Problems solved by technology

The gross-to-net ratio of integral casting or integral forging is high, and the cost of blank production is high; when the roll is repaired and used for many times, and the diameter is reduced to the final scrap, the discarded material is more than 60% of the entire roll. Both methods will give The user causes a lot of waste and increases the production and use costs of the enterprise

Embodiment 1

[0027] A combined roll of a battery pole piece rolling mill, comprising a roll shaft 1 and a roll shaft 2 2 and a roll sleeve 3 fixedly connected to the roll shaft 1 and the roll shaft 2 . The roller sleeve 3 is a sleeve structure with a through hole at the center, and positioning notches 5 are arranged on both ends of the shaft sleeve 3. The positioning notch 5 is a short cylindrical hole concentric with the axis of the roller sleeve 3. The specific structure is as follows: figure 2 shown. Roller shaft one 1 and roll shaft two 2 are stepped shaft structures, including three parts: the roll neck, the positioning boss 6 and the connecting shaft section matched with the roll sleeve 3, which are sequentially connected together. The specific structure is as follows: image 3 shown. The shaft segment connected with the roller sleeve 3 and the inner hole of the sleeve 3 are connected by interference fit. The positioning boss 6 on the roller shaft 1 and the positioning notch 5 at ...

Embodiment 2

[0031] This embodiment is improved on the basis of Embodiment 1. In this embodiment, the outer circle of the positioning boss 6 is set as a conical surface. The specific structure is as follows Figure 5 shown. Set the inner hole of the positioning spigot 5 as a conical hole, and the specific structure is as follows Figure 4 shown. The taper of the outer conical surface of the positioning boss 6 is the same as that of the inner conical hole of the positioning notch 5, and the Morse taper is preferred. In this setting, the interference fit between the conical surface and the conical hole can transmit greater torque, and the centering between the roller shaft 1 and the roller shaft 2 and the roller sleeve 3 can be conveniently and accurately centered during assembly, that is, the roller shaft 1 The central axis of the roller shaft 2 coincides with the central axis of the hole of the roll sleeve 3, thereby ensuring that the overall coaxiality of the combined roll is good, ensu...

Abstract

The invention discloses a combined type roller of a battery pole piece rolling machine and belongs to the technical field of metallurgical equipment. The combined type roller comprises a roller shaft I, a roller shaft II and a roller sleeve fixedly connected with the roller shaft I and the roller shaft II, wherein the roller sleeve is a sleeve body structure with a through hole in the center; the roller shaft I and the roller shaft II are connected with the roller sleeve through interference fit; the roller shaft I and the roller shaft II are also fixedly connected with the roller sleeve via bolts. The combined type roller is simple in structure and easy to manufacture; compared with the conventional production manner, the workblank cost and the processing cost are greatly reduced; meanwhile, the combined type roller is easy to manufacture, high in overall strength and high in using performance.

Description

technical field [0001] The invention relates to a combined roll, in particular to a combined roll for a battery pole piece rolling mill, and belongs to the technical field of metallurgical machinery. Background technique [0002] The roll type used for rolling battery pole pieces is special, mostly with large diameter and short length of the roll body, small diameter and short length of the roll neck, and a large ratio of roll body diameter to roll neck diameter, commonly known as "short and thick roll". At present, the blank is made by integral forging or integral casting. The gross-to-net ratio of integral casting or integral forging is high, and the cost of blank production is high; when the roll is repaired and used for many times, and the diameter is reduced to the final scrap, the discarded material is more than 60% of the entire roll. Both methods will give The user causes a lot of waste and increases the production and use costs of the enterprise. Contents of the ...
