The first connecting ring is welded to the center of the upper top surface of the outside of the working cylinder. The first connecting ring is annular. The guide ring is installed inside the working cylinder and is connected to a sealing ring. One end of the guide ring is flush with the inner upper top surface of the working cylinder to guide and support the piston rod. The piston rod is fixed by a set screw. The piston is sleeved on the outer side of the set screw and the top end of the piston rod. There is a space between the piston and the guide ring. There is a sealing ring connected to prevent oil leakage. The center of the piston rod cylinder is a large chamber, which is composed of a long hollow cylinder and a hollow sphere.

Four identical small piston rods are distributed at 90° intervals around the piston rod. The small piston rod has the same structure as the piston rod.

[0009] Furthermore, the feeding device includes: a frame B, a motor D, a lead screw, a bearing seat C, a slider, a long shaft, and a bearing seat D; the base of the frame B is a frame structure, and an I-shaped steel plate is welded on the left and right ends of the top surface of the base, and the length is the same as the length of the base. There are two rubber pads above the two steel plates near the inner side, and the heavy aluminum rod rolls onto the two rubber pads through the rotating blanking device. Two square plates are welded on the left I-shaped steel plate, and the center of each square plate is connected to the buffer vibration reduction device. The first connecting rings of the two buffer vibration reduction devices are connected to a square plate, and there is a rubber pad with the same curvature as the heavy aluminum rod on the square plate. There are two buffer vibration reduction devices below the middle of the heavy aluminum rod, one end of which is installed on the steel plate under the rubber pad, and the other end is fixedly installed on the upper end surface of the I-shaped steel. The four buffer vibration reduction devices simultaneously play the role of buffering and shock absorption, and the base of the motor D is fixedly installed on the frame with bolts.

The two sides of the long axis are installed on the bearing seat D through bearings, and the base of the bearing seat D is fixedly installed on the upper end surface of the frame B with bolts, and an L-shaped square bar is welded at the top center of the slider; when the heavy aluminum rod rolls onto the two rubber pads through the U-shaped baffle of the rotating blanking device, the four buffering and vibration reduction devices simultaneously play a role of buffering and shock reduction. After the motor D is energized, the lead screw is driven to rotate through the coupling, so that the slider installed with the nut moves back and forth, and the L-shaped square bar pushes the heavy aluminum rod into the feeding port of the heating device.

[0010] Furthermore, when the motor A of the stepping conveyor device is energized, it drives the pulley on the left to rotate, and transmits power to the pushing device on the right through the V-belt on the pulley. The pushing devices on both sides work simultaneously. Each rotation of the pulley drives the connecting rod to move, thereby driving the fork rod to move each aluminum rod forward to the next baffle. The stepping conveyor device transmits the heavy aluminum rod to the conveying device. When the motor B of the conveying device drives the first roller to rotate, the second roller connected to the first roller through the V-belt can also rotate, thereby driving all the rollers to rotate, and transporting the heavy aluminum rod transported by the stepping conveyor to the rotating blanking device. After the motor C of the rotating blanking device is energized, the rotating shaft is driven to rotate through the coupling, thereby driving the U-shaped baffle to rotate, and the heavy aluminum rods transmitted by the conveying device are rotated 120° along the axis of the rotating shaft and fall onto the feeding device in sequence. The heavy aluminum rods are transported in sequence by the rotating blanking device to prevent accumulation. When the heavy aluminum rods fall onto the feeding device, the buffer and vibration reduction device is in a compression stroke, and the pre-charge pressure of the first-stage pressure air chamber is smaller than that of the second-stage pressure air chamber. When the load increases, the relative distance between the first connecting ring and the second connecting ring is shortened, causing the piston to move upward, and the oil in the cylinder is compressed and forced to pass through the one-way valve and The damping hole flows to the small rod chamber, the volume of the oil cylinder becomes smaller, and the volume of the small rod chamber becomes larger. At this time, the oil in the four small piston rods compresses the first-stage pressure air chamber through the rubber oil-gas diaphragm, and the gas volume of the first-stage pressure air chamber decreases and the pressure increases. When the load increases to make the air pressure in the first-stage pressure air chamber exceed the air pressure in the second-stage pressure air chamber, the piston continues to move upward, and the oil further moves to the rod chamber of the piston rod toward the second-stage pressure air chamber, compressing the second-stage pressure air chamber through the rubber oil-gas diaphragm, thereby alleviating the impact. After the motor D of the feeding device is energized, the lead screw is driven to rotate through the coupling, so that the slider on which the nut is installed moves back and forth, and the L-shaped square bar pushes the heavy aluminum rod in The inlet of the heating device, when the heavy aluminum rod is pushed away, the buffer vibration reduction device is in the telescopic stroke, when the load is reduced, the force on the piston is reduced accordingly, and the gas pressure in the second-stage pressure air chamber acts on the piston through the oil, forcing the piston to move downward, the relative distance between the first connecting ring and the second connecting ring increases, the one-way valve is closed, and the oil flows from the rod cavity of the piston rod to the cylinder only through the damping hole, the volume of the cylinder increases, and the volume of the rod cavity becomes smaller. When the load is reduced to make the air pressure in the second-stage pressure air chamber lower than the air pressure in the first-stage pressure air chamber, the oil in the four small piston rods also flows to the cylinder through the corresponding damping holes, generating a large damping force.It plays the role of buffering and vibration reduction.

[0028] like Figure 1 , 2, 3, 4, 5, 6, 7, 8, 9, and 10, a working method of a heavy-duty aluminum rod continuous feeding device with adjustable buffering and vibration reduction, with specific steps as follows: when the motor A15 of the stepping conveyor 1 is energized, it drives the pulley 131 on the left to rotate, and transmits power to the pushing device 13 on the right through the V-belt 16 on the pulley 131. The pushing devices 13 on both sides work simultaneously. Each rotation of the pulley 131 drives the connecting rod 132 to move, thereby driving the fork rod 14 to move each aluminum rod forward to the next baffle. The stepping conveyor 1 transmits the heavy-duty aluminum rod 12 to the conveying device 2. When the motor B23 of the conveying device 2 drives the first When the roller 24 rotates, the second roller 24 connected to the first roller 24 through the V-belt can also rotate, thereby driving all the rollers 24 to rotate, and the heavy aluminum rod 12 transported by the stepping conveyor 1 is transported to the rotating blanking device 3.

When the load increases, the relative distance between the first connecting ring 42 and the second connecting ring 413 is shortened, causing the piston 45 to move upward, and the oil in the oil cylinder 48 is compressed and forced to flow through the one-way valve 46 and the damping hole 47 to the small rod chamber. The volume of the oil cylinder 48 decreases, and the volume of the small rod chamber increases. At this time, the oil in the four small piston rods 441 compresses the first-stage pressure air chamber 49 through the rubber oil-gas diaphragm 411. The gas volume of the first-stage pressure air chamber 49 decreases and the pressure increases. When the load increases to make the first stage When the air pressure in the pressure chamber 49 exceeds the air pressure in the second-stage pressure chamber 410, the piston 45 continues to move upward, and the oil further moves toward the rod cavity of the piston rod 44 toward the second-stage pressure chamber 410, and compresses the second-stage pressure chamber 410 through the rubber oil-gas diaphragm 411, thereby alleviating the impact.

The volume of the oil cylinder 48 increases and the volume of the rod cavity decreases. When the load is reduced to make the air pressure in the second-stage pressure chamber 410 lower than the air pressure in the first-stage pressure chamber 49, the oil in the four small piston rods 441 also flows to the oil cylinder 48 through the corresponding damping holes 47, generating a large damping force, which plays a role in buffering and vibration reduction.

The left and right ends of the lead screw (53) are connected by bearings.

After the motor D (52) is powered on, the lead screw (53) is driven to rotate through the coupling, so that the slider (55) on which the nut is installed moves forward and backward, and the L-shaped square bar pushes the heavy aluminum bar (12) into the feeding port of the heating device (6). ; 2. The working method of the heavy aluminum bar continuous feeding device with adjustable buffering and vibration reduction as claimed in claim 1 is characterized by: When the motor A (15) of the stepping conveyor (1) is energized, it drives the left pulley (131) to rotate, and transmits power to the right push device (13) through the V-belt (16) on the pulley (131). The push devices (13) on both sides work simultaneously. Each rotation of the pulley (131) drives the connecting rod (132) to move, thereby driving the fork rod (14) to move each aluminum rod forward to the next baffle. The stepping conveyor (1) transfers the heavy aluminum rod (12) to the conveyor (2). When the motor B (23) of the conveyor (2) drives the first roller (24) to rotate, the second roller (24) connected to the first roller (24) through the V-belt can also rotate, thereby driving all the rollers. The cylinder (24) rotates to transport the heavy aluminum rod (12) transported by the stepping conveying device (1) to the rotating blanking device (3). When the motor C (32) of the rotating blanking device (3) is energized, the rotating shaft (33) is driven to rotate through the coupling, thereby driving the U-shaped baffle (35) to rotate, and the heavy aluminum rod (12) transmitted from the conveying device (2) is rotated 120 degrees along the axis of the rotating shaft (33) and sequentially falls onto the feeding device (5). The heavy aluminum rod (12) is sequentially transported by the rotating blanking device (3) to prevent accumulation. When the heavy aluminum rod (12) falls onto the feeding device (5), the buffer vibration reduction device (4) is in the compression stroke, and the first-stage pressure air chamber (49) is larger than the second-stage pressure air chamber (41 0) has a small pre-charged air pressure. When the load increases, the relative distance between the first connecting ring (42) and the second connecting ring (413) shortens, causing the piston (45) to move upward, and the oil in the oil cylinder (48) is compressed and forced to flow through the one-way valve (46) and the damping hole (47) to the small rod chamber. The volume of the oil cylinder (48) decreases, and the volume of the small rod chamber increases. At this time, the oil in the four small piston rods (441) compresses the first-stage pressure chamber (49) through the rubber oil-gas diaphragm (411). The gas volume of the first-stage pressure chamber (49) decreases and the pressure increases. When the load increases to the point where the air pressure in the first-stage pressure chamber (49) exceeds the air pressure in the second-stage pressure chamber (410), the piston (45) continues to move upward, and the oil further flows to the first-stage pressure chamber (49). The rod cavity of the piston rod (44) moves toward the second-stage pressure air chamber (410), and the second-stage pressure air chamber (410) is compressed through the rubber oil-gas diaphragm (411), thereby alleviating the impact. After the motor D (52) of the feeding device (5) is energized, the lead screw (53) is driven to rotate through the coupling, thereby causing the slider (55) on which the nut is installed to move forward and backward. The L-shaped square bar pushes the heavy aluminum rod (12) into the feeding port of the heating device (6). When the heavy aluminum rod (12) is pushed away, the buffer vibration reduction device (4) is in the telescopic stroke. When the load decreases, the force on the piston (45) decreases accordingly. The gas pressure in the second-stage pressure air chamber (410) acts on the piston (45) through the oil, forcing the piston (45) to move downward.The relative distance between the first connecting ring (42) and the second connecting ring (413) increases, the one-way valve (46) is closed, and the oil flows from the rod chamber of the piston rod (44) to the oil cylinder (48) only through the damping hole (47). The volume of the oil cylinder (48) increases, and the volume of the rod chamber decreases. When the load is reduced to make the air pressure in the second-stage pressure air chamber (410) lower than the air pressure in the first-stage pressure air chamber (49), the oil in the four small piston rods (441) also flows to the oil cylinder (48) through the corresponding damping holes (47), generating a large damping force, which plays a role in buffering and reducing vibration.
