Initially-upsetting mold for tie-rod-ball blank
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. 1. A rod end blank initial block die ;, by the upper die (1) and a lower die (2) form, characterized in that the upper die (1) comprises a mounting seat (11) and the upper module (12) form, the upper module (12) is fixed on the mounting base (11) is, the lower die (2) consists of a lower table surface (21), left heading module (22), right heading module (23) and cylinder (24) form, the states the left heading module (22) is fixed to the lower-die table (21) is, right heading module (23) is slidably mounted on lower die table (21) is, the oil cylinder (24) driving right heading module (23) in the lower die table (21) linearly sliding on, left heading module (22) and right heading module (23) are respectively arranged on the right and the lower die left die space mold die, and lower die left die space the shape of the die cavity right , have the same structure, left heading module (22), right heading module (23) closing the rear, and from the lower mould left die spaceright cavity formed by successively connecting the cavity of the arc-shaped chamber (25), conical cavity (26) and the cylindrical cavity (27) form, a cylindrical cavity (27) and the forging to the diameter of the cylindrical bar is equal to the diameter of the, the upper module (12) with the bottom surface of the planar structure. 2. The according to claim 1 at the beginning of the rod end blank block die ;, characterized in that the head module states right ferrule at the butt-end (23) is provided with a sliding plate (28), the lower table surface (21) is fixed with two hitting platen (29), and reliably hitting (29) and a lower die table (21) for the sliding plate is formed between (28) sliding the sliding slot, the sliding plate (28) is slidably mounted on the chute, the sliding plate (28) one end of the connecting seat is provided with an oil cylinder 1st (210), the lower table surface (21) is provided with a cylinder connecting 2nd base (211), cylinder (24) are respectively connected with the cylinder the two ends of the connecting seat is 1st (210) and cylinder connecting 2nd seat (211).
