[0025] Combined with Figure 1-7 , the specific implementation mode of the present invention is described as follows:

A plurality of sheet material conveying rollers 32 are provided and are evenly distributed on the sheet material conveying frame 31 in parallel with each other. A heat preservation cover is provided above the sheet material conveying frame 31 to keep the high-temperature blank sheet material 100 entering the sheet material conveying frame 31 warm.

[0028] The oxide scale removal mechanism is composed of two upper and lower brush rollers 36 arranged at the end of the sheet conveyor frame 31, and the brush rollers 36 are both provided with steel wire bristles 361. An oxide scale outlet 37 is provided on the sheet conveyor frame 31 in front of the brush roller 36 of the oxide scale removal mechanism, and a waste vehicle transport guide rail 371 is provided below the oxide scale outlet 37, and an oxide scale recovery waste vehicle 372 is provided on the waste vehicle transport guide rail 371. Two symmetrical auxiliary feed arc baffles 35 are provided on the sheet conveyor frame 31 in front of the oxide scale outlet 37.

[0029] Among them, there are several centering auxiliary mechanisms and cylinder beating centering mechanisms that are evenly distributed on the sheet conveyor frame 31. The centering auxiliary mechanism is composed of two centering auxiliary roller devices 33 symmetrically arranged on both sides of the sheet conveyor frame 31. The centering auxiliary roller device 33 includes a first fixed seat 331, a support suspension 332, and an auxiliary roller 333. The first fixed seat 331 is installed on the sheet conveyor frame 31, and the auxiliary roller 333 is installed at the front end of the support suspension 332. The rear end of the support suspension 332 is fixed to the first fixed seat 331 by two or more spiral telescopic springs 334. A limiting bolt is set on the axis of the spiral telescopic spring 334. One end of the limiting bolt is fixed to the support suspension 332, and the other end is suspended in the spiral telescopic spring 334. The cylinder beating centering mechanism is composed of two centering and pushing devices 34 symmetrically arranged on both sides of the sheet material conveying frame 31; the center pushing device 34 includes a cylinder fixing seat 341 and a centering and pushing bracket 342. The cylinder fixing seat 341 is installed on the sheet material conveying frame 31, and the centering and pushing bracket 342 is installed on the telescopic rod 343 of the telescopic cylinder arranged on the cylinder fixing seat 341. The high-temperature blank sheet 100 is corrected in position by the two centering and pushing devices 34 symmetrically arranged on both sides of the sheet material conveying frame 31 and the centering auxiliary roller device 33.

[0030] The sheet length measuring mechanism is composed of an end measuring component 38 and a front positioning component 39. The end measuring component 38 is arranged on the sheet conveying frame 31 behind the brush roller 36, and the front positioning component 39 is arranged on the press 4 at the front end of the sheet conveying frame 31. The front positioning component 39 includes a positioning baffle 391, a rotating support plate 392, and a hydraulic telescopic cylinder 394. The rotating support plate 392 is vertically arranged on the upper end of the positioning baffle 391, and the positioning baffle 391 and the rotating support plate 392 are L-shaped as a whole; a positioning suspension 41 is arranged on the outer wall of the press 4 at the front end of the sheet feeding component 3, and both ends of the connection between the positioning baffle 391 and the rotating support plate 392 are fixed to the positioning suspension 41 through a rotating shaft 393, and the hydraulic telescopic cylinder 394 is fixed to the positioning suspension 41, and the front end of the hydraulic telescopic rod 395 arranged in the hydraulic telescopic cylinder 394 is hinged on the rotating support plate 392 The end measuring component 38 includes a measuring telescopic cylinder 381, a forward support plate 382, ​​a measuring movable slide rail 383, and a sheet length measuring system software. The measuring movable slide rail 383 is installed on the sheet conveying frame 31 and its direction is perpendicular to the sheet conveying roller 32. The measuring telescopic cylinder 381 is installed on the measuring movable slide rail 383 and its sliding is controlled by a measuring displacement motor. The forward support plate 382 is fixed on the telescopic rod of the measuring telescopic cylinder 381, and the forward support plate 382 is perpendicular to the measuring movable slide rail 383. A pressure sensor 384 is arranged on one side of the front end of the forward support plate 382. After the front end of the high-temperature blank sheet 100 contacts the positioning baffle 391, the sheet conveying roller 32 stops rotating and conveying; the forward support plate 382 extends under the action of the measuring telescopic cylinder 381, and then the measuring telescopic cylinder 381 slides on the measuring moving slide rail 383 under the control of the measuring displacement motor. When the pressure sensor 384 contacts the end of the high-temperature blank sheet 100, the measuring displacement motor stops working; finally, the sheet length measurement system software is used to calculate the rotational displacement length of the measuring displacement motor, and then the total length between the initial position of the pressure sensor 384 and the positioning baffle 391 (which can be measured in advance and input into the system) is subtracted. After the overall calculation, the length of the high-temperature blank sheet 100 can be obtained.

[0031] Among them, an infrared thermometer 30 is installed on the positioning suspension 41 above the front end of the sheet conveyor frame 31 to detect the temperature of the high-temperature blank sheet 100 entering the press 4. If the temperature is too low, it will affect the stamping effect of the high-temperature blank sheet 100 in the press 4. If the temperature does not meet the standard, an alarm will be issued and manual exit will be performed.

[0032] The air cooling mechanism 6 is composed of a chain transmission line and a plurality of high-speed fans installed below the chain transmission line. The high-temperature stamping products passing through the chain transmission line are effectively cooled down by the air cooling effect of the high-speed fans.

[0033] Among them, the robot palletizing assembly 7 includes a robot manipulator 71, a positioning tray 72, a waste frame 73, a detection line 74, and a fence 75.

The stamped products transported to the end of the air cooling mechanism 6 are clamped in the positioning tray 72 by the robot manipulator 71 to complete storage; at the same time, the robot manipulator 71 will put the stamped products into the detection line 74 according to the specified sampling ratio to complete product quality inspection. After passing the inspection, the robot manipulator 71 automatically grabs and palletizes, and products with unqualified product quality will be clamped in the waste frame 73 for storage.

[0034] In the heating furnace 1, the heating of the medium and thick plate blank 100 of high-strength steel is realized. The medium and thick plate blank 100 of high-strength steel is heated to 850°C and taken out of the furnace. The temperature is detected by an infrared temperature detector set at the outlet of the heating furnace 1. If the detected temperature is unqualified, it will be returned to the furnace for further heating; if the temperature is qualified, the heated blank 100 is manually detected while passing through the roller conveyor line 2. If it is observed that the blank 100 is severely deformed, it will be transported on the roller conveyor line 2 without entering the next production step. Only the blank 100 that has passed the inspection will continue to be transported to the sheet feeding assembly 3. A stamping die is set in the press 4, and the stamping and shearing of the medium and thick plate products of high-strength steel are realized in the press 4. The 180° flipping of the medium and thick plate products of high-strength steel is realized by the flipping mechanism 5, and the flipping mechanism 5 has been disclosed in another patent of the company (publication number CN207748474U), and its specific structure will not be described in detail in this application. The air cooling mechanism 6 is used to cool the high-strength steel medium and thick plate products; the robot stacking component 7 is used to detect and sort the high-strength steel medium and thick plate products into boxes.
