Description

Technical Field

[0001] The present application relates to the field of lean tube production, and in particular to a cutting device for lean tube production. Background Art

[0002] At present, lean pipes are composite pipes made of steel alloy and polymer plastics. Lean pipes are welded steel pipes that are surface treated with high-quality steel pipes and covered with plastic resin coatings. The outer surface of the steel pipe adopts a special plastic layer bonded with thermoplastics, and the inner surface is covered with an anti-corrosion layer. In order to meet environmental protection requirements, no adhesive is used between the metal layer and the plastic layer. Lean pipes have the characteristics of wear resistance, easy assembly, rust prevention, pollution-free, and reusability. They are ideal substitutes for stainless steel products.

[0003] The tools needed in the existing lean tube production process include cutting equipment and fastening equipment. A grinding wheel cutter is usually used in the cutting equipment to cut the lean tube. The grinding wheel cutter is used to cut the lean tube to a suitable length to facilitate the subsequent assembly of the lean tube.

[0004] The above-mentioned prior art solutions have the following defects: there are many burrs on the fracture of the lean tube after cutting. When assembling the lean tube products, the burrs are easy to cause scratches, the safety is low, and grinding parts are needed to grind the burrs. Frequent use of grinding parts causes the grinding parts to wear faster, and the grinding parts need to be replaced frequently. Utility Model Content

[0008] By adopting the above technical solution, the output shaft of the second motor is connected to the second connecting shaft of the grinding piece, and the second motor drives the grinding piece to grind the fracture of the lean pipe after cutting. The second connecting shaft is inserted on the output shaft, and a fixed plane is formed on the second connecting shaft. The fixed plane is adapted to the output shaft. The setting of the fixed plane prevents the second connecting shaft from slipping in the process of following the rotation of the output shaft. The fixing pin passes through the output shaft and is inserted on the fixing plane of the second connecting shaft to fix the second connecting shaft to the output shaft. The limiting member is used to abut against the limiting box to fix the position of the fixing pin, thereby improving the stability of the connection between the second connecting shaft and the output shaft, so that the second connecting shaft will not loosen and detach from the output shaft due to the interference of rotation. The limiting member is provided to facilitate the disassembly and assembly of the fixing pin, thereby realizing the rapid replacement and maintenance of the second connecting shaft.

[0009] Optionally, the cutting device further comprises a limit baffle, wherein the limit baffle is fixedly connected to the inner wall of the limit box, and the limit member can abut against the limit baffle.

[0010] By adopting the above technical solution, the limit member passes through the limit box, and the rotating fixing pin makes the limit member abut against the inner wall of the limit box. The limit baffle can prevent the fixing pin from excessive rotation. When removing the fixing pin, the limit baffle can enable the limit member to quickly find the position of the hole that matches the limit member, so that the fixing pin can quickly detach from the limit box.

[0011] Optionally, the cutting device further comprises a grinding piece, wherein the grinding piece comprises a grinding wheel, and the grinding wheel is in a frustum shape, wherein an end surface of the grinding wheel having a larger area is fixedly connected to an end portion of the second connecting shaft away from the output shaft.

[0012] By adopting the above technical solution, the frustum-shaped grinding wheel can more easily fit the inner wall of the fracture after the lean tube is cut, and can grind the lean tubes of different diameters at the same time.

[0013] Optionally, the cutting equipment also includes two groups of spaced-apart pushing components, the pushing components including an electric push rod, a sliding seat, and a clamping member. A sliding groove is provided on the upper surface of the support plate, and the length direction of the sliding groove is parallel to the side wall of the support plate.

Compared with manually holding the lean tube for cutting, the pushing assembly has higher precision and higher safety.

[0015] Optionally, the clamping member includes two arc-shaped elastic clips, and the arc openings are arranged opposite to each other.

[0016] By adopting the above technical solution, the curved clip can make the clamp adapt to lean tubes with different diameters without damaging the outer wall of the lean tube.

[0017] Optionally, the ends of the clamping member are processed to form an arc, and the arc openings are arranged opposite to each other.

[0018] By adopting the above technical solution, the curvature of the end of the clamping piece makes the clamping piece opposite to the clamping piece form a flared shape, and the flared shape enables the clamping piece to clamp the lean tube more quickly.

[0019] Optionally, the cutting equipment also includes a cutting assembly, which includes a cutting seat, a first motor, a bevel gear, a first connecting shaft and a cutting sand disc. The cutting seat is fixedly connected to the upper surface of the support plate, the first motor is fixedly connected to the outer wall of the cutting seat, the bevel gear is arranged in the cutting seat, the rotating shaft of the first motor is connected to the first connecting shaft through the engagement of the bevel gear, one end of the first connecting shaft passes through the cutting seat and is fixedly connected to the bevel gear, the cutting sand disc is detachably arranged at the end of the first connecting shaft away from the cutting seat, and the cutting sand disc is parallel to the side wall of the support plate.

[0020] By adopting the above technical solution, the cutting assembly uses the first motor to drive the cutting sand disc to rotate for cutting. The first motor drives the cutting sand disc to rotate through the bevel gear steering. The bevel gear is arranged at the cutting seat position inside the cutting seat and is suspended on the support plate to avoid the coaxial connection between the motor and the sand disc causing a large load on the suspended part of the cutting seat, thereby reducing the possibility of damage to the cutting seat.
