Description

Technical Field

[0001] This invention relates to the field of multi-purpose furnace technology, and more particularly to a multi-purpose furnace with a material cooling zone. Background Technology

[0002] In modern industrial production, especially after heat treatments such as quenching and normalizing, metal workpieces typically require immediate and controlled cooling to fix their microstructure and properties. Traditional multi-purpose furnace systems often have separate and fixed functional units for heating and cooling. After heating in the furnace, the workpiece is transferred to a separate cooling chamber or tank for further processing.

[0003] In this type of production line, after the workpiece has been heated in the furnace, it is continuously conveyed out via the conveyor rollers of the discharge mechanism. A key technical requirement is to immediately and uniformly pre-cool or pre-cool the high-temperature workpiece during this conveying process to precisely control its cooling trajectory and lay the foundation for subsequent processes.

[0004] Existing processes involve installing fixed air boxes or air outlet arrays above or below the conveyor rollers to cool the passing workpieces. The main drawback of this method is that the cooling air always acts on a fixed area. When the workpieces are short or spaced far apart, a large amount of cold air blows directly onto the unloaded rollers, resulting in energy waste. Therefore, there is an urgent need for a multi-purpose furnace with a material cooling zone that allows for dynamic adjustment of the air outlet position. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose furnace with a material cooling zone.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose furnace with a material cooling zone includes a multi-purpose furnace, with a feeding channel and a discharging channel at both ends of the multi-purpose furnace. Cooling air boxes are installed on both sides of the discharging channel, and the cooling air boxes are provided with multiple openable and closable air jets. Multiple baffles for opening and closing the air jets are vertically movable inside the cooling air boxes. The baffles are vertically movable by a column. A slide is movably installed on the discharging channel by a workpiece, and the slide pushes the column vertically by an inclined plane.

[0007] In addition, a preferred structure is that multiple discharge rollers are rotatably arranged on the discharge channel, and the workpieces are all conveyed and moved out through the discharge rollers.

[0008] In addition, a preferred structure is that slide rails are provided on both sides of the discharge roller on the discharge channel, and sliders adapted to the slide rails are fixedly provided at the bottom of the slide frame.

[0009] In addition, a preferred structure is that multiple push blocks are fixedly installed on the carriage, each push block has a top inclined surface, and the height of the push block is greater than the height of the workpiece.

[0010] Furthermore, in a preferred configuration, each side of the cooling air box is connected to an air inlet pipe for supplying cold air, and the inner cavity of the cooling air box is adapted to and connected to a jet nozzle.

[0011] In addition, in a preferred configuration, the inner cavity of the cooling air box is vertically movable with baffles located behind the jet nozzle, and the corresponding baffles on the cooling air box are adapted to have top cavities, and the baffles are adapted to extend out from the top cavities.

[0012] In addition, a preferred structure is that each of the baffles is fixedly provided with an anti-fall-off component at its bottom, and the diameter of the anti-fall-off component is larger than that of the top cavity.

[0013] In addition, in a preferred configuration, the baffles on both sides of the cooling air box are fixedly connected by a connecting crossbar, and the bottom of the connecting crossbar is fixedly provided with multiple columns adapted to the push block.

[0014] In addition, a preferred structure is that the bottom of each column is provided with a bottom slope and a bottom plane, and the slope between the bottom slope and the top slope is matched.

[0015] The beneficial effects of this invention are as follows: the multi-purpose furnace can heat the workpiece; the adaptive arrangement between the cooling air box, baffle and slide allows the air jet to open and close dynamically as the workpiece moves. This ensures that when the workpiece moves, the cooling air box only blows air in its corresponding area and automatically closes after the workpiece leaves, thus avoiding energy waste.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Reference Figure 1-8 A multi-purpose furnace with a material cooling zone includes a multi-purpose furnace 1. A feeding channel 11 and a discharging channel 2 are respectively provided at both ends of the multi-purpose furnace 1. Cooling air boxes 3 are installed on both sides of the discharging channel 2, and the cooling air boxes 3 have multiple openable and closable air jets 32. Multiple baffles 4 for opening and closing the air jets 32 are vertically movable inside the cooling air boxes 3. The baffles 4 are vertically movable via columns 42. A slide 5, pushed by a workpiece, is movably installed on the discharging channel 2, and the slide 5 pushes the columns 42 vertically via an inclined plane.

[0020] Multiple discharge rollers 21 are rotatably mounted on the discharge channel 2, and workpieces are conveyed and moved out through the discharge rollers 21. The discharge rollers 21 are used to transfer workpieces out of the discharge channel 2.

[0021] In this design, slide rails 22 are provided on both sides of the discharge roller 21 on the discharge channel 2, and sliders 52 adapted to the slide rails 22 are fixedly provided at the bottom of each slide frame 5. The slide rails 22 allow the sliders 52 to move along them, thus ensuring the stability of the slide frame 5.

[0022] The slide 5 is fixedly provided with multiple push blocks 51, each push block 51 having a top inclined surface 511, and the height of the push block 51 is greater than the height of the workpiece.

[0023] Each side of the cooling air box 3 is connected to an air inlet pipe 31 for supplying cold air, and the inner cavity of the cooling air box 3 is adapted to and connected to the jet nozzle 32.

[0024] In this design, the inner cavity of the cooling air box 3 is vertically fitted with baffles 4 located behind the jet nozzle 32. A top cavity 33 is adapted to be formed on each baffle 4 on the cooling air box 3, and each baffle 4 extends out from the top cavity 33. The baffles 4 effectively block the jet nozzle 32. It is worth noting that the baffles 4 are equipped with existing sealing elements to ensure the airtightness between the jet nozzle 32 and the top cavity 33. This is prior art and will not be elaborated upon further.

[0025] Each baffle 4 has an anti-detachment component 43 fixedly installed at its bottom, and the diameter of the anti-detachment component 43 is larger than that of the top cavity 33. The anti-detachment component 43 is used to prevent the baffle 4 from falling out of the top cavity 33.

[0026] The baffles 4 on both sides of the cooling air box 3 are fixedly connected by a connecting crossbar 41, and multiple columns 42 adapted to the push block 51 are fixedly installed at the bottom of the connecting crossbar 41.

[0027] The bottom of each column 42 is provided with a bottom slope 421 and a bottom plane 422, and the slope between the bottom slope 421 and the top slope 511 is matched.

[0028] In this embodiment, the multi-purpose furnace 1 consists of a heating chamber, a conveying system, and a control system. The workpiece is first heated in the sealed heating chamber by an electric heating element or a burner, and then held at that temperature in a controlled atmosphere (carburizing gas, protective gas) to complete the predetermined heat treatment process. It is worth noting that the multi-purpose furnace 1 is prior art and is not part of the main technical problem to be solved in this technical solution, therefore it will not be described in detail in this invention.

[0029] Furthermore, during the workpiece processing, the workpiece is simply placed on the feed channel 11, and then enters the multi-purpose furnace 1 through the feed channel 11 for heating, thus realizing the workpiece heating process. Subsequently, the workpiece is conveyed out from the discharge channel 2.

[0030] The workpiece in the discharge channel 2 moves by the discharge roller 21. During the movement of the workpiece, it can push the slide 5, so that the slide 5 and the push block 51 move synchronously with the workpiece.

[0031] During the movement of the carriage 5, the top inclined surface 511 on the push block 51 can push the bottom inclined surface 421 on the column 42 to push the column 42 upward. At the same time, the connecting crossbar 41 and the baffles 4 on both sides move upward synchronously. At this time, the air jets 32 on both sides are opened, and the cold air in the cooling air box 3 can be blown out from the air jets 32, thereby achieving the cooling of the workpiece.

[0032] After the carriage 5 passes the baffle 4 on that side, the bottom plane 422 on the uprights 42 on both sides will automatically fall onto the workpiece, thus preventing the baffles 4 on both sides from closing. At this time, air can continue to blow into the air jets 32 for cooling. Only after the workpiece passes through the connecting crossbar 41 will the baffles 4 on both sides automatically fall under their own weight, thus closing the air jets 32 on both sides. In this way, as the workpiece continues to move, only the air jets 32 on both sides of the workpiece can automatically open, and they can automatically close after the workpiece has passed through them.

[0033] Once the carriage 5 has moved to its end, the user only needs to return the carriage 5 to its original position to reset it, so that the cooling operation of the next workpiece can be carried out.

[0034] In this invention, the multi-purpose furnace 1 can be used to heat the workpiece. Through the adaptive arrangement between the cooling air box 3, the baffle 4 and the slide 5, the air jet 32 ​​can be dynamically opened and closed as the workpiece moves. This ensures that when the workpiece moves, the cooling air box 3 only blows air in its corresponding area and automatically closes after the workpiece leaves, thus avoiding energy waste.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
