Description

A support for reaming ring parts

technical field

The invention belongs to the forging technology, and relates to a support used for reaming a ring part.

Background technique

When reaming ring forgings on free forging equipment, use two anvils as horse frames, put the horse bar on the horse frame, and then ream the forging blank that is placed on the horse bar to be reamed. In order to prevent the displacement of the carriage, it is necessary to manually use the clamps to hold the two anvils. Its shortcoming is: the first, risk is big, there is very big hidden danger to operator's safety. Second, the labor intensity is high. Third, the operation is complicated, and it is easy to cause the temperature of the forging to drop too quickly, requiring repeated reheating, resulting in a long production cycle and low work efficiency.

Contents of the invention

The object of the present invention is to propose a support for reaming ring parts, so as to eliminate potential safety hazards to operators, reduce labor intensity, shorten production cycle and improve work efficiency.

The technical solution of the present invention is: a support for reaming ring parts, which is characterized in that it consists of an anvil 1, two splints 2 with the same structure, two support plates 5 with the same structure, and four screw components 4 and two hinge shaft assemblies 7; anvil 1 has a cuboid shape, splint 2 is a rectangular plate, and the outer surface of splint 2 is welded with double lugs 3 with shaft holes, and the axes of the double lugs 3 shaft holes are aligned with the The long side of the splint 2 is parallel to and higher than the upper side of the splint 2, the ear groove between the two lugs of the double ear 3 is perpendicular to the long side of the splint 2, on the splint 2, on both sides of the double ear 3, near the short side of the splint 2 There are two bolt holes arranged up and down on each side, and the inner surfaces of the two splints 2 are attached to the two end faces of the anvil iron 1 along the length direction respectively. The surfaces are parallel, and the two splints 2 are connected to the anvil iron 1 as a whole through four screw assemblies 4; Matched single ear 6 with shaft holes, the single ear 6 is located in the ear groove of the double ear 3, the middle section of the hinge shaft assembly 7 is the optical axis section, and both ends have external threads, the optical axis section of the hinge shaft assembly 7 Go through the shaft hole of the double ear 3 and the shaft hole of the single ear 6, the optical axis section of the hinge shaft assembly 7 is in transition fit with the shaft hole of the double ear 3, and the optical axis section of the hinge shaft assembly 7 keeps rotating with the single ear 6 gap, the two ends of the hinge shaft assembly 7 are fastened by nuts, so that the support plate 5 and the splint 2 form a hinge connection; when the inner surface of the support plate 5 is in a vertical state, the lower side of the support plate 5 and the upper surface of the anvil 1 Fitting, at this moment, two support plates 5 form the horse frame that supports the horse bar.

The invention has the advantages of providing a support for reaming ring parts, which eliminates potential safety hazards for operators, reduces labor intensity, shortens production cycle, and improves work efficiency. Tests have proved that after adopting the invention, the working efficiency of hole reaming is increased by more than 3 times.

Detailed ways

The present invention will be described in further detail below. Referring to Fig. 1 to Fig. 5, a support for ring reaming is characterized in that it consists of an anvil 1, two splints 2 with the same structure, two support plates 5 with the same structure, and four screw components 4 and two hinge shaft assemblies 7; anvil 1 has a cuboid shape, splint 2 is a rectangular plate, and the outer surface of splint 2 is welded with double lugs 3 with shaft holes, and the axes of the double lugs 3 shaft holes are aligned with the The long side of the splint 2 is parallel to and higher than the upper side of the splint 2, the ear groove between the two lugs of the double ear 3 is perpendicular to the long side of the splint 2, on the splint 2, on both sides of the double ear 3, near the short side of the splint 2 There are two bolt holes arranged up and down on each side, and the inner surfaces of the two splints 2 are attached to the two end faces of the anvil iron 1 along the length direction respectively. The surfaces are parallel, and the two splints 2 are connected to the anvil iron 1 as a whole through four screw assemblies 4; Matched single ear 6 with shaft holes, the single ear 6 is located in the ear groove of the double ear 3, the middle section of the hinge shaft assembly 7 is the optical axis section, and both ends have external threads, the optical axis section of the hinge shaft assembly 7 Go through the shaft hole of the double ear 3 and the shaft hole of the single ear 6, the optical axis section of the hinge shaft assembly 7 is in transition fit with the shaft hole of the double ear 3, and the optical axis section of the hinge shaft assembly 7 keeps rotating with the single ear 6 gap, the two ends of the hinge shaft assembly 7 are fastened by nuts, so that the support plate 5 and the splint 2 form a hinge connection; when the inner surface of the support plate 5 is in a vertical state, the lower side of the support plate 5 and the upper surface of the anvil 1 Fitting, at this moment, two support plates 5 form the horse frame that supports the horse bar.

In order to prevent the horse bar from moving substantially, there is a groove 5a with a flat groove bottom on the side of the support plate 5, the groove bottom of the groove 5a is parallel to the upper surface of the anvil iron 1, and supports the horse of the reamed forging. The lower surface of the bar is attached to the groove bottom of the groove 5a.

The practical method of the present invention is: first clamp the two support plates 5 with pliers and turn them outwards, separate the horse frame, and expose the anvil iron 1, and then carry out pier thickening and punching operations; Take off the iron 1, clamp the two support plates 5 with pliers, turn them inward to form a horse frame, and carry out the hole reaming operation after installing the horse bars.
