Description

A New Grabbing Device Applied in Thin-wall Umbrella Rib Rotary Cutting Machine

technical field

The utility model belongs to the field of mechanical parts for processing umbrella ribs, and relates to a novel material grabbing device used in a thin-wall umbrella rib rotary cutting machine.

Background technique

At present, the cutting of thin-walled steel pipes in China mainly uses manual methods for single cutting. The steel pipe is fixed and clamped. Since the blade can only be fed slowly, there will be problems such as slow speed, low work efficiency, and the inability to guarantee the roundness of the steel pipe. , and there are also defects such as burrs in the cut, poor product quality, and high labor intensity for operators.

If the method of rotating the steel pipe to cut is adopted, then manual feeding will be very dangerous, and the operator cannot wear gloves. In addition, in order to keep the thin-walled tube from deforming during cutting, it must be rotated. Due to the increase in the diameter of the steel pipe and the relative increase in the length of the steel pipe, the steel pipe with a length of more than 6 meters needs to be cut into pipe fittings ranging from 2 to 3 meters and then fine-cut according to the required size. This method of not requiring quantity but only quality has also become a technical problem, and measures to overcome safe production are one of the keys to technological improvement. The domestic umbrella industry and many other processing industries need a large number of processed thin-walled steel pipes, so the market potential is huge.

Contents of the invention

In order to make up for the above-mentioned shortcomings of slow speed, low work efficiency, inability to ensure the roundness of the steel pipe, burrs in the cut, poor product quality, and high labor intensity of the operator, the utility model provides a kind of rotary tube for thin-walled umbrella ribs. The new grabbing device in the cutting machine is one of the important components of the thin-wall umbrella rib rotary cutting machine. It has the characteristics of low processing cost, high work efficiency, high production safety performance, stable product quality, and no burrs in the cut.

In order to achieve the above purpose, the utility model adopts the following specific technical solutions: a new material grabbing device applied to the thin-walled umbrella rib rotary cutting machine, which is composed of a material grabbing cylinder, a push rod, a conduit, a C-shaped movable claw, an I The structure is characterized by a built-in push rod in the conduit, a sleeve of the C-shaped movable claw is set on the conduit, the bolt is fastened to the C-shaped movable claw through the chute of the conduit, and the I-shaped fixed claw It is fixed on the conduit, and the catch cylinder is connected with the push rod;

Wherein, the ejecting rack is composed of a cross bar, a U-shaped support groove, a guide seat, and an ejecting cylinder. The ejecting rack is correspondingly parallel to the guide tube. A plurality of guide seats and a plurality of groups of jacking cylinders, the bottom of the cross bar is fixedly arranged on the tops of the guide seats and the jacking cylinders, and the top of the cross bar is provided with a plurality of U-shaped material support grooves.

After receiving the instruction of material jacking, the material jacking cylinder lifts up the steel pipe vertically under the action of the guide seat, and when the steel pipe is sent to the limited space of the C-shaped movable claw, the material-grabbing cylinder pushes the C-shaped movable claw to the same position as the I-shaped movable claw. At the fixed claw, the C-shaped movable claw and the I-shaped fixed claw are in a closed state at this time, so that the steel pipe is supported, and the ejector rack is promptly reset.

The beneficial effect of the utility model lies in that it has the characteristics of low processing cost, high work efficiency, high production safety performance, stable product quality and no burr in the cut.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
