JESENTECH Customization of SUJ2 precision Stepped cylindrical dowel pin for Mould making

Step type locating pin:

Part that participates in limiting the degree of freedom of the object, has certain applications in some mechanical motion equipment, mainly used for position determination in two-dimensional space.

Locating pins include:

External thread locating pin, internal thread locating pin, stainless steel locating pin, polygonal locating pin, straight locating pin, locating pin for welding fixture, shoulder locating pin, spring locating pin, stepped locating pin , elastic cylindrical pin, etc.

The stepped positioning pin can ensure the height of the pin when it is installed. The cylindrical pin is currently made of high quality carbon structural steel as raw material. Under normal circumstances, the material is mostly C35, C45, but heat treatment is required. Bearing steel is selected for high strength requirements.

Introduction to the types of Pin:
1, pin is a more common in our lives, whether it is now or ancient existence, and the use of pin in ancient times has been particularly prominent, the role of pin in the house, basically have marketing, There are pins to connect and strengthen, so that ancient houses can be strengthened to combat natural disasters, and now the pin is basically applied to machinery, pin role is positioning, connecting, locking, and even disassembly. And the kind of marketing is also developed to a lot of kinds, each kind of marketing is not the same as the place where it is applied.
2, the types of pin are: U-pin, semi-circular key, closed pin, cone pin, hole pin, step pin, elastic pin, pin shaft, positioning pin, T-pin, opening pin, other keys, cylindrical pin, combined insurance pin, etc. From so many names you can see that they are applied to different fields and areas.
3, the action of step pin is what cone pin Φ 8 × 50, taper is 1:50, this pin small diameter is 8 mm, big end is 9 mm. The machining method is to drill an 8 mm hole with an 8 mm drill bit and then reel the large head of the hole to 9 mm with an 8 mm 1:50 cone reamer to OK. If you want to save effort, you can punch the bottom hole into a step hole, increasing 0.2 mm for each length of 10 mm. Standard 8 mm 1:50 reamer market available.
4, the classification standard of pin can be divided into: small positioning pin, fixed positioning pin, interchangeable positioning pin and positioning pin according to its structure.
