Description

TECHNICAL FIELD

[0002] The flat gate valve is a sliding valve with a parallel gate as a closing part. The closing part can be a single gate or a double gate with a supporting mechanism between the two gates. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat.

[0003] The patent file with the publication number CN212578107U discloses a numerical control gate valve processing machine tool, which comprises a machine base, a mold clamping device is fixed in the middle of the machine base, and inclined cutting devices are arranged on both sides of the mold clamping device and are slidably connected between each cutting device and the machine base. The cutting device comprises a sliding seat, a main shaft sleeve is fixed on the sliding seat, a main shaft is sleeved in the main shaft sleeve, one end of the main shaft is connected with a sliding seat, and a pulley is fixed to the other end of the main shaft.

[0055] The driving unit 12 (such as Figure 5 As shown, the driving unit 12 is fixedly installed on the mounting base 1, and the two cutting tool heads 13 are fixedly installed on the driving unit 12, and the two cutting tool heads 13 are located on both sides below the gate body 5.

[0056] The bottom of the mounting base 1 is fixedly connected with the liquid storage tank 14, the liquid storage tank 14 is communicated with the communication groove 6, the second liquid inlet pipe 15 is arranged on both sides of the gate body 5, and the liquid delivery assembly is arranged on the liquid storage tank 14, and the cooling liquid in the liquid storage tank 14 is delivered to the corresponding first liquid inlet pipe 11 and the second liquid inlet pipe 15 through the action of the liquid delivery assembly.

[0057] The staff puts the gate body 5 into the protective shell 2 along the loading and unloading groove 3, and positions the gate body 5 below the movable plate 4 through the clamping assembly, drives the movable plate 4 to move vertically downward through the action of the lifting assembly, drives the two cutting tool heads 13 to rotate at high speed through the driving unit 12, and moves the gate body 5 downward between the two cutting tool heads 13, and cuts the two sides of the gate body 5 through the two cutting tool heads 13 respectively, so as to accurately cut the sealing surface on both sides of the gate body 5.

[0058] During the movement and cutting of the gate body 5, the liquid delivery assembly delivers the cooling liquid in the liquid storage tank 14 to the second liquid inlet pipe 15, and delivers the cooling liquid to the cutting position of the cutting tool head 13 and the gate body 5 along the adjacent end of the second liquid inlet pipe 15, so as to reduce the temperature of the cutting position and reduce the wear degree of the cutting tool head 13, prolong the service life of the cutting tool head 13, and flush the cutting debris generated at the cutting position by the continuous flow of the cooling liquid, prevent the cutting debris from adhering to the two sides of the gate body 5, and cool and flush the cutting position by the cooling liquid, so that the cooling liquid can be recycled.

[0059] The two sides of the gate body 5 are moved to between the two pressing rings 9 after being cut by the cutting tool head 13, the two sliding blocks 7 are driven to approach each other by the approaching assembly, the two pressing rings 9 are in contact with the two sides of the gate body 5 respectively, the cooling liquid in the liquid storage tank 14 is transported to the inside of the two first liquid inlet pipes 11 by the liquid delivery assembly, the cooling liquid enters the corresponding communication hole 8 along the inside of the first liquid inlet pipe 11, and is transported to the corresponding pressing ring 9, one end of the pressing ring 9 is in contact with the corresponding side of the gate body 5, when the thickness of the gate body 5 after cutting and the flatness of the two sides meet the processing precision requirements, the cooling liquid cannot flow out along one end of the pressing ring 9, the hydraulic sensor 10 monitors the hydraulic pressure in the pressing ring 9, when the monitoring value meets the pressure value calibrated in the sealed state, it is proved that the cutting processing of the gate body 5 meets the required precision, and the sealing effect of the gate body 5 in the actual use process is ensured, when the cutting position of the gate body 5 does not meet the processing precision, the cooling liquid seeps out along the contact position of the pressing ring 9 and the gate body 5 under the action of hydraulic pressure, at this time, the hydraulic monitoring value of the hydraulic sensor 10 cannot reach the calibrated pressure value, so that it is monitored that the cutting surface of the gate body 5 does not meet the processing precision, and the excessively worn cutting tool head 13 needs to be replaced;

[0060] The application discriminates whether the cutting precision of the two sides of the gate body 5 meets the requirements and whether the cutting tool head 13 needs to be replaced by the contact and pressing of the pressing ring 9 and the cutting surface of the gate body 5 and the monitoring of the hydraulic pressure in the pressing ring 9 by the hydraulic sensor 10, so that the cutting tool head 13 is fully utilized, and the equipment cost is reduced under the premise of ensuring the processing precision.

[0061] As a further embodiment of the application, the mounting base 1 is fixedly connected with two mounting frames 44, and the two mounting frames 44 are rotatably connected with two limiting rollers 45, and the two limiting rollers 45 are located above the two cutting tool heads 13 respectively;

[0062] The two sides of the communication groove 6 are both provided with lifting grooves 46, the lifting grooves 46 are both slidably connected with rectangular frames 47, the rectangular frames 47 are provided with sliding pins 48, one end of the sliding pin 48 penetrates through the rectangular frame 47 and extends into the communication groove 6 and is fixedly connected with a side bracket 49, the first circular pin 50 is fixedly inserted on the sliding pin 48, and the two sides of the lifting groove 46 are both provided with guide grooves 51, the guide grooves 51 comprise inclined sections 5101 and vertical sections 5102, and the two ends of the first circular pin 50 are located in the corresponding inclined sections 5101 respectively;

[0063] The two connecting rods 52 are fixedly connected to the movable plate 4, the bottom ends of the connecting rods 52 are slidably connected in the corresponding rectangular frames 47, first positioning holes 53 are formed in the connecting rods 52, the first positioning holes 53 are located above the corresponding rectangular frames 47, hydraulic cylinders 54 are fixedly installed on the rectangular frames 47, the piston shafts of the hydraulic cylinders 54 penetrate through the rectangular frames 47 and are fixedly connected with L-shaped plates 55 after extending into the rectangular frames 47, first positioning pins 56 are fixedly connected to the L-shaped plates 55, the connecting rods 52 are located between the corresponding sliding pins 48 and the first positioning pins 56, second positioning holes 57 are formed in the two sides of the lifting grooves 46, sliding grooves 58 are formed in the two sides of the rectangular frames 47, movable rods 59 are slidably connected in the sliding grooves 58, second positioning pins 60 are fixedly connected to one end of the movable rods 59, the second positioning pins 60 are located in the corresponding second positioning holes 57, second circular pins 61 are fixedly connected to the other end of the movable rods 59, two contraction grooves 62 are formed in the L-shaped plates 55, one end of the second circular pins 61 is located at one end in the corresponding contraction grooves 62;

[0064] Before the movable plate 4 drives the gate body 5 to move vertically downward and cut the two sides through the cutting tool head 13, the gate body 5 moves downward from between the two limiting rollers 45, and the limiting rollers 45 contact and roll on the side of the gate body 5 to limit the gate body 5, thereby improving the stability of the gate body 5 during cutting and reducing the thin-wall resonance caused by cutting force;

[0065] When the movable plate 4 moves downward, the connecting rods 52 move downward synchronously, so that the bottom ends of the connecting rods 52 slide downward in the rectangular frames 47, when the first positioning holes 53 on the connecting rods 52 are located at one end of the first positioning pins 56 during movement, the cutting part of the gate body 5 is located between the two side brackets 49, the L-shaped plates 55 are driven to move by the piston shafts of the hydraulic cylinders 54, so that the first positioning pins 56 fixedly connected to the L-shaped plates 55 move into the first positioning holes 53, thereby limiting the connecting rods 52 and the rectangular frames 47, when the L-shaped plates 55 move, the contraction grooves 62 limit and guide the second circular pins 61, so that the movable rods 59 move along the sliding grooves 58, and the second positioning pins 60 move synchronously, so that the second positioning pins 60 are separated from the second positioning holes 57, thereby limiting the connecting rods 52 and the rectangular frames 47 at the same time, and the limiting of the lifting grooves 46 to the rectangular frames 47 is released, so that the rectangular frames 47 can move downward synchronously with the connecting rods 52;

[0066] When the rectangular frame 47 moves downward, the sliding pin 48 and the side bracket 49 move downward synchronously, the first circular pin 50 on the sliding pin 48 moves inside the guide slot 51, and the sliding pin 48 moves along the sliding through hole of the rectangular frame 47 through the limiting guide of the inclined section 5101, and the side bracket 49 moves to the corresponding side of the shutter body 5, when the first circular pin 50 moves from the inclined section 5101 to the vertical section 5102, the side bracket 49 contacts and limits the side of the shutter body 5, when the first circular pin 50 moves downward in the vertical section 5102, the side bracket 49 keeps contacting and moving downward synchronously with the side of the shutter body 5, so that the side bracket 49 limits the cut part of the shutter body 5, and the side bracket 49 follows the shutter body 5 to keep the limiting support point unchanged during movement, so as to improve the stability of the limiting support and reduce the contact friction of the shutter body 5 during limiting.

[0067] As a further embodiment of the application, the infusion assembly comprises:

[0068] Two liquid pumps 16 (as shown in Figure 3 The two liquid pumps 16 are fixedly installed on the two sides of the installation base 1, the liquid inlet end of the liquid pump 16 is fixedly connected to the liquid storage tank 14, the fixed connection part of the liquid pump 16 and the liquid storage tank 14 is fixedly installed with a filter 21, the liquid outlet end of the liquid pump 16 is fixedly connected with an electric control switching valve 17, the first liquid inlet pipe 11 is fixedly inserted into the installation base 1, the second liquid inlet pipe 15 is fixedly inserted into the protective shell 2, and the electric control switching valve 17 is fixedly connected with the corresponding first liquid inlet pipe 11 and second liquid inlet pipe 15.

[0069] When the liquid pump 16 works, the cooling liquid in the liquid storage tank 14 is pumped into the liquid pump 16, and then pumped to the electric control switching valve 17 along the liquid outlet end of the liquid pump 16, the valve path of the electric control switching valve 17 controls to close the first liquid inlet pipe 11 and open the second liquid inlet pipe 15, so that the cooling liquid enters the second liquid inlet pipe 15 and is discharged from one end of the second liquid inlet pipe 15, thereby cooling and flushing the cutting position with the cooling liquid, when the two sliding blocks 7 contact the shutter body 5 through the approaching assembly, the electric control switching valve 17 opens the first liquid inlet pipe 11 and closes the second liquid inlet pipe 15, so that the cooling liquid enters the first liquid inlet pipe 11, thereby monitoring the contact sealing property of the pressing ring 9 and the shutter body 5.

[0070] When the cooling liquid cools and flushes the cutting position, the cutting debris enters the liquid storage tank 14 with the cooling liquid, and the filter 21 filters and collects the cutting debris carried in the cooling liquid, thereby improving the circulation frequency and use time of the cooling liquid, and reducing the influence of the cutting debris on the circulation use of the cooling liquid.

[0071] As a further embodiment of the present invention, such as Figure 8 As shown, a liquid level sensor 18 is fixedly installed on the top of the pressure ring 9, and the sensing end of the liquid level sensor 18 extends into the interior of the pressure ring 9. An exhaust pipe 19 is fixedly connected to the top of the pressure ring 9, and an electrically controlled shut-off valve 20 is fixedly installed on the exhaust pipe 19.

[0072] After the two pressure rings 9 contact the two sides of the gate body 5 respectively, the coolant enters the corresponding connecting hole 8 through the first inlet pipe 11 and moves into the pressure ring 9. As the coolant enters, the air in the first inlet pipe 11, the connecting hole 8 and the pressure ring 9 is discharged through the exhaust pipe 19. At the same time, the liquid level sensor 18 continuously monitors the coolant level inside the pressure ring 9. When the gas inside the pressure ring 9 is completely discharged and filled with coolant, the monitoring value of the liquid level sensor 18 reaches the calibration value. The controller connected to the liquid level sensor 18 controls the electric shut-off valve 20 to close. At the same time, the hydraulic sensor 10 starts to work and monitors the hydraulic value inside the pressure ring 9. When the hydraulic value inside the pressure ring 9 meets the pressure value calibrated under the sealed state, the cutting on both sides of the gate body 5 meets the machining accuracy.

[0073] By cooperating with the liquid level sensor 18 and the electronically controlled shut-off valve 20, all the air inside the pressure ring 9 is discharged to form a closed hydraulic space, thereby reducing the impact of residual air on hydraulic value monitoring. Furthermore, hydraulic value monitoring is performed after the pressure ring 9 is completely filled with coolant, which can prevent changes in hydraulic value caused by the gradual increase of liquid and improve the accuracy of hydraulic value.

[0074] As a further embodiment of the present invention, each of the two second liquid inlet pipes 15 is fixedly connected to a sealing housing 22 at one adjacent end, and each of the two sealing housings 22 is fixedly connected to a plurality of guide pipes 23 on one adjacent side, and each of the guide pipes 23 is fixedly installed with a straight nozzle 24 at one end.

[0075] The coolant enters the sealed housing 22 through the second inlet pipe 15 and then enters the corresponding guide pipe 23 through the sealed housing 22. The guide pipe 23 guides the flow of the coolant so that it can act on the contact position between the cutting head 13 and the gate body 5. The lateral range of the coolant is increased by the straight nozzle 24 to ensure that the coolant can fully cool and clean the cutting position.

[0076] As a further embodiment of the present invention, the lifting assembly includes:

[0077] Multiple limit pins 25 are fixedly connected to the top of the movable plate 4, and the limit pins 25 are slidably inserted into the protective shell 2.

[0078] The first electric cylinder 26 is fixedly installed on the top of the protective housing 2. The drive shaft of the first electric cylinder 26 passes through the protective housing 2 and extends into the interior of the protective housing 2 before being fixedly connected to the top of the movable plate 4.

[0079] The transmission shaft of the first electric cylinder 26 moves downward, causing the movable plate 4 to move downward synchronously, which in turn causes the gate body 5 to move downward. Multiple limit pins 25 move along the sliding joint, thereby limiting the movement of the movable plate 4. When the transmission shaft of the first electric cylinder 26 moves upward, the movable plate 4 causes the gate body 5 to move upward and return to the initial position.

[0080] As a further embodiment of the present invention, the approaching component includes:

[0081] Two U-shaped frames 27 are fixedly connected to both ends of the bottom of the movable plate 4. Each U-shaped frame 27 has two inclined slots 28.

[0082] Two mounting brackets 29 are fixedly connected to two sliders 7 respectively. Two rotating pins 30 are rotatably connected to each mounting bracket 29. The two rotating pins 30 are located inside the corresponding inclined grooves 28.

[0083] When the drive shaft of the first electric cylinder 26 drives the movable plate 4 to move downward, it drives the two U-shaped frames 27 to move downward synchronously. Through the limiting and guiding effect of the inclined groove 28 on the rotating pin 30, the two mounting brackets 29 are brought closer to each other. Through the fixed connection between the mounting brackets 29 and the slider 7, the two sliders 7 are brought closer to each other along the sliding connection of the connecting groove 6. When the drive shaft of the first electric cylinder 26 reaches the maximum moving distance, the two sliders 7 drive the corresponding pressure rings 9 to move closer to each other and reach the closest distance, so that the two pressure rings 9 contact the two sides of the gate body 5 respectively. When the gate body 5 moves downward, the two pressure rings 9 move closer to each other and finally contact the side of the gate body 5, thereby reducing the sliding friction generated between the gate body 5 and the pressure rings 9 when moving, and reducing the impact of the wear of the pressure rings 9 on the seal.
