A rectangular through hole is opened on the top of the hanger body 221. Two symmetrically distributed rectangular slide grooves are opened on the front of the hanger body 221. The inner walls on both sides of the hanger body 221 are fixedly connected with a transverse sleeve 222. The transverse sleeve 222 is slidably connected with a transverse sleeve rod 223 for assisting in stabilizing the hydraulic punch assembly 23. The outer end of the transverse sleeve rod 223 is rotated. The inner walls on both sides of the hanger body 221 are fixedly connected with Hall sensors 224 for detecting the distance change data from the Hall sensor 224 to the metal wheel of the lateral displacement sleeve rod 223. The Hall sensors 224 are all located inside the hanger body 221. The Hall sensors 224 are electrically connected to the electric control box 6 through a wire. The hanger body 221 and the lateral displacement sleeve rod 223 are fixedly connected through a spring. The number of the lateral displacement sleeve 222, the lateral displacement sleeve rod 223 and the Hall sensors 224 are all four, two in a group, and the two groups are symmetrically distributed about the front of the hanger body 221. The hydraulic punch assembly 23 is connected to the top of the punch hanger 22, and is used to install the upper half of the reinforcing plate mold and perform the stamping process. The hydraulic punch assembly 23 includes a punch main cylinder 231, which is connected to the top of the hanger body 221. The back of the punch main cylinder 231 is connected to the external oil pump and the hydraulic oil tank through a rubber tube. The punch main cylinder 231 is slidably connected to the punch body 232, and the bottom of the punch body 232 is fixedly connected to the front and rear mounting plate frames 233. The number of the front and rear mounting plate frames 233 is two and is fixedly connected to the front and back of the punch main cylinder 231.

The inner side of the outer wall of the side support plate frames 234 is fixedly connected to a rubber plate for stabilizing the mold from the left and right sides and cooperating with the transverse sleeve rod 223 to stabilize the punch body 232. The plate frame with the rubber plate improves the stability of the stamping mold, absorbs the impact force of the punch, and prevents the impact force from interfering with the mold and the metal plate. The processing accuracy and processing quality of stamping are improved; A clamping and moving mechanism 3 is fixedly connected to the top of the bed base 1, a thickness detection mechanism 4 is fixedly connected to the top of the bed base 1, a thickness correction mechanism 5 is fixedly connected to the top of the bed base 1, the thickness detection mechanism 4 is located on the back of the stamping forming mechanism 2, the thickness correction mechanism 5 is located on the back of the thickness detection mechanism 4, and an electric control box 6 is fixedly connected to the right side of the bed base 1.

[0023] When in use, before starting the device, fix the lower half of the stamping die of the inner reinforcement plate of the B-pillar inside the die base 21, and fix the upper half of the stamping die of the inner reinforcement plate of the B-pillar to the front and rear mounting plate frames 233 by bolts. After the fixing is completed, start the electric control box 6, and start the stamping forming mechanism 2 and the clamping and moving mechanism 3 through the electric control box 6. After the metal plate to be formed is fixed by the clamping and moving mechanism 3, the clamping and moving mechanism 3 brings the metal plate to the top of the die inside the die base 21. Subsequently, the oil pump connected to the punch main cylinder 231 discharges the hydraulic oil into the punch main cylinder 231, and the punch main body 232 moves downward under the action of the hydraulic oil. The punch main body 232 also drives the upper half of the die to move downward until the upper and lower parts of the die clamp the metal plate and are completely closed. The forming process is completed, and the punch main body 232 drives the upper half of the die to reset. After the punch main body 232 is reset, the clamping and moving mechanism 3 drives the formed reinforcement plate to pass through the thickness detection mechanism 4 and the thickness correction mechanism 5 to perform thickness detection and correction processes. During this process, when the punch body 232 moves slightly in the horizontal direction, it will be squeezed with the rubber plates of the front and rear mounting plates 233 and the side support plates 234. The rubber plates will elastically deform to reduce the lateral movement of the punch body 232. The front and rear mounting plates 233 and the metal wheels of the transverse sleeve 223 will slide relative to each other. The metal wheels will drive the transverse sleeve 223 to slide along the transverse sleeve 222. The transverse sleeve 223 will squeeze the spring, and at the same time the spring will absorb part of the vibration to reduce the vibration transmitted to other positions of the equipment. The Hall sensor 224 detects the distance data from itself to the transverse sleeve 223, and transmits the data back to the electronic control box 6. The electronic control box 6 adjusts the oil pump speed according to the transmitted data, thereby preventing the small horizontal movement from being too large and affecting the forming accuracy.

The bottom of the multi-way solenoid valve 52 is connected to a hydraulic push rod 53. The hydraulic push rod 53 is located inside the support frame 51. There are six hydraulic push rods 53 and they are evenly arranged at the bottom of the multi-way solenoid valve 52. The bottom of the hydraulic push rod 53 is rotatably connected to a correction rubber roller 54 for correcting the thickness of the metal plate by extrusion. The number of the support frame 51 and the multi-way solenoid valve 52 are both two and they are symmetrically distributed at the top and bottom of the bed base 1.

[0027] When in use, the reinforcing plate first passes through the soft brush at the bottom of the cleaning brush bracket 412 under the drive of the clamping moving mechanism 3 to clean the granular impurities on its surface to prevent the impurities from affecting the measurement results. When the metal plate passes through the distance sensor of the sensor bracket 413, the sensor bracket 413 feeds back the signal to the electric control box 6, and the electric control box 6 controls the laser rangefinder 43 to start. After the laser rangefinder 43 is started, the detected thickness data of the reinforcing plate is fed back to the electric control box 6 in real time. The electric control box 6 adjusts the speed of the oil pump connected to the multi-way solenoid valve 52 and the position of the solenoid valve of the multi-way solenoid valve 52 according to the data fed back by the laser rangefinder 43 and the push rod stroke fed back by the rear electric push rod 33, thereby realizing the control of the stroke of the hydraulic push rod 53. When the reinforcing plate reaches the bottom of the hydraulic push rod 53, the hydraulic push rod 53 adjusts the stroke under the control of the electric control box 6, and drives the correction rubber roller 54 to squeeze and correct the excessively thick position of the reinforcing plate. When the reinforcing plate completely leaves the thickness correction mechanism 5 and disengages from the rear electromagnetic chuck 34, the reinforcing plate is taken out to complete the current forming process.
