Description

A kind of band saw with magnetic-type lid door

Technical field

The utility model relates to band saw, and it is a kind of band saw with magnetic-type lid door.

Background technology

Band saw, is applied to timber processing and working metal, is also applied to various other materials. Its name derives from its blade and comprises metal tape and tooth. This strip metal band is vertically installed between 2 two larger wheels. Band saw is used in the irregular shape of otch. The radius of its saw curve is determined by the thickness of blade.

Band saw of the prior art, it comprises shelf, includes upper belt-wheel and lower belt wheel in shelf, lower belt wheel is connected with motor, can drive metallic decoration wire to rotate as driving wheel; Upper belt-wheel is driven pulley, and for keeping the rotation use of metallic decoration wire, walking about of saw blade makes the continuous cutting panels of wood of sawtooth on saw blade.

Because in use easily causing wood chip etc., band saw enters in its shelf, need operating personnel to carry out regular cleaning to it, after having cleared up, debug (maintenance after band saw damage simultaneously, also to debug accordingly), debug process is strict with operating personnel will cover door locking post debugging, but most of operating personnel are because think that process is loaded down with trivial details, therefore many not locking debug, once there is accident, especially saw blade is thrown out of, and will cause serious personal injury.

Therefore need a kind of lid door opening/shutting mode closing of opening, enough reduce the loaded down with trivial details opening-closing process of debug process middle cover door, handled easily personnel debugging.

Utility model content

Goal of the invention of the present utility model is in debug process, to open and close loaded down with trivial details problem in order to solve lid door, a kind of band saw with magnetic-type lid door is provided, the loaded down with trivial details degree in lid door opening-closing process can be reduced to greatest extent, the danger producing in debug process can be prevented simultaneously.

In order to realize foregoing invention object, the utility model has adopted following technical scheme: a kind of band saw with magnetic-type lid door, comprise shelf and turnover cover plate, described cover plate and shelf one side are rotationally connected, described shelf comprises the operating side of cutting material and the change-over terminal being connected with cover plate, the operating side of described shelf is provided with multiple magnetic structures, described magnetic structure comprises two magnetics that can attract each other, lay respectively on the shelf of operating side and on corresponding cover plate, between described shelf and cover plate, be also provided with at least one place position limiting structure.

Preferably, described magnetic structure is uniformly distributed along the periphery of cover plate.

Preferably, described position limiting structure comprises securing member and fixed block, and described fixed block is provided with the screwed hole coordinating with securing member.

Preferably, described fixed block is magnetic, and securing member is through the magnetic on cover plate and be tightened against the magnetic on shelf.

Preferably, described in the magnetic that is positioned on cover plate be magnet, the magnetic that is positioned at shelf operating side is formed from steel.

Preferably, the outside of described cover plate is also provided with the handle that opens and closes use.

Compared with prior art, adopt the band saw with magnetic-type lid door of technique scheme, there is following beneficial effect:

Adopt the band saw with magnetic-type lid door of the present utility model, between cover plate and shelf, attract each other by magnetic structure, cover plate can be covered on shelf, and with certain magnetic attraction, make the lid door operating side that is adsorbed in shelf tightly, in the time opening cover plate, need certain power just can open it, and there is no the structure fastening, have 2 place's advantages:

First, in the debug phase, need to open time, only need firmly one to draw, can open cover plate, conveniently opening and closing.

Secondly, in the debug process of saw blade, throw away even if saw blade breaks, the magnetic attraction of cover plate can provide certain barrier force, prevents that it from flying out outside shelf, protection operating personnel.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

A kind of band saw with magnetic-type lid door as shown in Figures 1 to 4, comprise shelf 1 and cover plate 5, cover plate 5 is rotationally connected (junction can adopt hinge or bearing pin etc.) with shelf 1 one sides, realize the upset of cover plate 5, the one end of cutting the materials such as wooden unit on shelf 1 is operating side, operating side is provided with multiple magnetic structures, magnetic structure comprises two magnetics that can attract each other, magnetic lays respectively on the shelf 1 of operating side and corresponding cover plate 5 inner surfaces, between shelf 1 and cover plate 5, be also provided with 2 place's position limiting structures, position limiting structure is for realizing cover plate 5 closely covering on shelf 1.

Magnetic on shelf 1 and cover plate 5 can be: 1 place is magnet 50, and another place is iron and steel or nickel block; Or 2 places are the magnet 50 attracting each other. In the present embodiment, consider cost, therefore adopt magnet 50 to coordinate piece of stainless steel 10, wherein magnet 50 is positioned at cover plate 5 inner surfaces, and piece of stainless steel 10 is arranged in shelf 1.

Position limiting structure can adopt multiple formation, such as: adopt the various ways such as lock core is locked on cover plate 5 on shelf 1, and latch is sealed, slide block clamping. Position limiting structure in the present embodiment is comparatively simple, employing be that bolt mate with threaded holes 100 is tightened.

Wherein screwed hole 100 is positioned on bloom 10 (if magnet 50 is positioned at shelf 1, on magnet 50, beating screwed hole 100 relatively requires great effort, and magnet 50 easily bursts apart, the setup and use life-span is lower like this, therefore bloom 10 is arranged in shelf 1), magnet 50 is provided with the through hole 500 wearing for bolt.

Position, the corresponding operating side of upper and lower belt wheel in shelf 1 is equipped with above-mentioned position limiting structure, and upper and lower two position limiting structures can well be divided equally power, avoid stress too concentrated.

The outside of lid door is also provided with the handle 52 that person easy to use opens and closes.

The above makes preferred embodiment of the present utility model, does not depart from for the person of ordinary skill of the art under the prerequisite of the utility model principle, can also make some modification and improvement, and these also should be considered as protection domain of the present utility model.
