Abstract
A pair of hyperbolical planetary rollers which are obliquely arranged is placed in straightening cylinder of reinforcing bar straightening and cutting machine, the reinforcing bar is passed through between two rollers and holden by said two planetary rollers under the action of springs, and when the straightening cylinder is turned, the two planetary rollers can produce an axial (along axis direction) component velocity to draw the reinforcing bar and make it move forward, and when cutting reinforcing bar, the upper tool holder drives lever under the action of ram head to make the rotating disk move to make the two planetary rollers separate so as to make the bar temporarily stop movement. Moreover, in order to make said machine continuously work, a spring resetting mechanism is placed.
Description
The present invention relates to the pause mechanism of traction when cutting off on a kind of concrete-bar straightening-cutting machine that is used for the reinforcing bar processing industry; it is that draw-gear has been installed on straightening drum; rotation drive reinforcing bar by straightening drum travels forward; and guarantee when bar cutting, to drive pause device, make the mechanism of the automatically temporary transient stop motion of reinforcing bar.
Concrete-bar straightening-cutting machine is a cement prefab factory, the widely used reinforcing bar process equipment of building industry; Also have broad application prospects in industries such as automobile, bicycles.
Existing development decades of China, the history of producing concrete-bar straightening-cutting machine, particularly new product continues to bring out in recent years, but up to this point, the concrete-bar straightening-cutting machine ubiquity of selling on the market following problem:
1. reinforcing bar because of the time-out problem of haulage gear fails to be well solved always, so often occur connecting cutting phenomenon, makes reinforcing bar cut out many broken heads when fixed ruler cutting, causes waste.
2. the structure of the concrete-bar straightening-cutting machine structure too complicated (as the complicated gearbox of needs) of traction element particularly causes the cost height, and the selling price costliness is used producer to bear and felt difficulty.
At the problems referred to above, the invention provides the particularly structure of traction element of a kind of structure that can simplify concrete-bar straightening-cutting machine greatly, can be implemented in when cutting off reinforcing bar haulage gear simultaneously and temporarily stop reinforcing bar automatically and travel forward.
For reaching this purpose, in the straightening drum of concrete-bar straightening-cutting machine, be provided with the hyperboloid planetary rollers of pair of angled sheet, planetary rollers is rotated with straightening drum, reinforcing bar passes between two planetary rollers, make planetary rollers compress reinforcing bar by spring, when straightening drum rotated, planetary rollers promptly drove reinforcing bar and travels forward.Reinforcing bar stops to send to automatically when cutting off for assurance, adopted a lever with the radial position of planetary rollers and support with shear the moving up and down of upper tool post and connect, when upper tool post under the tup effect, move downward when also not cutting off reinforcing bar, by the inclined-plane on lever, the rotating disc a pair of planetary rollers of traction reinforcing bar is separated, reinforcing bar stops to travel forward at this moment, and then upper cutter cuts off reinforcing bar under the tup effect.Tup rises after cutting off reinforcing bar, and lever and rotating disc reset under spring action, and planetary rollers compresses reinforcing bar again under spring action, and reinforcing bar moves forward again, up to cut off next time.
The invention has the advantages that:
1. simple and compact for structure, can solve the time-out problem of haulage gear when cutting off reinforcing bar, effectively overcome to connect and cut phenomenon, save material.
2. utilize the concrete-bar straightening-cutting machine of this mechanism design, its complete machine structure is more simple, and without gearbox, none gear can reduce manufacturing cost significantly.
The present invention is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the pause mechanism schematic diagram of traction when cutting off of concrete-bar straightening-cutting machine of the present invention.
Accompanying drawing has been expressed principle of the present invention and has been constituted, when straightening drum 1 rotation, drive upper bracket 3 and lower carriage 12, upper planet roller 4 and lower planet roller 5, rotating disc 6 rotates together, have between the axis of each planetary rollers and the axis of straightening drum≤45 ° inclination angle, reinforcing bar 8 passes between two planetary rollers, planetary rollers 4 and 5 is pressed on the reinforcing bar 8 with certain pressure by spring 2, because the inclination of hyperboloid planetary rollers 4 and 5, when it rotates, to produce the axially component velocity of (along the reinforcing bar axis direction), thereby realize the traction reinforcing bar 8 proal purposes that rotatablely move by straightening drum 1.When cutting off, tup 16 is under transmission mechanism drives, move downward and beat on upper tool post 14, upper tool post 14 is connected with upper cutter 15, then upper cutter 15 moves downward with upper tool post 14, upper tool post 14 promotes lever 9 around fulcrum 10 swings simultaneously, two rollers 7 are equipped with in the end of lever 9, promoting rotating disc 6 by it moves right, under rotating disc 6 end chamfer effects, make upper bracket 3 and upper planet roller 4 and lower carriage 12 and lower planet roller 5 motion up and down respectively, thus planetary rollers 4 and opening in 5 minutes up and down, reinforcing bar 8 stops to travel forward immediately, and this moment, upper cutter 15 just began to cut off reinforcing bar 8 with lower cutter 17.After reinforcing bar 8 is cut off, tup 16 moves upward under transmission mechanism drives, upper tool post 14 also upwards resets, lever 9 returns to initial position under the effect of spring 13, rotating disc 6 is also got back to initial position under the effect of spring 11, planetary rollers 4 and 5 compresses reinforcing bar 8 again under the effect of spring 2, reinforcing bar 8 begins again to travel forward and cuts off up to next time.
