The spacing assembly 10 comprises a rotating handle 1001, a threaded portion 1002 is fixedly mounted on the surface of the rotating handle 1001, and a spacing portion 1003 is rotatably mounted on the surface, far away from the rotating handle 1001, of the threaded portion 1002 through a bearing. The rectangular clamping groove 608, the positioning hole 904 and the limiting part 1003 are matched in size.

In this embodiment, preferably, when in use, the clamping plate 903 is inserted into the square groove 605 until the pad 901 is attached to the side wall of the square block 603, then the limiting part 1003 is aligned with the positioning hole 904 and inserted into and clamped with the rectangular clamping groove 608, and then the threaded part 1002 is connected with the third threaded hole 607 through the rotating handle 1001, so that the square block 603 and the pad 901 can be effectively fixed, and the position fixation of the insert 7 is also realized; the later stage only needs the antiport turning handle 1001, can take off spacing portion 1003, loosens cardboard 903 and abaculus 7 again, and easy dismounting has alleviateed staff's work burden greatly.

As a further improvement of the present embodiment: in actual use, the shapes of the rectangular clamping groove 608, the positioning hole 904 and the limiting part 1003 can be changed, but the shapes of the rectangular clamping groove 608, the positioning hole 904 and the limiting part 1003 need to be kept consistent, so that after the threaded part 1002 is fixed, the clamping plate 903 and the insert 7 cannot move randomly.

The working principle and the using method of the invention are as follows: when the die is used, the upper die holder 2 slides downwards to drive the female die 4 and the side plate 501 to descend synchronously, the side plate 501 drives the embedded block 7 to descend synchronously through the telescopic rod 601, the square block 603, the clamping plate 903 and the base plate 901, and further the embedded block 7 and the female die 4 keep a synchronous descending trend; with the continuous decline of upper die base 2, the inclined hole 604 that square block 603 was seted up first contacts with the slope of guide bar 302, can drive square block 603 this moment and be close to curb plate 501, in this process: on one hand, the telescopic rod 601 and the spring 602 can be extruded, on the other hand, the embedded block 7 can be driven to be tightly attached to the inner wall of the female die 4, and the female die 4 is positioned above the male die 8; the square block 603 is driven by the upper die holder 2 to continuously descend, at the moment, the inclined hole 604 is in contact with the vertical part of the guide rod 302, the square block 603 does not move, the embedded block 7 is kept in a fit state with the inner wall of the female die 4, and the female die 4 is in contact with the male die 8 to start processing; after the processing is finished, the upper die holder 2 drives the square block 603 to ascend, and under the action of the telescopic rod 601 and the spring 602, the square block 603 finally keeps away from the side plate 501 and drives the embedded block 7 to be separated from the inner wall of the female die 4; in the whole process, the relative fixation of the embedded block 7 and the female die 4 is realized during descending, the smooth completion of part processing is ensured, and the embedded block 7 and the female die 4 are relatively separated during ascending;

when the insert 7 needs to be overhauled and replaced, the limiting part 1003 is separated from the rectangular clamping groove 608 and the positioning hole 904 only by rotating the rotating handle 1001, and then the insert 7 can be taken down; after the maintenance or replacement is finished, the clamping plate 903 is inserted into the square groove 605 until the cushion plate 901 is attached to the side wall of the square block 603, then the limiting part 1003 is aligned with the positioning hole 904 and inserted into and clamped with the rectangular clamping groove 608, and then the reverse rotating handle 1001 connects the threaded part 1002 with the third threaded hole 607, so that the effective limiting between the square block 603 and the cushion plate 901 can be realized, the position fixing of the embedded block 7 is also realized, and the disassembly and the assembly are more convenient;

through the matching of the structures such as the telescopic rod 601, the square block 603, the clamping plate 903 and the base plate 901, the embedded block 7 can be tightly attached to the inner wall of the female die 4 when the female die 4 descends, the normal operation of the die is ensured, the embedded block 7 can be separated from the inner wall of the female die 4 when the female die 4 ascends, and the quick overhaul and replacement of the embedded block 7 in the later period are facilitated; through the matching of structures such as the rectangular clamping groove 608, the positioning hole 904, the threaded part 1002 and the limiting part 1003, after the insert 7 is separated from the inner wall of the female die 4, the quick separation of the insert 7 can be realized only by screwing the rotating handle 1001, and meanwhile, the assembly and disassembly are simple and convenient, so that the labor burden of workers is greatly reduced; through base 301, hangers 502, backing plate 901 and first screw hole 11, can correspond the position of adjustment guide bar 302, square block 603, backing plate 901 and abaculus 7 to be applicable to more demands in the in-service use, holistic practicality is higher.
