Abstract
The invention relates to a method for connecting broken thin strip steels on a continuous production line, belonging to the technical field of cold rolling plate strip rolling. The method comprises the following steps of: overlapping a forward strip steel downwardly and a backward strip steel upwardly after processing the fractures of the strip steels; controlling the overlap joint length within 500-600 mm; punching cross holes along the width direction of the strip steel by using a cross punching tool, wherein the distance between the cross hole and the edge part of the strip steel is 80-100 mm; the centre distance is 150-250 mm; the cross holes are uniformly distributed along the width direction; and the cross holes are in 40-60*40-60 mm in size; averagely distributing three rows of cross holes along the rolling direction in the overlap joint region; punching the middle row at intervals; after punching, upwardly folding and tightly pressing four triangular strip steels formed by each cross hole; and spot welding various angular point positions. The method for connecting the broken thin strip steels on the continuous production line disclosed by the invention has the advantages that: the connection problem after the thin strip steels are broken is solved in a mechanical manner; the method is simple for operation and high in connection quality; and the disadvantages of high operation difficulty and poor welding quality in the traditional welding are overcome.
Description
Technical field
The invention belongs to the cold rolled sheet rolling technical field, particularly relate to a kind of method of attachment that on tinuous production, approaches specification band steel broken belt.
Background technology
In the flat cold-rolled sheet production line, method of attachment conventional behind the broken belt is manual welding.But in the practical operation, the band steel of thickness≤0.8mm, there is following problem in manual welding: 1. be with steel thin, welding zone takes place and burns phenomenon in welding process easily.2. weldquality is poor, and broken belt accident again takes place easily.3. operation easier is high, receives the influence of many-sided factors such as place and welder's experience.Therefore, the connection behind the strip steel broken belt has become the major reason that restriction product line resumes production fast.Seeking a kind of is the problem of needing solution badly to simple, the firm method of attachment behind the strip steel broken belt.
Summary of the invention
The object of the present invention is to provide the method for attachment of lock eliminant behind a kind of strip steel broken belt, it is big to have overcome the operation easier that traditional welding exists, the shortcoming of welding quality difference; Main solve connectivity problem behind the thin specification band steel broken belt through mechanical system, simple to operate, be connected firmly, quality of connection is high.
After band steel fracture disposed, the band steel that will move ahead was following, and back row band steel stacks last; The lap of splice is controlled at 500mm～600mm.Use cross wide to dashing " cross bore " towards instrument (comprising upper trimming die, following punch die and cross drift) along the band steel, " cross bore " apart from the 80～100mm of strip edge portion, hole center distance 150mm～250mm is along wide to even distribution.Cross bore size: 40～60 * 40～60mm.In the overlap joint zone, along rolling to being evenly distributed three rows' " cross bore ", middle row's punching at interval.
After punching was accomplished, four " trigonum " band steel that each " cross bore " district is formed upwards turned down compacting, each angle point place spot welding.
Of the present inventionly be that a little this connected mode is easy and simple to handle, the operating time is 50% of a general welding operation method.Connected mode mainly is to utilize the mode of the lock knot of specific purpose tool formation, to the no specific (special) requirements of operation; Be connected firmly, can guarantee to be with steel broken belt not when the logical plate of bending repeatedly.
Description of drawings
Fig. 1 is an operation chart of the present invention.Wherein, behind the broken belt band steel 1, band steel fracture handle 2, the stack of band steel, on four jiaos of cross bore 3, cross bore, turn over pressing, angle point spot welding 4.
The specific embodiment
Be example with 0.6 * 1250mm band steel below, the practical implementation method of this method of attachment is described.
With broken belt take the lead the district dispose.The band steel that moves ahead deposits, and back row band steel is put and stacked overlap length 600mm.Punch operation: along rolling direction, each edge, 150mm place is wide to respectively dashing row's " cross bore " taking the lead apart from both sides, and every row's " cross bore " is lateral opening apart from the 100mm of strip edge portion, pitch of holes 210mm.Wide to dashing the 3rd row's " cross bore " along the band steel at two row's " cross bore " middle parts, new hole is positioned at the cross center of two rounds of punching press.
Claims (4)
1. the method for attachment of a thin specification band steel broken belt on tinuous production is characterized in that, after band steel fracture disposed, the band steel that will move ahead was following, and back row band steel stacks last; The lap of splice is controlled at 500mm～600mm; Use cross wide to dashing " cross bore " towards instrument along the band steel, " cross bore " apart from the 80～100mm of strip edge portion, hole center distance 150mm～250mm is along wide to even distribution; After punching was accomplished, four " trigonum " band steel that each " cross bore " district is formed upwards turned down compacting, each angle point place spot welding.
2. the method for attachment that on tinuous production, approaches specification band steel broken belt according to claim 1 is characterized in that cross bore size: 40～60 * 40～60mm.
3. the method for attachment that on tinuous production, approaches specification band steel broken belt according to claim 1 is characterized in that, in the overlap joint zone, along rolling to being evenly distributed three rows' " cross bore ", middle one arranges punching at interval.
4. the method for attachment that on tinuous production, approaches specification band steel broken belt according to claim 1 is characterized in that described cross comprises upper trimming die towards instrument, following punch die and cross drift.
