Description
Technical field
The utility model is related to moulds of industrial equipment fields more particularly to a kind of novel pin key to flatten tooling.
Background technology
When daily machinery production and operation, usually fastener is needed to be fixed between machine components, conventional at present consolidates
Determine mode to be mainly fixed by the standard fasteners of helicitic texture, but in some specific occasions, for meet antivibration,
The fixed effects such as resistance to plucking, antitorque, locking, it is often necessary to be fixed using the fastener of some polymorphic structures, these abnormity are tight
Firmware includes a kind of pin key, and one end of pin key is flat structure, the other end is the strip structure with V-type groove, specific shape
Shape is as shown in Fig. 1 ~ 3, and letter L is pin key length in figure, and a is the length that pin key is not crushed, and b is the thickness that pin key flattens end 14
Degree.
Punching press usually is directly placed at the part that needs are processed to the punching press of the small parts such as pin key, bolt in the prior art
It on workbench, is then fixed using the clamping device being arranged on press work platform, finally by punch to processing part
Carry out punching press.Authorization Notice No. is that the Chinese utility model of 201880822 U of CN discloses a kind of bolt punching press slotting attachment,
Above-mentioned utility model is placed on the table by the bolt that needs are processed, and processing part is fixed by accommodating set, so
Punching press is carried out to the position that bolt needs to stamp using mating punch afterwards, bolt is all exposed to outside during punching press.
And the special-shaped pin key in the utility model is exposed to outer impact style special-shaped pin using above-mentioned whole due to needing part punching press
The be not crushed length of part of key is not easy to determine, and carry out being required for when punching press every time by punch and pin key collapsed position into
Row alignment, is unfavorable for the large-scale production of pin key.
Utility model content
The utility model provides a kind of novel pin key flattening tooling, it is therefore intended that it is flat to solve one end in the prior art
Shape structure, the other end carry out being required for when punching press by punch and pin key pressure every time when being the special-shaped pin key processing with V-type groove
Flat position is aligned, the technical issues of being unfavorable for the large-scale production of pin key.
To achieve the above object, a kind of novel pin key of the utility model flattens tooling and adopts the following technical scheme that：
Technical solution 1：It includes the punch for punching press pin key that novel pin key, which flattens tooling, and novel pin key flattens tooling and also wraps
Include the flattening tablet for placing pin key and for pin key positioning to be fitted in the positioning briquetting flattened on tablet, positioning briquetting
Direction flatten the downside of tablet and be equipped with groove for positioning and plug-in mounting pin key, positioning briquetting has for towards the punch
The leading flank of arrangement, the front end of groove are the open end extended on positioning briquetting leading flank, and rear end is equipped with for being kept off with pin key
The Stop structure only coordinated.
Advantageous effect：When special-shaped pin key is fixed directly or by easy pressing device in the prior art, special-shaped pin
The length that need not flatten position of key is not easy to determine, special-shaped pin key by punching press due to being influenced so that special-shaped pin key exists
The position of pin key is easy to shift during punching press repeatedly, and then influences the product qualified rate of special-shaped pin key, this practicality
Novel middle positioning briquetting limits the displacement of special-shaped pin key radial direction, and the depth of positioning briquetting upper groove so that special-shaped pin key is non-depressed flat
Partial length is guaranteed, and Stop structure limits the depth that pin key is inserted into groove so that the non-flattened portion of special-shaped pin key
Length unification, flatten tablet avoid direct impact of the punch to punching machine, protect punching machine parts without damage.
Technical solution 2：On the basis of technical solution 1, the front side for extending perpendicularly to positioning briquetting of the groove
Face.Along width direction so that the length of groove is the length of the non-flattened portion of pin key, facilitate the processing of pin key.
Technical solution 3：On the basis of technical solution 1 or 2, the groove is straight slot, and the rear end of groove is to extend to determine
The open end of position briquetting trailing flank.Straight slot processing is more convenient, and energy may be used in the open end that straight slot is located at locating piece trailing flank
The Stop structure being enough freely disassembled is blocked, and the replacement of Stop structure is facilitated.
Technical solution 4：On the basis of technical solution 3, the Stop structure is for blocking groove rear end
Rectangle plate.Rectangle plate facilitates processing, and the arbitrary side of rectangle plate is used equally for blocking open end, works as envelope
When stifled side needs replacing, replacement can be realized by adjusting the constant bearing of rectangle plate.
Technical solution 5：On the basis of technical solution 4, positioning briquetting and rectangle plate are fixed by threaded fastener
Together.Threaded fastener installation and removal are convenient and can reach good fastening effect.
Technical solution 6：On the basis of technical solution 5, the threaded fastener be screw bolt and nut, bolt also cross
Positioning briquetting and rectangle plate are equipped with spring washer between the nut and positioning briquetting of the bolt.Spring washer plays slow
The effect of punching.
Technical solution 7：On the basis of technical solution 1,2,4,5 or 6, positioning briquetting is the type that both ends are low, centre is high
The upper side of type platy structure, positioning briquetting both ends lower is disposed with the through-hole penetrated for bolt.Both ends are low to facilitate through-hole
It drills through.
Technical solution 8：On the basis of technical solution 7, the groove is rectangular channel.Rectangular channel and the pin key processed
The non-shape for flattening end is coincide, and good fixed function can be played to pin key.
Technical solution 9：On the basis of technical solution 8, flattens tablet and be fixed on work bench of punch press by briquetting, it is described
Briquetting is bolted on work bench of punch press.It need not be drilled on flattening tablet using briquetting and bolt so that fixed
Mode is simplified.
Technical solution 10：On the basis of technical solution 9, the impact end of the punch is chamfering close to positioning briquetting side
Structure.So that the junction of flattened portion and flattened portion is not arc grading structure to pin key, the intensity of junction is enhanced.
