Description

Technical Field

[0001] The present application relates to the technical field of steel wire straightening, and in particular to a steel wire pretreatment and straightening device for spring production. Background Art

[0002] In spring production, wire pretreatment and straightening is a critical step. If the wire is bent, twisted or in an irregular shape, the spring produced will be inaccurate in size, irregular in shape and unstable in mechanical properties. For example, a spring made from bent wire may have an uneven spiral, which will affect the elasticity and service life of the spring.

[0003] In the prior art, pressure is used to straighten steel wire or other similar materials. During the straightening process, a certain pressure is applied to the material to be straightened by straightening rollers, and the straightening operation of the material is achieved through the axial displacement of the material to be straightened. During this process, the straightening rollers need to continuously roll in contact with the material to be straightened, and a continuous friction effect is formed between the straightening rollers and the material to be straightened, which will cause the straightening rollers to generate heat due to friction. At the same time, the faster the straightening speed, the more heat is generated on the straightening rollers. During the continuous straightening process, heat will accumulate at the contact position between the straightening rollers and the material to be straightened, and the accumulated heat will cause the surface temperature of the material to be straightened (steel wire) to increase, affecting the mechanical properties of the material to be straightened. At the same time, the accumulated heat will also accelerate the oxidation rate of the surface of the material to be straightened, reducing the quality of the material to be straightened. In addition, the accumulated heat will also affect the service life of the straightening rollers.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0020] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1, as Figure 1-Figure 14 As shown, a spring production wire pretreatment and straightening device according to an embodiment of the present application includes a frame 1, on which a feeding end 2, a straightening mechanism 3 and a cutting end 4 are sequentially arranged along a straight direction. The material to be straightened enters from the feeding end 2 in sequence, passes through the straightening mechanism 3 for straightening, and is then cut off via the cutting end 4. The feeding end 2 is provided with a conveying power mechanism 201 for providing axial displacement power for the material to be straightened, and the straightening mechanism 3 is provided with a rotating power mechanism 301 for rotating itself to perform pressure straightening action on the material to be straightened.

[0022] It should be noted that in the specific embodiments of the present application, the feeding end 2, the conveying power mechanism 201, the rotating power mechanism 301 and the cutting end 4 are prior arts. For details, reference may be made to paragraphs 0021-0034 of the specification of the patent "A Spring Steel Wire Straightening Machine" with publication number CN219881154U. In the present application, the feeding end 2 and the conveying power mechanism 201 are only used to provide axial displacement capabilities for the material (steel wire) to be straightened, the rotating power mechanism 301 is only used as a power source for rotating the straightening mechanism 3, and the cutting end 4 is only used to cut the straightened material. Its specific structure is not specifically limited here.

[0023] Specifically, Figure 3 and Figure 4 As shown, the straightening mechanism 3 includes a mounting frame 31, two shaft cylinders 32 and two liquid inlet and outlet rotary joints 33, the two shaft cylinders 32 are coaxially connected to the two ends of the mounting frame 31, and the two liquid inlet and outlet rotary joints 33 are symmetrically sleeved on the two shaft cylinders 32, wherein the mounting frame 31 is symmetrically threaded with a plurality of calibration screws 311. It should be noted that the shape of the mounting frame 31 is adjusted by tightening or loosening the nuts at both ends of the calibration screws 311 to avoid deformation of the mounting frame 31 due to force, and to avoid deviation, swinging, jumping, etc. of the axis of the mounting frame 31 during rotation, which may cause failure of the straightening work.

[0024] Two rows of straightening components 5 are arranged in the installation frame 31, and the two rows of straightening components 5 are arranged alternately, such as Figure 3 and Figure 4As shown, it can be understood that the material to be straightened passes between the two rows of straightening components 5, the four straightening components 5 at both ends abut against the material to be straightened, and the four in the middle abut against the material to be straightened, and abut this section of the material to be straightened into a slight S shape. In this way, after the material to be straightened passes through the two rows of straightening components 5, the bends thereon will be straightened by pressure. The specific working principle is obvious to relevant technicians in the field and will not be repeated here.

[0025] The two rows of straightening components 5 are connected to the two liquid inlet and outlet rotary joints 33. It should be noted that in the specific embodiment of the present application, the two rows of straightening components 5 can be connected in series through a hose, or can be connected in parallel with the liquid inlet and outlet rotary joints 33 through a hose.

[0026] The shaft cylinder 32 is rotatably mounted on the bearing seat 321, and the bearing seat 321 is fixed to the frame 1. It should be noted here that the axis of the shaft cylinder 32 is hollow in design to facilitate the passage of the material to be straightened, thereby guiding the material to be straightened and fixing the axis.

[0027] In the specific embodiment of the present application, the two liquid inlet and outlet rotary joints 33 have the same structure and size. Specifically, the liquid inlet and outlet rotary joints 33 include a fixed cylinder 331 rotatably sleeved on the shaft cylinder 32, one end of the fixed cylinder 331 is sealed and rotatably connected to a rotating cylinder 332, the rotating cylinder 332 is fixed to the mounting frame 31, the side wall of the fixed cylinder 331 is connected to an injection nozzle 333, the end of the rotating cylinder 332 is connected to a liquid outlet nozzle 334, the liquid outlet nozzle 334 penetrates the mounting frame 31 and is connected to the straightening component 5. It can be understood that the rotating cylinder 332 rotates with the installation frame 31, and the fixed cylinder 331 is connected to an external cooling medium input device through the injection nozzle 333. It should be noted here that the fixed cylinder 331 can be fixedly connected to the outer ring of the bearing seat 321 through the existing technology, that is, the fixed cylinder 331 remains stationary, and the rotating cylinder 32, the rotating cylinder 332 and the installation frame 31 rotate. In addition, because the two liquid inlet and outlet rotary joints 33 are symmetrically arranged, the injection nozzle 333 on the liquid inlet and outlet rotary joint 33 at the other end is the liquid output end, and the liquid outlet nozzle 334 is the liquid input end.

[0028] like Figure 5-Figure 8 As shown, the straightening assembly 5 includes a straightening wheel 54 rotatably mounted on a mounting seat 52, the mounting seat 52 is lifted and lowered and connected to the mounting frame 31, a channel for liquid circulation is arranged in the straightening wheel 54, the liquid channel is arranged along the axial direction of the straightening wheel 54, the two ends of the liquid channel are symmetrically arranged, and a plurality of V-shaped branch channels are circumferentially evenly connected between the two ends of the liquid channel.

[0029] Specifically, an adjusting screw 51 is fixedly connected to the mounting seat 52, and the adjusting screw 51 slides through the mounting frame 31. The adjusting screw 51 is threadedly connected to nuts at the inner and outer sides of the mounting frame 31. It can be seen that the adjusting screw 51 can be axially displaced relative to the mounting frame 31 by twisting the two nuts, even if the straightening wheel 54 is raised or lowered to achieve abutment or tightening of materials to be straightened of different thicknesses. Two infusion nozzles 521 are symmetrically connected on the mounting seat 52, and the two infusion nozzles 521 are respectively connected to the two liquid inlet and outlet rotary joints 33, and the connection can be achieved through a hose.

[0030] Furthermore, a bearing shaft 53 is fixedly connected to the mounting seat 52, and an L-shaped liquid inlet channel 531 and a liquid outlet channel 532 are respectively arranged in the bearing shaft 53, and the inlet end of the liquid inlet channel 531 and the outlet end of the liquid outlet channel 532 are respectively connected to the two infusion nozzles 521, and the outlet end of the liquid inlet channel 531 and the inlet end of the liquid outlet channel 532 are respectively arranged on the side wall of the bearing shaft 53, such as Figure 8 As shown, the two L-shaped liquid inlet channels 531 and the liquid outlet channels 532 extend to a section of the side wall of the load-bearing shaft 53 and are preferably arranged in reverse. This can enhance the strength of the load-bearing shaft 53 while avoiding the instability of the center of gravity of the load-bearing shaft 53. A convex ring 533 is arranged in the center of the side wall of the load-bearing shaft 53, and grooves 534 are symmetrically arranged at both ends of the side wall of the load-bearing shaft 53. A sealing ring 535 is sealed and embedded in the groove 534 to ensure the sealing between the load-bearing shaft 53 and the straightening wheel 54.

[0031] Furthermore, a concave portion 541 is circumferentially provided on the side wall of the straightening wheel 54, and the cross section of the concave portion 541 is V-shaped, which is convenient for clamping the material to be straightened and for performing straightening operations on the material to be straightened.

[0032] A blocking ring 542 is disposed at the center of the inner side of the straightening wheel 54, and the blocking ring 542 is sealingly and slidably connected to the convex ring 533. Figure 7 and Figure 8As shown, the blocking ring 542 and the convex ring 533 can divide the chamber formed between the straightening wheel 54 and the bearing shaft 53 into two independent chambers, and forcibly drain and guide the liquid. The channels for liquid circulation arranged in the straightening wheel 54 are the end portion liquid chamber 543 and the axial channel 544, wherein the end portion liquid chamber 543 is symmetrically arranged in the straightening wheel 54. It should be noted here that the end portion liquid chamber 543 can temporarily store and divert the cooling medium, and the axial channel 544 is a V-shaped branch channel, and multiple axial channels 544 are evenly connected to the two end portion liquid chambers 543 in the circumferential direction. It should be noted that the multiple axial channels 544 are distributed on the outer side of the end portion liquid chamber 543, and the V-shape of the axial channel 544 is adapted to the V-shape of the concave portion 541. Two groups of first radial through holes 545 are symmetrically arranged on the inner side of 54, and the two groups of first radial through holes 545 are connected to the two end portion liquid cavities 543 respectively. The first radial through holes 545 are circumferentially evenly connected to the end portion liquid cavities 543. It should be noted here that after the cooling medium enters one of the end portion liquid cavities 543 from the inlet end, the straightening wheel 54 rotates under the axial displacement of the material to be corrected, so the cooling medium will surge into the multiple axial channels 544 under the centrifugal force and enter the end portion liquid cavity 543 at the other end. The V-shaped multiple axial channels 544 are evenly distributed circumferentially and matched with the V-shape of the concave portion 541, so the accumulated heat generated on the straightening wheel 54 will be cooled and taken away, thereby reducing the accumulated heat on the straightening wheel 54.

[0033] Two groups of positioning holes 546 are symmetrically arranged at both ends of the straightening wheel 54. The positioning holes 546 are evenly arranged axially to facilitate the fixation and positioning of other components.

[0034] In a specific embodiment of the present application, two rotating parts 55 of the same structure and size are symmetrically arranged at both ends of the load-bearing shaft 53. The rotating part 55 is sealed and rotatably sleeved on the load-bearing shaft 53, and the rotating part 55 is sealed and fixedly inserted into the straightening wheel 54. It can be seen that the straightening wheel 54 and the rotating part 55 are fixed, and the rotating part 55 and the load-bearing shaft 53 are sealed and rotatably connected.

[0035] Among them, the rotating member 55 includes a protrusion 551 and a cylinder 552, the protrusion 551 extends out of the end of the straightening wheel 54, and the cylinder 552 is sealed and inserted in the straightening wheel 54. The inner side of the protrusion 551 is provided with a sealing groove 556 compatible with the sealing ring 535, and the end of the protrusion 551 is evenly fixed with a plurality of positioning bolts 555 that are plugged in one-to-one with the positioning holes 546. The cylinder 552 is hollow with one end open, and the open end of the cylinder 552 does not cover the outlet end of the liquid inlet channel 531 and the inlet end of the liquid outlet channel 532. It can be seen that through the one-to-one corresponding plug-in relationship between the positioning bolts 555 and the positioning holes 546, the rotating member 55 is positioned and inserted in the straightening wheel 54, and the cylinder 552 does not cover the outlet end of the liquid inlet channel 531 and the inlet end of the liquid outlet channel 532, so that a chamber for liquid steering is formed between the straightening wheel 54 and the load-bearing shaft 53.

[0036] Among them, a drainage cavity 553 is axially arranged in the cylinder 552, and the drainage cavity 553 is open at one end away from the protrusion 551, and a plurality of second radial through holes 554 are evenly arranged circumferentially at one end of the drainage cavity 553 toward the protrusion 551. The plurality of second radial through holes 554 correspond to and are connected with the plurality of first radial through holes 545. It can be seen that the cooling medium enters through the liquid inlet and outlet rotary joint 33 at one end, passes through an infusion nozzle 521 on the mounting seat 52, and enters the liquid inlet channel 531, and then the cooling medium passes through the liquid diversion cavity between the straightening wheel 54 and the bearing shaft 53. The liquid enters the drainage chamber 553 on this side through the second radial through hole 554 and the corresponding first radial through hole 545 on this side, enters the end portion liquid chamber 543 at this end, passes through a plurality of V-shaped axial channels 544, and then enters the end portion liquid chamber 543 on the other end through the corresponding first radial through hole 545 and the second radial through hole 554, and then enters the drainage chamber 553 on the other side through the liquid diverting chamber on this side into the liquid outlet channel 532, and then flows out of the straightening assembly 5 from another infusion nozzle 521, and the accumulated heat on the straightening wheel 54 is taken away by the flow of cooling medium.

[0037] In the related art, in a spring production wire pretreatment and straightening device, a straightening wheel 54 is rotatably connected to a bearing shaft 53 through a rotating member 55. After long-term use, wear is inevitable between the rotating member 55 and the bearing shaft 53. The debris generated by the wear, if accumulated on the inner side of the straightening wheel 54, will aggravate the wear between the rotating member 55 and the bearing shaft 53. Moreover, the contact area between the cylinder 552 of the rotating member 55 and the bearing shaft 53 is relatively large, and a certain amount of heat will be generated during the rotation. Although the cooling medium will take away part of the heat when flowing into the drainage cavity 553, the full coverage contact will inevitably aggravate the generation of heat, and the accumulation of heat will aggravate the wear between the rotating member 55 and the bearing shaft 53.

[0038] Embodiment 2, according to some embodiments of the present application, such as Figure 5 , Fig. 9 and Fig.10 As shown, a flow guide component 6 is axially arranged in the cylinder 552 , and the flow guide component 6 includes a spiral groove 61 and a spiral sheet 62 . The spiral groove 61 is arranged on one side of the cylinder 552 that is attached to the bearing shaft 53 , and the spiral sheet 62 is arranged in the drainage cavity 553 .

[0039] Among them, the spiral groove 61 extends the drainage cavity 553 to the side wall of the bearing shaft 53, so that the cylinder 552 and the bearing shaft 53 will not be fully covered, reducing the contact surface between the two. At the same time, the cooling medium can also contact the side wall of the bearing shaft 53 through the spiral groove 61.

[0040] The spiral grooves 61 and the spiral sheets 62 are arranged alternately, the spiral sheets 62 are fixed to the cavity wall of the drainage cavity 553, and the spiral directions and pitches of the spiral grooves 61 and the spiral sheets 62 are the same.

[0041] Therefore, when the cooling medium flows in the drainage chamber 553, first, the circulation space of the cooling medium is reduced due to the influence of the spiral blade 62, which will increase the flow rate of the cooling medium. At the same time, the spiral design of the spiral blade 62 will guide the cooling medium here and extend its flow path in the drainage chamber 553. In this way, the cooling medium will better carry the accumulated heat in the rotating part 55, and the design of the spiral groove 61 will further increase the flow path of the cooling medium in the drainage chamber 553. At the same time, the volume of the spiral groove 61 is significantly smaller than the volume of the drainage chamber 553, so the flow rate of the cooling medium therein will be faster. The cooling medium can better carry away the heat generated between the rotating part 55 and the bearing shaft 53 through the spiral groove 61. At the same time, the spiral groove 61 reduces the The contact area between the carrier shafts 53 further reduces the friction between the rotating member 55 and the carrier shaft 53, and the increase in the flow velocity in the entire drainage cavity 553 and the fixed flow direction can allow the cooling medium to carry away the debris generated by wear during the flow, and finally be discharged from the infusion nozzle 521 at the output end of the mounting seat 52 along the flow path. It should be noted in the specific embodiment of the present application that at this time, the plurality of straightening components 5 and the two liquid inlet and outlet rotary joints 33 are preferably connected in parallel, so as to avoid the wear debris in the previous straightening component 5 formed in series being carried by the liquid flow to the next straightening component 5, so as to prevent excessive debris from accumulating inside the straightening component 5 at the rear end of the flow direction, thereby affecting the circulation of the cooling medium and even affecting the normal rotation of the straightening wheel 54 on the carrier shaft 53.

[0042] In the related art, a spring production wire pretreatment and straightening device uses liquid flow to carry out the wear debris formed between the rotating part 55 and the load-bearing shaft 53 during the circulation process, which can reduce the wear between the rotating part 55 and the load-bearing shaft 53 and extend the service life of both. However, in the circulation path within the straightening component 5, the cooling medium needs to enter the drainage chamber 553 from the end portion liquid chamber 543 before flowing out of the straightening component 5. During this process, debris is easily accumulated at the entrance of the drainage chamber 553, the inside of the straightening wheel 54 and the liquid diverting chamber formed between the load-bearing shaft 53. If the debris is not processed, the debris will affect the normal use of the load-bearing shaft 53 and the rotating part 55.

[0043] Embodiment 3, according to some embodiments of the present application, such as Figure 5 , Figure 6 , Figure 11-Figure 14 As shown, the end of the straightening wheel 54 (liquid outlet end) toward which the liquid flows out is coaxially connected with the impurity removal component 7, and the impurity removal component 7 includes an impurity removal chamber 71 coaxially connected to the straightening wheel 54, and a blocking ring 72 is coaxially fixed to the end of the impurity removal chamber 71, and the blocking ring 72 is sealingly and slidably inserted in the end portion of the liquid cavity 543, and a filter ring 73 is coaxially arranged inside the impurity removal chamber 71, and an axial liquid inlet channel 74 connected to the impurity removal chamber 71 is arranged at the end of the straightening wheel 54.

[0044] Among them, a debris removal chamber 711 is arranged in the debris removal chamber 71, and a plurality of liquid inlet axial holes 712 and a coaxial liquid outlet annular groove 713 are evenly arranged circumferentially at one end of the debris removal chamber 71 facing the straightening wheel 54. The plurality of liquid inlet axial holes 712 are located on the outer side of the blocking ring 72, and the liquid outlet annular groove 713 is located on the inner side of the blocking ring 72, so that the liquid inlet and outlet on the debris removal chamber 71 are separated to facilitate the circulation of the cooling medium, and the filter ring 73 is located between the plurality of liquid inlet axial holes 712 and the liquid outlet annular groove 713; a sewage discharge nozzle 714 is arranged on the side wall of the debris removal chamber 71, and the sewage discharge nozzle 714 is connected with the debris removal chamber 711, so that the debris in the debris removal chamber 711 can be easily drawn out through the sewage discharge nozzle 714.

[0045] It should be noted that the filter ring 73 is preferably detachably installed inside the impurity removal chamber 711 to facilitate the subsequent anti-blocking treatment of the filter ring 73. Specifically, the end of the impurity removal chamber 71 away from the straightening wheel 54 can be set to a structure with a sealing cover to facilitate the removal of the filter ring 73 from the impurity removal chamber 711.

[0046] Specifically, the end seal of the blocking ring 72 abuts against the end of the end liquid cavity 543 away from the impurity removal compartment 71; sealing rings 721 are coaxially arranged on the inner and outer sides of the blocking ring 72. It can be understood that after the impurity removal compartment 71 is installed on the straightening wheel 54, the end liquid cavity 543 on the liquid outlet side of the straightening wheel 54 is intercepted by the blocking ring 72 to form a blocking effect. At this time, the cooling medium can and can only enter the impurity removal compartment 71 from the axial liquid inlet channel 74.

[0047] Furthermore, the axial liquid inlet channel 74 includes an inclined channel 741, an axial liquid outlet channel 742 and a limiting groove 743. The inclined channel 741 is evenly arranged at the end of the straightening wheel 54 in the circumferential direction. The inclined channel 741 is connected to the connection between the end portion liquid cavity 543 and the axial channel 544. The inclined channel 741 is radially expanded and inclined along the axial direction from the end portion liquid cavity 543 to the impurity removal compartment 71. The inclined channel 741 and the liquid inlet axial hole 712 correspond to each other and are connected. Therefore, the liquid flow of the cooling medium will enter the impurity removal cavity 711 from the inclined channel 741, and the rotating straightening wheel 54 can use centrifugal force to avoid the accumulation of debris in the end portion liquid cavity 543 of the liquid outlet end (the debris will follow the liquid flow into the inclined channel 741 under the action of centrifugal force and finally enter the impurity removal cavity 711).

[0048] The axial liquid outlet channel 742 is evenly arranged at the end of the straightening wheel 54 in the circumferential direction, and the axial liquid outlet channel 742 is respectively connected to the end liquid cavity 543 and the liquid outlet annular groove 713, and the limiting groove 743 is arranged between the inclined channel 741 and the axial liquid outlet channel 742. The limiting groove 743 is connected to the end liquid cavity 543, and the blocking ring 72 is sealingly inserted in the limiting groove 743. Two annular grooves that are sealingly adapted to the sealing ring 721 are coaxially arranged in the limiting groove 743, which form a sealed connection between the impurity removal compartment 71 and the straightening wheel 54 and a certain positioning function for the impurity removal compartment 71.

[0049] It can be understood that the blocking ring 72 is sealed and inserted into the limit groove 743 and abuts against the end portion liquid chamber 543, so that the end portion liquid chamber 543 is divided, and the liquid flow of the cooling medium flows from the end portion liquid chamber 543 located on the outside of the blocking ring 72 to the impurity removal chamber 711. After being filtered by the filter ring 73, the liquid flow of the cooling medium flows from the end portion liquid chamber 543 located on the inside of the blocking ring 72 to the drainage chamber 553 on the side of the liquid output end. In this way, it is possible to avoid the accumulation of debris at the entrance of the drainage chamber 553 on the side of the liquid outlet end, the liquid turning chamber formed between the inside of the straightening wheel 54 and the load-bearing shaft 53.

[0050] In actual use, the cooling medium flow carries debris from the liquid flow inlet end of the straightening wheel 54 through multiple axial channels 544 to the end portion liquid cavity 543 in the liquid outlet direction. Since the blocking ring 72 is sealed and inserted into the limiting groove 743 and abuts against the end portion liquid cavity 543 on this side, the end portion liquid cavity 543 on this side is divided. The cooling medium flow can and can only flow from multiple inclined channels 741 connected at the hinge of the end portion liquid cavity 543 and the axial channel 544 to the impurity removal cavity 711. After being filtered by the filter ring 73 in the impurity removal cavity 711, the cooling medium carries debris and enters the end portion liquid cavity 543 located on the inner side of the blocking ring 72 through the axial liquid outlet channel 742, and finally flows out from the inlet of the liquid output end. The flow cavity 553 flows toward the infusion nozzle 521 at this end and flows out of the straightening wheel 54, and the debris intercepted by the filter ring 73 will be temporarily stored in the cavity of the impurity removal cavity 711 located outside the filter ring 73, and after the equipment is shut down, the temporarily stored debris can be discharged through the sewage discharge nozzle 714, and the debris in the impurity removal cavity 711 can also be cleared when the filter ring 73 is removed. It can be understood that the design of the inlet and outlet of the liquid on the impurity removal cavity 711 (the inlet is on the outside of the filter ring 73, and the outlet is on the inside of the filter ring 73) can use the centrifugal force generated during the rotation of the straightening wheel 54 to further improve the filtering effect of the cooling medium when passing through the filter ring 73 (the centrifugal force causes the debris to move radially outward, and the liquid flow to move radially inward, further improving the separation effect of the two).

[0051] It should be noted that the specific models and specifications of the feeding end 2, the conveying power mechanism 201, the rotating power mechanism 301, the calibration screw 311, the bearing seat 321, the cutting end 4, the adjusting screw 51 and the sealing ring 535 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0052] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
