Fixing device of cutting die of upper working table of die cutting machine

Abstract

The invention discloses a fixing device of a cutting die of an upper working table of a die cutting machine. Four screws are divided into two groups, wherein each group of screws is respectively provided with a screw with left screw threads and a screw with right screw threads; the two groups of screws are respectively arranged at the lower parts of the front side surface and the back side surface of the upper working table through screw seats; the right ends of the two screws positioned on the left sides of the front side and the back side of the upper working table as well as the left ends of the two screws positioned on the right sides of the front side and the back side of the upper working table are respectively fixed on the left ends and the right ends of two worm wheels; a transmission shaft is mounted at the centers of the lower parts of the front side surface and the back side surface of the upper working table in a penetrating manner; two worms are respectively arranged on the two ends of the transmission shaft; the two worms are respectively meshed with the two worm wheels; four chuck fixing seats are respectively sleeved on the four screws; two chucks are respectively positioned on the left side and the right side below the upper working table; the two ends of the chucks are respectively arranged on the bottoms of the chuck fixing seats positioned on the left sidesand the right sides of the front and the back side surfaces of the upper working table; and a synchronous belt wheel is arranged on the transmission shaft and is connected with a synchronous belt wheel on a hand wheel shaft arranged on the front side surface of the upper working table through a synchronous belt.

Description

technical field [0001] The invention relates to a die-cutting device for an upper workbench of a die-cutting machine. Background technique [0002] The blanking of existing non-metallic materials is usually done by equipment such as die-cutting machines. The existing die-cutting machine contains an upper workbench and a lower workbench, the lower workbench is arranged on the guide rail of the frame, and the bottom of the upper workbench is equipped with a cutting die. When working, the materials are stacked on the lower workbench, and the lower workbench moves from outside to inside along the guide rail to the set position and then stops. The knife die moves back to the original position, and the lower table moves out along the guide rail to the original position and then stops, ready for the next operation. In the prior art, the cutting dies are usually arranged on the bottom of the upper workbench by bolts. Therefore, when replacing different cutting dies for different v...

Problems solved by technology

In the prior art, die dies are usually set on the bottom of the upper workbench by bolts, so when changing different die dies for different varieties, it is not only troublesome, but also the work efficiency of changing die dies is low
