Instrumental node for forming heads parts rod type

 

(57) Abstract:

Usage: metal forming, namely the manufacture of cold-formed tool for upsetting a large amount of heads parts rod type. The inventive instrumental node contains a floating punch, which is made under the palm rest of the stepped cavity. In most parts of the stepped cavity posted by spring and guide Bush. The end face of the bushing flange is pressed by a spring to a floating punch. The emphasis that is designed to transfer axial strengthening stalkivatel, installed inside the guide tube. When you move the focus remains alignment with stalkivatel. 1 Il.

The invention relates to the processing of metals by pressure and can be used in the manufacture of cold-formed tool, in particular for precipitation of a large amount of heads parts rod type.

Famous instrumental node for forming the heads of a large volume containing satellitel, floating punch, movable along the axis of the several springs, and the matrix [1]

A disadvantage of the known instrumental node is complex, bulky design. Longitudinal movement platen with a large outer diameter, that significantly increases the size and metal of all instrumental node.

The closest to the essential features is instrumental node for forming heads parts rod type, containing a spring interacting with the floating punch, focus and satellitel [2]

The disadvantage of this tool node is in a low resistance of its constituent parts. The emphasis in the process of landing moves freely in contact with the spring and has no direction on the cylindrical surface. If this is not ensured alignment of emphasis regarding stalkivatel. The axis of focus intersects with the axis of stalkivatel, the end face plane of focus becomes non-parallel to the plane of the end face of stalkivatel, there is a strong beating of end stops, leading to breakage stalkivatel. Broken particles stalkivatel, once in the spring, deform it turns.

The basis of the invention the task is to create convenient in use instrumental node for forming heads parts rod type with simple and robust design, ensuring a high quality of precipitation heads of large volume and predetermination node for forming heads parts rod type, contains a floating punch, satellitel, the stop and the spring located in the cavity of the floating punch, to prevent breakage of stalkivatel and failure of the spring it has a sleeve, the emphasis has the ability to move inside the sleeve along the axis while maintaining alignment with stalkivatel, and the plug has a stepped hole for accurate placement of the guide sleeve in the part of the cavity of larger diameter.

The use of such a tool site as possible with the prior forms of procurement for further planting in the open or closed die, and the settling of the final form of the head of a large volume.

The drawing shows a General view of the instrument node in a longitudinal incision in the final moulding of the head.

Instrumental node for forming the head of the blank 1 includes a floating punch 2, which is made under the palm rest step 3 cavity 4. In most parts of the stepped cavity posted by spring 5 and the guide sleeve 6, the end face of the flange which is pressed by a spring to a floating punch. Emphasis 3, for transmitting axial forces to stalkivatel 7, is installed inside the guide sleeve with the>At the initial moment of landing under the action of the spring 5 guide sleeve 6, which is in most part a stepped cavity 4 of the floating punch 2, is brought together with him in the extreme forward position. Then the floating punch 2 covers the workpiece 1. Upon further movement of satellitel 7 under the influence of the stop 3 brings the workpiece.

The use of instrumental node will significantly increase the reliability of cold-formed machine in work by preventing the possibility of breakage of stalkivatel spring and plunger.

Instrumental node for forming heads parts rod type, containing a floating punch, satellitel, the stop and the spring located in the cavity of the floating punch, characterized in that it is provided with a guide sleeve, and the emphasis placed can move inside the sleeve along its axis while maintaining alignment with stalkivatel when moving, while the cavity of the punch made speed for precise placement of the guide sleeve in the part of the cavity of larger diameter.

FIELD: plastic metal working, possibly manufacture of rod parts with heads.

SUBSTANCE: method comprises steps of placing portion of heated measure blank in movable die spring-loaded in axial direction and forming thickened portion. Die is mounted with possibility of motion in direction coinciding with that of punch motion. Additional step is realized for forming rod due to placing portion of blank in one-piece die with technological gap. Before forming thickened portion and rod, free heading of the whole blank is performed. Then die is moved and simultaneously first stage of heading thickened portion and step of rod forming by closed heading are realized. Closed heading is performed due to moving portion of blank in direction inverse relative to motion direction of punch and die. Then thickened portion is headed in fixed position of die.

EFFECT: possibility for making rod parts with thickened portion by means of simple technological tooling in high-speed automatic presses.

SUBSTANCE: for parts production cold-upsetting tool is used in the form of multi-position unit. Unit includes five positions and contains puncheons, thrusters, assembled matrixes and strippers. Assembled matrix in the fourth position is installed motionlessly and is equipped with reduction step at the insert. Stripper of the fourth position is arranged with the opening, in which spring-loaded puncheon is installed. Cut billet is subjected to setting and calibration with leveling of butt ends and formation of conical marks. By means of further billet setting head is created. Then opening is pressed out in the billet and its external diameter is reduced with formation of step. Reduction of diameter is carried out in motionless matrix with insert, which has reduction step. For that purpose billet is displaced until it thrusts stripper with spring-loaded puncheon with its butt-end. Puncheon is installed in billet pressed out opening. Later billet is displaced together with puncheon and stripper via reduction step of matrix. After that billet opening is interweaved.
