Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil supply devices, in particular to a lubricating oil supply device in a drawing tube. Background Art

[0002] The traditional process for the production of copper and copper alloy pipes generally adopts the process flow of ingot casting-heating-extrusion-tube rolling-straight strip stretching; red copper and white copper pipes also adopt the process flow of ingot casting-heating-extrusion-tube rolling-double-drawing-coil drawing; the disadvantages of the traditional production process are: high energy consumption, long process, low yield rate, and small unit weight of the stretched tube. The unit weight of the stretched tube produced by the former process is ≤100kg, and the unit weight of the stretched tube produced by the latter process can only reach 200-500kg.

By controlling the piston, the lubricant can be injected into the tube blank through the first injection tube and the second injection tube, thereby filling the space between the movable core head and the inner wall of the tube blank, which is convenient for replenishing the lubricant, simple to operate and highly practical.

[0004] Although the above patent can facilitate the replenishment of lubricants, the above device still has the following problems: because the device injects lubricating oil into the tube through the first injection tube and the second injection tube when lubricating oil is applied to the inside of the tube, and because the inner surface of the tube is circular, some of the lubricating oil sprayed to the top of the inside of the tube is easy to drip directly or a small part flows to the side, which can easily cause the lubricating oil to not flow evenly on the inner surface of the tube, so that the uniformity of the lubricating oil attached to the inner surface of the tube is reduced to a certain extent, and to a certain extent, it is easy to cause local oil shortage on the inner surface of the tube, so that the lubricating oil cannot lubricate the processed tube in time, so that the processing of the tube is affected to a certain extent. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

DETAILED DESCRIPTION

[0020] See also Figure 1-4, the present utility model provides a technical solution: a lubricating oil supply device for a drawn tube, including a drawing die 1. Inside the drawing die 1, there is a tube blank 2. Through the drawing die 1, the tube blank 2 can be drawn and processed. On one side of the drawing die 1, two symmetrical fixing rods 3 are fixedly connected. Inside the fixing rods 3, there is a connecting frame 4 that slides and extends outside the fixing rods 3. The cross-section of the connecting frame 4 is in a U-shape. On the side of the connecting frame 4 away from the fixing rods 3, a liquid storage tank 5 is fixedly connected. Lubricating oil can be stored inside the liquid storage tank 5. Inside the liquid storage tank 5, there is a push rod 6 that slides and extends outside the liquid storage tank 5. On one side of the push rod 6, a push plate 19 is fixedly connected. The push plate 19 is located inside the liquid storage tank 5. The push plate 19 can squeeze the lubricating oil inside the liquid storage tank 5. Inside the vertical rod of the connecting frame 4, there is a rotating liquid delivery pipe 15 that extends outside the connecting frame 4. One end of the liquid delivery pipe 15 close to the liquid storage tank 5 rotates through one side of the liquid storage tank 5 and extends into the liquid storage tank 5. A sealing ring is provided between the liquid delivery pipe 15 and the inside of the liquid storage tank 5, thereby improving the sealing performance between the liquid delivery pipe 15 and the liquid storage tank 5. On the outer surface of the liquid delivery pipe 15, a liquid discharge pipe 17 is fixedly connected. The inside of the liquid discharge pipe 17 is communicated with the inside of the liquid delivery pipe 15, so that the lubricating oil inside the liquid storage tank 5 is discharged onto the inner surface of the tube blank 2 through the inside of the liquid delivery pipe 15 and the liquid discharge pipe 17, enabling the device to supply lubricating oil to the inside of the tube blank 2 more smoothly. Inside the horizontal rod on the lower side of the connecting frame 4, there is a rotating shaft 10 that extends outside the connecting frame 4. On the top of the rotating shaft 10, a first bevel gear 11 is fixedly connected. On the outer surface of the liquid delivery pipe 15, a second bevel gear 12 is fixedly connected.

[0021] Further, the outer surface of the first bevel gear 11 is meshed and connected with the outer surface of the second bevel gear 12.

At the bottom of the rotating shaft 10, a gear 9 is fixedly connected. On the side of the transmission frame 8 close to the gear 9, there are teeth. The transmission frame 8 is meshed and connected with the surface of the gear 9 through the teeth.

[0023] After the staff makes the infusion tube 15 slide into the interior of the tube blank 2, the staff holds the connecting frame 4 with one hand and pushes the push rod 6 with the other hand, so that the push rod 6 discharges the lubricating oil from the interior of the infusion tube 15 to the inner surface of the tube blank 2 through the discharge pipe 17 through the push plate 19. At the same time, through the movement of the push rod 6, the push rod 6 drives the transmission frame 8 to move through the connecting rod 7, and the transmission frame 8 drives the gear 9 to rotate through the teeth, so that the gear 9 drives the infusion tube 15 to rotate through the rotating shaft 10, the first bevel gear 11 and the second bevel gear 12. During the discharge process of the lubricating oil, the infusion tube 15 can drive the discharge pipe 17 to rotate, and the lubricating oil discharged to the inner surface of the tube blank 2 through the discharge pipe 17 can be more uniform, and the inner surface of the tube blank 2 can be more evenly supplied with oil, so that the staff can use the device more conveniently.

[0024] Furthermore, a sealing plate 18 is fixedly connected to the outer surface of the liquid infusion tube 15 , and the sealing plate 18 can seal the inside of the tube blank 2 to a certain extent, and reduce the outflow of lubricating oil inside the tube blank 2 to a certain extent.

[0025] Furthermore, a collecting box 13 is provided on the top of the lower fixing rod 3 , and the lubricating oil inside the processed tube blank 2 can be collected through the collecting box 13 .

[0026] Furthermore, a mounting block 16 is fixedly connected to the top of the lower fixing rod 3, and a mounting groove 14 is opened on one side of the collecting box 13. The surface of the mounting block 16 is slidably connected to the inside of the mounting groove 14. The cross-sections of the mounting groove 14 and the mounting block 16 are both trapezoidal. By making the cross-sections of the mounting groove 14 and the mounting block 16 both trapezoidal, the position of the collecting box 13 can be positioned, and to a certain extent, the collecting box 13 can be installed and disassembled more smoothly, and the staff can use the device more conveniently.

[0027] Working principle: For this type of lubricating oil supply device for drawing tubes, the staff first slides the infusion tube 15 into the interior of the tube blank 2, and then holds the connecting frame 4 with one hand and pushes the push rod 6 with the other hand, so that the push rod 6 discharges the lubricating oil from the interior of the infusion tube 15 to the inner surface of the tube blank 2 through the discharge pipe 17 through the push plate 19. At the same time, the push rod 6 moves, so that the push rod 6 drives the transmission frame 8 to move through the connecting rod 7, so that the transmission frame 8 drives the gear 9 to rotate through the teeth, so that the gear 9 passes through the rotating shaft 10 and the first cone The bevel gear 11 and the second bevel gear 12 drive the infusion tube 15 to rotate, so that during the discharge process of the lubricating oil, the infusion tube 15 can drive the discharge tube 17 to rotate, and the lubricating oil discharged to the inner surface of the tube blank 2 through the discharge tube 17 can be more uniform. The cross-sections of the mounting groove 14 and the mounting block 16 are both trapezoidal, so that the position of the collecting box 13 is positioned, and to a certain extent, the collecting box 13 can be installed and disassembled more smoothly, and the lubricating oil inside the processed tube blank 2 can be collected through the collecting box 13.
