Abstract
The invention relates to a servo press comprising a triangular swing rod. The press comprises a frame, a crank, a connecting rod, the triangular swing rod, a punch hammer connecting rod and a punch hammer, wherein the crank is connected with the frame through a revolute pair; the crank is connected with a servo motor and is driven by the servo motor to rotate; one end of a connecting rod is connected with the crank through the revolute pair; three joints of the triangular swing rod are respectively connected with the frame, the connecting rod and the punch hammer connecting rod 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. The stamping speed and the stamping position of the hammer can be accurately controlled by the servo motor, and due to the triangular swing rod, pressure working curves of the punch hammer can be diversified; and moreover, a complex motion output rule can be provided according to different press working processes, and the requirements of various stamping operations are 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, mechanical press is one of main equipments.The traditional mechanical forcing press adopts the fixed rotating speed motor as power source usually; 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, the mechanical press that servomotor directly drives 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 changes 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 does not use flywheel, and energy is all provided by servomotor during punching press; If when needing large tonnage pressing machine; Then will 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 existing metal forming is low with the production efficiency that forcing press exists, cost is high and above-mentioned deficiency such as " flexibility " difference; The present invention provides a kind of servo-pressing machine that contains the triangle fork; The motion under servomotor drives of this forcing press can realize the adjustment of block stamp position and speed, is 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 servo-pressing machine that contains the triangle fork, described forcing press comprise frame, crank, connecting rod, triangle fork, block stamp connecting rod and block stamp, and crank is connected through revolute pair with frame; Crank is connected with servomotor, and drives the crank rotation by servomotor; One end of connecting rod is connected through revolute pair with crank, and three nodes of triangle fork are connected with frame, connecting rod, 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 servomotor, can control the drawing velocity and the stamping position of block stamp accurately, and the adding of triangle fork, 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 servo-pressing machine that contains the triangle fork, described forcing press comprise frame 1, crank 2, connecting rod 3, triangle fork 4, block stamp connecting rod 5 and block stamp 6, crank 2 and frame 1 are connected through revolute pair; Crank 2 is connected with servomotor, and drives crank 2 rotations by servomotor; One end of connecting rod 3 and crank 2 are connected through revolute pair; Three nodes of triangle fork 4 are connected with frame 1, connecting rod 3, block stamp connecting rod 5 through revolute pair respectively; The end of block stamp connecting rod 5 is connected with block stamp 6 through revolute pair, and block stamp 6 is within the fixed guide.
During work, crank 2 rotates under the drive of servomotor, can realize the control of block stamp 6 positions and speed; In the effect of rotatablely moving of crank 2 down, connecting rod 3 is according to complex track setting in motion comparatively, and triangle fork 4 centers on frame 1 and does reciprocally swinging; Under the effect of triangle fork 4, block stamp connecting rod 5 is done complicated plane motion, in this process; Block stamp 6 also setting in motion under the effect of block stamp connecting rod 5; Because the horizontal direction that receives guide rail is spacing, and block stamp connecting rod 5 is hinged again with block stamp 6, so block stamp 6 can only punching press up and down in guide rail.
