It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated mechanism or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention.

[0034] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific situations.

[0035] As Figure 1 、 Figure 2 shown, a conical barrel flanging machine includes a frame 1. A first working station 2 and a second working station 3 are fixedly arranged on the frame 1. The first working station 2 is used for processing the large mouth of the conical barrel, and the second working station 3 is used for processing the small mouth of the conical barrel. The first working station 2 and the second working station 3 form a certain angle as a whole, which can save space and is convenient for operation at the same time. The surface of the frame 1 where the first working station 2 is located is provided with an inscribed trapezoidal notch, which is convenient for workers to operate at a closer distance.

[0036] As Figure 2-4As shown in the figure, the first working station 2 includes a first processing platform 201 and a first flanging mechanism 202. The first processing platform 201 is horizontally provided with a first support frame 2011, a pressure plate 2012 and a fixed plate 2014. The upper surface of the fixed plate 2014 is provided with a first workpiece processing station 2015. The large-mouth flanging of the conical cylinder is completed at the first workpiece processing station 2015. The center of the top of the pressure plate 2012 is provided with a lead screw which passes through the top of the first support frame 2011 and is connected to a first hydraulic cylinder 2013. The expansion and contraction of the first hydraulic cylinder 2013 can drive the lifting of the pressure plate 2012, so that the pressure plate 2012 contacts the conical cylinder at the first workpiece processing station 2015, and the clamping and positioning of the workpiece are completed. The center of the bottom of the fixed plate 2014 is connected to a rotating shaft 2016. The first motor 203 is placed below the horizontal tabletop of the frame 1. The rotating shaft 2016 passes through the plane of the frame 1 and is connected to the first motor 203. The fixed plate 2014 rotates under the drive of the first motor 203, driving the workpiece at the first workpiece processing station 2015 to rotate, so as to complete the flanging operation.

[0037] The first flanging mechanism 202 includes a first moving support 2021. The first moving support 2021 is further provided with a first pressing wheel 2022 which is matched with the position of the fixed plate 2014. The first pressing wheel 2022 is connected to the first moving support 2021 through a support plate. The top of the first moving support 2021 is provided with a second hydraulic cylinder 2025. The output end of the second hydraulic cylinder 2025 passes through the top of the first moving support 2021 and is fixedly connected to the support plate through a connecting block. The expansion and contraction of the second hydraulic cylinder 2025 can drive the support plate to move up and down, thereby driving the first pressing wheel 2022 fixedly connected to the surface of the support plate to move up and down and adjusting to a suitable height. The surface of the frame 1 is provided with a first moving guide rail 2023. The bottom of the first moving support 2021 is provided with a lead screw 2024. The rotation of the lead screw 2024 driven by an external power source (not shown in the figure) drives the first moving support 2021 to move along the first moving guide rail 2023, so that the first pressing wheel 2022 contacts the large mouth of the conical cylinder at the first workpiece processing station 2015, and then the large mouth of the conical cylinder at the first workpiece processing station 2015 is flanged.

[0038] As Figure 5-8As shown, the second working station 3 includes a second processing platform 301 and a second flanging mechanism 302. The second processing platform 301 includes a second support frame 3011, a fixing frame 3012, and a rotating disk 3015. Between the upper and lower disks of the fixing frame 3012, there is a second workpiece to be processed position 3014. The small end flanging of the conical cylinder is completed at the second workpiece to be processed position 3014. At the center of the top of the fixing frame 3012, there is a lead screw that passes through the top of the second support frame 3011 and is connected to a third hydraulic cylinder 3013. The expansion and contraction of the third hydraulic cylinder 3013 can drive the lifting of the fixing frame 3012, so that the fixing frame 3012 contacts the lower part of the conical cylinder at the second workpiece to be processed position 3014, completing the fixation of the workpiece to be processed. The rotating shaft at the center of the bottom of the rotating disk 3015 passes through the plane of the frame 1 and is coaxially connected to a second motor 303. The second motor 303 is arranged below the horizontal tabletop of the frame 1. The rotating disk 3015 rotates driven by the second motor 303, driving the workpiece at the second workpiece to be processed position 3014 to rotate, so as to complete the flanging operation.

[0039] The second flanging mechanism 302 includes a second moving support 3021. The second flanging mechanism 302 is provided with an inclined second pressing wheel 3022 and a horizontal top wheel 3023. There is a gap between the lower end surface of the second pressing wheel 3022 and the edge of the top wheel 3023. The second pressing wheel 3022 is connected to the second moving support 3021 through a support frame. At the top of the second moving support 3021, there is a fourth hydraulic cylinder 3024. The output end of the fourth hydraulic cylinder 3024 passes through the top of the second moving support 3021 and is fixedly connected to the support frame through a connecting block. Thus, through the expansion and contraction of the output end of the fourth hydraulic cylinder 3024, the support frame can be driven to move up and down, driving the second pressing wheel 3022 to move up and down, so that the second pressing wheel 3022 can be adjusted to a suitable position.

[0040] The upper and lower surfaces of the top wheel 3023 are fixed through an installation mechanism. On the side of the second moving support 3021, there is a vertically arranged installation frame. Behind the installation frame, there is a fifth hydraulic cylinder 3025. The output end of the fifth hydraulic cylinder 3025 passes through the installation frame and is fixedly connected to the installation mechanism. Thus, through the expansion and contraction of the output end of the fifth hydraulic cylinder 3025, the installation mechanism can be driven to move back and forth, driving the top wheel 3023 to move back and forth, so that the top wheel 3023 can be adjusted to a suitable position.

[0041] The surface of the frame 1 is provided with a second moving guide rail 3026. The bottom of the second moving support 3021 is placed on the surface of the second moving guide rail 3026. One side of the second moving support 3021 away from the second processing platform 301 is connected with a sixth hydraulic cylinder 3027. The output end of the sixth hydraulic cylinder 3027 is fixedly connected to the second moving support 3021. Thus, through the telescopic movement of the output end of the sixth hydraulic cylinder 3027, the second moving support 3021 can be driven to move forward or backward on the surface of the second moving guide rail 3026, so as to adjust the overall position of the second moving support 3021, enabling the second pressing wheel 3022 and the top wheel 3023 to reach the second workpiece to be processed station 3014.

[0042] As Figure 6 , Figure 7 shown, the bottom of the second pressing wheel 3022 is placed inside the workpiece to be processed, and the top wheel 3023 is placed outside the workpiece to be processed. The two cooperate with each other to complete the flanging operation of the small opening of the conical cylinder.

[0043] Both the first station 2 and the second station 3 are provided with multiple position detection and induction devices integrating photoelectric induction, magnetic switches, etc. (not shown in the figure). For example, at the bottom of the pressure plate 2012, between the first pressing wheel 2022 and the workpiece to be processed, between the first pressing wheel 2022, the top wheel 3023 and the workpiece to be processed, and between the fixed frame 3012 and the workpiece to be processed, induction devices are provided to accurately locate the positions of the movable devices in the equipment; each hydraulic cylinder and motor is controlled by a PLC to enable fast and accurate processing and realize automated production.

[0044] At the first workpiece to be processed station 2015 and the second workpiece to be processed station 3014, a projection photoelectric grating (not shown in the figure) is provided. When the operator places and removes the workpiece, the grating is blocked and the entire equipment cannot be started to ensure the safety of the operator.

[0045] When the utility model is in use, all components of the equipment are in the initial position of being separated from each other. The operator places the conical cylinder to be processed on the first workpiece processing station 2015. The large-mouth end of the conical cylinder is placed on the upper surface of the fixed disk 2014. The equipment is started, and the first hydraulic cylinder 2013 drives the pressure plate 2012 to descend to complete the clamping and positioning of the workpiece. The positioning is completed with the cooperation of the induction device. The external power drives the lead screw 2024 to rotate, driving the first moving support 2021 to move on the surface of the first moving guide rail 2023, so that the first pressing wheel 2022 on the first moving support 2021 reaches the first workpiece processing station 2015. Then, the height of the first pressing wheel 2022 is adjusted by the second hydraulic cylinder 2025, so that the first pressing wheel 2022 contacts the edge of the large mouth of the conical cylinder. The positioning is completed with the cooperation of the induction device. The first motor 203 drives the fixed disk 2014 to rotate, driving the conical cylinder to rotate to complete the flanging processing of the large mouth. Reset all components of the first station 2, remove the workpiece that has completed the flanging processing of the large mouth, and place it on the second workpiece processing station 3014 of the second station 3. Without turning it over, the large-mouth end of the conical cylinder is still located below. The third hydraulic cylinder 3013 drives the fixed frame 3012 to descend until it contacts the outer wall of the conical cylinder to be processed to complete the clamping and positioning. The positioning is completed with the cooperation of the induction device. The sixth hydraulic cylinder 3027 drives the second moving support 3021 to move on the surface of the second moving guide rail 3026, so that the second pressing wheel 3022 and the top wheel 3023 on the second moving support 3021 reach the second workpiece processing station 3014. Then, the height of the second pressing wheel 3022 is adjusted by the fourth hydraulic cylinder 3024, so that the second pressing wheel 3022 contacts the inner side of the edge of the small mouth of the conical cylinder. Then, the top wheel 3023 is adjusted to move forward by the fifth hydraulic cylinder 3025 and contacts the outer side of the edge of the small mouth of the conical cylinder. The positioning is completed with the cooperation of the induction device. The second motor 303 drives the rotating disk 3015 to rotate, driving the conical cylinder to rotate to complete the flanging processing of the small mouth. The entire positioning and rotation operations are controlled by the PLC, and the flanging processing can be carried out quickly and accurately. In cooperation with the projection photoelectric grid, when it is blocked, the equipment pauses to ensure the safety of the operators for loading and unloading workpieces.

[0046] The above has described the present utility model in detail through embodiments, but the above content is only the preferred embodiment of the present utility model and cannot be considered as limiting the implementation scope of the present utility model. Any equal changes and improvements made according to the scope of the application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
