Description

Technical Field

[0001] The invention relates to the technical field of seamless steel pipe processing, in particular to a fully automatic seamless steel pipe head feeding and grinding device. Background Art

[0002] Seamless steel pipe is a tubular product without welded seams. It is formed by a whole piece of metal (usually steel) through perforation, hot rolling, cold rolling or cold drawing. This type of steel pipe has no welds on the surface, so it has higher strength and pressure resistance, better corrosion resistance and longer service life. Seamless steel pipes can be divided into thick-walled seamless steel pipes and thin-walled seamless steel pipes according to different uses. They are widely used in many fields, including petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, high-precision structural steel pipes for the automotive and aviation industries, and various fluid delivery pipelines.

[0003] The seamless steel pipe end grinding device is a device specially designed for grinding the ends (ends) of seamless steel pipes. Equipped with grinding tools such as grinding wheels, grinding discs or brushes for the actual grinding operation, the main function of this device is to finely grind both ends of the steel pipe during the production of seamless steel pipes to remove any burrs, unevenness or oxide layers left during the cutting or processing process, ensure the flatness and finish of the steel pipe end face, thereby improving product quality and the reliability of subsequent processing.

[0004] The seamless steel pipe head grinding device in the prior art usually requires manual loading and cannot operate fully automatically and continuously. Although it meets the use requirements to a certain extent, it is found in actual use that the processing process lacks continuity and the utilization rate of the equipment is not high. After each loading, it is necessary to wait for the operator to prepare the next steel pipe, resulting in unnecessary downtime and low production efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a fully automatic feeding and grinding device for seamless steel pipe heads to solve the problems raised in the above-mentioned background technology.

[0011] Preferably, the circulating throwing mechanism includes a mounting plate, two groups of fixed blocks are fixedly installed on the upper and lower sides of the mounting plate, an inclined groove is opened on the top of the fixed block, a positioning groove is opened on the bottom of the inclined groove, and a material baffle plate is arranged on the side of the positioning groove away from the inclined groove, and four groups of fixed blocks are axially symmetrically installed on the upper and lower sides of the mounting plate, two in a group.

[0012] Preferably, a second motor is fixedly mounted on one side of the third mounting frame, and an output shaft of the second motor is fixedly connected to one side of the mounting plate via a coupling.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the fully automatic seamless steel pipe head feeding and grinding device;

[0014] 1. The steel pipe to be processed is stored in a material storage box, and the steel pipe to be processed falls on the top of the movable plate under the action of the inclined plate. At this time, the driving gear is driven to rotate by the first motor, so that the driving gear drives the driven gear to rotate, and then the two groups of half gears are alternately meshed with the double-sided rack, so that the double-sided rack is moved back and forth on one side of the material storage box, and then the first mounting frame is driven to move back and forth, and finally the three groups of movable plates are alternately displaced on one side of the fixed plate. The steel pipe to be processed falls on the top of the movable plate under the action of the inclined plate, and the steel pipe to be processed is gradually displaced upward under the cooperation of the movable plate, the fixed plate and the guide groove, and finally falls on the top of the grinding mechanism for grinding;

[0015] 2. The steel pipe is guided to fall into the top of the positioning groove through the provided inclined groove and the displacement of the steel pipe is limited by the positioning groove. At this time, the linear guide rail assembly is started to drive the grinding assembly to move toward the circulating throwing mechanism to grind the pipe head of the steel pipe. After grinding, the second motor is started to flip the mounting plate counterclockwise. During the flipping process, the steel pipe falls off from the two sets of fixed blocks on the top of the mounting plate and is unloaded under the guidance of the slide plate, while the fixed block at the bottom of the mounting plate is flipped to the top to fix the next steel pipe. In summary, the equipment completes loading, fixing, grinding and unloading continuously, which solves the problem of low equipment utilization. After each loading, it is necessary to wait for the operator to prepare the next steel pipe, which causes unnecessary downtime and low production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

By axially symmetrically installing the four groups of fixed blocks 2102 in groups of two on the upper and lower sides of the mounting plate 2101, when the mounting plate 2101 rotates, the two fixed blocks 2102 in groups of two can alternately complete the tasks of receiving and throwing materials.

[0027] The specific implementation method is as follows: the steel pipe is guided to fall into the top of the positioning groove 2104 through the inclined groove 2103 and the displacement of the steel pipe is limited by the positioning groove 2104. At this time, the linear guide rail assembly 202 is started to drive the grinding assembly 203 to move toward the circulating throwing mechanism 210 to grind the pipe head of the steel pipe. After grinding, the second motor 205 is started to flip the mounting plate 2101 counterclockwise.

The steel pipe to be processed falls on the top of the movable plate 104 under the action of the inclined plate 102, and the steel pipe to be processed is gradually displaced upward under the cooperation of the movable plate 104, the fixed plate 105 and the guide groove 107, and finally falls on the top of the grinding mechanism 2 for grinding;

[0029] The steel pipe is guided to fall into the top of the positioning groove 2104 through the inclined groove 2103 and the displacement of the steel pipe is limited by the positioning groove 2104. At this time, the linear guide assembly 202 is started to drive the grinding assembly 203 to move toward the circulating throwing mechanism 210 to grind the pipe head of the steel pipe. After grinding, the second motor 205 is started to flip the mounting plate 2101 counterclockwise. During the flipping process, the steel pipe falls off from the two groups of fixed blocks 2102 on the top of the mounting plate 2101 and is unloaded under the guidance of the slide plate 204. The fixed block 2102 at the bottom of the mounting plate 2101 flips to the top to fix the next steel pipe. In summary, the equipment completes loading, fixing, grinding and unloading continuously, which solves the problem of low equipment utilization. After each loading, it is necessary to wait for the operator to prepare the next steel pipe, which causes unnecessary downtime and low production efficiency.
