Description

Technical Field

[0001] This utility model relates to the field of metal plate shearing technology, and in particular to a precision shearing device for non-ferrous metal smelting and rolling products. Background Technology

[0002] In the field of non-ferrous metal smelting and processing, rolled products (such as plates and strips) are important intermediate or final products. During the production process, these rolled products often require precise shearing according to the dimensional requirements of subsequent processing or direct application. The shearing quality, especially the straightness and perpendicularity of the cut, and the presence of defects such as burrs and tears, directly affects the product yield, aesthetics, and the processing quality and efficiency of subsequent welding, stamping, and other processes. Therefore, high demands are placed on precision shearing equipment used for non-ferrous metal rolled products.

[0003] Currently, existing shearing devices, such as some mechanical or hydraulic shearing machines, work on the principle of using a drive mechanism (such as a hydraulic cylinder) to move the upper blade holder and cutter downwards, creating a shearing action with the fixed lower die (support platform) to cut the sheet metal. However, in practical use, especially when performing high-precision shearing, these devices often reveal some shortcomings. These shortcomings are mainly reflected in the following aspects: Insufficient stability of the cutting motion: Under the uneven load generated by shearing forces, especially when shearing thick or hard metal sheets, traditional single-point or unidirectional guided cutter holders are prone to slight lateral twisting or vibration. This unstable motion causes the cutter to deviate from the intended vertical path during its descent.

[0004] The quality of the cut is difficult to guarantee: Due to the instability of the cutting blade movement mentioned above, the direct consequence is that the cut may not be perpendicular, may be oblique, or may have a rough cut surface with burrs or even local tears. This is unacceptable for precision machining applications that require clean cuts, often requiring additional grinding and trimming processes, increasing production costs and time. Therefore, a precision shearing device for non-ferrous metal smelting and rolling products is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a precision shearing device for non-ferrous metal smelting and rolling products, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides a precision shearing device for non-ferrous metal smelting and rolling products, including a frame, an inner frame, a platform, and a support. The inner frame is fixedly connected to the inner side of the frame, the platform is fixedly connected to the inner side of the frame, and the support is fixedly connected to the top of the platform. A cutter is movably connected to the inner side of the inner frame, and one side of the cutter is movably connected to the edge of the top surface of the support platform. The back of the cutter is fixedly connected to a back frame, and several connectors are fixedly connected to the horizontal part of the back frame. The end of the connector is movably connected to a guide wheel; An inner beam is fixedly connected to the inner side of the frame, and the guide wheel is movably connected to the side of the inner beam. An extension head is fixedly connected to the end of the cutter, a secondary connector is fixedly connected to the side of the extension head, a guide is fixedly connected to the inner side of the frame, and a guide wheel is movably connected to the end of the secondary connector. The guide wheel is movably connected to the surface of the guide. A hydraulic cylinder is fixedly connected to the top of the frame, and a guide rod is movably connected to the output end of the hydraulic cylinder. A slanted groove is opened at the end of the cutter, and the guide rod is movably connected in the slanted groove.

[0008] Preferably, in any of the above embodiments, the frame is welded to the inner frame, and the two sides of the platform are fixedly connected to the support plates, which are located below the two sides of the support platform.

[0009] The above technical solution involves placing a rolled metal sheet on a support platform. The hydraulic cylinder is activated, and its output pushes a guide rod downwards. Since the guide rod is movably connected to a groove at the end of the cutter, its downward movement causes the cutter to perform a shearing motion downwards via the groove.

[0010] During the downward shearing process, the bidirectional guide structure plays a crucial role. On the back of the cutter, a back frame is fixed to the cutter, and guide wheels are movably connected to the joint ends of the transverse section of the back frame. These guide wheels are movably connected to the side of the inner beam fixed to the inside of the frame, providing guidance for the back of the cutter. On the front of the cutter, guide wheels are also movably connected to the end of the auxiliary joint fixed to the side of the extension head. These guide wheels are movably connected to the surface of the guide component connected to the inside of the frame via right-angle brackets, providing guidance for the front of the cutter. The bidirectional guide structure effectively prevents the cutter from twisting and vibrating during shearing, ensuring that the cutter presses down vertically and precisely shears the rolled metal sheet placed on the support platform, resulting in a straight, burr-free cut.

[0011] Preferably, in any of the above solutions, the cutter is made of alloy steel, and the back frame is welded to the cutter.

[0012] Preferably, in any of the above solutions, the cross-sectional shape of the back frame is T-shaped, and the back frame is connected to the connector by screws.

[0013] The core design of the device is to enhance shearing stability: This device features a bidirectional guiding structure to enhance shearing stability. The back of the cutter has a back frame, connector, and guide wheel structure, while the front of the cutter has a secondary connector, guide component, and guide wheel structure. This bidirectional guiding structure effectively prevents the cutter from twisting and vibrating during shearing, ensuring that the cutter presses down vertically, making the shearing process more stable and improving shearing accuracy. The stable movement of the cutter ensured by the bidirectional guiding structure results in a straight, burr-free cut. This is particularly important for high-precision shearing or applications requiring high-quality cut surfaces, meeting the stringent requirements of subsequent processing for the cut quality of rolled metal sheets and reducing the difficulty and cost of subsequent processing.

[0014] Preferably, in any of the above embodiments, the connector is located on the back of the cutter, and the guide wheel is made of stainless steel.

[0015] Preferably, in any of the above solutions, the extension head is welded to the end of the cutter, the sub-connector is located on the front of the cutter, and the guide is connected to the frame via a right-angle bracket.

[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This precision shearing device for non-ferrous metal smelting and rolling products features a bidirectional guiding structure designed to enhance shearing stability. The back of the cutter has a back frame, connector, and guide wheels, while the front of the cutter has a secondary connector, guide components, and guide wheels. The bidirectional guiding structure plays a crucial role during the downward shearing process. On the back of the cutter, the back frame is fixed to the cutter, and guide wheels are movably connected to the connector end of the transverse section of the back frame. These guide wheels are movably connected to the side of the inner beam fixed to the inner side of the frame, providing guidance for the back of the cutter. On the front of the cutter, the secondary connector end fixed to the side of the extension head is also movably connected to guide wheels. These guide wheels are movably connected to the surface of the guide component connected to the inner side of the frame via right-angle brackets, providing guidance for the front of the cutter. This bidirectional guiding structure effectively prevents the cutter from twisting and vibrating during shearing, ensuring the cutter presses down vertically, making the shearing process more stable and improving shearing accuracy. The stable movement of the cutter ensured by the bidirectional guiding structure results in straight, burr-free cuts. This is especially important for applications requiring high-precision shearing or high-quality cut surfaces, as it can meet the stringent requirements of subsequent processing for the cut quality of rolled metal sheets, reducing the difficulty and cost of subsequent processing.

[0022] like Figure 1-4 As shown, the precision shearing device for non-ferrous metal smelting and rolling includes a frame 1, an inner frame 2, a platform 3, and a support 4. The inner frame 2 is fixedly connected to the inner side of the frame 1, the platform 3 is fixedly connected to the inner side of the frame 1, and the support 4 is fixedly connected to the top of the platform 3. The inner side of the inner frame 2 is movably connected to a cutter 5, and one side of the cutter 5 is movably connected to the edge of the top surface of the support 4. The back of the cutter 5 is fixedly connected to a back frame 6, and several connectors 7 are fixedly connected to the horizontal part of the back frame 6. A guide wheel 8 is movably connected to the end of connector 7; An inner beam 9 is fixedly connected to the inner side of the frame 1, and the guide wheel 8 is movably connected to the side of the inner beam 9. An extension head 10 is fixedly connected to the end of the cutter 5, a secondary connector 11 is fixedly connected to the side of the extension head 10, a guide 12 is fixedly connected to the inner side of the frame 1, and a guide wheel 8 is movably connected to the end of the secondary connector 11. This guide wheel 8 is movably connected to the surface of the guide 12. A hydraulic cylinder 13 is fixedly connected to the top of the frame 1. A guide rod 14 is movably connected to the output end of the hydraulic cylinder 13. A slanted groove 15 is opened at the end of the cutter 5, and the guide rod 14 is movably connected in the slanted groove 15.

[0023] Example 1: The frame 1 is welded to the inner frame 2. Platform 3 has fixed support plates on both sides, with the support plates located below the sides of the support platform 4. The cutter 5 is made of alloy steel, and the back frame 6 is welded to the cutter 5. The back frame 6 has a T-shaped cross-section and is connected to the connector 7 with screws. The connector 7 is located on the back of the cutter 5, and the guide wheel 8 is made of stainless steel. The extension head 10 is welded to the end of the cutter 5, the secondary connector 11 is located on the front of the cutter 5, and the guide 12 is connected to the frame 1 via right-angle brackets.

[0024] Example 2: Place the metal rolled sheet on the support 4. Start the hydraulic cylinder 13, and the output end of the hydraulic cylinder 13 pushes the guide rod 14 downward. Since the guide rod 14 is movably connected in the inclined groove 15 opened at the end of the cutter 5, as the guide rod 14 moves downward, it will drive the cutter 5 to perform a shearing motion downward through the inclined groove 15.

[0025] During the downward shearing process of the cutter 5, the bidirectional guide structure plays a crucial role. On the back of the cutter 5, the back frame 6 is fixed to the cutter 5. Guide wheels 8 are movably connected to the ends of the joints 7 on the transverse portion of the back frame 6. These guide wheels 8 are movably connected to the sides of the inner beam 9, which is fixedly connected to the inside of the frame 1, providing guidance for the back of the cutter 5. On the front of the cutter 5, the end of the auxiliary joint 11, which is fixedly connected to the side of the extension head 10, is also movably connected to guide wheels 8. These guide wheels 8 are movably connected to the surface of the guide member 12, which is connected to the inside of the frame 1 via right-angle brackets, providing guidance for the front of the cutter 5. The bidirectional guide structure effectively prevents the cutter 5 from twisting and vibrating during shearing, ensuring that the cutter 5 presses down vertically, precisely shearing the metal rolled plate placed on the support 4, resulting in a straight, burr-free cut.

[0026] The working principle of this utility model is as follows: In a certain location, a batch of non-ferrous metal rolled sheets needed to be sheared with high precision to meet the stringent requirements for the cut surface in subsequent processing. The precision shearing device for non-ferrous metal smelting rolled products described in this application was selected.

[0027] The operator first installs and debugs the device, ensuring that the frame 1 and inner frame 2 are firmly welded, the support plates on both sides of the platform 3 are correctly positioned and located below the sides of the support platform 4, the back frame 6 and cutter 5 are firmly welded, the back frame 6 and connector 7 are tightly connected by screws, the guide wheel 8 is made of stainless steel and rotates flexibly, the extension head 10 is reliably welded to the end of the cutter 5, the auxiliary connector 11 is accurately positioned, and the guide 12 is stably connected to the frame 1 by right-angle brackets.

[0028] Next, the operator places the metal rolled sheet to be sheared smoothly on the support platform 4 and adjusts its position. Then, the hydraulic cylinder 13 is activated, and the output end of the hydraulic cylinder 13 pushes the guide rod 14 downward. The guide rod 14 slides in the inclined groove 15 at the end of the cutter 5, driving the cutter 5 to perform a downward shearing motion. During the downward pressing of the cutter 5, the guide wheel 8 on the back rolls along the side of the inner beam 9, and the guide wheel 8 on the front rolls along the surface of the guide member 12, providing stable bidirectional guidance for the cutter 5. The cutter 5 successfully shears the metal rolled sheet, resulting in a straight cut without burrs, which fully meets the requirements of subsequent processing. The entire shearing process is efficient and stable, greatly improving production efficiency and product quality.

[0029] Compared with the prior art, the present invention has the following advantages: This precision shearing device for non-ferrous metal smelting and rolling products features a bidirectional guiding structure designed to enhance shearing stability. The back of the cutter 5 has a back frame 6, a connector 7, and guide wheels 8, while the front of the cutter 5 has a secondary connector 11, a guide component 12, and guide wheels 8. The bidirectional guiding structure plays a crucial role during the downward shearing process of the cutter 5. On the back of the cutter 5, the back frame 6 is fixed to the cutter 5, and the end of the connector 7 on the transverse part of the back frame 6 is movably connected to the guide wheels 8. These guide wheels 8 are movably connected to the side of the inner beam 9 fixed to the inner side of the frame 1, providing guidance for the back of the cutter 5. On the front of the cutter 5, the end of the secondary connector 11 fixed to the side of the extension head 10 is also movably connected to the guide wheels 8. These guide wheels 8 are movably connected to the surface of the guide component 12 connected to the inner side of the frame 1 via right-angle brackets, providing guidance for the front of the cutter 5. This bidirectional guiding structure effectively prevents the cutter 5 from twisting and vibrating during shearing, ensuring that the cutter 5 presses down vertically, making the shearing process more stable and improving the shearing accuracy. The bidirectional guiding structure ensures stable movement of the cutter 5, resulting in straight, burr-free cuts.
