Description

Technical Field

[0001] This utility model relates to the field of sheet metal trimming structure technology, and in particular to an adaptive sheet metal trimming structure. Background Technology

[0002] In the field of sheet metal processing, edge trimming is a crucial process for ensuring the quality of finished sheet metal products. Its main function is to remove burrs and rough edges generated after cutting, correct the dimensional accuracy of the sheet metal edges, and give the edges a smooth and even appearance to meet the needs of subsequent assembly and decoration. Currently, sheet metal trimming mainly relies on manual or mechanical trimming methods. To improve efficiency, mechanical trimming structures are gradually becoming the mainstream, commonly including handheld trimming machines and benchtop trimming equipment. However, existing mechanical trimming structures still have many shortcomings in practical applications: on the one hand, they cannot adjust the position of the trimming structure to adapt to sheet metal of different widths, and the width of the trimmed sheet metal has errors; furthermore, the trimmed edge material accumulates directly under the processing rack, making collection inconvenient. Therefore, we propose an adaptive sheet metal trimming structure. Utility Model Content

[0003] The main objective of this invention is to provide an adaptive sheet metal trimming structure that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adaptive sheet metal trimming structure includes a processing frame. A collecting roller is movably mounted on the front of the processing frame via a bearing seat. U-shaped slots are installed on both sides of the front of the processing frame. A first bearing-integrated traction roller is fitted between the two U-shaped slots. A guide roller is movably mounted on the top of the processing frame via a bearing seat. A reduction motor is installed below the processing frame. A trimming mechanism is fixedly mounted on the processing frame above the reduction motor. A second bearing-integrated traction roller is installed on the inner side of the processing frame below and behind the guide roller. A third bearing-integrated traction roller is installed on the inner side of the processing frame behind the trimming mechanism.

[0005] Preferably, the first bearing-integrated traction roller is engaged into the U-shaped groove by its own weight at both ends and comes into contact with the collecting roller.

[0006] Preferably, the extended end of the geared motor is equipped with a No. 4 pulley, and the two ends of the guide roller are respectively connected to a No. 3 pulley and a No. 2 pulley. The No. 4 pulley is movably connected to the No. 3 pulley through a second belt.

[0007] Preferably, one end of the collecting roller is connected to a first pulley, and the first pulley is movably connected to a second pulley via a first belt.

[0008] Preferably, the trimming mechanism includes a guide rail fixedly mounted on the processing frame, sliders slidably mounted at both ends of the guide rail, a fixed plate mounted on the sliders, a cutting machine and a limiting guide wheel mounted on the fixed plate, and a spring connected between the two fixed plates.

[0009] Preferably, the fixing plate has a waste hole.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the sheet metal trimming structure can limit the width of subsequent cuttings to be consistent with the width of the sheet metal between the two cut pieces by using limiting guide wheels on both sides. This ensures consistent cutting width, guarantees the precision of the cutting, avoids errors, and can adaptively adjust the distance between the two cutting machines according to the width of the sheet metal being cut, thus adapting to the cutting of sheet metal of different widths. Furthermore, the cut edge material can be pulled to the open space in front of the processing frame by the third bearing built-in traction roller, the collecting roller, and the first bearing built-in traction roller, facilitating the placement of the material collection device for collection.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Example: Figure 1-3As shown, an adaptive sheet metal trimming structure includes a processing frame 1. A collecting roller 2 is movably mounted on the front of the processing frame 1 via a bearing seat 5. U-shaped slots 31 are installed on both sides of the front of the processing frame 1. A first bearing-integrated traction roller 3 is fitted between the two U-shaped slots 31. A guide roller 4 is movably mounted on the top of the processing frame 1 via a bearing seat 5. A reduction motor 6 is installed below the processing frame 1. A trimming mechanism 7 is fixedly mounted on the processing frame 1 above the reduction motor 6. A second bearing-integrated traction roller 8 is installed on the inner side of the processing frame 1 below and behind the guide roller 4. A third bearing-integrated traction roller 9 is installed on the inner side of the processing frame 1 behind the trimming mechanism 7. The first bearing-integrated traction roller 3 is inserted into the U-shaped groove 31 by its own weight at both ends and comes into contact with the collecting roller 2. Specifically, the cut edge material passes through the waste hole, goes around the third bearing-integrated traction roller 9, and then passes between the collecting roller 2 and the first bearing-integrated traction roller 3. The collecting roller 2 and the first bearing-integrated traction roller 3 press the flexible plate edge material between them. At this time, the collecting roller 2 is driven by the guide roller 4 through the first belt 42, thereby pulling the edge material to the open position in front of the processing frame 1 for easy subsequent collection. The first bearing-integrated traction roller 3 is inserted into the U-shaped slot 31 by its own weight. Therefore, the first bearing-integrated traction roller 3 presses the edge material between the collecting roller 2 by its own weight, thereby generating a large friction force to achieve rolling traction.

[0015] The extended end of the geared motor 6 is equipped with a fourth pulley 61, and the two ends of the guide roller 4 are respectively connected to the third pulley 44 and the second pulley 41. The fourth pulley 61 is movably connected to the third pulley 44 through the second belt 43. Specifically, the geared motor 6 drives the fourth pulley 61 to rotate, and the fourth pulley 61 drives the third pulley 44 to rotate through the second belt 43, thereby driving the guide roller 4 to rotate and move the flexible sheet material. At this time, the sheet material passes between the guide roller 4 and the second bearing built-in traction roller 8 and is pulled.

[0016] One end of the collecting roller 2 is connected to a first pulley 21, and the first pulley 21 is movably connected to the second pulley 41 via a first belt 42; Specifically, the rotation of the guide roller 4 drives the second pulley 41 to rotate, which in turn drives the first pulley 21 to rotate via the first belt 42. The first pulley 21 then drives the collecting roller 2 to rotate. The edge strip passing between the collecting roller 2 and the first bearing-integrated traction roller 3 can be pulled to the front end of the processing frame 1 by this force for collection. During collection, the third bearing-integrated traction roller 9 mainly plays the role of guiding the edge strip.

[0017] The trimming mechanism 7 includes a guide rail 71 fixedly mounted on the processing frame 1, sliders 72 slidably mounted at both ends of the guide rail 71, a fixed plate 73 mounted on the sliders 72, a cutting machine 74 mounted on the fixed plate 73, a limiting guide wheel 75, and a spring 76 connected between the two fixed plates 73. Specifically, the slider 72 of the trimming mechanism 7 can slide on the guide rail 71, thereby adjusting the distance between the two cutting machines 74. This adapts to the cutting of flexible sheets of various widths. During cutting, the distance between the limit guide wheels 75 on both sides is the width of the sheet after processing and cutting. The cut sheet is clamped between these two distances. The clamping force is provided by the spring 76 connected between the sliders 72. This also ensures that the cutting position of the cutting machine 74 is accurate, and the cutting line of the cutting machine 74 is positioned according to the final required width.

[0018] The fixing plate 73 has a waste hole; Specifically, the waste hole is used for the passage of sheared edge strips, making them easy to collect.

[0019] It should be noted that this utility model is an adaptive sheet metal trimming structure. When using it, such as... Figure 3 As shown, the trimmed sheet material is clamped between the limiting guide rollers 75 on both sides by the tension of the spring 76. This structure is used to accurately control the cutting line of the cutting machine 74. The cut edge strip passes through the waste hole, goes around the third bearing built-in traction roller 9, and passes between the collecting roller 2 and the first bearing built-in traction roller 3. It is collected synchronously by the rotation of the collecting roller 2. The guide rail 71 and the slider 72 can adjust the position of the cutting machine 74 and the limiting guide rollers 75 on both sides, so that sheet materials of different widths can be cut. In addition, the sheet material cut by our company has a certain degree of flexibility and can be bent. However, during the cutting, the clamping force of the limiting guide rollers 75 on both sides by the spring 76 is insufficient to clamp and bend the cut sheet material, which affects the cutting accuracy. This is because the guide roller 4 of the sheet material and the second bearing built-in traction roller 8 can pull and flatten the sheet material. Similarly, the processed and cut sheet material is also placed between the same type of traction rollers to flatten and straighten it. Moreover, the sheet material is also very thick, so there is no situation of extrusion and bending as mentioned above.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
