After positioning, press the start button, the clamping cylinder 96 controls the clamping plate 99 to press down to the placement plate 60, and the adjusting cylinder 63 controls the folding plate 61 to fold to complete the folding process of the plate.

[0062] Based on the same inventive concept, embodiments of the present invention provide a stamping method, including: Step 1: Collect stamping instructions, and obtain sheet metal information based on the stamping instructions. The sheet metal information includes thickness information and material information. A stamping command is an instruction issued by the operator when stamping is required. The stamping command can be issued by the operator pressing a button and then turning on the power.

[0063] The information about the board material refers to the information about the board material itself. The image of the board material is identified by a camera through image recognition technology and compared with a preset board material database to output the corresponding board material information. The board material information includes thickness information and material information. Thickness information refers to the thickness of the board material, and material information refers to the material of the board material, such as iron, alloy, copper, etc.

[0064] The camera model is selected by the staff based on the actual situation and will not be elaborated here. The board database refers to the database formed after the staff inputs the different board information corresponding to different board images determined in advance through experiments.

[0065] Step 2: Determine the folding force and downward pressure based on thickness and material information; Folding force refers to the folding force of the sheet metal adjusting cylinder 63. The folding force can be determined by querying the folding database. The folding database is a database of folding forces obtained by inputting thickness and material information. The folding database is determined in advance by staff through experiments, showing different folding forces corresponding to different thickness and material information.

[0066] The downward pressure refers to the force exerted by the plate adjusting cylinder 63. The downward pressure can be determined by querying the downward pressure database. The downward pressure database is a database of downward pressure obtained by inputting thickness and material information. The downward pressure database is determined in advance by the staff through experiments, and the different downward pressure corresponding to different thickness and material information is different.

[0067] Step 3: Based on the downward pressure, control the pressing cylinder 96 to press the plate and control the adjusting cylinder 63 to fold the plate according to the folding force.

[0068] After the pressing plate is pressed by the pressing cylinder 96 based on the downward pressure, the plate is folded by the control and adjustment cylinder 63 with the folding force.

[0069] A stamping method further includes: Step 4: Obtain the shape of the stamped sheet The shape of the board refers to the shape of the board after it has been folded. The shape of the board can be obtained by capturing images with a camera.

[0070] Step 5: Determine the stamping result based on the comparison between the sheet metal shape and the preset reference shape. The stamping result includes qualified and unqualified. The reference shape refers to the required shape of the sheet material. The reference shape is obtained by the staff through manual input in advance. The reference shape is compared with the sheet material shape to determine the stamping result. The stamping result is whether the sheet material is qualified or unqualified. If the sheet material shape does not match the reference shape, it is unqualified. If the reference shape matches the sheet material shape, it is qualified.

[0071] Step 50: Issue a discharge notification based on the material's pass / fail status; Material discharge reminder refers to prompting staff to retrieve materials. The material discharge reminder can be issued by an alarm, which is selected by the staff based on the actual situation and will not be elaborated here.

[0072] Step 51: Based on the non-compliance, calculate the angle difference between the board shape and the preset reference shape; When the board material is substandard, calculate the angle difference. The angle difference is determined by subtracting the angle of the reference shape from the angle of the board material shape. For example, if the angle of the board material shape is 120 degrees and the angle of the reference shape is 89 degrees, then 120-89=31 degrees.

[0073] Step 510: Combine the angle difference, thickness information, and material information to match the corresponding adjustment parameters from the preset calculation data; the adjustment parameters include the downward adjustment parameters and the folding adjustment parameters; The adjustment parameters refer to the parameters that need to be adjusted for the adjusting cylinder 63. These parameters can be obtained from a parameter database. The parameter database is a set of adjustment parameters obtained after detecting defects by substituting angle differences, thickness information, and material information. The database consists of different adjustment parameters corresponding to different angle differences, thickness information, and material information, determined in advance by the staff through experiments. The adjustment parameters include the downward pressure adjustment parameters and the folding adjustment parameters, which are the adjustment parameters required for the pressing cylinder 96 and the adjusting cylinder 63, respectively.

[0074] Step 511: Adjust the downward pressure based on the downward pressure adjustment parameter, adjust the folding force based on the folding adjustment parameter, and repeat the judgment of the stamping result until it is qualified.

[0075] The downward pressure is adjusted based on the downward pressure parameter, and the folding force is adjusted based on the folding adjustment parameter. The downward pressure is repeated, and the result is judged until the downward pressure is qualified.
