Description

Technical Field

[0001] The utility model belongs to the technical field of shearing machines, and in particular relates to a composite shearing machine. Background Art

[0002] As a crucial piece of processing equipment in modern industrial production, shearing machines play a key role in sheet metal processing. Shearing machines primarily shear sheet metal through the up-and-down motion of a blade, thereby cutting it into specific sizes and shapes. Shearing machines are used in numerous industrial production scenarios, such as machinery manufacturing, automotive manufacturing, and construction, to precisely cut various sheet materials to meet the production needs of different products.

[0003] Most traditional shearing machines lack an effective holding function when cutting sheet materials. This prevents the sheet materials from being adequately fixed during the cutting process, making it easy for one side to warp. This unstable state not only affects the cutting accuracy, but also causes a large number of burrs on the edges of the sheet materials. The appearance of burrs not only reduces the appearance quality of the sheet materials, but may also cause harm to operators during subsequent processing and use, while also increasing the cost and workload of subsequent processing. Sheets are usually stored and transported in rolls. When the sheet materials are unrolled, they often take on a curved shape. Existing shearing devices are unable to flatten the sheet materials before cutting, resulting in large errors in the cutting size.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related technology, the utility model proposes a composite shearing machine to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a composite shearing machine, comprising a base, a support frame is provided on the top of the base, a driving mechanism is provided on the top of the support frame, a tool is provided at one end of the driving mechanism, a pressing assembly is provided at the other end of the driving mechanism, a leveling assembly is provided on the base, a plurality of rotating rollers are installed on the top of the base and are rotatable from the leveling assembly to the pressing assembly, a shearing plate is provided on the top of the base and below the support frame, the top of the shearing plate and the tops of the plurality of rotating rollers are on the same horizontal line, and the plate is cut by the tool moving downward to cooperate with the shearing plate.

[0008] Furthermore, the driving mechanism includes a cylinder, the cylinder is fixedly mounted on the support frame, and an output shaft is fixedly mounted on the output end of the cylinder.

[0009] Furthermore, the output shaft passes through the support frame, and a connecting plate is fixedly installed on the other end of the output shaft. The connecting plate is slidably installed with the support frame, and the tool is fixedly installed on the connecting plate.

[0010] Furthermore, the pressing assembly includes two fixed blocks, which are symmetrically fixed on the connecting plate. A sliding rod is slidably installed inside the fixed block, and a pressing plate is fixedly installed on the other end of the sliding rod, and both sliding rods are fixedly installed on the pressing plate.

[0011] Furthermore, a spring is sleeved on the circumferential surface of the sliding rod, one end of the spring is fixedly mounted on the fixed block and the other end is fixedly mounted on the pressing plate, a pressing groove is provided at the bottom of the pressing plate, and both ends of the pressing groove are inclined.

[0012] Furthermore, the leveling assembly includes two flattening conveyor rollers, both of which are rotatably mounted on the base, and the tops of the two flattening conveyor rollers located below are on the same horizontal line as the tops of the multiple rotating rollers and the shearing plate.

[0013] Furthermore, one end of each of the two flattening conveyor rollers is fixedly mounted with a synchronous wheel, and power transmission is achieved between the two synchronous wheels through a synchronous belt drive. The other end of one of the two flattening conveyor rollers is fixedly mounted with a drive motor, and the drive motor is fixedly mounted on the base.

[0014] The utility model has the following beneficial effects:

[0015] 1. When the tool of the present invention first contacts the plate, it mainly overcomes surface tension and initial resistance, and the cutting force is relatively small. At this time, the pressing component is in contact with the plate, the elastic potential energy is small, and the pressing force is moderate, which plays a preliminary fixing role. As the tool cuts into the plate, the thickness and contact area increase, and resistance such as the plate strength and friction needs to be overcome. The cutting force increases, and the elastic potential energy of the pressing component increases rapidly after sensing it, and the pressing force is greatly improved to cope with deformation and displacement of the plate, ensuring stability during cutting.

[0016] 2. When the sheet needs to be cut, the utility model first unfolds the sheet stored and transported in a roll, passes through the flattening component and is placed on the rotating roller. Since the rotating roller is rotatable, the sheet can be easily moved on it from one end of the flattening component to the pressing component. The sheet is flattened when passing through the flattening component, eliminating the bending shape caused by the roll unfolding, avoiding cutting size errors, and preparing for precise cutting.

[0017] 3. In this utility model, the plate moves on the rotating roller to the shearing plate position, the driving mechanism is started, the tool is driven downward and the pressing assembly moves synchronously. When the tool moves downward to cut the plate, the pressing assembly presses the plate to prevent it from warping. The tool and the shearing plate cooperate to accurately cut the plate into a specific size and shape, meeting the production needs of industries such as machinery manufacturing, automobile manufacturing, and construction.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figures 1-6 As shown, the utility model is a composite shearing machine, comprising a base 1, a support frame 2 is provided on the top of the base 1, a driving mechanism 3 is provided on the top of the support frame 2, a tool 8 is provided at one end of the driving mechanism 3, a pressing assembly 4 is provided at the other end of the driving mechanism 3, a leveling assembly 5 is provided on the base 1, a plurality of rotating rollers 6 are installed on the top of the base 1 and rotate from the leveling assembly 5 to the pressing assembly 4, a shearing block 7 is provided on the top of the base 1 and below the support frame 2, the top of the shearing block 7 is on the same horizontal line as the tops of the plurality of rotating rollers 6, and the plate is cut by the tool 8 moving downward and cooperating with the shearing block 7.

[0031] When the sheet needs to be cut, the sheet stored and transported in a roll is first unrolled, passed through the leveling assembly 5, and placed on the rotating roller 6 placed on the top of the base 1. Since the rotating roller 6 is rotatably installed, the sheet can be moved relatively easily on the rotating roller 6 and pushed from one end of the leveling assembly 5 toward the pressing assembly 4. When the sheet passes through the leveling assembly 5, the leveling assembly 5 flattens the sheet to eliminate the bending shape caused by the sheet being unrolled in a roll. This can effectively avoid the problem of cutting size error caused by the bending of the sheet, and prepare for subsequent precise cutting.

[0032] The sheet continues to move on the rotating roller 6 until it reaches the shearing block 7. At this time, the driving mechanism 3 is started, driving the cutter 8 downward on the one hand, and the pressing assembly 4 at the other end of the driving mechanism 3 also moves synchronously. When the cutter 8 descends to cut the sheet, the cutter 8 pressing assembly 4 presses the sheet to ensure that the sheet is fully fixed during the cutting process and prevents one side of the sheet from warping. Subsequently, the cutter 8 accurately cuts the sheet into a specific size and shape to meet the production needs of different products in the machinery manufacturing, automobile manufacturing, construction and other industries.

[0033] More specifically, when the tool 8 first contacts the plate, it mainly overcomes the surface tension and initial resistance of the plate. As the tool 8 gradually cuts into the plate, the thickness of the plate to be cut gradually increases, and the contact area between the tool 8 and the plate also increases. At this time, the resistance that needs to be overcome comes not only from the strength of the plate itself, but also from the friction between the tool and the plate. In addition, as the tool 8 moves downward, the cutting point of the plate may be deformed to a certain extent, which will also increase the difficulty of cutting. A greater cutting force is required to complete the cutting task, and the greater the cutting force, the more obvious the deformation of the plate.

[0034] When the cutter 8 first contacts the sheet, it primarily overcomes the sheet's surface tension and initial resistance, requiring a relatively small cutting force. Simultaneously, the pressing assembly 4 contacts the sheet. Since the force exerted by the cutter 8 on the sheet is relatively small at this point, the elastic potential energy within the pressing assembly 4 is also relatively small, resulting in a moderate pressing force on the sheet. This primarily serves to initially secure the sheet, preventing unnecessary movement when the cutter 8 first contacts it. As the cutter 8 gradually penetrates the sheet, the thickness of the sheet to be cut increases, and the contact area between the cutter 8 and the sheet also increases. The resistance to be overcome comes not only from the sheet's own strength, but also from the friction between the cutter 8 and the sheet, leading to a continuously increasing cutting force. During this process, the pressing assembly 4 senses the increasing cutting force exerted by the cutter 8 on the sheet. As the downward movement of the cutter 8 further compresses the elastic elements within the pressing assembly 4, the elastic potential energy within the pressing assembly 4 rapidly increases, significantly increasing the pressing force on the sheet. This allows for better handling of deformation and displacement of the sheet when subjected to greater cutting forces, ensuring that the sheet remains stable throughout the cutting process.

[0035] In one embodiment, for the above-mentioned driving mechanism 3 , the driving mechanism 3 includes a cylinder 301 , the cylinder 301 is fixedly mounted on the support frame 2 , and an output shaft 302 is fixedly mounted on the output end of the cylinder 301 .

[0036] The output shaft 302 passes through the support frame 2 , and a connecting plate 303 is fixedly mounted on the other end of the output shaft 302 . The connecting plate 303 is slidably mounted on the support frame 2 , and the tool 8 is fixedly mounted on the connecting plate 303 .

[0037] The pressing assembly 4 includes two fixed blocks 401, which are symmetrically fixed on the connecting plate 303. A sliding rod 402 is slidably installed inside the fixed block 401, and a pressing plate 403 is fixedly installed on the other end of the sliding rod 402, and both sliding rods 402 are fixedly installed on the pressing plate 403.

[0038] A spring 405 is sleeved on the circumferential surface of the sliding rod 402, one end of the spring 405 is fixedly mounted on the fixed block 401 and the other end is fixedly mounted on the pressing plate 403, a pressing groove 404 is provided at the bottom of the pressing plate 403, and both ends of the pressing groove 404 are inclined.

[0039] When the cylinder 301 is working, its output end pushes the output shaft 302 to move, and the output shaft 302 passes through the support frame 2. Since the other end of the output shaft 302 is fixedly installed with a connecting plate 303, and the connecting plate 303 is slidably installed with the support frame 2, the movement of the output shaft 302 can drive the connecting plate 303 to slide up and down on the support frame 2, and the tool 8 is fixedly installed on the connecting plate 303. In this way, when the connecting plate 303 slides up and down, the tool 8 also moves up and down to achieve the cutting action of the plate. During the downward movement of the tool, when the tool 8 approaches the plate, the pressing plate 403 connected to the other end of the sliding rod 402 slidably installed on the fixed block 401 first contacts the plate. At this time, as the connecting plate 303 continues to move downward, the pressing plate 403 Under the reaction force of the plate, the sliding rod 402 slides upward in the fixed block 401, compressing the spring 405. The spring 405 stores elastic potential energy in this process. At the same time, the reaction force of the spring 405 acts on the plate through the pressing plate 403 to press the plate. The pressing groove 404 opened at the bottom of the pressing plate 403 is inclined at both ends. This design can return the plate with a slightly offset position to the pressing plate 403. When the tool 8 continues to descend to cut the plate, as the cutting force of the tool 8 on the plate increases, the connecting plate 303 continues to descend, further compressing the spring 405, so that the elastic potential energy of the spring 405 increases, thereby increasing the pressing force on the plate accordingly, ensuring that the plate is fully fixed during the cutting process.

[0040] In one embodiment, for the above-mentioned leveling component 5, the leveling component 5 includes two flattening conveyor rollers 501, and the two flattening conveyor rollers 501 are both rotatably installed on the base 1, and the tops of the two flattening conveyor rollers 501 located below are on the same horizontal line with the tops of the multiple rotating rollers 6 and the shearing plate 7.

[0041] One end of each of the two flattening conveying rollers 501 is fixedly mounted with a synchronous wheel 502, and power transmission is achieved between the two synchronous wheels 502 through a synchronous belt 503. The other end of one of the two flattening conveying rollers 501 is fixedly mounted with a drive motor 504, and the drive motor 504 is fixedly mounted on the base 1.

[0042] When the drive motor 504 is started, the drive motor 504 drives a flattening conveyor roller 501 fixedly connected to it to rotate. Since a synchronous wheel 502 is fixedly installed on one end of the flattening conveyor roller 501, and the synchronous wheels 502 of the two flattening conveyor rollers 501 are driven by a synchronous belt 503, the power can be transmitted to the other flattening conveyor roller 501, so that the two flattening conveyor rollers 501 rotate synchronously. During the rotation process, the two flattening conveyor rollers 501 exert a certain pressure on the plate and convey the plate forward. Since the tops of the two flattening conveyor rollers 501 located below are on the same horizontal line as the tops of the multiple rotating rollers 6 and the shear plate 7, the plate can move smoothly between the rotating rollers 6 of the flattening conveyor roller 501 and the shear plate 7. When the plate passes through the two flattening conveyor rollers 501, the pressure and rotation of the flattening conveyor rollers 501 cause the bent part of the plate to be gradually flattened, thereby achieving flattening of the plate, providing good conditions for the subsequent tool 8 to accurately cut the plate, and avoiding errors in cutting size caused by bending of the plate.
