Problems solved by technology

The invention patent of Chinese patent No. ZL200420064892.3 discloses an electric screw press. The motor drives the large gear through the small gear to perform spiral motion, and the spiral pair converts the spiral motion of the large gear and the screw into the linear motion of the slider. The motor is connected to the pinion, the motor shaft is subjected to a large impact force, the motor shaft is prone to fatigue damage, and it is not easy to maintain the concentricity of the motor shaft and the gear shaft; lack of precise pressure control measures

Embodiment 2

[0031] For a large-scale energy-saving numerical control screw press with a large pulley, the motor 1 and the pinion 31 are on the same side, which can effectively prevent the belt from being too long. The shape of the right vertical arm 5 of this kind of structure is different from embodiment 1, is straight.

[0032] In order to avoid the wear and tear of the pinion due to long-term work and affect the service life of the pinion, the pinion shaft can be composed of a pinion 31 , a transmission shaft 32 and a flat key 33 . There can be 2 or 3 flat keys 33. After a part of the pinion 31 is worn, the position of the pinion 31 can be rotatably adjusted to effectively increase the life of the pinion 31.

[0033] In order to improve production efficiency, a moment of inertia adjustment ring 34 is added at the end of the large gear 17, and the moment of inertia adjustment ring 34 is fastened to the end of the large gear 17 to adjust the moment of inertia and achieve the purpose of a...

Embodiment 3

[0035] In order to avoid wear and tear of the pinion due to long-term work and affect the service life of the pinion, the pinion shaft can be composed of a segmented pinion 35, a drive shaft 32 and a flat key 33. The split pinion 35 is connected with the power transmission shaft 32 through the flat key 33 in two sections. When used for a period of time, after a part of the segmented pinion 35 is worn out, the position of the segmented pinion 35 can be adjusted by exchanging the upper and lower parts, effectively increasing the life of the segmented pinion 35 . All the other are with embodiment 1.

[0036] In order to improve production efficiency, a moment of inertia adjustment ring 34 is added in the bull gear 17, and the moment of inertia adjustment ring 34 is fastened in the bull gear 17. The moment of inertia adjusting ring 34 is an integral type or a combined type, and the combined type is composed of multiple pieces.

Abstract

The invention discloses an energy-saving numerical control screw press and a control method thereof and belongs to the field of mechanical industrial equipment. An upper drive system comprises a belt drive, a gear drive and a semi-gearbox, a transmission case, a belt tension adjustor and a belt planeness adjustor for fixation, and a tonnage instrument (30) is mounted on the screw press (19), and the output end of the tonnage instrument (30) is connected with a control system. The control method comprises the following steps: by adding the tonnage instrument, inputting a pressure setting value into the control system, the control system comparing the difference of the pressure setting value with the a pressure real-time monitoring value, calculating according to a formula, adjusting a motor rotation speed, and realizing accurate control of the pressure. Compared with the prior art, the invention can not only ensure the accurate control of the pressure, but also effectively protect the motor shaft.

Description

technical field [0001] The invention provides an energy-saving numerical control screw press and a control method, which belong to the field of mechanical industrial equipment. Background technique [0002] The Chinese patent number is ZL200520125153.5, and the invention patent titled CNC screw press discloses a screw press driven by a switched reluctance motor, and its large gear and the screw perform rotational motion. The invention patent of Chinese patent No. ZL200420064892.3 discloses an electric screw press. The motor drives the large gear through the small gear to perform spiral motion, and the spiral pair converts the spiral motion of the large gear and the screw into the linear motion of the slider. The motor is connected to the pinion, the motor shaft is subjected to a large impact force, the motor shaft is prone to fatigue damage, and it is not easy to keep the motor shaft and the gear shaft concentric; there is a lack of precise pressure control measures.
