Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the drawings and detailed description, in which like-named or-numbered components represent the same structure and are for illustrative purposes only, and in which the coordinate system labeled in the drawings is used to simplify the relative positional description and to indicate the relationship between the drawings.
Fig. 1 is a schematic overall structure of an embodiment of the present invention, which includes a winding mechanism 1, a feeding mechanism 2, and a receiving mechanism 3. The winding working plane 11 is a working plane of a winding mechanism; the guide groove 21 of the feeding mechanism is arranged in the winding working plane 11 of the winding mechanism 1 and points to the winding mechanism 1; behind the guide groove 21, three pairs of conveying rollers 22 are provided in the feeding direction of the guide groove, each pair of conveying rollers 22 including a fixed shaft roller 221 and a pinch roller 222.
The metal wire to be processed is typically wound on a wire reel to facilitate logistics transportation and storage. When the equipment works, the wire reel rotates under the drive of the feeder, and the wire is fed out; the wire moves along the guide groove 21 of the feeding mechanism 2, sequentially passes through three pairs of conveying rollers 22, passes out from the outlet of the guide groove 21 and enters the winding mechanism 2. The fixed shaft roller of the conveying roller 22 is driven by a motor or other power to rotate at a set linear speed, the rotating shaft of the compacting roller 222 is fixed on a base which is controlled by a hydraulic mechanism to stretch along the X direction, and the compacting of the metal wire is realized by the hydraulic mechanism. Under the action of the pressing force of the hydraulic mechanism, the wire rod is pressed between the fixed shaft roller 221 and the pressing roller 222, and under the action of static friction force of the roller surface, the fixed shaft roller drives the wire rod to advance. Three pairs of conveying rollers 22 arranged along the direction of the guide groove 21 act together, the wire rod is driven to advance at a set speed, and meanwhile straightening of the wire rod is achieved, so that the wire rod which is wound on the reel for a long time and is in a bending state reaches required straightness after passing through the conveying rollers 22 and the guide groove 21 and before entering the ring winding mechanism, the deformation of a blank caused by substandard straightness of the wire rod is reduced, and the yield is guaranteed.
Fig. 2 is a schematic view of a winding mechanism according to an embodiment of the present invention, and fig. 3 is a schematic view of a winding mechanism perpendicular to a winding working plane direction according to an embodiment of the present invention, where the winding mechanism 1 includes a bending assembly 12, a guiding assembly 13 and a cutting assembly 14 disposed in the winding working plane 11, and the bending assembly includes a supporting shaft 121, a bending press wheel 122 and a top bending wheel 123. The supporting shaft 121, the bending press wheel 122 and the top bending wheel 123 can rotate freely around the respective rotation axes, and the ring winding working plane 11 is respectively provided with a ring winding guide groove along the circumference of the cylindrical surface, that is, the supporting shaft 121 is provided with a supporting guide groove 126, the bending press wheel is provided with a pressing guide groove 122, and the top bending wheel 123 is provided with a top bending guide groove 125. The guiding component 13 is a ring-dividing piece with a wedge-shaped cross section, which is arranged below the top bending mechanism, and the wedge-shaped tip side of the ring-dividing piece points to one side of the top bending wheel 123.
The wire straightened by the feeding mechanism 2 passes through the guide groove 21 and then enters the supporting guide groove 126 and the compacting guide groove 124, and as the bending pinch roller 122 and the supporting shaft 121 are respectively positioned at two sides of the wire in the winding working plane 11, the wire is reliably limited in the winding working plane 11, and meanwhile, the movement of the wire in the winding working plane 11 is limited, and in the process that the wire is pushed to advance, the wire continuously enters the top bending guide groove 125 positioned in the winding working plane 11 and arranged in the circumferential direction of the top bending wheel 123 with a certain height difference with the bending pinch roller 122. Under the action of the top bending wheel 123, the wire is plastically deformed, bent in an arc shape in the winding working plane 11, and the bent wire passes through the cutting assembly 14 to return to the top surface of the bending pressing wheel 122 above the supporting shaft 121 along with the operation of the feeding mechanism 2, so that a first spiral wire is formed. The device continues to run, the spiral wire continuously grows around the supporting shaft 121 to the outer side of the winding working plane 11, and after reaching a certain spiral height, the cutting mechanism 14 acts to cut the wire to form a spiral piston ring blank. In the process of the spiral wire growth, more than one circle of wire is shunted to the outer side of the cutting mechanism through the wedge-shaped tips of the material dividing sheets of the guide assembly 14, so that the wire is prevented from repeatedly entering the cutting mechanism. Due to the existence of the supporting guide groove 126, the pressing guide groove 124 and the top bending guide groove 125, the wire can be reliably limited in the working plane of the winding ring, so that the twisting deformation of the wire in the top bending process is avoided, and the yield is further improved.
The cutting assembly 14 is disposed below the supporting shaft 121, fig. 4 is a cross-sectional view of the cutting assembly 14 in the direction A-A in fig. 2, the cutting assembly 14 includes a cutting seat 141 and a cutting knife 142, the cutting seat 141 is provided with a piston ring channel 149 in the winding working plane 11, and a cutter groove 148 perpendicular to the winding working plane is provided with the cutting knife 142. The cutter is secured to a hydraulic cylinder piston rod or other controllable telescopic member for controlling movement of the cutter 142 within the cutter slot 148, and the piston ring billet wire extending from the piston ring channel 149 is cut at the outlet by the shearing action of the cutter 142 and the cutting seat.
The bending component 12, the guiding component 13 and the cutting component 14 of the ring winding mechanism 1 are designed with adjustable positions, and specifically, the bending pinch roller 122 is arranged on a linear guide rail parallel to the ring winding working plane 11 and parallel to the guide groove 21; the top bending wheel 123 and the guide assembly 13 are respectively arranged on two groups of mutually orthogonal linear guide rails, and the guide rails forming the two groups of mutually orthogonal linear guide rail groups are parallel to the ring-winding working plane; the severing assembly 13 is arranged on a linear guide parallel to the work plane 11 of the winding. The linear guide rails are provided with screw rod screw pairs in an auxiliary mode, and a handle and an index plate for controlling and indicating the number of turns of the screw rod, so that the positions of the bending component 12, the guiding component 13 and the cutting component 14 in the ring winding working plane 11 are distributed in a nearly circular mode with a certain specific size through rotating the handle, the ring winding mechanism 1 is controlled to produce spiral piston ring blanks with the specific size, and the diameters of the piston ring blanks in actual production can be adjusted within a range of 90mm-160 mm.
Fig. 5 and 6 are perspective views of two different views of the material receiving mechanism, where the material receiving mechanism 3 includes a material stirring assembly 31, a material storage assembly 32 and a material receiving base 34. The material stirring assembly 31 is arranged on an orthogonal guide rail set formed by a lifting guide rail 312 and a material stirring guide rail 311, the material stirring assembly is provided with a U-shaped notch for avoiding the cutting assembly 13, and the material stirring guide rail 311 and the supporting shaft 121 are arranged in parallel.

After the set number of storage materials in the first storage device 321 is reached, the linear guide rail moves to move the second storage component 322 on the storage component 32 to the material receiving position, so as to continuously complete the storage work of the second storage component 322.
