Description
Technical field
This utility model belongs to the puncturing technique field of high-velocity forging product, is specifically related to a kind of drift hammer and perforation die fit structure.
Background technology
Owing to having, production cost is low, beat fast in forging at a high speed, and the advantages such as formed precision height can realize quick shaping, and environmental effect is little are widely applied at automobile gearbox parts, bearing industry.But needing the product of perforation when batch production for some, drift hammer easily occurs as soon as burning and melts, and punch end face there will be the openning that one burning is melted, and what slight crack too deeply just need to be reprocessed or abandon scraps, and directly affects production efficiency and extends the order delivery time.
Utility model content
For problems of the prior art, the purpose of this utility model is that design provides a kind of drift hammer and perforation die fit structure.
Drift hammer and perforation die fit structure, including drift hammer and perforation die, the cooperation of described drift hammer center is provided with push rod, drift hammer left end is provided with alloy portion, vent bore it is provided with in the middle part of drift hammer, drift hammer right-hand member is arranged in drift overlaps and pierce punch can be movable relative to drift set, it is provided with, on the left of described drift set, the stripper being equipped with drift hammer, the outside dimension of described drift hammer is 73.05-73.15, described perforation die is equipped with at product left end to be perforated, the cooperation of perforation die outer ring is provided with centering die, die gland it is provided with outside centering die, the internal diameter size of described perforation die is 74.45-74.55.
Coordinate between described drift hammer with drift set and be provided with cushion block.
Described stripper is connected with cushion block by fixed plate.
The outside dimension of described drift hammer is 73.1, and the internal diameter size of described perforation die is 74.5.
Described drift hammer and stripper matched in clearance.
Matched in clearance and bilateral gap both when described drift hammer penetrates in perforation die is 1.3-1.5.
Matched in clearance and bilateral gap both when described drift hammer penetrates in perforation die is 1.4.
This utility model can improve the life-span of drift hammer, and the product produced can meet the needs in market, improves work efficiency, shortens the order delivery time, creates bigger income.

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further detail, and provides detailed description of the invention.
nullAs Figure 1-4，Drift hammer and perforation die fit structure，Including drift hammer 1 and perforation die 2，The cooperation of described drift hammer 1 center is provided with push rod 3，Owing to drift hammer 1 left position cutting edge stress is bigger，It is low that easy burning melts the life-span，So replacing with alloy material，So drift hammer 1 left end is provided with alloy portion 4，Vent bore 5 it is provided with in the middle part of drift hammer 1，Drift hammer 1 right-hand member is arranged in drift overlaps 6 and pierce punch 1 can move forward and backward relative to drift set 6，Coordinate between described drift hammer 1 with drift set 5 and be provided with cushion block 11，It is provided with, on the left of described drift set 6, the stripper 7 being equipped with drift hammer 1，Drift hammer 1 and stripper 7 matched in clearance，Stripper 7 is connected with cushion block 6 by fixed plate 12，The outside dimension of drift hammer 1 is 73.05-73.15，Preferably 73.1，Described perforation die 2 is equipped with at product 8 left end to be perforated，The cooperation of perforation die 2 outer ring is provided with centering die 9，Die gland 10 it is provided with outside centering die 9，Product 8 is fixed together with perforation die by centering die 9 die gland 10，It is 74.45-74.55 with the internal diameter size of described perforation die 2，Preferably 74.5，Matched in clearance and bilateral gap both when drift hammer 1 penetrates in perforation die 2 is 1.45，Now the frictional force between drift hammer 1 and perforation die 2 is smaller，Be conducive to improving the service life of drift hammer.
During work, under the promotion of drift hammer 1 power in the wings, the direction towards product 8 direction is moved, through product 8 and go out material core 13 while also through perforation die 2, after passing perforation die 2 completely, material core 13 is ejected by push rod 3, and material core 13 falls, drift hammer 1 is with the product rollback after being perforated, product after back off procedure middle punch is blocked by stripper 7, and drift hammer 1 returns to origin-location, and the product after boring a hole falls and carry out next step processing.
Above-mentioned embodiment is only to be described preferred implementation of the present utility model, is not defined spirit and scope of the present utility model.On the premise of without departing from this utility model design concept, various modification that the technical solution of the utility model is made by this area ordinary person and improvement, protection domain of the present utility model all should be dropped into.
