Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: a roll forming device for a reinforcing edge of a silencing drum is shown in figures 1-3 and comprises a base platform 1, wherein a support 2 is arranged on the base platform 1, and the support 2 is rotatably connected with a driving shaft 4 through a bearing I3; one end of the driving shaft 4 is connected with a driving motor 5, the other end of the driving shaft is coaxially connected with a supporting roller 6, convex prismatic platforms 7 are axially distributed on the outer circular surface of the supporting roller 6, and limiting plates 8 are further arranged at two ends of the supporting roller 6; a press roller 9 is arranged above the supporting roller 6, concave ridge grooves 10 are axially distributed on the outer circular surface of the press roller 9, and the concave ridge grooves 10 are in one-to-one correspondence with the ridge platforms 7 in the vertical direction; one end of the compression roller 9 penetrates through the avoiding groove 11 formed in the support 2 and is rotatably connected with the movable seat 13 through the bearing II 12, and the top end of the movable seat 13 is connected with a hydraulic cylinder 14 fixedly arranged at the top of the support 2.
When the reinforcing edge is processed, the welded cylinder 17 is sleeved on the supporting roller 6, and the two ends are axially limited by the limiting plates 8; the driving motor 5 is started to drive the supporting roller 6 to rotate through the driving shaft 4; the hydraulic cylinder 14 drives the movable seat 13 to move downwards, and the press roller 9 moves downwards along with the movable seat until the press roller 9 presses the surface of the cylinder 17, so that the concave ridge groove 10 and the ridge table 7 jointly act to form a bulge; at the moment, under the driving of the supporting roller 6, the pressing roller 9 rotates in the opposite direction to do driven motion, so that the opposite rolling of the supporting roller 6 and the pressing roller 9 is formed, and continuous protrusions are formed on the surface of the cylinder 17 through the opposite rolling; when the cylinder 17 is rolled by the counter-roller for one turn, a reinforcing rib consisting of continuous protrusions is formed on the surface of the cylinder 17.
