JQF-6 Autoclaved aerated concrete cutting machine is one of JQF-4.25 series product. It is a constant cutting developed from moving cutting. The machine is composed of longitudinal cutting machine and transverse cutting machine trolley and guid rail. And, the horizontal cutting machine has been modified from fixed swing, spring tension to frame swing and cylinder tension, and there is contact surface on the frame swing, which increase the service life, and remove the deform defect by the spring tension, it improves the cutting accuracy.
1.Cutting condition
When the casting blank is lift to the cutting trolley after turn 90° and de-mold, it will be moved to the work station of longitudinal cutting machine and transverse cutting machine to have six surface cutting for the casting blank. First, it will be cut 4 surfaces horizontally by the longitudinal cutting machine, and then it will be moved to the transverse cutting machine by the first trolley, and then cut vertically by the transverse cutting machine, and then it will be moved by the first trolley under the hanger which will lift it to the steam curring cavity and go back after the curring, meanwhile the cutting waste will be moved to the waste slurry mixing tank. It takes around 5 minutes to finish the cutting, the second trolley works together after the first trolley, it will move the cutting waste to the tank when the first trolley goes forward.
2.Single machine functio
Longitudinal cutting machine: It cut 4 surface for the casting blank (2 sides and upper and lower horizontal surface), the blank size after cutting is 600mm wide and 1200mm high, and it will be cut horizontally base on product required, and it will mill the tenon on the both end
Transverse cutting machine: It is used to cut the both end of the casting blank, the length will be determined base on the requirement, and it will cut vertically from upper to lower base on the thickness requirement
Trolley: It is used to move the casting blank to the cutting work station and move the cutting waste to the mixing tank
Waste clean trolley: It is a special trolley to move the cutting waste to the waste slurry mixing tank
The guid rail is used only for the trolley running.

4.Structure
All the main parts of the longitudinal cutting machine, transversed cutting machine and cutting trolley are made of square and rectangular steel tube, it has good rigidity, long service life and convenient structure, which is easy to install and adjust
Longitudinal cutting machine: It is composed of Longmen frame, beam, the vertical beam axis, cutting, slotting device, longitudinal steel wiring and wiring cutting tensioning device
Transverse cutting machine: It is composed of Longmen, transverse frame, frame beam, a guide shaft ( a guide sleeve for special lubricants bearings, without refueling ), transverse swinging device, vertical cutting transmission system ( lifting by the sprocket chain composition) and cutting wiring
Cutting trolley: It is composed of trolley body, cutting frame, wheels and running device, etc. It is driven by the speed reducer.
5.Work principle
The longitudinal cutting machine is tighten by the tension device and there is cutting wiring or cutter in the both sides, the front is used to cut the casting blank and the back i used to modified, in order to make ure the width is 600mm. The horizontal cutting has 5 grades, it cut in the angle of 39°48ˊ. The advantage is the cutting material will come down stably that there will no crack happen, and avoid any destroy. Each wiring has accurate scale to position, in order to make sure the product accuracy
The transverse cutting will start when the casting blank is put on the workstation. The program is that the vertical and horizontal cutting is synchronized. When it is cutting vertically, itis from upper to lower, the power is the reducer of K87-17.1-YEJ5.5-B31-0, the transmission reducer drives the chain wheel to make it cut from upper to lower. Transverse cutting is started by KD05-7.55-Y5.5-4P-M4-A+B, and it will have repeated motion with the help by the eccentric mechanism swinging device, and the cutting wiring in the both end will cut it to the required length and the middle part will be cut as the product required. The cutting wiring is tightened by the cylinder and the accuracy is positioned by the scale, the cutting time from upper to lower is 121.5 seconds
The cutting trolley is special used for moving the cutting material, it is driven by the reducer.
Our products are sold all over the world, you can rest assured.
