Abstract
The utility model discloses a work roll velocity-hydraulic pressure driving device for bending machine and alignment machine, which comprises a motor, an oil pump, an oil cylinder and a work roll. Two sets of reverse rotating rational oil pumps with same model are driven by a motor of two-axle change-role and change-speed, which respectively drive the main oil cylinder connected with the bearing seats along the two sides of the work rollers through valve block. The utility model has the advantages of being simple in structure, good synchronization of work roll, lower oil temperature and saving energy.
Description
Technical field
The utility model relates to forging equipment, and is concrete relevant with veneer reeling machine arbor press working roll variable motion fluid pressure drive device.
Background technology
Existing forging equipment adopts variable pump as the working roll variable motion fluid pressure drive device of veneer reeling machine, arbor press; The employing twin shaft that has is stretched motor-driven high-pressure low-flow pump and low pressure and mass flow pump, drives two master cylinders respectively by two motors.Because variable pump or motor characteristic are softer, when the load of working roll two ends is uneven, influence being synchronized with the movement of two master cylinders.When adopting variable pump, movement velocity is relevant with load, and the load speed at one hour rating can fall; When adopting high-low pressure two table oil pumps, structure is complicated.Existing veneer reeling machine arbor press working roll variable motion fluid pressure drive device all has more hydraulic oil to do the idle loop campaign when oil pump zero load off-load, and power consumption is bigger.
Summary of the invention
In order to solve the problem that existing product exists, the utility model provides a kind of veneer reeling machine arbor press working roll variable motion fluid pressure drive device, and it has only less hydraulic oil to do the idle loop campaign when oil pump zero load off-load, reduces the oil temperature, and is energy-conservation; The movement velocity of two master cylinders improves the synchronized movement performance of working roll not with the master cylinder load variations.
For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of veneer reeling machine arbor press working roll variable motion fluid pressure drive device, comprise motor, oil pump, oil cylinder, working roll, it is characterized in that: stretch pole-changing windings but described motor is a twin shaft, and have two opposite same model quantitative oil pumps of rotation direction to be connected and installed with it; Two same model quantitative oil pumps can be combined into a duplex pump, and two same model quantitative oil pump rotation directions are identical, and twin shaft is stretched variable-pole-speed motor and be can be single shaft and stretch variable-pole-speed motor.
Variable-pole-speed motor can be provided with frequency converter.
Because the adjusting of flow realizes that by electrical motor gearshift the valve piece 3 of fluid pressure drive device can be simpler, the oil pump most of the time is unloaded, and the slack-off speed of motor when unloaded off-load has only less hydraulic oil to do the idle loop campaign, reduces the oil temperature, and is energy-conservation; Two same model quantitative oil pumps 2 are stretched variable-pole-speed motor 1 by same twin shaft and are driven, and working roll 6 synchronisms are good.
The beneficial effects of the utility model are, have simple in structure, advantage such as the working roll synchronism is good, and the oil temperature is low, and is energy-conservation.
Description of drawings
Fig. 1 is an enforcement schematic diagram of the present utility model.
Among the figure 1, twin shaft stretches variable-pole-speed motor, 2, quantitative oil pump, 3, the valve piece, 4, master cylinder, 5, bearing block, 6, working roll.
Specific embodiments
Below in conjunction with accompanying drawing the utility model is further specified.As shown in Figure 1, the utility model discloses a kind of veneer reeling machine arbor press working roll variable motion fluid pressure drive device, it is stretched two opposite 2, two same model quantitative oil pumps 2 of same model quantitative oil pump of rotation direction of variable-pole-speed motor 1 driving by twin shaft and drives the master cylinder 4 that is connected with working roll 6 two end axles bearings 5 by valve piece 3 respectively.Because the adjusting of flow realizes that by the motor pole-changing windings valve piece 3 of fluid pressure drive device can be simpler, the oil pump most of the time is unloaded, and the slack-off speed of motor when unloaded off-load has only less hydraulic oil to do the idle loop campaign, reduces the oil temperature, energy savings; Two same model quantitative oil pumps 2 are stretched variable-pole-speed motor 1 by same twin shaft and are driven, and working roll 6 synchronisms are good.
Two same model quantitative oil pumps can be combined into a duplex pump, and two same model quantitative oil pump rotation directions are identical, and twin shaft is stretched variable-pole-speed motor and be can be single shaft and stretch variable-pole-speed motor; Perhaps twin shaft is stretched the duplex pump of the opposite same model of two rotation directions of variable-pole-speed motor driving.
If variable-pole-speed motor 1 is provided with frequency converter, speed adjustable range is bigger, and energy-saving effect is better.
