Description

Technical Field

[0001] This utility model relates to the technical field of trolley tempering furnace devices, specifically a temperature-controlled zoned trolley tempering furnace. Background Technology

[0002] A quenching and tempering furnace is a furnace used in a combined heat treatment process of quenching and tempering steel or steel parts. A trolley-type quenching and tempering furnace is a type of equipment used for metal heat treatment, mainly for improving the mechanical and physical properties of metals. Steel that has undergone quenching and tempering is called quenched and tempered steel, which generally refers to medium carbon steel with a carbon content of 0.3-0.6%. Parts made of this type of steel are generally required to have excellent comprehensive mechanical properties, that is, while maintaining high strength, they also have good plasticity and toughness. People often use quenching and tempering to achieve this purpose, so people are used to call this type of steel quenched and tempered steel. Quenched and tempered steel is widely used in structural parts of various machines and is the most widely used type of structural steel.

[0003] Currently, most bogie-type tempering furnaces are used individually with a uniform internal quenching space, ensuring consistent temperature diffusion and similar quenching degrees during quenching. However, different metals require different temperatures for heat treatment, and operating them individually reduces efficiency and results in poor operational continuity. Therefore, improvements to the equipment are needed. The innovation lies in creating different temperature zones within the same furnace, allowing materials requiring different heat treatment temperatures to be quenched separately to complete the heat treatment operation. Utility Model Content

[0004] The purpose of this invention is to provide a temperature-controlled zoned bogie tempering furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature-controlled zoned trolley tempering furnace, comprising a central furnace body, a movable frame installed at the front end of the central furnace body, and a recessed groove provided on the surface of the movable frame, a closing plate assembled between the movable frames, a conveying pipe installed at the upper end of the central furnace body, and a transmission pipeline assembled beside the conveying pipe, a support end assembled at the bottom of the central furnace body, a friction plate installed on the lower surface of the support end, and a control system installed at the rear end of the central furnace body, with a display panel installed on the surface of the control system.

[0006] Preferably, a tensioning mechanism is installed at the upper end of the movable frame, and the surface of the tensioning mechanism is provided with a tensioning port, at which a tensioning chain is assembled.

[0007] Preferably, the interior of the central furnace body is provided with a quenching layer, and the bottom surface of the quenching layer is provided with an engagement groove, on which a plate is installed.

[0008] Preferably, the bottom of the placement plate is equipped with rollers, and the surface of the control system is equipped with telescopic columns, which are connected to the surface of the placement plate.

[0009] Preferably, the inner surface of the quenching layer is provided with a side groove, and several heating elements are assembled inside the side groove, and partition blocks are installed inside the quenching layer.

[0010] Preferably, the surface of the placement plate is fitted with a mating block.

[0011] Preferably, a snap-fit ​​plate is mounted on the surface of the closing plate, and the snap-fit ​​plate engages with the extension chain.

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

[0013] 1. Compared with other bogie tempering furnaces, this device mainly has partitions inside the bogie tempering furnace. The partitions are combined with the meshing plates mounted on the surface of the loading plate to divide the internal space into three parts. The number of heating elements in each different space is different, resulting in different internal temperatures. In addition, the meshing plates and partitions are designed to be thicker, providing good insulation, which can not only ensure the maintenance of the internal temperature of each part, but also prevent the temperature from alternating between the two zones.

[0014] 2. In addition, this device is simple and ingenious in design, and its operation is mainly controlled by the back-end control system. The internal design is simple, and the structures are highly compatible with each other, making it convenient in terms of operation and subsequent maintenance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] refer to Figure 1 , 2 The main body is a central furnace body 1, which is designed as a square. A movable frame 7 is installed at the front end of the central furnace body 1. The movable frame 7 is welded to one side surface of the central furnace body 1, which is the direction in which the opening of the central furnace body 1 faces. The surface of the movable frame 7 has a recessed groove, and a toothed chain is installed at the bottom inside the recessed groove. A closing plate 6 is assembled between the movable frames 7. A live shaft gear is assembled on the side surface of the closing plate 6 to ensure that the live shaft gear and the toothed chain mesh and move when the closing plate 6 moves up and down, reducing the load on the closing plate 6 from the upper end and transferring part of the weight of the closing plate 6 to the lower end. On both sides of the movable frame 7, the upper end of the central furnace body 1 is equipped with a conveying pipe 2, and the side of the conveying pipe 2 is equipped with a transmission pipeline. The transmission pipeline and the conveying pipe 2 are used to ensure the supply of heating raw materials. The bottom of the central furnace body 1 is equipped with a support end 11, and the lower surface of the support end 11 is equipped with a friction plate 12. The friction plate 12 is designed with a material with a large coefficient of friction. It is installed at the bottom to increase the surface force and prevent the central furnace body 1 from moving during use, thereby increasing the stability of the device itself. The rear end of the central furnace body 1 is equipped with a control system 16, and a display panel is installed on the surface of the control system 16.

[0023] refer to Figure 3The main body is a movable frame 7. A tensioning mechanism 5 is installed on the upper end of the movable frame 7, and the surface of the tensioning mechanism 5 is provided with a tensioning port. A tensioning chain 4 is installed at the tensioning port. In addition, a snap-fit ​​plate 3 is installed on the surface of the closing plate 6, and the snap-fit ​​plate 3 engages with the tensioning chain 4. The tensioning chain 4 is composed of multiple rings. The bottom ring is directly embedded in the middle of the snap-fit ​​plate to form a closure. The upper end is connected to the tensioning mechanism 5. The movement of the tensioning mechanism 5 drives the movement of the tensioning chain 4, providing a tensioning effect to the closing plate 6, so that it can be opened or closed at the front port of the central furnace body 1. Due to the design of the recessed groove, the position of the closing plate 6 is close to the opening of the device. When the closing plate 6 descends to the limit... When in position, the interior of the central furnace body 1 can be kept sealed. The interior of the central furnace body 1 is provided with a quenching layer, and the bottom surface of the quenching layer is provided with an engagement groove. A placement plate 8 is installed on the engagement groove, and the two sides of the placement plate 8 are provided with outward protrusions that match the design of the engagement groove. The placement plate 8 is placed along the interior. The bottom of the placement plate 8 is equipped with rollers 9, and the surface of the control system 16 is equipped with telescopic columns 10. The telescopic columns 10 are connected to the surface of the placement plate 8. The extension and retraction of the placement plate 8 are controlled by the control system 16. Since it is mounted on the engagement groove, the placement plate 8 is kept flush when moving in and out. The design of the rollers 9 reduces friction and makes the movement of the placement plate 8 more convenient and faster.

[0024] refer to Figure 4 The main body is a quenched layer. The inner surface of the quenched layer is provided with a side groove, and several heating elements 14 are installed inside the side groove. Partition blocks 15 are installed inside the quenched layer, and interlocking blocks 13 are installed on the surface of the plate 8. Both interlocking blocks 13 and partition blocks 15 are made of special alloy, which ensures both heat insulation and hardness. They are designed along the texture between them to avoid gaps as much as possible when they mesh with each other. In addition, the number of heating elements 14 inside different partitions is not uniform, so the internal temperature is not uniform. The temperature insulation effect of the interlocking blocks 13 can avoid the transfer of temperature as much as possible.

[0025] In actual use, the device is first installed, and then the tensioning mechanism 5 is started to operate by the operation of the control system 16. The tensioning chain 4 is contracted to move the closed plate 6 connected to the surface upward until the space left at the opening of the central furnace body 1 is large enough. Then, the control system 16 is operated to push the telescopic column 10 on the surface of the placement plate 8 to the outside, thereby pushing the placement plate 8 out of the furnace. The position between each partition can be clearly understood by the installation of the surface interlocking block 13. The metal or other materials that need to be heat treated are placed in the appropriate position as needed. Then, the control system 16 is driven to pull the placement plate 8 back, and the heating material is transported to the inside through the transmission pipeline at the upper end, and finally reaches the heating element 14. The heat treatment operation is completed by heating through the heating element 14.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
