Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a mechanical spinning equipment for metal processing. Background Art

[0002] In the field of metal processing, spinning is an important metal forming process, which is widely used in the manufacture of complex hollow workpieces, thin-walled containers, aerospace parts, automotive parts and other metal products with high precision and strength requirements. Traditional spinning equipment mainly applies pressure to the high-speed rotating workpiece through a spinning wheel, so that it gradually forms along the mold surface. This process usually requires the equipment to have high processing accuracy and stability, especially when processing complex curved surfaces, asymmetric workpieces and high-strength alloy materials, the spinning equipment needs to have good adaptability and sufficient pressure control capabilities.

[0003] The spinning equipment in the prior art often adopts a mechanical drive system, which usually includes a fixed spinning wheel and a driving mechanism, applying a fixed angle and pressure to complete the forming operation. However, this design has many shortcomings when facing complex shapes or asymmetric workpieces.

[0004] The motion path and pressure distribution of the spinning wheel are limited by the fixed mechanical structure, which may lead to overpressure or underpressure in certain areas of the workpiece, causing surface defects, uneven material thickness or stress concentration, and ultimately affecting the precision and quality of the product. This is especially true in the processing of high-strength materials or thin-walled workpieces. Due to the strong deformation resistance of the workpiece material, material cracking or excessive stretching is prone to occur during spinning. Summary of the invention

[0015] Working principle: When the device is needed, first fix the part to be processed on the outer wall of the forming block of the forming assembly. The forming block is fixed to the rotating rod through the connecting plate. The rotating rod is supported by the support seat 1 and the support seat 2 and the height is adjusted by the hydraulic rod 2 to ensure that the workpiece is in a suitable working position. The fixing assembly is moved by the electric slider on the slide rail. The connecting seat 1 and the connecting seat 2 drive the part position adjustment through the action of the hydraulic rod 1, so that the workpiece can be accurately positioned during the fixing process. The screw is connected to the motor 1, and the motor drives the connecting shaft to drive the rubber block to further clamp and fix the workpiece, ensuring that the workpiece will not deviate or loosen during the spinning process.

[0016] The linkage assembly drives the transmission wheel 1 and the connecting belt to drive the transmission wheel 2 to rotate. The transmission wheel 2 is connected to the driving screw, which transmits the rotational motion to the extrusion assembly through the support plate and the bottom plate. The extrusion assembly is linked by connecting rods 1 and 2, so that the rotating wheel 1 performs preliminary spinning forming on the workpiece under the guidance of the moving arm. The worm gear and worm inside the connecting rod 2 are linked, and the rotating shaft drives the rotating plate to rotate. By accurately adjusting the angle of the rotating wheel 1, it is ensured that the pressing wheel 1 can adapt to the complex shape of the workpiece surface, thereby effectively avoiding excessive compression or stretching of the material and ensuring the surface quality and forming accuracy of the workpiece.

[0017] The mechanical arm in the spinning assembly is fixed on the workbench, and the driving arm drives the second pressing wheel to perform secondary spinning on the workpiece. Through the cooperation of the internal ball structure and the spring, the second pressing wheel has a certain small range of motion during the spinning process, and can be dynamically adjusted according to the slight changes on the surface of the workpiece to avoid excessive local force on the workpiece, resulting in cracking or deformation. The spinning assembly further performs precision machining on the workpiece to ensure that the final formed workpiece has good surface quality and uniform thickness distribution.

[0018] The present invention provides a mechanical spinning device for metal processing, which has the following beneficial effects:

[0019] 1. The present invention achieves the effect of spinning the parts through the cooperation between the linkage component and the extrusion component when the fixed component is driven, and at the same time, the angle of the pressing wheel is adjusted through the internal adjustment component, thereby solving the problem that the pressing wheel cannot flexibly adapt to the shape changes of the workpiece when processing complex curved surfaces or asymmetric workpieces, resulting in uneven molding, surface defects and difficulty in controlling material thickness.

[0020] 2. The present invention achieves the function of adjusting the height of the fixing component and the forming component while fixing and forming the parts through the cooperation between the fixing component and the forming component, thereby solving the problem of unstable clamping of the workpiece and uneven clamping force during the forming process due to uneven height of the workpiece when processing special-shaped workpieces.

[0021] 3. The present invention achieves further spinning effect through the coordination between the internal structures of the spinning components. At the same time, through the coordination of the second pressing wheel, the ball and the spring, the second pressing wheel has a small range of motion when working, which solves the problem in traditional spinning equipment that the pressing wheel is too rigid, resulting in local overpressure of the workpiece during the spinning process, causing material cracking, surface dents and shape errors.

The pulley 2 506 is connected to the rotating rod 507 through a precision transmission mechanism. The outer wall of the rotating rod 507 is provided with a bearing 511.

The forming component 5 can flexibly adjust the position and support force according to the complexity and shape of the workpiece through the combined action of the pulley transmission system and the hydraulic support device. The power transmission of the motor 503 is accurate and stable. The combination of the pulley and the rotating rod 507 ensures that the equipment can work efficiently during the forming process, avoiding the phenomenon of uneven force on the workpiece due to the complex mechanical structure or unstable transmission of the traditional forming component 5. The precise coordination of the adjustable support structure and the bearing 511 greatly improves the stability of the equipment in the complex forming process and the quality of the workpiece, thereby improving the production efficiency and the qualified rate of the finished product.

[0038] Specifically, the lower surface of the robot arm 601 is fixed on the workbench 1 to ensure that the entire spinning assembly 6 has a stable support structure during processing. The driving end of the robot arm 601 is connected to the driving arm 602 through a linkage mechanism. The driving arm 602 is responsible for driving and controlling the motion of the pressure wheel 2 603 during the spinning process. The pressure wheel 2 603 is installed inside the driving arm 602 and serves as a key spinning element that is in direct contact with the workpiece. In order to ensure that the pressure wheel 2 603 can move flexibly and maintain a stable stress state during the spinning process, a plurality of ball bearings 604 are arranged inside the driving arm 602. These ball bearings 604 are located between the driving arm 602 and the pressure wheel 2 603. Through the rolling action of the ball bearings 604, the friction of the pressure wheel 2 603 during rotation is reduced, so that the pressure wheel 2 603 can adjust its angle and position more smoothly and flexibly with the movement of the driving arm 602, thereby applying appropriate pressure to the workpiece.
