Through research and analysis, the existing hammer head is relatively simple in structure, the whole stress of the hammer head is direct when the hammer is used for forging, no buffer area exists between the base body and the outer layer material, and the base body is easy to damage. In addition, in the forging process, because the temperature of the forging piece is higher, the heat dissipation of the existing hammer head structure is fast, the temperature is fast, the hammer head structure is influenced by high temperature, the thermal stress is large, the hammer head is easy to damage, and the service life of the hammer head structure is influenced. Therefore, the scheme aims to provide the precision forging machine hammer head structure with the composite structure, the high-temperature impact resistance of the hammer head is improved through the composite structure, the heat dissipation area is increased, the heat dissipation is accelerated, the influence of thermal stress on the hammer head is reduced, and the purpose of prolonging the service life of the hammer head is achieved; and the use of materials is correspondingly reduced, and the manufacturing cost is reduced.
The structure of the hammer head of the precision forging machine proposed by the present solution is described in detail below with reference to fig. 1 and 2. This scheme assembly quality mainly includes: a base body 1 and a wear-resistant layer 3 covering the impact surface of the base body 1. The abrasion-resistant layer 3 covers the impact surface of the base body 1, so that the impact force to the base body 1 in the forging process can be effectively reduced, the abrasion to the base body 1 is reduced, and the service life of the base body 1 is prolonged.
The wear-resistant layer 3 is required to have high strength and wear resistance as a structure which is first subjected to impact during forging, and therefore, a nickel-based alloy material having high strength and corrosion resistance at high temperature may be selected as the material of the wear-resistant layer 3. The wear-resistant layer 3 is tightly attached to the impact surface of the base body 1, so that the wear-resistant layer 3 is prevented from generating relative displacement with the base body 1 in the impact process.
In the scheme, in order to enable the wear-resistant layer 3 and the base body 1 to be combined more tightly, the transition layer 2 is further added between the wear-resistant layer 3 and the base body 1, and the wear-resistant layer 3 is tightly attached to the impact surface of the base body 1 through the bonding force of the transition layer 2. In one embodiment, the transition layer 2 is made of a nickel-based material, and the nickel-based material has good fusion with the base body 1 and the wear-resistant layer 3, so that the adhesion between the two is improved.
In this scheme, still be provided with supplementary fixed knot structure between transition layer 2 and wearing layer 3, avoid transition layer 2 and wearing layer 3 to produce through supplementary fixed knot structure and peel off the problem. In one embodiment, the auxiliary fixing structure may be a structure in which the protrusion structure 6 and the groove 5 are matched. Specifically, as shown in fig. 2, a groove 5 is formed in the upper surface of the transition layer 2, and a protruding structure 6 is added to the lower surface of the wear-resistant layer 3; the positions and the number of the grooves 5 and the raised structures 6 are matched. Utilize recess 5 and protruding structure 6's spacing effect, further prevent that wearing layer 3 from taking place to remove along the horizontal direction, utilize the joining force that forms behind recess 5 and the protruding structure 6 combination, further prevent that wearing layer 3 and transition layer 2 from producing the peeling problem. In addition, the protruding structures 6 can share the radial pressure borne by the wear-resistant layer 3 in the forging process to a certain extent, so that the impact force borne by the base body 1 is greatly reduced.
In one embodiment, the raised structure 6 may be a structure integral with the wear layer 3; the convex structure 6 can be designed into a long strip-shaped structure which is matched with the long strip-shaped groove 5 arranged on the transition layer 2; in another embodiment, the raised structure 6 may be a structure integral with the wear layer 3; the raised structures 6 may be designed as a plurality of square/rectangular bump structures arranged in an array on the wear layer 3, which match with the square/rectangular recesses 5 provided on the transition layer 2.
In one embodiment, the material of the transition layer 2 in a molten state may be firstly overlaid on the impact surface of the base body 1 by means of overlay welding, then a plurality of grooves 5 are formed on the upper surface (i.e. the surface in contact with the wear-resistant layer 3) of the transition layer 2 at equal intervals, and then the material of the wear-resistant layer 3 in a molten state is overlaid on the transition layer 2 with the grooves 5 by means of overlay welding, so as to form a three-layer composite hammer head structure.
In this scheme, consider that the tup can produce a large amount of heats at high-speed forging and pressing in-process, this kind of heat can cause the influence to the intensity of tup. From this, at the position that base member 1 is close to transition layer 2, set up a plurality of through-holes 4 along the direction that the perpendicular to tup is strikeed, utilize through-hole 4 to take away high-speed forging and pressing in-process, the heat that the tup produced reduces the influence of high temperature to tup intensity.
It should be noted that, the local strength of the substrate 1 is affected by the holes themselves formed in the substrate 1, and therefore, the number of the holes is not too large, and is generally 3 to 5. Preferably, three 10mm circular through holes 4 can be selectively opened.
In the forging and pressing process, the hammer head structure wear-resistant layer 3 is firstly subjected to impact force, and the abrasion of the impact force to the base body 1 can be effectively reduced through the buffering of the wear-resistant layer 3 and the protruding structure 6, and meanwhile, the abrasion degree of the base body 1 is reduced. In the forging process, the base body 1 can generate a large amount of heat due to high-speed work, and at the moment, the heat can be quickly dissipated through the through holes 4 in the base body 1, so that the service life of the hammer head structure is prolonged, and the maintenance cost is reduced.
The scheme structurally improves the stress and heat dissipation characteristics of the hammer head structure, thereby prolonging the service life. Through utilizing composite construction to improve tup atress condition, increase heat radiating area and accelerate tup radiating rate and reduce the thermal stress influence, reduce the material simultaneously and use, the effectual tup life that has prolonged the cost is reduced.
The present solution is further illustrated by the following examples.
This embodiment discloses a precision forging machine tup structure, this structure optimizes tup atress characteristic through the three-layer composite construction and the supplementary fixed knot structure of base member 1, transition layer 2 and wearing layer 3, and meanwhile, increases heat radiating rate through increasing heat dissipation through-hole 4 increase heat radiating area, reaches extension tup life's purpose. In particular, the amount of the solvent to be used,
as shown in fig. 1 and 2, the hammer head structure of the precision forging machine includes: a base body 1, a transition layer 2 and a wear-resistant layer 3. In this embodiment, the substrate 1 is made of die steel, and the wear-resistant layer 3 is made of a nickel-based alloy having high strength and corrosion resistance at high temperature. Since the nickel-based alloy has poor fusion with the die steel, the transition layer 2 is required to be connected as a bonding agent. The material of the transition layer 2 is a nickel-based material which has better fusion with the base body 1 and the wear-resistant layer 3, the material of the transition layer 2 is cladded on the base body 1 in a surfacing mode, and then the wear-resistant layer 3 is cladded in the surfacing mode.
In this embodiment, transition layer 2 upper surface increases recess 5, and recess 5 quantity can be according to the corresponding increase of tup size or reduction to the corresponding protruding structure 6 that forms of size and quantity of recess 5 is matchd to wearing layer 3 lower surface. The composite structure of the concave-convex connection can enable the transition layer 2 and the wear-resistant layer 3 to be connected better, and avoids the peeling phenomenon of the transition layer 2 and the wear-resistant layer. The arrangement of the protruding structure 6 increases the stress volume of the wear-resistant layer 3 to a certain extent, so that the wear-resistant layer and the transition layer 2 form better connectivity, and the performance of bearing impact pressure of the wear-resistant layer 3 can be further improved. In addition, the convex structure 6 can also well absorb part of radial pressure during forging and pressing, so that the impact force borne by the substrate 1 is greatly reduced.
In this embodiment, the circular through holes 4 with a diameter of about 10mm are added at the position on the substrate 1 close to the transition layer 2, the number of the through holes 4 is not too large, and a certain distance is kept between the through holes 4, so that the strength of the substrate 1 is not affected by the through holes 4. The through hole 4 structure forms the negative pressure at the high-speed forging and pressing in-process of tup, drives the air and flows, and the heat is taken away to the air that flows for the tup heat dissipation, reduces the influence of thermal stress to the tup. The appropriate number and hole spacing in turn avoid an influence on the strength of the hammer head base body 1 itself.
In conclusion, the transition layer 2 and the wear-resistant layer 3 and the auxiliary fixing structure between the transition layer 2 and the wear-resistant layer 3 are additionally arranged on the base body 1, so that the impact force on the base body 1 during forging and pressing can be greatly reduced; through increase through-hole 4 on base member 1 for the radiating rate of tup structure, thereby the life of extension tup structure reduces the maintenance cost.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
