[0002] Wire mesh is widely used in petroleum, hardware, chemical industry, construction, machinery and other fields. According to the production process of wire mesh, it can be divided into weaving type, spot welding type, cutting and pulling type, stamping type, etc. Among them, spot welding type production process is the most common. Before spot welding, the wires should be arranged in the wire frame. After spot welding, the excess ends of the wires should be removed. In order to avoid the formation of sharp corners at the cutting part, the wire frame is usually placed at an angle during cutting, so that the cutting surface and the wire frame form a continuous inclined plane. In the current wire cutting process, it is difficult to control the position and inclination angle of the wire frame, and the cutting accuracy cannot be guaranteed. Summary of the invention

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] Example 1

[0024] See attached Figure 1-5 A manual positioning head cutting machine includes a cutter and a positioning mechanism, the positioning mechanism includes a cutter seat 1 and a positioning seat 2, a wire mesh piece 4 to be cut is placed on the cutter seat 1 and the positioning seat 2, the cutter seat and the positioning seat are tilted so that the wire mesh piece 4 placed on the cutter seat 1 and the positioning seat 2 has an inclination angle; at least two hanging columns 3 are arranged on the cutter seat 1, at least two of the hanging columns 3 are supported on the iron wire forming the wire mesh piece, so as to limit the displacement of the wire mesh piece 4.

[0025] Furthermore, a side of the wire mesh sheet 4 close to the end to be cut is overlapped on the cutter seat 1 , and a side of the wire mesh sheet far from the end to be cut is overlapped on the positioning seat 2 .

[0026] Based on the above technical solution, it should be noted that a row of wires arranged in parallel and with flush ends are cut simultaneously by one action of the cutter. In the wire mesh, the four wires forming the edge of the wire mesh are frames. In the two opposite frames parallel to the row of ends to be cut (parallel to the length direction of the cutter), the frame close to the row of ends to be cut is the head end frame of the wire mesh, the frame away from the row of ends to be cut is the end frame of the wire mesh, and the two opposite frames perpendicular to the head end frame and the end frame are the left side frame and the right side frame. According to the above direction definition, when the wire mesh is cut, the head end is overlapped on the cutter seat 1, and the end end is overlapped on the positioning seat 2. The switch transmits a signal to the drive device of the cutter to drive the cutter to perform the cutting action. A cutter is arranged above the cutter seat, and the cutter cuts the wire ends from top to bottom. The cutter can be driven by pneumatic or hydraulic as a driving force or other methods known to the public.

[0027] Furthermore, the angle formed by the wire mesh sheet placed on the cutter seat 1 and the positioning seat 2 is 5°. After the wire is spot welded, the ends to be cut on both sides are formed. When cutting the inner end, the end of the wire mesh sheet tilts downward by 5°, and when cutting the outer end, the end of the wire mesh sheet tilts upward by 5°. Figure 2 , Figure 3 Shown is a schematic diagram of cutting the inner end.

[0028] In order to facilitate the material hanging column 3 to adapt to different positions, at least two of the material hanging columns 3 are detachably connected to the cutter seat 1 respectively.

[0029] In order to adjust the contact position between the hanging column 3 and the wire mesh wire, the cutter seat 1 is provided with a long strip connecting hole, and the hanging column is assembled into the long strip connecting hole by bolts.

[0030] Furthermore, at least two of the hanging posts 3 abut against two sides of any grid of the wire mesh, and each hanging post is in contact with two vertical wires forming the grid.

[0031] Based on the above technical solution, the arbitrary grid can be a grid of the smallest specification, or it can be a large grid formed by small grids. Two hanging posts are pressed against the left and right sides of the grid to prevent the wire mesh from moving left and right. When the end of the wire mesh is tilted downward, the hanging post 3 presses against the wire at the head end of the grid to prevent the end of the wire mesh from sliding downward. When the end of the wire mesh is tilted upward, the hanging post 3 presses against the wire at the end of the grid to prevent the head end of the wire mesh from sliding downward. The two hanging posts can also limit the position of the wire mesh along the diagonal. When the wire mesh is larger in specification, multiple hanging posts can be set, and each minimum-specification grid corresponds to a hanging post, which alternately presses against the left and right sides of the grid. The design position and number of the hanging posts are formed according to the grid structure of the wire mesh.

[0032] Example 2

[0033] Based on Example 1, see the attached Figure 6 and attached Figure 7 A contact switch is arranged on the positioning seat, which contacts the wire mesh to be cut. The wire mesh acts as a switch connected to the control circuit to conduct the circuit, and transmits a signal through the solenoid valve to control the action of the cutter. The contact switch includes a first metal conductive sheet 6 and a second metal conductive sheet 7, which are electrically connected to the circuit including the solenoid valve; the first metal conductive sheet 6 and the second metal conductive sheet 7 are fixedly arranged on the upper surface of the positioning seat 2 through an insulating gasket 8; when the first metal conductive sheet 6 and the second metal conductive sheet 7 contact the wire mesh to be cut at the same time, the wire mesh acts as a switch connected to the control circuit to conduct the circuit, and transmits a signal through the solenoid valve to control the action of the cutter.

[0034] Before the wire mesh is placed, the metal conductive sheet on the positioning seat 2 acts as a switch in the circuit and is in the disconnected state at this time; after the wire mesh is placed, the wire mesh simultaneously contacts the metal conductive sheet on the positioning seat 2 to form a connected loop, the circuit is turned on, and the solenoid valve in the circuit transmits a signal to the drive device of the cutter to drive the cutter to perform cutting action.

[0035] When the circuit is turned on, a signal is transmitted through the electromagnetic valve to control the action of the cutter 5. Therefore, only when the wire mesh sheet 4 is placed on the cutter seat 1 and the positioning seat 2 and the inclination angle of the wire mesh sheet 4 is guaranteed, the cutter can cut.

[0036] A cutter is arranged above the cutter seat, and the cutter cuts the wire end from top to bottom. The cutter can be driven by pneumatic or hydraulic driving force or other common sense methods. Taking pneumatic drive as an example, the motor drives the gear plate to rotate, and the gear plate and the eccentric shaft are connected by a clutch. When the circuit between the positioning seat 2 and the wire mesh is turned on, the solenoid valve transmits a signal to the pneumatic actuator, and the pneumatic actuator controls the clutch, so that the gear plate drives the eccentric shaft to rotate. The eccentric shaft is hinged to the cutter seat, and the cutter is pressed down for cutting. The motor rotates normally, and only after receiving the solenoid valve signal can the motor control the rotation of the eccentric shaft through the clutch. The above content is the driving action of the cutter, which ensures that the action of the utility model is complete and achievable, but it does not belong to the protection scope of the utility model, so the relevant drawings are not provided.

[0037] It is particularly emphasized that when placing the wire mesh, if the wire mesh is not in contact with the first metal conductive sheet 6 and the second metal conductive sheet 7 at the same time, the inclination angle of the wire mesh does not meet the set requirements. At this time, the cutter will not move and will not cut to ensure the cutting quality.
