Description

Mechanical CNC press

technical field

The invention relates to metal forming processing equipment, in particular to a new type of mechanical press which adopts numerical control method for processing operation.

Background technique

In the field of metal forming processing, especially in the sheet metal stamping, forming, and sheet drawing processes, the use of mechanical crank presses for stamping processing has become one of the most important processing technologies in the production and manufacture of mechanical and electrical products. However, traditional mechanical presses usually use a fixed-speed motor as the power source. Through various transmission devices, the actuator works with a fixed pressure curve, and the pressure work curve required by the user according to different processing techniques cannot be obtained. The inherent defect of the lack of "flexibility" of this kind of press hinders the further improvement of the stamping process level, so it is difficult to meet the requirements of modern market product diversification, rapid change, and small batches.

Contents of the invention

The purpose of the present invention is to provide a novel method for grinding spur gears using a spline shaft grinder to address the shortcomings of the existing production process of grinding spur gears by transforming a spline shaft grinder

The technical solution of the present invention is: a mechanical numerical control press, the press includes a servo motor, a slider in the slide rail, three secondary components, and a hammer, the servo motor and the slider The three pairs of components are connected by ball screw pairs. The three nodes of the three pairs of components are respectively hinged with the slider, a connecting rod fixed at one end, and the hammer connecting rod. The end of the hammer connecting rod is connected to the hammer, and the hammer is located between the guide rail Inside.

Preferably, two three-pair components are symmetrically arranged on the slider, and among the three nodes of the two three-pair components, one of them is jointly hinged on a slider, and the other two nodes Each is connected with a connecting rod fixed at one end and a hammer connecting rod to form two sets of stamping mechanisms controlled by servo motors.

The beneficial effect of the present invention is that the punching speed and punching position of the punching hammer can be precisely controlled by using the cooperation of the servo motor and the ball screw, and the addition of three sub-components can also make the pressure working curve of the punching hammer more diversified At the same time, the structure of the press is simple and compact, and the cost is low. As long as an appropriate die is installed on the press, processes such as punching, blanking, bending, forming, drawing and fine pressing can be completed.

Detailed ways

The first specific embodiment of the present invention shown in Figure 1 is a mechanical numerical control press, which includes a servo motor 1, a slider 3 in a slide rail, three secondary components 4, and a punch The hammer 7, the servo motor 1 and the slider 3 are connected through the ball screw pair 2, and the three nodes of the three secondary components 4 are respectively connected to the slider 3, a connecting rod 5 fixed at one end, and a hammer connecting rod The 6 phases are hinged, the end of the hammer connecting rod 6 is connected to the hammer 7, and the hammer 7 is in the guide rail.

When working, the ball screw pair 2 is used to convert the rotary motion of the servo motor 1 into a linear motion, thereby driving the slider 3 to start moving in the vertical direction, and the nodes hinged with the slider 3 in the three secondary components 4 also start to move up and down Vertical movement, and the node hinged with the connecting rod 5, under the action of the fixed point 8, starts to make a circular motion with the fixed point 8 as the center and the connecting rod 5 as the radius, while the node hinged with the hammer connecting rod 6 Then it starts to move according to a more complicated trajectory. During this process, the hammer also starts to move under the action of the hammer connecting rod 6. Because it is limited by the horizontal direction of the guide rail, and the hammer connecting rod 6 and the hammer 7 are in contact with each other. Hinged to each other, so the hammer 7 can only punch up and down in the guide rail.

The first specific embodiment of the present invention shown in Figure 2, in this specific embodiment, two sets of three sub-components 4 are connected on the slider 3, and the three sub-components 4 are respectively connected with a hammer 7, so that Then, two sets of stamping mechanisms are formed in one plane.

Based on the above embodiment, if the slider 3 is large enough, more sets of three sub-components can be connected to the slider, and the same structure can be used to make the punching machine more widely used.
