Description

Technical Field

[0001] This utility model relates to the field of multi-bar hot shear furnace technology, specifically a temperature control and adjustment mechanism for a multi-bar hot shear furnace. Background Technology

[0002] The multi-bar hot shearing furnace is a specialized piece of equipment for metal processing. It is mainly used for efficient and precise shearing of metal bars. By heating the metal to a suitable temperature, the shearing process becomes smoother, reducing material deformation and shearing force, and improving shearing quality and efficiency. This equipment is widely used in the steel and non-ferrous metal processing industries. It plays an important role in optimizing production processes, improving product precision, and reducing production costs, and is one of the indispensable tools in modern metal processing.

[0003] However, according to the existing announcement number CN218673185U, a temperature difference adjustment mechanism in a multi-bar hot shear furnace relates to the field of hot shear furnace technology. This temperature difference adjustment mechanism in a multi-bar hot shear furnace includes a hot air flow channel, which includes an air inlet and two first branch channels connected to the air inlet. The other end of each first branch channel is connected to two second branch channels. Each first branch channel and second branch channel is provided with an adjustment device for changing the size of the hot air flow orifice. By changing the size of the hot air flow orifice through the adjustment device, the hot air volume is proportionally distributed to different positions in the furnace, thereby adjusting the temperature difference in various parts of the furnace. In the above-mentioned temperature difference adjustment mechanism in a multi-bar hot shear furnace, since the sliding plate is hidden inside the shell and the sliding plate is small, the shell will conduct heat to the sliding plate itself under the condition of hot air flow for a long time. Therefore, when the operator moves the sliding plate hidden inside the shell, there is a risk of burns to the operator. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a temperature control mechanism in a multi-bar hot shear furnace, which can independently and quickly adjust the hot airflow passing through the furnace, thereby controlling the temperature of different conveying pipes. In addition, the temperature is adjusted by a knob, thus effectively preventing operators from touching the hot furnace shell and causing safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature control and adjustment mechanism in a multi-bar hot shear furnace, comprising a hot air conveying box and a sliding plate. The bottom inner side of the hot air conveying box is provided with several sets of air inlet diversion channels, and each set of air inlet diversion channels is provided with a sliding groove in the middle. The inner side of the sliding groove is provided with four sets of limiting grooves, and a sliding plate is slidably arranged inside the sliding groove. Four sets of locking strips are fixed on the outer side of the sliding plate and engage with the four sets of limiting grooves respectively. An adjusting cylinder is fixed on the front surface of the sliding plate, and an adjusting rod is threadedly connected inside the adjusting cylinder. A knob is fixed on the front surface of the adjusting rod. A through hole is provided inside the sliding plate, and it is of the same size and correspondingly arranged with the air inlet diversion channels.

[0006] By adopting the above technical solution, several sets of air inlet diversion channels can achieve independent temperature control for each hot air duct. The sliding groove and limiting groove allow the sliding plate to slide stably through the locking strip, thereby controlling the hot air flow of the air inlet diversion channel. Rotating the adjusting rod allows it to move the sliding plate through the adjusting cylinder. The knob makes it convenient for the operator to rotate the adjusting rod. The through hole is used to cooperate with and control the size of the hot air flow in the air diversion channel.

[0007] Furthermore, external mounting plates are fixed on both sides of the hot air conveying box, and an air inlet main channel is opened on the top inner side of the hot air conveying box. A hot air conveying pipe is fixed on the top of the hot air conveying box and connected to the air inlet main channel.

[0008] By adopting the above technical solution, the external mounting plate enhances the ease of installation and stability of the hot air conveying box. The main air inlet channel opened on the top of the inner side of the hot air conveying box, and the connection between the hot air conveying pipe fixed on the top and the main air inlet channel, constitute a highly efficient hot air conveying system.

[0009] Furthermore, the hot air conveying box has an air inlet secondary channel in the middle of its inner side, which is connected to the main air inlet channel and several sets of air inlet diversion channels.

[0010] By adopting the above technical solution, the secondary air inlet channel can evenly deliver hot air into the interior of several sets of air inlet diversion channels.

[0011] Furthermore, the bottom of the hot air conveying box is fixed with several sets of hot air exhaust pipes, which are respectively connected to several sets of air inlet diversion channels.

[0012] By adopting the above technical solution, several sets of hot air exhaust pipes can accurately deliver the hot air inside the air inlet diversion channel to the specific location that needs to be heated.

[0013] Furthermore, several sets of support frames are fixed on the front surface of the hot air conveying box.

[0014] By adopting the above technical solution, the support frame is used to provide a limiting support function for one end of the adjusting rod.

[0015] Furthermore, a retaining ring is fixed to the outer side of the adjusting rod and rotates and engages with the support frame.

[0016] By adopting the above technical solution, operators can easily rotate the adjustment rod by turning the knob without the need for additional fixing or locking devices, which simplifies the operation process and improves operation efficiency.

[0017] In summary, the present invention has the following main advantages:

[0018] This invention, by setting up an adjusting cylinder, a support frame, an adjusting rod, and a knob, allows the operator to simply rotate the knob when it is necessary to adjust the flow of hot air inside the air inlet diversion channel. This rotation of the knob causes the adjusting rod to rotate, and the adjusting rod is connected to the adjusting cylinder by a thread, and the sliding plate is engaged with the sliding groove. This allows the adjusting cylinder to move and adjust the position of the sliding plate, thereby allowing the through holes inside the sliding plate to interlock and close with the air inlet diversion channel, thus controlling the flow of hot air inside the air inlet diversion channel.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment:

[0026] A temperature control mechanism for a multi-bar hot shear furnace, such as Figures 1-4 As shown, the device includes a hot air delivery box 1 and a sliding plate 10. The bottom inner side of the hot air delivery box 1 is provided with several sets of air inlet diversion channels 6, and each set of air inlet diversion channels 6 is provided with a sliding groove 8 in the middle. The inner side of the sliding groove 8 is provided with four sets of limiting grooves 9, and the sliding plate 10 is slidably arranged inside the sliding groove 8. Four sets of locking strips 11 are fixed on the outer side of the sliding plate 10 and are engaged and slid with the four sets of limiting grooves 9 respectively. An adjusting cylinder 12 is fixed on the front surface of the sliding plate 10, and an adjusting rod 15 is threadedly connected inside the adjusting cylinder 12. A knob 17 is fixed on the front surface of the adjusting rod 15. A through hole 13 is provided inside the sliding plate 10, and it is of the same size and correspondingly arranged with the air inlet diversion channels 6.

[0027] The sliding plate 10 slides within the air inlet channel 6 at the bottom of the hot air delivery box 1 via the sliding groove 8. The through holes 13 inside the sliding plate 10 are of the same size and corresponding to the air inlet channel 6. This allows for precise control of the hot air flow area by adjusting the position of the sliding plate 10, thereby achieving precise adjustment of the hot air flow rate. The four sets of limiting grooves 9 on the inner side of the sliding groove 8 engage and slide with the four sets of locking strips 11 fixed on the outer side of the sliding plate 10, providing a stable sliding track and limiting function for the sliding plate 10. This ensures the stability and accuracy of the sliding plate 10 during the sliding process. The threaded connection between the adjusting cylinder 12 and the adjusting rod 15, as well as the knob 17 fixed on the surface of the adjusting rod 15, allow the operator to easily move the sliding plate 10 by rotating the knob 17, further improving the operability and convenience of the equipment.

[0028] See Figure 1 , Figure 2 and Figure 3 The hot air delivery box 1 has external mounting plates 2 fixed on both sides, and the hot air delivery box 1 has an air inlet main channel 3 on the top of its inner side. The hot air delivery box 1 also has a hot air delivery pipe 4 fixed on its top and connected to the air inlet main channel 3.

[0029] The external mounting plates 2 fixed on both sides of the hot air conveying box 1 provide a convenient installation interface for the equipment, so that the hot air conveying box 1 can be stably fixed in a suitable position, ensuring the stability and safety of the equipment during operation. Hot air can enter the main air inlet channel 3 from the hot air conveying pipe 4, which improves the utilization efficiency and heating effect of hot air.

[0030] See Figure 2 The hot air delivery box 1 has an air inlet secondary channel 5 in the middle of its inner side, which is connected to the air inlet main channel 3 and several sets of air inlet diversion channels 6 respectively.

[0031] The secondary air inlet channel 5, located in the middle of the inner side of the hot air delivery box 1, serves as a connecting bridge between the main air inlet channel 3 and several sets of air inlet diversion channels 6, allowing hot air to flow more smoothly from the main air inlet channel 3 into each air inlet diversion channel 6.

[0032] See Figure 1 and Figure 2 Several sets of hot air discharge pipes 7 are fixed at the bottom of the hot air delivery box 1, and are respectively connected to several sets of air inlet diversion channels 6.

[0033] Among them, several sets of hot air exhaust pipes 7 fixed at the bottom of the hot air delivery box 1 are connected to several sets of air inlet diversion channels 6. This design allows the hot air to be accurately delivered to the specific location that needs to be heated after being precisely controlled by the air inlet diversion channels 6 and then through the hot air exhaust pipes 7.

[0034] See Figure 1 and Figure 3 Several sets of support frames 14 are fixed on the front surface of the hot air conveying box 1;

[0035] Among them, several sets of support frames 14 fixed on the front surface of the hot air conveying box 1 provide additional support points for the adjusting rod 15.

[0036] See Figure 3 and Figure 4 A retaining ring 16 is fixed to the outside of the adjusting rod 15 and rotates and engages with the support frame 14.

[0037] The retaining ring 16 fixed on the outer side of the adjusting rod 15 is rotatably engaged with the support frame 14. This design enables the adjusting rod 15 to maintain a stable axial position during rotation, effectively preventing axial movement and detachment of the adjusting rod 15, and ensuring the smoothness and reliability of the adjustment process.

[0038] The implementation principle of this embodiment is as follows: First, the hot air delivery box 1 is stably fixed in a suitable position by the external mounting plates 2 on both sides. Then, the hot air delivery pipe 4 and several sets of hot air discharge pipes 7 at the bottom of the hot air delivery box 1 are connected to the external air inlet pipe and air delivery pipe, respectively. When it is necessary to adjust the flow rate of hot air inside several sets of air inlet diversion channels 6, the knob 17 is turned to drive the adjusting rod 15 to rotate. While the adjusting rod 15 is rotating, it will engage with the support frame 14 through the retaining ring 16 to achieve a rotation limit function. Then, the adjusting rod 15 is connected to the adjusting cylinder 12 by threads to drive the sliding plate 10 inside the sliding groove 8. When sliding, the two sets of locking strips 11 at the upper and lower ends of the sliding plate 10 will engage with the four sets of limiting grooves 9 opened inside the sliding groove 8, thereby providing auxiliary stabilization for the sliding plate 10. After that, by adjusting the position of the sliding plate 10, the through hole 13 inside can be staggered and closed with the air inlet diversion channel 6. By changing the position of the sliding plate 10, the position of the through hole 13 and the through hole between the air inlet diversion channel 6 can be adjusted to reduce the hot air flow rate between the air inlet diversion channel 6. Finally, when the appropriate position is adjusted, the knob 17 can be released. According to the direction of the rotation of the knob 17, rotating it in the opposite direction will increase the hot air flow rate inside the air inlet diversion channel 6.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
