Technical field

The invention belongs to air hose manufacturing fields, more specifically to a kind of high-precision bending equipment and its bending method With air hose production line.

Background technique

It is well known that air hose is the pipe-line system for air delivery and distribution, it is widely used in various industries field In, it is one of an indispensable part in industrial production.By cross sectional shape, air hose can be divided into circular duct, rectangular air duct, oblate Air hose etc. is a variety of, and wherein the resistance of circular duct is minimum, but due to the height dimension of circular duct maximum, makes more multiple It is miscellaneous, so being still at present rectangular air duct with most air hoses.

In traditional air hose production mainly by the way of artificial, such as production rectangular air duct, it needs manually to cut plate It is split into left plate, right side plate, top plate and bottom plate, then will adopt and nail after left plate, right side plate, top plate and floor combination Form air hose.This production method needs are a large amount of artificial, and efficiency is very low, and air hose leakproofness caused by system is poor, because This, occurs processing air hose in a manner of air hose production line on the market.

Air hose production line in production work, from coiled strip under expect that the molding whole process of air hose is set by machining Standby independent uninterrupted completion, pilot process do not need anyone participation and operation.It generally includes discharging frame, material supporting rack, tune The multiple equipments such as flat beading machine, stamping die, plate shearing machine, rumble bone machine, feed device, flange machine.Wherein, leveling beading machine is used for Radial rib slot is suppressed after leveling by plate and become straight, on plate convenient for the following process of plate；Rumble bone machine is used for cutting Plate after cutting, which carries out processing, makes plate two sides form flanging, and splicing closure subsequent for plate is indispensable equipment； Feed device is playing always plate conveyor material in the course of work of the entire production line, especially send plate to bending and sets When standby, need accurately to send plate to scheduled bending position, guarantee that the air hose shape finally processed is accurate.

Firstly, the wall thickness of the air hose needed is usually different in different fields, therefore the tune in air hose production line Flat beading machine usually requires to adjust the spacing between up-down rollers according to the plate of different-thickness.

Specific embodiment

The present invention is further described below with attached drawing combined with specific embodiments below.

Embodiment 1

As shown in figure 3, present embodiments providing a kind of leveling beading machine, it is mainly used for adjusting tortuous plate It is flat, and beading operation is carried out to plate after so that plate is become straight, longitudinal rib slot is extruded on plate.The leveling beading machine is main Including a pair of side plates 315 and the charging roller group being sequentially arranged in a pair of side plates 315, leveling roller group, beading roller group and measurement roller Group.Wherein, charging roller group reduces pulling load of the plate in process below, so that feeding is more smooth for pushing plate； Leveling roller group makes plate become straight for flattening to plate；Beading roller group is used to extrude longitudinal rib slot on plate, indulges It will eventually become the muscle slot on air hose section side to muscle slot；Measurement roller group can be sent out by the revolving speed of detection measurement roller to calculate Plate length, facilitate the following process of plate.Below to the structure of each roller group and side plate 315, working principle and each other Between installation relation be described in detail, and provide the application method of the leveling beading machine on this basis.

As shown in Fig. 3 to Fig. 7,315 upper end edge feedstock direction of side plate successively offers feed roller mounting groove 311, leveling roller Mounting groove 312, beading roller mounting groove 313 and measurement roller mounting groove 314 are then opened respectively on the side plate 315 below each mounting groove Equipped with multiple mounting holes.It positions and connects by support rod 322 between a pair of side plates 315, the support rod 322 of this programme is using double The structure of head screw rod, support rod 322 are each passed through the corresponding one group of mounting hole in position in a pair of side plates 315, and both ends then lead to Nut is crossed to lock respectively with two blocks of side plates.When assembling level beading machine when, first by support rod 322 to two blocks of side plates 315 into Row is connected and is positioned, so that the relative position of corresponding mounting groove and mounting hole is accurate in a pair of side plates 315, to enable subsequent The installation of each roller group is more convenient, and the position after installation is more accurate.

Charging roller group includes upper feeding roller 301, lower feed roller 302 and a pair of of elevating mechanism 320, the elevator of the present embodiment Structure 320 uses Worm gear feed screw elevator.The both ends of upper feeding roller 301 pass through the corresponding peace of one piece of mounting plate moving up and down respectively In two feed roller mounting grooves 311, a pair of of mounting hole, the both ends of upper feeding roller 301 are correspondingly arranged on two pieces of mounting plates It is mounted in a pair of of feed roller mounting groove 311 after the mounting hole being each passed through on two pieces of mounting plates by bearing support.A pair of of snail Wheel screw lift is located above the both ends of upper feeding roller 301, and the upper beam body 321 of upper part and 315 upper end of side plate is fixed It connecting, the screw rod lower part in Worm gear feed screw elevator is then fixedly connected with mounting plate, so, pass through and manipulates Worm gear feed screw elevator The height at 301 both ends of upper feeding roller can be controlled by carrying out lifting work.In order to guarantee the adjustable height at 301 both ends of upper feeding roller Consistency, the Worm gear feed screw elevator at 301 both ends of upper feeding roller are linked using same root worm screw, by control the worm screw into Row rotation, can drive the Worm gear feed screw elevator at both ends to synchronize lifting work, guarantee the height at 301 both ends of upper feeding roller It unanimously, will not run-off the straight.Lower feed roller 302 passes through the mounting hole of 311 lower section of feed roller mounting groove and is pacified by bearing support Between a pair of side plates 315, height change will not occur in the leveling beading machine course of work, therefore, by controlling snail The height that wheel screw lift adjusts upper feeding roller 301 can control the rolling spacing between upper and lower feed roller, to adapt to difference The plate of thickness.

Leveling roller group includes three up-regulation plain-barreled rolls, 303, three downward plain-barreled rolls 304 and two pairs of elevating mechanisms 320, elevating mechanism 320 use Worm gear feed screw elevator, have done very big improvement compared to the leveling roller group in conventional leveling beading machine, have been these Highly important improvement in scheme.In conventional leveling beading machine, the roller quantity of leveling up and down for leveling roller group is typically not greater than Two pairs, and when the roller spacing for exchanging plain-barreled roll is adjusted, it can generally keep each consistent to the roller spacing between upper and lower leveling roller, roller Spacing can be slightly more than the thickness of plate, to guarantee good levelling effect.But since plate itself has certain song Folding, and the size of the tortuosity of a roll of plate has certain difference, so if roller spacing is arranged to thick slightly larger than plate The size of degree, then tortuosity biggish plate in part is easy to block and block between up-down rollers, causes subsequent plate can not It transports, influences the normal work of equipment, however if the setting of roller spacing is larger, leveling roller group will for the levelling effect of plate Become poor, influences the following process of plate.

In order to solve this problem, the up-regulation plain-barreled roll 303 in the present embodiment is mounted on two leveling rollers by bearing support In mounting hole in a pair in mounting groove 312 in roller bearing 316, when upper roller bearing 316 is when in a horizontal state, peace thereon Dress hole is in sustained height, lowers plain-barreled roll 304 and is then mounted on leveling 312 lower section side plate 315 of roller mounting groove by bearing support Mounting hole in.Two pairs of Worm gear feed screw elevators are located at 316 liang of upper sides of roller bearing in a pair, solid by upper beam body 321 On side plate 315, screw lower end is fixedly installed with one piece of mounting plate for Dingan County, and mounting plate is inserted into a pair of upper roller bearing respectively The regulating tank 317 of 316 both sides of the upper end is simultaneously articulated and connected with upper roller bearing 316, positioned at the one of two pieces of upper 316 the same sides of roller bearing To the lifting work for controlling upper 316 the same side of roller bearing between Worm gear feed screw elevator by worm-drive connection.In reality In production, we can control the liter that two pairs of Worm gear feed screw elevators carry out a different height to the both ends of upper roller bearing 316 Work is dropped, roller bearing 316 is made to occur to swing in this case and it is finally enabled to be higher than close to the height of feedstock direction one end The height of the other end, therefore, the three roller spacing for exchanging plain-barreled roll will be in a situation gradually successively decreased from feed end to discharge end. When plate is conveyed between leveling roller group, the complications of a part can be equalled by the biggish leveling roll-in of roller spacing first, because This, again will not be because of roller spacing while tortuosity can further become smaller when its leveling roller small-pitch using roller below Become smaller and the phenomenon that gets stuck, to reach a fairly perfect levelling effect.More importantly by the way that three are leveled Roller 303 is mounted on a pair of of upper roller support 316, and the roller spacing that plain-barreled roll can be exchanged by adjusting upper roll support 316 has one The adjusting of globality, so that the three roller spacing for exchanging plain-barreled roll may remain in one from feed end to discharge end and extremely accurately pass Subtract angle, and due to being that monoblock type is adjusted, when replacing the plate of different-thickness, it is only necessary to will be close to a pair of of leveling of discharge end The roller spacing of roller is arranged to the size slightly larger than sheet thickness, then by the Slope angle adjustment of upper roller bearing 316 at the angle of setting , convenient and efficient and setting is precisely.

In addition, successfully being swung to cooperate upper roller bearing 316 to carry out one in leveling roller mounting groove 312, in upper roller The two sides of support 316 are provided with concentric circular arc and adjust face 325, and circular arc adjusts face 325 and levels the two sides of roller mounting groove 312 It is engaged, preventing the two sides mutual extrusion of its two sides and leveling roller mounting groove 312 when roller bearing 316 is swung cannot The case where moving.In addition, the position that the bottom of upper roller bearing 316 corresponds to up-regulation plain-barreled roll 303 has downward arc convex, adjust Then there is the mutual corresponding arc groove of arc convex with upper 316 bottom of roller bearing, when upper on the bottom surface of plain-barreled roll mounting groove 312 When roller bearing 316 is swung, the arc groove phase interworking of upper 316 bottom arc convex of roller bearing and leveling 312 bottom surface of roller mounting groove It closes, allows roller bearing 316 to have a bigger swing angle, to adapt to the adjusting of the plate to a variety of different-thickness. Furthermore due to upper roller bearing 316 need by swing come so that leveling roller roller spacing be gradually reduced from feed end to discharge end, Therefore it is likely to that the leveling work for being displaced to influence to level roller group of a part occurs in the axial direction of leveling roller.Cause This, the present embodiment is provided with block 319 in the two sides of upper roller bearing 316, and block 319 is arranged between a pair of side plates 315 and divides It is not engaged with a pair of side plates 315, for limiting upper roller bearing 316 in the axially displaced situation of leveling roller.Secondly, Because upper roller bearing 316 needs to adjust its gradient, the peace of upper roller bearing 316 and screw rod bottom end by the swing of itself Using articulated connection between loading board, therefore, inevitably exist between part between upper roller bearing 316 and mounting plate Gap.When leveling beading machine work, upper roller bearing 316 and mounting plate can due to gap presence and the shake of different frequency occurs Dynamic, so that occurring mutually to collide between the two and causing to damage, in order to solve this problem, the present embodiment is in upper roller bearing 316 Downside both ends also offer a spring mounting hole 318 respectively, spring mounting hole 318 is provided with adjustment spring 310, adjusts bullet The bottom support of spring 310 is arranged on the bottom surface of leveling roller mounting groove 312.310 one side of adjustment spring can by itself The height of upper roller bearing 316 is adjusted in elastic force assistance for lifting mechanism 320, on the other hand can eliminate elevating mechanism 320 with The gap of upper 316 junction of roller bearing, so that being consistent property of movement between the two, prevents leveling beading machine in long-time work It is damaged during making.

Beading roller group includes that upper beading roller 306, lower beading roller 307 and a pair of of elevating mechanism 320, elevating mechanism 320 use Worm gear feed screw elevator.As the mounting means of charging roller group, upper beading roller 306 is mounted on two beadings by bearing support Between a pair of of mounting plate in roller mounting groove 313, a Worm gear feed screw elevator, a pair of of snail are separately connected above two pieces of mounting plates Link by same root worm screw between wheel screw lift and 315 upper end of side plate is fixedly mounted on by upper beam body 321, under Beading roller 307 is mounted in the mounting hole on 313 lower section side plate 315 of beading roller mounting groove by bearing support, passes through worm gear silk The height that bar elevator adjusts upper beading roller 306 can adjust the roller spacing of beading roller to adapt to the plate of different-thickness.
