A method of manufacturing a metal component includes performing a test stamping process on a test sheet metal blank, generating a strain map of the test sheet metal blank for the test stamping process, generating a lubrication program based on the strain map, applying lubrication to the sheet metal according to the lubrication program, and stamping the sheet metal to form the metal component. The lubrication program is configured to control a lubrication system to apply lubrication to sheet metal in a non-uniform distribution across the sheet metal. The non-uniform distribution correlates to the strain map.

A press line includes: a first press machine configured to shear an outer peripheral portion of a metal material by using a blanking die; a second press machine configured to form a press-formed component by performing press forming on the sheared metal material with a forming die; a preprocessing device configured to perform predetermined preprocessing on the metal material; a measurement instrument configured to measure information on a material characteristic value of the metal material before the press forming; and a control device configured to calculate a press forming condition for inhibiting occurrence of a forming defect for a metal material to be formed by inputting the material characteristic value of the metal material to be formed and manufacturing information to a machine learning model.

A method of joining strip-shaped sheets includes a support step of placing a support member in contact with a reverse feed direction end of a strip-shaped sheet fed to a pressing machine and a feed direction end of a new strip-shaped sheet, and a joining step of joining the new strip-shaped sheet to the strip-shaped sheet by attaching a tape on the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet, wherein in the joining step, the tape is attached from a side opposite the support member with the support member placed in contact with the reverse feed direction end of the strip-shaped sheet and the feed direction end of the new strip-shaped sheet. The problem of the variation in welding quality encountered when welding thin and wide strip-shaped sheets together is resolved and the strip-shaped sheet is fed smoothly.

A sheet metal strip is directed from a supply coil into a unitized system including a frame supporting a feed roll driven by a variable speed motor. The strip is directed upwardly from the feed roll between vertical guide rods to produce an inverted U-shaped vertical loop detected by sensors connected to control the feed roll motor. A servo driven index roll receives and advances the strip into tooling within a reciprocating press. Vibration insulators support the frame from a base stand mounted on air casters which provide for quickly removing the system from the press. The axial length of each roll is less than the width of the strip and engages only a center portion of the strip. A second index roll driven by a servo motor may be used on the press to provide push/pull advancement of the strip through the press.

A die for a blanking device, a blanking accumulation device, and a blanking method are provided with which blanks having a length that is greater than a width of a metal coil can be blanked and accumulated in an accumulating device (piler), with a target orientation. The method includes a continuous metal coil that is received and is subjected to blanking using a die. The die has a shearing portion for blanking a blank. The shearing portion has an inclination angle relative to a line direction in which the blank is discharged. The die further includes, downstream of the shearing portion, a discharge means including an orientation changing means for changing an orientation of the blank from an inclined state having a first inclination angle, at the time at which shearing is complete, to a second larger inclination angle.

A secondary battery electrode plate manufacturing apparatus includes: a distance measurement sensor installed in a die and configured to output a sensor output value; a parallelism calculation unit configured to convert the sensor output value into a distance value to determine parallelism of the die; and a punch insert amount calculation unit configured to calculate a punch insert amount by using the converted distance value.

A robot-assisted sheet metal bending loading and unloading path planning method based on an SVSDF is provided. The method includes the following steps: Step 1, constructing a two-dimensional pixel coordinate system; Step 2, obtaining an initial motion trajectory of loading and unloading a sheet metal part; Step 3, calculating path safety; Step 4, calculating a path cost; Step 5, calculating a fitness value of the initial motion trajectory of loading and unloading the sheet metal part; Step 6, optimizing the path cost and the path safety to obtain an optimal motion trajectory of loading and unloading the sheet metal part; and Step 7, through derivation of a bending loading and unloading motion relationship, transforming a motion trajectory of loading and unloading a workpiece itself into a motion trajectory of each axis of a bending robot.
