Outer hexagon machining device for head of stainless steel hexagonal head bolt

Abstract

The invention relates to an outer hexagon machining device for the head of a stainless steel hexagonal head bolt. The outer hexagon machining device comprises a lower mold plate, a lower fixing seat, a lower mold core, a concave mold seat, a base plate, a left guide column, a supporting plate, a left guide sleeve, an upper mold plate, a mold handle, a spring, a beating block, a right guide sleeve, a right guide column, a first stopper screw, a concave mold and a second stopper screw. The lower fixing seat is fixed to the upper middle portion of the lower mold plate through a screw, and the lower mold core is fixed to the middle portion of the lower fixing seat through the second stopper screw. The concave mold seat, the base plate, the supporting plate and the upper mold plate are sequentially overlapped together and fastened together through the screws. The left guide column and left guide sleeve and the right guide sleeve and right guide column are oppositely arranged between the lower mold plate and the upper mold plate. The spring is arranged in the supporting plate, and the mold handle is arranged in the center of the upper mold plate and is in interference fit with the upper mold plate. The outer hexagon machining device is a self-designed machining device in the practice process and is simple in structure and low in cost, most importantly, the defects generated by a traditional machining process can be overcome, and the production efficiency and the product quality can be improved.

Description

Technical field [0001] The invention belongs to the field of mechanical processing, and particularly relates to a stainless steel hexagonal head bolt head outer hexagon processing device. Background technique [0002] In the existing mechanical processing method of the hexagonal outside of the stainless steel hexagon head bolt head, the commonly used method is to use the punching method to cut the cylindrical head into hexagons. When the upper mold part descends to the concave mold to contact the workpiece and the punching is completed, The waste material has not separated from the workpiece, and there is about 0.3mm~0.5mm connected with the original workpiece. When the upper mold part moves upward, the workpiece moves upward with the die. The operator puts down the next workpiece, and then the upper mold part moves downward for the second time. The bottom end of the undetached workpiece is in contact with the upper end surface of the newly placed workpiece, and the previous work...

[0002] In the existing mechanical processing method of the outer hexagonal head of the stainless steel hexagonal head bolt, the commonly used method is to cut the cylindrical head into hexagonal by punching. When the upper die part goes down to the die to contact the workpiece and the punching is completed, The waste has not separated from the workpiece, and there is still about 0.3mm~0.5mm connected to the original workpiece. When the upper mold part goes up, the workpiece goes up with the die, and the operator puts down another workpiece, and then the upper mold part goes down for the second time. The bottom of the undetached workpiece is in contact with the upper surface of the newly placed workpiece, and the previous workpiece is pushed out of the die by the recoil force, thus completing the edge trimming of a workpiece; however, this method is only feasible for carbon steel; cutting stainless steel The shank bends when bolting
