Description
Technical field
The present invention relates to a kind of pipe fitting cutting equipment, particularly a kind of corrugated pipe cut-off machine.
Background technology
Traditional pipe fitting cutting equipment mainly is comprised of the drive source of cutting knife and driving cutting knife, in cutting process, need to be by manually pipe fitting being implemented to carry, not only increased production cost, and in course of conveying, artificial conveyance easily makes pipe fitting to be cut shake, thereby causes and can't implement comparatively accurately cutting to pipe fitting; And the continuous cutting of this type of pipe fitting cutting equipment is relatively poor, and cutting process is comparatively loaded down with trivial details, and cutting efficiency is low.
And, bellows includes crest and trough, its crest is the part towards upper lobes, trough then is the part to lower recess, in process, owing to need to the distance of its length and pitch be controlled, at present, the pipe cutting machine on market and the data carries out customized cut-off to bellows, otch is sometimes at crest like this, sometimes at trough, be difficult to accurate to it and orientation amputate position, especially when otch during at trough, the mouth of pipe hangs for a long time to the bellows interior surfaces of wires, easily gall the insulating barrier on electric wire surface, make wire short-circuiting, can cause more serious consequence.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of cutting efficiency high, accurately cut bellows crest, the fast corrugated pipe cut-off machine of cutting speed.
For achieving the above object, the invention provides following technical scheme: a kind of corrugated pipe cut-off machine, include conveying device, the crest cut-off rest device that is connected with conveying device and the longitudinally cutting device that is connected with crest cut-off rest device, described conveying device includes the upper pressure wheel group, arrange press down wheels and drive the motor of each press nips corresponding to the upper pressure wheel group, described upper pressure wheel group and press down wheels and include at least two rollers that be arranged in parallel, link by belt between each roller, and one of them roller passes through motor-driven, described upper pressure wheel group and lower pressure wheel group are installed on respectively on the relatively independent axial location adjustable plate, each axial location adjustable plate is installed on respectively can be along on the guide pillar of its axial slip, and is provided with between each axial location adjustable plate and consists of each axial location adjustable plate axially is reverse movement along guide pillar link gear; Described crest cut-off rest device includes the bellows output fixture of the main shaft of rotation, the rotary head that is sheathed on the ring-type on the main shaft, the setting of corresponding rotation cutterhead, described rotary head is provided with one group at least towards the cutting blade assembly of the past polyslip in rotary head middle part and the pushing mechanism of driving cutting blade assembly slippage on the end face of bellows output fixture, described bellows output fixture place is provided with crest location testing agency, the setting corresponding to the axial location adjustable plate of described bellows output fixture; Described longitudinally cutting device includes the cutting positioning seat, is located at the cutter that cut on the positioning seat and the drive motors that drives cutting blade, cutting positioning seat and drive motors are vertical setting, be provided with the putting hole of ring-type in the described cutting positioning seat, the blade standing groove that the outer wall of cutting positioning seat is provided with putting hole conducting inner with it and places for cutter, the knife edge of cutter is in the medium position of putting hole in the cutting positioning seat, described main shaft inside is provided with transfer passage, this transfer passage and the corresponding linking of cutting positioning seat.
Adopt technique scheme, cutting efficiency is high, accurately cut the bellows crest, cutting speed is fast; Roller in each press nips links by belt, and pipe fitting is in course of conveying, and the outer peripheral face of pipe fitting contacts with belt, can directly not press to touch with pipe fitting and causes pipe fitting to cave in and break owing to roller; And each roller only needs one of them roller by motor-driven by after the belt interlock, and is easy to operate, avoided installing the required loaded down with trivial details debug process of synchronous motor; Each press nips is installed on respectively on the relatively independent axial location adjustable plate, and each axial location adjustable plate can be by link gear with the guide pillar axial slip, after arranging like this, upper pressure wheel group and the position adjustments that presses down between the wheels just can be implemented the adjusting of axial location installing plate by link gear, by the adjusting to position between each press nips, with this conveying that adapts to the different tube diameters pipe fitting, enlarged its versatility.Bellows by the output of bellows output fixture detects by the optocoupler detector, when the crest of bellows walks to the cutting blade assembly place of rotary head, the rotation of main shaft drives rotary head, because type and the diameter of bellows are different, the degree of depth of blade cuts is also with regard to different (being that blade is in the slippage stroke on the rotary head), blade on the rotary head is promoted by pushing mechanism, after arranging like this, owing to adopting high-precision optocoupler detector that the crest location of bellows is detected, guaranteed that position that blade cuts is at the crest location of bellows, the situation of trough can not appear cutting, and for the bellows of different-diameter, blade just can solve by the slippage that is in rotary head, has increased cut coverage; By the swivelling tool-holder circumgyration incision, guaranteed the smooth smooth of bellows otch, prevent that otch and internal wire from hanging, and improved security.The bellows of needs cutting is positioned in the putting hole of cutting positioning seat, then start drive motors, drive motors is linkage cutting blade vertically cutting bellows just, because the knife edge of cutting blade is in the middle part of standing groove, so bellows can be cut but not cut off, so not only process velocity is fast, and production efficiency also is improved.
The present invention further is set to: described upper pressure wheel group and lower pressure wheel group include respectively two rollers, be provided with between two rollers and be corresponding two auxiliary pressing wheels that arrange, the axial location adjustable plate is provided with two, two axial position adjustments plates are connected with guide pillar by guide pin bushing, described link gear includes to be located between the two axial position adjustments plates and the tooth bar that is connected with two axial position adjustments plates, with tooth bar engagement and be the gear of position rotating, be installed on the cylinder on one of them axial location adjustable plate, be provided with the tooth bar of two correspondences between the described two axial position adjustments plates, be provided with support column between two tooth bars, described gear is installed on this support column and with two tooth bars and meshes, two axial position adjustments plates are respectively upper axial position adjustments plate and lower shaft to the position adjustments plate, described cylinder and upper axial position adjustments plate are fixed, and the piston rod of cylinder and support column are to conflict and cooperate.
Adopt technique scheme, by driving cylinder, because an end of cylinder and support column are conflicted, thereby consist of the movement of cylinder self, drive upper axial position adjustments plate when cylinder moves and move, simultaneously, being relative direction by the rotation of gear between it with upper axial position adjustments plate to the position adjustments plate with lower shaft that upper axial position adjustments plate is connected by tooth bar moves, thereby consist of the adjusting of position between each press nips, easy to operate, simple in structure.
