Definitions
- the invention relates to an improved mechanism of a machine tool in the process of processing steel rods to form a wire rod packing in the steel field, and specifically relates to a further improved structure of a gasket placement mechanism of a high-speed wire rod packing machine.
- the wire rod packing machine is a fully automatic packing device that uses steel wire or steel belt as the binding material to bundle the high-speed wire coils.
- the function of the strapping machine is to compress the loose wire coils in the axial direction and tie them firmly with steel wires or steel belts to prevent them from loosening for storage and transportation.
- Axial compression is that the compression trolley presses the pressure plate and the anti-frustration disc to compress the loose wire coil in the axial direction.
- the bundling method is symmetrical extrusion and bundling. Two compression trolleys are used from the coil. The two sides are evenly and symmetrically pressed, and then bundled.
- the strapping line can be a steel wire or a steel belt.
- the pressure plate is made of steel.
- the oppositely moving surfaces of the pressure plate are equipped with anti-frustration discs with a diameter larger than the diameter of the coil forming ring.
- the hardness of the anti-frustration disc is less than that of steel, and it can be partially or completely replaced if it is damaged after a period of use.
- the four steel wires are fed and tightened by four independent steel wire guiding mechanisms at the four diagonal corners, and the tightening and cutting actions are completed by the four packing heads.
- the four sets of packing heads are evenly distributed on the four diagonal corners of the pressing plate on the pressing trolley, and they are all 45° with the horizontal line.
- Each packing head is fixed on two sliding rods through special sliding bearings.
- the sliding rods are fixed on the compaction trolley.
- the packing head has two working positions, namely one feeding position (initial position) and the other closing position ( Front position).
- the exchange of the two positions is driven by a hydraulic cylinder.
- the action of the hydraulic cylinder is when the compression trolley compresses the loose coil, the wire guide mechanism feeds and tightens the wire, and then the hydraulic cylinder pushes the packing head to the center. On the coil, after the kinking and cutting actions are completed, the packing head returns to the initial position.
- the packing machine includes two ends that move back and forth in the pressing direction. Two pressure plates; the two opposing pressing surfaces of the pressure plate are fixed to a circular anti-frustration disc with a certain thickness. The pressure plate and the anti-frustration disc are provided with four wire grooves for tying steel wires at the four diagonal corners. The groove divides the anti-frustration disc into four sector-shaped plates on the upper, lower, left and right;
- a continuous push mechanism for gaskets is respectively provided at the four opposite corners of the pressure plate;
- the gaskets are metal sheets in a large number, and are pushed one by one through the passageway made by the anti-frustration disc to the position of the wire groove of the pressure plate by a continuous pushing mechanism, and the wrapping and winding direction of the gasket is consistent with the direction of the wire groove.
- This invention proposes for the first time in the field that no manual on-site operation is required. It is purely machine-borne, and a large number of gaskets are placed regularly. After the packaging is completed, there is no waste to be cleaned on the site, which is convenient and fast, and eliminates personnel drilling in high-temperature environments The danger of entering the packing machine and sticking the gasket, or the danger of workers hanging the circular cardboard under the moving C-shaped transmission hook.
- the inventor Zhang Xuesong proposed "A gasket placement mechanism and gasket structure of a high-wire coil baler” CN109795756A and “A gasket placement mechanism and a high-wire coil baler” Spacer structure "CN109969502A, the spacer is a parallelogram, or a long and narrow rectangle, adjacent spacers are connected with a hypotenuse or a long side, and are inclined at an angle to the horizontal, and the inclination direction is consistent with the direction of the groove on the pressure plate, Serrated holes or line-like depressions are provided between adjacent gaskets.
- each baler is fixed on two sliding rods through special sliding bearings, and the sliding rods are fixed on the pressure plate trolley, and the baler occupies a section of the pressure plate and the anti-frustration circle to varying degrees.
- the area and space on the disk cause a section of the outer end of the original long rectangular slot to increase in width, and the increased width dimensions are also different. It is a long rectangle and a short rectangle with an increased width at the end, which is almost one.
- a long shank has a knife handle on one side or a slotted slot on both sides.
- the purpose of the present invention is to provide a way to overcome the inconvenience and trouble of using CN109795755A technology on the existing baler.
- the structure of the baler with the baling head on one side of the pressure plate can still realize the continuous push of the gasket and still enable the gasket to be protected in a targeted manner.
- Improved device for wire rod can still realize the continuous push of the gasket and still enable the gasket to be protected in a targeted manner.
- a shim roll composed of a large number of shim is arranged at the four opposite corners of the pressure plate on one side, and is pushed horizontally one by one through the passage of the anti-frustration disc to the wire groove position of the pressure plate by a continuous pushing mechanism.
- the gasket is in the shape of a long and narrow rectangle or a parallelogram.
- the adjacent gaskets are connected by long sides or hypotenuses, and the long sides or hypotenuses are inclined at an angle with the horizontal, and the inclination direction is consistent with the direction of the line groove on the pressure plate, adjacent to each other. Serrated holes or line-like depressions are set between the gaskets;
- Packing heads with functions of tightening and cutting the strapping line are arranged along the four diagonal directions of the pressure plate.
- the packing head is pushed by the oil cylinder on the pressure plate and the anti-frustration disc and extends into the diagonal center for a certain distance, and is formed on the outside of the long rectangular wire groove.
- a right-angle notched knife handle-shaped bead is set at the position of the wire groove from the passageway of the anti-frustration disc to the pressure plate.
- the knife-shaped bead has two bead openings that are parallel to the direction of the wire groove and shifted back and forth.
- the front bead opening is located in the first gasket and At the joint of the second gasket, the back bead opening is located at the joint between the second gasket and the third gasket;
- first and second arc push rods for the first gasket and the second gasket are arranged side by side.
- the outer end portion of the first gasket is bent in an arc shape toward the wire rod side, and the connection between the outer end portion of the second gasket and the third gasket is torn apart.
- a right-angle notched knife-shaped bead is set at the position of the anti-frustration disc on one side of the pressure plate of the packing head to the line groove of the pressure plate, which is in the shape of a knife plate and a knife handle, and the knife-shaped bead has two and
- the line groove direction is parallel to the front and back offset bead opening, the front bead opening is located at the joint between the first gasket and the second gasket, the rear bead opening is located at the joint between the second gasket and the third gasket, the front and rear bead openings
- the staggered junction of the ports is located at 1/2 to 2/3 from the center to the outer end in the length direction of the first gasket.
- This solution changed the shape of the linear bead that was originally located on one side of the pressure plate of the packing head along the line between the first gasket and the second gasket that was first sent out, and changed to a stepped, right-angled notch knife-shaped bead structure, two The bead openings which are shifted back and forth parallel to the direction of the wire groove are respectively pressed against the joint between the first gasket and the second gasket and the joint between the second gasket and the third gasket. It can be seen that the distance between the front bead opening and the rear bead opening is exactly equal to the width of the second gasket, and of course it is also equal to the width of all other gaskets.
- the notch blade exposes the 1/2 of the second gasket from the center to the outer end. Up to 2/3 of the area, while also covering the remaining area of the second gasket. The rear part of the rear bead opening of the right-angle notch blade-shaped bead is completely covered with the third gasket and the rear gasket.
- the right-angle notch described here is not strictly a right-angle, as long as it achieves the effect of the technical solution, avoids the contact and collision of the baling head advancing, and forms a shape similar to steps and missing corners, it is within the limited scope of the present invention.
- the two openings of the first gasket and the second gasket are arranged side by side in the direction and position where the packing head pushes toward the diagonal center of the pressure plate.
- the two openings of the first gasket and the second gasket are bent in the pushing direction.
- the outer end part of the first gasket can be freely pushed by the first arc push rod to bend into an arc shape toward the side of the wire rod, so that the first gasket wraps the outside of the wire rod first.
- the technology of CN109795755A utilizes the first gasket and the second gasket to be torn off at one time when the bundled steel wire is tightened, and the first gasket covers the inside and outside of the wire rod while the bundled steel wire is tightened.
- the back bead opening is located at the joint between the second gasket and the third gasket, the second arc push rod pushes the completely exposed outer end of the second gasket to bend upwards, and the whole piece of the third gasket is cut by a right-angled knife handle
- the shaped bead is pressed to force the connection between the upwardly bent part of the second gasket and the outer end part of the third gasket to be torn apart.
- the first gasket is made to wrap the outside of the wire rod first.
- the packing and binding steel wire is tightened, the first gasket and the second gasket that are naturally torn off are still If less than half of the connection is connected, the first gasket covers the inside of the wire rod.
- the gasket continues to be pushed to the wire groove, the original third gasket becomes the new second gasket, and the original second gasket becomes the new first gasket.
- the gasket has torn off the outer part of the connection, which just lays the foundation for binding the new first gasket.
- the packing head advances, let the new first gasket bend toward the wire rod and wrap the outside of the wire rod first;
- the completely exposed outer end part of the new second gasket is torn apart from the new third gasket; the four bundled steel wires are pierced from the outside to the inside at the four diagonal corners and tightened while tearing the new first gasket and the new third gasket.
- the bundled steel wire wraps the new first gasket on the inner and outer sides of the wire rod, and the bundled steel wire is twisted and cut again, and the cycle operation is repeated.
- the patented technology of CN109795755A coupled with the technology of the present invention, only needs to be adjusted to the shape of one or two handles of the long handle of the existing baling head on one side of the platen.
- the size of the wire groove of the side shovel-shaped notch is slightly modified, and two arc push rods are placed on the packing head at the same time, and a new function can be added to the traditional wire rod packing machine: the function of automatically placing the wire rod protection gasket. , Can easily change the operation method of placing protective gaskets in this industry field, and realize the mechanization and automation of the placement of protective gaskets for wire rods.
- the present invention realizes that the entire set of baler equipment currently in use does not need to be modified, and the implementation of the CN109795755A technical solution can be simple and feasible only by adopting the above two measures, the implementation period is shorter, the cost is less, and the realization of mat
- the chip placement is mechanized and automated, and the original patent is maintained to reduce the area of the gasket used in the current industry, reduce the material used, place it in a targeted position, and have the advantages of good pad placement.
- the packing head device is arranged at the four opposite corners of the pressure plate. If strictly required, it should have a symmetrical structure on the left and right sides, and the upper and lower sides. However, in order to reduce the cost and simplify the production, the packing machine manufacturer will complete the four packing heads.
- the same structure is arranged in a clockwise or counterclockwise direction. The result of this structure is that the increased width and/or position of the outer end of the slot at the 45° diagonal of the pressure plate is inconsistent, and some are protruding.
- the width of the slot cavity is at the outcropping of the gasket, some are on the opposite side of the outcrop, and some are on both sides, and the protruding width is different.
- Adopting this technical solution can be "take all” and applicable, because “the front bead opening is located at the joint between the first gasket and the second gasket, and the rear bead opening is located at the joint between the second gasket and the third gasket. ”, the bead opening is only for the joint between the gasket and the gasket, and has nothing to do with the increased width of the slot end. If the protruding width of the groove cavity is at the exposed head of the gasket, it is only at the gasket’s exposed head.
- the length of the blade of the blade-shaped bead blade that is, the length from the staggered junction of the front and back bead openings to the apex of the blade of the blade is equal to 1/3 to 2/3 of the length of the shim.
- the first arc-shaped push rod is higher than the second arc-shaped push rod.
- the widths of the first arc-shaped push rod and the second arc-shaped push rod are less than 1/2 of the width of the first gasket and the second gasket, and are installed in the second half of the width of the gasket in the pushing direction, avoiding The location of the bundled steel wire.
