Detailed Description
The technical scheme of the invention is further explained by combining the drawings and the embodiment.
Referring to the closed state of the transmission device of the red punching machine shown in fig. 1, two second protrusions 2 of the pull rod 1 are respectively matched with two second grooves 11 formed by a first open slot 8 of the first die sleeve 5 and a second open slot 9 of the second die sleeve 6, and can slide relatively. The two first projections 3 of the pull rod 1 are respectively matched with the two first grooves 7 of the first die sleeve 5 and the second die sleeve 6 and can slide relatively.
Referring to the open state of the transmission device of the red punching machine shown in fig. 2, the first die sleeve 5 and the second die sleeve 6 move back and forth along the two first protrusions 3, the first die sleeve 5 and the second die sleeve 6 are opened, the first protrusions 3 are still matched with the first grooves 7, the second protrusions 2 are separated from the second grooves 11, and at this time, the workpiece in the first die sleeve 5 and the workpiece in the second die sleeve 6 can be taken out. After the workpiece is taken out, the blank is put into the die cavities in the first die sleeve 5 and the second die sleeve 6, the first die sleeve 5 and the second die sleeve 6 respectively move along the two first lugs 3 in opposite directions, and the transmission device of the red punching machine returns to the closed state shown in the figure 1 and enters the next working cycle.
Please refer to fig. 3, which shows a structure of the pull rod. Two 1 st projections 3 are arranged at 180 degrees at the end face of the tie rod. The two second lugs 2 are respectively arranged at the end face of the pull rod at 90 degrees with the first lug 3.
Referring to fig. 4, the first and second sets 5 and 6 are shown assembled. First die sleeve 5 and second die sleeve 6 set up relatively, wholly be the toper, first die sleeve 5 and the 6 fitting surfaces of second die sleeve are provided with first open slot 8 and second open slot 9, form two second recesses 11 after first die sleeve 5 and the 6 closed of second die sleeve, the flatness of second recess 11 and the 2 fitting surfaces of second lug is 0.01 ~ 0.3mm, good flatness can guarantee that the cooperation of second recess 11 and second lug 2 is better, the atress is more even, first lug 3 and the difficult fracture of second lug 2. In order to ensure that the flatness of the first open slot 8 and the second open slot 9 after the first die sleeve 5 and the second die sleeve 6 are closed is 0.01-0.3 mm, the second groove 11 can be machined first, then the die sleeves are cut into the first die sleeve 5 and the second die sleeve 6 by machining methods such as wire cutting, and the first die sleeve 5 and the second die sleeve 6 are preferably provided with positioning. The second groove 11 has a rectangular or trapezoidal cross section.
A first groove 7 is further arranged on the axis of the closed first die sleeve 5 and the closed second die sleeve 6 and at a position perpendicular to the matching surfaces of the first die sleeve 5 and the second die sleeve 6, and the section 7 of the first groove is rectangular or trapezoidal. The first groove 7 arranged on the axis of the closed first die sleeve 5 and the closed second die sleeve 6 can not be perpendicular to the matching surfaces of the first die sleeve 5 and the second die sleeve 6, but the first die sleeve 5 and the second die sleeve 6 are stressed unevenly in the working process, so that torque is easily generated, and the service life of the die sleeves is influenced.
