Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a device for manufacturing a metal air duct sealing gasket. Background Art

[0002] Metal duct installation is often involved in mechanical and electrical installation projects. The connection methods of metal ducts are divided into flange connection, angle iron connection, bayonet connection, etc. These connection methods all require the use of sealing gaskets to seal the connection positions. The installation quality of metal ducts (especially sealing performance) seriously affects the subsequent acceptance and use effect.

[0003] At present, most metal air duct installations use sealing gaskets to enhance the sealing performance. Before the metal air duct is connected, the sealing gaskets are adjusted to the right position so that the sealing gaskets at the four corners of the metal air duct are vertically aligned, and the two sections of the metal air duct are connected and fixed with the help of tape. Using this sealing method, the sealing effect of the long side and the short side of the metal air duct connection is better, but if the connection of the sealing gaskets at the four corners of the metal air duct is slightly deviated, air leakage will occur. To this end, the inventor proposes a metal air duct sealing gasket manufacturing device. Utility Model Content

[0004] The purpose of the present application is to provide a device for making metal air duct sealing gaskets, which can cut mortise and tenon joints out of the sealing gaskets, so that mortise and tenon joints are formed between the sealing gaskets, thereby enhancing the sealing performance of the metal air duct.

[0005] The embodiment of the present application is implemented as follows:

[0006] The present application provides a device for manufacturing a metal air duct sealing gasket, comprising a support plate fixedly connected to a clamp head of a clamp body, wherein a mounting block is fixedly connected to an inner side wall of one of the support plates, blades arranged in a V shape are inserted on adjacent two side walls of the mounting block, a positioning plate inserted into the interior of the mounting block is fixedly connected to the blade, a slider is slidably clamped inside the mounting block, the slider is rotatably connected to an adjustment bolt screwed on the support plate, a wedge block is fixedly connected to an end face of the slider, and the wedge block is inserted into a positioning groove on the corresponding positioning plate.

[0007] The present application drives the slider to slide inside the mounting block by rotating the adjusting bolt, so that the wedge block can be inserted into the positioning groove on the positioning plate. The wedge block pushes the positioning plate to make the blade tightly fixed to the side wall of the mounting block. By closing the clamp body, the blade can be used to cut a V-shaped mortise and tenon interface on the sealing gasket, so that the sealing gaskets form a mortise and tenon joint, thereby enhancing the sealing performance of the metal air duct.

[0035] Example 1

[0036] See also Figure 1-Figure 4 This embodiment provides a metal air duct sealing gasket manufacturing device to solve the problem of poor sealing performance of the existing metal air duct due to the easy docking deviation between the sealing gaskets.

[0037] In this embodiment, the metal duct sealing gasket manufacturing device includes a support plate 20 fixedly connected to the clamp head 11 of the clamp body 10, wherein a mounting block 21 is fixedly connected to the inner side wall of one of the support plates 20, and blades 30 arranged in a V shape are inserted on the adjacent two side walls of the mounting block 21, and a positioning plate 31 inserted into the interior of the mounting block 21 is fixedly connected to the blade 30, and a slider 22 is slidably clamped inside the mounting block 21, and the slider 22 is rotatably connected to the adjusting bolt 23 screwed on the support plate 20, and a wedge block 221 is fixedly connected to the end face of the slider 22, and the wedge block 221 is inserted into the corresponding positioning groove 311 on the positioning plate 31.

[0038] In this embodiment, the slider 22 is driven to slide inside the mounting block 21 by rotating the adjusting bolt 23, so that the wedge block 221 can be inserted into the positioning groove 311 on the positioning plate 31. The wedge block 221 pushes the positioning plate 31 to make the blade 30 tightly fixed to the side wall of the mounting block 21. By closing the clamp body 10, the blade 30 can cut a V-shaped mortise and tenon interface on the sealing gasket, so that the sealing gaskets form a mortise and tenon joint, thereby enhancing the sealing performance of the metal air duct.

[0039] It should be noted that a support plate 20 is bolted to each of the two clamp heads 11 of the clamp body 10. The closing of the clamp body 10 can make the two support plates 20 parallel. A triangular mounting block 21 is welded on the inner wall of the upper support plate 20, and two mounting blocks 21 are arranged at intervals on the support plate 20. A blade 30 is provided on the adjacent two side walls of each mounting block 21, and the two blades 30 are arranged in a V-shape on the mounting block 21. When the clamp body 10 is closed, the blade of the blade 30 abuts against the inner wall of the lower support plate 20, and a V-shaped mortise and tenon joint can be cut on the sealing gasket placed on the lower support plate 20. By forming a mortise and tenon joint between the two adjacent sealing gaskets, the neatness of the joint between the sealing gaskets can be improved, thereby enhancing the sealing performance of the metal air duct.

[0040] In addition, the mounting block 21 is provided with a triangular mounting cavity 211 adapted to its shape, and the triangular slider 22 is adaptively snapped into the mounting cavity 211, and the slider 22 can slide along the extension direction of the mounting cavity 211, and a wedge block 221 is fixedly connected to the lower end surface of the slider 22, and the wedge block 221 maintains a one-to-one correspondence with the blade 30, and a through hole 222 is provided in the middle position of the slider 22, and the adjusting bolt 23 is screwed on the upper support plate 20, and the lower end of the adjusting bolt 23 passes through the through hole 222 on the slider 22, and locking nuts (not shown in the figure) are screwed on the adjusting bolt 23 on the upper and lower sides of the slider 22, and the slider 22 is arranged as a whole between the two locking nuts, and the two locking nuts are used to lock the slider 22 on the adjusting bolt 23, and form a rotational connection between the adjusting bolt 23 and the slider 22, and when the adjusting bolt 23 is screwed in or out on the support plate 20, it can drive the slider 22 to slide inside the mounting cavity 211.

[0041] In addition, a rectangular slot is provided on the side wall of the mounting block 21, the positioning plate 31 is welded to the side wall of the blade 30, and the positioning plate 31 and the blade 30 are arranged vertically, the positioning plate 31 is inserted into the slot in an adaptive manner, and the inner end of the positioning plate 31 extends into the mounting cavity 211, the positioning groove 311 is formed on the positioning plate 31, and the positioning groove 311 is configured to be a rectangle that is adapted to the outer shape of the positioning plate 31, a portion of the positioning groove 311 extends into the mounting cavity 211, and the positioning groove 311 is aligned with the wedge block 2 21, the width of the wedge block 221 is equal to that of the positioning groove 311, the wedge block 221 is arranged in a one-to-one correspondence with the positioning groove 311, and the wedge block 211 is inserted into the positioning groove 311. As the adjusting bolt 23 rotates, the slider 22 continuously approaches the positioning plate 31, and the wedge block 221 is continuously inserted into the positioning groove 311. The thickness of the wedge block 221 increases from the outer end toward the slider 22, so the wedge block 221 will push the positioning plate 31 as a whole toward the inside of the mounting cavity 211, so that the blade 30 is fixed on the side wall of the mounting block 21 as a whole.

[0042] It should be noted that the adjusting bolt 23 as a whole is arranged perpendicularly to the supporting plate 20 , and the axis of the adjusting bolt 23 is arranged perpendicularly to the positioning plate 31 .

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
