Abstract
The invention relates to a rib rolling die, in particular to a special die for machining rib grooves on sheet surfaces by utilizing a numerical control rotating tower punching machine. The die comprises an upper die and a lower die, wherein the upper die comprises a beating head, a compressed spring, an upper die core, a guide sleeve and an upper roller; the lower die comprises a lower roller and a lower die holder; and the upper roller corresponds to the lower roller. The die is characterized in that: a piston section is arranged on the lower part of the upper die core; a piston cylinder section matched with the piston section is arranged on the upper part of the guide sleeve; the lower end of the guide sleeve is movably connected with the upper roller by a connection device; and an air vent communicated with the outside and the piston cylinder section is formed on the lower end face of the guide sleeve. The rib rolling die has a small and simple structure, and the high-precision rib grooves can be machined on the sheets.
Description
Technical field
The present invention relates to a kind of particular manufacturing craft that utilizes muscle groove on the NC turret punch machine processing sheet plate face.
Background technology
For improving the structural strength or the aesthetics of thin plate, on some plate faces, often need processing muscle groove.Such as cover plate of host computer boxboard, casing or the like.Carrying out this man-hour that adds, generally be to adopt punch forming in the past.Punch forming processing needs higher mould input cost, and working (machining) efficiency is low, and the process-cycle is long.On the thin-slab structure spare of, overlength size large-scale during the similar muscle groove of (such as automobile door, protecgulum, bonnet etc.) processing at some, needed die cost is higher, and the installation of mould, debugging difficulty are also bigger, and the scale of required supporting press is also very big.
Summary of the invention
The present invention is directed to above problem, provide a kind of and need not offer large mold, satisfy the rolling bar model tool of big specification production in conjunction with the feeding function of the high numerical control press of automaticity.
Technical scheme of the present invention is: comprise upper die and lower die, described patrix comprises attacking head, stage clip, upper mold core, guide pin bushing and upper roller, described counterdie comprises bottom roller and die shoe, upper roller is corresponding with bottom roller, described upper mold core bottom is provided with a piston section, described guide pin bushing top is provided with the piston cylinder section adaptive with the piston section, and described guide pin bushing lower end flexibly connects upper roller by jockey, and the guide pin bushing lower surface is provided with and is communicated with passage outside and the piston cylinder section.
Described piston segment length is less than the piston cylinder segment length, and both length differences are less than the limit compression travel amount of stage clip.
The present invention provides a kind of rolling bar model tool of special use for precision height, numerical control press that efficient is high, the cylindrical of guide pin bushing is set on the last station of numerical control press, die shoe is installed in down on the station, it is descending to drive the lathe staking punch again, keep this degree of depth to certain depth (reaching muscle groove projected depth) back, automatic feeding by punch press drives the plate motion at last, thereby can process the muscle groove on plate.Mould structure of the present invention is simple, small and exquisite, can process high-precision muscle groove on thin plate.

The specific embodiment
The present invention as shown in Figure 1, 2, comprise upper die and lower die, described patrix comprises attacking head 1, stage clip 2, upper mold core 3, guide pin bushing 5 and upper roller 8,5 upper port places are provided with spring base 4 at guide pin bushing, stage clip 2 is set on the die shank of upper mold core 3, and two ends contact the bottom surface of attacking head 1 and the end face of spring base 4 respectively.Described counterdie comprises bottom roller 8 and die shoe 10, upper roller 8 is corresponding with bottom roller 9, the bottom of described upper mold core 3 is provided with a piston section, described guide pin bushing 5 tops are provided with the piston cylinder section adaptive with piston section 11, described guide pin bushing 5 lower ends flexibly connect upper roller 8 by jockey, and guide pin bushing 5 lower surfaces are provided with and are communicated with passage 7 outside and the piston cylinder section.
The length of described piston section 11 is less than the piston cylinder segment length, and both length differences are less than the limit compression travel amount of stage clip 2.When not working, the end face of piston section 11 and piston cylinder section bottom surface keep certain clearance 6.
Claims (2)
1. rolling bar model tool, comprise upper die and lower die, described patrix comprises attacking head, stage clip, upper mold core, guide pin bushing and upper roller, described counterdie comprises bottom roller and die shoe, and upper roller is corresponding with bottom roller, it is characterized in that, described upper mold core bottom is provided with a piston section, described guide pin bushing top is provided with the piston cylinder section adaptive with the piston section, and described guide pin bushing lower end flexibly connects upper roller by jockey, and the guide pin bushing lower surface is provided with and is communicated with passage outside and the piston cylinder section.
