Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, wherein components with the same name or the same reference number represent the same structure and are only used for illustrative purposes, and the coordinate systems shown in the drawings in the description are only used for simplifying the relative position description and indicating the relationship between the drawings in the description.
Fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, which includes a ring winding mechanism 1, a feeding mechanism 2, and a receiving mechanism 3. The winding working plane 11 is a working plane of the winding mechanism; the guide groove 21 of the feeding mechanism is arranged in the ring winding working plane 11 of the ring winding mechanism 1 and points to the ring winding mechanism 1; behind the guide groove 21, three pairs of conveying rollers 22 are provided along the feeding direction of the guide groove, and each pair of conveying rollers 22 includes a fixed-axis roller 221 and a pressure roller 222.
The metal wire to be processed is usually wound on a wire reel for convenient logistics transport and storage. When the equipment works, the wire reel is driven by the feeding machine to rotate, and the wire is sent out; the wire rod moves along the guide groove 21 of the feeding mechanism 2, sequentially passes through three pairs of conveying rollers 22, penetrates out of an outlet of the guide groove 21 and enters the ring winding mechanism 2. The fixed axis roller of the feeding roller 22 is driven by a motor or other power to rotate at a set linear velocity, and the rotating shaft of the pressing roller 222 is fixed on a base which is controlled by a hydraulic mechanism to stretch and retract along the X direction, so that the metal wire is pressed by the hydraulic mechanism. Under the pressing force of the hydraulic mechanism, the wire is pressed between the fixed-axis roller 221 and the pressing roller 222, and under the static friction force of the roller surface, the fixed-axis roller drives the wire to advance. The three pairs of conveying rollers 22 arranged along the direction of the guide groove 21 act together to drive the wire to move forward at a set speed and simultaneously realize the straightening of the wire, so that the wire which is wound on the reel for a long time and is in a bending state passes through the conveying rollers 22 and the guide groove 21 and then enters the ring winding mechanism to reach the required straightness, thereby reducing the blank deformation caused by the unqualified straightness of the wire and ensuring the yield.
Fig. 2 is a schematic view of a looping mechanism according to an embodiment of the present invention, and fig. 3 is a schematic view of a looping mechanism according to an embodiment of the present invention, which is perpendicular to a looping working plane, where the looping mechanism 1 includes a bending component 12, a guiding component 13, and a cutting component 14, which are disposed in a looping working plane 11, and the bending component includes a supporting shaft 121, a bending pressure wheel 122, and a top bending wheel 123. The supporting shaft 121, the bending pressing wheel 122 and the top bending wheel 123 can freely rotate around respective rotation axes, and winding guide grooves are respectively arranged in the winding working plane 11 along the circumference of the cylindrical surface, namely, the supporting shaft 121 is provided with a supporting guide groove 126, the bending pressing 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 guide component 13 is a ring-dividing piece with a wedge-shaped 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 penetrates out of the guide groove 21 and enters the supporting guide groove 126 and the pressing guide groove 124, because 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, 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 which is positioned in the winding working plane 11 and is 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 and is arcuately bent in the working plane 11 of the winding ring, and along with the operation of the feeding mechanism 2, the bent wire passes through the cutting assembly 14 and returns to the top surface of the bending press wheel 122 above the supporting shaft 121, so that a first circle of spiral wire is formed. When the apparatus continues to operate, the spiral wire rod grows around the support shaft 121 to the outside of the ring winding work plane 11, and after reaching a certain spiral height, the cutting mechanism 14 operates to cut the wire rod, so as to form a spiral piston ring blank. In the growth process of the spiral wire, more than one circle of wire is shunted to the outer side of the cutting mechanism through the wedge-shaped tip of the distributing piece of the guide assembly 14, and 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, the twisting deformation of the wire in the top bending process is avoided, and the yield is further improved.

The cutting knife is fixed on a piston rod of a hydraulic cylinder or other controllable telescopic components to control the cutting knife 142 to move in the cutting knife groove 148, and the piston ring blank wire extending out of the piston ring channel 149 is cut off at the outlet through the shearing action of the cutting knife 142 and the cutting seat.
The bending assembly 12, the guiding assembly 13 and the cutting assembly 14 of the looping mechanism 1 are designed to be adjustable in position, and specifically, the bending pressing wheel 122 is arranged on a linear guide rail which is parallel to the looping 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 rails are parallel to the working plane of the winding ring; the cutting assembly 13 is arranged on a linear guide parallel to the working plane 11 of the winding ring. The linear guide rails are provided with a screw pair of a screw rod 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 assembly 12, the guide assembly 13 and the cutting assembly 14 in the winding working plane 11 are distributed in a near-circular shape with a certain specific size by rotating the handle, the winding mechanism 1 is controlled to produce a spiral piston ring blank with the specific size, and the diameter of the piston ring blank can be adjusted within the range of 90-160 mm in actual production.
Fig. 5 and 6 are perspective views of the receiving mechanism from two different viewing angles, and the receiving mechanism 3 includes a material poking assembly 31, a material storage assembly 32 and a receiving base 34. The material shifting assembly 31 is arranged on an orthogonal guide rail group consisting of a lifting guide rail 312 and a material shifting guide rail 311, the material shifting assembly is provided with a U-shaped notch which is used for avoiding the cutting assembly 13, and the material shifting guide rail 311 is arranged in parallel with the supporting shaft 121.

After the cutting assembly 14 performs the cutting operation, the material-pulling assembly 31 rises to the high point of the lifting guide rail 312, moves from one end of the material-pulling guide rail 311 near the ring-surrounding working plane 11 to the other end of the material-pulling guide rail 312, and pulls the cut spiral blanks into the first storage device 321. After the set storage quantity is reached in the first storage device 321, the linear guide moves the second storage component 322 on the storage component 32 to the material receiving position, and the storage work of the second storage component 322 is continuously completed.
