Abstract

The invention discloses a processing technique for pressing a roller bracket. The processing technique for pressing the roller bracket is that a rubber fitting is prepared through rubber material for a fixing bracket to be poured, and the rubber fitting wraps the fixing bracket after being cooled so as to protect the fixing bracket and facilitate the transportation; a pressing roller to be equipped with the bracket is compressed on the fixing bracket to be poured through a U-shaped locating sheet and a compressing block; the pressing roller and the fixing bracket are respectively connected to two ends of the U-shaped locating sheet and the compressing block, wherein the compressing block is a metal pressing block which is in magnetic combining with the U-shaped locating sheet; the pressing roller, the U-shaped locating sheet, the compressing block and the fixing bracket are integrally fed into a preset die, and the prepared hot metal is poured into the preset die to pour together through a pouring machine by the die pouring method. The processing technique for the pressing roller bracket has the advantages of being high in production efficiency, high in product quality and low in processing cost.

Description

A kind of processing technology of pressing roller holder

Technical field

The present invention relates to field of mechanical technique, particularly, relate to a kind of processing technology of pressing roller holder.

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 and compact heap by riveted joint and compress.The connection procedure of riveted joint has very high tolerance.Therefore, be necessary that U-shaped spacer and compact heap are compressed the fixed mount utilizing 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 a kind of processing technology of pressing roller holder, 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: a kind of processing technology of pressing roller holder, comprising: adopt elastomeric material, for fixed support to be cast is equipped with fixed support rubber accessory; This fixed support rubber accessory is used for the support that is coated and fixed after the cooling period, to protect fixed support and to be convenient to transport;

By needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer and compact heap; Pressure roller and fixed support are connected to the two ends that U-shaped spacer and compact heap compress; Compact heap is the metallic briquette arranged by magnetic attraction type with U-shaped spacer;

By pressure roller, U-shaped spacer, compact heap compresses and fixed support puts 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 that U-shaped spacer and compact heap compress 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.

Further, described U-shaped spacer and compact heap compress horizontally set.

The processing technology of a kind of pressing roller holder of various embodiments of the present invention, owing to comprising: adopt elastomeric material, for fixed support to be cast is equipped with fixed support rubber accessory; This fixed support rubber accessory is used for the support that is coated and fixed after the cooling period, to protect fixed support and to be convenient to transport; By needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer and compact heap; Pressure roller and fixed support are connected to the two ends that U-shaped spacer and compact heap compress; Compact heap is the metallic briquette arranged by magnetic attraction type with U-shaped spacer; By pressure roller, U-shaped spacer, compact heap compresses and fixed support puts 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 that U-shaped spacer and compact heap compress 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; 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 a kind of processing technology of pressing roller holder, comprising: adopt elastomeric material, for fixed support to be cast is equipped with fixed support rubber accessory; This fixed support rubber accessory is used for the support that is coated and fixed after the cooling period, to protect fixed support and to be convenient to transport;

Step 1: by needing the pressure roller being equipped with support, be pressed on fixed support to be cast by U-shaped spacer and compact heap; Pressure roller and fixed support are connected to the two ends that U-shaped spacer and compact heap compress; Compact heap is the metallic briquette arranged by magnetic attraction type with U-shaped spacer; Here, U-shaped spacer compresses with compact heap and can play the effect being connected and locating;

In step 1, U-shaped spacer and compact heap compress horizontally set;
