Problems solved by technology
The worm gear transmission mechanism has the advantages of high transmission precision, but it also has the following disadvantages: after a long time of use, the meshing teeth of the worm wheel and the worm will inevitably wear out, causing gaps between the teeth, which will lead to transmission errors and affect the impact. Hole machining accuracy, and will damage the punch
However, the above-mentioned structure is very complicated, and it is also very inconvenient to adjust.
In addition, the above-mentioned split worm gear structure also requires a series of complicated steps to complete the neutral adjustment of the autorotation mold.

Embodiment Construction
[0037] In conjunction with the accompanying drawings, a dual-lead worm transmission mechanism for the rotation mold of a CNC turret punch press includes a bed 1, an upper turntable 2 and a lower turntable 3 are arranged on the bed 1, and a Several fixed molds 4 and two rotation molds. For the convenience of description, the two autorotation molds are respectively defined as the first autorotation mold 5 and the second autorotation mold 6, and the first autorotation mold 5 and the second autorotation mold 6 are arranged at an angle of 180 degrees on the turntable. The first autorotation mold 5 and the transmission part that drives its operation are described first below, and the structure of the second autorotation mold 6 and the transmission part that drives its operation are the same as the first autorotation mold 5 .
[0038] The first autorotation mold 5 includes a corresponding upper autorotation mold 501 and a lower autorotation mold 502 . Such as Figure 1-4 As shown, ...

The invention discloses a rotary die double-lead worm transmission mechanism for a numerical control turret punch press. The rotary die double-lead worm transmission mechanism comprises an upper double-lead worm, an upper worm wheel, a lower double-lead worm and a lower worm wheel. One end of the upper double-lead worm is connected with an upper transmission shaft, the other end of the upper double-lead worm is meshed with the upper worm wheel, the upper worm wheel is connected with an upper rotary die, and the upper rotary die is provided with a punch and installed on an upper turnplate. One end of the lower double-lead worm is connected with a lower transmission shaft, the other end of the lower double-lead worm is meshed with the lower worm wheel, the lower worm wheel is connected with a lower rotary die, the lower rotary die is provided with a female die matched with the punch and is installed on a lower turnplate, and the upper transmission shaft and the lower transmission shaft are driven by a first servo motor to run through a synchronous belt. Due to the fact that the tooth thickness of each double-lead worm varies, after gaps occur between the worm wheels and teeth of the double-lead worms, the worm wheels can be in gapless meshing with the double-lead worms again by adjusting the axial position of the double-lead worms, and the operation is simple and convenient.
Description
technical field [0001] The invention belongs to the technical field of machine tool equipment, and in particular relates to a double-lead worm drive mechanism of a CNC turret punch press autorotation die. Background technique [0002] CNC punching machine is a kind of industrial processing equipment for punching and shallow drawing on the plate. It uses software programming to carry out the processing program, and sends the plate to the processing station through the feeding mechanism. At the same time, through the system in the mold library Select the appropriate processing mold, and then punch through the power system according to the programming program to complete the processing of the plate. The stamping die in the CNC turret punching machine is placed on the turntable, and the turntable is driven to rotate by the sprocket. When the turntable rotates to the corresponding stamping station, the punch of the machine tool hits the stamping die to complete the stamping actio...
