Description

Technical field

The invention relates to vertical type vibropresses with hydraulic vibrators and methods of vibropressing with their use.

State of the art

One of the most famous vertical type vibrating presses are the vibrating presses of the American company Besser. Closest to the proposed objects of the invention - vibropress and method of vibropressing with its use - are the device and method according to US patent No. 4978488 (1990) with the inclusion in the text of the description of links to US patent No. 4395213 (1983).

The described vibrating press contains a vertical bed with racks-guides, a drive unit for a shaft with fists, reciprocating rollers for the slider with punches and for the matrix, open from above and below, and with a vibrocompressed mixture, the matrix pallet, the balancing cylinders of the slide and the matrix, matrix pressing devices with a pallet to the vibrating table, vibrators of the vibrating table and its shock absorbers.

In the indicated vibrating press, unbalanced vibrators driven by electric motors are used. The vibration frequency (usually 25 or 50 Hz) is set using electric motors with a rotation speed of 1500 or 3000 rpm, which does not change during the cycle, the amplitude during the vibration pressing cycle is set according to the program by rearranging unbalanced masses. For this, the vibrator shaft may not be stopped during the vibrocompression cycle, and the unbalanced masses can be rotated by the programmable pneumatic drive built-in in the cavity of the drive shaft of the predominantly programmed pneumatic drive.

The vibrator shaft is rotated at an almost constant angular velocity (constant speed). The vibration amplitude can be changed according to the program by moving the counter-balance, which eccentrically causes vibration, and the engine continues to rotate during the entire product pressing cycle, after which the drive motor of the system is stopped.

The continuously rotating shaft assembly comprises a fixed eccentric part and a rearranged counterbalanced mass. The shaft assembly has a cylinder with a piston attached to the counterbalanced mass for the rotational movement of the load relative to the fixed eccentric part. The mass returns to its original position by a spring with a predetermined force level.

The use of unbalanced vibrators limits the possibilities of effective vibrocompression of large-volume products and especially products from new polystyrene-concrete materials for the preparation of modern products of architectural and building blocks, where in addition to cement-sand working mixtures, polystyrene-concrete working mixtures and other materials are required that require molding to be optimized the application of a variable during a cycle of vibration exposure to the working mixture with variable vibration parameters: frequency and amplitudes roperemescheny and specific vibration forces.

The vibropress indicated in the American patent is also used to implement the method of vibrocompression with programmable amplitude during the stages of the vibrocompression cycle and an almost constant frequency of vibrations. According to this method, the cement-sand mixture (hereinafter the working mixture) is fed into the matrix open on the top and bottom, located on a pallet. During the molding of the product, the working mixture is acted upon from above by the static force that the forming punches create and from below by dynamic vibrations that are created by vibrators acting on the pallet with the matrix installed on it. After the molding is completed, the force and vibration effects are stopped, the punches and die are removed, and the products on the pallet are transferred for final hardening. The limitation of the method is the presence of only two stages of the vibrocompression cycle and the regulation of almost only one parameter of the amplitude of the vibratory displacements, which significantly narrows the functionality of the method, does not make it possible to optimize the process by changing the frequency and specific forces of vibrations, reduces the efficiency of vibrocompression and the quality of the resulting products.

Disclosure of invention

An object of the invention is to increase the efficiency of the vibropressing process and quality (high density values up to 60% and equal density up to 95 ... 98%) of concrete products with different types of impurities (sand, polystyrene, etc.), different volumes and nomenclature . For the manufacture of modern products, in addition to cement-sand working mixtures, polystyrene-concrete working mixtures and other materials are used that require, for optimization of the molding process, the application of an alternating during three stages of the vibration cycle on the working mixture with variable vibration parameters: frequency in the range of 10 ... 100 Hz, with an amplitude of specific forces of vibrations of 10 ... 200 kPa and an amplitude of vibration displacements of 1 ... 3 mm.

In the inventive device of a vibropress and a method of vibrocompression using it, this problem is solved by using the original hydraulic vibrator built in the vibrating table with a hydraulic exciter of vibrating pulses, which provides variables that are remotely adjustable according to the program, the frequency, the amplitude of movement and the magnitude of the specific force on the product and its vibration compaction for three stages molding process: filling the mold matrix, preliminary vibration compaction and final vibration compaction.

A vertical type vibropress for vibrocompressing an architectural and construction mixture contains a bed, a central element in the form of a forming matrix with rods installed with the possibility of vertical movement and open at the top and bottom, having at least one cavity with an opening for a compacted architectural and construction mixture. Also, the vibrating press contains a means of compressing the action on top of the architecturally-building mixture in the matrix, made in the form of a slider having vertical movement with punches corresponding to the holes in the matrix, and means of vibrating the bottom on the architecturally-building mixture in the matrix, made in the form of a vibrating table with between it and the matrix is a pallet and a drive unit. There are also drive devices for moving the slider with punches and a matrix in the form of separate fists interacting with the response rollers, made with cyclic control from a common drive motor with a mechanical transmission system to the fists. There are also auxiliary units in the form of clamping levers for pressing the matrix with the pallet to the vibrating table, mass balancers of the slide with punches and a matrix with rods and clamping levers and shock absorbers installed between the vibrating table and the bed.

The proposed vibrating press is characterized in that the drive device of the vibrating table is made in the form of a hydraulic vibrator integrated in the table, which is configured to change the vibration parameters by adjusting the frequency, amplitude of vibration displacement and amplitude of the specific force of vibration exposure according to the program.

The hydraulic vibrator contains a power hydraulic cylinder, a hydraulic pulse exciter, a cyclic accumulator, a pump station and a system of hydraulic channels. The hydraulic exciter contains a piston valve with a return spring and a brake plunger and a ball servo valve with a pressure plunger and a spring. Moreover, the piston valve is configured to automatically open at high pressure the fluid at the junction of the inlet of the hydraulic exciter, the cyclic accumulator and the discharge outlet of the pumping station and automatically close at low pressure, as well as providing during the automatic opening of fluid under pressure from the cyclic accumulator to the power hydraulic cylinder , and during automatic closing - filling the cyclic accumulator with liquid from the pumping station to form in the hydraulic power cycle nucleus fluid pulses to vibration impact. The piston servo valve is equipped with a spring made with the possibility of controlling its compression by means of a remote and / or programmed servomechanism to control the fluid pressure, the opening and closing times of the piston valve to change the frequency, amplitude of vibration displacement and amplitude of specific force of vibration exposure.

To expand the capabilities of the vibrating press, the pump station may also be able to remotely and / or programmatically control the fluid supply and pressure at its outlet.

Using such a vibrating press with a built-in hydraulic vibrator and with such possibilities for controlling vibration parameters, it is proposed to implement a method of vibrocompressing an architectural and construction mixture, including the step of filling the working architectural and construction mixture in the cavity of the vibrating press matrix, which is carried out with a vibration effect on the specified working mixture from the vibrating press, forming of the last product by compressing the working architectural and construction mixture from above with vibro-punches ca and vibration impact on the vibration table below. In this case, the molding of products is carried out in two stages, on one of which a preliminary vibration compaction of the working architectural and construction mixture is performed, and on the other, the final vibration compaction. At the stage of filling the working mixture and the stages of molding products from it, the vibration parameters are changed by adjusting the frequency, amplitude of the vibration displacement and the amplitude of the specific force of the vibration effect according to the program, the values of which at the mentioned stages are set depending on the composition of the working mixture. Moreover, at the stage of filling the working mixture, the frequency of vibration exposure is set to a component of 80 ... 100% of the maximum value, and the amplitude of vibration displacement and the amplitude of the specific force of vibration exposure are set to 20 ... 50% of the maximum value, and at the stages of preliminary and final vibration compaction, the frequency is set to a component, respectively 50 ... 80% and 10 ... 50% of the maximum value, and the aforementioned amplitude of vibration displacement and the amplitude of the specific force of vibration exposure - components of 50 ... 70% of the maximum the value at the stage of preliminary vibration compaction and 70 ... 100% of the maximum value at the stage of final compaction.

The vibration frequency is set mainly in the range of 10 ... 100 Hz, the amplitude of the specific force of vibration is set in the range of 10 ... 200 kPa with an amplitude of vibration displacements of 1 ... 3 mm (it is more efficient to provide such ranges of vibration parameters with the proposed vibrating press with a built-in hydraulic vibrator than with an unbalanced vibrator).

Figure 1 does not show the clamping levers with rubber cylinders for pressing the matrix 11 with the pallet 13 to the vibrating table 14; cylinders and shock absorbers 14.

The vibrating press is made of a vertical type with a two-rack frame 1, in the upper part of which there is a drive unit 2 consisting of an electric motor, gear transmission No. 1, a friction disk clutch-brake, an intermediate shaft, which is connected by a gear transmission No. 2 to the main shaft 3. On the main shaft 3, the central 4 and two lateral 8 drive cams are fixed, profiled in accordance with the cycle for moving the slide 6 with punches fixed on it, and the matrix 11. The central fist 4 interacts with the roller 5 mounted on the crawl e 6. The slider 6, under the influence of the central fist 4, can move vertically in the guides of the bed 1. The mass of the slider 6 with the punches is balanced by pneumatic piston balancing cylinders 7, the rods of which are fixed on the slider 6, and the force developed by the balancing cylinders 7 is sufficient for constant pressure of the roller 5 to the fist 4 and the return stroke of the slider 6 to its original upper position.

Two lateral fists 8 interact with the matrix 11 using rods 10 with rollers 9. At the bottom of the frame 1 there is a vibration table 14, which has the ability to move vertically in guides (not shown) within the amplitude under the influence of vibrations. On the vibrating table 14, a pallet 13 is placed on top, and a matrix 11 is opened on it. The matrix 11 is pressed tightly against the pallet 13 and the vibrating table 14 with clamping levers (not shown) under the influence of piston-free rubber cylinders (not shown). The bottom of the vibration table 14 is based on cylinders and shock absorbers (not shown) mounted on the frame 1 to reduce noise and the effects of vibration on the frame 1. The mass of the matrix 11, two rods 10 and two clamping levers is balanced using pneumatic piston balancing cylinders 12, fastened with bed 1. The power of the balancers 12 provides a constant pressure of the rollers 9 to the fists 8 and the return of the matrix to its original upper position.

A hydraulic vibrator is built into the vibration table 14, consisting of a power cylinder 15 and a hydraulic pulse exciter 16 with a spring 17, which is controlled remotely (software) by a controlled servo mechanism 18 to change the vibration parameters of the hydraulic vibrator. The cyclic accumulator 19 and the hydraulic unit of a typical pump station 20 of a hydraulic vibrator are installed in the immediate vicinity.

The hydraulic exciter 16 of the vibratory pulses shown in FIG. 2 in the initial position contains a piston valve 21 with a return spring 24 and a brake plunger 25, a ball servo valve 22, a pressure plunger 23, an adjustable spring 17, a servo mechanism 18, a typical cyclic accumulator 19, the maximum amount of liquid in which is sufficient to provide one of the maximum possible vibration pulses of the hydraulic vibrator. A fairly complex system for switching hydrochannels between the main elements of the hydraulic exciter 16 is also shown in detail in FIG. 2.

The hydraulic exciter of vibratory pulses works as follows.

In the initial position, the spring 17, the force of which is set according to the program of the servo drive 18, acts on the pressure plunger 23, while the ball servo valve 22 is closed. The cavities above the piston valve 21 are connected by a channel P to the cyclic accumulator 19, which is unloaded in the initial state.

When you turn on the pumping station 20, the working fluid under the set pressure enters the cyclic accumulator 19, creating in it the volume necessary for one vibration pulse. The pressure in the accumulator 19 and in the cavity above the piston valve 21 and before the ball servo valve 22 rises to the set maximum value, counteracting the spring 17 through the pressure plunger 23.

When the force of the fluid pressure on the ball servo valve 22, exceeding the force of the spring 17, tightened using the servomechanism 18, the ball servo valve 22 opens and connects the cavity in front of the ball valve 22 and above the piston valve 21 with a drain line in the tank of the pump station 20.

The fluid pressure in the cyclic accumulator 19 rises when the fluid is pumped from the pump 20. The piston valve 21 moves upward due to the unbalanced force of the fluid pressure at the lower end of the piston of the valve 21. In the final upper position, the piston of the valve 21 stops unstressed using the brake plunger 25. The line is connected P with channel C and the cyclic accumulator 19 is completely discharged to the hydraulic cylinder 15, creating a pulsed effect on the vibrating table 14 with the matrix 11 installed on it on the pallet 13, filled Static preparation mixture.

At the next moment, as soon as the pressure of the working fluid in the cyclic accumulator 19 and the cavities of the hydraulic exciter 16 drops to the set minimum value under the action of the return spring 24, the piston of the valve 21 returns to the initial lower position described earlier, disconnecting the line P with the channel C. Thus, the piston valve 21 opens automatically at a certain high pressure of the liquid and closes at a certain low pressure. The hydraulic exciter cycle is repeated with programmable adjustable vibration parameters.

So, when the piston valve 21 is opened, liquid under pressure enters from the cyclic accumulator 19 into the power cylinder 15, and when the valve 21 is closed, the accumulator 19 is filled with liquid coming from the pump station 20 with the possibility of programmed control of the maximum flow and pressure of the pump station. This forms repetitively pulsed pressure pulses of the working fluid flowing into the actuator 15, which provides vibration exposure to the vibrating table 14 with a pallet 13 with the matrix 11 with the working mixture installed on it. The pressure is set remotely (programmatically) by a controlled servo mechanism 18 acting on the spring 17, a pressure plunger 23 and a ball servo valve 22 connected to the upper cavity of the piston valve 21.

Changing the frequency, amplitude of movements and the specific force of vibration is carried out by compression-weakening of the spring 17 due to the rotation of the adjusting screw using the actuating actuator 18 remote or programmed control, as well as, possibly, remote (programmed) control of pressure relief valve and pump station 20.

Embodiments of the servomechanism 18 may be, for example, the following:

1) a worm wheel is installed coaxially with the adjusting screw, which interacts with the worm shaft of the stepper motor. The control signal from the software device that is changed according to the program is fed to the input of a stepper motor, which, at the output, rotates the worm shaft and the worm wheel connected to it and the spring adjusting screw 17 connected to it by means of a spline connection. By turning the set angle, the adjustment screw increases or decreases the tightening force springs 17;

2) a hydraulic or pneumatic cylinder with a contactless rod-controlled remotely controlled program. The cylinder rod is connected to a rail interacting with a gear mounted coaxially with the adjusting screw;

3) a rotary hydraulic or pneumatic motor (but not a cylinder) with remote control mounted coaxially with the adjusting screw of the spring 17 and interacting with it by means of a spline connection.

Vibrating press works as follows. In the initial state, the matrix 11 and the slider 6 with punches are in the highest position. Fists 4 and 8 are turned to the zero position in accordance with the cycle. The pallet 13 is placed on the vibration table 14. The electric motor of the drive 2 of the vibrating press is on, the clutch is off, the brake is on. When the clutch is engaged, the brake is turned off, the main shaft 3 begins to rotate. The hydraulic vibrator operates during all three stages of the cycle of the proposed method of vibropressing. When the main shaft 3 rotates, the matrix 11 is lowered onto the pallet 13 under the influence of two fists 8, rollers 9 and rods 10. When the matrix 11 stops in the lower position, the working mixture is loaded into it. After that, the slider 6 with the punches fixed on it moves down towards the matrix 11. The slider 6 stops in its lowest position, providing a pause due to the profile of the fist 4. The matrix 11 moves upward under the action of the balancing air cylinders 12. Following the matrix 11 with a lag sufficient to stop the contact of the walls of the matrix 11 with the molded products, slider 6 moves upward with fixed punches under the influence of a fist 4 and roller 5. Matrix 11 and slider 6 with punches reach the extreme upper similar position under the action of the cylinder-uravnoveshivateley 7. The molded articles on the pallet 13 is moved to the receiving table or conveyor (not shown) for solidification. The vibrocompression cycle is complete.

The implementation of the proposed method of vibrocompression is illustrated by the generalized graphs in figure 3 and 4. Three stages of the process of effective vibrocompression: 1) filling the mixture with a high frequency (80 ... 100% of the maximum) and small amplitudes of vibration displacement and specific force of vibration (20 ... 50% of the maximum ); 2) preliminary vibration compaction with an average frequency (50 ... 80% of the maximum) and average amplitudes (50 ... 70% of the maximum); 3) final compaction with a low frequency (10 ... 50% of the maximum) and large amplitudes (70 ... 100% of the maximum).

The generalized dependences of the amplitude of vibration displacements (A, mm), frequency (v, Hz), and the amplitude of the specific (over area) force (q, kPa) of vibration compression on pressure (P, MPa) at the inlet of hydraulic exciter 16 are shown with fixed parameters of maximum flow and pressure pump station 20 at the stages of the vibrocompression cycle of cement-sand mixtures and other architectural and construction materials. By adjusting the pressure at the inlet of the vibration exciter 16 according to the program, the vibration compression modes are changed according to the stages of the process cycle. The most rational modes are established empirically for each material and item of the item, stored by the processor of the control computer system and repeated for the entire batch of products.

An example implementation of the method.

The case of vibrocompression of a product from semi-dry cement-sand mixtures was experimentally investigated. Ranges of regulation of vibration parameters, their changes according to the stages of the cycle: the vibration frequency was regulated in the range from 10 to 100 Hz, the specific vibration force in the range of 10 ... 200 kPa (pressure at the inlet of the hydraulic exciter from 1 to 20 MPa) with an amplitude of vibration displacement of 1 ... 3 mm .

Specifically, according to the stages of the cycle, the sets of adjustable parameters were as follows:

at stage 1: vibration frequency 100 Hz; vibration amplitude 1.0 mm; the amplitude of the specific force of vibration up to 100 kPa (50%); stage duration from 2 to 3 s;

at stage 2: vibration frequency 65 Hz; vibration amplitude 1.8 mm; the amplitude of the specific force of vibration up to 140 kPa (70%); stage duration from 0.5 to 1 s;

at stage 3: vibration frequency 10 Hz; vibration amplitude 3.0 mm; the amplitude of the specific force of vibration up to 200 kPa (100%); the duration of the stage is from 0.5 to 1 s.

The use of vibrocompression with these parameters provides the required level of specific forces and high efficiency of vibrocompression. In this case, the increase in the efficiency of vibration pressing is confirmed by objective numerical estimates of the results of experimental studies of the proposed method using the proposed device: an analysis of the technological features of the manufacturing process of semi-dry cement-sand mixtures, as well as mixtures based on nitride-silicon powders, has shown the promise of manufacturing complex vibration-pressed billets with three-stage cyclic vibrational loading of the mixture in the matrix, which allows you to achieve a workpiece density of 60% (this is about 25% better than traditional results) with an equal density of 95 ... 98%, almost unattainable with traditional methods of vibrocompression with unbalanced vibrators.
