Description

Technical Field

[0001] The utility model belongs to the technical field of air duct processing, and particularly relates to a steel plate air duct shearing machine. Background Art

[0002] Ducts are piping systems used for air transportation and distribution. They come in two types: composite and inorganic. Ducts can also be categorized by cross-sectional shape and material. Metal ducts are made from various metal materials, commonly including galvanized steel and stainless steel. In the fabrication workshop, the required steel plate thickness is selected based on the pre-assembled duct material list. Shears are then used to cut the steel to the appropriate size to facilitate subsequent processing, such as chamfering and flanges.

[0003] When the shearing machine of the prior art cuts multiple groups of air duct steel plates at the same time, the steel plates are placed on the feed table, and it is not easy for them to fit tightly together, resulting in the steel plates being easily misaligned during pushing and cutting, causing the cuts to be tilted and reworked, which delays work efficiency. In addition, the steel plates used to make air ducts are generally thin, and the curled state during transportation causes some steel plates to still be slightly raised during processing and cutting, requiring the operator to press before pushing the material, which is time-consuming and labor-intensive.

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 3-Figure 4As shown, a steel plate air duct shearing machine includes a connecting rod 116 and a cutting frame 101 fixedly assembled on the top of the feed table 1. The two ends of the top of the feed table 1 and one side of the cutting frame 101 are fixedly connected with a horizontal plate 102. One side of the cutting frame 101 and above the horizontal plate 102 are rotatably connected with a rotating rod 108. The connecting rod 116 is fixedly connected to one side of the rotating rod 108. The two sides of the cutting frame 101 are symmetrically provided with arc grooves 106. The cutting frame 101 is slidably connected to the adapter 103 through the arc groove 106. The outer wall of the cutting frame 101 and one end of the arc groove 106 are fixedly connected with a fixed plate 104. The fixed plate 104 is elastically bent. The spring 105 is elastically connected to the adapter 103, and the middle part of the adapter 103 is rotatably connected to the connecting handle 107, and one end of the connecting handle 107 is rotatably connected to the connecting rod 116. A groove 123 is provided at one end of the horizontal plate 102, and a support rod 124 is elastically and telescopically assembled inside the groove 123. The top of the support rod 124 is fixedly connected to a ring 125, and the ring 125 is movably nested in one end of the rotating rod 108. A sliding frame 2 117 is fixedly connected between the two rotating rods 108. The outer wall of the rotating rod 108 and located on one side of the connecting rod 116 are fixedly connected to a vertical plate 109, and a vertical clamping mechanism is symmetrically assembled between the two vertical plates 109.

[0022] According to the above structure, the sliding frame 2 117 is lifted upward, and the rotating rod 108 rotates accordingly, and drives the vertical plate 109 and the vertical pressing mechanism to be lifted together. The rotating rod 108 drives the connecting handle 107 to move through the connecting rod 116, and the connecting handle 107 pushes the adapter 103 to slide along the arc groove 106, and the bending spring 105 contracts accordingly. At this time, the multiple steel plates that need to be cut can be stacked on the top of the feed table 1. After adjusting the width of the vertical pressing mechanism according to the number of steel plates, pull the support rod 124 to drive the ring 125 to move to one end of the groove 123, and then press down the sliding frame 2 117 according to the above steps, and the rotating rod 108 and other components rotate accordingly. The bottom of the vertical plate 109 is fitted with the horizontal plate 102, and then the support rod 124 is loosened to allow the ring 125 to be embedded in the rotating rod 108, fixing the rotating rod 108 to prevent it from rotating.

[0023] Refer to the attached Figures 1-4The middle of the sliding frame 117 is provided with a sliding groove 118, and the inner wall of the sliding groove 118 is symmetrically slidably connected to the sliding rod 119. One end of the sliding rod 119 is located above the sliding frame 117 and is threadedly connected to a nut 120. The top of the sliding frame 117 is fixed with a plurality of convex grooves 121 at equal distances. The bottom of the sliding rod 119 is fixedly connected to a clamping plate 122 on one side of the horizontal plate 102. The vertical pressing mechanism includes a sliding frame 110 symmetrically fixedly connected to both ends of the vertical plate 109. A plurality of sliding rods 112 are equidistantly slidably arranged between the two sliding frames 110, and connecting pins 114 are fixedly connected at both ends of the sliding rod 112. A connecting handle 113 is movably hinged between the two sliding rods 112 through the connecting pins 114. Through grooves 111 for sliding of the connecting pins 114 are provided on both sides of the sliding frame 110, and rollers 115 are fixedly assembled at the bottom of the sliding rod 112. The two splints 122 are respectively fixedly connected to the connecting pins 114 at both ends of the sliding frame 110.

[0024] According to the above structure, before the ring 125 is embedded in the rotating rod 108, the sliding rod 119 is moved to adjust the position of a clamping plate 122 according to the width of the plurality of steel plates, so that the steel plate is clamped. The clamping plate 122 drives the sliding rod 112 to slide in the sliding frame 110 through the connecting pin 114, and the connecting handle 113 is folded into the sliding rod 112, so that the width of the plurality of sliding rods 112 is the same as the width between the two clamping plates 122 to adapt to the width of the plurality of steel plates. When the vertical pressing mechanism rotates with the rotating rod 108 and the roller 115 is in contact with the steel plate, the ring 125 is embedded in the rotating rod 108. 8. The roller 115 presses the steel plate without affecting its movement. The nut 120 is rotated to make it fit with the top of the sliding frame 117, so that the position of the clamping plate 122 is fixed, and the convex pattern 121 can increase the friction between the nut 120 and the sliding frame 117. The utility model drives the sliding rod 112 to move through the movement of the clamping plate 122. When multiple steel plates are stacked on the feed table 1, different numbers of steel plates can be vertically compressed and horizontally clamped to prevent the steel plates from being misplaced during pushing and causing the incision to be tilted, thereby avoiding rework and delaying work efficiency. At the same time, the slightly curved steel plates can be straightened during cutting without the need for manual alignment and pressing, saving time and effort.

[0025] The working principle of the present invention is as follows: the sliding frame 117 is lifted upward, the rotating rod 108 rotates accordingly, and drives the vertical plate 109 and the vertical pressing mechanism to be lifted together, the rotating rod 108 drives the connecting handle 107 to move through the connecting rod 116, and the connecting handle 107 pushes the adapter 103 to slide along the arc groove 106, and the bending spring 105 contracts accordingly, At this time, multiple steel plates that need to be cut can be stacked on the top of the feed table 1, and after adjusting the width of the vertical pressing mechanism according to the number of steel plates, the support rod 124 is pulled to drive the ring 125 to move to one end of the groove 123, and then the sliding frame 117 is pressed down according to the above steps, the rotating rod 108 and other components rotate accordingly, and the bottom of the vertical plate 109 is fitted with the horizontal plate 102, and then the support rod 124 is loosened to allow the ring 125 to be embedded in the rotating rod 108, fixing the rotating rod 108 to prevent it from rotating; 25 Before being embedded in the rotating rod 108, according to the width of several steel plates, the sliding rod 2 119 is moved to adjust the position of a clamping plate 122 so that it clamps the steel plate. The clamping plate 122 drives the sliding rod 112 to slide in the sliding frame 110 through the connecting pin 114, and the connecting handle 2 113 is folded into the sliding rod 112, so that the width of the connection between several sliding rods 112 is the same as the width between the two clamping plates 122 to adapt to the width of multiple steel plates. When the vertical pressing mechanism rotates with the rotating rod 108 and the roller 115 is in contact with the steel plate, the ring 125 is embedded in the rotating rod 108, and the roller 115 presses the steel plate without affecting the movement of the steel plate. The nut 120 is rotated to make it fit with the top of the sliding frame 2 117, so that the position of the clamping plate 122 is fixed, and the convex pattern 121 can increase the friction between the nut 120 and the sliding frame 2 117.

[0026] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
