Description

Technical Field

[0001] The invention relates to a valve red flushing device. Background Art

[0002] Valve hot-stamping equipment is an automated equipment that can cut copper rods into certain lengths, heat them until they are red hot, and then extrude them into valve blanks. After the existing valve hot-stamping equipment makes the copper rods into valve blanks, the valve blanks cannot be discharged automatically and can only be taken out manually. Therefore, the labor intensity is high and the work efficiency is low. Moreover, the operators are in direct contact with the high-temperature valve blanks, which poses a safety hazard. In addition, the cooling effect of the movable mold and the fixed mold of the valve hot-stamping equipment is also poor, which makes it difficult to demold the valve blank. Once the demolding becomes stuck, the machine must be stopped and the valve blank must be manually removed, which leads to production interruption and urgently needs to be resolved.

[0028] The other end of the first discharge pipe 193 is connected to the interior of both the fixed mold 14 and the movable mold 15 .

[0029] A plurality of heat-insulating rods 1819 arranged in sequence laterally are fixed to the inner bottom of the receiving hopper 186 , and the left ends of the plurality of heat-insulating rods 1819 are all located on the right side of the discharge port 1861 .

[0030] A laterally distributed buffer 1818 is also embedded in the end block 189 , and the telescopic end of the buffer 1818 is laterally arranged to the right and cooperates with the left side of the first side block 187 .

[0031] A discharge hole 111 is provided on the left side of the cabinet 11, and an inclined discharge trough 1820 is fixed on the left outer wall of the cabinet 11. The higher end of the discharge trough 1820 passes through the discharge hole 111 and extends into the interior of the cabinet 11 and cooperates with the discharge port 1861.

[0032] A first atomizing nozzle 1823 and a second atomizing nozzle 1824 are fixed on the front and rear sides of the right end of the receiving hopper 186. The mist outlets of the two first atomizing nozzles 1823 pass through the front and rear sides of the receiving hopper 186 respectively and are both inclined upward toward the direction of the movable mold 15; the mist outlets of the two second atomizing nozzles 1824 are both inclined downward toward the direction of the fixed mold 14; the liquid inlets of the two first atomizing nozzles 1823 and the liquid inlets of the two second atomizing nozzles 1824 are all connected in parallel to the other end of the fourth discharge pipe 199.

[0033] Working principle: After molding, the high-temperature short material forms a valve blank, and the pressure mechanism 13 drives the movable mold 15 to move upward to leave the fixed mold 14. The valve blank is embedded in the movable mold 15 and moves upward at the same time as the movable mold 15; the upward movement of the movable mold 15 will pull the traction plate 185 to the right with the help of the connecting rod 182, so that it can move horizontally to the right along the guide rail 1810 with the help of several sliders 1811, and then drive the receiving hopper 186 to move to the right with the help of the support frame 1821 until the telescopic end of the buffer 1818 is pressed against the left side of the first side block 187. At this time, the right end of the receiving hopper 186 is located below the movable mold 15.

[0034] Under the action of the ejector rod in the movable mold 15 , the valve blank separates from the movable mold 15 and falls downward onto a plurality of heat-insulating rods 1819 , then slides obliquely to the left into the discharge port 1861 and stays in the receiving hopper 186 with the help of the baffle 1814 .

[0035] The telescopic end of the first cylinder 184 is driven to extend outward, and the traction plate 185 is pushed to the left with the help of the end block 189. At the same time, the pressure mechanism 13 drives the movable mold 15 to move downward to approach the fixed mold 14, and then continues to pull the traction plate 185 to the left with the help of the connecting rod 182, thereby driving the receiving hopper 186 to move to the left to be located on the left side of the movable mold 15. Then, the feeding mechanism 17 grabs the next qualified short material and puts it into the fixed mold 14 to start the next stamping molding with the help of the extrusion mechanism 12.

[0036] When the movable mold 15 is re-fitted with the fixed mold 14, the receiving hopper 186 moves to the left to the bottom, driving the telescopic end of the second cylinder 1812 to extend outward, and then pushing the roller 1817 with the help of the push head 1813, thereby driving the torsion shaft 1815 to rotate a certain angle with the help of the V-block 1816, and then driving the baffle 1814 to swing downward to leave the discharge port 1861. At this time, the valve blank slides down along the baffle 1814 into the discharge chute 1820, and is finally output outward to achieve automatic discharge.

[0037] Next, the pressure mechanism 13 drives the movable mold 15 to move upward to leave the fixed mold 14 again, and the receiving hopper 186 moves right again to receive the next valve blank. When the roller 1817 follows the receiving hopper 186 to move backward to leave the push head 1813, the torsion shaft 1815 uses its own counter-torsion force to drive the baffle 1814 to swing upward to seal the discharge port 1861, so as to facilitate the receipt of the next valve blank; the above process forms a cycle.

[0038] The release agent is loaded into the first tank body 191, pressurized air is introduced into the second tank body 197, and then graphite powder and engine oil are loaded into the third tank body 1913 and the stirring device 1914 is started to work continuously to fully mix the graphite powder and engine oil and prevent the graphite powder from settling.

[0039] When the movable mold 15 is about to be separated from the fixed mold 14, the first solenoid valve 196 and the second solenoid valve 1911 are opened, and the release agent will enter the first discharge pipe 193 through the sedimentation tank 192, and the pressurized air will enter the first discharge pipe 193 through the four-way valve 198 and the second discharge pipe 1910 and mix with the release agent before passing into the fixed mold 14 and the movable mold 15 to facilitate the demolding of the valve blank. The first one-way valve 194 can prevent the pressurized air from causing the release agent to flow back, and the first regulating valve 195 can adjust the output flow rate of the release agent; the release agent coming out of the first tank body 191 can automatically precipitate after entering the sedimentation tank 192, and then precipitate the impurities mixed in the release agent to prevent them from entering the first discharge pipe 193.

[0040] When the movable mold 15 and the fixed mold 14 are separated from each other, the third solenoid valve 1915 and the fourth solenoid valve 1918 are opened, and the graphite powder and the engine oil enter the fourth discharge pipe 199 through the third discharge pipe 1912. At the same time, the pressurized air enters the fourth discharge pipe 199 through the four-way 198 to mix with the graphite powder and the engine oil and input them into the liquid inlets of the two first atomizing nozzles 1823 and the liquid inlets of the two second atomizing nozzles 1824. Finally, the liquid outlets of the two first atomizing nozzles 1823 will spray the mixed spray of graphite powder and engine oil onto the movable mold 15 using pressurized air. The two second atomizing nozzles 1824 will use pressurized air to spray a mixed spray of graphite powder and engine oil onto the fixed mold 14 to cool it; in addition, the graphite powder will also lubricate the fixed mold 14 and the movable mold 15 to further facilitate demoulding. At the same time, the mixture of graphite powder and engine oil can effectively prolong the time that the engine oil adheres to the movable mold 15 to enhance the cooling effect; the second one-way valve 1916 can prevent the pressurized gas from causing the graphite powder and engine oil to flow back, and the second regulating valve 1917 can adjust the output flow rate of the graphite powder and engine oil.

[0041] The present invention can automatically move the formed valve blank outward to have an automatic discharging function, without the need for manual removal, thereby greatly reducing labor intensity and improving work efficiency, while effectively avoiding direct contact between operators and high-temperature valve blanks to completely eliminate safety hazards; in addition, the present invention also greatly improves the cooling effect of the movable mold and the fixed mold with the help of the cooling system 19, thereby reducing the difficulty of demolding the valve blank to ensure continuous production.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
