The 720 type floor support plate forming machine is a specialized cold bending equipment for producing YX65-240-720 closed/YX51-240-720 open floor support plates. It effectively covers a width of 720mm and is suitable for hot-dip galvanized coils and aluminum zinc coated coils. It is widely used in high-rise steel structures, industrial plants, large supermarkets and other cast-in-place concrete floor bottom load-bearing steel plates. It has the advantages of high bearing capacity, high utilization rate and fast construction, and is the main model for medium and heavy-duty building floors.

Equipment structure composition

Uncoiler: 

• Passive/Hydraulic Uncoiler, capable of carrying 5-10 tons of coil material, with smooth feeding and constant tension.

Feed import platform: 

• guiding and correcting to ensure that the board enters in a straight line, preventing deviation and jamming.

Forming host: 

• 23-27 rows of precision rollers, layer by layer progressive forming, ensuring regular wave patterns and flat surface.

Punching device (optional): 

• Reserved bolt holes/connection holes, automated punching, precise positioning.

Hydraulic shearing system: 

• rear shearing design, dual guide column guidance, no burrs or deformation in the incision, high cutting accuracy.

PLC control system: 

• Delta/Schneider PLC+touch screen, set length, quantity, speed, fault self check alarm, frequency conversion speed regulation, single person on duty.

Discharge rack:

• Used for storing finished products, avoiding scratches on the board surface and facilitating collection and transportation.

Core Advantages

High strength whole machine design

• 400H steel frame+20mm thick middle plate, stress relief after welding, long-term heavy load without deformation or shaking.
• Φ 90mm solid formed shaft+imported bearings, with strong load-bearing capacity, fatigue resistance, and long service life.

Precision molding, stable quality

• The roller bearing steel is quenched and plated with hard chromium, which is wear-resistant and scratch resistant, does not peel off the paint, and has good forming consistency.
• The closed plate (YX65-240-720) has a wave height of 65mm, a three wave trapezoid shape, strong bearing capacity, high stiffness, and good concrete bonding; The opening plate (YX51-240-720) has a wave height of 51mm, light weight, convenient construction, and high cost-effectiveness.

High degree of automation, efficient and energy-saving

• PLC intelligent control, one click parameter storage, beginner can get started in 1 hour, single person on duty.
• Variable frequency speed regulation, smooth operation, low noise, energy saving of over 30%, daily output can reach 2000-3000 square meters.

One machine with multiple uses and wide adaptability

• Can switch between producing closed/open 720 floor slabs to meet different load requirements.
• Suitable for 0.8-1.5mm thick galvanized sheet, with high material utilization rate (closed about 59%, open about 72%).
