Abstract
The invention discloses an initially-upsetting mold for a tie-rod-ball blank. The initially-upsetting mold is formed by an upper mold body and a lower mold body. The upper mold body is formed by an installation base and an upper mold block, wherein the upper mold block is fixed to the installation base. The lower mold body is formed by a lower mold table top, a left upsetting head mold block, a right upsetting head mold block and an oil cylinder, wherein the left upsetting head mold block is fixed to the lower mold table top, the right upsetting head mold block is installed on the lower mold table top in a sliding mode, and the bottom face of the upper mold block is of a plane structure. According to the initially-upsetting mold for the tie-rod-ball blank, a bar can be controlled to be clamped inside the lower mold body, the good perpendicularity of the cylindrical bar can be kept, and deformation during initial forging and pressing is even.
Description
Technical field
The present invention relates to a kind of pull bar forging mold, particularly the first pier mould of a kind of tie rod ball blank.
Background technology
Tie rod ball is the indispensable parts on automobile, because tie rod ball is in the process of the power of transmission, is bearing very high impact inertia force and bending force, and these all require tie rod ball to need certain intensity, toughness and fatigue proof performance.Because forging mold can be so that tie rod ball has the precision of the physical dimension that approaches final products most, and can improve its interior tissue, obtain better mechanical property, so the moulding of tie rod ball is mainly by cylindrical bar is forged and formed at present, the structure of tie rod ball consists of a bulb and rod body, in the process of actual production, because the distortion of once forging is out of contior too large, therefore a cylindrical bar often needs multiple tracks forging process ability final molding, an original bar needs forging roll to carry out roll forging to the end of barred body, bulb is carried out to preformed, by forging press, carry out finish forge to final molding again.Yet this just need to require manufacturing enterprise, there is forging press and forging roll simultaneously, just can carry out the processing and forming of tie rod ball, the price of the forging roll on market will, higher than several times of forging presses, therefore improve the equipment cost of manufacturing enterprise.If while using forging press and traditional pier mold to carry out pier base, it is fixing insecure and perpendicularity is inadequate that traditional pier mold exists blank, while making to carry out head pier base, easily produce the problem of blank modification, bending, thereby cause formed product to have the material of lacking, imperfect, cause product rejection.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of reasonable in design, can utilize forging equipment to carry out tie rod ball forging, and the first pier mould of the tie rod ball blank that can control perpendicularity in forging process well and make blank fixing-stable.
The present invention addresses the above problem adopted technical scheme: this tie rod ball blank is pier mould just, by upper die and lower die, formed, it is characterized in that: described patrix consists of mount pad and upper module, described upper module is fixed on mount pad, described counterdie is by counterdie table top, left heading module, right heading module and oil cylinder form, described left heading module is fixed on counterdie table top, right heading module is slidably mounted on counterdie table top, the right heading module of described hydraulic oil cylinder driving is done linear slide on counterdie table top, in left heading module and right heading module, be respectively arranged with counterdie levorotation chamber and the right die cavity of counterdie, the shape of counterdie levorotation chamber and the right die cavity of counterdie, structure is identical, left heading module, after right heading module matched moulds, the die cavity consisting of with the right die cavity of counterdie counterdie levorotation chamber is by the arc-shaped cavity being connected successively, conical cavity and cylindrical cavity form, the bottom surface of described upper module adopts planar structure.The equal diameters of the diameter of cylindrical cavity and cylindrical bar to be processed.
As preferably, in right heading module of the present invention, be provided with sliding panel, on counterdie table top, be fixed with two pier nose moulded boards, between pier nose moulded board and counterdie table top, form the chute sliding for sliding panel, sliding panel is slidably mounted in chute, one end of sliding panel is provided with oil cylinder the first Connection Block, is provided with oil cylinder and connects the second joint chair on counterdie table top, and the two ends of oil cylinder connect respectively oil cylinder the first Connection Block and oil cylinder connects the second joint chair.
The present invention compared with prior art, has the following advantages and effect:
1) adopt oil cylinder to control the folding between right heading module and left heading module, can facilitate cylindrical bar to insert counterdie, and can control bar is clamped in the cylindrical cavity of counterdie, the equal diameters of the diameter of cylindrical cavity and cylindrical bar to be processed, the cylindrical bar being therefore placed in one can keep good perpendicularity;
2) by arc-shaped cavity is set, when forging, can be so that material be easily walked along the wall of arc-shaped cavity in bar end.
3) upper module adopts planar structure, this structure be applicable to cylindrical bar in counterdie for the first time forging and stamping in, the bottom surface of the upper module of planar structure, can and the end face of cylindrical bar between form very large contact area, thereby even forging pressure is provided, and when making the first forging and stamping of cylindrical bar, distortion evenly.
