Description
Technical field
The present invention relates to a kind of puncher, and in particular to a kind of PU circles bubble symmetrical puncher of centre bore.
Background technology
The polyurethane circle bubble that PU (polyurethane) circle bubble production lines are produced is before rotary-cut is carried out using puncher along cylinder
Hole is got through in the axle center of shape foam, carries out wearing axle rotary-cut using through hole, produces thin coiled material.The quality of through hole directly influences half
The utilization rate and rotary-cut quality of finished product circle bubble.There is problems with existing puncher：(1), existing puncher is integral type cutter head
(i.e. blade and swivel head welds together), during long-term use, can cause blade passivation or damage unavoidably, after passivation easily
The phenomenon of foam tear, hole sideslip, spiral pit is formed around the cutter head of rotation, the waste of sponge material is caused.(2) it is, existing
It is unidirectional punching to have puncher, and in punching, because punching distance is more long, resistance is larger, the diameter that can make punching changes,
Make internal because excessive frictional resistance causes the tear of sponge, or causes the off-center position of hole, with this off-axis
The through hole of the heart is for after axle rotary-cut thin coiled material, the both sides of coiled material can form hypotenuse, so as to cause excessive foam to waste, can not cut
Due volume；Because the segment design of puncher is sharp zigzag fashion, can be contacted when inner core is taken out after punching terminates
To cutter head, easily there is the accident for scratching hand.(3) determine that punch position is by artificially visually observing central point, often before, punching
The off-center phenomenon of hole occurs, especially in nervous production process, the not excessive time goes what corrigendum was punched
Position, hole is off-center to make waste very big.
The content of the invention
The present invention is for excessive, the integral type knife that solves the axle center of the through hole stray circle cylindrical foam that existing puncher is got
Circle bubble through hole is easily set to produce a macropore after head rust, the problem for causing sponge material to waste, there is provided a kind of PU circles bubble centre bore
Symmetrical puncher.
A kind of PU circles symmetrical puncher of bubble centre bore of the invention includes base, mobile platform, chain, upper sensor, quilt
Movable sprocket, lower sensor, drive sprocket, traction electric machine, circle bubble support, two slide rails, two cylinders, two support bars, two
Bearing, two motors, two driving gears, two driven gears, two knife bars, two cutter heads and four sliding blocks, two
Slide rail is be arranged in parallel and is packed on base, and two sliding blocks are slidably connected on every slide rail, and mobile platform is fixed on four cunnings
Above block, the two ends of chain bypass passive sprocket wheel and drive sprocket and are connected with the left and right two ends of mobile platform respectively, drive sprocket
It is packed on the output shaft of traction electric machine, two cylinders are arranged on above mobile platform, circle bubble support is arranged on two cylinders
Above, the tail end of cylinder is connected with mobile platform, and the piston end of cylinder is connected with circle bubble support, and two support bars are symmetrical arranged
At the two ends of circle bubble support, the lower end of each support bar is fixedly connected with base, and a bearing is installed in the upper end of each support bar,
One motor is installed on each bearing, a driving gear, each driving tooth are installed on the output shaft of each motor
The corresponding driven gear engagement of wheel, driven gear is packed in the tail end of knife bar, and the front end of knife bar is equipped with cutter head, and cutter head is by sky
Heart tool rest and annular blade are constituted, and the front end face of hollow tool rest is provided with annular groove, and annular blade is arranged in annular groove, lower sensing
Device is arranged on circle bubble internal stent bottom surface, and upper sensor is with lower sensor up and down just to setting.
The present invention has the advantages that compared with prior art：
1st, annular blade is designed as detachable connection by the present invention with hollow tool rest, can so be equipped with polytype sum
The blade of amount meets the punching requirement of various models circle bubble, and blade is readily disassembled, replacing facilitates, so blade is not in blunt
Change or damage, therefore, be not in foam tear, hole sideslip, the phenomenon of spiral pit during punching, so as to not result in sponge
The waste of material, has saved cost.
2nd, the present invention is two-way punching, and knife bar length and travel distance can be made to reduce half, is rubbed so as to considerably reduce
Wipe resistance, it is to avoid deviation phenomenon.Simultaneously because drilling drilling produce foam core can stay in foam, during coring without
Contact cutter head is that can be taken off, and can be avoided injury.Punching two ends design can make cutter head torque small, and the frictional force of generation is small, it is to avoid
The generation of offset tool phenomenon so that running precision is high.
3rd, the present invention devises sensor and lower sensor, and the data meter measured by upper sensor and lower sensor
The diameter of circle bubble and the position of central through hole are calculated, the shaft core position of central through hole and knife bar, central through hole are adjusted by cylinder
Position is accurate, is not in the off-centered phenomenon of hole, realizes punching zero deflection, improves circle bubble volume recovery.
4th, the present invention improve sponge punching quality, and with lumber recovery it is high, function is strong the characteristics of.
