates to the top, widening its movement path and improving its heat absorption efficiency. The flow channel 501 on the surface of the inner ring 5 at the bottom also achieves accelerated downward discharge due to gravity when it reaches the bottom. Furthermore, the bucket-shaped oil inlet 5011 allows for a wide-mouth entry of oil into the flow channel 501, thus enhancing the effectiveness of the bucket-shaped oil inlet 5011. While releasing the seal, the speed at which the oil enters the flow channel 501 is accelerated. Similarly, the bucket-shaped oil outlet channel 5012 can also accelerate the outward discharge of the internal oil. It should be further explained that the effect of the oil flowing faster due to gravity created by the inclined flow channel 501, and the bucket-shaped structure of the port, can generate an instantaneous negative pressure when it is pulled out. The two work together to allow the aligned sealing valves 503 to expand and connect with each other, thereby achieving the effect of transporting the oil. In addition, with the oleophobic layer 504, when the oil leaks to the edge, it can be affected by the centrifugal force of rotation and re-enter the flow channel 504 port at other positions, which is convenient for subsequent recycling and achieves the effect of preventing waste.

[0025] like Figure 6 In the process, the telescopic control mechanism 9 includes a fixed tube 901, and a telescopic rod 902 is movably sleeved inside the fixed tube 901. One end of the telescopic rod 902 is fixedly connected to a magnetic plate 903, and the other end of the telescopic rod 902 is fixedly connected to a magnetic plate 904. The fixed tube 901 is fixedly installed inside the oil storage ring 402. There are six fixed tubes 901, which are divided into three groups. Two groups of fixed tubes 901 are fixedly installed on the left and right sides of the flow channel 501 in the through state, respectively. The other group of fixed tubes 901 is fixedly installed on the outer side of the bottom end of the inner ring 5 located near the bottom end. The magnetic plate 904 and the magnetic block 701 have the same magnetism. By using magnetic plates 904 and 701, which share the same magnetic properties, magnetic plates 904 and 701 are pushed out when they are on the same horizontal line. This causes magnetic plates 903 to move into the fixed tube 901, thereby controlling the corresponding actions of magnetic plates 903 and the sealing assembly 10. The polar axis distribution of multiple magnetic blocks 701 can effectively control the periodic movement of magnetic plates 904. Furthermore, the matching of the number of magnetic blocks 701 with the number of flow channels 501 can achieve more precise control. like Figure 7 In the process, the sealing assembly 10 includes two limiting rods 103 that slide inside the telescopic groove 502. The outer bottom of the limiting rods 103 is connected to a magnetic plate 104. A vertical plate 101 is fixedly installed in the middle of the magnetic plate 104. Three sealing plugs 102 are fixedly installed on the inner wall of the vertical plate 101. The outer wall of the magnetic plate 104 and the magnetic plate 903 have opposite magnetic properties. The inner wall of the limiting rods 103 and the inner side of the telescopic groove 502 are magnetically attracted to each other. The length ratio of the three sealing plugs 102 is set to 3:2:1 from high to low. The inner shape of the three sealing plugs 102 is adapted to the corresponding bucket-shaped oil inlet groove 5011 and bucket-shaped oil outlet groove 5012. The limiting rod 103 can not only limit the movement of the entire sealing assembly 10, but also attract the entire vertical plate 101 without external force, allowing it to adhere to the side of the flow channel 501, thus sealing the flow channel 501 with the sealing plug 102. The magnetic plate 104, under external force, can be moved outward by the magnetic attraction of the magnetic plate 903. By controlling its magnetic force to be greater than that of the limiting rod 103 and the internal magnetic force of the telescopic groove 502, the sealing plug 102 can be released. Furthermore, the sealing assembly 10 mainly moves outside the flow channel 501 via the limiting rod 103 and the telescopic groove 502. Therefore, the shape of the sealing plug 102 and the corresponding bucket-shaped oil inlet groove 5011 and bucket-shaped oil outlet groove 5012 are adapted to achieve a sealing effect. By setting its length to three lengths, different passage effects are achieved for the two inner rings 5 ​​under different overlapping surfaces, such as... Figure 3 , Figure 4 and Figure 5 The three different through-states correspond to the cutting of plates with progressively decreasing thickness. When the overlap is higher, more oil is required, and the heat dissipation efficiency is also higher. It should also be noted that the rotation speed of the inner ring 5 will change accordingly with the different plate thicknesses. The inner ring 5 rotates slower for thicker plates than for thinner plates, which ensures the corresponding cutting quality. Therefore, when the rotation speed of the inner ring 5 is different, the time it takes for the magnetic block 701 to pass through the magnetic plate 904 will be longer, and the movement distance of the sealing component 10 generated by magnetism will also be longer, which fully cooperates with the three lengths of the sealing plug 102 to achieve the effect of full opening. When the plate is thinner, the rotation speed of the inner ring 5 will be faster, and the time it takes for the magnetic block 701 to pass through the magnetic plate 904 will be shorter, thus making its movement distance shorter, thereby ensuring that the outer end of the non-through flow groove 501 remains in a sealed state, preventing internal oil leakage. like Figure 8 and Figure 9In the process, the circulating oil system 2 includes an oil box 201 for storing oil. The surface of the oil box 201 is fixedly connected to a first connecting pipe 202 and a second connecting pipe 203. The surface of the oil storage ring 402 is provided with an oil inlet 403. The oil inlet 403 and the first connecting pipe 202 are fixedly connected to each other. One end of the second connecting pipe 203 is fixedly connected to an oil pump 204. One end of the oil pump 204 is fixedly connected to a collection box 205. The side of the collection box 205 is provided with three oil suction grooves 206. The size of the three oil suction grooves 206 is adapted to the size of the flow channel 501. A collection plate 207 is detachably installed on the side of the collection box 205. An inclined platform 208 is integrally formed inside the collection plate 207. A filter screen 209 is fixedly installed at the bottom center of the inclined platform 208. The inclined structure of the ramp 208 allows the oil to actively sink when it enters the collection box 205, and then be filtered by the filter screen 209. This separates small debris inside the oil, ensuring the lubrication and cooling efficiency of the oil. Furthermore, the sides of the collection box 205 and the inner ring 5 are in close contact with each other, ensuring that when the oil enters the collection box 205, a small amount of leaked oil can be evenly coated on the side of the cutter head 6 to complete the corresponding lubrication operation.

[0026] In this embodiment, the overlap between the two cutter discs 6 is adjusted according to the actual thickness of the sheet material. Then, the existing drive structure is activated to drive the drive shaft 4 to rotate, so that the cutter discs 6 perform edge cutting on the sheet material. During the process, the flow grooves 501 inside the two inner rings 5 ​​correspond to each other. The bottom flow groove 501 of the higher inner ring 5 and the top flow groove 501 of the lower inner ring 5 are connected to each other. When they are aligned, the magnetic block 701 will control the magnetic plate 2 904 to be squeezed inward, and the magnetic plate 1 903 will retract to the innermost part of the fixed tube 901. Then, the magnetic force will be generated to attract the magnetic plate 3 104, so that the sealing plug 102 leaves the side of the flow groove 501. The oil enters the sealing ring 401 and the connecting pipe 1 202 through the oil inlet 403. The inner ring 5 forms a cavity for storage, which accumulates at the bottom due to gravity. When the sealing plug 102 leaves the flow channel 501, it directly enters the interior of the bucket-shaped oil inlet channel 5011, then breaks through the sealing valve 503 and enters the interior of the flow channel 501. During the flow, it absorbs heat and finally flows out from the bucket-shaped oil outlet channel 5012, entering the cavity formed by another oil storage ring 402 and the inner ring 5. The oil that is not discharged in time in the flow channel 501 continues to absorb heat. When the inner ring 5 flips to the bottom, it enters the collection box 205 through the negative pressure formed by the oil suction channel 206 to complete the collection. It is filtered by the filter screen 209 and finally introduced into the oil box 201 by the oil pump 204 to complete the recycling.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
