Technical scheme：A kind of Split type punching base for processing spanner described in the utility model, including punching bottom Seat low mold frame and punching base lower mold core, described punching base low mold frame is provided with mating holes, described punching base lower mold core It is inserted in described punching base low mold frame by described mating holes, described punching base low mold frame is secured within work bench of punch press On.

Further, described mating holes includes screens section and canned paragraph；Described punching base lower mold core includes drift Cooperation section and framed cooperation section, described punching base lower mold core is inserted in described cooperation in the hole from the bottom to top, and described drift Cooperation section stretches in described canned paragraph, and described framed cooperation section is stuck spacing by described screens section.

Further, described screens section internal diameter is 181 ± 0.2mm, and highly for 20 ± 0.2mm, the internal diameter of canned paragraph is 150.7 ± 0.2 mm, highly for 48 ± 0.2 mm；Described drift cooperation section internal diameter is 150.7 ± 0.2 mm, framed cooperation section Internal diameter is 180 ± 0.2 mm.

Further, described punching base low mold frame is fixed on work bench of punch press by U-shaped frock clamp.

Further, described spanner is double offset ring spanner.

Beneficial effect：（1）This utility model transform split as by the punching base novelty of traditional integral structure Formula structure, wherein punching base low mold frame can be saved with the similar multiple kinds of molds of common-use size it is achieved that maximally utilizing of material Save raw material, shorten the new die manufacturing cycle；（2）The punching base that this utility model provides only needs punching when using Base lower mold core is inserted in punching base low mold frame, then punching base low mold frame is fixed on work bench of punch press, behaviour Make easy, and structural stability is high.

Specific embodiment

Below by accompanying drawing, technical solutions of the utility model are described in detail, but protection domain of the present utility model It is not limited to described embodiment.

Embodiment：A kind of Split type punching base for processing spanner, including punching base low mold frame 2 and punching base Lower mold core 1, described punching base low mold frame 2 is provided with mating holes 7, and described mating holes 7 includes screens section 3 and canned paragraph 4；Institute The punching base lower mold core stated includes drift cooperation section 5 and framed cooperation section 6, and described punching base lower mold core 1 is from the bottom to top It is inserted in described mating holes 7, and described drift cooperation section 5 stretches in described canned paragraph 4, described framed cooperation section 6 is by institute The screens section 3 stated is stuck spacing；Described screens section 3 internal diameter is 181 ± 0.2 mm, highly for 20 ± 0.2 mm, canned paragraph 4 Internal diameter is 150.7 ± 0.2 mm, highly for 48 ± 0.2 mm；Described drift cooperation section 5 internal diameter is 150.7 ± 0.2 mm, mould Frame cooperation section 6 internal diameter is 180 ± 0.2 mm；Described punching base low mold frame is provided with installation groove, and solid by U-shaped frock clamp It is scheduled on work bench of punch press.

The instrument that this utility model provides is applied to the processing of double offset ring spanner, in use, by mould under punching base Core is inserted in punching base low mold frame from the bottom to top, is placed on together on the platform of punch press, and punch upper die is placed in punch press upper end, It is slowly put down, is coordinated with mould under punching, after cooperation debugging puts in place, with special frock clamp by mould under punching base Frame is fixed, because punching base lower mold core aspect ratio low mold frame is more slightly higher, and on the basis of positioning above end face, therefore, under End face presents lower mold core and projects than low mold frame, therefore only needs to fixing low mold frame and can achieve that mould installion finishes, operation letter Just.And, punching base low mold frame can be saved with the similar multiple kinds of molds of common-use size it is achieved that maximally utilizing of material Raw material, shortens the new die manufacturing cycle, is suitable to marketing.

Although as described above, having represented with reference to specific preferred embodiment and having described this utility model, it must not It is construed to the restriction to this utility model itself.In the spirit and scope of the present utility model defining without departing from claims Under the premise of, can various changes can be made in the form and details to it.
