Abstract
The utility model relates to a non-stop severing device for the production of tubes and other shaped sections, which belongs to the material processing machinery, which comprises mountings, bearings, gears, revolving axles, cutting tools, radial adjusting devices, and angle adjusting devices etc. The utility model is characterized in that: the transverse sections of shaped sections to be severed determine that the edged cutting tools are fixed on the rotation axes and rotate along. The axial line of the rotation axes forms an angle with the moving direction of the shaped sections ranging from 70 to 110 degrees. The cutting tools fulfill the severing task in the process of rotation with the rotation axes and complete the non-stop fixed-length severing of tubes and other shaped sections. The utility model has the advantage of low cost, simple operation, high productivity, little deformation of the tubes and shaped sections, which is in particularly to the severing of sections in the assembly lines of ornamentation pipes, capillary tubes, condensation tubes with plastic pipes, stainless pipes, copper pipes, band pipes, thick wall pipes, square pipes, rectangular pipes, elliptical pipes in the production line.
Description
Technical field
The utility model relates to a kind of section bar cutting machine.Belong to material processing machine.
Background technology
Existing section bar cutting machine is to cut when the section bar transfixion mostly.Even being arranged, some do not shut down shearing device at quantity-produced; known to the author's inspection information and investigation: also all be to take to follow cutting; being shearing device begins to quicken to follow the section bar rectilinear motion by static; when profile length arrives preseting length; shearing device and section bar synchronized movement are also cut; finish to be synchronized with the movement after finishing the cut-out task, the shearing device correcting action is finished one and is cut off circulation.
Obviously, the quantity-produced requirement is not satisfied in the actionless cutting of section bar, and productivity ratio is low.Can realize not shutting down cut-out though follow cutting, productivity ratio might be improved.But the raising of productivity ratio, be subjected to the acceleration of shearing device, at the uniform velocity, the influence of deceleration, static, reverse acceleration, the static reciprocating motion process of slowing down, ben is the tracking mechanism complexity, not only power consumption, and the difficulty and the cost height of system's control have limited its application to a great extent.
Summary of the invention
The purpose of this utility model is exactly the deficiency at existing equipment, and a kind of shearing device that remedies above defective is provided.
The utility model is mainly used in that tubing (also can be used for other section bar) produces does not shut down continuous cutting-off, and it comprises frame, bearing, gear, gyroaxis, cutter, guiding mechanism etc.Its main feature is by being determined the cutter of its cutting edge shape to be installed on the turning cylinder by cut type material cross section, rotating with turning cylinder.The axis of this turning cylinder becomes with the section bar direction of motion between 70 and 110 degree; cutter is finished cutting, is broken task by stretching tubing (or other section bar) when the rolling cut zone is to tubing (or other section bar) rolling cut in rotation process, and that realizes that as required preseting length carries out tubing (or other section bar) does not shut down customized cut-off.At the bottom of the structure of this device and simple to operate, the cost, the production efficiency height; The distortion of tubing (or other section bar) otch is little, is particularly suitable for the customized cut-off of tubing such as capillary, condenser pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part 1-frame; Part 2-cutter; Part 3-bearing; Part 4-turning cylinder; Part 5-guide mechanism; Part 6-angle-adjusting mechanism; Part 7-bevel gear; Part 8-is guiding mechanism radially; Other auxiliary component as shown in the figure.
The specific embodiment
Further specify the enforcement and the course of work of this device in conjunction with the accompanying drawings.
Part 2 cutters: when section bar was tubing, two cutting edge shape were semi arch up and down, and radius can be half that pipe internal diameter adds wall thickness, directly cut and break tubing.For other section bar, to cut off reliable cutting deformation little in order to make, the shape of Tool in Cutting sword should be similar to the section bar profile and the likelihood ratio less than 1 so that cutter cut the section bar entity in rotation process, make section bar connect the area minimizing and broken.
Part 3 bearings: standard component, support turning cylinder.
Part 4 turning cylinders: transferring power and motion, mounting cutter;
Part 5 guide mechanisms: promote guide wire with cylinder (not drawing among the figure), carry out the cutting of section bar and the switching of non-cutting position.
Part 6 angle-adjusting mechanisms: the double nut axial location, the axial location of adjusting gear carries out the adjustment of the relative angle of cutter.
Part 7 bevel gears: transferring power also determines the relative angle of cutter.
Part 8 is guiding mechanism radially: the screw-drive mechanism of jack panel with lock, adjust the radial position of cutter.
Turning cylinder drives cutter and rotates under the drive of rotary machine (not drawing in as motor figure).Helical gear on the turning cylinder is with power and move through on turning cylinder that another helical gear is delivered to another band cutter, and the cutter on the diaxon produces the rolling cut motion in process in relative rotation.When tubing (or other section bars) did not reach preseting length under the traction of production line traction machine, guide mechanism made tubing (or other section bars) be in non-off-position, as A place among the figure.Because not in Tool in Cutting sword movement locus, cutter is cut-in without ball when rolling.When tubing (or other section bars) reaches preseting length and cutter disengaging rolling cut zone, guide mechanism carries out the position and switches, tubing (or other section bars) is directed into B among off-position such as the figure from non-off-position, and after this Tool in Cutting sword is with rolling cut motion incision tubing (or other section bars) entity inside.Since the linear velocity of Tool in Cutting sword each point when cutting all greater than the linear velocity of section bar, so the cutter rake face produces pulling force, the climb cutting of similar milling process to tubing (or other section bars).Along with the carrying out of rolling cut motion, reduce gradually the entity coupling part of the tubing at Tool in Cutting sword place (or other section bars), and tension increases gradually, up to the tensile strength that surpasses material material is disconnected.When breaking away from the rolling cut zone on cutter, the guide mechanism switching that resets directs into non-off-position A place with tubing (or other section bars) from off-position B.So circulation.Radially the shape of guiding mechanism and Tool in Cutting sword determines residual 0 to break area.For tubing, the radius of Tool in Cutting sword circular arc adds half of wall thickness near pipe internal diameter, and two cutter smallest radial gaps are adjusted to 0.1 millimeter has a cut-out effect of feeling quite pleased with interior.The accurate adjustment of the relative angle of cutter can make the otch distortion reduce.The utility model can with such as: the customized cut-off of tubing (or other section bars) production line, coil section bar alignment customized cut-off production line etc. supporting, equipment such as relevant fixed long control system, straightener can be used auxiliary products, more in view of type, much more no longer technology maturation is stated.
