Description

Technical Field

[0001] This utility model relates to a silicone rubber strip cutting device for pump body sealing rings, belonging to the field of pump technology. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps are generally classified into three types according to their working principle: positive displacement pumps, dynamic pumps, and other types. Besides classification by working principle, they can also be classified and named according to other methods. For example, according to the driving method, they can be divided into electric pumps and water turbine pumps; according to structure, they can be divided into single-stage pumps and multi-stage pumps; and according to application, they can be divided into boiler feed pumps and metering pumps. A cutting device is required when processing the silicone rubber sealing ring of the pump body.

The drive motor 303 outputs, causing the lead screw block 305 to drive the cutting blade 307 to move. This effectively prevents the silicone rubber strip from changing position due to contact with the cutting blade 307 during cutting, thus affecting the normal cutting of the silicone rubber strip. At the same time, the displacement of the cutting blade 307 can cut different areas of the silicone rubber strip, cutting silicone rubber strips of different sizes.

[0032] In this embodiment, preferably, the front and rear sides of the top of the workbench 1 are provided with sliding grooves 207, and the left and right sides of the bottom of the two clamping plates 206 are slidably connected to the inner cavity of the four sliding grooves 207. By setting the sliding grooves 207, the movement of the clamping plates 206 can be limited to avoid deviation when they move.

[0033] In this embodiment, preferably, the front and rear sides of the bottom of the workbench 1 are provided with moving grooves 208, and the two mounting rods 205 pass through the inner cavity of the two moving grooves 208 and extend to the top of the workbench 1.

[0036] In this embodiment, preferably, a limiting groove 309 is provided at the top of the inner cavity of the hydraulic cylinder 301, and the top of the screw block 305 is slidably connected to the inner cavity of the limiting groove 309. By setting the limiting groove 309, the movement of the screw block 305 can be limited, so as to prevent the screw block 305 from rotating synchronously with the screw 304.

[0039] When this utility model is in operation: First, the silicone rubber strip is placed on the top of the workbench 1. Then, the cylinder 201 retracts downward, and at this time, the lifting block 202 moves downward in sync. The lifting block 202 and the movable rod 203 cooperate with each other. The movable rod 203 drives the moving plate 204 to move inward. At this time, the moving plate 204 drives the mounting rod 205 and the clamping plate 206 to move inward in sync. The clamping plate 206 clamps and fixes the silicone rubber strip.

[0040] Subsequently, based on the required size of the silicone rubber strip to be cut, the output of the drive motor 303 causes the lead screw 304 to rotate. The lead screw 304 drives the lead block 305 to move, so that the lead block 305 synchronously drives the fixed rod 306 and the cutting blade 307 to move. When the cutting blade 307 moves to the vertical direction of the required cutting position of the silicone rubber strip, the hydraulic cylinder 301 extends, so that the housing 302 drives the components on its surface to move downward synchronously with the cutting blade 307, and the cutting blade 307 realizes the cutting work of the silicone rubber strip.
