Abstract
The utility model discloses an upset blank lower die for a tie rod ball. The upset blank lower die is composed of a left upset head die block and a right upset head die block. A lower die left cavity and a lower die right cavity are formed in the left upset head die block and the right upset head die block respectively. After the left upset head die block and the right upset head die block undergo die assembling, a cavity which is composed of the lower die left cavity and the lower die right cavity is formed by sequential connecting of a cambered surface cavity, a conical cavity and a cylindrical cavity. By means of the upset blank lower die for the tie rod ball, a cylindrical bar can be inserted into the lower die conveniently, the bar can be controlled to be clamped in the lower die, and the cylindrical bar which is placed in the lower die can maintain good perpendicularity.
Description
Technical field
The utility model relates to a kind of mould of processing pull rod bulb, particularly relates to a kind of for forging the tie rod ball pier base counterdie of tie rod ball integral workblank.
Background technology
Tie rod ball is the conventional 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 can making tie rod ball, forging mold there is 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 at present mainly by cylindrical bar is forged and formed, 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, the structure of tie rod ball is made up of a bulb and rod body, an original bar needs forging roll to carry out roll forging to the end of barred body, bulb is carried out to preformed, carry out finish forge to final molding by forging press again.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 be higher than several times of forging presses, therefore improved the equipment cost of manufacturing enterprise, and that traditional pier mold exists blank is fixing insecure and perpendicularity is inadequate, while making to carry out rod head pier base, easily produces blank modification, bending problem, thereby cause formed product to have the material of lacking, imperfect, cause product rejection.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and is applicable to adopt forging machine to carry out tie rod ball head preformed, and perpendicularity is good, the tie rod ball pier base counterdie of fixing-stable.
The technical scheme in the invention for solving the above technical problem is: this tie rod ball pier base counterdie, by left heading module, right heading module composition, in left heading module and right heading module, be respectively arranged with counterdie levorotation chamber and the right die cavity of counterdie, after left heading module, right heading module matched moulds, the die cavity being made up of with the right die cavity of counterdie counterdie levorotation chamber is made up of the cambered surface chamber, conical cavity and the cylindrical cavity that are connected successively, the equal diameters of the diameter of cylindrical cavity and the cylindrical bar that will forge.
As preferably, in direction from top to bottom, the radius on the horizontal cross-section in described cambered surface chamber reduces gradually.
The utility model compared with prior art, has the following advantages and effect:
1) adopt the lower die structure of separate type, can facilitate cylindrical bar to insert counterdie, and can control bar is clamped
In counterdie, due to the equal diameters of diameter and the cylindrical bar of cylindrical cavity, the cylindrical bar being therefore placed in one can keep good perpendicularity;
2), by cambered surface chamber is set, can make bar end walk material, the head of moulding tie rod ball along the wall in cambered surface chamber.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1, the present embodiment tie rod ball pier base counterdie is made up of left heading module 1, right heading module 2, in left heading module 1 and right heading module 2, be respectively arranged with counterdie levorotation chamber and the right die cavity of counterdie, after left heading module 1, right heading module 2 matched moulds, the die cavity being made up of with the right die cavity of counterdie counterdie levorotation chamber is made up of the cambered surface chamber 3 being connected successively, conical cavity 4 and cylindrical cavity 5.The equal diameters of the diameter of cylindrical cavity 5 and the cylindrical bar that will forge.The horizontal cross-section of arc-shaped cavity 3, conical cavity 4 is circular, and constantly becomes large along with constantly increasing of the height on vertical direction, constantly becomes large structure thereby make arc-shaped cavity 3, conical cavity 4 be opening, facilitates bar to walk material along wall.
Above content described in this description is only to the explanation of the utility model example.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment; only otherwise depart from the content of the utility model description or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
Claims (2)
1. a tie rod ball pier base counterdie, it is characterized in that: by left heading module, right heading module composition, in left heading module and right heading module, be respectively arranged with counterdie levorotation chamber and the right die cavity of counterdie, after left heading module, right heading module matched moulds, the die cavity being made up of with the right die cavity of counterdie counterdie levorotation chamber is made up of the cambered surface chamber, conical cavity and the cylindrical cavity that are connected successively, the equal diameters of the diameter of cylindrical cavity and the cylindrical bar that will forge.
2. tie rod ball pier base counterdie according to claim 1, is characterized in that: in direction from top to bottom, the radius on the horizontal cross-section in described cambered surface chamber reduces gradually.
