Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for feeding a material to be cut, such as a long round steel, pipe material, or shape material, to a cutting machine at a fixed length. The present invention relates to a device for transferring a predetermined cutting length at a time.

(Prior Art and its Problems) Conventionally, in this type of device, in order to set the transfer length of the material to be cut, that is, the cutting length, a cart is provided that moves between the rear of the cutting machine and the cutting machine. At the same time, a cutting length setting mechanism consisting of a threaded shaft is installed in the front of the cutting machine, and the material to be cut is clamped and fixed by a clamping means installed on the cart and transferred forward, while the tip of the material to be cut is moved forward. According to this, the cutting length is set by the distance between the abutting member and the cutting position by making the abutting member move integrally with the above-mentioned screw shaft. Since the cutting length setting mechanism exists in the front of the cutting machine, extra space is required, which not only increases the size of the entire device, but also requires separate cutting shafts for each cutting length when there are multiple cutting lengths. There was a problem in that changing the cutting length required time and effort because the scale plate had to be rotated while looking at it.

(Technical Problem of the Present Invention) The technical problem of the present invention is to make the device as compact as possible so as not to take up extra space, and also to make it possible to set the cutting length for each cutting length when there are multiple types of cutting lengths. The goal is to make it easy to do.

Next, the operation of the sizing material feeding device having the above-described configuration will be explained.

First, the disk body 12 is rotated by the rotation operation mechanism 15, and desired seven of the three cut material feed start position setting stopper pieces 13A, 13B, and 13C on the disk body 12 are moved to the carriage. It is set in a position coaxially facing the abutment piece 10 of No. 6. In addition, these stopper pieces 13A, 13
B and 13C have protrusion lengths predetermined according to the three types of cutting lengths for the material to be cut B, and the stopper piece 13A has a protrusion length that is the shortest of the three types of cutting lengths. The stopper piece 13C is for setting the feed start position of the material to be cut, and the stopper piece 13C is for the longest cutting length, and the stopper piece 13B is for the intermediate cutting length. After setting the feed start position of the material to be cut, the piston rod 7a of the hydraulic cylinder 7, which is the drive mechanism, is
By the contraction operation, the cart 6 is moved back toward the fixed base 4 side, and the impact piece 10 is moved to the stopper piece for setting the starting position for feeding the material to be cut (
13A), thereby stopping the carriage 6 at the feed start position.

At this stop position, the clamp mechanism 8 is activated,
Required portions of the material to be cut B supplied onto the cart 6 are held. Then, when the piston rod 7a of the hydraulic cylinder 7 is extended and the truck 6 is moved forward, the abutment piece 9 at the front end of the truck 6 hits the stopper piece 11 for regulating the end position of cutting material feed on the cutting machine A side. At this point, the device stops, and at this stop position, the vise device 3 is operated to clamp and fix the part of the workpiece B sent to the cutting machine A side in front of the cutting position, and the cutter 2 cuts the workpiece B. Cut the tip of B. After that, 1, while the workpiece B is still fixed on the cutting machine A side by the vise device 3, the piston rod 7a of the hydraulic cylinder 7 is contracted to move the cart 6 back to the workpiece feeding start position, and then the vise Open device 3. Thereafter, by repeating the above-described series of operations, the material to be cut B is transferred to a certain length (the stopper piece 13A is indicated by LA in FIG. 2) and cut into this length.

When changing the cutting length of the material to be cut B to another cutting length, the disc body 12 is again rotated by the rotation operation mechanism 15 to obtain a cut length corresponding to the required cutting length. A stopper piece (for example, 13B or 13C) for setting the cutting material feed start position may be placed at a position coaxially opposite to the abutment piece 13.

In the above-mentioned sizing material feeding device, the stopper piece 11 for regulating the end position of the material to be cut can extend and contract its protruding length, thereby adjusting the feeding length of the material to be cut B, that is, the cutting length as appropriate. I'm trying to make it possible. Further, although not shown in the drawings, detecting means such as a gauge limit switch are provided at appropriate locations to confirm whether the cart 6 is at the feed start position of the material to be cut or the feed end position.

(Effects of the Invention) The sizing material feeding device of the present invention has a guide frame extending parallel to the feeding direction of the material to be cut interposed between the fixed base and the cutting machine, and the guide frame is interlocked with a drive mechanism. The cart is movably supported, and this cart is equipped with a clamp mechanism capable of clamping and releasing the material to be cut, and an abutment piece is provided at the end of the cart on the cutting machine side and the end on the fixed base side, respectively. A stopper piece for regulating the feed end position of the material to be cut is provided at the end of the cart side of the cutting machine at a position coaxially opposite to the abutment piece on the cutting machine side, and a stopper piece for regulating the end position of feeding of the cut material is provided at the end of the cart side of the fixed base. A disc body consisting of a plurality of stopper pieces for setting the feed start position of the cut material that protrudes in the feed direction of the cut material and each having a different protrusion length is disposed in the circumferential direction of the front surface is rotatably pivoted via a rotary operation mechanism. The fixed base side abutment piece coaxially faces a required stopper piece for setting the feed start position at a required rotational position of the disk body, and the entire device Because they are concentrated only on the rear side of the cutting machine, they do not take up extra space and can be made compact, and when cutting multiple lengths, the disk body can be rotated as appropriate. This has the effect of allowing the cutting length to be changed extremely easily and quickly just by doing so.
