Embodiment Construction

[0010] In the accompanying drawings, a drilled cooling calender roll includes a roll body 1 and a first roll shaft 2 and a second roll shaft 3 connected to both ends of the roll body 1 .

[0011] Wherein the roller body 1 is formed by one-time integral casting. During the casting process, the circumferential working roll surface of the roll body 1 is rapidly cooled to obtain a chilled layer on the surface.

[0012] Eighteen axial through holes 101 for cooling the circumferential work roll surface are opened at equal intervals on the roll body 1 with the same radius. A cooling water passage hole 104 is opened on the roller body 1 along its axis.

[0013] The first roller shaft 2 and the second roller shaft 3 are made of No. 45 steel.

[0014] The free end of the first roller shaft 2 is machined with a first bearing mounting surface 201, and the connecting end is coaxially processed with a first threaded connection surface 202 and a first joint surface 203 sequentially from th...

Abstract

The invention relates to a bored cooling calendaring roller, comprising a roller body as well as a first roller shaft and a second roller shaft which are respectively connected with the two ends of the roller body; wherein the roller body is provided with an axial through hole of a cooling working roller surface. The roller is characterized in that the first roller shaft and the second roller shaft are respectively provided with a cooling water channel hole which is communicated with a cooling water channel through hole on the roller body, the shaft body circumference surfaces of the first roller shaft and the second roller shaft are respectively provided with an annular water tank, the annular water tanks are respectively communicated with the cooling water channel hole by virtue of intercommunicating holes on the shaft bodies, the two ends of the axial through hole of the cooling working roller surface which is reserved on the roller body are respectively communicated with the annular water tanks on the shaft body circumference surfaces of the first and second roller shafts by virtue of oblique communicating holes, and the two end parts of the axial through hole are respectivelyprovided with a seal element used for sealing the axial through hole. The invention has the advantages of reasonable structure, and rapid repairing when being damaged, and is easy to process and reliable in use.

Description

technical field [0001] The invention relates to a device for manufacturing tires, in particular to a drilled cooling calender roll used in inner liner calenders, steel cord calenders, rubber mixers and other equipment. Background technique [0002] As we all know, large-scale equipment such as calenders and rubber mixing machines play a pivotal role in the tire manufacturing industry and are large-scale key equipment for tire production. Among them, the calender roller is an important component, which can calender high-temperature rubber materials, and its working environment is under high-temperature conditions. Therefore, the working surface of the calender roller body requires cooling treatment during work. The calender rolls currently used are all drilled cooling calender rolls, and their structure mainly includes a roll shaft and a roll body. The roll shaft and the roll body are cast in one piece. Adopt the rapid cooling method to obtain the surface chilled hard layer,...
