Abstract

PURPOSE:To perform location of a process head automatically and accurately using an inner end face of a flange as a reference by providing a detection means so as to detect the inner end face of the flange along its width direction, on the front part of the other process head, as well as on the corresponding position, and by controlling a driving member of an interval adjusting means by this detected signal. CONSTITUTION:By normal rotation of a reversible motor Mb, the other process head Bb, along with detection switches Lb and Ls, moves in a direction where the interval is closed. Owing to this movement, outer end of the other flange (b) in a work or H-steel (W) is detected by the detection switchs Lb, Ls. Through the closing actuation of interval, a third detection switch Ls reaches the position of an inner end face (m) of the flange (b), and when this is detected, normal rotation of the reversible motor Mb is stopped by the detected signal. The interval between a fixed process head Ba and a moving process head Bb can thus be automatically set according to the width of the work (W).

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a groove scalloping process in which the interval between a pair of processing heads is automatically set to a predetermined position before feeding the 11 section steel to the processing position. This invention relates to a machine head spacing adjustment device.

(Prior Art) For example, when a section steel is used in a steel frame joint, beveling and scalloping are performed on the joint for the purpose of improving welding quality and improving workability.

In short, as shown in Fig. 10, notches Fa and Fb (scalloped) are formed in the solid joint between the flanges a and b on both sides of the H-shaped steel W and the web C, and the deep portions are arcuate. Straight root surface Ra at the ends of flanges a and b
, Rb and sloped chamfered surfaces Va, Vb (bevel processing).
A double-head type beveling machine described in No. 4 is known.

This conventional beveling machine has a pair of left and right machining heads, and this machining head includes a clamping means for clamping both flanges of the H-section steel from the top and bottom, and a required beveling and scalloping process on the end. It is equipped with cutting means for processing.

In this processing machine, before introducing the workpiece, it is necessary to adjust the distance between the pair of processing heads in the left-right direction, that is, in the width direction of the H-section steel, and to set an appropriate ramp position and cutting position.

The spacing adjustment for this purpose is performed by setting one processing head on a fixed side and setting the other processing head on a moving side, by associating a feed screw type drive means with this moving side.

(Problems to be Solved by the Invention) In the conventional processing apparatus, as shown in the explanatory diagram of FIG. A cylindrical drive-in cutter 36 and a conical bevel cutter 38 are responsible for this, respectively, and the positions of these cutting heads are set based on the inner end surfaces of flanges a and b (indicated by m and m in the figure). ing.

Therefore, to set this interval, measure the width (inside dimensions of both flanges) of the H-shaped steel supplied to the processing head in advance, and based on this measurement, for example, operate a button switch according to the display scale to activate the drive means. However, this poses a problem in that the adjustment takes time and effort, and also causes other problems such as poor processing and damage to the machine due to measurement errors or setting errors.

In order to solve the above problems, a system has been developed in which the spacing is adjusted by NC control and the width of the workpiece is adjusted by program operation, but even with this, there is still a problem that manual settings are required. However, since the problem had not been solved yet and the manufacturing cost was soaring, it was impossible to incorporate it into general-purpose machines.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a head spacing adjustment device that can automatically set the spacing with a simple configuration.

(Means for Solving the Problems) In order to achieve the above object, a head interval adjustment device for a bevel scalloping machine of the present invention is configured as follows.

That is, the gist of the present invention is to provide a pair of machining heads on both sides equipped with a cutting means, a clamping means, etc. at the tip of an H-shaped steel that is transferred in the longitudinal direction, and to attach a pair of machining heads on both sides, each of which is equipped with a cutting means, a clamping means, etc. A back and forth adjustment means for adjusting the corresponding position in the longitudinal direction is provided on one side, and a distance adjustment means for adjusting the corresponding position in the width direction of the H-beam is provided on the other machining head side. In a processing machine that performs the required beveling and scallop processing on the flange end and the joint ends of both side flanges and webs, a detection device that detects the inner end surface in the width direction of the flange in front of the other processing head and at a corresponding position. A means is provided, and the driving member of the distance adjusting means is controlled by the inner end surface detection signal of the detecting means.

(Function) The H-shaped steel, which is the workpiece, is being transferred in the longitudinal direction, and one flange corresponds to one machining head, so this position can be used as the reference side when adjusting the interval. can. Corresponding to this one flange side is one machining head that is fixed in the spacing adjustment direction.

When the drive member is driven in the forward or reverse direction, the detection means moves in the predetermined interval adjustment direction together with the other processing head. As a result of this movement, when the detection means detects the inner end surface in the width direction of the other flange, the drive member is stopped in response to a detection signal, and the other processing head is positioned. Therefore, when installing the detection means, by arranging the position, the cutting position of the processing head, and the clamp position in relation to each other, the processing head can be set at an appropriate position according to the width dimension of the workpiece. It comes.

The above detection means recognizes the inner end surface of the flange in the workpiece material by the operation of "no material" → "material" → "no material" or "no material" → "material", and uses the detection signal to determine the interval. The driving member of the adjusting means is controlled to stop.

This ruler means is provided on both processing heads in correspondence with the flanges a and b on both sides, and is symmetrical. Therefore, only one of them will be explained here. However, each contact detection switch Sc
, Sd, only their locations are shown in FIGS. 1 and 2.

In other words, 79 is the head to gauge 12 in the cutting means.

Therefore, when the workpiece W is transferred and the flanges a and b come into contact with the contact piece 86, the horizontal support shaft 84 rotates via the rotation arm 85, and the contact detection switch Sc or Sd is activated by the actuation piece (not shown). outputs a detection signal. The rotation range of the rotation arm 85 after this detection is regulated by a stopper member (not shown), and the rotation arm 85 contacts the workpiece W at the regulated position to set the position.

The contact detection switches Sc and Sd operate the drive motor Mc of the conveying means A and the longitudinal adjustment means E according to their detection signals.
The control circuit controls the rotation of the reversible motor Ma and sets the feeding position of the workpiece W, and the following control circuit is configured.

That is, in FIG. 9, when the processing head interval setting end signal is input, the normal rotation circuit p1 of the drive motor is closed, the normal rotation magnet coil MC-2F is excited, and the drive motor Mc rotates in the normal direction. When one detection switch Sc detects the preceding flange a end due to the transfer of the workpiece W, the forward rotation circuit 12 of the reversible motor is closed, the forward rotation magnet coil MC-IF is energized, and the reversible motor Ma rotates forward. .

Due to the transfer of the workpiece W and the rearward movement of one support frame 9, the other detection switch Sd is moved to the trailing flange!
] is detected, the normal rotation circuit 1! , J12 are both opened, and both motors Mc and Ma are stopped.

Further, when the drive motor Mc rotates forward and the other detection switch Sd first detects the trailing flange b while the workpiece W is being transferred, the forward rotation circuit ll of the drive motor is opened and the motor Mc Stop.

Subsequently, the reversing circuit 13 of the reversible motor Ma is closed, the reversing magnet coil MC-IR is excited, and the reversible motor M

An embodiment of the head spacing adjustment device for a bevel scalloping machine according to the present invention is as described above, and operates as follows to set an appropriate machining head spacing corresponding to workpieces of various widths. I'll come.

That is, when the workpiece W is put into the conveyance means A'2 and transferred to the rear, that is, to the processing head side while one flange a is regulated by the kite means J, the first detection switch La first detects the tip of the workpiece W. The detection signal causes the drive motor Mc of the conveying means A to stop. By stopping the drive motor Mc, the workpiece W is stopped at the width measurement position on the conveyance means.

In this state, if the widthwise positions of the second and third detection switches Lb and LS are wider than the width of the workpiece W, in the control circuit of FIG. 8, the reversible motor Mb
By closing the normal rotation circuit 1a, the normal rotation magnet coil M
C-1 is excited and the reversible motor Mb rotates forward. The forward rotation of the reversible motor moves the other processing head together with the detection switches Lb and LS in the direction of closing the gap, and this movement causes the second and third detection switches Lb and LS to move in the direction of closing the gap.
LS is the outer end of the flange b on the workpiece W, that is, "
Detects the state of “no wood” → “wood”. This detection signal causes relay coil CR-2 of relay circuit 11) to
or excite and self-hold. Then, due to the closing operation of the interval, the third detection switch LS reaches the position of the inner end surface m of the flange l], and the contact is switched.
When the transition from "with material" to "without material" is detected, the relay circuit IC is closed and the relay coil CR-2 is energized. Therefore, the relay contact CR-2b in the normal rotation circuit pa is opened, and the rotation of the reversible motor Mb is stopped.

At this time, the position is specified by moving or stopping the other machining spatula I~ in the opening direction, and the clamping means D and cutting means Bb of the other machining head are located at this position or at the end of the other flange b. The position corresponds accurately to the flange inner end surface m as a reference.

Furthermore, when the workpiece W is supplied to the measurement position, the second and third detection switches LI], LS
When the widthwise position of 1. is closed, the second detection switch 1. of these detection switches is closed. 1 available material for B or work W.
is detected and operates to close the reversing circuit 1d of the reversible motor Mb in the control circuit.

At this time, the reversible magnet coil MC-2 is excited and the reversible motor Mb is reversed. By reversing the reversible motor,
The other processing head moves in the direction of opening the gap together with the detection switches Lb and LS, and during this movement, the third detection switch LS moves from the inner end surface of the flange b of the workpiece W, that is, from "no material J" to "material material J". ” is detected. This detection signal causes the switch contact LS- in the reversing circuit ld to
b opens, and reversible motor Mb stops rotating.

Therefore, at this position, the movement of the other machining head in the opening direction is stopped, and the clamping means D and the cutting means Bb are set to coincide with each other at the end of the other flange b.

Note that when feeding the workpiece W to the measurement position, the flange b
When the third detection switch LS is contacted, the reversing circuit ρd is closed and the interval is temporarily opened, after which the above-mentioned interval adjustment operation is performed.

As described above, with this control means, even if the width of the workpiece W is wider or narrower than the existing head spacing, the detection switch operates accurately to adjust the head movement appropriately. I can do it.

After adjusting the positions of both machining heads to the width of the workpiece W as described above, if the conveying means A is driven to further feed the workpiece W toward the machining head side, both flanges a and b on the workpiece can be moved. Contact pieces 85 of ruler means Ga, Gb.
85, it is possible to adjust the machining head back and forth according to the tip shape (gradient condition) of the workpiece.
In addition, subsequent work clamping operations, cutting operations, and a series of other operations can be performed smoothly.

In addition, in the above, if the width of the workpiece W is larger than the existing processing head spacing, the spacing between the processing spatulas l will increase,
The third detection switch LS is controlled to stop its releasing operation by the operation of "No material J-" and "Medium". However, the U-turn control takes about 2 days - that is, the processing head is moved from the above-mentioned stop position to the open side, and then moved to the close direction, and the third detection switch is set to "material available" → If the machining head is finally stopped when performing the "no material" operation, the head spacing can always be set in the closing direction, allowing more accurate positioning. This U-turn control method can be incorporated into a control circuit and employed as appropriate.

Further, in one embodiment, both the first detection switch and the second detection switch are of a non-contact type, or they may of course be of a contact type such as a limit switch. Further, as the third detection switch, a so-called non-contact type switch such as a proximity switch can be adopted. Further, as the driving member of the distance adjusting means, not only a motor but also a hydraulic cylinder whose position can be controlled can be used as appropriate.

Further, in one embodiment, the interval adjustment is performed in both the opening and closing directions. However, 2. If the other processing head is always on standby at the open end or closed end and the interval is set in either the open or close direction, the second detection switch is not necessary and can be deleted. .

(Effects of the Invention) As described above, the head spacing adjustment device for a bevel scalloping machine of the present invention has a simple configuration, and automatically adjusts spatula to spacing settings according to the width of section 11 steel. It has great effects in that it can be done accurately.

In addition, there is no human intervention in the setting process, so
Processing defects caused by conventional measurement errors and setting errors,
It has the feature of not causing any damage to the machine. In particular, since the position of the processing head can be set with reference to the inner end surface of the flange, a series of operations such as clamping operation and cutting operation can be performed smoothly.
