Description
Technical field
The utility model relates to riveting equipment fields, and in particular to a kind of flanging formed punch for riveting.
Background technique
It is well known that previous, as the method that sheet metal and sheet metal is fixed, generally by spot welding by product
Riveting is combined together, this technique needs professional operator, equipment, and consumptive material is copper electrode, and processing cost is high, on the other hand, due to copper
Electrode surface oxidation causes riveting intensity inconsistent, will lead to weld discontinuity；It is gradually riveted technique institute's generation later
Replace, common riveting process is that sheet metal is first gone out flanging bore, then sheet metal is turned again, to flanging bore into
Row pressing, so that sheet metal rivets together；Therefore occurs the formed punch of various different purposes in the market；But for combination
The connection of formula formed punch is generally using threaded connection, but formed punch at work would generally be by biggish stress, and then screw thread produces
Therefore raw deformation, then needs the flanging formed punch for riveting of one kind newly to change so that the connection of knockdown formed punch is stuck
Kind drawbacks described above.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides a kind of flanging formed punch for riveting,
Being made its screw thread by larger stress at work its object is to traditional Combined punch pin, deformation occurs and leads to its connection card
Dead defect.
To achieve the above object, the utility model uses the following technical solution:
A kind of flanging formed punch for riveting, packet include formed punch ontology, the buffer part for protecting formed punch ontology and with
Formed punch ontology is adapted the enlarged portion for the perforation of flange multiple diameter；It is detachable solid between the formed punch ontology and enlarged portion
It connects, the buffer part is arranged between the formed punch ontology and enlarged portion.
Compared with the prior art, the utility model has the following beneficial effects: in use, the sheet metal that needs are riveted
It is overlapped on the mold being placed below the formed punch, is then turned on punching machine and makes formed punch downward on sheet metal designated position
Flanging bore is gone out, then formed punch is retracted, the sheet metal is overturn, punching machine is again started up, so that formed punch is downwardly into flange
In hole, flanging bore is pressed；Therefore in formed punch work, buffer part can effectively slow down to be connected between formed punch and enlarged portion
The stress for connecing node prevents from generating deformation at link position and leading to stuck phenomenon；Therefore, the present apparatus being capable of effective improvement group
There is the drawback for causing the two stuck due to deformation occurs at connecting node in box-like formed punch.

Fig. 1 is the broken away view of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Fig. 3 is the structural schematic diagram of the non-installation sleeve of the utility model.
Fig. 4 is the bottom view of the utility model.
Wherein: perforated portion 1, cutting edge 101, flared end pressed flat 2, interconnecting piece 3, sleeve 4, enlarged portion 5, first be placed in slot 6,
Second merging slot 7
Specific embodiment
The technical solution in the utility model is further illustrated with reference to the accompanying drawings and embodiments.
As shown in Figs 1-4, the utility model proposes a kind of flanging formed punches for riveting, including formed punch ontology, use
It is adapted in the buffer part for protecting formed punch and with formed punch the enlarged portion 5 perforated for flange multiple diameter；Formed punch ontology bottom
Detachable affixed between portion and enlarged portion 5, the buffer part is arranged between the formed punch ontology and enlarged portion 5, works as formed punch
Ontology dismantled from enlarged portion 5 under when, the buffer part can also be removed；In use, the sheet metal for needing to rivet is overlapped
It is placed on well on the mold below the formed punch, is then turned on punching machine and formed punch is gone out on sheet metal designated position downward
Flanging bore, then formed punch is retracted, the sheet metal is overturn, punching machine is again started up, so that formed punch is downwardly into flanging bore,
Flanging bore is pressed；Therefore in formed punch work, buffer part, which can effectively slow down, connects section between formed punch and enlarged portion 5
The stress of point prevents from generating deformation at link position and leading to stuck phenomenon；Therefore, the present apparatus can effectively improve combined type
There is the drawback for causing the two stuck due to deformation occurs at connecting node in formed punch.
As shown in Figure 1-3, the buffer part is sleeve 4, and 4 sets of the sleeve are leaned in the formed punch ontology in the present embodiment
Nearly 5 one end of enlarged portion, and the both ends of the sleeve 4 are bonded with formed punch ontology with enlarged portion 5 respectively, so that sleeve 4, formed punch ontology
Seamless connection is realized between enlarged portion 5, therefore, in present apparatus punching/pressing flange, can effectively slow down formed punch ontology
The stress that connecting node is subject between the enlarged portion 5, so that stress directly passes through 4 guiding expanding portion of sleeve from formed punch ontology
5 with the contact end node of sleeve 4；The present apparatus can be effectively reduced between formed punch ontology and enlarged portion 5 suffered by connecting node
Stress.
As shown in Figs 1-4, in the present embodiment, the formed punch ontology includes perforated portion 1, flared end pressed flat 2 and interconnecting piece 3；
The perforated portion 1, flared end pressed flat 2 and interconnecting piece 3, which are sequentially distributed, is combined into the formed punch ontology, the perforated portion 1 and flared end
Pressed flat 2 forms ' several ' character form structure, and the cross-sectional area of the interconnecting piece 3 is less than the flared end pressed flat 2 close to interconnecting piece 3
The cross-sectional area of end face；The sleeve 4 is then covered on interconnecting piece 3, and 4 internal orifice dimension of sleeve is adapted with the interconnecting piece 3；
Described 5 one end of enlarged portion is equipped with for sleeve 4 and the compatible merging slot of interconnecting piece 3, and the flared end pressed flat 2 is close to perforated portion 1
One end is cone-shaped structure；The present apparatus had both been able to achieve the perforation to sheet metal, moreover it is possible to which realization flattens flanging bore, may be used also
By replacement formed punch ontology to reach the flanging bore for being pierced by different pore size, and can also flared end pressing be carried out to flanging bore；Simultaneously
Maintenance, the replacement in later period can also be facilitated.
As shown in Figure 1-3, the merging slot is divided into the first merging slot 6 and the second merging slot 7 in the present embodiment；Described
The setting coaxial with the second merging slot 7 of one merging slot 6, and the cross-sectional area of the first merging slot 6 is greater than the second merging slot 7
Cross-sectional area；The first merging slot 6 is adapted with the flared end pressed flat 2 close to one end of interconnecting piece 3, so that ought not pacify
When sleeved 4, the flared end pressed flat 2 is inserted into the first merging slot 6 close to one end of interconnecting piece 3, and is just adapted；Institute
The end face that the side wall and the enlarged portion 5 for stating flared end pressed flat 2 are equipped with one end that first is placed in slot 6 is connected into a smooth cone
The curved surface that bodily form flared end flattens；When the non-installation sleeve 4 of the formed punch, the length of the interconnecting piece 3 is equal to the depth of merging slot.
As shown in Figure 1-3, the interconnecting piece 3 is equipped with external screw thread in the present embodiment, the second merging slot 7 is equipped with interior spiral shell
Line；The connection type of internal and external screw thread is easy to disassemble.
