TECHNICAL FIELD
[0001] The utility model relates to the field of flywheel, more specifically, it relates to a flywheel counterweight structure. BACKGROUND
[0002] The flywheel used in the punch press is one of the core components of the stamping equipment, and its main function is to store and release kinetic energy to ensure that the punch press provides stable energy in short-time and high-intensity stamping actions. When the punch press is working, the motor continuously provides power, but the stamping action is intermittent (instantaneous high energy demand). The flywheel stores the energy output by the motor through rotational inertia and releases kinetic energy at the moment of stamping to avoid the motor directly bearing impact load, protect the equipment and improve energy efficiency. The energy stored by the flywheel can be reused to reduce the energy consumption of frequent start-stop of the motor, and is suitable for high-load working conditions of large-tonnage punch presses.
[0003] The main body of the flywheel: thick disc or spoke structure, mass concentrated in the rim to increase the moment of inertia; The connection mode of the flywheel: connected with the motor shaft and the clutch through the keyway or flange, and part of the flywheel integrates the clutch-brake system; The surface treatment of the flywheel: the rim may be designed with heat dissipation grooves or balance holes to reduce thermal deformation and vibration during high-speed rotation.
[0004] In the use of the punch press, there are many benefits to adjusting the weight of the flywheel, such as:
[0005] Adapt to different working conditions, increase the weight to improve the energy storage capacity of the flywheel, suitable for short-time stamping with high energy demand, and reduce the weight to facilitate fast start-stop, suitable for high-frequency low-energy operation;
[0006] Match the load change: for example, when the punch press processes materials of different thicknesses, adjust the flywheel inertia to match the impact energy to avoid "overload" or "energy deficiency";
[0007] Energy saving and efficiency improvement: reasonable configuration of flywheel weight can reduce the energy consumption of frequent motor speed regulation, especially in intermittent operation (such as stamping and forging);
[0008] Improve operation precision: suppress speed fluctuation by flywheel counterweight to ensure processing precision.
[0009] However, the existing flywheel is often fixed in weight, and it is relatively inconvenient to prepare many flywheels of different specifications to adjust the weight of the flywheel.
[0010] Therefore, a new scheme is needed to solve this problem. UTILITY MODEL CONTENTS
[0011] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a flywheel counterweight structure.

[0013] The utility model further sets up: the weight ring is equipped with a plurality of weight reduction holes, and the weight ring is distinguished different weight through the number and / or area of the weight reduction hole.
[0014] The utility model further sets up: the center wheel and weight ring are detachably fixed through a plurality of long bolts, and the long bolt is along the radial setting of center wheel, and the outer peripheral wall of center wheel is equipped with a plurality of thread holes, and the long bolt is radially passed through weight ring and is screwed into the thread hole.
[0015] The utility model further sets up: the center wheel and weight ring are equipped with assembly shell.
[0016] The utility model further sets up: the assembly shell includes two shell bodies located at the both sides of center wheel respectively, and the two shell bodies are detachably connected, and the weight ring is equipped with a plurality of structure reinforcing holes, and the shell body is equipped with a plurality of support columns passing through the structure reinforcing hole.
[0017] The utility model further sets up: the two shell bodies are fixed through short bolt and nut, and the short bolt passes through the support column on two shell bodies.
[0018] In conclusion, the utility model has the following beneficial effects: different weight distinguishes different weight ring, and the weight ring of different weight is installed on the center wheel, so that the weight of flywheel is changed, so it is not necessary to prepare different weight flywheel, and only need to change the weight ring of different weight specification to change the weight of flywheel, so as to adapt to different processing environment, and compared with preparing the whole flywheel of different weight, the weight ring of different weight occupies smaller space and has smaller cost, and when changing the weight of flywheel, the whole flywheel does not need to be disassembled, and only need to change the weight ring in flywheel weight structure, so it is more convenient.
