During use, the taut welding wire generates thrust, pushing the gravity hammer upwards and compressing the second spring.

Description

Technical Field

[0001] This utility model relates to the field of welding wire reels, specifically a welding wire reel that can tighten welding wire. Background Technology

[0002] Welding wire is a metal wire used as filler metal or as a conductor for welding. After the welding wire is produced, it needs to be wound on a wire reel and then placed on a wire feeder to connect the welding wire to the welding machine. After the welding wire is taut, it is pulled to let the wire out freely for welding.

[0003] The resistance between the current wire spool and the wire spool support is relatively small, which makes it easy for the wire to loosen during use, affecting the welding quality and causing wire waste. At the same time, the instantaneous retraction of the wire after it is cut can easily cause the coil to burst, making the coil messy and affecting the next use.

[0004] To address this, we propose a wire spool that can tighten the welding wire. Utility Model Content

[0005] This utility model proposes a wire reel that can tighten the welding wire.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wire reel that can tighten welding wire, comprising a support assembly, a fastening assembly fixedly connected to the middle of the upper surface of the support assembly, a protective assembly fixedly connected to the edge of the upper surface of the support assembly, and a wire reel assembly rotatably connected to the outer surface of the support assembly.

[0007] The fastening assembly includes a fixing plate, the lower surface of which is connected to the middle of the upper surface of the bracket assembly by bolt thread. A telescopic rod is fixedly connected to the middle of the upper surface of the fixing plate, and a pressing plate is fixedly connected to the bottom end of the telescopic rod. A first spring is fixedly connected to the lower surface of the pressing plate around the telescopic rod.

[0008] Preferably, an anti-slip pad is fixedly connected to the upper surface of the extrusion plate. The anti-slip pad is made of silicone. The anti-slip pad increases the friction of the limiting plate against the welding wire ring when it is pushed, making the push more stable.

[0009] Preferably, the support assembly includes a base plate, the edge of the upper surface of the base plate is fixedly connected to the bottom end of the protective assembly, and support plates are fixedly connected to both sides of the upper surface of the base plate. Fixing bolts are threadedly connected to both sides of the upper surface of the support plates. A limiting plate is threadedly connected to the outer surface of the fixing bolt, and a connecting rod is provided on the lower surface of the limiting plate. The connecting rod is inserted through the coil assembly, then overlapped into the groove in the middle of the upper surface of the two support plates. The limiting plate is then inserted into the through groove and fixed with the fixing bolt, thereby facilitating the erection of the coil assembly and conveniently releasing the wire.

[0010] Preferably, the protective assembly includes a support rod, the bottom end of which is fixedly connected to the edge of the upper surface of the base plate, and the top end of which is fixedly connected to a limiting ring. A second spring is fixedly connected to the inner top wall of the limiting ring, and a gravity hammer is fixedly connected to the bottom end of the second spring. A limiting bolt is fixedly connected to the upper part of the outer surface of the gravity hammer. The welding wire passes through the limiting ring, which is below the gravity hammer. During use, the welding wire is taut and generates thrust, pushing the gravity hammer upward and compressing the second spring, leaving space below the gravity hammer so as not to affect wire release. After the welding wire is cut, the welding wire falls, and the second spring pushes the gravity hammer down quickly to compress the welding wire, preventing the welding wire from being instantly retracted, which could cause the coil to burst, making the coil messy and affecting the next use.

[0011] Preferably, the wire coil assembly includes an inner ring, the inner ring being rotatably connected to the outer surface of the connecting rod, connecting plates being fixedly connected to both sides of the outer surface of the inner ring, an outer ring being fixedly connected to one side of the connecting plate, and limiting discs being fixedly connected to both ends of the outer ring; the inner ring facilitates the passage of the connecting rod, the connecting plates connect the inner ring and the outer ring, the outer ring facilitates the winding of the welding wire, and the limiting discs facilitate the limiting of the wound welding wire coil to prevent it from loosening to both sides.

[0012] Preferably, a through groove is provided on one side of the support plate, and the through groove is adapted to the limiting plate; the through groove facilitates the insertion of the limiting plate, thereby limiting and fixing the connecting rod.

[0013] Preferably, a groove is provided in the middle of the upper surface of the support plate, and the groove is adapted to the connecting rod; the groove facilitates the placement of the connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] I. This utility model uses a fastening assembly to fix the fixing plate to the base plate below the wire reel assembly with bolts. The first spring pushes and limits the plate to push and squeeze the welding wire ring wound on the outer ring. The telescopic rod prevents the first spring from deforming to the left and right, which facilitates the increase of resistance between the support assembly and the wire reel assembly, and prevents the welding wire from loosening during use, thereby affecting the welding quality and causing welding wire waste.

[0016] II. This utility model, through the protective components, allows the welding wire to pass through the limiting ring, which is below the gravity hammer. During use, the welding wire is taut and generates thrust, pushing the gravity hammer upward and compressing the second spring, leaving space below the gravity hammer so as not to affect wire release. After the welding wire is cut, the welding wire falls, and the second spring pushes the gravity hammer down quickly to compress and solidify the welding wire, preventing the welding wire from being instantly retracted, which could cause the coil to burst, making the coil messy and affecting the next use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-5 The figure shows a wire reel that can tighten welding wire, including a support assembly 1, a fastening assembly 2 fixedly connected to the middle of the upper surface of the support assembly 1, a protective assembly 3 fixedly connected to the edge of the upper surface of the support assembly 1, and a wire reel assembly 4 rotatably connected to the outer surface of the support assembly 1.

[0026] The fastening assembly 2 includes a fixing plate 201. The lower surface of the fixing plate 201 is threadedly connected to the middle of the upper surface of the bracket assembly 1 by bolts 202. A telescopic rod 203 is fixedly connected to the middle of the upper surface of the fixing plate 201. A pressing plate 204 is fixedly connected to the bottom end of the telescopic rod 203. A first spring 205 is fixedly connected to the lower surface of the pressing plate 204 located around the telescopic rod 203.

[0027] In this implementation scheme: the fixing plate 201 is fixed to the base plate 101 below the wire reel assembly 4 using bolts 202. The first spring 205 pushes and squeezes the welding wire ring wound on the outer ring 403 by pushing and squeezing the limiting plate 104. The telescopic rod 203 prevents the first spring 205 from deforming left and right, which facilitates the increase of resistance between the bracket assembly 1 and the wire reel assembly 4, and prevents the welding wire from loosening during use, thereby affecting the welding quality and causing welding wire waste.

[0028] Please see Figure 1 and Figure 3 As shown in the figure, an anti-slip pad 5 is fixedly connected to the upper surface of the extrusion plate 204. The anti-slip pad 5 is made of silicone.

[0029] In this embodiment: the anti-slip pad 5 increases the friction of the limiting plate 104 when pushing the welding wire ring, making the pushing more stable.

[0030] Working principle: First, use bolts 202 to fix the fixing plate 201 to the base plate 101 below the coil assembly 4. Next, insert the connecting rod 105 through the coil assembly 4, and then overlap the connecting rod 105 into the groove opened in the middle of the upper surface of the two side support plates 102. Then, insert the limiting plate 104 into the through groove and fix it with the fixing bolt 103, thereby setting up the coil assembly 4. Next, the first spring 205 pushes the limiting plate 104 to wrap around the outer ring 403. The welding wire coil is pushed and squeezed, and the telescopic rod 203 prevents the first spring 205 from deforming left and right. Finally, the welding wire passes through the limiting ring 302, which is below the gravity hammer 304. During use, the welding wire is taut and generates thrust, pushing the gravity hammer 304 upward and squeezing the second spring 303, leaving space below the gravity hammer 304 so as not to affect the wire release. After the welding wire is cut, the welding wire falls, and the second spring 303 pushes the gravity hammer 304 down quickly to compress the welding wire.

Support plates 102 are fixedly connected to both sides of the upper surface of the base plate 101. Fixing bolts 103 are threadedly connected to both sides of the upper surface of the support plate 102. Limiting plates 104 are threadedly connected to the outer surface of the fixing bolts 103. A connecting rod 105 is provided on the lower surface of the limiting plate 104.

[0033] In this embodiment: the connecting rod 105 is inserted through the coil assembly 4, and then the connecting rod 105 is overlapped into the groove opened in the middle of the upper surface of the two side support plates 102. Then the limiting plate 104 is inserted into the through groove and fixed with the fixing bolt 103, so as to facilitate the erection of the coil assembly 4 and facilitate the laying of the wire.

[0034] Please see Figure 1 and Figure 4 The protective component 3 shown in the figure includes a support rod 301. The bottom end of the support rod 301 is fixedly connected to the edge of the upper surface of the base plate 101. The top end of the support rod 301 is fixedly connected to a limit ring 302. A second spring 303 is fixedly connected to the inner top wall of the limit ring 302. A gravity hammer 304 is fixedly connected to the bottom end of the second spring 303. A limit bolt 305 is fixedly connected to the upper part of the outer surface of the gravity hammer 304.

[0035] In this embodiment: the welding wire passes through the limiting ring 302, which is below the gravity hammer 304. During use, the welding wire is taut and generates thrust, pushing the gravity hammer 304 upward and compressing the second spring 303, leaving space below the gravity hammer 304 so as not to affect wire release. After the welding wire is cut, the welding wire falls, and the second spring 303 pushes the gravity hammer 304 down quickly to compress and solidify the welding wire, preventing the welding wire from being instantly retracted, which could cause the coil to burst, making the coil messy and affecting the next use.

[0036] Please see Figure 1 and Figure 5 The diagram shows that the coil assembly 4 includes an inner ring 401, which is rotatably connected to the outer surface of the connecting rod 105. Both sides of the outer surface of the inner ring 401 are fixedly connected to a connecting plate 402. One side of the connecting plate 402 is fixedly connected to an outer ring 403. Both ends of the outer ring 403 are fixedly connected to a limit plate 404.

[0037] In this embodiment: the inner ring 401 facilitates the passage of the connecting rod 105, the connecting plate 402 connects the inner ring 401 and the outer ring 403, the outer ring 403 facilitates the winding of the welding wire, and the limiting plate 404 facilitates the limiting of the wound welding wire ring to prevent it from loosening to both sides.
