落料模自动送料装置

Abstract

本实用新型公开了一种落料模自动送料装置，安装于压力机上，用于向落料模输送线材，包括送料结构和位于送料结构上方的触发结构；本实用新型的重点在于：送料结构包括安装座、夹持组件以及固定于安装座上的气缸和气阀，夹持组件与落料模的进料口对应且滑动连接于安装座的两导轨上，气缸位于夹持组件的后方且其伸缩杆与夹持组件连接，气阀与气缸连通；触发结构包括固定座以及与气阀对应的打杆，打杆在上模的带动下上下运动以使其松开或者按压气阀的开关，使得打杆通过气阀来控制伸缩杆向前推动或者向后复位夹持组件，从而能在冲压的间隙实现自动送料，可不需要安装机器人或者机械手，不但结构简单且成本低。

Claims

1. An automatic feeding device for a blanking die, which is installed on a press and is used to feed a wire rod to a blanking die, characterized in that, It includes a feeding structure and a triggering structure located above the feeding structure; The feeding structure is connected to the worktable of the press and includes a mounting base, a clamping assembly for feeding the wire, and a cylinder and a valve fixed on the mounting base. The mounting base is fixed to the worktable and is fixedly connected to two guide rails located above the worktable. The clamping assembly is slidably connected to the two guide rails. The cylinder is located behind the clamping assembly and its telescopic rod is connected to the clamping assembly. The valve is located on one side of the guide rail and communicates with the cylinder. The triggering structure includes a fixed base fixed to the rear side of the upper die of the blanking die, and a striking rod connected to the fixed base and corresponding to the air valve. The striking rod moves up and down under the drive of the upper die to release or press the switch of the air valve, so that the striking rod controls the telescopic rod to push forward or reset the clamping assembly through the air valve.

2. The blank die automatic feeding apparatus according to claim 1, wherein The fixed base extends rearward and a connecting base is fixedly connected to its rear end. The striking rod is fixedly connected to the connecting base and its lower end extends downward to below the connecting base. When the striking rod moves downward under the drive of the upper mold, the switch can be pressed. When the striking rod moves upward under the drive of the upper mold, the switch can be released.

3. The automatic feeding device for the blanking die as described in claim 2, characterized in that, The rear end of the fixed base has a through hole extending vertically through it. The through hole extends in the front-to-back direction and has a bolt inside it. The top surface of the connecting base near the fixed base has a slot corresponding to the through hole. The slot extends through the connecting base from front to back and engages with the rear end of the fixed base. The bottom surface of the slot has a connecting hole corresponding to the through hole and downwards, which engages with the bolt.

4. The blank die automatic feed apparatus of claim 2 wherein, The connector extends toward and above the switch. The connector has a threaded hole extending through it from top to bottom at one end near the switch. The lever is threadedly connected to the threaded hole and the two are locked together by a nut.

5. The blank die automatic feed apparatus of claim 1 wherein, The fixing seat is fixed to the rear side wall of the upper mold, and the left and right outer side walls at its front end respectively protrude to form a positioning part. Each positioning part has a positioning hole that runs through it from front to back. Each positioning hole extends in the left and right direction and has a bolt for connecting the upper mold and the positioning part inside it.

6. The blank die automatic feed apparatus of claim 1 wherein, A lower bracket located on the right side of the clamping assembly is fixed to the right side wall of the mounting base, and the air valve is fixed to the lower bracket.

7. The blank die automatic feed apparatus of claim 6 wherein, The lower support extends forward, and the front end of the air valve protrudes forward relative to the front end of the lower support. The front end of the air valve is rotatably connected to a switch. The lever can abut against the switch to press the switch downward, causing the switch to rotate downward. When the lever releases the switch upward, the switch disengages from the lever and resets.

8. The automatic feeding device for blanking mold as described in claim 1, characterized in that, The device includes a slide fixed to the worktable. The left and right ends of the rear sidewall of the slide are respectively recessed to form a sliding groove extending in the vertical direction. The left and right ends of the front end face of the mounting base are respectively fixed with a slider. One slider slides in cooperation with one of the sliding grooves. The slider and the slide are locked by bolts. The cylinder is located between the two guide rails and below the clamping assembly.

9. The blank die automatic feed apparatus of claim 8 wherein, Each slider has a rear locking hole extending downwards to the bottom of the mounting base. The rear locking hole extends vertically. The bottom surface of the slide groove has a front locking hole corresponding to each rear locking hole. The bolt is provided in the rear locking hole and passes forward through the rear locking hole and engages with the front locking hole.
