Plate rolling machine work roll

Abstract

The invention relates to a working roll of a veneer reeling machine, belonging to the technical field of the working roll of the veneer reeling machine. The working roll of the veneer reeling machine is mainly characterized in that the middle part of the working roll is of a cylindrical shape of which the length is 60%-70% of the total length of a working roll 1; and the two ends of the working roll are conical, and the conical degree is 1: (2-3). By using the working rolling, the manufacturing cost of the whole veneer reeling machine can be effectively reduced, and a small-diameter cylindrical workpiece can be coiled and formed on the veneer reeling machine, thereby enlarging the use rang of the veneer reeling machine; the working roll has the advantages of small structure and low cost; and when in use, the improved working roll can be connected with the bearing body of the veneer reeling machine, and the structure of the shaft neck of the improved working roll is as same as the structure before improvement.

Description

Technical field [0001] The invention relates to the technical field of work rolls of a plate bending machine. Background technique [0002] The work rolls of the currently used plate rolling machines mostly adopt a cylindrical structure, and the plate rolling machine realizes the rolling of the plate through the position change of the work roll and its rotation movement. This cylindrical work roll structure has the following defects: for the plate rolling machine product, when the plate is rolled, the rolled cylindrical workpiece is generally wrapped on a certain work roll of the plate rolling machine, so it is required The work roll of the bending machine must have sufficient rigidity and strength. When the diameter of the workpiece to be rolled is small, especially when the diameter of the roll is less than or equal to the diameter of the work roll, it cannot be achieved. In this case, most of the workpieces are produced by pressing multiple arc-shaped workpieces on a press, ...

Problems solved by technology

This cylindrical work roll structure has the following defects: for plate rolling machine products, when the plate is rolled, the rolled cylindrical workpiece is generally wrapped on a certain work roll of the plate rolling machine, so it is required The working rolls of the plate rolling machine must have sufficient rigidity and strength

Therefore, the workpiece processing technology is complicated, the cost is high, and the quality is poor.

Secondly, when the rolled workpiece requires a larger working capacity of the plate rolling machine, it is necessary to ensure that the diameter of the working roll meets the requirements for stiffness and strength. At this time, the working roll diameter of the plate rolling machine needs to be larger, otherwise when When the plate rolling machine is working, due to the excessive load of the work roll, there will be a certain deflection deformation, which will affect the working accuracy of the workpiece rolling

For the plate rolling machine, the work roll is the main factor affecting its product cost, so the manufacturing cost of the plate rolling machine is relatively high under this condition
