Abstract
The invention discloses a manufacturing method for a press roller support. The manufacturing method includes the steps that a pouring die is arranged on the basis of a fixed support to be poured, and the needed fixed support is obtained through pouring of the pouring die; the fixed support obtained through pouring is calcined, cooled with water, grinded and polished, and grinding dust on the surface of the fixed support is blown away through a blower; a press roller needing to be provided with the support is pressed on the fixed support to be poured through a U-shaped positioning piece; the press roller and the fixed support are connected to the two ends of the U-shaped positioning piece respectively; the press roller, the U-shaped positioning piece and the fixed support are put into the preset die together as a whole, and molten metal liquid prepared in advance is poured into the preset die to be poured together through a pouring machine by adopting a die pouring method. The manufacturing method for the press roller support can overcome the defects of being low in production efficiency, poor in product quality and high in machining cost in the prior art and has the advantages of being high in production efficiency, good in product quality and low in machining cost.
Description
Technical field
The present invention relates to field of mechanical technique, particularly, relate to pressing roller holder manufacture method.
Background technology
Pressure roller is in extrusion molding coating and calendering coating, the rubber rollers combinationally used with chill roll, stack respectively.
The effect of pressure roller be the film of extrusion molding or calendering is overlayed with base material equably together with.Also together with the base material scribbling sizing material can being overlayed with adhesive in sticking tape manufacture process.Sometimes also refer to the rubber rollers on embossing machine, it can coordinate with engraved roll, and tablet carries out even embossing.
With pressure roller with the use of pressing roller holder, fixed mount can be manufactured with aluminium diecasting, and be fixed on U-shaped spacer by riveted joint.The connection procedure of riveted joint has very high tolerance.Therefore, be necessary U-shaped spacer to be utilized the fixed mount of riveted joint fixing in one apparatus, and chip processing is carried out to fixed mount in the region fixing the roll shaft of twin pressure roller afterwards.Ensure that twin pressure roller is accurately parallel to affiliated drafter lower roll later and positions by carrying out chip processing to fixed mount.At this, the shortcoming of this pressing roller holder is, its manufacture process is very bothersome and comprise much different operations.
Realizing in process of the present invention, inventor finding at least to exist in prior art that production efficiency is low, poor product quality and the defect such as processing cost is high.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose pressing roller holder manufacture method, to realize that production efficiency is high, good product quality and the low advantage of processing cost.
For achieving the above object, the technical solution used in the present invention is: pressing roller holder manufacture method, comprising:
Based on fixed support to be cast, casting mold is set, obtains required fixed support by the cast of this casting mold; To calcine and after water cooling process, sanding and polishing, then blows away the polishing dust on fixed support surface with hair-dryer pouring into a mould the fixed support that obtains;
By needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer; Pressure roller and fixed support are connected to the two ends of U-shaped spacer;
Pressure roller, U-shaped spacer and fixed support are put into preset die as a whole, by casting machine, adopts mould note method, pre-prepd molten metal bath is poured in preset die and pours into a mould together; The fusion point of U-shaped spacer is higher than the fusion point of pre-prepd molten metal bath;
Be poured, when bubble-free is emerged in the steel cylinder of pre-prepd molten metal bath to be contained, carry out machinery and play steel, then by the Slag recovering in steel cylinder and class wrapping, and be transported to recycle bin.
Further, described U-shaped spacer horizontally set.
The pressing roller holder manufacture method of various embodiments of the present invention, owing to comprising: based on fixed support to be cast, arrange casting mold, obtains required fixed support by the cast of this casting mold; To calcine and after water cooling process, sanding and polishing, then blows away the polishing dust on fixed support surface with hair-dryer pouring into a mould the fixed support that obtains; By needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer; Pressure roller and fixed support are connected to the two ends of U-shaped spacer; Pressure roller, U-shaped spacer and fixed support are put into preset die as a whole, by casting machine, adopts mould note method, pre-prepd molten metal bath is poured in preset die and pours into a mould together; The fusion point of U-shaped spacer is higher than the fusion point of pre-prepd molten metal bath; Be poured, when bubble-free is emerged in the steel cylinder of pre-prepd molten metal bath to be contained, carry out machinery and play steel, then by the Slag recovering in steel cylinder and class wrapping, and be transported to recycle bin; Thus can overcome that production efficiency in prior art is low, poor product quality and the high defect of processing cost, to realize that production efficiency is high, good product quality and the low advantage of processing cost.
Other features and advantages of the present invention will be set forth in the following description, and, partly become apparent from description, or understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
According to the embodiment of the present invention, provide pressing roller holder manufacture method, comprising:
Preliminary step: based on fixed support to be cast, arrange casting mold, obtains required fixed support by the cast of this casting mold; To calcine and after water cooling process, sanding and polishing, then blows away the polishing dust on fixed support surface with hair-dryer pouring into a mould the fixed support that obtains;
Step 1: by needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer; Pressure roller and fixed support are connected to the two ends of U-shaped spacer; Here, U-shaped spacer can play the effect connecting and locate;
In step 1, U-shaped spacer horizontally set;
Step 2: pressure roller, U-shaped spacer and fixed support are put into preset die as a whole, by casting machine, adopts mould note method, is poured in preset die by pre-prepd molten metal bath and pour into a mould together; The fusion point of U-shaped spacer is higher than the fusion point of pre-prepd molten metal bath;
Step 3: be poured, for safety, when bubble-free is emerged in the steel cylinder of need pre-prepd molten metal bath to be contained, then carries out a machinery steel, then by the Slag recovering in steel cylinder and class wrapping, and is transported to recycle bin; By the recycling to residue, processing cost can be saved.
In sum, pressing roller holder manufacture method of the present invention, the material that can gain in strength to a great extent plastics fusion, such as glass fibre; Do not affect the machinability of product in injection moulding process, but extremely effectively prevent " creep " of plastics; And processing cost is low.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
