Problems solved by technology
Especially when the shape of the strip is not good, the trimming motor will trip due to excessive speed deviation
From on-site analysis, it is found that the outer diameter of the solid rubber spacer ring installed symmetrically up and down on the edge trimmer blade is too large and the hardness is uneven, and the strip steel is pressed too tightly or the longitudinal force of the strip steel is uneven, that is, the rubber spacer ring has an impact on the strip steel. The pressure is unstable, which causes the speed of the trimming machine and the strip steel to be out of sync. The motor of the trimming machine is always in the state of alternating power generation and electric power, and the heat generated by the motor increases.
[0004] At present, the problem of power trip is mainly considered from the aspect of modifying the transmission parameters of the drive motor, but it cannot completely solve the problem

Embodiment Construction
[0022] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.
[0023] The entrance of the trimming machine is an uncoiler, and the exit is a coiler, both of which are driven by frequency converters to ensure that the strip runs at a constant speed. The cutter shaft of the trimming machine is composed of upper and lower fixed cylinders, with blades at both ends, and rubber spacers with the same outer diameter as the blades in the middle, which are used to stabilize the strip steel, as shown in Figure (1).
[0024] When the cutter shaft adjustment motor adjusts the overlapping amount of the upper and lower blades according to the thickness of the strip, the upper and lower rubber spacers will squeeze the running strip in the middle. Due to the long-term operation of the unit, the rubber spacers will be in contact with the strip Horizontal and longitudina...

The invention discloses a strip steel trimmer. The strip steel trimmer comprises cutter shafts and cutting blades arranged at the two ends of the cutter shafts, distance rings sleeving the cutter shafts are arranged between the cutting blades located at the two ends of the cutter shafts, the distance rings are the multiple inflating type distance rings which sleeve the cutter shafts, and cavitiesof the adjacent inflating type distance rings are connected through air pipes so that the air pressure between the distance rings can be the same. The strip steel trimmer has the advantages that stripsteel can be stabilized better through the inflating type distance rings communicating with one another, the strip steel shaking phenomenon is reduced, the tripping frequency and stopping frequency of a motor of the trimmer are decreased, equipment impact damage caused by equipment stopping is reduced, accordingly, the stability of the strip steel during high-speed operation is ensured, the trimming quality of a finished silicon steel reel is improved, the rejected rate is decreased, and the rate of finished products is increased.
Description
technical field [0001] The invention relates to the technical field of steel processing, in particular to a strip trimming machine. Background technique [0002] As shown in Figure (1), in the prior art, the entrance of the trimming machine is an uncoiler, and the exit is a coiler, both of which are driven by frequency converters to ensure that the strip runs at a constant speed. The cutter shaft of the trimming machine is composed of two fixed cylinders, the two ends are blades, and the middle is a rubber spacer ring with the same outer diameter as the blade, which is used to stabilize the strip steel. A groove is set on the side wall of the spacer ring for Fix the spacer ring and the cutter shaft relatively together. [0003] The trimming machine of the silicon steel recoiling unit often has a motor current exceeding the rated current, and the heat generated by the motor increases. The faster the running speed of the unit, the greater the temperature rise of the motor, a...
