Intelligent guide and guard device of large axle wedge cross rolling mill for rail transit

Abstract

The invention belongs to the technical field of shaft part plastic forming equipment, and particularly relates to an intelligent guide and guard device of a large axle wedge cross rolling mill for rail transit. The intelligent guide and guard device comprises guide and guard brackets, guide and guard bases arranged below the guide and guard brackets, and a guide and guard cross beam is arranged between the two guide and guard brackets. A plurality of guide and guard hydraulic cylinders are arranged on the guide and guard beam, telescopic rods of the guide and guard hydraulic cylinders are connected with a guide and guard sliding seat, guide and guard sliding grooves are formed in the inner sides of the guide and guard brackets, the guide and guard sliding seat is clamped in the guide and guard sliding grooves, and two adjusting hydraulic cylinders are installed on the front side of the guide and guard sliding seat. The upper ends of the two adjusting hydraulic cylinders are jointly hinged to a guide plate base. According to the intelligent guide and guard device of the large axle wedge cross rolling mill for rail transit, intelligent adjustment of the guide and guard device is achieved through a control system, the guide and guard hydraulic cylinders, the adjusting hydraulic cylinders, clamping hydraulic cylinders and a detection device, and the front opening, the rear opening and the height of the guide and guard device can be rapidly and intelligently adjusted according to product specifications, and the inclination angle of a guide plate can be manually adjusted.

Description

technical field [0001] The invention belongs to the technical field of plastic forming equipment for axle parts, and in particular relates to an intelligent guide device for a large axle cross wedge rolling mill for rail transit. Background technique [0002] Large axles are core components in the fields of high-speed rail, rail transit, and large-scale construction machinery, and the demand is increasing day by day. The traditional large-scale shaft parts are mainly prepared by forging with fast forging machines and precision forging machines. The fast forging process requires human intervention, long production cycle, low product precision, high energy consumption, and low efficiency. The subsequent production process requires heavy The amount of cutting is large, and at the same time, the metal flow line on the surface of the product is greatly damaged, and the mechanical properties of the product are reduced; the precision forging machine is completely monopolized by for...

Problems solved by technology

The traditional guide devices are installed on the fixed beams of the left and right racks of the cross wedge rolling mill. When the product specifications are adjusted, the opening and height adjustment between the front and rear guide devices are all adjusted manually. For the world's largest The standard cross wedge rolling mill has a huge guide device structure due to its huge rolling force. If the traditional guide device structure is adopted, the adjustment process is obviously very difficult and difficult to achieve, and it cannot meet the needs of rapid adjustment during product production. At the same time, the accuracy Difficult to guarantee
