[0001] This utility model relates to the field of extrusion press technology, and in particular to a push-pull nozzle mechanism for an extrusion press and an extrusion press. Background Technology

[0002] During the extrusion process of aluminum profile extrusion presses, the extrusion pad comes into direct contact with the aluminum rod, which can easily cause aluminum to stick, affecting the normal operation of the equipment and the quality of the extruded products. Usually, a release agent needs to be sprayed onto the extrusion pad. The release agent has the characteristics of being easy to cure at high temperatures, and can form a protective film during the extrusion process to prevent the aluminum rod from directly contacting the extrusion pad and sticking with aluminum. Currently, most aluminum factories spray this manually, which requires machine shutdown and affects production efficiency. In addition, since the extrusion pad is usually placed in a high-temperature area, manual spraying can easily cause burns, posing a safety hazard. Utility Model Content

[0006] Furthermore, the nozzle mechanism also includes a drive rod, one end of which is connected to the drive member, and the other end of which is connected to the nozzle. The drive member is used to drive the drive rod to move closer to or away from the extrusion pad.

[0021] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] Example 1,

[0025] See Figures 1 to 3 This utility model discloses a push-pull nozzle mechanism 20 for an extruder, including: an extrusion pad 11, a mounting frame, and a nozzle mechanism 20. The mounting frame is set on the side close to the extrusion pad 11, and the nozzle mechanism 20 is mounted on the mounting frame. The nozzle mechanism 20 includes a drive member 21 and a nozzle 23. The nozzle 23 can move closer to or away from the extrusion pad 11. The drive member 21 is connected to the nozzle 23 and is used to drive the nozzle 23 to move closer to or away from the extrusion pad 11, and sprays the extrusion pad 11 when it moves closer to the extrusion pad 11.

[0026] Based on the above structure, during assembly, the mounting bracket is installed on the side of the extruder close to the extrusion pad 11, the drive component 21 is installed on the mounting bracket, and the nozzle 23 is connected to the drive component 21. The spray port 234 of the nozzle 23 is set towards the extrusion pad 11 so that the nozzle 23 is driven to move closer to or away from the extrusion pad 11 by the drive component 21.

[0027] In practical use, the release agent is introduced into the nozzle 23 through the hose. When it is necessary to spray the extrusion pad 11, the drive unit 21 is activated to drive the nozzle 23 to move closer to the extrusion pad 11. At this time, the nozzle 23 sprays the release agent onto the extrusion pad 11. After the spraying operation is completed, the drive unit 21 drives the nozzle 23 away from the extrusion pad 11 again to reset the nozzle 23.

[0028] Currently, when aluminum profile extrusion presses need to spray release agent onto the extrusion pad 11 during extrusion operations, most of the time the machine needs to be stopped and the spraying is done manually, which affects production efficiency. In addition, since the extrusion pad 11 is usually located in a high-temperature area, manual spraying can easily cause burns, posing a safety hazard.

[0029] Therefore, when the push-pull nozzle mechanism 20 of the extruder in this embodiment is applied to the extruder equipment, during assembly, the mounting bracket is installed on the outer periphery of the extruder and set on the side close to the extrusion pad 11. When it is necessary to spray the extrusion pad 11, it is only necessary to start the drive component 21 to drive the nozzle 23 to move close to the extrusion pad 11, and then spray the release agent onto the extrusion pad 11 through the nozzle 23. There is no need to stop the machine or manually spray during the spraying process, realizing automatic spraying of the release agent, improving production efficiency, and making the operation safer.

[0030] After the release agent is sprayed, the drive unit 21 is activated again to drive the nozzle 23 away from the extrusion pad 11. That is, the nozzle 23 is driven away from the high temperature zone to avoid the nozzle deformation caused by high temperature, improve the service life of the nozzle 23, and prevent the release agent solution from solidifying in the nozzle 23 and causing blockage. The structure is more practical.

[0031] More specifically, the driving component 21 can be an existing driving cylinder or driving motor. When the driving component 21 is a driving cylinder, during assembly, the nozzle 23 can be connected to the piston rod of the driving cylinder through a connecting shaft or connecting rod. When the cylinder body drives the piston rod to move back and forth, it can drive the nozzle 23 to move linearly to move closer to or away from the extrusion pad 11. Of course, the nozzle 23 can also be directly connected to the piston rod of the driving cylinder, depending on the actual scenario.

[0032] Alternatively, when an existing drive motor is selected for the drive component 21, a suitable transmission mechanism, such as a lead screw or a timing belt, can be used to convert the rotational motion of the motor into the linear motion of the nozzle 23. Taking a lead screw as an example, the rotational motion of the drive motor is converted into reciprocating linear motion through the cooperation of the lead screw and the lead screw nut. During assembly, the motor shaft of the drive motor is connected to the lead screw to drive the lead screw to rotate. Then, the nozzle 23 is connected to the lead screw nut that passes through the lead screw. Thus, when the lead screw rotates and drives the lead screw nut to make linear motion, it can drive the nozzle 23 to make linear motion. Alternatively, the transmission can be achieved through the non-slip meshing motion of the timing belt and the timing pulley, which can also convert the rotational motion of the drive motor into linear motion to drive the nozzle 23 to make linear motion.

[0033] Furthermore, the nozzle mechanism 20 also includes a drive rod 22. During assembly, one end of the drive rod 22 is connected to the drive member 21, and the other end of the drive rod 22 is connected to the nozzle 23, so that the drive member 21 drives the drive rod 22 to move closer to or away from the extrusion pad 11, thereby causing the nozzle 23 connected to the drive rod 22 to move closer to or away from the extrusion pad 11.

[0034] Specifically, in this embodiment, the drive rod 22 is used as an intermediate connector to connect the nozzle 23. When the nozzle 23 needs to be maintained or replaced, the nozzle 23 can be maintained, replaced or adjusted separately without disassembling the entire nozzle mechanism 20, which improves the maintainability of the entire structure and reduces maintenance costs and time.

[0035] In addition, the drive rod 22 can be made of high-temperature resistant materials, or the drive rod 22 can be wrapped with heat insulation cotton or heat insulation sleeve, so that the drive rod 22 can maintain sufficient strength and stability in high-temperature environment, thereby extending the service life of the nozzle mechanism 20.

[0036] Preferably, in this embodiment, the driving component 21 is a driving cylinder. In this case, the piston rod of the driving cylinder is formed as a driving rod 22. When the driving cylinder drives the piston rod to reciprocate linearly, it can directly drive the nozzle 23 to reciprocate linearly without the need for an extra transmission mechanism, making the assembly structure simpler.

[0037] Furthermore, in this embodiment, the driving cylinder is a dual-axis cylinder. Compared with ordinary driving cylinders, dual-axis cylinders have a faster operating speed. This is due to the rapid compression and release of gas. The rapid action execution capability can significantly improve the production efficiency of the equipment, allowing the nozzle 23 to move closer to the extrusion pad 11 more quickly, so as to quickly spray the release agent onto the extrusion pad 11 and quickly move away from the high temperature zone where the extrusion pad 11 is located, avoiding high temperature damage to the nozzle 23 and indirectly improving the service life of the nozzle 23.

[0038] In addition, dual-axis cylinders are typically equipped with two guide shafts, and the piston rod and link are combined into a floating shaft plate. This design allows the cylinder to maintain high precision when subjected to lateral forces, thereby improving the guiding accuracy and stability of the cylinder and making the nozzle mechanism 20 more stable.

[0039] Furthermore, the outer periphery of the drive rod 22 is provided with heat insulation pads, such as those made of calcium silicate or ceramic fiber, which have high temperature resistance and low thermal conductivity. During assembly, the heat insulation pads are wrapped around the outer periphery of the drive rod 22 to insulate against heat and prevent the drive rod 22 from being damaged by high temperature when it extends into the high temperature zone, thereby improving the service life of the structure.

[0040] Furthermore, since the mounting bracket is located near the compression pad 11, in order to prevent the mounting bracket from being damaged by the residual heat of the high temperature, the outer periphery of the mounting bracket in this embodiment is provided with a heat insulation sleeve. The heat insulation sleeve is used for heat insulation, reducing the risk of the mounting bracket being damaged by high temperature and improving the service life of the structure.

[0041] Preferably, the heat insulation sleeve can be made of materials such as ceramic fiber or polyurethane that are resistant to high temperatures and have low thermal conductivity.

[0042] More specifically, the nozzle 23 is made of high-temperature resistant materials, such as stainless steel or titanium alloy, to reduce the impact of high temperatures on the nozzle 23 and prevent deformation, thereby improving the service life of the nozzle 23.

[0043] Furthermore, the nozzle 23 includes a first interface 231, a second interface 232, a third interface 233, and a spray port 234. The first interface 231, the second interface 232, and the third interface 233 are connected to the spray port 234. The first interface 231 is used to introduce water flow, the second interface 232 is used to introduce a release agent, and the third interface 233 is used to introduce gas.

[0044] Specifically, when spraying is required, the first interface is closed, and the second interface 232 and the third interface 233 are opened. The second interface 232 introduces the release agent into the nozzle 23 through the pipeline, and then the third interface 233 simultaneously introduces compressed gas into the nozzle 23. At this time, the compressed gas provides the spraying power for the release agent in the nozzle 23, helping the release agent to be sprayed from the spray port 234 to the extrusion pad 11 in the form of a mist, a fine stream or a specific shape. By adjusting the pressure and flow rate of the compressed air, the spraying force and range can be controlled, so that the release agent can be sprayed more evenly onto the extrusion pad 11 after being sprayed from the spray port 234.

[0045] Similarly, when cooling is required for components in high-temperature areas, the second interface 232 is closed, and the first interface 231 and the third interface 233 are opened simultaneously. At this time, the water flow introduced through the first interface 231 merges with the compressed gas introduced through the third interface 233. The compressed gas provides the jet propulsion, helping the water to be sprayed from the nozzle 234 into the high-temperature area in a mist, fine stream, or specific form, thus cooling the components and preventing deformation or damage caused by overheating. Simultaneously, the water can also be used to remove residual release agent inside the nozzle 23, reducing the likelihood of the release agent solidifying and clogging the nozzle 23.

[0046] More specifically, it also includes three solenoid valves. During assembly, the three solenoid valves are connected to the first interface 231, the second interface 232, and the third interface 233 respectively through hoses, so as to control the opening and closing of the first interface 231, the second interface 232, and the third interface 233 respectively through the three solenoid valves, so that the equipment can spray water or isolation agent as needed, making the structure more intelligent.

[0047] It should be noted that the solenoid valve can be integrated with the back-end control system (such as PLC, DCS, etc.) to realize remote control of the opening and closing of the first interface 231, the second interface 232 and the third interface 233, making the whole structure more automated, reducing the need for manual intervention, reducing errors and accidents caused by improper operation or negligence, and improving production efficiency and safety.

[0048] Example 2,

[0049] like Figure 3 As shown, an extruder includes a body 10 and an extruder push-pull nozzle mechanism 20. An extrusion rod is provided inside the body 10, an extrusion pad 11 is connected to the extrusion rod, and a mounting bracket is installed on the outer periphery of the body 10.

[0050] In practical use, the mounting bracket is installed on the outer periphery of the machine body 10 and set on the side close to the extrusion pad 11. When it is necessary to spray the extrusion pad 11, simply start the drive component 21 to drive the nozzle 23 to move close to the extrusion pad 11, and then spray the release agent onto the extrusion pad 11 through the nozzle 23. There is no need to stop the machine or manually spray during the spraying process, realizing automatic spraying of the release agent, improving production efficiency, and making the operation safer.

[0051] After the release agent is sprayed, the drive unit 21 is activated again to drive the nozzle 23 away from the extrusion pad 11. This moves the nozzle 23 away from the high-temperature zone, increases the life of the nozzle 23, and prevents the release agent solution from solidifying in the nozzle 23 and causing blockage. The structure is more practical.

[0052] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
