[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0022] First, combine Figures 1 to 6 A movable iron core riveting tool according to an embodiment of the present invention is described, which is used in a movable iron core riveting process and has a wide range of application scenarios.

[0023] like Figures 1 to 6As shown, the riveting tool for the movable iron core 3 of an embodiment of the present invention is used in the riveting process of the movable iron core 3. The movable iron core 3 comprises a riveting component 31 and a rubber component 32. The rubber component 32 is inserted into the end of the riveting component 31 to be riveted. In this embodiment, the tool comprises a riveting module 1 and a buffer module 2. The riveting module 1 performs riveting on the movable iron core 3; the buffer module 2 is connected to the riveting module 1 to buffer the riveting action of the riveting module 1. The buffer module 2 not only applies a preload to the movable iron core 3 before riveting, but also ensures a smoother riveting action.

[0024] Specifically, if Figures 1-3 As shown, in this embodiment, the riveting module 1 includes: an upper die 11, a rivet head 12, a pressing sleeve 13 and a guide sleeve 14; the rivet head 12 is connected to the upper die 11, and the upper die 11 drives the rivet head 12 to perform riveting; the guide sleeve 14 is connected to the upper die 11, and the guide sleeve 14 is sleeved on the moving iron core 3 during riveting, for limiting the position of the moving iron core 3 and preventing the moving iron core 3 from deforming during the riveting process; the pressing sleeve 13 is connected to the guide sleeve 14, and the pressing sleeve 13 can reciprocate in the guide sleeve 14, for pressing the rubber component 32 sleeved on the end of the moving iron core 3 to prevent the rubber component 32 from moving or failing to cling to the head of the riveted component 31 during the riveting process; the pressing sleeve 13 is sleeved on one end of the rivet head 12, and the rivet head 12 can reciprocate in the pressing sleeve 13. After the pressing sleeve 13 presses the rubber component 32, the rivet head 12 starts the riveting action, so that the rubber component 32 clings to the head of the riveted component 31 after riveting.

[0025] Further, if Figures 1-3 As shown, in this embodiment, the upper die 11 includes: a first die 111 and a second die 112 ; the first die 111 is connected to the second die 112 , and the second die 112 is connected to the rivet head 12 , and the first die 111 drives the rivet head 12 to move through the second die 112 .

[0026] Further, if Figures 1-3 As shown, in this embodiment, the riveting module 1 further includes: a pair of first guide rods 16, and the two ends of the second die 112 are respectively mounted on the pair of first guide rods 16. The second die 112 can reciprocate along the axial direction of the pair of first guide rods 16, adopting a sliding method, with a simple structure and easy implementation.

[0027] Further, if Figures 1-3 As shown, in this embodiment, it also includes: a limit column 4, which is arranged between the second die 112 and the guide sleeve 14, and the limit column 4 is threadedly connected to the upper end of the guide sleeve 14. The height of the limit column 4 is adjustable. When the guide sleeve 14 moves to the working position and stops, the second die 112 continues to move downward until it contacts the limit column 4. After contacting the second die 112, the limit column 4 is used to limit the second die 112 from continuing to move downward.

[0028] Further, if Figures 1-3 As shown, in this embodiment, the lower pressing die 15 is connected to the upper pressing die 11 to fix the movable iron core 3 and prevent the movable iron core 3 from moving.

[0029] Further, if Figures 1-3 As shown, in this embodiment, the first buffer component 21 is a spring, which is arranged between the guide sleeve 14 and the pressing sleeve 13, with one end connected to the guide sleeve 14 and the other end connected to the pressing sleeve 13, for buffering the riveting action of the pressing sleeve 13 and resetting after the riveting is completed.

[0030] Further, if Figures 1-3 As shown, in this embodiment, the second buffer component 22 is a spring, which is arranged between the guide sleeve 14 and the second die 112, with one end connected to the guide sleeve 14 and the other end connected to the second die 112, and is used for buffering after the guide sleeve 14 and the moving iron core 3 are fully in contact and for resetting the die.

[0031] Specifically, if Figures 1-3 As shown, in this embodiment, the third buffer component 23 is a pair of springs, and the third buffer component 23 is connected to the riveting module 1 for buffering the riveting action of the riveting module 1 and resetting the riveting module 1.

[0032] Further, if Figures 1-3 As shown, in this embodiment, it further includes: a pair of second guide rods 17 , and both ends of the riveting module 1 are respectively sleeved on the pair of second guide rods 17 , and the riveting module 1 can reciprocate along the axial direction of the pair of second guide rods 17 .

[0033] Further, if Figure 3 As shown, in this embodiment, the third buffer components 23 are respectively sleeved on a pair of second guide rods 17, which not only simplifies the structure but also prevents the third buffer components 23 from being bent during the buffering process.

[0034] Working principle: The press generates downward pressure on the upper die 11 of the movable iron core riveting tool (hereinafter referred to as the tool), and the upper die 11 moves downward vertically. At this time, the guide sleeve 14 is in radial contact with the lower die 15, forming an upper and lower die positioning action. When the inner end surface of the guide sleeve 14 contacts the upper surface of the lower die, resistance is generated. At this time, the guide sleeve 14 cannot move downward, and it produces a concentric positioning effect; at this time, the pressing sleeve 13 also touches the rubber component 32 of the movable iron core 3, and there is a downward pre-pressure. The first buffer component 21 connected to its upper part can make the pressing sleeve 13 produces a very natural soft pressure, ensuring that the movable iron core 3 will not bend, and the rubber component 32 is pressed against the end surface, making the end surfaces close together; the first pressing die 111 continues to move downward, and the second pressing die 112 carries the rivet head 12 downward, compressing the second buffer component 22, and generating relative movement with the guide sleeve 14 and the pressing sleeve 13, moving to the upper hole of the riveting component 31 of the movable iron core 3 to perform a flange riveting operation on it. Under the limiting action of the pre-adjusted limiting column 4, the second pressing die 112 and the rivet head 12 are limited downward to prevent them from moving further downward. In this way, a riveting effect is achieved, the riveting component 31 of the movable iron core 3 is riveted into place, and the movable iron core 3 will not bend or deform. After the riveting is completed, the press starts to retreat upward when the set time is reached. At the same time, the third buffer component 23 generates a rebound force on the upper part of the press frame, and the upper part will return. At this time, the second buffer component 22 and the first buffer component 21 also have a rebound effect on the corresponding components. The tooling reaches the initial state and is ready for the next riveting of the moving iron core 3.

[0035] Above, refer to Figures 1 to 6 The invention describes a riveting tool for a moving iron core according to an embodiment of the invention, which not only enables the head components to fit compactly during riveting, with good stamping effect and stable quality, but also solves the problem of the original single riveting process, ensuring that the riveting is in place and the parts are not deformed.
