Abstract
The utility model discloses a guiding device for hollow guide rail cold bend rolling which comprises a mounting base seat. The guiding device for the hollow guide rail cold bend rolling is characterized in that a movable groove is installed on the mounting base seat, two sliding seats which move in a relative mode are installed inside the movable groove, a supporting shaft is arranged on each of the two sliding seats, and each supporting shaft is provided with a guiding roller through a rolling bearing, the guiding rollers are used for clamping a hollow guide rail. The guiding device for the hollow guide rail cold bend rolling can be used to provide guidance for a rolling plate during a hollow guide rail cold bend rolling process, and therefore certain straightness of the rolling plate can be maintained, the rolling plate can pass through various rolling moulds step by step, and working efficiency and product quality of the hollow guide rail cold bend rolling can be greatly improved.
Description
Technical field
The utility model relates to the rolling guider of a kind of hollow guide rail clod wash.
Background technology
Existingly be the rolling guide rail of clod wash for elevator is in service for counterweight provides the hollow guide rail of guiding, formed through multiple tracks pass mould clod wash roll forming by the roll bending steel.In the rolling operation of hollow guide rail clod wash of reality, assembly precision for the roll die group of special use has very high requirement, usually vertical linearity total deviation can not surpass 0.2mm from the first mould to last-pass die in requirement, the transverse horizontal deviation of per pass mould can not surpass 0.05mm, its objective is in order to ensure roll bending agonicly to pass through one by one roll die.
Yet actual conditions are owing to the internal stress of roll bending after the clod wash and the effect of elastic recovery, add and lack special guider, often can't keep certain linearity after roll bending is rolling through the clod wash of roll die step by step, and can wander off, cause often can't reliably entering down one mould by front one mould roll bending out, also can cause the roll bending deformed damaged when serious, mould can't normal operation.
Summary of the invention
The utility model purpose is: provide a kind of hollow guide rail clod wash rolling guider, this device can provide guiding for roll bending in the rolling operation process of hollow guide rail clod wash, can keep certain linearity to pass through step by step each roll die, improve the rolling operating efficiency of hollow guide rail clod wash and product quality with this.
The technical solution of the utility model is: the rolling guider of a kind of hollow guide rail clod wash, comprise mounting base, it is characterized in that described mounting base is provided with loose slot, described loose slot is built-in with relatively two sliding seats of activity, be fixed with respectively bolster on described two sliding seats, be equipped with guide roller in order to the clamping hollow guide rail by rolling bearing respectively on described two bolsters.
Further preferred, described in the utility model on the mounting base corresponding each sliding seat be separately installed with an adjusting screw(rod) that is used for regulating this sliding seat displacement, the displacement of the rotation realization sliding seat (3) of the adjusting screw cooperation adjusting screw(rod) that described every adjusting screw(rod) and corresponding sliding seat are provided with.The rolling guider of this hollow guide rail clod wash that the utility model provides mainly cooperates roll die to use, when needs carry out the rolling operation of clod wash of hollow guide rail, can between two adjacent roll dies, the utility model be set, and regulate the spacing of two guide rollers according to required hollow guide rail size.After curving the guiding of type roll bending out by two guide rollers by front one mold cold, just can agonic enter down one mould and continue rolling like this.
The utility model has the advantages that:
The rolling guider of this hollow guide rail clod wash that the utility model provides can provide guiding for roll bending in the rolling operation process of hollow guide rail clod wash, make it keep certain linearity to pass through step by step each roll die, greatly improve the rolling operating efficiency of hollow guide rail clod wash and product quality with this.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural front view of the present utility model (band portion is analysed and observe);
Fig. 2 is the side view of Fig. 1.
Wherein: 1, mounting base; 2, loose slot; 3, sliding seat; 4, bolster; 5, rolling bearing; 6, guide roller; 7, adjusting screw(rod); 8, hollow guide rail.
The specific embodiment
Embodiment: in conjunction with Fig. 1, shown in Figure 2, the rolling guider of this hollow guide rail clod wash that the utility model provides, it has mounting base 1, described mounting base 1 is provided with loose slot 2, described loose slot 2 is built-in with relatively two sliding seats 3 of activity, be fixed with respectively bolster 4 on described two sliding seats 3, be equipped with guide roller 6 in order to clamping hollow guide rail 8 by rolling bearing 5 respectively on described two bolsters 4.
Simultaneously corresponding each sliding seat 3 is separately installed with an adjusting screw(rod) 7 that is used for regulating these sliding seat 3 displacements on the mounting base 1 described in the present embodiment, and described every adjusting screw(rod) (7) and corresponding sliding seat (3) are provided with the displacement of the rotation realization sliding seat (3) of screw cooperation adjusting screw(rod) (7).
The rolling guider of this hollow guide rail clod wash that the utility model provides mainly cooperates roll die to use, when needs carry out the rolling operation of clod wash of hollow guide rail 8, can between two adjacent roll dies, the utility model be set, and the spacing of regulating two guide rollers 6 according to required hollow guide rail 8 sizes.After curving the guiding of type roll bending out by two guide rollers 6 by front one mold cold, just can agonic enter down one mould and continue rolling like this.
Above-mentioned example only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
