Abstract
The present invention relates to a counterblow hammer with a plurality of unit heads, which belongs to a forging apparatus for metal forming, and is applicable to forming machining, and particularly to metal die forging machining. In the present invention, a plurality of unit heads are arranged on a frame of a counterblow hammer, so that the unit heads accomplish forming operation which is accomplished by a plurality of forging apparatuses at present. Each unit head accomplishes one machining procedure in forging machining, so that the number of the apparatuses is reduced, occupation area is reduced, workpiece transfer distance is shortened and heat dissipation loss and oxidization of a workpiece are reduced. Consequently, workpiece machining quality is improved and production cost is reduced.
Description
The present invention is a kind of metal forming forging equipment, and it is used for metal forming processing, particularly in the metal die forging processing.
Present existing forging equipment, no matter anvil block die hammer, flat-die hammer, or the counter-blow hammer of steel band interlock or fluid pressure linkage are arranged, on a frame, all have only a unit head (promptly to have only a cylinder driving head, or hydraulic-driven head, or electric driving head or other Mechanical Driven head).But in Forging Technology, usually require workpiece through repeatedly finally forming needed shape, i.e. multistation moulding after the distortion.In this case, for miniature workpiece, can adopt a plurality of type grooves are set on the module or the die holder of inserting solve.When processing work, workpiece is put into different type grooves respectively successively and is finished each time distortion.Because a plurality of type grooves are set on the module or the die holder of inserting, workpiece is placed on when hitting in some type grooves, and tup and mould will be subjected to eccentrically loaded effect, and this all is disadvantageous to tup guide and mould.Particularly big workpiece to projected area, as gear or other disk-shaped blank part, in the time of on a tup module or the die holder of inserting, can not arranging a plurality of type groove, or forging hammer can not bear because during eccentric load that many types of groove produced, the way of solution just has only with production line of several forging hammers compositions.For example, by the flat-die hammer base, 2 tons of hammer blockings, 3 tons or 5 tons of hammer finish-forgings, and then to bead cutter, cut edge.The equipment that this mode is used is many, and the plant area that takies is big, the distance that workpiece transmits, thereby will consider to dispel the heat workpiece temperature is reduced and the problems such as oxidation of workpiece in transmission.
The objective of the invention is to design a kind of forging equipment, it can need reach the purpose that reduces table of equipment number, minimizing floor space, shortening transmitting range, minimizing workpiece thermal loss and oxidation, improves the quality of products and reduce production costs two or two moulding tasks that above forging equipment just can be finished before finishing on the frame.
The present invention's employing two or more unit heads of dress on a counter-blow hammer frame achieve the above object.
The present invention as shown in Figure 1, it is made up of frame (1), unit head (2), elastic bearing (3) and outer leading truck (4).Special character of the present invention is: unit head (2) is two or more, and frame (1) gross mass is greater than more than 5 times of quality of unit head tup system, and having a unit head at least is the forging hammer tup.
Each unit head of the present invention can totally constitute a counter-blow hammer pair with frame, unit head remainder and other unit head: tup components of system as directed and frame or hammer body components of system as directed.Elastic bearing (3) is gone up because the quality of whole counter-blow hammer pair all is bearing in, in the outer leading truck (4).In the strike process, the tup hammer body constitutes an internal force system, the tup system descending, and the hammer body system is up under unit head and flexibly mounted reaction simultaneously, because hammer body system gross mass is much larger than the quality of tup system, so hammer body system uplink journey is less.For each unit head, all be equivalent to a forging equipment.Each unit head carries out work successively in turn, like this, originally needs can finish on an equipment with the work that two or two above equipment are finished.
The present invention is owing to be equipped with two or more unit heads on frame, therefore can not all unit heads can both be installed in the center of frame, and the unit head that has is setovered.When the biasing unit head is done when hitting tup and quickening to move downward, as long as outer leading truck (4) has suitable strength and stiffness, just can guarantee that tup does parallel relative motion with frame (1), and guarantee in the enough little unlikely hammered works that influences of the heavy curtain action spot that hits the moment hammer body.Owing to be counter-blow hammer, the frame of hammer body (1) is bearing in the outer guiding frame (4) by elastic bearing (4), the eccentric dynamic head is unsettled to hitting when hitting, and is very little to the basis vibrations like this, can not occur may beating situations such as oblique to the basis when common forging hammer biasing is hit.
When structure operating principle of the present invention guarantees that each unit head tup carries out accelerated motion, the internal force system that the tup hammer body is constituted all guarantees to constitute a counter-blow hammer form automatically, to many impacter forging hammer of interlock of steel band or fluid pressure linkage much simple in structure than adorning on a frame for it, is easy to realize.
The present invention also can be as shown in Figure 2, and it is by frame (1), unit head (2), elastic bearing (3), lead frame (4) and bead cutter (5) formed outward, and it is a pressure bead cutter unit head that a stature power head is wherein arranged.Can on same hammer, finish the desired side cut operation of forging like this.
The present invention is because be provided with two or more unit heads on a counter-blow hammer frame, the workpiece that can be before finishing on the hammer must just can finish at two or two above forging equipments is shaping work repeatedly, reach and reduce table of equipment number, minimizing floor space, shortening workpiece transmitting range, the radiation loss that reduces workpiece and oxidation, thereby improve workpiece quality and reduce production costs.
Structure of the present invention can adopt two beams, 4 pillar frames as shown in Figure 2, on putting the beams in place two forging hammer unit heads (2) can be set, and also has a pressure to cut edge (5) in addition, and putting the beams in place links to each other with underbeam (6) by 4 root posts (7).Upper beam, underbeam are linked to be whole frame (1) by column (7), and are installed in the outer leading truck (4), and elastic bearing (3) supports.Any tup quality m of unit head (2)
1With with respect to frame (1) part quality m
2Ratio should be less than 1: 5.Mass ratio is more little, and when tup was descending, frame (1) up stroke was just more little.Unit head among the present invention (2) can adopt electric liquid hammer unit head, and a plurality of unit heads can overlap HYDRAULIC CONTROL SYSTEM with one.Unit head can be provided with 3, and one is used for blocking, and one is used for finish-forging, and another is used for cutting edge.When tonnage demand was little, the blocking unit head can be a press power head also, and without peening hammer.
Fig. 1 is many unit heads counter-blow hammer structural representation.
Fig. 2 is that a power is arranged is many unit heads counter-blow hammer schematic diagram of pressure bead cutter.
Claims (2)
1, many unit heads counter-blow hammer, it is made up of frame (1), unit head (2), elastic bearing (3) and outer leading truck (4), it is characterized in that: unit head (2) is two or more, frame (1) gross mass is greater than more than 5 times of quality of the tup system of unit head (2), and having a unit head at least is the forging hammer tup.
2, many unit heads counter-blow hammer as claimed in claim 1 is characterized in that: it is a pressure bead cutter unit head that a unit head is wherein arranged.
