Description

Technical Field

[0001] This utility model relates to the field of processing technology for sleeves for brake lines and control lines, and in particular to a device for pulling out broken wires from a mold. Background Technology

[0002] Flat wires within control harnesses, also known as flattened wires, flat-angle wires, or ultra-narrow strips, are irregularly shaped metal wires with a cross-section approximately rounded rectangular. Their thickness ranges from 0.025mm to 2mm, and their width is generally less than 5mm, with a width-to-thickness ratio ranging from 2:1 to 50:1. Flat wires offer unique advantages in control harnesses, such as better heat dissipation, a larger welding contact area, higher fatigue resistance, and superior hardness control.

[0003] Currently, during the process of drawing wire rod into flat wire, wire breakage often occurs. This requires removing the broken wire from the die and re-threading it. However, it is difficult for workers to pull the wire out of the die using pliers, significantly reducing the efficiency of threading the wire and thus affecting the production efficiency of flat wire.

[0004] Therefore, it is desirable to provide a device for pulling broken wires out of the mold, which can solve the above-mentioned technical problems. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example

[0032] This embodiment provides a device for pulling broken wires out of a mold, including a worktable 1, a moving mechanism, and a clamping mechanism.

[0033] In this embodiment, the bottom of the workbench 1 is provided with rollers 2, which facilitates moving the workbench 1 and moving it to a designated position.

[0034] like Figure 1 As shown, the moving mechanism includes a bracket 3, a rotating shaft 4, a gear 5, and a rack 6; the bracket 3 is fixed on the worktable 1; the rotating shaft 4 is horizontally rotatably mounted on the bracket 3; and the gear 5 is sleeved and fixed on the rotating shaft 4.

[0035] In this embodiment, an operating handle 7 is fixed to one end of the rotating shaft 4 to facilitate rotation.

[0036] The workbench 1 is provided with a horizontal sliding groove 8, and the rack 6 is slidably disposed on the sliding groove 8. The rack 6 is located directly below the gear 5 and meshes with the gear 5.

[0037] like Figure 2 , Figure 3 and Figure 4 As shown, the clamping mechanism includes a fixed base 9, two clamping bars 10 and a limiting plate 11; the fixed base 9 is fixed to one end of the rack 6; two inclined channels 12 are horizontally and symmetrically arranged on the fixed base 9; the two clamping bars 10 are slidably arranged in the corresponding inclined channels 12; the front ends of the two clamping bars 10 are provided with mutually compatible clamping parts 13.

[0038] In this embodiment, first support bars 14 are symmetrically fixed on both sides of the fixing base 9, and second support bars 15 are fixed to the rear ends of the two clamping bars 10. A spring 16 connects the first support bars 14 and the second support bars 15 on the same side of the fixing base 9 to facilitate the reset of the two clamping bars 10.

[0039] The limiting plate 11 is vertically fixed on the workbench 1 and is located directly in front of the fixing seat 9; the top center of the limiting plate 11 is recessed with a placement groove 17, which extends through the front and rear sides of the limiting plate 11.

[0040] like Figure 5As shown, during operation, the mold is first placed against one side of the limiting plate 11, and the broken wire passes through the placement groove 17; the handle 7 is rotated to move the fixed seat 9 forward until the front ends of the two clamping bars 10 abut against the limiting plate 11; the two clamping bars 10 are slidably set in the inclined channel 12 of the fixed seat 9, so the two clamping parts 13 will open; then the worker rotates the rotating shaft 4 in the opposite direction, and the clamping parts 13 will clamp the broken wire. At this time, the mold is limited by the limiting plate 11, and finally the broken wire is pulled out of the mold.
