The top of the upper pressing seat 11 is connected to the hydraulic rod of the hydraulic cylinder 13, and the lower pressing seat 12 corresponds to the bottom of the upper pressing seat 11. The operating table 2 is composed of two groups of rolling pressing wheels 21, and the two groups of rolling pressing wheels 21 are respectively installed in the upper pressing seat 11 and the lower pressing seat 12. The pushing seat 4 is arranged below the lower group of rolling pressing wheels 21, and the pushing seat 4 is provided with an optical axis 41 and an automatic circuit breaker 42. The automatic circuit breaker 42 is movably installed at the side end of the optical axis 41. The reducer 5 is arranged on the rear side of the operating table 2, the driving seat 6 is connected with the reducer 5, and the control box 7 is installed on the top of the pressing mechanism 1. The upper press seat 11 is driven by the hydraulic rod of the hydraulic cylinder 13 to move downward and close to the lower press seat 12, and the cross bar is placed on the lower rolling press wheel 21. The cross bar is driven to move by the rotation of the upper and lower rolling press wheels 21.

[0027] In one embodiment, the hydraulic pump 3 is provided with a heat dissipation fan 31, which is installed on the side of the hydraulic pump 3 through a bracket and connected to the hydraulic pump 3 through a pipeline.

[0028] In one embodiment, the reducer 5 and the drive seat 6 are both provided with two groups, and a drive shaft 61 is provided on one side of the drive seat 6. The drive shaft 61 is connected to the rolling pressure wheel 21 correspondingly at the upper and lower sides, and the rotation trajectories of the upper and lower drive shafts 61 are opposite. The reducer 5 drives the internal gear of the drive seat 6 to rotate, and the drive shaft 61 is connected to the rolling pressure wheel 21, thereby realizing the operation of the rolling pressure wheel 21. The crossbar is placed on the lower rolling pressure wheel 21, and the crossbar is driven to move through the rotation of the upper and lower rolling pressure wheels 21. The principle is the same as that of the centerless grinder, so it is not explained here.

[0029] In one embodiment, a gear set is disposed in the driving seat 6, and the gear set is connected to the driving shaft 61. The coordinated rotation of the gear set realizes the rotation of the driving shaft 61, and drives the rolling pressure wheel 21 to rotate.
