Description

Technical Field

[0001] This application relates to the field of feeding for stamping machines, particularly to the feeding mechanism of a hook stamping machine. Background Art

[0002] The stamping process of hooks is a processing method that plastically deforms metal sheets through a die and a press to obtain a predetermined shape and size. When stamping hooks, a feeding mechanism is required to continuously supply metal sheets to the stamping die to improve the efficiency of stamping processing.

[0003] When the traditional feeding mechanism of a hook stamping machine is in use, the hook coil to be stamped is often sleeved on the expansion and contraction material supporting component through a crane or a hoist. The expansion and contraction of the expansion and contraction material supporting component plays a supporting role for the coil. To prevent the coil from moving during the unwinding process, two guide plates are usually used to limit and fix the position of the coil. The traditional guide plates are fixed to the expansion and contraction material supporting component by bolts, and the distance between the guide plates can only be adjusted according to the pitch of the threaded holes on the expansion and contraction material supporting component. Since the hole pitch is fixed, when dealing with coils with a large width variation or coils whose width is not within the preset hole pitch range, the traditional guide plates may not provide appropriate support or guidance. To adapt to coils of different widths, manual adjustment or addition of auxiliary accessories such as gaskets and adapters is required. This process is both time-consuming and laborious, increasing the production preparation time and operation complexity, and thus affecting the processing accuracy and efficiency. To solve the above problems, a feeding mechanism for a hook stamping machine is now proposed.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

Detailed implementation manners

[0026] The following further elaborates on this application in conjunction with the attached Figures 1-7 for a more detailed description.

[0027] The application embodiment discloses a loading mechanism of a hook stamping machine. Referring to Figures 1-7 , the loading mechanism of the hook stamping machine includes a machine base 1, on which an expansion and contraction material supporting component 2 for supporting the hook coil 101 to be punched is provided. On the expansion and contraction material supporting component 2, a matching guide plate 3 and an adjustable guide plate 5 for fixing the hook coil 101 to be punched and a moving component for driving the matching guide plate 3 and the adjustable guide plate 5 to move are provided. The matching guide plate 3 and the adjustable guide plate 5 can approach or move away from each other simultaneously;

[0028] By adopting the above technical solution, the hook coil 101 to be punched is placed on the expansion and contraction material supporting component 2, and under the action of the moving component, the matching guide plate 3 and the adjustable guide plate 5 can approach or move away from each other simultaneously, enabling more flexible adjustment for hook coils 101 to be punched with different widths without adding additional accessories.

[0029] Referring to Figure 1 ,4 Moreover, an adjusting component 4 for adjusting the angle of the adjustable guide plate 5 is also provided on the expansion and contraction material supporting component 2;

[0030] It should be noted that the rotation angle of the adjusting component 4 is such that when viewed from Figure 1 a certain perspective, it can be rotated 90 degrees clockwise to be parallel to the mating guide plate 3;

[0031] By adopting the above technical solution, before the hook coil material 101 to be stamped is placed on the expansion and contraction material supporting component 2, the adjustable guide plate 5 is in a horizontal state. When the hook coil material 101 to be stamped is placed on the expansion and contraction material supporting component 2, the adjusting component 4 is rotated to make the adjustable guide plate 5 parallel to the mating guide plate 3. The adjustment of the adjustable guide plate 5 by the adjusting component 4 facilitates the feeding of the hook coil material 101 to be stamped.

[0032] Referring to Figure 1 and 5 , the expansion and contraction material supporting component 2 includes an expansion and contraction part and a material supporting part;

[0033] The material supporting part includes a support frame 21, a support shaft 22, a first limit block 27, and a material supporting plate 28. The support frame 21 is fixed on the machine base 1. The support shaft 22 rotates on the support frame 21. The material supporting plate 28 is connected to the support shaft 22 through the expansion and contraction part. The first limit block 27 is fixed on the material supporting plate 28. The moving component is located on the material supporting plate 28. The mating guide plate 3 is sleeved on the material supporting plate 28. The adjustable guide plate 5 is sleeved on the material supporting plate 28 through the adjusting component 4;

[0034] The expansion and contraction part includes a threaded cylinder 23, a rotating cylinder 24, a fixed connecting rod 25, and a rotating connecting rod 26. The threaded cylinder 23 is threadedly connected to the support shaft 22. The rotating cylinder 24 is slidably connected to the support shaft 22. The fixed connecting rod 25 is fixed between the threaded cylinder 23 and the rotating cylinder 24. Both ends of the rotating connecting rod 26 are rotatably connected to the fixed connecting rod 25 and the material supporting plate 28 respectively;

[0035] One end of the support shaft 22 is fixed with a square block;

[0036] The support frame 21 is provided with a limit groove. The first limit block 27 passes through the limit groove and has a clearance fit with the support frame 21

[0037] It should be noted that the support frame 21 is fixed to the machine base 1 through a rotating shaft, and the other end of the rotating shaft is fixed with a motor (not shown in the figure);

[0038] By adopting the above technical solution, during use, the to-be-punched hook coil 101 is sleeved and placed on the stock plate 28. Use a wrench to turn the square block to make the support shaft 22 rotate. Under the thread fit between the threaded cylinder 23 and the support shaft 22, the threaded cylinder 23 approaches the support frame 21. Driven by the support of the fixed connecting rod 25, the rotating cylinder 24 moves towards the support frame 21 along the support shaft 22. At this time, the rotating connecting rod 26 rotates, and the stock plate 28 expands around along the limiting groove opened on the support frame 21 under the limitation of the first limiting block 27, so that the surface of the stock plate 28 closely adheres to the inner wall of the drum of the to-be-punched hook coil 101, thereby playing a supporting role for the to-be-punched hook coil 101. Start the motor to drive the support frame 21 and the to-be-punched hook coil 101 thereon to rotate, thereby continuously feeding the hook punching machine.

[0039] Referring to Figure 6 , the moving assembly includes a first chute 6, a bidirectional screw 7, and a knob 8. The first chute 6 is opened on the stock plate 28. The bidirectional screw 7 rotates in the first chute 6. The knob 8 is fixed at one end of the bidirectional screw 7. The mating guide plate 3 is threadedly connected to the bidirectional screw 7. The adjustable guide plate 5 is threadedly connected to the bidirectional screw 7 through the adjusting assembly 4. A second chute 9 is also opened at the bottom of the stock plate 28;

[0040] It should be noted that half of the bidirectional screw 7 has a left-handed thread and the other half has a right-handed thread. The mating guide plate 3 is threadedly connected to half of the left-handed thread of the bidirectional screw 7. The adjustable guide plate 5 is threadedly connected to half of the right-handed thread of the bidirectional screw 7 through the adjusting assembly 4. When the bidirectional screw 7 rotates forward, the mating guide plate 3 and the adjustable guide plate 5 approach each other, and when it rotates backward, the mating guide plate 3 and the adjustable guide plate 5 move away from each other;

[0041] It should be further noted that the setting of the second chute 9 facilitates the smoother adjustment of the mating guide plate 3 and the adjustable guide plate 5 on the stock plate 28;

[0042] By adopting the above technical solution, turning the knob 8 makes the bidirectional screw 7 rotate, thereby realizing the simultaneous approach or separation of the mating guide plate 3 and the adjustable guide plate 5.

[0043] Referring to Figure 4 , the adjusting assembly 4 includes a sliding hoop 41, a support column 42, a swing rod 43, a second limiting block 44, and a limiting pin 45. The sliding hoop 41 is sleeved on the stock plate 28. The sliding hoop 41 is threadedly connected to the bidirectional screw 7. The support column 42 is fixed on the sliding hoop 41. One end of the swing rod 43 is rotatably connected to the support column 42. The other end of the swing rod 43 is fixed to the adjustable guide plate 5. The second limiting block 44 is fixed on the sliding hoop 41. The limiting pin 45 passes through the swing rod 43 and is threadedly engaged with the second limiting block 44;

[0044] It should be noted that the sliding hoop 41 is threadedly connected to half of the right-handed thread of the bidirectional screw 7;

[0045] It should be further noted that the limit pin 45 is also in threaded fit with the swing rod 43;

[0046] By adopting the above technical solution, when the adjustable guide plate 5 is in a horizontal state, the limit pin 45 and the second limit block 44 are in a disengaged state. When the inner wall of the reel of the hook coil material 101 to be punched is in close contact with the surface of the stock plate 28, the swing rod 43 is toggled to make the adjustable guide plate 5 parallel to the mating guide plate 3. At this time, the limit pin 45 is screwed into the second limit block 44 to limit the position of the adjustable guide plate 5.

[0047] The implementation principle of the feeding mechanism of the hook punching machine in the embodiment of the present application is as follows: Before the hook coil material 101 to be punched is placed on the stock plate 28, the adjustable guide plate 5 is in a horizontal state. When the hook coil material 101 to be punched is placed on the stock plate 28, a wrench is used to turn the square block, thereby rotating the support shaft 22. The threaded cylinder 23 moves closer to the support frame 21, driving the rotating cylinder 24 to move closer to the support frame 21 together. The stock plate 28 expands outwards, so that the surface of the stock plate 28 is in close contact with the inner wall of the reel of the hook coil material 101 to be punched. The swing rod 43 is toggled to make the adjustable guide plate 5 parallel to the mating guide plate 3. At this time, the limit pin 45 is screwed into the second limit block 44 to limit the position of the adjustable guide plate 5. The knob 8 is rotated forward to make the bidirectional screw rod 7 rotate, thereby realizing that the mating guide plate 3 and the adjustable guide plate 5 approach each other simultaneously to both sides of the hook coil material 101 to be punched. The end of the hook coil material 101 to be punched is placed at the feeding port of the hook punching machine, and the motor is started to drive the support frame 21 and the hook coil material 101 thereon to rotate, thereby continuously feeding the hook punching machine. When changing the material, the above steps can be repeated.
