Abstract

The utility model relates to a peeling machine which is suitable for stripping rubber sheets at the outer layer of a hydraulic rubber pipe of a weaving type steel wire or a winding type steel wire. The utility model is provided with a positioning core shaft which is connected with a main shaft and is provided with a cutter rack and a balance weight, a rotatable cutter which is provided with a tool bit with large edges and slope angles is arranged on the cutter rack, and the cutter rack is provided with an elastic component which can cause the cutter to reset. When the utility model is used for peeling the rubber pipe, the cutter floats at an interface of the rubber sheet and the steel wire, and cutting depths can be automatically adjusted. Rubber sheet layers are completely peeled off, the steel wire can be not damaged or edges of the steel wire can be not disordered, and therefore, the peeling quality of the rubber pipe is effectively enhanced.

Description

A kind of peeling machine

The utility model relates to a kind of peeling machine that adopts cutting way to peel off the outer rubber of high-pressure and hydraulic sebific duct.

The high-pressure and hydraulic sebific duct is by being composited with braided steel wire or the enhancement Layer that is entwined and inside and outside rubber layer, when pipe joint is withheld at its two ends, must be earlier the outer rubber of termination certain-length be divested.Divest in the mode at machinery at present, a kind of special-purpose peeling equipment that the rubber layer car can be fallen is arranged, its primary structure is: it has a rotary main shaft, by support sebific duct positioning core axle and cutterhead is housed, and cutterhead is provided with two L type supports mounting cutter and counterweight respectively.Add man-hour, adjust the depth of cut, glue pipe socket to positioning core axle, is cut while advancing.Be characterized in that sebific duct does not rotate during peeling, so sebific duct length is unrestricted; In addition, can not produce glue dirt and glue stink, little to environment and operating personnel's health effect; But in the working angles, because cutter is a rigidity, the tool position was constant when sebific duct was inserted in and pulls out, thereby easily injured steel wire or cause the random limit of steel wire, caused the hose assembly qualification rate low; For avoiding this problem, must reduce the depth of cut usually, reserve skim rubber, and then clean with the steel brush removing, increased by a procedure for this reason, reduced working (machining) efficiency.

In order to overcome above deficiency, the utility model provides a kind of peeling machine that can adjust the depth of cut in process voluntarily.

The technical solution of the utility model is rotating big cutting edge inclination cutter head to be housed on the toolframe, and to be provided with the elastomeric element that cutter is resetted.

The utility model is to the peeling of high-pressure and hydraulic sebific duct the time, and cutter floats at rubber and steel wire interface place, adjusts cutting depth automatically, has both divested the rubber layer fully, can not injure steel wire again or cause the random limit of steel wire, has guaranteed the quality of peeling processing.

Be described further below in conjunction with embodiment.

Accompanying drawing 1 is the front view of the utility model complete machine;

Accompanying drawing 2 is the right view of accompanying drawing 1;

Accompanying drawing 3 is looked cutaway view for the master of the utility model toolframe;

Accompanying drawing 4 is the right cutaway view of accompanying drawing 3;

Accompanying drawing 5 is the front view of the cutter of another kind of structure;

Accompanying drawing 6 is the front view of sliding delivering gear;

Accompanying drawing 7 is the right view of accompanying drawing 6;

Accompanying drawing 8 is the front view of the delivering gear of employing leaf spring.

As shown in Figure 1 and Figure 2, motor 1 (also can adopt hydraulic pressure or air motor) is installed on the support 2, and its main shaft links by support 2 and positioning core axle 3 and cutterhead 4.Cutterhead 4 utilizes two L brackets 5 mounting cutter frame 6 and counterweight 7 respectively.Counterweight 7 is a screw structural, is convenient to adjust the running balance.

As shown in Figure 3, Figure 4, toolframe 6 comprises the delivering gear be made up of nut 8, feed screw 9, tool axis 10, guide post 11 and is made of elastomeric element and cutter rotational pin 14 that back-moving spring 12, removable pin 13 are formed.Cutter 15 is contained on the toolframe 6, has the pin-and-hole that matches with cutter rotational pin 13.As seen from the figure, this be a kind of by cutter rotational pin 14 as fulcrum, the lever construction that an end of back-moving spring 12 and removable pin 13 and cutter 15 constitutes, in fact, can also on cutter, make rotational pin, and on toolframe, open the pin-and-hole that matches, also can reach effect same.Cutter 15 has big cutting edge inclination cutter head, and cutter head is preferably 20 ° to 45 ° of anterior angles, 8 ° to 35 ° of relief angles, 30 ° to 75 ° of cutting edge inclinations.

As shown in Figure 5, the structure that cutter 15 also can adopt knife bar 16 and shaping blades 17 to link, expense hole or make rotational pin on this moment knife bar 16.

Stop cutter around tool axis 10 rotations when the guide post 11 in the delivering gear is used for feed, can save, but then need manually to adjust tool orientation.In addition, delivering gear also can adopt other form, and as Fig. 6, sliding structure shown in Figure 7, it is made up of feed rod 18 that has keyway and lock-screw 19, need not guide post 11, and by keyway control cutter moving direction.

Removable pin 13 is used to reduce resistance, also can save; Also can adopt leaf spring 20 to replace back-moving spring 12 and removable pin 13, as shown in Figure 8.

In addition, can adopt mandrel 3, cutterhead 4, support 5, toolframe 6 and counterweight 7 each cover are installed respectively at the main shaft two ends, and the mode that main shaft is driven by a drive unit.

Its course of work is: at first, according to the latus rectum of high-pressure and hydraulic sebific duct, select the positioning core axle 3 of respective diameters to be installed on the main shaft; Then, unclamp nut 8 a little, turn 9 feeds of feed screw, because the effect of

guide post

11,15 on cutter follows up and does not rotate; After adjusting the cutting size, fastening nut 8; Then adjust counterweight 7; Start peeling machine then, sebific duct is packed into positioning core axle 3, sebific duct will promote the back knife face of cutter 15, force cutter 15 to turn clockwise as shown, and cutter 15 makes removable pin 13 compression reseting spring 12 that moves up, this moment cutter 15 cutter relievinves.When the end face of sebific duct with after the shaft shoulder of positioning core axle 3 contacts, can oppositely spur sebific duct and carry out peeling processing, this moment, cutter 15 will be rotated counterclockwise under spring force and frictional force acting in conjunction, cut sebific duct.In the working angles,, therefore, when running into steel wire behind the cutter 15 excision rubber, will turn clockwise cutter 15 cutter relievinves because spring members acts on power on the cutter 15 less than incision steel wire floor required power; Again since spring force greater than the required incision power of rubber, cutter 15 will be cut again, up to running into the steel wire cutter relieving again; Move in circles, until completion of processing.Therefore, in whole process, cutter 15 is in a kind of quick condition, can adapt to cutting depth automatically, can not damage steel wire floor because of hard row cutting.When from the end face 2-3mm of sebific duct, pull out sebific duct rapidly, can guarantee the not random limit of sebific duct end face.
