A pressing machine for joining two workpieces includes a workbench (10), a rigging (30) providing periodical vertical movement, a pair of pressing devices (42) for impacting the workpieces, and a push apparatus (70). A wedge block (40) is secured under the rigging. The wedge block has two first slopes (48). The push apparatus includes a push block (70) with a second slope. A stop screw (26) is secured in the workbench. When the rigging is moved downwardly, the pressing devices impact the workpieces and the first slopes abut against the second slope. The push block is moved toward the workpieces, thereby pushing one workpiece to move relative to the other one. When the wedge block abuts the stop screw, the push block stops pushing the workpiece. The moving workpiece is completely engaged with hooks formed in the stationary workpiece at corresponding openings defined in the moving workpiece.
