Description

A kind of structural chain

Technical field

The utility model relates to chain production technical fields, and in particular to a kind of structural chain.

Background technique

Currently, for the delivery chain in underground coal mine coal working face and haulage drift, as key component and vulnerable part, Its structure is staggeredly to be worked out by a certain number of flat rings with vertical ring, stands ring straight-arm part and uses rectangular cross section structure, reduces Vertical ring height, by taking 38 × 126mm specification chain as an example, the more conventional round-link chain outer width of compact chain reduces 12mm, such as Fig. 1 and Fig. 2 Shown, (Fig. 1 is conventional round-link chain, and Fig. 2 is compact chain), the compact chain of this structure has in the limited underground work face in space Clear superiority.But since in the production of compact chain, Li Huan manufacturing process is cumbersome, quality control is always in compact chain production Short slab.

Vertical ring manufacture common are two kinds of techniques at present, and one is compile together after blanking forging establishment ring with flat ring bar Chain, this scheme complex procedures found ring manufacturing process flow: blanking → heating → bat is flat → blocking → finish-forging → punching → trimming Outer overlap → milling inner hole → normalizing → shot-peening → reconditioning inner burr → the chaining of → reconditioning, the technique to equipment precision, process, Material property, operating technology and tooling required precision are higher, and technology stability is poor；It is exactly that we are currently used there are also one kind Technique founds ring manufacturing process flow: blanking → bat is flat → chaining, and for forging vertical ring, the process process is simple, Processing performance stability is preferable, but due to vertical ring more than flat ring the flat process of bat so that blanking procedure and establishment chain link process it Between there are time hysteresis cycle, there are also rooms for promotion for working efficiency, and it is also more difficult to control to clap flat process length dimension, once go out Existing dimension overproof, needs to increase amendment process, for can not be modified overproof, will directly affect product quality, even results in batch Secondary property bar is scrapped, and then influences manufacturing schedule.

Utility model content

(1) technical problems to be solved

Technical problem to be solved by the utility model is: how to design a kind of novel knot that can be improved chain production efficiency Structure chain.

(2) technical solution

In order to solve the above-mentioned technical problem, the utility model provides a kind of structural chain, including vertical ring bar, the structure The cross section of the vertical ring bar of chain is formed by stacking by semicircle and rectangle, one as the rectangle of the semicircular diameter Long side, the semicircular diameter are 38 ± 0.2mm, and the size of the rectangle is 38 × 10mm, and the rectangle is as chaining When the supporting surface placed on workbench.

Preferably, the finished product vertical chain ring outer surface of the structural chain is rectangle.

Preferably, the rectangle of the finished product vertical chain ring outer surface of the structural chain, width 38mm, with a thickness of 29mm.

Preferably, the finished product vertical chain ring inner surface of the structural chain is arc-shaped.

Preferably, the arc diameter of the finished product vertical chain ring inner surface of the structural chain is φ 38mm.

Preferably, the structural chain further includes flat ring.

Preferably, the semicircular diameter is 38mm.

(3) beneficial effect

The utility model has the advantage of do not need forging process, the production cycle is shortened in direct chaining after blanking, improves Production efficiency；Finished product vertical chain ring outer surface is full rectangle, further decreases vertical ring height, saves space, is more applicable for coal mine Working environment in down-hole coal excavation working face and haulage drift；Finished product vertical chain ring inner surface be it is arc-shaped, can work with flat ring Face is mutually coordinated, will not interfere；Human and material resources and time are saved, economic cost is reduced；Surface quality is good, and bar is transversal Face size distribution is small, dimensionally stable, can be used as chain dimension continually and steadily reliable powerful guarantee, avoids due to forging work The risk of finished product compact chain poor dimensional stability caused by sequence energy is unstable.

Specific embodiment

To keep the purpose of this utility model, content and advantage clearer, with reference to the accompanying drawings and examples, to this reality It is described in further detail with novel specific embodiment.

In the compact chain manufacturing process of the utility model, vertical ring bar specification is improved, so that vertical ring bar material baiting After can be directly with the direct chaining of flat ring bar, by taking 38 × 126mm specification compact chain as an example, schematic diagram is specifically such as Fig. 3, Fig. 4 With shown in Fig. 5.

Fig. 3 is conventional vertical ring bar, and specification is φ 38mm, and bar cross section is circle, and diameter 38mm ± 0.2mm, Fig. 4 are Compact vertical chain ring blanking schematic diagram, cross section are the rectangle that there is arc transition in quadrangle, and Fig. 5 is the structure vertical chain ring of the utility model Bar, bar cross section are formed by stacking by semicircle and flat rectangle, semicircle 38 ± 0.2mm of diameter, and flat rectangular dimension is 38 × 10mm, the 10mm height of rectangular section stablize the supporting surface placed when can be used as chaining on workbench.When production, do not need Manufacturing procedure is forged, according to a conventional method with the direct chaining of flat ring bar after blanking.After chaining stand ring structure as shown in fig. 6, Finished product vertical chain ring outer surface be full rectangle, width 38mm, with a thickness of 29mm, inner surface be it is arc-shaped, diameter be φ 38mm.With Conventional round-link chain is compared, which, which founds ring height, reduces 16mm or more, is produced using this kind of bar blanking chaining, is not needed to forge It makes and claps flat process, structural chain manufactures complete process flow: ring is found in blanking → chaining → ball blast → weldering flat ring → secondary ball blast → weldering → heat treatment → calibration → pairing, saves human and material resources and time cost, realizes the cost efficiency in chain production, keeps away Exempted from vertical ring forging process it is various caused by quality stability difference risk, to improve the quality of chain products.With routine Compact chain is compared, and structural chain manufacture further simplifies process, has been captured the difficulties in quality control in vertical ring production, has been improved Production efficiency realizes the continual and steady qualification of the chain quality of production.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change It also should be regarded as the protection scope of the utility model into deformation.
