Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
As shown in fig. 1 to 4, an embodiment of the invention discloses a heat insulation plate, which includes a heat insulation strip 1 and a metal section 2, wherein the heat insulation strip 1 is inserted into the metal section 2, a hole groove 3 is formed in an end surface of the heat insulation strip 1, which is in contact with the metal section 2, a glue line 4 is arranged in the hole groove 3, the glue line 4 contains magnetic powder, and the glue line 4 can be heated and melted under the action of electromagnetic induction and can bond the heat insulation strip 1 and the metal section 2. The principle of electromagnetic induction heating is that alternating current generated by a power supply generates an alternating magnetic field through an inductor, and a glue line 4 with magnetic powder is arranged in the inductor to cut alternating magnetic lines, so that alternating current (namely eddy current) is generated in the magnetic powder, the eddy current enables atoms in an object to move randomly at a high speed, and the atoms collide with each other and rub to generate heat energy, thereby playing a role in heating.
Further, the magnetic powder in the glue line 5 is made of a ferromagnetic substance. The ferromagnetic substance has the characteristic of Curie point temperature, and when the Curie point temperature is reached, the magnetism of the ferromagnetic substance disappears, so that the ferromagnetic substance can not be heated by electromagnetic induction any more, the upper limit of the temperature can be accurately controlled, and the damage to the whole structure caused by overhigh heating temperature is avoided.
In a possible embodiment, the magnetic powder is ferrite powder, which has lower cost and better Curie temperature range. The rubber thread 5 is made of a mixture of resin (such as polypropylene PP) and ferrite powder, and the thermoplastic resin can be softened after being heated, so that the rubber thread can better adapt to the shape of the tooth socket. The magnetic powder has a Curie point of not more than 180 ℃ at the most, and in practice it is usually preferred that it does not exceed 120 ℃ which ensures that the resin melts without affecting the rest of the profile.
In the aspect of the structure, the metal section bar 2 is provided with a notch 5, the heat insulation strip 1 comprises a strip head 6, the strip head 6 is inserted into the notch 5, and the hole groove 3 is formed in the end face of the strip head 6. The notch 5 comprises an outer chuck 7, a blocking wall 8 and a groove bottom 9, and the strip head 6 is clamped by the outer chuck 7 after rolling.
Corresponding to the heat insulation board, the invention also provides a processing technology, which comprises the following steps: a glue line containing magnetic powder is arranged in the hole groove of the heat insulation strip in a penetrating way; inserting the heat insulation strips into the metal section; rolling and compounding the metal section and the heat insulating strip; heating and melting the glue line through electromagnetic induction; and cooling the glue line until the glue line is solidified.
Compared with the spraying and heating method in the prior art, the processing technology has low realization difficulty, is easier to control the upper limit of the heating temperature, and has better processing quality.
In order to realize the processing technology, the invention also provides a processing device of the heat insulation plate, as shown in fig. 5, the processing device comprises a power supply 10, a coil 11 and a bearing table 12, wherein the power supply 10 supplies a variable current to the coil 11, and the bearing table 12 is used for bearing the heat insulation plate.
The power supply 10 may be an ac power supply, or may be a dc power supply connected to a frequency converter, as long as the current can be continuously changed.
Preferably, the susceptor 12 is disposed at the position of the axis of the coil 11 where the line density of magnetic induction is the greatest and thus the heating effect is the best. It should be noted that the carrier 12 is not strictly required to be located on the axis of the coil 11, but the carrier 12 is located near below the axis of the coil 11, so that the thermal insulation board is located at the center of the coil 11 when the thermal insulation board is placed on the carrier 12.
The existing heating equipment needs to heat the whole heat insulation plate, and the length of the heat insulation plate can reach several meters, so that the heating equipment is large in size and complex in structure. In order to reduce the volume of the equipment, the processing equipment provided by the invention can also be provided with a conveying device on the bearing table 12, such as a conveying belt with a motor, a chain wheel and the like. The conveying direction of the conveying device is parallel to the axial direction of the coil 11. The conveying device is used for slowly conveying the heat insulation board along the axial direction of the coil 11, so that the coil 11 can gradually heat all parts of the heat insulation board, the equipment does not need to be made into the same length as the whole section, and the volume of the equipment is greatly reduced.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosure is provided to enable any person skilled in the art to make or use the disclosure.
