Abstract
The invention relates to an eight-connecting-rod mechanical press. The mechanical press comprises a machine frame, a first crank, a second crank, a first connecting rod, a second connecting rod, an oscillating rod, a punch hammer connecting rod and a punch hammer, wherein the first crank and the second crank are connected with the machine frame through revolute pairs respectively; the first crank is connected with a servo motor, and is driven to rotate through the servo motor; the first connecting rod is connected with the first crank through a revolute pair; the second connecting rod is connected with the second crank through a revolute pair; the first connecting rod, the second connecting rod, the oscillating rod and the punch hammer connecting rod are connected with one another through a revolute pair at the same point; the oscillating rod is connected with the machine frame through a revolute pair; the tail end of the punch hammer connecting rod is connected with the punch hammer through a revolute pair; and the punch hammer is positioned in a fixed guide rail. In the mechanical press, diversified punch hammer pressure working curves can be acquired, and the problems of low flexibility and low punch forming quality of the conventional mechanical press are solved; simultaneously, the press has an extremely high force transfer property.
Description
Technical field
The present invention relates to not have the metal forming process equipment of cutting, specifically, relate to a kind of punching machine.
Background technology
At the metal forming manufacture field, particularly in sheet-metal press working, moulding, thin plate drawing process, hydraulic press machine and mechanical press are two kinds of main equipments.Hydraulic press machine production efficiency is low, hydraulic system maintenance is difficult and cost is high.Traditional mechanical press can not obtain the pressure working curve of user according to different processing technology needs, the inherent shortcoming that this forcing press lacks " flexibility " has hindered the further raising of Sheet Metal Forming Technology level, thereby is difficult to satisfy the requirement of high-quality stamping press.In recent years, the mechanical press that servomotor directly drives has appearred, as the wild company of day Home Network link lever press, Japanese Xiao Song HF series forcing press, Ohio, USA university duplex bar forcing press, Qiqihar second lathe group forcing press, this press structure form and standard machinery forcing press are basic identical, only change common electric machine into servomotor, can improve the speed characteristics and the dynamic performance of slide block by the input of regulating servomotor, application is wider.
Summary of the invention
The objective of the invention is to deficiencies such as metal forming is low with inefficiency, the Forming Quality that forcing press exists at having now, " flexibility " difference, the invention provides a kind of eight connecting rod punching machines, this forcing press is driven by servomotor, can obtain diversified block stamp pressure working curve, satisfy the requirement of high-quality stamping press.
Technical scheme of the present invention is: a kind of eight connecting rod punching machines, described forcing press comprises frame, first crank, second crank, first connecting rod, second connecting rod, fork, block stamp connecting rod and block stamp, and first crank is connected by revolute pair with frame respectively with second crank; First crank is connected with servomotor, and drives the rotation of first crank by servomotor; First connecting rod is connected by revolute pair with first crank, and second connecting rod is connected by revolute pair with second crank, and first connecting rod, second connecting rod, fork and block stamp connecting rod are connected by revolute pair in same point; Fork is connected with frame by revolute pair, and the end of block stamp connecting rod is connected with block stamp by revolute pair, and block stamp is within the fixed guide.
Beneficial effect of the present invention is: the present invention can obtain diversified block stamp pressure working curve, and it is poor to have solved traditional punching machine " flexibility ", the low-quality problem of punch forming; Simultaneously, forcing press has good force-transfer characteristic.
Description of drawings
Fig. 1 is the structural representation of the specific embodiment of the invention.
The specific embodiment
Specific embodiments of the invention as shown in Figure 1, a kind of eight connecting rod punching machines, described forcing press comprises that frame 1, first crank 2, second crank 4, first connecting rod 3, second connecting rod 5, triangle fork 6, block stamp connecting rod 7 and block stamp 8, the first cranks 2 and second crank 4 are connected by revolute pair with frame 1 respectively; First crank 2 is connected with servomotor, and drives 2 rotations of first crank by servomotor; First connecting rod 3 is connected by revolute pair with first crank 2, and second connecting rod 5 is connected by revolute pair with second crank 4, and first connecting rod 3, second connecting rod 5, fork 6 and block stamp connecting rod 7 are connected by revolute pair in same point; Fork 6 is connected with frame 1 by revolute pair, and the end of block stamp connecting rod 7 is connected with block stamp 8 by revolute pair, and block stamp 8 is within the fixed guide.
During work, first crank 2 rotates under servomotor drives, under the drive of first crank 2, first connecting rod 3 is done plane motion, and second crank 4 is done circumference and rotated, and second connecting rod 5 is done plane motion, fork 6 is done reciprocally swinging around frame 1, and block stamp connecting rod 7 is done complicated plane motion; In this process, block stamp 8 also setting in motion under the effect of block stamp connecting rod 7, because it is spacing to be subjected to the horizontal direction of guide rail, and block stamp connecting rod 7 is hinged again with block stamp 8, so block stamp 8 can only punching press up and down in guide rail.
