Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a framing device for framing four fragments in a rectangular shape using corner pieces and provided with slots.

Conventionally, when corner pieces are used to frame four fragments with drawn grooves into a rectangular shape,
First, two pieces are butted together to form the corners of a rectangular frame.
At the end of the book frame piece, temporarily fit a corner piece into the fitting groove of the broken piece to form a square temporary frame, and then use a hammer cylinder to drive the corner piece into the fitting groove of the frame piece to form a square frame. ing.

Therefore, with such a framing method, workability is poor, and in addition, the frame pieces are framed at the corners of the rectangular frame without being brought into close contact and accurately butted together, resulting in an undesirable non-uniform product. .

In addition, conventional framing equipment is used to frame this type of framework, i.e., four frame pieces cut to a predetermined length from a profile with inset grooves on both side edges of the web, into a rectangular shape. If so, since the pieces are made of shapes, when the corner pieces are press-fitted into the fitting grooves of the frame pieces that are assembled together, the frame pieces buckle and the corner pieces are bent. Compared to a wooden frame frame, the frame pieces cannot be accurately butted together at the four corners of the frame, and the frame product will also be uneven.

An object of the present invention is to cut four frame pieces to a predetermined length from a profile having fitting grooves on both side edges of the web to corner and
This improves the workability of the framework by using pieces, and in particular, prevents the frame pieces from buckling in the direction of buckling, and allows the corner pieces to fit into the grooves. Enables accurate press-fitting, brings frame pieces into close contact at the four corners of a rectangular frame, butts them together accurately, and fixes the frame piece and its corner piece in that tight state without using screws or rivets. Our goal is to provide framework equipment for obtaining uniform framework products.

With these issues in mind, the framework device of this invention first of all,
Four fragments cut to a predetermined length from a profile with fitting grooves on both sides of the web are arranged in a square shape, and corners with stopper holes are placed in the fitting grooves of the pieces that are combined with each other at the four corners. - A table on which a rectangular temporary frame is placed, in which the pieces are temporarily fitted and temporarily framed, and placed on the table in the diagonal direction of the temporary frame so as to receive the inside of the four corners of the temporary frame, and , the tip of the right-angled ■-shaped bone is located outside the four corners of the temporary frame at an appropriate distance from the corresponding inner block in the diagonal direction of the four inner blocks with faces and the corresponding inner block. Moreover, it is capable of reciprocating toward the inner block, is placed on the table, is provided with a right-angled ■-shaped press opening at the tip, and is further provided with a bore located in the diagonal direction of the temporary frame. It has four outer blocks, a right-angled V-shaped pressing surface at the tip, and a pair of knobs on the pressing surface to be fitted into the bores of the corresponding outer blocks, with a press pad interposed therebetween. It includes four presses reciprocably connected to the outer block by guide bolts, and a hydraulic pressure operating cylinder for the outer block connected to the outer blocks and the press. Drive the operating cylinder to press the outer block and the press against their corresponding inner blocks in conjunction with each other, press the corner pieces into the fitting grooves of the combined pieces, and then press the press into its corresponding inner block. It is pressed against the inner block, and a part of the frame piece is injected into the stopper hole while being deformed, so that the broken pieces are connected to each other to the rectangular frame.
