[0031] Please refer to Figures 1 to 6 The utility model discloses a kind of stamping shaping devices for brush sheet, including a brush sheet assembly 1, the brush sheet assembly 1 includes the terminal 11 being connected into long strip whole and the brush sheet body 12 being set on the terminal 11, the brush sheet body 12 is V-shaped as a whole, and the V-shaped side of V-shaped is set on terminal 11, and the other side is inclined to hang in the air;It further includes a bracket 2 that can be erected on platform, a driving motor 3 being set on one end of bracket 2, a stamping column 4 being set on the output shaft of the driving motor 3, stamping baffle 5 being set on the other end of bracket 2, the first inclined stamping surface 41 that is matched with the V-shaped angle of the brush sheet body 12 is formed on the front end of the stamping column 4, and the stamping baffle 5 is protruded to form the second inclined stamping surface 51 matched with the first inclined stamping surface 41.
[0032] When producing, external conveying mechanism places the terminal 11 in the brush sheet assembly 1 between the stamping baffle 5 and stamping column 4, at this time the brush sheet body 12 is V-shaped as a whole, and the V-shaped side of V-shaped is set on terminal 11, and the other side is inclined to hang in the air, the driving motor 3 is started, drives the stamping column 4 and is pressed to stamping baffle 5, the first inclined stamping surface 41 of the stamping column 4 is pressed on one end of terminal 11, and continues to press in, so that the other side of terminal 11 is pressed on the second inclined stamping surface 51, continues to press in, until the terminal 11 is pressed and bent to the angle that the other end of brush sheet body 12 is inclined to hang in the air becomes parallel with motor, to facilitate subsequent process such as gluing, the whole process is high in degree of automation, high in accuracy, without manual work, save time and effort, guarantee production quality, reduce production cost, improve production efficiency.
[0033] For the specific structure of the terminal 11, such as Figure 3 And Figure 4As shown, the terminal 11 includes a connecting piece 111 connected in a long strip shape, and a connecting end 112 which is T-shaped as a whole and is deformed by the first inclined stamping surface 41 and the second inclined stamping surface 51, and the brush piece body 12 is arranged on the transverse portion of the connecting end 112. When the driving motor 3 drives the stamping column 4 to press in, one end of the longitudinal portion of the T-shaped connecting end 112 is pressed against the first inclined stamping surface 41, and the other end is pressed against the second inclined stamping surface 51, under the inclined guiding action of the first inclined stamping surface 41 and the second inclined stamping surface 51, the longitudinal portion of the T-shaped connecting end 112 is bent to make the end of the brush piece body 12 inclined and suspended to become an angle parallel to the motor, thereby facilitating subsequent processes such as glue sticking. By arranging the brush piece body 12 on the transverse portion of the connecting end 112, when the stamping column 4 is stamped, it will not directly contact the brush piece body 12, which effectively prevents damage to the brush piece body 12 while changing the angle of the brush piece body 12, thereby improving the yield.
[0034] In order to prevent the terminal 11 from being displaced during stamping and causing the stamping to be out of position, as shown in Figure 1 and Figure 2 and Figures 5 to 6 As shown, the stamping stop plate 5 is provided with a sliding limiting block 52 on both sides of one end of the stamping column 4, and a sliding limiting groove 53 is formed on the sliding limiting block 52 for placing the connecting piece 111, and the first inclined stamping surface 41 and the second inclined stamping surface 51 are located on the upper end of the sliding limiting groove 53. The connecting piece 111 is placed in the sliding limiting groove 53 by the external conveying mechanism, and the connecting piece 111 is pushed to move the brush piece assembly 1 as a whole, the connecting piece 111 is limited in the sliding limiting groove 53, and the connecting end 112 on the connecting piece 111 is inclined and stamped by the first inclined stamping surface 41 and the second inclined stamping surface 51 in the process, achieving the purpose of precise stamping, effectively improving the accuracy of the stamping and shaping device, and preventing the problem of stamping out of position. By locating the first inclined stamping surface 41 and the second inclined stamping surface 51 on the upper end of the sliding limiting groove 53, the connecting piece 111 is protected and limited in the sliding limiting groove 53 when the first inclined stamping surface 41 and the second inclined stamping surface 51 stamp, so that it will not be deformed by the first inclined stamping surface 41 and the second inclined stamping surface 51, which is beneficial to subsequent conveying and processing.
