The invention discloses a variable-frequency and variable-amplitude vertical vibration device of a block forming machine, and belongs to the technical field of design and manufacture for variable-frequency and variable-amplitude vertical vibration devices of block forming machines. The variable-frequency and variable-amplitude vertical vibration device comprises an electronic control portion and a mechanical portion. The electronic control portion comprises a touch screen, a programmable controller, a communication card and an alternating-current asynchronous servo driver. The mechanical portion comprises a vibration table and four vibration units. Each vibration unit comprises an eccentric shaft, a flexible coupling and a motor. Two rotation units of each group constantly keep oppositely and synchronously rotating under the control of the electronic control portion, and the vibration amplitude of the variable-frequency and variable-amplitude vertical vibration device can be changed by means of changing an included angle between two groups of rotation units during operation. The variable-frequency and variable-amplitude vertical vibration device has the advantages that the optimal vibration amplitude value and the optimal vibration frequency value can be selected according to forming requirements of concrete mixtures, so that the material application range can be expanded, and the quality of finished products can be guaranteed; the eccentric shafts are directly driven by the couplings to rotate, so that connecting assemblies such as eccentric shaft coupling gears of original equipment are omitted; problems of abrasion and damage of the assemblies such as the coupling gears due to frequent starting and stopping and high-speed violent vibration are solved.
Description
Technical field
The invention belongs to design and the manufacturing technology field of block machine Converting frequency & amplitude vertical vibration device.
Background technology
Block machine is a kind of machinery that makes concrete mix rapid densification moulding in die cavity under vibration and pressure synergy that relies on, and vibrating device is its important component part.Two the most basic parameters of vibrating device are " shaking frequently " and " amplitude ", and the coordination degree between the size of two parameters reaches has determined speed and the effect of concrete mix closely knit moulding in die cavity.Mobility and the granular size of the concrete mix that the selection of " shake frequently " and " amplitude " and die cavity are interior are relevant, and " frequency shakes " is too low, and shaping speed is slow, " shake frequently " too high, certainly will cause energy consumption to become the growth of how much multiples: " amplitude " is too small, and the coarse granule material shakes motionless, does not reach good jolt ramming effect, " amplitude " is excessive, vibration becomes jump and pounds, and makes the inner eddy current that produces of material, brings large quantity of air into, cause the building block internal structure loose, packing reduces.What generally the concrete mixing composition granule was large should use large amplitude, low frequency, on the contrary should use little amplitude, high-frequency." the shaking frequently " and " amplitude " value and the cooperation value between the two that each specific concrete mix are had to a best.
Mainly by shake table, one group or two groups, by gear coupling, eccentric shaft and prime mover three parts together form the vibrating device used on block building machine at present.Its course of work is: by electrical part, control prime mover according to the startup → low speed rotation designed → High Rotation Speed → program run stops operating, drive and make eccentric shaft rotation by mechanical transmissioning piece, force the shake table be integrated with the vibration unit rigid connection realize starting of oscillation → a little less than the shake technological requirement of the cloth → compacting of shaking by force → failure of oscillation standby.And the blocking device vibration device used at present exists following point.
1, prime mover continually in starting-slowly run-the periodic duty state of high speed rotating-stop, causing the waste of mass energy.
2, because amplitude is immutable, be difficult to select best amplitude according to the needs of concrete mix moulding, affected the result of use of forming machine, limited raw-material adaptability.
3, in order to make vibrating device produce the vertical orientation vibration, current vibrating device adopts gear that two eccentric shafts are coupled, and because frequent starting stops the vibration violent with high speed, gear very easily causes wearing and tearing and destroys.
Summary of the invention
According to the problems referred to above, the purpose of this invention is to provide a kind of Converting frequency & amplitude vertical orientation vibrating device of Controlled by micro computer, solve the problem that existing apparatus exists.
The present invention addresses the above problem taked technical scheme to be; By automatically controlled part and mechanical part, formed.Automatically controlled part is with touch-screen, programmable controller, address card and alternating current asynchronous servo-driver.Be interconnected to constitute automatically controlled part.According to technological requirement, programmable controller is programmed, by programming, the parameter of machine operation is shown on touch-screen, for the vibration unit parameter, " shake frequently " and adjust interface with the input of " amplitude ".Address card is the tie that connects mutual transfer of data between programmable controller and alternating current asynchronous servo-driver, and then the order that can carry out programmable controller is controlled four motor by technological process work to the alternating current asynchronous servo-driver.Mechanical part consists of shake table and four vibration units.Each vibration unit consists of eccentric shaft, flexible clutch motor.Below shake table with four eccentric pivot holes, in each eccentric pivot hole with eccentric shaft.At the connecting end of eccentric shaft and motor with flexible clutch.Eccentric shaft is connected with the output shaft of motor by flexible clutch.Is furnished with the alternating current asynchronous servo-driver on every motor.Four rotating units are divided into two groups, and wherein two is one group in inboard unit.Two outer side units are another group.Mechanical part of the present invention is arranged on the bottom of block machine.Divide and control two rotating units making every group and remain separately and synchronously rotate in opposite directions by electric control part, during work as long as the angle between changing two groups can be realized the variation of amplitude.Between two groups, the change of angle and speed is to lean against touch-screen manually to arrange, and setting is that the particle according to material, the difference of density size change, to reach the purpose that adaptability is wider.Under electric control part is divided control, remain that two groups of vibration units synchronously rotate separately in opposite directions, according to theory of simple harmonic; Horizontal side-to-side vibrations is cancelled out each other, the stack mutually of vibration vertically, thus make shake table remain vibrational state vertically, in order to obtain the exciting force of desirable above-below direction.When the angle between two groups of vibration units is 0 while spending, the exciting force addition, amplitude reaches maximum.Vibrating device place and the state that shakes by force.When angle is 180 while spending, exciting force offsets, and amplitude is zero.Now work system is in holding state.The wherein one group of vibration unit of take is benchmark, and another group vibration unit is realized the variation with respect to benchmark vibration unit 0-180 degree by the microelectronics technology of following.The present invention is simple in structure, reasonable in design.Can select best amplitude and the value frequently of shaking according to the needs of concrete mix moulding, enlarge the scope of application to material, guarantee the quality of manufactured goods.Adopt in addition shaft coupling directly to drive eccentric shaft to rotate, cancel original equipment eccentric shaft coupling wheel equijoin parts.Also eliminated thus because of frequent starting, stopped causing the wearing and tearing of the parts such as coupling wheel and the problem of destruction with the high speed high vibration.All gone up a level on automaticity and operation format.It is a kind of desirable block machine Converting frequency & amplitude vertical vibration device.
