Abstract

The invention relates to the related technical field of sectional material equipment in particular to a hot cutting machine for sectional materials. The hot cutting machine comprises a machine frame and a cutting device arranged on the machine frame, wherein the cutting device comprises a horizontally arranged cutting platform; a movable knife frame which moves vertically is arranged above the cutting platform; the movable knife frame is provided with a cutting knife blade which moves along with the movable knife frame; and a heating mechanism parallel to the cutting knife blade is also arranged above the cutting platform. The hot cutting machine for the sectional materials has the advantages of simple structure, reliable cutting performance, easy electric control, convenience for operation, simpleness and safeness, ideal man-machine interface, large processing range and no noise, moreover, the online automation of the hot cutting machine is realized by adopting a PLC (Programmable Logic Controller).

Description

A kind of section bar hot-cutting machine

Technical field

The present invention relates to section bar equipment correlative technology field, particularly a kind of section bar hot-cutting machine.

Background technology

The mode of at present domestic PVC plastic material cutting is the saw blade cutting; Produce certain bits, dust in the cutting process; Though all adopting the dust catcher Integrated Chip on the machine collects; But be to use the sealing of dust catcher requirement cutting part could reach satisfied effect well; Rotate the very big noise that can't reduce of generation at cutting process at a high speed owing to saw blade simultaneously, also will often recycle dust and change dust collecting sleeve, giving makes troubles in the production and production environment is produced pollution exerts an influence with long-term field worker health.

Summary of the invention

The present invention provides a kind of section bar hot-cutting machine, can't reduce the technical problem of noise when solving the cutting that prior art exists.

The technical scheme that adopts is following:

A kind of section bar hot-cutting machine; Comprise frame and be arranged on the cutter sweep on the frame; Said cutter sweep comprises the Cutting platform of horizontal positioned; Above Cutting platform, be provided with the follow rest that moves both vertically, follow rest is provided with the cutting blade with the moving frame motion, above Cutting platform, also is provided with the heating arrangements parallel with cutting blade.

Further, said heating arrangements comprises electric boiling plate and the cylinder that is connected with electric boiling plate.

Further, said cutting blade and Cutting platform have certain angle, and said angle is an acute angle.

Further, said cutter sweep also comprises and is arranged on follow rest the place ahead and the clamp parallel with follow rest.

Further, also comprise the elevating mechanism that moves up and down, said follow rest is fixedly installed on the elevating mechanism.

Further, said cutting blade one end is fixed, the other end be installed in slidably and the dovetail groove part that cooperates with follow rest on, on the said dovetail groove part preloading spring that is connected with the cutting blade other end is installed.

Further, said cutter sweep also comprise be installed in follow rest below near switch.

Further, also comprise rack-mounted follower.

The present invention is simple in structure, cutting performance is reliable, electric easy control, be convenient to operation, simple and safe, man-machine interface is desirable, adopts PLC to realize on-line automaticization of cutting machine, the big and noiselessness of the range of work.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed explanation.

As depicted in figs. 1 and 2, the present invention is a kind of section bar hot-cutting machine, comprises frame 2, is arranged on cutter sweep 3 and follower 1 on the frame 2.

Shown in Fig. 3 and 4, cutter sweep 3 comprises follow rest 4, goes up slip guide pillar 5, cutting blade 6, electric boiling plate 7, panel 8, mounting bracket 9, spring 10, screw 11, nut 12, roller 13, elevating mechanism 14, clamp 15, guide pillar 16, lower slider guide pillar 17, cylinder 18, near switch 19 and Cutting platform 20.Wherein, Cutting platform 20 horizontal positioned, follow rest 4 moves both vertically above Cutting platform 20, and cutting blade 6 is arranged on the follow rest and moves with moving frame 4, and electric boiling plate 7 laterally arranges with cutting blade 6.Follow rest 4 is fixedly installed on the elevating mechanism 14.Cutting blade 6 one ends are fixed, the other end be installed in slidably and the dovetail groove part that cooperates with follow rest on, the preloading spring 10 that is connected with cutting blade 6 other ends is installed on the dovetail groove part.Below follow rest 4, be provided with near switch 19.

Operation principle:

After cutter sweep 3 received cutoff signal, clamp 15 actions compressed institute's cut type material downwards; Drive elevating mechanism 14 entrys into service of cutting, make to be installed in the cutting blade 6 that has heated in advance on the follow rest 4 and to move down to cut and wear section bar; Behind the electrical control signal that receives near switch 19, elevating mechanism 14 counter-rotating cutting knifes are upwards return original position and are waited for cutting action next time; The mechanism of blade 6 heating simultaneously gets signal, and the action of cylinder 18 range-adjustables is pushed into electric boiling plate 7 and is attached on the cutting blade, and temperature control stopped heating automatically after blade 6 was heated to design temperature; Clamp 15 actions simultaneously upwards reset, and back and forth carry out cutting action in proper order.

Cutting blade 6 is installed in and has certain gradient on the follow rest 14; Can reduce contact-making surface during cutting, form cutter and reduce stressed the weighing wounded of material with institute cut type material for some contact and be out of shape by the hot material deliquescing, cutting blade 6 is affected by thermal expansion and contraction when heating, and institute cut type material cross section can not be an arc for straight line in the horizontal after the generation anamorphic stretching, for this reason; Cutting blade 6 installation and design are that an end is fixed; The other end is contained in the dovetail groove part that slidably cooperates with movable stand, and design and installation has preloading spring 10 on it, when cutting blade 6 adds thermal stretching; Automatically blade 6 is stretching under the effect of elastic force, guarantee that otch is a straight line; Perpendicularity in order to guarantee on the cut type material vertical direction is provided with slip guide pillar 5, and the knife rest movable stand 4 following elevating mechanisms 14 that connect are cut speed, moved up and down locality by the drive variable frequency Electric Machine Control; Electric boiling plate 7 be installed in can before and after, up and down also on the adjustable support of rotatable certain angle, guaranteeing to coincide electric boiling plate 7 and cutting blade 6, to be adjacent on even heating, the cutting blade 6 heating-up temperature the same, the assurance cut quality.
