Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, and more specifically, to a heat treatment device for metal materials. Background Technology

[0002] Heat treatment of metallic materials is a process that controls their properties by altering the microstructure of the surface or interior of a metallic material. Heat treatment does not change the shape or chemical composition of the workpiece, but it can significantly affect its mechanical properties, physical properties, and corrosion resistance.

[0003] Existing heat treatment equipment, such as the mechanical heat treatment furnace disclosed in CN210506452U, has a uniform heating rate throughout the furnace, avoiding problems such as cracking and deformation of processed parts due to uneven heating. It can also be adjusted and fixed according to the size of the workpiece, making it practical. However, this existing heat treatment furnace can only perform heat treatment operations on a single workpiece or material. For workpieces or materials that need to be mass-produced in actual production, the heat treatment efficiency is very low, and the long working time of the heat treatment furnace can also affect its service life, greatly increasing the processing cost.

[0008] Furthermore, one end of the transfer track is detachably connected to the feeding track, and the other end of the transfer track is detachably connected to the feed track. A limiting protrusion is provided on the limiting guide rail.

[0009] Furthermore, the feeding trolley includes a base, a telescopic structure, and a placement plate. The base is provided with multiple track wheels, and the track wheels are provided with guide grooves on their circumference. The limiting protrusion is fitted into the inside of the guide groove. The telescopic structure is installed between the base and the placement plate and is used to control the lifting and lowering movement of the placement plate. The material separating frame is detachably mounted on the placement plate.

[0010] Furthermore, the guide grooves are adapted to the feeding track, the limiting guide rail, and the infeed track, respectively.

[0011] Furthermore, the placement assembly includes multiple stacked groups arranged vertically and horizontally by spacers, each stacked group having multiple placement boxes, and each placement box having a placement space for placing metal materials.

[0012] Furthermore, a cavity is formed inside the heating furnace, and a feed inlet communicating with the cavity is opened on one side of the heating furnace. The feed track is set at the bottom of the feed inlet, and a heating chamber and a positioning chamber are arranged vertically and vertically inside the cavity through a partition.

[0013] Furthermore, a sealing door is hinged to the heating furnace, and multiple heating rods are inserted into the inner wall of the sealing door. The multiple heating rods are arranged at intervals between each other, and the sealing door covers the heating chamber and cooperates to form a heating space.

[0014] Furthermore, the heating rod includes a heating wire, a core layer, and a covering layer. The heating wire is spirally wound around the core layer, and the covering layer is sleeved on the outside of the core layer.

[0015] Furthermore, a plurality of heat dissipation perforated plates are evenly laid on the outer wall of the heating furnace. Attached Figure Description

[0024] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0025] like Figure 1 and Figure 2 As shown, a metal material heat treatment device according to one embodiment of the present invention includes a feeding device and a heating device. The feeding device includes a feeding cart 1, a feeding track 2, and a separating frame 3. The feeding cart 1 is slidably mounted on the feeding track 2. The separating frame 3 is mounted on the feeding cart 1 and can be raised and lowered relative to the feeding track 2. The separating frame 3 is provided with multiple placement components 4. The heating device includes a heating furnace 5 and a feeding track 6 flush with the feeding track 2. The heating furnace 5 is provided with a heating chamber and a positioning chamber spaced vertically by a partition 51. Multiple heating rods 52 are inserted into the inner wall of the heating chamber. The feeding track 6 is installed at the bottom of the positioning chamber. The top of the separating frame 3 abuts against the bottom of the partition 51.

[0026] The aforementioned metal material heat treatment equipment, by being equipped with a feeding cart 1, facilitates the transportation of metal materials, improving production efficiency and safety; by being equipped with multiple placement components 4, it facilitates the placement and storage of multiple metal materials, thereby enabling simultaneous heat treatment of multiple metal materials, improving heat treatment efficiency, and reducing production costs; by being equipped with heating rods 52, heat energy is generated through the resistance heating effect, causing the temperature inside the heating furnace 5 to rise uniformly, ensuring that the temperature inside the heating furnace 5 reaches the required process conditions, thus meeting the needs of heat treatment operations; by being equipped with partitions 51, it is beneficial to position the feeding cart 1 and prevent the feeding cart 1 from shifting, so that the partition frame 3 can separate the heating chamber and the positioning chamber, and thus, during processing, the metal materials in the placement components 4 can be placed in the heating space inside the heating chamber.

[0027] Specifically, both the feeding track 2 and the feed track 6 are set in a horizontal direction.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the metal material heat treatment equipment further includes a transfer device disposed between the feeding device and the heating device. The transfer device includes a transfer track 7 and a transfer cart 8 slidably mounted on the transfer track 7. A limiting guide rail 81 flush with the feeding track 2 is fixedly disposed on the top of the transfer cart 8.

[0029] Specifically, the transfer track 7 is set horizontally and perpendicular to the feed track 2.

[0030] Furthermore, the limiting guide rail 81 is located on the extension line of the feeding rail 2. This facilitates the direct transfer of the feeding car 1 to the transfer car 8 on the transfer rail 7.

[0031] like Figure 2 As shown, in one embodiment, one end of the transfer track 7 is detachably connected to the feeding track 2, and the other end of the transfer track 7 is detachably connected to the infeed track 6. A limiting protrusion 82 is provided on the limiting guide rail 81. The transfer track 7 and the feeding track 2, as well as the transfer track 7 and the infeed track 6, can be disassembled and assembled at any time, which facilitates the adjustment of the conveying position and conveying distance, thereby adapting to different production site spaces.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding cart 1 includes a base 11, a telescopic structure 12, and a placement plate 13. The base 11 is equipped with multiple track wheels 14, each track wheel 14 having a guide groove 141 extending circumferentially. A limiting protrusion 82 engages with the guide groove 141. The telescopic structure 12 is installed between the base 11 and the placement plate 13 and is used to control the lifting and lowering movement of the placement plate 13. The material separating frame 3 is detachably mounted on the placement plate 13. The limiting protrusion 82 engages with the guide groove 141, thereby limiting the feeding cart 1 and preventing it from falling off the limiting guide rail 81, which would affect transportation efficiency.

[0033] The telescopic structure 12 is preferably a lifting platform, which is existing technology and will not be described in detail. When different sizes of heating furnaces 5 are used during processing, the degree of lifting of the telescopic structure 12 on the placement plate 13 can be adjusted according to the size or height of the heating furnace 5, so as to complete the positioning of the placement component 4 and facilitate better completion of heat treatment processing operations.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the guide groove 141 is adapted to the feeding track 2, the limiting guide rail 81, and the infeed track 6, respectively. This allows the feeding cart 1 to reciprocate between the feeding track 2, the limiting guide rail 81, and the infeed track 6, ensuring the round-trip transportation of the feeding cart 1.

[0035] In one embodiment, the placement component 4 includes multiple stacked groups arranged vertically by spacers, each stacked group having multiple placement boxes 41, and each placement box 41 having a placement space for placing metal materials.

[0036] In one embodiment, a cavity is formed inside the heating furnace 5, and a feed inlet communicating with the cavity is opened on one side of the heating furnace 5. The feed track 6 is set at the bottom of the feed inlet, and a heating chamber and a positioning chamber are arranged vertically and vertically through a partition 51 inside the cavity.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, a sealing door 53 is hinged to the heating furnace 5, and a plurality of heating rods 52 are inserted into the inner wall of the sealing door 53. The plurality of heating rods 52 are arranged at intervals between the upper and lower parts, and the sealing door 53 covers the heating chamber and cooperates to form a heating space.

[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the heating rod 52 includes a heating wire 521, a core layer 522, and a covering layer 523. The heating wire 521 is spirally wound around the core layer 522, and the covering layer 523 is sleeved on the outside of the core layer 522. The heating wire 521 is preferably a common nickel-chromium heating wire. With the supply of power, heat can be generated on the high-resistance heating wire to achieve the purpose of heating or temperature control.

[0039] Preferably, both the core layer 522 and the covering layer 523 are heat-resistant fiber layers.

[0040] In one embodiment, a plurality of heat dissipation perforated plates 54 are evenly distributed on the outer wall of the heating furnace 5. This increases the area for air circulation, allowing air to flow more smoothly over the outer wall surface of the furnace, which is beneficial for improving the heat dissipation effect of the furnace after heat treatment.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
