Problems solved by technology

The above-mentioned balance structure schemes have their own characteristics, but they have one thing in common: the attitude of the slider is generally guaranteed by the constraints of the guide rail, so the ability to resist unbalanced load is not strong. , which requires high guiding precision and rigidity of the guide rail

Embodiment Construction

[0019] In order to obtain a good inertial force balance system, the high-speed precision press of the present invention adopts a combined balance scheme of a multi-bar balance mechanism and an auxiliary slide block arranged in the opposite direction. The crank drives the slider to reciprocate through the connecting rod. In order to balance the inertia force of the crank and the slider, the auxiliary slider and the auxiliary connecting rod are arranged in the opposite direction. In addition, two multi-rod branch chains are symmetrically arranged between the stamping slider and the bed. These two multi-rod branch chains are composed of two parallelogram mechanisms connected in series. The movement characteristics of the connecting rods of the parallelogram mechanism make the stamping slide The posture between the block and the bed remains unchanged. The reciprocating sliding block pushes the rods of the parallelogram mechanism to swing back and forth to both sides through two eq...

Abstract

The invention discloses a high-speed fine press having a structure that one end of a double-crank rod which has 180-degree phase difference is connected with a movable slide block by a main connecting rod, the other end of the double-crank rod is connected with an auxiliary slide block by an auxiliary connecting rod, same multiple-rod branch chains are symmetrically arranged at the left sides and the right sides of the movable slide block and a pressing slide block so as to connect the movable slide block and the pressing slide block together; the movable slide block makes reciprocation movement up and down under the drive of the double-crank rod and the main connecting rod so as to push a lower connecting rod, an upper connecting rod and a swinging block to swing at two sides through the push of push rods of the two multiple-rod branch chains, and the pressing slide block is further driven to do reciprocation movement up and down, and a workpiece is placed under the pressing slide block, therefore, the pressing processing of metal or nonmetal workpieces is completed. A parallelogram structure of a movable branch chain of the invention can ensure that the pressing slide block is always kept in a horizontal position and the force at horizontal direction of the pressing slide block can be balanced by a mechanism, thereby the capability of uneven loading resistance and the machining precision of the press are enhanced.

Description

technical field [0001] The invention is used in the field of high-speed stamping processing of metal or non-metal, in particular a high-speed precision press. Background technique [0002] The high-speed precision CNC press integrates high-speed precision stamping technology of machine tool manufacturing technology and key technologies such as mold technology, automatic control technology, and reliability technology. It has three basic characteristics of automation, high speed, and precision. High-efficiency precision machining of materials is widely used in high-tech fields such as aerospace, automobiles, power generation equipment, information, and home appliances. [0003] For ordinary presses, due to their low movement speed and small inertial force, they can be ignored, but for high-speed presses, due to their high operating speed, the inertial force caused by high speed is also large. Generally speaking, the inertial force and proportional to the square of the rotatio...
