Description

Technical Field

[0001] The invention belongs to the technical field of valve plate processing, and in particular relates to a metal cutting device for valve plate processing and a cutting method thereof. Background Art

[0002] The valve plate is a device used to control the flow of fluids, usually consisting of a valve body and a valve disc. The valve plate adjusts the flow or pressure by changing the cross-section of the pipeline to achieve the function of cutting off, opening or regulating the fluid in the pipeline. It is a fluid control device widely used in the fields of industry, chemical industry, petroleum, natural gas, etc. Metal cutting is a material removal and forming method in the metal forming process. The excess metal is cut off from the workpiece to be processed by the tool to obtain a part that meets the requirements of shape, dimensional accuracy and surface quality. Valve plate metal cutting refers specifically to the cutting process of the valve plate part, and its purpose is to make the valve plate meet the design requirements of geometry, dimensional accuracy and surface quality.

[0003] Conventional metal cutting devices used for valve plate processing are mainly composed of a cutting assembly, a workbench and a clamping assembly. When cutting, the clamping assembly is used to clamp the metal valve plate, and then the cutting assembly is used again to cut it. However, during the processing, due to the presence of the clamping assembly, it is difficult to use the cutting assembly to cut the clamped part, resulting in the need to frequently switch the clamping position of the clamping assembly during the entire processing process to meet the cutting process, and the overall cutting efficiency is low.

[0004] At the same time, when changing the clamping position, the cutting assembly needs to be operated to rise, and the dust cover needs to be operated to rise at the same time to avoid the impact of the cutting assembly on the operator. That is, each time the cutting position is switched and the clamping position affects the cutting, the device needs to be shut down and reset before it can be completed, which seriously affects the overall processing efficiency. Summary of the invention

[0005] The object of the present invention is to provide a metal cutting device and a cutting method for machining a valve plate, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a metal cutting device for processing a valve plate, comprising a base, a ring groove is provided at a position near the outer side surface of the top of the base, a support rod is movably connected at an equal angle inside the ring groove, a mounting seat is fixedly installed in the middle of the top of the base, a servo motor is fixedly installed in the middle of the top of the mounting seat, an electric push rod is fixedly installed at the output end of the servo motor, a movable plate is fixedly installed at the output end of the electric push rod, a workbench is provided directly above the movable plate, a clamping assembly is fixedly installed at an equal angle on the outer side surface of the movable plate, a limiting groove is provided on the outer side surface of the workbench, one end of the clamping assembly close to the workbench is movably connected to the limiting groove, the clamping assembly rotates relative to the limiting groove, a linkage frame located below the movable plate is fixedly sleeved on the outer side surface of the output shaft of the electric push rod close to the top, a dust cover is fixedly connected to the top of the linkage frame, a cutting assembly is fixedly connected to the top of the dust cover, and the support rod rotates circumferentially relative to the ring groove.

[0007] When performing metal cutting of the valve plate, the valve plate can be placed directly above the workbench. At this time, the device is in the initial state, that is, the movable plate is at the highest point, and the linkage frame, dust cover and cutting assembly are also at the highest point, that is, they are at a certain height from the workbench, which is used for the rapid placement of the metal valve plate. At the same time, the clamping assembly is also in the initial state, that is, the non-clamping state, completing the preparation before clamping.

[0008] As a further technical solution of the present invention, the cutting assembly includes an extension frame, the bottom end of the extension frame is connected to the top end of the dust cover, the top end of the extension frame is fixedly installed with a longitudinal linear guide rail, and the bottom end of the longitudinal linear guide rail is movably connected with a transverse linear guide rail.

[0009] As a further technical solution of the present invention, the transverse linear guide rail is displaced forward and backward relative to the longitudinal linear guide rail, and an adjusting rod is movably connected to the bottom end of the transverse linear guide rail. The adjusting rod is displaced left and right relative to the transverse linear guide rail, and an equipment seat is fixedly installed at the output end of the adjusting rod. The bottom end of the equipment seat is movably connected to a disc cutting machine located on the inner side of the dust cover.

[0010] During the clamping process of the valve plate, due to the shortening of the electric push rod, it can drive the linkage frame to move downward while driving the movable plate to descend. At this time, the dust cover located above the linkage frame moves downward accordingly, and drives the cutting assembly at the top to move downward. At this time, the longitudinal position of the disc cutter can be changed by adjusting the longitudinal linear guide rail, and the transverse position of the disc cutter can be changed by the transverse linear guide rail. The height of the disc cutter can be changed by adjusting the rod, and the disc cutter can be used to cut the metal valve plate to complete the cutting process. When the cutting is completed, the clamping limit of the metal valve plate by the clamping assembly can be released, that is, the electric push rod is extended, and the movable plate and the linkage frame automatically move upward, and at the same time drive the dust cover and the cutting assembly away from the workbench, automatically reset, and wait for the next cutting process.

[0011] By utilizing the device to clamp the metal valve plate, that is, when the clamping is completed, the cutting assembly and the dust cover can automatically drop to the cutting position, and the dust cover can block the cutting debris. After the cutting is completed, the dust cover and the cutting assembly can be automatically reset, that is, the cutting state is released. The whole process is automatically completed without manual adjustment, reducing the operating steps and improving the overall processing efficiency.

[0012] As a further technical solution of the present invention, the clamping assembly includes an extended guide rail, which is movably connected to the limiting groove. The extended guide rail is distributed at equal angles on the outer side of the workbench, and the extended guide rail rotates relative to the limiting groove.

[0013] As a further technical solution of the present invention, a guide block is movably clamped inside the extended guide rail, and a clamping plate is fixedly connected to the top of the guide block. A roller is movably mounted on one end of the clamping plate close to the workbench.

[0014] As a further technical solution of the present invention, the bottom end of the guide block is fixedly connected to a first fixed seat, and one end of the first fixed seat away from the guide block is movably connected to a connecting rod via a rotating shaft.

[0015] As a further technical solution of the present invention, one end of the connecting rod away from the first fixing seat is movably connected to the second fixing seat via a rotating shaft, and one side of the second fixing seat away from the connecting rod is connected to the outer side surface of the movable plate.

[0016] When the metal valve plate is placed on the workbench, the electric push rod can be turned on and controlled to shorten, and the movable plate will then drop, and a force will be applied to the clamping assembly at the same time. At this time, multiple connecting rods will move toward the middle, and a pulling force will be applied inward to the guide block, and multiple clamping plates will then move toward the middle of the workbench until the roller on the inner side of the clamping plate contacts the outer side of the metal valve plate, and the clamping process of the valve plate can be completed; After the processing is completed, the electric push rod can be controlled to extend, which can drive the multiple clamping plates to move away from each other and release the clamping process of the metal valve plate.

[0017] By utilizing the cooperation between the electric push rod and the clamping assembly, that is, utilizing the extension and contraction process of the electric push rod to act on the clamping assembly, the clamping and loosening process of the metal valve plate can be quickly completed, avoiding the more complicated clamping and loosening process of traditional devices, effectively reducing the operation time, and further improving the overall processing efficiency.

[0018] When the clamping is completed and the clamping position affects the cutting position, the servo motor can be turned on to drive the electric push rod to rotate. At this time, the movable plate above will rotate accordingly, and at the same time, the multiple clamping components on the outer side will be driven to rotate. At this time, the clamping component can rotate circumferentially relative to the limit groove, and the support rod at the bottom can rotate relative to the annular groove at the same time, until the clamping position no longer affects the cutting position, completing the entire cutting process of the metal valve plate.

[0019] By utilizing the clamping state of the clamping assembly and utilizing its coordination with the limit groove and the action of the roller, the device can quickly switch the clamping position while maintaining the clamping state, thus avoiding the problem that traditional devices need to repeatedly clamp and release to achieve a change in the clamping position. This effectively simplifies the operating steps, reduces adjustment time, and significantly improves cutting efficiency.

[0020] A cutting method of a metal cutting device for machining a valve plate, comprising the following steps: S1: When cutting, the metal valve plate to be cut can be placed on the top of the workbench. After the placement is completed, the electric push rod can be turned on and controlled to shorten, and the movable plate can be driven down. At this time, multiple connecting rods can be deflected toward the middle and exert a pulling force on the guide block; S2: At this time, multiple clamping plates are relatively close to each other and clamp the valve plate above the workbench to complete the clamping process. At this time, the outer side of the valve plate can contact between the rollers; S3: When the movable plate descends, the linkage frame, the dust cover and the cutting assembly also descend, and the device switches to the cutting state. The longitudinal linear guide rail, the transverse linear guide rail and the adjusting rod are controlled, and the three-axis direction of the disc cutting machine is controlled, and the disc cutting machine is used to cut the valve plate; S4: When the clamping position affects the cutting, the servo motor can be turned on to drive the movable plate to rotate. At this time, multiple clamping components will move circumferentially relative to the limit groove until they avoid the clamping position and complete the cutting process.

[0021] The beneficial effects of the present invention are as follows: 1. The present invention utilizes the clamping state of the clamping assembly, and utilizes the cooperation between the clamping assembly and the limit groove, as well as the function of the roller, so that the device can quickly switch the clamping position while maintaining the clamping state, thereby avoiding the problem that the traditional device needs to repeatedly clamp and release to achieve the clamping position change, effectively simplifying the operating steps, reducing the adjustment time, and significantly improving the cutting efficiency.

[0022] 2. The present invention utilizes the device to clamp the metal valve plate. That is, when the clamping is completed, the cutting assembly and the dust cover can automatically drop to the cutting position. At the same time, the dust cover can block the cutting debris. After the cutting is completed, the dust cover and the cutting assembly can be automatically reset, that is, the cutting state is released. The whole process is automatically completed without manual adjustment, reducing the operating steps and improving the overall processing efficiency.
