Machining method for special-shaped guide groove

Abstract

The invention provides a machining method for a special-shaped guide groove. The machining method is characterized in that a special fixture is adopted and comprises two parallel guide baffles fixed to a bottom plate; a pressure bearing support is fixed to one side of a position between the two guide baffles, a pressing support in sliding fit with the two guide baffles is arranged in the middle ofthe position between the two guide baffles, and a lead screw mounting plate is fixed to the other side of the position between the two guide baffles; lead screws are uniformly arranged on the lead screw mounting plate; a structure matched with an inner working surface and an outer working surface of the special-shaped guide groove is arranged between the pressure bearing support and the pressingsupport; and the pressing support provides pressure through the lead screws. The machining method for the special-shaped guide groove particularly comprises the steps of adopting laser cutting blanking (the shape and hole positions of a sheet are formed through laser cutting blanking); coiling the sheet for primary forming; using the special fixture for extrusion forming; and performing spot welding fixing on end ports to achieve process supports, and carrying out discharging to complete the operation. The machining method for the special-shaped guide groove is suitable for machining productswith similar structures, the production efficiency and the material utilization rate can be improved, the work intensity of workers can be reduced, the appearance quality can be improved, and the problems of labor consuming, material wastes, low efficiency and poor appearance quality can be solved.

Description

technical field [0001] The invention relates to the technical field of processing special-shaped parts, in particular to a processing method for special-shaped guide grooves. Background technique [0002] In order to meet the different requirements of customers, it is necessary to produce a special-shaped guide groove. The special-shaped guide groove is a semi-circular arc-shaped groove, and the radius gradually increases from one end of the groove to the other end. The inner side of the semi-circular arc is the inner working surface. The outer side of the semicircular arc is the outer working surface, and the working surface is provided with through holes. [0003] The inventor finds in the process of realizing the present invention: [0004] The traditional processing technology used in similar structures is: lower material→drilling→shaping→roasting and bending, but this method cannot meet the actual production requirements. If the construction is forced, it will not only...
