The utility model solves the technical scheme that its technical problem adopted: the described hot rammer mould of stay bolt that adds is characterized in that: comprise the upper die and lower die and the unloading mechanism that are provided with from top to bottom, patrix connects slider of punch; Counterdie is fixedly connected with punch press bed body through lower bolster, and patrix comprises cope match-plate pattern and upper punch, and upper punch is installed in the cope match-plate pattern below; Counterdie comprises die shoe and is fixed on the cushion block case on the lower bolster that the cushion block case is positioned at the die shoe below, in the cushion block case cushion block is arranged; Upper and lower hexagonal mould and the circle mould of being provided with successively in the die shoe; The hexagonal mould is corresponding with the upper punch position, in the cylindrical channel of circle mould upper ejector pin is set, and the lower end of upper ejector pin contacts with cushion block; Cushion block case bottom is provided with lower push rod; Unloading mechanism comprises stripper and liftout bolt, and stripper is fixedly connected with cope match-plate pattern through column, and the liftout bolt on the stripper is corresponding with the position of lower push rod.
Add the hot rammer mould of stay bolt and need accomplish the moulding action of hex bolts,, therefore remain inactive state, and patrix is followed slider of punch and moved up and down because counterdie is fixed on the punch press bed body by existing punch press; When needs added stay bolt, patrix moved down, and carried out matched moulds up and down; Make the hexagon-head moulding that adds stay bolt, after the moulding of completion hexagon-head, retract the position on the patrix; Because stripper is fixedly connected with cope match-plate pattern through column, so stripper follows patrix and moves up, and at the last liftout bolt promotion lower push rod that moves past in the journey moulding bolt released from bed die; Product heat is upset and is accomplished, and manipulates simple and conveniently, can adjust the length of processing bolt simultaneously through pad thickness in the cushion block case and quantity; Can realize a tractor serves several purposes, practical, changing length specification only needs cushion block is adjusted; Time saving and energy saving, can the processing length scope be the product of 65mm~700mm, applied range.
In the described cope match-plate pattern transverse slipway is set, arm-tie is arranged in transverse slipway, and drift is installed through upper bolster in the arm-tie rear end.Through transverse slipway and arm-tie are set; Can before placing bar, pass through arm-tie, be convenient to the bar of need processing is put into counterdie, after bar is put well upper punch slow astern segment distance; Arm-tie is pulled to the center, makes upper punch corresponding with the hexagonal mould position of counterdie.
Described arm-tie is provided with locating rack, and locating rack is provided with bolt, can adjust the center and the displacement of arm-tie through the positioning screw cap on the adjustment bolt.
The beneficial effect that the utility model had is:
Add the hot rammer mould of stay bolt and accomplish the moulding action of hex bolts by existing punch press; Make upper and lower mould matched moulds through moving down of slider of punch; Completion adds the hexagon-head moulding of stay bolt; When moving on the slider of punch, unloading mechanism is released the moulding bolt automatically from counterdie top, manipulate simple and convenient; Transverse slipway is set in the cope match-plate pattern, and at transverse slipway arm-tie is set, through regulating the arm-tie position, can easily the bar that needs processing be put into counterdie, structure is flexible, easy operating; Thickness and quantity through cushion block in the adjustment cushion block case just can adapt to the machine-shaping that different length adds stay bolt, have realized a tractor serves several purposes, save cost and practical, and changing length specification only needs cushion block is adjusted, time saving and energy saving.
