[0023] As an optional embodiment, at least two symmetrically arranged protrusions 9 are provided on the top of the carrier plate 4 , and the protrusions 9 are used to make the hinge parallel to the carrier plate 4 .

[0024] For example, since the hinge joint is a hollow cylinder, the hinge is placed flat on the loading plate 4 in an inclined state, which is not conducive to the pushing assembly 7 driving the hinge to separate from the loading box 3. By setting the protrusion 9, the hinge is supported by the protrusion 9 and is parallel to the loading plate 4 when it is placed flat.

[0025] As an optional embodiment, two grooves 10 are provided on the top of the feeding connecting plate 6, one end of each of the grooves 10 is connected to one end of the feeding connecting plate 6 close to the lower mold, and the other end is connected to the top of the loading box 3, and according to the placement state of the hinge, the hinge of the hinge is placed in the corresponding groove 10 for limiting.

A torsion spring structure is provided; The driving member is fixed on the pushing plate 14 , and the driving member is drivingly connected to one side of the feeding connecting plate 6 .

[0029] As an optional embodiment, the driving member includes: A connecting block 17 is slidably connected to the feeding connecting plate 6, one end of the connecting block 17 is fixedly connected to the pushing plate 14, and the other end is vertically fixed with a first mounting plate 18; The first rack 19 is fixedly arranged beside the feeding connecting plate 6; The motor 20 is fixed on the top of the first mounting plate 18 . The output shaft of the motor 20 passes through the first mounting plate 18 and is fixed with a first gear 21 . The first gear 21 is meshed with the first rack 19 .

[0030] For example, the motor 20 drives the first gear 21 to rotate on the first rack 19, so that the first gear 21 drives the first mounting plate 18, the connecting block 17 and the push plate 14 to move, the push plate 14 drives the limit frame 15 to move, the limit frame 15 drives the limit rod 16 to move, the limit rod 16 drives the hinge to move to the steering assembly 8, firstly, the hinge is driven to disengage from the limit rod 16 through the steering assembly 8, and continues to move to the steering assembly 8 through the limit frame 15, and drives the steering assembly 8 to perform steering work during the continued movement of the limit frame 15 to complete the steering work of the hinge, and then, the steering assembly 8 is reset through the reset, so that the hinge falls into the limit frame 15, and is restricted by the limit frame 15, which effectively avoids the problem that the hinge cannot fall into the placement groove of the lower mold, and the hinge is driven to move to the top of the placement groove of the lower mold through the limit frame 15, so that the hinge falls into the placement groove, and the limit frame 15 is reset to complete the automatic feeding of the hinge. As an optional embodiment, a second mounting plate 22 is provided on the side of the feeding connecting plate 6 away from the driving member, and the bottom of the second mounting plate 22 extends vertically and is fixedly connected to the feeding connecting plate 6. A first guide rod 23 is passed through the second mounting plate 22, and one end of the first guide rod 23 is limited to one side of the second mounting plate 22 by a round block, and a plug 24 is fixed on the other side of the first guide rod 23, and the plug 24 is chamfered. A first spring 25 is sleeved on the first guide rod 23, and the two ends of the first spring 25 respectively abut against the plug 24 and the second mounting plate 22, and two slots 26 adapted to the plug 24 are provided on the outer wall of the limit frame 15, and each of the slots 26 is respectively arranged close to one end of the limit frame 15.

[0031] For example, in order to make the hinge move accurately to the working area of ​​the steering assembly 8, two slots 26 are set on the limit frame 15, and a plug 24 and a first spring 25 are set. The limit frame 15 is restricted twice to improve the hinge's ability to fall accurately into the interior of the limit frame 15 after turning.

[0032] As an optional embodiment, the steering assembly 8 includes: A single-axis cylinder 27 is installed at the bottom of the feeding connecting plate 6; A first electromagnet 28 is inserted through the feeding connecting plate 6, the top surface of the first electromagnet 28 is flush with the top surface of the feeding connecting plate 6, and a connecting tube 29 is fixedly provided at the bottom of the first electromagnet 28, and the connecting tube 29 is rotatably connected to the telescopic rod of the single-axis cylinder 27; A second gear 30 is sleeved on the connecting tube 29 , and the second gear 30 is fixedly connected to an end of the connecting tube 29 away from the first electromagnet 28 ; The second rack 31 is slidably connected and arranged at the bottom of the feeding connecting plate 6, and the second rack 31 drives the connecting tube 29 to move upward through the single-axis cylinder 27, so that the second gear 30 is meshed with the second rack 31; A steering connecting plate 32 is arranged beside the charging box 3, one side of the steering connecting plate 32 is fixedly connected to one end of the second rack 31, and the other side is slidably connected to a shift rod 33 in the up-down direction, and a rectangular through hole 34 is provided on the shift rod 33, and a first inclined surface 35 is provided at the bottom of the rectangular through hole 34; A push rod 36 is arranged on the top of the feeding connecting rod, and one end of the push rod 36 is bent downward and fixedly connected to the push assembly 7; A third mounting plate 37 is disposed below the shift lever 33, and one side of the third mounting plate 37 is bent upward and fixedly connected to the bottom of the steering connecting plate 32; A second guide rod 38 is passed through the third mounting plate 37, one end of the second guide rod 38 is fixedly connected to the bottom of the shift rod 33, and the other end is restricted to the bottom of the third mounting plate 37 by a round block; A second spring 39 is sleeved on the second guide rod 38, and two ends of the second spring 39 are respectively pressed against the shift rod 33 and the third mounting plate 37; An insert block 40, one end of which is provided with a second inclined surface 41 adapted to the first inclined surface 35, and the other end is fixedly connected to the bottom of the feeding connecting plate 6 by bending, and the insert block 40 is located at a place on the side of the first electromagnet 28 away from the charging box 3; A fixing block 42 is fixedly mounted on one side of the charging box 3; The third spring 43 has one end fixedly connected to the fixing block 42 , and the other end fixedly connected to the steering connecting plate 32 .

[0033] For example, a camera can be set at the top of the steering work area for remote control. When the hinge moves to the steering work area, the camera determines whether the current state of the hinge matches the lower mold placement slot. If it matches, the steering assembly 8 does not work, and the limit frame 15 directly drives the hinge to move toward the lower mold. If it does not match, the first electromagnet 28 is energized to suck the hinge, and the first electromagnet 28 is driven by the single-axis cylinder 27 to move upward, so that the hinge is separated from the feeding connecting plate 6. At this time, the limit frame 15 continues to move and is hinged to the limit frame 15 through the limit rod 16. When the limit rod 16 encounters the connecting tube 29, it rotates to avoid, so that the limit frame 15 is sleeved on the connecting tube 29. At the same time, when the limit rod 16 disengages from the connecting tube 29 and conflicts with it, it is reset under the influence of the torsion spring structure. During the continued movement of the limit frame 15, the limit frame 15 drives the push rod 36 to move, so that the push rod 36 conflicts with the gear rod 33, and drives the gear rod 33 to move After the first gear 21 is rotated, the connecting tube 29 is driven by the connecting tube 29 to rotate, and the connecting tube 29 drives the first electromagnet 28 to rotate to complete the steering work of the hinge. After the steering, the single-axis cylinder 27 drives the first electromagnet 28 to reset, so that the hinge falls into the interior of the limit frame 15, and the second gear 30 and the second rack 31 are no longer engaged. At this time, the first electromagnet 28 is powered off, the limit frame 15 continues to move, and the push rod 36 continues to drive the gear rod 33 to move to the plug block 40, so that the plug block 40 enters the rectangular through hole 34, and the first inclined surface 35 and the second inclined surface 41 cooperate to make the gear rod 33 move down to disengage from the contact of the push rod 36. Afterwards, the steering connecting plate 32 is reset by the action of the second spring 39, thereby completing the steering work of the hinge and the reset work of the steering assembly 8.

[0034] As an optional embodiment, the blanking component 2 includes: A support plate 44 is fixedly mounted on a side of the punching machine 1 away from the charging box 3; A conveyor 45 is fixedly mounted on the top of the support plate 44, and one end of the conveyor 45 is disposed close to the lower mold; A support frame 46 is fixed on the top of the conveyor 45; The double-axis cylinder 47 is fixedly mounted on the top of the support frame 46 , and a second electromagnet 48 is fixedly mounted on the telescopic rod of the double-axis cylinder 47 .

[0035] For example, after the hinge punching is completed, the second electromagnet 48 is driven by the double-axis cylinder 47 to move to the top of the lower mold placement slot, and the second electromagnet 48 is energized to suck out the hinge. Then the double-axis cylinder 47 is reset to move the hinge to the top of the conveyor 45, and the second electromagnet 48 is deenergized to make the hinge fall onto the conveyor 45 and be transferred to the next process, thereby completing the material removal work after the hinge punching is completed.
