Background technique
The door frame channel-section steel that present stage is used for 10～12t large-tonnage fork truck tackling system is welded after mainly being to use the sheet material cutting.This welding channel-section steel is welded by wing plate and web.Large-tonnage fork truck tackling system in use need be born big and cyclic load, requires very high to aspects such as the intensity of channel-section steel, sectional dimension, profile straightness accuracy, planenesses.The welding channel-section steel need use complex apparatus, carries out loaded down with trivial details operation and could make completion, causes formation efficiency low; In cutting and welding process, metal consumption is more, causes the metal utilization rate low; The welding groove steel make the cycle long, cost is high, and the welding zone performance is also very unstable.
The model utility content
To existing 10～12t large-tonnage forklift door frame is low with complex manufacturing, the using rate of metal that the welding channel-section steel exists, the manufacturing cycle is long, the problem of welding zone unstable properties, the utility model provides a kind of channel-section steel that is used for forklift door frame.
According to the one side of the utility model, a kind of channel-section steel that is used for forklift door frame comprises wing plates on two sides and middle pectoral plate, and said channel-section steel is an overall thermal rolled piece, and the cross section groove width h1 of said channel-section steel is 184 ± 0.75mm, and the outside width h2 of cross section is 250mm; The length b of wing plate is 70 ± 1.0mm, and the thickness C of wing plate is 33 ± 1.0mm; The thickness d of web is 20 ± 0.8mm.
According to the utility model on the other hand, the end of said wing plate can have knuckle, and wherein, said knuckle Rc can be 3mm.
According to the utility model on the other hand, can be the circular arc that skew lines adds smooth transition between web and the wing plates on two sides, the distance away from the first end distance web of web of skew lines is 5mm, and the distance away from the second end distance wing plate of wing plate of skew lines is 20mm; The circular arc of smooth transition can be the circular arc of Ra by radius and circular arc that radius is Rb constitutes, and radius of arc Ra can be 50mm, and radius of arc Rb can be 8mm.
The channel-section steel that is used for forklift door frame according to the utility model has the following advantages: this hot-rolled steel channel each item dimensional parameters is extremely stable, can be used for 10～12t forklift door frame and makes; Forklift door frame manufacturing efficiency and using rate of metal obviously improve; Simplify production technology, reduce production costs; Improve the whole usability of product.
Description of drawings
Through the description of carrying out below in conjunction with accompanying drawing to embodiment, above-mentioned and/or other purposes and the advantage of the utility model will become apparent, wherein:
Fig. 1 is the schematic cross sectional views according to the structure of the channel-section steel that is used for forklift door frame of the utility model exemplary embodiment.
Embodiment
To combine accompanying drawing to describe the channel-section steel that is used for forklift door frame in detail below according to the utility model.
Fig. 1 shows the schematic cross sectional views according to the structure of the channel-section steel that is used for forklift door frame of the utility model exemplary embodiment.Referring to Fig. 1, have web and the wing plate that is positioned at the web both sides according to the channel-section steel that is used for forklift door frame of the exemplary embodiment of the utility model, wherein, said channel-section steel is the overall thermal rolled piece.As shown in Figure 1, the cross section groove width h1 of said channel-section steel is 184 ± 0.75mm, and the outside width h2 of cross section is 250mm; The length b of wing plate is 70 ± 1.0mm, and the wing plate thickness C is 33 ± 1.0mm; The thickness d of web is 20 ± 0.8mm.According to the embodiment of the utility model, each item dimensional parameters of this channel-section steel is extremely stable, and bearing power is stronger, can be used for making 10～12t large-tonnage forklift door frame.In addition, because this channel-section steel through the hot rolling once-through, therefore can be realized producing in batches and the supply of material; Manufacturing efficiency and using rate of metal obviously improve; And can reduce sheet material cutting waste product, avoid defectives such as the back pore that occurs of sheet material welding, trachoma, distortion simultaneously, improve the product overall security.
According to another embodiment of the utility model, the end of wing plate can have knuckle, thereby can reduce the wearing and tearing of the forklift door frame that utilizes this channel-section steel manufacturing.According to another embodiment of the utility model, knuckle Rc can be 3mm.
Another embodiment according to the utility model; Can be the circular arc that skew lines adds smooth transition between web and the wing plates on two sides; The size e of skew lines and size f are respectively 5mm and 20mm (specifically; The distance away from the first end distance web of web of skew lines is 5mm, and the distance away from the second end distance wing plate of wing plate of skew lines is 20mm); The circular arc of smooth transition is that the circular arc of Ra and circular arc that radius is Rb constitute by radius, and radius of arc Ra is 50mm, and radius of arc Rb is 8mm.Specifically, transit to wing plate via circular arc R a, skew lines and circular arc R b respectively from web, thereby can improve the intensity of channel-section steel.
The utility model is compared the advantage with following aspect with prior art products:
(1) the utility model each item dimensional parameters is extremely stable, and bearing power is stronger, can be used for making 10～12t large-tonnage forklift door frame.
