Description
Technical field
The present invention relates to a kind of puncher, be specifically related to the symmetrical puncher of a kind of PU circle bubble centre bore.
Background technology
The polyurethane circle bubble that PU (polyurethane) circle bubble production line is produced utilized puncher to get through hole along the axle center of cylindrical foam before carrying out rotary-cut, utilized through hole to carry out wearing axle rotary-cut, produced thin coiled material.The quality of through hole directly has influence on utilization rate and the rotary-cut quality of semi-finished product circle bubble.There is following problem in existing puncher: (1), existing puncher is integral type cutter head (namely blade and swivel head weld together), in Long-Time Service process, blade passivation or damage can be caused unavoidably, around the cutter head rotated, easily form after passivation that foam is torn, the phenomenon of hole sideslip, spiral pit, cause the waste of sponge material.(2), existing puncher is unidirectional punching, when punching, because punching distance is longer, resistance is comparatively large, the diameter of punching can be made to change, make inside because excessive frictional resistance causes tearing of sponge, or cause hole to depart from center, with the through hole of this disalignment for after axle rotary-cut thin coiled material, the both sides of coiled material can form hypotenuse, thus cause too much foam waste, can not cut due volume; Because the segment design of puncher is sharp zigzag fashion, when taking out inner core after punching terminates, can cutter head be touched, easily occur the accident scratching hand.(3), determine that punch position visually observes central point artificially before punching, often there will be hole and depart from center phenomenon, especially in the production process of anxiety, not the too much time does not go to the position of correcting punching, and hole departs from center can make waste very large.
Summary of the invention
The present invention is that the axle center in order to solve the through hole stray circle cylindrical foam that existing puncher is got is excessive, easily makes circle bubble through hole produce a macropore, cause the problem that sponge material is wasted after integral type cutter head rust, provides a kind of PU circle bubble centre bore symmetrical puncher.
The symmetrical puncher of a kind of PU circle bubble centre bore of the present invention comprises base, mobile platform, chain, upper sensor, by movable sprocket, lower sensor, drive sprocket, traction electric machine, circle bubble support, article two, slide rail, two cylinders, two support bars, two bearings, two drive motors, two driving gears, two driven gears, two knife bars, two cutter heads and four slide blocks, article two, slide rail be arranged in parallel and is packed on base, every bar slide rail slidably connects two slide blocks, mobile platform is fixed on above four slide blocks, the two ends of chain are walked around respectively and are connected with the two ends, left and right of mobile platform with drive sprocket by movable sprocket, drive sprocket is packed on the output shaft of traction electric machine, two cylinders are arranged on above mobile platform, circle bubble Bracket setting is on two cylinders, the tail end of cylinder is connected with mobile platform, the piston end of cylinder steeps support with circle and is connected, two support bars are symmetricly set on the two ends of circle bubble support, the lower end of each support bar is fixedly connected with base, a bearing is installed in the upper end of each support bar, a drive motors installed by each bearing, the output shaft of each drive motors installs a driving gear, the driven gear engagement that each driving gear is corresponding with it, driven gear is packed in the tail end of knife bar, cutter head is equipped with in the front end of knife bar, cutter head is made up of tool rest and annular blade, the front end face of tool rest is provided with cannelure, annular blade is arranged in cannelure, lower sensor is arranged on circle bubble internal stent bottom surface, upper sensor and lower sensor are up and down just to setting.
The present invention compared with prior art has following beneficial effect:
1, annular blade and tool rest are designed to detachable connection by the present invention, the blade of polytype and quantity can be equipped with like this to meet the punching requirement of various model circle bubble, blade is easy to dismounting, changes conveniently, so blade there will not be passivation or damage, therefore, there will not be during punching that foam is torn, the phenomenon of hole sideslip, spiral pit, thus the waste of sponge material can not be caused, saved cost.
2, the present invention is two-way punching, knife bar length and travel distance can be made to reduce half, thus considerably reduce frictional resistance, avoid deviation phenomenon.The foam core simultaneously produced due to boring drilling can be stayed in foam, and need not contact cutter head when getting core can take out, and can avoid injury.Punching two ends design can make cutter head moment little, and the frictional force of generation is little, avoids the generation of offset tool phenomenon, makes running precision high.
3, the present invention devises upper sensor and lower sensor, and calculate the diameter of circle bubble and the position of central through hole by the data that upper sensor and lower sensor record, the shaft core position of central through hole and knife bar is adjusted by cylinder, central through hole position is accurate, there will not be the off-centered phenomenon of hole, achieve punching zero deflection, improve circle bubble volume recovery.
4, invention increases the quality of sponge punching, and have the advantages that lumber recovery is high, function is strong.
