Description

Roller rod pin for reducing abrasion of square hole on roller rod transmission chain of press

Technical Field

The utility model relates to a continuous press technical field specifically discloses a reduce roller bar round pin of press roller bar drive chain top hole wearing and tearing.

Background

In the continuous pressing process of the artificial plate, the transmission process of the steel belt mainly depends on the action of a transmission chain and a roller rod to realize operation. In the operation process of the whole press, the roll shaft does not rotate continuously, and the roll shaft also runs along with the chain. When the roller pin is specifically arranged, a plurality of square clamping holes can be formed in each chain link of the transmission chain, then square blocks at the end parts of the roller pin (four ridge lines of the existing square blocks are provided with chamfers) are fixed in the square clamping holes, and then the other end of the roller pin is connected with the roller. But 90% of the roll bar pins will rotate in the square clamping holes due to the unreasonable arrangement of the square blocks on the roll bar pins, so that the square clamping holes are worn and deformed, and the deformation of the square clamping holes on the chain links can cause a series of problems. For example, abrasion deformation of the square clamping hole can cause the roller rod and the roller rod pin to fall off, thereby causing the roller rod to be overlapped and damaging the steel strip; in addition, the butterfly spring of the fixed roller rod pin is easy to wear out due to long-time slipping, the butterfly spring needs to be frequently replaced, and the frequent replacement of the butterfly spring can cause long-time shutdown of the continuous press, so that the normal operation of equipment cannot be ensured, and the production efficiency of the whole continuous press is reduced.

For example, the utility model with the patent number CN210196254U discloses a supporting pin shaft for a continuous press, which comprises a mandrel and a connecting piece, wherein the mandrel comprises an installation part and a connecting part, and the connecting piece is fixedly sleeved on the installation part and is used for being connected with a transmission chain of the continuous press; the connecting part is used for being inserted into an inner hole of the roller rod of the continuous press, and a wear-resistant sleeve is fixedly sleeved on the connecting part. The utility model discloses a square head on supporting pin axle just has the aforesaid not enough when setting up, refers to the attached figure 2 of this patent, and its square head just is provided with the chamfer with four crest lines departments of square head when the design, consequently will have the problem of wearing and tearing quad slit in the transmission process. Therefore, the roller pin capable of effectively reducing abrasion of the upper hole of the roller rod transmission chain of the press is designed aiming at the unreasonable design of the roller rod pin on the transmission chain of the existing continuous press, and the technical problem to be solved is solved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the design of roller round pin on continuous press drive chain unreasonable not enough that leads to chain link top to press the hole to be held by the easy wearing and tearing of wearing and tearing warp, design a roller round pin that can effectively reduce the wearing and tearing of press roller drive chain top hole.

The utility model discloses a realize through following technical scheme:

the utility model provides a reduce roller bar round pin of wearing and tearing of press roller bar drive chain top hole, includes the body of pin rod, the cladding has the copper bush of inlaying on the left periphery of the body of pin rod, the right-hand member portion of the body of pin rod is connected with the anticreep piece, is located inlay the square piece of fixedly connected with on the body of pin rod between copper bush and the anticreep piece, the cross sectional shape of square piece is the square.

As a further arrangement of the above scheme, the cross section of the square block is a square with a side length of 9.2mm, and the length of the square block is 12 mm; increasing the cross-section of the square blocks increases the torque resistance and reduces the possibility of rotation of the roller pin in the square clamping hole of the drive chain.
