Abstract

The invention relates to an eight-rod servo pressing machine containing a triangular swinging rod, which comprises a machine frame, a first crank, a second crank, a first connecting rod, a second connecting rod, a triangular swinging rod, a punch hammer connecting rod and a punch hammer, wherein the first crank and the second crank are respectively connected to the machine frame through rotating pairs; the first crank is connected to a servo motor; the servo motor is used for driving the first crank to rotate; the first connecting rod is connected to the first crank through one rotating pair; the second connecting rod is connected to the second crank through one rotating pair; the first connecting rod, the second connecting rod and the triangular swinging rod are connected through one rotating pair at a same point; the triangular swinging rod is respectively connected to the machine frame and the punch hammer connecting rod through rotating pairs; the tail end of the punch hammer connecting rod is connected to the punch hammer through one rotating pair; and the punch hammer is arranged in a fixed guide rail. The eight-rod servo pressing machine containing the triangular swinging rod can be used for acquiring various pressing working curves of the punch hammer. The problems of the traditional mechanical pressing machine that the flexibility is inferior and the punch forming quality is low are solved. The addition of the triangular swinging rod is beneficial to further diversifying the pressing working curves of the punch hammer. Besides, the eight-rod servo pressing machine containing the triangular swinging rod has an excellent force-transferring property.

Description

The eight bar servo-pressing machines that contain the triangle fork
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 and punching machine are main equipments.Hydraulic press can be realized the large-tonnage stamping press, but inefficiency.Traditional punching machine 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, servo-pressing machine has appearred, as the wild company of day Home Network link lever press, Japanese Xiao Song HF series forcing press, Qiqihar second lathe group forcing press, this forcing press is driven by 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 bar servo-pressing machines that contain the triangle fork, 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 bar servo-pressing machines that contain the triangle fork, described forcing press comprises frame, first crank, second crank, first connecting rod, second connecting rod, triangle 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 and triangle fork are connected by revolute pair in same point; The triangle fork is connected with the block stamp connecting rod with frame by revolute pair respectively, 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; The adding of triangle fork can make the pressure working curve of block stamp more diversified; 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 bar servo-pressing machines that contain the triangle fork, 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 and triangle fork 6 are connected by revolute pair in same point; Triangle fork 6 is connected with block stamp connecting rod 7 with frame 1 by revolute pair respectively, 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, triangle 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.
