Description

Technical Field

[0001] The utility model relates to the technical field of metal wire fixed-length cutting, in particular to a metal wire fixed-length cutting device. Background Art

[0002] Concrete sleepers are concrete products used as railway sleepers. They are mainly used to bear the tracks, fix the tracks, relieve impacts, disperse loads, and ensure railway safety.

[0003] In order to increase the strength of concrete sleepers, metal wires will be preset in the template during concrete pouring, which will enhance the strength of the concrete sleepers after later pouring and forming. Therefore, the purchased rolled metal wire bodies will be cut into required sizes in the early stage.

[0004] The cross-section of the metal wire is generally a circular structural surface. After it is produced, it is generally rolled up so that it can be cut into sections at a fixed length according to the design requirements of the drawings in preparation for the later casting of concrete sleepers. Therefore, a metal wire fixed-length cutting device is needed.

[0005] At present, when cutting the metal wire to a fixed length, it is generally done by manually finding one end of the rolled metal wire and pulling it out, and then holding a handheld cutting knife in the other hand to cut the metal wire to a fixed length. This manual fixed-length cutting method has poor stability, which greatly reduces the fixed-length cutting quality of the metal wire for concrete sleepers.

[0006] Therefore, a wire cutting-to-length device is needed to solve the above problems. Utility Model Content

[0011] Furthermore, the top-view cross-section of the knife opening is a V-shaped through-opening, and the top-view cross-section size of the knife opening is not less than the top-view cross-section size of the cutting knife.

[0012] Furthermore, a transverse center axis of the top view of the metal wire coincides with a transverse center axis of the top view of the cutting knife.

[0013] Furthermore, the coiled metal wire body is fixedly sleeved on the outer wall of the roller, and there is a gap between the outer wall surface of the coiled metal wire body and the left end surface of the workbench.

[0014] Furthermore, the positioning cylinder and the positioning chuck are a group, a total of two groups, and are longitudinally symmetrically arranged on a fixed-length movable seat. The side cross-section of the positioning clamp groove is an arc-shaped structure and is a left-right through-type and matches the side circular cross-section of the metal wire.

[0018] 2. The utility model further improves the stability and anti-slip property of the metal wire clamping by arranging an arc-shaped positioning clamp groove matching the outer wall of the metal wire on the positioning clamp head, and arranging a damping anti-skid layer on the inner groove wall of the positioning clamp groove, thereby ensuring the effect of cutting the metal wire for concrete sleepers into segments with a fixed length in the later stage.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5 A wire fixed-length cutting device comprises a fixed-length movable seat 6, a main bottom plate 1 is arranged below the fixed-length movable seat 6, a side plate 11 and a supporting plate 3 are arranged on the main bottom plate 1, a roller 12 is rotatably arranged on the side plate 11, a coiled wire body 2 is arranged on the roller 12, a wire 21 is arranged on the coiled wire body 2, a workbench 31 and a roller motor 4 are arranged on the supporting plate 3, a roller disc 41 is arranged on the motor shaft of the roller motor 4, and the workbench 31 is provided with a roller motor 4, and a roller motor 4 is provided with a roller motor 4. 1 is provided with a bracket 5 and a knife opening 32, the bracket 5 is provided with a cutting cylinder 51, the piston rod of the cutting cylinder 51 is provided with a cutting knife 52, the fixed-length movable seat 6 is provided with a directional brake wheel 61 and a positioning cylinder 62, the positioning cylinder 62 is provided with a positioning chuck 7, and the positioning chuck 7 is provided with a positioning clamping groove 71, the coiled metal wire body 2 and the metal wire 21 are integrated, and the metal wire 21 is to find the end of the coiled metal wire body 2 and directly pull it out to discharge the material.

[0027] In detail, the pressure roller motor 4 and the pressure roller disc 41 are a group, which are two groups symmetrical in the longitudinal direction. The two pressure roller discs 41 are in extrusion and rolling contact with the outer wall surface of the metal wire 21. When the pressure roller motor 4 is started, the upper pressure roller disc 41 rotates counterclockwise, and the lower pressure roller disc 41 rotates clockwise, thereby improving the stable rightward guided conveying of the metal wire 21.

[0028] Furthermore, the top-view cross-section of the knife opening 32 is a V-shaped through-opening, and the top-view cross-sectional size of the knife opening 32 is not smaller than the top-view cross-sectional size of the cutting knife 52. When cutting into sections, the cutting knife 52 will pass through the knife opening 32 to avoid collision with the workbench 31.

[0029] Furthermore, the horizontal center axis of the top view of the metal wire 21 coincides with the horizontal center axis of the top view of the cutting knife 52 , thereby ensuring that the clamped metal wire 21 is accurately cut into segments by the cutting knife 52 .

[0030] In more detail, the rolled metal wire body 2 is fixedly mounted on the outer wall of the roller 12, and there is a gap between the outer wall surface of the rolled metal wire body 2 and the left end surface of the workbench 31. When the metal wire 21 is pulled to the right to be released, the rolled metal wire body 2 will roll through the roller 12 to avoid colliding with the workbench 31 and affecting the discharge of the material.

[0031] In general, the positioning cylinder 62 and the positioning chuck 7 are a group, with a total of two groups and are longitudinally symmetrically arranged on the fixed-length movable seat 6. The side cross-section of the positioning clamp groove 71 is an arc-shaped structure and is a left-right through-type and matches the circular cross-section of the metal wire 21 when viewed from the side. When the positioning cylinder 62 is started, the positioning chucks 7 on both sides will match and stably clamp the manually straightened metal wire 21.

[0032] The inner groove wall of the positioning clamp groove 71 is provided with a damping anti-skid layer 8, and the damping anti-skid layer 8 is made of NBR nitrile rubber material, has excellent damping anti-skid, durability, corrosion resistance, and wear resistance.

[0033] Finally, the side cross-section of the fixed-length movable seat 6 is a U-shaped structure, and the number of the directional brake wheels 61 is four and they are symmetrically arranged at the lower end of the fixed-length movable seat 6. The directional brake wheels 61 can only roll stably in one direction and have a braking function, so that the fixed-length movable seat 6 can be stably directional moved left and right and braked and positioned in real time, thereby achieving the effect of positioning and clamping the metal wire 21. The four directional brake wheels 61 are not easy to tip over and are stable and reliable.

[0034] Working method: first pull out a section of metal wire 21 from the coiled metal wire body 2 from left to right, pass the section of metal wire 21 between the two pressure rollers 41, and then continue to pull the metal wire 21 to the right until it is above the fixed-length movable seat 6, first straighten the section of metal wire 21 to the right, then take a ruler and measure the required fixed-length size to the right with the right end face of the cutting knife 52 as the reference, mark the metal wire 21 with a marker, and then move the fixed-length movable seat 6 to the left through the directional brake wheel 61, and when the positioning chuck 7 is aligned with the current marked mark, stop pushing the fixed-length movable seat 6 and brake the directional brake wheel 61,

[0035] Then the positioning cylinder 62 is started, and its telescopic rod extends out and drives the positioning clamps 7 on both sides to stably clamp the metal wire 21. Finally, the cutting cylinder 51 is started, and the cutting knife 52 is driven by its piston rod to move downward quickly and cut the metal wire 21 into segments.

[0036] The above operation improves the quality of the cut-to-length segments of the metal wire 21 for concrete sleepers as a whole.

[0037] In addition, by providing an arc-shaped positioning clamp groove 71 on the positioning clamp 7 that matches the outer wall surface of the metal wire 21, and providing a damping and anti-skid layer 8 on the inner groove wall of the positioning clamp groove 71, the stable and anti-skid property of the clamping of the metal wire 21 is further improved, thereby ensuring the effect of later cutting the metal wire 21 into segments of fixed length for concrete sleepers.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
