Description
Technical field
The utility model relates to shaped steel technical field, particularly a kind of forklift door frame hot rolling small dimension channel-section steel for little tonnage electri forklift tackling system.
Background technique
At present, be welded after mainly using plate cutting for the gantry channel-steel of little tonnage electri forklift tackling system.This welding channel-section steel is welded by wing plate and web.Little tonnage fork car tackling system in use needs to bear cyclic load, requires very high to the aspect such as intensity, sectional dimension, profile straightness accuracy, planeness of channel-section steel.Welding channel-section steel needs to use complicated equipment, and carrying out loaded down with trivial details operation could manufacture, and causes formation efficiency low; In cutting and welding process, metal consumption is more, causes metal utilization rate low; The welding groove steel making cycle is long, cost is high, and welding zone performance is also very unstable.
Summary of the invention
The purpose of this utility model is to provide a kind of forklift door frame hot rolling small dimension channel-section steel, the problems such as complex manufacturing, using rate of metal that prior art exists are low to solve, welding zone unstable properties.
In order to solve the problem, the utility model provides following technological scheme:
A kind of forklift door frame hot rolling small dimension channel-section steel, wherein, this hot rolling small dimension channel-section steel is an overall thermal rolled piece and comprises wing plates on two sides and the middle pectoral plate between described wing plates on two sides; Cross section outside width, the groove width of this hot rolling small dimension channel-section steel are respectively 121 ~ 122mm, 77 ~ 80mm; Described wing plates on two sides thickness, length, end knuckle, exterior bottom knuckle are respectively 21 ~ 22mm, 40 ~ 42mm, 4 ~ 6mm, 4 ~ 6mm; Described web thickness is 10 ~ 11mm.
Preferably, in a mode of execution of above-mentioned forklift door frame hot rolling small dimension channel-section steel, the intermediate location between described web and wing plates on two sides is the circular arc of two sections of smooth transition and the skew lines between the circular arc of described two sections of smooth transition.
Preferably, in a mode of execution of above-mentioned forklift door frame hot rolling small dimension channel-section steel, the projection size of the intermediate location between described web and wing plates on two sides on described wing plate and web is respectively 5 ~ 6mm, 14 ~ 15mm.
Preferably, in a mode of execution of above-mentioned forklift door frame hot rolling small dimension channel-section steel, the radius of the circular arc of the circular arc of the described smooth transition between described skew lines and web, the described smooth transition between described skew lines and wing plate is respectively 3 ~ 5mm, 5 ~ 6mm.
Analyze known, the utility model is by hot rolling once-through, and can realize batch production and the supply of material, manufacturing efficiency and using rate of metal significantly improve, and every dimensional parameters is stablized, and bearing power is stronger, can be used for manufacturing the manufacture of little tonnage electri forklift door frame.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, the utility model embodiment provides a kind of little tonnage electri forklift door frame hot-rolled steel channel, and it is an overall thermal rolled piece, and comprises wing plates on two sides and the middle pectoral plate between wing plates on two sides.Because the position of wing plate, web, structure are clear, complete, simultaneously in order to avoid the mark of the following each data parameters of index line impact of reference character, Fig. 1 does not mark wing plate, web, those skilled in the art should understand that this.
Again as shown in Figure 1, in the cross section of the present embodiment, the cross section outside width h1 of the present embodiment is 121 ~ 122mm, and cross section groove width h2 is 77 ~ 80mm.Wing plates on two sides thickness C is 21 ~ 22mm, and wing plate length b is 40 ~ 42mm, and the knuckle Rc of wing plate end is 4 ~ 6mm, and the knuckle Rd of wing plate exterior bottom is 4 ~ 6mm.Web thickness d is 10 ~ 11mm.
Preferably, the circular arc that intermediate location is skew lines and two sections of smooth transition is connected between web with wing plates on two sides, skew lines is between two sections of circular arcs, and projection size e and the size f of this intermediate location vertical projection on wing plate, web are respectively 5 ~ 6mm and 14 ~ 15mm.The radius of the circular arc of the smooth transition between this skew lines and web is Ra, and the radius of the circular arc of the smooth transition between this skew lines and wing plate is Rb, and wherein, radius of arc Ra is 3 ~ 5mm, and outer arc radius Rb is 5 ~ 6mm.
Tentative detection after trial-production the utility model shows, the utility model has the advantage of following aspect compared with prior art products:
The utility model is by hot rolling once-through, every dimensional parameters and stable, bearing power is stronger, reduce plate cutting waste product, the defect such as pore, trachoma, distortion occurred after simultaneously avoiding sheet material to weld, improve Total Product Security, can be used for manufacturing the manufacture of little tonnage electri forklift door frame.
Can realize batch production and the supply of material, manufacturing efficiency and using rate of metal significantly improve, and use this channel-section steel to manufacture little tonnage electri forklift door frame, and can shorten fork truck manufacturing enterprise in the manufacture cycle manufacturing forklift door frame, cost of production significantly reduces.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
