Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of heat treatment equipment, and in particular relates to a heat treatment system for annular parts. Background Art
[0002] In the heat treatment process, annular parts are usually placed on a tray-type transfer carrier in a horizontal stacking or vertical arrangement, and then the carrier is used to send the annular parts into the heat treatment equipment. However, the existing carriers and heat treatment equipment lack the function of adjusting the position of the parts when performing heat treatment processing on the annular parts. The annular parts are usually in a static state during heat treatment. In order to improve the efficiency of heat treatment and reduce costs, the arrangement density of the parts is usually increased. In addition, the heating components of the heat treatment equipment are usually set on the side walls of the heat treatment equipment. This will cause uneven heating of the parts locally, reducing the overall heat treatment effect of the parts. Summary of the invention
[0003] In order to solve the deficiencies in the prior art, the present invention provides a circular ring part heat treatment system, which can rotate the circular ring part during the heat treatment process, and can effectively improve the overall heat treatment effect of the part.
[0004] In order to achieve the purpose of the present invention, the following scheme is proposed: A heat treatment system for circular ring parts, comprising: a kiln and a tray, characterized in that: The pallet includes a square bottom plate, with positioning holes provided at the same positions around the bottom plate, a plurality of columns vertically passing through the top of the bottom plate, the outer diameter of the columns being smaller than the inner diameter of the circular ring parts, and the lower ends of all the columns being connected by the same chain; the tops of the columns are coaxially provided with connecting holes; the columns are provided with multiple layers of supporting components at intervals along the vertical direction for placing the circular ring parts, and the circular ring parts are in a horizontal state when placed, and the circular ring parts are coaxial with the columns; Tracks are laid inside the kiln for transferring the pallet; a driving shaft is passed downward from the top of the kiln, and the lower end of the driving shaft is used to match the connecting hole. The driving shaft is arranged to move in the vertical direction and is driven by a motor. Positioning pieces are passed through the side walls of the kiln for connecting the positioning holes. When the positioning piece is inserted into the positioning hole, the connecting hole at the top of one of the columns on the pallet is located directly below the driving shaft.
[0005] The beneficial effect of the present invention is that the present invention utilizes a driving shaft to drive the columns connected thereto to rotate, and drives all the columns on the same tray to rotate through a chain, so that the circular ring parts are in a moving state during the heat treatment process, so that any side of the circular ring parts has an equal opportunity to approach the heating components of the kiln, thereby improving the uniformity of heating at various locations of the circular ring parts and improving the quality of heat treatment.

DETAILED DESCRIPTION
[0017] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] like Figures 1 to 9 As shown, a heat treatment system for circular ring parts includes: a kiln and a tray.
[0019] Specifically, Figure 2 , Figure 3 As shown, the pallet includes a square bottom plate 1, with positioning holes 101 provided at the same positions around the bottom plate 1, and a plurality of columns 11 vertically penetrate the top of the bottom plate 1, and the columns 11 are arranged in a circular array. The outer diameter of the column 11 is smaller than the inner diameter of the circular ring part, and the lower ends of all the columns 11 are connected by the same chain 12, and the chain 12 is used to drive all the columns 11 to rotate synchronously. Specifically, the lower ends of the columns 11 are provided with sprockets 13, and all the sprockets 13 are connected to the same chain 12. As a preferred structure, a receiving cavity is provided at the bottom of the base plate 1, and the chain 12 and the sprocket 13 are both arranged in the receiving cavity below the base plate 1; a connecting hole 111 is coaxially opened at the top of the column 11; the column 11 is provided with multiple layers of supporting components at intervals along the vertical direction for placing annular parts. The annular parts are in a horizontal state when placed, and the annular parts are coaxial with the column 11 to prevent the inner wall of the annular parts from contacting the outer wall of the column 11, thereby affecting the heat treatment effect of the contact portion between the annular parts and the column 11.
[0020] The support assembly has a variety of structural settings: as a preferred structure, the support assembly includes at least three support rods arranged along a circumferential array, the outer ends of the support rods are all tilted downward, and the angle between each support rod and the axis of the column 11 is the same. When placing the annular parts, the lower edge of the inner circle of the parts contacts the support rod. Under the action of the gravity of the annular parts and the tilted structure of the support rod, the annular parts are coaxial with the column 11. This structure can also place annular parts of different diameters, and can ensure that the annular parts are coaxial with the column 11. The support rods and the column 11 of this structure are fixed structures. When loading and unloading the annular parts, the posture of the annular parts needs to be constantly adjusted so that the annular parts can be placed on the support rods below after bypassing the upper support rods. As a further preferred structure, the support rods and the column 11 are set as a detachable structure. Specifically, a mounting hole is opened on the column 11 for inserting the support rods, so that the support rods can be loaded and unloaded at any time, thereby facilitating the loading and unloading of the annular parts. As another preferred structure, the support rod is inserted into the column 11, and the support rod is arranged to move along the insertion direction. When loading and unloading the circular ring parts, it is only necessary to retract the support rod toward the middle of the column 11. This structure is not only convenient for loading and unloading the circular ring parts, but also can adapt to circular ring parts of different sizes. The above schemes all make the circular ring parts coaxial with the column 11 and present a neatly stacked state, which can not only improve the stability during the transfer of the pallet, but also make the circular ring parts and the column 11 have a relatively stable position to prevent the circular ring parts from contacting each other, and to avoid the circular ring parts from contacting the column 11, so as to prevent affecting the consistency of the heat treatment effect of various parts of the circular ring parts. In addition, because the column 11 will rotate around the axis in this scheme, the circular ring parts are arranged coaxially with the column 11, which can improve the stability of the column 11 when rotating.
[0021] Specifically, Figure 1and Figures 4 to 9 As shown, the kiln is paved with tracks for transferring pallets. As a preferred structure, the tracks extend to both ends of the kiln to facilitate the rapid delivery and output of pallets. Both ends of the kiln are provided with furnace doors to facilitate closing the kiln during heat treatment. A drive shaft 21 is passed downward from the top of the kiln, and the lower end of the drive shaft 21 is used to match the connecting hole 111. Specifically, the connecting hole 111 can be set as a spline hole, and the lower end of the drive shaft 21 can be set as a spline shaft matching the spline hole; or the connecting hole 111 can be set as a rectangular hole, and the lower end of the drive shaft 21 can be set as a rectangular head matching the rectangular hole. The drive shaft 21 is arranged to move in the vertical direction. The drive shaft 21 is driven by a motor. Specifically, the motor main shaft and the drive shaft 21 can be fixedly connected, and the motor and the drive shaft 21 can move together in the vertical direction. The motor main shaft and the drive shaft 21 can also adopt a split matching connection structure, the motor is fixed to the top of the kiln, a blind hole is opened at the top of the drive shaft 21, and a keyway is set on the side wall of the blind hole, and a connecting key is set on the outside of the main shaft of the motor, so that the main shaft of the motor is inserted into the blind hole, and the connecting key is matched with the keyway. This structure can also meet the requirements that the drive shaft 21 moves in the vertical direction and is connected to the motor main shaft. The movement of the drive shaft 21 in the vertical direction can be controlled by a cylinder. A bearing is sleeved on the outside of the drive shaft 21, and the outer ring of the bearing is connected to the telescopic shaft of the cylinder. The cylinder is vertically arranged on the top of the kiln. The side wall of the kiln is provided with a positioning member 22 for connecting the positioning hole 101. The positioning member 22 is manually pushed or moved by a cylinder control. Since the positioning holes 101 are provided at the same positions around the bottom plate 1, the tray enters the kiln along any length direction and has a positioning hole 101 that matches the positioning member 22. When the positioning member 22 is inserted into the positioning hole 101, the connection hole 111 at the top of one of the columns 11 on the tray is located directly below the drive shaft 21, that is, the connection hole 111 at the top of one of the columns 11 is coaxial with the drive shaft 21. In this state, the drive shaft 21 is moved downward, so that the lower end of the drive shaft 21 can be connected to the connection hole 111, and then the drive shaft 21 is rotated by the motor, and the drive shaft 21 can drive the column 11 connected thereto to rotate, and drive all the columns 11 on the same tray to rotate through the chain 12, so that the annular part is in a moving state during the heat treatment process, so that any side of the annular part has an equal opportunity to approach the heating component of the kiln, thereby improving the uniformity of heating of the annular part and improving the quality of heat treatment. When the heat treatment is completed, the drive shaft 21 is moved upward, so that the drive shaft 21 can be separated from the connection hole 111, and then the tray can be output through the track.
[0022] Preferably, the drive shaft 21 and the positioning member 22 are arranged in groups, and multiple groups of the drive shaft 21 and the positioning member 22 are provided along the track direction, so as to simultaneously position multiple pallets and drive the columns 11 of multiple pallets, thereby increasing the output of a single batch of the kiln.
[0023] Preferably, Figure 2 , Figure 3 As shown, the support assembly includes at least three channel steels 14 arranged on the outer wall of the column 11 along the circumference array. The cross section of the channel steel 14 is a U-shaped structure with an opening facing upward. The channel steel 14 is perpendicular to the column 11. The ends of the channel steel 14 are hinged with support blocks 15, and the hinge axis is perpendicular to the column 11. The support blocks 15 are located inside the groove of the channel steel 14. When the bottom surface of the support block 15 abuts against the top surface of the bottom plate of the channel steel 14, the bottom surface of the support block 15 is horizontal, and the top surface of the support block 15 is inclined toward the outside of the upper end of the column 11. The top surface of the support block 15 is used to support the lower edge of the inner ring of the circular ring part, and the inclined structure of the top surface of the support block 15 is used to keep the circular ring part coaxial with the column 11. When the support block 15 is swung to the bottom facing upward, the distance between the bottom surface of the support block 15 and the axis of the column 11 is smaller than the inner diameter of the circular ring part, so that the support block 15 can be swung upward when the circular ring part is installed and removed, so that the support block 15 can open the circular ring part, and the support block 15 is hingedly connected to the channel steel 14, so when the circular ring part is taken out upward, the circular ring part can push the support block 15 to swing upward automatically, and there is no need to manually operate the support block 15.
[0024] Preferably, Figure 4 , Figure 5 As shown, the positioning hole 101 is a rectangular structure, and its length direction is consistent with the length direction of the side of the base plate 1. The positioning member 22 is a horizontally arranged flat plate structure, and its width is greater than the length of the positioning hole 101. The two sides of the front end of the positioning member 22 are conical structures, so as to facilitate the cooperation with the positioning hole 101 and improve the positioning accuracy of the tray. When the positioning member 22 is connected to the positioning hole 101, the conical surfaces on both sides of the conical structure are in contact with the two side walls of the length direction of the positioning hole 101 respectively. The above-mentioned structural design of the positioning hole 101 and the positioning member 22 can effectively reduce the requirement for the pallet to stop in the kiln, because the weight of the pallet itself plus the weight of the circular ring parts results in a larger overall weight and a corresponding increase in inertia. Even if a sensor is used to detect the signal that the pallet is in place and then the track is controlled to stop running, the pallet will continue to move forward slightly under the action of inertia, thereby affecting the connection between the positioning member 22 and the positioning hole 101; and with the structural design of this scheme, as long as the cone top at the front end of the positioning member 22 is inserted into the positioning hole 101, the conical surface of the positioning member 22 can be used to push the pallet to the correct position so that one of the connecting holes 111 is located directly below the drive shaft 21.
[0025] Preferably, Figure 5 , Figure 7 and Fig. 9As shown, the positioning member 22 is provided with a strip hole 221 along the insertion direction, and the extension direction of the strip hole 221 is in a vertical state. A push rod 23 is inserted at the end of the positioning member 22, and the push rod 23 is parallel to the insertion direction of the positioning member 22. The rear end of the push rod 23 is connected to a telescopic rod of a telescopic device 24, and the telescopic device 24 is arranged on the outside of the kiln. A baffle 231 is provided in the middle section of the push rod 23, and a cylindrical spring 25 is sleeved on the front end of the push rod 23. The baffle 231 and the cylindrical spring 25 are both located in the strip hole 221, and the cylindrical spring 25 is compressed between the baffle 231 and the front end surface of the strip hole 221. This structure is used to buffer the impact when the positioning member 22 is connected to the positioning hole 101, so that the positioning member 22 can be smoothly inserted into the positioning hole 101 to avoid damage to the positioning surfaces of the positioning member 22 and the positioning hole 101.
[0026] Preferably, Figure 7 , Fig. 9 As shown, a guide hole 222 is opened on the front end surface of the strip hole 221, and the front end of the push rod 23 is inserted into the guide hole 222 to improve the connection stability between the push rod 23 and the positioning member 22 and prevent the push rod 23 from deflecting.
[0027] As a preferred solution, Figure 1 and Figures 4 to 9 As shown, a vertically arranged lifting rod 26 is passed through the top of the corresponding positioning member 22 of the top of the kiln, and a connecting rod 261 is provided at the upper end thereof. The connecting rod 261 is located above the kiln, and a supporting spring 262 is provided between the connecting rod 261 and the top surface of the kiln for providing an upward supporting force to the lifting rod 26. One end of the connecting rod 261 is sleeved on the outside of the driving shaft 21, and the positions of the driving shaft 21 and the connecting rod 261 in the vertical direction remain relatively fixed. As a preferred structure, the outside of the driving shaft 21 is axially connected to the connecting rod 261 to reduce the resistance of the driving shaft 21 during rotation. A pair of parallel guide plates 27 are provided at the lower end of the lifting rod 26, and the two guide plates 27 respectively pass through the intervals between the cylindrical spring 25 and the two sides of the strip hole 221, and the guide plates 27 are located between the baffle 231 and the front end surface of the strip hole 221, and the guide plate 27 has a guide surface 271 on the side facing the baffle 231, and the guide surface 271 is inclined toward the upper side of the rear end of the top rod 23.
[0028] When the positioning piece 22 is connected to the positioning hole 101, the compression of the cylindrical spring 25 is less than one-half of its length. At this time, the lower edge of the front end surface of the baffle 231 contacts the lower end of the guide surface 271, and the lifting rod 26 and the drive shaft 21 are both in the highest position state; when the compression of the cylindrical spring 25 is greater than three-quarters of its length or is fully compressed, the lower edge of the front end surface of the baffle 231 is located at the upper end of the guide surface 271, the lifting rod 26 is in the lowest position state, and the lower end of the drive shaft 21 is inserted into the lower connecting hole 111.
[0029] The purpose of the above structural design is to use the same driving element to control the movement of the positioning member 22 and the driving shaft 21, but the connection between the driving shaft 21 and the connecting hole 111 cannot be achieved synchronously with the positioning of the tray. Therefore, the above scheme is set up, and the positioning member 22 is first connected to the positioning hole 101 to ensure the accuracy of the tray position, and then the driving shaft 21 is inserted. However, in this process, the cylindrical spring 25 is in the initial compression period. At this time, its supporting force is limited and it will inevitably be compressed, which just plays the role of buffering the positioning member 22. By selecting a cylindrical spring 25 with appropriate elasticity, it can be compressed to less than half of the compression state, and there is enough supporting force to drive the positioning member 22 to complete the connection with the positioning hole 101; when the positioning member 22 is connected to the positioning hole 101 Afterwards, the positioning member 22 and the tray are in rigid contact, and the positioning member 22 will not move further; then the telescopic device 24 is used to continue to drive the top rod 23 to move forward, and the baffle 231 can be pushed to continue to move, so that the cooperation between the lower edge of the front end surface of the baffle 231 and the guide surface 271 is utilized to drive the lifting rod 26 to descend, and the driving shaft 21 is driven to descend through the connecting rod 261, so that the driving shaft 21 is connected to the connecting hole 111, and the support spring 262 will be compressed at this time; when the heat treatment is completed, the top rod 23 can be moved backward to separate the baffle 231 from the guide surface 271, and under the action of the support spring 262, the lifting rod 26 and the driving shaft 21 will automatically move upward to the highest position, thereby separating the driving shaft 21 from the connecting hole 111.
[0030] Preferably, Figure 1 and Figure 4 As shown, a spline hole is provided at the top of the driving shaft 21, and driving motors 28 are provided at intervals at the top of the kiln. The purpose of arranging the driving motors 28 at intervals is to reduce the influence of the kiln temperature on the driving motors 28, and at the same time leave enough space for the movement of the driving shaft 21. A spline rod is provided at the lower end of the main shaft of the driving motor 28 for connecting to the spline hole at the top of the driving shaft 21.
[0031] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
