Description

Technical Field

[0001] The invention belongs to the field of metal plate processing equipment, in particular to a metal material plate processing device. Background Art

[0002] In the processing of metal plates, cross-cutting, grinding and metal debris collection are key links. First, through the cross-cutting process, the metal plates are accurately cut to the required size to ensure that the processed plates meet the design requirements. Then, the grinding process processes the metal surface to remove burrs, rust or polish to improve the surface quality. Metal debris and particles will inevitably be generated during the grinding process. Therefore, in the process of metal plate processing, it is also necessary to pay attention to the collection of metal debris and particles.

[0003] A patent document with publication number CN220971396U discloses a cross-cutting processing device for titanium alloy plates, which includes a fixed plate, a first conveyor belt, a shell and an infrared sensor. The output end of the second telescopic device is fixedly connected to a pressure roller, and a flat roller is provided at the lower end of the pressure roller. A cylinder is fixedly connected to the center of the upper end surface of the support plate. The other end of the clamping plate and one end of the pressure roller are respectively provided with a distance sensor and a visual sensor. The output end of the fourth telescopic device is fixedly connected to a double-head grinder, and the output ends of the four first telescopic devices are all fixedly connected to brushes.

[0004] In the traditional metal plate processing technology, the cross-cutting process is a key link to ensure that the plate size meets the design requirements. During the cross-cutting process, the metal plate is sent to the intersection area of the cross-cutting tool and the cutting edge of the bottom plate below through a conveying device. At this time, the bottom end of the cross-cutting tool is higher than the cutting edge of the bottom plate, forming a certain height difference. When the tool and the cutting edge of the bottom plate are closely intertwined, the metal plate is cut and separated into two parts. At this time, the bottom end of the cross-cutting tool is lower than the cutting edge of the bottom plate. After cutting is completed, the metal plate is conveyed to a lower conveying structure, resulting in a height difference between the cutting surface of the metal plate before and after cutting. In the subsequent grinding process, since the structural design of the grinding equipment is usually based on the processing requirements of flat plates, it is difficult to adapt to the cutting surface of the metal plate with inconsistent height after cutting. This height difference makes it difficult for the grinding tool to perform comprehensive and high-precision grinding on the cutting surfaces of the two metal plates at the same time, resulting in low grinding efficiency and difficulty in ensuring processing accuracy, which in turn affects the overall processing quality and subsequent assembly performance of the metal plate.

[0005] To this end, the present invention provides a metal material plate processing device. Summary of the Invention

[0017] The beneficial effects of the present invention are as follows: 1.

At this time, the rotating shaft one is at the same height as the cutting surface of the metal plate above the lower pressure bottom plate, and the rotating shaft two is at the same height as the cutting surface of the metal plate on the conveyor rack in the box after cutting. Subsequently, the rotating shaft one and the rotating shaft two are driven by electric drive to rotate in the same direction, thereby driving the grinding belt to rotate at high speed.

A suction and chip collection structure is provided on the first connecting member and the second connecting member in the direction of the grinding belts. When the grinding belts rotate at high speed to grind the cut surface of the metal plate, the debris and metal particles generated by the grinding will spread in the surrounding environment. The suction and chip collection structure provided in this device is just facing the place where the debris and metal particles are generated, so these waste materials can be collected more quickly, thereby improving the surrounding environment.

[0019] 3. The metal plate processing device described in the present invention can discharge air in a circular shape through the annular guide member arranged on one side of the first connecting member. Its effect is similar to that of a bladeless fan, that is, it can guide the waste material on the outside of the grinding belt and blow the waste material toward the exhaust ring. The annular groove generates a suction force under the action of the external suction structure, which quickly collects the waste material into the inside of the annular groove and then sends it away through the suction pipe, thereby improving the surrounding environment. Since the annular air outlet of the annular guide member can directly act on the grinding position of the cutting surface of the metal plate, the collection efficiency is relatively high.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Figure 1-6 As shown, a metal material plate processing device according to an embodiment of the present invention includes a processing box 2 and an input machine 1 and an output machine 3 installed on both sides of the processing box 2. A lifting horizontal shear 5 is movably installed inside the processing box 2. A grinding and cleaning component 4 is also movably installed inside the processing box 2. The grinding and cleaning component 4 is located below the lifting horizontal shear 5. A feed port 21 is opened inside one side of the processing box 2. A pressing bottom plate 22 is fixedly installed at the bottom of the feed port 21. An inner-box conveying frame 24 is also fixedly installed inside the processing box 2. The inner-box conveying frame 24 and the pressing bottom plate 22 are respectively located on both sides of the lifting horizontal shear 5. The grinding and cleaning assembly 4 includes a fixed bar 41 fixedly installed inside the processing box 2 and a movable plate 42 slidably installed above the fixed bar 41. The grinding and cleaning assembly 4 also includes a first connecting member 6 and a second connecting member 7 fixedly installed at both ends above the movable plate 42. A rotating shaft 1 8 and a rotating shaft 2 9 are rotatably installed between the first connecting member 6 and the second connecting member 7. A grinding belt 43 is installed on the outer side of the rotating shaft 1 8 and the rotating shaft 2 9. The first connecting member 6 and the second connecting member 7 are provided with a chip suction and collection structure facing the grinding belt 43.

[0025] Specifically, the metal material plate is placed on the input machine 1. Under the conveying effect of the input machine 1, part of the metal material plate enters the inside of the feed port 21, and the part required for cutting is directly below the lifting horizontal shears 5. When cutting, the first connecting member 6, the second connecting member 7, the rotating shaft 1 8 and the rotating shaft 2 9 are on the outside of the processing box 2, and the metal material plate is fixed by pressing down a similar structure. At this time, the bottom end of the blade of the lifting horizontal shears 5 is higher than the cutting edge height of the pressing bottom plate 22, and the two are staggered. By driving the lifting horizontal shears 5 down until the bottom end of the blade of the lifting horizontal shears 5 is lower than the cutting edge height of the pressing bottom plate 22, the metal material plate in the staggered area is cut, and a part of it is still on the outside of the processing box 2 waiting for transportation and The next time you cut, the other part that has been cut out loses its support and falls above the conveyor frame 24 in the box. At this time, the horizontal height of the conveyor frame 24 in the box is lower than the horizontal height of the cutting edge of the pressing bottom plate 22. The lifting cross shears 5 are driven to rise and wait for the next cross cutting. In traditional technology, at this time, grinding is performed by a grinding structure that can contact the cutting surfaces of two metal plates. The most classic one is that two cutting surfaces of different heights contact different circumferential outer sides of the same metal wheel to achieve grinding. At this time, the contact angle and contact area of the circumferential outer side of the grinding wheel with the cutting surface are not ideal, and uniform and efficient grinding cannot be achieved. This contact method makes the grinding force unevenly distributed, which may cause insufficient or excessive grinding of the local cutting surface, thereby affecting The surface quality and flatness of the metal plate are affected. In addition, since the contact position between the grinding wheel and the cutting surface is inconsistent, in this device, after the lifting horizontal shears 5 rises, the first connecting member 6, the second connecting member 7, the rotating shaft 1 8, the rotating shaft 2 9 and the grinding belt 43 are driven by the movable plate 42 to move to the inside of the processing box 2 by electric drive. At this time, the rotating shaft 1 8 is consistent in height with the cutting surface of the metal plate above the lower pressing bottom plate 22, and the rotating shaft 2 9 is consistent in height with the cutting surface of the metal plate on the conveying rack 24 in the box after cutting. Then, the rotating shaft 1 8 and the rotating shaft 2 9 are driven by electric drive to rotate in the same direction, thereby driving the grinding belt 43 to rotate at high speed. By pushing a similar structure, the cutting surfaces of the two metal plates are close to the height at this time. The high-speed rotating grinding belt 43 can grind the metal plate cutting surfaces with different height differences at the same time, and the rotating shaft 1 8 is at the same height as the cutting surface of one metal plate, and the rotating shaft 2 9 is at the same height as the cutting surface of the other metal plate, that is, the grinding belt 43 is facing the two metal plate cutting surfaces when it is rotating at a high speed, so that the grinding effect can be achieved with full precision. In order to extend its working life, the traditional grinding structure usually expands its circumferential surface area and designs a grinding wheel with a larger diameter, which occupies more space. In this device, the grinding effect is achieved by connecting the grinding belt 43 with a larger surface area on the outer surface of the two rotating shafts 1 8 with smaller diameters and the rotating shaft 2 9, which can extend the working life of the grinding belt 43 and achieve a better grinding effect.A suction and chip collection structure is provided on the first and second connecting members 6 and 7 in the direction of the grinding belt 43. When the grinding belt 43 rotates at high speed to grind the cut surface of the metal plate, the debris and metal particles generated by the grinding will spread into the surrounding environment. The suction and chip collection structure provided in this device is precisely directed towards the place where the debris and metal particles are generated, which can collect these waste materials more quickly and improve the surrounding environment.

[0026] like Figure 2-4 As shown, a plurality of lifting and pressing members 23 are movably installed above the feed port 21. The lifting and pressing members 23 are used to press down and fix the metal material plate. A feed conveyor 26 is fixedly installed between the input machine 1 and the processing box 2. The grinding and cleaning assembly 4 is located between the feed conveyor 26 and the conveying frame 24 in the box.

[0027] A lifting conveyor frame 25 is installed on the inner top of the processing box 2. The lifting conveyor frame 25 is located directly above the inner conveyor frame 24 of the box. The horizontal height of the inner conveyor frame 24 is lower than the horizontal height of the feed conveyor 26.

[0028] Specifically, when the metal plate is on the input machine 1, it will be sent to the feed conveyor 26 for further transportation until the part of the metal plate to be cut is in the intersection area of the lifting horizontal scissors 5 and the cutting edge of the pressing bottom plate 22. At this time, multiple lifting and pressing parts 23 will be lowered to press down the metal plate to fix it, thereby facilitating the subsequent cutting by the lifting horizontal scissors 5.

[0029] like Figure 7-8 As shown, blocking wheels 81 are fixedly installed at both ends of the rotating shaft 8. The diameter of the two blocking wheels 81 is larger than the diameter of the rotating shaft 8. The rotating shaft 8 and the rotating shaft 2 9 are components made of the same structure. The second connecting member 7 and the movable plate 42 are detachably installed.

[0030] An annular guide 64 is fixedly mounted on the side of the first connecting member 6 facing the second connecting member 7 , and an exhaust ring 74 is fixedly mounted on the side of the second connecting member 7 facing the first connecting member 6 . An annular groove 741 is defined inside the exhaust ring 74 .

[0031] A suction pipe 75 is fixedly installed on one side of the second connecting member 7, and the suction pipe 75 is connected to the air extraction ring 74. An air duct 66 is fixedly installed on one side of the first connecting member 6. The lower part of the annular guide member 64 is connected to the cavity inside the movable plate 42, and the air duct 66 is connected to the cavity inside the movable plate 42. The suction pipe 75 is connected to the external suction equipment, and the air duct 66 is connected to the external air supply equipment.

[0032] The first and second connecting members 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75 The plate is fixed in the upper and lower positions, and the cooperation of the lifting conveyor frame 25 and the conveyor frame 24 in the box allows this group of metal plates to move close to the other side below the grinding belt 43 and make contact. That is, at this time, the outer side of the grinding belt 43 has simultaneously contacted the cut surfaces of the two metal plates, the contact distance is relatively close, and the contact area is large. Therefore, the grinding of the cut surfaces of the two metal plates will be more comprehensive and accurate. During the grinding, waste will be generated. The annular guide member 64 arranged on one side of the first connecting member 6 will discharge air in a circular manner, and its effect is similar to that of a bladeless fan, that is, it will guide the waste on the outside of the grinding belt 43 and blow the waste to the exhaust ring 74. The annular groove 741 generates a suction force under the action of the external suction structure, which quickly collects the waste into the inside of the annular groove 741 and then sends it away through the suction pipe 75 to improve the surrounding environment. Because the annular air outlet of the annular guide member 64 can directly act on the grinding position of the cut surface of the metal plate, the collection efficiency is relatively high.

[0033] like Figure 8 As shown, the first connecting member 6 includes a lower arc plate 62 fixedly mounted above the movable plate 42, one side of the lower arc plate 62 is connected to the air duct 66, the first connecting member 6 also includes an upper arc plate 61 movably mounted above the lower arc plate 62, a plurality of electric telescopic rods 63 are installed between the upper arc plate 61 and the lower arc plate 62, a drive motor 65 is fixedly mounted on one side of the upper arc plate 61, and the output end of the drive motor 65 is connected to the rotating shaft 8.

[0034] The second connecting member 7 includes a loading and unloading plate 71 installed at one end of the movable plate 42 and a lower arc plate 73 fixedly installed above the loading and unloading plate 71 . An upper arc plate 72 is installed above the lower arc plate 73 in a lifting manner.

[0035] The air pumping ring 74 is located on one side of the upper arc plate 72 . The lower part of the air pumping ring 74 is fixedly connected to the loading and unloading plate 71 . The loading and unloading plate 71 and the movable plate 42 are detachably installed.

[0036] Specifically, a lifting structure is also provided between the upper arc plate 2 72 and the lower arc plate 2 73, which has the same structure as the electric telescopic rod 63. When the electric telescopic rod 63 and the lifting structure drive the upper arc plate 1 61 and the upper arc plate 2 72 to rise, the distance between the rotating shaft 1 8 and the rotating shaft 2 9 increases to the limit value. At this time, the grinding belt 43 on the outside of the rotating shaft 1 8 and the rotating shaft 2 9 is tightened, and the rotating shaft 1 8 is rotated by the driving motor 65, and then the rotating shaft 2 9 is rotated through the linkage relationship of the grinding belt 43, that is, the grinding belt 43 starts to rotate at a high speed to achieve the grinding effect. When the grinding belt 43 needs to be replaced, the electric drive second connecting member 7, the rotating shaft 1 8, the rotating shaft 2 9, the first connecting member 6 and the movable plate 42 are moved to make the upper arc plate 2 72 appear on the outside of the processing box 2. By the detachable connection between the loading and unloading plate 71 and the movable plate 42, the second connecting member 7 is separated from the rotating shaft 1 8, the rotating shaft 2 9 and the movable plate 42, and the distance between the rotating shaft 1 8 and the rotating shaft 2 9 is reduced by contracting the electric telescopic rod 63. At this time, the grinding belt 43 on the outside of the rotating shaft 1 8 and the rotating shaft 2 9 is in a relaxed state. The grinding belt 43 at this time is replaced, and a new set of grinding belts 43 is sleeved on the outside of the rotating shaft 1 8 and the rotating shaft 2 9, which are still in a relaxed state. The distance between the rotating shaft 1 8 and the rotating shaft 2 9 is increased by extending the electric telescopic rod 63, so that the new set of grinding belts 43 on the outer side of the rotating shaft 1 8 and the rotating shaft 2 9 are tightened, and the loading and unloading plate 71 is reloaded, so that one end of the rotating shaft 1 8 and the rotating shaft 2 9 is inserted into the interior of the second connecting member 7, completing the replacement of the grinding belt 43 and extending the service life of the device.

[0037] Example 2: Figure 9-10 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: an air storage ring groove 641 is opened inside the annular guide 64, an annular resist bar 642 is fixedly installed on the inner side of the air storage ring groove 641, an arc ring 643 is also fixedly installed on the inner side of the air storage ring groove 641, and the arc ring 643 is positioned below the annular resist bar 642. The gap between the arc ring 643 and the annular resist bar 642 is the annular air outlet of the annular guide 64.

[0038] Specifically, the air duct 66 is connected to an external air supply device, and through gas pressurization, the gas will enter the interior of the annular guide 64 through the air duct 66 and the cavity below the annular guide 64 in the movable plate 42, that is, enter the interior of the air storage ring groove 641. The transverse diameter of the air storage ring groove 641 is larger than the longitudinal diameter, so most of the gas will first accumulate and pressurize inside the air storage ring groove 641. When the air inside the air storage ring groove 641 is full and released through the gap between the arc ring 643 and the annular support bar 642, through the Venturi effect, that is, when the gas passes through the narrow gap, the speed will increase and the pressure will decrease. At this time, the speed of the annular air flow will increase, thereby better taking away the waste generated at the grinding position, and thus efficiently completing the collection process.

[0039] Working principle: Place the metal material plate on the input machine 1. Under the conveying effect of the input machine 1, part of the metal material plate enters the inside of the feed port 21, and the part required for cutting is directly below the lifting horizontal scissors 5. When cutting, the first connecting member 6, the second connecting member 7, the rotating shaft 1 8 and the rotating shaft 2 9 are on the outside of the processing box 2. The metal material plate is fixed by pressing down a similar structure. At this time, the bottom end of the blade of the lifting horizontal scissors 5 is higher than the cutting edge height of the pressing bottom plate 22, and the two are staggered. By driving the lifting horizontal scissors 5 down until the bottom end of the blade of the lifting horizontal scissors 5 is lower than the cutting edge height of the pressing bottom plate 22, the metal material plate in the staggered area is cut, and a part of it is still on the outside of the processing box 2 waiting to be conveyed. The next cutting, the other part cut out loses support and falls above the conveyor frame 24 in the box. At this time, the horizontal height of the conveyor frame 24 in the box is lower than the horizontal height of the cutting edge of the pressing bottom plate 22. The lifting cross shears 5 are driven to rise to wait for the next cross cutting. In the traditional technology, at this time, grinding is performed by a grinding structure that can contact the cutting surfaces of the two metal material plates. The most classic one is that two cutting surfaces of different heights contact with different circumferential outer sides of the same metal wheel to achieve grinding. At this time, the contact angle and contact area of the circumferential outer side of the grinding wheel with the cutting surface are not ideal, and uniform and efficient grinding cannot be achieved. This contact method makes the grinding force unevenly distributed, which may cause insufficient or excessive grinding of the local cutting surface, thereby affecting The surface quality and flatness of the metal plate are affected. In addition, since the contact position between the grinding wheel and the cutting surface is inconsistent, in this device, after the lifting horizontal shears 5 rises, the first connecting member 6, the second connecting member 7, the rotating shaft 1 8, the rotating shaft 2 9 and the grinding belt 43 are driven by the movable plate 42 to move to the inside of the processing box 2 by electric drive. At this time, the rotating shaft 1 8 is consistent in height with the cutting surface of the metal plate above the lower pressing bottom plate 22, and the rotating shaft 2 9 is consistent in height with the cutting surface of the metal plate on the conveying rack 24 in the box after cutting. Then, the rotating shaft 1 8 and the rotating shaft 2 9 are driven by electric drive to rotate in the same direction, thereby driving the grinding belt 43 to rotate at high speed. By pushing a similar structure, the cutting surfaces of the two metal plates are close to the height at this time. The high-speed rotating grinding belt 43 can grind the metal plate cutting surfaces with different height differences at the same time, and the rotating shaft 1 8 is at the same height as the cutting surface of one metal plate, and the rotating shaft 2 9 is at the same height as the cutting surface of the other metal plate, that is, the grinding belt 43 is facing the two metal plate cutting surfaces when it is rotating at a high speed, so that the grinding effect can be achieved with full precision. In order to extend its working life, the traditional grinding structure usually expands its circumferential surface area and designs a grinding wheel with a larger diameter, which occupies more space. In this device, the grinding effect is achieved by connecting the grinding belt 43 with a larger surface area on the outer surface of the two rotating shafts 1 8 with smaller diameters and the rotating shaft 2 9, which can extend the working life of the grinding belt 43 and achieve a better grinding effect.A suction and chip collection structure is provided in the direction of the first connecting member 6 and the second connecting member 7 toward the grinding belt 43. When the grinding belt 43 rotates at high speed to grind the cut surface of the metal plate, the debris and metal particles generated by the grinding will diffuse into the surrounding environment. The suction and chip collection structure provided in the device is just oriented toward the place where the debris and metal particles are generated, so that these waste materials can be collected more quickly to improve the surrounding environment. The air duct 66 is connected to the air supply equipment externally. Through gas pressurization, the gas will enter the cavity below the annular guide 64 in the air duct 66 and the movable plate 42. The air enters the annular guide 64, that is, the air storage groove 641. The transverse diameter of the air storage groove 641 is larger than the longitudinal diameter, so most of the air will first accumulate and increase in pressure inside the air storage groove 641. When the air inside the air storage groove 641 is fully released through the gap between the arc ring 643 and the annular support strip 642, the Venturi effect, that is, when the air passes through the narrow gap, the speed increases and the pressure decreases. At this time, the speed of the annular air flow increases, thereby better carrying away the waste generated at the grinding position, and thus completing the collection process efficiently.
