Fastener parts forming
1.Purpose: to achieve the shape and length (or thickness) of semi-finished product by cold forging (or hot forging) of wire rod.
2. Bolt or screw head forming :

    Machine models (specifications) selection: machine models RBF-63S,RBF-83S,RBF-103S, RBF-133S; RBF-64S,RBF-84S,RBF-104S,RBF-134L. Suitable for M6,M8,M10,M12. Length range 40-200mm,

   Operation process:

1. Hexagon bolt (four die four stroke or three die three stroke)

(a), cutting: through the movable scissors one-way movement, the wire stuck in the cutting die cut into the required material.

(b), a punch: after the die against the blank material punching die extrusion blank material, preliminary molding, and then the blank material will be pushed out after the die.

(c) Second punching: the blank material enters the second punching die, the second punching die extrudes the blank material, and the blank material is flat and round, and then the latter punching die pushes the blank material out.

(d) Three punching: the blank material enters the third punching die, and the hexagonal head of the blank material is initially formed by cutting through the hexagonal three punching die. After that, the latter punching die pushes the blank material into the third die, cutting from the hexagonal head cut, hexagonal head formed.

2. Carriage bolt (one die and two stroke)

3. Hex socket bolt (three die and three stroke)

4. Hexagon washer head small screw (three die three stroke)

5. Small screw (general head type, one die and two strokes)

(a), cutting: through the movable scissors one-way movement, the wire stuck in the cutting die cut into the required material.

(b), a punch: the punching die is fixed, a punch die will preliminarily shape the head of the product, so that the next stroke can be fully formed. When the product is furrowed for a word,

A die for concave, elliptical groove, product for cross groove, a die for concave, square groove.

(c) Two punching: after the first punching, the punching tool runs as a whole, the two punching dies move to the front of the punching die, and the two punching dies move forward at the same time, and the product is finally finished type. After that, the blanking material is pushed out by the rear punching rod..
3.Hot forging:

  Applicable Specifications: Product Name: Hexagon Wood Screw Bundle Bar Carriage Bolts Un Bundle Bar Carriage Bolts Hexagon Bolts
(a). Heating: Heating the end of the blank material to be molded by the heating equipment to the white-hot state, and setting the heating temperature and time according to the product specifications. General 3/4 to lower heat for 7-10 seconds, 7/8-1 "heat for about 15 seconds.

(b),Forming: the heated blank material quickly moved to the molding machine, through the back seat, clamping die fixed, head die impact blank material, add molding. It can be based on embryo

The length of the material adjusts the distance of the backseat.

(c)Bundle rod: the product is shrunk by extrusion on the bundle rod machine.
4. Nut  forming:

    Machine model (specification) selection: machine model JXR-08B, JXR-11B, JXR-14B, JXR-19B, JXR-24B,JXR-33B, applicable range M5 and 10# following M8 and 5/16,M10 and 3/8 and M12 and 1/2 and M16 and 5/8 and M20 and 7/8 and M24 and 1"

   Operation process:

(a), Cutting: by the inner knife die (410) and shear knife (301), the wire is cut into the required blank material.

(b), A punching: by the front punching die (111), stroke die (411), after the punching bar (211), will be uneven deformation cut off the blank material to be reshaped, and the blanks are pushed out by the rear punch rod (211).

    Second blanking: the running clamp (611) clips the blank material from the first blanking to the second blanking, which is matched by the front blanking die (112), the stroke die (412) and the rear blanking rod (412)

To further reshape the blank material, and strengthen the flattening and filling effect of the first stroke, and then push the blank material out with the rear stroke bar (212).

    Three blanking: the running clamp (612) clips the blank material from the second blanking to the third blanking, which is equipped with the front blanking die (113), the stroke die (413) and the rear blanking rod (213)

And the blanks are extruded again so that the down thrust can be fully formed, and then the blanks are pushed out by the back thrust rod (213).

   Four-punch: the running clip (613) clips the blank material from the third punch to the fourth punch, which is equipped with the front punch die (114), the stroke die (414) and the rear punch rod (214)
