Multi-cone roller rolling machine

Abstract

The invention provides a rotary forging press with multiple conical rollers. The rotary forging press comprises a machine body, a conical roller assembly, a mold stripping assembly, a sliding guide assembly and a rotary driving device, wherein the machine body comprises an upper cross beam and a lower cross beam, and stand columns arranged among the four corners of the upper cross beam and the lower cross beam; the sliding guide assembly comprises a sliding block, guide rails and sliding driving devices, the sliding driving device is arranged on the upper cross beam and is connected with the sliding block, and the guide rails are arranged on the stand columns respectively and are matched with the four corners of the sliding block; the conical roller assembly comprises a plurality of conical rollers, and the conical rollers are sequentially and horizontally arranged at the bottom of the sliding block through supports; and the mold stripped assembly is arranged at the top of the lower cross beam and is connected with the rotary driving device. According to the rotary forging press with the multiple conical rollers, a metal disk piece and a metal round billet with large diameter-thickness ratio can be formed by rotary forging through the multiple conical rollers, wherein the diameter can reach more than 10 m, the thickness can reach below 100 mm, and the ratio of the diameter to the thickness is more than 100.

Description

technical field [0001] The invention belongs to the technical field of forming equipment for multi-roller swing rolling of metal disk parts and metal round blanks, and in particular relates to a multi-conical roll swing rolling machine. Background technique [0002] With the improvement of the safety level of large containers such as nuclear power and chemical industry and the development of technology, it is necessary to make the overall head of more than 6 meters. At present, the production methods of disc parts with a diameter of less than 5m and large diameter / thickness disc (ring) parts It is through repeated partial upsetting of a flat plate, or expanding into a cylinder through horse frame expansion into a square piece, and then cutting it into a disc piece. These two forming methods need to be heated many times, and the forming efficiency is low and the cost is high. The process is complex, the surface of the formed part is uneven, the amount of cutting processing is...

Problems solved by technology

[0002] With the improvement of the safety level of large containers such as nuclear power and chemical industry and the development of technology, it is necessary to make the overall head of more than 6 meters. At present, the production methods of disc parts with a diameter of less than 5m and large diameter / thickness disc (ring) parts It is through repeated partial upsetting of a flat plate, or through a horse frame to expand into a cylinder and then unfold it into a square piece, and then cut it into a disc piece. These two forming methods need to be heated many times, the forming efficiency is low, the cost is high, and the process The process is complex, the surface of the formed part is uneven, the amount of cutting is large, and the utilization rate of the material is low, and for metal disc parts with large diameter / thickness (diameter can be more than 10m, thickness can be less than 100mm, diameter / thickness is greater than 100mm) and metal round blanks, no studies have been done on monolithic forming equipment
