Description

Technical Field

[0001] The invention relates to the technical field of flange forging tables, in particular to a self-clamping and transpositioning machine tool spindle flange forging table and a transposition method thereof. Background Art

[0002] With the development of industrial automation, flange forging equipment is increasingly used in the field of mechanical processing. As an important connecting component of shaft parts, the forging accuracy and efficiency of flanges directly affect the performance of the equipment. However, existing flange forging machines still have significant technical bottlenecks in terms of clamping stability, position change flexibility, and multi-size adaptability. Specifically, the following problems are manifested: Traditional forging tables mostly use fixed clamping grooves or one-way clamping structures. The workpiece is prone to shaking or offsetting due to impact during the forging process, resulting in reduced forging accuracy. For example, some existing forging equipment uses a turntable to switch the discharge trough, but is not designed with a dynamic locking mechanism. The workpiece is easily deviated from the machining center under hydraulic impact, resulting in "offset" phenomenon. In addition, existing equipment mostly relies on manual or single rotation mechanism to adjust the workpiece position, which makes it difficult to achieve multi-faceted synchronous processing of complex forgings. For example, the multi-angle clamping device for forging stainless steel flanges for nuclear power use proposed in patent CN218362267U can adjust the flange position by rotating the table column, but it relies on manual operation, is inefficient, and cannot be linked to the forging action in real time. At the same time, the clamping structure of most existing forging tables is designed for a single size, making it difficult to adapt to flanges of different diameters. For example, the discharge trough mentioned in the forging table of a flange forging equipment proposed in patent CN202322185903 is of a unified size and cannot be compatible with workpieces of multiple specifications. Frequent replacement of fixtures is required, which significantly affects production efficiency.

[0003] To this end, we provide a self-clamping and transpositioning machine tool spindle flange forging table and a transposition method thereof to solve the above-mentioned problems. Summary of the Invention

[0014] A self-clamping and transpositioning method for a machine tool spindle flange forging table comprises the following steps: S1: First, place the spindle flange on the forging table at the top of the tank body, start the second motor to drive the second spindle to rotate, which in turn drives the first turntable to rotate. The rotation of the first turntable drives multiple arc-shaped clamping plates to synchronously gather and clamp the tank body; S2, starting the first motor to drive the first main shaft to rotate. The rotation of the first main shaft drives the connecting rod on the first secondary shaft to rotate. The rotation of the connecting rod drives the first swing arm to swing and drives the support frame at the bottom of the connecting rod to move vertically up and down, thereby driving the forging hammer at the bottom of the support frame to move vertically up and down.

When the third turntable rotates counterclockwise, since the clamping plate is embedded in the clamping groove, it can overcome the elastic squeezing of the wedge plate on the first outer gear ring and drive the first outer gear ring to rotate counterclockwise. When the third turntable rotates clockwise, the first outer gear ring is elastically squeezed by the wedge plate, and the clamping plate will squeeze the elastic paddle to cause it to deflect, and the first outer gear ring remains stationary, so that the first outer gear ring rotates intermittently and drives the groove body to rotate intermittently, thereby causing the main shaft flange clamped on the groove body to automatically shift position during forging.

[0015] Compared with the prior art, the present invention has the following beneficial effects: A trough body is rotatably provided on the machine platform, and a plurality of arc-shaped clamping plates distributed at equal angles are provided on the trough body. The plurality of arc-shaped clamping plates can expand outward or gather synchronously. When in use, the main shaft flange is placed on the trough body, and the second motor is started to drive the second main shaft to rotate and drive the first turntable to rotate. The rotation of the first turntable drives the plurality of arc-shaped clamping plates to gather synchronously to clamp and fix the trough body. Therefore, the present invention adopts a circumferential clamping method to fix the workpiece in all directions, and solves the problem that the unidirectional clamped workpiece is prone to shaking or offset due to impact force during the forging process. In addition, by controlling the degree of convergence of the plurality of arc-shaped clamping plates, flanges of different diameters can be adapted. There is no need to frequently replace the clamp, the adaptability is strong, and the production efficiency is improved.

[0016] In addition, when the first main shaft of the present invention rotates, it will drive the support frame to move vertically up and down to drive the forging hammer to move vertically up and down to forge the workpiece. At the same time, when the first main shaft rotates, it will drive the trough body to rotate intermittently to drive the main shaft flange placed on the trough body to automatically and intermittently shift positions during forging. By intermittently rotating the workpiece, it is ensured that the surface force of the main shaft flange workpiece is uniform during forging, and the flow direction of the metal fiber is optimized to ensure the forging quality. At the same time, it no longer relies on manual operation, and can be linked with the forging action in real time with high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

When the third turntable 30 rotates counterclockwise, the clamping plate 34 is embedded in the clamping groove 33 and can overcome the elastic squeezing of the wedge plate 38 on the first outer gear ring 31, driving the first outer gear ring 31 to rotate counterclockwise. When the third turntable 30 rotates clockwise, the first outer gear ring 31 is elastically squeezed by the wedge plate 38, and the clamping plate 34 squeezes the elastic paddle 35 to deflect it, and the first outer gear ring 31 remains stationary, so that the first outer gear ring 31 rotates intermittently and drives the groove body 15 to rotate intermittently, thereby causing the main shaft flange clamped on the groove body 15 to automatically rotate and transpose during forging. By intermittently rotating the main shaft flange workpiece and cooperating with the forging hammer 4 to forge, it is ensured that the surface of the main shaft flange workpiece is uniformly stressed during forging, and the flow direction of the metal fiber is optimized.
