Description
Technical field
The utility model relates to Warm Extrusion Technology field, particularly relates to a kind of block forging mould for cross axle Warm Extrusion.
Background technology
Along with developing rapidly of auto industry, the demand of automobile cross axle also gets more and more.At present, in prior art, generally adopt open die forging, impressing forging to process cross axle, open die forging, impressing forging can produce overlap, increases manufacturing cost, and in production in enormous quantities, the waste of material phenomenon produced because of overlap is very important.So for the shortcoming of open die forging, impressing forging, in recent years, occurred block forging, block forging technology is a kind of precision forging technology developed rapidly in recent years.This technical characterstic is that first matched moulds recycling drift carries out extrusion molding to the blank in impression, blank is in have the three-dimensional compressive stress state of good plasticity by mold clamping force and extruding force, can the part of once-forming complicated shape.Compared with traditional open type Forging Technology, production cost is low, stock utilization is high.But the Product Precision that block forging processes is general, and therefore, occurred again warm-extrusion forming technology, warm-extrusion forming technology is a kind of Plastic Forming new technology grown up on cold extrusion Plastic Forming basis in recent years.Warm-extrusion forming technique possesses low, the easy shaping of extrusion stress and the features such as possibility is little of oxidation, decarburization, a kind of efficient, high-quality, low consumed precision processing technology, can make the part of shape matching complexity, and the part made there are good surface quality and dimensional accuracy.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, and the advantage of comprehensive block forging and Warm Extrusion forming technique, proposes a kind of Warm Extrusion block forging mould for processing cross axle.
The utility model is achieved by the following technical solution: a kind of block forging mould for cross axle Warm Extrusion, comprise die shoe (9), upper bolster (11), lower push rod (17), upper ejector pin (10), wherein:
Float and be provided with lower bolster (8) in described die shoe (9) upper end, big spring (16) is provided with between die shoe (9) and lower bolster (8), on described lower bolster (8), medium position place is provided with lower cavity die (15), the side of lower bolster (8) is provided with the hook (6) for pinning cope match-plate pattern (12), opposite side is provided with pilot hole, be equipped with guide pillar (14) in pilot hole, guide pillar (14) is through upper bolster (11), cope match-plate pattern (12).
Described upper bolster (11) lower end is fixedly installed cope match-plate pattern (12) by screw (4), cope match-plate pattern (12) is provided with upper cavity die (13), during work, upper cavity die (13) and lower cavity die (15) coordinate, and form confined space.
Further, described hook (6) is articulated with on lower bolster (8), and hook (6) is provided with the offside of lower bolster (8) hinged place the little spring (7) rotated for auxiliary hook (6).
Further, for ease of assembling, the straight pin (5) for locating between described cope match-plate pattern (12) and upper cavity die (13), is also provided with.
Further, be protection cope match-plate pattern (12), the position that described hook (6) contacts with cope match-plate pattern (12) is also provided with cushion block (3).
Further, pressure plare (2) is also provided with between described upper bolster (11) and cope match-plate pattern (12).
Further, described upper ejector pin (10) and cope match-plate pattern (12), be also provided with floating spring between lower push rod (17) and lower bolster (8).
Owing to have employed said structure, the utility model compared with prior art, there is following beneficial effect: this mould is in the Warm Extrusion forging of cross axle, no longer produce overlap, greatly save cost, improve production efficiency, and the cross axle made there are good surface quality and dimensional accuracy, there is significant economic benefit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of block forging mould for cross axle Warm Extrusion, comprise die shoe 9, upper bolster 11, lower push rod 17, upper ejector pin 10, wherein: float and be provided with lower bolster 8 in described die shoe 9 upper end, big spring 16 is provided with between die shoe 9 and lower bolster 8, on described lower bolster 8, medium position place is provided with lower cavity die 15, the side of lower bolster 8 is provided with the hook 6 for pinning cope match-plate pattern 12, opposite side is provided with pilot hole, be equipped with guide pillar 14 in pilot hole, guide pillar 14 is through upper bolster 11, cope match-plate pattern 12; Described upper bolster 11 lower end is fixedly installed cope match-plate pattern 12 by screw 4, cope match-plate pattern 12 is provided with upper cavity die 13, and during work, upper cavity die 13 and lower cavity die 15 coordinate, and forms confined space.
Course of work principle of the present utility model is, blank is placed in the counterbore of lower cavity die 15, blank is located naturally by vestibule wall, cope match-plate pattern 12 is descending with press ram, and the guide pillar 14 of lower bolster 8 imports the guide pin bushing on cope match-plate pattern 12, and upper cavity die 13 is involutory with lower cavity die 15, formed and close die cavity, hook 6 inwardly turns an angle under little spring 7 acts on simultaneously, hooks cushion block 3, upper cavity die 13, lower cavity die 15 is pinned.After this, cope match-plate pattern 12 continues descending, and drive lower cavity die 13, lower bolster 8 float downwards together with hook 6, and big spring 16 is compressed, and the blank in counterbore is clamp-oned die cavity by lower push rod 17.When cope match-plate pattern 12 reaches bottom dead centre, deformable metal is full of die cavity, and extruding terminates.Cope match-plate pattern 12 lifts, not yet open at incipient stage hook 6, lower bolster 8, lower cavity die 13 and hook 6 float with cope match-plate pattern 12, when hook 6 afterbody is blocked, along with lower bolster 8 continues to float, hook 6 is opened, and separately, cope match-plate pattern 12 and lower bolster 8 rise to respective extreme position for upper cavity die 13, lower cavity die 15.Cross axle is stayed in upper cavity die 13 or lower cavity die 15, when staying in upper cavity die 13, drives upper ejector pin 10 to eject by forcing press head 1; When staying upper cavity die 13, eject with reason lower push rod 17.
In the present embodiment, before Warm Extrusion, blowtorch need be adopted to carry out preheating to die working portion, preheat temperature about 300 DEG C, in Warm Extrusion process, mold temperature will reach 500 ~ 600 DEG C, running hours hardness sharply declines, process may be caused not continue, in Warm Extrusion process, need to adopt sprayer unit cooling fluid to be sprayed to die working portion cool, temperature is reduced.
The utility model, in the Warm Extrusion forging of cross axle, no longer produces overlap, greatly saved cost, improve production efficiency, and the cross axle made has good surface quality and dimensional accuracy, have significant economic benefit.
