Description

Metal seamless chain

The technical field is as follows:

the utility model relates to a chain processing field, concretely relates to metal seamless chain.

Background art:

generally, the metal chains in the market are mainly divided into two types by the existence of gaps and no gaps, the seam-welded strip is usually used for the condition of low strength requirement or material unable to be welded, and the seamless strip is usually used for the condition of high strength requirement or high appearance requirement.

The typical manufacturing method of the steel bar is that the rod-shaped material is cut and bent into a closed loop shape to form open-loop chain particles, and then the rod-shaped material after the next section of cutting passes through the open-loop chain particles and is bent; and finishing the manufacturing of the steel strip after repeating the action, welding to manufacture the seamless steel strip if the seamless steel strip is required, and performing the seamless steel strip if the seamless steel strip is not required.

Wherein, the seamless steel bar is only suitable for the material which can be welded, the base material of the seamless steel bar is iron, and the welding method is used; resulting in a seamless finished bar that is clean and difficult to master.

The utility model has the following contents:

the utility model aims to solve the technical problem that a metal seamless chain is provided.

The utility model discloses the technical problem that will solve adopts following technical scheme to realize: the utility model provides a metal seamless chain, includes endless chain and ring-opening chain circle, ring-opening chain circle is provided with the fracture, endless chain passes through fracture and ring-opening chain circle swing joint, fixedly connected with fills the section between the fracture of ring-opening chain circle.

Preferably, the broken ends of the open-loop chain ring are provided with toothed butt joint layers.

The utility model has the advantages that: the utility model discloses simple structure, convenient and practical can make seamless chain through metal ejection forming technique, and the fracture department of chain realizes the sealed of fracture department through packing, sintering to improve the efficiency of production, strengthen the intensity and the effect of product.

Description of the drawings:

in order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts;

fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic structural view of the middle dead-cycle chain and the open-loop chain ring of the present invention;

FIG. 3 is a schematic structural view of the middle open-loop chain ring of the present invention;

FIG. 4 is a schematic structural view of the middle open loop chain of the present invention after being filled;

wherein: 1. a dead-cycle chain; 2. opening a chain ring; 3. breaking off; 4. a toothed butt joint port; 5. and (6) filling the section.

The specific implementation mode is as follows:

in order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Example 1: as shown in figure 1-, the metal seamless chain comprises a closed loop chain 1 and an open loop chain ring 2, wherein the open loop chain ring 2 is provided with a fracture 3, the closed loop chain 1 is movably connected with the open loop chain ring 2 through the fracture 3, and a filling section 5 is fixedly connected between the fractures 3 of the open loop chain ring 2.

Preferably, the teeth-shaped butt joint layers 4 are arranged at the fracture 3 ends of the open-loop chain ring 2, so that the joint strength of the fracture is enhanced.

Example 2: as shown in fig. 1-4, a metal seamless chain comprises a closed loop chain 1 and an open loop chain ring 2, wherein the open loop chain ring 2 is provided with a fracture 3, the closed loop chain 1 is movably connected with the open loop chain ring 2 through the fracture 3, and a filling section 5 is fixedly connected between the fractures 3 of the open loop chain ring 2.

Preferably, the fracture 3 ends of the open-loop chain ring 2 are provided with tooth-shaped butt joint layers 4.

The processing steps are as follows:

1. a three-cavity mold is manufactured.

2. The mold was mounted on an injection molding apparatus and injection was performed.

2.1, after the first injection is finished, a dead-cycle chain ring and an open-loop chain ring with a special shape at the opening at the two sides and to be connected can be obtained.

And 2.2, assembling the open-loop chain ring and the closed-loop chain ring.

2.3, placing the open loop portion of the assembled chain loop into a mold cavity and performing a covering and injecting process, which will fill up the two portions to be connected and the span.

2.4 repeating the above steps to obtain the raw embryo of the chain.

3. Degreasing and sintering the green blank according to the characteristics of raw material feeding; so as to obtain the seamless metal strip with the rings buckled with each other.

The highest degreasing temperature can be 110 ℃, and the time is 6-10 hours; the highest sintering temperature can be 1280-1380 ℃ for 15-24 hours.
