Description

Technical Field

[0001] This utility model belongs to the field of metal cutting technology, and in particular relates to a metal cutting and shearing machine for the production of hardware parts. Background Technology

[0002] Metal cutting is essential in the production of hardware parts, playing a fundamental role and serving as a crucial step in ensuring the accuracy, efficiency, and quality of subsequent processing. Metal cutting is not only the starting point of hardware parts production but also the core link connecting material selection and finished product quality. By rationally selecting cutting processes (such as laser, waterjet, and plasma cutting), companies can ensure precision and efficiency while also considering cost control and complex design requirements, thereby comprehensively enhancing product competitiveness.

[0003] Metal cutting usually requires a shearing machine. There are many types of shearing machines on the market. For example, a shearing machine for anti-scratch plates for aluminum plate processing with publication number CN216990785U is disclosed on the China Patent Network. This shearing machine can be used for metal cutting in the production of hardware parts, but there are some defects and shortcomings that need to be improved: (1) Due to structural design reasons, the installation positions of the upper and lower blade holders of some existing shearing machines are often fixed, making it difficult to adjust the distance between the upper and lower blades, thus making it unsuitable for cutting metal plates of different thicknesses; (2) Most existing shearing machines adopt an integrated structure, and once the blade holder is installed, it is difficult to disassemble. When the blades are worn due to long-term use, it is not convenient to replace them, thus affecting the efficiency and effect of subsequent metal cutting; (3) After the metal cutting is completed, the workpiece of some existing shearing machines will fall onto the worktable and come into direct contact with the worktable, which can easily cause the surface of the workpiece to be damaged due to collision and friction with the worktable. Therefore, in view of the above problems, the metal cutting shearing machine for hardware parts production provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides a metal cutting and shearing machine for hardware parts production. The shearing mechanism utilizes a moving upper blade and a fixed lower blade to form a reasonable gap, applying shearing force to the metal sheet to achieve separation. The lower blade holder can drive a slider to move along a groove. As the lower blade holder moves, the position of the lower blade can be adjusted, allowing for adjustment of the distance between the lower and upper blades as needed, making the shearing machine suitable for cutting metal sheets of different thicknesses. The detachable design allows for easy replacement of the upper and lower blades when they wear down due to prolonged use. Various buffer strips cushion and protect the metal sheet after cutting and landing on the worktable, reducing the force exerted on the metal sheet by the worktable and effectively preventing damage to the surface of the metal sheet due to collision and friction with the worktable. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a metal cutting and shearing machine for producing hardware parts, comprising a worktable, a support cabinet fixedly connected to the bottom of the worktable, and a pair of brackets and a pair of guide rails fixedly connected to the top of the worktable. The brackets are symmetrically distributed on the front and rear sides of the worktable, and a support is provided directly above the brackets. The bottom end of the support is fixedly connected to both sides of the brackets, and a material pressing mechanism is provided on the support. The guide rails are located between the pair of brackets and symmetrically distributed on the left and right sides of the worktable.

[0009] Furthermore, the top surface of the bracket is level with the height of the lower blade, and the top surface of the bracket is provided with an anti-slip pad, the surface of which is provided with herringbone anti-slip texture.

[0010] Furthermore, a buffer pad is provided on the bottom surface of the pressure plate.

[0011] Furthermore, mounting rods are fixedly connected to the top of both ends of the upper tool holder. The rod body is provided with external threads and threaded with nuts that cooperate with it. Mounting holes are opened at both ends of the lifting plate. The diameter of the mounting holes is equal to the diameter of the mounting rods, and the center of each mounting hole corresponds one-to-one with the center of each mounting rod.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-7 As shown, this utility model discloses a metal cutting and shearing machine for producing hardware parts, comprising a worktable 1, a support cabinet 2 fixedly connected to the bottom of the worktable 1, and a pair of brackets 3 and a pair of guide rails 4 fixedly connected to the top of the worktable 1. The brackets 3 are symmetrically distributed on the front and rear sides of the worktable 1, and a support 5 is provided directly above the brackets 3. The bottom end of the support 5 is fixedly connected to both sides of the brackets 3, and a pressing mechanism is provided on the support 5. The brackets 3 are used to place the metal plates to be cut, and the guide rails 4 are located between the pair of brackets 3 and support the metal plates to be cut. The guide rails are distributed on the left and right sides of the workbench 1. The top of the guide rail 4 is provided with a sliding groove 6, and the outer side of the sliding groove 6 is provided with an adjustment groove 7. The top of the guide rail 4 is provided with a lower blade holder 8, and the top of the lower blade holder 8 is provided with a lower blade 9. The bottom sides of the lower blade holder 8 are fixedly connected with sliders 10. The outer side of the slider 10 is provided with a threaded groove 11, and the threaded groove 11 is threaded with a bolt 12 that mates with it. A fixing frame 13 is provided between the guide rails 4. The bottom of the fixing frame 13 is fixedly connected to the workbench 1, and a shearing mechanism is provided on its top.

[0033] The pressing mechanism includes an electric telescopic rod 14, which is installed on the top of the bracket 5. The bottom end of its output shaft is fixedly connected to a pressing plate 15. By driving the electric telescopic rod 14, the pressing plate 15 can be moved downward. When the pressing plate 15 contacts the metal plate placed on the bracket 3, the pressure applied by the pressing plate 15 can be used to press the metal plate tightly onto the bracket 3 to play a fixing role, thereby effectively preventing the metal plate from shifting during cutting and affecting the cutting accuracy.

[0034] The shearing mechanism includes a hydraulic cylinder 16, which is mounted on the top of the fixed frame 13. A lifting plate 17 is fixedly connected to the bottom of its output shaft. An upper blade holder 18 is mounted on the bottom of the lifting plate 17, and an upper blade 19 is mounted on the bottom of the upper blade holder 18. By driving the hydraulic cylinder 16, the lifting plate 17, together with the upper blade holder 18 and the upper blade 19, can be moved downward. At this time, a reasonable gap can be formed by the moving upper blade 19 and the fixed lower blade 9 to apply shearing force to the metal sheet, thereby achieving fracture separation.

[0035] The top surface of the bracket 3 is level with the height of the lower blade 9. When the metal sheet is placed on the bracket 3, the lower blade 9 can fit against the bottom of the metal sheet. The top surface of the bracket 3 is provided with an anti-slip pad 20. The surface of the anti-slip pad 20 is provided with herringbone anti-slip texture. The anti-slip pad 20 can be made of elastic materials such as rubber and is fixed by means of glue. The anti-slip texture on the surface of the anti-slip pad 20 can increase the friction between the metal sheet and the bracket 3 to play an anti-slip role, thereby preventing the metal sheet from slipping during cutting.

[0036] The bottom surface of the pressure plate 15 is provided with a buffer pad 21. The buffer pad 21 can be made of elastic materials such as sponge and fixed by means of glue. When the metal sheet is pressed onto the bracket 3 by the pressure plate 15, the buffer pad 21 can play a buffering and protective role to prevent the pressure applied by the pressure plate 15 from being too large and causing damage to the surface of the metal sheet.

[0037] The upper tool holder 18 has mounting rods 22 fixedly connected to the top of both ends. The rods 22 have external threads and are threaded with nuts 23. The lifting plate 17 has mounting holes 24 at both ends. The diameter of the mounting holes 24 is equal to the diameter of the mounting rods 22, and the center of each mounting hole 24 corresponds to the center of each mounting rod 22. Each mounting rod 22 can be aligned and passed through the corresponding mounting hole 24. The nuts 23 are then threaded onto each mounting rod 22 and tightened. The upper tool holder 18, together with the upper blade 19, can be fixedly installed at the bottom of the lifting plate 17 through the cooperation between the mounting rods 22, the mounting holes 24, and the nuts 23. When the upper blade 19 wears out due to long-term use, the upper tool holder 18 and the upper blade 19 can be removed from the lifting plate 17 by unscrewing the nuts 23 for replacement of the upper blade 19.

[0038] The thickness and height of the slider 10 correspond to the width and depth of the groove 6, respectively, and the center of each slider 10 corresponds to the center of each groove 6. When the lower blade holder 8 is installed on the top of the guide rail 4, each slider 10 can be inserted into and fit into the corresponding groove 6. The lower blade holder 8 can drive the slider 10 to move along the groove 6. When the lower blade holder 8 moves, the position of the lower blade 9 can be adjusted, so that the distance between the lower blade 9 and the upper blade 19 can be adjusted as needed, so that the shearing machine can be used to cut metal plates of different thicknesses.

[0039] The adjusting groove 7 is rectangular, and the threaded groove 11 is circular. The diameter of the threaded groove 11 is equal to the width of the adjusting groove 7, and the center of the threaded groove 11 and the adjusting groove 7 are on the same straight line. After the position of the lower tool holder 8 is adjusted, the bolt 12 can be passed through the adjusting groove 7 and screwed into the threaded groove 11. At this time, the position of the lower tool holder 8 can be fixed by the mutual cooperation between the bolt 12 and the threaded groove 11. When the lower blade 9 is worn due to long-term use, the lower tool holder 8 and the lower blade 9 can be removed from the guide rail 4 by unscrewing the bolt 12 so that the lower blade 9 can be replaced.

[0040] The top surface of the workbench 1 is provided with several buffer strips 25. The buffer strips 25 are located between a pair of guide rails 4. Their top surfaces are arc-shaped and the buffer strips 25 are distributed linearly at equal intervals along the length of the workbench 1. The buffer strips 25 can be made of elastic materials such as sponge and are fixed by means of glue. When the metal sheet is cut and falls onto the workbench 1, it will first come into contact with each buffer strip 25. At this time, the buffer strips 25 can fully absorb and decompose the impact force to reduce the force on the metal sheet from the workbench 1, thereby effectively preventing the surface of the metal sheet from being damaged by collision and friction with the workbench 1.

[0041] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0042] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all connected to the external main controller and mains power, and the main controller is a conventional known device that can play a control role.

[0043] The working principle of this utility model is as follows:

[0044] In use, the metal sheet to be cut is placed on two brackets 3 at both ends. Then, the electric telescopic rod 14 is driven to move the pressure plate 15 downward until it contacts the metal sheet on the bracket 3. At this point, the pressure applied by the pressure plate 15 firmly presses the metal sheet onto the bracket 3, thus fixing it in place. Next, the hydraulic cylinder 16 is driven to move the lifting plate 17, along with the upper blade holder 18 and the upper blade 19, downward together. At this point, the moving upper blade 19 and the fixed lower blade 9 form a reasonable gap to apply shearing force to the metal sheet, thereby achieving breakage and separation. After the metal sheet is cut and falls onto the worktable 1, it will first come into contact with the buffer strips 25. At this point, the buffer strips 25 can fully absorb and decompose the impact force, thereby reducing the force exerted on the metal sheet by the worktable 1. This effectively prevents damage to the surface of the metal sheet from collision and friction with the worktable 1. The lower blade holder 8 can drive the slider 10 to move along the slide groove 6. When the lower blade holder 8 moves, the position of the lower blade 9 can be adjusted, thereby adjusting the distance between the lower blade 9 and the upper blade 19 as needed, so that the shearing machine can be used to cut metal sheets of different thicknesses. The position of the lower blade holder 8 can be fixed by the cooperation between the bolt 12 and the threaded groove 11. When the lower blade 9 is worn due to long-term use, the lower blade holder 8 and the lower blade 9 can be removed from the guide rail 4 by unscrewing the bolt 12 for replacement. When the upper blade 19 is worn due to long-term use, the upper blade holder 18 and the upper blade 19 can be removed from the lifting plate 17 by unscrewing the nut 23 for replacement.
