spanner manufacturing process

Most spanners are manufactured using one of two processes- they are either forged and machined or they are cut. Cut (or stamped) spanners tend to be very

It involves cutting dies that can be used a number of times to produce different parts of hand tools. The process is carried by pouring molten material, usually 

The method (4) of making a spanner (8) according to claim 1, wherein said second end stamping step (44) forms said second arch-shaped part (d2) by pressing said 

We are professional hand tools machine supplier around the world, like production line for pliers, adjustable wrench, spanner, socket, screwdriver, 

Spanner selection Selecting which spanner to use depends on the job at hand, but as a general rule the first choice should be a socket. This offers the advantage of surrounding the nut or head of the bolt entirely, which minimises the possibility of slipping. A socket has contact on six points of the hexagon, compared with an open-ended spanner, which has only two contact points

At present, there are two kinds of wrench spanner manufacturing processes: one is casting, the other is wrench spanner forging process. Is Spanner / Wrench Cast or Forged? 1, Spanner wrench casting process Melt the bar into liquid state, then pour it into the die cavity with spanner shape, and wait for it to solidify to form a complete spanner.

A spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or

Flatbed die cutting, also referred to as steel rule die cutting, is a fabrication process which employs a flatbed die cutting press and custom steel rule dies to convert the material into custom shapes and designs. This process is suitable for processing thicker material, producing larger parts, and completing small orders or short production runs.

The invention relates to a manufacturing method for a spanner. The manufacturing method comprises the steps: S1, providing a workblank; S2, carrying out hot trimming and turning on the workblank provided in the S1 to form the spanner, wherein the spanner comprises a handle portion and a head portion at least arranged at one end of the handle portion; S3, carrying out surface heat treatment on
