Abstract

The utility model relates to the field of forging of shafts, particularly discloses a spring anvil which is applicable to the production of a large batch of shaft type forged pieces, comprises an upper anvil and a lower anvil, and is characterized in that an upright post is arranged on the lower anvil, a spring is sheathed on the upright post, and a through hole is formed in the position which corresponds to the upright post after the upper anvil is arranged in place. Compared with the prior art, the spring anvil has the benefits that the upper anvil can move up and down along the upright post during the forging process, so that the relative positions of the upper anvil and the lower anvil are fixed, the surface quality of the forged piece is greatly improved, the machining allowance is reduced, the spring can buffer the vibration and reduce the abrasion of the anvils, and the spring anvil is particularly applicable to the production of the large batch of the shaft type forged pieces and can greatly improve the working efficiency and achieve the purposes of saving working time and reducing consumption.

Description

A kind of spring hammering block

Technical field

The utility model relates to a class and forges the field, relates in particular to the spring hammering block of a kind of suitable production forged shaft in enormous quantities.

Background technology

The hammering block structure of using when the axle class is forged at present is upper anvil iron and lower anvil iron, correspondence is provided with arc groove on upper anvil iron and the lower anvil iron, upper anvil iron and lower anvil iron relative position are fixing, and upper anvil iron and lower anvil iron cooperate badly in the forging process, and the forging surplus is big, surface quality is poor, especially when producing forged shaft in enormous quantities, frequently align upper anvil iron and lower anvil iron, labor strength is big, operating efficiency is lower, can not satisfy the demand of production.

Summary of the invention

The purpose of this utility model provides a kind of spring hammering block, improves forging surface quality, reduces allowance, reduces labor strength, increases work efficiency.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of spring hammering block comprises upper anvil iron, lower anvil iron, it is characterized in that lower anvil iron is provided with column, is with spring on the column, and upper anvil iron back in place is provided with through hole with the column correspondence position.

Compared with prior art, the beneficial effects of the utility model are: upper anvil iron is in forging process, move up and down along column, the relative position of upper anvil iron and lower anvil iron is fixed, improve forging surface quality greatly, reduced allowance, the vibrations of spring available buffer reduce the wearing and tearing of anvil iron, are specially adapted to produce large batch of forged shaft, can significantly increase work efficiency, reach and save man-hour, reduce the purpose that consumes.

Description of drawings

Fig. 1 is the utility model example structure schematic diagram.

Among the figure: 1-upper anvil iron 2-lower anvil iron 3-column 4-spring 5-through hole

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:

See Fig. 1, a kind of spring hammering block example structure schematic diagram comprises upper anvil iron 1, lower anvil iron 2, and lower anvil iron 2 is provided with column 3, is with spring 4 on the column 3, and upper anvil iron 1 back in place is provided with through hole 5 with column 3 correspondence positions.

The utility model is fixed upper anvil iron 1, lower anvil iron 2 relative positions by two root posts 3, column 3 outside winding springs 4 come damping vibration, upper anvil iron 1 and lower anvil iron 2 are provided with accurate camber design, during forging blank is placed between upper anvil iron 1, the lower anvil iron 2, can forge ganoid circular shaft, column 3 slides in the through hole 5 of upper anvil iron 1, and the utility model can be forged the forging axle of multiple diameter.

The utility model is specially adapted to produce large batch of forged shaft, can significantly increase work efficiency, and reaches to save man-hour, reduces the purpose that consumes.

Claims

1. a spring hammering block comprises upper anvil iron, lower anvil iron, it is characterized in that lower anvil iron is provided with column, is with spring on the column, and upper anvil iron back in place is provided with through hole with the column correspondence position.
