RU1811424C - Extruded profile gripping mechanism - Google Patents

Abstract

Usage: in extrusion devices. Summary of the invention: the gripping mechanism comprises a detachable housing. A gear is installed in the casters in the casters. Parts of the housing may close and open together. Clamping elements are installed in the gear wheel. A guide pin is installed in the upper clamping element. In the initial position, the housing is open. The extruded profiles are fed to the lower clamping element. The housing closes and the profiles are clamped. As the housing moves, the gear rotates in the rollers and twists the profiles into a bundle. 2 ill.

Description

The invention relates to the processing of metals by pressure, in particular to the field of extrusion of profiles.

The aim of the invention is to increase the reliability of the extrusion profile gripping mechanism.

Figure 1 shows a structural diagram of the mechanism with an open grip; Fig. 2 is the same at the time of capture profile.

The extrusion profile gripping mechanism comprises a housing 1, a lower clamping element 2 and an upper clamping element 3 mounted therein, rotatably rotatable about an axis placed parallel to the longitudinal axis of the extrusion tool (the axis of rotation of the housing and the tool, as well as the tool itself, are not shown in the drawings ) The housing 1 is made detachable and its upper part is arranged to move in a plane perpendicular to the axis parallel to the longitudinal axis

extrusion tool, the mechanism is equipped with rollers 4-9 located in the housing 1, the drive rotates the clamping elements 2 and 3 at an angle greater than 360 ° in the form of a gear wheel 10, arranged to interact with the rollers 4-9 and made detachable to move into a plane perpendicular to the axis parallel to the longitudinal axis of the extrusion tool, a displacement drive of the upper part of the housing 1 (the displacement drive is not shown in the drawings) and a guide pin 11, rigidly fixed to the upper clamp mnom element 3.

The operation of the extrusion profile gripping mechanism is carried out as follows.

The gripping mechanism is brought to the press (the press is not shown in the drawings), while the upper part of the housing 1 is raised

that position (Fig. 1). The profiles 12 are fed into the housing 1 to the lower clamping element 2. The signal drives the movement of the upper part of the housing 1, which, turning on the shaft 13 clockwise, together with the rollers 4-6 installed in it, the upper part of the gear wheel 10, is rigidly the upper clamping element 3 fixed thereon and the guide pin 11 is lowered and lies on the lower part of the housing 1, while the guide pin 11 of the upper clamping element 3 abuts the lower clamping element 2 {or profile 12). The upper part of the gear 10 closes with its lower part, in a single unit, sends a signal to the drive of the clamping elements 2 and 3. The gear 10 starts to rotate in the rollers 4-9 in a plane perpendicular to the extrusion axis of the profiles 12. Profiles 12 located in the clamping elements 2 and 3, are twisted in one particular direction. The gear wheel 10 together with the profiles 12 completes three full revolutions (the number of revolutions is dictated by the receipt of a reliable connection of the profiles 12 to each other) and stops at the signal. The gripping mechanism with the profiles 12 clamped therein is withdrawn from the press. A signal is sent to the drive for moving the upper part of the housing 1, which, turning on the shaft 13 counterclockwise, rises up, thereby releasing the profiles 12 twisted from both sides into the bundle.

removal of profiles 12, and the gripping mechanism is brought to the press, the cycle of work is repeated.
