[0045] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0046] The existing punching mechanism requires the coordination of three oil cylinders and two air cylinders to complete the clamping and punching of the aluminum guide rail. This punching mechanism is not only complex in structure and prone to damage to parts during the punching process, but also the components for receiving waste are often located directly below the punching mechanism. If the landing point of the waste is offset, it will cause problems such as material jamming, thereby increasing the difficulty of cleaning the waste.

[0047] Based on this, please refer to Figures 1 to 3A profile punching mechanism is proposed, comprising a blanking seat 1, a punching assembly 2, a Z-axis clamping assembly 3, a Y-axis clamping assembly 5 and a Y-axis limiting assembly 6 arranged opposite to the punching assembly 2; the punching assembly 2 is transmission-connected to the movable end of the Y-axis clamping assembly 5 and can move along the Y-axis direction; the blanking seat 1, the Y-axis limiting assembly 6, the Z-axis clamping assembly 3 and the Y-axis clamping assembly 5 together form a punching cavity 7 for clamping the profile to be punched; the punching direction of the punching assembly 2 and the blanking direction of the waste are both parallel to the Y-axis.

[0048] It can be understood that the profile punching mechanism of the present invention can complete the clamping of the profile only through the movable Z-axis clamping component 3 and the Y-axis clamping component 5, and the static Y-axis limit component 6 in terms of profile clamping. Compared with the existing punching mechanism, while reducing the number of active clamping devices, it can still ensure the clamping stability of the profile, and at the same time avoid the problem of severe deformation of the profile during the clamping process due to multi-point force.

[0049] In some embodiments, a first discharge hole 11 is provided on the blanking seat 1; a second discharge hole 61 is provided on the Y-axis limit assembly 6; the first discharge hole 11 and the second discharge hole 61 constitute a discharge channel; the punching end of the punching assembly 2 can move back and forth in the discharge channel; a waste collection box 12 is provided at one end of the blanking seat 1 along the Y-axis direction; the feed end of the discharge channel is arranged toward the punching cavity 7; the discharge end of the discharge channel is located in the material receiving area of ​​the waste collection box 12. By providing a discharge channel on the punching path of the punching component 2, not only can the punching component 2 further drive the waste to the discharge end of the discharge channel after processing the incision on the profile until the waste falls into the waste collection box 12 to prevent the material from getting stuck, but the design can also place the waste collection box 12 in the Y-axis direction, so that the staff can directly remove the waste from the waste collection box 12, eliminating the tedious operation of taking out the waste collection box 12 from under the punching mechanism before cleaning.

[0050] In some embodiments, the movable end of the Y-axis clamping assembly 5 is further provided with a guide assembly 51; the punching assembly 2 is connected to the movable end of the Y-axis clamping assembly 5 via the guide assembly 51. This design can improve the movement accuracy of the punching assembly 2 and prevent deviations in the Y-axis clamping assembly 5 when driving the punching assembly 2 to move back and forth along the Y-axis, thereby affecting the punching accuracy of the profile.

[0051] In some embodiments, a clamping member 511 is provided on the guide assembly 51; the clamping member 511 is positioned opposite the Y-axis clamping assembly 5; the blanking base 1, the Y-axis limit assembly 6, the Z-axis clamping assembly 3, and the clamping member 511 together form a punching cavity 7 for clamping the profile to be punched; the punching assembly 2 includes a punching blade 21 connected to its punching end; the punching end drives the punching blade 21 to slide on the guide assembly 51; the punching end can drive the punching blade 21 into the punching cavity 7. This design further defines the structure of the punching assembly 2. The cooperation between the punching end and the guide assembly 51 ensures the stability of the punching blade 21 during movement, thereby effectively ensuring the accuracy of profile punching.

[0052] In some embodiments, the clamping member 511 is provided with an escape notch 512 along the Y-axis; the punching end of the punching assembly 2 can enter the punching cavity 7 through the escape notch 512. Since the notch to be punched in the profile is within the clamping range of the clamping member 511, the provision of the escape notch 512 on the clamping member 511 to facilitate the movement of the punching end allows the profile to be punched without affecting the stability of the profile clamping, thereby avoiding interference between the punching assembly 2 and the clamping member 511 that could affect the normal punching process.

[0053] In some embodiments, a stopper 8 is provided along the movement path of the Y-axis clamping assembly 5; the stopper 8 is positioned between the guide assembly 51 and the Y-axis stopper 6; and the stopper 8 is detachably connected to the blanking base 1. During the clamping process, the stopper 8 prevents the Y-axis clamping assembly 5 from excessively moving and pressing the profile, which could cause irreversible deformation. Furthermore, the detachable connection between the stopper 8 and the blanking base 1 allows operators to conveniently replace the stopper 8 based on the profile being processed, thereby expanding the applicability of the punching mechanism.

[0054] In some embodiments, the aforementioned profile punching mechanism further includes an X-axis stop assembly 4; the blanking base 1, the Y-axis stop assembly 6, the Z-axis clamping assembly 3, the X-axis stop assembly 4, and the Y-axis clamping assembly 5 together form a punching cavity 7 for clamping the profile to be punched. The further provision of the X-axis stop assembly 4 facilitates punching positioning, ensuring the precise placement of the notch punched in the profile and preventing the positioning accuracy of subsequent processes from being affected by the varying notch positions.

[0055] In some embodiments, the Y-axis limit assembly 6 includes a floating part 62, a support part 63 and an elastic part 64; the floating part 62 is connected to the support part 63 through the elastic part 64; a clamping surface 13 is provided on the blanking seat 1; the clamping surface 13 is arranged opposite to the floating part 62; the elastic part 64 can drive the floating part 62 to move parallel to the punching direction, thereby creating a gap between the floating part 62 and the clamping surface 13, so as to facilitate the placement of the profile to be processed; under the action of the Y-axis clamping assembly 5, the gap between the floating part 62 and the clamping surface 13 gradually decreases, so that the relevant clamping parts can clamp the profile to be processed in the Y-axis direction; when the punching action is completed and the pressure in the Y-axis direction is released, the elastic part 64 can drive the floating part 62 to move parallel to the punching direction again, thereby creating a gap between the floating part 62 and the clamping surface 13 again, so that the staff can take out the punched profile.
