Abstract
The invention discloses a double-crank punch press with high balance, which is characterized by comprising a punch press shell, a driving motor, a driving assembly, a crank assembly and a balance assembly, wherein the driving assembly is connected with the driving motor through a gear, the crank assembly is connected with the driving assembly through a driving belt, and the balance assembly is connected with the outer side of a crank.
Description
Technical Field
The invention belongs to the technical field of double-crank punching machines, and particularly relates to a double-crank punching machine with high balance.
Background
The punching machine is a punching machine, and is often used for forming product parts by carrying out various punching processes on plates in cooperation with a group of dies placed on the punching machine, and is widely applied to punching and forming of electronic, communication, electric appliance, furniture, vehicles, hardware parts and the like. When the punching machine works, the lower pressing block drives the upper die to move relative to the lower die, the rotary motion of the crank is converted into linear motion, and the motor drives the gear, the crank (or eccentric gear), the connecting rod and the like to operate, so that the rotary motion is converted into the up-and-down reciprocating motion of the sliding block, and the punching is realized. The punch press may be classified into a crank type punch press, a link type punch press, a toggle type punch press, a friction type punch press, a screw type punch press, a rack type punch press, a cam type punch press, etc. according to the difference of the driving mechanism.
The punch press mainly relies on the crank rotation to drive the connecting rod to do rotary reciprocating motion, and then drives the upper die to do up-down linear reciprocating motion. The crankshaft can generate inertial force and vibration during working, and the inertial force and vibration can directly lead to the stability of the whole device and even lead to dislocation of an upper die and a lower die.
The traditional punch press is in order to solve inertial force and vibrations on the bent axle and generally directly increase the crank on the bent axle, but increase the processing degree of difficulty of crank can greatly increased the bent axle, also can increase the inside assembly degree of difficulty of punch press and the connecting rod on the crank is damaged more easily.
Disclosure of Invention
The invention aims to solve the defects in the prior art, and provides a high-balance double-crank punch press which comprises a punch press shell, a driving motor, a driving assembly, a crank assembly and a balance assembly, wherein the punch press shell is rectangular and is arranged at the top of a punch press, a rectangular opening is arranged at the bottom of the punch press, the driving motor is arranged at the rear side outside the punch press shell, the driving assembly, the crank assembly and the balance assembly are arranged inside the punch press shell, the driving assembly is connected with the driving motor through a gear, the driving assembly comprises a gear, a driving shaft and a driving belt, the gear is connected with the driving shaft through a central mounting hole, the driving belt is arranged at the outer side of the driving shaft, the crank assembly is connected with the driving assembly through a driving belt, the crank assembly comprises a crank shaft, a hydraulic cylinder, a connecting rod and a pressing block, the crank shaft is a double-crank shaft, two cranks are arranged at two sides of the center line of the crank shaft, an extension crank shaft is arranged at the outer side of the middle of the crank shaft, the hydraulic cylinder comprises a cylinder body and a hydraulic shaft is connected with the top of the punch press shell, and the hydraulic shaft is connected with the crank. The top of connecting rod link to each other through articulated with the crank, the bottom of connecting rod link to each other with lower briquetting top, lower briquetting shape be the rectangle, lower briquetting establish the bottom opening at the punch press shell, balance subassembly link to each other with the cranked outside, balance subassembly includes balance area and balance axle, the balance axle establish the top inside the punch press shell, the balance area link to each other crank outside and balance axle.
Further, the gear is a helical gear.
Further, the driving belt is a metal belt, and the balance belt is a rubber belt.
Furthermore, the balance components are arranged at two ends of the crankshaft in a mirror image mode, and the balance shaft is suspended in the shell of the punching machine through the bearing seat.
Furthermore, the driving shaft is suspended in the shell of the punching machine through the suspended bearing seat.
The beneficial effects are that:
the balance assembly on both sides of the crankshaft reduces inertial force on the crankshaft by using a balance strap, connects the hydraulic cylinder to the crankshaft and shortens the connecting rod length to reduce vibration on the crankshaft and the connecting rod.
