Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a material supply system for simultaneous processing of multiple products, which simultaneously supplies different types of blanks to a transfer press capable of simultaneously processing different types of products.

[Conventional technology]

Conventionally, in transfer presses, in order to press different types of blanks, such as blanks for left-right symmetrical products, the left-right symmetrical products were processed alternately in stages, for example, a mold for the left product was placed at each processing stage of the transfer press. are installed in a row and the left blank is supplied to this to complete the left product, while a mold for the right product is installed in a row and the right blank is supplied to this to complete the right product, or the right product is completed at each processing stage. Simultaneous machining molds for left-right symmetrical products were installed in a row, and left-right symmetrical products were simultaneously processed from a single blank, separated in the final process to complete the left and right products.

In addition, when supplying blanks, there are cases in which a blanking stage for processing blanks from coil material is provided, cases in which a stack feeder loaded with blanks is provided, and cases in which these are installed together with compatibility. However, all of them were installed on one side of the transfer press and supplied one blank to each processing stage in sequence.

[Problem that the invention attempts to solve]

The above-mentioned conventional material feeding device sequentially feeds blanks one by one, and since the number of processing stages varies depending on the product, there is play in the processing stages, resulting in a lack of versatility.

In particular, when machining symmetrical products, it takes a lot of man-hours to reinstall all the molds installed in a row in order to supply the left or right blank and complete the left or right product, which reduces the operating rate of the press. There are drawbacks that reduce it. In addition, in simultaneous processing of left-right symmetrical products, although there is an advantage of simultaneous processing, deformation may occur due to differences in material retraction during forming of left-right symmetrical products, and material yield may be large depending on the blank shape. There were various drawbacks, such as a drop in production capacity and the need for separate molds to separate the left and right products in the final process.

The purpose of the present invention is to eliminate these drawbacks, make effective use of each processing stage of the transfer press without play, and eliminate the above-mentioned drawbacks of the conventional transfer press even when processing symmetrical products. Our goal is to provide a material supply system for simultaneous product processing.

[Means for solving problems]

The configuration of the present invention is a material supply system for simultaneous processing of multiple products in a transfer press that supplies materials to a transfer press having multiple processing stages. a disk feeder capable of feeding the first processing stage of the press; and a disk feeder provided at the front face of the transfer press so as to be movable in a direction parallel to the front face of the press and across a plurality of processing stages. It is characterized by comprising a truck and a coil line provided on the truck to supply coil material to any processing stage of the press.

[Effect]

If blanks from the stack feeder can be processed in only a part of the processing stages of the transfer press, by supplying coil material from the coil line to the remaining processing stages, the processing stages can be utilized without play.

In addition, since multiple blanks can be fed at the same time using the stack feeder, symmetrical products can be processed at the same time. In this case, since a left-right symmetrical product is not simultaneously processed from a single blank, there is no deformation due to differences in material retraction, and the blank can be manufactured separately with a high yield, saving on materials. Since there is no need to separate the products, separate molds are not required and mold costs can be reduced. In addition, since symmetrical products can be processed at the same time, it is possible to prevent a drop in operating efficiency due to mold installation changes.

〔Example〕

FIG. 1 shows a transfer press 1 equipped with the material supply system of the present invention. A stack feeder 2 is installed on the side of the transfer press 1 and can be used to selectively feed two different types of blanks at the same time or one blank.
has been established. In addition, a set of rails 3 are laid on the floor at the front of the transfer press 1 in parallel to the front of the press and in the left-right direction across multiple processing stages of the press 1. A movable trolley 4 is provided. Coil material 5 is placed on the trolley 4.
A coil line 8 is provided, which is composed of an uncoiler 6 which is loaded and fed out, and a leveler feeder 7 which corrects the bending etc. of the coil material 5 fed out from the uncoiler 6 and intermittently supplies it to the transfer press 1. By moving the cart 4 left and right and stopping it, the coil material 5 supplied from the leveler feeder 7 can be made to correspond to any mold in each processing stage of the transfer press 1.

At the rear of the transfer press 1, there is a unit 1 for carrying out the moving bolster 9 from the transfer press 1.
This moving bolster is provided with a set of rails 10 and a set of rails 11 for running the transported moving bolster 9 in a direction perpendicular to the rails 10, that is, in the left-right direction of the transfer press 1, and in which molds are arranged in rows at each processing stage. By replacing 9, the mold can be replaced in a short time. Each processing stage on the moving bolster 9 is equipped with two molds (not shown) when processing symmetrical products at the same time, and one mold each when processing one product. A mold (not shown) is provided.

The blanks supplied from the stack feeder 2 and the blanks (not shown) supplied with the coil material 5 and produced in the processing stage are sequentially processed at a constant pitch by a pair of feed bars 12 of the transfer press 1. The material is transported, supplied from mold to mold at each processing stage, pressed, and taken out as a product (not shown).

[Effect of idea]

As is clear from the above description, the present invention has the following effects.

Since a transfer feeder and a movable coil line are provided corresponding to each processing stage of the transfer press, each processing stage of the transfer press can be used without play.

Since the stack feeder can feed multiple blanks at the same time, it is possible to process symmetrical products at the same time. Therefore, it is not necessary to process left-right symmetrical products separately, so it is possible to prevent a decrease in the operating rate of the press.

In this case, since a left-right symmetrical product is not processed simultaneously from a single blank, there is no deformation due to differences in material retraction, and the blank can be manufactured separately with a high yield, saving on materials. Since the product is not separated, separate molds are not required and mold costs can be reduced.

Since coil material can be supplied from any of the processing stages of the press, it can be used in conjunction with a disk feeder to provide optimal support for processing a variety of products.
