Abstract
The invention discloses a regenerative repair method for a template of a die-casting machine. The method comprises the following steps: surfacing a new material on the template of the die-casting machine by adopting a welding technique and welding equipment; adding a new rustproof material on a concave-convex template without dismounting the die-casting template, subsequently performing finish machining, and directly performing machining and cutting operation on the body of the die-casting machine to maintain the original size of the template of the die-casting machine; after sweeping the surface of the template, measuring the wear condition of the surface of the template by using a special measuring instrument; sequentially performing welding, machining and surface measurement steps and finally performing site confirmation. According to the method disclosed by the invention, repair can be realized without detaching the machine, a special machining machine is used for performing plane machining, and machines different in size can be repaired. Recesses of the template are repaired by using a special corrosion-resistant and wear-resistant welding material, and the surface is milled on site by using a special machining machine, so the template of the die-casting machine reaches the precision of a new machine leaving the factory and is also higher in corrosion resistance and longer in service life than a new machine.
Description
Technical field
The invention belongs to die casting machine accessory recovery technique field, the regeneration particularly relating to a kind of die-casting machine is repaiied
Compound recipe method.
Background technology
Die casting machine is under pressure cooling down molding in molten metal bath injection to mould, obtains solid gold after die sinking
Belong to a series of industry foundry machinery of foundry goods, be used primarily for die casting font.Along with scientific and technical and industrial progress, especially
Being as the industrial expansions such as automobile, motorcycle and household electrical appliance, set out from many aspects, die-casting technique has obtained the rapidest
Development.Die casting machine is because the corrosion of matched moulds and mould release repeatedly makes the template face of fixing mould occur in that abrasion, and constantly
Deteriorate.The generation of die plate, is also the main cause causing the bad phenomenon such as overlap and burr.The biography of die-casting machine maintenance
System method is directly to ream, material or original, still can cave in, and renovation technique traditional in prior art needs to take machine apart
Device, puts down template milling, and repair process is extremely complex loaded down with trivial details, and cannot recover size of dispatching from the factory.
Summary of the invention
The deficiency that the present invention exists to overcome prior art, it is provided that a kind of need not to take apart what machine can carry out repairing
The Regeneration and Repair method of die-casting machine.
The present invention is achieved by the following technical solutions: a kind of Regeneration and Repair method of die-casting machine, uses welding
Technology, the material using welding equipment built-up welding new on die-casting machine gets on, and does not tear machine open, and die casting template is not pulled down, concavo-convex
Plus new rush-resisting material in template, then carry out polish, be directly processed on the machine of die casting machine and cutting operation, add
Work precision can reach below 0.1mm, higher than dispatching from the factory precision, and technology is novel, makes the size that die-casting machine holding is original；First
First after the cleaning completing template face, use special mensuration equipment to measure the abrasion condition in template face；Then in turn through
Welding step, mechanical processing steps and finished surface determination step, finally carry out checking and on-the-spot confirm that step can complete to repair.
Mechanical processing steps particularly as follows: first with nickeliferous more than 95% welding rod soldering recess；Then process with facade
Machining solder side, makes the reparation of die-casting machine reach the precision needed, and facade processing machine is fixed on the big bar of die casting machine,
And the machining accuracy of machine is adjusted by amesdial.
Finished surface determination step particularly as follows: on the basis of the part not having contacting dies point, with leveling ruler detection die casting machine its
Its position and the difference of height of datum mark.The welding equipment used in welding step is general A.C. welder, guide pillar screw socket seat surface
Built-up welding processing, the adjustment of big bar also can carry out.
The invention has the beneficial effects as follows: method traditional in prior art is to tear machine maintenance open, and the feature of present invention maximum is
Need not take machine apart can repair, and utilize special processing machine to carry out plane machining, the present invention can be for 125 tons
Keep in repair to 4000 tons of different size of machines.The invention belongs to the abrasion unscheduled maintenance fortification at scene, the present invention uses spy
Have has the outstanding corrosion-resistant and special welding material of wearability, and the performance of template can be made to be greatly improved.The present invention
Using solder technology, weld new material up, need not tear machine open on die-casting machine, die casting template is pulled down without template, recessed
Convex template is plus new rush-resisting material, then carries out polish, on direct machine, keeps original size, will not regenerate rust deformation.This
Invent and repair template depression by special anticorrosive wear-resistant welding material, and by the flat surface of special processing machine milling at the scene,
The template making die casting machine reaches new machine precision of dispatching from the factory, simultaneously can also ratio new engine more corrosion resistance, there is the longer life-span.
As in figure 2 it is shown, the present invention uses the actual measurement data of uniform machinery to compare to carry out abrasion performance, comparative result
As shown in table one and table two:
Table one: the abrasion loss after newly machine uses 4 years:
| Unit (mm) | A | B | C | D | E |
| 1 | -0.40 | -0.40 | -0.50 | -0.40 | -0.40 |
| 2 | -0.70 | -0.70 | -0.80 | -0.70 | -0.70 |
| 3 | -0.70 | -0.80 | -0.80 | -0.80 | -0.70 |
| 4 | -0.70 | -0.70 | Lining | -0.60 | -0.60 |
| 5 | -0.50 | -0.50 | -0.50 | -0.50 | -0.50 |
Table two: use the abrasion loss after Regeneration and Repair method built-up welding of the present invention 4 years:
| Unit (mm) | A | B | C | D | E |
| 1 | 0.00 | -0.02 | -0.03 | -0.02 | 0.00 |
