Problems solved by technology

[0007] Although the stair slabs prepared above solve the problems of raw material loss and the strength of the stair slabs, the types of flame-retardant boards used are relatively single. Nowadays, home decoration often requires the stair boards to be consistent with the style of the entire room. Stair boards made of flame-retardant boards There are very large limitations in appearance; in addition, when pressing the flame-retardant board, it is first pressed on the upper surface for 24 hours, and then the flame-retardant board is bent for 12 hours with a bending machine to fit the arc-shaped side of the first preparation board. If it is necessary to press the flame-retardant board on the arc-shaped side and the lower surface of the extension, the whole pressing process is complicated and takes a very long time

Embodiment 1

[0066] (Example 1, the stair strip plate with corner settlement)

[0067] See Figure 9 , the stair strip plate material with corner settlement in this embodiment includes a base plate 7 and a veneer paper layer 6 pressed and fixed on the base plate 7. The base plate 7 is an integral component, which is parallel to each other in the front and rear directions and vertically arranged along the left and right directions All cross-sections have the same shape. The overlay paper layer 6 includes an impregnated paper layer 61 and a wear-resistant paper layer 62 .

[0068]The substrate 7 is composed of a head 71, a main body 72 and an extension 73 connected in sequence from left to right, and the head 71 is composed of a round head 71-1 and a connecting part 71-2 connected left and right. The outer peripheral side of the round head 71-1 is an arc-shaped curved surface that protrudes to the left, and the shape of the cross-section vertically arranged along the left and right directi...

Embodiment 2

[0073] (Example 2, the processing mold and preparation method of the stair strip plate with corner settlement)

[0074] See figure 1 , The processing mold of the stair bar plate in this embodiment includes an upper mold 1 , a lower mold 2 , a spring pressing sheet mold 3 and an elastic member 4 . Both the upper mold 1 and the lower mold 2 are made of No. 45 mold steel, and the lengths of the upper mold 1 and the lower mold 2 are both 2500mm. In this embodiment, the elastic member 4 is a cylindrical compression spring.

[0075] See figure 2 , the upper mold 1 is provided with a mold cavity with an opening towards the lower left, the surface of the mold cavity is a polished surface, and the surface of the mold cavity consists of a first arc surface 11, a first plane 12 and a second arc The shape surface 13 is connected successively from the upper left to the lower right and forms a smooth transition, and the shape of each section of the surface of the mold cavity in the fron...

Embodiment 3

[0110] (Example 3, the processing mold and preparation method of the stair strip plate with corner settlement)

[0111] See Figure 11 , the remaining part of the processing mold of the stair bar plate of the present embodiment is the same as that of Embodiment 1, the difference is that: the depth of the installation groove 25 of the lower mold 2 is relatively shallow, and the installation groove 25 is arranged sequentially on a straight line along the front and rear Cuboid blind hole. The elastic component 4 disposed in the installation groove 25 is a leaf spring, and the depth of the installation groove 25 is greater than the thickness of the leaf spring 4 . The lower end of the leaf spring 4 is fixed on the lower end of the installation groove 25 by welding or riveting, and the upper end of the leaf spring 4 is located outside the third plane 22 when no external force is applied, and can be pressed below the third plane 22 when subjected to an external force.

Abstract

The invention discloses a stair strip sheet material with settled corners and a mold and a method for processing the stair strip sheet material. The stair strip sheet material comprises a base plate and a sticking paper layer which is pressed against and fixed on the base plate, wherein the base plate comprises a head part, a main body part and an extension part, which are sequentially connected in an order from left to right; the head part consists of a circular head part and a connection part in left-right connection; the whole sticking paper layer is continuously distributed at the peripheral side of a corner settlement part of the main body part of the base plate, on an upper plane of the main body part, and at the peripheral side of the head part; the peripheral side of the head part comprises the upper plane of the connection part, the peripheral side of the circular head part and a lower plane of the connection part; and the upper plane of the connection part, the peripheral of the circular head part and the lower plane of the connection part are sequentially connected. By the invention, hot-pressing of sticking paper on the head part of the base plate of the stair strip sheet material, an upper surface of the main body part and the peripheral side of the corner settlement part can be realized in a one-time pressing process, so that production efficiency is greatly improved, and the sticking paper which is pressed against the stair strip sheet material is smooth, continuous, and elegant in appearance.

Description

technical field [0001] The invention relates to a stair bar plate, a manufacturing method and a processing mold thereof. Background technique [0002] Chinese patent document CN101804648 A (Application No. 201010134936.5) discloses a method for manufacturing a composite panel with a side round head wrapping angle, a processing mold and the composite panel, and mentions stair treads and its manufacturing mold and method. The stair treads include a round head on the right side and a board body with a rectangular cross-section on the left side. The central angle of the round head is at most 175 degrees. The lower left part of the round head also includes a cutting formed Rectangular gap, the lower end surface of the left part of the round head and the lower end surface of the right part of the plate main body are located in the same plane; the right side of the upper end surface of the plate main body is tangent to the upper left side of the arc cylinder of the round head, The...
