The No. 1 conveying component 31 and The purpose of the second handling assembly 32 is only to realize the lateral and longitudinal movement of the connecting arm 35, and the purpose of the mechanical clamp 36 is to clamp the metal frame workpiece for easy handling. The movement principle is not described in detail. The fixed platform 1 is provided with a shock absorber 8, and the lifting platform 2 is provided with a second fixing rod 9 used in conjunction with the shock absorber 8, which is convenient for providing buffering during the rapid stamping process of the lifting platform 2 descending. The lifting platform 2 is also provided with guide rods 11 of different sizes, and the fixed platform 1 is provided with a corresponding wire groove 10 used in conjunction with it. The trimming mold 5 is provided with a second limit block 12, which is used to limit the metal frame workpiece before it falls from the metal sheet after being stamped, and prevent the metal sheet from going off. ;

[0024] In this embodiment, a transfer table 4 is arranged on the fixed table 1 between the trimming die 5 and the lower die 7 for placing the metal frame workpiece taken from the lower die 7 and turned over, and a first hole slot 41 and a second hole slot 42 are arranged on the transfer table 4, facilitating that during the process of the connecting arm 35 descending to place the metal frame workpiece, the connecting block 331 and the mechanical claw 36 on the connecting arm 35 will not be blocked by the tabletop of the transfer table 4.

[0025] Specifically, during the process of the stamping die 6 pressing downward and preparing for the next stamping, through the cooperation of the first handling component 31 and the second handling component 32, the connecting arm 35 arranged between the lower die 7 and the trimming die 5 moves downward to the last stamping working area on the lower die 7, and the formed metal frame workpiece is grabbed by the mechanical claw 36 thereon and placed on the transfer table 4, thereby realizing continuous stamping and handling the stamped metal frame workpiece. After the original metal frame workpiece is stamped, taking out the stamped metal frame workpiece manually to another working area not only has low continuity, resulting in slow production, but also is not conducive to the safety of the staff, requiring the staff to always be vigilant, which cannot meet the production requirements of the factory for the metal frame workpiece.

[0026] Embodiment 2: On the basis of embodiment 1, the connecting arm 35 is provided with a straightening assembly 33, which is used to push the dislocated metal frame workpiece to the designated pick-up and placement location when the mechanical clamp 36 clamps the metal frame workpiece; the straightening assembly 33 includes a connecting frame 333 that can move up and down in the longitudinal direction, and the connecting arm 35 is provided with a connecting block 331, and the connecting block 331 is provided with a No. 1 electric push rod 332, and the output end of the No. 1 electric push rod 332 is fixedly connected to the top surface of the connecting frame 333, and is used to drive the connecting frame 333 to move up and down in the longitudinal direction. A push-pull mechanism 336 is provided on the inner side of the connecting frame 333, which is used to drive the rubber block 339 to move from the inner side of the metal frame workpiece to the inner wall of the metal frame workpiece, and then push the metal frame pendant package to the designated clamping position; the push-pull mechanism 336 includes two symmetrically arranged movable seats 3362, and a gear is provided between the two movable seats 3362. The rack and pinion transmission member 3364 enables the two movable seats 3362 to move in opposite directions and send the misplaced metal frame workpiece to the designated pick-up and placement position through the rubber block 339 thereon. The rack and pinion transmission member 3364 is specifically two racks and a transmission gear arranged in the middle. The two racks are respectively connected to the corresponding movable seats 3362, and a transmission gear is arranged between the two racks. The transmission gear is rotatably connected to the connecting frame 333 to enable the two racks to move in opposite directions. A No. 5 slider 3363 is respectively arranged on the two movable seats 3362, and a No. 1 slide groove 334 for sliding is opened on the connecting frame 333, and a No. 2 electric push rod 3361 is arranged inside the connecting frame 333. The output end of the No. 2 electric push rod 3361 is fixedly connected to one of the movable seats 3362. The No. 2 electric push rod 3361 is an existing technology and is only used. Its movement principle is not described in detail.

[0027] Specifically, during the process of the connecting arm 35 moving downward in the longitudinal direction, the connecting arm 35 first pauses in the air, and then during this time gap, the No. 1 electric push rod 332 pushes the connecting frame 333 to move downward, so that its height is lower than the height of the mechanical clamp 36, and the connecting frame 333 is lowered to the same height as the stamped metal frame workpiece, and then the No. 2 electric push rod 3361 pushes one of the movable seats 3362 to slide inside the connecting frame 333, and then the gear rack transmission member 3364 drives the other movable seat 3362 to move with the other movable seat 3362. A movable seat 3362 moves in the opposite direction, which can solve the problem that when the metal frame workpiece hits the stamped metal frame workpiece during the rising process of the stamping die 6, or the metal frame workpiece is misplaced due to the vibration generated during the rising process, the misplaced metal frame workpiece can be straightened through the rubber block 339 to prevent the mechanical clamp 36 from directly hitting the top wall of the metal frame workpiece during the downward movement, causing the metal frame workpiece to be squeezed and damaged. What is more serious is that the mechanical clamp 36 may be damaged, which not only causes economic losses, but also makes the entire system disordered and has to be shut down for repair.

[0028] Embodiment 3: On the basis of Embodiment 2, a set of unfolding mechanisms 337 is provided on each of the movable seats 3362; a set of the unfolding mechanisms 337 includes two rotating shafts 3371 rotatably connected to the movable seats 3362, and the rotating shafts 3371 are arranged through the bottom wall of the connecting frame 333, and each of the rotating shafts 3371 is respectively provided with a No. 1 gear 3372, and the two No. 1 gears 3372 are meshingly connected.

[0029] In this embodiment, each group of the unfolding mechanism 337 also includes a No. 1 rack 3375 fixedly connected to the bottom surface of the connecting frame 333, and a No. 2 gear 3373 capable of meshing with the No. 1 rack 3375 is provided at the lower end of one of the rotating shafts 3371, so that the two sleeves 3381 in a group can be rotated and unfolded before the rubber block 339 is attached to the inner wall of the metal frame, so that four-point positioning of the inner wall of the metal frame can be achieved, making the positioning more accurate, and after the positioning is completed, the two adjacent sleeves 3381 can be rotated in a parallel state and retracted into the inner side of the connecting frame 333, thereby reducing space occupancy and avoiding unnecessary movement interference.

[0030] In this embodiment, a No. 6 slider 3376 is provided on the sleeve 3381, and a No. 2 slide groove 335 is provided on the connecting frame 333 for the No. 6 slider 3376 to slide. The purpose of setting the No. 6 slider 3376 is to limit the sleeve 3381 in the interval when the No. 1 rack 3375 is disengaged from the No. 2 gear 3373, so as to prevent it from rotating arbitrarily and reduce unnecessary wear. The side of the No. 6 slider 3376 close to the connecting frame 333 is composed of two inclined surfaces symmetrically arranged along the center line of the No. 6 slider 3376. When the No. 6 slider 3376 returns to the inside of the No. 2 slide groove 335 again, it will not get stuck.

[0031] Specifically, during the movement of the movable seat 3362, the rotating shaft 3371 thereon is driven to move. During this process, the No. 6 slider 3376 slides inside the No. 2 slide groove 335. As the No. 6 slider 3376 moves out of the No. 2 slide groove 335, it just meshes with the No. 1 rack 3375, thereby pushing the No. 2 gear 3373 to rotate. The No. 2 gear 3373 drives the No. 1 gear 3372 connected to it to rotate through the rotating shaft 3371, thereby causing the other No. 1 gear 3372 to rotate in the opposite direction, thereby realizing the rotation and expansion of the two adjacent rubber blocks 339, and performing four-point positioning on the inner wall of the metal frame workpiece, which can enable the metal frame workpiece to be accurately moved to the specified position that can be clamped by the mechanical clamp 36, and when the metal frame workpiece is reset, the rubber block 339 can return to the initial position, and the rotating shaft 3371 is retracted into the inner side of the connecting frame 333, reducing space occupancy and avoiding unnecessary motion interference.

[0032] Embodiment 4: On the basis of embodiment 3, each of the No. 1 gear 3372 is provided with a length adjustment mechanism 338, so as to adjust the initial position of the rubber block 339 according to the shape of the metal frame workpiece; the length adjustment mechanism 338 includes a sleeve 3381 fixedly connected to the No. 1 gear 3372, a movable slide bar 3383 is provided inside the sleeve 3381, and a rubber block 339 is fixedly connected to the end of the slide bar 3383 away from the sleeve 3381 for pushing the metal frame workpiece, and a No. 3 electric push rod 3382 is provided inside the sleeve 3381, and the output end of the No. 3 electric push rod 3382 is fixedly connected to the slide bar 3383. The No. 3 electric push rod 3382 is a prior art and is only used without further description.

[0033] Specifically, the relative length between the No. 3 electric push rod 3382 and the sliding rod 3383 can be adjusted through the No. 3 electric push rod 3382, that is, the initial position of the rubber block 339 can be adjusted, so that the initial position of the rubber block 339 can be adjusted according to the shape of the metal frame workpieces of the same batch, and the metal frame workpieces of different shapes and sizes that are misplaced can be straightened to the original position.

[0034] Embodiment 5: On the basis of embodiment 4, the continuous transport unit 3 also includes an automatic flipping component 34; before the metal frame workpiece on the lower mold 7 is transported to the transfer table 4, it is automatically flipped; the automatic flipping component 34 includes a base plate 346, and a plurality of equidistantly arranged circular shafts 347 are arranged on the base plate 346, and a rotating shaft 349 is arranged on the connecting arm 35, specifically, the rotating shaft 349 is rotatably connected to the No. 2 slide 315, and the connecting arm 35 is fixedly connected to the rotating shaft 349, and an incomplete gear 3410 is arranged on the rotating shaft 349, and a No. 1 limit block 3411 is arranged on the incomplete gear 3410. It should be noted that the number and size of the teeth on the incomplete gear 3410 and the number and size of the circular shafts 347 can satisfy the connection arm 35 to rotate one hundred and eighty degrees, thereby realizing automatic flipping.

[0035] In this embodiment, the automatic flipping component 34 also includes a No. 3 connecting seat 341 arranged on the fixed platform 1, and a plurality of No. 1 fixing rods 342 are arranged on the No. 3 connecting seat 341. A lifting plate 344 is slidably arranged on the plurality of No. 1 fixing rods 342. A spring 343 arranged between the No. 3 connecting seat 341 and the lifting plate 344 is sleeved on the outer side of each of the No. 1 fixing rods 342, and the lifting plate 344 is connected to the bottom plate 346 through a connecting rod 345, which is used for the connecting arm 35 to move downward longitudinally, so that the bottom plate 346 and the circular shaft 347 and the limit seat 348 thereon can be lowered together without getting stuck.

[0036] In this embodiment, two No. 1 limit blocks 3411 are provided, and the two No. 1 limit blocks 3411 are symmetrically arranged on both sides of the teeth on the incomplete gear 3410 .

[0037] Specifically, when the No. 1 transport component 31 drives the connecting arm 35 to move horizontally to transport the metal frame workpiece on the lower mold 7 to the transfer platform 4, the rotating shaft 349 can drive the incomplete gear 3410 on it to move, and the No. 1 limit block 3411 on the incomplete gear 3410 can slide on the first section limit seat 348, limiting the free rotation of the connecting arm 35 driven by the rotating shaft 349 to ensure the stability of the system. When the No. 1 limit block 3411 just detaches from the first section limit seat 348, the circular shaft 347 is stuck in the tooth groove formed by the two teeth of the incomplete gear 3410, forcing the incomplete gear 3410 to rotate one hundred and eighty degrees, and the other No. 1 limit block 3411 rotates and fits onto the second section limit seat 348 for limiting. At this point, when the stamped metal frame workpiece in the continuous transport film is realized, the rotation of the connecting arm 35 can be realized, which also drives the metal frame workpiece to automatically turn over, thereby realizing the integration of continuous automatic film transport and turning over, reducing the burden on the staff and increasing efficiency.

[0038] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
