Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a thread rolling device. Background Technology

[0002] Thread rolling technology can improve the internal and surface quality of workpieces. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece, and it is widely used in the threading of stainless steel lead screws. Currently, the feeding equipment of thread rolling equipment includes two cutting mechanisms. The material is transferred sequentially between the two cutting mechanisms to the thread rolling disc. Multiple sensors are installed on the cutting mechanisms to detect the position of the material. The material volume is small, which makes it easy to miss detections. At the same time, the large number of sensors makes the equipment prone to failure and difficult to debug. Utility Model Content

[0003] This application provides a thread rolling device to solve the problem of material mis-detection in existing thread rolling equipment.

[0004] This application embodiment provides a thread rolling device, the thread rolling device comprising:

[0005] First thread rolling plate;

[0006] The second thread rolling disc is capable of moving towards or away from the first thread rolling disc;

[0007] The first thread rolling disc is fixed to the fixed frame;

[0008] A feeding device, comprising a receiving component and a pushing component, wherein the pushing component is located above the receiving component and is movable relative to the receiving component;

[0009] A linkage component, one end of which is connected to the fixed frame and the other end of which is connected to the material feeding component;

[0010] The feeding component includes a first receiving groove, and the receiving component includes a second receiving groove. When the second thread rolling disc moves away from the first thread rolling disc, the receiving component moves relative to the feeding component, and the first receiving groove moves towards the second receiving groove.

[0011] The first receiving tank moves closer to the second receiving tank, allowing the unprocessed material to fall from the first receiving tank into the second receiving tank under the influence of gravity. The material can then be transferred from the second receiving tank to the space between the first and second thread rolling discs. The material feeding process eliminates the need for sensors to detect the position of the unprocessed material, reducing the possibility of sensor oversights preventing the material from being transferred to the space between the first and second thread rolling discs, thus improving the reliability of the feeding process.

[0064] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0065] like Figure 1 and Figure 2 As shown in the figure, this application provides a thread rolling device, including a fixed frame 1, in which a first thread rolling disc 2 and a second thread rolling disc 3 are disposed. The first thread rolling disc 2 and the second thread rolling disc 3 can clamp the material. When the first thread rolling disc 2 and the second thread rolling disc 3 rotate relative to each other, threads can be processed on the surface of the material to improve the internal and surface quality of the material, and improve the fatigue strength and torsional strength of the material.

[0066] The first thread rolling disc 2 is fixed to the fixing frame 1, and the second thread rolling disc 3 can move towards or away from the first thread rolling disc 2. When the second thread rolling disc 3 moves towards the first thread rolling disc 2, the first thread rolling disc 2 and the second thread rolling disc 3 can clamp the material and process threads on the material surface. When the second thread rolling disc 3 moves away from the first thread rolling disc 2, the distance between the first thread rolling disc 2 and the second thread rolling disc 3 increases, and the processed material can fall from the first thread rolling disc 2 and the second thread rolling disc 3. A discharge disc 7 is provided below the first thread rolling disc 2 and the second thread rolling disc 3. The processed material falls into the discharge disc 7 and can be transported along the discharge disc 7 to the thread rolling equipment.

[0067] The thread rolling equipment also includes a feeding device 4, which includes a receiving component 41 and a pushing component 42. The pushing component 42 is located above the receiving component 41 and can move relative to the receiving component 41. The pushing component 42 includes a first receiving groove 421, and the receiving component 41 includes a second receiving groove 411. When the receiving component 41 and the pushing component 42 move relative to each other, the first receiving groove 421 and the second receiving groove 411 can be aligned or staggered. Unprocessed material enters the first receiving groove 421 in the pushing component 42 through the feeding device 5 or manual feeding. When the first receiving groove 421 and the second receiving groove 411 are aligned, the unprocessed material can fall from the first receiving groove 421 into the second receiving groove 411 under the action of gravity.

[0068] like Figure 3 As shown, in one possible embodiment, the cross-sectional area of ​​the second receiving groove 411 gradually increases along the direction close to the first receiving groove 421, so that the cross-section of the second receiving groove 411 is Y-shaped.

[0069] When the receiving component 41 moves with the second thread rolling disc 3 relative to the feeding component 42, the first receiving groove 421 moves closer to the second receiving groove 411. The material located in the first receiving groove 421 will move on the surface of the receiving component 41 towards the second receiving groove 411. When the first receiving groove 421 and the second receiving groove 411 are aligned, the material falls from the first receiving groove 421 into the second receiving groove 411 under the action of gravity. The cross-sectional area of ​​the end of the second receiving groove 411 near the first receiving groove 421 is larger, which facilitates the material falling into the second receiving groove 411.

[0070] The thread rolling equipment also includes a linkage 6, one end of which is connected to a fixed frame 1, and the other end is connected to a material feeding component 42, so that the material feeding component 42 is fixedly installed on the fixed frame 1. A receiving component 41 is movably installed on the fixed frame 1. When the second thread rolling disc 3 moves away from the first thread rolling disc 2, the receiving component 41 can move relative to the material feeding component 42, aligning the second receiving groove 411 with the first receiving groove 421, allowing unprocessed material to fall from the first receiving groove 421 into the second receiving groove 411. The gap between the second receiving groove 411 and the first thread rolling disc 2 and the second thread rolling disc 3 is aligned, allowing unprocessed material to be transferred from the second receiving groove 411 to between the first thread rolling disc 2 and the second thread rolling disc 3. After the second thread rolling disc 3 moves closer to the first thread rolling disc 2, it can clamp the material, and the first thread rolling disc 2 and the second thread rolling disc 3 can process threads on the surface of the material.

[0071] The feeding component 42 moves with the second thread rolling disc 3, allowing unprocessed material to fall from the first receiving groove 421 into the second receiving groove 411. This enables the unprocessed material to be transferred between the first thread rolling disc 2 and the second thread rolling disc 3. The movement of the second thread rolling disc 3 can control the switching of unprocessed material between the feeding component 42 and the receiving component 41. There is no need to use sensors to detect the position of the unprocessed material, which reduces the possibility of sensor misses causing the unprocessed material to fail to be transferred between the first thread rolling disc 2 and the second thread rolling disc 3, thus improving the reliability of the feeding process.

[0072] like Figure 4 As shown, in one possible embodiment, the feeding device 4 includes a base 44 with a recessed portion. Along a direction perpendicular to the relative movement of the receiving member 41 and the pushing member 42, one side of the recess has a side plate 441. The receiving member 41 and the pushing member 42 are sequentially disposed within the recess. The receiving member 41 is fixedly installed on the bottom wall of the recess, and the pushing member 42 is located on the side of the receiving member 41 away from the bottom wall and is movably installed on the side plate 441. A baffle 45 is provided on the side of the recess away from the side plate 441. One side of the receiving member 41 contacts the side plate 441, and the other side contacts the baffle 45.

[0073] Along a direction perpendicular to the relative movement of the receiving member 41 and the pushing member 42, the first receiving groove 421 penetrates the pushing member 42, and the second receiving groove 411 penetrates the receiving member 41. Both the pushing member 42 and the receiving member 41 are disposed within the recess, allowing the side plate 441 and the baffle 45 to respectively block both ends of the first receiving groove 421 and the second receiving groove 411, reducing the possibility of material escaping from the first receiving groove 421 and / or the second receiving groove 411 into the feeding device 4. The portion of the pushing member 42 with the first receiving groove 421 is located between the side plate 441 and the baffle 45, allowing the side plate 441 and the baffle 45 to also restrict the movement direction of the pushing member 42.

[0074] like Figure 4 and Figure 5 As shown, in one possible embodiment, a guide rail 442 is provided on the side plate 441. The guide rail 442 extends along the movement direction of the second thread rolling disc 3. The material feeding member 42 is installed on the guide rail 442 and can restrict the movement direction of the receiving member 41 relative to the material feeding member 42, so that the material feeding member 42 moves relative to the receiving member 41 along the extension direction of the guide rail 442.

[0075] like Figure 4 and Figure 5 As shown, in one possible embodiment, limit plates 443 are provided at both ends of the guide rail 442. When the pusher 42 moves to the end of the guide rail 442, the pusher 42 abuts against the limit plate 443 to restrict the pusher 42 from continuing to move and reduce the possibility of the pusher 42 disengaging from the guide rail 442.

[0076] The feeding device 4 also includes a mounting bracket 48, which is movably mounted on the fixed frame 1 and can move with the second thread rolling disc 3. The base 44 is fixedly mounted on the mounting bracket 48, and the receiving part 41 is fixedly mounted on the base 44, so that the receiving part 41 can move with the second thread rolling disc 3.

[0077] like Figure 3 As shown, the side plate 441 includes a feed hole. When the first thread rolling disc 2 and the second thread rolling disc 3 are clamped together, the first receiving groove 421 is aligned with the feed hole, and unprocessed material can enter the first receiving groove 421 through the feed hole. When the second thread rolling disc 3 moves away from the first thread rolling disc 2, the base 44 moves relative to the material feeding member 42, causing the feed hole to be misaligned with the first receiving groove 421, and the material feeding member 42 can block the feed hole. At this time, unprocessed material cannot enter the feeding device 4 through the feed hole.

[0078] like Figure 3 and Figure 4As shown, in one possible embodiment, a stop block 441a is provided on the side of the side plate 441 facing the recess. When the receiving member 41 moves relative to the pushing member 42 to the stop block 441a abutting the pushing member 42, the receiving member 41 and the pushing member 42 stop moving relative to each other. At this time, the feed hole is aligned with the first receiving groove 421.

[0079] The stop block 441a is provided to limit the movement range of the receiving part 41 relative to the feeding part 42, which facilitates the alignment of the feeding hole with the first receiving groove 421 and can also improve the accuracy of the alignment between the feeding hole and the first groove.

[0080] In one possible embodiment, the length and width of the first receiving groove 421 can be set according to the size of the material, so that the first receiving groove 421 can only hold a single material, which can reduce the possibility of jamming caused by multiple materials in the feeding device 4, and can also reduce the possibility of damage to the material when the receiving member 41 moves to the point where the first receiving groove 421 is misaligned with the feeding hole.

[0081] like Figure 1 and Figure 5 In one possible embodiment, the feeding device 5 can be a vibratory feeder, in which multiple unprocessed materials are placed and orderly fed into the feeding pipe 51 of the feeding device 5. A mounting member 49 is provided on the side plate 441, which clamps the feeding pipe 51, aligning it with the feed inlet, so that the material in the feeding pipe 51 can enter the first receiving groove 421 through the feed inlet.

[0082] like Figure 4 As shown, in one possible embodiment, the baffle 45 includes a discharge hole 451, one end of which is aligned with the second receiving groove 411, and the other end is aligned with the gap between the first thread rolling disc 2 and the second thread rolling disc 3, so that the material in the second receiving groove 411 can be transferred through the discharge hole 451 to the space between the first thread rolling disc 2 and the second thread rolling disc 3.

[0083] like Figure 2 and Figure 6 As shown, in one possible embodiment, the feeding device 4 includes a first pushing member 46 and a second pushing member 47. Both the first pushing member 46 and the second pushing member 47 are fixedly mounted on the mounting bracket 48 and are located on opposite sides of the base 44 along a direction perpendicular to the relative movement of the receiving member 41 and the pushing member 42. The first pushing member 46 is located on one side of the side plate 441 in the base 44, and the second pushing member 47 is located on the side of the base 44 where the baffle 45 is provided.

[0084] The first pushing member 46 includes a first push rod 461 and a first cylinder 462. The first cylinder 462 is fixedly mounted on the mounting bracket 48. The first push rod 461 is connected to the output end of the first cylinder 462, so that the first cylinder 462 can drive the first push rod 461 to move in a direction perpendicular to the relative movement of the receiving member 41 and the pushing member 42. The side plate 441 is provided with a through hole communicating with the second receiving groove 411. The first push rod 461 can extend into the second receiving groove 411 through the through hole to push the material in the second receiving groove 411 out through the discharge hole 451.

[0085] The second pushing member 47 includes a second push rod 471 and a second cylinder 472. The second cylinder 472 is fixedly mounted on the mounting bracket 48 and is located on the side of the second thread rolling disc 3 away from the base 44. The second push rod 471 is mounted on the output end of the second cylinder 472, enabling the second cylinder 472 to drive the second push rod 471 to move in a direction perpendicular to the relative movement of the receiving member 41 and the pushing member 42. The second push rod 471 is aligned with the discharge hole 451 on the baffle 45. After the first push rod 461 pushes the material out of the discharge hole 451, the material can be clamped between the first push rod 461 and the second push rod 471, and the material is transferred between the first thread rolling disc 2 and the second thread rolling disc 3.

[0086] like Figure 6 As shown, in one possible embodiment, the first push rod 461 and / or the second push rod 471 are provided with an elastic structure 463. The elastic structure 463 includes an elastic sleeve and a spring, which allows the first push rod 461 and / or the second push rod 471 to undergo slight deformation along the direction of movement. When the first push rod 461 and the second push rod 471 clamp the material, the possibility of the first push rod 461 and / or the second push rod 471 causing damage to the material can be reduced. It can also reduce the requirement for the precision of the cooperation between the first cylinder 462 and the second cylinder 472.

[0087] In one possible embodiment, the end of the first push rod 461 away from the first cylinder 462 is provided with a first groove, and the end of the second push rod 471 away from the second cylinder 472 is provided with a second groove. When the first push rod 461 and the second push rod 471 clamp the material, one end of the material is located in the first groove and the other end is located in the second groove, which can reduce the possibility of the material falling off.

[0088] like Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the feeding member 42 is provided with a connecting member 43, which protrudes from the side of the feeding member 42 away from the receiving member 41. The connecting member 43 includes a mounting groove 431, the opening of which is located on the side facing the receiving member 41. The linkage member 6 includes a connecting rod 61, which is located within the mounting groove 431 to connect the connecting rod 61 and the feeding member 42.

[0089] like Figure 7 As shown, in one possible embodiment, a first elastic member 611 and a limiting part 612 are sleeved on the connecting rod 61, and the connecting member 43 is located between the first elastic member 611 and the limiting part 612, so that one end of the first elastic member 611 abuts against the connecting member 43 and the other end abuts against the end of the connecting rod 61, thereby limiting the position of the connecting member 43 on the connecting rod 61.

[0090] The user can adjust the position of the limiting part 612 on the connecting rod 61 according to the distance between the fixing frame 1 and the feeding device 4, thereby adjusting the position of the connecting part 43 on the connecting rod 61, and thus controlling the relative position of the feeding part 42 and the receiving part 41. The limiting part cooperates with the limiting plates 443 at both ends of the guide rail 442 to control the distance that the receiving part 41 can move relative to the feeding part 42, so that when the second thread rolling disc 3 is clamped with the first thread rolling disc 2, the first receiving groove 421 on the feeding part 42 is aligned with the feed hole, and when the second thread rolling disc 3 moves away from the first thread rolling disc 2, the first receiving groove 421 is aligned with the second receiving groove 411.

[0091] When the receiving component 41 moves away from the first thread rolling plate 2 along with the second thread rolling plate 3, after the first receiving groove 421 and the second receiving groove 411 are aligned, the feeding component 42 abuts against the limiting plate 443 at one end of the guide rail 442. A first elastic component 611 is provided between the end of the connecting component 43 and the connecting rod 61. If the second thread rolling plate 3 needs to continue to move away from the first thread rolling plate 2, the first elastic component 611 can be compressed, so that both the feeding component 42 and the receiving component 41 can move with the second thread rolling plate 3.

[0092] like Figure 7 As shown, in one possible embodiment, the linkage includes a main body 62, an adjusting rod 63, and a connecting block 64. The main body 62 is connected to the fixing frame 1. The adjusting rod 63 is located between the main body 62 and the connecting block 64, so that the connecting block 64 is connected to the main body 62 through the adjusting rod 63. A second elastic member 631 is sleeved on the adjusting rod 63. One end of the second elastic member 631 abuts against the main body 62, and the other end abuts against the connecting block 64 to limit the distance between the main body 62 and the connecting block 64.

[0093] One end of the adjusting rod 63 can pass through the main body 62, and the adjusting rod 63 has been installed on the main body 62. A pad 66 can be provided between the end of the adjusting rod 63 that passes through the main body 62 and the main body 62. The user can adjust the thickness of the pad 66 according to the distance between the fixing frame 1 and the feeding device 4, thereby adjusting the distance between the connecting block 64 and the main body 62.

[0094] The connecting rod 61 is fixedly installed on the side of the connecting block 64 away from the main body 62. When the second thread rolling disc 3 moves towards the first thread rolling disc 2, the first receiving groove 421 aligns with the feed hole and abuts against the stop block 441a and / or the limiting plate 443. If the first thread rolling disc 2 and the second thread rolling disc 3 do not clamp the material at this time, the second thread rolling disc 3 needs to continue to move towards the first thread rolling disc 2. The second elastic member 631 can be compressed so that the feeding member 42 and the receiving member 41 can move with the second thread rolling disc 3.

[0095] The first elastic element 611 and the second elastic element 631 cooperate so that after the receiving element 41 moves relative to the feeding element 42, it can drive the feeding element 42 to move, thereby reducing the adjustment accuracy required for the pad 66 and the limiting part 612, and thus reducing the installation difficulty of the feeding device 4.

[0096] like Figure 7 As shown, in one possible embodiment, the main body 62 includes a first main body 621 and a second main body 622. The first main body 621 is connected to the fixing frame 1, and one end of the second main body 622 is connected to the first main body 621, while the other end is connected to the adjusting rod 63. The second main body 622 includes a second bent section 622b and a second bent section 622a, wherein the first bent section 622a extends along the direction from the first thread rolling disc 2 to the second thread rolling disc 3, and the second bent section 622b is perpendicular to the first bent section 622a, making the second main body 622 L-shaped.

[0097] The first main body 621 is arranged parallel to the fixed frame 1, which increases the contact area between the first main body 621 and the fixed frame 1. This allows the first main body 621 to be provided with multiple connecting structures for connecting to the fixed frame 1, thereby improving the reliability of the linkage 6 after it is installed on the fixed frame 1. The feeding device 4 is located between the first thread rolling disc 2 and the second thread rolling disc 3, and has a large gap between it and the side wall of the fixed frame 1 where the linkage 6 is installed. The first bent section 622a, which is connected to the first main body 621, extends towards the feeding device 4, allowing the linkage 6 to connect with the feeding member 42 in the feeding device 4. The second bent section 622b is perpendicular to the first bent section 622a, and is arranged parallel to the connecting block 64. This allows multiple adjusting rods 63, each fitted with a second elastic member 631, to be provided between the connecting block 64 and the main body 62, thereby improving the stability of the connection between the connecting block 64 and the main body 62.

[0098] like Figure 7 As shown, in one possible embodiment, a reinforcing plate 65 is provided between the first main body 621 and the first bent section 622a. The first main body 621 and the first bent section 622a are arranged perpendicularly, and the first reinforcing plate 65 can improve the reliability of the connection between the first main body 621 and the first bent section 622a.

[0099] The working process of the thread rolling equipment is as follows: After the first thread rolling disc 2 and the second thread rolling disc 3 process threads on the surface of the previous material, the second thread rolling disc 3 moves away from the first thread rolling disc 2, causing the processed material to fall into the discharge disc 7. The receiving component 41 moves with the second thread rolling disc 3, causing the receiving component 41 to move relative to the feeding component 42. The unprocessed material in the first receiving groove 421 of the feeding component 42 falls into the second receiving groove 411 of the receiving component 41. After the second thread rolling disc 3 stops moving, the second cylinder 472 drives the second push rod 471 to move towards the base 44 and align it with the discharge port. The first cylinder 462 drives the first push rod 461 to extend into the second receiving groove. 411, and clamp the material between the first push rod 461 and the second push rod 471. The first push rod 461 and the second push rod 471 transfer the material between the first thread rolling disc 2 and the second thread rolling disc 3. Then the second thread rolling disc 3 moves towards the first thread rolling disc 2, so that the first thread rolling disc 2 and the second thread rolling disc 3 can clamp the material. When the second thread rolling disc 3 moves towards the first thread rolling disc 2, the receiving part 41 moves with the second thread rolling disc 3, so that the receiving part 41 moves relative to the feeding part 42. After the second thread rolling disc 3 stops moving, the first receiving groove 421 in the feeding part 42 aligns with the feed hole, and the unprocessed material enters the first receiving groove 421 through the feed hole.
