Description

Technical Field

[0001] This invention relates to the field of metal processing, specifically to a rapid spheroidization treatment device and preparation process for high-strength bolt processing. Background Technology

[0002] Spheroidizing annealing is an annealing process that spheroidizes carbides in steel, resulting in a microstructure with spherical or granular carbides uniformly distributed in a ferrite matrix. Spheroidizing annealing is mainly used for eutectoid and hypereutectoid steels to obtain a spheroidized microstructure similar to granular pearlite (called spheroidized microstructure because it is not necessarily a eutectoid composition), thereby reducing hardness, improving machinability, and preparing the microstructure for quenching.

[0003] Spheroidized structures not only have better plasticity and toughness than lamellar structures, but also have slightly lower hardness. When machining workpieces with spheroidized structures, the cutting tool can avoid cutting through hard and brittle cementite and instead pass through soft ferrite, thus extending the tool life and improving the machinability of the steel.

[0004] In the process, the steel is heated to 20-30 degrees above Ac1 and then enters the heat preservation process, which generally lasts for 2-4 hours. It needs to be isothermally heated to about 20 degrees below Ar1, so an isothermal device is required. A wire rod spheroidizing annealing process is disclosed in this regard, with the announcement number: CN114622065B. This device improves the problems that may occur in the spheroidizing process to a certain extent, but it does not improve the isothermal process. Existing isothermal equipment usually enters the isothermal environment by conveying, which occupies a relatively large area and has a relatively low degree of automation. Since the steel is just heated to a certain temperature, which is a high temperature that is unacceptable to the human body, the transportation process is prone to accidents. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid spheroidizing treatment device and preparation process based on high-strength bolt processing, so as to solve the above-mentioned problems of low automation and easy accidents.

A positioning plate is fixed on the opposite side of the two transmission plates, and the positioning plate passes through the box body and is slidably connected to the box body.

[0016] A bidirectional lead screw is rotatably mounted on the housing. Two threaded sleeves are fitted onto the bidirectional lead screw and are threadedly engaged with it. The two threaded sleeves are fixed to the transmission plate. A transmission shaft is also rotatably mounted on the housing. The transmission shaft is connected to the bidirectional lead screw through a gear set. Both ends of the plurality of main shafts are provided with first positioning holes that cooperate with the positioning plate.

[0017] The first plate is provided with a second rack, which engages with a third gear rotatably mounted on the outer wall of the housing. The shaft of the third gear is connected to the drive shaft via a fifth transmission chain.

[0020] A transmission rod is rotatably mounted on the housing. The transmission rod is connected to two conveyor wheel sets through a third transmission chain and a first transmission chain. The transmission rod is also connected to the ratchet shaft through a fourth transmission chain.

[0029] A rapid spheroidization preparation process based on high-strength bolt processing is implemented using the aforementioned rapid spheroidization equipment based on high-strength bolt processing, and includes the following steps:

[0030] Step 1: Stack the treated bolts and material plates in the material rack, then place the material rack on the feeding section and push the material rack toward the box using the pushing device;

[0031] Step 2: During movement, the sealing plate is first lifted to open the slot. After the material rack moves into the box, the material rack and the connecting part are connected by the snap-fit ​​structure.

[0032] Step 3: Drive the flow component to work, so that the material rack moves along the conveying direction of the flow component, and at the same time drive the sealing plate to descend and close the slot.

[0033] Repeating steps one and two will store another rack inside the box.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] Effect 1: This application uses a flow component to store the material rack, so that the temperature inside the box reaches the required isothermal temperature. The flow structure can greatly reduce the space occupied.

[0036] Effect 2: The connection between the structural component rack and the connecting part is automatic, thereby reducing the possibility of accidents.

[0037] Effect 3: Because the material plates inside the rack are stacked, compared to the irregular arrangement of the material boxes in existing technologies, more bolts can be stored at the same time;

[0038] Fourthly, this application has a relatively high degree of automation. Except for placing the material rack on the feeding section and removing the material rack from the flow structure, everything else is done by this equipment, making it relatively practical. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0052] Example 1, please refer to Figures 1 to 10 A rapid spheroidizing processing equipment based on high-strength bolt processing includes a housing 1, a flow component installed inside the housing 1, and guide rails 16 integrally formed on both sides of the housing 1. A U-shaped support plate 2 is slidably installed on the guide rails 16.

[0053] Among them, the support plate 2 includes a first plate and a second plate. The ends of the first plate and the second plate are fixedly connected by a third plate. The first plate, the second plate and the third plate form a U-shaped plate. The third plate is provided with a feeding part 4 on the side facing the box 1.

[0054] A drive assembly is installed on one side of the housing 1, and the drive assembly is connected to the No. 1 plate and the flow assembly respectively.

[0055] A material rack 3 is placed on the feeding section 4. Multiple material plates 34 are stacked inside the material rack 3. The material rack 3 is detachably connected to the flow component through a snap-fit ​​component.

[0056] In this embodiment of the invention, the bolts are supported by the material plate 34. The material plate 34 is stacked in the material rack 3 in sequence. Then the material rack 3 is placed on the feeding part 4. Then, the material rack 3 and the support plate 2 are pushed towards the box 1 by the pushing device, so that the material rack 3 is driven to follow the movement by the feeding part 4, so that the material rack 3 is pushed into the box 1. The material rack 3 is connected to the flow component by the locking component. When the support plate 2 and the material rack 3 move back and forth, the flow component moves so that the material rack 3 is disengaged from the feeding part 4.

[0057] Among them, when the support plate 2 moves back and forth, the flow group is driven by the drive component to work;

[0058] It should be noted that the box body 1 has a slot on the side facing the material rack 3 for the material rack 3 and the feeding part 4 to pass through;

[0059] It should also be noted that the pushing device in this embodiment is a cylinder, which is not shown in the diagram. Of course, an electric telescopic rod or the like can also be used, and this application does not impose any specific limitations.

[0060] Example 2: The difference from Example 1 is that the flow component includes two sets of conveyor wheels rotatably installed inside the housing 1. The two sets of conveyor wheels are symmetrically arranged and located on both sides inside the housing 1.

[0061] Each set of conveyor wheels includes four conveyor wheels, which are arranged in a rectangle and rotatably connected to the housing 1; the rectangular arrangement is such that the conveyor wheels are located at the four corners of the rectangle;

[0062] The four conveyor wheels are connected by a conveyor chain 25. Multiple main shafts 29 are equidistantly arranged on the conveyor chain 25 along the conveying path. The multiple main shafts 29 are rotatably connected to the conveyor chain 25. A connecting part 26 is fixedly installed on the main shaft 29. The connecting part 26 is detachably connected to the material rack 3 through the engaging assembly. One of the conveyor wheels in the two sets of conveyor wheels is connected to the drive assembly.

[0063] In this embodiment of the invention, when the drive component is working, it drives two sets of conveyor wheel sets to rotate simultaneously, thereby conveying the conveyor chain 25. When the conveyor chain 25 is conveying, it drives the main shaft 29 to move along the conveying path of the conveyor chain 25.

[0064] Among them, the connecting part 26 has a lower center of gravity. When the conveyor chain 25 is conveying, the connecting part 26 is driven to move by the main shaft 29. Due to the center of gravity, the connecting part 26 always maintains its shape and does not rotate. Simply put, the bottom of the connecting part 26 always faces the bottom of the box 1.

[0065] Both sides of the housing 1 are provided with transmission plates 9. The two transmission plates 9 are slidably installed on the housing 1 through the first guide rod 11 fixed on the housing 1. The two transmission plates 9 are fixed with positioning plates 10 on opposite sides. The positioning plates 10 pass through the housing 1 and are slidably connected to the housing 1.

[0066] A bidirectional lead screw 5 is rotatably mounted on the housing 1. Two threaded sleeves 30 are fitted onto the bidirectional lead screw 5 and threadedly engaged with it. The two threaded sleeves 30 are fixed to the transmission plate 9. A transmission shaft 31 is also rotatably mounted on the housing 1. The transmission shaft 31 is connected to the bidirectional lead screw 5 through a gear set 32. Both ends of the plurality of main shafts 29 are provided with first positioning holes 33 that cooperate with the positioning plate 10.

[0067] The first plate is provided with a second rack portion 23, which cooperates with a third gear 21 rotatably mounted on the outer wall of the housing 1. The shaft of the third gear 21 is connected to the transmission shaft 31 through a fifth transmission chain 22.

[0068] In this embodiment of the invention, when the support plate 2 moves toward the housing 1, the third gear 21 is driven to rotate by the meshing of the second rack portion 23 and the third gear 21. When the third gear 21 rotates, the transmission shaft 31 is driven to rotate by the fifth transmission chain 22. The transmission shaft 31 drives the transmission rod 6 to rotate by the gear set 32. When the transmission rod 6 rotates, the two threaded sleeves 30 are driven to move relative to each other by the threaded engagement with the two threaded sleeves 30.

[0069] When the two threaded sleeves 30 move relative to each other, the transmission plate 9 drives the two positioning plates 10 to move relative to each other, thereby inserting the positioning plate 10 into the first positioning hole 33 to limit the main shaft 29, so that the main shaft 29 cannot rotate when the positioning plate 10 is inserted into the first positioning hole 33, so as to ensure that the main shaft 29 will not rotate when the material rack 3 moves into the box 1 and connects with the flow component, thus preventing the connection from failing.

[0070] Similarly, when the support plate 2 moves back and forth, the meshing of the second rack 23 and the third gear 21 drives the transmission rod 6 to rotate in the opposite direction, thereby driving the two threaded sleeves 30 to move in opposite directions, so as to pull the positioning plate 10 out of the first positioning hole 33 and make the main shaft 29 resume rotation.

[0071] It should be noted that the gear set 32 ​​in this embodiment includes two meshing gears. The transmission ratio between the two gears is not limited in this application. The two gears are fixed to the transmission shaft 31 and coaxially, respectively. Of course, they can be replaced by a transmission belt and a belt roller.

[0072] The first positioning hole 33 is not circular, and the positioning plate 10 has an inclined surface at the end facing the first positioning hole 33.

[0073] In this embodiment of the invention, the first positioning hole 33 is set as a rounded rectangle, but it can also be set as a triangle, rectangle, polygon, etc.

[0074] The inclined surface of the positioning plate 10 means that all four corners are chamfered to facilitate insertion into the first positioning hole 33.

[0075] The drive assembly includes a ratchet 19 rotatably mounted on one side of the housing 1, and the ratchet 19 is disposed on the pawl portion 20 of the first plate for one-way engagement;

[0076] A transmission rod 6 is rotatably mounted on the housing 1. The transmission rod 6 is connected to two conveyor wheel sets through a third transmission chain 17 and a first transmission chain 8. The transmission rod 6 is also connected to the shaft of the ratchet 19 through a fourth transmission chain 18. The third transmission chain 17 is connected to one of the conveyor wheels in the conveyor wheel set.

[0077] In this embodiment of the invention, when the support plate 2 moves toward the box 1, it drives the pawl part 20 to move accordingly. When the pawl part 20 moves to the position of the ratchet 19, the ratchet 19 and the pawl part 20 do not have a transmission relationship. When the support plate 2 moves back and forth, the pawl part 20 drives the ratchet 19 to rotate. The ratchet 19 drives the transmission rod 6 to rotate through the fourth transmission chain 18. Thus, the transmission rod 6 drives the two conveying wheel sets to rotate synchronously through the third transmission chain 17, so that the flow component does not work when the support plate 2 moves toward the box 1, but works when moving back and forth.

[0078] The pawl portion 20 includes a groove, in which a pawl is joined, and a torsion spring is installed at the joint of the pawl.

[0079] The box 1 has a slot on the side facing the material rack 3 for the material rack 3 and the feeding part 4 to pass through. A sealing plate 24 is slidably installed on the box 1 at the slot. A rack plate 39 is fixed on the sealing plate 24. The rack plate 39 meshes with a second gear 15 rotatably installed on the box 1.

[0080] The second plate is provided with a first rack portion 13, which cooperates with a first gear 12 rotatably mounted on the housing 1. The shaft of the first gear 12 is connected to the shaft of the second gear 15 through a second transmission chain 14.

[0081] The box 1 is also provided with a limiting strip on the side facing the material rack 3; the limiting strip is used to limit the travel of the sealing plate 24, so that when the power of the first gear 12 is lost, the sealing plate 24 can be supported by the limiting strip due to its own weight as it falls.

[0082] In this embodiment of the invention, when the support plate 2 moves toward the box 1, the first rack portion 13 on the second plate drives the first gear 12 to rotate. The first gear 12 drives the second gear 15 to rotate through the second transmission chain 14. Since the second gear 15 meshes with the rack plate 39, the second gear 15 rotates and drives the sealing plate 24 to rise vertically through the rack plate 39.

[0083] When the support plate 2 faces the box 1, the material rack 3 is sent into the box 1. During the pushing process, the slot blocked by the sealing plate 24 is opened. During the reciprocating motion, the above motion is repeated in the opposite direction to close the sealing plate 24.

[0084] The feeding section 4 is rectangular in shape, and the side of the feeding section 4 facing the box 1 is open.

[0085] The engaging assembly includes two limiting blocks 40 fixed to the bottom of the connecting part 26, and the two limiting blocks 40 slide in conjunction with the limiting grooves 35 formed on the material rack 3; both limiting blocks 40 are L-shaped.

[0086] A second guide rod 28 is slidably mounted on the connecting part 26. A spherical part 38 is fixed at the end of the second guide rod 28. The spherical part 38 cooperates with the second positioning hole 36 opened on the material rack 3.

[0087] A spring 37 is fitted on the second guide rod 28. One end of the spring 37 is fixed to the second guide rod 28, and the other end is fixed to the spherical part 38.

[0088] In this embodiment of the invention, when the material rack 3 is pushed toward the box 1 by the support plate 2 and the feeding part 4, the limiting block 40 is first inserted into the limiting groove 35, and the connecting part 26 and the material rack 3 are connected by the sliding cooperation between the limiting groove 35 and the limiting block 40.

[0089] When the limiting block 40 is inserted into the limiting groove 35, the second guide rod 28 is driven to rise vertically through the spherical part 38. When the second guide rod 28 rises, the spring 37 is pulled up, so that the spring 37 stores a certain elastic potential energy. This process is called yielding. When the two second positioning holes 36 coincide with the two spherical parts 38, the elastic potential energy of the spring 37 is released to drive the spherical part 38 to move into the second positioning hole 36, limiting the relative movement direction of the material rack 3 and the connecting part 26. At this time, the engaging connection between the connecting part 26 and the material rack 3 is completed.

[0090] The second guide rod 28 has a removal handle 27 fixed to its top.

[0091] In this embodiment of the invention, this embodiment is used for the engagement between the contact connection part 26 and the material rack 3;

[0092] When it is necessary to engage, the removal handle 27 is driven to stand upright by external force. At this time, the removal handle 27 drives the second guide rod 28 to stand up, thereby causing the spherical part 38 to move out of the second positioning hole 36 and make room again. At this time, the material rack 3 can be removed from the connecting part 26 by pulling the material rack 3 with external force.

[0093] When the second guide rod 28 is erected, the elastic potential energy generated by removing the handle 27 disappears when the external force is gone, and the second guide rod 28 and the spherical part 38 are driven to reset by releasing the elastic potential energy.

[0094] The box 1 is also equipped with a temperature control device to control the temperature inside the box 1. The box 1 is also detachably equipped with a door 7 in the direction away from the material rack 3, and the material rack 3 can be unloaded by removing the door 7.

[0095] It should also be noted that the "transmission chain" in this invention is a chain transmission structure, which can be a chain, synchronous belt, belt, etc., while the conveyor chain 25 located in the housing 1 is a chain, and the chain is made of high temperature resistant metal.

[0096] This invention also provides a rapid spheroidization preparation process based on high-strength bolt processing. The rapid spheroidization preparation process based on high-strength bolt processing is implemented using the aforementioned rapid spheroidization treatment equipment based on high-strength bolt processing, and includes the following steps:

[0097] Step 1: Stack the treated bolts and material plates 34 in the material rack 3, then place the material rack 3 on the feeding part 4, and push the material rack 3 toward the box 1 through the pushing device;

[0098] Step 2: During the movement, the sealing plate 24 is first lifted to open the slot. After the material rack 3 moves into the box 1, the material rack 3 and the connecting part 26 are connected by the snap-fit ​​structure.

[0099] Step 3: Drive the flow component to work, so as to drive the material rack 3 to move along the conveying direction of the flow component, and at the same time drive the sealing plate 24 to descend and close the slot.

[0100] Repeating steps one and two will allow another rack 3 to be stored in box 1.

[0101] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0102] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
