Description

Technical Field

[0001] The utility model relates to the technical field of slitting equipment, in particular to a knife shaft deformation correction device. Background Art

[0002] The trimming knife is the core device of the slitting equipment. Its precision plays a vital role in the quality of the edge of the cut material. The runout of the cutter disc directly leads to quality defects in the edge of the cut material. The current slitting equipment mainly adopts two slitting forms: moving knife and static knife. The utility model is mainly aimed at the correction of the moving knife shaft. The main function is to correct the radial runout and end face runout accuracy of the cutter shaft through physical methods, improve the accuracy of the trimming knife blade, improve the trimming quality, and thus improve the product quality. The slitting knife was limited by factors such as the trimming width at the beginning of its design. The design was relatively small, resulting in a small diameter of the cutter shaft. It is easy to deform after being subjected to external force. Each slitting equipment is generally equipped with 3 to 5 cutter heads. Therefore, the number of cutter heads of the equipment is large. A new cutter shaft must be replaced after each deformation, which will greatly increase the production cost.

[0003] The purpose of this utility model is to provide a correction device, through which the cutter shaft can be restored to the accuracy of a new shaft after correction, thereby reducing production costs. The utility model can also correct online, saving the process of disassembling and assembling the cutter shaft and reducing maintenance time. Utility Model Content

[0024] Example

[0025] Combine Figures 1-6 The utility model provides a tool shaft deformation correction device. During the production process, if the tool disc swings visibly or there are edge quality problems such as ruffles, the end face runout and radial runout are corrected using a dial indicator.

[0027] The side of the cutter disc 6 away from the cutter disc shaft 7 is connected to the cutter disc pressure plate shaft 4 through the circular cutter pressure plate bolt 5.

[0028] The first cutter disc fixing component 1 is sleeved on the cutter disc pressure plate shaft 4. The first cutter disc fixing component 1 is provided with a first connecting port 13 and a second connecting port 14 provided below the first connecting port 13. The first connecting port 13 is connected to the correction component 3, and the second connecting port 14 is aligned with the circular cutter pressure plate bolt 5.

The top of the mounting frame 12 is provided with a threaded hole adapted to the third connection port 15. The third connection port 15 and the threaded hole are connected by a first bolt 8.

[0030] One end of the correction component 3 passes through the first connection port 13 and is in mechanical contact with the second cutter head fixing component 2 , so as to apply a reaction force to the cutter head shaft 7 .

[0031] This embodiment adopts a tool shaft deformation correction device of the above structure. First, measure the end face of the cutter disc 6, find the lowest point, mark it, and then measure the radial surface of the cutter disc 6 to find the highest point. The intersection of the two points is the correction reference point; use the first cutter disc fixing component 1 to insert into the cutter disc pressure plate shaft 4 of the moving knife structure, align the second connecting port 14 with the circular knife pressure plate bolt 5 of the moving knife structure, and place the second cutter disc fixing component 2 on the opposite side of the cutter disc 6 of the moving knife structure.

The correction component 3 is adjusted to an appropriate force (a torque wrench can be used here to control the force). The reaction force is used to slightly deform the cutter disc shaft 7 of the moving knife structure until the accuracy of the cutter disc 6 reaches the standard accuracy. This embodiment can be installed on an existing moving knife device, saving the process of disassembling and assembling the cutter shaft.
