Description

Technical Field

[0001] This utility model relates to the field of chain technology, specifically to a carbonizing treatment of the surface of a pin sleeve for a mud scale machine chain. Background Technology

[0002] In existing carburizing treatment technology for the pin sleeves of mud scale machine chains, the operation is usually carried out manually or semi-automatically. This method has several shortcomings.

[0003] Firstly, during the carburizing process, the placement of the pin sleeves and the introduction of the carburizing agent often rely on manual operation. This not only increases the complexity of the operation but may also lead to uneven carburizing. Due to the errors and uncertainties of manual operation, it is difficult to ensure that each pin sleeve achieves a consistent carburizing effect, thus affecting the quality and performance of the product.

[0004] Secondly, existing carburizing equipment typically lacks continuity and automation, resulting in low production efficiency. Numerous manual steps are not only time-consuming and labor-intensive but also prone to human error and safety hazards. Furthermore, the discontinuous nature of the process makes large-scale, high-efficiency production difficult to achieve.

[0005] Furthermore, the uniformity and quality of the carburized layer are also challenges in existing technologies. Insufficient or uneven contact between the carburizing agent and the pin sleeve often leads to inconsistent thickness and distribution of the carburized layer, thus affecting the product's service life and performance. This problem is particularly prominent when processing pin sleeves with complex shapes or large dimensions. Utility Model Content

[0006] In order to solve the problems mentioned in the background art, the present invention provides a surface carburizing treatment for the pin sleeve of the chain of a mud scale machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A surface carburizing treatment method for a chain pin sleeve of a mud scale machine includes a housing, servo motors, a carburizing chamber, and a heating device. The housing has a door at the top. Two servo motors are fixedly connected to the side walls of the housing. A drive rod is fixedly connected to the drive end of each servo motor. A bending rod is fixedly connected to the end of each drive rod away from the servo motor. Both bending rods are located inside the housing and are symmetrically arranged. A rotating rod is fixedly connected to the end of each bending rod away from the drive rod. The central axes of the two rotating rods are on the same oblique line. A material box, cylindrical in shape, is housed inside the housing. An opening is provided at the top of the material box. Both sides of the box are fixedly connected with fixed sleeves, which are fitted onto the outer surface of the rotating rod. A material plate is rotatably engaged inside the material box. The center of each side wall of the material plate is fixedly connected to the end of the two rotating rods away from the bending rod. Multiple material grooves are opened on the outer surface of the material plate. A conduit is connected through the bottom of the material box. The carburizing box is fixedly connected to the inner bottom wall of the box body. A telescopic hose is provided on the top of the carburizing box and is connected to the conduit. Two fixed plates are fixedly connected inside the box body. The fixed plates are located below the material box. Two heating devices are symmetrically installed on the top of the fixed plates. The material box is located between the two heating devices.

[0009] Furthermore, fan blades are fixedly connected to both the upper and lower surfaces of the drive rod, and the two sets of fan blades are located on both sides of the material box.

[0010] Furthermore, the conduit is slidably engaged between two fixed plates, and the conduit is located between two heating devices.

[0011] Furthermore, the material plate is cylindrical in shape, and the multiple material slots are distributed in a circular array.

[0012] Furthermore, the tip of the conduit is located directly below one of the material troughs.

[0013] Furthermore, the top opening of the material box is located directly below the box door.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a servo motor to precisely control the circumferential rotation of the material plate, ensuring that each material tank passes through the carburizing agent inlet position sequentially, thereby achieving efficient and uniform carburizing treatment of the pin sleeve. This design greatly improves the efficiency and consistency of the carburizing process.

[0016] 2. This invention integrates multiple steps, including material placement, carburizing agent introduction, heating, and accelerated airflow, achieving continuity and automation of the entire carburizing process through mechanization. This reduces the complexity of manual operation and improves production efficiency and safety.

[0017] 3. By combining the circular rotation of the material plate with the reciprocating oscillation of the material box, this invention ensures that the pin sleeve can make more comprehensive contact with the carburizing agent. This design not only improves carburizing efficiency but also significantly enhances the uniformity and quality of the carburized layer. Attached Figure Description

[0021] Example

[0022] Please see Figure 1-2A surface carburizing treatment method for a chain pin sleeve of a mud scale machine includes a housing 1, a servo motor 3, a carburizing box 11, and a heating device 14. The top of the housing 1 has a door 2. Two servo motors 3 are fixedly connected to the two side walls of the housing 1. A drive rod 4 is fixedly connected to the drive end of each servo motor 3. A bending rod 6 is fixedly connected to the end of the drive rod 4 away from the servo motor 3. Both bending rods 6 are located inside the housing 1 and are centrally symmetrically arranged. A rotating rod 7 is fixedly connected to the end of the bending rod 6 away from the drive rod 4. The central axes of the two rotating rods 7 are on the same oblique line. A material box 8 is provided inside the housing 1. The material box 8 is cylindrical in shape and has an opening at the top. Both side walls of the material box 8 are penetrating... A fixed sleeve 9 is fixedly connected to the material box 8 and is fitted onto the outer surface of the rotating rod 7. A material plate 15 is rotatably engaged inside the material box 8. The center positions of the two side walls of the material plate 15 are fixedly connected to the ends of the two rotating rods 7 away from the bending rod 6, respectively. Multiple material grooves 16 are opened on the outer surface of the material plate 15. A conduit 10 is connected through the bottom of the material box 8. A carburizing box 11 is fixedly connected to the inner bottom wall of the box body 1. A telescopic hose 12 is provided on the top of the carburizing box 11 and is connected to the conduit 10. Two fixed plates 13 are fixedly connected inside the box body 1. The fixed plates 13 are located below the material box 8. Two heating devices 14 are symmetrically installed on the top of the fixed plates 13. The material box 8 is located between the two heating devices 14.

[0023] The drive rod 4 has fan blades 5 fixedly connected to both its upper and lower surfaces, and the two sets of fan blades 5 are located on both sides of the material box 8. This design significantly enhances airflow within the box 1. The increased airflow speed helps the pin sleeve within the material tank 16 to be heated evenly, thereby improving the uniformity and consistency of the carburizing process. At the same time, the uniform heating environment helps reduce thermal stress during the carburizing process and lowers the risk of workpiece deformation.

[0024] The conduit 10 is slidably engaged between two fixed plates 13 and located between two heating devices 14. This design limits the position of the conduit 10 by the two fixed plates 13, thus restricting the movement trajectory of the material box 8, allowing the servo motor 3 to drive the rotating rod 7 to reciprocate the material box 8.

[0025] The material plate 15 is cylindrical in shape, with multiple material slots 16 arranged in a circular array. This design allows the material plate 15 to make full use of space, accommodating more pin sleeves for simultaneous carburizing. Furthermore, as the material plate 15 rotates smoothly, each material slot 16 passes through the carburizing agent introduction position in sequence, thus achieving efficient carburizing.

[0026] The top of the conduit 10 is located directly below one of the material tanks 16. This design ensures that the carburizing agent can be precisely introduced into the material tank 16 and make full contact with the pin sleeve. This precise positioning helps to achieve uniformity and consistency of the carburized layer, improving the quality of carburizing.

[0027] The top opening of the material box 8 is located directly below the door 2, a design that makes it easy for the operator to insert the pin sleeve into the material trough 16.

[0028] The working principle of this utility model is as follows: When using the chain pin sleeve of the mud scale board machine for surface carburizing, the operator first prepares multiple pin sleeves to be carburized through the box door 2 at the top of the box 1. At this time, the material plate 15 in the material box 8 is in a stationary state, and it is provided with multiple material grooves 16 arranged in a circular array, each material groove 16 for accommodating one pin sleeve. The servo motor 3, as the core power source of the entire system, starts and precisely transmits rotational power to the bending rod 6 through the drive rod 4. After receiving the rotational power, the bending rod 6 begins to rotate in a circle. The rotation of the bending rod 6 further drives the rotating rod 7 connected to it to rotate. The rotating rod 7 is connected to the material plate 15 in the material box 8. Therefore, when the rotating rod 7 rotates, it can drive the material plate 15 to rotate smoothly in a circle in the material box 8. As the material plate 15 rotates smoothly, the multiple material grooves 16 on it will pass through the opening at the top of the material box 8 in sequence. At the top opening of the material box 8, the operator can sequentially place the prepared pin sleeves into the material troughs 16. Since the material plate 15 rotates, each material trough 16 passes through the top opening of the material box 8, ensuring that all pin sleeves are placed evenly and orderly into multiple material troughs 16. The telescopic hose 12 serves as a conveying channel, precisely guiding the carburizing agent from the carburizing box 11 into the conduit 10 at the bottom of the material box 8. The design of the conduit 10 ensures that the carburizing agent flows evenly and stably into the material box 8. The top of the conduit 10 is located directly below a specific material trough 16 on the material plate 15. As the material plate 15 rotates, each material trough 16 is sequentially positioned directly below the conduit 10, ensuring full contact between the carburizing agent and the pin sleeves within that material trough 16, achieving efficient carburizing treatment. A heating device 14 mounted on the fixed plate 13 heats the pin sleeves within the material box 8. This heating process helps accelerate the carburizing reaction, improving carburizing efficiency and quality. The servo motor 3 not only drives the material plate 15 to rotate via the rotating rod 7, but also, due to the linkage between the bending rod 6 and the rotating rod 7, causes the material box 8 to oscillate reciprocally under the drive of the rotating rod 7. This combined motion of oscillation and rotation ensures that the pin sleeve in the material tank 16 can make more comprehensive contact with the carburizing agent, further improving the carburizing effect. While driving the drive rod 4 to rotate, the servo motor 3 also drives the fan blade 5 on the drive rod 4 to rotate. The rotation of the fan blade 5 accelerates the airflow speed inside the box 1, which helps the pin sleeve in the material tank 16 to be heated evenly, thereby improving the uniformity and consistency of the carburizing process.
