Abstract
The utility model discloses a small high-thrust ejector. When the small high-thrust ejector is used for ejecting, pressure is transferred to a thruster through an ejector rod, and the thruster facing a conical block generates downward thrust and also generates pressure perpendicular to a wall surface of a cylinder, so that friction force is generated between the outer circumferential surface of the conical block and the inner wall of the cylinder, large upward thrust is applied to the ejector rod, and the friction force can be indirectly adjusted by means of adjusting the compression degree of a spring through an adjusting bolt. The ejector structurally has a small size, large return force can be generated, and the ejector is suitable for a narrow working space.
Description
Technical field
The utility model relates to a kind of forcing press ejector of metal forming machinery technology, and a kind of ejector of small-sized high thrust belongs to the metal forming machinery technology specifically.
Background technology
Ejector is the important accessory of metal forming machinery; Existing ejector mainly contains frame mode, and a kind of is to adopt elastomeric material as ejector; A kind of in addition is to adopt hydraulic cylinder as ejector; But all exist the thrust that produces less to some extent, the bigger shortcoming of volume of its structure own, the utmost point is limited by construction space.
The utility model content
In order to solve above-mentioned technological deficiency, the utility model provides a kind of small-sized affair ejector that pushes away greatly, not limited by construction space, and is easy to use.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: this utility model comprises ring flange, bolt, cylinder body, top pressing device, compression spring, circular cone, thruster, push rod, supporting plate, adjusting bolt, operating table surface.This utility model is provided with a cylinder body that is fixedly connected through push rod and operating table surface; A said push rod thruster and the top pressing device that correspondence is trapezoidal that is linked in sequence downwards; Both sides are respectively equipped with circular cone between said top pressing device and the thruster; The downward fixed order of said top pressing device is connected with compression spring and supporting plate; Said supporting plate is through regulating bolt on cylinder body, the surperficial corresponding coupling on the conical surface of thruster bottom and circular cone top wherein, and ring flange passes through the bolt stationary housing in the bottom of workbench.
The operation principle of the utility model is that when the work liftout, pressure is passed to thruster through push rod; Thruster produces downward thrust on the one hand in the face of circular cone, produces and the perpendicular pressure of cylinder body wall on the other hand, so; The periphery of circular cone just produces frictional force with the inwall of cylinder body, so, push rod is produced the bigger thrust that makes progress; Regulate the compression degree of bolt, the size that can regulate friction pulley indirectly to spring.
Beneficial effect: the utility model stripping attachment structurally has smaller volume, simultaneously, can produce bigger material returned strength, is suitable at less working space.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model;
Shown in the figure: 1, ring flange; 2, bolt; 3, cylinder body; 4, top pressing device; 5, compression spring; 6, circular cone; 7, thruster; 8, push rod; 9, supporting plate; 10, regulate bolt; 11, operating table surface.
The specific embodiment
In the drawings, this utility model comprises ring flange 1, bolt 2, cylinder body 3, top pressing device 4, compression spring 5, circular cone 6, thruster 7, push rod 8, supporting plate 9, regulates bolt 10, operating table surface 11.This utility model is provided with a cylinder body 3 that is fixedly connected through push rod 8 and operating table surface 11; Said push rod 8 thruster 7 and the top pressing device 4 that correspondence is trapezoidal that is linked in sequence downwards; Both sides are respectively equipped with circular cone 6 between said top pressing device 4 and the thruster 7; Said top pressing device 4 downward fixed order are connected with compression spring 5 and supporting plate 9; Said supporting plate 9 is fixed on the cylinder body 3 through regulating bolt 10, the surperficial corresponding coupling on the conical surface of thruster 7 bottoms and circular cone 6 tops wherein, and ring flange 1 passes through bolt 2 stationary housings 3 in the bottom of workbench 11.When the work liftout, pressure is passed to thruster 7 through push rod 8, and thruster 7 produces downward thrust on the one hand in the face of circular cone 6; Produce on the other hand and the perpendicular pressure of cylinder body 3 walls, so, the periphery of circular cone 6 just with the inwall generation frictional force of cylinder body 3; So; Push rod 8 is produced the bigger thrust that makes progress, regulate the compression degree of 10 pairs of springs of bolt, the size that can regulate friction pulley indirectly.
