Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a blower tube forming device. Background Technology

[0002] Most existing automotive ventilation ducts are manufactured using blow molding or injection molding processes. Regardless of whether blow molding or injection molding is used, the scrap material at both ends of the automotive ventilation duct needs to be cut off to make it fit with other automotive parts. Automotive air conditioning duct cutting is done using an automotive air conditioning duct cutting device.

[0003] Currently, the removal of excess duct material is usually done manually, which results in poor product stability and low manual efficiency, affecting the cutting efficiency when cutting large quantities of ducts. Utility Model Content

[0004] The purpose of this invention is to provide a blower tube forming device, which aims to solve the technical problem that the efficiency of manual labor is relatively low in the existing technology, and that the cutting efficiency is affected when cutting a large number of blower tubes.

[0005] To achieve the above objectives, this utility model provides a blower tube forming device, including a workbench and a frame disposed on the workbench. The top surface of the workbench is provided with at least four workstations, and each workstation is provided with a plurality of positioning columns. Each positioning column includes an upper column and a lower column. A positioning clamping cavity is provided between the upper column and the lower column for clamping the blower tube. A positioning part is provided on one side of the positioning clamping cavity. A plurality of driving cylinders are provided at the bottom of the workbench. The output axis of the driving cylinder extends upward and is equipped with a cutter. A plurality of movable openings are provided on the workbench, which respectively cooperate with each of the cutters. A lifting cylinder is provided at the top of the frame. The output axis of the lifting cylinder extends downward and is equipped with a connecting plate. The bottom surface of the connecting plate is fixedly installed with each of the upper columns.

[0006] Preferably, the inner side of the frame is provided with several guide rails vertically, and the side of the connecting plate is slidably connected to each of the guide rails.

[0007] Preferably, the positioning part includes two guide grooves, which open toward the positioning clamping cavity and are aligned with the tangent of the blower pipe.

[0008] Preferably, the two sides of the cutter are slidably engaged with the two guide grooves respectively.

[0009] Preferably, the movable opening extends to one side and forms a discharge port that allows a portion of the blower tube to fall below the workbench.

[0010] Preferably, the upper column has grooves on both sides of the positioning clamping cavity, and the lower column has a toothed block at the top, with the grooves engaging with the toothed block.

[0011] Preferably, the top of the cutter has an equilateral triangle structure.

[0012] The blower tube forming device provided in this embodiment of the present invention has at least one of the following technical effects:

[0013] In operation, the connecting plate is lifted by a lifting cylinder, which in turn lifts each upper column upwards, opening the positioning clamping cavity. The semi-finished air tubes are then placed in their respective workstations, ensuring that all cuts on the air tubes are aligned with the positioning clamping cavities of the lower columns. The positioning mechanism confirms the alignment of the tangent with the movable opening and the cutter, achieving precise positioning and preventing displacement of the air tubes during cutting. The connecting plate is then lowered by the lifting cylinder, causing each upper column to move downwards, closing the positioning clamping cavity and holding the air tubes. Simultaneously, the cutter is driven upwards by various drive cylinders, cutting along the tangent of the air tubes to remove waste material from the ends, achieving precise cutting. The connecting plate allows for simultaneous opening of the positioning clamping cavities at each workstation, enabling the simultaneous installation of multiple semi-finished air tubes into their respective positioning clamping cavities.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0022] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] In one embodiment of this utility model, such as Figures 1-5As shown, a blower tube forming device is provided, including a workbench 1 and a frame 2 disposed on the workbench 1. The top surface of the workbench 1 is provided with at least four workstations 3. Each workstation 3 is provided with a plurality of positioning columns 31. Each positioning column 31 includes an upper column 311 and a lower column 312. A positioning clamping cavity 313 is provided between the upper column 311 and the lower column 312 for clamping the blower tube 10. A positioning part is provided on one side of the positioning clamping cavity 313. A plurality of driving cylinders 11 are provided at the bottom of the workbench 1. The output axis of the driving cylinder 11 extends upward and is equipped with a cutter 32. A plurality of movable openings are provided on the workbench 1, which respectively cooperate with each of the cutters 32. A lifting cylinder 21 is provided at the top of the frame 2. The output axis of the lifting cylinder 21 extends downward and is equipped with a connecting plate 22. The bottom surface of the connecting plate 22 is fixedly installed with each of the upper columns 311.

[0026] Furthermore, the inner side of the frame 2 is vertically provided with several guide rails 23, and the side of the connecting plate 22 is slidably connected to each of the guide rails 23. Specifically, during the up-and-down movement of the connecting plate 22, power is provided by the lifting cylinder 21, and the side of the connecting plate 22 slides in cooperation with each guide rail 23, making the up-and-down sliding of the connecting plate 22 more vertical and linear. After each semi-finished air pipe 10 is installed in each positioning clamping cavity 313, the lifting cylinder 21 drives the connecting plate 22 to move downward, so that when the upper column 311 falls on the top surface of the lower column 312, the positioning clamping cavity 313 can better fix the semi-finished air pipe 10, avoid the semi-finished air pipe 10 from changing position during operation, and improve product quality.

[0027] Furthermore, the positioning part includes two guide grooves 33, which open towards the positioning clamping cavity 313 and are aligned with the tangent of the blower tube 10. The cutter 32 slides within the two guide grooves 33 on both sides. Specifically, when the semi-finished blower tube 10 is installed in the positioning clamping cavity 313, the positioning effect can be achieved by observing whether the tangent of the semi-finished blower tube 10 is aligned with the opening direction of the guide groove 33. When the tangent is aligned with the opening direction of the guide groove 33, the position is correct. Then, the upper column 311 is lowered to clamp the semi-finished blower tube 10 on its top surface to achieve a fixing effect. During cutting, the cutter 32 is driven upward by the drive cylinder 11 and slides with the guide groove 33 to cut the semi-finished blower tube 10, achieving a precise cutting effect.

[0028] Furthermore, the movable opening extends to one side and forms a shape that allows a portion of the blower pipe 10 to fall into the discharge port 12 of the workbench 1. Specifically, the connecting plate 22 is raised by the lifting cylinder 21, which in turn raises the upper column 311, opening the positioning clamping cavity 313 between the upper column 311 and the lower column 312. The operator then installs the semi-finished air pipe 10 into the positioning clamping cavity 313 of the lower column 312. The positioning part confirms that the position of the tangent line corresponds to the movable opening and the cutter 32. The connecting plate 22 is then lowered by the lifting cylinder 21, which drives each upper column 311 to move downward, closing the positioning clamping cavity 313 and clamping the semi-finished air pipe 10. Simultaneously, each drive cylinder 11 drives the cutter 32 to move upward and cut along the tangent line of the semi-finished air pipe 10, removing the waste material 101 at the end of the semi-finished air pipe 10. The removed waste material 101 falls downward through the opening to the bottom of the workbench 1, preventing the waste material 101 from accumulating on the workbench 1 and affecting subsequent production.

[0029] Furthermore, the upper column 311 is provided with grooves 34 on both sides of the positioning clamping cavity 313, and the lower column 312 is provided with toothed blocks 35 at the top, with the grooves 34 and the toothed blocks 35 engaging. Specifically, in use, the connecting plate 22 is lifted by the lifting cylinder 21, causing the grooves 34 of the upper column 311 to separate from the toothed blocks 35 of the lower column 312, thus opening the positioning clamping cavity 313. When the lifting cylinder 21 lowers the connecting plate 22, the grooves 34 of the upper column 311 and the toothed blocks 35 of the lower column 312 engage, keeping the relative positions of the upper column 311 and the lower column 312 fixed, preventing displacement of the upper column 311 and the lower column 312 when subjected to external forces, and preventing deformation of the semi-finished blower tube 10 in the positioning clamping cavity 313, thereby improving the product yield.

[0030] Furthermore, the top of the cutter 32 has an equilateral triangle structure. Specifically, when the cutter 32 removes the waste 101 from the semi-finished blower tube 10, the equilateral triangle structure at the top of the cutter 32 will first pierce the middle of the bottom surface of the tangent line, maintaining the force balance on both sides of the semi-finished blower tube 10, and gradually cutting through the two hypotenuses of the equilateral triangle structure to maintain the force balance on both sides of the semi-finished blower tube 10 during the cutting process, thus avoiding deformation of the semi-finished blower tube 10 during the cutting process and affecting the cutting effect.

[0031] Working principle: During use, the connecting plate 22 is lifted by the lifting cylinder 21, which in turn lifts each upper column 311 upwards, opening the positioning clamping cavity 313. The semi-finished air pipe 10 is placed in each workstation 3, ensuring that each cut on the semi-finished air pipe 10 is installed in the positioning clamping cavity 313 of the lower column 312. The positioning part confirms that the tangent position corresponds to the movable opening and the cutter 32, achieving a precise positioning effect and preventing displacement of the semi-finished air pipe 10 during the cutting process. The connecting plate 22 is lowered by the lifting cylinder 21, which in turn moves each upper column 311 downwards, closing the positioning clamping cavity 313 to hold the semi-finished air pipe 10. The cutter 32 is simultaneously driven upwards by each drive cylinder 11 and cuts along the tangent of the semi-finished air pipe 10, removing the waste material 101 at the end of the semi-finished air pipe 10 and achieving a precise cutting effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
