Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, and in particular to a high-efficiency cutting device for metal product processing. Background Technology

[0002] Metal processing refers to the production activities of processing metallic elements or materials with metallic properties mainly composed of metallic elements. It includes various process technologies, such as stamping, engraving, grinding, and milling, with the aim of manufacturing the required parts, production line components, or large-scale structures.

[0003] Cutting is a common and important machining process in metal product processing. Existing metal product cutting devices often have several problems when clamping and fixing metal products. For example, most clamping structures can only perform simple parallel clamping, making it difficult to achieve stable and close-fitting fixation for irregularly shaped metal products. Workpiece wobbling easily occurs during cutting, affecting machining accuracy and surface quality. Furthermore, traditional cutting devices have limitations in adjusting the workpiece angle, failing to meet the needs of multi-angle cutting and limiting the diversity and flexibility of machining, thus lacking practicality. Therefore, it is necessary to redesign a more efficient cutting device for metal product processing to address these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency cutting device for metal product processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency cutting device for processing metal products includes a processing table. An adjusting frame is fixedly mounted on the upper surface of the processing table via a fixing plate. An adjusting shaft is rotatably mounted inside the adjusting frame. A conical rotor motor connected to the adjusting shaft is fixedly mounted on the outer wall of the adjusting frame. A placement frame is fixedly connected to the outer wall of the adjusting shaft via an adjusting mechanism. A bidirectional screw is rotatably mounted inside the placement frame. A stepper motor connected to the bidirectional screw is fixedly mounted on the outer wall of the placement frame via a limiting mechanism. Two moving blocks are threadedly mounted on the outer wall of the bidirectional screw via a limiting mechanism. An assembly plate is fixedly mounted on the upper surface of each of the two moving blocks. An installation frame is fixedly mounted on the upper surface of each of the two assembly plates via a connecting plate. Two clamping plates are rotatably mounted inside each of the two installation frames via a connecting mechanism. Hydraulic cylinders are fixedly mounted on the outer walls of each of the two installation frames. Two first connecting frames are fixedly mounted on the telescopic ends of each of the two hydraulic cylinders via moving plates. A second connecting frame is rotatably connected inside each first connecting frame via a connecting mechanism. Each second connecting frame is fixedly mounted on the outer wall of a corresponding clamping plate.

[0007] Preferably, the adjustment mechanism includes an adjustment block fixedly installed on the outer wall of the adjustment shaft, and the upper end face of the adjustment block is fixedly connected to the bottom wall of the placement frame.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the placement frame, and the limiting rod slides through the two moving blocks.

[0009] Preferably, the connecting mechanism includes a connecting shaft fixedly installed inside the mounting frame, and the clamping plate is rotatably installed on the outer wall of the connecting shaft.

[0010] Preferably, the connecting mechanism includes a connecting plate rotatably installed inside the first connecting frame, and the end of the connecting plate is rotatably connected to the inside of the second connecting frame.

[0011] Preferably, each of the clamping plates has an anti-slip pad fixedly installed on its inner wall, and each of the anti-slip pads is made of vulcanized rubber.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as hydraulic cylinders, moving plates and connecting plates, the extension end of the hydraulic cylinder drives the moving plate to move. Through the transmission mechanism composed of the first connecting frame, the connecting plate and the second connecting frame, the clamping plate is driven to rotate around the connecting shaft and clamp the workpiece. This linkage structure enables the clamping plate to adaptively adjust the angle according to the irregular contour of the metal product to achieve close clamping.

[0014] 2. By setting up components such as an adjusting shaft, a conical rotor motor, and adjusting blocks, the conical rotor motor drives the adjusting shaft to rotate stably within the adjusting frame. Through the rigid connection of the adjusting blocks, the rotational motion is precisely transmitted to the placement frame. This structure can achieve high-precision adjustment of the placement frame and the workpiece within a certain angle range to meet the cutting requirements of different angles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A high-efficiency cutting device for metal product processing includes a processing table 1. An adjusting frame 3 is fixedly mounted on the upper surface of the processing table 1 via a fixing plate 2. An adjusting shaft 4 is rotatably mounted inside the adjusting frame 3. A conical rotor motor 5 connected to the adjusting shaft 4 is fixedly mounted on the outer wall of the adjusting frame 3. A placement frame 7 is fixedly connected to the outer wall of the adjusting shaft 4 via an adjusting mechanism. A bidirectional screw 8 is rotatably mounted inside the placement frame 7. A stepper motor 9 connected to the bidirectional screw 8 is fixedly mounted on the outer wall of the placement frame 7. Two moving blocks 11 are threadedly mounted on the outer wall of the bidirectional screw 8 via a limiting mechanism. Assembly plates 12 are fixedly installed on the upper surface of each of the two assembly plates 12. Mounting frames 14 are fixedly installed on the upper surface of each of the two assembly plates 12 through connecting plates 13. Two clamping plates 16 are rotatably installed inside each of the two mounting frames 14 through a connecting mechanism. Hydraulic cylinders 18 are fixedly installed on the outer walls of each of the two mounting frames 14. Two first connecting frames 20 are fixedly installed on the telescopic ends of each of the two hydraulic cylinders 18 through a moving plate 19. A second connecting frame 22 is rotatably connected inside each first connecting frame 20 through a connecting mechanism. Each second connecting frame 22 is fixedly installed on the outer wall of the corresponding clamping plate 16.

[0023] The adjustment mechanism includes an adjustment block 6 fixedly installed on the outer wall of the adjustment shaft 4, and the upper end face of the adjustment block 6 is fixedly connected to the outer bottom wall of the placement frame 7.

[0024] Furthermore, the adjusting block 6 is made of high-strength alloy steel and is fixed to the adjusting shaft 4 by a key connection. It can withstand a large torque and ensure that the placement frame 7 can be stably adjusted in angle during the rotation of the adjusting shaft 4 to meet the cutting needs of different angles.

[0025] The limiting mechanism includes a limiting rod 10 fixedly installed inside the placement frame 7, and the limiting rod 10 slides through the two moving blocks 11.

[0026] Furthermore, the surface of the limiting rod 10 is chrome-plated, which has good wear resistance and smoothness, and can reduce friction with the moving block 11. This allows the moving block 11 to slide stably along the limiting rod 10 when the bidirectional screw 8 rotates, thereby ensuring the stability and accuracy of the movement of the moving block 11 and preventing it from deviating or getting stuck during the movement.

[0027] The connecting mechanism includes a connecting shaft 15 fixedly installed inside the mounting frame 14, and a clamping plate 16 rotatably installed on the outer wall of the connecting shaft 15.

[0028] Furthermore, the two ends of the connecting shaft 15 are connected to the mounting frame 14 by bearings. This mounting method can effectively reduce the friction when the clamping plate 16 rotates, so that the clamping plate 16 can rotate flexibly around the connecting shaft 15 at a certain angle, thereby better adapting to the clamping needs of metal products of different shapes.

[0029] The connecting mechanism includes a connecting plate 21 rotatably installed inside the first connecting frame 20, and the end of the connecting plate 21 is rotatably connected to the inside of the second connecting frame 22.

[0030] Furthermore, the connecting plate 21 is made of lightweight, high-strength aluminum alloy, which reduces the overall weight and motion inertia while ensuring structural strength.

[0031] Each clamping plate 16 has an anti-slip pad 17 fixedly installed on its inner wall, and each anti-slip pad 17 is made of vulcanized rubber.

[0032] Furthermore, the surface of the anti-slip mat 17 made of vulcanized rubber is provided with interlaced tooth-like patterns, which can increase the friction with the surface of metal products.

[0033] When using this utility model, the workpiece can be placed on the upper surface of the placement frame 7, and then the stepper motor 9 is started. The stepper motor 9, with its high-precision pulse control characteristics, drives the bidirectional screw 8 to rotate precisely. The bidirectional screw 8 adopts a bidirectional thread design. When the stepper motor 9 rotates forward, the two moving blocks 11 move relative to each other along the axial direction of the bidirectional screw 8 under the guidance and constraint of the limiting rod 10. With the rigid connection structure of the assembly plate 12, the connecting plate 13 and the mounting frame 14, the two mounting frames 14 are driven to move closer synchronously, and the workpiece is initially limited between the two. During this process, the sliding cooperation between the moving block 11 and the limiting rod 10 effectively avoids the offset and shaking during the movement, and ensures the movement accuracy of the mounting frame 14.

[0034] Next, the hydraulic cylinder 18 is activated. Utilizing the high thrust characteristics of hydraulic transmission, the extension end of the hydraulic cylinder 18 drives the first connecting frame 20 to move smoothly via the moving plate 19. The first connecting frame 20, the connecting plate 21, and the second connecting frame 22 form a linkage transmission mechanism. Driven by the hydraulic cylinder 18, the clamping plate 16 is pushed to rotate flexibly around the connecting shaft 15. When the clamping plate 16 contacts the workpiece surface, its adaptive rotation characteristics come into play. Through the rotational freedom of the connecting shaft 15, the clamping plate 16 can automatically adjust its angle according to the irregular surface contour of the workpiece, ensuring that each clamping plate 16 is in close contact with the workpiece surface. At the same time, the anti-slip pad 17 made of vulcanized rubber has a densely packed micro-protrusion structure on its surface. Under the action of clamping force, it undergoes elastic deformation, filling the micro-depressions on the workpiece surface and greatly increasing the contact friction. Even when facing the vibration and cutting force generated by high-speed cutting, it can effectively prevent the workpiece from sliding and ensure processing stability.

[0035] If a specific angle cutting is required on the workpiece, the conical rotor motor 5 is started. The conical rotor motor 5 has a unique built-in conical braking structure, which can output stable torque at the moment of start-up, driving the adjusting shaft 4 to rotate smoothly in the adjusting frame 3. The rotation of the adjusting shaft 4 is rigidly connected through the adjusting block 6, and the rotational motion is transmitted to the placement frame 7. The placement frame 7 is made of high-strength aluminum alloy, which reduces weight while ensuring structural strength and can quickly respond to the rotation of the adjusting shaft 4, so as to achieve high-precision angle adjustment of the workpiece.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
