Description

Technical Field

[0001] The invention relates to the technical field of hinge processing, and in particular to a punching device for hinge production. Background Art

[0002] Hinge, as one of the door and window hardware, is a component that connects two parts of an object and enables them to move. It has a very wide range of uses and a large production demand.

[0003] In the traditional manufacturing industry, hinges are mostly processed by hand because of low labor costs. However, with the development of society, the increase in labor costs and the gradual popularization of mechanization, there is an urgent need for a device that can completely replace manual labor to fully realize the punching processing of hinges.

[0004] During manual processing, the other half of the hinge is grasped by hand and directly sent into the stamping equipment. During stamping, the fingers are only one or two centimeters away from the stamping head, which is very dangerous. In order to improve efficiency, workers must always follow the stamping frequency of the equipment to pick up the workpiece, which increases the mental and physical fatigue of workers and the error rate of operation. For this reason, we propose a device that can completely replace manual operation and realize automatic punching to solve the existing problems. Summary of the invention

[0060] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0062] As Figures 1 to 10 shown, a stamping device for hinge production includes a stamping machine 1. An upper die and a lower die are installed on the stamping machine 1. A feeding component is installed on one side of the stamping machine 1, and a blanking component 2 is installed at the other end. The feeding component includes:

[0063] A loading box 3, fixedly arranged on one side of the stamping machine 1. A loading plate 4 is slidably connected inside the loading box 3;

[0064] A lifting assembly 5 is installed on one side of the charging box 3, and the lifting assembly 5 is drivingly connected to the loading plate 4;

[0065] A feeding connecting plate 6 is mounted on the punching machine 1, one end of the feeding connecting plate 6 is attached to the lower die, and the other end is sleeved on the top of the charging box 3, the feeding connecting plate 6 is fixedly connected to the charging box 3, and the top of the feeding connecting plate 6 is flush with the top of the lower die;

[0066] A material pushing assembly 7 is arranged on the top of the material feeding connecting plate 6, and the material pushing assembly 7 is slidably connected to the material feeding connecting plate 6;

[0067] A steering assembly 8 is mounted on the feeding connecting plate 6, the steering assembly 8 is located between the charging box 3 and the lower mold, and the steering assembly 8 is transmission-connected to the pushing assembly 7;

[0068] The pusher assembly 7 drives the hinge to move to the steering assembly 8, and the pusher assembly 7 drives the steering assembly 8 to steer the hinge, so that the direction of the hinge processing matches the lower mold.

[0069] For example, the lifting assembly 5 drives the carrier plate 4 to move upward, so that the hinge on the carrier plate 4 moves to the top of the feeding connecting plate 6, and the pushing assembly 7 drives the hinge to move to the steering assembly 8. If the hinge is placed in a state that does not match the placement slot on the lower mold, the pushing assembly 7 and the steering assembly 8 cooperate to complete the steering work of the hinge. When the hinge matches the placement slot on the lower mold, the pushing assembly 7 continues to work to drive the hinge to move into the placement slot of the lower mold, and then the pushing assembly 7 is reset, and the punching machine 1 works to complete the punching work of the hinge. After the punching machine 1 is reset, the punched hinge is taken out by the unloading assembly 2, thereby completing the punching work of a hinge, realizing the automated loading work of the hinge punching process, improving work efficiency, and reducing labor costs.

[0070] 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 .

[0071] 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.

[0072] 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.

[0073] As an optional embodiment, the lifting assembly 5 includes:

[0074] The screw slide 11 is fixedly mounted on one side of the charging box 3;

[0075] At least one slide groove 12 is opened on one side of the charging box 3, and a lifting connecting plate 13 is slidably connected in the slide groove 12. One end of the lifting connecting plate 13 is fixedly connected to one side of the loading plate 4, and the other end is fixedly connected to the slider of the screw slide 11.

[0076] For example, the screw slide 11 drives the lifting connecting plate 13 to move in the slide groove 12, and the lifting connecting plate 13 drives the loading plate 4 to move, thereby completing the loading work of the hinge.

[0077] As an optional embodiment, the pusher assembly 7 includes:

[0078] A push plate 14, slidably connected to the feeding connecting plate 6;

[0079] A limit frame 15, one end of which is fixedly connected to one end of the push plate 14 close to the lower mold, and the other end is open, and the limit frame 15 is transmission-connected to the steering assembly 8;

[0080] Two limit rods 16 are arranged inside the limit frame 15, and one end of each limit rod 16 is hinged to an inner wall of the limit frame 15, and the hinge of one end of the limit rod 16 is close to the push plate 14 on one side with a rounded corner, and the other side is a right angle portion, and the right angle portion abuts against the inner wall of the limit frame 15, and each limit rod 16 is hinged to the inner wall of the limit frame 15. A torsion spring structure is provided;

[0081] 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 .

[0082] As an optional embodiment, the driving member includes:

[0083] 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;

[0084] The first rack 19 is fixedly arranged beside the feeding connecting plate 6;

[0085] The motor 20 is fixedly installed 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 fixedly provided with a first gear 21, and the first gear 21 meshes with the first rack 19.

[0086] 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 pushing plate 14 to move. The pushing plate 14 drives the limiting frame 15 to move, the limiting frame 15 drives the limiting rod 16 to move, and the limiting rod 16 drives the hinge to move to the steering assembly 8. First, the steering assembly 8 drives the hinge to disengage from the limiting rod 16, and the limiting frame 15 continues to move to be sleeved on the steering assembly 8. During the continuous movement of the limiting frame 15, the steering assembly 8 is driven to perform a steering operation to complete the steering operation of the hinge. After that, through the reset of the steering assembly 8, the hinge falls into the limiting frame 15. Restricted by the limiting frame 15, the problem that the hinge cannot fall into the placement groove of the lower mold is effectively avoided. The limiting frame 15 drives the hinge to move to the top of the placement groove of the lower mold, so that the hinge falls into the placement groove, and the limiting frame 15 is reset to complete the automatic feeding work of the hinge.

[0087] As an alternative embodiment, a second mounting plate 22 is provided on the side of the feeding connecting plate 6 away from the driving member. 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. One end of the first guide rod 23 is restricted on one side of the second mounting plate 22 by a round block. A plug 24 is fixedly provided on the other side of the first guide rod 23. The plug 24 is chamfered. A first spring 25 is sleeved on the first guide rod 23. The two ends of the first spring 25 respectively abut against the plug 24 and the second mounting plate 22. Two slots 26 adapted to the plug 24 are provided on the outer wall of the limiting frame 15, and each slot 26 is respectively arranged near one end of the limiting frame 15.

[0088] For example, in order to accurately move the hinge to the working area of the steering assembly 8, by providing two slots 26 on the limiting frame 15, by providing the plug 24 and the first spring 25, and by restricting the limiting frame 15 twice, the hinge can accurately fall into the inside of the limiting frame 15 after turning.

[0089] As an alternative embodiment, the steering assembly 8 includes:

[0090] A single-axis cylinder 27 is installed at the bottom of the feeding connecting plate 6;

[0091] The 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. A connecting cylinder 29 is fixedly provided at the bottom of the first electromagnet 28, and the connecting cylinder 29 is rotatably connected to the telescopic rod of the single-axis cylinder 27;

[0092] The second gear 30 is sleeved on the connecting cylinder 29, and the second gear 30 is fixedly connected to one end of the connecting cylinder 29 away from the first electromagnet 28;

[0093] The second rack 31 is slidably connected to the bottom of the feeding connecting plate 6, and the second rack 31 drives the connecting cylinder 29 to move upward through the single-axis cylinder 27, so that the second gear 30 meshes with the second rack 31;

[0094] The steering connecting plate 32 is arranged beside the loading 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 with a stop rod 33 in the up-and-down direction. A rectangular through hole 34 is provided on the stop rod 33, and a first inclined surface 35 is provided at the bottom of the rectangular through hole 34;

[0095] The push rod 36, one end of the push rod 36 is bent downward and fixedly connected to the pushing component 7;

[0096] The third mounting plate 37 is arranged below the stop rod 33. One side of the third mounting plate 37 is bent upward and fixedly connected to the bottom of the steering connecting plate 32;

[0097] The second guide rod 38 is inserted through the third mounting plate 37. One end of the second guide rod 38 is fixedly connected to the bottom of the stop rod 33, and the other end is restricted at the bottom of the third mounting plate 37 by a round block;

[0098] The second spring 39 is sleeved on the second guide rod 38, and both ends of the second spring 39 are respectively abutted against the stop rod 33 and the third mounting plate 37;

[0099] The insertion block 40 has a second inclined surface 41 adapted to the first inclined surface 35 at one end, and the other end is fixedly connected to the bottom of the feeding connecting plate 6 by bending. The insertion block 40 is located at a position on the side of the first electromagnet 28 away from the loading box 3;

[0100] The fixed block 42 is fixedly provided on one side of the loading box 3;

[0101] The third spring 43, one end of which is fixedly connected to the fixed block 42, and the other end is fixedly connected to the steering connecting plate 32.

[0102] 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.

[0104] A support plate 44 is fixedly mounted on a side of the punching machine 1 away from the charging box 3;

[0105] 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;

[0106] A support frame 46 is fixed on the top of the conveyor 45;

[0107] 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 .

[0108] For example, after the hinge punching is completed, the double-axis cylinder 47 drives the second electromagnet 48 to move to the top of the lower die placement groove. By energizing the second electromagnet 48, the hinge is sucked out. Then the double-axis cylinder 47 resets, causing the hinge to move to the top of the conveyor 45. By de-energizing the second electromagnet 48, the hinge falls onto the conveyor 45 and is transported to the next process, thus completing the material taking work after the hinge punching is completed.
