Hydraulic forming machine for screw blade

Abstract

A hydraulic forming machine for a screw blade comprises a base, a frame, a bottom fixed tray, a hydraulic jack, a middle fixed tray, the screw blade, a top tray, vertical columns, a pointer, a ruler and the like. The hydraulic forming machine is characterized in that three vertical columns are welded to form the triangular frame, the ruler is arranged on one vertical column, the pointer is arranged on the top tray and can indicate the helical lead of the screw blade, the hydraulic jack is placed on the bottom fixed tray and a cushion block, the height of the hydraulic jack can be adjusted, the middle fixed tray is horizontally welded in the middle of the frame, the screw blade is fixed between the middle fixed tray and the top tray through bolts, a piston rod of the hydraulic jack passes a central through hole of the middle fixed tray, then contacts with the top tray, is abutted to the top tray and moves upwards when the hydraulic jack operates, so that the screw blade is stretched and formed, and needed jacking force can be provided by selecting the matched hydraulic jack according to the thickness of the screw blade, so that the shape of the obtained blade is standard. The hydraulic forming machine is low in production cost, simple and convenient in use method, suitable for machining or mechanical maintenance enterprises and quite wide in application prospect.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a hydroformer for auger blades. Background technique [0002] Screw conveyors or mixers have a very wide range of uses. Among many screw conveyors or mixers, the auger blades are the most important core components. Tools such as chain hoists, sledgehammers, hand hammers, crowbars, spreaders, and brackets force the blades to be stretched, or heat stamped, and then weld the blades to the central shaft, but these methods are used for processing. It is laborious and time-consuming, and the drawn auger blades are very irregular, and the working performance is very unstable. For ultra-thick auger blades with a thickness of more than 10mm, if you still use cranes, chain hoists, sledgehammers, and hand hammers It is difficult to stretch the auger blades into shape with relatively simple tools such as crowbars, spreaders and brackets. Comparatively, the auger blade hydroformer that can ...
