Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing, and more specifically to a stainless steel pipe production device for a condenser. Background Art

[0002] Tube drawing is a crucial link in the steel pipe processing process. It not only involves the forming quality of the steel pipe, but also directly affects the dimensional accuracy, surface finish and mechanical properties of the final product. In the steel pipe manufacturing industry, the tube drawing process is usually used to improve the inner and outer diameter tolerances of the pipe, improve the straightness and wall thickness uniformity of the pipe, and also enhance the mechanical properties of the material, such as strength and toughness; Specifically, the tube drawing process is a process in which a steel tube blank (or tube blank) heated to a certain temperature is passed through a series of dies with gradually decreasing diameters (i.e., die drawing), and an external pulling force is used to force the steel tube through these dies, thereby reducing its outer diameter and increasing its length. In this process, the steel tube is squeezed by the inner wall of the die, and the material undergoes plastic deformation, which not only reduces the outer diameter, but also reduces the wall thickness accordingly to meet the predetermined specification requirements. For example, a Chinese invention patent with announcement number CN112453083B discloses a steel tube drawing and stretching production device, which realizes the automated operations of automatic tube loading, tube drawing, lubrication and tube placing, reduces the setting of driving components, saves energy consumption, can apply lubricating oil while drawing, and automatically feeds the next tube after drawing, thereby improving work efficiency.

[0003] However, there are still some shortcomings in its use: a certain amount of lubricating oil is injected into the oil pipe, and the surface of the steel pipe can be automatically oiled with the rotation of the cloth brush, but its service life is short and the oil output is small. It needs to be refilled regularly, and the lubrication is insufficient, which is not conducive to the continuous operation of the equipment. In addition, the surface of the steel pipe after the pipe is pulled out is adhered to oil stains, and an additional cleaning process is required, which undoubtedly increases manpower or material resources.

[0004] Therefore, the present invention proposes a stainless steel tube production device for a condenser to realize the automatic integrated operation of oil replenishment on the tube and oil spraying after tube pulling, as well as cleaning the steel tube after tube pulling, so as to ensure the continuous and efficient operation of stainless steel tube production.

The moving position of the clamping head 603 is determined by the hitting situation of the signal receiver 605.

[0030] Working principle of the present invention: The preheated steel pipe is introduced from the feed port at the top of the pipe rack 1, and then slides down along the slope of the pipe rack 1, and finally stops on the top wall of the transmission box 401 and aligns with the shaping hole of the template 502 under the blockage of the material blocking plate 3, completing the automatic feeding of the steel pipe; Next, the telescopic end of the main hydraulic cylinder 602 extends and carries the clamping head 603 and the second L-shaped rack 604 to move to the right. The second L-shaped rack 604 that moves to the right drives the first L-shaped rack 402 to move in the opposite direction through the first flat gear 405, so that the first L-shaped rack 402 can be gradually retracted to the left into the transmission cavity of the transmission box 401. At the same time, the piston rod 403 and the push plate 404 connected to the first L-shaped rack 402 move to the left together. The piston rod 403 that moves to the left causes the liquid cavity of the transmission box 401 to expand and form a negative pressure, so that the lubricating oil provided by the feed source is automatically introduced into the liquid cavity of the transmission box 401 through the one-way feed valve 407 for automatic oil replenishment. At the same time, the push plate 404 that moves to the left pushes the steel pipe to one side of the plastic pipe assembly 5, so that its end can be pressed through the shaping hole of the template 502 and can be in contact with the clamping head. 603 docking, when the signal receiver 605 on the right is aligned and receives the target signal emitted by the signal transmitter 606, it is determined that the clamping head 603 has reached the clamping area of ​​the steel pipe at this time, and the signal receiver 605 outputs the target determination information to the controller 10, and the controller 10 receives the target determination information and outputs the control instruction to the auxiliary hydraulic cylinder 6032, and then controls the telescopic end of the auxiliary hydraulic cylinder 6032 to extend and carry the straight rack 6033 to move right, and the right-moving straight rack 6033 drives the second flat gears 6034 on both sides thereof to rotate in the opposite direction from inside to outside with the positioning shaft 6035 as the axis, so that the inner clamping plate 6036 connected to the second flat gear 6034 moves closer to the side of the outer clamping plate 6037, until the inner clamping plate 6036 cooperates with the outer clamping plate 6037 to clamp the end wall of the steel pipe, so as to complete the clamping of the steel pipe; Subsequently, the telescopic end of the main hydraulic cylinder 602 retracts and moves the clamping head 603 and the second L-shaped rack 604 to the left. The clamping head 603 continuously pulls the clamped steel pipe to the left, so that the steel pipe gradually passes through the shaping hole of the template 502 to perform the pipe pulling operation. During this period, the second L-shaped rack 604 that moves to the left drives the first L-shaped rack 402 to the right through the first flat gear 405 and gradually withdraws from the transmission chamber of the transmission box 401. The piston rod 403 and the push plate 404 connected to the first L-shaped rack 402 move to the right together to reset. The piston rod 403 that moves to the right compresses the liquid chamber of the transmission box 401. The lubricating oil in the liquid cavity is injected into the injection pipe 409 through the one-way discharge valve 408 and the conduit, and then introduced into the spray ring pipe 411 through the reversing valve 410. Finally, the lubricating oil flows out through the oil outlet hole on the inner wall of the transmission box 401. On the one hand, it continuously lubricates the steel pipe passing through the mold to reduce the friction during pipe pulling. On the other hand, the continuously flowing lubricating oil can reduce the heat generated by excessive friction and reduce wear. The right-moving push plate 404 will withdraw and vacate the top space of the transmission box 401, so that the nearest steel pipe on the slope of the pipe rack 1 can enter to wait for the next cycle of pipe pulling operation. Finally, when the signal transmitter 606 is aligned with the left signal receiver 605, it is determined that the pipe pulling operation is completed, and the clamping head 603 releases the pipe, so that the steel pipe that has completed the pipe pulling falls freely into the cleaning tank 701. During the stage of oil replenishment and pipe pulling and oil injection, the first flat gear 405 keeps rotating, and the bevel gear 803 connected to the end of the rotating shaft 406 and the transmission shaft 801 can transmit the transmission force of the first flat gear 405 to the pulley 804, and the pulley 804 connected to the end of the transmission shaft 801 and the turntable 703 is connected by a synchronous belt, so that the turntable 703 and the brush plate 702 can rotate synchronously to perform rotational water washing on the steel pipe that falls into the cleaning tank 701 to remove oil stains on the surface of the pipe.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
