Abstract

PURPOSE:To perform all bender processes by one input data by giving a controlling circuit function to divide data and divide feed to several number of times when data having a value larger than one feed quantity of a truck is inputted. CONSTITUTION:In the circuit 9 that controls movement of members for bending, data for working are inputted from an inputting section 9a and stored in a memory 9d. When a pipe bender is started, data related to feed length and data of twisting and bending are taken out in a central processing section 9b. Data related to feed length and maximum feed length of chuck truck are compared. When data having value larger than one feed quantity of the truck are inputted, the data are transferred to a controller 9f through a transfer section 9c, and at the same time, data of twisting and bending are transferred. These data are divided automatically, and feeding is executed successively basing on divided data.

Description

[Detailed description of the invention] This invention relates to a pipe bender device.

In recent years, numerically controlled pipe bender devices that automatically cut pipes based on a program have been put into practical use.

By the way, in conventional pipe bender equipment, the amount of feed υ between pipe bends is determined by the feed stroke, so when processing a long pipe, it is necessary to process it several times. The problem was that it had to be done separately. Moreover, if the processing is divided into several times,
Processing data needs to be corrected according to the method of dividing the data related to the feed, and the data must be re-entered each time the processing is divided (if the processing is divided into 6 times, 61 new pieces of data will be required). There was a problem with this.

Therefore, the present invention provides a pipe bender that can perform all processing automatically by inputting all the data once, whether it is the feed stroke of the pipe bender device or the processing of a long pipe. The purpose is to provide equipment.

In the present invention, in order to achieve the above object, the chuck cart is transported once! 11 m j ') When large data is input, this data is dynamically divided into parts νi and sent in several parts.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, 6 is a feed unit having a collet chuck 1 and a twisting motor 4, which is placed on a chuck stand $2.

The chuck cart 2 is provided so as to be able to move forward and backward by a predetermined length (5 [1ts] in this example) in the left-right direction in the drawing.

The collet chuck 1 holds and opens the pipe 5 in synchronization with the action of the chuck cart 2, and by combining the movement with the chuck cart 2, the pipe 5 can be sent out or pulled back. can. The twisting motor 4 is used to give a twist to the pipe 5, so that the pipe 5 can be subjected to three-dimensional processing.

Next, 6 is a bending die, 7 is a clamp, and 8 is a pressure, which are numbered so as to perform bending on the pipe 5. That is, when the pipe 5 is transferred to a predetermined position by the feed unit B, the clamp 7 and the pressure 8 act hyperactively and clamp the pipe 5 between the bending die 6 and the bending die 4 and the clamp 7. With the pipe 5 held between them, the pipe 5 is rotated by a predetermined angle of 1 degree along the pressure 8 to bend the pipe 5.

Note that the collet chuck 1, the feed unit 6,
The twisting motor 4, the bending die 6, the clamp 7, and the pressure 8 are designed to automatically perform processing according to a program preset in the control circuit 9.

Next, the control circuit 9 will be explained. In the tree V.1j, the control circuit 9 is valenced 75 times as shown in FIG.

μm) Input section 2a, display 141s9g, and central processing section? b. A data dividing section 9e, which uses the data 1 transfer capital 9C and the memo 'J9d as main rods, and a programmer gel controller 9f (hereinafter referred to as a controller). In addition, in the diagram, cylinder 1" + IJJ 1
4. The clamps 10 are individually installed in the V throat chuck 1, the feed unit 6, the mold 6, the clamp Z & pressure pressure 8, and are individually controlled by the controller 9f. In addition, the twisting motor 4 is equipped with a rotary encoder 4a.
), these are also controlled by the controller 9f.

Next, the action and effect will be explained.

First, data for processing is inputted from the input section 9a. This data is stored in the memory 9d in a format as shown in FIG. Next, the processing of the pipe 5 based on this data will be explained: - First, the pipe 5 is loaded in the collet chuck 1 in a predetermined state, and then the pipe bender equipment NB is started. Then, first, data L(], tension O1 bending If'< B 1 regarding the feed length are taken out from the memory 2d to the medium heat processing section 2b, and among these data LD
and the maximum feed length LD of the chuck cart 2 (this corresponds to step 1 in FIG. 8). In this case, in this example, the same data LQ is transferred to the controller 9f via the data transmission fA section 9C, and the data of the twist 01 bending data B1 is also transferred to the controller 9f.For this reason, controlloff
2f, as shown in FIGS. 2 and 6, the bending mold 6 and the clamp 7 are integrated to form an angle B along the pressure 8.
At the same time as one rotation, during this bending operation, the chuck cart 2
Loosen this chuck and move back by the LD amount. When the bending operation J7 is completed, the chuck ring 7 and pressure 8 are removed by bending the chunk (!:ij), and while holding the pipe 5, the chuck cart 2 returns to the moped 1 position and performs a twisting force, but the main Since the twist angle is 0 in the data, no twisting operation is performed here.

At this point, the operation based on the data of one step is completed, and the next step is superior. When moving to the next process, the next data L4. J.

B2 is central processing '4p'S from memory 9d? (5C9b
be taken in. Then, the central processing unit i 9b performs all calls to the routine shown in FIG. 8 regarding the sending length data. First, in the format of step 1, in this example, the data related to the transfer LII', J:L1>LD, so proceed to step 2, and divide the data by division (%ir:tg
ij minutes only) and Amafib was criticized. Then proceed to step B and set the feed length LD (maximum feed length of the chuck cart).
, bend fiRi, bend B2 data to controller 9
Transfer to f. For this reason, after tightening the clamp 7 and fixing the pipe 5, the chuck cart 6 loosens its chuck and retreats by LD length as shown in FIG. rear,
The chuck cart 2 moves forward by LD length. Here, for example, A=
3. Assuming that M=20, the above-mentioned feeding is repeated six times through steps 6 to 5, and then the steraf.

At step 6, data on the remaining 20 m of feed, twist R1, and bend B2 are output from the data transfer section 9C to the controller 9f. Then, as in the process described above, the chuck cart 2 rotates by angle B2, and at the same time, during this bending operation, the chuck cart 2 loosens the chuck and retreats by 20[alpha] to perform the bending B2 rotation. and,
When the pipe 5 is bent, the chuck is tightened to remove the clamp 7 and the pressure 8, and while the pipe 5 is being held, the chuck cart 2 returns to its original position υ while adjusting the twist angle R1.
amount of rotation. The state after the above-mentioned processing is completed corresponds to FIG. 5 (in the figure, the feed length is shown shorter than it actually is).

In this way, in this example, even if data larger than the maximum feed length of the chuck cart 2 is input, the data is automatically divided and feed is executed sequentially using the divided data. , operators, etc. can operate the pipe bender device without paying any consideration to the size of the data.

In addition, in this example, the case where the i4 F) feed is performed after 6 times of feeding is explained as an example, but any length of pipe can be used as long as it can be attached to the pipe bender equipment fffi BK. It goes without saying that we can also handle the same items: B
It is.

That is, the present invention is not described in the claims.41.)
Depending on the configuration, the pipe bender device can be transferred)
Even when performing JJIJ machining of long pipes, there is the advantage of being able to perform all machining by inputting data once. For this reason, there is no need to divide data each time and perform corrections due to division as in the conventional method, so there is a favorable N characteristic that productivity is further improved.
