Description

Technical Field

[0001] This application relates to the technical field of submerged arc welding wire drying equipment, specifically to a submerged arc welding wire drying box with temperature control function. Background Technology

[0002] Drying is an essential step in the manufacturing process of submerged arc welding wire (SAW) to remove surface moisture and ensure welding quality. However, traditional SAW drying methods have several drawbacks. Firstly, common drying equipment typically uses simple heating methods, resulting in uneven heat distribution. This leads to significant differences in the drying degree of SAW wires in different locations within the drying chamber, with some wires being over-dried while others are under-dried, severely impacting product quality stability and consistency. Secondly, during the drying process, SAW wires are often in a relatively static state, making it difficult for surface moisture to fully contact and evaporate with the hot air, resulting in low drying efficiency and increased production costs and time. Furthermore, for multi-layered SAW wires, the lack of an effective synchronous drying control mechanism makes it difficult to guarantee consistent drying results across all layers.

[0003] Therefore, in order to meet the demand of modern manufacturing for high-quality submerged arc welding wire, there is an urgent need for a submerged arc welding wire drying oven that can improve drying efficiency, ensure uniform drying effect, and achieve synchronous drying of each layer of welding wire. Summary of the Invention

[0004] To address the aforementioned technical problems, this application solves the issues of uneven heat transfer within the drying chamber, inconsistent drying effects due to positioning deviations during the installation of the bearing plate, and difficulty in fully exposing the surface moisture of the welding wire to hot air, as well as the difficulty in synchronously shaking the bearing plate, which in turn affect the drying efficiency and quality of existing submerged arc welding wire drying boxes.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a submerged arc welding wire drying box with temperature control function, comprising a drying box assembly, a shaking assembly, and a driving assembly. The drying box assembly includes a heater, a copper tube, a drying chamber, and a support plate. The heater and the drying chamber are disposed on the box body. The copper tube is fixedly connected to the heater. Multiple support plates for carrying welding wire are disposed on the drying chamber. The heater controls the copper tube to release heat energy to dry the submerged arc welding wire in the drying chamber.

[0006] The vibration assembly includes a long shaft, a short shaft, a vibration block, and a front mounting rod. The front mounting rod is fixedly mounted on the drying chamber, the long shaft and the short shaft are rotatably mounted on the front mounting rod, and the vibration block is fixedly mounted on the bearing plate. The vibration block is provided with a friction surface.

[0007] The drive assembly includes a vertical slide, a rear push-pull rod, and a rectangular slider. The rectangular slider is fixedly mounted on a long shaft. The rear push-pull rod has a groove, and the rectangular slider cooperates with the groove of the rear push-pull rod. The end of the rear push-pull rod away from the rectangular slider is rotatably connected to the vertical slide. The vertical slide slides vertically on the shaking assembly, and the rectangular slider drives the shaking assembly to shake.

[0008] Preferably, the bearing plate is provided with four shaking blocks, and a long shaft is in contact with two shaking blocks at the same time. A front mounting rod, the bearing plate, the four shaking blocks, the two long shafts and the short shafts form a set of dehumidification components. The drying chamber is provided with multiple sets of dehumidification components, and the moisture on the surface of the submerged arc welding wire on each layer of bearing plate is rapidly evaporated through the multiple sets of dehumidification components.

[0009] Preferably, the vibration component includes an external gear and an internal gear. The external gear is fixedly mounted on a long shaft, and the internal gear is fixedly mounted on a short shaft. The external gear meshes with the internal gear to achieve reverse rotation of the long shaft and the short shaft.

[0010] Preferably, the length of the long shaft is smaller than the length of the short shaft.

[0011] Preferably, the drive assembly includes an electric cylinder, a front push-pull rod, an inner slide rod, and an outer slide rod. The electric cylinder is fixedly mounted on the housing, and its output end is rotatably connected to the front push-pull rod. The end of the front push-pull rod away from the electric cylinder is rotatably connected to the upper end of the inner slide rod. The outer slide rod is vertically mounted on the housing, and the inner slide rod slides vertically on the outer slide rod. The lower end of the outer slide rod is fixedly connected to two vertical slide frames, and the vertical slide frames on both sides are moved synchronously by controlling the outer slide rod.

[0012] Preferably, the shaking assembly includes a back frame and a rear mounting plate. The back frame is fixedly mounted on the housing and has multiple holes on it. The long shaft rotates through these holes. The rear mounting plate is fitted onto the long shaft and the short shaft and is fixedly mounted on the drying chamber by bolts.

[0013] The technical solution provided in this application has the following advantages compared with the prior art:

[0014] 1. This application achieves precise centering of the bearing plate by setting an inner groove-shaped friction surface with a deep central depression and gradually shallower sides on the shaking block. When the bearing plate is installed on the long shaft, the vertical center plane of the shaking block is made to coincide with the axis of the long shaft, which drives the bearing plate to move to the center position of a certain horizontal plane in the drying chamber. This solves the problem of uneven heat transfer on both sides during drying caused by the positioning deviation of the bearing plate, and improves the consistency of welding wire drying.

[0015] 2. This application uses an electric cylinder in the drive assembly to drive the front push-pull rod, inner slide rod, and outer slide rod in a coordinated manner, causing the vertical slide to move vertically back and forth. This, in turn, drives the rear push-pull rod to rotate the long shaft. Simultaneously, the engagement of the outer and inner gears in the vibration assembly enables the long shaft and short shaft to rotate in opposite directions. When the bearing plate moves to the edge, the short shaft blocks and pushes back the vibration block, achieving synchronous lateral reciprocating vibration of the bearing plate. This solves the problem of insufficient moisture exposure on the surface of the welding wire due to the difficulty in synchronous vibration of the bearing plate, improves the contact efficiency between the welding wire and the hot air, and thus enhances the drying efficiency.

[0016] 3. This application uses three tube racks in the drying chamber assembly to install and fix the copper tubes, so that the copper tubes are distributed in a circle to heat the air on the side of the drying chamber. The heat enters the interior through the ventilation opening on the side of the drying chamber to achieve overall heat transfer. In conjunction with the shaking component, the bearing plate shakes to expose the moisture on the surface of the welding wire, so as to achieve full contact between the welding wire and the hot air. This solves the problems of uneven heat transfer in the drying chamber and insufficient evaporation of moisture on the surface of the welding wire, and improves the overall drying effect of the welding wire.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] like Figures 1 to 8 As shown, a submerged arc welding wire drying box with temperature control function includes a drying box assembly 100, a vibration assembly 200, and a drive assembly 300. The drying box assembly 100 includes a heater 102, a copper tube 103, a drying chamber 105, and a support plate 107. Three support seats 106 are fixedly installed on the box body 101, and the drying chamber 105 is fixedly installed on the three support seats 106. The support seats 106 separate the drying chamber 105 from the bottom of the box body 101, and a certain distance is also formed between the sides of the drying chamber 105 and the box body 101, thus forming an isolation space. Three tube racks 104 are fixedly installed on the box body 101, and the copper tube 103 is installed on the three tube racks 104. The heater 102 and the drying chamber 105 are installed on the housing 101. The copper tube 103 is fixedly connected to the heater 102. The drying chamber 105 is provided with multiple support plates 107 for carrying welding wire. The heater 102 controls the copper tube 103 to release heat energy to dry the submerged arc welding wire in the drying chamber 105.

[0029] Specifically, the drying oven assembly 100 is equipped with an electronic control system and a touch screen. The corresponding function module can be selected via the touch screen to control the start-up of the heater 102 and the drive assembly 300. The oven body 101 is equipped with a door panel. The attached diagram shows the internal structure, but since the door panel is a basic component in this field and can be easily conceived and obtained, its structure is not shown.

[0030] In use, the submerged arc welding wire that needs to be dried is placed in the support tray 107. Then, the operator places the support tray 107 containing the submerged arc welding wire into the drying chamber 105 and supports it with the shaking component 200. Then, the heater 102 is started by controlling the touch screen and the electronic control system to heat the copper tube 103. The copper tube 103 is wrapped around multiple tube racks 104 to heat the side air of the drying chamber 105. The heat enters the interior of the drying chamber 105 through the ventilation holes on the side of the drying chamber 105 and is transferred to the entire interior of the drying chamber 105, thereby drying the submerged arc welding wire on the support tray 107.

[0031] like Figure 7 As shown, the shaking assembly 200 includes a long shaft 202, a short shaft 203, a shaking block 207, and a front mounting rod 208. The front mounting rod 208 is fixedly installed on the drying chamber 105. The front mounting rod 208 is provided with an inclined surface for the installation of the support plate 107, which facilitates the sliding of the support plate 107 into the drying chamber 105. A buffer strip is provided on the drying chamber 105 at the same level as 108 to buffer the movement of the support plate 107 and prevent the support plate 107 from colliding with the inner wall of the drying chamber 105. The long shaft 202 and the short shaft 203 are rotatably mounted on the front mounting rod 208. The vibrating block 207 is fixedly mounted on the bearing plate 107. The vibrating block 207 is provided with a friction surface, which is a concave groove structure with a deep center and gradually shallower sides. When the bearing plate 107 is mounted on the long shaft 202, the structure of the friction surface of the vibrating block 207 can make the vertical center plane of the vibrating block 207 coincide with the axis of the long shaft 202, thereby driving the bearing plate 107 to move and place it at the center position on a certain horizontal plane in the drying chamber 105. During subsequent drying, the heat transfer on both sides is more uniform, and the vibration is more synchronized when the drive assembly 300 is used.

[0032] like Figure 6As shown, the drive assembly 300 includes a vertical slide 305, a rear push-pull rod 306, and a rectangular slider 307. The rectangular slider 307 is fixedly mounted on the long shaft 202. The rear push-pull rod 306 is provided with a sliding groove, which is rectangular and fits the rectangular shape of the rear push-pull rod 306. The rectangular slider 307 cooperates with the sliding groove of the rear push-pull rod 306. The end of the rear push-pull rod 306 away from the rectangular slider 307 is rotatably connected to the shaft on the vertical slide 305. The vertical slide 305 slides vertically on the vibration assembly 200, and the rectangular slider 307 drives the vibration assembly 200 to vibrate.

[0033] Specifically, the vertical slide 305 is equipped with multiple shafts, each with an inner end of a rear push-pull rod 306 rotatably mounted on it. The outer end of each rear push-pull rod 306 is slidably connected to a rectangular slider 307 on a long shaft 202. Therefore, by controlling the vertical movement of the vertical slide 305, the inner ends of the rear push-pull rods 306 can be moved up and down. Figure 6 In the indicated state, when the vertical slide 305 moves downward, it causes the inner end of the rear push-pull rod 306 to move downward. Consequently, the outer end of the rear push-pull rod 306, because it is mounted on the rectangular slider 307, slides outward on the rectangular slider 307, i.e., away from the vertical slide 305. When the inner end of the rear push-pull rod 306 moves downward, the angle of the rear push-pull rod 306 changes. This causes the rectangular slider 307 and the long shaft 202 to rotate around the axis of the long shaft 202 through the rectangular shape of the rear push-pull rod 306's groove. The long shaft 202 then contacts the friction surface of the shaking block 207, causing the shaking block 207 and the bearing plate 107 to move laterally on the horizontal plane. This causes the submerged arc welding wire in the bearing plate 107 to shake, exposing the surface moisture and allowing it to fully contact the hot air, thus improving the drying efficiency and effect.

[0034] like Figure 3 and Figure 7As shown, four vibrating blocks 207 are provided on the support plate 107, located at the front and rear ends of the support plate 107, i.e., the ends away from the back frame 201 and the ends close to the back frame 201, respectively. A long shaft 202 simultaneously contacts two vibrating blocks 207, supporting the support plate 107 through the contact between the two vibrating blocks 207 and the long shaft 202. A short shaft 203 intermittently contacts the two vibrating blocks 207, i.e., when the vibrating blocks 207 move to the outer edge, the short shaft 203 forms a shallow groove on the friction surface of the vibrating block 207. A front mounting rod 208, the support plate 107, the four vibrating blocks 207, the two long shafts 202, and the short shaft 203 form a dehumidification assembly. Multiple sets of dehumidification assemblies are provided on the drying chamber 105. The vibration of the support plate 107 by the multiple sets of dehumidification assemblies causes the moisture on the surface of the submerged arc welding wire on each layer of the support plate 107 to evaporate rapidly.

[0035] like Figure 7 As shown, the vibration component 200 includes an external gear 204 and an internal gear 205. The external gear 204 is fixedly mounted on the long shaft 202, and the internal gear 205 is fixedly mounted on the short shaft 203. The external gear 204 meshes with the internal gear 205 to realize the opposite rotation of the long shaft 202 and the short shaft 203.

[0036] Specifically, when the long shaft 202 is driven by the drive assembly 300 to rotate a certain angle, the long shaft 202 drives the short shaft 203 to rotate in the opposite direction through the meshing of the external gear 204 and the internal gear 205. This causes the long shaft 202 to drive the vibrating block 207 to move through contact with its friction surface. When the short shaft 203 contacts the friction surface of the vibrating block 207, its reverse rotation blocks and pushes the vibrating block 207, causing it to vibrate at that position. When the drive assembly 300 controls the direction of the long shaft 202 to rotate, the rotation directions of the long shaft 202 and the short shaft 203 also change, becoming opposite. This causes the long shaft 202 to drive the vibrating block 207 to move in the opposite direction, while the short shaft 203... Because the contact with the vibrating block 207 is insufficient, it will not continue to block the movement of the vibrating block 207 due to the reversal. As a result, the long shaft 202 drives the vibrating block 207 to move to a similar position on the other side. That is, the long shaft 202 and the short shaft 203 on the other side also exhibit the aforementioned situation, that is, the short shaft 203 on the other side contacts the friction surface of the vibrating block 207, blocking the vibrating block 207 from moving to that side. Then, the drive assembly 300 controls the vibrating assembly 200 to change the rotation direction again. This process is repeated, causing the vibrating block 207 to drive the carrier plate 107 to move laterally back and forth. This back and forth movement is used to shake the submerged arc welding wire carried in the carrier plate 107, causing it to change the orientation of the outer surface, so that the surface moisture can evaporate quickly and improve the drying efficiency.

[0037] like Figures 6 to 7 As shown, the size of the long shaft 202 is smaller than the size of the short shaft 203.

[0038] Specifically, because the long shaft 202 and the short shaft 203 have different specifications, and the short shaft 203 is located inside the long shaft 202, when the bearing plate 107 moves outward, the friction surface of the vibrating block 207 contacts the long shaft 202 first. After moving a certain distance, the friction surface of the vibrating block 207 contacts the short shaft 203. The contact between the short shaft 203 and the vibrating block 207 limits the movement of the bearing plate 107 until all the vibrating blocks 207 have moved to that position. Then, with the control of the vibrating component 200 by the drive component 300, the multiple vibrating blocks 207 synchronously change their moving direction, thereby causing the multiple bearing plates to move outward. 107. To maintain synchronization, when placing the carrier plate 107, due to the installation position, the contact points between the vibrating block 207 and the long shaft 202 are different, resulting in multiple carrier plates 107 being misaligned vertically. During the first movement, the short shaft 203 blocks the vibrating block 207 to stay at the boundary position for a while, waiting for all the vibrating blocks 207 to contact the short shaft 203. Therefore, the vibrating blocks 207 and the carrier plate 107 are now vertically aligned. Subsequently, when controlling their reciprocating movement, they can move synchronously, which facilitates unified control of the submerged arc welding wire on the carrier plate 107, controlling the surface drying effect and efficiency, and keeping them consistent.

[0039] like Figures 4 to 6 As shown, the drive assembly 300 includes an electric cylinder 301, a front push-pull rod 302, an inner slide rod 303, and an outer slide rod 304. The electric cylinder 301 is fixedly installed on the housing 101. The output end of the electric cylinder 301 is rotatably connected to the front push-pull rod 302. The end of the front push-pull rod 302 away from the electric cylinder 301 is rotatably connected to the upper end of the inner slide rod 303. The outer slide rod 304 is vertically installed on the housing 101. The inner slide rod 303 slides vertically on the outer slide rod 304. The lower end of the outer slide rod 304 is fixedly connected to two vertical slide frames 305. The outer slide rod 304 controls the synchronous movement of the vertical slide frames 305 on both sides.

[0040] like Figure 5 and Figure 6As shown, during use, the electric cylinder 301 is started by controlling the electric control system. The output end of the electric cylinder 301 pulls the lower end of the front push-pull rod 302 away from the outer slide rod 304. As a result, the upper end of the front push-pull rod 302 pulls the inner slide rod 303 to slide downward on the outer slide rod 304. As a result, the lower end of the inner slide rod 303 pushes the vertical slides 305 on both sides to slide downward on the back frame 201. As a result, the vertical slide 305 pulls the inner end of the rear push-pull rod 306 through multiple shafts. The outer end of the rear push-pull rod 306 drives the rectangular slider 307 and the long shaft 202 to rotate through the slide groove, thereby controlling the rotation of the long shaft 202 and the short shaft 203. Furthermore, the reciprocating push and pull of the electric cylinder 301 controls the vertical slide 305 to move up and down in the vertical direction, thereby controlling the rotation direction of the long shaft 202 and the short shaft 203.

[0041] like Figure 6 and Figure 7 As shown, the shaking assembly 200 includes a back frame 201 and a rear mounting plate 206. The back frame 201 is fixedly mounted on the housing 101. The back frame 201 has multiple holes on it, through which the long shaft 202 rotates. The rear mounting plate 206 is fitted onto the long shaft 202 and the short shaft 203. The rear mounting plate 206 is fixedly mounted on the drying chamber 105 by bolts.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
