Abstract

PURPOSE:To move parallel a coil material from a driving guide mechanism up to an X-Y feeder and to prevent straining and flawing by providing the driving guide mechanism which moves transversely the coil material in synchronization with the transverse feed of the X-Y feeder in the inclined route for the coil material from a part for looping the coil material up to the X-Y feeder. CONSTITUTION:An X-Y feeder 10 feeds longitudinally and tansversely a coil material 1 at the same timing as a working timing of a press 12. A driving guide mechanism 8 and an auxiliary guide mechanism 15 move the material 1 in the tansverse direction in synchronization with the transverse feed thereof. The guide body of the mechanism 8 and the clamping parts 10a, 10b of the feeder 10 move transversely in parallel with the arc part 1b of the material 1 in-between and therefore generation of a twist in the arc part 1b is obviated and the arc part 1b is prevented from being strained and flawed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an improvement of a two-dimensional coil material feeding device that feeds a coil material having a width larger than a press die in the longitudinal direction (X-axis direction) and width direction (y-axis direction). It is related to.

In a conventional press primary processing line, the width of the coil material is determined according to the size of the product to be processed, and the wide coil material that has been rolled at the steel mill is slit and wound using a slitter. A coil material with the desired material width was made and then this coil material was punched out using a press.

but.

In order to slit a wide coil material to create a coil material with the desired material width, a slitter and winding device are required, so you have to rely on a company that has these equipment, which increases the material cost. there was. In addition, it was necessary to store several types of old coil materials with different widths.

In order to solve this problem, one of the inventors of the present invention developed an automatic coil material processing device that uses wide coil material that has been rolled in a steel mill as it is.
It has already been proposed in No. 39. That is, the coil material is also fed in the width direction, and the stress applied to the coil material thereby is released by a loop portion of a predetermined size formed between the continuous feeding device and the intermittent feeding device. In the process of actually commercializing this invention, several problems were found. One of them is that if an upper loop part 1a is formed in the coil material l as a loop part as shown in FIG. 1, will a gentle circular arc part lb be formed in front of the , When the coil material l is moved in the width direction by the xy feeder, twisting occurs in the circular arc portion 1b, which causes distortion in the coil material l, and also causes the guide member to rub strongly and become dirty. This also applies when the loop portion is down loose.

An object of the present invention is to provide a two-dimensional coil material feeding device that solves the above-mentioned problems and can prevent distortion and scratching at the arcuate portion immediately in front of the XY feeder.

To achieve this objective, the present invention provides an x
A drive guide mechanism is installed that moves the coil material in the width direction by an amount of movement equal to the amount of width direction feed by the xy feeder in synchronization with the feed in the width direction of the y feeder. The present invention is characterized in that a portion of the coil material including the circular arc portion 1b is moved in parallel.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

FIG. 2 shows a press working line using an embodiment of the present invention. The wound portion of the coil material 1 is rotatably supported by a coil holder 2. The unwound coil material l is straightened by a leveler 4 mounted on a pedestal 3, and at the same time is continuously fed. An upper loop portion 1a is formed after exiting the leveler 4. The size of the upper loop portion 1a is determined to be a predetermined size by the movable support 5a of the loop top guide device 5 expanding and contracting with respect to the fixed support 5b. A loop guide 6, which guides the tip of the coil material 1 when drawing a loop for the first time, can be placed on the frame 3.

The upper loop portion 1a releases the stress caused by the movement of the coil material 1 in the width direction and prevents the occurrence of distortion, so that the coil material 1 can be smoothly moved in the width direction.

The coil material 1 after the upper loop portion 1a follows an inclined path I
C, and reaches the horizontal route 1d while forming a circular arc part ib, or the inclined route 1c has a span plate 7 and a drive guide mechanism 8.
is provided. A roll kite 9 is provided in the arc portion 1b. The drive guide mechanism 8 moves the coil material l in the width direction by an amount of movement equal to the width direction feed amount by the xy feeder 10 in synchronization with the width direction feed of the xy feeder lO, but the details will be explained later. do.

An xy feeder 10 is provided on the horizontal path 1d. x

2 has a gate-shaped frame, and one or more sets of molds consisting of an upper mold 13 and a lower mold 14 are attached thereto. When a plurality of sets of molds are produced, the upper mold 13 is driven by its own drive source, for example, a hydraulic cylinder. An auxiliary guide mechanism 15 is installed on the exit side of the press 12. The auxiliary guide mechanism 15 holds the remaining material 16 coming out of the press 12 with a clamp member 15a, and in synchronization with the width direction feed of the xy feeder 10, removes the remaining material by an amount of movement equal to the amount of width direction feed by the xy feeder 10. 16 in the width direction. This improves the accuracy of movement of the coil material 1 in the width direction, so the area of the punched core portion becomes smaller, and efficient material utilization can be achieved.

Since the driving kite mechanism 8 and the auxiliary guide mechanism 15 operate in synchronization with the width direction feeding of the xy feeder 10, the drive source is derived from the motor 11 via the drive shaft 17, 18. In FIG. 2, the xy feeder lO1 drive 54 constitutes a two-dimensional coil material feeding device, but the auxiliary guide mechanism 15 may be omitted in the present invention.

Details of the drive guide mechanism 8 are shown in FIGS. 3 to 7.

In FIG. 3.4, a drive shaft 17 is rotatably supported on the support column 19, and a pulley 20 can be accessed from the drive shaft 17. The rotation of pulley 20 is transmitted to pulley 22 by timing bell I.21.

As shown in FIGS. 3 and 4, a guide body 33 is attached to the movable body 29. The details of the guide body 33 are shown in the seventh section.
As shown in the figure. FIG. 7 is a sectional view taken along the line A-A in FIG. 4 (excluding the coil material 1).

By fixing the bottom plate 34 to the movable body 29, the kite main body 33 can be removed from the movable body 29.

A plurality of lower guide rolls 36 are mounted on the bottom plate 34 by groove bearings 35, and a guide face plate 37 which is flush with the lower guide rolls 36 is provided. A pair of side guide rolls 38 are provided on both left and right sides of the bottom plate 34 by vertical shafts 39, and guide the coil material 1 by coming into contact with both left and right edges thereof. The position of the side guide roll 38 can be adjusted according to variations in the width of the coil phase 1. A holding member 40 that suppresses the springing up of the coil material 1 is attached to the shaft 39. An entrance guide 41 (FIG. 3) is provided in front of the guide body 33.

Next, the operation will be explained. The longitudinal direction feed, the width direction feed amount, and the timing thereof are determined in advance and stored in accordance with the type and dimensions of the punching process using the die. xy feeder 10 according to the timing of press processing
The coil material l is fed in the longitudinal direction and in the width direction,
In synchronization with the feed in the width direction, the drive guide mechanism 8 and the auxiliary guide mechanism 5 move the coil material I in the width direction.

To explain the operation of the driving kite mechanism 8 in detail, the motor 1
1 is transmitted through the drive shaft 17, the pulley 2
Pinion 24 by 0.22 and timing belt 21
is rotated to move the rack 32 in the width direction. Thereby, the movable body 29 and the guide body 33 move in the width direction of the coil material 1. On the other hand, the coil material l is
guided by the guide face plate 37 and the lower guide roll 36.
Although it passes over the guide face plate 37 and is guided to the roll guide 9, its movement in the left-right direction and upward is suppressed by the side guide rolls 38 and the presser member 40. Therefore, as the movable body 29 and the guide main body 33 move in the width direction, the coil material 1 is also moved in the width direction. This amount of movement is determined to be equal to the feed amount in the width direction of the xy feeder 10 depending on the gear ratio of the pinion 24 and the rack 32.

According to this embodiment, the guide main body 33 of the drive guide mechanism 8 and the clamp members 10a, 10b of the xy feeder 10 move in parallel in the width direction with the circular arc portion 1b of the coil material l sandwiched therebetween, so that one circular arc portion 1b does not twist, and the arc portion 1
Distortion and scratching at the upper loop portion 1a can be prevented, and stress caused by movement in the width direction can be concentrated on the upper loop portion 1a.

In the illustrated embodiment, the side kite roll 38 and the pressing member 40 are used in the drive guide mechanism 8, but a clamp member may be used instead of these. Although the auxiliary guide mechanism 15 is provided, it can be omitted if there is no need to reduce the core portion of the remaining material 16 so much.

The present invention is applicable not only to a press primary processing line having an amber loop portion 1a but also to a press 1 having a down loop portion.
It is also useful on the next processing line.

As explained above, the present invention provides a coil.

A drive guide mechanism that moves the coil material in the width direction along the inclined path of the coil material from the loop portion of the material to the xy feeder, in synchronization with the width direction feed of the xy feeder, by a movement amount equal to the width direction feed amount by the xy feeder. is installed, and the part of the coil material including the circular arc part just before the xy feeder of the xy tweeter machining is moved parallel from the drive guide mechanism, thereby preventing distortion and scratches in this circular arc part. be able to.
