Abstract

The utility model relates to a lower anvil structure of a hydraulic hammer. The lower anvil structure comprises an anvil body, wherein lifting holes are formed in the two sides of the anvil body respectively; the lower part of the anvil body extends outwards to form a dovetail block; an outer opening and an inner opening of the dovetail block are staggered and form an interval a; an included angle beta is formed between an oblique surface formed by connecting the outer opening with the inner opening and a longitudinal vertical surface. The lower anvil structure is simple in structure and convenient to manufacture; the included angle is formed between the oblique surface formed by connecting the outer end surface with the inner end surface and the longitudinal vertical surface by dislocating the outer end surface and the inner end surface of the dovetail groove, so that part of vibration and compression force of the hydraulic hammer relative to a forge piece step during forging and pressing can be eliminated, the service life of a lower anvil seat is prolonged, the problems of cracking, wear and shifting as well as folding, step unevenness and the like caused during forging and pressing of shaft forge pieces are prevented, and the working efficiency of forging and pressing equipment is improved; in addition, the forging quality of the forge pieces is greatly improved and the production efficiency is improved.

Description

Anvil structure under a kind of hydraulic hammer

Technical field

The utility model relates to field of machining, relates in particular to anvil structure under a kind of hydraulic hammer.

Background technology

At present, in forging forging and stamping process, the mould of forging and stamping need to be placed in to forging equipment below and carry out conducting forging processing, 5 tons of hydraulic hammers are all generally to forge and press by the lower anvil block of hydraulic hammer band, need the object of forging and stamping to be placed on base, forge and press by anvil block reading matter body under hydraulic hammer, due to stressed large, lower anvil block and base can wear and tear, cracking and displacement, produce deformation and skew, thereby affect the operating efficiency of forging equipment, and utilize the product that existing lower anvil block forges out easily to produce folding, especially for forged shaft, its shaft shoulder step out-of-flatness.

Utility model content

The applicant, for above-mentioned existing issue, is studied improvement, and anvil structure under a kind of hydraulic hammer is provided, thereby.

The technical scheme that the utility model adopts is as follows:

Anvil structure under a kind of hydraulic hammer, comprise anvil body, the both sides that are positioned at described anvil body have had repeated hole, the bottom that the is positioned at described anvil body formation dovetails that stretches out, spacing a is arranged and forms in the external port of described dovetails and inner port dislocation, forms angle β between the inclined-plane that described external port and inner port are connected to form and longitudinal vertical plane.

Its further technical scheme is:

Described spacing a is 0.5～1mm;

Described angle β is 2 ° ± 1 °.

The beneficial effects of the utility model are as follows:

The utility model is simple in structure, easily manufactured, by dovetail groove outer face and inner face dislocation are arranged, make the inclined-plane of outer face and inner face connection and longitudinally between vertical line, form angle, thereby eliminate hydraulic hammer in a part of forging and stamping process and, with respect to the vibration of forging step and receipts power, in the service life of having improved time anvil block, prevent cracking, wearing and tearing and skew, and forged shaft is in problems such as folding, the step out-of-flatnesses of the generation in whens forging and stamping, has improved the operating efficiency of forging equipment.The forging quality that has greatly improved forging, has improved production efficiency.Accompanying drawing explanation

Fig. 1 is front view of the present utility model.

Fig. 2 is the upward view of this Fig. 1.

Fig. 3 is the structural representation of dovetails in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 and Figure 2, anvil structure under a kind of hydraulic hammer, comprise anvil body 1, the both sides that are positioned at anvil body 1 have lifting 101, the bottom that is positioned at anvil body 1 stretches out and forms dovetails 103, spacing a is arranged and forms in the external port of dovetails 103 and inner port dislocation, forms angle β between the inclined-plane that external port and inner port are connected to form and longitudinal vertical plane.Described spacing a is 0.5～1mm.Described angle β is 2 ° ± 1 °.As shown in Figure 1, Figure 3, the first hypotenuse 104 of dovetails 103 outer faces parallel with the second hypotenuse 105 of inner face but dislocation arrange, in Fig. 3, dotted line is expressed as datum level, and solid line is expressed as actual face, in actual forging and stamping process, due to this outer face and inner face dislocation layout, thereby eliminating hydraulic hammer in a part of forging and stamping process vibrates and receipts power with respect to forging step, improve the service life of time anvil block, prevented cracking, wearing and tearing and skew, improved the operating efficiency of forging equipment.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
