Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a precision copper tube rolling core rod pinch roller. Background Art

[0002] The copper tube rolling mandrel pinch roller is an important equipment component used in the copper tube rolling process. Its main function is to ensure that the copper tube maintains a stable and precise shape during the rolling process. Through the clamping force, it can ensure the stability of the copper tube and prevent deviation and deformation during the rolling process. At the same time, the transmission feed ensures that the copper tube is evenly and stably fed into the rolling mill to ensure the accuracy of the product.

[0003] At present, most of the existing precision copper tube rolling core rod pinch rollers are connected to the frame or support structure at both ends of the pinch rollers and connected to the drive device. When the drive device is in operation, the pinch rollers rotate. However, in the event of a failure, it is inconvenient to disassemble and assemble the pinch rollers, which has certain defects. At the same time, the traditional pinch rollers are made of all-iron materials. Due to friction resistance during rotation, iron powder will be generated, which brings great quality problems to copper processing production. Although the pinch rollers with an iron outer layer and polyurethane material rubber coating eliminate iron powder during use, the middle groove has cracked after being squeezed, which has the problem of short service life. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a precision copper tube rolling core rod pinch roller, which has the advantages of being able to quickly disassemble and assemble and improving the service life of the pinch roller. It solves the current problems of complicated disassembly and assembly of the pinch roller, the easy generation of iron powder by pure iron pinch rollers, and the easy cracking and short service life of pinch rollers with outer corner wraps.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision copper tube rolling core rod pinching roller, comprising a conveying assembly and a clamping assembly, the conveying assembly comprising a pinching roller, a core rod fixed on the pinching roller, and a rubber-coated polyurethane fixed on the side of the core rod, and a baffle fixed on the core rod, a fixing screw threaded on the baffle, and a connecting button provided on the baffle, and a rotating ring movably hinged on the side of the connecting button, the conveying assembly comprises two pinching rollers, and a core rod passing through both ends is fixed in the two pinching rollers, and the core rod is made of iron material into a stepped groove type, which is beneficial to improving the adsorption of the rubber-coated polyurethane, and baffles are installed on both sides coated with the rubber-coated polyurethane, and the baffles are fixed to the core rod by fixing screws. By coating with the rubber-coated polyurethane, the iron powder generated by the rotation resistance of the core rod when the pinch roller rotates is reduced.

[0008] The clamping assembly includes a clamping side plate installed on the clamping roller, a limiting slide groove runs through the clamping side plate, and the rotating ring is slidably connected to the limiting slide groove. At the same time, a docking side plate is clamped on the clamping side plate, and both ends of the clamping side plate are provided with limiting slide grooves running through the outer side of the clamping side plate. At the same time, both ends of the clamping side plate are plugged with docking side plates, and the docking side plates are used to seal the limiting slide groove. At the same time, the inner side of the docking side plate is semicircular, and the diameter is consistent with the diameter of the side of the rotating ring, which improves the fit of the rotating ring and prevents the rotating ring from escaping from the limiting slide groove when sliding left and right.

[0009] When the precision copper tube rolling core rod clamping roller is assembled and used, two sets of clamping assemblies are provided, and the clamping roller is fixed on the side of the core rod, and the two sides of the core rod are coated with rubber-coated polyurethane, and a baffle is installed on the side coated with rubber-coated polyurethane, and the baffle and the core rod are locked and fixed by fixing screws, and then a rotating ring is installed on the connecting button at both ends of the clamping roller, and the rotating ring is installed in the limiting slide groove, and the groove is slidably connected to the side of the convex strip, and then a docking side plate is installed at both ends of the clamping side plate, and then the docking rod is pressed to make the spring button retract into the socket button, and push the docking rod so that the socket button is slidably connected in the docking slide groove, and the sliding button is slidably connected in the limiting slide groove, so that the docking side plate is completely fixed on the side of the clamping side plate, thereby closing the limiting slide groove, and at the same time, the output end of the spring rod pushes the side of the rotating ring, so that the clamping roller is clamped toward the middle, and during the rotation process, the object can be clamped and transmitted.

[0010] As a further improvement of the above solution, a groove is provided on the side of the rotating ring, and convex strips are provided in the limiting sliding groove and the docking side plate, and the groove is slidably connected to the convex strips.

[0011] Through the above technical solution, when the rotating ring slides in the limiting slide groove, it slides on the side of the convex strip through the groove, thereby improving the stability of the movement of the rotating ring and preventing the rotating ring from escaping from the limiting slide groove.

[0012] As a further improvement of the above solution, a spring rod is fixed to one end of the docking side plate, and one end of the spring rod is fitted on the side of the rotating ring.

[0013] Through the above technical solution, the output end of the spring rod has a pushing force, which makes the rotating ring slide in the limiting slide groove, so that the two pinch rollers move closer to the middle, which has the effect of clamping and conveying the objects.

[0014] As a further improvement of the above-mentioned solution, a docking groove is provided on the clamping side plate, a limiting plate is fixed in the docking groove, a socket hole is provided at one end of the limiting plate, a docking rod is movably socketed in the socket hole, a socket button is fixed at one end of the docking rod, the socket button is slidably connected in the docking groove, and fits into the bottom of the limiting plate.

[0015] Through the above technical solution, a sliding button is installed in the middle of the docking rod, and a sleeve button is installed at the bottom end of the docking rod. When the docking rod is pressed down, the spring button is retracted into the sleeve button. At this time, the sleeve button is aligned with the docking slot, and the sliding button is aligned with the limiting slot. At this time, the docking rod is pushed so that the sleeve button is attached to the bottom of the limiting plate, and the sliding button is attached to the bottom of the limiting plate, thereby realizing the function of fixing the docking side plate and the clamping side plate after insertion.

[0016] As a further improvement of the above solution, a spring button is movably sleeved in the sleeve button, and the spring button fits in the docking slot.

[0017] Through the above technical solution, when the sliding button is in the calibration hole and the sleeve button is inside the sleeve hole, the spring button pushes the docking rod to drive the sliding button and the sleeve button out of the corresponding holes, so that the docking side plate can be separated from the clamping side plate.

[0018] As a further improvement of the above-mentioned solution, a limiting groove is provided at one end of the docking side plate, a limiting plate is fixed in the limiting groove, a calibration hole is provided at one end of the limiting plate, and a sliding button is fixed on the side of the docking rod, the sliding button is slidably connected in the limiting groove, and fits against the bottom of the limiting plate.

[0019] Through the above technical solution, the diameter of the sliding button matches the diameter of the calibration hole. When the sliding button is in the calibration hole, the docking rod can drive the sliding button to disengage from the calibration hole. When the sliding button is slidably connected in the limiting slide groove, the top of the sliding button is attached to the bottom of the limiting plate to achieve snap-fitting and fixing, thereby performing a snap-fitting and fixing function between the clamping side plate and the docking side plate.

[0022] 2. The precision copper tube rolling core rod pinch roller has limit slide grooves opened at both ends of the clamping side plate. The pinch roller is installed in the limit slide groove through the rotating rings on the connecting buttons at both ends. The docking side plates are installed by plugging and installing at both ends of the clamping side plate. The docking side plates seal the limit slide groove. At the same time, by pressing and sliding the docking rod left and right, the clamping side plate and the docking side plate can be fully fixed and separated, which effectively improves the convenience of disassembly and assembly.
