Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment furnace accessories, in particular to a heat treatment furnace gasket material rack. Background Art

[0002] Heat treatment muffle furnace is a high temperature vacuum equipment, usually used for high temperature treatment, tempering treatment, heat treatment and other processes. There are three main heating methods of muffle furnace:

[0003] 1. Radiant heating: Radiant heating refers to the use of electric heaters or other radiation sources to directly transfer energy to the heated object through electromagnetic waves, so that the heated object produces a thermal effect; 2. Convection heating: Convection heating refers to a method of heat transfer through a heat conduction fluid. In a muffle furnace, an inert gas (such as argon) is injected into the furnace to make the gas flow and form convection, thereby heating the heated object; 3. Conduction heating: Conduction heating refers to a method of heat transfer to an object using thermal conductivity. In a muffle furnace, the heating body is directly brought into contact with the heated object, so that heat transfer occurs between the two, thereby achieving heating of the heated object;

[0004] In actual use of existing convection heating muffle furnaces, the objects to be heated are generally stacked directly in the heating furnace of the muffle furnace. Such stacking of workpieces will result in uneven heating of the bottom and top surfaces, affecting the heat treatment effect of the workpieces and reducing the heat treatment quality.

[0011] Preferably, the bottom plate, middle plate, upper plate and separation gasket are all made of high temperature resistant metal material.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The layer plate structure design of the utility model can effectively separate the two stacked workpieces up and down, so that the top and bottom surfaces of the two stacked workpieces will not be stacked and contacted, thereby effectively improving the heat treatment effect of the heat treatment furnace, improving the heating uniformity between the top and bottom surfaces, and having better performance;

[0014] The separators can be dynamically increased or decreased according to the actual size of the heat-treated product. In actual use, the space pattern between the layers can be changed by dynamically increasing or decreasing the number of separators, so that workpieces of different sizes can be placed for heat treatment. It has good practicality, simple overall structure and convenient use.

[0015] By arranging a plurality of honeycomb holes on the separation gasket, when the convective inert heating gas is blown onto the separation gasket, part of the convective gas can enter the outer wall of the workpiece through the honeycomb holes in the middle, and the excess heating gas flows toward both sides of the separation gasket for flattening, and then enters through the honeycomb holes on the side.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-5, the utility model provides an embodiment: a heat treatment furnace gasket material rack, including a bottom plate 1, a middle plate 2 and an upper plate 3, the bottom plate 1, the middle plate 2 and the upper plate 3 have the same structural dimensions, the bottom plate 1, the middle plate 2 and the upper plate 3 are arranged linearly with equal spacing from bottom to top, and the two sides of two adjacent layer plates are fixedly connected by side connecting columns 4, so that the bottom plate 1, the middle plate 2 and the upper plate 3 and the side connecting columns 4 can form a material rack for placing workpiece products, and the structural design of the layer plate can effectively separate the two stacked workpieces up and down, so that the top and bottom surfaces of the two stacked workpieces will not be stacked and contacted, thereby effectively improving the heat treatment effect of the heat treatment furnace, improving the uniformity of heating, and having better performance;

[0026] The bottom plate 1, the middle plate 2 and the upper plate 3 are provided with a plurality of strip slots 5 at the upper and lower ends, and a separation gasket 6 is provided between the strip slots 5 between two layer plates;

[0027] In order to ensure the high temperature resistance of each layer plate and the separator 6 and ensure the normal service life, the bottom plate 1, the middle plate 2, the upper plate 3 and the separator 6 are all made of high temperature resistant metal materials;

[0028] Positioning strips 7 are fixedly installed at the upper and lower ends of the separation gasket 6, and the separation gasket 6 is slidably connected to the strip-shaped slot 5 between the two layer boards through the positioning strips 7;

[0029] This structural design can separate two small workpieces for use by using the separation gasket 6, which can effectively improve the independence of heat treatment and the heating effect in actual use;

[0030] Moreover, the dividing gaskets 6 can be dynamically increased or decreased according to the actual size of the heat-treated product. When the heat-treated workpiece is large, all the dividing gaskets 6 between the single layers can be pulled out, thereby freeing up the placement space of the layers, so that the larger workpiece can independently occupy a layer of the layer structure. In actual use, the purpose of changing the spatial pattern between the layers can be achieved by dynamically increasing or decreasing the number of dividing gaskets 6, so that it can be suitable for the placement and use of workpieces of different sizes for heat treatment processing, has good practicality, and the overall structure is simple and easy to use.

[0031] In this embodiment, in order to improve the convection uniformity of the separation gasket 6, a plurality of honeycomb holes 8 with equal spacing and linear distribution are opened on the outer wall of the separation gasket 6;

[0032] When the convective inert heating gas blows onto the separation gasket 6, part of the convective gas can enter the outer wall of the workpiece through the honeycomb hole 8 in the middle. Due to the aperture size flux problem of the honeycomb hole 8, the gas flow rate is fixed within a certain period of time, so the excess heating gas flows to the two sides of the separation gasket 6 for flattening, and then enters through the honeycomb hole 8 on the side. In this way, the separation and flattening of the separation gasket 6 can effectively improve the heating uniformity of the workpiece, increase the heat treatment effect of the furnace body, and have better performance.

[0033] Furthermore, in order to improve the smoothness of the separation gasket 6 during insertion and reduce resistance, a ball 9 is installed inside the positioning strip 7 at the top. The set ball 9 can change the sliding friction insertion method to rolling friction, thereby facilitating the improvement of the smoothness of the separation gasket 6 during extraction and insertion, and improving the use effect of the structure.

[0034] In this embodiment, in order to ensure normal air convection and ventilation performance between each layer board, ventilation holes 10 are opened on both sides of the bottom layer board 1, the middle layer board 2 and the upper layer board 3, and square grooves 11 are provided on the bottom layer board 1, the middle layer board 2 and the upper layer board 3.

[0035] In this embodiment, in order to facilitate the delivery or removal of the material rack of the utility model, two groups of symmetrically arranged handles 12 are fixedly installed on the side connecting columns 4 on the outside between the middle plate 2 and the upper plate 3, and the arranged handles 12 can be used for hand-held delivery or removal.

[0036] Working principle: When the material rack of the utility model is used, the material rack can be placed into the heating furnace of the muffle furnace through the handle 12. After being placed, the workpiece product that needs to be heat treated is placed between each layer plate or separation gasket 6, so as to complete the heat treatment process of the workpiece;

[0037] The utility model is provided with a plurality of layer plate structures. The structural design of the layer plates can effectively separate the two stacked workpieces up and down, so that the top surface and the bottom surface of the two stacked workpieces will not be stacked and contacted, thereby effectively improving the heat treatment effect of the heat treatment furnace, improving the heating uniformity between the top surface and the bottom surface, and having better use performance;

[0038] At the same time, by providing a separation gasket 6, when the convective inert heating gas blows onto the separation gasket 6, part of the convective gas can enter the outer wall of the workpiece through the honeycomb hole 8 in the middle. Due to the aperture size flux problem of the honeycomb hole 8, the gas flow rate is fixed within a certain period of time, so the excess heating gas flows to the two sides of the separation gasket 6 for flattening, and then enters through the honeycomb hole 8 on the side. In this way, the separation and flattening of the separation gasket 6 can effectively improve the uniformity of the side heating of the workpiece, increase the heat treatment effect of the furnace body, and have better performance.

[0039] By using the layer plate and the separation gasket 6 in combination, the heating effect of the top surface, bottom surface and side surface of the workpiece can be effectively improved, and the workpiece has a uniform heating performance;

[0040] Moreover, the separation gaskets 6 can be dynamically increased or decreased according to the actual size of the heat-treated product. When the heat-treated workpiece is large, all the separation gaskets 6 between a single layer can be pulled out, thereby freeing up the placement space of the layer and maximizing the placement space. At this time, the larger workpiece can independently occupy a layer of the layer structure. In actual use, the purpose of changing the spatial pattern between the layers can be achieved by dynamically increasing or decreasing the number of separation gaskets 6. This can be used for heat-treatment processing and placement of workpieces of different sizes. It has good practicality, and the overall structure is simple and easy to use.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
