Abstract
The invention discloses a pipe expander. The pipe expander comprises a machine frame, a power seat, a flaring seat, first lead screws, a first driving motor, a programmable logic controller (PLC), second lead screws and a second driving motor, wherein the power seat and the flaring seat are arranged on the machine frame and can move up and down; the first lead screws and the first driving motor are used for controlling the power seat to move up and down; the second lead screws are used for controlling the flaring seat to move up and down; the second driving motor is used for driving the second lead screws. By the adoption of the pipe expander, the problems that according to an existing pipe expander, products are machined in a high-power mode, single-motor driving is adopted, and therefore the motor power is high, and the cost is high are solved; meanwhile, the problems of a double-station structure that the structure is complex, and the efficiency is low are solved; the structure is simple, the efficiency is high, the cost is low, and the pipe expander can be widely applied to the field of pipe expanders.
Description
Technical field
The present invention relates to electric tube expander field, especially relate to the electric tube expander of a kind of same station substep expand tube and enlarging.
Background technology
Because converted products is too large in existing servo electric tube expander equipment, required expand tube power and enlarging power is caused also to increase accordingly.This just make traditional servo electric tube expander need be equipped with very powerful motor, and these powerful servomotors generally all need customization and volume is very large.Due to the particularity of motor in the manufacture process of equipment, cause the production delivery date of equipment additionally to extend and additionally increase with equipment volume.
The swollen old structure electric tube expander operation principle expanding one is as shown in Figure 1: enlarging adjustment motor 108 drives enlarging to beat fast 104 by trapezoidal screw 105 and moves up and down and carry out position adjustment, then drives power seat 102 to carry out expand tube by mair motor 101 by ball screw 103.When power seat 102 move downward carry out expand tube time, power seat 102 run to beat with enlarging fast 104 contact after, enlarging is beaten fast 104, by trapezoidal screw 105, power is passed to flare seat 106.Flare seat 106 carries out enlarging after first overcoming the cylinder force of balance cylinder 107.Because expand tube process is also being carried out in flaring process, now all enlarging power and expand tube power all need mair motor 101 to export.Because enlarging power adds expand tube power very greatly, the now corresponding height also just needed very of the power of output motor 101.
In order to solve the excessive problem of power of motor, so there is the double electric tube expander that expand tube and enlarging are separately carried out at two different stations, it arranges a rotating disk in the below of flare seat, drive heat exchanger unitary rotation, this type of electric tube expander owing to adding a few procedure, complex structure and expand tube efficiency is seriously reduced.
Summary of the invention
The object of this invention is to provide a kind of electric tube expander, solving existing same station electric tube expander when carrying out large Product processing, required motor power is large, and the problem that cost is high, solves existing double electric tube expander complex structure, inefficient problem simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric tube expander, comprises frame, is arranged on power seat moving up and down and flare seat in frame, the first screw mandrel that control power seat moves up and down and the first drive motors, PLC; Also arrange and control the second screw mandrel that flare seat moves up and down and the second drive motors driving the second screw mandrel dynamic.
For anti-stopping power seat and flare seat are moved beyond limit value, described frame is respectively arranged with the lead limit switch of restricted power seat and the upper and lower stroke of flare seat.
Preferably, the described first dynamic motor and the second drive motors are servomotor.Described second screw mandrel is ball screw.
Further, described PLC controls the running of the first drive motors and the second drive motors, PLC regulates the initial position of power seat and flare seat according to the height of expand tube, then controls the first drive motors operation and drives power seat heat exchanger copper pipe to carry out expand tube; After the operation of power seat puts in place, PLC controls the second drive motors operation and drives flare seat heat exchanger copper pipe to carry out enlarging; After enlarging completes, PLC controls the first drive motors and the reversion of the second drive motors, drives power seat flare seat to get back to initial position.
Beneficial effect of the present invention: respectively power seat and flare seat are driven under the control of PLC by arranging two drive motors on same station, avoid existing electric tube expander to carry out expand tube and enlarging under the driving of same motor simultaneously, the problem that required motor driving force is large, reduces the purchase cost of equipment and improves the service life of equipment.And this Dual Drive electric machine structure is compared with existing double, structure is simple, and operational efficiency is high.Described drive motors adopts servomotor, more convenient control, described ball screw comparatively trapezoidal screw, and the speed of service is fast, and precision is high.Described limit switch, for the protection of power seat and flare seat, prevents it from running the scope exceeding setting.
Below with reference to drawings and Examples, the present invention is described in detail.
Accompanying drawing explanation
Fig. 1 is the front view of existing electric tube expander.
Fig. 2 is front view of the present invention.
Fig. 3 is rearview of the present invention.
Detailed description of the invention
Embodiment, as shown in Figure 2 and Figure 3, a kind of electric tube expander, comprise frame 7, be arranged on power seat 2 moving up and down and flare seat 5 in frame 7, control the first screw mandrel 3 that power seat 2 moves up and down and the first drive motors 1 driving the first screw mandrel 3 to move, control the second screw mandrel 6 that flare seat 5 moves up and down and the second drive motors 4 driving the second screw mandrel 6 to rotate.Control the PLC 8 of the first drive motors 1 and the second drive motors 4.Described frame 7 is also respectively arranged with the lead limit switch 9 of restricted power seat 2 and flare seat about 5 stroke, anti-stopping power seat 2 and flare seat 5 run the scope exceeding setting, ensure the security of operation of machine.
Described first drive motors 1 and the second drive motors 4 are servomotor, the revolution of described PLC setting servomotor each run, and ensure that expand tube and enlarging put in place.Described second screw mandrel 6 is ball screw.
Described PLC 8 controls the running of the first drive motors 1 and the second drive motors 4, PLC 8 regulates the initial position of power seat 2 and flare seat 5 according to the height of expand tube, then controls the first drive motors 1 operation and drives power seat 2 heat exchanger copper pipe to carry out expand tube; After power seat 2 operation puts in place, PLC 8 controls the second drive motors 4 operation and drives flare seat 5 heat exchanger copper pipe to carry out enlarging; After enlarging completes, PLC 8 controls the first drive motors 1 and the second drive motors 4 reverses, and drives power seat 2 and flare seat 5 to get back to initial position.
Instant invention overcomes existing electric tube expander high-power converted products list motor drive motors power large, the problem that cost is high, meanwhile, overcomes double complex structure, inefficient problem.
