The die pressing method of the frame-shaped coil of the motor comprises the following process steps of: (1) die pressing and heating the coil: coating a demoulding belt on the coil after packing over the ground, placing the packed coil on an adjustable pressing die, switching on current or an electric heating tube from the down-lead of the frame-shaped coil to heat the die and enable the lead of the coil to heat, and clamping the down-lead with a clamp; (2) pressurizing a linear mould weight: placing the linear mould weight, and pressurizing the linear mould weight with a caran; (3) raising temperature, pressurizing and keeping warm: powering up for heating to raise the temperature of the coil to 160-180 DEG C, pressurizing the linear mould weight with the caran, and keeping warm for 2-3 hours; (4) reducing temperature and dropping die for the coil: reducing the temperature to 100-120 DEG C, and dropping the die; and (5) cooling and shaping: placing the coil after reducing the temperature and dropping the die into a cold mould, cooling and shaping. The invention has the advantages of simple process, time and labor saving, improvement of electric property and dielectric strength of the coil, cost reduction, high processing efficiency, good die pressing quality of the coil and the like.
Description
Technical field
The invention belongs to the through-flow machine technical group field, particularly relate to a kind of compression molding method of motor frame coils.
Background technology
At present; The box coil molding die process technique; The coil that finishes of wrapping is over the ground wrapped demoulding band, carries out preheating, adjusts the control cubicle technological temperature time, then coil is put on the pressing mold, adopt screw rod to compress mode to advance in the high temperature special use baker and carry out mold pressing with card is blue, for coil; Heat belongs to outer heating from the coil surface to the coil inside.In operating process, particularly the box coil mold pressing of 10500 volts of utmost points is prone to the coil ageing imperfection over the ground the time; Insulation integrity and density are poor, influence coil electric performance and dielectric strength, coil puncture rate height, and this manual manipulation method; The sectional dimension deviation is bigger, and the coil die mould finishes when coming out of the stove, poor stability, easily occur scalding, and exists operator's labour intensity big; Problems such as energy and material is wasted, and manufacturing cost is high, and production efficiency is low.
Summary of the invention
The present invention provides a kind of compression molding method of motor frame coils for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide that a kind of to have technology simple, easy to operate, time saving and energy saving, improve coil electric performance and dielectric strength, reduce cost coil die stamping Functionality, quality and appealing design, the compression molding method of motor frame coils of characteristics such as working (machining) efficiency height.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of compression molding method of motor frame coils; Be characterized in: box coil mold pressing processing comprises following processing step: 1) coil die stamping heating: wrap up the coil that finishes over the ground and wrap demoulding band; Be put on the adjustable pressing; Directly feed electric current or electrothermal tube to mold heated from frame coil lead, make the winding wire heating, step up lead-in wire with anchor clamps; 2) straight line foundary weight pressurization: put the straight line foundary weight, the straight line foundary weight is pressurizeed with card is blue; 3) intensification pressure heat-preserving: when adding electric heating and making coil be warming up to 160 °-180 °, blue with the pressurization of straight line foundary weight, be incubated 2-3 hour with card; 4) coil cooling stamping die: when being cooled to 100 °-120 °, stamping die; 5) cooling and shaping: coil cooling stamping die rear defence is gone into cooling and shaping in the cold mould.
The present invention can also adopt following technical scheme: described compression molding method of motor frame coils is characterized in: add electric heating and adopt the PLC control cubicle to control automatically.
Described compression molding method of motor frame coils is characterized in: step up wire clamp and adopt hydraulic cylinder to step up mode.
Scalable mould is over the ground adopted in box coil mould pressing process processing, regulates two by iron runner angle, is fixed on the scalable guide rail then with verification model over the ground.Be provided with positioner by box coil on the iron.Can adopt design two end plates supporting construction to topotype.
Advantage and good effect that the present invention has are: compression molding method of motor frame coils has been owing to adopted brand-new technology scheme of the present invention, thereby has following characteristics: 1. good, the coil of electric property and dielectric strength adopts interior heating, safe.
2. energy-saving and cost-reducing, raising product inherent quality.
3. easy to operate, time saving and energy saving, alleviated operator's labour intensity.
4. realize one module multiple usages, economized on the use of funds, reduced cost, helped the seriation management of mould.
Description of drawings
Fig. 1 is a frame-shaped coil of motor molding die process technique schematic flow sheet of the present invention.
