Description

Technical Field

[0001] The utility model belongs to the technical field of wool felt processing, and in particular relates to a wool gasket cutting tool. Background Art

[0002] Wool felt is made of wool. Wool has both soft and tough properties, good fiber elasticity, comfortable touch, and good restoreability. After being folded, wool felt products can quickly return to their original shape and are not easily deformed. In addition, its fiber structure can be tightly entangled. Its strong and tough properties do not require knitting, sewing, and other processing, and can be formed in one piece.

[0003] Wool washers are annular washers cut from wool felt. They are widely used in various industries such as machinery, electronics, mining, musical instruments, sports equipment, furniture, automobiles, aircraft, and ships. They have multiple functions such as sealing and dustproofing, shockproofing and buffering, thermal insulation, oil absorption and storage, filtration, padding, sound insulation, etc. They have good compressibility and resilience, and small permanent deformation. At present, when cutting wool felt, laser cutting machines are mostly used. However, laser cutting machines not only have high purchase costs, which can easily cost hundreds of thousands or even millions, but also have high maintenance costs, which increases the economic cost of the enterprise. In addition, laser cutting machines can only cut out one wool washer at a time, and the production efficiency is low. If wool washers of other specifications need to be cut, the parameters need to be reset, which is troublesome to operate and the steps are cumbersome.

[0004] Therefore, a wool gasket cutting tool is urgently needed to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the utility model provides a wool gasket cutting tool, including a workbench, a fixed bracket, a screw rod, a guide rod, a mounting plate and a servo motor. The fixed bracket is fixed above the workbench, and bearing seats are arranged at the front and rear ends of the right top of the fixed bracket. The screw rod is arranged on the right side of the top of the fixed bracket, and the front and rear ends of the screw rod are rotatably connected to the two bearing seats on the fixed bracket respectively. The guide rod is fixedly connected to the left side of the top of the fixed bracket, and the guide rod is opposite to the screw rod on the left and right sides. The mounting plate is arranged on the top of the fixed bracket, and the screw rod and the guide rod pass through the left and right ends of the mounting plate respectively. The mounting plate is slidably connected to the screw rod through the nut pair of the screw rod. A plurality of hydraulic cylinders are evenly fixed on the bottom of the mounting plate, and a plurality of hydraulic oil cylinders are arranged on the bottom of the mounting plate. The cylinders are located in the same vertical plane, and the hydraulic cylinder has the function of realizing the combined action of piston rod rotation and extension. The piston rod of each hydraulic cylinder is detachably connected with an annular knife die, and the annular knife die comprises an inner annular knife and an outer annular knife. The inner annular knife and the outer annular knife are nested together inside and outside, and the center of the inner annular knife coincides with the center of the outer annular knife. The bottoms of the inner annular knife and the outer annular knife are both provided with blades, and the blades at the bottoms of the inner annular knife and the outer annular knife are at the same height. The annular knife die has various specifications according to the different diameters of the inner annular knife and the outer annular knife. Workers can replace annular knife dies of different specifications according to actual requirements on site so as to cut wool washers of different diameters; the servo motor is fixedly arranged on a fixed bracket, and the output shaft of the servo motor is connected to the screw drive.

[0006] Optionally, a bump is provided at the end of the piston rod of the hydraulic cylinder, a groove matching the bump of the piston rod is provided at the top of the annular cutting die, and bolt holes are provided on the groove and the bump.

[0007] Specifically, the protrusion of the piston rod and the groove of the annular cutting die can be fixedly connected together by bolts and nuts.

[0008] Optionally, the bottom of the workbench is provided with legs.

[0009] Optionally, a drawer is provided under the workbench.

[0010] Specifically, every time a wool felt is processed, some wool fibers and other debris will be generated at the bottom and around it. The drawer can be opened to sweep the wool debris into the drawer and collect them. After all the processing is completed, they can be cleaned up together.

[0011] Optionally, a support frame is provided at the bottom of the servo motor, and the support frame is fixedly connected to the fixed bracket.

[0013] The working principle of the utility model is that the worker first replaces the annular cutting die of corresponding specifications according to the on-site requirements, and then fixes the annular cutting die and the piston rod of the hydraulic cylinder with bolts and nuts, and then spreads the 1m×1m wool felt on the workbench, starts the servo motor, drives the screw to rotate, and then moves the mounting plate from front to back along the guide rod. The operating parameters of the servo motor can be set so that its output shaft stops after each rotation of a certain angle. At this time, the hydraulic cylinder is controlled to drive the piston rod to spin downward to perform rotational cutting on the wool felt, so that multiple wool washers of different specifications or the same specifications can be cut at one time. After the cutting is completed, the hydraulic cylinder retracts the piston rod, and the servo motor drives the output shaft to continue to rotate, and the next round of cutting operation starts after rotating a certain angle.
