Description

Stainless steel seamless pipe cutting equipment

technical field

The invention relates to a steel pipe processing equipment, in particular to a stainless steel seamless pipe cutting equipment.

Background technique

Stainless steel seamless steel pipe is a long strip of steel with a hollow section and no seams around it. It is a steel pipe that is resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel pipe. The processing flow of stainless steel seamless pipe includes multiple cutting steps. Due to the wide range of application fields of stainless steel seamless pipes, the span of their pipe diameters is also very large; if you want to complete the cutting of stainless steel seamless pipes with larger diameters, you must purchase large-scale cutting equipment that is compatible with them. Due to the small quantity of large-diameter stainless steel seamless pipes, if a large-scale cutting equipment is purchased for a small quantity of large-diameter stainless steel seamless pipes, the production cost and procurement cost of the enterprise will be greatly increased. Therefore, how to realize cutting equipment with lower cost and can also cut large-diameter stainless steel seamless pipes has become a problem that enterprises need to solve urgently. Based on the above problems, the present invention is conceived.

Contents of the invention

The purpose of the present invention is to provide a stainless steel seamless pipe cutting equipment, which has low cost and can realize the cutting of large-diameter steel pipes, so as to reduce the production cost and purchase cost of the enterprise.

The above-mentioned technical purpose of the present invention is achieved through the following technical solutions: a stainless steel seamless pipe cutting equipment, including a frame and a cutting machine, the frame includes a feeding rack and a fixing seat located on one side of the feeding rack, A movable assembly is arranged above the feeding rack, and the movable assembly is used for the steel pipe to move above the feeding rack. A limit assembly and a driving device with gravity potential energy and used to drive the steel pipe to rotate are arranged on the feeding rack. The limit assembly cooperates with The radial movement of the steel pipe is restricted by a driving device with gravitational potential energy. The cutting machine is slidably arranged on the fixed seat and is connected with a second driving assembly that drives the cutting machine to reciprocate.

By adopting the above-mentioned technical scheme, the steel pipe to be cut is placed on the top of the feeding rack, and the movement above the feeding rack is realized under the action of the movable component, and the limit component is controlled to form a limit for the steel pipe and then push the steel pipe toward the fixed seat. Side movement is used to adjust the position of the steel pipe to be cut. After adjusting the position of the steel pipe to be cut, the gravitational potential energy is applied to the steel pipe after the limit through the driving device to cooperate with the limit component to limit the radial movement of the steel pipe and prevent the steel pipe from being cut during the cutting process. Displacement occurs. Then, the steel pipe is driven to rotate in a circumferential direction by a driving device that applies gravitational potential energy to the steel pipe, and then the second driving component is used to drive the cutting machine close to the steel pipe to complete the circular cutting operation of the large-diameter steel pipe. The small cutting machine is not affected by the diameter of the steel pipe through this rotating cutting method, and the cutting operation of the steel pipe with a large diameter can be completed. The feeding structure of the rotating steel pipe is adapted to a small cutting machine to reduce the production cost and procurement cost of the enterprise.

By adopting the above-mentioned technical scheme, the flexibility of the steel belt and the elasticity of the transmission belt are adapted to each other to adapt to the driving of steel pipes with different diameters. The third driving component drives the magnet close to the steel belt, and the steel belt is absorbed by the magnet to form an outward direction on the transmission belt. The expansion force of the pulling can avoid the phenomenon that the steel pipe cannot pass through the transmission belt smoothly due to the sagging of the transmission belt. Moreover, the nature of the magnet can realize convenient separation from the steel belt, so as to ensure the normal rotation of the transmission belt and avoid structural interference.

It is further set that: the transmission belt is a synchronous belt, including a synchronous pulley arranged on the output shaft of the second drive motor and a limiter located below the synchronous pulley for limiting the synchronous belt from detaching from the synchronous pulley and moving with the second drive motor When the timing belt engages the timing pulley, a gap is formed between the timing belt and the limiting plate.

By adopting the above technical scheme, the setting of the limit plate can avoid the separation of the transmission belt and the synchronous pulley, ensure that the two form a stable transmission, and ensure that the transmission belt is not rubbed by the limit plate during the rotation process through the formed gap. Ensure the smooth rotation of the transmission belt and ensure its service life.

By adopting the above technical scheme, the two magnetic blocks and the synchronous pulley form a triangular expansion for the transmission belt, so as to ensure the smooth penetration of the steel pipe into the transmission belt; and realize the two magnetic blocks through the winding motor and the connecting rope. The advanced asynchronous lifting control can better adapt to the shape of the sagging and special-shaped transmission belt, and has better practicability. That is to say, when one of the magnets absorbs the steel strip to form a position, this structure can also control the other magnetic block to descend independently to carry out the adsorption operation with the steel strip.

It is further set as follows: the limit assembly includes two limit rods moving toward or back, a clamping area formed between the two limit rods for placing steel pipes, a rotation setting on the loading rack and connecting two limit rods The two-way screw of rod and the fourth motor that drives the two-way screw to rotate.

By adopting the above technical solution, the fourth motor drives the bidirectional screw to rotate, and the rotating bidirectional screw controls the two limit rods to move synchronously towards or away from each other, so as to constrain the steel pipe.

It is further provided that: the second driving assembly includes a threaded screw that is arranged on the fixed seat and is screwed with the cutting machine, and a fifth motor that drives the screw to rotate.

By adopting the above technical solution, the fifth motor drives the screw to rotate to control the reciprocating motion of the cutting machine to complete the cutting operation on the steel pipe.

It is further set that: the movable assembly includes a number of slots distributed on the loading frame and having an upward opening, and balls rolling in each slot, and a gap is formed between each slot wall and the balls.
