Description

Technical Field

[0001] The utility model relates to the field of resistance furnaces for bolt processing, and particularly relates to a mesh belt type resistance furnace for bolt processing. Background Technique

[0002] The mesh belt type resistance furnace, as an efficient heat treatment equipment, is widely used in the industrial field and has the ability to continuously and automatically heat, dry, sinter or heat-treat materials. Its core components include a furnace body, heating elements, a mesh belt transmission system, and a precise temperature control system.

[0003] However, in the actual operation of the equipment, bolts, as key elements for connection and fixation in the mesh belt transmission system, differences in their specifications may pose potential safety hazards. In particular, when the diameter of the bolt does not match the size of the mesh belt holes, for example, when the bolt diameter is smaller, resulting in too large a gap with the mesh belt holes, then during the operation of the equipment, the bolt may slip off the mesh belt due to vibration or external forces. This will not only interrupt the normal working process of the equipment, but may also lead to serious production safety accidents.

[0004] In addition, the working environment where the mesh belt type resistance furnace is located, such as high temperature, corrosive gases or liquids, etc., will also have an adverse impact on the stability of the bolts. The high temperature environment may cause thermal expansion and deformation of the bolt material, thereby reducing its connection tightness with the mesh belt; while the corrosive medium may erode the bolt surface, causing its friction coefficient and connection strength to decrease. Therefore, ensuring the correctness of the bolt specifications and their adaptability to the environment is crucial for the safe operation of the mesh belt type resistance furnace. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a mesh belt type resistance furnace for bolt processing, which can effectively solve the problems raised in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A mesh belt type resistance furnace for bolt processing includes a support frame, side frames, a resistance furnace body, a heating assembly, a heating pipeline, and a sealed maintenance door. The side frames are located on both upper sides of the support frame. The resistance furnace body is installed on the two side frames, and the heating assembly is installed in the resistance furnace body. The heating pipeline is installed at the upper end of the resistance furnace body. The sealed maintenance door is installed at the side end of the resistance furnace body through a hinge assembly;

[0008] Two symmetrical driving rollers are installed on the two side frames, and an isolation mesh belt is sleeved on the two driving rollers. The bolt workpieces are driven by the isolation mesh belt into the resistance furnace body;

[0009] Both ends of the isolation mesh belt are provided with connecting mesh strips, and raised mesh strips are arranged between the isolation mesh belt and the connecting mesh strips. Multiple insertion tubes are inserted into the side wall mesh holes of the raised mesh strips, and a limit nut is sleeved on the tube body of the insertion tube. The limiting height of the side wall of the isolation mesh belt is adjusted by the folding degree of the raised mesh strip, and the raised mesh strip prevents the bolt from slipping off the side wall of the isolation mesh belt.

[0010] In a further preferred solution, the connecting mesh strip, the isolation mesh belt and the raised mesh strip are integrally designed, and the mesh hole sizes of the connecting mesh strip, the isolation mesh belt and the raised mesh strip increase in sequence from the middle to both sides;

[0011] In a further preferred solution, the insertion tube is a threaded tube, multiple limit nuts are sleeved on the insertion tube, and multiple anti-slip gaskets are sleeved on the tube body of the insertion tube. The anti-slip gaskets are adhesively fixed on the limit nuts;

[0012] In a further preferred solution, the raised mesh strip adjusts the tension of the isolation mesh belt, and the connection part of the raised mesh strip is designed in an arc shape;

[0013] In a further preferred solution, a high-temperature isolation belt is arranged between the resistance furnace body and the isolation mesh belt to reduce the heat leakage amount from the connection part of the isolation mesh belt and the resistance furnace body in the resistance furnace body;

[0014] In a further preferred solution, a high-temperature isolation cloth is arranged on the inner walls of the isolation mesh belt, the connecting mesh strip and the raised mesh strip.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, the design of the raised mesh strip is ingenious. It allows us to precisely adapt according to the size and shape of the bolt by adjusting the folding degree of the mesh strip. When used in combination with the limit nut and the insertion tube, they jointly provide excellent support and stable limit for the bolt, so as to ensure that the bolt can be firmly held on the side wall of the mesh belt during transmission and avoid slipping.

[0017] More ingeniously, we sleeved an anti-slip gasket on the insertion tube. This design not only significantly enhances the friction with the bolt, but also greatly improves the anti-slip performance, further ensuring the stability of the bolt during transmission.

[0018] In addition, the connection part of the raised mesh strip is designed in an arc shape. This design not only makes the appearance of the mesh belt more beautiful, but also makes the tension of the mesh belt adjustable. The operator can easily adjust the connection part according to actual needs, so as to change the tension degree of the mesh belt to meet the transmission requirements of bolts of different specifications.

[0019] With the assistance of a mesh - belt resistance furnace, the bolt processing process becomes both efficient and safe. The restrictive effect of the raised mesh bars ensures that the bolts remain in a stable position throughout the processing, effectively avoiding processing interruptions or product damage caused by dropping.

[0025] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0026] As Figure 1 - Figure 4 shown, a mesh - belt resistance furnace designed specifically for bolt processing is introduced. This device consists of multiple core components, including a support frame 1, side frames 2, a resistance furnace body 3, a heating component 4, a heating pipeline 5, and a sealed maintenance door 6. Among them, the side frames 2 are stably installed at the upper ends on both sides of the support frame 1, and the resistance furnace body 3 is stably installed on these two side frames 2. The heating component 4 is cleverly placed inside the resistance furnace body 3, responsible for providing a stable heat source, while the heating pipeline 5 is installed at the upper end of the resistance furnace body 3 to ensure uniform heat distribution. In addition, the sealed maintenance door 6 is installed at the side end of the resistance furnace body 3 through a hinge assembly, facilitating daily maintenance and repair.

[0027] To efficiently transfer the bolt workpieces into the resistance furnace body 3, two symmetric driving rollers 7 are installed on the two side frames 2. On these two driving rollers 7, a set of isolation mesh belt 9 is specially designed, which can stably transfer the bolt workpieces into the resistance furnace body 3 for heat treatment.

[0028] The design of the isolation mesh belt 9 is ingenious. Connecting mesh strips 8 are provided at both ends to increase the overall stability and durability of the mesh belt. Between the isolation mesh belt 9 and the connecting mesh strips 8, raised mesh strips 10 are also cleverly designed. Multiple insertion tubes 11 are inserted into the side wall mesh holes of these raised mesh strips 10, and limit nuts 12 are sleeved on the tube bodies of these insertion tubes 11. By adjusting the degree of folding of the raised mesh strips 10, we can precisely adjust the limiting height of the side wall of the isolation mesh belt 9, thus effectively preventing the bolts from slipping off the side wall of the mesh belt during transmission.

[0029] The connecting mesh strips 8, the isolation mesh belt 9 and the raised mesh strips 10 adopt an integrated design, and the mesh hole size gradually increases from the middle to both sides. This design helps to increase the air permeability and durability of the mesh belt. The insertion tubes 11 are threaded tubes, and multiple limit nuts 12 can be easily sleeved on the tube bodies to achieve quick adjustment. At the same time, in order to increase the anti-slip performance, multiple anti-slip gaskets are also sleeved on the tube bodies of the insertion tubes 11, and these gaskets are fixed on the limit nuts 12 by bonding.

[0030] The raised mesh strips 10 not only have the function of preventing the bolts from slipping, but also can adjust the tension of the isolation mesh belt 9. The connection part is designed in an arc shape, which is both beautiful and practical. In order to further improve the heat insulation performance of the equipment, a high-temperature isolation belt is provided between the resistance furnace body 3 and the isolation mesh belt 9, effectively reducing the heat leakage amount from the connection part of the mesh belt and the furnace body. In addition, high-temperature isolation cloth is provided on the inner walls of the isolation mesh belt 9, the connecting mesh strips 8 and the raised mesh strips 10 to further enhance the heat insulation effect of the equipment.

[0031] Processing process: Place the bolts to be processed evenly on the isolation mesh belt 9. Ensure that the bolts are evenly distributed on the mesh belt so that the heating process is more balanced. Start the heating component 4 in the resistance furnace body 3, and evenly transfer heat to the furnace through the heating pipeline 5. At the same time, close the sealed maintenance door 6 to ensure the sealing of the heating environment in the furnace. Start the driving roller 7 to drive the isolation mesh belt 9 to move uniformly on the side frame 2, so as to transport the bolt workpiece into the resistance furnace body 3 for heating treatment. In the resistance furnace body 3, the bolts are heated for a certain period of time to reach the predetermined heating temperature and heating time, thus completing the heat treatment process of the bolts. After the bolts are processed, drive the isolation mesh belt 9 to the outside of the resistance furnace body 3 through the driving roller 7, and take out the processed bolts.

[0032] The raised mesh strip 10 restricts the bolts on the isolation mesh belt 9 to prevent the bolts from falling: According to the size and shape of the bolts, by adjusting the degree of folding of the raised mesh strip 10, the insertion tube 11 in the sidewall mesh holes thereof is made to match the bolts. A limit nut 12 is sleeved on the insertion tube 11, and an anti-slip gasket is fixed to ensure that the bolts will not slip off the sidewall of the mesh belt during transmission. When the driving roller 7 drives the isolation mesh belt 9 to move, the bolts are stably transmitted on the mesh belt. The design of the raised mesh strip 10 can ensure that the bolts always remain within the mesh belt during transmission and prevent them from falling.

[0033] During the transmission of the bolts, the operator should monitor the state of the bolts in real time to ensure that the adjustment effect of the raised mesh strip 10 is good and the bolts are stably transmitted on the mesh belt. If it is found that the bolts are unstable during transmission, the tension of the mesh belt can be changed by adjusting the connection of the raised mesh strip 10 to ensure the stable transmission of the bolts. Using a mesh belt type resistance furnace to realize bolt processing and using the raised mesh strip 10 to restrict the bolts on the isolation mesh belt 9 to prevent the bolts from falling can ensure the high efficiency, safety and stability of bolt processing.
