Method for cutting a cast strand or intermediate strip using shears

A method for cutting a cast strand or intermediate strip using shears. In order to facilitate improved rolling of the section having significantly reduced thickness, the method according has the following steps: a) bringing part of the completely solidified cast strand or intermediate strip in the conveying direction (F) of the cast strand or intermediate strip in front of the shears; b) placing a first blade of the shears onto the one surface of the cast strand or intermediate strip and placing a second blade of the shears onto the other surface of the cast strand or intermediate strip and performing a cut by carrying out a relative movement of the two blades, wherein at least one of the blades is in a pushed-forward position; c) upset forging or upset forging with stamping a wedge-shaped contour on the end of the cast strand.

Heat treatment apparatus for hot stamping and forming method using the same

A heat treatment apparatus for hot stamping includes a frame, and heating units provided to be vertically movable at both upper and lower sides of the frame and configured to heat a cold formed steel plate by electrifying the steel plate. Cooling units are provided to be vertically movable at centers of the upper and lower sides of the frame and are configured to cool the heated steel plate while pressurizing the steel plate from upper and lower sides.

Forged Wheel Trimming Die
20170291210 · 2017-10-12 · ·

An improved forged wheel trimming die, including a connecting rod, a lower die base lower plate, a bottom plate, a stripper guide pillar, a knockout rod, an ejector block, a lower die base stiffened plate, a lower die base upper plate, a lower die, a stripper plate, follow-up retainer plates, a shearing blade and a trimming rod. The improved forged wheel trimming die has the advantages that by adding two follow-up retainer plates to the stripper plate of the die, burrs of a forged wheel blank are constrained along the radial direction during the cutting, thereby avoiding breakage due to excessive deformation; in this way, the burrs can be protected from damage and knocked out successfully by the knockout rod after being cut off from the blank.

Clipping tool
09724749 · 2017-08-08 · ·

The present disclosure provides a clipping tool for clipping flash from a component e.g. a gas turbine aerofoil body. The clipping tool includes a riser having a support surface for supporting the component and a punch for gripping the component on the support surface such that the flash projects laterally from the riser and the punch. The clipping tool further comprises a tool body having a clipping aperture opening to a channel within the tool body. The channel is defined by a channel wall. The riser and the punch are translatable to shear the projecting flash from the gripped component. At least a portion of the channel wall within the tool body comprises a broaching surface having at least one projection, said projection reducing the cross sectional area of the channel to less than that of the clipping aperture.

Method for cutting metal plate, method for manufacturing metal product, and metal product
11247256 · 2022-02-15 ·

A method for cutting a metal plate, a method for manufacturing a metal product, and the metal product are provided which enable the formation of cracks to be suppressed even with application of external force and enable strength of a product to be increased. A method for cutting a metal plate 2 of one aspect according to the present invention includes a crushing step and a separation step. The crushing step is a step of crushing a removal target part 22 of the metal plate 2 in a thickness direction of the metal plate 2 by applying, to the removal target part 22, force from both sides in the thickness direction so as to deform the removal target part 22 into a thin-walled part 23. The separation step is a step of separating, after crushing step, the thin-walled part 23 from a body 21 of the metal plate 2.
