A guide device for a double toggle punch press

Abstract

The invention discloses a double-toggle-rod punch guiding device which comprises a movable table top, a guiding block for guiding, a fixing shaft and a pair of driving mechanisms. A guiding groove is formed in the center of the movable table top. The guiding block is arranged in the guiding groove in a sleeved mode. A circular hole is formed in the center of the guiding block. The fixing shaft penetrates through the circular hole of the guiding block. The two ends of the fixing shaft are fixed on a punch support. The pair of driving mechanism is hinged to the upper end of the movable table top and is arranged symmetrically relative to the guiding groove. The driving mechanisms are connected to the upper end of the movable table top, when the driving mechanisms drive the movable table top to move up and down, the movable table top moves up and down along the guiding block under the effect of the guiding groove and can swing around the fixing shaft, the center of the movable table top is corrected automatically, and under the common effect of a fixed table top and the movable table top, the purpose of workpiece stamping is achieved.

Description

【Technical field】 [0001] The invention relates to a guiding device, in particular to a guiding device for a double toggle punch press. 【Background technique】 [0002] The function of the punch press is to stamp the metal sheet. At present, most of the punch presses use the combination of the double toggle mechanism and the crank linkage mechanism to drive the upper and lower reciprocating movements of the movable table to punch the metal sheet. CN201210044752.9, the disadvantage of this kind of guiding device that uses the outer surface of the movable table as the guide surface, and the fixed guide surface is located outside the movable guide surface is that the area of ​​the movable table is limited by the fixed guide surface. If it is necessary to increase the movable table If the area is large, the area of ​​the fixed guide surface must be increased first, which will complicate the manufacturing process of the machine, increase the manufacturing cost, and deteriorate the...

At present, most of the punch presses use the combination of the double toggle mechanism and the crank linkage mechanism to drive the upper and lower reciprocating movements of the movable table to punch the metal sheet. CN201210044752.9, the disadvantage of this kind of guiding device that uses the outer surface of the movable table as the guide surface, and the fixed guide surface is located outside the movable guide surface is that the area of ​​the movable table is limited by the fixed guide surface. If it is necessary to increase the movable table If the area is larger, the area of ​​the fixed guide surface must be increased first, which will complicate the manufacturing process of the machine, increase the manufacturing cost, and deteriorate the reliability of the machine.
