The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
As depicted in figs. 1 and 2, present embodiment is a kind of chipless cutting machine, comprises frame, is arranged on clamp mechanism 1, drive motors 2, cutter sweep 3 and following fixture block elevating mechanism 11 on the frame.
Like Fig. 3 and shown in Figure 4; Said cutter sweep 3 comprises driving gear 5, rotating disk and cutter unit 7; Said driving gear 5 is installed in the rotating shaft of drive motors, and rotating disk is provided with the through hole that holds tubing, and the rotating disk circumference is provided with disk gear 4; Disk gear 4 and driving gear 5 engagements, the rotating disk front also is fixed with the circular fixed gear 6 around through hole.
Like Fig. 5 and shown in Figure 6, said cutter unit 7 comprises planetary gear 8, drive lead screw 10 and cutter 9, said fixed gear 6 and planetary gear 8 engagements, and the output shaft of planetary gear 8 is connected with drive lead screw 10, and the lower end of drive lead screw 10 is connected with cutter 9.
Cutter sweep 3 comprises preceding cutter unit, back cutter unit and the 3rd cutter unit that is provided with around through hole, planetary gear 8 engagements of fixed gear 6 and three cutter units 7.Wherein the cutter of preceding cutter unit are thinner than the cutter of back cutter unit and the 3rd cutter unit, and the cutter of preceding cutter unit are longer than the cutter of back cutter unit and the 3rd cutter unit.
Clamp mechanism 1 is the Pneumatic V clamp, comprises fixture block and following fixture block, and following fixture block is connected with following fixture block elevating mechanism 11.
Operation principle: after cutting machine receives cutoff signal, but air cylinder driven reducing scalable V-arrangement clamp 1 clamps the tubing of different size;
Because the wall thickness of tubing is thick more, the cutting force that needs is just big more; Traditional hydraulic pressure cutting system is bad to the assurance of cutting force, all is fixing a kind of hydraulic coupling feed during cutting, because the very big stress effect of the inner generation of tubing; Be easy to occur the phenomenon of " spoken parts in traditional operas " when cutting thick pipe.
The chipless cutting machine of present embodiment has been cast aside the thinking of traditional diced system, has developed a kind of system that utilizes mechanical gear drive cutter and rotating disk to cut synchronously.Driving gear 5 drives disk gear 4 motions, and when disk gear 4 drove the rotating disk rotation, the fixed gear 6 that is installed on the rotating disk also turned round, and planetary gear 8 receives the passive power effect of fixed gear 6, drives the running of feed screw mandrel simultaneously; Set up perfect drive connection between these gears, just permanent power.In the thick pipe of cutting, this drive connection has been brought into play good coordinative role, and when the wall thickness of tubing was thick more, the stress that cutter receive was just big more, and the feed force that needs is just big more; So, the resistance that planetary gear receives reduces the speed of rotating disk; But, so just playing the effect that incising pipes is carried out in dial rotation and cutting feed synchronously, better controlled is cut the strength of feed well.
Simultaneously, around rotating disk, designed 3 cutter units 7, the cutter of preceding cutter unit approach and grow, and scratch fine and deep seam together earlier on the surface of tubing; Then, utilize the thick and short performance of cutter of the cutter and the 3rd cutter unit of back cutter unit again, profoundly cut; In the process that forward and backward cutter, three cuttves cut simultaneously, the stress that tubing produces drops to minimum; The phenomenon that has reduced tubing " spoken parts in traditional operas " occurs.
Pneumatic V clamp 1 replaces traditional Hough clamp, adapts to the tubing of different size; Following fixture block is regulated down the height of fixture block to adapt to the variation of caliber through lifting motor 11.Designed the cost savings of clamp; Simultaneously, saved the time of changing clamp.
The diced system of the cutting machine of the utility model is mechanical structure, has substituted the structure of imported hydraulic system cutting fully, the time that provides cost savings and safeguard.
The utility model drives disk gear through a motor direct connection driving gear and rotates, and in addition, the planetary gear of the delivering gear on the rotating disk drives rotation by the fixed gear that is fixed on the rotating disk front wallboard, makes the delivering gear motion.Just changeing feed, the counter-rotating withdrawing.
Pneumatic V-type clamp replaces traditional Hough to clamp.No matter how the specification of tubing changes, this clamp mechanism can adapt to its tubing gripping range; Need not change fixture block and adjustment.
Brand-new feed mode design according to the thickness of tubing, can design 3 different cuttves simultaneously around disk.Before cutter thin and grow, back cutter is thick and lack, three cuttves are thick and mode that lack is made; Cutter approaches and long performance before utilizing, and cuts in tube surfaces earlier, produces the effect that little " contract type " divides mouth; Catch, the performance that back cutter is thick and short in the place that preceding cutter cuts " contract type mouth ", continues the feed cutting; Three cuttves continue " contract type mouth " local continuation feed cutting that cutter cuts in the back.Utilize the synchronizing function of rotating disk rotation and feed, in the process forward and backward, that three cuttves cut simultaneously, the stress that tubing produces drops to minimum, has reduced the phenomenon of " spoken parts in traditional operas " of otch.
This technology has the effect of update.Can improve the cutting reliability of tubing, realize the automation of cutting machine.
