Description

[0002] A manhole cover is used to cover a road or a deep well at home to prevent people or objects from falling. It can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc., and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] In the production process of aluminum alloy manhole covers, it is necessary to quench and cool the heated aluminum alloy profiles to form a strong compressive stress on the surface of the aluminum alloy. In the existing aluminum alloy profile quenching and cooling devices, most of them clamp the aluminum alloy profiles through air grilles and then cool them by air cooling. However, this quenching and cooling method has a fixed blowing angle, which is likely to cause uneven cooling on the surface of the aluminum alloy profiles, resulting in low strength of the quenched and cooled aluminum alloy profiles, and even deformation of the aluminum alloy profiles due to uneven cooling.

[0036] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The present invention provides a quenching and cooling device for processing and forming aluminum alloy manhole covers. During the cooling process of the aluminum alloy manhole covers, a rotating assembly drives the aluminum alloy profiles to rotate, maintaining uniform cooling of the aluminum alloy profiles and preventing deformation of the aluminum alloy profiles caused by uneven cooling.

[0038] Embodiment 1

[0039] Figures 1-3 Shown is a schematic structural diagram of the first embodiment of a quenching and cooling device for processing and forming aluminum alloy manhole covers according to the present invention. Please refer to Figures 1-3 In this embodiment, a quenching and cooling device for processing and forming aluminum alloy manhole covers includes a cooling box 100, a driving assembly 200, a rotating assembly 300, a clamping assembly 400, and a water cooling assembly 500.

[0040] A blower 110 is installed on the top of the cooling box 100. An air inlet 120 is provided on the top of the cooling box 100. Two slots 130 are respectively provided at the front end and the rear end of the top of the cooling box 100. A first connecting portion 140 is installed inside the rear slot 130. The two sides of the cooling box 100 are open, and the aluminum alloy profiles extend into the interior of the cooling box 100 from the rear of the cooling box 100 and are taken out from the front of the cooling box 100.

[0041] The driving assembly 200 is installed on the side wall of the cooling box 100. The driving assembly 200 includes a motor 210 installed on the side wall of the cooling box 100, a reciprocating threaded rod 220 rotatably connected to the side wall of the cooling box 100 and connected to the output end of the motor 210, and a moving frame 230 slidably located on the outer wall of the cooling box 100. By starting the motor 210 to drive the reciprocating threaded rod 220 to rotate, the reciprocating threaded rod 220 drives the moving frame 230 to move back and forth.

[0042] The rotating assembly 300 includes a rotating cylinder 310 rotatably connected inside the cooling box 100 and a second connecting portion 320 installed inside a slot 130 in the front and connected to the rotating cylinder 310. The second connecting portion 320 is connected to the driving assembly 200. The tail end of the rotating cylinder 310 is connected to the first connecting portion 140. When the moving frame 230 moves forward, it is connected to the second connecting portion 320, driving the second connecting portion 320 to drive the rotating cylinder 310 to rotate forward. The rotating cylinder 310 drives the aluminum alloy profile to rotate forward. When the moving frame 230 moves backward after moving forward in place, the backward movement drives the second connecting portion 320 to drive the rotating cylinder 310 to rotate backward. The rotating cylinder 310 drives the aluminum alloy profile to rotate backward until the moving frame 230 separates from the second connecting portion 320, and the rotating cylinder 310 and the aluminum alloy profile stop rotating.

[0043] The clamping assembly 400 includes two air grilles 410 symmetrically located inside the rotating cylinder 310 and a driving portion 420 installed on the side wall of the air grille 410. When the moving frame 230 moves forward and is not connected to the second connecting portion 320, the moving frame 230 drives the two air grilles 410 to approach each other, and the aluminum alloy profile is clamped between the two air grilles 410. When the moving frame 230 moves backward and separates from the second connecting portion 320, the moving frame 230 drives the two air grilles 410 to move away from each other.

[0044] The water cooling assembly 500 is installed on the side wall of the cooling box 100 and connected to the first connecting portion 140. The water cooling assembly 500 is connected to an external water supply device. When the rotating cylinder 310 rotates, it drives the first connecting portion 140 to drive the water cooling assembly 500 to spray water between the two clamping assemblies 400, cooperating with the air cooling of the fan 110 to mix water cooling to accelerate the cooling efficiency of the aluminum alloy profile.

[0045] Combined Figures 1-3, A quenching and cooling device for processing and forming an aluminum alloy manhole cover according to this embodiment, when in use, the aluminum alloy profile is fed into the interior of the cooling box 100 from the rear opening of the cooling box 100 and is located between the two air grilles 410. The motor 210 is started to drive the reciprocating threaded rod 220 to rotate, pushing the moving frame 230 forward. The moving frame 230 drives the two air grilles 410 to approach each other and clamp the aluminum alloy profile until the moving frame 230 is connected to the second connecting part 320. The blower 110 is started to blow air into the interior of the cooling box 100. The forward movement of the moving frame 230 drives the second connecting part 320 to drive the rotating cylinder 310 and the aluminum alloy profile to rotate forward. When the rotating cylinder 310 rotates, it drives the water cooling assembly 500 to spray water onto the surface of the aluminum alloy profile, and cooperates with the blower 110 to cool the aluminum alloy profile by air cooling and water cooling simultaneously. After the moving frame 230 moves forward in place, as the reciprocating threaded rod 220 continues to rotate, the moving frame 230 moves backward, driving the second connecting part 320 to drive the rotating cylinder 310 and the aluminum alloy profile to rotate in the reverse direction until the moving frame 230 is separated from the second connecting part 320. As the moving frame 230 moves backward and resets, the moving frame 230 drives the two air grilles 410 to move away from each other, and the cooled aluminum alloy profile is taken out from the front opening of the cooling box 100.

[0046] Embodiment 2

[0047] Figures 1-8 Shown is a structural schematic diagram of the second embodiment of a quenching and cooling device for processing and forming an aluminum alloy manhole cover according to the present invention. Please refer to Figures 1-8 , Different from the above embodiment, a quenching and cooling device for processing and forming an aluminum alloy manhole cover according to this embodiment further includes:

[0048] Two fixed frames 150 are symmetrically installed inside the cooling box 100. The first connecting part 140 includes a first gear 140a rotatably connected inside the slot 130 at the rear and a second pulley 140b rotatably connected to the side wall of the cooling box 100. A first pulley 140a-1 is installed on the side wall of the first gear 140a, and a threaded rod 140b-1 is installed on the side wall of the second pulley 140b. The first pulley 140a-1 and the second pulley 140b are connected by a belt.

[0049] A reciprocating threaded hole 230a is formed in the side wall of the moving frame 230. The reciprocating threaded rod 220 rotates through the reciprocating threaded hole 230a. A first flat rack 230b is installed at the top of one side of the moving frame 230. A guiding groove 160 is formed in the side wall of the cooling box 100. Two guiding plates 230c are symmetrically installed on the inner wall of the moving frame 230. The guiding plates 230c penetrate through the guiding groove 160 and extend into the interior of the cooling box 100. Among them, a second flat rack 230c-1 is installed at the bottom of the upper guiding plate 230c.

[0050] The rotary drum 310 includes two symmetrically arranged fixed sleeves 310a and a connecting rod 310b connected inside the fixed sleeves 310a. The two fixed sleeves 310a are respectively rotatably connected inside the two fixed brackets 150. Circular racks 310a-1 are installed on the outer walls of the two fixed sleeves 310a. The second connecting portion 320 includes a fourth gear 320a rotatably connected to the side wall of the cooling box 100, a third pulley 320b rotatably connected to the top of the cooling box 100, and a fifth gear 320c rotatably connected inside one of the front slots 130. A belt is connected between the fourth gear 320a and the third pulley 320b. A rotating rod 320b-1 is installed on the side wall of the third pulley 320b, and a third helical gear 320b-2 is installed at the other end of the rotating rod 320b-1. A fourth helical gear 320c-1 is installed on the side wall of the fifth gear 320c, and the fourth helical gear 320c-1 meshes with the third helical gear 320b-2. A connecting frame 310c is installed between the two fixed sleeves 310a. A third gear 310c-1 is installed on the side wall of the rear fixed sleeve 310a. A left-right threaded screw rod 310c-2 is rotatably connected inside the connecting frame 310c. A first helical gear 310c-3 is installed on the side wall of the third gear 310c-1, and a second helical gear 310c-4 is installed on the rod body of the left-right threaded screw rod 310c-2. The first helical gear 310c-3 meshes with the second helical gear 310c-4. Grating plates 410a are installed inside the air grilles 410. Fixed blocks 410b are installed on the side walls of the air grilles 410. First threaded holes 410b-1 are opened at the tops of the fixed blocks 410b. The left-right threaded screw rod 310c-2 rotates through the first threaded holes 410b-1. Two circular special-shaped racks 150a are symmetrically installed inside the cooling box 100 in the front and rear. The teeth inside the two circular special-shaped racks 150a are staggered. Second gears 310a-2 are rotatably connected to the side walls of the fixed sleeves 310a. The two second gears 310a-2 respectively mesh with the two circular special-shaped racks 150a. When the moving frame 230 moves forward, the first flat rack 230b meshes with the fourth gear 320a. The forward movement of the reciprocating threaded hole 230a drives the fourth gear 320a to rotate. The fourth gear 320a drives the third pulley 320b and the third helical gear 320b-2 to rotate. The third helical gear 320b-2 drives the fourth helical gear 320c-1 and the fifth gear 320c to rotate. The fifth gear 320c drives the front circular rack 310a-1 and the two fixed sleeves 310a to rotate. The fixed sleeves 310a drive the connecting frame 310c to rotate, and then drive the two air grilles 410 and the aluminum alloy profile to rotate. When the moving frame 230 moves forward to the in-place position, as the reciprocating screw rod 220 continues to rotate, the backward movement of the first flat rack 230b drives the fourth gear 320a to reverse, and then drives the fifth gear 320c to reverse. The fifth gear 320c drives the front circular rack 310a-1 and the two fourth gears 320a and the aluminum alloy profile to reverse.

[0051] The driving part 420 includes a sixth gear 420a rotatably connected to the side wall of the air grille 410 and a conveying roller 420b rotatably connected inside the air grille 410. The two sixth gears 420a are respectively engaged with the two second gears 310a-2. A fifth helical gear 420a-1 is installed on the side wall of the sixth gear 420a, and a sixth helical gear 420b-1 is installed on the side wall of the conveying roller 420b. The fifth helical gear 420a-1 is engaged with the sixth helical gear 420b-1. In the initial state, the third gear 310c-1 is located between the two guide plates 230c and engaged with the second flat rack 230c-1. When the moving frame 230 moves forward, the second flat rack 230c-1 drives the third gear 310c-1 and the first helical gear 310c-3 to rotate. The first helical gear 310c-3 drives the second helical gear 310c-4 and the left-right hand threaded rod 310c-2 to rotate. The rotation of the third gear 310c-1 uses the screw structure to push the two air grilles 410 closer to each other and clamp the aluminum alloy profile until the first flat rack 230b is engaged with the fourth gear 320a. At this time, the third gear 310c-1 separates from the inside of the two guide plates 230c. When the moving frame 230 moves backward until the first flat rack 230b is separated from the fourth gear 320a, the third gear 310c-1 is located between the two guide plates 230c. As the moving frame 230 and the second flat rack 230c-1 move backward, the second flat rack 230c-1 drives the third gear 310c-1 and the first helical gear 310c-3 to reverse, and then drives the left-right hand threaded rod 310c-2 to reverse, pushing the two air grilles 410 away from each other. When the two air grilles 410 are close to clamp the aluminum alloy profile, the two second gears 310a-2 are respectively engaged with the two sixth gears 420a. When the two fixed sleeves 310a rotate, the air grille 410 rotates following the fixed sleeve 310a. The circular special-shaped rack 150a drives the second gear 310a-2 to rotate, and the second gear 310a-2 drives the sixth gear 420a to rotate. Because the internal teeth of the two circular special-shaped racks 150a are staggered, when the front circular special-shaped rack 150a is engaged with the front second gear 310a-2, at this time the rear circular special-shaped rack 150a is separated from the rear second gear 310a-2. The front circular special-shaped rack 150a drives the front second gear 310a-2 to rotate, and then drives the lower sixth gear 420a and the fifth helical gear 420a-1 to rotate. The lower fifth helical gear 420a-1 drives the lower sixth helical gear 420b-1 and the conveying roller 420b to rotate, pushing the aluminum alloy profile to move forward slightly. When the rear circular special-shaped rack 150a is engaged with the rear second gear 310a-2, the front circular special-shaped rack 150a is separated from the front second gear 310a-2. The rear circular special-shaped rack 150a drives the rear second gear 310a-2 to rotate, and then drives the upper sixth gear 420a and the fifth helical gear 420a-1 to rotate.The upper fifth helical gear 420a-1 drives the upper sixth helical gear 420b-1 and the conveying roller 420b to rotate, pushing the aluminum alloy profile to move slightly backward, so that the aluminum alloy profile moves back and forth during rotation, preventing the position of the aluminum alloy profile from being fixed, so that the part of the aluminum alloy profile blocked by the grating plate 410a is unevenly cooled.

[0052] The water cooling assembly 500 includes a pressure tank 510 installed on the side wall of the cooling tank 100, a piston 520 located inside the pressure tank 510, a first delivery pipe 530 installed on the side wall of the pressure tank 510, and a second delivery pipe 540 installed on the other side wall of the pressure tank 510 and extending into the cooling tank 100. A fixed rod 520a is installed on the side wall of the piston 520, and a second threaded hole 520b is provided at the side end of the fixed rod 520a. The threaded rod 140b-1 rotates and extends into the second threaded hole 520b. A first one-way valve 530a is installed on the body of the first delivery pipe 530, and a second one-way valve 540a is installed on the body of the second delivery pipe 540. The other end of the second delivery pipe 540 is installed with a spray head 540b. The other end of the first delivery pipe 530 is connected to an external water supply device. When the two fixed sleeves 310a rotate, the rear circular rack 310a-1 drives the first gear 140a and the first pulley 140a-1 to rotate. The first pulley 140a-1 drives the second pulley 140b and the threaded rod 140b-1 to rotate by means of a belt. When the threaded rod 140b-1 rotates forward, it pushes the fixed rod 520a and the piston 520 to move into the pressure tank 510. At this time, the first one-way valve 530a closes, and the second one-way valve 540a opens. The water inside the pressure tank 510 is conveyed to the spray head 540b through the second delivery pipe 540 and sprayed onto the two air grilles 410 through the spray head 540b to perform water cooling on the aluminum alloy profile. When driving the fixed sleeve 310a and the circular rack 310a-1 to rotate in the reverse direction, the rear circular rack 310a-1 drives the first gear 140a to rotate in the reverse direction, and then drives the threaded rod 140b-1 to rotate in the reverse direction, pushing the piston 520 to move outside the pressure tank 510. At this time, the second one-way valve 540a closes, and the first one-way valve 530a opens. The water of the external water supply device is conveyed into the pressure tank 510 through the first one-way valve 530a for the next cooling.

Start the fan 110. As the moving frame 230 moves forward, the first flat rack 230b drives the fourth gear 320a to rotate forward, then drives the two fixed sleeves 310a and the aluminum alloy profile to rotate forward. The circular rack 310a-1 at the rear drives the threaded rod 140b-1 to rotate, pushing the piston 520 into the pressure tank 510, and spraying the water inside the pressure tank 510 through the second one-way valve 540a between the two air grilles 410, cooperating with the fan 110 to perform air cooling and water cooling on the aluminum alloy profile. When the moving frame 230 moves forward in place, the reciprocating threaded rod 220 continues to rotate, the moving frame 230 moves backward, the first flat rack 230b drives the fourth gear 320a to rotate backward, then drives the two fixed sleeves 310a and the aluminum alloy profile to rotate backward until the first flat rack 230b separates from the fourth gear 320a and the fixed sleeve 310a stops rotating. As the moving frame 230 continues to move backward, the third gear 310c-1 enters between the two guide plates 230c, and the second flat rack 230c-1 moves backward to drive the third gear 310c-1 and the left-right threaded rod 310c-2 to rotate, pushing the two air grilles 410 away from each other, and the cooled aluminum alloy profile can be taken out between the two air grilles 410.
