Description

Cutting device for seamless steel pipe production

technical field

The utility model belongs to the technical field of mechanical processing, in particular to a cutting device for seamless steel pipe production.

Background technique

At present, due to the simple, convenient and fast process of steel processing and production and construction and installation, it has become an important material component in the building structure system, and thus is widely used in various fields of national economic construction. Especially steel pipes are more and more widely used in our industrial production. Fast and efficient processing of steel pipes is a difficult problem that must be overcome to improve production efficiency. In the field of mechanical manufacturing, the steel pipe needs to be cut according to the required size during the processing process. The existing steel pipe cutting device has a complex structure and troublesome operation, and it is difficult to cut the steel pipe quickly and efficiently. The existing steel pipe cutting device usually places the steel pipe on the clamping mechanism of the cutting saw blade, then manually measures the length of the required steel pipe and marks it on the steel pipe, and then clamps and cuts the steel pipe. When cutting each section of steel pipe, personnel are required to measure the length of the required steel pipe in advance. The operation process is complicated, resulting in low work efficiency and increasing the labor intensity of the operator.

Utility model content

The purpose of the utility model is to provide a cutting device for seamless steel pipe production, which can efficiently and quickly realize the cutting of steel pipes with different length requirements.

In order to achieve the above purpose, the basic solution of the present utility model is: a cutting device for seamless steel pipe production, including a workbench, on which a feeding mechanism for conveying steel pipes and a cutting mechanism for cutting steel pipes are arranged horizontally, and positioning mechanism, the positioning mechanism is located on the worktable on the side of the cutting mechanism away from the feeding mechanism, the positioning mechanism includes a motor and a transmission structure, the transmission structure is provided with a positioning plate for clamping steel pipes, and the transmission structure is driven by the motor. The positioning plate moves horizontally. The positioning plate is equipped with a distance measuring sensor. The output shaft of the motor is connected with a rack and pinion structure. The rack is located on the workbench and is perpendicular to the output shaft of the motor. The push rod of the steel pipe, the push rod is located on one side of the cutting mechanism.

The working principle of the basic solution is: when using the device, the motor is started, and the motor drives the positioning plate to move horizontally on the workbench through the transmission structure. Since the positioning disc is provided with a distance measuring sensor, the positioning disc can measure the distance between the positioning disc and the cutting mechanism. During the movement of the positioning disc, when the distance between the positioning disc and the cutting mechanism reaches a certain value, that is, the value measured by the distance measuring sensor is equal to the length of the steel pipe to be cut, the motor is stopped. Now the distance between the positioning disc and the cutting mechanism is equal to the length of the required steel pipe. Then the steel pipe is conveyed to the bottom of the cutting mechanism through the feeding mechanism, so that the end of the steel pipe is positioned at the positioning plate, and the positioning plate clamps the steel pipe. At this time, the length of the steel pipe between the cutting mechanism and the positioning plate is equal to the length of the required steel pipe. Then start the cutting mechanism to cut the steel pipe, and the cut steel pipe will be located on the positioning plate. Then the positioning plate unclamps the steel pipe, and the starting motor drives the positioning plate to reset through the transmission structure. Since the output shaft of the motor is connected with a rack and pinion structure, the rack will move linearly when the motor drives the positioning disc to reset. Since the rack is horizontally located on the workbench and perpendicular to the output shaft of the motor, the rack will move towards the steel pipe; since the rack is equipped with a push rod for pushing the steel pipe, the movement of the rack will drive the push rod to move. Thereby push rod can promote the steel pipe that is cut off, and makes the steel pipe that is cut off be pushed out working area, realizes the automatic unloading of steel pipe. Then adjust the sensing distance of the distance measuring sensor to make the distance measuring sensor adapt to the length of the steel pipe required for the next section.

The beneficial effect of this basic scheme is that: this scheme realizes the fixed-length cutting of the steel pipe by setting the positioning plate and the distance measuring sensor, improves the working efficiency and reduces the labor intensity of the personnel. At the same time, the positioning plate can also be used for clamping the steel pipe, so that the steel pipe will not shake during the cutting process, which improves the cutting accuracy and ensures the quality of the steel pipe. In this scheme, by setting a rack and pinion structure and setting a push rod on the rack, the automatic blanking of steel pipes is realized during the reset process of the positioning plate, which reduces the steps of manual blanking, improves work efficiency, and reduces the labor of personnel. strength.

As a further improvement of the solution, the feeding mechanism includes a pair of vertically opposite conveying rollers with an adjustable gap and a conveying motor that drives the conveying rollers to rotate. The advantage is that by setting the conveying roller up and down and the gap is adjustable, the two conveying rollers can clamp the steel pipe, so that the conveying roller can not only be used to convey the steel pipe but also be used as a clamping structure to clamp the steel pipe to prevent shaking when the steel pipe is cut , Improve the cutting quality of steel pipe.

As a further improvement of this solution, the cutting mechanism includes a support frame fixedly connected to the workbench and a vertical cylinder, the piston rod of the cylinder is hinged with a connecting rod, the middle part of the connecting rod is hinged on the support frame, and the connecting rod A cutting motor is fixedly connected to the end away from the cylinder, and a cutting saw blade is fixedly connected to the output shaft of the cutting motor. With such an arrangement, the lifting motion of the cutting saw blade is driven by the cylinder, and the structure is simple and the cost performance is high.

As a further improvement of this solution, a V-shaped cutting groove is provided on the workbench, and the cutting groove is located directly below the cutting saw blade. The advantage is that the V-shaped cutting groove can make the steel pipe stably located on the cutting groove, prevent the shaking of the steel pipe during cutting, and improve the cutting quality of the steel pipe. At the same time, the cutting groove can collect the debris generated when the steel pipe is cut, providing a good working surroundings.

As a further improvement of this solution, the conveying roller is a conveying roller made of rubber. The advantage is that the rubber has high elasticity, so that the conveying roller can be fully attached to the steel pipe. At the same time, the roughness of the conveying roller is increased to increase the friction between the steel pipe and the conveying roller, so that the steel pipe can be stably conveyed between the two conveying rollers. At the same time, the conveying roller made of rubber will not damage the surface of the steel pipe, which ensures the quality of the steel pipe.

As a further improvement of this solution, a pair of guide rollers are provided on the left and right sides of the feeding mechanism, and the guide rollers are rotatably connected to the workbench. The advantage is that the steel pipe can move forward straightly by setting the guide roller, which improves the cutting precision.
