Description

Technical Field

[0001] The utility model relates to a cutting tool for cutting welding burrs after flash welding of an electric welding anchor chain, in particular to a split type cutting tool for cutting welding burrs of an anchor chain ring, belonging to the technical field of special tools for manufacturing electric welding anchor chains. Background Art

[0002] Anchor chains are used for mooring ships and offshore equipment, and are crucial components for the safety of both ships and offshore equipment operating in shallow or deep waters. The manufacturing process for anchor chain links is as follows: bar heating—horizontal bending—flash welding—weld burr removal—and press-fitting into the crosspiece. After flash welding, a loose, hot, circular weld burr forms along the weld surface in the middle of one longitudinal side of the anchor chain link. The next step is to remove this burr to improve the surface quality of the anchor chain weld and prevent it from being pressed into the crosspiece during the press-fitting process, which could affect the mechanical properties of the anchor chain link.

[0003] The existing bayonet remover for removing burrs from anchor chain ring welding is an integral structure. The cutting edge of the bayonet remover is greatly worn and needs to be sharpened or replaced frequently. It is also very easy to be damaged. The entire tool must be replaced every thousand rings or so. Not only is the tool life short, the cost is high, the operation efficiency is low, but also the disassembly and assembly is difficult and cumbersome. Utility Model Content

[0004] The utility model aims to provide a split anchor chain ring weld bayonet remover which has the advantages of simple structure, low cost and long service life.

[0005] The utility model is achieved through the following technical solutions:

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, the utility model includes a first bayonet remover 1 and a second bayonet remover 2, whose cutting edges are arranged opposite and parallel to each other. The first bayonet remover 1 is longer than the second bayonet remover 2. The first bayonet remover 1 and the second bayonet remover 2 are both made of 45 steel with a hardness of HRC 20-30. The left end surfaces of the first bayonet remover 1 and the second bayonet remover 2 are respectively fixed flush on the bayonet remover mounting base 3, and the right ends of the first bayonet remover 1 and the second bayonet remover 2 respectively extend out of an L-shaped knife base. The first and second bayonet removal blade heads 11 and 21 are respectively fixed to the L-shaped blade holders of the first and second bayonet removal blades 1 and 2. The inner side surface of the first bayonet removal blade head 11 is provided with a first cutting edge 111 and a second cutting edge 112, both facing the outer ends of the L-shaped blade holder. The inner side surface of the second bayonet removal blade head 21 is provided with a third cutting edge 211 facing the outer end of the L-shaped blade holder and a fourth cutting edge 212 facing the inner end of the L-shaped blade holder. The first and third cutting edges 111 and 211 are horizontally staggered to prevent the two cutting edges from simultaneously cutting weld burrs and reduce cutting force. The distance L between the cutting edge plane H of the first bayonet removal blade 1 and the cutting edge plane E of the second bayonet removal blade 2 is equal to the cross-sectional diameter D of the anchor chain ring body 4. The cutting edges of the second and fourth cutting edges 112 and 212, which are opposite to each other, are centrally symmetrical about the cross-sectional axis of the anchor chain ring body 4. The first bayonet removal blade head and the second bayonet removal blade head are both made of H13 steel with a hardness of HRC56-58.

[0021] The first bayonet removal blade head 11 has a dovetail groove 113 at its bottom, and a dovetail stand 114 is provided inside the L-shaped blade holder of the first bayonet removal blade 1. The first bayonet removal blade head 11 is mounted on the dovetail stand 114 inside the L-shaped blade holder of the first bayonet removal blade 1 via the dovetail groove 113. The second bayonet removal blade head 21 has a dovetail groove 213 at its top, and a dovetail stand 214 is provided inside the L-shaped blade holder of the second bayonet removal blade 2. The second bayonet removal blade head 21 is mounted on the dovetail stand 214 inside the L-shaped blade holder of the second bayonet removal blade 2 via the dovetail groove 213. The thickness of the first bayonet removal blade head 11 and the second bayonet removal blade head 21 are the same as the thickness of the corresponding L-shaped blade holder.

[0022] The first positioning blocks 115 at the right bottom and left side of the first bayonet removal blade head 11 are respectively embedded in the first positioning grooves 116 at the corresponding positions on the L-shaped blade holder of the first bayonet removal blade 1. The second positioning blocks 215 on both sides of the second bayonet removal blade 2 are respectively embedded in the second positioning grooves 216 at the corresponding positions on the L-shaped blade holder of the second bayonet removal blade 2. Figure 4 Shown and Figure 5 As shown, the length L1 of the first positioning block 115 and the length L2 of the second positioning block 215 are respectively 0.45 times to 0.55 times the thickness H1 of the first bayonet removal blade head 11 and the thickness H2 of the second bayonet removal blade head 21. In this embodiment, L1 and L2 are respectively 0.5 times H1 and H2. The above measures can reliably position the bayonet removal blade heads.

[0023] like Figure 2 As shown, a first chip groove 117 is provided between the first cutting edge 111 and the second cutting edge 112 of the first bayonet head 11, and the groove surface of the first chip groove 117 is an inclined surface. Figure 3 As shown, a second chip groove 217 is provided on one side of the fourth cutting edge 212 of the second bayonet removal cutter head 21. The bottom of the second chip groove 217 is spherical, which can prevent the chips cut off by rotation from being squeezed into the weld of the anchor chain link which is still at a high temperature.

[0024] The process of removing the welding burrs of the anchor chain ring according to the utility model is as follows:

[0025] 1) The longitudinal middle portion of the anchor chain link 4 to be deburred, with the weld burr on the side thereof, is clamped by the upper and lower jaws of the deburring machine, with the weld burr ring located in the middle of the distance between the upper and lower jaws; the longitudinal plane of the anchor chain link 4 to be deburred is positioned and clamped at a position perpendicular to the plane of the deburring machine body;

[0026] 2) The piston rod of the bayonet removal drive cylinder extends outward, and the right ends of the first bayonet removal blade 1 and the second bayonet removal blade 2 are driven to move toward the welding burr through the movement of the bayonet removal mounting base 3. The first cutting edge 111 and the third cutting edge 211 successively cut the inner and outer sides of the ring body of the anchor chain link 4 to be deburred, dividing the annular welding burr into two unconnected half rings, until the cutting edges of the second cutting edge 112 and the fourth cutting edge 212 are relatively abutted against the corresponding ends of the two half rings;

[0027] 3) The rotating frame of the de-barbering machine rotates around the central axis of its lower end, and the de-barbering knife mounting seat 3 connected to the upper end of the rotating frame drives the second cutting edge 112 of the first de-barbering knife 1 and the fourth cutting edge 212 of the second de-barbering knife 2 to rotate around the longitudinal side ring axis of the anchor chain ring 4. Figure 1 Rotate 180° counterclockwise in the direction of the arrow to complete the removal of the two half rings of welding burrs.

[0028] In addition to the above embodiments, the present invention may also have other implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
