Description

Technical Field

[0001] The invention relates to the technical field of wheel rim manufacturing, in particular to a welding and forming device for a section steel wheel rim. Background Art

[0002] The wheel rim is an important component of the wheel. It refers to the circular metal frame on the inside of the tire. Its main function is to support the tire and fix the tire on the vehicle's axle hub. The rim not only affects the safety and stability of the vehicle's driving, but also has a direct impact on the appearance of the car. The rim is usually made of steel, aluminum alloy or magnesium alloy.

[0003] Steel wheel rims are the most common. Generally, steel wheel rims are composed of two parts, one is the steel cylinder and the other is the inner frame. The steel cylinder is made of steel plates rolled by a winding machine. After rolling, the butt joints of the steel cylinder need to be further welded to ensure the integrity of the steel cylinder.

[0004] The existing wheel hub steel cylinder welding equipment is a conventional welding machine, which only has the function of welding the steel cylinder butt joint. Generally, when the steel cylinder is wound and transported, it is necessary to manually assist the steel cylinder to rotate and align the welding seam to the welding line position of the welding machine. The wheel hub steel cylinder is relatively heavy, and it is troublesome for the staff to rotate it. Moreover, the staff mostly rely on visual inspection to check whether it is aligned. The alignment process is time-consuming and the work efficiency needs to be improved. At the same time, since the steel cylinder will have a certain resilience after being rolled, this will cause the butt joint to have different widths. The wheel hub is a high-precision product, and smaller size differences will affect the subsequent installation, which is not conducive to ensuring the high-precision production of the wheel hub. In addition, the steel cylinder welding is mostly done after one side is welded, and then the next side is welded. The work efficiency needs to be further improved. Summary of the invention

[0036] During specific operation, the motor 2 321 controls the screw rod 2 322 to drive the mobile mounting frame 37 to rise and fall along the guide rod 2 323. When the steel cylinder enters the fixed mounting frame 36 and is supported by the two clamping rollers 31 on the lower side, the mobile mounting frame 37 moves down to make the two clamping rollers 31 on the upper side clamp the upper part of the steel cylinder. The four groups of clamping rollers 31 clamp the steel cylinder in an array to ensure that the connecting seams of the steel cylinder are in close contact. After the mobile mounting frame 37 moves up to loosen the welded steel cylinder, the electric push rod 1 3242 controls the lifting roller 3241 to lift it up at the lower front position of the steel cylinder. The force on the steel cylinder will use the clamping roller 31 at the lower rear position as the fulcrum and rotate to the outside of the locking mechanism 3.

[0037] See also Figure 1 , Figure 4 and Figure 6 The rolling assembly 33 includes a first bevel gear 333 fixedly connected to the left end of each rotating rod, and each first bevel gear 333 is meshed with a second bevel gear 334 at the lower side.

The four groups of clamping rollers 31 rotate synchronously and in the same direction. When the four groups of clamping rollers 31 are pressed against the steel cylinder at the same time, the steel cylinder is controlled to rotate by four-point friction to change the position of the welding seam of the steel cylinder.

[0039] See also Figure 5 The front end of the right side wall of the arch frame 35 is fixedly connected with a support bar 336 at a position corresponding to the central axis of the steel cylinder in the locked state, and the front end of the support bar 336 is fixedly connected with an information sensor 337 at a position corresponding to the cylinder wall of the steel cylinder in the locked state.

[0040] During specific operation, the welding seam of the steel cylinder is sensed by the ultrasonic sensor. The ultrasonic sensor can sense the steel cylinder for a long time under normal conditions. When the welding seam of the steel cylinder rotates to the sensing line of the ultrasonic sensor, the welding seam is in a discharge state. The information feedback of the ultrasonic sensor is different from that of the normal state. The information of this state is transmitted to the controller, and the controller controls the motor three 331 to stop running, so that the welding seam of the steel cylinder is in the specified position.

[0041] See also Figure 1 , Figure 5 and Figure 6 The welding assembly 34 includes a side mounting frame 341 fixedly connected to the left side of the arch frame 35, the side mounting frame 341 is bent toward the front side and fixedly connected to an electric push rod 342, the output end of the electric push rod 342 faces the right side and is fixedly connected to a U-shaped frame 343, the distance between the two symmetrical walls of the U-shaped frame 343 is much larger than the thickness of the steel cylinder wall, the position of the U-shaped frame 343 also corresponds to the direction line pointed by the information sensor 337, the right ends of the two walls of the U-shaped frame 343 are fixedly connected to laser welding gun heads 344, and the output muzzles of the two laser welding gun heads 344 are relatively distributed.

[0043] When in use: S1: first, arrange the rolled steel cylinders in order in the feeding trough frame 22, and control the rotation of the screw rod 213 through the motor 214, and the screw rod 213 drives the partition plate 211 to rise and fall in the hole, when the upper end of the partition plate 211 is flush with the bottom wall of the feeding trough frame 22, there is no obstacle inside the feeding trough frame 22, and the steel cylinders will be automatically pushed forward by gravity. The partition plate 211 on the front side is a control plate for intermittent feeding, which can release the steel cylinders on the front side, and the partition plate 211 on the rear side is a limit plate, which can control the subsequent The steel cylinder is conveyed and limited, and the two groups of partition plates 211 operate independently. When discharging, the front partition plate 211 is controlled to drop to the bottom wall of the material trough frame 22. After the discharging is completed, the front partition plate 211 is raised, and then the rear partition plate 211 is controlled to drop to the bottom wall of the material trough frame 22. The subsequent steel cylinders will move to the front partition plate 211 without any obstacles. After the frontmost steel cylinder moves to the position of the front partition plate 211, the rear partition plate 211 is raised again to separate the frontmost steel cylinder between the two groups of partition plates 211.

[0044] S2: The steel cylinder slid by the sliding frame 23 will roll onto the two pressing rollers 31 on the lower side, and then, the motor 2 321 controls the screw rod 2 322 to drive the movable mounting frame 37 to move downward along the guide rod 2 323, and the movable mounting frame 37 moves downward so that the two pressing rollers 31 on the upper side press the upper part of the steel cylinder, and the four groups of pressing rollers 31 press the steel cylinder in an array manner, and then the motor 331 controls the connected limiting shaft 332 to rotate, and the synchronous belt 335 drives another limiting shaft 332 to rotate synchronously, and the limiting shaft 332 drives the first bevel gear 333 to rotate, and the first bevel gear 333 drives the second bevel gear 334 to rotate and control the connected pressing rollers 31 to rotate, and the four groups of pressing rollers 31 rotate synchronously and in the same direction. When the four groups of pressing rollers 31 are in close contact with the steel cylinder at the same time, the steel cylinder is controlled to rotate by the four-point friction force to change the position of the steel cylinder welding seam.

[0045] S3: Then the ultrasonic sensor is used to sense the weld of the steel cylinder. The ultrasonic sensor can sense the steel cylinder for a long time under normal conditions. When the weld of the steel cylinder rotates to the sensing line of the ultrasonic sensor, the weld is in a discharge state. The information feedback of the ultrasonic sensor is different from the normal state. The information of this state is transmitted to the controller, and the controller controls the motor 331 to stop running, so that the weld of the steel cylinder is in a specified position.

After the welding is completed, the welded steel cylinder is moved up and released by the mobile mounting frame 37, and then the electric push rod 1 3242 controls the lifting roller 3241 to lift it at the lower front position of the steel cylinder. The steel cylinder is subjected to force and uses the clamping roller 31 at the lower rear position as a fulcrum to rotate and disengage from the locking mechanism 3, and then the above steps are continued to weld the next steel cylinder.
