Professional AAC Block Vertical Cutting Machine For Fly Ash Block Plant

AAC Vertical Cutting Machine AAC Block Cutting Machine For Fly Ash Block Plant

Description:

JQF-4B autoclave aerated concrete cutter is a product of JQF-4 series, develop from moving cutting to constant power cutting, the cutter set is composed of four systems: longitudinal (horizontal) cutter, traverse cutter, cutting car ?and rails.?

1. Cutting mode:?

After the poured blocks are turned over for ninety degrees in the air, hoisted to the cutting car and stripped off the mould frame, then the cutting car carried it to the longitudinal cutter and the traverse cutter position, and the longitudinal cutter and the traverse cutter will cut them on six sides. First of all, the longitudinal cutter cut the block longitudinally and horizontally on four sides. When this operation is completed, the cutting car will carry the block stay under the traverse cutter position, so that the block is cut vertically on the remaining two sides by the traverse cutter. After cutting is finished, the block will also carried by the cutting car to the position under semi-finished hoisting tool , then the semi-finished hoisting tool will hoisted the block to the steaming and curing wheelbarrow. Then the car will go back quickly ,carry the block for the next cutting mould. Cutting cycle is less than seven minutes.

2. Function of each system

a) Longitudinal cutter : Its function is to cut the block on the car on four sides (the two lateral sides and the top and bottom surfaces). After cutting, the block will have a size of 600 mm wide and 1200 mm high. At the same time, horizontal cutting will be performed according to the specifications of the product (height or width). In addition, necessary keyways will be milled on both ends of the block.
b) Traverse cutter : Its function is to cut the block on two ends so that the block after cutting will be the require length. At the same time, vertical cutting (from tom to bottom) will be performed in the middle of the block according to the specifications and the thickness of the product.
c) The cutting car is a special carrier for carrying the blocks to the cutting position.
d) The rails are special tracks for the cutting car.

4. Structure:?

The main parts in the longitudinal cutter, traverse cutter and cutting car are all made of square or rectangular steel tubes. They feature high rigidity, long service lives, simple structure, easy installation and convenient adjustment.
a) The longitudinal cutter includes the following parts: portal frame, cross beam, vertical beam, cutting shaft, washing tank, longitudinal cutting wires, horizontal cutting wire, wire tensioning devices, etc.
b) The traverse cutter includes the following parts: portal frame, traverse cutting frame, bottom beam, guide shaft (its guide sleeve is a specially made lubricated bearing that needs no further lubrication), dual swinging devices for traverse cutting, drive unit for vertical cutting (up and down movement driven by sprocket and chain) and cutting wire.
c) The cutting car includes the following parts: bodywork, cutting frame, wheel and moving device. Its movement driven by speed reducer, use chain for the traction.

5. Operation

a) The cutting wires on the longitudinal cutter are stretched tight by the tensioning device so as to eliminate any possible slack. The front and rear cutting wires or
