Embodiment
For making object of the present invention, technological scheme and advantage clearer, clear and definite, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.
As Figure 1-4, this pressure-sizing formula brake shoe iron comprises gusset 100 and panel 200, and described gusset 100 is curved, and panel 200 attachment faces match with the shape of gusset 100 attachment faces; On the attachment face of described gusset 100, be provided with protruding positioning block 110, be provided with the positioning hole 210 that runs through panel 200 on panel 200, described positioning block 110 is through positioning hole 210, and gusset 100 is fixedly connected with by pressure-sizing crimping with panel 200.
For the soundness that guarantees to install, described positioning block 110 arranges a plurality of, and positioning hole 210 arranges a plurality of, and positioning block 110 is consistent with the quantity that positioning hole 210 arranges.
The two ends of described gusset 100 are respectively arranged with arc groove 120.
As shown in Figure 5, a kind of preparation method of pressure-sizing formula brake shoe iron as described above, specifically comprises the following steps:
Steps A 00: make gusset 100 by stamping process;
Step B00: make panel 200 by stamping process;
Step C00: the positioning block on gusset 100 110, through the positioning hole 210 on panel 200, is fixedly connected with panel 200 gusset 100 by pressure-sizing, obtains brake shoe semi-finished product;
Step D00: brake shoe semi-finished product are heat-treated and surface treatment;
Step e 00: be up to the standards, obtain pressure-sizing formula brake shoe iron.
In described steps A 00, specifically comprise the following steps:
Steps A 10: check board quality, obtains qualified gusset sheet material;
Steps A 20: by gusset sheet material shear itemize;
Steps A 30: by sheet material blanking and punching;
Steps A 40: sheet material is carried out to essence punching, obtain finished product gusset 100.
In described step B00, specifically comprise the following steps:
Step B10: check board quality, obtains qualified face plate;
Step B20: by face plate shear itemize;
Step B30: by sheet material shear blanking;
Step B40: sheet material is carried out to punching;
Step B50: be up to the standards, obtain finished product panel 200.
This pressure-sizing formula brake shoe iron is offered positioning hole on panel, and protruding positioning block is set on gusset, by positioning block, coordinates pressure-sizing to fix with positioning hole, has replaced the technology mode being welded and fixed; The brake shoe iron making by the present invention has many merits: 1. lightweight: owing to adopting steel plate stamping to connect, alleviated the weight of break, the brake shoe weight ratio casting hoof of same specification fall heavy 20-30%(because of specification different different); Such as, casting hoof weight 9.6 kg of steyr bridge, pressure-sizing hoof weighs 7.1, single weight saving 2.5kg, the light 10kg of every bridge, loss of weight 26%, the light-weighted development trend of responsive motor; 2. cost is low: because pressure-sizing brake shoe is lightweight, process for machining and manufacturing is simple, and cost can reduce approximately 10%; 3. performance is good: because the material steel of making of pressure-sizing brake shoe has larger elasticity, make brake lining and the brake drum tight area of contact of fitting increase during braking, simultaneously because the quality of pressure-sizing brake shoe is light, shortened reaction time; 4. can realize the not uniform thickness design of friction plate: because the brake shoe of cam drum type brake rotates around fixed pin shaft, therefore the wearing and tearing of friction plate are not even, for casting brake shoe, owing to need to processing with friction plate faying surface, cannot make irregularly shaped, so existing casting shoe friction plate is all uniform thickness design, because pressure-sizing hoof is that punching press makes, without faying surface is processed, can realize the not uniform thickness design of friction plate; The design of uniform thickness friction plate can not make the friction plate utilization of same weight more abundant, improves 20% working life, and cost of material also can reduce simultaneously; 5. convenient disassembly: this brake shoe is lightweight with respect to casting hoof, convenient disassembly, is easy to after-sales service maintenance; 6. processing technology is simple, and manufacturing efficiency is high: utilize punching press pressure-sizing technology generations for welding procedure, improved widely manufacturing efficiency, shortened the process-cycle, avoided producing the pressure of cast blank demand in enormous quantities, the up-to-standard rate of product is improved; 7. avoided because of casting and welded the environmental pollution bringing; 8. quality control requirement is strict: the conformity of course of working is controlled simpler, and punching press, compression joint technique are had relatively high expectations, the problem of having avoided welding to bring.
This pressure-sizing formula brake shoe iron manufacturing process is few, technique is simple, with short production cycle, time saving and energy saving, manufacturing mechanism configuration requirement is few, does not have the operation of the consumption equipment consuming time such as welding, bore hole, utilizes the connection of pressure-sizing fixed panel and gusset, not only guaranteed precision, the intensity of whole brake shoe iron, and the appearance quality of whole brake shoe iron also increases greatly.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
