Description

Technical Field

[0001] The utility model relates to the technical field of tricycle production, in particular to a processing device for a front bumper. Background Technique

[0002] Tricycles are relatively common means of transportation at present, which can carry people or goods. Usually, a front bumper is installed at the front of the tricycle to absorb and slow down the external impact force and protect the safety of the front part of the vehicle body. The current front bumpers are mainly made by processing round tubes. During the production process, the round tubes need to be cut and blanked according to certain length specifications, and then bent and welded. However, when cutting and blanking the round tubes at present, the cutting and feeding of the round tubes operate separately. The round tubes need to be placed at the cutting length position before cutting, and the overall cutting action cannot run continuously, resulting in low cutting efficiency and affecting the production efficiency.

A feeding mechanism 2 is connected to the lower side of the cutting mechanism 3. Clamping assemblies for fixedly limiting the round tube are arranged on both sides of the cutting mechanism 3 on the support mechanism 1, and a limiting mechanism for limiting and adjusting the cutting length of the round tube is arranged on the support mechanism 1;

[0027] In this embodiment: The feeding mechanism 2 includes a support frame 21 arranged under the support roller 12. A feeding roller 22 is arranged on the support frame 21. The feeding roller 22 is located between adjacent support rollers 12. One end of the feeding roller 22 is connected to a first motor 23 for providing the rotational power of the feeding roller 22. A support rod 25 is installed at the rear end of the support frame 21. A connecting rod 26 is connected to the support rod 25. A sliding seat 27 is arranged on the support frame 21; A sliding groove slidably matched with the sliding seat 27 is formed on the outer wall of the frame body 11. There are two feeding rollers 22. The feeding rollers 22 are rotatably connected to the support frame 21. A transmission member 24 is arranged at the other end of the feeding roller 22. The transmission member 24 is a sprocket, and a chain is sleeved on the outer diameter of the sprocket. The outer surface of the feeding roller 22 is provided with raised lines to improve the pushing force of the feeding roller 22 on the round tube. The connecting rod 26 is rotatably connected to the support rod 25. The outer diameter of the feeding roller 22 is slightly larger than the outer diameter of the support roller 12. By driving the feeding roller 22 to rotate through the first motor 23, the round tube is pushed to one side, facilitating the feeding of the round tube.

[0028] In this embodiment: The cutting mechanism 3 includes a column 31 fixed to the upper end of the frame body 11. A rotating beam 32 is arranged at a lower position of the column 31. A hydraulic cylinder 33 is arranged between the rotating beam 32 and the column 31. A cutting disc 35 is installed on the rotating beam 32 through a rotating shaft. A second motor 34 for driving the cutting disc 35 to rotate is installed on the rotating beam 32; The connecting rod 26 is rotatably connected to the rotating beam 32. The rotating beam 32 is rotatably connected to the column 31. Both ends of the hydraulic cylinder 33 are respectively rotatably connected to the column 31 and the rotating beam 32. By driving the cutting disc 35 to rotate through the operation of the second motor 34, when cutting is required, the hydraulic cylinder 33 extends to push the rotating beam 32 to rotate downward, so that the cutting disc 35 cuts the fixed round tube.

[0029] In this embodiment: The clamping assembly includes cylinders 41 fixed to the frame body 11. The cylinders 41 are arranged opposite to each other front and back. The cylinders 41 are respectively arranged on both sides of the cutting mechanism 3. Clamping plates 42 are fixed to the opposite ends of the cylinders 41. After the round tube moves into place, the cylinders 41 extend to push the clamping plates 42 to move relatively, clamping and limiting the round tube on both sides of the cutting position.

[0030] In this embodiment: The limit mechanism includes an adjustment screw rod 51 arranged on the frame body 11. A baffle plate 52 parallel to the feeding roller 22 is arranged on the adjustment screw rod 51. Infrared limit switches 53 are arranged opposite to each other before and after on the baffle plate 52 near one side of the cutting disc 35. The baffle plate 52 is slidably connected to the adjustment screw rod 51. Nuts are arranged on both sides of the baffle plate 52 on the adjustment screw rod 51. By rotating and adjusting the nuts on the adjustment screw rod 51, the horizontal distance between the baffle plate 52 and the cutting disc 35 changes. When the round tube moves through the feeding mechanism 2 and contacts the baffle plate 52, the infrared rays between the infrared limit switches 53 are blocked, and the signal is fed back to the control system, controlling the cylinder 41 to extend to clamp and fix the round tube, and the hydraulic cylinder 33 extends to push the rotating beam 32 to rotate downward. This control system is a commonly used electrical signal feedback system, which is prior art and will not be elaborated here again.

The round tube is placed on the support roller 12 and the feeding roller 22. The first motor 23 is started to drive the feeding roller 22 to rotate, and the round tube is pushed towards the baffle plate 52. After the round tube contacts the baffle plate 52, the cylinder 41 extends to push the clamping plate 42 to move relatively, clamping and fixing the round tube. The hydraulic cylinder 33 extends to drive the rotating beam 32 to rotate downward. The connecting rod 26 on the lower side of the rotating beam 32 pushes the support rod 25 and the support frame 21 as a whole to move downward under the limit of the sliding seat 27, separating the rotating feeding roller 22 from the round tube. The cutting disc 35 driven by the second motor 34 is moved downward to cut the round tube. Until the round tube is cut off, the cylinder 41 contracts, the clamping plate 42 releases the round tube, the cut-off round tube is taken off, the hydraulic cylinder 33 contracts, driving the rotating beam 32 to rotate upward, and at the same time driving the support frame 21 as a whole to move upward, and pushing the round tube towards the baffle plate 52 again.
