Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to an aging furnace. Background Technology

[0002] Aging furnaces are key pieces of equipment widely used in the heat treatment of metallic materials, especially in the production of aluminum alloy components in the aerospace and automotive industries. Their operation typically involves using a material trolley to transport the workpieces to be treated into the furnace for heating and heat preservation.

[0003] In routine production operations, material trolleys carrying heavy loads frequently travel between the loading area and the furnace on fixed tracks or the ground. During workpiece transfer, loading and unloading, and daily workshop activities, metal shavings, scale, small fallen parts, or other hard debris inevitably scatter along the trolley's path.

[0004] When the heavily loaded trolley moves, its wheels run over these debris, causing minor issues like bumpy operation and obstructed movement, affecting production rhythm; more serious issues can cause permanent damage to the wheel surface, such as dents and cracks, or even lead to serious safety accidents like wheel jamming or derailment, resulting in production interruptions and high maintenance costs. Currently, manual cleaning of the tracks is usually done periodically, which is not only inefficient and increases the labor intensity of workers, but also cannot guarantee that the path is clean before each trolley operation, and safety hazards still exist. Therefore, this utility model proposes an aging furnace to address the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an aging furnace, which aims to improve the problems of some existing aging furnaces where the material trolley is obstructed and its wheels are damaged due to debris scattered on the path of the material trolley, and there is a lack of automated cleaning methods.

[0006] This utility model provides an aging furnace, including a shell, an iron plate movably disposed for entering and exiting the shell, a wheel fixedly connected to the bottom of the iron plate, and a cleaning mechanism fixedly connected to the bottom of the iron plate.

[0007] The cleaning mechanism includes a concave cylinder, the outer circumferential surface of which abuts against the tread surface of the wheel to form a frictional transmission, and an inclined groove is formed on the inner wall of the concave cylinder.

[0008] Furthermore, the cleaning mechanism also includes a roller and a brush. The roller is slidably fitted in the inclined groove. The roller is fixedly connected to the brush through a connecting block. The rotation of the wheel drives the concave cylinder to rotate, and through the cooperation of the inclined groove and the roller, the brush is finally driven to reciprocate.

[0009] Preferably, to ensure the stability of the reciprocating motion of the brush, the cleaning mechanism further includes a connecting plate, a long plate, and an L-shaped block; the connecting plate is fixedly connected to the bottom of the iron plate, the long plate is fixedly connected to the connecting plate, the L-shaped block is fixedly connected between the roller and the connecting block, and the L-shaped block is slidably connected to the long plate.

[0010] Preferably, the aging furnace further includes a convergence mechanism disposed above the iron plate, the convergence mechanism including a motor and a support rod driven by the motor, for guiding the material placed on the iron plate toward the center position.

[0011] Preferably, the approaching mechanism further includes a connecting rod and an inclined block; the motor drives the support rod to move through the connecting rod, and the inclined block is fixedly connected to the top of the support rod, thereby squeezing and guiding the material through the inclined block.

[0012] Preferably, to ensure the accuracy of the movement of the support rod, a limiting component is connected to the bottom of the support rod to guide and limit its movement and prevent it from deflecting.

[0013] Preferably, the limiting component includes a sliding block fixed to the bottom of the support rod and a groove fixed to the iron plate or its extension structure; the sliding block is slidably engaged in the groove, forming a stable sliding guide relationship.

[0014] Preferably, the shell has an opening for the iron plate to enter and exit, and the opening is equipped with a liftable gate to close the furnace opening when not in the entry and exit state, so as to maintain the furnace temperature.

[0015] Preferably, the aging furnace further includes a tensioning frame connected to the gate, the tensioning frame being used to drive the gate to rise and fall, thereby realizing the automatic opening and closing of the furnace opening.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that debris on the material trolley's travel path in the aging furnace easily obstructs the trolley's movement or damages the wheels by setting a cleaning mechanism driven by wheels and linked to a brush for reciprocating motion at the bottom of the iron plate. It achieves the technical effect of automating and passively cleaning the trolley's travel path, thereby ensuring the smooth operation of the trolley and extending the service life of the wheels.

[0018] 2.

[0029] 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.

[0030] Example:

[0031] Reference Figures 1 to 4 This utility model provides an aging furnace, which aims to solve the problem in the prior art where the material trolley of the aging furnace is obstructed or its wheels are damaged due to the accumulation of debris on the track.

[0032] like Figure 1As shown, the aging furnace includes a shell 1 and an iron plate 2 movably disposed for entering and exiting the shell 1. The opening of the shell 1 is provided with a gate 3 that can be driven to rise and fall by a tensioning frame 4. A cleaning mechanism 5 is fixedly connected to the bottom of the iron plate 2, and a gathering mechanism 6 is provided above the iron plate 2. The material is placed on the iron plate 2, and the iron plate 2 moves on the ground or on a track by the wheels 51 at its bottom to complete the heat treatment operation of entering and exiting the shell 1.

[0033] Reference Figure 2 and Figure 3 The structure of the cleaning mechanism 5 is described in detail below. The cleaning mechanism 5 includes a concave cylinder 52, a roller 53, a connecting block 54, and a brush 58. The outer circumferential surface of the concave cylinder 52 abuts against the tread surface of the wheel 51 at the bottom of the iron plate 2 to form a friction transmission. When the wheel 51 rolls due to the movement of the iron plate 2, the concave cylinder 52 will rotate synchronously. An annular inclined groove 59 is provided on the inner wall of the concave cylinder 52. The roller 53 is housed in the concave cylinder 52 and slides in the inclined groove 59. When the concave cylinder 52 rotates, the roller 53 will reciprocate linearly along the axial direction of the concave cylinder 52 under the constraint of the inclined groove 59. The roller 53 is fixedly connected to the brush 58 through the connecting block 54, thereby transmitting the reciprocating motion of the roller 53 to the brush 58, so that it can clean the ground in front of the path of the iron plate 2.

[0034] To ensure that the cleaning mechanism 5 operates smoothly during operation and to prevent the brush 58 from shaking or deflecting, the cleaning mechanism 5 also includes a set of support and guide structures.

[0035] Reference Figure 2 and Figure 3 The supporting guide structure includes a connecting plate 57, a long plate 56, and an L-shaped block 55. The connecting plate 57 is fixedly connected to the bottom of the iron plate 2 by welding or bolts, and the long plate 56 is fixedly connected to the connecting plate 57, providing a sliding track for the L-shaped block 55. The L-shaped block 55 is fixedly connected between the roller 53 and the connecting block 54. The L-shaped block 55 is slidably connected to the long plate 56 with its horizontal part. This structure provides stable linear guidance for the reciprocating brush 58, ensuring the accuracy and effectiveness of the cleaning action.

[0036] Reference Figure 1 and Figure 4 The approaching mechanism 6 includes a motor 61, a connecting rod 62, and a support rod 63. The motor 61 serves as a power source, driving the support rod 63 to perform reciprocating linear motion through the connecting rod 62. An inclined block 64 is fixedly connected to the top of the support rod 63. When the two support rods 63 move towards each other, the two inclined blocks 64 together form a V-shaped guide opening, thereby squeezing and guiding the material placed on the iron plate 2 towards the center position.

[0037] To ensure the stability and accuracy of the movement of the support rod 63, a limiting component 65 is also connected to its bottom. The limiting component 65 includes a sliding block 651 fixed to the bottom of the support rod 63 and a groove 652 fixed to the iron plate 2 or its extension structure. The sliding block 651 is slidably engaged in the groove 652. Through this cooperation between the track and the slider, the support rod 63 is effectively prevented from tilting or swinging when it is subjected to force.

[0038] As a preferred embodiment, in order to effectively seal the furnace opening during the interval between the iron plate 2 entering and exiting the shell 1, so as to maintain the temperature inside the shell 1 and improve operational safety;

[0039] Reference Figure 1 A gate 3 that can move up and down is provided at the opening on the housing 1 for the iron plate 2 to enter and exit. A tension frame 4 is connected to the upper part of the gate 3. The tension frame 4 drives the gate 3 to move up and down by a drive source such as a hydraulic cylinder or a screw, thereby realizing the opening and closing of the opening of the housing 1.

[0040] The implementation principle of this application embodiment is as follows: When the iron plate 2 needs to be removed from the housing 1, the tensioning frame 4 first drives the gate 3 to rise to open the furnace opening. Then the iron plate 2 begins to move outward. During the movement, the wheel 51 at its bottom rolls. Since the outer circumferential surface of the concave cylinder 52 abuts against the tread surface of the wheel 51, the rolling of the wheel 51 will drive the concave cylinder 52 to rotate synchronously through friction. As the concave cylinder 52 rotates, the roller 53 inside it, under the guidance and constraint of the inclined groove 59, converts the rotational motion into reciprocating linear motion along the axial direction of the concave cylinder 52. The motion is transmitted to the brush 58 through the connecting block 54, driving the brush 58 to reciprocate and clean the ground, thereby effectively cleaning the debris on the path of the iron plate 2 and solving the problem of the trolley being obstructed or the wheels being damaged due to debris.

[0041] When it is necessary to feed material into the aging furnace, the material is placed on the iron plate 2 outside the furnace. At this time, the motor 61 of the approaching mechanism 6 is activated. The motor 61 drives the support rod 63 to move towards each other through the connecting rod 62. The inclined block 64 fixed on the top of the support rod 63 moves towards the center, forming a V-shaped guide to squeeze and guide the material, so that it automatically gathers to the center position of the iron plate 2. During the movement of the support rod 63, the sliding block 651 at its bottom slides in the groove 652, ensuring the smoothness and accuracy of the whole process. This solves the problem of inaccurate positioning when manually feeding material and ensures that the material can enter the optimal heat treatment area inside the furnace.
