DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Reference Figure 1 The shown device is a striking device for bearing seat production, comprising a material guide frame having an eight-shaped feeding section 1 and a material guide section 3 arranged obliquely downward, and also comprising an automatic striking unit 4 installed on the material guide frame. The automatic striking unit 4 automatically strikes the opening at the upper end of the bearing seat 5 that moves to the striking position, so that the punched waste is separated from the bearing seat 5.

[0020] As a preferred implementation in this embodiment, Figure 2 and Figure 3 As shown, the automatic knocking unit 4 includes two mounting plates 41 mounted on the guide frame and arranged opposite to each other, wherein a contact block 42 with a direct triangular structure is slidably arranged in the inner cavity of one of the mounting plates 41, and a part of the inclined surface end of the contact block 42 is located on the sliding path of the bearing seat 5, and the contact block 42 is connected to the inner wall of the mounting plate 41 through a spring 46, and a second rack 44 is slidably arranged in the inner cavity of the mounting plate 41, and the second rack 44 is gear-connected with the first rack 43 through a transmission gear 45, and the first rack 43 is fixed at the right angle end of the contact block 42. On the surface, a movable rod 47 is rotatably set on the second rack 44, and the upper end of the movable rod 47 is rotatably connected to the upper end of the driving rod 48, and the driving rod 48 is rotatably connected to the support plate 49 installed on the mounting plate 41 through a pin shaft 410, and the pin shaft 410 is set close to the lower end of the driving rod 48, and an arc-shaped gear rod 412 is fixed to the lower end of the driving rod 48, and the arc-shaped gear rod 412 is gear-connected with the impact gear column 413, and the upper end of the impact gear column 413 slides through the limit plate 411, and the limit plate 411 is installed at the upper ends of the two mounting plates 41.

[0021] The bearing seat is pushed onto the guide section 3 and slides along its inclined surface. The speed of the sliding bearing seat 5 will increase under the action of gravity. The fast-moving bearing seat 5 will be squeezed out and pressed against the contact block 42, so that the contact block 42 moves toward the inner cavity of the mounting plate 41. The first rack 43 is geared with the second rack 44 through the transmission gear 45, so that the lower end of the movable rod 47 can move close to the bearing seat 5. The movable rod 47 drives the driving rod 48 to rotate downward with the pin shaft 410 as a circle. The arc-shaped gear rod 412 drives the impact gear column 413 to knock against the stamping waste in the hole of the bearing seat 5, so that the stamping waste can be removed. After the knocking is completed, the moving bearing seat 5 is separated from the contact block 42, and the impact tooth 413 is restored to its original position through the elastic force of the spring 46, and the bearing seat 5 continues to slide with its remaining kinetic energy and finally enters the material receiving box (its stamping waste is also sent to the material receiving box by the bearing seat). The automatic knocking unit converts the gravitational potential energy of the bearing seat 5 into the kinetic energy of the bearing seat 5 through the inclined guide section 3, and then uses this part of the kinetic energy as a power source to knock and remove the stamping waste in the hole of the bearing seat 5. Regardless of whether there is punching waste in the hole, the bearing seat 5 needs to slide through the knocking position, thereby avoiding screening. At the same time, it automatically performs the knocking operation.

[0022] It should be noted that the pin shaft 410 is arranged close to the lower end of the driving rod 48, so that the driving rod 48, the movable rod 47, and the impact tooth column 413 constitute a labor-saving lever. By applying a small upward force to the long force end of the driving rod 48, a large force will be applied to the lower end of the driving rod 48 to drive the impact tooth column 413 to move downward, which is conducive to knocking out the stubborn punching waste in the bearing seat.

[0023] As a preferred implementation in this embodiment, as shown in FIG. Figure 3 As shown, a power-assisting unit is also included to assist the bearing seat 5 in accelerating its downward movement.

[0024] As a preferred implementation in this embodiment, Figure 3 As shown, the power assist unit is configured as a magnet 6 , and the magnet 6 is disposed in a groove of the mounting plate 41 .

[0025] The magnetic force of the magnet 6 can generate suction on the bearing seat 5, and the sliding bearing seat 5 can be accelerated so that it has enough kinetic energy to pass through the knocking position and finally enter the receiving trough.

[0026] It should be noted that, first, there is no material guide section at the position corresponding to the position where the magnet 6 is set, that is, the material guide end is between the positions of the magnet 6. When it moves to the position of the magnet 6, the bearing seat 5 is in a suspended state, and the magnet 6 cannot attract the bearing seat 5, thereby causing the bearing seat 5 to move into the material receiving box. If there is no material guide section at the position corresponding to the position where the magnet 6 is set, the magnetism of the magnet 6 can be correspondingly improved, and the bearing seat 5 can be further accelerated so that it has enough kinetic energy to pass through the knocking position; second, in order to prevent the magnetic force generated by the magnet 6 from affecting other components, a magnetic isolation coating can be provided on the outer surface of the affected component.

[0027] As a preferred implementation in this embodiment, Figure 1 As shown, a material discharge opening 2 is provided on the material guiding section 3 .

[0028] A material receiving bucket can be placed at the knocking position, which is specially used to receive the fallen stamping waste, and the setting of the material discharge opening 2 can reduce the contact area with the bottom of the bearing seat 5, thereby reducing friction and increasing the sliding speed of the bearing seat 5.

[0029] It should be noted that the material discharge opening 2 is set as large as possible to reduce the contact area with the bearing seat 5 as much as possible.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
