Description

A kind of conveying worm shell ring and processing method thereof

Technical field

The present invention relates to a kind of conveying worm shell ring and processing method thereof, belong to technical field of conveying machinery.

Background technology

For conveying worm, for preventing the abrasion of shell ring itself, typically generally can adopt in the internal wear-resisting layer covering of shell ring In two ways: one is to be fastened by bolt, this mounting means needs to hole on shell ring, then uses bolt tight Gu, its workload is big, material waste is big；Two is directly to be welded together with shell ring by wearing layer periphery, and this welding manner is made Become wearing layer height not on same circumference, during work, make concentrated wear serious.

Summary of the invention

The technical problem to be solved is the defect existed for prior art, it is provided that a kind of conveying worm is used Shell ring and processing method thereof.

For solving this technical problem, the invention provides a kind of conveying worm shell ring, including shell ring and wearing layer, Described shell ring is formed by upper half shell ring and lower half shell ring welding, and described upper half shell ring is consistent with the external diameter of lower half shell ring, lower half cylinder The barrel of joint is thinner than the barrel of upper half shell ring；Described wearing layer is made up of the wear rib that width is the same, and described wear rib uniformly welds Being connected on the inwall of lower half shell ring, lower half shell ring is all covered by wear rib.

Described upper half shell ring and lower half shell ring use the steel plate of different-thickness to roll and form.

The processing method that present invention also offers a kind of conveying worm shell ring, comprises the steps:

1) use sheet metal to roll and make lower half shell ring；

2) use steel plate to roll and make upper half shell ring；

3) high-abrasive material is processed into width consistent, the wear rib that length is isometric with shell ring；

4) wear rib is uniformly paved with lower half shell ring internal layer, on welding lower half shell ring；

5) by step 4) lower half shell ring and upper half shell ring weld together, make conveying worm shell ring.

Beneficial effect: wearing layer is divided into the wear rib that quantity is certain by the present invention, and directly welds with lower half shell ring respectively, Avoid the projection problem of wearing layer.Present configuration is simple, it is easy to processes and installs.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

In figure: 1 upper half shell ring, 2 lower half shell rings, 3 wear ribs.

Detailed description of the invention

Below in conjunction with the accompanying drawings and the present invention is specifically described by embodiment.

Fig. 1 show the structural representation of the present invention.

The present invention includes shell ring and wearing layer.

Described shell ring is formed by upper half shell ring 1 and lower half shell ring 2 welding, described upper half shell ring 1 and the external diameter of lower half shell ring 2 Unanimously, the barrel of lower half shell ring 2 is thinner than the barrel of upper half shell ring 1.

Described upper half shell ring 1 and lower half shell ring 2 use the steel plate of different-thickness to roll and form.

Described wearing layer 3 is made up of the wear rib that width is the same, and described wear rib uniform welding is at the inwall of lower half shell ring 2 On, lower half shell ring 2 is all covered by wear rib.

Described wear rib material uses wear-resistant composite board 6+5 (being made up of basic unit and wearing layer).

The Wall-Thickness Difference of described upper half shell ring 1 and lower half shell ring 2 and wearing layer 3 consistency of thickness.

The processing method of the present invention, comprises the steps:

1) use sheet metal to roll and make lower half shell ring 2；

2) use steel plate to roll and make upper half shell ring 1；

3) high-abrasive material is processed into width consistent, the wear rib that length is isometric with shell ring；

4) by wear rib all be paved with lower half shell ring 2 internal layer, welding lower half shell ring 2 on；

5) by step 4) lower half shell ring 2 and upper half shell ring 1 weld together, make conveying worm shell ring.

Wearing layer is divided into the wear rib that quantity is certain by the present invention, and directly weld with lower half shell ring respectively, it is to avoid resistance to The projection problem of mill layer.Solve use on the bolt big workload that causes of fastening and wearing layer circumference in prior art concavo-convex The concentrated wear caused is serious, protection and the shell ring of material contact portion.Present configuration is simple, it is easy to processes and installs.

The embodiment above of the present invention, is merely illustrative, and is not only, all within the scope of the present invention or equivalent this Change in the range of invention is all surrounded by the present invention.
