Description

Technical Field

[0001] This invention relates to the field of forging cooling equipment, and in particular, to a forging cooling box. Background Technology

[0002] "Hot forging" is a relatively new term, and its origin is difficult to find in dictionaries. This is because hot forging is an advanced specialized process that has only recently developed from modern precision forging and hot extrusion. With societal progress and technological advancements, the machinery industry has placed new demands on the mechanical strength of mechanical parts. Improving mechanical strength generally involves two methods: changing the material of the parts or changing the processing method. Hot forging is one of the effective methods for improving the mechanical properties of parts by changing the processing method, thus, like forging, it possesses strong vitality and a promising future. Like precision forging, hot forging involves heating the metal billet and then shaping it in a die. However, except for large hot forged parts, hot forging is generally a one-time process, while precision forging typically involves several pressure forming steps.

[0003] After forgings are formed by hot stamping, some forgings will have burrs (rough edges) on the edges. In addition, the forgings are also at high temperatures at this time, and need to be cooled down. Due to process requirements, the cooling process needs to be air-cooled or natural-cooled. Therefore, waiting for the forgings to cool down naturally takes a long time, which greatly affects the processing efficiency.

[0004] The workpiece is positioned relatively low after being processed by the forging press, and subsequent processing stations need to adapt the workpiece transfer according to the site conditions. Therefore, it is evident that the forging also needs to be transferred and its position adjusted. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art and at least partially solve the technical problems in the related art by providing a forging cooling box that can improve the cooling rate of forging billets and adjust the conveying position to facilitate the docking of equipment at different workstations.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a forging cooling box, comprising a support frame, a cooling conveyor, and a fan, characterized in that: the cooling conveyor is used for lifting and cooling the hot-forging billet and multiple such conveyors are provided, each having an inlet, an outlet, and an air outlet; the inlet of each individual cooling conveyor is installed at a lower position, and the outlet is installed at a higher position; the multiple cooling conveyors are fixed on the support frame, wherein the outlet of the preceding cooling conveyor is connected to the inlet of the following cooling conveyor, and the hot-forging billet enters the following inlet from the preceding outlet by gravity sliding; the fan is connected to the air inlet of each cooling conveyor through a pipeline, and the air outlet faces the hot-forging billet on the cooling conveyor.

[0007] Preferably, a wind box is provided between the front and rear of the support frame, and the wind box is provided with the air outlet on the side of each cooling conveyor, and a guide plate is provided at the air outlet.

[0008] Preferably, the fan is installed inside the air box and connected to the outside to provide an air source.

[0009] Preferably, the plurality of cooling conveyors are arranged in an ascending, rotating, and staggered pattern.

[0010] Preferably, the cooling conveyor includes a frame, a transmission mechanism mounted on the frame, and an air chamber assembly fixed to the side of the frame to supply air to the transmission mechanism. The air outlets are arranged in a row inside the air chamber assembly. The transmission mechanism includes a steel track, transmission rollers, and a sprocket drive assembly. The steel track is sleeved on two transmission rollers and driven by the sprocket drive assembly.

[0011] Preferably, a feed hopper is provided on the feed inlet, and the feed hopper is provided with a guide ramp, which is used to adjust the position of the hot-forging billet.

[0012] Preferably, the support frame is provided with casters at the bottom and handles on both sides.

[0013] Preferably, multiple cooling conveyors can be docked to each other, and the outlet on the support frame is connected to the inlet of another support frame via a slide rail.

[0014] Compared with the prior art, the technical effects of the present invention are mainly reflected in the following aspects:

[0015] 1. The overall structure is compact, which can lift the hot forging billet to a high height, extend its transportation distance, and allow the hot forging billet to be air-cooled during transportation, thereby improving the cooling efficiency of the billet;

[0028] The following is in conjunction with the appendix Figure 1 To the attached Figure 6 The specific embodiments of the present invention will be further described in detail to make the technical solution of the present invention easier to understand and master. Example

[0029] A forging cooling box, reference Figure 1 As shown, it includes a support frame 1, a cooling conveyor, and a fan 3. The cooling conveyor is used for lifting and cooling the hot-forged billet and is provided in multiple ways, having a feed inlet 211 and a discharge outlet 214, an air inlet 231 and an air outlet 232.

[0030] The feed inlet 211 of each individual cooling conveyor is installed at a low position, and the discharge outlet 214 is installed at a high position; the cooling conveyor can lift the material at a height and transport it over long distances, and air-cool the billet.

[0031] Multiple cooling conveyors are fixed on support frame 1. The discharge port 214 of the preceding cooling conveyor is connected to the inlet 211 of the following cooling conveyor. The hot-burning billet enters the following inlet 211 from the discharge port 214 by falling. The fan 3 is connected to the air inlet 231 of each cooling conveyor through pipelines, and the air outlet 232 faces the hot-burning billet on the cooling conveyor.

[0032] The preferred implementation structure of this solution is, for example: Figure 1 As shown, multiple cooling conveyors are arranged in an ascending, rotating, and staggered pattern. Specifically, in Figure 3 and Figure 4 As can be understood, the billet's transport path is as follows: it enters from inlet 11 of frame 21, is lifted by cooling conveyor ①, then falls at outlet 214 to inlet 211 of cooling conveyor ②, is lifted again, and is subsequently transported on cooling conveyors ③, ④, and ⑤, finally exiting at outlet 12 of support frame 1. In this embodiment, this back-and-forth transport not only extends the billet's transport distance but also increases the height of the billet output. Fan 3 provides airflow, which cools the billet through outlet 232.

[0033] Specifically, in combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As can be seen, the cooling conveyor includes a frame 21, a transmission mechanism 22 mounted on the frame 21, and an air chamber assembly 23 fixed to the side of the frame 21 to supply air to the transmission mechanism 22. Air outlets 232 are arranged in a row inside the air chamber assembly 23. The transmission mechanism 22 includes a steel track 221, transmission rollers 222, and a sprocket drive assembly 223. The steel track 221 is fitted onto two transmission rollers 222 and driven by the sprocket drive assembly 223. The sprocket drive assembly 223 is driven by a motor-driven chain, which drives the sprocket, and then the transmission rollers 222, thus enabling all cooling conveyors to transmit the blanks synchronously and at the same speed.

[0034] To ensure smooth connection between the billet at the inlet 211 and outlet 214, a feed hopper 212 is installed at the inlet 211. The feed hopper 212 is equipped with a guide ramp 213, which is used to adjust the position of the hot-forging billet. By adjusting the drop position of the billet through the guide ramp 213, the billet transfer process can be automatically completed by gravity, thus achieving automatic connection between the various cooling conveyors.

[0035] To facilitate movement of the entire mechanism, casters 4 are installed at the bottom of the support frame 1, and handles 5 are installed on both sides of the support frame 1. This allows multiple cooling conveyors to dock with each other, and the outlet 12 on the support frame 1 is connected to the inlet of another support frame 1 via a slide rail.

[0036] In summary, this design prioritizes a compact overall structure, enabling the high-lifting of hot-forging billets, extending their transport distance, and facilitating air cooling during transport to improve cooling efficiency. The billet transport utilizes an upward-rotating method, combined with a long, narrow cooling conveyor for efficient space utilization, resulting in a compact overall structure with high space efficiency, facilitating handling and use. It also allows for easy overall movement and assembly, making it more adaptable to different working conditions and processing volumes, and allowing for convenient adjustment of the travel distance. Example

[0037] A forging cooling box, reference Figure 7 , 8 The system comprises a support frame 1, a cooling conveyor 2, and a fan 3. Multiple cooling conveyors 2 are used for lifting and cooling the hot-forging billets. Each conveyor has an inlet 211, an outlet 214, and an air outlet 232. The inlet 211 of each individual cooling conveyor 2 is installed at a lower position, and the outlet 214 is installed at a higher position. Multiple cooling conveyors 2 are fixed to the support frame 1. The outlet 214 of one cooling conveyor 2 connects to the inlet 211 of the next cooling conveyor 2. The hot-forging billets slide down by gravity from the outlet 214 to the inlet 211. The fan 3 is connected to the air outlet 232 of each cooling conveyor 2 via a fan box 6. The air outlet 232 faces the hot-forging billets on the cooling conveyor 2. A fan box is installed between the front and rear of the support frame 1. Each cooling conveyor 2 has an air outlet 232 on its side, and a guide plate 233 is installed at each air outlet 232. Fan 3 is installed inside the air box and connected to the outside to provide air source.

[0038] Embodiment 2 can be considered a more preferred example. The main design feature is that the bellows 6 is positioned in the middle, thus replacing the air chamber assembly 23 in Embodiment 1, integrating multiple air chamber assemblies 23 into a single unit. Figure 8 As can be seen, there is a fan 3 inside the bellows 6, which creates positive pressure inside the bellows 6, generating airflow at the (strip-shaped) air outlet 232, through which... Figure 9 As can be seen, efficient cooling is achieved by guiding the air through the guide plate 233. To adjust the material outlet position, a drop slide 7 directly connecting the higher to the lower level is installed inside the air box 6 at the material's endpoint (see...). Figure 8 This design allows materials to fall back, making it suitable for equipment located at low positions. As can be seen from this design, the fall-back slide 7 is concealed internally, without occupying external space.

[0039] In the above embodiments, the cooling conveyor 2 can be synchronously driven by a chain, and the chain can be installed and fastened by tension adjustment, which facilitates assembly and use.

[0040] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
