Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of excavator bucket teeth, in particular to a heat treatment process and heat treatment equipment for excavator bucket teeth. Background Art

[0002] As an important piece of engineering machinery, excavators play a very important role in economic construction. Excavator bucket teeth are important components of excavators, similar to human teeth. They are in direct contact with materials such as ore, rock, sand, etc. during use and are vulnerable parts. The processing process of excavator bucket teeth is to perform heat treatment after forging. In the heat treatment process, the forged excavator bucket is cleaned and loaded into a charging furnace. The excavator bucket teeth are heated and carburized by the charging furnace, and then placed in a quenching tank for cooling and quenching.

[0003] In the prior art, the process of transferring the excavator bucket teeth from the charging furnace into the quenching pool is as follows: after opening the furnace cover of the charging furnace, the bottom plate of the charging furnace is directly lifted up, so that the excavator bucket teeth on the bottom plate of the charging furnace slide into the quenching pool. During this process, the excavator bucket teeth sent into the quenching pool are easily accumulated in one area and cannot be dispersed in the quenching pool. The excavator bucket teeth cannot fully contact the cooling medium, resulting in uneven cooling of the excavator bucket teeth, which affects the performance of the excavator bucket teeth.

[0022] S3. The weight of the excavator bucket teeth in each transfer trough is monitored by a weighing sensor.

[0027] 1.

The excavator bucket teeth are first dispersed through several distribution channels and then enter the corresponding transfer troughs. The weight of the excavator bucket teeth in the transfer troughs is monitored in real time. After it is detected that the set weight in the transfer trough is reached, the corresponding distribution channel is closed, and the excavator bucket teeth are continuously transported to other transfer troughs through other distribution channels, so that the number of excavator bucket teeth in each transfer trough is closer, thereby making the excavator bucket teeth subsequently sent to the quenching pool more evenly dispersed.

[0028] 2. The heat treatment process and equipment for excavator bucket teeth: the transfer chute that reaches the set weight moves into the quenching pool through the guide rail, and the excavator bucket teeth are transported to the quenching pool. A stop frame is set in the quenching pool to stop the transfer chute. The stop frame corresponding to each transfer chute is set in a stepped shape, so that the height and front and rear positions of all transfer chute sliding into the quenching pool are different, so that the excavator bucket teeth entering the quenching pool can be further dispersed, reducing accumulation, thereby reducing the possibility of uneven cooling of the excavator bucket teeth and ensuring the overall performance of the excavator bucket teeth.

[0029] 3. The heat treatment process and equipment for excavator bucket teeth are equipped with a ejection plate at the stop frame. When the transfer trough is in contact with the stop frame, the sealing plate at the bottom of the transfer trough is first opened to remove the excavator bucket teeth from the quenching pool in the transfer trough. Then, the ejection plate is unlocked, causing the ejection plate to pop out and impact the excavator bucket teeth that fall from the transfer trough, further promoting the dispersion of the excavator bucket teeth, reducing the accumulation of the excavator bucket teeth, and improving the uniformity of the cooling of the excavator bucket teeth, thereby further ensuring the processing performance of the excavator bucket teeth.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] For example 1, please refer to Figures 1 to 11 , an excavator bucket tooth heat treatment equipment, including a quenching tank 1, a quenching tank 1 is provided with a distribution trough 2 on one side, the distribution trough 2 is divided into a number of distribution channels 4 at equal intervals by a partition 3, the lower end of the distribution trough 2 is inclined with a number of guide rail groups, the guide rail group includes two groups of guide rails 5, the guide rails 5 extend into the quenching tank 1, each guide rail group is slidably provided with a transfer trough 6, the transfer trough 6 corresponds to the distribution channel 4 one by one, and a connecting block 7 is fixed on both sides of the transfer trough 6 and corresponding to the guide rail 5, a slider 8 is slidably provided on the guide rail 5, and a weighing sensor 9 is installed between the slider 8 and the connecting block 7;

[0044] Magnetic blocks 10 are fixed on both sides of the transfer trough 6, and an electromagnet 11 is installed at the lower end of the distribution trough 2 and at the position corresponding to the magnetic block 10;

[0045] The partition plate 3 is provided with openings 12 , and adjacent openings 12 are arranged in a staggered manner. A blocking and flow guiding mechanism is provided in the material distribution channel 4 .

[0046] A support frame 13 is fixedly provided at the lower end of the distribution trough 2 . A connecting frame 14 is fixedly provided on the side of the support frame 13 facing the guide rail group. The connecting frame 14 is fixedly connected to the end of the guide rail 5 located at the lower end of the distribution trough 2 .

[0047] Several groups of intercepting frames 15 are provided in the quenching tank 1. The intercepting frames 15 correspond to the guide rail groups one by one and are fixedly connected to the ends of the guide rail groups extending into the quenching tank 1. The several groups of intercepting frames 15 are arranged in a stepped manner.

[0048] A guide hopper 16 is provided on the side of the distribution trough 2 away from the quenching tank 1 , and two sets of guide slopes 17 are symmetrically provided on the side wall of the opening 12 facing the quenching tank 1 and the side wall of the partition 3 away from the quenching tank 1 .

[0049] Among them, the blocking and diversion mechanism includes a guide plate 18 and a motor 19. The guide plate 18 is arranged in the distribution channel 4, and the motor 19 is installed at the lower end of the distribution trough 2. The output shaft of the motor 19 is fixedly connected to the lower end surface of the guide plate 18.

[0050] More specifically, in this embodiment: in the initial state, the guide plate 18 is parallel to the partition plate 3 and does not hinder the downward movement of the excavator bucket teeth;

[0051] During operation, the guide hopper 16 connected to the distribution trough 2 is aligned with the charging furnace, and the carburized excavator bucket teeth are sent to the guide hopper 16, so that the excavator bucket teeth are dispersed into each distribution channel 4, and then slide into each transfer trough 6. The weight of the excavator bucket teeth in each transfer trough 6 is monitored by the weighing sensor 9. When it is monitored that the weight in the transfer trough 6 reaches the set value, that is, when the transfer trough 6 is full, the blocking and diversion mechanism in the distribution channel 4 corresponding to the transfer trough 6 is operated. If the transfer troughs 6 on both sides reach the set weight, the guide plate 18 is driven to rotate by the motor 19 so that the guide plate 18 faces one end of the quenching pool 1 Rotate toward the opening 12 until the guide plate 18 rotates toward one end of the quenching pool 1 to the middle of the opening 12, and the end of the guide plate 18 away from the quenching pool 1 contacts the side wall of the distribution trough 2. At this time, the guide plate 18 closes the distribution channel 4, and the guide plate 18 is in an inclined state, so that the excavator bucket teeth in the distribution channel 4 are guided to the opening 12 by the guide plate 18, and further enter other distribution channels 4; if the transfer trough 6 in the middle reaches the set weight, it is further determined whether the two adjacent transfer troughs 6 have reached the set weight. If the two adjacent transfer troughs 6 have not reached the set weight, it is determined that the weight of the two adjacent transfer troughs 6 The size of the material distribution channel 4 corresponding to the transfer trough 6 with a small weight is identified as the channel to be diverted, and the opening 12 connected to the channel to be diverted in the material distribution channel 4 corresponding to the transfer trough that has reached the set weight is identified as the opening to be diverted, and the blocking and diversion mechanism corresponding to the opening to be diverted in the material distribution channel 4 corresponding to the middle transfer trough 6 is driven to operate, and the guide plate 18 closes the material distribution channel 4 corresponding to the middle transfer trough 6, and diverts the excavator bucket teeth to the opening to be diverted, thereby diverting the water to the channel to be diverted; if the two adjacent transfer troughs 6 have reached the set weight, the blocking mechanism away from the quenching pool 1 in the material distribution channel 4 corresponding to the middle transfer trough 6 is driven. The diversion mechanism is operated, and the guide plate 18 closes the distribution channel 4 corresponding to the middle transfer trough 6, so as to minimize the excavator bucket teeth from entering the distribution channel 4 corresponding to the middle transfer trough 6; if one of the two adjacent transfer troughs 6 reaches the set weight and the other does not reach the set weight, the blocking and diversion mechanism corresponding to the opening in the distribution channel 4 corresponding to the middle transfer trough 6 connected to the distribution channel 4 corresponding to the transfer trough 6 that has not reached the set weight is driven to operate, and the guide plate 18 closes the distribution channel 4 corresponding to the middle transfer trough 6, and diverts the excavator bucket teeth to the distribution channel 4 corresponding to the transfer trough 6 that has not reached the set weight;

[0052] When the weight of the transfer trough 6 reaches the set value, the material distribution channel 4 corresponding to the transfer trough 6 is closed, and the electromagnet 11 corresponding to the transfer trough 6 is de-energized, so that the electromagnet 11 loses its adsorption force on the magnetic block 10 connected to the transfer trough 6, thereby releasing the fixation of the transfer trough 6. Due to the inclined setting of the guide rail group, the transfer trough 6 slides into the quenching pool 1 under the action of gravity until the transfer trough 6 contacts the stop frame 15, and the transfer trough 6 is stopped by the stop frame 15, so that the transfer trough 6 stays in the quenching pool 1. The several stop frames 15 in the quenching pool 1 are arranged in a stepped shape, so that the front and rear positions and heights of each transfer trough 6 after sliding into the quenching pool 1 are different, so that the excavator bucket teeth entering the quenching pool 1 can be dispersed, reducing accumulation, reducing the possibility of uneven cooling of the excavator bucket teeth, and ensuring the overall performance of the excavator bucket teeth.

[0053] Example 2: This example is an improvement based on Example 1. This example is intended to help solve the problem of how to achieve excavator bucket tooth unloading. For details, please refer to Figures 1 to 9 , two sets of sealing plates 20 are hinged at the lower end of the transfer trough 6, and two sets of first guide rods 21 are fixed on both sides of the transfer trough 6. Side plates 22 are slidably provided on the two sets of first guide rods 21. A transverse plate 23 is fixed at the lower end of the side plate 22, and balls 24 are evenly distributed on the upper end of the transverse plate 23. A limit plate 25 is fixed at one end of the two sets of first guide rods 21 away from the transfer trough 6. A first spring 26 is connected between the limit plate 25 and the transfer trough 6 and located on the outside of the first guide rod 21;

[0054] A first connecting rod 27 is fixed to one end of the transverse plate 23 facing the quenching tank 1 , and a first wedge block 28 is fixed to one end of the first connecting rod 27 away from the transverse plate 23 ;

[0055] A second connecting rod 29 is fixed on the intercepting frame 15, and a push block 30 is fixed on the end of the second connecting rod 29 away from the intercepting frame 15. The push block 30 is located between the two groups of first wedge blocks 28, and inclined surfaces are provided on both sides of the push block 30 to match the first wedge blocks 28. The thickness of the push block 30 is greater than the thickness of the first wedge blocks 28.

[0056] More specifically, in this embodiment, when the first spring 26 is in its original state, the cross plate 23 and the ball bearing 24 are located at the lower end of the sealing plate 20, limiting and locking the sealing plate 20 so that the sealing plate 20 remains horizontal and blocks the bottom of the transfer slot 6. Since the guide rail 5 is tilted, the transfer slot 6 drives the first wedge block 28 to slide tiltedly. Therefore, the thickness of the push block 30 is set to be greater than that of the first wedge block 28, so that the first wedge block 28 will not be misaligned during the contact process with the push block 30.

[0057] During the process of the transfer trough 6 sliding toward the stop frame 15 in the quenching pool 1, when the first wedge block 28 moves to the push block 30 and continues to move, the push block 30 will form an extrusion force on the first wedge block 28, squeezing the two groups of first wedge blocks 28 to both sides, thereby causing the side plate 22, the cross plate 23 and the ball 24 to move outward until the cross plate 23 moves from the lower end of the transfer trough 6 to the outside of the transfer trough 6. At this time, the sealing plate 20 loses its restriction and is opened under the action of the gravity of the excavator bucket teeth, and the excavator bucket teeth slide from the transfer trough 6 into the quenching pool 1.

[0058] Example 3: This example is an improvement based on Example 2. This example is intended to solve the problem of bucket teeth of excavators piling up after falling from the transfer chute 6 and landing in the same position. For details, please refer to Figures 1 to 9 , two sets of second guide rods 31 are slidably provided on the intercepting frame 15, and a projection plate 32 is fixedly provided on the side of the second guide rod 31 facing the material distribution trough 2. A second spring 33 is connected between the projection plate 32 and the intercepting frame 15 and on the outside of the second guide rod 31. A second limiting plate 34 is fixedly provided on one end of the two sets of second guide rods 31 away from the projection plate 32;

[0059] A support plate 35 is fixed on the stopping frame 15, and two groups of third guide rods 36 are slidably provided on the support plate 35. A third limiting plate 43 is fixed to the lower ends of the two groups of third guide rods 36. A third spring 44 is connected between the third limiting plate 43 and the support plate 35 and on the outside of the third guide rod 36. A moving block 37 is fixed to the upper ends of the two groups of third guide rods 36. A wedge-shaped surface 38 is provided in the middle of the lower end of the moving block 37. A locking plate 42 is fixed to the end of the moving block 37 away from the material distribution trough 2, and the locking plate 42 is in an inverted L shape. A second wedge block 39 is fixed to the side wall of the transfer trough 6 facing the quenching pool 1, and the second wedge block 39 corresponds to the wedge surface 38.

[0060] More specifically, in this embodiment, in the initial state, the locking plate 42 extends into the front side of the second limiting plate 34 to limit the second limiting plate 34, and the second spring 33 is in a compressed state; the angle of the inclined surface of the second wedge block 39 and the angle of the wedge surface 38 are both greater than the inclination angle of the guide rail 5, so that when the second wedge block 39 moves downwardly along the transfer slot 6, the second wedge block 39 can still push the moving block 37 to move upward;

[0061] In the process of the transfer trough 6 sliding toward the stop frame 15 in the quenching tank 1, the transfer trough 6 drives the second wedge block 39 to move, and the second wedge block 39 gradually moves toward the wedge surface 38 at the lower end of the moving block 37. When the second wedge block 39 moves to the wedge surface 38, the second wedge block 39 continues to move, and the second wedge block 39 pushes the moving block 37 to move upward, thereby driving the locking plate 42 to move upward until the locking plate 42 completely moves to the upper end of the second limit plate 34. At this time, the second limit plate 34 is lost. The restriction is removed, so that the second spring 33 loses its limiting force, and the second spring 33 rebounds and resets, thereby driving the ejection plate 32 to pop out toward the lower end of the transfer trough 6. The ejection plate 32 pops out after the sealing plate 20 is opened. Therefore, in the process of the ejection plate 32 popping out, it impacts the excavator bucket teeth falling from the transfer trough 6, prompting the excavator bucket teeth to disperse and reduce the accumulation of the excavator bucket teeth; in the specific setting, a protective cover can be set at the upper end of the quenching pool 1 to prevent the excavator bucket teeth from flying out of the quenching pool.

[0062] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 1 to 10 A plurality of third wedge blocks 40 are distributed on a side of the ejection plate 32 away from the second guide rod 31 , and the third wedge blocks 40 are arranged at different angles.

[0063] More specifically, in this embodiment: when the ejection plate 32 is ejected, the third wedge blocks 40 at different angles can cause the excavator bucket teeth to disperse in different directions when hitting the excavator bucket teeth, thereby further improving the uniform dispersion of the excavator bucket teeth in the quenching pool 1, reducing the accumulation of the excavator bucket teeth, and improving the uniformity of the excavator bucket teeth cooling, thereby further ensuring the processing performance of the excavator bucket teeth.

[0064] Example 5: This example is an improvement made on the basis of Example 3. For details, please refer to Figures 1 to 9 and Figure 11 A plurality of hemispherical blocks 41 are distributed on a side of the ejection plate 32 away from the second guide rod 31 , and the diameters of the hemispherical blocks 41 are different.

[0065] More specifically, in this embodiment: during the ejection process of the ejection plate 32, the hemispherical blocks 41 of different diameters contact the excavator bucket teeth at different positions when hitting the excavator bucket teeth, prompting the excavator bucket teeth to disperse to different positions, thereby further improving the uniform dispersion of the excavator bucket teeth in the quenching pool 1, reducing the accumulation of the excavator bucket teeth, and improving the uniformity of the excavator bucket teeth cooling, thereby further ensuring the processing performance of the excavator bucket teeth.

[0066] The present invention also provides a heat treatment process for excavator bucket teeth, comprising the following steps:

[0067] S1. Clean the excavator bucket teeth and load them into a charging furnace, and then carburize the excavator bucket teeth through the charging furnace;

[0068] S2, align the guide hopper 16 connected to the distribution trough 2 with the charging furnace, and send the carburized excavator bucket teeth to the guide hopper 16, so that the excavator bucket teeth are dispersed into each distribution channel 4, and then slide into each transfer trough 6;

[0069] S3. The weight of the excavator bucket teeth in each transfer trough 6 is monitored by the weighing sensor 9. When the weight in the transfer trough 6 reaches the set value, the blocking and diversion mechanism in the distribution channel 4 corresponding to the transfer trough 6 with the weight reaching the set value is activated to close the distribution channel 4 and guide the excavator bucket teeth through the opening 12 to other distribution channels 4. At this time, the electromagnet 11 corresponding to the transfer trough 6 is de-energized, losing the attraction force on the magnetic block 10, so that the transfer trough 6 slides through the guide rail 5 into the quenching tank 1;

[0070] S4: When the transfer chute 6 slides toward the quenching pool 1 and contacts the stop frame 15, the sealing plate 20 is first unlocked, so that the sealing plate 20 is opened under the gravity of the excavator bucket teeth, and the excavator bucket teeth slide from the transfer chute 6 into the quenching pool 1;

[0071] S5. Then, the ejection plate 32 is unlocked, and the ejection plate 32 pops out, breaking up the excavator bucket teeth, so that the excavator bucket teeth are more evenly dispersed;

[0072] S6. The excavator bucket teeth are rapidly cooled in the quenching tank 1.

[0073] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0074] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
