Abstract
The invention relates to a novel nine-rod mechanical press. The press comprises a frame, a first crank, a second crank, a first connecting rod, a second connecting rod, a ternary link, 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 through a revolute pair, are connected with fixed rotating speed motors and are respectively driven by two different fixed rotating speed motors to rotate; the first connecting rod is connected with the first crank through the revolute pair; the second connecting rod is connected with the second crank through the revolute pair; the first connecting rod, the second connecting rod and the ternary link are connected at the same part through the revolute pair; the swing rod is connected with the frame through the revolute pair and is connected with the ternary link through the revolute pair; the punch hammer connecting rod is connected with the ternary link through the revolute pair; the tail end of the punch hammer connecting rod is connected with the punch hammer through the revolute pair; and the punch hammer is positioned in a fixed guide rail. By the novel nine-rod mechanical press, a relatively low press forming speed and a long down time at a lower dead point can be guaranteed, and the problems that the traditional mechanical press has a poor press forming quality, a stamped part deforms and the like are solved; and moreover, due to the ternary link, pressure working curves of the punch hammer can be diversified, and the press has excellent force transmission characteristics.
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, punching machine is one of main equipments.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 modern market product diversification, changes fast, little requirement in batches.In recent years; Servo-pressing machine 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 forcing press can improve the speed characteristics and the dynamic performance of slide block through the input of regulating servomotor, but the manufacturing cost of this forcing press is high.
Summary of the invention
The objective of the invention is to poor to existing metal forming with the Forming Quality that forcing press exists, suppress stamping parts resilience difficulty, " flexibility " difference and the high deficiency of cost; The present invention provides a kind of novel nine bar punching machines; This forcing press is decided the rotating speed driven by motor by two; The idle hours that can obtain lower punch forming speed, diversified block stamp pressure working curve and grow, satisfy the requirement of high-quality stamping press at bottom dead centre.
Technical scheme of the present invention is: a kind of novel nine bar punching machines; Described forcing press comprises frame, first crank, second crank, first connecting rod, second connecting rod, three submembers, fork, block stamp connecting rod and block stamp, and first crank is connected through revolute pair with frame respectively with second crank; First crank and second crank all with decide the rotating speed motor and be connected, and different decide rotating speed driven by motor first crank and the rotation of second crank by two respectively; 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 and three submembers are connected through revolute pair in same point; Fork is connected through revolute pair with frame, and fork is connected through revolute pair with three submembers; The block stamp connecting rod is connected through revolute pair with three submembers, and the end of block stamp connecting rod is connected with block stamp through revolute pair, and block stamp is within the fixed guide.
Beneficial effect of the present invention is: the present invention can obtain lower punch forming speed and in bottom dead centre long idle hours, and it is of poor quality to have solved the punch forming of traditional mechanical forcing press, problems such as stamping parts resilience; And the adding of three submembers, also 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 embodiment of the present invention as shown in Figure 1; A kind of novel nine bar punching machines; Described forcing press comprises that frame 1, first crank 2, second crank 4, first connecting rod 3, second connecting rod 5, three submembers 6, fork 7, block stamp connecting rod 8 and block stamp 9, the first cranks 2 and second crank 4 are connected through revolute pair with frame 1 respectively; First crank 2 and second crank 4 all with decide the rotating speed motor and be connected, and different decide rotating speed driven by motor first crank 2 and 4 rotations of second crank by two respectively; 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 are connected through revolute pair in same point with three submembers 6; Fork 7 and frame 1 are connected through revolute pair, and fork 7 is connected through revolute pair with three submembers 6; Block stamp connecting rod 8 is connected through revolute pair with three submembers 6, and the end of block stamp connecting rod 8 is connected with block stamp 9 through revolute pair, and block stamp 9 is within the fixed guide.
During work, first crank 2 rotates under the rotating speed driven by motor two different deciding respectively with second crank 4, and first crank 2 drives first connecting rod 3 and does plane motion, and second crank 4 drives second connecting rod 5 and does plane motion; Under the acting in conjunction of first connecting rod 3 and second connecting rod 5, three submembers 6 are done plane motion; Under the effect of three submembers 6, fork 7 is done reciprocally swinging around frame 1, and block stamp connecting rod 8 is done complicated plane motion; In this process, block stamp 9 also setting in motion under the effect of block stamp connecting rod 8, because it is spacing to receive the horizontal direction of guide rail, and block stamp connecting rod 8 is hinged again with block stamp 9, so block stamp 9 can only punching press up and down in guide rail.
