Abstract

PURPOSE:To smoothly pile up plate members without trouble by forming recessed grooves having curved lower surfaces on parts along the front edges of the plate members and the rear edges of opening parts and sliding the upper surface of the preceding plate member through this lower surface. CONSTITUTION:The plate stock is sent to a pressing part in sequence to make the plate members 1, 1' with the opening parts 1a, 1b, 1'a, 1'b, they are transferred one by one nearly horizontally and piled up mutually. In that case, on this pressed part, the recessed grooves 8, 9, 10 having curved lower surfaces are formed on the parts along the front edges 2 of the plate members 1, 1' and the rear edges 3, 4 of the opening part in advance. Further, the succeeding member 1' is slided to the rear edge 5 of the preceding plate member 1 and the front edges 6, 7 of the opening part so that its front edge 2 and the rear edges 3, 4 of the opening part are floated a little and through the curved lower surface of the recessed grooves 8-10. In this way, a catch or a thrust and a scratch are prevented from being generated and the plate members 1' are piled up smoothly and without trouble.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for pressing plate-shaped materials and stacking them one after another, and in particular, the present invention relates to a method for pressing plate-shaped materials and stacking them one after another. Please use the appropriate method.

[Conventional technology]

Conventionally, when pressing and stacking plate members constituting the body of an automobile, as shown in FIG.
Plate members 1, 1' with lb, 1'a, 1''b are made and are intended to be stacked on top of each other.

[Problem to be solved by the invention]

By the way, in the above-mentioned process, when the succeeding plate-like member 1' is slid and stacked on the preceding plate-like member 1, the front edge 2 and the opening rear edge 3 of the succeeding member 1' are .4 may get caught on the trailing edge 5 of the preceding member 1 or the front edge 6°7 of the opening, or may cause scratches on the surface of the preceding member 1, due to the respective machining edges and edges.

The present invention attempts to solve these problems, and aims to provide a method that allows pressed plate members with openings to be stacked without any problem.

[Means to solve the problem]

In order to achieve the above-mentioned object, the method of pressing and stacking plate-like members with openings according to the present invention is such that while sequentially feeding the plate-like materials to the press-working section, the plate-like members having openings are stacked in the press-working section. is produced, and when these plate-like members are transferred almost horizontally one by one and stacked on top of each other, in advance, in the press processing section, a curved lower surface is formed in a portion along the front edge of the plate-like member. In addition to forming a concave groove, a concave groove having a curved lower surface is formed in a portion along the rear edge of the opening, so that the trailing edge of the plate-like member that follows is It is characterized in that the plate member is slid through the curved lower surface of the groove so that its front edge and the rear edge of the opening are slightly raised.

[Function] In the above-described method for pressing and stacking plate members with openings according to the present invention, when creating a plate member with openings from a plate material in the press processing section, the press processing section is A groove having a curved lower surface is formed in a portion along the front edge of the plate member, and a groove having a curved lower surface is also formed in a portion along the rear edge of the opening of the plate member. Therefore, when a subsequent plate-like member is slid and stacked on top of a preceding plate-like member, the sliding action is smoothly performed via the curved lower surface of the groove.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of pressing and stacking plate-like members with openings as an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a plate-shaped member 1.1' with an opening made from a coiled plate-shaped material in a press working section. In the method of the present invention, as in the conventional case, the plate member 1.1' is not shown. A coiled plate-like material is fed into a press working section in a sequential manner, and the opening 1a is formed from the above-mentioned plate-like material in the press working section.

A plate-like member 1.1' having 1b, 1'a, and 1'b is produced and transported almost horizontally by a conveyor (not shown), etc., and at the stacking place, the plate-like member 1.1' is stacked with the preceding plate-like member 1. The subsequent plate-like member 1' is stacked on top.

By the way, in the method of the present invention, during the above-mentioned stacking,
In advance, at the press processing section, the front edge of each plate-like member 1.1' is punched at the same time as the peripheral edge and openings 1a, 1b, 1'a, 1'b of each plate-like member 1.1' are punched out. A concave groove 8 having a curved lower surface is formed by press working along a portion along the f of each opening 1aJb, 1'a, 1'b.
Concave grooves 9 and 10 that also have curved lower surfaces in the portions along &t&
After this, the subsequent plate member 1' is stacked on top of the preceding plate member 1.

That is, the following plate-like member 1' is placed so that its leading edge 2 and opening rear edges 3, 4 are slightly raised relative to the trailing edge 5 of the preceding plate-like member 1 and the front edges 6, 7 of the opening. A sliding action is performed via the curved lower surface of each groove 8, 9, 10. (See Fig. 2, 9) In this way, in the method of the present invention, the action of sliding and stacking the subsequent plate-like member 1' on the preceding plate-like member 1 is performed extremely smoothly, and the subsequent member The front edge 2 of the opening 1' and the rear edge 3.4 of the opening may get caught on the rear edge 5 of the preceding member 1 or the front edges 6, 7 of the opening, or may rub against the surface of the preceding member 1, due to the respective machining holes or edges. This prevents damage from occurring.

〔Effect of the invention〕

As described in detail above, according to the method of pressing and stacking plate-like members with openings of the present invention, a subsequent plate-like member with openings is placed on a previously pressed plate-like member with an opening f′t. The members can now slide and stack extremely smoothly, and the front edge of the subsequent plate-like member and the back of the opening have been removed from the rear edge and front edge of the opening of the preceding plate-like member with an opening, which had been a problem in the past. This has the effect of sufficiently preventing the edges from getting caught or stuck and the occurrence of scratches on the upper surface of the preceding member.
