Hydraulic rounding machine for hollow wooden column

Abstract

The invention discloses a hydraulic rounding machine for a hollow wooden column. The hydraulic rounding machine comprises brackets, wherein the upper parts of circular separation blades are fixed on the brackets; two circular tubes are arranged below the brackets; the circular tubes pass through the separation blades; support arm hydraulic cylinders are fixed on the side walls of bottom transverse beams; one end of each movable support frame and one end of each separation blade are fixed on the two circular tubes respectively, and the other ends are connected together through pins; annular brackets are symmetrically fixed on the two circular tubes at equal intervals in the axial direction; strap fixing frames are fixed on the annular brackets; hydraulic pulling cylinders and belt fasteners are fixed at the two ends of the brackets respectively; one end of each tension belt is fixed on each belt fastener, and the other end of each tension belt is fixed with a U-shaped claw of each hydraulic pulling cylinder; a hydraulic electric control system consists a motor gear pump, a reversing valve, an overflow valve and a hydraulic cylinder. The hydraulic rounding machine is stressed uniformly, is not limited by the diameter or the length of the hollow wooden column, has the advantages of high pressurizing speed, convenience in operation and capability of automatically supplementing pressure, and can be widely used for making carrying round columns of various sizes.

Description

[0001] Technical field: The present invention relates to special equipment for woodworking, especially the equipment for rounding hollow wooden columns. Background technique: [0002] Currently widely used load-bearing columns, especially large-scale load-bearing columns are generally made of reinforced concrete. This type of load-bearing column is characterized by strong bearing capacity and is suitable for most construction fields. However, some artistic buildings require load-bearing columns to be aesthetically pleasing. And the lighter large load-carrying hollow wooden column is not applied at present because there is no feasible processing method, and a kind of forming equipment of designing a hollow wooden column to process the hollow wooden column has become an urgent need. Invention content: [0003] In order to overcome the deficiencies in the prior art, the present invention designs a hollow wooden column rounding machine for producing large load-bearing hollow woo...
