Abstract
The invention discloses a manufacturing process of a shearing rib mold, which is characterized by comprising the following steps: (1) splicing plates, and lofting; (2) folding a metal edge: folding a steel plate into a right angle at the edge of the steel plate to manufacture the edge of a shearing rib, and ensuring the angle; (3) welding a flat plate; (4) maintaining pressure of welded seams; (5) manufacturing an inner cavity of the mold; (6) laying heating strips; (7) laying heat-insulating cotton; and (8) adjusting the level of the mold. In the invention, the problems that in the prior art, the shearing rib mold is manufactured by adopting glass fiber reinforced plastics, the cost is high, and the shrinkage rate and the deformation rate of the finished mold are higher are solved. The invention provides the manufacturing process for manufacturing the shearing rib mold by using the steel plate as a raw material.
Description
Technical field
The present invention relates to a kind of mold production process, particularly relate to a kind of shearing ribs mold production process.
Background technology
The mould that is used for doing fiberglass at present has a variety of, as: wooden model, silica gel mould, plaster mold, glass punching block, punching block etc.The preparation method of fiber reinforced plastic mold: shop fiberglass cloth, re-lay copper pipe, be used for heating, resin and aluminium powder are stirred, above being layered on, repave one deck fiberglass cloth.The glass punching block has former, and formpiston to matched moulds etc., specifically selects for use type in which kind of will see the structure of product, technology, quality requirement etc.At first be that original shape spare one is exactly a formpiston, made of wooden mostly before domestic, but so long that external majority employing pasty state is constructed for wood and one will be operated with machine for fan blade.On this formpiston, turn over cavity block then, do well die joint after, can hand stick with paste or vacuum imports.
The problem that fiber reinforced plastic mold often runs in manufacturing process comprises: the steelframe die surface for wood layer cracking, yoke die surface for wood layer cracking, that the male mold surfaces light is handled is unnecessary, there is bubble at the former turning, the female mold surfaces frp layer is thicker, former fiberglass is out of shape with the hard junction of steelframe, the former steelframe does not have the thermal expansion expansion joint (E.J.), former mozzle joint is too much etc.
The shearing ribs mold production process of prior art adopts fiberglass simultaneously, and adopt glass-reinforced plastic material to make the shearing ribs mould and have following shortcoming: 1, cost of manufacture is higher.2, inefficiency, the secondary mould time of making is longer.3, die width can not be regulated as required.4, the shearing ribs mould adopts glass-reinforced plastic material, and mold shrinkage and deformation rate are higher, and be fragile, causes and can not continue to use.5, the heating system of mould is difficult to safeguard and keep in repair.
Summary of the invention
Adopt the fiberglass manufacturing in order to solve in the prior art manufacturing of shearing ribs mould, the cost height, its shrinkage factor and deformation rate problem of higher mould is finished after the invention provides a kind of manufacturing process of utilizing steel plate as raw material manufacturing shearing ribs mould.
In order to achieve the above object, the technical solution adopted in the present invention is:
1, a kind of shearing ribs mold production process is characterized in that: may further comprise the steps:
(1), jigsaw, setting-out
After 1.5 meters X2.5 rice cold rolled plates are combined into a plane, the shearing ribs finished product is positioned on the plane;
(2), metal flanging
The cold rolled plate of putting well is converted into the flange that shearing ribs is made at the right angle, leans against on the shearing ribs finished product with newly-increased L shaped plate, 1 meter one section, determine the flange size according to the shearing ribs finished size, the width of flange is 20 centimeters, highly is 9 centimeters;
(3), welding plate
The slit that to roll between the cold rolled plate behind the limit by electric welding machine welds;
(4), weld seam pressurize
Every weld seam to flat board carries out pressurize, pastes the sealing doctrine earlier at position while welding, lays water conservancy diversion net and vacuum bag film then, with vavuum pump pressure is evacuated to below the 10mbar at last;
(5), do dies cavity
The mould that has welded is stood up, shearing ribs finished product conformal is put into inner chamber, cutting width is 8.5 centimeters, thickness is that the cold rolled plate of 3mm leans against on the shearing ribs finished product limit, use electric welding machine spot welding, tamp with polyurethane foam for the hollow area beyond the shearing ribs finished product, be enclosed in above the shearing ribs finished product with the thick cold rolled plate of 3mm again;
(6), lay fire-bar
After finishing dies cavity, mould is stood up, below by the fixing fire-bar of laying of aluminum foil and adhesive tape, fire-bar is taped against small end from the big end of shearing ribs, begins to spread one every 9 centimeters from flange at mould;
(7), lay heat-preservation cotton
Heat-preservation cotton is covered the bottom of entire die, be fixed with wire netting;
(8), adjust die horizontal
Adjust die horizontal with laser leveler.
Aforesaid a kind of shearing ribs mold production process is characterized in that: heated by resistance wire at fire-bar described in the step (6), the heating-up temperature of fire-bar is 130 °.
The invention has the beneficial effects as follows: shearing ribs mold production process of the present invention utilizes steel plate materials to replace glass-reinforced plastic material, saves cost, has improved efficiency, and mold shrinkage and deformation rate will be lower than fiber reinforced plastic mold.Guarantee that by accurate manufacturing formpiston and employing segmented metal flanging the angle of dies cavity is to meet the requirements.The mould air-tightness is to guarantee mould metal seam seal by positive and negative no seam welding.The mould removable section passes through, and locating slot and locking device are fixed, and fixing back is carried out once more fixing to mould by shrouding, guarantees that the mould removable section does not occur loosening and moves phenomenon such as position.
