Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.

Referring to fig. 1 and 2, the forming tool for processing the double-sided welding groove of the plate comprises a tool handle 1 and a tool bit 2, wherein an annular groove 4 is formed in the tool bit 2, four groups of V-shaped convex edges 3 are arranged in the annular groove 4, and the V-shaped angle of each V-shaped convex edge 3 is consistent with the angle of the welding groove required by the plate; the four groups of V-shaped ribs 3 are uniformly distributed in the circumferential direction of the knife handle 1 and are centrosymmetric. One side of the V-shaped convex edge 3 is provided with a screw hole for clamping a machine clamping blade 5. Each threaded hole clamps a machine clamp blade 5, the machine clamp blade 5 is clamped on the V-shaped convex edge 3 of the cutter head through a screw 6, and the gap between the blade and the blade is controlled within 2 mm. This shaping cutter belongs to gang tool, earlier with tool bit 2 and 1 equipment of handle of a knife, assemble the threaded hole of pretension V type bead 3 on tool bit 2 with screw 6 with quick-witted clamp blade 5 after the equipment, guarantee that the cutting edge of quick-witted clamp blade 5 aligns each other, the angle that every group of quick-witted clamp blade formed after the alignment is unanimous with the 3 angles of V type bead on the tool bit 2, make up into two-sided welding groove shaping cutter with screw 6 after with every group of quick-witted clamp blade 5 aligns the pretension. After being combined, the combined plate is assembled with boring and milling machine equipment, the direction of a cutting edge of a blade group is ensured to be consistent with the rotation direction of a main shaft of the equipment, and a double-side welding groove of the plate is processed to the size.

Referring to fig. 3, the clamping blades 5 arranged at the left and right positions on the same side of the same group of V-shaped ribs 3 are distributed in odd-even distribution. Meanwhile, the machine clamping blades 5 at the same positions of the adjacent V-shaped ribs 3 are arranged in a staggered manner, namely: when the V-shaped angle of the rib is taken as a dividing line, and an even number of machine clamping blades 5 are arranged on one side of the side surface of the former V-shaped rib 3, an odd number of machine clamping blades 5 are arranged at the same position of the side surface of the latter V-shaped rib 3. When the other side of the former V-shaped rib 3 is provided with odd machine clamping blades 5, the same position of the side of the latter V-shaped rib 3 is provided with even machine clamping blades 5. The mode that the same side, the front side and the rear side are arranged in an odd-even staggered mode can completely eliminate cutting traces left by the front group of blades in the machining process when the next group of blades are used for cutting.
