Claims

[Claims for Utility Model Registration] (1) Two crankshafts arranged in parallel rotate in opposite directions, and two
In a four-point press machine, a slide is connected to a total of four eccentric parts via connecting rods, and the main gear, to which the rotational force of the pinion gear installed on the drive shaft is transmitted, and the eccentric part of this main gear can be freely rotated. At least one eccentric link mechanism is provided that includes a sub-crankshaft provided and a link connecting an eccentric portion of the sub-crankshaft to a body of the main gear, and the sub-crank of the eccentric link mechanism A drive device for a four-point press machine, characterized in that at least one of the first and second main crankshafts constituting the two crankshafts is coaxially connected to the shaft. (2) In paragraph 1 of the claims for utility model registration,
The eccentric link mechanism has two links arranged symmetrically, the main gears of these eccentric link mechanisms mesh and rotate in opposite directions, and the first and second main crankshafts are divided into two. A drive device for a four-point press machine, characterized in that the split shaft is connected to both ends of the sub-crankshafts of the two eccentric link mechanisms. (3) In paragraph 1 of the claims for utility model registration,
The eccentric link mechanism has two links arranged symmetrically, and the main gears of these eccentric link mechanisms mesh with each other and rotate in opposite directions, and one end of the sub-crankshaft of these eccentric link mechanisms A drive device for a four-point press machine, characterized in that first and second main crankshafts are connected to the drive device. (4) In paragraph 1 of the claims for utility model registration,
The number of the eccentric link mechanisms is one, and the first main crankshaft is composed of two divided shafts, and the divided shafts are connected to both ends of the sub-crankshaft of the eccentric link mechanism. A drive device for a four-point press machine, characterized in that a second main crankshaft is connected to one side of the drive device via a constant speed reversing gear. (5) In paragraph 1 of the claims for utility model registration,
The eccentric link mechanism is one piece, and the first and second main crankshafts are composed of two divided shafts,
A split shaft of a first main crankshaft is connected to both ends of the sub-crankshaft of the eccentric link mechanism, and a split shaft of a second main crankshaft is connected to each of these split shafts via a constant velocity reversing gear. A drive device for a four-point press machine, which is characterized by:
