Description

It is applicable to process the noise reducing type forging hammer of bearing forging

Technical field

This utility model belongs to forging process equipment technical field, particularly relates to a kind of fall being applicable to process bearing forging Make an uproar swage.

Background technology

Forging equipment refers in forging processing for the plant equipment shaped and separate.Forging equipment includes shaping Forging hammer, punching machine, hydraulic press, fly press and horizontal forging and upsetting machine, and forging manipulator, uncoiler, arbor press, cutter Etc. auxiliary equipment.Wherein, forging hammer is to utilize the drive mechanism such as air pressure or hydraulic pressure to make to fall part, including piston, hammer stem, tup, Upper anvils etc. produce motion and accumulate kinetic energy, are applied to forging in the extremely short time, are allowed to obtain plastic deformation ability, complete various forging The metal forming machinery of pressure technique.Existing forging hammer also exists many deficiencies, such as, poor stability in use process, forging hammer body under Not having guide frame during falling, shift phenomenon easily occur, this is mainly due to producing the biggest hitting power in forging hammer dropping process, And the reverse impact power that tup is produced by forging is the biggest, irregularly forge face when tup clashes into forging, then reverse impact power is not Straight up, the most still there is the power of a skew, forging hammer body so can be caused to produce bigger biasing force, make Obtain forging hammer body and shift phenomenon easily occurs.

In order to solve the problem that prior art exists, people have carried out long-term exploration, it is proposed that solution miscellaneous Scheme.Such as, Chinese patent literature discloses a kind of forging hammer [application number: 201520088191.1], including frame and hammer stem, institute State and in frame, be provided with chute；Described hammer stem is slidably connected in chute；Described frame is fixed with fastening with the intersection of chute Bar；Axle sleeve free to rotate it is arranged with on described anchorage bar；The notch position phase of described axle sleeve position and chute horizontal direction Corresponding.

Above-mentioned scheme cooperates to realize the purpose that hammer stem guides by hammer stem and axle sleeve, but due to hammer stem only court One side outside chute contacts with axle sleeve, and it remains the side corresponding with chute and does not have guide frame, and hammer stem used The problem that still there will be left and right skew in journey, although left and right skew can be overcome by directly being contacted with chute by hammer stem Problem, but hammer stem necessarily causes between two kinds frictional force to increase after directly contacting with chute, affect the decrease speed of hammer stem with Impulsive force；Chopping block vibrations are big；The noise produced is big；Cannot be carried out garbage collection.

Summary of the invention

The purpose of this utility model is for the problems referred to above, it is provided that a kind of design is the most reasonable, can carry out multiple to forging hammer What direction guided is applicable to process the noise reducing type forging hammer of bearing forging.

For reaching above-mentioned purpose, this utility model have employed following technical proposal: is originally applicable to process the fall of bearing forging Making an uproar swage, including being arranged on base and domed support body, described support body is vertically provided with forging hammer passage, described Forging hammer passage in slide and be provided with forging hammer connecting rod, and slide and be arranged in support body upper end in described forging hammer connecting rod one end, another End connection has forging hammer body, and described forging hammer body cross section is the polygonized structure that circumference has some corners, described forging hammer It is provided with between body outer circumferential and support body and forging hammer body circumference can be carried out spacing thus produce skew when preventing forging hammer body from sliding Forging hammer guide frame, described base is provided with the chopping block body being positioned at below forging hammer body, and described base is provided with and can cover at Transparent cover on whole chopping block body, the diameter of the upper end diameter of described transparent cover to lower end becomes larger, and described is saturating Bright cover body upper end offers and forges window for what forging hammer body passed, is provided with at least side and chopping block body in transparent cover outer circumferential The operation window that sidepiece is corresponding, and described transparent cover is split-type structural, and described transparent cover is by two resistance to height The arc block that adiabator is made is spliced, and is provided with can be mutually located by each arc block removable between described arc block Unload structure, and described chopping block body includes the split type chopping block base of rectangular-blocklike, described split type chopping block base upper end center It is movably equipped with outer circumferential in being provided with the tapered channel with inner conical surface, and described tapered channel to have and match with inner conical surface The taper anvil of male cone (strobilus masculinus), be provided with when taper anvil is acted on downwards between described taper anvil and split type chopping block base Taper anvil can be played buffering during power and taper anvil can be made when the down force that taper anvil is subject to disappears slowly multiple The elastic damping resetting structure of position.The setting of transparent cover, not only contributes to the collection of waste material, and can make an uproar forging generation Sound is isolated.
