Full-automatic multistation notching machine

Abstract

The invention relates to a full-automatic multistation notching machine with simple operation and high production efficiency, comprising a storing and conveying mechanism, a transmitting and guiding system and a cutting system, wherein the storing and conveying system comprises a rotating box; a spirally-lifting transporting belt is connected to the inner side wall of the rotating box, and the terminal of the transporting belt is connected with a conveying belt; the conveying belt belongs to the transmitting and guiding system; a notch box is arranged at the other end of the conveying belt; a transfer box is connected in the notch box; a notch fixing seat is arranged in the transfer box; a push-out cylinder, a notch die and a shell core are arranged on the notch fixing seat; the push-out cylinder and the notch die correspond to the shell core up and down; a transmission shaft fixing seat is also arranged in the transfer box and below the notch fixing seat; a transmission shaft and a push-out rod are arranged on the transmission shaft fixing seat; the transmission shaft corresponds to the push-out rod up and down; a pallet is connected in the notch box; a cylinder is fixedly arranged on the pallet; the front end of a telescopic rod of the cylinder is connected with a push-out rod fixing plate; and a push rod is arranged on the push-out fixing plate.

Description

technical field [0001] The invention relates to a cutting device, in particular to a fully automatic multi-station cutting machine. Background technique [0002] Notching (trimming) is an essential link in the production of stretched parts, especially for non-flange stretched parts, it is generally necessary to make a trimming die to complete the notch. [0003] In the prior art, there are many types of side trimming dies, which are gradually improved from the original single side cutting dies to the now widely used rotary cutting dies (see image 3 ). Single-side cutting means that each side of the shell is cut separately, which requires at least two molds and two operators to complete, and the efficiency is low. The current rotary cutting technology is to complete the mouth cutting on a mold, such as Figure 4 , Figure 5 As shown, in the working process, first put the shell into a block of equal height, then put the shell into the die, then the upper die moves down, pu...

Problems solved by technology

Single-side cutting refers to cutting each side of the shell separately, which requires at least two molds and two operators to complete, which is inefficient

The current rotary cutting technology is to complete the mouth cutting on a mold, such as Figure 4 , Figure 5 As shown, in the working process, first put the shell into a block of equal height, then put the shell into the die, then the upper die moves down, pushes the slider to move along the guide rail, and cuts the size of the shell respectively. This kind of cutting method is not suitable for square corner shells. There will be residues at the corners, which cannot be cut off. If the rounded corner shells are not cut in place, there will be large burrs at the corners, and a grinding process is required later, which is cumbersome to operate.

In addition, the rotary cutting operation needs to put a block of equal height in the shell and then put it into the mold, which requires particularly high sensitivity and hands-on ability of the employees. The employees need a long period of training and practice to achieve a certain production efficiency and production capacity
