Description

Technical Field

[0001] The utility model relates to a mesh belt type tempering furnace suitable for small parts and components, belonging to the technical field of heat treatment equipment. Background Art

[0002] The mesh belt tempering furnace is a kind of equipment used for metal heat treatment, mainly used for tempering metal materials such as steel and iron. In the process of metal processing, metal workpieces after quenching or annealing usually become very hard and brittle. In order to increase their toughness and strength, tempering treatment is required. The mesh belt tempering furnace controls the temperature in the furnace and the speed of the transport mesh belt to achieve uniform heating and heat preservation of the metal workpiece, so as to soften and improve the mechanical properties of the metal material.

[0003] In the prior art, a loading mechanism is usually provided at the feeding end of the mesh belt tempering furnace to realize automatic loading, thereby reducing manual intervention and improving production efficiency. However, most of the existing loading mechanisms convey parts through conveyor belts. Therefore, when conveying small parts, small parts are easy to fall from the gaps of the conveyor belt to the bottom of the conveyor belt or get stuck on the conveyor belt. Therefore, the conveyor belt needs to be cleaned every time the parts to be processed are replaced to avoid quality accidents caused by mixing of different parts, which increases manual processes and reduces production efficiency. Utility Model Content

[0004] The utility model aims to provide a mesh belt tempering furnace suitable for small parts, which can prevent small parts from falling on the bottom of a feeding mechanism or getting stuck on the feeding mechanism, thereby avoiding quality accidents caused by mixing of parts.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a mesh belt tempering furnace suitable for small parts, the mesh belt tempering furnace comprising:

[0006] A quenching furnace, comprising a furnace and a conveying line running through both ends of the furnace;

[0007] A feeding assembly is arranged at the feeding end of the furnace and docked with the conveyor line to convey small parts into the quenching furnace, and the feeding assembly includes a seamless feeding trough, a turnaround line arranged at the bottom of the seamless feeding trough, and a plurality of magnetic parts arranged on the turnaround line at intervals;

[0008] A discharge trough is obliquely arranged at the end of the seamless loading trough, and the angle between the seamless loading trough and the discharge trough is an acute angle. Under the action of the magnetic part, the small parts move from the seamless loading trough to the discharge trough, and separate from the magnetic part to slide along the discharge trough to the conveyor line.

[0009] Furthermore, the seamless feeding trough includes a horizontal section and an inclined section connected to the end of the horizontal section. The inclined section is disposed close to the conveyor line and partially located above the conveyor line.

[0010] Furthermore, the seamless feeding trough is in a U-shaped structure with an upward opening.

[0011] Furthermore, the rotary line includes an upper roller and a lower roller respectively disposed at two ends of the inclined section, a rotary belt connected between the upper roller and the lower roller, and a power member for driving the upper roller and / or the lower roller to rotate.

[0012] Furthermore, the magnetic members are arranged to extend along the width direction of the rotary belt.

[0013] Furthermore, the discharge trough and the seamless feeding trough are integrally formed or separately provided.

[0014] Furthermore, a pusher is provided at the connection between the horizontal section and the inclined section. The feeding member is used to push the small parts located in the horizontal section into the inclined section.

[0015] Furthermore, the pusher includes a paddle disposed in the seamless feeding trough and a driving member installed outside the seamless feeding trough to drive the paddle to rotate.

[0016] The beneficial effects of the present utility model are as follows: By providing a feeding assembly at the feeding end of the quenching furnace in this application, an automatic feeding process is realized. The rotary line arranged at the bottom of the seamless feeding trough drives the magnetic members to move, thereby adsorbing the small parts in the seamless feeding trough and moving them to the discharge trough along with the rotary line. The magnetic members rotate under the drive of the rotary line and then separate from the small parts, enabling the small parts to slide down along the discharge trough onto the conveyor line of the quenching furnace. This effectively avoids the dropping or jamming of small parts, thus solving the problem of cleaning the feeding assembly when replacing parts for processing, eliminating the quality accidents caused by material mixing, and improving the production efficiency at the same time.

[0025] Please refer to Figure 1 to Figure 2A mesh-belt tempering furnace suitable for small parts is shown in one embodiment of the present application. The mesh-belt tempering furnace includes a quenching furnace 1 and a feeding assembly 2.

[0026] The quenching furnace 1 includes a furnace 11 and a conveyor line 12 that runs through both ends of the furnace 11. A heating component 14 and a hot air circulation component 13 are arranged in the furnace 11 to enable the temperature in the furnace 11 to quickly reach a specified temperature and ensure the uniformity of the temperature in the furnace 11. The conveyor line 12 includes a motor, a guide wheel and a conveyor mesh belt. The motor is arranged outside the furnace 11. The conveyor mesh belt is driven by the motor to rotate and move on the guide wheel, so that the parts are continuously sent into the furnace 11 for heat treatment or the parts are sent out of the furnace 11 after the heat treatment is completed for subsequent process operations. This is a prior art and will not be described in detail here.

[0027] The feeding assembly 2 is arranged at the feeding end of the furnace 11 and docked with the conveyor line 12 to convey the small parts to the quenching furnace 1. The feeding assembly 2 includes a seamless feeding trough 21, a turntable 22 arranged at the bottom of the seamless feeding trough 21, and a plurality of magnetic parts 23 arranged at intervals on the turntable 22. Among them, the seamless feeding trough 21 is made of non-magnetic metal material, and there is no gap, so as to prevent the small parts from falling. When the turntable 22 rotates at the bottom of the seamless feeding trough 21, it drives the magnetic suction parts to move along the length direction of the seamless feeding trough 21, so as to absorb the small parts in the seamless feeding trough 21, and drive the small parts from one end of the seamless feeding trough 21 to the other end under the action of the turntable 22, which can effectively prevent the small parts from being retained in the seamless feeding trough 21. In addition, due to the interval arrangement of the magnetic suction parts, a batch of small parts can be separated into several groups, and the number of each group is roughly equal, which can effectively break up the small parts, avoid the accumulation of a large number of small parts, and make them heated evenly.

[0028] A discharge chute 24 is obliquely arranged at the end of the seamless loading chute 21, and the angle between the seamless loading chute 21 and the discharge chute 24 is an acute angle. Under the action of the magnetic part 23, the small parts move from the seamless loading chute 21 to the discharge chute 24, and separate from the magnetic part 23 to slide along the discharge chute 24 to the conveyor line 12. The connection between the discharge chute 24 and the seamless loading chute 21 is an arc-shaped connecting groove, and the end of the rotating line 22 is set at the arc-shaped connecting groove, so that when the rotating line 22 rotates and moves in the arc-shaped connecting groove, it drives the small parts from the seamless loading chute 21 through the arc-shaped connecting groove to the inclined discharge chute 24. The rotating line 22 continues to rotate and move so that the magnetic part 23 is away from the discharge chute 24, so that the suction force of the magnetic suction part on the small parts is insufficient to adsorb the small parts in the discharge chute 24. Under the action of their own gravity, the small parts slide along the discharge chute 24 to the conveyor line 12, and are conveyed by the conveyor line 12 to the furnace 11 for heat treatment.

[0029] In this embodiment, the seamless loading chute 21 includes a horizontal section 211 and an inclined section 212 connected to the end of the horizontal section 211. The inclined section 212 is disposed close to the conveyor line 12 and partially located above the conveyor line 12. The rotary line 22 is disposed below the inclined section 212 and is consistent with the inclined direction of the inclined section 212. Small parts are placed on the horizontal section 211 manually or by other automated devices and pushed to the connection between the horizontal section 211 and the inclined section 212. The rotary line 22 drives the magnetic member 23 to rotate, thereby adsorbing a part of the small parts and moving from the bottom of the inclined section 212 to the discharge chute 24 at the top. During this process, for some small parts that may be unstablely adsorbed by the magnetic member 23, they may be separated from the magnetic adsorption member and will fall back to the bottom of the inclined section 212 under their own gravity, avoiding the retention of small parts on the inclined section 212.

[0030] In this embodiment, the seamless loading chute 21 has a U-shaped structure with an upward opening. The upward-opening U-shaped structure enables the loading path of the small parts to be a seamless channel, avoiding the small parts from falling during the loading process. Of course, the seamless loading chute 21 can also be of other shapes, such as an open U-shaped structure or a constricted U-shaped structure, etc., as long as the above effects can be achieved.

[0031] The rotary line 22 includes an upper roller 222 and a lower roller 221 respectively disposed at both ends of the inclined section 212, a rotary belt 223 connected between the upper roller 222 and the lower roller 221, and a power member (not shown) for driving the upper roller 222 and / or the lower roller 221 to rotate. In this embodiment, the power member is a motor. The motor drives the upper roller 222 to rotate, and then drives the rotary belt 223 to rotate. During this process, the lower roller 221 rotates cooperatively, so as to realize the reciprocating rotary motion of the rotary belt 223. Of course, in other embodiments, the lower roller 221 can also be driven by a motor to rotate as the driving wheel, and the upper roller 222 rotates cooperatively as the driven wheel. Or two synchronous motors are used to drive the lower roller 221 and the upper roller 222 to rotate simultaneously to drive the rotary belt 223 to rotate.

[0032] In this embodiment, the magnetic member 23 extends along the width direction of the rotary belt 223. The magnetic member 23 is a bar magnet, which extends along the width direction of the rotary belt 223 and is equal to the width of the rotary belt 223, so that the magnetic member 23 can adsorb more small parts. At the same time, it is spaced apart from other magnetic members 23 in the length direction of the rotary belt 223, so that a batch of small parts can be grouped and loaded onto the conveyor line 12 for grouped heat treatment. Since the number of small parts adsorbed by the magnetic member 23 each time is limited, the heat treatment effect of each small part in each group can be effectively guaranteed.

[0033] In this embodiment, the discharge chute 24 and the seamless loading chute 21 are integrally formed, and such a configuration can effectively prevent small parts from being stuck in gaps during loading. Of course, in other embodiments, the discharge chute 24 and the seamless loading chute 21 are also separately configured, and when the discharge chute 24 and the seamless loading chute 21 are docked and installed, the end of the discharge chute 24 is connected to the bottom of the seamless loading chute 21, so that the gap formed between the two is opposite to the conveying direction of small parts, thereby also preventing small parts from being stuck in gaps during loading.

[0034] In another embodiment, a pusher is provided at the connection between the horizontal section 211 and the inclined section 212. The pusher is used to push the small parts located in the horizontal section 211 into the inclined section 212. The pusher includes a paddle provided in the seamless feeding trough 21 and a driving member installed outside the seamless feeding trough 21 to drive the paddle to rotate. Since the distance between the magnetic part 23 and the inclined section 212 when rotating is greater than the distance when the magnetic part 23 moves linearly along the inclined section 212, the adsorption force of the magnetic part 23 on the small parts reaches a maximum value when the magnetic part 23 moves linearly along the inclined section 212. By providing the pusher, the small parts can be partially pushed onto the inclined section 212. When the magnetic part 23 moves to the inclined section 212 and moves linearly, the magnetic part 23 can stably adsorb the small parts to a maximum value, thereby improving the feeding efficiency.

[0035] The beneficial effect of the utility model is that the present application realizes an automated loading process by arranging a loading assembly at the feeding end of the quenching furnace, and utilizes a rotating line arranged at the bottom of the seamless loading trough to drive the magnetic part to move, thereby adsorbing small parts in the seamless loading trough and moving the magnetic part to the unloading trough along the rotating line. The magnetic part rotates under the drive of the rotating line and then separates from the small parts, so that the small parts slide along the unloading trough to the conveyor line of the quenching furnace, thereby effectively avoiding the small parts from falling or getting stuck, thereby solving the problem of needing to clean the loading assembly when replacing parts, eliminating quality accidents caused by mixing, and improving production efficiency at the same time.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
