Description

Technical Field

[0001] The present invention belongs to the technical field of wire feeding equipment, and more specifically, relates to a continuous wire feeding equipment for hydraulic cylinder welding. Background Art

[0002] In the field of hydraulic cylinder welding, wire feeding and welding operation stability, safety, and weld quality are key considerations. However, existing welding methods and equipment have many problems that need to be solved.

[0003] In traditional hydraulic cylinder welding, wire feeding relies primarily on manual manipulation. This makes it difficult to maintain consistent wire length each time, and the manipulation distance cannot be precisely controlled. This leads to frequent quality issues such as missed welds and missing welds, severely impacting welding stability and finished product quality. Furthermore, manual manipulation is difficult to control the angle of the wire tip, further reducing welding controllability.

[0004] In terms of welding safety, existing welding equipment does not provide adequate protection for operators' fingers. The molten iron splashing during welding can easily burn the operator's fingers, especially when handling the welding wire flexibly. This increases the probability of fingers being exposed to dangerous conditions, posing a threat to the operator's personal safety.

[0005] From the perspective of improving welding quality, traditional welding methods cause uneven transition of the molten droplet from the end of the wire into the molten pool during combustion, which can easily produce large droplets or uneven dripping, leading to weld spatter and affecting weld quality. Furthermore, gases and impurities in the molten pool cannot fully escape, increasing the probability of welding defects such as porosity and slag inclusions.

[0006] Furthermore, existing welding equipment has limited adaptability to varying wire thicknesses. Typically, a single device is only compatible with specific wire specifications. When welding wires of varying thicknesses, the entire device must be replaced or complex adjustments must be made, which is cumbersome and costly. Furthermore, during wire feeding, if the main drive assembly and the wire do not fully contact each other, it becomes difficult to ensure stable wire movement, affecting the continuity and stability of the weld.

[0007] In addition, if impurities and rust on the surface of the welding wire are not removed, it will affect its melting effect during welding, thereby affecting the welding quality. However, existing welding equipment often lacks online rust removal function for welding wire, or the rust removal effect is poor.

[0008] In summary, the existing hydraulic cylinder welding technology has many shortcomings in terms of wire feeding stability, operational safety, welding quality improvement, wire adaptability and wire rust removal, and cannot meet the requirements of modern industry for high-quality and high-efficiency hydraulic cylinder welding.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the rotation of the first driving wheel assists in driving the welding wire body to move downward, and at the same time, the continuous rotation of the driving disk will drive the rotation of the trapezoidal push plate, and the multiple trapezoidal push plates will continuously drive the welding wire body to rotate. During hydraulic cylinder welding, the welding wire body will continue to shorten when burning. At this time, it is necessary to manually use fingers to continuously push the welding wire body forward. Manual pushing is prone to different lengths each time, and the length and distance of each push are uncontrollable, which leads to problems such as leaking welds and missing welds during welding. This device uses a wire feeder to drive the welding wire body to move downward continuously, and there is no need for manual fingers to continuously move the welding wire body downward, which greatly improves the stability of welding. At the same time, holding the wire feeder can better control the angle of the end of the welding wire body, further improving the controllability of welding.

[0017] In the present invention, the user's thumb fits into the start button. When welding the hydraulic cylinder, the user's remaining three fingers are located above the protective cover, and the protective cover is tilted backward, so the user's remaining three fingers can be well protected, effectively preventing the user's fingers from being injured by splashing molten iron during welding. At the same time, both ends of the welding wire feeder are provided with tapered bodies, which can facilitate the insertion of the welding wire body and the other end can facilitate the position and length of the welding wire body to be clearly seen during welding, providing convenience for hydraulic cylinder welding.

[0018] In the present invention, the second motor is started to drive the first gear and the first driving wheel to rotate. The rotation of the first driving wheel drives the welding wire body to move downward. The two sets of auxiliary driving components are located between the two sets of main driving components, which can play the effect of assisting in driving the welding wire body to move. At the same time, the rotation of the first gear will drive the second gear to rotate, and the rotation of the second gear will drive the driving disk to rotate. The rotation of the driving disk drives the three trapezoidal push plates on the side to rotate. When the trapezoidal push plates rotate and contact the welding wire body, they will exert a certain lateral thrust on the welding wire body, and the welding wire body will rotate slightly at a small angle. The continuous rotation of multiple trapezoidal push plates will drive the welding wire body to rotate continuously. The rotating welding wire body can make the molten droplets at the end of the welding wire body transition to the molten pool more evenly, reduce spattering caused by excessively large or uneven dripping of molten droplets, improve welding stability, and the rotating action can slightly stir the molten pool, helping gases (such as hydrogen, oxygen) and impurities in the molten pool to escape more fully, thereby reducing the generation rate of welding defects such as pores and slag inclusions.

[0019] When the wheel frame is in a state of being stretched, the guide wheel and the connecting sleeve are pulled back and forth, and the guide wheel and the connecting sleeve are pulled back and forth to move relative to each other, so that the guide wheel can move relative to each other and the welding wire body can be adjusted.

[0020] In the present invention, when the welding wire body moves down to the inside of the rust removal component, the outer wall of the welding wire body fits with multiple friction balls, and friction is generated between the multiple friction balls and the surface of the welding wire body, which can remove impurities and rust on the surface of the welding wire body, ensuring that the welding wire body can be melted just right when welding to the hydraulic cylinder, and the back of each telescopic frame is supported by multiple third springs, so as to maintain the fit between the friction balls and the welding wire body, and at the same time can adapt to welding wire bodies of different thicknesses.

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0024] See also Figures 1-8The present invention provides a continuous wire feeding device for hydraulic cylinder welding, comprising a wire feeder 1 and a wire body 14. A guide groove 16 is provided inside the wire feeder 1, and the wire body 14 is located inside the guide groove 16. At least two groups of auxiliary drive components 2 and a main drive component 4 are provided inside the wire feeder 1. Each group of auxiliary drive components 2 and main drive components 4 are located on both sides of the wire body 14. The main drive component 4 is used to control the movement of the wire body 14 in the wire feeder 1. The auxiliary drive component 2 is used to assist the main drive component 4 in conveying wire bodies 14 of different sizes. The auxiliary drive component 2 includes a rotatable wheel frame 2. 1. The first driving wheel 31 and the driving disc 34, the rotating wheel frame 21 and the first driving wheel 31 are used to clamp the two sides of the welding wire body 14, and the side wall of the driving disc 34 is provided with at least two movable trapezoidal push plates 36. When the driving disc 34 rotates, the driving disc 34 drives the welding wire body 14 to rotate through the trapezoidal push plates 36, and the rotation of the first driving wheel 31 is used to assist the welding wire body 14 to move in the welding wire feeder 1. The main driving assembly 4 includes a rotatable second driving wheel 42 and a third driving wheel 45. The second driving wheel 42 and the third driving wheel 45 are located on both sides of the welding wire body 14, and the rotation of the second driving wheel 42 and the third driving wheel 45 can drive The welding wire body 14 is driven to move downward. When the hydraulic cylinder is welding, the user first inserts the welding wire body 14 from the end of the welding wire feeder 1. When the welding wire body 14 contacts the main drive assembly 4, the user presses the start button 11 with his thumb. At this time, the main drive assembly 4 and the auxiliary drive assembly 2 are started, and the second drive wheel 42 and the third drive wheel 45 inside the main drive assembly 4 rotate to drive the welding wire body 14 to move downward. When the end of the welding wire body 14 contacts the auxiliary drive assembly 2, the first drive wheel 31 rotates to assist in driving the welding wire body 14 to move downward. At the same time, the continuous rotation of the drive disk 34 will drive the trapezoidal push plate 36 to rotate, and multiple trapezoidal push plates 36 will The welding wire body 14 is continuously driven to rotate. During hydraulic cylinder welding, the welding wire body 14 will continue to shorten when burning. At this time, it is necessary to manually use fingers to continuously move the welding wire body 14 forward. Manual moving is prone to different lengths each time, and the length and distance of each moving are uncontrollable, resulting in problems such as leaking welds and missing welds during welding. The device uses the welding wire feeder 1 to drive the welding wire body 14 to move downward continuously, eliminating the need for manual use of fingers to continuously move the welding wire body 14 downward, thereby greatly improving the stability of welding. At the same time, holding the welding wire feeder 1 can better control the angle of the end of the welding wire body 14, further improving the controllability of welding. A rust removal component 5 is fixedly installed inside the welding wire feeder 1 near the bottom end. The rust removal component 5 includes two mounting plates 46 and at least two telescopic frames 48, and the welding wire body 14 is inserted into the rust removal component 5. When the welding wire body 14 moves out of the rust removal component 5, the end of the welding wire body 14 will be blocked and decelerated by the rust removal component 5 as a whole, thereby ensuring the stability of the welding wire body 14 during movement, preventing the welding wire body 14 from shaking during movement due to inconsistent transmission of multiple groups of auxiliary drive components 2 and main drive components 4, and further improving the stability of the welding wire body 14 when welding the hydraulic cylinder.

[0025] In this embodiment, Figures 1 to 3 The upper and lower ends of the welding wire feeder 1 are fixedly installed with a cone 13, and a start button 11 is fixedly installed on the side wall of the welding wire feeder 1. A protective cover 12 is fixedly installed on the surface of the cone 13 near the bottom of the welding wire feeder 1, and the inclined mouth above the protective cover 12 is away from the start button 11. At least two rubber sleeves 15 are fixedly installed inside the guide groove 16, and the welding wire body 14 is inserted into the rubber sleeve 15. The user holds the welding wire feeder 1 with the index finger and thumb, and the user's thumb fits with the start button 11. When welding the hydraulic cylinder, the user's remaining three fingers are located above the protective cover 12, and the protective cover 12 is tilted backward, so the user's remaining three fingers can be well protected, effectively preventing the user's fingers from being injured by splashing molten iron during welding. At the same time, both ends of the welding wire feeder 1 are provided with cones 13, which can facilitate the insertion of the welding wire body 14, and the other end can facilitate the position and length of the welding wire body 14 during welding, thereby improving the convenience of hydraulic cylinder welding.

[0026] In this embodiment, Figure 2 、 Figure 4 and Figure 5The auxiliary drive assembly 2 also includes a second motor 29 and a driver 22. The first gear 3 is fixedly mounted on the output shaft surface of the second motor 29, and the second gear 33 is fixedly mounted on the back of the drive disk 34, and the second gear 33 is meshed with the first gear 3 up and down. The side wall of each drive disk 34 is provided with at least two inner slide grooves 35, and each trapezoidal push plate 36 is installed in the inner slide groove 35, and a second spring 39 is fixedly mounted between the trapezoidal push plate 36 and the inner wall of the inner slide groove 35. Each trapezoidal push plate 36 is located in an inclined state in the inner slide groove 35, and the trapezoidal push plate 36 is inclined outward and the protruding side faces the welding wire body 14. The end of the side wall of each trapezoidal push plate 36 is fixedly mounted with an anti-slip pad 37, and the side wall of each anti-slip pad 37 is provided with at least two grooves 38. When the welding wire body 14 moves to the auxiliary drive assembly 2, the second motor 29 starts to drive the first gear 3 and the first driving wheel 31 to rotate, and the first driving wheel 31 rotates to drive the welding wire The main body 14 moves downward, and the two sets of auxiliary drive assemblies 2 are located between the two sets of main drive assemblies 4, which can assist in driving the welding wire body 14 to move. At the same time, the rotation of the first gear 3 will drive the second gear 33 to rotate, and the rotation of the second gear 33 will drive the drive disc 34 to rotate. The rotation of the drive disc 34 drives the three trapezoidal push plates 36 on the side to rotate. When the trapezoidal push plates 36 rotate and contact the welding wire body 14, they will exert a certain lateral thrust on the welding wire body 14, and the welding wire body 14 will rotate slightly at a small angle. The continuous rotation of multiple trapezoidal push plates 36 will drive the welding wire body 14 to rotate continuously. The rotating welding wire body 14 can make the molten droplets at the end of the welding wire body 14 transition more evenly to the molten pool, reduce spatter caused by excessively large or uneven dripping of molten droplets, and improve welding stability. The rotating action can slightly stir the molten pool, helping gases (such as hydrogen, oxygen) and impurities in the molten pool to escape more fully, thereby reducing the generation rate of welding defects such as pores and slag inclusions; When the trapezoidal push plate 36 is in contact with the welding wire body 14, the anti-slip pad 37 on the side of the trapezoidal push plate 36 will contact the welding wire body 14. A plurality of grooves 38 are provided on the surface of the anti-slip pad 37, thereby increasing the friction between the anti-slip pad 37 and the welding wire body 14. At the same time, the back of the trapezoidal push plate 36 is supported by two second springs 39, which can maintain the fit between the trapezoidal push plate 36 and the welding wire body 14. While providing a push for the welding wire body 14 to rotate, it can keep itself retracted into the inner slide groove 35.

[0027] In this embodiment, Figure 2 、 Figure 4 、 Figure 6 and Figure 7The screw rod at the end of each driver 22 is sleeved with a driving frame 28, and a rotating shaft 27 is rotatably installed between the side wall of each rotary wheel frame 21 and the driving frame 28, and the driving frame 28 is slidably installed inside the wire feeder 1, and the driver 22 is fixed inside the wire feeder 1. The middle part of each rotary wheel frame 21 is fixedly installed with a telescopic cylinder 24, and a first spring 25 is provided inside the telescopic cylinder 24. A connecting sleeve 23 is fixedly installed in the middle part of the rotary wheel frame 21 located on the outer ring of the telescopic cylinder 24. A limiting frame 26 is provided above the rear side of the rotary wheel frame 21, and the limiting frame 26 is fixed inside the wire feeder 1, and the inner walls on both sides of the rotary wheel frame 21 are fitted with both sides of the limiting frame 26. Due to the different thicknesses of different welding wire bodies 14, when encountering a thinner welding wire body 14, the driver 22 is started (the driver 22 consists of a motor and a screw rod, and the screw rod is fixedly connected to the output shaft of the driver 22), and the driver 22 drives the driving frame 28 to move inward through the screw rod, driving The moving frame 28 moves through the rotating shaft 27 to drive the rotating wheel frame 21 to move. The more the rotating wheel frame 21 moves inward, the smaller the angle of the limiting frame 26 becomes. At this time, the first spring 25 inside the telescopic cylinder 24 will pull the two ends of the rotating wheel frame 21 inward, and the connecting sleeve 23 will retract. At this time, the rotating wheel frame 21 and the connecting sleeve 23 can fit with the welding wire body 14. Similarly, when the welding wire body 14 is thicker, the driver 22 drives the driving frame 28 to move outward, the rear angle of the limiting frame 26 becomes larger, and the two ends of the rotating wheel frame 21 are in contact with each other. The end will be expanded, and at this time the connecting sleeve 23 is stretched, and can fit with the thicker welding wire body 14. By designing the turntable frame 21 to be variable in size and the distance of the turntable frame 21 can be changed, it can adapt to welding wire bodies 14 of different thicknesses, and the turntable frame 21 can fit with welding wire bodies 14 of different thicknesses, so that when the main drive component 4 cannot fully fit with the welding wire body 14, the auxiliary drive component 2 can ensure that the welding wire body 14 can move downward stably.

[0028] In this embodiment, Figure 2 and Figure 4 The main drive assembly 4 also includes a third motor 41. The output shaft of the third motor 41 is fixedly connected to the side wall of the second drive wheel 42, and a third gear 43 is fixedly installed on the surface of the output shaft of the third motor 41. A fourth gear 44 is fixedly installed on the side wall of the third drive wheel 45, and the third gear 43 is engaged with the fourth gear 44. When the welding wire body 14 is moved downward, the third motor 41 drives the third gear 43 and the second drive wheel 42 to rotate. At the same time, the third gear 43 drives the third drive wheel 45 to rotate through the fourth gear 44. The synchronous rotation of the second drive wheel 42 and the third drive wheel 45 can drive the welding wire body 14 to move downward.

[0029] In this embodiment, Figure 2 、 Figure 4 、 Figure 8 and Figure 9The two mounting plates 46 are buckled relative to each other up and down, and the inner rings of the two mounting plates 46 are equidistantly provided with at least two arc grooves 47, and the back of each telescopic frame 48 faces the arc groove 47, and at least two third springs 51 are fixedly installed between the back of each telescopic frame 48 and the side wall of the arc groove 47, and a friction ball 49 is rotatably installed inside each telescopic frame 48, and each friction ball 49 faces the welding wire body 14. When the welding wire body 14 moves down to the inside of the rust removal assembly 5, the outer wall of the welding wire body 14 fits with multiple friction balls 49, and friction between the multiple friction balls 49 and the surface of the welding wire body 14 generates friction, which can remove impurities and rust on the surface of the welding wire body 14, ensuring that the welding wire body 14 can be melted just when welding to the hydraulic cylinder, and the back of each telescopic frame 48 is supported by multiple third springs 51, so as to maintain the fit between the friction ball 49 and the welding wire body 14, and at the same time can adapt to welding wire bodies 14 of different thicknesses.
