Abstract
The utility model discloses a nylon casing removing cutter, which is characterized in that the nylon casing removing cutter comprises a cutter bar, wherein a plurality of spiral teeth or sawtooth teeth which are arranged in parallel with the axis of the cutter bar are uniformly arranged on the cutter bar along the circumferential direction, the spiral teeth are leftwards spiral and the rear end of the cutter bar is of the shape of a polygon prism which is used for sheathing a wrench. The nylon casing removing cutter can be directly chiseled or screwed into a nylon casing according to the shape of the teeth to cut the inner wall of the nylon casing into vertical or spiral grooves, the nylon casing removing cutter and the nylon casing can be integrally connected and then a bolt wrench can be used for directly taking out the nylon casing which is preset in a sleeper. Therefore, the nylon casing removing cutter has the advantages that the cutter is simple and convenient to operate, the unnecessary intermediate links are omitted, the time and the labor are saved and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of specific purpose tool that is used for taking out rail track sleeper nylon sleeve, particularly a kind of nylon sleeve cutter that unloads.
Background technology
At present, nylon sleeve mainly contains dual mode in the taking-up rail track sleeper: a kind of electric drill that is to use is broken with the nylon jacket pipe bit, with colluding for a short time fragment is ticked again; Another kind is through hot melt nylon sleeve to be heated, and ticks with instrument such as colluding for a short time after making it softening again.The equal complex operation of this dual mode is wasted time and energy inefficiency.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of easy and simple to handle, time saving and energy saving, high efficiency unload the nylon sleeve cutter.
The utility model is achieved in that it has a knife bar; On knife bar, along the circumferential direction be laid with many helical form teeth or with the zigzag teeth of cutter spindle line parallel; Described helical form teeth are left-handed, and the knife bar rear end is the multi-edge column-shaped that is used for sheathed spanner.
The above-mentioned nylon sleeve cutter that unloads, described knife bar front end be stepped and point diameter less than the center diameter, so that use.
The above-mentioned nylon sleeve cutter that unloads is axially arranged with a plurality of annular grooves that the zigzag teeth are cut off in the knife bar upper edge, so that the cutting nylon sleeve.
The utility model has the advantages that: this unloads the nylon sleeve cutter and can directly dig into according to the shape of teeth or screw in the nylon sleeve; The nylon sleeve inwall is cut into vertical or spiral helicine groove; The two firmly is connected as a single entity, just can the nylon sleeve that be preset in the sleeper be directly taken out with track wrench again.Easy and simple to handle, saved unnecessary intermediate link, time saving and energy saving, increase work efficiency greatly.

The specific embodiment
Embodiment 1
Like Fig. 1, shown in Figure 2, this unloads the nylon sleeve cutter has a knife bar 1, knife bar 1 front end be taper type or stepped and point diameter less than knife bar 1 middle part diameter, present embodiment is example with stepped.Be laid with the helical form teeth 101 of many protrusions at knife bar 1 middle part and front end edge circumferencial direction; Described helical form teeth 101 are for left-handed and be example with six helical form teeth 101; Knife bar 1 rear end is the multi-edge column-shaped that is used for sheathed spanner, and present embodiment is example with the hexagon.
During use; This is unloaded the insertion of nylon sleeve cutter is preset in the nylon sleeve in the sleeper; Clamp knife bar 1 rear end and left-handed with spanner, knife bar 1 is screwed in the nylon sleeve, because nylon sleeve is installed in the sleeper through right-handed thread; Nylon sleeve is screwed out in by sleeper, convenient and swift.
Embodiment 2
Like Fig. 3, shown in Figure 4, this unloads the nylon sleeve cutter has a knife bar 1, knife bar 1 front end be taper type or stepped and point diameter less than knife bar 1 middle part diameter, present embodiment is example with stepped.Be laid with many zigzag teeth 102 with knife bar 1 parallel axes at knife bar 1 middle part and front end edge circumferencial direction; Present embodiment is an example with six zigzag teeth 102; Be axially arranged with a plurality of annular grooves 103 that zigzag teeth 102 are cut off at knife bar 1 middle part and front end edge, so that the cutting nylon sleeve.Described knife bar 1 rear end is the multi-edge column-shaped that is used for sheathed spanner, and present embodiment is example with the hexagon.
During use; This is unloaded the nylon sleeve cutter digs in the nylon sleeve that is preset in the sleeper; Zigzag teeth 102 cut into vertical groove with the nylon sleeve inwall, clamp knife bar 1 rear end and left-handed with spanner again, because nylon sleeve is installed in the sleeper through right-handed thread; Nylon sleeve is screwed out in by sleeper, convenient and swift.
Claims (3)
1. one kind is unloaded the nylon sleeve cutter; It is characterized in that: it has a knife bar; On knife bar, along the circumferential direction be laid with many helical form teeth or with the zigzag teeth of cutter spindle line parallel, described helical form teeth are left-handed, the knife bar rear end is the multi-edge column-shaped that is used for sheathed spanner.
2. the nylon sleeve cutter that unloads according to claim 1 is characterized in that: described knife bar front end be stepped and point diameter less than the center diameter.
