Description

Technical Field

[0001] The invention belongs to the technical field of mesh end trimming devices and trimming methods, and in particular relates to a double-sided horizontal wire mesh end trimming device and a method for trimming the mesh end using the device. Background Art

[0002] Due to the limitations of welding equipment and welding process, the mesh welded by the welder has a certain length of end on the outside of the outermost longitudinal wire. When welding is completed, the end of the mesh needs to be removed. Because most of the mesh transverse wires are located above the longitudinal wires, the existing mesh end trimming device includes a cutter located above and a pad located below the cutter. Generally, the cutter is a movable blade. The connection between the longitudinal wire and the transverse wire of the mesh is placed on the pad, and the cutter cuts off the end of the transverse wire downward along the outside of the longitudinal wire. During the cutting process, because the longitudinal wire located below is cylindrical, burrs will be generated at the end of the transverse wire in the direction of the cutter's movement. The burrs generated by the cut end are located in the gap between the transverse wire and the longitudinal wire. During use, it will not cause pricking, etc.

[0003] At present, many meshes have different uses, some of which have transverse wires located above the longitudinal wires and some of which are located below the longitudinal wires. In this way, if the existing mesh end trimming device is used to trim the ends of the double-sided transverse wire mesh, the following defects will occur: when cutting the transverse wire ends located below the longitudinal wires, burrs are formed below the transverse wires. During use, the generated burrs are located on the lower surface of the mesh, resulting in low mesh quality. During transportation, storage and use, the burrs on the lower surface of the mesh will prick hands, etc. The burrs need to be manually processed by hand poking or grinding wheel, which is not only time-consuming and labor-intensive, but also increases production costs and reduces production efficiency.

[0010] Compared with the prior art, the double-sided horizontal wire mesh end trimming device and the method for trimming the mesh end using the device provided by the present invention have the following advantages: First, since it includes side fixing plates located on both sides and a lifting plate located between the two side fixing plates, fixing bolts are arranged at the rear of the two side fixing plates, a lifting mechanism fixing pin is arranged below the two side fixing plates, a lifting mechanism is fixed on the lifting mechanism fixing pin, a top rod of the lifting mechanism is connected to the lifting plate, the lifting mechanism is controlled by a control mechanism, and a reset mechanism is arranged between the side fixing plates and the lifting plate; a first card slot with a front end opening is arranged in front of the side fixing plates, a second card slot corresponding to the first card slot is arranged on the lifting plate, an upper limit plate is arranged between the two side fixing plates above the first card slot, and a second card slot corresponding to the first card slot is arranged on the lifting plate A lower limit plate is arranged between the two side fixing plates below the groove, and the lower end surface of the upper limit plate is a trapezoid with a wide upper bottom and a narrow lower bottom, and the upper end surface of the lower limit plate is a trapezoid with a wide lower bottom and a narrow upper bottom. An upper cutting knife is arranged on the upper edge of the second slot behind the upper limit plate, and a lower cutting knife is arranged on the lower edge of the second slot behind the lower limit plate; a vertical guide rod is arranged between the two side fixing plates, and a vertical guide groove is arranged on the lifting plate at a position corresponding to the vertical guide rod, and the vertical guide rod is located in the vertical guide groove; the two side fixing plates are fixed to the frame bodies on both sides of the mesh by fixing bolts behind the side fixing plates, so that the outermost longitudinal wires of the mesh are located between the upper limit plate and the lower limit plate The plates are located between the upper and lower limit plates, and the outer side surface of the outermost longitudinal wire is aligned with the outer side surface of the mesh close to the upper limit plate and the lower limit plate; the mesh to be trimmed moves forward on the conveying mesh frame, and the longitudinal wire close to the outermost side of the mesh is located between the upper and lower limit plates; according to the position of the horizontal wire in the upper and lower directions of the mesh, the welding machine transmits the position information of the horizontal wire on the mesh to the control mechanism; according to the position information of this horizontal wire on the mesh, the control mechanism controls the top rod of the lifting mechanism to push up or retract; when this horizontal wire is located above the mesh, the control mechanism controls the top rod of the lifting mechanism to retract, the top rod drives the lifting plate to move downward, and the upper cutter moves downward to cut off the end of the horizontal wire located above the mesh; when this horizontal wire is located below the mesh, The control mechanism controls the top rod of the lifting mechanism to push up, and the top rod drives the lifting plate to move up, and the lower cutter moves upward to cut off the end of the horizontal wire located below the mesh; under the action of the reset mechanism, the lifting plate returns to the initial position; the cycle is repeated in sequence until all the ends of the mesh are trimmed. The distance between the upper limit plate and the lower limit plate is preferably slightly larger than the diameter of the longitudinal wire and the transverse wire, that is, the distance between the upper limit plate and the lower limit plate is preferably slightly larger than the thickness of the intersection of the transverse wire and the longitudinal wire. Regardless of whether the transverse wire is located above or below the longitudinal wire, the burrs generated by the cutting end can be squeezed between the transverse wire and the longitudinal wire, and no burrs will be generated on the surface of the mesh, and no reprocessing is required, thereby reducing production costs and labor intensity.Secondly, since the lifting mechanism is a hydraulic cylinder, vertical side reset strip grooves are arranged on the two side fixing plates, and lifting reset strip grooves are arranged at positions corresponding to the lifting plates and the side reset strip grooves, and the reset mechanism comprises an upper reset pressure plate and a lower reset pressure plate, and a reset spring is arranged between the upper reset pressure plate and the lower reset pressure plate, and the upper reset pressure plate, the lower reset pressure plate and the reset spring are inserted into the side reset strip grooves and the lifting reset strip grooves, and the two side fixing plates are fixed to the frames on both sides of the mesh by fixing bolts at the rear of the side fixing plates, so that the outermost longitudinal wire of the mesh is located between the upper limit plate and the lower limit plate, and the outer side surface of the outermost longitudinal wire is aligned with the upper limit plate and the lower limit plate close to the outer side surface of the mesh; The mesh to be trimmed moves forward on the conveying mesh frame, and the longitudinal wire close to the outermost side of the mesh is located between the upper limit plate and the lower limit plate; according to the position of the transverse wire in the up and down directions of the mesh, the welding machine transmits the position information of the transverse wire on the mesh to the control mechanism; according to the position information of this transverse wire on the mesh, the control mechanism controls the push rod of the hydraulic cylinder to push up or retract; when this transverse wire is located above the mesh, the control mechanism controls the push rod of the hydraulic cylinder to retract, and the push rod drives the lifting plate to move downward, and the upper cutter moves downward to cut off the end of the transverse wire located above the mesh. When the lifting plate moves downward, the upper reset plate moves downward under the pressure of the lifting plate above the lifting and reset strip groove, and the lower reset plate does not move under the restriction of the side fixed plate below the side reset strip groove. When the lifting plate is pushed up, the lower reset plate moves upward under the pressure of the lifting plate under the lifting and resetting strip groove, and the upper reset plate does not move under the restriction of the side fixed plate above the side reset strip groove. At this time, the reset spring is compressed; after the force of the hydraulic cylinder push rod is withdrawn, the reset spring quickly returns to its original state under its own elastic force, and the lifting plate returns to its initial position; this reciprocating cycle is repeated until all the ends of the mesh are trimmed, and the lifting and lowering of the push rod of the hydraulic cylinder can be easily controlled by the control mechanism. After the external force is removed, the lifting plate quickly returns to its original position, and the reset is not only accurate but also fast. Of course, the lifting mechanism can also be a servo motor and a lead screw. In this way, although the above functions can be realized, the reset speed is slow, and it cannot be used on a fast mesh fast welding production line, and the cost of the equipment is high; thirdly, since an upper pad groove is provided below the upper limit plate, an upper pad is provided in the upper pad groove, a lower pad groove is provided above the lower limit plate, and a lower pad is provided in the lower pad groove, the upper pad and the lower pad can be replaced according to the diameter of the longitudinal wire and the transverse wire of the mesh to adjust the distance between the upper pad and the lower pad, so that the distance between the upper pad and the lower pad is slightly larger than the thickness at the intersection of the transverse wire and the longitudinal wire;Fourthly, since a groove is provided below the first groove on the inner side of the side fixing plate, a retaining edge is provided above the groove, and a guide plate is provided between the groove below the retaining edge and the lifting plate, impurities such as metal shavings, paint, and dust generated when cutting the end are discharged along the guide plate and will not fall on the hydraulic cylinder to cause damage to the hydraulic cylinder or other lifting mechanisms; fifthly, since the cross section of the guide plate is "V"-shaped, metal shavings, paint, and dust are prevented from deviating from the guide plate during the discharge process. ; BRIEF DESCRIPTION OF THE DRAWINGS
