Abstract

PURPOSE:To improve the accuracy in edge working and reduce the loss time for mounting and demounting a long steel plate by installing a guide roller in projection onto the upper and lower guide rails on the both sides of a transfer table for the long steel plate and installing a magnet in screwing ways onto a magnet holder installed in series. CONSTITUTION:A power package 34 for raising and lowering a magnet is installed onto a transfer table, and pressurized oil is supplied into the hydraulic cylinder 47 of a magnet raising and lowering apparatus 31, and the package 34 is press-attached onto a steel plate P on a steel-plate transfer level surface by a raising and lowering coil spring 39. When the grinding work and carrying-out of the steel plate P which is attracted by exciting the magnet 30 are completed, the excitation for the magnet 30 is cut-off, and the magnet 30 is lowered, overwhelming the rising force of the magnet 30, and the transfer table 5 is retreated free from the contact of the magnet 30 with the steel plate. Therefore, the steel plate can be mounted and demounted from the transfer table, and the loss time for the fixation and release on transfer can be economized. Further, the accuracy can be improved by the straight guide of the transfer table 5 in the combination of a guide roller and a table guide as a transportation and guide means.

Description

Detailed Description of the Invention (Objective of the Invention) The present invention is directed to the processing of a steel plate, which is a long heavy steel plate, in bevel milling or grinding of the edge of a steel plate, which is a pre-process of @joint #14 pipe processing. This invention relates to a copper plate conveying device that can be placed on a conveying roller table, carried in, cut, and carried out.

(Prior Art) In conventional beveling milling or grinding of the edge of a steel plate, a long and heavy copper plate is placed on a roller table and transported to a processing device, but TL! For J#Il processing, a method is used in which a milling blade or grinding head is mounted firmly on a gate-type traveling cart or mount to perform the cutting feed process. There was also a method of processing by moving the fixed piece on the top, but in either case, the sheet on the conveyor roller table was carried into the edge of the table, and the core of the table was moved. I + l IJ that can automate the operation of moving the clear urine straight ahead, setting up one plate at the end of cutting 4, and retracting the feeding table at the same time.
The transport table guide system and the device for attaching and detaching a single plate to and from the transport table had not been developed, which caused problems in processing operations.

(Configuration 1 of 9d-ro) This invention solves the above problems and carries a conveying roller table into a processing device for cutting and grinding long heavy objects, performs processing feed, and then carries out the steel plate. This is a steel plate carrying-in device (d) that can be used to carry in the next lot of copper plates by retracting the conveying table.

The basic structure is a conveyance roller table installed in a copper plate edge milling or grinding device, and square strips are installed horizontally on both sides of the conveyance table, and the guide rails come in contact with the outside and top and bottom edges of the guide rails to guide the transfer. A conveyance table guide device consists of a pair of table guides on both sides with protruding guide rollers installed horizontally in series in the conveyance direction, and a magnet is screwed onto a magnet holder installed in series on the conveyance table to adjust the conveyance. The apparatus has a device for attaching and detaching the steel plate to and from the conveyance table, which drives a magnet lifting and lowering device that can lower the magnet holder when processing and conveyance of the steel plate is completed, attaches the magnet from the steel plate, and retracts the conveyance table.

(2) When processing and transporting steel plates, a magnet and a magnetic lifting device are installed as a device that can automatically attach or detach the steel plate to the conveyance table, and the steel plate can be attached to and detached from the conveyance table at will, and it can be used to fix and release the AQ plate during conveyance. In addition, the productivity of the processing equipment can be improved because the next lot of steel plates can be carried in by retracting the magnets installed on the transfer table without coming into contact with the processed steel plates. Furthermore, since the rack and pinion drive device attached to the conveyance table can be switched between cutting feed and conveyance in two stages, it can be used to further improve productivity.
