Abstract
The utility model discloses a needle bar ring blank for a sewing machine. The needle bar ring blank comprises a head (1) and a connection bar (2) which are connected with each other; the head (1) is cuboid-shaped; and the connection bar (2) is cylindrical. The needle bar ring blank for the sewing machine saves materials; and a method for processing the needle bar ring blank comprises a few steps, so that the reduction of accuracy of a finished product can be avoided.
Description
Technical field
The utility model relates to the accessaries of sewing machine technical field, specifically is that a kind of needle bar of Sewing machines is embraced blank.
Background technology
The needle bar of Sewing machines is embraced and is comprised head and the columniform connecting rod that is cuboid.Present needle bar is embraced the steel that blank generally all adopts cuboid, after the length cutting, and head and connecting rod that the reprocessing needle bar is embraced.It is big to be processed into columniform connecting rod waste of material to the steel of cuboid like this, and needs through multiple working procedure processing, and manufacturing procedure is many, and needs the multiple clamping location, reduces finished product accuracy greatly.
The utility model content
The technical problem that the utility model will solve is, provides a kind of and can save that material, manufacturing procedure are few, the needle bar of the Sewing machines of avoiding reducing finished product accuracy is embraced blank.
The technical scheme of the utility model is, provides a kind of needle bar with Sewing machines of following structure to embrace blank, comprises continuous head and connecting rod, and said head is cuboid, and said connecting rod is cylindrical.
After adopting said structure; The needle bar of the utility model Sewing machines is embraced blank compared with prior art, has the following advantages: because said connecting rod is cylindrical, just adopt the processing mode of cold-heading; The preliminary shape of the columniform connecting rod of embracing needle bar processes; Directly carry out preliminary working and fine finishining then, can save material like this, also reduced manufacturing procedure; And reduce clamping location number of times, avoid reducing the precision of finished product.
Description of drawings
Accompanying drawing 1 is the structural representation that the needle bar of the utility model Sewing machines is embraced blank.
Accompanying drawing 2 is schematic side view of Fig. 1.
Shown in the figure, 1, head, 2, connecting rod.
