[0033] In order to solve at least one technical problem mentioned in the background technology, the utility model proposes a welding wire feeder which can perform forced air cooling on the wire feeder control panel, has a small size and light weight, is easy to move and does not tip over.

[0034] like Figure 1 As shown, a wire feeder for welding comprises a frame, a box body is arranged on the frame, and a wire feeding mechanism, a wire feeder control panel and a display panel are arranged in the box body; a display panel accommodating box is arranged on the front side of the box body, and the display panel is arranged in the display panel accommodating box; an inner vertical plate and an insulating vertical plate are arranged in the middle part of the box body, and the inner vertical plate and the insulating vertical plate divide the box body into a left box body and a right box body, the wire feeding wheel side of the wire feeding mechanism is arranged in the left box body, and the motor side of the wire feeding mechanism is arranged in the right box body; the wire feeder control panel is arranged in the right box body, and an air inlet and an air outlet are arranged on two outer sides of the right box body, and a fan is arranged at one air outlet.

[0035] The utility model divides the box of the wire feeder into a plurality of independent and sealed chambers, and arranges the wire feeding mechanism, the wire feeder control panel and the display panel respectively, and reduces the volume of the whole machine by rationally arranging each space. An air inlet and outlet and a fan are arranged in the chamber of the wire feeder control panel, and the wire feeder control panel is cooled by forced air cooling while meeting the dust and interference resistance of the wire feeder control panel, thereby ensuring the effectiveness of the control, extending the service life of the wire feeder, and improving the welding quality.

[0036] Embodiment 1

[0037] In one or more embodiments, a welding wire feeder is disclosed, referring to Figure 1-Figure 5 , including a frame 10, the frame 10 is welded by a bottom plate 101, a wire reel box fixing frame 102, a front panel 103, a rear panel 104, an inner side vertical plate 105, a cable fixing seat bracket 106, a welding gun bracket 107 and a handle 108, and has high overall strength. A wire reel box 20 and a wire feeding mechanism 30 are installed on the frame 10, the wire reel box 20 is fixed on the wire reel box fixing frame 102 through a wire reel shaft, and the wire feeding mechanism 30 is fixed on the bottom plate 101, and is located in a box body composed of a front panel 103, a rear panel 104, a left side plate 40, a right side plate 50 and a top cover 60; an insulating vertical plate 70 is attached to one side of the inner side vertical plate 105, and the box body is divided into a left box body and a right box body by the inner side vertical plate 105 and the insulating vertical plate 70, and the wire feeding wheel side of the wire feeding mechanism 30 is located in the left box body, and the motor side is located in the right box body.

[0038] The bottom plate is provided with a plurality of weight-reducing holes, the box body is provided on the front side of the bottom plate, a wire reel box fixing frame is provided on the rear side of the bottom plate, a wire reel box is mounted on the wire reel box fixing frame, and a transparent observation window is provided on the wire reel box.

[0039] like Figure 1 , Figure 2 As shown, the bottom plate 101 is provided with N weight-reducing holes 1011, which are used to reduce the weight of the whole machine while meeting the overall strength. The wire reel box 20 is provided with a transparent observation window 201, which is convenient for the user to observe the use of the welding wire at any time without opening the wire reel box 20.

[0040] A notch is provided on the rear side of the left box body, and the notch has a set width. A wire guide rod is provided at the wire feeding end of the wire feeding mechanism, and the wire guide rod passes through the notch and extends to the inside of the wire outlet of the wire reel box.

[0041] like Figure 3As shown, a square notch 1041 is provided on the rear side of the left box body, and a wire guide rod 301 is provided at the wire feeding end of the wire feeding mechanism 30. The wire guide rod 301 extends to the inside of the wire outlet of the wire reel box 20 after passing through the square notch 1041. Since the welding wire is wound on the welding wire reel, the welding wire will be offset in the width direction of the welding wire reel during welding, which causes the angle at which the welding wire enters the wire guide rod 301 to change at any time, thereby causing the wire guide rod 301 to swing left and right. When the width of the square notch 1041 is too narrow and the swing amplitude of the wire guide rod 301 is too large, it is easy for the wire guide rod 301 to collide and rub against the square notch 1041. Therefore, the square notch 1041 is designed to have a sufficient width to ensure that during the wire feeding process, the wire guide rod 301 will not rub against the square notch 1041, thereby affecting welding.

[0042] The box body includes a rear panel and a top cover, the top cover is an inverted U-shape, a control panel bracket is arranged on the upper part of the right box body, and the wire feeder control panel is installed in a closed space composed of the control panel bracket, the rear panel, the inner vertical panel and the top cover.

[0043] like Figure 2 , Figure 4 As shown, a control panel bracket 80 is provided on the upper part of the right box body. The control panel bracket 80, the rear panel 104, the inner side vertical plate 105 and the top cover 60 form a closed space. The wire feeder control panel 90 is installed and fixed in this closed space, which can prevent dust and isolate external interference. Sealing strips are provided at the contact surfaces of the control panel bracket 80, the rear panel 104, the inner side vertical plate 105 and the top cover 60 to ensure the sealing of the closed space. The control panel bracket 80 is provided with a first inlet and outlet hole 801 and a dustproof rubber ring is installed to ensure the sealing of the closed space.

[0044] The top cover 60 is fixed on the frame 10 through a connector, an air inlet 601 is provided on one side and a fan and a protective device are installed, and an air outlet 1042 is provided on the rear panel 104 and a protective device is installed, which can meet the heat dissipation requirements of the wire feeder control board 90 while preventing dust. Of course, it can be understood that the positions of the air inlet and the air outlet can be specifically arranged according to actual conditions.

[0045] The box body includes a left side plate, the top of the left side plate is rotatably connected to the top cover by a damping hinge, and the connecting gap between the left side plate and the top cover is located on the left side of the box body, a lock is provided on the bottom side of the left side plate, a notch is provided on the bottom plate, the lock of the left side plate can be snapped into the notch of the bottom plate, and a right side plate is provided on the right side of the box body, and the connecting gap between the right side plate and the top cover is located on the right side of the box body.

[0046] like Figure 1 , Figure 3As shown, the left side plate 40 and the top cover 60 adopt a split design, which is rotatably connected by a damping hinge. When flipped, they can hover at any angle, which is convenient for users to change wires and prevent safety accidents. A lock is provided on the left side plate 40. When the left side plate 40 is closed, the lock is locked with the notch on the bottom plate 101 to prevent dust and metal dust from entering the left box. Compared with the traditional wire feeder that sets the connection gap on the top surface of the box, the connection gap between the left side plate 40 and the top cover 60 in this embodiment is set on the left side of the box, avoiding the travel route of the welding wire, and preventing dust and metal dust from falling on the welding wire and the wire feeding mechanism 30 at the gap when flipped, thereby affecting the welding quality.

[0047] The right side plate 50 is fixed to the frame 10 through a connector. The right side plate 50 and the top cover 60 are split, which is convenient for disassembling and assembling the wire feeder cable, and at the same time ensures that the enclosed space for installing the wire feeder control board 90 will not be affected by the external environment. Compared with the traditional wire feeder in which the connection gap is set on the top surface of the box, the connection gap between the right side plate 50 and the top cover 60 in this embodiment is set on the right side of the box, avoiding the enclosed space for installing the wire feeder control board 90, and preventing dust and metal dust from falling on the wire feeder control board 90 when the gap is turned over, thereby affecting the control.

[0048] The left side plate 40, the right side plate 50 and the top cover 60 are formed by bending aluminum plates, which reduces the weight of the whole machine while meeting the structural strength. In addition, the aluminum plates are used to isolate the adsorption of magnetic metal dust at the welding site.

[0049] like Figure 4 , Figure 5 As shown, a display panel accommodating box 1031 is provided inside the front panel 103. The display panel accommodating box 1031, the front panel 103 and the display panel bracket 100 form a closed space, and the display panel 110 is installed and fixed in the closed space. The display panel accommodating box 1031 adopts a stepped structure to avoid high parts on the display panel 110. The display panel accommodating box 1031 is provided with a second inlet and outlet hole 10311 and a dustproof rubber ring is installed to ensure the sealing of the closed space.

[0050] A plastic front panel 120 is installed outside the front panel 103, which can not only improve the appearance, but also close the gaps around the front panel 103 to prevent external dust and metal dust from entering the box.

[0051] The frame is also provided with a cable fixing seat bracket and a U-shaped frame, the cable fixing seat bracket is provided with a plurality of slots, the cable fixing seat bracket is provided with a cable fixing seat, and the wire feeder cable and the wire feeder are in a dead interface connection form.

[0052] like Figure 4 , Figure 5As shown, a cable fixing seat 130 is provided on the cable fixing seat bracket 106, which is used to connect the external wire feeder cable and fix the cable to prevent it from loosening. A plurality of slots 1061 are provided on the cable fixing seat bracket 106, and the cables can be internally bundled and fixed with cable ties. A U-shaped frame 140 is installed on the frame 10 for externally fixing the cable. The wire feeder cable and the wire feeder are connected in a dead interface form, and no intermediate conversion joint is used, which can reduce the weight of the whole machine, avoid failure of the transfer, and reduce costs.

[0053] The welding gun bracket 107 is formed by bending steel wire and welded to the handle 108, which is convenient for placing the welding gun, reducing the weight of the whole machine and reducing the width of the whole machine, which is convenient for packaging and transportation of the whole machine. The handle 108 is formed by bending a round tube, one end of which is welded to the bottom plate 101 and the wire reel box fixing frame 102, and the other end is covered with non-slip rubber, which not only improves the user's hand feeling, but also facilitates lifting and moving.

[0054] like Figure 5 As shown, a shaft sleeve 150 is installed in the middle of the base plate 101. The shaft sleeve and the base plate have an interference fit, and the shaft sleeve is directly hammered into the round tube on the base plate, and there is no relative rotation between the two; the shaft sleeve 150 is made of insulating material and is used for insulation between the wire feeder and the welding trolley. The wire feeder is placed on the all-in-one welding trolley through this shaft sleeve 150, and the entire wire feeder can be rotated 360° in the horizontal direction, which is convenient for multi-angle welding, so that the welding wire is always fed in a suitable path to avoid wire jamming. There is no need to move the wire feeder within the reach of the welding gun. If it needs to be moved, it can be achieved by using the welding trolley.

[0055] Furthermore, rubber feet are installed on the bottom plate 101 for insulation and shock absorption. When the wire feeder rotates on the welding trolley through the shaft sleeve, the bottom surface of the rubber foot 160 is higher than the crossbeam and handle on the welding trolley, and will not collide with the welding trolley, and can rotate 360 ​​degrees in the horizontal direction normally.

[0056] Embodiment 2

[0057] The welding wire feeder of this embodiment has the same features as those of the first embodiment except that the machine foot adopts the roller assembly 170.

[0058] Reference Figure 6 The front part of the roller assembly 170 is a universal wheel assembly, and the rear part is a directional wheel assembly, which facilitates the movement of the wire feeder. The horizontal span of the roller assembly 170 is wider than the maximum width of the wire feeder, and the directional wheel assembly at the rear is located at the lower end or rear end of the wire reel box axis. The span of the universal wheel assembly at the front and the directional wheel assembly at the rear is large to ensure stability during movement and prevent the wire feeder from tipping over.

[0059] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
