The invention relates to the technical field of pulverizer blades, in particular to pulverizer blade forging equipment which comprises a supporting seat, a supporting rod is fixedly connected to the surface of the supporting seat, a top plate is fixedly connected to the top of the supporting rod, a lower die is fixedly connected to the surface of the supporting seat, and a forging hammer is arranged at the top of the lower die. The forging hammer is located at the bottom of the top plate. An impact mechanism, a pushing mechanism and a jacking mechanism are arranged on the surface of the top plate; the impact mechanism comprises a rotating disc and a first connecting plate. A first rotating rod drives a rotating disc to rotate, a first connecting block and a movable rod rotate along with the rotating disc, a first movable groove is formed, the movable rod can drive a first connecting plate to vertically move on the inner side of a top plate, and then lifting of a forging hammer can be achieved; and through the lifting effect of the forging hammer, a workpiece on the lower die can be conveniently impacted, so that the crushing machine blade can be forged.

The invention belongs to the technical field of cutter manufacturing, and particularly relates to a manufacturing device for producing a metal cutter. The material guiding assembly is of an open structure, a blank processing assembly is arranged on the inner wall of the material guiding assembly, a metal tool blank is movably clamped to the blank processing assembly and horizontally arranged, and the output end of a third air cylinder drives a conical pressing head to move downwards. The device is used for carrying out press-fit forming on a cutter blank while moving an incandescent cutter out of a furnace, and the two sets of conical pressing heads can be in rolling fit connection with the two sides of the top of the metal cutter blank in the process of being matched with the metal cutter blank to horizontally move, so that the cutter blank is formed at the top of the pressed metal cutter blank; and the forming efficiency of the blank in the manufacturing process of the metal cutter is improved.

A method for manufacturing a toothed rotary component (10) having a thickened tooth flank, comprising the steps of: a) manufacturing teeth (3) extending along a plane and uniformly distributed around a blank (1) made of sheet metal material, wherein each tooth (3) has lateral tooth flanks (6) spaced apart from one another by notches (4) distributed around the blank (1); b) deforming at least one tooth flank (6) to manufacture at least one lobe (5), wherein at least one lobe protrudes from the plane of the blank (1), is made of the same material, and protrudes diagonally or vertically upward from the plane of the blank (1); and c) deforming the lobe (5) protruding in the direction of the plane of the blank (1) into a thickened portion (9) of the tooth (3) in the area of ​​the original tooth flank (6).

A method for producing a toothed and rotating component (10) with thickened tooth flanks (6, 12), comprising the following steps: a) producing teeth (3) distributed uniformly on the periphery of a blank (1) which extends along one plane and is made from sheet metal material, wherein the individual teeth (3) have lateral tooth flanks (6) which are spaced apart from one another by cut-outs (4) distributed on the periphery of the blank (1); b) deforming at least one tooth flank (6) to produce at least one lobe (5) which projects out of the plane of the blank (1), is made from the same material and projects obliquely or perpendicularly upwards from the plane of the blank (1); c) deforming the projecting lobe (5) in the direction of the plane of the blank (1) to the thickened portion (9) of the teeth (3) in the region of the original tooth flanks (6).

The utility model belongs to the technical field of hammer forging dies, and particularly relates to a die for producing a high-strength explosion-proof hammer, which comprises a fixed table, a support column is fixedly mounted at the top of the fixed table, a butt joint column is fixedly mounted at the top of the support column, and a connecting plate is slidably mounted on the outer surface of the butt joint column. A lower die is fixedly installed at the top of the fixing table, an upper die is fixedly installed at the bottom of the connecting plate, and a cylindrical hammer groove, a conical hammer groove and a hammer head notch are formed in the top of the lower die and the bottom of the upper die. The cylindrical hammer groove, the conical hammer groove and the hammerhead notch which correspond to each other are formed in the middle of the upper die and the middle of the lower die, so that a worker can place heated hammerhead blanks into the cylindrical hammer groove, the conical hammer groove and the hammerhead notch for forging through a clamp, and hammerheads of different shapes at the two ends of the hammerhead can be forged at a time; the forging time of the hammer head is greatly prolonged, and blank cooling caused by hammer head transferring is avoided.

A forged hammer head (14) formed in a forging process comprises a forged hammer face (20) at one end (22) of the head; a forged hammer claw (36) at an end (23) of the head opposite the face; and a forged side nail puller (45) disposed between the face and the claw. A method for forming a hammer head (14) comprises sequentially placing a blank in a series of cooperating forging dies, and sequentially shaping the blank in the forging dies into a hammer head (14) with a hammer claw (36), a hammer face (20) and a side nail puller (45) disposed between the face and the claw. The side nail puller is configured to engage and pull a nail from a workpiece. The side nail puller comprises a side wall (47) and a notch (49) formed in the side wall. A tool parting line (TPL) of the forging process does not intersect the notch.
