Description

Technical Field

[0001] The present invention relates to the technical field of block pressing and forming equipment, and more particularly to a hydraulic automatic block forming machine. Background Art

[0002] The hydraulic block forming machine is a brick making machine used to produce hollow blocks, pavement bricks and other new building materials using industrial waste (such as coal gangue, fly ash, slag, etc.) as raw materials. It is an environmentally friendly block forming equipment.

[0003] When the hydraulic block forming machine is in long-term reciprocating operation, the hydraulic oil in its hydraulic cylinder is prone to high pressure, resulting in excessively high oil temperature. When the oil temperature rises, the piston in the hydraulic cylinder is prone to thermal expansion, making the fit between the piston and the inner wall of the hydraulic cylinder too tight. This will undoubtedly increase the resistance of the piston during movement and increase the friction between the piston and the cylinder wall, which will accelerate the wear of the hydraulic cylinder wall. Moreover, when the inner wall of the hydraulic cylinder is worn, the fit gap between the piston and the cylinder wall increases, and the high-pressure oil leaks into the low-pressure chamber through the gap, resulting in unstable pressure of the hydraulic system in the hydraulic block forming machine, and the piston movement speed fluctuates, resulting in a "creeping" phenomenon, which causes the output force of the hydraulic block forming machine to decrease, and cannot meet the pressing requirements for the block raw materials, affecting the pressing and forming effect of the block products.

[0004] In view of this, we propose a hydraulic automatic block forming machine. Summary of the Invention

A control circuit board is connected to the inner cavity of the insulating cover, and a wireless signal transmitter is connected to the control circuit board. The side walls of the insulating cover are respectively provided with a right opening and a left opening; The right opening is connected to a first elastic diaphragm, and the left opening is connected to a second elastic diaphragm; The first elastic diaphragm is connected to a male trigger terminal A, the second elastic diaphragm is connected to a male trigger terminal B, and both the male trigger terminal A and the male trigger terminal B are electrically connected to the control circuit board; The positions of the control circuit board corresponding to the male trigger terminal A and the male trigger terminal B are connected to the female trigger terminal A and the female trigger terminal B respectively.

[0015] As an optional solution of the technical solution of the present invention, the side wall of the hydraulic cylinder is further connected to an oil filling pipe communicating with the cooling cavity; A one-way liquid inlet valve is provided on the oil filling pipe.

[0016] Beneficial effects: One or more technical solutions provided in the technical solution of the present invention have at least the following technical effects or advantages: 1. During the operation of the hydraulic block forming machine, the pressure sensing unit installed in the filling port of the hydraulic cylinder can monitor the degree of wear of the side wall of the inner cavity of the hydraulic cylinder in real time, and when the degree of wear reaches a preset upper limit, an alarm signal can be sent out to remind the staff to repair or replace it in time, thereby effectively avoiding the situation in which the output force of the hydraulic block forming machine decreases due to unstable hydraulic pressure during the pressing of raw materials, and thus cannot meet the pressing requirements of the block raw materials, thereby ensuring the forming effect of the block products.

[0017] 2. Through the cooperation between the liquid cooling medium part in the cooling cavity and the pressure sensing unit located in the filling port, real-time monitoring of the wear degree of the upper groove plate is achieved during the material crushing process. When the wear depth of the side wall of the inner cavity of the hydraulic cylinder reaches the preset critical upper limit, the liquid cooling medium part leaks out of the cooling cavity, and the hydraulic pressure inside the cooling cavity gradually decreases. In this process, the elastic airbag component in the pressure sensing unit gradually changes from a compressed state to an initial relaxed state, driving the insulating following rod to gradually extend from the end of the guide bottom cylinder. After the free end of the insulating spring is aligned with the second elastic diaphragm, the insulating spring drives the male trigger terminal B to contact the female trigger terminal B and triggers the control circuit board to control the wireless signal transmitter to send an opening control signal to the second alarm, control the second alarm to turn on, and then the opened second alarm sends an alarm signal to the outside, reminding the staff to repair or replace the hydraulic cylinder in time.

[0018] 3. During the process of the hydraulic block forming machine pressing the block raw materials through the hydraulic cylinder, the liquid cooling medium part located in the cooling cavity can also continuously absorb the heat energy of the hydraulic oil inside the hydraulic cylinder barrel, and the heat energy absorbed by the liquid cooling medium part can also be continuously conducted to the surrounding environment through the outer wall of the hydraulic cylinder barrel, thereby realizing the cooling treatment of the hydraulic oil and maintaining the temperature stability of the hydraulic oil during the pressing and forming process of the block raw materials, thereby helping to reduce the thermal expansion of the piston in the hydraulic cylinder due to overheating of the hydraulic oil, causing the piston to fit too tightly with the inner wall of the hydraulic cylinder barrel, thereby causing wear on the inner wall of the hydraulic cylinder barrel.

[0019] 4. First install the pressure sensing unit inside the filling port, and then the staff injects the liquid cooling medium into the cooling cavity through the hydraulic cylinder. When the liquid cooling medium fills the cooling cavity, the hydraulic pressure continuously squeezes the elastic synchronous airbag, so that the elastic airbag component continuously injects gas into the inner cavity of the hollow sealing ring in the piston component through the guide channel. The elastically expanded thin-walled part can fit tightly against the inner wall of the filling port, so that the hydraulic cylinder can better adapt to the slight deformation of the sealing surface of the side wall of the filling port when it is impacted and vibrated during the pressing and molding of the block raw materials and can keep close to the sealing surface, thereby enhancing the sealing adaptability of the pressure sensing unit, ensuring the sealing stability of the pressure sensing unit, and preventing the block raw materials from leaking due to the liquid cooling medium during the pressing and molding process, which affects the accuracy of the wear degree monitoring results, thereby ensuring monitoring accuracy.

[0020] 5. When the oil temperature in the hydraulic cylinder barrel overheats and causes the piston in the cylinder barrel to thermally expand, causing the inner wall of the hydraulic cylinder barrel to deform, the deformed inner wall of the cylinder barrel drives the cooling cavity to undergo synchronous extrusion deformation, thereby increasing the hydraulic pressure in the cooling cavity and further squeezing the elastic airbag component through the piston component. After the elastic synchronous airbag in the elastic airbag component is further squeezed, the insulating follower rod is driven to retract into the inside of the guide bottom cylinder. When the deformation degree of the side wall of the hydraulic cylinder cavity reaches the preset critical upper limit, the free end of the insulating spring is aligned with the first elastic diaphragm and drives the male trigger terminal A to contact the female trigger terminal A, triggering the control circuit board to control the wireless signal transmitter to send an opening control signal to the first alarm. The control signal is generated so that the cooperation between the liquid cooling medium part and the pressure sensing unit located in the filling port can realize the monitoring of the wear degree of the inner wall of the cylinder barrel in the hydraulic cylinder. At the same time, it can further monitor the deformation degree of the inner wall of the hydraulic cylinder barrel during the material pressing process in real time, and can promptly trigger the control of the first alarm to open after the deformation degree of the inner wall of the hydraulic cylinder barrel reaches the preset critical upper limit, reminding the staff to replace the hydraulic cylinder with severe deformation in time, to avoid the increase of the matching clearance between the piston in the hydraulic cylinder barrel and the inner wall of the hydraulic cylinder barrel, and the leakage of hydraulic oil from the seal failure point, which leads to a drop in system pressure and affects the block forming effect, thereby ensuring the pressing and forming effect of the block products.

An insulating cover 218 is detachably connected to the preset opening. A control circuit board 226 is connected to the inner cavity of the insulating cover 218. A wireless signal transmitter 227 is connected to the control circuit board 226.

[0041] Reference Figures 7 to 10 , an embodiment of the present invention provides a hydraulic automatic block forming machine, wherein the alarm assembly includes a first alarm 207 and a second alarm 208 connected to the side wall of a T-shaped column 205, wherein the first alarm 207 and the second alarm 208 are preferably sound and light alarms, and the sound and light signals emitted by the first alarm 207 and the second alarm 208 are different when they are in operation.

[0042] The wear degree of the upper groove plate is monitored in real time during the material crushing process by the cooperation between the liquid cooling medium part 209 in the cooling cavity and the pressure sensing unit located in the filling port. When the wear depth of the side wall of the inner cavity of the hydraulic cylinder 203 reaches the preset critical upper limit, the liquid cooling medium part 209 leaks out of the cooling cavity, and the hydraulic pressure inside the cooling cavity gradually decreases. During this process, the elastic airbag component in the pressure sensing unit gradually changes from a compressed state to an initial relaxed state, driving the insulating follower rod to gradually extend from the end of the guide bottom cylinder.

[0043] In the process of pressing the block raw materials by the hydraulic cylinder 203, the liquid cooling medium part 209 located in the cooling cavity can continuously absorb the heat energy of the hydraulic oil from the inside of the cylinder barrel of the hydraulic cylinder 203, and the heat energy absorbed by the liquid cooling medium part 209 can be continuously conducted to the surrounding environment through the outer wall of the cylinder barrel of the hydraulic cylinder 203, realizing the cooling treatment of the hydraulic oil, maintaining the temperature stability of the hydraulic oil in the process of pressing and forming the block raw materials, thereby helping to reduce the situation that the piston in the hydraulic cylinder 203 is too tightly matched with the inner wall of the cylinder barrel of the hydraulic cylinder 203 due to thermal expansion of the piston caused by overheating of the hydraulic oil, and further causing the wear of the inner wall of the cylinder barrel of the hydraulic cylinder 203.

[0044] When the oil temperature in the cylinder barrel of the hydraulic cylinder 203 is overheated and causes the piston in the cylinder barrel to be thermally expanded, the inner wall of the cylinder barrel is deformed, the deformed cylinder barrel wall drives the cooling cavity to be synchronously extruded, and further causes the hydraulic pressure in the cooling cavity to increase and further extrude the elastic air bag part through the piston part.
