The automatic processing control system for sheet metal parts of building material equipment according to claim 1, wherein: the three-stage rotating seat (19) is integrally formed on the rotating bending seat (3), the three-stage rotating seat (19) is provided with the three-stage rotating hole (20), the three-stage rotating hole (20) and the one-stage rotating hole (13) are correspondingly arranged, the one-stage rotating shaft (7) penetrates through the three-stage rotating hole (20) and the one-stage rotating hole (13) to be installed, the three-stage rotating grooves (21) are formed in the two sides of the three-stage rotating seat (19) on the rotating bending seat (3), and when the rotating bending seat (3) is actually installed, the three-stage rotating seat (19) is rotationally arranged in the one-stage rotating groove (10), and the one-stage rotating seat (11) and the two-stage rotating seat (12) are rotationally arranged in the three-stage rotating groove (21).

4. The automatic processing control system for sheet metal parts of building material equipment according to claim 1, wherein: the utility model discloses a reset piece (5) comprises connecting seat (25), connecting rod (26), locating plate (27), reset spring (28) and one-level lantern ring (29) combination, set up on connecting seat (25) and four-level change the hole, its four-level change the hole and set up with two-level change hole (23) are corresponding, and two-level pivot (8) pass two-level change hole (23) and four-level change the hole and install, locating plate (27) and connecting rod (26) welded connection, reset spring (28), one-level lantern ring (29) movable sleeve are established on connecting rod (26), and when reset spring (28) are in reset state, its trailing flank that rotates bending seat (3) leans on with the trailing flank of one-level bending groove (9) mutually and sets up.

5. A control method of an automatic processing control system for sheet metal parts of building material equipment according to any one of claims 1 to 4, characterized by comprising the steps of: the control method of the automatic processing control system for the sheet metal parts of the building material equipment comprises the following steps:

step one: in the process of positioning the sheet metal part to be bent, a worker drives a hydraulic system to move in a return stroke manner, then a driving manipulator places the sheet metal part (51) to be bent on a fixed bending seat (2), and performs alignment on the sheet metal part (51) to be bent;

step two: in the primary bending process, the hydraulic system is driven to move, so that the sheet metal part (51) to be bent is forced through the primary bending body (31), and primary bending is formed;

step three: in the secondary bending process, the rotary bending seat (3) is forced by the primary bending body (31) so as to drive the rotary bending seat (3) to rotate, and the primary bending body (31) is embedded into the secondary bending groove (24), so that the sheet metal part (51) to be bent is secondarily bent, and a Z-shaped folded edge is formed;

step four: the return process, in which the hydraulic system moves in a return way, so that the return piece (5) drives the rotary bending seat (3) to return;

step five: and in the blanking process, the sheet metal part bent by the manipulator is taken down.
