Problems solved by technology

Therefore, the number of linear motors for feeding the workpiece increases, the structure becomes complicated, and the manufacturing cost increases
[0020] As described above, even if the servo motor or other countermeasures are used, the effect of simplification of the structure is not sufficient, so there is a high demand for further simplification of the structure and cost reduction.

Embodiment approach 1

[0094] Embodiment 1 of the present invention will be described.

[0095] FIG. 1 shows a front view of a continuous automatic press machine (press machine) 1 according to Embodiment 1 of the present invention. FIG. 2 is a perspective view of a continuous automatic press machine (work transfer device) 41 .

[0096] First, the overall configuration of a continuous automatic press 1 according to Embodiment 1 of the present invention will be described with reference to FIG. 1 .

[0097] The continuous automatic press 1 is composed of a press main body 1A composed of a machine tool 23, a support column 21, a beam 20, and a slider 22, a mold 11 equipped with an upper mold 12 and a lower mold 13, a movable table 30, and a continuous automatic feeder 41 poses. In addition, a general-purpose robot 7 for unloading workpieces is provided on the downstream side of the continuous automatic press machine 1 .

[0098] A machine tool 23 serving as a pedestal for the continuous automatic pre...

Embodiment approach 2

[0146] Next, Embodiment 2 of the present invention will be described. In addition, the same reference numerals are used for the same parts as those described in Embodiment 1, and the description thereof will be omitted. The continuous automatic feeder 41A of Embodiment 2 uses one feeding linear motor 53A installed horizontally on the bar 14 to move the feeding movement of the plurality of feeding carriers 52 connected to each other. The continuous automatic feeder 41 of the mode 1 is different.

[0147] FIG. 13 shows a perspective view of a continuous automatic feeder 41A according to Embodiment 2 of the present invention. As shown in this FIG. 13 , in Embodiment 2, a moving member 58 is provided on the fixed rod 141 at one end of the rod 14 . The material direction can be guided freely. The feeding drive mechanism of the present invention is constituted by including the moving member 58, the linear guide 57, and the linear motor 53A for feeding.

[0148] Since there is a ...

Embodiment approach 3

[0157] Next, Embodiment 3 of the present invention will be described. In addition, the same code|symbol is used for the same part as what demonstrated in Embodiment 1 and Embodiment 2, and description is abbreviate|omitted. Embodiment 3 differs from Embodiment 1 in that the feed carrier 52 of Embodiment 1 is driven by a servo motor.

[0158] Figure 14 It is a perspective view which shows a part of continuous automatic feeder 41B of Embodiment 3. as it should Figure 14 As shown, the bar 14AA is the same as Embodiment 1, and a pair is provided parallel to the workpiece conveying direction, and a plurality of feeding carriers 52B are provided on a pair of feeding rails 51, 51 on the upper surface of the bar 14AA. Can be configured individually and moveably. and, Figure 14 Although one feed carrier 52B is shown in the figure, any number may be provided as needed.

[0159] The feeding carrier 52B is driven by a feeding servo motor (feeding drive mechanism) 58B provided on ...

Abstract

A work carrying device of a pressing machine, comprising a transfer feeder (41) having a lift / clamp device (80) moving a bar (14) in the lift direction and the clamp direction, a plurality of feed carriers (52) installed on the bar (14), and feeding linear motors (53) driving the feed carriers (52) in the feed direction. An object driven by the feeding linear motors (53) can be formed small in size since the feed carriers (52) are installed on the bar (14), the feeding linear motors (53) having a small capacity can be adopted to simplify the structure of a transfer press (1).

Description

technical field [0001] The invention relates to a work conveying device of a press machine. Background technique [0002] 27 shows a continuous automatic press 100 as a conventional press, four columnar support columns 121 are erected on a machine tool 123 located at the bottom of the press frame 110, and a beam 120 is provided on the support column 121. A slider driving device is built in the beam 120 to drive the slider 122 below the beam 120 up and down. In addition, an upper die 112 is attached below the slider 122 . A lower mold 113 is arranged on the upper surface of the movable workbench 130 facing the slider 122 , and the workpiece is punched and formed by the cooperation of the upper mold 112 and the lower mold 113 . A pair of left and right transfer rods 114 and 114 extend in parallel with the upper mold 112 and the lower mold 113 interposed therebetween. On a pair of transfer rods 114, 114, there are facingly provided with finger holders (fingers) for holding w...
