Electric Spiral Pressure Machine Technology Parameters
Electric spiral pressure machine is a kind of machine tool power forming, which is driven by motor. It is widely used in many industries such as hardware, electronic components, toys, auto accessories, molds and mechanical parts. The operating principle of the electric spiral pressure machine is that the motor drives the rotation of the screw shaft, and the nut connected with the slide block rolls along the thread, exiting the slide block for reciprocating linear motion, driving the corresponding working process tool for reciprocating movement, and finally achieving the purpose of forming.
Electric spiral pressure machines come in various sizes, depending on the pressure they can produce. The measurable pressure range of the machine is generally 0.1-100kN, and its molding force is 0.03-500kN with a minimum pressure difference of 0.01MPa. In the case of two-point pressure, its maximum gap is 800mm and one-point pressure can reach 1000mm. The design of the machine should pay attention to the matching dimension between the slide block and screw, the size of the slide block, the shape of the fixed form, the machining accuracy of the form, the joint reliability between the molds, and the processing of stiffness.
The frames of electric spiral pressure machines are usually made of cast iron or steel weldments. The frame must have sufficient stiffness under maximum pressure and be able to withstand shock load and vibration. The size of the frame is determined according to the size of the slide block and screw. Also, for super large machines, it requires an auxiliary machine frame. The power head of the machine is usually made of high-precision screws and imported stepper motors. A high-precision worm wheel is mounted on the motor shaft, and bearings are mounted on the working end of the lead screw, which ensures the accuracy of the motion.
The main body of the electric spiral pressure machine is composed of screw, nut, machine frame, power head and connecting rod. The screw is used to drive the lower die driven by the power head. The power head is the power source of the machine, which includes the motor, the reduction device and the linked steel shaft. The transmission system of the power head includes reducer, clutch and high precision shaft. Therefore, the control accuracy of the electric spiral press is related to the performance of the power head system. The main function of the connected rod is to connect the two ends of the screw. The connecting rod transmits the force from the power head to the slide block through the nut.
In the working process of the machine, the pressing force provided by the power head should be suitable for the size of the machine. If the power of the machine tool is too large, it will increase the sparks of the machine, cause great damage to the machine tool, seriously reduce the accuracy of the machine and result in the breakage of the machine head. In addition, the choice of machine type and parameter selection depend on the characteristics of the workpiece to be formed. Large pressure, high accuracy and machine tools with higher load capacity can work on materials with a greater variety of properties.
In actual operation, we should ensure the safety of the operation, pay attention to the lubrication of the transmission parts, adjust the tension of the connecting rod in time, and observe the movement track of each part. In addition, in order to ensure the good operation of the electric spiral press machine, we must regularly carry out maintenance and repair, adjust the positioning and clamping device, periodically replace the fasteners, and clean the impurities inside the machine.
In conclusion, electric spiral pressure machine is a kind of operation forming machine with high power and accuracy. It is mainly used in mould manufacturing and mechanical parts processing. The user should choose the parameter of the machine according to the shape and size of the workpiece to be processed, and pay attention to the lubrication of the transmission parts and cleaning inside the machine. The maintenance and repair in time can make the machine run more smoothly and improve the accuracy of the workpiece.
