Abstract
The utility model relates to an eight-connecting rod mechanical press, comprising a frame, a first crank, a second crank, a first connecting rod, a second connecting rod, a swing rod, a punch hammer connecting rod and a punch hammer, wherein the first crank and the second crank are respectively connected with the frame via revolute pairs. The first crank is connected with a servo motor, which drives the first crank to rotate. The first connecting rod and the first crank are connected via a revolute pair, and the second connecting rod and the second crank are connected via a revolute pair. The first connecting rod, the second connecting rod, the swing rod and the punch hammer connecting rod are connected at the same point via a revolute pair. The swing rod is connected with the frame via a revolute pair, and the end of the punch hammer connecting rod is connected with the punch hammer via a revolute pair. The punch hammer is located in a fixed guide rail. The eight-connecting rod mechanical press of the utility model realizes diversified punch hammer pressure working curves, and solves the problems that conventional mechanism presses are poor in 'flexibility' and low in punch forming quality. In addition, the press of the utility model has excellent force transfer characteristic.
Description
Technical field
The utility model relates to the metal forming process equipment that does not have cutting, specifically, relates 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.The traditional mechanical forcing 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; Like 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 through the input of regulating servomotor, application is wider.
Summary of the invention
The purpose of the utility model is deficiencies such as metal forming is low with inefficiency, the Forming Quality that forcing press exists to having now, " flexibility " difference; The utility model 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.
The technical scheme of the utility model 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 through 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 through revolute pair with first crank, and second connecting rod is connected through revolute pair with second crank, and first connecting rod, second connecting rod, fork and block stamp connecting rod are connected through revolute pair in same point; Fork is connected with frame through revolute pair, and the end of block stamp connecting rod is connected with block stamp through revolute pair, and block stamp is within the fixed guide.
The beneficial effect of the utility model is: the present invention can obtain diversified block stamp pressure working curve, and it is poor to have solved traditional mechanical forcing press " 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 utility model specific embodiment.
The specific embodiment
The specific embodiment of the utility model 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 through 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 through revolute pair with first crank 2, and second connecting rod 5 is connected through 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 through revolute pair in same point; Fork 6 is connected with frame 1 through revolute pair, and the end of block stamp connecting rod 7 is connected with block stamp 8 through 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 receive 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.
