SU963628A1 - Device for centering guiding pins for removing products - Google Patents

Abstract

The mechanism for centring guide mandrels is used for removing the rotor and stator lamellac or electric machines from presses. On two parallel shafts which form a frame with transverse members are arranged two mirror image lifting arrangements. The latter move between stop of the transverse members and stop of the parallel shafts. The lifting elements have sliders and they are connected to drives. The sliders on the transverse members and lifting elements, can be adjusted. The adjustable sliders are arranged in pairs and they can be replaced.

Description

(54) DESIGN FOR CENTERING DIRECTION PINS FOR DIVIDING PRODUCTS

    one . . .

The invention relates to a device for automatically withdrawing articles from punch presses, in particular pioTopHHX sheets and stator packs j of electric machines.

Known methods and devices for removal of sheets of rotor and stator packages. For one of these devices, according to 117369, it was suggested that, after cutting, the products would slip down the guide pins penetrating into the press, assembled at the lower end of the guide pins into the stack, the height of which or the number of parts in which could be preselected were lowered after reaching the predetermined height of the stack or the number of parts in it on the stacking pins, JQ located under the guide pins, and then along with the stacking pins were moved away from the bed press. This retractor can be used in combination with both single and multiple cut dies. Guide pins penetrating Ugghp. at one end they are held and centered by means of sliders, which are placed on a fixed plate made in accordance with the product. On the slider plate, drive elements for pairs of sliders intended for a specific product are located.

The disadvantage of this design is that for each product it is necessary to make a new slider plate corresponding to it - and when re-adjusting the press to a new type of product, install it instead of the previous slider plate. This disadvantage leads to an increase in preparatory and final time and to a decrease in the utilization rate of the press.

The purpose of the invention is to improve this device, dp, centering, pushing and pulling, to minimize the cost of equipment designed for a particular product, and auxiliary time for switching to another type of product. .

Claims (6)

The goal is achieved by the fact that on two parallel axes, which, together with the transverse traverse arms and form a shape-like staiin, are placed two placed mirror-opposite one to another moving between the stops of the crossheads and the stops of the axes by means of the driving cylinders acting on them with sliders, forcibly connected through a mechanism, hinge but connected to the latter on both sides. The sliders are fixed on the transverse crossheads and on the crossheads with the possibility of shifting KHi. Replaceable resettable slider are placed in pairs, the sliders of each pair can be both the same and different in length and shape. The stops of the traverse and the stops of the axes are designed as resettable stops; In addition, the device can also be relocated within the press. The mechanism pivotally connected to the walking beam is a lever that is connected on both sides with the running arms and guide sleeves, and the guide pins of the guide sleeves are arranged symmetrically at right angles to the axles. In another embodiment of the mechanism design, it consists of two gear racks that are connected to one another and mounted on the axles. When changing to another type of product, the traverses with pairs of sliders, by means of the mechanism and the running cylinders, are forced to move to the stops in this manner It is indicated that the sliders lead out a guide pin intended for the product. from its centering position, and can thus be replaced with a guide pin corresponding to a new type of product. By swapping the sliders in the transverse and traverse traverse, an accurate adjustment of the pairs of sliders to the guide pin of the new product is carried out. In some cases, in particular when changing over from single-sided to multi-cutting die-cutting dies, it is required to use sliders of various lengths and shapes, which in this case are replaced only on the transverse and running traverses. After aligning the sliders, the running tracks are forced to move to the stops by means of the mechanism and the running cylinder so that the sliders accurately center the direction of the pin designed for the new type of product. Thus, using a single device, one can center the guide pins for rtbda products, and the working range of this device covers products of various sizes, shapes and positions. The invention is explained in more detail below in an exemplary embodiment. Fig. 1 shows a vertical half-cut of a press with an integrated centering device of the direction of & pins for removal of products; in Fig. 2, section A-A in Fig. 1, a variant of the lever mechanism; in Fig. 3, a section A-A in Fig. 1 (embodiment). The device for centering the guides for removing the products contains horizontally arranged guide columns 2 in the press 1, on which the traverse 3 is mounted with the possibility of adjusting movement, located symmetrically relative to the working positions of the press 1. On the columns 2 the traverse 4 is movably mounted, the hinge-connected with a lever mechanism 5, which can be made in the form of gears b and gear racks 7, fixed on traverse 4. In traverses 3 and 4 are installed with the possibility of adjusting movement relative to them, the sliders 8, which interact with the pins 9 located at the working position of the press 1, on which the products 10 are stacked, the flow from the tool is not shown) of the press 1. The pins 9 also serve to remove the stack of the product 10 from the working area of the press 1, Sliders 8 is made with the working part 11 directly interacting with the products 10. Columns 2 are equipped with adjustable displacements, stops 12 and 13. The device is installed in length 1 with adjustable displacements and is equipped with a moving mechanism 14 neither The cross member 4 is set in motion between the stops 12 and 13 of the power cylinders 15 mounted on the crosspiece 3. The mechanism 5 serves to synchronize the movement of the crosshead 4 and includes the direction of the sleeve 16 moving along the guide pins 17 arranged perpendicular to the guide columns. 2. Direction ((and columns 2 and traverse 3 form the device frame 18. Gears 6 and toothed rails 7 form mechanisms 19 for synchronizing the movement of traverse 4, When changing the position of the pins 9, it is necessary to install sliders 8 on traverse 3 and 4 to Claim 1. A device for centering guide pins for removal of products containing slides, guide pins for removal of a stack has been selected from 1 working area of the press, characterized in that it contains two parallel guide rails 2 on which they are installed. the stops 13 and the traverse 3 are fixed, forming together with the guide columns 2 the frame 18, and the bearing stops 12 mounted on the directional columns 2 with the ability to move relative to each other between the stops 12 and 13 from the power cylinders 15 tr The obverses 4, carrying the sliders 8 and interconnected by the movement synchronization mechanism, and the sliders 8 are fixed on the crossbars 3 and 4 with the possibility of adjusting movement. 2.
