摘要： PROBLEM TO BE SOLVED: To easily respond to the dimensional change by attaching a cutting blade having a tip for cutting a burr to a cylindrical tool main body having a plurality of slitting grooves. SOLUTION: A position of a cutting blade 35 is adjusted by a screw 36 in response to the outer diameter of a metal conductive material 22. After that, the metal conductive material 22 is inserted inside a cover 32 till the tip 37 reaches the position of a burr 23. The tool main body 31 rotated manually so that the burr 23 stuck to the outer circumference of the metal conductive material 22 is cut over the whole circumference. Slitting grooves 34 are provided at equal intervals in the circumferential direction in the tool main body 31 and the cover 32. This constitution provides the tool main body 31 with a spring property so as to make the tip 37 surely bite into the burr 23 and respond to the change in the outer diameter of the metal conductive material 22.

摘要： PROBLEM TO BE SOLVED: To prevent a stress from being generated near a filler metal after the curing of a cast material. SOLUTION: This casting mold consists of a top force 1 and a bottom force 2 which are tightly clamped together and a filler metal 24 of a cylindrical shape through which a cylindrical collar 5 is made to penetrate, in cavity 3 formed between both forces 1, 2 and a barlike support pin 6 arranged running through inside the collar 5 via an appropriate space. The support pin 6 has O-rings 7, 7 wound around the former and the O-rings 7, 7 are in contact with the collar 5 and the support pin 6. In the curing process of a liquid cast material packed in the cavity 3, the O-rings 7, 7 are deformed by a force generated by contraction of the cast material and the position of the filler metal 24 is changed within the range of the space to prevent a stress from being generated near the filler metal 24.

摘要： PROBLEM TO BE SOLVED: To eliminate burrs from generating in a casting mold and dispense with cracks due to the burrs and operation to remove burrs from the casting mold. SOLUTION: A bush 11 encircling a part where a metal conductor 4 penetrates a resin (corresponding to a cavity 3 part) is provided, and the outer peripheral side of the bush 11 is surrounded by a casting mold. Since the coefficient of linear expansion of the bush 11 is set higher than that of the casting mold, the bush 11 is expanded not only to the outside, but also to the inside by the casting mold which holds the bush 11 at the time of cast molding. Thus the bush 11 comes into close contact with the metal conductor 4 to prevent burrs from being generated.

摘要： PROBLEM TO BE SOLVED: To provide a method for correcting the inner dimension of a hollow cast item to a required dimension and provide a correcting jig for use in executing the method. SOLUTION: In the correcting jig 1, a nearly cylindrical supporting rod 3 is erected at the center of a base 2 having a crossed shape, in a plan view, and a correcting plate 4 comprising a circular aluminum plate having a predetermined diameter is attached to the vicinity of the upper end of the rod 3. After being heated and hardened, a cast isolation cylinder 11 having a temperature of about 80 deg.C is fitted on the plate 4 so as not to contact it to mount the edge of an opening of the cylinder 11 on supporting parts 21, 21, 21, 21 of the base 2. At that moment, gaps between the plate 4 and the cylinder 11 are kept approximately constant over the entire periphery of the plate 4. Under such conditions, the temperature of the cylinder 11 is cooled to reache a room temperature.

SOLUTION: A casting insulating material 23 is arranged between a lower plate 17 and an upper plate 26, the peripheral part of the upper plate is pressed by the first pressing apparatus 35, and a correcting jig of a casting insulating material 23 which pressed the other end of a conductor 25 by the second pressing apparatus is mounted on a roller conveyer, transported to a heating oven, and heated to a strain removing temperature in the oven. The jig is taken out from the oven after the completion of heating and cooled gradually by radiation so that the correction of the insulating material 23 to correct a casting resin 24 is carried out to the precision of the lower plate 17 and the upper plate 26. When the insulating material 23 is cooled after heating, a casting resin 24 is pressed by the first pressing apparatus 35 following the shrinkage.

摘要： PROBLEM TO BE SOLVED: To easily respond to the change in a chamfering dimension by attaching a blade to a tool main body in such a state as freely rotating and axially reciprocating and by attaching a stopper, which regulates the movement of the blade in relation to the tool main body in the inserting direction in an opening part, to the blade. SOLUTION: A push-in distance of a blade 24 in the depth direction of a filler metal 2 is regulated by bringing a ring 26 in contact with a bearing 22. The bearing 22 and the ring 26 are arranged with an abutment face of the tool main body 21 to an injection type insulating material 1 set to the standard so that a desired chamfering dimension can be obtained stably. When the chamfering dimension is changed, the blade 24 is detached from the tool main body 21 so that the thickness and the position of the ring 26 or the depth of the tool main body 21 can be changed. Namely, the stroke of the blade 24 can be changed by exchanging or deviating the ring 26 or exchanging the tool main body 21.
