Embodiment Construction
[0009] An edge-holding mechanism, which mainly includes a push rod 1, a guide sleeve 2, a connecting rod 3, a fixed seat 4, a single-acting cylinder 5, an air storage tank 6, and a compressed air source 7; its characteristic is: four identical connecting rods 3. The head and the tail are hinged to each other to form a parallelogram toggle mechanism. A hinge point at the upper end of the toggle mechanism is hinged to the ejector rod 1. The ejector rod 1 is installed on the guide sleeve 2. The ejector rod 1 has mutual sliding along the guide sleeve 2. Degree of freedom, the lowermost hinge point of the toggle mechanism and the fixed seat 4 are hinged together, and a single-acting cylinder 5 is symmetrically installed and fixed on the left and right sides of the toggle mechanism, and the piston of each single-acting cylinder 5 The rods are respectively hinged to the corresponding hinge points on the left and right sides, and the piston chambers of the two single-acting cylinders 5...

An edge pressing mechanism belongs to the technical field of mechanical presses. Four identical connecting rods are hinged to each other end to end to form a toggle link mechanism which is in the shape of a parallelogram. A hinged point at the upper end of the toggle link mechanism is hinged with an ejector rod, the ejector rod is mounted on a guide sleeve, a hinged point at the lowest end of the toggle link mechanism is hinged with a fixed seat, piston rods of single-acting cylinders which are symmetrically mounted on the left and the right of the toggle link mechanism are hinged with corresponding hinged points on the left and the right, piston cavities of the two cylinders are connected with an air storage barrel simultaneously, and the air storage barrel is connected with a compressed air source. The edge pressing mechanism is favorable for drawing operation and guaranteeing high product quality.
Description
technical field [0001] The invention relates to a mechanical press, in particular to an edge-holding mechanism of the mechanical press, and belongs to the technical field of the mechanical press. Background technique [0002] At present, at the bottom of the workbench of the mechanical press, a blank-holding mechanism is generally provided. The existing blank-holding mechanism is generally a single-acting cylinder. Although this kind of blank-holding mechanism has the advantage of simple structure, due to the During the process, as the compression space of the piston cylinder decreases, the air pressure in the piston cylinder also rises sharply, so this will lead to a sharp rise in the blank holder force, and in the stretching operation of the press, with the stretching depth The improvement of the blank holder requires the gradual reduction of the blank holder force to better ensure the quality of the product. Therefore, the existing blank holder mechanism is not conducive ...
