Description
Technical Field
The utility model relates to a metal coil stock production technical field, especially a decoiler machine.
Background
The uncoiling machine adopts a mode that upper and lower pressing rollers press metal plates to flatten the uncoiled and bent plates, and in order to meet the requirements of the metal plates with different thicknesses, the distance between the upper and lower pressing rollers is adjusted in a lifting pressing roller mode commonly used at present to meet the requirements of the metal plates with different thicknesses, such as a cold-rolled steel coil uncoiling machine with adjustable height disclosed in the grant publication No. CN213591444U and an improved intelligent uncoiling machine disclosed in the grant publication No. CN 210160182U. Although the two decoiling machines can adjust the height of the upper press roll, the buffer and the protection device are lacked between the upper press roll and the lower press roll, and the friction between the metal plate and the press roll is increased due to overlarge pressure between the upper press roll and the lower press roll, so that the transmission is difficult, and even the surface of the metal plate is damaged; too low a pressure between the upper press roll and the lower press roll may result in insufficient flattening of the metal sheet.
Disclosure of Invention
The utility model aims to solve the technical problem that a decoiler machine is provided, can play buffering and guard action to the metal sheet when the compression roller pushes down.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides an open flat-bed machine, includes compression roller frame and lower compression roller frame, is equipped with the elevating gear who is used for driving it and reciprocates in the upper end of last compression roller frame, is equipped with the mounting groove in the inboard of last compression roller frame, is equipped with vertical slide bar at the mounting groove internal fixation, is equipped with the sliding block on the slide bar, centraxonial both ends fixed connection of compression roller is on the sliding block, the cover is equipped with pressure spring in the outside of slide bar, pressure spring's one end is connected in the top of mounting groove inner chamber, the other end is connected in the top of sliding block.
Preferably, the device further comprises a protection mechanism, the protection mechanism comprises a bulge arranged on the upper surface of the lower compression roller frame, an adjusting bolt corresponding to the bulge is arranged on the bottom surface of the upper compression roller frame, and the adjusting bolt is in threaded connection with the upper compression roller frame.
Preferably, the protection mechanism is provided with four groups which are respectively arranged at four corners of the upper compression roller frame and the lower compression roller frame.
Preferably, the lifting device is a hydraulic cylinder.
The utility model provides a decoiler, which is provided with a compression spring, so that an upper compression roller can slowly and gradually apply pressure to a metal plate in the descending process; and a protection mechanism is arranged to limit the maximum descending position of the upper compression roller frame, so that the phenomenon that the upper compression roller frame descends too much and the compression roller causes transition compression on the metal plate is prevented.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic side view of the present invention;
fig. 3 is an enlarged schematic view of a portion a of fig. 2 according to the present invention;
fig. 4 is a schematic structural view of the present invention in use.
Detailed Description
As shown in fig. 1-3, a decoiler comprises an upper roll frame 2 and a lower roll frame 1, wherein a lifting device 9 for driving the upper roll frame 2 to move up and down is arranged at the upper end of the upper roll frame, a mounting groove 3 is arranged on the inner side of the upper roll frame 2, a vertical slide rod 4 is fixedly arranged in the mounting groove 3, a slide block 6 is arranged on the slide rod 4, two ends of a middle shaft of a press roll 10 are fixedly connected onto the slide block 6, a compression spring 5 is sleeved on the outer side of the slide rod 4, one end of the compression spring 5 is connected to the top of an inner cavity of the mounting groove 3, and the other end of the compression spring is connected to the top of the slide block 6. And a pressing spring is arranged, so that the upper pressing roll frame 2 can press the metal plate by the pressing roll 7 in the descending process.
Preferably, the device further comprises a protection mechanism, the protection mechanism comprises a protrusion 7 arranged on the upper surface of the lower compression roller frame 1, an adjusting bolt 8 corresponding to the protrusion 7 is arranged on the bottom surface of the upper compression roller frame 2, and the adjusting bolt 8 is in threaded connection with the upper compression roller frame 2. Adjust the length of adjusting bolt 8 through rotatory adjusting bolt 8 to the distance between last compression roller frame 2 and the lower compression roller frame 1 when adjusting protruding 7 and adjusting bolt 8 and contacting, the compression of 5 is more the distance is less, and the pressure that protruding 7 produced the metal sheet is big more. The setting of protection mechanism has realized the regulation of pressure size, can prevent simultaneously that the compression roller transition from oppressing the metal sheet, can play limiting displacement to last compression roller.
Preferably, the protection mechanism is provided with four groups which are respectively arranged at four corners of the upper compression roller frame 2 and the lower compression roller frame 1.
Preferably, the lifting device 9 is a hydraulic cylinder.
When the device is used, the upper compression roller frame 2 is slowly lowered, when the compression roller 10 is just contacted with a metal plate but does not generate pressure, the spring does not deform as shown in figure 1, then the upper compression roller 2 is continuously lowered, the compression spring 5 deforms and is compressed from the beginning, meanwhile, the compression roller 10 generates downward pressure on the metal plate until the protrusion 7 is contacted with the adjusting bolt 8 as shown in figure 4, at the moment, the upper compression roller frame 2 does not descend any more, and the pressure value is also a fixed value. The accessible rotates adjusting bolt 8's length and comes pressure regulation to can play limiting displacement to last compression roller frame 2, prevent the transition and descend, cause the transition oppression.
The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and equivalents including technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
