Description

Technical Field

[0001] The present invention relates to the technical field of tip rolling machines, and particularly to a multi-station high-efficiency large-scale tip rolling machine. Background Art

[0002] A tip rolling machine is a mechanical device for wire drawing machines and cold drawing production equipment. During the processing of the tip rolling machine, by repeatedly drawing the raw material, plastic deformation can occur to the raw material under the action of force. This plastic deformation helps to improve the ductility of the raw material and makes it easier to form a tip.

[0003] The tip rolling machine is an auxiliary device for copper, aluminum, and iron wire drawing equipment. This machine consists of rolling rolls and a reduction drive. The rolling rolls have a smooth cylindrical or grooved surface. When the upper and lower rolling rolls rotate inward by 50°, the steel wire is swallowed and rolled thinner, but then the rolling rolls immediately rotate outward. At this time, the rolled thinner steel wire is spit out. After the steel wire is swallowed and spit out two or three times, the tip pressing of one groove hole is completed. Proceeding in this way in turn until the requirements are met. During operation, the steel wire needs to rotate to prevent it from being rolled into an oval shape.

[0004] At present, basically all the tip rolling machines on the market have only one station, with low working efficiency. And using multiple tip rolling machines to work together increases the floor area and cost. During the tip rolling process, different repeated drawings are required. It is very difficult to always keep the raw material in the middle position of the rolling rolls or to keep the raw material in a straight line during the drawing process, which easily causes uneven stress on the four sides of the raw material and makes the tip of the raw material oval-shaped. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-station high-efficiency large-scale tip rolling machine to solve the problems of low efficiency of the tip rolling machine on the current market and uneven stress on the processed raw material as proposed in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A multi-station high-efficiency large-scale tip rolling machine, including rolling rolls and a servo motor. The rolling rolls are arranged on the body of the tip rolling machine, and the servo motor is connected to the rolling rolls through a transmission assembly. A metal wire is inserted into the rolling rolls, and a hoop for limiting the metal wire is wrapped outside the metal wire. A rotating ring for rotating the metal wire is installed on the hoop.

[0007] Preferably, an installation frame is installed on the side of the body of the tip rolling machine. The installation frame is in an "L" shape, and moving grooves and sliding grooves are respectively and equally spaced on both sides of the installation frame.

[0008] Preferably, an electric telescopic rod II slides inside the sliding groove. A support plate is installed at the output end of the electric telescopic rod II. An electric telescopic rod I slides inside the moving groove, and the output end of the electric telescopic rod I is installed with the support plate.

[0009] Preferably, the support plate is in an "L" shape, and through holes are equidistantly arranged on one side of the support plate close to the moving groove, and the through holes correspond to the moving grooves one by one.

[0010] Preferably, the length of the moving groove is greater than the length of the rolling roller, and the length of the sliding groove is greater than the diameter of the rolling roller.

[0011] Preferably, a hydraulic cylinder is installed at one end of the support plate close to the second electric telescopic rod, and a toothed row is installed at the output end of the hydraulic cylinder.

[0012] Preferably, a rotating ring is rotatably connected to the side of the rolling tip machine body close to the support plate, a gear is installed on the outer side of the rotating ring, the gear meshes with the toothed row, and vertical grooves are arranged on both the upper and lower sides of the gear.

[0013] Preferably, an "L"-shaped connecting rod slides inside the groove, the bottom end of the connecting rod is fixed to the clamp, and the upper and lower two clamps are fixed by screws.

[0014] Preferably, a servo motor is installed on the rolling tip machine body, the transmission assembly includes a first transmission chain and a second transmission chain, the output end of the servo motor is installed with the first transmission chain through a speed reducer, and the first transmission chain is connected to the rolling roller through the second transmission chain.

[0015] Preferably, the middle of the gear is a hollow structure, and a metal wire rod passes through the middle of the gear and the through hole.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: [[ID= 23]]

[0017] 1. Multiple rolling rollers are arranged on the rolling tip machine body, the transmission assembly includes a first transmission chain and a second transmission chain, the synchronous operation of the multiple rolling rollers is realized through the transmission functions of the first transmission chain and the second transmission chain, and the rotation of the metal wire rod during the rolling tip process is realized through the cooperation of the gear and the rotating ring. There is no need for manual rotation of the metal wire rod by personnel. The rotation of the metal wire rod makes it evenly rolled to a tip, avoiding uneven surfaces on the metal wire rod during the rolling tip process.

[0018] 2. The first electric telescopic rod slides inside the moving groove, and the second electric telescopic rod slides inside the sliding groove. The cooperation of the second electric telescopic rod and the first electric telescopic rod enables the metal wire rod to expand and contract at the concave position and switch at the concave position. The support plate is arranged to synchronously roll the tips of the metal wire rods at multiple stations, improving the rolling tip efficiency and adapting to the high-efficiency production of modern factories.

[0019] 3. The connecting rod slides inside the groove, the connecting rod is fixed to the clamp, and a sponge is adhered to the inner side of the clamp. The clamp and the sponge can fix metal wire rods with different diameters. The two clamps are located on the upper and lower sides of the metal wire rod, keeping the metal wire rod in the middle position of the through hole, avoiding uneven stress caused by the deviation of the metal wire rod, preventing uneven rolling of the tip around the circumference, and further making the metal wire rod rolled to a round tip shape.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Please refer to Figures 1 - 8 , the present invention provides a technical solution:

[0031] A multi-station high-efficiency large-scale tip rolling machine, including a rolling roll 8 and a servo motor 7. The rolling roll 8 is arranged on the body 1 of the tip rolling machine. The servo motor 7 is connected to the rolling roll 8 through a transmission component. A metal wire 5 is inserted into the rolling roll 8. The servo motor 7 is installed on the body 1 of the tip rolling machine. The transmission component includes a first transmission chain 19 and a second transmission chain 20. The output end of the servo motor 7 is installed with the first transmission chain 19 through a speed reducer. The first transmission chain 19 is connected to the rolling roll 8 through the second transmission chain 20.

[0032] Insert the metal wire 5 into the concave position on the rolling roll 8. Start the servo motor 7. The operation of the servo motor 7 causes the transmission component to operate. The operation of the transmission component drives the multi-station rolling roll 8 to rotate. The rotation of the rolling roll 8 performs a tip rolling operation on the metal wire 5 at the concave position. The setting of the multi-station rolling roll 8 improves the working efficiency of the body 1 of the tip rolling machine. The model of the body 1 of the tip rolling machine is the ZJ-430 large drawing tip rolling machine.

[0033] A clamp 18 for limiting the metal wire 5 is wrapped around the outside of the metal wire 5. A rotating ring 15 for rotating the metal wire 5 is installed on the clamp 18. An L-shaped connecting rod 17 slides inside the groove 16. The top end of the connecting rod 17 is threadedly connected with a nut. The side of the nut is attached to the side of the gear 14. The bottom end of the connecting rod 17 is fixed to the clamp 18. The upper and lower clamps 18 are fixed by screws. The middle of the gear 14 is a hollow structure. The metal wire 5 passes through the middle of the gear 14 and the through hole 13. An L-shaped connecting rod 17 slides inside the groove 16. The bottom end of the connecting rod 17 is fixed to the clamp 18. The upper and lower clamps 18 are fixed by screws. The middle of the gear 14 is a hollow structure. The metal wire 5 passes through the middle of the gear 14 and the through hole 13.

[0034] Before performing the tip rolling work, first insert the metal wire 5 through the through hole 13 and the hollow position of the gear 14 into the concave position of the rolling roll 8. Then, push the clamp 18 towards the metal wire 5 by hand to make the clamp 18 snap onto the outside of the metal wire 5. Fix the upper and lower clamps 18 with screws to limit the metal wire 5. During the tip rolling process, the metal wire 5 needs to keep rotating during the stretching process. Start the hydraulic cylinder 11. The operation of the hydraulic cylinder 11 causes the tooth row 12 to move left and right. The left and right movement of the tooth row 12 pushes the gear 14, causing the gear 14 to rotate. The rotation of the gear 14 drives the rotating ring 15 to rotate synchronously. The rotating ring 15 drives the connecting rod 17, the clamp 18, and the metal wire 5 to rotate synchronously, thereby rotating the metal wire 5 and making the tip rolling around the metal wire 5 uniform.

[0035] On the side of the body 1 of the tip rolling machine, there is an installation frame 2. The installation frame 2 is of an "L" - shaped structure. On both sides of the installation frame 2, a moving groove 3 and a sliding groove 9 are respectively provided at equal intervals. Inside the sliding groove 9, there is a second electric telescopic rod 10 sliding. The output end of the second electric telescopic rod 10 is installed with a support plate 6. Inside the moving groove 3, there is a first electric telescopic rod 4 sliding. The output end of the first electric telescopic rod 4 is installed with the support plate 6. The support plate 6 is of an "L" - shaped structure. On the side of the support plate 6 close to the moving groove 3, through - holes 13 are provided at equal intervals. The through - holes 13 correspond to the moving grooves 3 one by one. The length of the moving groove 3 is greater than the length of the rolling roller 8, and the length of the sliding groove 9 is greater than the diameter of the rolling roller 8.

[0036] During the tip rolling process, the first electric telescopic rod 4 expands and contracts. The expansion and contraction of the first electric telescopic rod 4 drives the support plate 6 to move back and forth. By the back - and - forth movement of the support plate 6, the metal wire 5 is stretched and contracted. When the metal wire 5 needs to enter the next concave position after passing through a concave position of the rolling roller 8, the first electric telescopic rod 4 separates the metal wire 5 from the concave position. Then the second electric telescopic rod 10 starts. The second electric telescopic rod 10 makes the support plate 6 move left and right. The left - and - right movement of the support plate 6 moves the metal wire 5 to the next concave position. Then the first electric telescopic rod 4 makes the metal wire 5 stretch and contract at the concave position. When the support plate 6 moves left and right, it drives the first electric telescopic rod 4 to slide inside the moving groove 3. Through the settings of the first electric telescopic rod 4 and the second electric telescopic rod 10, the metal wires 5 at multiple workstations run synchronously, greatly improving the work efficiency and eliminating the need for manual adjustment of the position of the metal wire 5.
