[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 3 , Figure 4 The present invention provides an embodiment of a flange expansion forming device, comprising a processing table 1, with a blowing and chip suction mechanism 2 and a translational clamping mechanism 3 disposed on the top of the processing table 1. The blowing and chip suction mechanism 2 includes a conical cylinder 211, which serves as the main structure of the entire blowing and chip suction section, providing space for internal airflow circulation and the installation of related components. The inner wall of the conical cylinder 211 has an air outlet chamber 212 and an air inlet chamber 213. The air outlet chamber 212 is used to guide the airflow blown out by the fan blades 217, and the top of the inner wall of the air inlet chamber 213 is connected to... The hole is connected to the air inlet chamber 213 to ensure smooth airflow within the chamber. A bidirectional motor 214 is fixedly connected to the inner wall of the air outlet chamber 212. The bidirectional motor 214 provides power to the rotating shaft 215, enabling it to drive the reamer 216 for reaming and to rotate the fan blades 217. The output end of the bidirectional motor 214 is fixedly connected to the rotating shaft 215, which transmits the power of the bidirectional motor 214 to the reamer 216 and the fan blades 217, ensuring the realization of the reaming and blowing / dust-collecting functions. A reamer 216 is fixedly connected to the bottom end. The reamer 216 acts directly on the flange, and performs reaming and forming of the flange through high-speed rotation. A fan blade 217 is fixedly connected to the top end of the rotating shaft 215. The fan blade 217 rotates under the drive of the rotating shaft 215, generating airflow to achieve the functions of blowing and sucking up chips. When it rotates, a negative pressure is generated at the top for sucking up chips, and airflow is blown out from the bottom for blowing up chips. A filter box 218 is fixedly connected to the outer wall of the conical cylinder 211. The filter box 218 filters the airflow containing small waste chips sucked in from the chip suction hood 221, separating them into... The filter box 218 is connected to the air inlet chamber 213 to separate the waste debris, so that the filtered airflow can enter the air inlet chamber 213 to maintain airflow circulation. The filter screen 219 is fixedly connected to the inner wall of the filter box 218. The filter screen 219 intercepts small waste debris in the airflow to achieve air-debris separation. The bottom of the filter box 218 is fixedly connected to the connecting pipe 220. The bottom end of the connecting pipe 220 is fixedly connected to the dust suction hood 221. The dust suction hood 221 uses the negative pressure generated by the rotation of the fan blades 217 to suck the smaller waste debris generated during the hole expansion process into the connecting pipe 220.
[0032] Reference Figure 1 , Figure 2The translation clamping mechanism 3 includes a support frame 311, the bottom of which is fixedly connected to the top of the processing table 1. The translation clamping mechanism 3 also includes a screw 312, which rotates under the drive of a servo motor 316. Through threaded engagement, the screw 312 drives the translation beam 314 to move, thereby adjusting the horizontal position of the reamer 216. One end of the screw 312 is rotatably connected to the inner wall of the support frame 311. The translation clamping mechanism 3 also includes a limiting rod 313, which limits the movement of the translation beam 314. The moving rod 313 acts as a limit, allowing it to move only along the axial direction of the screw 312. Both ends of the limit rod 313 are fixedly connected to the inner wall of the support frame 311. The translation clamping mechanism 3 also includes a translation beam 314, which is threadedly connected to the screw 312 and slidably sleeved on the limit rod 313. It can achieve horizontal translation under the rotation of the screw 312. One end of the translation beam 314 is threadedly connected to the outer wall of the screw 312, and the other end of the translation beam 314 is slidably sleeved on the outer wall of the limit rod 313.
[0033] Reference Figure 1 , Figure 2 The translation clamping mechanism 3 also includes a hydraulic rod 315. The hydraulic rod 315 pushes or pulls the conical cylinder 211 to adjust the position of the reamer 216 in the vertical direction. The bottom of the hydraulic rod 315 is fixedly connected to the top of the translation beam 314, and the bottom end of the inner rod of the hydraulic rod 315 is fixedly connected to the top of the conical cylinder 211. The translation clamping mechanism 3 also includes a servo motor 316, which provides power for the rotation of the screw 312. The outer wall of the servo motor 316 is fixedly connected to the right side of the support frame 311, and the output end of the servo motor 316 is fixedly connected to the other end of the screw 312. The translation clamping mechanism 3 also includes an electric push rod 317. After the electric push rod 317 is started, it drives the clamping block 318 to move, and clamps and fixes the flange placed on the processing table 1 through the clamping block 318. The outer wall of the electric push rod 317 is fixedly connected to the top of the processing table 1, and the clamping block 318 is fixedly connected to the inner rod of the electric push rod 317.
[0034] Working principle: When it is necessary to enlarge the flange, the flange to be enlarged is placed on the top of the processing table 1. By activating the electric actuator 317, the inner rod of the electric actuator 317 pushes the clamping block 318 to move, thereby clamping and fixing the flange to ensure that the flange position is stable during the enlargement process and will not be displaced or shaken due to external forces such as cutting forces, so as to facilitate subsequent enlargement. By activating the servo motor 316, the output end of the servo motor 316 drives the fixedly connected screw 312 to rotate. Under the limiting action of the limit rod 313, the translation beam 314 connected to the thread on the outer wall of the screw 312 is translated, thereby changing the position of the conical cylinder 211, and then driving the reaming drill 216 to move to the designated enlargement position, so as to facilitate subsequent enlargement shaping. By activating the hydraulic rod 315, the inner rod of the hydraulic rod 315 pushes the conical cylinder 211 to descend, thereby performing the enlargement work.
[0035] As the conical cylinder 211 descends, the bidirectional motor 214 is activated, causing its output to drive the fixedly connected rotating shaft 215 to rotate. This, in turn, drives the reamer 216, fixedly connected to the bottom of the rotating shaft 215, to rotate, thus reaming the flange. Simultaneously, the rotating shaft 215 rotates, causing the fan blades 217, fixedly connected to the outer wall of its top, to rotate. The rotating fan blades 217 blow air through the exhaust chamber 212 onto the flange, removing large pieces of debris generated during the reaming process. This prevents large pieces of waste from remaining on the flange and affecting the enlargement of the hole, and prevents waste from scratching the machined surface. When the fan blade 217 rotates, a negative pressure is generated at the top of the fan blade 217, which causes the dust suction hood 221 to suck up smaller waste. Then, it enters the filter box 218 through the connecting pipe 220. The filter screen 219 inside the filter box 218 can filter and intercept smaller waste. The airflow enters the air inlet chamber 213 and is finally blown out through the air outlet chamber 212, thus forming a closed airflow circulation system, which can reduce the dust content in the air in the workshop.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
