the upper die base and the round core rod 6 reset, a product after being rolled is taken out from the round core rod 6, the material supporting block 10 reversely rotates and bounces under the action of the ejector pin 15 and the spring to realize resetting, then the next half of finished material enters the rolling component 13, and the actions are repeated to realize secondary rolling processing.
When the pipe fitting product moves into the cutting assembly 14, the upper die of the upper die assembly moves downwards, the upper concave seat 142 of the upper die set is attached to the cutting core rod 31 and the pipe fitting product attached to the core rod and continues to move downwards until the upper concave seat is attached to the lower concave seat 161, the spring of the upper concave seat 142 begins to compress, and the thickness space of the upper concave seat 142 begins to shrink;
and continuing to descend, the inclined wedge 30 contacts the sliding block 28 which descends along with the upper die, under the action of the backup plate 29, the sliding block 28 is pushed by the inclined wedge 30 to move to the right side, the sliding block spring 34 contracts and pushes the side push block 27 to move to the right side, the side push block 27 contacts the slitting knife 26 which is installed in the upper recess 142 in the process of moving to the right side, the slitting knife 26 moves downwards under the action of the cooperation of inclined edges, the slitting knife 26 extends to the lower part through the upper recess 142 and is cut off from the position where the pipe fitting product is connected by the extension cutting core rod 31, then the upper die assembly returns, the slitting knife 26 is separated from the cutting core rod 31, the spring action of the upper recess 142 restores the increased thickness space again, the slitting knife 26 returns to the inside the through hole of the upper recess 142, and simultaneously the inclined wedge 30 and the. Discharging the formed automobile silencing exhaust straight pipe.
Simultaneously, the waste material is pushed into a waste material groove in the extension cutting core rod 31, and an air hole is arranged in the waste material groove. Compressed air connected with the outside is introduced into the air holes, and the waste falling in the waste groove is blown out of the core rod.
The invention has the beneficial effects that: the device can realize one-time up-and-down movement of the upper die assembly and the lower die assembly, and complete the working procedures of punching, cutting, guiding, rounding and cutting at one time; the continuous automobile exhaust muffler has the advantages of high processing efficiency, low cost and the like, can realize continuous die making and stamping production of straight pipe fittings, combines various processes and characteristics on a set of continuous die, and realizes the function of continuous stamping production of inner pipe rolling. Therefore, the purposes of reducing the production cost generated in the production process, human resources and other links and improving the benefit are achieved.
The processing method based on the die is simple and practical.
