Abstract
The invention relates to a nine-connecting-rod mechanical press, which comprises a first gear, a second gear, a first connecting rod, a second connecting rod, a three-pair component, a swinging rod, a frame, a punch hammer connecting rod and a punch hammer, wherein the first gear and the second gear are connected to the frame through rotating pairs; the first gear and the second gear are engaged with each other; the first connecting rod is connected to the first gear through one rotating pair; the second connecting rod is connected to the second gear through one rotating pair; the first connecting rod, the second connecting rod and the three-pair component are connected through one rotating pair at the same position; the three-pair component is respectively connected to the swinging rod and the punch hammer connecting rod through rotating pairs; the swinging rod is connected to the frame through one rotating pair; 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 nine-connecting-rod mechanical press can be used for acquiring a lower punch forming speed and a longer downtime at a lower dead point. The problems of the traditional mechanical press that the punch forming quality is inferior, a pressing piece bounds back, and the like, are solved. Meanwhile, the nine-connecting-rod mechanical press has an excellent force-transferring 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, mechanical press is one of main equipments.But traditional mechanical press can not effectively be controlled punch forming speed, is difficult to avoid the rebound phenomenon of stamping parts.In recent years, the servo-pressing machine that occurs, 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, though this forcing press can improve the speed characteristics and the dynamic performance of slide block, obtain multiple different pressure working curve, but manufacturing cost is higher.
Summary of the invention
The objective of the invention is to deficiencies such as metal forming is poor with the Forming Quality that forcing press exists at having now, inhibition stamping parts resilience difficulty, the invention provides a kind of nine connecting rod punching machines, this forcing press is by deciding the rotating speed driven by motor, the idle hours that can obtain lower punch forming speed and grow, satisfy the requirement of high-quality stamping press at bottom dead centre.
Technical scheme of the present invention is: a kind of nine connecting rod punching machines, described forcing press comprises first gear, second gear, first connecting rod, second connecting rod, three submembers, fork, frame, block stamp connecting rod and block stamp, first gear is connected with frame by revolute pair respectively with second gear, first gear and second gear are meshing with each other, first connecting rod is connected by revolute pair with first gear, second connecting rod is connected by revolute pair with second gear, first connecting rod, second connecting rod is connected by revolute pair at same place with three submembers, three submembers are connected with the block stamp connecting rod with fork by revolute pair respectively, fork is connected by revolute pair with frame, 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 lower punch forming speed and in bottom dead centre long idle hours, and 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 specific embodiment of the invention.
The specific embodiment
Specific embodiments of the invention as shown in Figure 1, a kind of nine connecting rod punching machines, described forcing press comprises first gear 1, second gear 2, first connecting rod 3, second connecting rod 4, three submembers 5, fork 7, frame 6, block stamp connecting rod 8 and block stamp 9, first gear 1 is connected with frame 6 by revolute pair respectively with second gear 2, first gear 1 and second gear 2 are meshing with each other, first connecting rod 3 is connected by revolute pair with first gear 1, second connecting rod 4 is connected by revolute pair with second gear 2, first connecting rod 3, second connecting rod 4 is connected by revolute pair at same place with three submembers 5, three submembers 5 are connected with block stamp connecting rod 8 with fork 7 by revolute pair respectively, fork 7 and frame 6 are connected by revolute pair, 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 gear 1 rotates under the drive of constant-seed motor, under the drive of first gear 1, second gear 2 rotates, under the effect of first gear 1 and second gear 2, first connecting rod 3, second connecting rod 4 and three submembers 5 are done complicated plane motion respectively, fork 7 is done reciprocally swinging around frame 6, block stamp connecting rod 8 is done plane motion, in this process, block stamp 9 also setting in motion under the effect of block stamp connecting rod 8 is 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.
