At the same time, adjust the external loading and transportation equipment to the top of the feeding gantry 3, move the external discharging and transportation equipment and cleaning equipment to the bottom of the discharging gantry 5, and then replace the suitable inner mold and inner stamping mold according to the model of the precision mechanical parts required for stamping processing. The inner mold is used to be installed on the bracket 104, and a number of through holes are opened on the surface of the inner mold, such as Figure 6 As shown, but not limited to this, the group of inner dies and inner stamping dies are used to adapt the middle plate 604 and the side plate 603.

[0029] The top of the supporting die base 1 is symmetrically recessed with a pressing groove 101 on both sides, an adjusting baffle 102 is arranged on the outer wall of the pressing groove 101, a micro-motion cylinder is arranged between the pressing groove 101 and the adjusting baffle 102, a bracket 104 is arranged on the middle inner wall of the leakage groove 103, and multiple sets of outer frames 201 are symmetrically arranged on the outer walls of both sides of the upper die base 2. The inner stamping module 202 is sleeved on the bottom center of the upper die base 2, and the guide rail 401 drives the movable template 6 to transport the material into the supporting die base 1 for stamping processing. When the inner stamping die is in contact with the raw material surface, the raw material is stamped, and some debris produced by the stamping process falls along the gap between the side plate 603 and the middle plate 604, and enters the slag discharge port along the leakage groove 103.

[0030] A connecting frame 301 connected to the end face of the supporting mold base 1 is arranged at the bottom of the feeding gantry 3, and a plurality of lifting columns 302 are arranged on the top of one end of the connecting frame 301 away from the supporting mold base 1, and a rotating motor 304 is located between the plurality of lifting columns 302. Side beams 303 slidably sleeved with the lifting columns 302 are arranged on the outer walls on both sides of the rotating motor 304. When the external feeding and transportation equipment puts the raw materials onto the movable template 6 in the guide rail 401, a lifting cylinder connected to the side beam 303 is arranged in the lifting column 302, and the lifting cylinder drives the side beam 303 to gradually slide down along the axial direction of the lifting column 302, and it gradually descends according to the travel distance of the movable template 6 along the rotating conveyor frame 4 to the supporting base, and After the movable template 6 drives the raw material and the inner mold on the bracket 104 to form an upper and lower alignment calibration, the lifting cylinder drives the rotating conveyor frame 4 to slide down again until the movable template 6 drives the raw material to embed into the supporting base. After the processing is completed, the lifting cylinder drives the rotating conveyor frame 4 to slide vertically until the rotating conveyor frame 4 is located at the midpoint between the supporting base and the upper die seat 2, and the guide rail 1 401 drives the movable template 6 used therewith to move to the top of the unloading gantry 5, and the guide rail 2 402 drives the movable template 6 used therewith to move to the bottom of the loading gantry, and the rotating motor 304 drives the rotating conveyor frame 4 to rotate at a uniform speed through the coupling and related accessories, so that the directions of the guide rails 1 401 and 2 402 are reversed.

[0031] A sleeve is symmetrically provided through the middle of both ends of the rotating conveyor frame 4, and the sleeve is connected to the rotating motor 304 through relevant accessories, such as a coupling and a shaft rod, in a sleeve or clamping manner. A guide rail 401 is recessed on the top of the inner wall of both sides of the rotating conveyor frame 4, and a guide rail 402 is recessed below the guide rail 401. A propulsion cylinder is provided inside the guide rail 401 and the guide rail 402, which is only used to drive the active template 6 to make a straight line reciprocating motion along the inside of the guide rail. The external loading and transportation equipment transports the stamping material to the top of the feeding gantry 3, and the mechanical arm 1 carried by the external loading and transportation equipment clamps the raw material and puts it to the top center of the nearby active template 6. The group of active templates 6 slides in the guide rail 401 to constitute preliminary loading, waiting for the active template 6 to transport the first group of raw materials to the support mold base 1 for After the processing is completed, semi-finished precision mechanical parts are obtained, and then the semi-finished precision mechanical parts are lifted to the area between the supporting die base 1 and the upper die base 2, and the rotating conveyor frame 4 drives the first group of semi-finished precision mechanical parts to move to the top of the discharge gantry 5 through the movable middle template 6, and the rotating conveyor frame 4 is driven by the rotating motor 304 to rotate, and the movable template 6 sliding in the guide rail 2 402 is driven by the propulsion cylinder inside the guide rail 2 402 during the movement of the rotating conveyor frame 4 on the stage, and moves along the guide rail 2 402 close to the feeding gantry 3, and with the rotation of the rotating conveyor frame 4, it stays under the external loading and transportation equipment to realize alternating loading, which greatly improves the overall high-efficiency and continuous loading and unloading processing process of the raw materials of precision mechanical parts, reduces the mechanical stagnation interval in the overall stamping loading and unloading alternation, and thereby improves the overall production efficiency.

[0032] An inner frame 601 is arranged inside the movable template 6, and side plates 603 are arranged on the inner walls at the bottom of both ends of the inner frame 601, and a middle plate 604 is arranged in the middle of both sides of the inner frame 601. A plurality of groups of grooves are symmetrically arranged on the surface of the frame on both sides of the inner frame 601, and a movable clamp 602 is sleeved inside the grooves. A fine-tuning cylinder 605 sleeved with the movable clamp 602 is arranged on the inner wall of the groove. When the guide rail 401 drives the semi-finished precision mechanical parts to approach the unloading gantry 5 and rotate, and the surface of the semi-finished precision mechanical parts is cleaned of residual debris by the external cleaning equipment, the external unloading transportation equipment approaches the bottom of the semi-finished precision mechanical parts through the robot arm 2 and attaches to it, the fine-tuning cylinder 605 mobilizes the movable clamp 602 to release the clamping of the semi-finished precision mechanical parts, so that the semi-finished precision mechanical parts are clamped by the robot arm 2 and placed on the external conveying equipment, and transported to the next processing area, and the cleaning equipment is reset to the bottom of the group of movable templates 6 again to clean the inside of the movable template 6.

[0033] Embodiment 2: This embodiment is a high-efficiency blanking stamping die suitable for precision machining, including an ultrasonic scanning sensor embedded in the bottom edge of the upper die seat 2, the unloading gantry 5 has the same structure as the feeding gantry 3, and an industrial camera facing the rotating conveyor frame 4 is arranged on the top frame of the unloading gantry 5, and the industrial camera is used to collect the surface reference value BM of the semi-finished precision mechanical parts, and the ultrasonic sensor is used to collect the body defect manifestation value QS of the semi-finished precision mechanical parts, and the acquired surface reference value BM and defect manifestation value QS are sent to the database of the external general equipment control room, forming a joint inspection and supervision system for stamping and production.

[0034] The stamping production joint inspection and supervision system uses the control panel on the stamping equipment body to control the equipment operation. After the upper die seat 2 completes the processing of a single group of raw materials, the ultrasonic sensor performs body scanning data collection on the group of semi-finished precision mechanical parts that have been stamped, and the body defect performance value QS of the semi-finished precision mechanical parts is collected accordingly. When the rotating conveyor frame 4 transports the semi-finished precision mechanical parts to the discharge gantry 5 area, multiple groups of industrial cameras are respectively installed on the top and bottom of the discharge gantry 5, which are used for multi-axial data collection of the surface of the semi-finished precision mechanical parts during the discharge transportation process, and the surface reference value BM of the semi-finished precision mechanical parts is collected accordingly, and the acquired surface reference value BM and defect performance value QS are sent to the database of the external general equipment control room.

[0035] Database through formula The production control coefficient R is obtained, where a and b are the proportional coefficients of the surface reference value BM and the defect performance value QS, respectively, a>b>0, and the preset production control coefficient YR stored in the database is retrieved for comparison and analysis with the production control coefficient R:

[0036] If the production control coefficient R>the preset production control coefficient YR, it is determined that there is an abnormality in the stamping processing of this group of semi-finished precision mechanical parts, and an alarm signal is generated. The alarm signal is sent to the display screen in the main control room and the control panel on the stamping equipment body, and the "Stamping group 002 / Production sequence 00034 abnormality / Plan 1 started / Dispatch for maintenance" is displayed in text style at the same time to remind the personnel in the main control room to dispatch maintenance engineers to go for maintenance, and to remind the personnel who control this group of equipment to suspend processing.

[0037] If the production control coefficient R is less than the preset production control coefficient YR, no signal is generated.

[0038] When an alarm signal is generated, the database marks the surface reference value BM and defect performance value QS that generate the alarm signal, and retrieves the preset surface range value threshold and defect range value threshold from the database for comparison and analysis with the surface reference value BM and defect performance value QS:

[0039] If the surface reference value BM is not within the preset surface range value threshold, and the defect manifestation value QS is not within the defect range value threshold, a first-level signal is generated, and the first-level signal is sent together with the alarm signal to the display screen in the main control room and the control panel on the stamping equipment body, and the display entry is updated, and the entry content is such as "Punching production group 002 / Semi-finished precision mechanical parts are severely damaged / Check raw materials / Check molds / Check and remove impurities".

[0040] If the surface reference value BM is not within the preset surface range value threshold, and the defect manifestation value QS is within the defect range value threshold, a secondary signal is generated, and the secondary signal is sent together with the alarm signal to the display screen in the main control room and the control panel on the stamping equipment body, and the display entry is updated, and the entry content is such as "Punching group 002 / Surface abnormality of semi-finished precision mechanical parts / Check mold / Check and remove impurities".

[0041] If the surface reference value BM is within the preset surface range value threshold, and the defect manifestation value QS is not within the defect range value threshold, a third-level signal is generated and sent together with the alarm signal to the display screen in the main control room and the control panel on the stamping equipment body, and the display entry is updated, and the entry content is such as "Stamping production group 002 / Stamping abnormality of semi-finished precision mechanical parts / Check mold".

[0042] If the surface reference value BM is within the preset surface range value threshold, and the defect manifestation value QS is within the defect range value threshold, a four-level signal is generated, and the four-level signal is sent together with the alarm signal to the display screen in the main control room and the control panel on the stamping equipment body, and the display entry is updated, and the entry content is such as "Punching group 002 / Check raw materials / Reset for inspection".

[0043] In combination with Example 1 and Example 2, the initial loading can be achieved by sliding the movable template 6 on the guide rail, the rotating conveyor frame 4 drives the movable template 6 to rotate to achieve alternating loading, and the lifting cylinder is used to accurately control the position of the movable template 6 to achieve alignment and calibration between the raw material and the mold, thereby improving the efficiency and continuity of loading and unloading, reducing mechanical stagnation, and improving the overall production efficiency. The defect performance value and surface reference value of the semi-finished product are collected by ultrasonic sensors and industrial cameras through the production and inspection joint supervision system, and the processing is judged to be abnormal through calculation and comparison. In case of abnormality, alarms and signals of different levels are generated, which is convenient for the deployment of maintenance personnel and ensures production quality and equipment maintenance.
