Description

Technical Field

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

[0002] Rolling corrugations on steel drums is one of the process steps in steel drum manufacturing. This process uses a corrugating machine for processing, which makes the steel drum produce a W-rib structure. The W-rib structure can greatly enhance the strength of the steel drum without changing the material thickness, making the steel drum more resistant to impact and not easily deformed during transportation. In addition, the outer diameter of the ring rib of the W-ring rib structure is smaller than the outer diameter after the top and bottom of the drum are curled, so that only the curled parts of the drums contact each other during transportation, eliminating the friction between the ring ribs, thus maximizing the improvement of the defects that the large ribs of national standard steel drums are worn out and the drum body is easily deformed during transportation.

[0003] However, the reciprocating motion of the chassis of the existing steel drum corrugating machine is driven by a hydraulic cylinder, which not only occupies a large volume and is heavy, but also has a high cost. Moreover, the precision of the reciprocating motion is low. At the same time, after the hydraulic circuit is used for a period of time, problems such as oil leakage are likely to occur, and later maintenance is difficult. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a servo corrugating machine. The servo motor drives the chassis to move forward and backward rhythmically through a connecting rod mechanism, with low manufacturing cost, high transmission precision, and being conducive to maintenance.

[0005] To solve the above problems, the specific technical solution of the utility model is as follows: A servo corrugating machine, in which a conveying chain straddles the middle of the upper surface of the machine base, and the barrel is sleeved on the conveying chain for transmission; on both sides of the barrel sleeve, chassis are symmetrically arranged, and the lower surface of the chassis is slidably connected to the upper surface of the machine base through linear guide rails; a servo motor is arranged at the bottom of the machine base, the servo motor is connected to a crank through a speed reducer, 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 chassis through a spherical plain bearing; on each chassis, there is a corrugating roller motor, and the corrugating roller motor is respectively connected to a fixed roller and a moving roller through a transmission device; the rotating shaft of the moving roller is connected to a vertical feeding device on the chassis; the fixed roller contacts the outer circumference of the barrel sleeve, the moving roller contacts the inner circumference of the barrel sleeve through the vertical feeding device, and the fixed roller and the moving roller are arranged parallel to each other up and down, clamping the barrel sleeve and rotating to roll out corrugations.

[0006] The vertical feeding device includes a lifting motor, a cam and a roller device; the lifting motor shaft of the lifting motor is connected to the cam; on the side wall of the chassis, there is a vertical guide rail, on which a slider is slidably connected, the slider contacts the rotating shaft of the moving roller, and a roller frame is connected to the lower surface of the slider, and the roller on the roller frame contacts and cooperates with the cam.

[0007] The roller frame and the slider are connected through an adjusting lead screw.

[0008] The servo corrugating machine of the present application adopts the above structure and has the following advantages:

[0009] 1) The horizontal movement of the chassis is driven by a servo motor connected to a crank - connecting rod structure, which not only has the advantage of sensitive response but also is convenient for debugging;

[0010] 2) The vertical feeding device adopts a cam structure. The rotation of the cam is converted into the vertical movement of the moving roller, so as to realize the clamping action on the barrel sleeve, and the circumferential movement of the barrel sleeve completes the corrugated bulging work. Description of the Drawings

[0011] Figure 1 It is the front view of the servo corrugating machine.

[0012] Figure 2 It is Figure 1 the A - A cross - sectional view of Detailed Implementation Modes

[0013] As Figure 1 and Figure 2 shown, a servo corrugating machine has a conveying chain 4 straddling the middle of the upper surface of the machine base 1, and the barrel sleeve 5 is transported on the conveying chain 4; on both sides of the barrel sleeve 5, chassis 2 are symmetrically arranged. The lower surface of the chassis 2 is slidably connected to the upper surface of the machine base 1 through linear guide rails 9; at the bottom of the machine base 1, there is a servo motor 11. The servo motor 11 is connected to a crank 13 through a speed reducer 12. One end of the crank 13 is hinged to one end of a connecting rod 14, and the other end of the connecting rod 14 is connected to the bottom of the chassis 2 through a spherical plain bearing 15; on each chassis 2, there is a corrugated roller motor 6. The corrugated roller motor 6 is respectively connected to a fixed roller 3 and a moving roller 8 through a transmission device 7; the rotating shaft of the moving roller 8 is connected to the vertical feeding device on the chassis 2; the fixed roller 3 contacts the outer circumference of the barrel sleeve 5, and the moving roller 8 contacts the inner circumference of the barrel sleeve 5 through the vertical feeding device, and the fixed roller 3 and the moving roller 8 are arranged parallel to each other up and down, clamping the barrel sleeve 5 and rotating to roll out the corrugations. The feeding action of the chassis 2 along the linear guide rails 9 is driven by the servo motor 11, which can not only adjust the feeding rhythm but also improve the movement accuracy of the chassis 2 through the connection and drive of the crank and the connecting rod. At the same time, its structure is convenient for later maintenance.

[0014] The vertical feeding device includes a lifting motor 21, a cam 23 and a roller device 24; the lifting motor shaft 22 of the lifting motor 21 is connected to the cam 23; on the side wall of the chassis 2, there is a vertical guide rail 25, on which a slider 26 is slidably connected. The slider 26 contacts the rotating shaft of the moving roller 8, and a roller frame 24 is connected to the lower surface of the slider 26. The rollers on the roller frame 24 are in contact and cooperation with the cam 23. After starting the lifting motor 21, the cam 23 rotates a certain angle, thus completing the lifting action of the moving roller 8. At the same time, according to different barrel sleeve thicknesses and corrugation heights, different rising heights can be selected, that is, by calculating the deflection radius corresponding to the rotation angle of the cam 23.

[0015] To achieve the height precision adjustment of the moving roller 8, an adjusting lead screw 27 is connected between the roller stand 24 and the slider 26.

[0016] The working process of the servo corrugating machine of this application is as follows: When the barrel sleeve 5 is sent to the designated position by the conveying chain 4, then the servo motors 11 on both sides are started simultaneously. The rotation of the servo motors 11 drives the movement of the crank 13, the connecting rod 14 and the spherical plain bearing 15, driving the machine box 2 to move on the linear guide 9, and making the opened fixed roller 3 and the moving roller 8 move towards the barrel sleeve 5; When the axial movement of the fixed roller 3 and the moving roller 8 is completed, the lifting motor 21 is started, and the cam 23 rotates by an angle. The slider 26 drives the moving roller 8 to lift upward along the vertical guide 25 to clamp the barrel sleeve 5; Finally, the corrugating roller motor 6 is started, and the fixed roller 3 and the moving roller 8 are driven to rotate simultaneously through the transmission device 7, so that the barrel sleeve 5 forms corrugated rolling ribs during the rotation process. After the rolling ribs are completed, all actions operate in reverse to complete the detachment of the barrel sleeve and complete a processing cycle.
