Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, and in particular to an extrusion device for producing metal pipe fittings. Background Technology

[0002] Extrusion equipment for metal pipe fitting production is a specialized device that uses external force to extrude metal billets (such as aluminum, copper, steel, titanium alloys, etc.) into tubular parts. It is widely used in the automotive, aerospace, petrochemical, and pipeline engineering industries. Its core principle is to use the combined action of a die and external force to cause plastic deformation of the metal billet, ultimately forming pipe fittings that meet dimensional accuracy and mechanical performance requirements.

[0003] By comparing a pipe extrusion molding device with patent publication number CN222970704U, in this solution, the hydraulic telescopic rod can drive the upper mold to move downward, thereby driving the first shaping plate to move downward. In cooperation with the second shaping plate, it can extrude the material in the lower mold. However, after multiple extrusion moldings of the pipe, the lower mold may become misaligned due to the repeated extrusion of the upper mold, lower mold and pipe. This may cause a deviation in the concentricity of the pipe during extrusion, resulting in slight deformation of the extruded pipe, which may reduce the quality of pipe production.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0028] In this embodiment: the longitudinal pressing mechanism includes a bottom frame 201 disposed on the upper end of the base plate 100, a lifting plate 203 slidably installed inside the bottom frame 201, a lifting hydraulic cylinder 202 disposed between the lifting plate 203 and the bottom frame 201, a lower mold 204 disposed on the upper end of the lifting plate 203, a support frame 217 disposed on the rear side of the base plate 100, a pressing hydraulic cylinder 218 disposed on the upper end of the support frame 217, a pressing plate 219 disposed on the lower end of the pressing hydraulic cylinder 218, an upper mold 220 disposed on the lower end of the pressing plate 219, and positioning structures for concentric positioning of the lower mold 204 and the upper mold 220 are provided on both sides of the upper mold 220 and the lower mold 204.

[0029] The positioning structure includes rotating plates 205 rotatably mounted on both sides of the base frame 201. A rotating motor 206 is installed at the rotating end of the rotating plate 205. The output end of the rotating motor 206 is fixed to the rotating end of the rotating plate 205 through a coupling. A positioning disc 207 is installed at the upper end of the rotating plate 205. A pushing hydraulic cylinder 208 is provided between the positioning disc 207 and the rotating plate 205. Slide grooves are opened on both the upper and lower sides of the positioning disc 207. Positioning plates 209 are slidably installed inside the slide grooves. A compression spring is connected between the positioning plates 209 and the inner wall of the slide groove. The end of the positioning plate 209 is arc-shaped. A button 210 is installed at the end of the inner wall of the slide groove near the center of the positioning disc 207. A cleaning structure is provided at the center of the positioning disc 207 for cleaning residual waste on the surface of the upper mold 220 and the lower mold 204.

[0030] The cleaning structure includes a rotating shaft 221 rotatably positioned at the center of the positioning plate 207. A rotary motor 212 is installed at the rotating end of the rotating shaft 221. The output end of the rotary motor 212 is fixed to the rotating end of the rotating shaft 221 via a coupling. A blower 211 is installed at the end of the rotating shaft 221 away from the lower mold 204. A protective cover 213 is provided on the surface of the positioning plate 207 near the blower 211. Multiple air outlets are provided on the surface of the protective cover 213. A vibration structure is provided on the surface of the positioning plate 207 to drive the lower mold 204 and the upper mold 220 to vibrate.

[0031] The vibration structure includes a rotating frame 214 fixedly mounted on one end of the rotating shaft 221 near the lower mold 204. A striking plate 216 is slidably installed inside the rotating frame 214. A storage spring connects the striking plate 216 and the rotating frame 214. Multiple arc-shaped blocks 215 are mounted around the edge of the positioning plate 207. The side of the arc-shaped block 215 near the striking plate 216 is inclined, and the side away from the striking plate 216 is flat. The end of the striking plate 216 is made of rubber. The metal pipe is extruded and formed by the cooperation of the horizontal pressing mechanism and the vertical pressing mechanism. Before each extrusion of the pipe, the positioning structure is used to adjust the axis of the lower mold 204 and the upper mold 220 to be on the same horizontal line as the axis of the horizontal pressing mechanism. The positions of the lower mold 204 and the upper mold 220 are positioned to prevent slight deformation of the extruded pipe, thereby ensuring the concentricity of the pipe and improving the quality of pipe production.

[0032] In this embodiment: the horizontal pressing mechanism includes slide rails 301 arranged on the front and rear sides of the base plate 100. A lead screw 302 is rotatably installed in the slide rails 301. A moving motor 303 is installed at the rotating end of the lead screw 302. The output end of the moving motor 303 is fixed to the rotating end of the lead screw 302 through a coupling. Two movable frames 304 are slidably installed between the two slide rails 301 in a symmetrical arrangement along the front and rear direction. The movable frames 304 are threadedly connected to the lead screw 302. The threads at both ends of the lead screw 302 are in opposite directions. A pushing column 305 is installed on the upper side wall of the movable frame 304. The pushing column 305 is bolted to the movable frame 304. The pushing column 305 is coaxial with the positioning plate 207.

[0033] Working principle: First, the lower hydraulic cylinder 218 is activated, driving the lower pressure plate 219 to move downwards, which in turn moves the upper mold 220 downwards, so that the upper mold 220 moves directly above the lower mold 204. Then, the rotating motor 206 is activated, driving the rotating plate 205 to flip upwards to the end of the lower mold 204. Then, the pushing hydraulic cylinder 208 is driven to drive the positioning plate 207 to extend between the lower mold 204 and the upper mold 220, moving the positioning plate 207 towards the center of the lower mold 204. Then, the inner walls of the lower mold 204 and the upper mold 220 will press against the positioning plates 209 at the upper and lower ends of the positioning plate 207, causing the positioning plates 209 to retract into the groove. When the positioning plate 209 touches the button 210, it indicates that the lower mold 204 is in operation. If the position of mold 204 is accurate, there is no need to adjust the height of the lower mold 204. If the positioning plate 209 does not touch the button 210, the lifting hydraulic cylinder 202 is driven to push the lifting plate 203 upward, which in turn pushes the lower mold 204 upward. At this time, the lower mold 204 will push the positioning plate 209 upward until the positioning plate 209 touches the button 210 and stops the lower mold 204 from rising. At this time, the lower mold 204 is in the correct processing position. Positioning the lower mold 204 and adjusting the position of the upper mold 220 are the same as the above adjustment principle to prevent slight deformation of the extruded pipe, thereby ensuring the concentricity of the pipe and improving the quality of pipe production.

[0034] At this time, the rotary motor 212 is started, driving the rotating shaft 221 to rotate. The rotating shaft 221 drives the rotating frame 214 to rotate, which in turn drives the striking plate 216 to rotate. When the striking plate 216 rotates, it will press against multiple arc-shaped blocks 215 on the surface of the positioning disk 207. The arc-shaped blocks 215 will gradually press the striking plate 216 into the rotating frame 214 to store force. When the striking plate 216 is released from the pressure of the arc-shaped blocks 215, the striking plate 216 releases its stored force. When the spring is released, it will quickly extend outward to strike the inner walls of the lower mold 204 and the upper mold 220, causing the upper mold 220 and the lower mold 204 to vibrate and shake off any residual waste on the inner walls of the upper mold 220 and the lower mold 204. Then, when the rotating shaft 221 rotates again, it drives the blower 211 to rotate. The blower 211 blows the waste between the upper mold 220 and the lower mold 204 outward to prevent the waste from affecting the next extrusion of the pipe fitting.

[0035] Then, the rotating motor 206 drives the rotating plate 205 to rotate downwards, moving the positioning plate 207 below the bottom frame 201. The pipe to be processed is then placed on the lower mold 204, and the downward hydraulic cylinder 218 is driven to move the upper mold 220 downwards. The upper mold 220 and the lower mold 204 cooperate to longitudinally extrude the pipe. At the same time, the moving motor 303 is started to drive the lead screw 302 to rotate, causing the moving frames 304 on both sides to move towards each other, and causing the two pushing columns 305 to move towards each other. The two pushing columns 305 are moved simultaneously to the space between the upper mold 220 and the lower mold 204. The two pushing columns 305 apply lateral extrusion force to the pipe, and the pipe is extruded and shaped by the cooperation of the two, thus completing the production of the pipe.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
