Abstract
The utility model discloses an arc strike plate pair made of copper alloy and provided with an elastic connecting piece. Arc strike plates are made of the copper alloy so that mixed melting, at welding joints, of the arc strike plates and steel to be welded is avoided, and therefore the arc strike plates made of the copper alloy can be removed easily in a not damaged mode after welding, welding efficiency is improved and repeated utilization of the arc strike plates is realized. Further, the unique shapes of the arc strike plates bring convenience to installation of the arc strike plates aligned to and on parts, of the steel, to be welded, and therefore troubles brought by utilization of specific welding devices and jigs are omitted. Moreover, the elastic connecting piece can be used to connect the arc strike plates into a pair in a rotating mode so as to further bring convenience to the installation and location.
Description
Technical field
The utility model relates to a kind of arc welding accessory, especially a kind of copper alloy run-on tab processed with Flexible Connector pair.
Background technology
In the electric arc welding processes such as steel fillet welding, because unstable at the stem of sealing wire and afterbody weldingvoltage, electric current, usually there is the mass defect of welding.In order to guarantee to weld the quality of rear steel parts, must be with the both ends excision of weld seam, this causes the whole pattern of soldered steel to destroy and causes material to waste in a large number.For this reason, common way is at steel position corresponding to the stem of sealing wire and afterbody run-on tab to be installed, and makes weld defect stay on the run-on tab and after welding is finished run-on tab is removed.The run-on tab that uses now generally is to make with the material of the identical material of welded steel, and since welding to be removed after finishing, carry out the fixing of run-on tab so adopt the mode of tack welding, yet this not only will use specific welder and stationary fixture, operation very difficult, even if the tack welding that carry out in order to remove convenient, the intensity of its welding is also very high, causes the also time and effort consuming of work of removing run-on tab after the welding.Simultaneously, such run-on tab can not Reusability, can only again reclaim as waste material.
Therefore, develop a kind of specific weld device and anchor clamps of not needing, can be fast and install easily and remove, the run-on tab that simultaneously can iterative cycles uses, for improving arc welding efficient, welding performance and saving welding cost, have actual and important value.
Summary of the invention
The purpose of this utility model namely be to provide a kind of installation and remove convenient, and the run-on tab processed of the copper alloy with Flexible Connector that can Reusability pair.
The technical scheme that the utility model adopts is as follows: a kind of copper alloy run-on tab processed with Flexible Connector pair, and it comprises a pair of copper alloy run-on tab processed; Wherein, each described copper alloy run-on tab processed obtains by the processing of copper alloy cuboid ingot bar; In the rectangle of the bottom surface of described cuboid, take a summit of its bottom surface as the center of circle, half of bottom surface width edge length is that long limit and the broadside of the half radial shape bottom surface that becomes described summit drawn arc, form the first paragraph circular arc, the intersection point of the broadside of described first paragraph circular arc and described bottom surface is A, with the intersection point on the long limit of described bottom surface be B; In the side at B point place, become angle at 45 ° from B point injection line m and m with described bottom surface, from the A point draw the ray n that is parallel to side, B point place and n also with angle at 45 °, described bottom surface; And two the end face of described ray m, n and described cuboid meets at respectively C, D 2 points; Form the second segment circular arc that has identical radian measure with described first paragraph circular arc at C, D point-to-point transmission; With described first paragraph circular arc and the second segment circular arc formation arc-shaped transitional surface that is as the criterion; The part of arc-shaped transitional surface inboard is removed from the cuboid ingot bar, and had an axis hole in the relative side of side, B point place, namely obtain the shape of described copper alloy run-on tab processed; Described copper alloy run-on tab processed is to also comprising a Flexible Connector, the two ends of Flexible Connector are inserted respectively in the axis hole of described a pair of copper alloy run-on tab processed and with described a pair of copper alloy run-on tab processed and are connected rotationally, thereby form described copper alloy run-on tab processed with Flexible Connector pair.
The beneficial effects of the utility model are, use copper alloy as the material of run-on tab, avoided run-on tab at commissure and welded steel consolute, thereby can get and without breakage ground copper alloy run-on tab processed be removed easily after welding is finished, improved welding efficiency and realized recycling of run-on tab; In addition, the shape of this copper alloy run-on tab uniqueness processed is convenient to it in aligning installation at welded steel position, saves the trouble of using specific weld device and anchor clamps; Adopt in addition Flexible Connector with run-on tab rotating be connected to form a pair of, the more convenient installation and the location.

The specific embodiment
Below in conjunction with accompanying drawing 1-3, describe the copper alloy run-on tab processed with Flexible Connector of the present utility model pair in detail, as shown in Figure 1, it comprises a pair of copper alloy run-on tab processed; Wherein, each described copper alloy run-on tab processed obtains by the processing of copper alloy cuboid ingot bar; In the rectangle of the bottom surface of described cuboid, take a summit of its bottom surface as the center of circle, half of bottom surface width edge length is that long limit and the broadside of the half radial shape bottom surface that becomes described summit drawn arc, form first paragraph circular arc 1, described first paragraph circular arc 1 is A with the intersection point of the broadside of described bottom surface, with the intersection point on the long limit of described bottom surface be B; In the side at B point place, become angle at 45 ° from B point injection line m and m with described bottom surface, from the A point draw the ray n that is parallel to side, B point place and n also with angle at 45 °, described bottom surface; And two the end face of described ray m, n and described cuboid meets at respectively C, D 2 points; Form the second segment circular arc 2 that has identical radian measure with described first paragraph circular arc 1 at C, D point-to-point transmission; Be as the criterion with described first paragraph circular arc 1 and second segment circular arc 2 and form arc-shaped transitional surface 3; The part of arc-shaped transitional surface 3 inboards is removed from the cuboid ingot bar, and had an axis hole 7 in the relative side of side, B point place, namely obtain the shape of described copper alloy run-on tab processed; As shown in Figure 2, described copper alloy run-on tab processed is to also comprising a Flexible Connector 8, the two ends of Flexible Connector 8 are inserted respectively in the axis hole 7 of described a pair of copper alloy run-on tab processed and with described a pair of copper alloy run-on tab processed and are connected rotationally, thereby form described copper alloy run-on tab processed with Flexible Connector pair.
Before the welding, as shown in Figure 3, the face that broadside and the flash of one side of the first soldered steel 4 and copper alloy run-on tab processed the formed placement that aligns, and end one side of the second soldered steel 5 is aimed at placement with described B point, thus the stem 6 of weld seam is formed in the transition face 3.
