Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, in particular to a feeding device for a seamless steel pipe peeling machine. Background Art

[0002] Seamless steel pipe is a round, square or rectangular steel material with a hollow cross section and no seams around it. Seamless steel pipe is made by perforating steel ingots or solid tubes into rough tubes, and then hot rolling, cold rolling or cold drawing. It is widely used as a pipeline for conveying fluids. Compared with solid steel materials such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. It is an economical cross-section steel material and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction. Before the solid tube is perforated to form a rough tube, the solid tube must be flattened and peeled. The equipment for peeling the solid tube generally uses a cutter to cut the rotating surface of the tube. In the prior art, when using a cutter to cut and peel the rotating surface of the solid tube, there is a lack of a conveying device that can automatically load the material. During the peeling process, the loading, feeding, fixing and unloading processes are very cumbersome, the operation is inconvenient, and the processing efficiency is low.

[0003] According to a feeding device for a seamless steel pipe peeling machine with publication number CN214922648U, it includes a left cylinder, a left linear guide pair, a transfer plate, a cantilever pin, a right linear guide pair, a right cylinder, a right slide, a left slide, a base, a left cylinder mounting seat, a left mounting frame, a rear cover plate, a right cylinder mounting seat, a right mounting frame, a front cover plate, a left clamp, a left floating joint, a left rack, a right floating joint, a gear, a right clamp and a right rack.

[0004] With respect to the above-mentioned related schemes, the workpiece is clamped by the left and right jaws, and the positions of the left and right jaws are adjusted to adapt to the clamping of workpieces of different specifications. However, since the angle of the "V"-shaped groove on the side of the left and right jaws is fixed, when encountering larger workpieces, it is difficult for the left and right jaws to achieve stable clamping of larger workpieces, thereby making the feeding process of the workpiece relatively unstable. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a feeding device for a seamless steel pipe peeling machine to solve the technical problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device for a seamless steel pipe peeling machine, comprising a slide seat, a bracket, a linear guide pair and a cylinder, an outer frame is arranged at the bottom end of the slide seat, an adjusting mechanism is arranged inside the outer frame, the adjusting mechanism comprises an electric push rod, a push block, a rack, a first support shaft, a second support shaft and a gear set, the rack is movably connected to the inside of the outer frame, the push block is welded to the bottom end of one side of the rack, the electric push rod is installed between the push block and the outer frame, the inside of the outer frame is rotatably connected to the first support shaft, the inside of the outer frame is located below the first support shaft and is rotatably connected to the second support shaft, the outer surfaces of the first support shaft and the second support shaft are sleeved with a gear set, the outer surfaces of the first support shaft and the second support shaft are both sleeved with a clamping claw seat, and a clamping claw is arranged on one side of the clamping claw seat.

[0007] Preferably, both ends of the electric push rod are connected to the outer frame and the push block by screws, and the gear set is meshingly connected to the rack.

[0008] Preferably, the clamping jaw seat and the clamping jaw are symmetrically arranged about the central axis between the first supporting shaft and the second supporting shaft, and the clamping jaw seat is arranged as an inverted "U"-shaped structure.

[0009] Preferably, both ends of the rack are welded with guide blocks, both ends of the inner part of the outer frame are provided with guide grooves, and the rack and the outer frame form a sliding structure through the guide blocks and the guide grooves.

[0010] Preferably, a plug-in slot is provided on one side of the clamping jaw seat, a plug-in plate is welded to one side of the clamping jaw, and the clamping jaw and the clamping jaw seat form a clamping structure through the plug-in slot and the plug-in plate.

[0011] Preferably, one end of the clamping jaw seat is provided with a mounting mechanism extending to the interior of the plug-in board, and the mounting mechanism is composed of a push-pull rod, a mounting plate, a mounting groove and a return spring.

[0012] Preferably, the push-pull rod is movably connected inside the clamping claw seat, the mounting plate is welded to one end of the push-pull rod, the return spring is welded between the mounting plate and the clamping claw seat, and the mounting groove is opened at one end of the plug-in plate.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] 1. The existing feeding device of the seamless steel pipe peeling machine clamps the workpiece by means of a clamping claw. However, due to the fixed angle of the "V"-shaped slot, it is difficult to achieve stable clamping of workpieces of larger sizes, thereby making the feeding process of the workpiece relatively unstable. The utility model is provided with an adjustment mechanism. During the operation and extension of the electric push rod, the rack can be pushed by the push block to slide along the guide groove. At the same time, due to the meshing connection between the gear set and the rack, the gear set can be rotated, so that the two symmetrically arranged clamping claws can be deflected with the first support shaft and the second support shaft as the axis, respectively, so that the angle of the clamping claw can be quickly adjusted, so that it can be suitable for stable clamping of workpieces of various sizes, thereby making the feeding process of the workpiece relatively stable.

[0015] 2. After long-term use, the jaws of the existing feeding device for seamless steel pipe peeling machines are prone to damage, which can easily affect the stable clamping and feeding of the workpiece. The utility model is provided with a mounting mechanism, a plug-in plate and a plug-in slot. Since the jaws and the jaw seat are clamped by the plug-in plate and the plug-in slot, and the plug-in plate and the plug-in slot are clamped by the mounting plate and the mounting slot, the mounting plate can be detached from the mounting slot by pulling the push-pull rod toward one end. At this time, the plug-in plate can be detached from the plug-in slot by pulling the jaws toward one end, thereby facilitating the disassembly and replacement of the damaged jaws, thereby preventing the stable clamping and feeding of the workpiece from being affected.
