Description
Technical Field
[0001] This invention relates to the field of block pressing and molding equipment, and more specifically, to a hydraulic automatic block molding machine. Background Technology
[0002] Hydraulic block forming machines are brick-making equipment used to produce hollow blocks, paving bricks and other new building materials from industrial waste (such as coal gangue, fly ash, slag, etc.). They are environmentally friendly block forming equipment.
[0003] During long-term reciprocating operation of a hydraulic block molding machine, the hydraulic oil in the hydraulic cylinder is prone to excessively high pressure, leading to excessively high oil temperature. When the oil temperature rises, the piston in the hydraulic cylinder is prone to thermal expansion, causing the fit between the piston and the inner wall of the hydraulic cylinder to become too tight. This undoubtedly increases the resistance during piston movement and increases the friction between the piston and the cylinder wall, which in turn accelerates the wear of the hydraulic cylinder wall. Furthermore, when the inner wall of the hydraulic cylinder wears down, the clearance between the piston and the cylinder wall increases, and high-pressure oil leaks through the clearance into the low-pressure chamber, causing unstable pressure in the hydraulic system of the hydraulic block molding machine. The piston movement speed fluctuates, exhibiting a "creeping" phenomenon, which reduces the output force of the hydraulic block molding machine, making it unable to meet the pressing requirements of the block raw materials and affecting the pressing and molding effect of the block products.
[0004] In view of this, we propose a hydraulic automatic block forming machine. Summary of the Invention

[0028] The hydraulic cylinder is fixedly connected to the main frame, and the free end of the hydraulic cylinder is connected to the lifting base located below it.
[0029] As an optional solution to the technical solution of this invention document, an oil injection pipe connected to the cooling cavity is also connected to the side wall of the hydraulic cylinder.
[0030] The oil injection pipe is equipped with a one-way inlet valve.
[0031] Beneficial Effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. During the operation of the hydraulic block molding machine, the pressure sensing unit installed in the filling port of the hydraulic cylinder can monitor the wear degree of the inner wall of the hydraulic cylinder in real time, and can send an alarm signal when the wear degree reaches the preset upper limit, reminding the staff to repair or replace it in time. This can effectively avoid the situation where the hydraulic block molding machine cannot meet the pressing requirements of the block raw materials due to unstable hydraulic pressure during the pressing process, thus ensuring the molding effect of the block products.
[0032] 2. Real-time monitoring of the wear degree of the upper trough plate during material crushing is achieved through the coordinated operation of the liquid cooling medium in the cooling cavity and the pressure sensing unit located in the filling port. When the wear depth of the inner wall of the hydraulic cylinder reaches the preset critical upper limit, the liquid cooling medium leaks out from 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. 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, controlling the second alarm to open. The opened second alarm then sends an alarm signal to remind the staff to repair or replace the hydraulic cylinder in a timely manner.
[0033] 3. During the pressing of block raw materials by the hydraulic cylinder in the hydraulic block molding machine, the liquid cooling medium in the cooling cavity can continuously absorb the heat energy from the hydraulic oil inside the hydraulic cylinder. The heat energy absorbed by the liquid cooling medium can also be continuously conducted to the surrounding environment through the outer wall of the hydraulic cylinder, thereby cooling the hydraulic oil and maintaining the temperature stability of the hydraulic oil during the pressing and molding process of the block raw materials. This helps to reduce the situation where the piston in the hydraulic cylinder expands due to overheating of the hydraulic oil, causing the fit between it and the inner wall of the hydraulic cylinder to become too tight, which would lead to wear of the inner wall of the hydraulic cylinder.
[0034] 4. First, install the pressure sensing unit inside the filling port. Then, the operator conveniently injects liquid cooling medium into the cooling cavity through the hydraulic cylinder. As the liquid cooling medium fills the cooling cavity, the hydraulic pressure continuously compresses the elastic synchronous air bladder, causing the elastic air bladder component to continuously inject gas into the inner cavity of the hollow sealing ring in the piston component through the guide channel. The thin-walled part that undergoes elastic expansion can tightly adhere to the inner wall of the filling port. This allows the hydraulic cylinder to better adapt to the slight deformation of the sealing surface of the filling port side wall during the pressing and molding of the block material and maintain tight contact with the sealing surface. This enhances the sealing adaptability of the pressure sensing unit, ensures the stability of the pressure sensing unit's seal, and prevents the accuracy of the wear monitoring results from being affected by leakage of the liquid cooling medium during the pressing and molding of the block material, thus ensuring monitoring accuracy.
[0035] 5. When the oil temperature inside the hydraulic cylinder overheats, causing the piston inside the cylinder to expand thermally, the inner wall of the hydraulic cylinder deforms. The deformed inner wall of the cylinder drives the cooling cavity to undergo synchronous compression deformation, which in turn increases the hydraulic pressure in the cooling cavity and further compresses the elastic air bladder component through the piston component. After the elastic synchronous air bladder in the elastic air bladder component is further compressed, it drives the insulating follower rod to retract into the guide bottom cylinder. When the deformation degree of the inner wall of the hydraulic cylinder reaches the preset critical upper limit, the free end of the insulating spring aligns with the first elastic diaphragm and drives the male trigger terminal A to contact the female trigger terminal A. The trigger control circuit board controls the wireless signal transmitter to send an opening control signal to the first alarm. The control signal enables the liquid cooling medium section and the pressure sensing unit located in the filling port to monitor the wear degree of the inner wall of the hydraulic cylinder. At the same time, it can further monitor the deformation degree of the inner wall of the hydraulic cylinder during the material pressing process. When the deformation degree of the inner wall of the hydraulic cylinder reaches the preset critical upper limit, it can promptly trigger the first alarm to open, reminding the staff to replace the severely deformed hydraulic cylinder in time. This avoids the situation where the clearance between the piston and the inner wall of the hydraulic cylinder increases, causing hydraulic oil to leak from the seal failure point, resulting in a drop in system pressure, which in turn affects the block forming effect. This ensures the pressing and forming effect of the block products. Attached Figure Description

[0052] Reference Figures 1 to 10 The present invention provides a hydraulic automatic block forming machine, including a frame body 101, an upper mold assembly in the inner cavity of the frame body 101, and a hydraulic drive component for driving the upper mold assembly to move up and down on the frame structure.
[0053] The hydraulic drive component includes a hydraulic cylinder 203. A cooling cavity is provided in the inner ring of the cylinder side wall of the hydraulic cylinder 203. The cooling cavity is filled with a liquid cooling medium 209. A plugging port connected to the cooling cavity is opened on the side wall of the hydraulic cylinder 203. A pressure sensing unit is sealed in the plugging port. The liquid cooling medium 209 is hydraulic oil.
[0054] The pressure sensing unit includes an alarm component, a piston component, and a T-shaped column 205 that is detachably connected to the filling port, wherein the detachable connection method includes threaded connection or snap-fit connection.
[0055] The piston assembly includes a piston seat 212. A hollow sealing ring 215 with an inner cavity filled with gas is sleeved around the outer periphery of the side wall of the piston seat 212. The piston seat 212 slides in the filling port through the sealing ring 215. The outer ring wall of the hollow sealing ring 215 is a thin-walled part 216. An elastic air bladder assembly that communicates with the hollow sealing ring 215 in the piston assembly is provided between the T-shaped column 205 and the piston assembly.
[0056] Reference Figure 1 and Figure 5 This invention provides a hydraulic automatic block forming machine, wherein the upper mold assembly includes a lifting base 102 and an upper template 103 is connected to the bottom of the lifting base 102;
[0057] The hydraulic cylinder 203 is fixedly connected to the frame body 101, and the free end of the hydraulic cylinder 203 is connected to the lifting base 102 located below it.
[0058] During the operation of the hydraulic block molding machine, the pressure sensing unit installed in the filling port of the hydraulic cylinder 203 can monitor the wear degree of the inner cavity side wall of the hydraulic cylinder 203 in real time. When the wear degree reaches the preset upper limit, it can send an alarm signal to remind the staff to repair or replace it in time. This can effectively prevent the hydraulic block molding machine from reducing its output force due to unstable hydraulic pressure during the pressing of raw materials, thus failing to meet the pressing requirements of the block raw materials and ensuring the molding effect of the block products.
[0059] Reference Figures 3 to 6 The present invention provides a hydraulic automatic block forming machine, wherein the elastic airbag component includes a guide channel 213 and an elastic synchronous airbag 211;
[0060] The end of the elastic synchronized airbag 211 is connected to a rotating seat, and the end of the elastic synchronized airbag 211 away from the rotating seat is connected to the piston seat 212. The rotating seat is rotatably connected to the T-shaped column 205.
[0061] The elastic synchronous airbag 211 has a guide bottom cylinder 217 inside, and an insulated following rod is slidably inserted into the end of the guide bottom cylinder 217.
[0062] An insulating spring piece 219 is connected to the inner wall of the guide bottom cylinder 217 to work in conjunction with the insulating follower rod;
[0063] The guide channel 213 is located inside the piston seat 212, and the elastic synchronous airbag 211 and the hollow sealing ring 215 are interconnected through the guide channel 213.
[0064] Reference Figures 7 to 10 The present invention provides a hydraulic automatic block forming machine, wherein the insulating follower rod includes an insulating advance and retreat rod 214 that is sealed and slidably inserted at the end of the guide bottom cylinder 217;
[0065] An insulated advance / retreat rod 214 has a preset opening on its side wall that is opposite to the insulated spring 219. An insulated cover 218 is detachably connected inside the preset opening. A control circuit board 226 is connected inside the cavity of the insulated cover 218. A wireless signal transmitter 227 is connected to the control circuit board 226.
[0066] The insulating cover 218 has a right opening and a left opening on its side wall, respectively;
[0067] A first elastic diaphragm 220 is connected to the right opening, and a second elastic diaphragm 221 is connected to the left opening;
[0068] A male trigger terminal A222 is connected to the first elastic diaphragm 220, and a male trigger terminal B224 is connected to the second elastic diaphragm 221. Both the male trigger terminal A222 and the male trigger terminal B224 are electrically connected to the control circuit board 226.
[0069] On the control circuit board 226, female trigger terminals A223 and B225 are respectively connected at positions corresponding to male trigger terminals A222 and B224;
[0070] The side wall surface of the insulating cover 218 is flush with the side wall surface of the insulating advance / retreat rod 214;
[0071] The opposite ends of the insulating advance and retreat rod 214 and the guide bottom cylinder 217 are both connected to the inner wall of the elastic synchronous airbag 211;
[0072] The free end of the insulating spring 219 is in close contact with the side wall surface of the insulating cover 218.
[0073] Reference Figures 7 to 10 This invention provides a hydraulic automatic block forming machine. The alarm component includes a first alarm 207 and a second alarm 208 connected to the side wall of a T-shaped column 205. Both the first alarm 207 and the second alarm 208 are preferably audible and visual alarms. The sound and light signals emitted by the first alarm 207 and the second alarm 208 are different when they are running. For example, the first alarm 207 flashes yellow light when it is running, and the second alarm 208 flashes red light when it is running. Both the first alarm 207 and the second alarm 208 are pre-installed with signal receivers that can receive control commands from a wireless signal transmitter.
[0074] When the male trigger terminal A222 contacts the female trigger terminal A223, the trigger control circuit board 226 controls the wireless signal transmitter 227 to send an activation control signal to the first alarm 207.
[0075] When the male trigger terminal B224 contacts the female trigger terminal B225, the trigger control circuit board 226 controls the wireless signal transmitter 227 to send an activation control signal to the second alarm 208.
[0076] The wear of the upper trough plate is monitored in real time during material crushing through the coordinated operation of the liquid cooling medium 209 in the cooling cavity and the pressure sensing unit located in the filling port. When the wear depth of the inner wall of the hydraulic cylinder 203 reaches the preset critical upper limit, the liquid cooling medium 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. After the free end of the insulating spring 219 aligns with the second elastic diaphragm 221, the insulating spring 219 drives the male trigger terminal B224 to contact the female trigger terminal B225 and triggers the control circuit board 226 to control the wireless signal transmitter 227 to send an opening control signal to the second alarm 208, controlling the second alarm 208 to open. The opened second alarm 208 then sends an alarm signal to remind the staff to repair or replace the hydraulic cylinder 203 in a timely manner.
[0077] During the process of pressing the block material by the hydraulic cylinder 203, the liquid cooling medium 209 located in the cooling cavity can continuously absorb the heat energy from the hydraulic oil inside the cylinder of the hydraulic cylinder 203. The heat energy absorbed by the liquid cooling medium 209 can also be continuously conducted to the surrounding environment through the outer wall of the cylinder of the hydraulic cylinder 203, thereby cooling the hydraulic oil and maintaining the temperature stability of the hydraulic oil during the pressing and molding process of the block material. This helps to reduce the situation where the piston in the hydraulic cylinder 203 expands due to overheating of the hydraulic oil, causing the fit between it and the inner wall of the cylinder of the hydraulic cylinder 203 to be too tight, which would lead to wear of the inner wall of the cylinder of the hydraulic cylinder 203.
[0078] When the oil temperature inside the hydraulic cylinder 203 overheats, causing the piston inside the cylinder to expand thermally, the inner wall of the hydraulic cylinder 203 deforms. The deformed inner wall of the cylinder drives the cooling cavity to undergo synchronous compression deformation, thereby increasing the hydraulic pressure inside the cooling cavity and further compressing the elastic airbag component through the piston component. After the elastic synchronous airbag 211 in the elastic airbag component is further compressed, it drives the insulating follower rod to retract into the guide bottom cylinder 217. When the deformation degree of the inner wall of the hydraulic cylinder 203 reaches the preset critical upper limit, the free end of the insulating spring 219 aligns with the first elastic diaphragm 220 and drives the male trigger terminal A222 to contact the female trigger terminal A223. The trigger control circuit board 226 controls the wireless signal transmitter 227 to send a signal to the first alarm 207. The system sends an activation control signal, enabling the liquid cooling medium section 209 to work with the pressure sensing unit located in the filling port to monitor the wear degree of the inner wall of the cylinder 203. Simultaneously, it can further monitor the deformation degree of the inner wall of the cylinder 203 during material pressing in real time. When the deformation degree of the inner wall of the cylinder 203 reaches a preset critical upper limit, it can promptly trigger the first alarm 207 to remind personnel to replace the severely deformed hydraulic cylinder 203. This prevents the hydraulic oil from leaking from the seal failure point due to increased clearance between the piston and the inner wall of the cylinder 203, which could lead to a drop in system pressure and affect the block forming effect, thus ensuring the pressing and forming effect of the block products.
[0079] Reference Figure 1 and Figure 2 The present invention provides a hydraulic automatic block forming machine, wherein the hydraulic cylinder 203 is also connected to an oil injection pipe 201 that communicates with the cooling cavity on its side wall;
[0080] The oil injection pipe 201 is equipped with a one-way inlet valve.
[0081] First, the pressure sensing unit is installed inside the filling port. Then, the operator conveniently injects liquid cooling medium 209 into the cooling cavity through hydraulic cylinder 203. As the liquid cooling medium 209 fills the cooling cavity, the hydraulic pressure continuously compresses the elastic synchronous airbag 211 through 212. This causes the elastic airbag component to continuously inject gas into the inner cavity of the hollow sealing ring 215 in the piston component through the guide channel 213. The thin-walled part 216, which expands elastically, can fit tightly against the inner wall of the filling port. This allows the hydraulic cylinder 203 to better adapt to the slight deformation of the sealing surface of the filling port side wall and maintain tight contact with the sealing surface during the pressing and molding of the block material. This enhances the sealing adaptability of the pressure sensing unit, ensures the stability of the pressure sensing unit's seal, and prevents the accuracy of the wear monitoring results from being affected by leakage of the liquid cooling medium during the pressing and molding of the block material, thus ensuring monitoring accuracy.
