Numerical-control double-roll veneer reeling machine with adjustable rounding diameter

Abstract

A two-roller bending machine capable of adjusting a bending diameter in a numerical control manner. An upper fixed roller (4) is fixedly disposed. A lower rubber roller (3) is disposed on two lower roller bearing supports (2) below the upper fixed roller (4). The two lower roller bearing supports (2) are fixed on two hydraulic cylinders (7) respectively. Sensor contact devices (6) of a sensor (5) are fixedly connected on the two lower roller bearing supports (2) respectively. A signal input end of a hydraulic control device (9) is connected to a hydraulic signal output end of a numerical control device (8). Workpieces of different diameters can be rolled with the same upper roller mould by changing a gap between the upper fixed roller (4) and the lower rubber roller (3). The sensor (5) can measure a current height of the lower rubber roller (3) in real time, that is, the distance between the upper roller (4) and the lower rubber roller (3). Real-time adjustment is performed through control of the hydraulic cylinders (7), so as to achieve the effect of rolling workpieces of different diameters with the same upper roller mould.

Description

Technical field: [0001] The invention relates to the technical field of plate rolling machines, in particular to a two-roll plate rolling machine with numerically controlled adjustment of the diameter of the rolling circle. Background technique: [0002] The two-roll plate rolling machine rolls the workpiece by pressing the rigid upper roll on the elastic lower roll to deform it. The upper rolls with different diameters cause different deformations of the elastic lower rolls, resulting in different diameters of the rolled workpieces. Therefore, to roll a workpiece with a diameter, a corresponding upper roll mold is made to achieve it. Affected by the above-mentioned traditional concepts, the two-roll plate rolling machine has always met the user's needs for rolling workpieces with different diameters by changing different upper roll molds. A large number of upper roller molds increase the production cost of the user. [0003] The current two-roller plate rolling machine on...

Affected by the above-mentioned traditional concepts, the two-roll plate rolling machine has always met the user's needs for rolling workpieces with different diameters by changing different upper roll molds. A large number of upper roller molds increase the production cost of users

[0003] The two-roll plate rolling machine currently on the market needs to replace different upper roll molds when rolling workpieces with different diameters during the application process. Because changing the mold requires a lot of manpower and material resources, and the work efficiency cannot be improved.
