Abstract
The present invention relates to a method for repairing a sugarcane pressing roller having the problem of tooth loss or local damage, which comprises the steps that two clamping sleeves in a semi-circular ring shape are arranged in the position with excision damage in a circular ring groove formed on the pressing roller; tapered blocks are embedded in the position of a bell mouth formed in the position of the interface of the two clamping sleeves and are prefastened by screw bolts. The repair method has the characteristics of simplicity, convenience, low cost and reliable use, and furthermore, the repair can be completed on site by ordinary original mechanical processing equipment.
Description
The present invention is a kind of restorative procedure of pressure roller, particularly relates to local damage or collapses the restorative procedure of the cane pressing roller of sugar of tooth.
At present, press the used cane pressing roller of sugar of sugared industry and be the cast iron materials manufacturing, and cast iron hardness is low, fragility is big, organizes more loose.The pressure roller volume is big and heavy in addition, can't heat-treat to improve performance.Therefore the normal stone that sandwiches in because of sugarcane raw material or the hard thing of ironware spare class make pressure roller be subjected to strong extruding in pressing the sugarcane process, thereby cause the press nips avalanche, severe patient even cause the avalanche of the whole circle of adjacent press nips to cause pressure roller to be scrapped, this class accident happens occasionally, and the factory that all need have a large scale computer process equipment to the reparation of the pressure roller of local damage according to a conventional method can implement, the expense that this had both increased the round transport pressure roller has importantly influenced normally carrying out of the production of pressing season.
The purpose of this invention is to provide a kind of restorative procedure that utilizes common apparatus can repair the pressure roller of local damage on the spot, this method technology is simpler, with low cost, uses reliable.
The present invention is achieved in that it is that cutting ferrule with two semi-annular shapes places the excision damaged location and the annular groove that forms on pressure roller, to up and down with bonding agent earlier, cutting ferrule is adhered in the annular groove, there are two inner small and outside big horn mouths at the interface surface place of two cutting ferrules, after treating that bonding agent solidifies, making cutting ferrule and pressure roller fixed along the inboard welding of the horn mouth of two cutting ferrule interfaces is one, the awl piece that shape and horn mouth same widths and cutting ferrule is similar embeds and is adhered in the horn mouth of cutting ferrule interface, device has its screw thread position to scribble the fixing bolt that adds of bonding agent between cutting ferrule and pressure roller and awl piece and pressure roller, makes the profile of tooth identical with press nips on the outer peripheral face of cutting ferrule and awl piece.
The angle that horn mouth became at cutting ferrule interface surface place is 50 °～75 °.
Because this method only needs the precompose cutting ferrule, the awl piece, join and do to reinforce screw etc. thereby have simple and easy to do, the advantage that the cost of repairs is low, particularly sugar refinery does not generally need pressure roller with local damage to be sent to the other places to use main equipment processing just to reprocess can to use the common apparatus reparation on the spot, thereby not only reduced freight, importantly in extraction period, won the service life that the valuable production time has prolonged pressure roller.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is for repairing the axial sectional structure schematic diagram at position.
Fig. 2 is the drawing in side sectional elevation that cutting ferrule, awl piece are installed on roll shaft.
Fig. 3 is the welding schematic diagram of upper and lower cutting ferrule and roll shaft.
Fig. 4 is the stereogram of awl piece.
By Fig. 1; Fig. 2 as can be known; this method is that to collapse the turning of tooth place on the roller be the integral multiple that the width of an annular groove 2, annular groove 2 should be press nips 5 tooth pitches with pressing; the degree of depth then should both be considered the intensity of the cover 3,7 that is installed; again greater than the limit of wear of pressure roller 1; to be coated with last layer thickness be behind 0.2～0.4 millimeter the bonding agent 4 in accordance with regulations technological requirement on the two sides of the cutting ferrule 3,7 that size is conformed to and the inner peripheral surface; pack in the annular groove 2, attention should make the thickness of bonding agent 4 keep evenly to guarantee to obtain desirable adhesion strength.Bonding agent preferably uses two component epoxy type 914 room temperature fast-curing bonding agents.Cutting ferrule 3,7 is in the annular groove 2 of packing into the time, and two interface surfaces of two cutting ferrules should keep 5～15 mm clearance of having an appointment, and form at this interface surface place one by the inboard outwards expansion to have angle be 50 °～75 ° horn mouth 9.After treating that bonding agent 4 solidifies, remove the dirt at interface surface place, upper and lower cutting ferrule 3,7 is welded on the pressure roller 1, the three is become one along the interior side clearance of interface surface horn mouth 9.Cleaning will bore piece 6 behind the weld and press technique for sticking and stipulate cleaning, coating adhesive, and will bore piece 6 and pack in cutting ferrule 3, the 7 formed horn mouths 9.After treating that bonding agent solidifies, reaching boring, tapping between awl piece 6 and the pressure roller 1 between cutting ferrule 3,7 and the pressure roller 1, can screw in to strengthen cutting ferrule 3,7 so that add fixing bolt 8, fastness between awl piece 6 and the pressure roller 1, the arrangement quantity of bolt 8 and diameter, length should be according to the pressure roller diameters, and cutting ferrule and awl piece size are determined.Before screwing in bolt 8, clean the screw and the bolt 8 that match with bolt 8, and behind coating adhesive on screw and the screw rod 8, screw rod 8 screwed in, treat adhesive cures after, be machined to required appearance and size and squeezing profile of tooth to repairing the position.
Claims (2)
1. the restorative procedure of cane pressing roller of sugar local damage, it is the cutting ferrule 3 with two semi-annular shapes, 7 place excision to collapse the tooth position and the annular groove 2 that forms on pressure roller 1, it is characterized in that: use bonding agent 4 cutting ferrule 3 up and down, 7 are adhered in the annular groove 2, two cutting ferrules 3, there are two inner small and outside big horn mouths 9 at 7 interface surface place, after treating that bonding agent 4 solidifies, horn mouth 9 inboard welding along two cutting ferrule interfaces make cutting ferrule 3,7 fixed with pressure roller 1 be one, with shape and horn mouth 9 identical and width and cutting ferrule 3,7 similar awl pieces 6 embed and are adhered to cutting ferrule 3, in the horn mouth 9 at 7 interface surface places, at cutting ferrule 3,7 and pressure roller 1 and awl piece 6 and pressure roller 1 between device have that its screw thread position scribbles bonding agent add fixing bolt 8, on the outer peripheral face of cutting ferrule 3,7 and awl piece 6, make the profile of tooth identical with press nips 5;
2. restorative procedure according to claim 1 is characterized in that: the angle that horn mouth became at cutting ferrule 3,7 interface surface places is 50 °～75 °.
