Description

Technical Field

[0001] The invention relates to the technical field of assembled interior ceiling decoration, and in particular to a ceiling "X" keel cutting and bending tool and a use method thereof. Background Art

[0002] When installing the assembled ceiling, the "J" keel is buckled through the base and connected to the ceiling board through locking screws. After the installation, the entire ceiling board is lifted above the ceiling edge strip. When installing the existing assembled ceiling, in order to avoid interference with the edge strip, the "J" keel needs to be shorter than the ceiling board. In order to make the "J" keel rest on the edge strip, the current processing method is to add a wood plastic block in the middle of the "J" keel, and connect the wood plastic block to the "J" keel through locking screws on both sides. In the actual installation process, the step of locking the wood plastic block on the "J" keel is relatively cumbersome. It is found that the size of the wood plastic block and the size after installation will affect the installation of the ceiling board. The wood plastic block cannot be placed just on the edge strip, so that the ceiling board remains flat, and the fire protection level of the wood plastic block is very low, which does not meet the A-level fire protection requirements.

[0003] Chinese patent CN205296533U, published on 2016-06-08, discloses a novel vertical sheet ceiling, wherein the light keel hanger is nested on the light keel, the hanger rod is connected to the light keel through the light keel hanger, and also includes a "J" keel and a "J" keel hanger, the "J" keel hanger is nested on the light keel, the "J" keel is connected to the light keel through the "J" keel hanger, the "J" keel sides are respectively provided with cards and windproof pressure sheets, and the ceiling is fixed under the "J" keel through the cards and windproof pressure sheets. The "J" keel designed in this application is in a "J" structure, which can solve the problems that the existing aluminum alloy ceiling does not have an open field of vision, poor ventilation, poor air permeability, unclear overall lines, unclear layers, and cannot reflect a simple and clear modern style; and the "J" keel of this application is provided with a card slot, a card and a windproof pressure sheet for easy installation and disassembly. When installing the suspended ceiling of the above-mentioned patent, the "J" keel needs to be shorter than the ceiling board in order not to interfere with the edge strip. In order to make the "J" keel rest on the edge strip, the wood plastic block is connected to the "J" keel by locking screws on both sides. The step of locking the wood plastic block on the "J" keel is relatively cumbersome. It is found during the installation that the size of the wood plastic block and the size after installation will affect the installation of the ceiling board. The wood plastic block cannot be just placed on the edge strip to keep the ceiling board flat. Summary of the invention

[0004] The purpose of the present invention is to provide a ceiling ""-shaped keel cutting and bending tool and a method of using the same in view of the above-mentioned deficiencies in the prior art.

[0005] The present invention provides a ceiling ""-shaped" keel cutting and bending tool, which is used for cutting and bending the ""-shaped" keel, comprising a bottom plate, a bottom clamping piece fixed to one end of the bottom plate, a bottom lifting and pressing piece connected to the other end of the bottom plate and one side end of the bottom clamping piece, a bending piece used for sleeved on the ""-shaped" keel when one end of the ""-shaped" keel is sleeved on the bottom clamping piece and the bottom lifting and pressing piece in sequence, a bottom edge shearing piece used for cutting the extension plate of the ""-shaped" keel, and a bottom edge shearing piece used for cutting the extension plate of the ""-shaped" keel and the side plate of the ""-shaped" keel and the side plate of the ""-shaped" keel. The portion connected at the cutting point of the extension plate is cut to form a side shearing piece of the shear plate on the "I" keel. After the bottom shearing piece cuts the extension plate and the side shearing piece cuts the side plate, the bending piece moves in a direction away from the "I" keel to a first preset position. When the bending piece moves to the first preset position, the bottom lifting and pressing piece drives one end of the "I" keel to move in a direction away from the bottom plate so that one end of the "I" keel abuts against the bending piece to bend the shear plate to form a bent plate.

[0006] Furthermore, the bottom clamping member includes a first base plate fixed on the bottom plate, a first mounting block arranged in the middle of the first base plate, a first cutting groove arranged on the first base plate, and a second cutting groove arranged on the side of the first mounting block, the first cutting groove and the second cutting groove are connected, and the length of the first cutting groove is greater than or equal to the width of the extension plate of the "I" keel.

[0007] Furthermore, the center line of the first mounting block coincides with the center line of the first substrate, the first cutting grooves are two symmetrically arranged on the parts of the first substrate located on both sides of the first mounting block, and the second cutting grooves are two symmetrically arranged on two opposite sides of the first mounting block.

[0008] Furthermore, the bottom clamping member also includes a first card slot arranged at one end of the first mounting block, and the bottom lifting and pressing member includes a second substrate, a second mounting block arranged in the middle of the second substrate, a first card block arranged at one end of the second mounting block and used for being clamped in the first card slot, and a stop plate arranged at the other end of the second mounting block and used for stopping the I-shaped keel when one end of the I-shaped keel is sequentially sleeved on the first mounting block and the second mounting block.

[0009] Furthermore, the bottom edge shearing piece includes a third substrate and a first cutting knife disposed at the bottom end of the third substrate for cutting.

[0010] Furthermore, the first cutting knives are two symmetrically arranged about the center line of the third substrate, the first cutting knives are perpendicular to the first cutting groove, the length of the first cutting knife is greater than or equal to the distance from the top of the first mounting block to the bottom of the first cutting groove, and the distance between the two first cutting knives is greater than or equal to the sum of the thicknesses of the first mounting block and the two side plates of the "J" keel.

[0011] Furthermore, the side shearing piece includes a fourth substrate and a second cutting knife disposed at one end of the fourth substrate for cutting.

[0012] Furthermore, the bending part includes a socket block which is used to be sequentially socketed on the bottom clamping part at one end of the "I" keel and socketed on the "I" keel when the bottom is lifted and pressed, and an extrusion plate which is arranged at the bottom end of the socket block and is used to press the extension plate of the "I" keel when the socket block is socketed on the "I" keel, and the length of the extrusion plate is less than the distance between the stop plate and the first cutting groove.

[0013] Furthermore, the bottom plate is provided with a first fixing hole, the first base plate is provided with a second fixing hole, and the bottom clamping member further comprises a fastening structure with one end passing through the second fixing hole in sequence and being fixed to the first fixing hole.

[0014] A method for using a ceiling "X" keel cutting and bending tool comprises the following steps:

[0015] S1: Fix the bottom clamp to one end of the bottom plate;

[0016] S2: Fix the bottom lifting and pressing member to one end of the bottom clamping member;

[0017] S3: The ""-shaped" keel is sleeved on the bottom clamping part and the bottom lifting and pressing part in sequence, and the bending part is sleeved on one end of the ""-shaped" keel;

[0018] S4: Cutting the extension plate of the "I" keel by the bottom shearing piece and cutting the side plate of the "I" keel by the side shearing piece to form a shear plate on the "I" keel;

[0019] S5: Move the bending piece in a direction away from the "I" keel to a first preset position. When the bending piece moves to the first preset position, the bottom lifting and pressing piece drives one end of the "I" keel to move in a direction away from the bottom plate so that one end of the "I" keel abuts against the bending piece to bend the shear plate to form a bent plate.

[0020] The ceiling "X" keel cutting and bending tool and the use method thereof of the present invention have the following beneficial effects:

[0021] 1. One end of the bottom clamp is fixed to one end of the bottom plate, one end of the bottom lifting clamp is connected to the bottom clamp to improve the stability of the supporting keel. The bending piece is sleeved on the keel, thereby stopping the keel in the vertical direction to prevent the keel from falling off the bottom clamp. The bottom shearing piece cuts the extension plate of the keel, and the side shearing piece cuts the part of the side plate of the keel connected to the cutting part of the extension plate to form a shear plate on the keel, thereby completing the extension plate and side plate of the keel. The cutting, the bending piece moves in a direction away from the "J" keel to a first preset position, thereby limiting the "J" keel, and the bottom lifting and pressing piece drives one end of the "J" keel to move in a direction away from the bottom plate so that one end of the "J" keel abuts against the bending piece to bend the shear plate to form a bent plate, thereby respectively cutting the preset positions on the extension plate at the bottom end of the "J" keel and the side plate to form a shear plate, and vertically pressing the shear plate upward to form a bent plate, completing the bending of the "J" keel, with high work efficiency, wide application range, and simple operation;

[0022] 2. The first substrate is fixed to the bottom plate to improve the stability of the bottom clamping piece. The extension plate of the "J" keel is cut along the first cutting groove, and the side plate of the "J" keel is cut along the second cutting groove, so that the shear plate is cut on the "J" keel. The length of the first cutting groove is greater than or equal to the width of the extension plate of the "J" keel, so that when the "J" keel is sleeved on the bottom clamping piece, the extension plate does not completely cover the first cutting groove, so that the extension plate is cut along the uncovered part of the first cutting groove. The first cutting groove and the second cutting groove are connected, so the side plate of the "J" keel can be cut along the cutting position of the extension plate, which is more efficient.

[0023] 3. The first clamping block is clamped in the first clamping groove to improve the stability of the connection between the bottom lifting and pressing member and the bottom clamping member, and the installation is simple. The stop plate can prevent the "J" keel from passing through the second mounting block when it is sleeved on the second mounting block, which is convenient for cutting;

[0024] 4. The two first cutting knives respectively cut the two extension plates of the ""-shaped" keel along the two first cutting grooves to form incisions on the extension plates. The length of the first cutting knives is greater than or equal to the distance from the top of the first mounting block to the bottom of the first cutting groove, so that when the first cutting knives move toward the direction close to the bottom of the first cutting groove, the first cutting knives can cut the extension plates and pass through the extension plates, thereby improving the effect of cutting the extension plates;

[0025] 5. The sleeve block is sleeved on the "J" keel. After the bottom shearing piece completes cutting the extension plate and the side shearing piece completes cutting the side plate to form the shear plate, the sleeve block moves in the direction away from the extension plate until it is flush with the top of the shear position on the side plate, and the bottom lifting and pressing piece moves in the direction away from the extension plate to drive the shear plate to abut against the extrusion plate, so that the bottom lifting and pressing piece and the extrusion plate respectively apply pressure to the upper and lower ends of the shear plate to squeeze the shear plate, thereby squeezing the shear plate to form a bent plate.
