Description

Stamping jig for bending Technical Field The application relates to the field of industrial manufacturing, in particular to a stamping jig for bending. Background The stamping die is a special process device for processing materials into parts in cold stamping, and the principle is that the die arranged on a press machine is used for applying pressure to the materials so as to separate or plastically deform the materials. The related art discloses a spare part for rack, including being rectangular form material strip, offered the mounting hole on the material strip. During processing, a worker manually places the material strip at a rough position and then directly punches the material strip, so that a knife edge favorable for bending is formed on the material strip. Because the material strip is placed approximately by workers in the stamping process, the stamping position is inaccurate, so that the stamping position can be overlapped with the mounting hole, and obvious defects exist. Disclosure of Invention In order to improve accuracy of stamping positions of material strips, the application provides a stamping jig for bending. The application provides a stamping jig for bending, which adopts the following technical scheme: The utility model provides a punching press tool for bending, includes the tool body, it has the constant head tank that is used for placing the material strip of waiting to process to open on the tool body, the position of tool body relative constant head tank bottom is provided with and installs hole grafting complex reference column on the material strip. Through adopting above-mentioned technical scheme, the workman places the flitch in the constant head tank, and with reference column and mounting hole grafting cooperation to this is fixed a position the position of placing of flitch on the tool body, is favorable to improving the accuracy of the relative mounting hole punching press position of edge of a knife on the flitch. Optionally, the positioning groove is slightly wider than the strip. By adopting the technical scheme, the material strip is conveniently placed into the positioning groove by workers. Optionally, the mounting groove has been seted up to its inside to one side of tool body, the mounting groove is located the below of constant head tank and communicates with each other with it, two dwang that are parallel to each other have been arranged to the relative mounting groove rotation of tool body, circumference is provided with a plurality of lifters that are used for turning into the constant head tank and lifting material strip on the dwang, the position in the relative mounting groove of tool body still is provided with the driving motor of electricity connection in control system, driving motor's output shaft passes through sprocket and chain transmission in two dwang. Through adopting above-mentioned technical scheme, driving motor passes through sprocket and two dwang synchronous rotations of chain drive, and the dwang drives a plurality of liftout pieces and rotates, and a plurality of liftout pieces rotate into the constant head tank in proper order and with the liftout strip in the constant head tank ejecting to this has made things convenient for the workman to get the material.
