Detailed description of the invention
The utility model provides a kind of rapid cutting device of brand-new bar.
As Fig. 1, above-mentioned rapid cutting device is plasma cutter, primarily of main spindle box 8, scroll chuck 7, plasma cut cutter 4, knife rest 12, run guide rail 1, synchronous pulley, peening hammer 9, Bar conveyor structure and work mounting s seat 3 form, scroll chuck 7 for clamping workpiece is connected to the main shaft of main spindle box 8, some work mounting s seats 3 are arranged on below main spindle box 88 front-end of spindle, and press the axial distribution of main spindle box 8 main shaft, the side of work mounting s seat 3 is located at by the operation guide rail 1 of plasma cut cutter 4, plasma cut cutter 4 is connected on corresponding knife rest 12, this knife rest 12 is slidably connected on motion guide rail 1, knife rest 12 is by a transmission mechanism transmission, the transmission mechanism transmission of the present embodiment is synchronous pulley driving mechanism, knife rest 12 is connected on Timing Belt, synchronous pulley engaged transmission Timing Belt, plasma cut cutter 4 and knife rest are moved along running guide rail 1, when moving to bar correspondence cutting position, the 4 pairs of bar cuttings of plasma cut cutter, complete the cutting to the whole desired location of bar thus.This cutting is cutting-in is 1/10 ~ 1/20 of bar diameter, cut wide for bar girth 2/5 ~ 3/5 incomplete cutting, form otch thus.After cutting completes, need to impact bar 2, thus bar 2 is truncated completely.Impact is impacted by the correspondence position of peening hammer 9 pairs of bar upper cuts, and this correspondence position preferred version is rightabout position with otch.Peening hammer 9 is arranged on the relative side running guide rail 1 and is positioned on the position in the middle of least significant end two work mounting s seats 3, has and only has an otch in the middle of two above-mentioned work mounting s seats 3.
As Fig. 3, peening hammer 9 is made up of with the hammer body 92 being positioned at eccentric disc arc top semicircular eccentric disc 91, drive (not shown) by the motor of correspondence, when eccentric hammer rises to extreme higher position, make it have at gravitional force, and under power drive, knock on bar, after blocking bar, bar comes off heavyly, peening hammer falls simultaneously, prepares to knock next time.
Bar 2 is truncated in peening hammer 9 position and comes off, and need to hit the next otch of bar 2, bar 2 needs axially to be carried.Therefore, the utility model is provided with Bar conveyor structure in the inside of work mounting s seat 2, as Fig. 2, this Bar conveyor structure is moving up and down is arranged on work mounting s seat inside, forms primarily of delivery wheel 37, bracing frame 34, worm gear 35, worm screw 36, first helical gear 31, second helical gear 32 and rotating shaft 33.Be positioned at the conveying of delivery wheel 37 for bar of the top, be connected on bracing frame 34 by rotating shaft 33, some delivery wheels 37 rotates by a power transmission shaft and somely to complete intermeshing Helical gear Transmission.One end of the rotating shaft of each delivery wheel 37 is connected with first helical gear, this first helical gear 31 is positioned at outside work mounting s seat, power transmission shaft each delivery wheel 37 position corresponding connects the second helical gear engaged with the first helical gear, first and second helical gear transmission drive delivery wheel 37 that engages each other that rotates through of power transmission shaft rotates, thus transmission bar moves axially.When delivery wheel 37 pairs of bars transmit, need to rise, the bar be originally bearing on supporting base is made to be bearing on delivery wheel 37, the bracing frame 34 being for this reason bearing in delivery wheel 37 vertical driving mechanism that need move up and down drives, the vertical driving mechanism of the present embodiment comprises the screw rod 38 of the lower end being arranged on bracing frame 34, center is provided with the worm gear 35 of screw and the worm screw 36 with this worm gear engaged transmission, worm gear 35 is screwed on screw rod 38 by the screw that center is arranged, because moving axially of worm gear 35 is restrained, during the rotation of worm screw 36 engaged transmission worm gear 35, the screw rod 38 of bracing frame 34 lower end will drive moving up and down of bracing frame 34.Worm screw 36 is horizontally disposed with, and engages thus ensure the uniformity moved up and down of the Bar conveyor structure on each work mounting s seat with worm gears 35 some in some supporting bases.
Said apparatus is before completing the cutting to bar 2, first by the scroll chuck 7 of the horizontal clamping in bar 2 one end of required processing on plasma cutter, then according to required bar length, at pc end, the cutting position of bar and Cutting Length and the degree of depth are set, after completing setting, start cutter sweep, controlled motion and the cutting of plasma cut cutter by pc end.In main spindle box, main shaft starts at the uniform velocity to rotate under the drive of motor, and drive the bar 2 of clamping on scroll chuck 7 at the uniform velocity to rotate by scroll chuck 7, simultaneously, plasma cut cutter 4 setting in motion, according to N number of station of setting, bar is cut one by one, each station is 1/10 ~ 1/20 of bar diameter to the cutting-in of bar, and cutting bar wide is 2/5 ~ 3/5 of girth, until form the N number of incomplete cutting mouth of setting.At incision site along the distribution of bar even circumferential, ensure that the cutting stress of bar is even.
Cutting completes, and plasma cut cutter 4 return, main shaft stops operating.Now, unclamp scroll chuck 7, bar 2 is placed on work mounting s seat 3, start to block bar.
Now, under the control of pc end, the Bar conveyor structure being positioned at work mounting s seat inside starts to rise under the drive of worm gear 34 worm screw 35, withstand bottom workpiece, gear shaft 10 starts to rotate, drive helical gear rotates, helical gear rotation drives delivery wheel to rotate, thus will bar be fed forward to peening hammer 10 position, now Bar conveyor structure declines, and bar drops on supporting base, and peening hammer 10 starts the strike carrying out lower a kerf correspondence position, so all cutting mouths of bar are knocked one by one, until bar breaks as N+1 section along cutting mouth.
In order to ensure that knocking of bar blocks efficiency, when bar being hit, generally needing the circumferential position adjusting bar, making incision site be positioned at hit position rightabout all the time, thus be conducive to blocking of bar.
The top being positioned at two work mounting s seats of the both sides of peening hammer is provided with one and is provided with protective cover 11, prevents in the process of knocking, and the segment bar be truncated is hit to fly, and produces potential safety hazard.
