In the present embodiment, the size of tubing and angle all can be regulated according to the demand of product, and utilize simple circuit to realize that its automation is to reach the purpose of efficient stable volume production, connect the circuit of next step during each step Overstroke by travel switch, stability and high safety, and easy to maintenance.
Utilize the method for cutting machine production pipe fitting of the present invention as follows:
GB red copper bend pipe tools take production specification as DN25 is example, adopts φ 28 * 1.1(diameter * thickness) copper tube, cutting length be 69/99(as shown in Figure 5), as calculated, angle [alpha] is 62 ° between cast-cutting saw slice and the tubing.
Step 1, to select specification be preposition anchor clamps 12 and the rolling clamp 23 of φ 28, and install to respectively in the middle of clamping fixture seat 13 and the turnbarrel 9.
Step 2, unclamp the fixed screw for the fixed angle disk, anglec of rotation disk 17 is transferred to 62 ° with the angle between cast-cutting saw slice 15 and the tubing 27.
Step 3, the copper tube of φ 28 * 1.1 end from cutting machine is inserted, successively by rolling clamp 23 and preposition anchor clamps 12, and expose certain-length, exposed length surpasses cast-cutting saw slice 15 positions, and a little just can.(usually raw material are all long, and outer one section of the equipment that is exposed at is used material supporting rack and protected, and prevents that material from throwing away when High Rotation Speed, get rid of tubing curved even hurt sb.'s feelings, and material supporting rack is tubing cutting indispensable facility commonly used, tired stating among the present invention.)
The stroke of step 4, adjusting feeding oil gas cylinder 6, the control cutting length.
Step 5, the starting device power supply is opened motor switch, restarts the equipment automatic switch, and equipment begins to enter automatic production cycle.Concrete action is as follows:
1, preposition clamping cylinder 14 piston-advance promote preposition anchor clamps 12 tubing are clamped.(with 11)
2, rotation clamping cylinder 20 piston-retraction, rolling clamp 23 unclamps.(first circulating clamp is in releasing orientation, and this instruction ignore directly enters next step).
3, feeding oil gas cylinder 6 pistons are return, and rotating mechanism supporting seat 11 and rolling clamp 23 are retracted original position.(first circulation, when the rotating mechanism supporting seat was in the home position, this instruction ignore directly entered next step).
4, rotary cylinder 18 pistons are return, and by promoting tooth bar 19 pulling gears 10, rolling clamp are return original angle.(first circulation, when rolling clamp was in original angle, this instruction ignore directly entered next step).
5, motor pushing cylinder 16 piston-advance will push away before motor 1 and the cast-cutting saw slice 15, and the tubing front end is cut off.
6, motor pushing cylinder 16 piston-retraction withdraw from motor 1 and cast-cutting saw slice 15.
7, preposition clamping cylinder 14 piston-retraction, preposition anchor clamps 12 are opened.
8, rotation clamping cylinder 20 piston-advance, rolling clamp 23 clamps.
9, rotary cylinder 18 piston-advance promote gears 10 Rotate 180s ° (anglec of rotation can be controlled according to the piston stroke length that product demand is regulated rotary cylinder 18) by promoting tooth bar 19, thereby make tubing Rotate 180 °.
10, feeding oil gas cylinder 6 piston-advance promote the rotating mechanism supporting seat by linear bearing, thereby send a stroke (as calculated, stroke should be transferred to 84mm) forward herein with tubing.
11, preposition clamping cylinder 14 piston-advance promote preposition anchor clamps 12 tubing are clamped.(with 1)
Equipment is according to above step automatic job, until a tubing cutting is complete.
Step 6: reload, when tubing was accomplished last product, rotary cylinder was owing to press from both sides less than tubing the excess of stroke, equipment can stop circulation automatically, and at this moment, operating personnel take out the product tailing, change new tubing, again press automatic switch, equipment reenters automatic cycle.
The advantage of Full-automatic angle-adjustable tube cutting machine of the present invention is:
1, cost simple in structure is low, and the present invention is simple in structure, and the driving member of employing and electric controling element all are the most frequently used.
2, step is simple, and automation circulation step of the present invention is actual to only have for 10 steps, and control circuit is simple and easy to maintenance.
3, reliable and stable, each step of the present invention is directly controlled next step with travel switch, the random step can not occur, thereby guarantees constant product quality.
4, safety, because so pipe feeding operation raw material all are the tubing of growing usually, the equipment automatic cycle cycle is longer, do not need people directly rotation and promotion tubing, load onto transparent safty shield in the working position, guarantee operating personnel's safety, only need open safty shield when reloading and just can operate.
5, efficient is high, production efficiency of the present invention is high, delay time between each step only 0.5 second (using the time Control), add running time, whenever cut a Cycle of the products, can be controlled in minimum 10 seconds according to the material difference, add the time that the process of reloading consumes, machine is the highest per hour can blanking 300, according to the mode of manufacture that a people sees three machines, can produce about 800 in the time of everyone one.And manually cutting the tubing that two ends are mutually angle, everyone is at most 200 of blankings per hour.
The present invention has filled up both at home and abroad the blank that is mutually at the cutting two ends aspect the automatic equipment of tubing of angle, the producer of domestic production pipe fitting is numerous at present, similar equipment there is very large demand, this equipment can be the cost of labor of product saving more than 10% of elbow class, with the spillage of material more than 5%, very large promotion prospect is arranged.
Should be understood that this embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
