Example two:

the embodiment of the application also discloses a shaping process. The shaping process comprises the following steps:

step S1: a workpiece is arranged on a detection table 11, a flatness detector 12 moves on a horizontal plane through the operation of a first motor 13 and a second motor 15, a signal of the detection position of the workpiece is formed through the detection of the rotation angles of the first motor 13 and the second motor 15, and the detection of the rotation angles of the first motor 13 and the second motor 15 is realized by an encoder. Meanwhile, the flatness detector 12 detects flatness data of a corresponding position of the workpiece in a scanning manner. And transmitting the generated data signals of the workpiece detection position and the flatness to a control system and carrying out data correspondence.

Step S2: the third driving source 45 drives the shaping heads 3 to move, so that the shaping heads 3 are located at positions away from each other in advance. The workpiece is moved from the inspection table 11 to the jig 2, the jig 2 clamps the workpiece by operation, and the driving source three 45 drives the corresponding shaping head 3 to move so that the edge of the workpiece enters each through opening 313.

Referring to fig. 5, the first driving source 42 drives the first carriage 41 to slide, and in the process, the second driving source 44 is controlled to move, so that the second carriage 43 is displaced in the vertical direction of the plate surface of the workpiece, and the second carriage 43 drives the shaping head 3 to move. The data signal to be corrected obtained in step S1 controls the moving width of the second carriage 43, specifically as follows: in the control system, the workpiece detection position and flatness data obtained in step S1 are used as raw data, the displacement amount of the corresponding position of the workpiece to be corrected is calculated through a function, the data is converted into an electric signal and then the second driving source 44 is controlled to operate, so that the height of the shaping head 3 is increased or decreased, and the shaping head 3 deforms the workpiece to the trend of high flatness by pressing the surface of the workpiece plate, thereby finishing shaping. The first carriage 41 does not stop moving during the shaping process.

If the flatness detected in step S1 is convex upward, the movement of the shaping head 3 at the corresponding position in step S2 is downward movement, and the shaping head 3 contacts the workpiece by the upper roller 312 or the shaping block 321. If the flatness detected at step S1 is concave, the movement of the shaping head 3 at the corresponding position is upward movement at step S2, and the shaping head 3 contacts the workpiece by the lower roller 312 or the shaping block 321.

In step S2, the movement trajectory of the shaping head 3 when shaping the workpiece is parabolic, taking the shaping head 3 moving upward for shaping, the specific implementation method is as follows: the first carriage 41 is driven by the first driving source 42 to move horizontally at a constant speed, the second carriage 43 is lifted at a certain initial speed at the shaping position, then the lifting speed is linearly reduced, and after the lifting speed is zero, the descending speed is linearly raised, so that the moving track of the shaping head 3 relative to the rack 1 is in a parabolic shape, and a servo motor serving as the second driving source 44 can complete the action. Generally, the cross section of the workpiece before shaping is parabolic, when the moving track of the shaping head 3 is parabolic, the deformation of the workpiece can be offset, the deformation which should be elastically rebounded after the workpiece is shaped can be balanced by increasing the displacement of the shaping head 3, a good shaping effect can be achieved on the workpiece, and the shaping can be completed to a great extent at one time.

After the step S2 is completed, the workpiece is returned to the flatness detecting apparatus 12 for flatness detection, and then the steps S1 and S2 are repeatedly performed until the flatness of the workpiece meets the requirements. The position of the workpiece is moved by a manipulator (not shown in the figure), which sucks the middle part of the workpiece by an electromagnet and then drives the workpiece to move.
