Description

TECHNICAL FIELD

[0001] The present application relates to a steel pipe processing equipment, in particular to a stainless steel seamless pipe cutting equipment. BACKGROUND

[0002] The stainless steel seamless pipe is a long strip steel material with hollow section and no joint on the periphery. It is a steel pipe resistant to air, steam, water and other weak corrosive media, and acid, alkali and salt and other chemical etching media corrosion, also known as stainless acid-resistant steel pipe. The processing flow of the stainless steel seamless pipe includes multiple cutting steps. Since the application field of the stainless steel seamless pipe is very wide, the span of the pipe diameter is also very large. In order to complete the cutting of the large-diameter stainless steel seamless pipe, a large cutting equipment needs to be purchased. If a large cutting equipment is purchased for a small quantity of large-diameter stainless steel seamless pipe, the production cost and procurement cost of the enterprise will be greatly increased. Therefore, how to realize the cutting of the large-diameter stainless steel seamless pipe by using a low-cost cutting equipment has become an urgent problem to be solved by the enterprise. According to the above problem, the present application is conceived. SUMMARY

[0003] The purpose of the present application is to provide a stainless steel seamless pipe cutting equipment, which is low in cost and can realize the cutting of large-diameter steel pipe, so as to reduce the production cost and procurement cost of the enterprise.

[0004] The above technical purpose of the present application is realized by the following technical scheme: a stainless steel seamless pipe cutting equipment, comprising a rack and a cutting machine, the rack comprises a feeding frame and a fixed seat on one side of the feeding frame, an active assembly is arranged above the feeding frame, the active assembly is used for the movement of the steel pipe above the feeding frame, a limiting assembly and a driving device with gravitational potential for driving the rotation of the steel pipe are arranged on the feeding frame, the limiting assembly cooperates with the driving device with gravitational potential to limit the radial movement of the steel pipe, and the cutting machine is slidably arranged on the fixed seat and connected with a second driving assembly for driving the reciprocating movement of the cutting machine.

[0005] By adopting the technical scheme, the steel pipe to be cut is placed above the feeding rack, and is moved above the feeding rack under the action of the movable assembly, and the limiting assembly is controlled to limit the steel pipe and then push the steel pipe to move towards the side of the fixed seat to adjust the cutting position of the steel pipe. After the cutting position of the steel pipe is adjusted, the driving device is used to apply gravity potential to the limited steel pipe to cooperate with the limiting assembly to limit the radial movement of the steel pipe, so that displacement of the steel pipe during cutting is avoided. Then, the driving device applying gravity potential to the steel pipe is used to drive the steel pipe to rotate circumferentially, and the second driving assembly is used to drive the cutting machine to approach the steel pipe to complete the ring cutting operation on the large-diameter steel pipe. By the rotating cutting mode, the small cutting machine can be used to cut the large-diameter steel pipe without being affected by the diameter of the steel pipe. The feeding structure for rotating the steel pipe is used to adapt to the small cutting machine to reduce the production cost and procurement cost of the enterprise.

[0006] Further, the driving device comprises an elastic transmission belt through which the steel pipe passes, a second driving motor which is arranged to slide up and down on the feeding rack and drives the transmission belt to rotate, a second control member which controls the second driving motor to slide up and down, and an expansion assembly which is used to expand the transmission belt to allow the steel pipe to pass into the transmission belt, and the transmission belt moves with the second driving motor.

[0007] By adopting the technical scheme, the expansion assembly expands the transmission belt to allow the steel pipe to smoothly pass into the inner ring of the transmission belt. Then, the second control member controls the second driving motor to drive the transmission belt to move downward, and the weight of the second driving motor is used to apply a force to the transmission belt against the steel pipe. Then, the second driving motor drives the transmission belt to rotate. Since a large friction force is formed between the transmission belt and the steel pipe, the steel pipe is realized to rotate circumferentially above the feeding rack, so as to complete the driving operation on the steel pipe.

[0008] Further, the expansion assembly comprises a steel belt which is fixedly arranged on the outer peripheral wall of the transmission belt, at least one magnetic block which is located above the steel belt, and a third driving assembly which drives the magnetic block to slide up and down, and the magnetic block is attracted to the steel belt to form linkage.

[0009] By adopting the technical scheme, the flexibility of the steel belt and the elasticity of the transmission belt form mutual adaptation to adapt to the driving of steel pipes with different diameters. The third driving assembly drives the magnet to approach the steel belt, and the magnet is used to attract the steel belt to form an expansion force to pull the transmission belt outward, so as to avoid the phenomenon that the steel pipe cannot smoothly pass through the transmission belt due to sagging of the transmission belt. In addition, the magnet can be conveniently separated from the steel belt, so as to ensure normal rotation of the transmission belt and avoid structural interference.

[0010] Further arrangement is that the transmission belt is a synchronous belt, comprising a synchronous pulley arranged on the output shaft of the second driving motor and a limiting plate arranged below the synchronous pulley for limiting the synchronous belt from being separated from the synchronous pulley and moving with the second driving motor, and a gap is formed between the synchronous belt and the limiting plate when the synchronous belt meshes with the synchronous pulley.

[0011] By adopting the above technical scheme, the limiting plate is arranged to avoid separation of the transmission belt and the synchronous pulley, to ensure stable transmission of the two, and the gap formed ensures that the transmission belt is not rubbed by the limiting plate during rotation, to ensure smooth rotation of the transmission belt and its service life.

[0012] Further arrangement is that the number of the magnetic blocks is two, and the two magnetic blocks are arranged in a radial direction and are spaced apart, the third driving assembly comprises a winding motor arranged above the magnetic blocks and a connecting rope connecting each magnetic block and a winding shaft of the winding motor.

[0013] By adopting the above technical scheme, the two magnetic blocks and the synchronous pulley form a triangular expansion for the transmission belt, to ensure smooth insertion of the steel pipe into the transmission belt, and the winding motor cooperates with the connecting rope to realize asynchronous lifting control of the two magnetic blocks, to better adapt to the shape of the drooping special-shaped transmission belt, and has better practicability. That is, when one of the magnets adsorbs the steel belt to form positioning, the structure can also control the other magnetic block to descend alone to adsorb the steel belt.

[0014] Further arrangement is that the limiting assembly comprises two limiting rods moving towards or away from each other, a clamping area formed between the two limiting rods and used for placing the steel pipe, a bidirectional screw rod rotatably arranged on the feeding frame and connected to the two limiting rods, and a fourth motor driving the bidirectional screw rod to rotate.

[0015] By adopting the above technical scheme, the fourth motor drives the bidirectional screw rod to rotate, and the two limiting rods are controlled to move towards or away from each other synchronously through the rotating bidirectional screw rod, to limit the steel pipe.

[0016] Further arrangement is that the second driving assembly comprises a screw rod rotatably arranged on the fixed seat and threadedly connected to the cutting machine, and a fifth motor driving the screw rod to rotate.

[0017] By adopting the above technical scheme, the fifth motor drives the screw rod to rotate to control the cutting machine to move reciprocally, to complete the cutting operation on the steel pipe.

[0018] Further, the movable assembly comprises a plurality of embedding slots arranged on the feeding frame and having upward openings, and a plurality of rolling balls arranged in each embedding slot, a dirt inlet is formed between each embedding slot wall and rolling ball, a dirt outlet is arranged at the lowest position of each embedding slot, and a plurality of dirt outlet channels are arranged around the embedding slot opening and are connected with the dirt inlets and the dirt outlets.

[0019] By using the above technical scheme, the steel pipe is placed above the rolling balls, and the movement of the steel pipe above the feeding frame is realized by the rolling of the rolling balls. The particulate impurities enter the dirt inlets and are discharged from the dirt outlets through the dirt outlet channels, so as to avoid the particulate impurities from entering the embedding slots and the rolling balls to cause excessive wear of the rolling balls and reduce the service life of the rolling balls.

[0020] In summary, the present application has the following advantages: the present application can reduce the production cost and the procurement cost of enterprises. BRIEF DESCRIPTION OF DRAWINGS
