Aluminum plate cutting equipment

Abstract

The utility model discloses aluminum plate cutting equipment which is characterized in that a plurality of grooves are designed in the blade part of a cutter in the aluminum plate cutting equipment, and the contact area between the grooves and an aluminum plate can be effectively reduced in the cutting process, so that the resistance in the cutting process is reduced. According to the pressure intensity principle in physics, when the stressed area is reduced, the pressure intensity is increased, which means that under the same pressure, the cutting edges at the edges of the grooves can cut off the aluminum plate more efficiently. When a traditional straight cutter is used for cutting, due to the fact that the contact area between the traditional straight cutter and an aluminum plate is large, large pressure is often generated, and the aluminum plate deforms. According to the scheme, due to the design of the grooves, pressure distribution during cutting is more uniform, local pressure is reduced, and therefore deformation of the aluminum plate caused by too large pressure is effectively avoided. Therefore, the cutting quality is guaranteed, and the qualified rate of products is improved.

Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate processing, and in particular to an aluminum plate cutting device. Background Art

[0002] Aluminum plate cutting equipment is a kind of mechanical equipment specially used for cutting aluminum plates. It is mainly used in the aluminum processing industry, especially for the precise cutting of aluminum veneer, aluminum-plastic plate and other materials.

[0003] But in the traditional aluminum plate cutting process, the cutting equipment mainly relies on straight cutters to operate. However, this traditional method has significant defects. Since the contact surface between the straight cutter and the aluminum plate is large, the instantaneous pressure generated during cutting is large, which often causes the aluminum plate to deform significantly near the cutting point. The deformation of the aluminum plate not only affects the aesthetics of the product, but more importantly, it reduces its mechanical properties and precision, which is unacceptable in high-precision industrial applications.

[0004] In order to alleviate this problem, the industry has tried many methods in the past, such as improving cutting process parameters and using higher strength aluminum materials, but these methods can only reduce deformation to a certain extent, but cannot fundamentally solve the problem. Therefore, the development of a new type of cutting tool that can fundamentally reduce the pressure on the aluminum plate during cutting and prevent deformation has become an urgent need in the industry. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses an aluminum plate cutting device.

[0006] In order to achieve the above purpose, an aluminum plate cutting device includes a conveyor, a cutting assembly and a positioning assembly, wherein the cutting assembly is arranged near the outlet end of the conveyor, and the aluminum plate to be cut is transported to the cutting assembly through the conveyor;

[0007] The positioning assembly is arranged at the inlet end of the cutting assembly and close to the side of the conveyor, and is used to position the aluminum plate entering the cutting assembly;

[0008] The cutting assembly comprises a cutter, and the cutter is driven by a linear drive mechanism to perform cutting motion in an up-and-down direction. The blade of the cutter has a plurality of grooves, and the edges of the grooves all form chip cutting edges.

[0009] Specifically, the positioning assembly includes guide bars arranged on both sides of the conveyor, and a plurality of guide columns are rotatably mounted on the guide bars along the length direction thereof, and the guide columns are tapered from bottom to top.

[0010] A plurality of positioning posts are further installed on the guide bar, and the positioning posts are arranged close to the inlet end of the cutting assembly. A half-circle limiting edge is provided on the positioning post. When the aluminum plate to be cut passes through, the limiting edge is located on the upper side of the aluminum plate to be cut, thereby limiting the height position of the aluminum plate to be cut.

[0011] At the same time, the lower surfaces of the two ends of the limiting edge are provided with guiding inclined surfaces, and the guiding inclined surfaces are arranged to extend obliquely from the outside to the inside.

[0012] In the above scheme, the conveyor has a conveyor belt for conveying aluminum plates, and a plurality of adsorption holes are evenly distributed on the conveyor belt. A plurality of retractable membranes are arranged in the adsorption holes. When the aluminum plate is covered on the conveyor belt, the retractable membrane can form a negative pressure by changing its position in the adsorption hole, thereby adsorbing the aluminum plate.

[0013] Specifically, a circle of flexible sealing rings is arranged on the conveyor belt in the circumferential direction corresponding to the adsorption holes, and the flexible sealing rings are used for contacting and cooperating with the aluminum plate.

[0014] A magnetic sheet is arranged inside the telescopic membrane, and a plurality of electromagnets for aligning and cooperating with the magnetic sheet are arranged on the conveyor along its conveying direction.

[0015] The telescopic diaphragm is circular in shape, and a plurality of flexible telescopic sleeves are arranged at the edge of the telescopic diaphragm and are sleeved together from the outside to the inside. The end surface edges of the flexible telescopic sleeves are connected end to end to form a telescopic structure, one side edge of the flexible telescopic sleeve located on the outermost side is connected to the inner wall surface of the adsorption hole, and one side edge of the telescopic diaphragm located on the innermost side is connected to the telescopic diaphragm.

[0016] The groove is in a triangular shape, and each side of the triangular groove is a chip cutting edge.

[0017] Compared with the prior art, the present invention has the following advantages: the blade of the cutter in the aluminum plate cutting equipment of the present application is designed with a plurality of grooves, which can effectively reduce the contact area with the aluminum plate during the cutting process, thereby reducing the resistance during cutting. According to the pressure principle in physics, when the force area decreases, the pressure increases, which means that under the same pressure, the chip cutting edge at the edge of the groove can cut the aluminum plate more efficiently. When cutting, the traditional straight cutter often generates a large pressure due to its large contact area with the aluminum plate, which causes the aluminum plate to deform. In the present solution, the design of the groove makes the pressure distribution during cutting more uniform, and the local pressure is reduced, thereby effectively avoiding the deformation of the aluminum plate caused by excessive pressure. This not only ensures the cutting quality, but also improves the qualified rate of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further explained below in conjunction with specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] Example 1: Figure 1-4 As shown, an aluminum plate cutting device includes a conveyor 100, a cutting assembly 200 and a positioning assembly 300, wherein the cutting assembly 200 is arranged near the outlet end of the conveyor 100, and the aluminum plate to be cut is transported to the cutting assembly 200 through the conveyor 100;

[0027] The positioning assembly 300 is disposed at the inlet end of the cutting assembly 200 and close to the side of the conveyor 100, and is used to position the aluminum plate entering the cutting assembly 200;

[0028] The cutting assembly 200 includes a cutter 201 , which is driven by a linear drive mechanism to perform cutting motion in an up-and-down direction. The blade of the cutter 201 has a plurality of grooves 202 , and the edges of the grooves 202 all form chip cutting edges.

[0029] In this embodiment, the conveyor 100 is designed as a belt conveyor, which can effectively and continuously convey the aluminum plate to be cut to the cutting assembly 200. The surface of the belt is made of wear-resistant and non-slip material to ensure that the aluminum plate is stable during the conveying process and will not deviate.

[0030] The cutting assembly 200 is responsible for cutting the aluminum plate to a desired size and can be made of a high-strength, high-hardness alloy material to ensure accuracy and durability of the cutting.

[0031] The cutter 201 is designed to move up and down and is driven by a linear drive mechanism (such as a hydraulic cylinder or an electric push rod) to achieve efficient cutting action. The linear drive mechanism has precise control capabilities to ensure that the depth and speed of each cutting are consistent.

[0032] The blade of the cutter 201 is designed with a plurality of grooves 202. These grooves 202 not only reduce the resistance during cutting, but also form natural chip cutting edges at the edges of the grooves, making cutting smoother and also facilitating the discharge of chips to prevent clogging.

[0033] In a possible implementation, the positioning assembly 300 includes a set of adjustable positioning plates, which can adjust the position of the aluminum plate as needed to ensure that it accurately enters the cutting area.

[0034] The positioning plate is made of wear-resistant material and its surface is specially treated to reduce friction with the aluminum plate and prevent scratches. The positioning assembly 300 is also equipped with sensors to detect the position and status of the aluminum plate to ensure that each cut is made in the best position.

[0035] During the cutting process, the grooved edges create stress concentration points that make it easier to cut through the material. At the same time, the grooves also help to evacuate the chips, preventing blockage and re-cutting.

[0036] The blade of the cutter 201 is designed with multiple grooves 202, which can effectively reduce the contact area with the aluminum plate during the cutting process, thereby reducing the resistance during cutting. According to the pressure principle in physics, when the force area decreases, the pressure increases, which means that under the same pressure, the chip cutting edge at the edge of the groove can cut the aluminum plate more efficiently. When cutting, traditional straight cutters often generate greater pressure due to their large contact area with the aluminum plate, causing the aluminum plate to deform. In this solution, the design of the groove 202 makes the pressure distribution during cutting more uniform, and the local pressure is reduced, thereby effectively avoiding the deformation of the aluminum plate caused by excessive pressure. This not only ensures the cutting quality, but also improves the qualified rate of the product.

[0037] In another possible implementation, the positioning assembly 300 includes guide bars 301 arranged on both sides of the conveyor 100 , and a plurality of guide posts 302 are rotatably mounted on the guide bars 301 along the length direction thereof, and the guide posts 302 are tapered from bottom to top.

[0038] A plurality of positioning posts 303 are further installed on the guide bar 301. The positioning posts 303 are arranged close to the inlet end of the cutting assembly 200. A half-circle limiting edge 304 is provided on the positioning posts 303. When the aluminum plate to be cut passes through, the limiting edge 304 is located on the upper side of the aluminum plate to be cut, thereby limiting the height position of the aluminum plate to be cut.

[0039] At the same time, the lower surfaces of both ends of the limiting edge 304 are provided with guiding inclined surfaces 341 , and the guiding inclined surfaces 341 are arranged to extend obliquely from the outside to the inside.

[0040] Specifically, the positioning assembly 300 includes two guide bars 301 , which are respectively installed on both sides of the conveyor 100 to form a clamping and guiding structure.

[0041] The guide bar 301 is provided with a plurality of mounting holes along its length, and a guide post 302 is rotatably mounted in each mounting hole. The guide posts 302 are special in that they are tapered from bottom to top, and when the aluminum plate passes through the conveyor 100, the tapered design enables the guide posts 302 to gradually guide the aluminum plate, ensuring that the aluminum plate enters the cutting assembly 200 smoothly and accurately.

[0042] In order to further enhance the accuracy of positioning, a plurality of positioning posts 303 are also installed on the guide bar 301. These positioning posts 303 are arranged near the inlet end of the cutting assembly 200 to ensure accurate positioning when the aluminum plate is about to enter the cutting area. Each positioning post 303 is provided with a half-circle limiting edge 304, which is located on the upper side of the aluminum plate when the aluminum plate passes through, thereby limiting the position of the aluminum plate in the vertical direction and preventing it from jumping up and down during the cutting process.

[0043] Only half of the limit edge 304 can gradually rotate to the upper side of the aluminum plate when the aluminum plate passes. Compared with the full-circle limit edge 304, the full-circle limit edge 304 will produce continuous friction when in contact with the aluminum plate, which may not only cause scratches on the aluminum plate, but also accelerate the wear of the limit edge. The half-circle limit edge 304 only contacts the aluminum plate when necessary, thereby reducing friction and wear and extending the service life.

[0044] In addition, the lower surfaces of both ends of the limiting edge 304 are also designed with guiding inclined surfaces 341. The guiding inclined surfaces 341 are arranged to extend from the outside to the inside, and they are inclined outward from both ends of the limiting edge 304 and gradually extend inward. This helps to guide the aluminum plate to enter the restricted range of the limiting edge 304 more smoothly, reduce the resistance and friction of the aluminum plate during the entry process, and thus improve the efficiency and accuracy of cutting.

[0045] Example 2: Figure 5-7As shown, in order to enable the conveyor 100 to transfer the aluminum plate to be cut to the cutting assembly 200 more smoothly and accurately and avoid slippage and displacement between the aluminum plate and the conveyor 100, the conveyor 100 has a conveyor belt 101 for conveying the aluminum plate, and a plurality of adsorption holes 102 are evenly distributed on the conveyor belt 101. A plurality of retractable membranes 103 are arranged in the adsorption holes 102. When the aluminum plate is covered on the conveyor belt 101, the retractable membrane 103 can form a negative pressure by changing its position in the adsorption hole 102, thereby adsorbing the aluminum plate.

[0046] In this embodiment, a telescopic membrane 103 is provided in each adsorption hole 102. The telescopic membrane 103 is made of elastic material and has good elasticity and sealing properties. When the aluminum plate is covered on the conveyor belt 101, the telescopic membrane 103 can form a negative pressure environment by changing its position in the adsorption hole 102.

[0047] When the aluminum plate contacts the conveyor belt 101 and covers the adsorption hole 102, the telescopic diaphragm 103 will be pressed by the aluminum plate and move downward. Since the telescopic diaphragm 103 and the adsorption hole 102 have good sealing performance, when the diaphragm moves downward, a relatively closed space will be formed in the hole. As the diaphragm moves further downward, the air pressure in this closed space will decrease, forming a negative pressure. This negative pressure environment can generate a strong suction force, which can tightly adsorb the aluminum plate on the conveyor belt 101.

[0048] In addition, in order to enhance the stability and adsorption effect of the aluminum plate during the conveying process, a circle of flexible sealing rings 104 is specially provided on the conveyor belt 101 corresponding to the circumference of each adsorption hole 102. The flexible sealing ring 104 is made of soft and wear-resistant materials, such as silicone or rubber, to ensure that a good sealing effect can be formed when in contact with the aluminum plate. When the aluminum plate is placed on the conveyor belt 101, the flexible sealing ring 104 is in close contact with the aluminum plate, effectively preventing air from penetrating from the gap between the aluminum plate and the conveyor belt, thereby ensuring that a stable negative pressure environment can be formed inside the adsorption hole 102.

[0049] A magnetic sheet 131 is disposed inside the telescopic membrane 103 , and a plurality of electromagnets 132 for aligning with the magnetic sheet 131 are disposed on the conveyor 100 along the conveying direction thereof.

[0050] The telescopic diaphragm 103 is circular in shape, and a plurality of flexible telescopic sleeves 133 are provided at the edge of the telescopic diaphragm 103, which are sleeved together from the outside to the inside. The end surface edges of the flexible telescopic sleeves 133 are connected end to end to form a telescopic structure, and one side edge of the outermost flexible telescopic sleeve 133 is connected to the inner wall surface of the adsorption hole 102, and one side edge of the innermost telescopic diaphragm 103 is connected to the telescopic diaphragm 103.

[0051] In this embodiment, in order to control the telescopic movement of the telescopic diaphragm 103, a magnetic sheet 131 is provided on the inner side of the telescopic diaphragm 103. At the same time, a plurality of electromagnets 132 are arranged on the conveyor 100 along its conveying direction, and the positions of these electromagnets 132 correspond to the magnetic sheets 131. When the electromagnets 132 are energized, a magnetic field is generated to attract the magnetic sheets 131, thereby driving the telescopic diaphragm 103 to perform a telescopic movement. By precisely controlling the power on and off of the electromagnets 132, precise control of the telescopic diaphragm 103 can be achieved, thereby ensuring the stability and reliability of negative pressure adsorption.

[0052] The telescopic diaphragm 103 is provided with a plurality of flexible telescopic sleeves 133 which are sleeved together from outside to inside at its edge. The flexible telescopic sleeves 133 are made of elastic material and have good elasticity and sealing properties. The end edges of them are connected end to end to form a telescopic structure. The edge of one side of the flexible telescopic sleeve 133 located on the outermost side is connected to the inner wall surface of the adsorption hole 102, while the flexible telescopic sleeve 133 located on the innermost side is connected to the telescopic diaphragm 103. This design enables the telescopic diaphragm 103 to perform a telescopic action smoothly when subjected to an external force, while ensuring the sealing inside the adsorption hole 102.

[0053] Example 3: Figure 2 As shown, the groove 202 is in a triangular shape, and each side of the triangular groove 202 is a chip cutting edge. By designing the groove 202 into a triangle and making each side have a cutting function, the side of the triangle is a beveled edge, so that the chip cutting edge can gradually cut into the aluminum plate during the cutting process. Compared with the traditional straight-edge chip cutting edge, the beveled-edge chip cutting edge can gradually deepen the cutting depth during cutting, reducing the impact on the tool and the material, thereby extending the service life of the tool and improving the stability and precision of cutting.

[0054] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
