Abstract

The utility model relates to a device adopting heating blade to incise which is adapted to plastic pipe automatic production line. The utility model consists essentially of a moving sliding plate, a block, a spring, a safety cover and an incision body in the safety cover, wherein the incision body is composed of a cutter frame with grooves, a moving cutter plate, a blade, a heating plate, a fixing adjustment plate, a rotating iron plate, an axletree and a cylinder. The cutter frame is fixed on the moving sliding plate vertically; the blade is fixed at the bottom of the moving cutter plate; the moving cutter plate traverses the cutter plate groove and is in the lever connection with the cylinder through the rotating iron plate; the heating plate is arranged between the blade and the fixing adjustment plate; the blade surface contacts with the heating plate surface; the heating plate is fixed on the fixing adjustment plate; the fixing adjustment plate is fixed on the cutter frame. The blade obtains stronger force by lever connection; the blade can rise to a certain temperature by heating plate, thereby reducing friction between blade and pipes and lengthening service life of the blade. The device has rapid incision speed and it does not cause fins and burr, thereby reducing waste of raw materials and reducing reprocessing procedures of production workers.

Description

Blade heat is cut device

Affiliated technical field

The utility model relates to a kind of employing device that blade cuts of heating, and is applied on the plastic pipe automatic assembly line.

Background technology

At present, the plastic pipe automatic assembly line adopts the circular saw bit cutter sweep, thereby mainly rotate at a high speed tubing is carried out sawing by the driven by motor circular saw, the active force that utilizes cylinder to produce is controlled the motion of circular saw and whole device, because circular saw blade causes and produce a large amount of sawdusts, burr and burr in cutting process.

Summary of the invention

In order to overcome circular saw produces a large amount of sawdusts, burr and burr in cutting process deficiency, the utility model provides a kind of blade heat to cut device, and this installs, and not only cutting speed is fast, and does not have burr, burr in the cutting process.

The technical scheme that its technical problem that solves the utility model adopts is: the utility model mainly comprises moving slide board, pulley, spring, safety guard and the cutting main body in safety guard, the cutting main body comprises the knife plate frame of trough of belt, movable knife plate, blade, heating plate, the secured adjusted plate, rotate iron plate, bearing, cylinder, in safety guard, the knife plate frame is vertically fixed on the moving slide board, the parallel movable knife plate bottom that is fixed on of blade, movable knife plate passes the knife plate groove to carry out lever with cylinder by rotation iron plate and is connected, fulcrum is located on the fixing bearing of knife plate frame, be provided with heating plate between blade and secured adjusted plate, blade face contacts with heater plate surface, heating plate is fixed on the secured adjusted plate, the secured adjusted plate is fixed on the knife plate frame, when travel switch sends signal, cylinder produces pressure and drives rotation iron plate to the downward active force of movable knife plate, when blade contacts with tubing, cutter sweep and tubing are synchronized with the movement, the blade that heating rises to uniform temperature cuts off tubing rapidly under active force, multiple air return cylinder is opened movable knife plate is moved upward, and cutter sweep is got back to original position under the active force of spring.Make blade obtain bigger active force by adopting lever to connect, adopt heating plate to make blade be raised to certain temperature, thereby reduce the friction of blade and tubing, prolong the life-span of blade.This installs, and not only cutting speed is fast, and can not produce burr, burr in the cutting process.

The beneficial effects of the utility model are: cost is low, power consumption less, cutting speed is fast, do not produce burr, burr in the cutting process, not only reduced wastage of material, and reduced direct labor's rework process.
