Embodiment Construction

[0014] A kind of moldless and riveted connection equipment of the present invention is realized like this:

[0015] A dieless riveted connection device is composed of a drive motor (1), a punch system (2), a flat anvil (3) and a C-shaped frame (4), wherein the punch system (2) consists of a punch sleeve (5 ), a stepped punch (6), a pressure regulator (7), a spring (8), a blank holder (9) and a positioning pin (10), the lower end of the drive motor (1) is connected to the punch system (2), The punch system (2) can move up and down as a whole driven by the driving motor (1). In the punch system (2), the spring (8) is located between the pressure regulator (7) and the blank holder (9), and the pressure regulator (7) and the punch sleeve (5) are connected through threads, which can be passed Rotate the pressure regulator (7) to adjust its up and down position, so as to adjust the spring force of the initial state and play the role of adjusting the initial pressure of the blank ho...

Abstract

The invention provides a mold-free and rivet-free connection device, relating to the field of machinery manufacturing. The whole device comprises a drive motor (1), a punch system (2), a flat anvil platform (3) and a C-shaped framework (4), wherein the punch system (2) comprises a punch sleeve (5), a ladder-type punch (6), a pressure regulator (7), a spring (8), an edge pressing ring (9) and a positioning bolt (10), the lower end of the drive motor (1) is connected with the punch system (2), and the punch system (2) can move vertically as a whole. The spring (8) is arranged between the pressure regulator (7) and the edge pressing ring (9), the pressure regulator (7) is connected with the punch sleeve (5) through threads, and the vertical position of the pressure regulator (7) can be changed to achieve the function of adjusting the pressure of the edge pressing ring. The invention has the advantages of simple structure and low manufacturing cost, and the rivet-free connection can be well realized.

Description

Technical field: [0001] The invention relates to the field of mechanical manufacturing, in particular to a non-rivet connection device in a moldless form. Background technique: [0002] At present, lightweight has become a trend in the development of the automobile industry. Lightweight has prompted the use of a large number of lightweight materials, such as aluminum alloys, magnesium alloys, and plastics. Because the physical and chemical properties of these lightweight materials are not suitable for traditional connection methods, such as spot welding, many new connection methods have been spawned. These new connection methods are mainly used in mechanical connection methods, such as semi-hollow rivet self-piercing riveting and rivetless connection, which can avoid many defects caused by spot welding. [0003] Rivetless connection is a connection method in which a punch is pressed into the connected plates to cause plastic deformation of the plates and a mechanical interl...
