Description
Technical Field
[0001] This utility model relates to the field of automotive parts bending machine technology, specifically to a bending machine for manufacturing automotive parts. Background Technology
[0002] Automotive parts are the various units that make up a car and the products that serve the car. However, the manufacturing of automotive parts requires the use of bending machines. In the manufacturing of automotive parts, bending machines are the core sheet metal processing equipment, which are specially used to precisely bend cold-rolled steel plates, aluminum alloys and other metal sheets into structural components such as frames, brackets, and reinforcing ribs required by the car, such as chassis brackets, door inner panels, bumper frames and so on.
[0003] Most sheet metal bending machines currently used typically consist of a bending die, a bending cutter, and a pressure cylinder. The sheet metal part to be bent is placed on the bending die, the pressure cylinder is activated, and the bending cutter presses onto the sheet metal part, entering the V-groove of the bending die, thus bending the sheet metal part to form the desired automotive component. However, in actual use, during the plastic deformation of the metal sheet, the contact surface between the sheet and the die generates strong friction. During this friction, fine metal powder, fine iron filings, aluminum filings, and oxide scale are scraped off and fall directly into the groove of the die. After prolonged processing, these impurities accumulate and will directly press indentations and scratches onto the surface of the component during bending, affecting the processing quality of the automotive component. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a bending machine for manufacturing automotive parts, which can effectively solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending machine for manufacturing automotive parts, comprising: a worktable, a bending die detachably mounted on the upper middle part of the worktable, a lifting plate above the bending die, a rack fixedly connected to one side of the lifting plate, the rack extending into the interior of the worktable, a protective box mounted on one side of the upper end of the worktable, a transmission rod rotatably connected to one side of the protective box, a transmission gear fixedly connected to one end of the transmission rod, the transmission gear meshing with the rack, a drive gear fixedly connected to the other end of the transmission rod, a mounting bracket fixedly connected to the bottom interior of the protective box, a driven gear rotatably connected to one side of the mounting bracket, the driven gear meshing with the drive gear, and a fan fixedly connected to one side of the driven gear via a connecting rod.
[0006] As a further preferred embodiment of this technical solution, the air outlet of the protective box is fixedly connected to a flow guide shroud, and the air outlet of the flow guide shroud is aligned with the V-shaped bending groove of the bending mold.
[0007] As a further preferred embodiment of this technical solution, a protective net is provided on one side of the air inlet of the protective box, and a mounting frame is slidably connected to the outer surface of the protective net, with one side of the mounting frame fixedly connected to one side of the protective box.
[0008] As a further preferred embodiment of this technical solution, an L-shaped bracket is fixedly connected to the other side of the upper end of the workbench, a bending cylinder is installed at the upper end of the L-shaped bracket, one end of the telescopic rod of the bending cylinder is fixedly connected to the upper end of the lifting plate, and a bending knife is installed at the lower end of the lifting plate.
[0009] As a further preferred embodiment of this technical solution, a guide rod is fixedly connected to one side of the L-shaped bracket, and one side of the guide rod is slidably connected to the inner wall of the rack.
[0010] As a further preferred embodiment of this technical solution, a cooling box is provided on one side of the bending mold, and a cleaning box is fixedly connected to one side of the cooling box. A filter screen is installed on the inner wall of the connection between the cooling box and the cleaning box, and a collection box is slidably connected to the inner wall of the cleaning box.
[0011] As a further preferred embodiment of this technical solution, a heat dissipation semiconductor is installed on one side of the cooling box, the cooling end of the heat dissipation semiconductor extends into the cooling box, a heat-conducting plate is fixedly connected to the cooling end of the heat dissipation semiconductor, and a flow guide plate is fixedly connected to the other side of the inner wall of the cooling box.
[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention utilizes a bending cylinder to raise the lifting plate, which in turn moves the rack. The rack meshes with the transmission gear, causing the drive gear to rotate. The drive gear meshes with the driven gear, causing the fan to rotate. The fan blows air from the protective box, which is then guided by a guide shroud to the V-groove of the bending die. This blows away impurities in the V-groove, preventing impurities generated during bending from remaining in the V-groove and affecting the quality of the bent parts. Furthermore, the blown air accelerates airflow on the surface of the bending die, cooling it and extending its service life.
[0013] 2. This utility model, through the structural design of multiple heat-conducting plates and multiple air-guiding plates, forms a labyrinthine channel inside the cooling box. When the fan blows air onto the bending die, the V-shaped groove guides the air into the cooling box, activating the heat dissipation semiconductor to cool the air entering the cooling box. At the same time, the labyrinthine channel increases the airflow time, preventing the air from quickly escaping from the cooling box's outlet, and simultaneously temperature-regulating the air. Thus, the air blown out of the cooling box's outlet cools the bending blade, improving its service life. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] The present invention will be further described below with reference to the embodiments.
[0019] This utility model provides a technical solution: such as Figure 1 - Figure 4As shown, in this embodiment, a bending machine for manufacturing automotive parts includes: a workbench 1, a bending die 14 detachably mounted on the upper middle part of the workbench 1, a lifting plate 12 above the bending die 14, a rack 31 fixedly connected to one side of the lifting plate 12, the rack 31 extending into the interior of the workbench 1, a protective box 3 mounted on one side of the upper end of the workbench 1, a transmission rod 36 rotatably connected to one side of the protective box 3, a transmission gear 32 fixedly connected to one end of the transmission rod 36, the transmission gear 32 meshing with the rack 31, a drive gear 33 fixedly connected to the other end of the transmission rod 36, a mounting bracket 37 fixedly connected to the bottom of the interior of the protective box 3, a driven gear 34 rotatably connected to one side of the mounting bracket 37, the driven gear 34 meshing with the drive gear 33, and a fan 35 fixedly connected to one side of the driven gear 34 via a connecting rod.
[0020] When the bending cylinder 11 is activated, the lifting plate 12 is raised, which drives the rack 31 to move. The rack 31 meshes with the transmission gear 32, causing the drive gear 33 to rotate. The drive gear 33 meshes with the driven gear 34, causing the fan 35 to rotate. The fan 35 blows the air inside the protective box 3, which is then guided by the guide shroud 51 and blown into the V-groove of the bending die 14. This blows away impurities in the V-groove, preventing impurities generated during bending from remaining in the V-groove of the bending die 14 and affecting the quality of the bent parts. In addition, the blown air accelerates the airflow on the surface of the bending die 14, cooling the bending die 14 and improving its service life.
[0021] It is important to note that because the size of the drive gear 33 is larger than that of the driven gear 34, the driven gear 34 rotates more times than the transmission gear 32, thus increasing the number of rotations of the fan 35 and ensuring that impurities on the bending die 14 are blown away. When the bending cylinder 11 raises the bending cutter 13, it first raises it to a certain distance and then stops. After the bent parts are removed, the bending cylinder 11 is restarted to raise the bending cutter 13 to the top.
[0022] like Figure 1 - Figure 3 As shown, the air outlet of the protective box 3 is fixedly connected to a guide shroud 51, and the air outlet of the guide shroud 51 is aligned with the V-shaped bending groove of the bending mold 14; the guide shroud 51 is conical, which concentrates the air blown out by the fan 35 and blows it out from the conical nozzle of the guide shroud 51, thereby increasing the airflow speed.
[0023] like Figure 1 and Figure 3As shown, a protective net 5 is provided on one side of the air inlet of the protective box 3. A mounting frame 52 is slidably connected to the outer surface of the protective net 5. One side of the mounting frame 52 is fixedly connected to one side of the protective box 3. The protective net 5 is used to filter impurities in the air entering the protective box 3, prevent dust in the air from getting between the drive gear 33 and the driven gear 34, and also prevent dust from being blown onto the bending mold 14.
[0024] like Figure 1 As shown, an L-shaped bracket 15 is fixedly connected to the other side of the upper end of the workbench 1. A bending cylinder 11 is installed on the upper end of the L-shaped bracket 15. One end of the telescopic rod of the bending cylinder 11 is fixedly connected to the upper end of the lifting plate 12. A bending knife 13 is installed on the lower end of the lifting plate 12. When the bending cylinder 11 is turned on, the lifting plate 12 and the bending knife 13 are moved. The bending knife 13 bends the sheet metal parts on the bending mold 14.
[0025] like Figure 1 and Figure 2 As shown, a guide rod 4 is fixedly connected to one side of the L-shaped bracket 15, and one side of the guide rod 4 is slidably connected to the inner wall of the rack 31; the guide rod 4 is used to limit the sliding direction of the rack 31 and prevent the rack 31 from being misaligned with the transmission gear 32.
[0026] like Figure 1 and Figure 4 As shown, a cooling box 2 is provided on one side of the bending die 14, and a cleaning box 24 is fixedly connected to one side of the cooling box 2. A filter screen 25 is installed on the inner wall of the connection between the cooling box 2 and the cleaning box 24, and a collection box 26 is slidably connected to the inner wall of the cleaning box 24. When the impurities and air in the V-groove of the bending die 14 are blown into the cleaning box 24 by the fan 35, the filter screen 25 filters the impurities, and the impurities fall into the collection box 26 for storage and collection.
[0027] like Figure 4 As shown, a heat dissipation semiconductor 21 is installed on one side of the cooling box 2. The cooling end of the heat dissipation semiconductor 21 extends into the cooling box 2. Multiple heat conduction plates 23 are fixedly connected to the cooling end of the heat dissipation semiconductor 21. Multiple flow guide plates 22 are fixedly connected to the other side of the inner wall of the cooling box 2. The multiple heat conduction plates 23 and multiple flow guide plates 22 interweave to form a labyrinthine channel.
[0028] Through the structural design of multiple heat-conducting plates 23 and multiple air-guiding plates 22, a labyrinthine channel is formed inside the cooling box 2. When the fan 35 blows air onto the bending die 14, the V-shaped groove guides the air into the cooling box 2, activating the heat dissipation semiconductor 21 to cool the air entering the cooling box 2. At the same time, the labyrinthine channel increases the airflow time, preventing the air from quickly escaping from the air outlet of the cooling box 2, and simultaneously temperature-regulating the air. Thus, the air blown out of the air outlet of the cooling box 2 cools the bending blade 13, improving the service life of the bending blade 13.
[0029] This utility model provides a bending machine for manufacturing automotive parts, and its specific working principle is as follows: When bending sheet metal parts to manufacture automotive components, the part to be bent is placed on the bending die 14, the bending cylinder 11 is activated, and the bending cutter 13 moves downward, pressing the sheet metal part into the V-groove of the bending die 14 to achieve bending. After bending, the bending cylinder 11 is activated again, raising the bending cutter 13 to a certain distance before stopping. After the bent part is removed, the bending cylinder 11 is activated again, raising the bending cutter 13 to the top. Simultaneously, the lifting plate 12 rises, driving the rack 31 to move. The rack 31 and the transmission gear 32 interact... When the drive gear 33 meshes with the driven gear 34, the fan 35 rotates, blowing air into the protective box 3. The air is then guided by the guide shroud 51 and blown into the V-groove of the bending die 14, removing impurities from the V-groove. At the same time, the V-groove guides the air into the cooling box 2, activating the heat dissipation semiconductor 21 to cool the air entering the cooling box 2. The labyrinthine channel increases the airflow time, preventing the air from quickly escaping from the air outlet of the cooling box 2, and simultaneously temperature-regulating the air. Thus, the air blown from the air outlet of the cooling box 2 cools the bending blade 13.
[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
