Abstract

Disclosed is a feeding pipe of an oil-film-type bar feeding machine. The feeding pipe of the oil-film-type bar feeding machine is provided with a feeding groove. The feeding groove is separated into a plurality of large-diameter sections and a plurality of small-diameter sections. The large-diameter sections and the small-diameter sections are arranged in a staggered mode. Therefore, the thickness of the oil film of lubricating oil is increased through the large-diameter sections of the feeding groove so as to effectively give play to the lubrication effect and ensure that a bar can more stably and smoothly slide along the feeding groove.

Description

The feed pipe of oil film type bar feeder

Technical field

The utility model relates to a kind of bar feeder, especially refers to a kind of feed pipe of oil film type bar feeder.

Background technology

General oil film type bar feeder is lubricating oil to be injected in the chute feeder of feed pipe by pump earlier when feeding, make lubricating oil be attached to the cell wall of chute feeder and form one deck oil film, when sliding along chute feeder, a bar can float over the formed oil film of lubricating oil surface by the rotation of itself, so can reduce the frictional dissipation between bar and the feed pipe, can also reduce the noise that push rod produces simultaneously when pushing bar.

Yet as shown in Figure 1, the chute feeder 2 of known feed pipe 1 is to be isometrical extension, make lubricating oil can be restricted in the thickness of the formed oil film of cell wall of chute feeder 2, cause the obtainable lubricant effect of bar also can relatedly to be affected, in the case, bar still can't avoid and the cell wall of chute feeder 2 between produce collision and friction, so the structure of known feed pipe 1 has necessity of improvement.

The utility model content

The purpose of this utility model is to provide a kind of feed pipe of oil film type bar feeder, and it can produce good lubricating effect to bar.

For achieving the above object, the feed pipe of the oil film type bar feeder that the utility model provides includes:

One body has a chute feeder, and this chute feeder is distinguished into most big footpath sections and most path sections, is staggered between this majority big footpath section and this majority path section and arranges.

The feed pipe of described oil film type bar feeder, the section configuration of wherein respectively being somebody's turn to do big footpath section reach respectively, and the section configuration of this path section all takes the shape of the letter U.

The feed pipe of described oil film type bar feeder, wherein this body has the oil filler point of at least one this chute feeder of connection.

The feed pipe of described oil film type bar feeder, wherein the end face of this body is provided with the cover plate of this chute feeder of covering.

The feed pipe of described oil film type bar feeder, include a power source, this power source has a cylinder body, a piston rod, an and interlock plate, one end of this piston rod connects this cylinder body, this interlock plate connects the other end and this cover plate of this piston rod, is driven this body start relatively of this cover plate by the driving of this piston rod.

The feed pipe of described oil film type bar feeder includes a carriage, and this carriage is located at the bottom surface of this body.

Thus, feed pipe of the present utility model utilize this chute feeder respectively should big footpath section design can increase the oil film thickness of lubricating oil, so just can effectively bring into play lubricated effect and reach and make this bar can purpose more stable and that slide along this chute feeder swimmingly.

Symbol description in the accompanying drawing:

10 bar feeders, 12 boards, 20 feed pipes, 30 carriages, 40 bodys, 41 chute feeders, 42 big footpath sections, 43 path sections, 44 oil filler points, 45 cover plates, 50 power sources, 52 cylinder bodies, 54 piston rods, 56 interlock plates, 60 bars, 70 lubricating oil.

The specific embodiment

Feed pipe provided by the utility model includes a chute feeder, and in order to carry a bar, this chute feeder is distinguished into most large-diameter portions and most minor diameter parts, is staggered between this majority big footpath section and this majority path section and arranges.

Please consult Fig. 2 earlier, for using the bar feeder 10 of feed pipe 20 of the present utility model, feed pipe 20 of the present utility model is installed in the board 12 of bar feeder 10 and has a carriage 30 and a body 40.

Carriage 30 is located at the bottom surface of body 40, in order to support body 40.

Body 40 has and is an axially extended chute feeder 41, in order to carry a bar 60.Chute feeder 41 is distinguished into most big directly sections 42 and most path sections 43, be staggered between most individual big footpath sections 42 and the most individual path section 43 and arrange, and the section configuration of each big footpath section 42 and the section configuration of each path section 43 is U-shaped.In addition, body 40 also has the oil filler point 44 (in fact needing only at least one) of most connection chute feeders 41, uses for a lubricating oil 70 to flow in the chute feeder 41.Moreover the end face of body 40 is provided with a cover plate 45, in order to hide chute feeder 41.

In order to allow cover plate 45 can automatically be covered on the end face of body 40, feed pipe 20 of the present utility model also provides two power sources 50 (as long as in fact), and each power source 50 has a cylinder body 52, a piston rod 54, and an interlock plate 56.Cylinder body 52 is fixed in board 12, one end of piston rod 54 connects cylinder body 52, interlock plate 56 connects the other end of piston rod 54 and the end face of cover plate 45, makes interlock plate 56 can be driven cover plate 45 lids by elongating or shortening of piston rod 54 if leave the end face of body 40.

By above structure as can be known, after lubricating oil 70 is in oil filler point 44 flow to chute feeder 41, can be attached to the cell wall of chute feeder 41 and form one deck oil film, because the groove of each big footpath section 42 footpath is greater than the groove footpath of each path section 43, so lubricating oil 70 can come thickly than the thickness at each path section 43 formed oil film at the thickness of each big footpath section 42 formed oil film, thus, when bar 60 is pushed in the chute feeder 41 by a push rod (not shown), each big footpath section 42 formed heavy oil film at chute feeder 41 can produce enough lubricant effects to bar 60, also can avoid simultaneously producing between bar 60 and the chute feeder 41 too much collision and friction, so with under known feed pipe 1 is compared, the utility model more can be brought into play lubricated effect and make bar 60 slide into a position to be processed along chute feeder 41 more stable and swimmingly, to reach the purpose of this utility model really.
