Abstract
The utility model discloses a mandrel for a recoiling machine of a shearing machine, which can prevent gaps among cushion blocks from generating dents at the surface of a strip steel and can improve the surface quality of the strip steel. The mandrel for the recoiling machine of the shearing machine comprises a sector plate, an additional plate for the sector plate, and a jaw cushion block, wherein an external wedge block is arranged on the sector plate, and an additional cushion block and an additional wedge block which are used for filling the gaps are connected on the external wedge block through bolts. The radian of the arc of the joint between the jaw cushion block and the strip steel is 70 degrees. The mandrel has the structure that the additional cushion block and the additional wedge block are arranged on the original external wedge block on the sector plate so as to fill the gaps among the original cushion blocks, eliminate dents on a steel plate caused by the cushion blocks of the mandrel and improve the surface quality of the strip steel. The mandrel realizes the smooth transition of the strip steel at the arc by changing the radian of the arc on the jaw cushion block of the mandrel, therefore, the surface quality of the strip steel is improved.
Description
Technical field
The utility model relates to a kind of cutter coiling machine mandrel.
Background technology
In stainless steel sheet strip production field finished product side cut bundling unit, shear line batch mandrel, can realize the strip coiling work of 508mm and two kinds of diameters of 610mm.Axle diameter is to realize by the method that installs the fanning strip add-in card in the mandrel appearance additional by 508mm to the transformation of 610mm, but axle diameter is under the situation of 610mm, exist 3 slits between fanning strip add-in card and the outer wedge, dent is brought to belt steel surface in these three slits when producing the strip steel, the surface quality of influence band steel.
In addition, because thick band steel in the process of batching with jaw, is with the cushion block of steel meeting and jaw to fit tightly, and when the second astragal steel is pressed onto the junction of the first astragal steel and jaw cushion block, has also produced and creased, the surface quality of influence band steel.
The utility model content
The utility model is in order to overcome weak point of the prior art, to provide a kind of and can prevent that the slit between cushion block from producing dent at belt steel surface, improving the cutter coiling machine mandrel of strip surface quality.
The utility model is achieved through the following technical solutions:
A kind of cutter coiling machine mandrel comprises fanning strip, fanning strip add-in card and jaw cushion block, and three outer wedges are installed on the described fanning strip, it is characterized in that, is connected with the additional cushion block and the additional wedge of filling chink on each outer wedge by bolt.
Described jaw cushion block is 70 degree with the radian of band steel junction circular arc.
The utlity model has following technique effect:
(1) mandrel of the present utility model punches on the wedge outside original fanning strip, by being installed, additional cushion block and additional wedge fill up the slit of original cushion block, make the outer surface of mandrel tightr, eliminate between the mandrel cushion block dent to steel plate, the strip surface quality of raising with this.
(2) by changing the radian of mandrel jaw cushion block circular arc, the band steel is seamlessly transitted at the circular arc place, when the band steel of the second layer is pressed onto ground floor band steel and jaw cushion block junction like this, also can seamlessly transit, alleviated jaw and creased, improved the surface quality of band steel.

Fig. 2 is the cutaway view of swelling state after the transformation of the utility model cutter coiling machine mandrel;
Fig. 3 is the schematic diagram of the utility model cutter coiling machine mandrel jaw cushion block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model cutter coiling machine mandrel is the improvement on prior art, the cutaway view of swelling state as shown in Figure 1 before cutter coiling machine mandrel was transformed, comprise fanning strip 5, fanning strip add-in card 1 and jaw cushion block 7, three outer wedges 4 are installed on the fanning strip 5, the cutaway view schematic diagram of swelling state as shown in Figure 2 after the transformation of cutter coiling machine mandrel, outside each, be connected with the additional cushion block 3 and the additional wedge 2 of filling chink on the wedge 4 by bolt, fuse after making each outer wedge 4 install additional cushion block 3 and additional wedge 2 additional, at axle diameter be fill up under the situation of 610mm and fanning strip between three slits, eliminate dent to steel plate.
Fig. 3 is the schematic diagram of the utility model cutter coiling machine mandrel jaw cushion block, creases in order to alleviate jaw, and described jaw cushion block 7 is 70 degree with the radian of band steel junction circular arc 6.The band steel is seamlessly transitted at the circular arc place, like this, when the band steel of the second layer is pressed onto ground floor band steel and jaw cushion block junction, also can seamlessly transit, alleviated jaw and creased.
Claims (2)
1. cutter coiling machine mandrel, comprise fanning strip, fanning strip add-in card and jaw cushion block, three outer wedges are installed on the described fanning strip, it is characterized in that, be connected with the additional cushion block and the additional wedge of filling chink on each outer wedge by bolt.
2. cutter coiling machine mandrel according to claim 1 is characterized in that, described jaw cushion block is 70 degree with the radian of band steel junction circular arc.
