Abstract
The invention relates to a toggle rod-type servo pressing machine which comprises a servomotor, a ball screw, a sliding block, a connecting rod, a triangular swing stem, a machine frame, a punch hammer connecting rod and a punch hammer, wherein the servomotor and the sliding block are connected through a ball screw assembly; one end of the connecting rod and the sliding block are connected through a revolute pair; three nodes of the triangular swing stem are respectively connected with the connecting rod, the machine frame and the punch hammer connecting rod through the revolute pairs; the tail end of the punch hammer connecting rod is connected with the punch hammer through each revolute pair; and the punch hammer is positioned in a fixed guide rail. According to the matching of the servomotor and the ball screw, the punching speed and the punching position of the punch hammer can be controlled accurately; in addition, the triangular swing stem is additionally arranged, so that the pressure working curve of the punch hammer can also be diversified, and various requirements of the punching operation can be met.
Description
Technical field
The present invention relates to not have the metal forming process equipment of cutting, specifically, relate to a kind of servo-pressing machine.
Background technology
At the metal forming manufacture field; Particularly in sheet-metal press working, moulding, thin plate drawing process; The traditional mechanical forcing press is owing to adopt the fixed rotating speed motor as power source; Make executing agency carry out work with the fixed pressure curve; Can not obtain the pressure working curve of user, thereby this forcing press inherent shortcoming that lacks " flexibility " hindered the further raising of Sheet Metal Forming Technology level, be difficult to satisfy the modern market product diversification, change fast, little requirement in batches according to different processing technology needs.In recent years; The mechanical press that servomotor directly drives occurred, like the wild company of day Home Network link lever press, Japanese Xiao Song HF series 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, this forcing press is not owing to use flywheel, and energy is all provided by servomotor during punching press; If when needing large tonnage pressing machine; Then need use powerful servomotor, but high-power servomotor price is very expensive, therefore the manufacturing cost of this forcing press is very high.
Summary of the invention
The objective of the invention is to the deficiencies such as " flexibility " difference of existing metal forming with the forcing press existence; The present invention provides a kind of toggle rod type servo-pressing machine; This forcing press is driven by servomotor, can realize the adjustment of block stamp position and speed, and this forcing press can be according to different pressure processing crafts; The complicated motion output rule is provided, satisfies the requirement of various stamping press.
Technical scheme of the present invention is: a kind of toggle rod type servo-pressing machine; Described forcing press comprises servomotor, ball-screw, slide block, connecting rod, three secondary forks, frame, block stamp connecting rod and block stamp; Be connected through ball screw assembly, between described servomotor and the slide block; One end of connecting rod is connected through revolute pair with slide block; Three nodes of three secondary forks are connected with connecting rod, frame, block stamp connecting rod through revolute pair respectively, 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 utilizes cooperating of servomotor and ball-screw, can control the drawing velocity and the stamping position of block stamp accurately, and the adding of three secondary forks, also can make the pressure working curve of block stamp more diversified; Simultaneously, forcing press simple and compact for structure, cost is low, as long as suitable punch die is installed, just can accomplish stamping-out, blanking, bending, moulding on forcing press, draw and technology such as pressure-sizing.
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 toggle rod type servo-pressing machine; Described forcing press comprises the secondary fork of servomotor 1, ball-screw 2, slide block 3, connecting rod 4, three 6, frame 5, block stamp connecting rod 7 and block stamp 8; Be connected through ball screw assembly, 2 between described servomotor 1 and the slide block 3, an end of connecting rod 4 and slide block 3 are connected through revolute pair, and three nodes of three secondary forks 6 are connected with connecting rod 4, frame 5, block stamp connecting rod 7 through revolute pair respectively; 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, utilize ball screw assembly, 2 to convert rotatablely moving of servomotor 1 into rectilinear motion, thereby drive the motion of slide block 3 beginning vertical direction; Connecting rod 4 is done complicated plane motion, and triangle fork 6 is done reciprocally swinging around frame 5, under the effect of triangle fork 6; 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 is 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.
