2、 Innovation and advantages of Dema equipment
(1) Linkage mechanism feed system
Simple structure, stable performance, and low cost. A set of connecting rods can simultaneously drive two opposite rotary cutting wheels.
(2) Production efficiency increased by 4 times compared to traditional single station spinning machines
A spinning cutter wheel simultaneously processes two products, and a product is processed by two cutters wheels simultaneously (coarse and fine spinning). With the same processing time, the number of completed products increases to four.
(3) Overall finite element simulation
Through finite element analysis, improve the internal stress of each component to ensure that the dimensions of the parts meet safety requirements.
3、 Configuration and performance
(1) Mechanical structure
The main body of the machine tool uses a combination of high-strength castings, with a compact and reasonable structure, while optimizing the transmission path of rotary pressure. It adopts a closed-loop design, and the force point of rotary processing is closest to the sliding seat.
(2) System electrical appliances
Configure Beifu multi axis CNC system. The electrical system design and installation comply with national standards.
(3) Spindle unit
The spindle is driven by Feishi high torque servo, with a continuously variable speed function. The maximum torque of a single spindle reaches 10770Nm. The spindle box has good vibration absorption and stiffness.
(4) Spinning cutter wheel feed component
The radial feed of the rotary wheel adopts a parallelogram connecting rod structure driven by two hydraulic cylinders on top and bottom to feed synchronously. The connecting rod is made of high-strength alloy steel and ductile iron material.
