Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically to a welding conductive nozzle bending device. Background Technology

[0002] Small-sized cast steel wedge gate valves have separate valve bodies and seats, requiring welding to connect them. Due to the limited diameter of the valve body passage, the gas-shielded welding torch can only move horizontally. Therefore, the contact tip and protective sleeve at the front end must be bent to ensure the effectiveness of the weld. Manual welding does not require specific torch placement; the contact tip is bent manually with pliers or by hammering, a crude and simple method resulting in poor dimensional consistency.

[0003] At present, most welding is automated, which requires high precision in the position of the welding torch. If the bending degree of the contact tip is different, the position of the welding torch will deviate significantly after the contact tip is replaced. The position of the welding torch needs to be recalibrated, which makes the operation more cumbersome and is not conducive to the welding process. Utility Model Content

[0004] In view of this, the present invention provides a welding conductive tip bending device to solve the problem of different bending degrees of conductive tips.

[0005] This utility model provides a welding conductive tip bending device, comprising: The fastener has a first arcuate surface, and the first arcuate surface has a first guide groove extending along its arcuate direction; A rotating component is rotatably connected to the fixed component. A pressure component is rotatably connected to the rotating component. The pressure component has a second arc surface opposite to the first arc surface. The second arc surface has a second guide groove extending along its arc direction. The cavity formed by the second guide groove and the first guide groove is suitable for accommodating the bending section of the conductive tip.

[0006] This invention involves placing the section of the conductive tip to be bent into the cavity formed by the first and second guide grooves. Rotating the rotating component causes the pressure component to rotate, bending the section of the conductive tip until it aligns with the first guide groove. Using this device, the bending degree of the conductive tip is consistent, the welding torch position changes minimally after replacing the conductive tip, and operation is convenient.

[0007] Optionally, the fastener has at least two detachable parts, wherein the first part is formed with the first arcuate surface, and the second part has a through hole facing one end of the first guide groove.

[0008] In the above scheme, the fixing component is divided into two parts, which facilitates the insertion of the conductive nozzle.

[0009] Optionally, the perforation has an annular boss for abutting against the root flange of the conductive tip.

[0010] In the above solution, the conductive tip is prevented from sliding out of the perforation, thus preventing the conductive tip from being bent.

[0011] Optionally, the first part and the second part are connected by fasteners.

[0012] In the above solution, the first and second parts are detachably connected and fixed with fasteners, making it more convenient to use.

[0013] Optionally, the fastener is an internal hex screw.

[0014] Of the above options, the internal hex screw is suitable for more occasions, especially in narrow spaces, as it is easy to use and can withstand greater torque and load.

[0015] Optionally, the first portion has an outer right-angled side, and the second portion has an inner right-angled side, wherein the inner right-angled side is attached to the outer right-angled side.

[0016] In the above scheme, the first and second parts are processed simultaneously, and then cut later, which facilitates operation.

[0017] Optionally, the second portion has a first segment and a second segment that are perpendicular to each other, the first segment having a through hole for a fastener to pass through, and the second segment having the through hole.

[0018] In the above scheme, the through hole is used to pass through the fastener and the first part for connection, and the perforation is used to place the conductive nozzle to prevent the conductive nozzle from moving when bending.

[0019] Optionally, the central angle between the first arcuate surface and the second arcuate surface is ≥90 degrees.

[0020] The above solution prevents the bottom of the conductive tip from being bent out of reach.

[0021] Optionally, the rotating member has a frame portion and a handle portion fixedly connected to the frame portion. The frame portion is rotatably connected to the fixing member via a first rotating shaft, and the frame portion is rotatably connected to the pressure member via a second rotating shaft.

[0022] The above design facilitates the operation of rotating components and prevents misalignment of fixed and pressure components.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 As shown, this is a specific implementation of the welding conductive tip bending device provided in this embodiment, which includes: a fixing member 1 and a rotating member 3.

[0030] like Figure 1 , Figure 4 As shown, the fastener 1 has a first arc-shaped surface, and the first arc-shaped surface has a first guide groove 2 extending along its arc direction; like Figure 1 , Figure 5 , Figure 6 As shown, the rotating component 3 is rotatably connected to the fixed component 1, and a pressure component 4 is rotatably connected to the rotating component 3. The pressure component 4 has a second arc-shaped surface opposite to the first arc-shaped surface. The second arc-shaped surface has a second guide groove 5 extending along its arc direction. The cavity 6 formed by the second guide groove 5 and the first guide groove 2 is suitable for accommodating the bending section of the conductive tip.

[0031] In this embodiment, the section of the conductive tip to be bent is placed into the cavity 6 formed by the first guide groove 2 and the second guide groove 5. Rotating the rotating component 3 causes the pressure component 4 to rotate, bending the section of the conductive tip until it fits into the first guide groove 2. Using this device, the bending degree of the conductive tip is consistent, the position of the welding torch changes minimally after changing the conductive tip, and operation is convenient.

[0032] like Figure 2 , Figure 4 As shown, the fixing member 1 has at least two detachable parts, wherein the first part 7 is formed with the first arc-shaped surface, and the second part 8 has a through hole 9 directly opposite one end of the first guide groove 2. This arrangement divides the fixing member 1 into two parts, facilitating the insertion of the conductive nozzle.

[0033] Of course, the above description is not limiting. In some alternative embodiments, the fastener 1 can be a single unit.

[0034] like Figure 3 , Figure 7 , Figure 8 As shown, the perforation 9 has an annular boss 10 for abutting against the root flange of the conductive tip. This design prevents the conductive tip from sliding out of the perforation 9 and makes the conductive tip impossible to bend.

[0035] Of course, the above description is not limiting, and in some alternative embodiments, the annular boss 10 may be omitted.

[0036] like Figure 3 , Figure 4As shown, the first part 7 and the second part 8 are connected by fastener 11. This configuration allows the first part 7 and the second part 8 to be detachably connected and secured by fastener 11, making them more convenient to use.

[0037] Of course, the above description is not limiting. In some alternative embodiments, the fastener 11 can be replaced with a snap-fit ​​structure.

[0038] like Figure 3 , Figure 4 As shown, the fastener 11 is a hex socket head cap screw. This design makes the hex socket head cap screw suitable for more applications, especially in confined spaces, easy to use, and able to withstand greater torque and load.

[0039] Of course, the above description is not limiting. In some alternative embodiments, the hex socket screw can be replaced with a cross screw.

[0040] like Figure 2 , Figure 3 As shown, the first part 7 has an outer right-angled side, and the second part 8 has an inner right-angled side, with the inner right-angled side fitting against the outer right-angled side. This configuration allows for simultaneous processing of the first part 7 and the second part 8, facilitating subsequent cutting and operation.

[0041] Of course, the above description is not limiting; in some alternative embodiments, the inner right-angled side and the outer right-angled side may be separated.

[0042] like Figure 3 , Figure 8 As shown, the second part 8 has a first segment 12 and a second segment 13 that are perpendicular to each other. The first segment 12 has a through hole 14 for the fastener 11 to pass through, and the second segment 13 has the through hole 9. In this configuration, the through hole 14 is used to connect the fastener 11 and the first part 7, and the through hole 9 is used to place the conductive tip and prevent the conductive tip from moving when bent.

[0043] Of course, the above description is not limiting. In some alternative embodiments, the through hole 14 may be omitted, and the first part 7 and the second part 8 may be snapped together.

[0044] like Figure 3 As shown, the central angle between the first arc-shaped surface and the second arc-shaped surface is ≥90 degrees. This design prevents the bottom of the conductive tip from being inaccessible.

[0045] Of course, the above description is not limiting. In some alternative embodiments, the central angle between the first arcuate surface and the second arcuate surface is only 90 degrees.

[0046] like Figure 2As shown, the rotating component 3 has a frame portion 15 and a handle portion 16 fixedly connected to the frame portion 15. The frame portion 15 is rotatably connected to the fixing component 1 via a first rotating shaft 17, and the frame portion 15 is rotatably connected to the pressure component 4 via a second rotating shaft 18. This arrangement facilitates the operation of rotating component 3 and prevents the fixing component 1 and pressure component 4 from shifting.

[0047] Of course, the above description is not limiting, and in some alternative embodiments, the handle portion 16 may be omitted.

[0048] like Figure 3 As shown, the distance between the first rotating shaft 17 and the second rotating shaft 18 is d, the radius of the first arc-shaped surface on the fixing member 1 is r1, and the radius of the second arc-shaped surface on the pressure member 4 is r2, where d ≥ r1 + r2. This arrangement prevents the pressure member 4 from being unable to rotate, thus preventing the conductive nozzle from bending.

[0049] Of course, the above description is not limiting. In some alternative embodiments, the distance between the first rotating shaft 17 and the second rotating shaft 18 is only equal to the sum of the radius of the first arc surface and the radius of the second arc surface.

[0050] Instructions for use: Insert the straight conductive tip into the perforation 9, so that the root flange of the conductive tip abuts against the annular boss 10. Tighten the fastener 11 so that the section of the conductive tip to be bent enters the cavity 6 formed by the first guide groove 2 and the second guide groove 5. Rotate the handle 16 so that the frame 15 rotates around the first rotating shaft 17 and the pressure member 4 rotates around the second rotating shaft 18. This makes the first guide groove 2 of the fixing member 1 fit with the bent part of the conductive tip until the section of the conductive tip to be bent is completely fitted with the first guide groove 2. Loosen the fastener 11, move the second part 8, and take out the bent conductive tip.

[0051] Using this device, the bending degree of the contact tip is the same, and the position of the welding gun changes little after changing the contact tip, making it easy to operate.

[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
