| The invention relates to a method for producing balls, especially for ball pivots, and to a ball element for two-part ball pivots. The balls according to the invention are produced by cold extrusion and subsequent grinding, using a micro-alloy carbon-manganese steel. The use of micro-alloy carbon-manganese steel allows to obtain balls having excellent strength and hardness already due to the cold shaping. It is not necessary to use a tempering step as required for the production of generic balls, which allows the use of less expensive materials, thereby considerably reducing production costs. The invention allows for a simple and inexpensive method for producing balls for two-part ball pivots while maintaining and/or increasing surface and material quality as well as strength and wear resistance. As a result, the complexity of the method is reduced and the problem of dents which can occur on the ball surfaces during tempering is removed. | ||||||

| PURPOSE: To improve an inverse press for obtaining surer and more reliability in motion and driving of its tool supporting body by effecting force on the tool supporting body to the direction inverse to the direction of press working through a piston surface by compressed air. CONSTITUTION: A tool supporting body 1 is coaxially surrounded by an annular piston 9 which is freely movable inside a cylinder 10 of a bearing 2. The external shape of the tool supporting body 1 is formed in a round shaft elongated longer than the piston 9 and having coaxial recessed part 11, and the piston 9 is shiftable to a limited distance with respect to the tool supporting body 1. Compressed air is put into the cylinder chamber 10 to move the piston 9 to separate a punch, by which the tool supporting body 1 is energized in the direction of a carriage 5. Consequently, an air spring formed of the piston 9 and the cylinder 10 is kept, so that all the elements of the device are pressed with each other. | ||||||

| PURPOSE: To manufacture ball stock for a corrosion and wear resistant valve through die forging by manufacturing a clad bar having a corrosion and wear resistant alloy layer round a core of corrosion resistant metal, forming a sphere having recessed places at both poles from this bar by hot forging and removing the part between the recessed places. CONSTITUTION: Rolling material of cylindrical corrosion metal is arranged at the center of a cylindrical metal and its peripheral space is filled with corrosion and wear resistant alloy powder. This is hot-extruded and cut to manufacture a forging stock 9 of clad bar having a corrosion and wear resistant alloy layer round a core of corrosion resistant metal. This stock 9 is hot-forged by press dies 11A, 11B and pins 15A, 15B to form a sphere having recessed places 24 at both poles. Then, a wall 25 between the recessed places 24 is removed. In this way, it is possible to efficiently produce the valve ball having a surface coating layer forged solidly to the core. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE:To heighten density of an outer layer and improve a mechanical property by forging a composite roll outer layer of which is made of a hard alloy and an inner layer is made of a soft alloy by heating the outer layer to a proper temperature for forging and keeping the inner layer at a lower temperature. CONSTITUTION:A composite roll is formed by cold forming a powder metal (high speed steel) on the outer periphery of a round bar. Outer periphery is enclosed with ordinary steel to prevent deformation at the time of forging, and forged by heating. At this time, the forging machine is heated rapidly by induction heating. The outer layer is heated to the proper temperature for forging and the inner layer is maintained at the low temperature. By this way, the time of forging is shortened, and the deterioration of the mechanical property of the inner layer of the roll is improved remarkably. | ||||||

| PURPOSE:To improve strength of a welded metal to a shaft part and wear resistance and mechanical strength of the shaft part by forming a groove on the surface of the shaft part at the time of cold forging to form a roller component and making spray welding of a different material on the surface of the shaft. CONSTITUTION:This method possessing a die 10 which regulates an external diameter of a roller component and a punch 11 which regulates an internal diameter of the roller component forges a roller component 30 in the cold condition through a press deformation of a blank 20 in a space between the die 10 and the punch 11 by pressing the punch 11 in an arrow direction forcibly. Then, a groove 40A is formed on the surface of a shaft part 40 by forming protruded lines 10A on the surface 10' which regulates the shaft part 40 especially at the die. And then, a spray welding layer 50 is formed by making spray welding of a different material on the surface of the shaft part 40. | ||||||
