の効果が非常に大きい。Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an apparatus for removing welding burrs generated by butt resistance welding or the like. 2. Description of the Related Art As a welding machine for continuous rolling equipment, for example, JP-A-52-43754 and JP-A-58-151 are disclosed.
For example, there is a flash welding machine (or flash butt welding machine) disclosed in JP-A-971 and JP-A-61-30287. The welding machines shown in these figures perform continuous rolling by joining the cast billets and blooms one after another at the rolling mill entrance side, and eliminate the end of the steel sheet when winding the steel sheet into a coil shape. Is used to improve productivity by continuously generating, for example. [0003] In the above-described flash welding machine, welding burrs are generated by flashing and pressurizing in a billet, a bloom, or a welded portion of a steel plate. In order to cause trouble, it is necessary to remove it using a deburring device or the like. Deburring is a very important step, especially when shipping a welded part as a product. [0004] Weld burrs are generated in the form of stripes in the width direction of the material to be welded. When this is removed by cutting, it is usually cut in the direction along the burrs, but when the joining cross section is relatively small, such as a steel plate, the generated welding burrs are small and the cutting resistance is small, so it crosses the burrs. It may be cut in the direction. [0005] Regardless of the direction, burrs generated when a steel plate is welded and joined have been conventionally removed, and various methods have been devised. [0006] However, when the welding joint surface is large, such as a billet or a bloom,
The generated welding burrs also increase, and the cutting load also increases.
Therefore, when cutting off this burr, it is desirable to cut in the longitudinal direction of the burr in consideration of the cutting resistance,
There are few effective deburring devices corresponding to this. [0007] Further, a number of devices for removing burrs (called burrs) generated at the edges of the material to be welded after cutting and removing the welding burrs have been devised, but sufficient effects have been obtained. There are few things. An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a simple and efficient welding burr cutting and removing apparatus. [0009] To achieve the above object, the present invention provides a construction in which a cutting blade having an arbitrary cutting edge shape and a cutting blade formed on a surface of a welded joint of a material to be welded are formed. A drive mechanism for moving the cutting blade from one side of the workpiece to the other side so as to cut and remove welding burrs, and fitting the cutting blade shape of the cutting blade to the shape projected in the cutting direction. Welding burr cutting and removal characterized by comprising a fitting having a matching shape and pressed against the other side of the material to be welded, and a drive mechanism for pressing the gold against the other side of the material to be welded. Device. " Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 5 show the operation of an embodiment of the welding burr cutting and removing apparatus according to the present invention step by step. FIG. 1 shows a state before the start of cutting, in which the cutting blade 1 and the backing plate 3 are located at positions retreated from the billet 10 and face along the longitudinal direction of the welding burr 11 generated on the surface of the billet 10. The state is shown. This welding burr 11
Are located on the upper and lower surfaces of the billet 10, respectively, so that one cutting blade 1 is used for each welding burr 11. Since the welding burr 11 does not have a clear boundary with the base material of the billet 10, the welding burr 11 may be partially removed from the base material of the billet 10. FIG. 2 shows that, as a preparatory operation before the start of cutting, the contact metal drive mechanism 4 is operated, and the contact metal 3 is attached to the cutting end side surface 10b of the billet 10 where the welding burr 11 ends.
Is shown. At this time, it is also possible to operate the cutting blade drive mechanism 2 at the same time to keep the cutting blade 1 close to the cutting start end side surface 10a of the billet 10. FIG. 3 shows a state in which the cutting blade 1 is moved in the longitudinal direction of the welding burr 11 by the cutting blade driving mechanism 2 while the contact metal 3 is pressed against the cutting end side surface 10b of the billet 10 so that the cutting burr 11 is removed. It shows the state in which it is going. Any shape can be used as the shape of the cutting blade 1,
In this embodiment, a cutting blade having an arc shape is used so that a step due to the edge of the cutting blade does not remain in the billet. FIG. 4 shows a state in which the cutting and removal of the welding burr 11 has been completed. The cutting blade 1 continues to move in the cutting direction by the cutting blade driving mechanism 2 even after the cutting and removal of the welding burr 11 is completed and the cutting blade 1 passes through the cutting end side surface 10b of the billet 10. At this time, the cutting edge shape and the contact metal shape of the cutting blade are:
The shapes are fitted to each other so that a minute gap is formed to prevent interference. That is, when viewed from the cutting direction, the projected shape of the cutting blade and the projected shape of the backing metal are:
It has a shape that fits through a minute gap. FIG. 5 shows that after the cutting blade 1 has passed over the cutting end side face 10b of the billet 10 and overrun by an appropriate amount of movement, the cutting blade 1 is driven by the cutting blade drive mechanism 2 and the abutment 3 is applied. 3 shows a state in which the gold driving mechanism 4 has been retracted. As shown in FIG. 6, when the welding burrs 11 of the billet 10 to be welded are removed by cutting, the phenomenon that uncut portions called burrs 12 occur on the cutting end side surface 10b is caused particularly by the material to be welded. Appears significantly at high temperatures. As an example, the temperature of the material to be welded is 800 to 1000.
When the temperature is around 0 ° C., a welding burr having a triangular cross section with a height of 10 mm and a base of 20 mm is cut into a 1 mm cut from the surface of the material to be welded.
(Excluding welding burrs), cutting speed 100mm / sec
In the case of cutting off using a cutting blade with a rake angle of 0 °,
Even when the gap between the cutting blade and the backing plate is about 3 mm, the above-mentioned burrs are reduced, but it has been found that it is particularly desirable to set the gap to 1 mm or less. If the rigidity of the entire cutting device is high, it is desirable to further narrow the gap, but it is preferable to set an optimum gap in consideration of the allowable size of burrs. In the case of a hot steel material as described above, the thickness is preferably about 0.1 to 1 mm. According to the present invention described above, the apparatus is simple, and it is difficult for the uncut portion called "burr" to be generated on the end surface of the material to be welded after the welding burr is removed. An additional process such as a shaping process is not required, and good welding burrs can be cut and removed in a short time. Therefore, especially in an online manufacturing apparatus such as continuous rolling, the effect of improving productivity is very large.
