Abstract
The utility model relates to a two-freedom-degree nine-rod mechanical press comprising a first crank, a second crank, a first connecting rod, a second connecting rod, a third connecting rod, a rack, an oscillating rod, a punching hammer connecting rod and a punching hammer. The first crank and the second crank are respectively connected with the rack by a rotation pair; the first crank and the second crank are connected with a motor with fixed rotation speed, and are driven to rotate by two motors with different rotation speed; the first connecting rod and the first crank are connected by the rotation pair, the second connecting rod is connected with the second crank by a rotation pair, and the first connecting rod, the second connecting rod and the third connecting rod are connected by rotation pairs at the same point; and the oscillating rod is connected with the rack by a rotation pair, the oscillating rod, the third connecting rod and the punching hammer connecting rod are connected with each other by rotation pairs at the same point, the tail end of the punching hammer connecting rod is connected with the punching hammer by a rotation pair, and the punching hammer is positioned in a fixed guide rail. According to the two-freedom-degree nine-rod mechanical press, the lower punching-forming speed, more varied pressure work curves of the punching hammer and the longer down time at a below dead point can be obtained, the problems of poor punching-forming quality of a traditional mechanical press and rebounding of a punching part and the like can be solved, and simultaneously, the press has a good force transmission property.
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, 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, 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 forcing press can improve the speed characteristics and the dynamic performance of slide block by the input of regulating servomotor, if when needing large tonnage pressing machine, then need to use powerful servomotor, but high-power servomotor price is very expensive, therefore the manufacturing cost height of this forcing press.
The utility model content
That the purpose of this utility model is is poor with the Forming Quality that forcing press exists at existing metal forming, suppress stamping parts resilience difficulty, " flexibility " difference and the high deficiency of cost, the utility model provides a kind of two degrees of freedom 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, more diversified block stamp pressure working curve and grow, satisfy the requirement of high-quality stamping press at bottom dead centre.
The technical solution of the utility model is: a kind of two degrees of freedom nine bar punching machines, described forcing press comprises first crank, second crank, first connecting rod, second connecting rod, third connecting rod, frame, fork, block stamp connecting rod and block stamp, and first crank is connected by 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 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 third connecting rod are connected by revolute pair in same point; Fork is connected by revolute pair with frame, and fork, third connecting rod and block stamp connecting rod are connected by revolute pair in same point, and the end of block stamp connecting rod is connected with block stamp by revolute pair, and block stamp is within the fixed guide.
The beneficial effects of the utility model are: can obtain lower punch forming speed, more diversified block stamp pressure working curve and in bottom dead centre long idle hours, it is of poor quality to have solved traditional punching machine punch forming, problems such as stamping parts resilience; 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
Specific embodiment of the utility model as shown in Figure 1, a kind of two degrees of freedom nine bar punching machines, described forcing press comprises that first crank 1, second crank 2, first connecting rod 3, second connecting rod 4, third connecting rod 5, frame 6, fork 7, block stamp connecting rod 8 and block stamp 9, the first cranks 1 and second crank 2 are connected by revolute pair with frame 6 respectively; First crank 1 and second crank 2 all respectively with decide the rotating speed motor and be connected, and different decide rotating speed driven by motor first crank 1 and 2 rotations of second crank by two respectively; First connecting rod 3 is connected by revolute pair with first crank 1, and second connecting rod 4 is connected by revolute pair with second crank 2, and first connecting rod 3, second connecting rod 4 and third connecting rod 5 are connected by revolute pair in same point; Fork 7 and frame 6 are connected by revolute pair, and fork 7, third connecting rod 5 and block stamp connecting rod 8 are connected by revolute pair in same point, and the end of block stamp connecting rod 8 is connected with block stamp 9 by revolute pair, and block stamp 9 is within the fixed guide.
During work, first crank 1 rotates under the rotating speed driven by motor two different deciding respectively with second crank 2, and first crank 1 drives first connecting rod 3 and does plane motion, and second crank 2 drives second connecting rod 4 and does plane motion; Under the acting in conjunction of first connecting rod 3 and second connecting rod 4, third connecting rod 5 is done plane motion; Under the effect of third connecting rod 5, fork 7 is done reciprocally swinging around frame 6, 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 be subjected to 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.
