Description

Technical Field

[0001] This utility model relates to the field of curing oven technology, specifically a curing oven for the production of zinc-steel guardrails. Background Technology

[0002] To improve the structural strength, weather resistance, corrosion resistance, and durability of zinc-steel guardrails, metal curing ovens are commonly used to cure the pipes and rods of the guardrails. A metal curing oven is a device used to enhance the bonding stress of materials through heating. It alters the internal structure of materials through high-temperature treatment. For example, metal workpieces may have low hardness after quenching, but their hardness will significantly increase after aging treatment in a curing oven. Therefore, it is widely used in various industries for curing anti-oxidation coatings on parts, improving weather resistance and durability, ensuring stability and reliability, and enhancing corrosion resistance and strength.

[0003] The existing curing oven has a longitudinal slide rail on top. The zinc-coated steel pipes and rods to be cured are loaded into a special basket and suspended on the longitudinal slide rail. The basket is then manually pulled into the oven through the front door. After curing, the basket is manually pulled out of the oven along the longitudinal slide rail. During operation, frequent manual entry and exit from the curing oven to move the basket is required. The basket, carrying zinc-coated steel pipes and rods, is quite heavy and subject to inertia, making manual operation laborious, inefficient, and unsuitable for high-efficiency production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a curing oven for the production of zinc-steel guardrails, which solves the problems of cumbersome loading and unloading, labor-intensive operation, and low efficiency when using existing curing ovens to process the pipes and rods of zinc-steel guardrails.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A curing oven for producing zinc-steel guardrails includes an oven body with an open front and back and an oven door on each side. At least one set of annular tracks is fixed inside the upper part of the oven body. Multiple sets of rollers are rotatably connected inside the annular tracks. A connecting seat is rotatably connected to the axle of each roller. A lifting ring for suspending a loading basket is fixedly connected to the bottom of the connecting seat.

[0007] A fixing block is fixedly connected to the top of the connecting seat. The fixing block is fixed at equal intervals on a steel cable, and a fixing plate is also fixed at equal intervals on the steel cable. A dial is rotatably connected to the top of the inner wall of the furnace body through the fixing seat and is rotatably clamped on the steel cable and the fixing plate. The dial is connected to the reducer through a rotating shaft. A drive motor connected to the reducer is fixedly installed on the top of the furnace body.

[0008] Preferably, the furnace door is a double door of the same width.

[0009] Preferably, the annular track is arranged along the length of the furnace body, and the annular track is fixedly installed inside the furnace body above by a fixing frame.

[0010] Preferably, the fixing disk is a disc with a smooth curved edge, the upper half of the fixing block has the same shape and size as the upper half of the fixing disk, and the distance between the fixing block and the adjacent fixing disk is equal to the distance between two adjacent fixing disks.

[0011] Preferably, the dial includes slots for engaging and fixing discs arranged at equal intervals on the circumference, and a groove for engaging steel cables arranged on the circumference.

[0012] Preferably, the drive motor is a servo motor.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a circular track and a drive motor to power a dial. A steel cable then moves a basket containing zinc-coated steel guardrail pipes and rods, suspended by a lower ring, along the circular track. This allows the basket to be easily moved from the furnace door to the furnace interior without manual intervention, simplifying operation. After one batch of zinc-coated steel guardrail pipes and rods has cured, the material is unloaded at the rear furnace door and loaded at the front furnace door. The high overlap between loading and unloading times saves time and improves efficiency. This invention solves the problems of cumbersome loading and unloading, labor-intensive operation, and low efficiency associated with existing curing furnaces for processing zinc-coated steel guardrail pipes and rods.

[0022] 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.

[0023] like Figure 1-6 As shown, this utility model provides a technical solution: a curing furnace for the production of zinc steel guardrails, including a furnace body 1. The front and back of the furnace body 1 are open and each is provided with a furnace door 2. The furnace door 2 is a double door with the same width. After opening, the furnace body 1 has a large opening width, which facilitates the loading and unloading of guardrail steel pipes. At least one set of annular tracks 3 is fixed inside the upper part of the furnace body 1. The annular tracks 3 are arranged along the length of the furnace body 1. The annular tracks 3 are fixedly installed inside the upper part of the furnace body 1 by a fixing frame 14. Multiple annular tracks 3 can also be arranged in parallel according to the width of the furnace body 1. Only components such as rollers 4, steel cables 8 and drive motors 13 need to be set accordingly.

[0024] Multiple sets of rollers 4 are rolled inside the circular track 3. A connecting seat 5 is rotatably connected to the axle of the roller 4. A lifting ring 6 for suspending the loading basket is fixedly connected to the bottom of the connecting seat 5. The zinc steel pipe fitting to be cured is placed in a special basket and suspended on the lifting ring 6 by a hook.

[0025] A fixing block 7 is fixedly connected to the top of the connecting seat 5. The fixing block 7 is fixed at equal intervals on a steel cable 8. The steel cable 8 is also fixed at equal intervals with fixing discs 9. The fixing discs 9 are discs with smooth curved edges. The upper half of the fixing block 7 and the upper half of the fixing disc 9 have the same shape and size. The distance between the fixing block 7 and the adjacent fixing disc 9 is equal to the distance between two adjacent fixing discs 9.

[0026] A dial 11 is rotatably connected to the top of the inner wall of the furnace body 1 via a fixed base 10, and is rotatably engaged with the steel cable 8 and the fixed plate 9. The dial 11 includes slots for engaging the fixed plate 9 at equal intervals on the circumference and a groove for engaging the steel cable 8 on the circumference. The dial 11 is connected to the reducer 12 via a rotating shaft. A drive motor 13, which is connected to the reducer 12, is fixedly installed on the top of the furnace body 1. The drive motor 13 is a servo motor.

[0027] Working principle:

[0028] The drive motor 13 drives the dial 11 through the reducer 12. The rotation of the dial 11 drives the connecting seat 5 and roller 4 to move along the circular track 3 via the fixed plate 9 and steel cable 8. The front furnace door 2 is opened, and multiple baskets containing zinc steel guardrail pipes and rods are suspended sequentially onto multiple lifting rings 6. The baskets containing zinc steel guardrail pipes and rods to be cured can be easily moved from the furnace door 2 to the inside of the furnace body 1. After the furnace door 2 is closed, the curing process is carried out. After the curing of one batch of zinc steel guardrail pipes and rods is completed, the front and back furnace doors 2 are opened. Multiple baskets containing cured zinc steel guardrail pipes and rods suspended on multiple lifting rings 6 are removed sequentially at the back furnace door 2 for unloading. Then, multiple baskets containing zinc steel guardrail pipes and rods to be cured are suspended on the empty lifting rings 6 at the front furnace door 2 for loading. Loading and unloading are carried out simultaneously, which is efficient and convenient.
