Description

Wearing proof roller inlaid with alloyed block

The utility model relates to a kind of surface strengthening technology that is subjected to grinding machine spare, and the wear-resisting roller of alloy block is inlayed on particularly a kind of surface.

In order to reduce the loss that mechanical spare part causes because of wearing and tearing, people have adopted the technological measure of multiple reinforcement surface of the work, as heat treatment, built-up welding, spraying, surfacing, plating, brush plating, and ball blast, multicomponent thermochemical treatment or the like, these processes, characteristics are respectively arranged,, all obtained good effect under certain condition, but also weakness has been arranged respectively, limit by some factor, can't bring into play its effect.As technologies such as built-up welding, surfacing, heat treatments, very easily cause distortion, or change original some characteristic of material, and electroplate, technology such as brush plating, then dislike strengthening effect relatively poor, particularly strengthening layer is too thin, some harsh working condition requirement of incompatibility.Co-permeation method or other heat treating process then except the problems referred to above are arranged, are subjected to effects limit such as capacity of equipment, process conditions toward contact, in production practices, particularly are difficult to adopt in the spare part repair process.

The purpose of this utility model is: provide a kind of and arrange in order and inlay the wear-resisting alloy block of some and size being ground part surface, improve parts service life thereby reach, can not destroy the surface peening purpose of primary characteristic and precision again.

The purpose of this utility model realizes by following measure:

On the surface of roller, arrange in order and be inlaid with alloy block.Alloy block is to inlay to join to be cemented in the prefabricated eyelet of roller surface.Described alloy block is columniform.Being ground on the surface of parts, disperse the inlaying abrasion-resistant alloy piece, support foreign object with these wear-resisting alloy blocks, protect mechanical spare part surface not to be subjected to the wearing and tearing of these foreign objects.Because the wear-resisting alloy block inlayed distributes rationally, the performance that superb hardness is more arranged and resist abrasive wear, thereby service life of prolonged mechanical spare part greatly.In order to improve the intensity of inlaying of alloy block, on the suitable position of wear surface, mill out the eyelet that dimensional accuracy is suitable for inlaying alloy block.Alloy block is bumped in the eyelet, and cements with binding agent.The working condition requirement of parts is depended in the selection of alloy block composition, performance, as, running at high temperature, can adopt YG class alloy, under the rapid heat cycle condition, work, can adopt the steel-bonded carbide of the different trades mark, or other high temperature wear resistant alloy.Selection of binder also is that the concrete working condition such as environment temperature, medium, part throttle characteristics according to parts work is determined.Bonding operation comprises that the preparation of medicament, surface of the work clean, the baking after the bonding, residue treatment, processing or the like, all by the special provision processing of binding agent.For simplify technology, alloy block is columniform, the fit clearance of it and eyelet is as the criterion with the specific requirement that is fit to binding agent, selects between 0.1 to 0.5 millimeter usually.The size of alloy block, is determined according to the power of parts actual load spacing.Should carry out necessary figuring of surface, processing after the bonding.

Advantage of the present utility model and effect are:

1, bonding process can not influence the original physical and mechanical properties of parts body and alloy block, accepts for the user easily.

2, can select the trade mark of alloy block arbitrarily, obtain desirable anti-wear performance, thereby can significantly improve the service life of parts.

3, the utility model adopts deep hole bonding, and steady quality operate simple and easyly, and can obtain the highest adhesion strength, so stable and reliable for performance.

4, to equipment do not have specific (special) requirements, material aboundresources, the strengthening layer controllable parameter is many in addition, adaptability is strong, thereby can extensively promote the use of.

Below in conjunction with accompanying drawing, be example with the fanning strip that is applied to steel rolling mill's tandem rolling roll bending arbor, the utility model is further described.

Fig. 1, this is fanning strip sketch (being Japanese import parts) the about 600kg of substance of tandem rolling roll bending arbor, and material is 35CrMo, and the normalizing attitude is used, hardness HB200-250, during work, the external cylindrical surface steel plate strong wear of being heated.

Fig. 2, this is the part sectioned view of above-mentioned fanning strip.In above two figure, the 1st, the fanning strip body, the 2nd, the alloy block that adopts the utility model technology to be inlayed, material is a DT shaped steel joining gold, specification φ 14 * 14, the 3rd, the high temperature modification inorganic binder, it has good water-fast, oil resistant erosion performance, model as: 208.

Surplus this fanning strip, every cover unit price 20 ten thousand yuan.Be subjected to hot rolled plate (650 ℃) wearing and tearing during work, loss is very big: wear away 5 millimeters need every half a year and once repair, 100,000 yuan of each prices for repairing are scrapped (having worn and torn 15 millimeters) after the reconditioning 3 times because of reaching the minimum limit of size.

After adopting the utility model, the life-span can be brought up to more than 6 years, was 3-5 times of former life-span.

Claims (3)

1, a kind of wear-resisting roller of inlaying alloy block is characterized in that on the surface of roller 1, arranges in order and is inlaid with alloy block 2.

2, wear-resisting roller as claimed in claim 1 is characterized in that alloy block 2 is that edge is joined and is cemented in the prefabricated eyelet of roller surface 1.

3, wear-resisting roller as claimed in claim 1 is characterized in that described alloy block 2 is columniform.
