Abstract
The utility model discloses a regenerative end cover, belonging to the field of mechanical parts, and in particularly relating to a cover end. The regenerative end cover comprises a cover body; and the cover body is provided with a though hole. The regenerative end cover is characterized in that the through hole is internally provided with a cylinder sleeve, and the cylinder sleeve is in interference fit with the inner wall of the through hole. The inner wall of the cover body is provided with the cylinder sleeve, and the cylinder sleeve is in interference fit with the inner wall of the cover body, and therefore, not only the problem of serious abrasion in the inner wall of the wasted end cover is corrected to prolong the service life, but also the cylinder sleeve can be made from an abrasion-resistant material to lead the inner wall of the end cover to be hardly abraded and have low repairing and machining cost. The regenerative end cover can be machined by the wasted end cover which is excessively abraded, thereby not only being economic and saving, but also being good for the development of circular economy.
Description
Technical field
The utility model belongs to the component of machine field, is specifically related to a kind of end cap.
Background technique
At present the end cap that is used on the press in the industrial production mostly is single layer structure, and long working makes lid through-hole wall serious wear, and is of a specified duration with badly damaged its matching gap, finally causes scrapping.Utilize traditional heat treatment method to improve the working surface wear resistance, complex process, cost is higher, can't properly settle this difficult problem; If whole lid is adopted the high-strength abrasion-proof material, though can effectively prolong the working life of end cap, the high and processing difficulties of lid fabricating cost not only like this loses more than gain.Therefore, the end cap for the long service serious wear can only be forced to abandon at present, has caused serious waste.Design that a kind of to utilize discarded end cap machine shaping and wear-resisting, with low cost, the long-lived end cap of inwall be the task of top priority.
The model utility content
The technical problem that the utility model solved is: designed a kind of regeneration end cap, inwall is wear-resisting, has prolonged the working life of end cap.
The technological scheme that its technical problem that will solve the utility model adopts is: design a kind of regeneration end cap, comprise lid, offer through hole on the lid, it is characterized in that being provided with in the through hole cylinder sleeve, cylinder sleeve and through-hole wall interference fit.
A kind of regeneration end cap described in the utility model it is characterized in that cylinder sleeve and lid end face align, and cylinder sleeve is connected by the alloy wlding with the end face junction of lid.Cylinder sleeve adopts wear-resistant material.
The beneficial effect that the utility model had is:
1. the utility model is provided with cylinder sleeve in lid, and cylinder sleeve and lid inwall interference fit have not only been revised the serious problem of end cap inner wall abrasion of scrapping, prolonged its working life, and cylinder sleeve can adopt wear-resistant material, makes the end cap inwall be difficult for being worn, and repairs low processing cost.
2. cylinder sleeve and lid end face align, and cylinder sleeve is connected by the alloy wlding with the end face junction of lid, and it is more tight to make cylinder sleeve be connected with lid, and are difficult for producing torsional slip in the course of the work.
3. the utility model is simple in structure, and is reasonable in design, suitable penetration and promotion and industrialization volume production.
4. the utility model can utilize the end cap of scrapping of excessive wear to process, the not only economic development of saving but also helping recycling economy.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to structural representation;
Among the figure: 1. lid, 2. cylinder sleeve.
Embodiment
A kind of regeneration end cap described in the utility model, offer through hole on the lid 1, cylinder sleeve 2 is set in the through hole, cylinder sleeve 2 and through-hole wall interference fit, this structure has not only been revised the problem of scrapping end cap through-hole wall serious wear, has prolonged its working life, and cylinder sleeve 2 can adopt wear-resistant material, make that inwall is difficult for being worn, repair low processing cost.Cylinder sleeve 2 aligns with lid 1 end face, and cylinder sleeve 2 is connected by the alloy wlding with the end face junction of lid 1, and it is more tight to have made cylinder sleeve 2 be connected with lid 1 since like this, and difficult in the course of the work generation torsional slip.The utility model can utilize the end cap of scrapping of excessive wear to process, the not only economic development of saving but also helping recycling economy.Specific process is as follows:
1) wheeled litter of getting on the bus goes to scrap end cap through-hole wall (material: fray 2-20mm cast iron);
2) find cooperation, interference 0.05-0.10mm, one of the new steel bushing of car (45# steel);
3) press machine is pressed into cylinder sleeve 2 in the through hole;
4) go into baking oven, preheating when temperature arrives more than 250 ℃, is taken out;
5) with the alloy electrode welding, go into baking oven after the welding, temperature 80--250 ℃, be incubated 11-12 hour;
6) the wheeled litter downhand weld of getting on the bus;
7) going up grinding machine mill through hole to required size gets final product.
Claims (3)
1. a regeneration end cap comprises lid, offers through hole on the lid, it is characterized in that being provided with in the through hole cylinder sleeve, cylinder sleeve and through-hole wall interference fit.
2. a kind of regeneration end cap according to claim 1 it is characterized in that cylinder sleeve and lid end face align, and cylinder sleeve is connected by the alloy wlding with the end face junction of lid.
3. a kind of regeneration end cap according to claim 1 and 2 is characterized in that cylinder sleeve adopts wear-resistant material.
