Detailed Description
Fig. 1 is a schematic structural diagram of the present invention; fig. 2 is a cross-sectional view of the roll body and shaft of the present invention.
As shown in the accompanying drawings 1 and 2, the coolable alloy cast iron roller comprises a roller body 1 and a shaft 2, wherein the shaft 2 is arranged at two ends of the roller body 1 respectively, the roller body 1 penetrates through a protective sleeve 3, the protective sleeve 3 is fixedly connected with the roller body 1 in a detachable mode, a positioning pin 4 is connected in a groove of the shaft 2 in a sliding mode, a spring is connected between the positioning pin and the groove, and a cooling water flow channel 5 is arranged in the roller body 1 and the shaft 2.
A plurality of connecting keys 6 are uniformly distributed on the shaft 2.
A plurality of cooling water flow channels 5 are arranged in the roller body 1, and all the cooling water flow channels 5 in the roller body 1 are communicated with the cooling water flow channels 5 in the shaft 2.
The roller body 1 is provided with a threaded hole, the protecting sleeve 3 is provided with a counter bore for installing a countersunk head bolt, and the protecting sleeve 3 is fixedly connected to the roller body 1 through the countersunk head bolt.
The protective sleeve 3 is a steel sleeve.
A shaft shoulder 7 is arranged between the roller body 1 and the shaft 2.
A plurality of stiffening plates 8 are distributed between the shaft shoulder 7 and the roller body 1.
The shaft 2 and the connecting key 6 are integrally formed.
The cooling water flows into the cooling water flow passage 5 in the roll body 1 from the cooling water flow passage 5 of one shaft 2 and then flows out from the shaft 2 at the other end to form a water flow circulation, thereby dissipating the heat of the roll body 1.
