Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , the present embodiment proposes a vertical ring rolling machine with automatic loading and unloading, including a frame 1 on which a rolling roller 11 , a core roller 12 , a guide roller 13 and a measuring roller 14 are rotatably connected. The outer peripheral surface of the core roll 12 is provided with an annular die groove 121 for rolling the flange blank, and the end of the core roll 12 away from the frame 1 is integrally formed with a connecting shaft 122 (such as Figure 4 shown). One end of the frame 1 close to the core roll 12 is also provided with a supporting device 2 for supporting the core roll 12 and a loading and unloading device 3 for automatically loading and unloading the core roll 12 .

[0042] refer to figure 2 and image 3 , the support device 2 includes a base 21 , a support arm 22 , a discharge plate 23 ,...

Abstract

The invention relates to a vertical ring rolling mill capable of automatic feeding and discharging and relates to the technical field of hot forging machining. The ring rolling mill comprises a rack;a grinding roller, a core roller, a guide roller and a measuring roller are arranged on the rack; an annular die cavity used for rolling a flange blank is formed in the peripheral surface of the coreroller; a connecting shaft is coaxially and fixedly connected to the end, away from the rack, of the core roller; a supporting device and a feeding and discharging device are further arranged at the end, close to the core roller, of the rack; and the supporting device comprises a base, a supporting arm, a discharging plate and a first shaft sleeve; the feeding and discharging device comprises a feeding and discharging mechanism; the feeding and discharging mechanism comprises a first rotating rod, a second rotating rod and a feeding arm; and a driving device used for driving the supporting device and the feeding and discharging device is further arranged on the discharging plate. The supporting device and the feeding and discharging device can be directly driven to operate step by step through the driving device, automatic feeding and discharging of the vertical ring rolling mill can be achieved while a mandrel is protected, and the mill is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of hot forging processing, in particular to a vertical ring rolling machine with automatic loading and unloading. Background technique [0002] The ring rolling machine is also called rolling expanding machine or hole reaming machine. When processing forged flanges, the ring rolling machine is used to ream the hot forgings. According to the form of the frame and the position of the ring parts, the ring rolling machine can be divided into two types: vertical type and horizontal type. The vertical ring rolling machine is mainly composed of a frame, a rolling roller, a core roller, a guide roller and a measuring roller. Both the roller and the measuring roller are connected to the frame in rotation, and the rolling roller is connected to the frame in a sliding manner at the same time. When processing the flange, the flange blank is placed on the mandrel, and then the rolling roller is placed on the mandrel. W...
