Abstract
The utility model relates to an upsetting tool for forging press which is used for the heat processing of metal forgings in metallurgy industry. The upsetting tool for forging press is characterized in that the upsetting tool is an 'anomalous metal forging': the top is a work stake (the plane dimension is consistent with the upsetting requirements of a steel ingot) in a plane cake shape, the tail end is a clamp handgrip with the dimension matched with the clamp of a manipulator for forging, and the crank connected with the work stake and the clamp handgrip is an arc bending connector. When working: the steel ingot after entering a heating furnace for heating and heat preservation first completes the 'handgrip press' of the steel ingot under the functions of the upper plane stake and the lower plane stake of the forging press; then the lower plane stake is changed into an upsetting lower stake, and the steel ingot is arranged on the upsetting lower stake inversely; finally the clamp handgrip is clamped via the clamp of the manipulator for forging to cause the work stake to enter between the steel ingot and the upper plane stake to accomplish 'upset'. The upsetting tool for forging press has the characteristics of simple structure and easy fabrication, with convenient usage, and realizes 'heat processing in one heating number' for the technologies of 'handgrip press and upset'; precious energy resource is economized, production flow is accelerated, and production cost is reduced.
Description
Technical field
The utility model relates to the hot-working of metallurgy industry metal material, refers in particular to be used for the hot worked device of metal forging.
Background technology
The forging press forging and pressing just adopt forging press that steel ingot is forged into qualified metal forging products, and it is the hot worked common mode of metallurgy industry metal material.The metal forging products can relate to shapes such as roundwood, square bar, flat bar, axle class part, cake spare, ring.
When the metal forging products was produced, pressure handle (extruded a pincers handle at ingot head, is convenient to the pincers handle that forging manipulator can clamp steel ingot, make steel ingot thermal processing distortion between the upper and lower work flat anvil of forging press.), jumping-up (the one, increase the forging ratio of steel ingot, guarantee the metallurgical quality of forging products; The 2nd, guarantee the appearance and size of finished product.) two operations that are absolutely necessary, also be first, second operation.
At present, common " pressure handle, jumping-up " technology is " the inferior hot-working of two fire ": (1) steel ingot advances heating furnace one fire heating, insulation, and the work anvil of forging press is that (go up anvil is the rectangle flat anvil to flat anvil, is commonly called as flat anvil; Following anvil also is the rectangle flat anvil, is commonly called as down flat anvil; Last flat anvil and following flat anvil size coupling), the steel ingot that goes out heating furnace is finished " pressure handle " thermal processing distortion of ingot head under the effect of last flat anvil, following flat anvil; (2) steel ingot after " pressure handle " advances heating furnace two fire heating, insulation, and the work anvil of while forging press makes the jumping-up anvil into by flat anvil, and (anvil is circular or foursquare flat anvil on the jumping-up, and size is greater than last flat anvil; Anvil is annular flat anvil (drain cap just) under the jumping-up, and the pincers that the center hole size of drain cap is slightly larger than ingot head are diameter dimension, under the jumping-up thickness of anvil greater than the pincers of ingot head length dimension; Anvil size coupling under anvil, the jumping-up on the jumping-up), the anvil swap time is lacked (1～3 minute) under the jumping-up, the swap time of anvil long (about 10～15 minutes) on the jumping-up, " pressure handle " steel ingot that goes out heating furnace is finished the thermal processing distortion of steel ingot " jumping-up " under the effect of jumping-up anvil.
To existing " two fire time hot worked pressure handles, jumping-up " industrial analysis research, we draw: the work anvil swap time (" go up flat anvil, flat anvil " down → " on the jumping-up under anvil, the jumping-up anvil ") that shortens forging press, especially the swap time of anvil on the jumping-up, " pressure handle, jumping-up " technology can carry out in " fire " fully." a fire time hot worked pressure handle, jumping-up " technology, the energy that not only can saves valuable, also speed production flow process greatly.
Summary of the invention
The utility model designs a kind of forging press jumping-up instrument, be used for " jumping-up forging " after the metal forging products " steel ingot pressure handle ", need not to change anvil on the jumping-up, under jumping-up anvil 7, under the effect of flat anvil 5, jumping-up instrument, realize " the fire time hot-working forging and pressing " of " pressure handle, jumping-up " technology, the energy of saves valuable has been accelerated production procedure, has reduced production cost.
A kind of forging press jumping-up instrument that the utility model provides is characterized in that: the jumping-up instrument is one " abnormity metal forging ", and the top is a work anvil 4, and afterbody is that pincers are 2, with work anvil 4, clamp 2 that what link to each other is crank 3; Work anvil 4 is " plane pie ", and (D is too little, can not reach the requirement of steel ingot jumping-up for planar dimension D=1.4d～1.7d; D is too big, increases cost of manufacture.), d is steel ingot 6 cross sectional dimensions, and thickness h 1 (unit is mm)=0.09G～0.12G (h1 is too thin, during steel ingot 6 jumping-ups, and work anvil 4 easy deformation, cracking, service life is short; H1 is too thick, not only increases the cost of manufacture of jumping-up instrument, also is subjected to the locus restriction of forging press working depth.), G is the nominal pressure (unit is a ton) of forging press; " cylindrical " pincers mate 2 size and forging manipulator clamp 1 size (be convenient to forging manipulator clamp 1 can clamp cylinders clamp 2), pincers are in parallel position to 2 cylindrical center axis with work anvil 4, central axis is h2 with the height fall of work anvil 4 lower planes, H3-H2≤h2≤H1-H2-h1, H1 is the maximum height on flat anvil 5 and ground on the forging press, H2 is the height on forging manipulator clamp 1 horizontal axis extreme higher position and ground, and H3 is the height that is upside down in 6 afterbodys of the steel ingot on the anvil 7 and ground under the jumping-up; The crank 3 of arc-shaped bend is a connector, and two ends link 2 with work anvil 4, pincers respectively; Above-mentioned in conjunction with constituting the utility model.
The shape of work anvil 4 is circular, square.
The material of jumping-up instrument is a steel alloy, and preferably (the structural steel cost is lower, and high-carbon steel is easy to crack for low carbon-structural steel.)。
Compared with prior art, the utlity model has following advantage:
(1) modern design, simple in structure;
(2) make easily, easy to operate;
(3) avoid the transposing of anvil on the jumping-up, striven for the valuable hot-working time;
(4) realized " one fire time forging and pressing " of " pressure handle, jumping-up " technology, reduced production cost.
