Description

Technical Field

[0001] The utility model relates to a servo rib expanding machine, belonging to the technical field of barrel making equipment. Background Art

[0002] In the manufacturing process of steel barrels, rib expanding is an essential process for steel barrel processing. The quality of rib expanding is related to whether the final strength and stiffness of the steel barrel can meet the usage requirements. For the existing rib expanding machines, the movement of the expanding head is controlled by a hydraulic system, which not only increases the overall weight of the equipment, but also there is a risk of aging and oil leakage in the hydraulic pipeline. Not only does the equipment occupy a large area and have a high processing cost, but also the service life of the overall equipment is reduced. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a servo rib expanding machine. The servo rib expanding machine uses a servo motor to drive the movement of the machine box and the expanding head, omitting the original hydraulic pipeline, which not only reduces the processing cost, but also improves the service life of the equipment.

[0004] To solve the above problems, the specific technical solution of the utility model is as follows: A servo rib expanding machine, in which a conveying chain straddles the middle of the upper surface of the machine base, and a barrel with a horizontal axis is transmitted on the conveying chain; on the left and right sides of the barrel sleeve, machine boxes are symmetrically arranged, and the lower surface of the machine box is slidably connected to the upper surface of the machine base through linear guide rails; on both sides of the machine base, servo motors I are respectively provided, and the servo motor I is connected to a crank through a speed reducer I. One end of the crank is hinged to one end of a connecting rod, and the other end of the connecting rod is connected to the bottom of the corresponding machine box through a spherical plain bearing; an eccentric mechanism is respectively arranged in each machine box; a push rod is slidably fitted in the box body through a guide sleeve. One end of the push rod is fixedly connected to an expanding head, and the position of the expanding head corresponds to the end position of the barrel sleeve. The other end of the push rod passes through the guide sleeve and is hinged to the eccentric mechanism.

[0005] The eccentric mechanism includes a servo motor II, a speed reducer II, an eccentric wheel and an eccentric sleeve; the servo motor II is connected to the rotating shaft of the eccentric wheel through the speed reducer II, an eccentric sleeve is provided on the eccentric wheel, and one end of the eccentric sleeve is hinged to the push rod.

[0006] A lifting cylinder is arranged in the middle of the machine base. The piston top of the lifting cylinder extends out of the machine base and is located at the middle position of the conveying chain, and contacts the middle part of the barrel sleeve after lifting.

[0007] The servo rib expanding machine of the present application uses a servo motor I and a connecting rod mechanism to drive the overall movement of the machine box, and then uses a servo motor II to drive the movement of the expanding head for rib expanding work. The overall operation is stable and the rib expanding effect is good. At the same time, due to the use of servo drive, the manufacturing cost is saved and the service life of the overall equipment is improved. Brief Description of the Drawings

[0010] As Figure 1 and Figure 2 shown, a servo rib expanding machine has a conveying chain 6 spanning across the middle of the upper surface of the machine base 1 horizontally, and a barrel sleeve 7 with a horizontal axis is transmitted on the conveying chain 6; machine boxes 2 are symmetrically arranged on the left and right sides of the barrel sleeve 7, and the lower surface of the machine box 2 is slidably connected to the upper surface of the machine base 1 through linear guide rails 14; servo motors I 8 are respectively arranged on both sides of the machine base 1, the servo motors I 8 are connected to cranks 10 through speed reducers I 9, one end of a crank 10 is hinged to one end of a connecting rod 11, and the other end of the connecting rod 11 is connected to the bottom of the corresponding machine box 2 through a spherical plain bearing 12; an eccentric mechanism is respectively arranged in each machine box 2; a push rod 4 is slidably fitted in the machine box 2 through a guide sleeve 3, one end of the push rod 4 is fixedly connected to a rib expanding head 5, the position of the rib expanding head 5 corresponds to the end position of the barrel sleeve 7, and the other end of the push rod 4 passes through the guide sleeve 3 and is hinged and fitted with the eccentric mechanism.

[0011] The said eccentric mechanism includes a servo motor II 15, a speed reducer II 16, an eccentric wheel 13 and an eccentric sleeve 18; the servo motor II 15 is connected to the rotating shaft of the eccentric wheel 13 through the speed reducer II 16, an eccentric sleeve 18 is arranged on the eccentric wheel 13, and one end of the eccentric sleeve 18 is hinged to the push rod 4.

[0012] A lifting cylinder 19 is arranged in the middle of the machine base 1, the piston top of the lifting cylinder 19 extends out of the machine base 1 and is located at the middle position of the conveying chain 6, and contacts the middle part of the barrel sleeve 7 after jacking up. When the lifting cylinder 19 is started to jack up, the barrel sleeve 7 can be jacked up to the processing position.

[0013] The working process of the servo rib expanding machine is as follows: First, start the lifting cylinder 19 to jack up the barrel sleeve 7 to the processing position, then start the servo motor I 8 to rotate a certain angle, drive the machine box 2 to move on the linear guide rail 14 through the crank 10, the connecting rod 11 and the spherical plain bearing 12, so that the rib expanding head 5 contacts the inner walls on both sides of the barrel sleeve 7. Then start the servo motor II 15 to rotate a certain angle, make the eccentric wheel 13 rotate eccentrically, the eccentric sleeve 18 is equivalent to a connecting rod mechanism, drive the push rod 4 to move linearly in the guide sleeve 3, so a tightening force towards the barrel sleeve 7 is generated, and the rib is processed. After the rib expanding is completed, the rib expanding head 5 retracts, the machine box 2 withdraws, and the lifting cylinder 19 descends, so that the barrel sleeve 7 falls back onto the conveying chain 6 and is ready to be transferred to the next process.
