Description

Technical Field

[0001] This utility model relates to the field of plastic-coated steel pipe processing technology, specifically a grinding equipment for the production and processing of plastic-coated steel pipes. Background Technology

[0002] Plastic-coated steel pipe is a type of steel pipe whose surface has been coated with plastic. It has advantages such as corrosion resistance, wear resistance, and pressure resistance. Plastic-coated steel pipe is mainly used to transport liquids, gases, and other media, and is widely used in petroleum, chemical, water supply, drainage, natural gas and other fields. The outer plastic coating layer of plastic-coated steel pipe is made of polyethylene powder, and the inner plastic coating layer is made of epoxy resin powder, which can improve the service life and safety of the steel pipe.

[0003] During the processing of plastic-coated steel pipes, cutting equipment is usually used to cut the steel pipes to a certain length. The cut steel pipe end faces generally have poor uniformity. In environments with high installation precision, the steel pipe end faces need to be ground to ensure the uniformity of the steel pipe end faces. Existing grinding equipment generally uses a motor to drive the grinding wheel to rotate for grinding. However, this method cannot grind the inner and outer walls of the end face at the same time, which will result in poor grinding effect. Moreover, this method is also time-consuming and labor-intensive when dealing with a large batch of steel pipes. In order to solve the above problems, the inventor proposes a grinding equipment for the production and processing of plastic-coated steel pipes. Utility Model Content

[0004] In order to solve the problem that existing grinding equipment cannot grind the inner and outer walls of the port at the same time, and is time-consuming and labor-intensive, the purpose of this utility model is to provide a grinding equipment for the production and processing of plastic-coated steel pipes.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a grinding device for the production and processing of plastic-coated steel pipes, comprising a base plate, a ring body that can be lifted and lowered above the base plate, a guide ring that is rotatably connected to the side wall of the ring body, a rotating plate that is fixedly connected to the side of the guide ring facing away from the ring body, a motor that is disposed on the side of the rotating plate facing away from the guide ring, a screw that is fixedly connected to the output shaft end of the motor, a rotary cylinder that is disposed in the ring opening of the ring body, the output end of the rotary cylinder that is fixedly connected to the middle of the side wall of the rotating plate, a threaded sleeve that is threadedly connected to the side wall of the screw, a protruding rod that is fixedly connected to the side of the threaded sleeve facing away from the rotating plate, an adjusting rod that is fixedly connected to the side wall of the protruding rod, a ring sleeve that is sleeved on the side wall of the adjusting rod, an adjusting plate that is fixedly connected to the side wall of the ring sleeve, and a grinding block that is fixedly connected to the side wall of the adjusting plate.

[0006] Preferably, a protrusion is fixedly connected to the outer wall of the ring body, and electric cylinders are provided on both sides of the top surface of the base plate. The output shaft end of the electric cylinder is fixedly connected to the bottom surface of the protrusion. A pad is provided on one side of the base plate, and the pipe body is placed on the top surface of the pad. When grinding the pipe opening of the pipe body, the axial position of the pipe body is first determined by an external measuring tool to adjust the position of the indicator needle so that the indicator needle coincides with the axial position of the pipe body. After adjustment, the same batch of pipe bodies can be ground and used without further adjustment of the position of the indicator needle. No manual grinding is required, which improves grinding efficiency and reduces labor. The outer shell of the electric cylinder is fixedly connected to the top surface of the base plate. When the electric cylinder is started, the protrusion can move up and down under the action of the output shaft of the electric cylinder, which in turn can move the ring body up and down to adjust the height of the indicator needle so that the indicator needle coincides with the axial position of the pipe body.

[0007] Preferably, the rotary cylinder has a fixed frame on its side wall, and a connecting plate is fixedly connected to the outer side wall of the fixed frame. The end of the connecting plate away from the fixed frame is fixedly connected to the inner wall of the ring. The rotary cylinder is installed and fixed through the fixed frame and the connecting plate. When the rotary cylinder is started, the rotating plate rotates under the action of the output shaft of the rotary cylinder, so that the grinding block rotates to grind the inner and outer walls of the pipe body. A vertical rod is fixedly connected to the inner wall of the ring and to one side of the rotary cylinder. An indicator needle is fixedly connected to the middle of the side wall of the vertical rod. The indicator needle coincides with the axis of the ring, and the vertical rod coincides with the diameter of the ring. The indicator needle is located at the center of the ring so that the operator can find the axis of the ring.

[0008] Preferably, the motor has a base on its side wall, which is fixedly connected to the side wall of the rotating plate. There are two screws, symmetrically located on both sides of the motor, with opposite thread directions. A slider is fixedly connected to the side of the threaded sleeve facing the rotating plate. A slide rail is fixedly connected to the side wall of the rotating plate, with the slider corresponding to and slidably connected to the slide rail. The motor is mounted on the base. When the motor is started, the screws rotate under the action of the motor output shaft. Through the cooperation of the slider and the slide rail, the threaded sleeve can be translated, and under the action of the convex rod and the adjusting rod, the grinding block can be positioned. The adjustment mechanism is designed to accommodate pipe bodies of different diameters. A threaded hole is provided through the side wall of the ring, and a fastening knob is located on one side of the ring. The knob has a threaded rod that corresponds to and engages with the threaded hole. Each adjusting rod has two grinding blocks, made of the same material as the grinding wheel. The grinding blocks are L-shaped. During grinding, the fastening knob is loosened, and the position of the adjusting plate is adjusted so that the two grinding blocks contact the inner and outer walls of the pipe body, respectively, and the L-shaped opening of the grinding blocks contacts the pipe end of the pipe body, thus grinding the pipe opening and the inner and outer walls of the pipe end.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the ring body can be raised and lowered to adjust the position of the indicator needle so that the indicator needle coincides with the axis of the pipe body. After adjusting the height, the same batch can be ground without additional adjustment. The cooperation between the slider and the slide rail allows the threaded sleeve to move horizontally. The action of the convex rod and the adjusting rod can adjust the position of the grinding block to match the pipe body with different diameters. By adjusting the position of the adjusting plate, the two grinding blocks are made to contact the inner and outer walls of the pipe body respectively, and the L-shaped opening of the grinding block is made to contact the pipe end of the pipe body. Activating the rotary cylinder allows the rotating plate to rotate smoothly, so that the grinding blocks rotate to grind the inner and outer walls of the pipe body opening and end. Thus, manual grinding is not required, improving grinding efficiency and reducing labor. Attached Figure Description

[0019] By adopting the above technical solution, a pad 26 is provided on one side of the base plate 1, and the pipe body 25 is placed on the top surface of the pad 26. When grinding the pipe opening of the pipe body 25, the axial position of the pipe body 25 is first determined by an external measuring tool to adjust the position of the indicator needle 12 so that the indicator needle 12 coincides with the axis of the pipe body 25. After adjustment, the same batch of pipe bodies 25 can be ground and used without further adjustment of the position of the indicator needle 12. No manual grinding is required, which improves grinding efficiency and reduces labor. The outer shell of the electric cylinder 2 is fixedly connected to the top surface of the base plate 1. When the electric cylinder 2 is started, the protrusion 4 can move up and down under the action of the output shaft of the electric cylinder 2, which in turn can move the ring 3 up and down to adjust the height of the indicator needle 12 so that the indicator needle 12 coincides with the axis of the pipe body 25.

[0025] By adopting the above technical solution, the motor 13 is installed on the base 14. When the motor 13 is started, the screw 15 rotates under the action of the output shaft of the motor 13. Through the cooperation of the slider 17 and the slide rail 7, the threaded sleeve 16 can be translated.
