Description

Turnover blanking mechanism of coiling mould of coiling machine

Technical Field

The utility model relates to a rolling machine, in particular to a turnover blanking mechanism of a rolling die of the rolling machine.

Background

A rolling machine is generally used for rolling a sheet-like workpiece into a cylindrical workpiece by deforming the workpiece by extrusion. In the case of filter materials, it is often necessary to roll the filter sheet into a cylindrical shape. Referring to fig. 10, a conventional rounding machine for performing this process includes: the machine frame comprises a machine frame body, a lower die 1, a cylindrical die 2, a third cylinder, two side press blocks 183, a fourth cylinder, an upper press block 184 and a fifth cylinder, wherein the lower die 1 is fixedly arranged on the table top of the machine frame body and provided with a semicircular groove, the third cylinder drives the cylindrical die 2 to move up and down, the fourth cylinder drives the two side press blocks 183 to move left and right, and the fifth cylinder drives the upper press block 184 to move up and down. Namely, a filter screen piece needing to be rolled is placed on a lower die 1; the cylindrical die 2 is pressed down to press the filter screen sheet into a U shape by matching with the semicircular groove of the lower die 1; the two side press blocks 183 are close to the cylindrical die 2 and are matched with the cylindrical die 2, so that the filter screen sheet is primarily round; the upper pressing block 184 moves downwards, passes through the reserved position between the two side pressing blocks 183, is matched with the cylindrical die 2, and trims the junction of the two sides of the filter screen sheet to finish the rolling of the filter screen sheet.

The feeding can be directly finished by adopting the existing mechanical arm, but after the rolling is finished, the whole filter screen sheet is thinner and is completely sleeved on the cylindrical die and is tightly attached to the cylindrical die. When the mechanical arm is used for completing automatic discharging, the filter screen piece needs to be pressed, friction force between the filter screen piece and the filter screen piece is increased, and the filter screen piece can be peeled off from the cylindrical die. However, after the filter screen piece is stripped from the cylindrical die, the support and the shape of the cylindrical die are lost, and the filter screen piece is easy to deform on a manipulator, so that the processing quality is affected. Therefore, at present, a manual discharging mode is adopted, so that the rolled filter screen sheet can be completely taken down.
