[0022] Embodiment

[0023] When stamping a circular groove on the outer side of the fire damper frame 3, a slot forming machine needs to be used. However, the prior art generally uses a manual fixing clamp to fix the fire damper frame 3, and then uses a stamping device to punch a groove on the outer side of the fire damper frame 3. However, this greatly reduces the efficiency of the stamping groove.

[0024] Therefore, referring to Figs. 1-3 The utility model provides a slot forming machine for fire damper processing, which comprises a support table 1 and a fire damper frame 3. The fire damper frame 3 is placed on the top end of the support table 1. A pre-positioning part 2 is fixedly connected to the position near the rear wall of the top end of the support table 1. The pre-positioning part 2 is used for pre-positioning the fire damper frame 3. The outer side of the fire damper frame 3 is provided with a hydraulic cylinder 41 fixed on the top end of the support table 1 through an inverted L-shaped support plate 4. The telescopic end of the hydraulic cylinder 41 is fixedly connected with a stamping head 42.

[0025] The top end of the support table 1 is provided with two linkage type positioning parts 5 arranged symmetrically. The linkage type positioning parts 5 are connected with the telescopic ends of the two hydraulic cylinders 41 on the same side.

[0026] Further, asFigs. 1-3 As shown, it is worth noting that in order to facilitate the positioning of the fire damper frame 3, a positioning member 2 is arranged, which includes a limiting plate 21 attached to the outer side of the rear wall of the bottom end of the fire damper frame 3. The top end of the limiting plate 21 is fixedly connected with a lap plate 22. The front end of the lap plate 22 is provided with a lap arc-shaped bending part 23. The rear end of the lap plate 22 is provided with a weakening groove 24 at the connection with the top end of the limiting plate 21. The lap plate 22 is made of ABS plastic material.

[0027] The weakening groove 24 is arranged so that when the bottom end rear wall of the fire damper frame 3 is pressed against the lap arc-shaped bending part 23, the lap plate 22 can be lifted through the weakening groove 24, and at the same time, the limiting plate 21 can be used to facilitate the positioning of the fire damper frame 3 when the groove is pressed.

[0028] Further as shown in Figs. 1-3 In order to achieve synchronous downward movement of the four punching heads 42 and linkage clamping and fixing of the outer wall of the fire damper frame 3, a linkage positioning member 5 is arranged, which includes a positioning plate 51 arranged on one side of the fire damper frame 3. The vertical section of the positioning plate 51 is in a right triangle structure. The bottom end of the positioning plate 51 is provided with a cooperating groove 53 matched with the shape of the bottom of the fire damper frame 3. The bottom end of the positioning plate 51 is fixedly connected with a sliding seat 52 in a I-shaped structure. The sliding seat 52 is slidingly connected in a sliding groove arranged on the top end of the support table 1. Two transmission plates 54 are symmetrically arranged on the outer side of the inclined surface of the positioning plate 51. The vertical section of the transmission plate 54 is in a triangular structure. A transmission channel 55 in a hockey stick-shaped structure is arranged on the transmission plate 54. A transmission column 56 is movably connected in the transmission channel 55. The end of the transmission column 56 away from the transmission channel 55 is fixedly connected with the outer side of the telescopic end of the hydraulic cylinder 41 on the corresponding side through an L-shaped connecting rod 57.

[0029] The width of the transmission channel 55 is equal to the diameter of the transmission column 56.

[0030] In summary: when using the slotting press, the bottom end rear wall of the fire damper frame 3 is first inserted into the bottom of the lap plate 22, and the lap arc-shaped bending part 23 is driven to move upward and press the fire damper frame 3 through the setting of the weakening groove 24. In addition, the setting of the limiting plate 21 can make the fire damper frame 3 be pre-positioned first when the slot is punched, avoiding the problem of misalignment when the slot is punched. In addition, when the four hydraulic cylinders 41 drive the punching heads 42 to move downward synchronously, and the transmission column 56 and the L-shaped connecting rod 57 are set, the transmission column 56 moves downward in the transmission channel 55, and the two positioning plates 51 are relatively moved, so that the fire damper frame 3 can be further clamped and fixed, so that the four punching heads 42 can continue to move downward for punching, greatly improving the efficiency of the punching slot.
