Description

Technical Field

[0001] The utility model belongs to the technical field of valve disc processing, and in particular relates to a processing device for a valve disc of a low-leakage sealing breathing valve. Background Art

[0002] When the breathing valve opening pressure requirement is low, the breathing valve disc cannot use a large-mass valve disc machined from a machine, and can only use a stretched valve disc made of stainless steel sheet. Since the rough material itself has certain internal stress, the stretched surface flatness is often poor. To solve this problem, the valve disc is usually pressed at high temperature. The valve disc will release the internal stress at high temperature and can be demolded after a period of pressure maintenance. However, since the temperature of the valve disc is high after pressing, the valve disc cannot be directly taken out for cooling. A structure that can cool the valve disc is now proposed. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a processing device for a valve disc of a low-leakage sealing breathing valve, which solves the above-mentioned problems.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a processing device for a low-leakage sealed breathing valve disc, including a frame, and also including: a demolding assembly for lifting the valve disc after hot pressing; the demolding assembly includes a lower template, a top plate and a push rod, the lower template is fixedly connected to the frame, the top plate is slidably connected to the lower template, and the two push rods are symmetrically hinged on the top plate.

[0005] Beneficial Effects

[0006] The utility model provides a processing device for a low-leakage sealing breathing valve disc, which has the following beneficial effects compared with the prior art:

[0007] The relevant technicians start the motor, so that the gear drives the main shaft fixed at its axis to start rotating, so that the worm fixed on the main shaft rotates synchronously, and the worm drives the worm wheel meshing with it to start rotating, so that the reciprocating screw B fixed at the axis of the worm wheel rotates synchronously, so that the reciprocating screw A fixed on the reciprocating screw B rotates synchronously, so that the reciprocating screw B and the slide cylinder threadedly connected on the reciprocating screw A start to perform linear reciprocating motion along the connection between them and the frame, so that the slide cylinder drives the top rod hinged to it to start moving synchronously, so that the top rod starts to push the top plate hinged to it, thereby the top plate The valve disc after hot pressing is lifted, and the eccentric wheel fixed on the main shaft rotates synchronously at the same time, so that the push rod A connected to the eccentric part of the eccentric wheel starts to move in a circular motion, so that the push rod A pushes the slide hinged to it, and the slide starts to move linearly along the slide bar, thereby contacting the valve disc through the push plate and pushing it away from the lower template. At this time, the top plate continues to rise and pushes the push plate to start sliding longitudinally, so that the push plate can stably push the valve disc away from the lower template. When the valve disc is mostly off the top plate, the slide moves synchronously to the end point and starts to rotate in the opposite direction. At this time, the push plate synchronously pushes the valve disc to the water pool on the side of the frame for cooling. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0014] See also Figures 1 to 3, provided in one embodiment of the utility model, is a processing device for a low leakage sealing breathing valve disc, comprising a frame 101, and also comprising:

[0015] Demolding component 2, used to lift the valve disc after hot pressing;

[0016] The demoulding assembly 2 includes a lower template 201, a top plate 202 and a push rod 203. The lower template 201 is fixedly connected to the frame 101, the top plate 202 is slidably connected to the lower template 201, and two push rods 203 are symmetrically hinged on the top plate 202.

[0017] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific top rod 203 described in the above embodiments. For example, the top rod 203 should be made of a one-piece processed material. The purpose of this setting is to prevent the top rod 203 from being broken by stress, and the hinges at both ends should be further hardened and reinforced.

[0018] Specifically, the other ends of the two push rods 203 are respectively hinged with slide cylinders 204 , and the two slide cylinders 204 are slidably connected in the frame 101 .

[0019] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific slide 204 described in the above embodiments. For example, a damping rubber strip is provided at the connection between the slide 204 and the frame 101. The purpose of this arrangement is to increase the sliding damping through such placement and prevent abnormal noise during sliding.

[0020] Specifically, a reciprocating screw A205 is rotatably connected to the frame 101, and the other end of the reciprocating screw A205 is fixedly connected to the reciprocating screw B206. The reciprocating screw B206 is rotatably connected to the frame 101, and the reciprocating screw A205 and the reciprocating screw B206 have opposite screw directions.

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solution, they are not limited to the specific rack 101 described in the above embodiment. For example, a water tank on the side of the rack 101 is provided with a water injection pipe. The purpose of this arrangement is to facilitate the injection and drainage of water into the water tank in this way.

[0022] Specifically, the two slide cylinders 204 are respectively threadedly connected to the reciprocating screw A205 and the reciprocating screw B206 , and the reciprocating screw B206 is fixedly connected with a worm wheel 207 , and the worm wheel 207 is meshingly connected with the worm 208 .

[0023] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific reciprocating screws A205 and B206 described in the above embodiments. For example, the reciprocating screws A205 and B206 are reciprocating screws. The purpose of this setting is that when the slider threaded on the reciprocating screw moves to one end, the direction of movement of the slider can be quickly changed by continuing to rotate in the same direction of the controller.

[0024] Specifically, the worm 208 is fixedly connected to the main shaft 209 , the main shaft 209 is rotatably connected to the frame 101 , and an eccentric wheel 301 is fixedly connected to the main shaft 209 .

[0025] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific main shaft 209 described in the above embodiments. For example, a bearing ring should be provided at the connection between the main shaft 209 and the frame 101. The purpose of this arrangement is to reduce the friction encountered during rotation in this way, thereby preventing the shaft from breaking.

[0026] Specifically, the eccentric wheel 301 is rotatably connected to a push rod A302 at its eccentric position, and the other end of the push rod A302 is hinged on the slide plate 303 .

[0027] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific slide plate 303 described in the above embodiments. For example, a damping rubber ring is provided at the connection between the slide plate 303 and the slide rod 305. The purpose of this setting is to facilitate smooth sliding in this way.

[0028] Specifically, the slide plate 303 is slidably connected to the slide bar 305 , the slide bar 305 is fixedly connected to the frame 101 , the slide plate 303 is slidably connected to the push plate 304 , and a damping rubber strip is provided at the connection between the slide plate 303 and the push plate 304 .

[0029] Specifically, a gear 306 is fixedly connected to the main shaft 209 , and the gear 306 is meshedly connected with a gear fixedly assembled on the output shaft of the motor 307 , and the motor 307 is fixedly connected to the frame 101 .

[0030] For the above example, those skilled in the art should be aware that when implementing the above technical solution, they are not limited to the specific motor 307 described in the above embodiment. For example, the motor 307 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the lifting speed of the top plate 202 in this way.

[0031] In the embodiment of the utility model, the relevant technicians start the motor 307, so that the gear 306 drives the main shaft 209 fixedly connected at its axis to start rotating, so that the worm 208 fixedly connected to the main shaft 209 rotates synchronously, and the worm 208 drives the worm wheel 207 meshing with it to start rotating, so that the reciprocating screw B206 fixedly connected at the axis of the worm wheel 207 rotates synchronously, so that the reciprocating screw A205 fixedly connected to the reciprocating screw B206 rotates synchronously, and the reciprocating screw B206 and the slide cylinder 204 threadedly connected to the reciprocating screw A205 start to perform linear reciprocating motion along the connection between them and the frame 101, so that the slide cylinder 204 drives the top rod 203 hinged thereto to start synchronous motion, so that the top rod 203 starts to push the top plate 202 hinged thereto, Thereby, the hot-pressed valve disc on the top plate 202 is lifted, and at the same time, the eccentric wheel 301 fixedly connected to the main shaft 209 rotates synchronously, so that the top rod A302 connected to the eccentric part of the eccentric wheel 301 starts to move in a circular motion, so that the top rod A302 pushes the slide plate 303 hinged thereto, so that the slide plate 303 starts to move linearly back and forth along the slide bar 305, thereby contacting the valve disc through the push plate 304 and pushing it away from the lower template 201. At this time, the top plate 202 continues to rise and pushes the push plate 304 to start longitudinal sliding, so that the push plate 304 can stably push the valve disc away from the lower template 201. When the valve disc is mostly detached from the top plate 202, the slide cylinder 204 moves synchronously to the end point and starts to rotate in the opposite direction. At this time, the push plate 304 synchronously pushes the valve disc into the water pool on the side of the frame 101 for cooling.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0034] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0035] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0036] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
