Description

Technical Field

[0001] The present application relates to the field of heating devices, and in particular to a metal wire heating device for spring production. Background Art

[0002] In the production of large springs, metal wire is first cut into segments of specific lengths and then heated in a furnace. Once heated, the wire is removed and the spring winding process begins. However, due to the varying lengths of formed springs, the required wire lengths also vary. To meet these varying production requirements, the furnaces are typically designed to be longer. This design leaves some space unused when heating shorter wires. Furthermore, after the wire is formed by winding, the ends must be trimmed and polished, and the formed wire must be reheated for fine-tuning. While there is space available within the furnace for heating the wire, it cannot be effectively utilized for this secondary heating step. In many cases, companies are forced to install additional furnaces specifically for this secondary heating of the wire after winding. This not only increases the cost of the furnace equipment but also prevents the furnace from fully utilizing its internal space, resulting in a waste of both furnace space and heat energy. Summary of the Invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a metal wire heating device for spring production. The device can flexibly realize the combination and splicing of the first furnace body, the second furnace body, the third furnace body and the fourth furnace body, and accurately adjust the space length inside the entire heating furnace, thereby meeting the heating requirements of metal wire segments of different lengths. When it is necessary to heat a short metal wire, the third furnace body can be conveniently moved to the side of the first furnace body and the second furnace body, so that the three can be cleverly combined to construct a dedicated heating furnace for secondary heating. In this way, the metal wire after the spring is wound can be directly placed inside the third furnace body for secondary heating. This innovative design, on the one hand, reduces the investment in additional heating equipment, and on the other hand, greatly improves the utilization rate of the internal space of the heating furnace, avoids the waste of heat energy caused by idle space, and takes into account both economic benefits and efficient use of energy.

[0015] The heating process of metal wire segments is crucial in the production of large springs. Currently, the segments must be moved to the entrance of a heating furnace. Using simple tools, the entire length of wire is then pushed slowly into the depths of the furnace. Once heated, the wire must be removed from the furnace and moved to the spring winding device. This process is characterized by a low degree of automation and results in low production efficiency.

[0016] The lifting mechanism is a lifting mechanism, and the lifting mechanism is a lifting mechanism, and the lifting mechanism is a lifting mechanism, and the lifting mechanism is a lifting mechanism, and a lifting mechanism is connected with the lifting mechanism of the lifting mechanism to the lifting device, and the lifting mechanism is connected with the lifting mechanism of the lifting mechanism to the lifting device.

[0017] When the loading operation begins, a placement rack is first placed steadily on the transfer vehicle, and the segments of metal wire are neatly stacked on the placement rack. Then, another placement rack is laid on top of the placed metal wire, and the segments of metal wire continue to be placed on the placement rack. The operation is cyclically carried out in this way to achieve orderly stacking of the segments of metal wire on the transfer vehicle. Subsequently, the transfer vehicle is moved to one side under the support frame, the equipment is started, and the threaded rod is rotated to start operation. The clutch on one side of the first sliding frame is immediately threadedly connected with the rotating threaded rod, thereby driving the first sliding frame to move and transporting the two clamping and lifting frames to the top of the transfer vehicle. At this time, the clamping and lifting frame not only produces horizontal displacement, but also its bottom performs lifting and lowering movements, accurately inserting the bottom into one side of the placement rack, relying on the coordinated movement of the clamping and lifting frame and the first sliding frame to lift the segments of metal wire on the placement rack steadily and transfer them to the material rack. The material rack is aligned with the middle of the segments of metal wire. After effective support is formed, the lifting end of the clamping lifting frame gradually descends, so that the placement frame and the metal wire are smoothly separated. At this time, the side of the second furnace body close to the support frame is in an open state, and the clutch on the first sliding frame is disconnected from the rotating threaded rod, while the clutch on the second sliding frame maintains threaded connection with the rotating threaded rod. The rotating threaded rod drives the second sliding frame to move, and transports the pushing piece to the side of the material rack. The pushing piece starts and pushes the metal wires on the material rack into the second furnace body one by one. During the pushing process, one end of the metal wire to be heated will collide with one end of the heated metal wire in the first and second furnace bodies. As the pushing piece continues to push, the unheated metal wire continues to enter the first and second furnace bodies, and the heated metal wire is pushed to the side of the first furnace body. The entire operation process realizes the mechanized operation of loading, feeding and discharging segmented metal wires, improves the degree of mechanical automation of this process, and improves production efficiency.

[0018] According to the present application, the clamping and lifting frame includes a third motor, a third screw, a first frame, a second telescopic member, a second frame and an insertion rod. The third motor is fixedly connected to the first sliding frame, the output end of the third motor is fixedly connected to one end of the third screw, the third screw is rotatably connected to the first sliding frame, the third screw is threadedly connected to the first frame, the first frame is slidably connected to the first sliding frame, the second telescopic member is fixedly connected to the first frame, the output end of the second telescopic member is fixedly connected to the second frame, the upper part of the second frame is slidably connected to the first frame, and the insertion rod is fixedly connected to the bottom of the second frame.

[0021] According to the present application, the clutch component includes a sixth motor, a bidirectional threaded rod and a threaded block. The threaded blocks are symmetrically arranged. The output end of the sixth motor is fixedly connected to one end of the bidirectional threaded rod. The threaded block is threadedly connected to the bidirectional threaded rod. The two threaded blocks can be threadedly connected to the fifth screw.

[0022] According to the present application, the material rack includes an eighth motor, an eighth lead screw and a movable support frame, the movable support frame is threadedly connected to the eighth lead screw, and the output end of the eighth motor is fixedly connected to one end of the eighth lead screw.

[0023] After the metal wire is heated in the heating furnace, it needs to be removed. The heated metal wire is extremely hot and bright red. According to the production process, it needs to be removed from the furnace and one end placed next to the spring winding device for the spring winding operation. However, if manual removal is used, the operator not only has to face the high temperature environment, but is also very likely to be burned, posing a major safety hazard.

[0024] Once the wire is heated in the furnace, it enters the retrieving phase. At this point, the heated wire is extremely hot, and according to the established production process, it must be removed from the furnace and precisely placed at one end next to the spring winding device. The low level of mechanical automation during this entire retrieving process reduces production efficiency.

[0025] According to the present application, it also includes a material receiving assembly, which includes a moving frame, a third linear slide, a fourth linear slide, a fifth linear slide and a clamping member, the moving frame is arranged on one side of the first furnace body, the sliding end of the third linear slide is slidably connected to the moving frame, the sliding ends of the fourth linear slide and the fifth linear slide are both slidably connected to the sliding end of the third linear slide, and two clamping members are provided, one clamping member is arranged at the bottom of the sliding end of the fourth linear slide, and the other clamping member is arranged at the bottom of the sliding end of the fifth linear slide;

[0026] As the pushing piece continues to advance, the unheated metal wire is continuously fed into the first furnace body and the second furnace body. At the same time, the heated metal wire in the furnace is pushed out synchronously. In this process, the movable frame first starts to move and accurately adjusts its own position. Then, the sliding end of the third linear slide moves, driving the fourth linear slide and the fifth linear slide to move synchronously. The sliding end of the fourth linear slide drives a clamping piece to move, and the sliding end of the fifth linear slide drives another clamping piece to move. The two cooperate with each other to realize the clamping and connecting operation of the heated metal wire. Among them, the clamping end of one clamping piece tightly grasps one end of the metal wire, and the other clamping piece supports the metal wire.

The entire operation process is closely integrated with the loading link, and the heated metal wire is automatically removed from the heating furnace and transferred to the side of the spring winding device, which improves the degree of mechanical automation and thus improves production efficiency.

[0031] According to an embodiment of the present application, a metal wire heating device for spring production has the following beneficial effects:

[0032] 1. During the heating process of metal wires of varying lengths, the two first linear guides play a key regulatory role. With precise drive, one guide drives the first furnace body, while the other guides the second furnace body. This flexible control method enables diverse layouts within the heating furnace:

[0033] On the one hand, in the long metal wire heating scenario: when a long metal wire needs to be heated, the first linear guide rail is driven in reverse, causing the first and second furnace bodies to move to the sides respectively. When the distance between the two is appropriate, the third and fourth furnace bodies are placed between them. At this time, the internal space of the entire heating furnace is greatly increased, and the distance between the furnace bodies can be fine-tuned according to the specific needs of actual production, providing an appropriate heating environment for the long metal wire.

[0034] On the other hand, for heating medium-length metal wires, the first linear guide rail is adjusted appropriately to bring the first and second furnace bodies closer together, with the fourth furnace body positioned between them. This layout rationally allocates the internal space of the heating furnace, precisely meeting the heating requirements of medium-length metal wires.

[0035] On the one hand, in the short metal wire heating scenario, when facing a relatively short metal wire, the first linear slide rail is used to push the first furnace body and the second furnace body toward each other until their sides are tightly fitted together. In this way, the internal space of the heating furnace is reduced, creating a compact space suitable for heating the short metal wire and avoiding waste of space resources.

[0036] With this series of flexible and changeable operations, when heating metal wires of different lengths, the heating furnace can significantly improve the utilization rate of the furnace space by adjusting the length of the internal space, greatly optimizing the adaptability and efficiency of the heating operation.

[0037] 2. While the first and second furnace bodies are initially heating the metal wire, the position of the third furnace body can be flexibly adjusted. The third furnace body can be precisely moved via a second linear slide and cleverly plugged into one side of the first and second furnace bodies. This unique combination design allows the first, second, and third furnace bodies to work together. While the first and second furnace bodies continue to heat the metal wire entering the furnaces, the third furnace body can simultaneously perform secondary heating on the metal wire after the spring is formed. This innovative design eliminates the need for additional heating furnaces for secondary heating of the metal wire after the spring is formed. This simplifies the production process, effectively reduces heat loss caused by the operation of additional equipment, significantly improves energy efficiency, and achieves a rational allocation of thermal energy resources.

DETAILED DESCRIPTION

[0052] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] A metal wire heating device for spring production according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0054] like Figures 1-12As shown, a metal wire heating device for spring production according to an embodiment of the present application includes a heating furnace assembly 100 and a combination assembly 200.

[0055] The heating furnace assembly 100 includes a first furnace body 110, a second furnace body 120 and a first linear slide 130. A sliding side plate 111 is provided on one side of the first furnace body 110 and the second furnace body 120. There are two first linear slides 130. One sliding end of the first linear slide 130 is fixedly connected to the bottom of the first furnace body 110, and the other sliding end of the first linear slide 130 is fixedly connected to the bottom of the second furnace body 120. The combined assembly 200 includes a third furnace body 210, a fourth furnace body 220 and a second linear slide 230. The second linear slide 230 is provided There are two, one sliding end of the second linear slide rail 230 is rotatably connected to the bottom of the third furnace body 210, and the other sliding end of the second linear slide rail 230 is slidably connected to the bottom of the fourth furnace body 220. One side of the third furnace body 210 can be inserted into one side of the second furnace body 120, one side of the fourth furnace body 220 can be inserted into the other side of the third furnace body 210, one side of the first furnace body 110 can be inserted into the other side of the fourth furnace body 220, and one side of the third furnace body 210 can also be inserted into one side of the first furnace body 110, the second furnace body 120, the fourth furnace body 220 and the sliding side plate 111 respectively.

[0056] The following describes the working process of a metal wire heating device for spring production according to a specific embodiment of the present application with reference to the accompanying drawings;

[0057] First, when a long metal wire needs to be heated, the first linear guide rail 130 is driven in the reverse direction to move the first furnace body 110 and the second furnace body 120 to the sides. When the distance between the first furnace body 110 and the second furnace body 120 is appropriate, the third furnace body 210 and the fourth furnace body 220 are placed between them. At this time, the internal space of the entire heating furnace is greatly increased, and the distance between the furnace bodies can be fine-tuned according to the specific needs of actual production, providing an appropriate heating environment for the long metal wire.

[0058] Then, to heat a medium-length metal wire, the first linear guide rail 130 is appropriately adjusted to bring the first furnace body 110 and the second furnace body 120 closer together, with the fourth furnace body 220 positioned between them. This layout rationally allocates the internal space of the heating furnace, precisely meeting the heating requirements of the medium-length metal wire.

[0059] Subsequently, when facing a shorter metal wire, the first linear slide 130 is used to push the first furnace body 110 and the second furnace body 120 toward each other until their sides are tightly fitted together. In this way, the internal space of the heating furnace is shrunk, creating a compact space suitable for heating short metal wires, thus avoiding waste of space resources.

[0060] Finally, the third furnace body 210 is precisely moved by the second linear slide rail 230 and cleverly plugged into one side of the first furnace body 110 and the second furnace body 120. This unique combination design allows the first furnace body 110, the second furnace body 120 and the third furnace body 210 to work together. When the first furnace body 110 and the second furnace body 120 continue to heat the metal wire entering the furnace, the third furnace body 210 can simultaneously perform secondary heating on the metal wire after the spring is formed.

[0061] Therefore, thanks to this innovative design, there is no need to equip additional heating furnaces to reheat the metal wire after spring winding. This not only simplifies the production process, but also effectively reduces the heat energy loss caused by the operation of additional equipment, greatly improves energy utilization efficiency, and realizes the rational allocation of thermal energy resources.

A placement rack 391 is provided on the upper portion of the transfer vehicle 390. The support frame 310 is provided on one side of the second furnace body 120. The first sliding frame 320 and the second sliding frame 340 are both slidably connected to the upper portion of the support frame 310. The rotating end of the rotating threaded rod 360 is rotatably connected to the upper portion of the support frame 310. Then, there are multiple clutch members 370, one clutch member 370 is arranged on one side of the first sliding frame 320, and the other clutch member 370 is arranged on one side of the second sliding frame 340. The clutch member 370 can be threadedly connected to the rotating end of the rotating threaded rod 360. The clamping and lifting frame 330 is symmetrically arranged on the inner side of the first sliding frame 320. The lifting end of the clamping and lifting frame 330 is hung inside one side of the placement frame 391. The metal wire is placed on the upper part of the placement frame 391. The pushing member 350 is arranged at the bottom of the second sliding frame 340, and the material rack 380 is arranged on one side of the second furnace body 120;

[0074] At the beginning of the loading operation, a placement rack 391 is first placed stably on the transfer vehicle 390, and the metal wire segments are neatly stacked on the placement rack 391. Then, another placement rack 391 is laid on top of the placed metal wires, and the metal wire segments are continued to be placed on the placement rack 391. The operation is circulated in this way to achieve orderly stacking of the metal wire segments on the transfer vehicle 390. Subsequently, the transfer vehicle 390 is moved to the side below the support frame 310, the equipment is started, and the threaded rod 360 is rotated to start operation. It is located on the side of the first sliding frame 320. The clutch member 370 is then threadedly connected to the rotating threaded rod 360, thereby driving the first sliding frame 320 to move, and the two clamping and lifting frames 330 are transported to the top of the transfer vehicle 390. At this time, the clamping and lifting frames 330 not only produce horizontal displacement, but also their bottoms perform lifting and lowering movements, accurately inserting the bottoms into one side of the placement frame 391. Relying on the coordinated movement of the clamping and lifting frames 330 and the first sliding frame 320, the segmented metal wires on the placement frame 391 are steadily lifted and transferred to the material rack 380. The material rack 380 is used to lift the middle of the segmented metal wires. After forming effective support, the lifting end of the clamping and lifting frame 330 gradually descends, so that the placement frame 391 is smoothly separated from the metal wire. At this time, the side of the second furnace body 120 close to the support frame 310 is in an open state, the clutch 370 on the first sliding frame 320 is disconnected from the rotating threaded rod 360, and the clutch 370 on the second sliding frame 340 is threaded with the rotating threaded rod 360. The rotating threaded rod 360 drives the second sliding frame 340 to move, and transports the pusher 350 to the side of the material rack 380. The pusher 350 is started, and the material racks are pushed one by one. The metal wire on 380 is pushed into the second furnace body 120. During the pushing process, one end of the metal wire to be heated will collide with one end of the metal wire that has been heated in the first furnace body 110 and the second furnace body 120. As the pushing piece 350 continues to push, the unheated metal wire continues to enter the first and second furnace bodies 120, while the heated metal wire is pushed out to the side of the first furnace body 110. The entire operation process realizes the mechanized operation of loading, feeding and discharging segmented metal wires, improves the degree of mechanical automation of this process, and improves production efficiency.
