Description

Heating structure for 3D printing

Technical Field

The utility model relates to a printer equipment technical field, especially a heating structure that 3D printed.

Background

3D printing technology, also known as "rapid prototyping technology", was emerging in the 80's of the 20 th century. The method has the greatest advantage that any object can be generated directly from the graphic data designed by the computer without mechanical processing or grinding tools, thereby greatly shortening the development period of products, improving the productivity and reducing the production cost. And thus is widely used in the art and industry. The 3D printing technology can be classified into a Stereo Lithography (SLA), a laminate solid fabrication (LOM), a Selective Laser Sintering (SLS), a Fused Deposition Modeling (FDM), and the like according to a molding method thereof. The FDM rapid prototyping system is the most essential difference from other systems in that it does not use a laser system, and therefore is the lowest cost and is currently the most widely used 3D printing technique.

In 3D printing technology, a heating thermostat is often used, i.e. a part is heated and kept at a constant temperature. Conventionally, in order to improve the heating efficiency, a heating pipe is generally used to heat a component, and after the target temperature is reached, the heating is stopped, and after the heating is stopped, the temperature is decreased, so that the temperature of the component always fluctuates within a range of values, and thus the heating pipe cannot be always maintained at a certain constant value.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's shortcoming, provide a heating structure that 3D printed.

The purpose of the utility model is realized through the following technical scheme:

the utility model provides a heating structure that 3D printed, includes two relative settings and fixed connection's heat transfer cover, every the heat transfer cover is including the cover body, one side of the cover body is opened along its length direction has interior mounting hole, interior mounting hole is semi-circular hole, the opposite side of the cover body is provided with refrigeration piece installation face, it has a plurality of heating pipe mounting holes that link up to open along the axial of interior mounting hole on the terminal surface of the cover body, wear to be equipped with the heating pipe in the heating pipe mounting hole, be fixed with the refrigeration piece on the refrigeration piece installation face, the one side that the refrigeration piece was kept away from refrigeration piece installation face is installed the water-cooling tank.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 and fig. 2, a heating structure for 3D printing includes two heat transfer sleeves 1 disposed opposite to each other and fixedly connected to each other, each heat transfer sleeve 1 includes a sleeve body 1a, one side of the sleeve body 1a is provided with an inner mounting hole 1b along the length direction thereof, the inner mounting hole 1b is a semicircular hole, and a whole circle is formed after the two semicircular holes are oppositely arranged, which is used for fixing a workpiece, the other side of the sleeve body 1a is provided with a refrigerating sheet mounting surface 1d, preferably, two convex edges are arranged on two sides of the refrigerating sheet mounting surface 1d and used for positioning the refrigerating sheet 2, a plurality of through heating pipe mounting holes 1c are formed on the end surface of the sleeve body 1a along the axial direction of the inner mounting hole 1b, the heating pipe 4 penetrates through the heating pipe mounting hole 1c, the refrigerating sheet 2 is fixed on the refrigerating sheet mounting surface 1d, and the water cooling tank 3 is mounted on one surface, away from the refrigerating sheet mounting surface 1d, of the refrigerating sheet 2. After the workpiece is fixed, the heating pipe 4 is firstly used for heating during working, the temperature quickly reaches the vicinity of the target temperature (but the target temperature is not reached), the heating of the heating pipe 4 is stopped at the moment, the refrigerating sheet 2 is used for continuing heating, and after the target temperature is reached, the heating power and the refrigerating power of the refrigerating sheet 2 are controlled, so that the temperature of the workpiece can be kept in a constant state.

Further, a screw hole 1e is formed in the side wall of each sleeve body 1a, a screw penetrates through the screw hole 1e and is locked and fixed to form a detachable structure, so that a workpiece is mounted more conveniently, and the workpiece can be taken out or put in only by dismounting the screw.

Further, the heat transfer sleeve 1 is made of brass material, so that the heat transfer efficiency is improved.

Furthermore, the refrigerating plate 2 is a semiconductor ceramic refrigerating plate which is divided into two surfaces AB, when the conducting wire is in positive connection, the surface A is used for refrigerating, the surface B is used for heating, and when the conducting wire is in reverse connection, the surface A is used for heating, and the surface B is used for refrigerating. When the surface far away from the refrigerating sheet mounting surface 1d heats, the water cooling box 3 dissipates heat to prevent the refrigerating sheet 2 from being burnt.

The working process of the utility model is as follows: the heat transfer sleeve 1 made of brass material can improve the heat transfer efficiency by sleeving the components to be heated and thermostated in the inner mounting hole 1 b. When the temperature rises, the heating pipe 4 is used for quickly heating to enable the temperature of the workpiece to reach the vicinity of the target temperature, then the heating pipe 4 stops supplying heat, the refrigerating sheet 2 starts to heat to enable the temperature of the workpiece to reach the target temperature, and after the target temperature is reached, the temperature of the workpiece can be kept constant only by controlling the heating power and the refrigerating power of the refrigerating sheet 2. The heating and cooling of the cooling fins 2 are prior art, and the control principle thereof is not described herein.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
