Problems solved by technology

However, the thread rolling effect of the ordinary thread rolling machine for processing the screw is not very ideal, because there is a certain error in the measurement of the actual inner diameter of the barrel, and the wear of the screw is also relatively large.

Abstract

The invention discloses a semi-automatic thread rolling plate which comprises a centrifugal wheel, a connecting rod and a thread rolling part, wherein the centrifugal wheel rotates around a central shaft per se; one end of the connecting rod is rotatably arranged in a peripheral position on one side of the centrifugal wheel; and the thread rolling part is rotatably arranged at the other end of the connecting rod and linearly slides along a horizontal plane. The thread rolling part comprises a thread rolling sliding block and a thread rolling fixed block, a slot only for placing a screw to be processed is reserved between the thread rolling sliding block and the thread rolling fixed block, the adjacent sides of the thread rolling sliding block and the thread rolling fixed block are respectively provided with a thread rolling plate with thread rolling strips, and the thread rolling plates are made of a material with hardness greater than that of the screw to be processed. The semi-automatic thread rolling plate can be used for effectively rolling a thread of the screw through the cooperation of the thread rolling sliding block and the thread rolling fixed block with the thread rolling plates on the adjacent sides. In addition, the slot arranged between the thread rolling sliding block and the thread rolling fixed block can be used for rolling threads of a plurality of screws.

Description

technical field [0001] The invention relates to a semi-automatic thread rolling board. Background technique [0002] The twisted screw should be considered according to the actual inner diameter of the barrel, and the outer diameter deviation of the new screw should be given according to the normal clearance with the barrel; after the thread surface of the worn screw with reduced diameter is treated, it is thermally sprayed with wear-resistant tungsten carbide alloy , and then processed to size by grinding; surfacing wear-resistant tungsten carbide alloy on the threaded part of the worn screw. According to the degree of screw wear, surfacing welding is 1~2mm thick, and then grinding the screw to size. However, the thread rolling effect of the ordinary thread rolling machine for processing the screw is not very ideal, because there is a certain error in the measurement of the actual inner diameter of the barrel, and the wear of the screw is also relatively large.
