Description

Technical Field

[0001] The utility model relates to a bending die, in particular to a bending die for preventing sticking and separation of a section steel, belonging to the technical field of bending processing equipment. Background Art

[0002] Steel is a strip steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, tube, profile, wire). According to the cross-sectional shape, steel is divided into simple cross-sectional steel and complex cross-sectional steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channel steel, rails, window frame steel, curved steel, etc. The bending machine mold is a tool used by the bending machine to form and process sheet materials. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the formed material. It is used to make the blank into a tool with a specific shape and size under the action of the bending machine pressure. The bending machine mold is divided into a bending machine upper mold and a lower mold, which are used for sheet metal stamping and separation. The forming mold has a cavity, and the separation mold has a cutting edge;

[0003] The Chinese patent (CN202320423682.1) discloses a bending mold that prevents sticking and disengagement. The external power supply of the driving motor is connected through the cooperation between the driving motor, the double-headed threaded rod, the nut, the inclined plate and the U-shaped push plate, so that the output end of the driving motor drives the double-headed threaded rod to rotate, and the double-headed threaded rod causes the two nuts to move toward the middle at the same time, and the nut drives the inclined plate to move. The inclined plate moves the U-shaped push plate upward through the inclined slide groove, and the U-shaped push plate pushes the bent sheet out of the support plate, so as to facilitate the disengagement of the sheet and prevent the sheet from being stuck below. However, when using this bending mold, additional power equipment is required to realize the ejection of the product, and the maintenance cost is high. It is not convenient to replace the bending molds of different angles according to the processing requirements of the product. The contact surface between the product and the mold is prone to scratches due to wear, which affects the product quality.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0025] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a steel bending die that prevents sticking and detachment, which is composed of a main body mechanism 10 and an ejection mechanism 20.

One side of the lower mold 11 is equidistantly provided with oil injection holes 31. Lubricating oil is injected into the ejection column 22 through the oil injection holes 31 to reduce the friction between the contact surface of the ejection column 22 and the lower mold 11 and improve the ejection efficiency. In order to prevent the lubricating oil from overflowing, a rubber disc 29 is sleeved on one side of the ejection column 22, and one side of the rubber disc 29 is fixedly connected to the connecting plate 28.

[0031] In one embodiment, in order to enhance the stability of the connecting plate 28 during movement, the lower mold 11 is symmetrically fixedly connected to the two sides of the interior with slide rails 16, the interior of the slide rails 16 is slidably connected with a slider 17, one side of the slider 17 is fixedly connected to the connecting plate 28, and the slider 17 cooperates with the slide rails 16 to enhance the movement stability of the connecting plate 28 while limiting the movable range and movement trajectory of the connecting plate 28.

[0032] When the utility model is working, the lower mold 11 is placed on the bending machine, the lower mold 11 is aligned with the upper mold, the lower mold 11 is fixed to the bending machine by the first bolt 14, the lubricating oil is injected into the contact surface between the ejector column 22 and the lower mold 11 through the oil injection hole 31, the corresponding plug plate 23 is selected according to the bending requirements of the product, the plug plate 23 is placed in the cavity 12, the plug plate 23 is fitted with the lower mold 11, the plug plate 23 is fixed by the second bolt 24, the product to be processed is placed on the lower mold 11, and the upper mold is used to extrude the product. The product is bent, and the product contacts the plug plate 23 during bending. After bending, remove the second bolt 24, connect the limit plate 25 to the lower mold 11 through the clamping block 26 and the clamping slot 27, adjust the limit height of the limit plate 25 according to the bending angle of the product and the product size, press down the seesaw 21, so that one side of the seesaw 21 pushes the connecting plate 28 to rise, and the connecting plate 28 drives the ejection column 22 to eject the plug plate 23 and the product together. After taking out the product, lightly knock on the plug plate 23 or pull the plug plate 23 to separate the plug plate 23 from the product.
