Abstract

The invention relates to an electric heating element (1) formed by a pipe (2) with a longitudinal slit, and provided with a bendable heating body (3). The heating body is installed on a housing layer; the pipe (2) can be clamped by a clamping device (5) to a to-be-heated body; a recessed pit (6) is formed in the housing layer of the heating body to form the clamping device (5); the recessed pit covers teh longitudinal slit (10); a sliding plate (7) is movably arranged in the recessed pit along the heating element (1); the bottom surface of the sliding plate opposite to the recessed pit (6) returns behind an alinging line of the housing layer; projections (8) inserted into window-shaped notches (9) are formed on two sides of the longitudinal slit (10) in the recessed pit (6); the projections are matched wtih longitudinal ridges of the notches (9), so the sliding plate (7) enables the heating body (1) to be fastened on the to-be-heated object.

Description

technical field [0001] The invention relates to an electric heating element for heating cylindrical or tubular objects, in particular for nozzles of plastic or metal casting equipment or injection molding equipment, wherein the heating element is composed of partially or completely longitudinally opened narrow slotted tubes, or shell plates bent into a tubular shape forming or having partial or entire longitudinal slits, or composed of a plurality of bent shell plates assembled into a tubular shape, the heating element has at least one bendable An electric heating body having a shell and at least one heat conductor arranged insulatively in an insulating material filling of the shell, wherein the heating body is mounted on the shell of the tube or is preferably inserted or pressed into Into the receiving groove on the shell of the tube or the shell plate, wherein the tube or the shell plate bent into a tubular shape can be clamped relative to the object to be heated by means of...
