detailed description

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Figures 1-4, the blade cutting device of the present invention includes a ground rail 1, a door-type bracket 2 matched with the ground rail, a sliding frame 3 that is arranged on the beam 21 of the bracket and can be driven to move left and right, And the lower part of the sliding frame is provided with a bearing bracket 4 that can be driven to move vertically up and down, a driven and rotatable hanger 5 is arranged below the bearing bracket, and a vertical belt is arranged on the hanger. Sawing machine 6 and camera.

Specifically, the bracket 2 includes a base 20 corresponding to the ground rail and driven to travel along the ground rail, a column 22 fixedly connected to the base, the end of the beam is fixedly connected to the upper end of the column, and the A guide rail is provided on the upper surface of the beam, a slider matching the guide rail is provided on the sliding frame, and a translation motor is provided on the sliding frame to drive the sliding frame to move relative to the beam through a rack and pinion mechanism. The sliding frame is provided with a vertical guide hole, the bearing bracket is provided with a guide rod matching the vertical guide hole, and the sliding frame is provided with a lifting motor to drive the bearing bracket through a rack and pinion mechanism Move up and down relative to the sliding frame. That is, between the sliding frame and the beam, between the bearing bracket and the sliding frame, the sliding block cooperates with the positioning linear guide rail, the rack and pinion and the motor drive structure to form a sliding truss robot, which executes the horizontal and vertical movement of the cutting head body.

In the blade cutting device of the present invention, the bracket adopts a portal structure and can travel along the ground rail under the axial drive of the driving motor along the belt cutting blade 100, effectively increasing its application range, and moving the vertical band sawing machine by blade positioning way, greatly reducing equipment investment and reducing the burden on enterprises. Wherein, the bracket and the ground rail can adopt any scheme such as roller guide, such as the ground rail adopts a V-shaped guide rail, and the lower part of the base forms a guide groove matching the V-shaped guide rail, and uses the nested V-shaped structure for guidance.

Specifically, a cockpit 7 is correspondingly arranged on the base 20, and a display connected to the camera is arranged in the cockpit. The gantry structure is adopted, and cockpits are respectively set on the bases on both sides of the gantry bracket, that is, two cockpits on the left and right, and a set of operating systems and monitors are installed in each cockpit, and the two sets of operating systems share one The key starts the device, that is, the operating system can be enabled only after the start key is plugged in, so in any case only the operating system on one side can operate the device, so that the cockpit moves in real time to follow the movement of the cutting point, and the operator has a strong sense of operation , the operator can always face the forward direction for cutting, and the direction control handle is consistent with the actual movement direction; if any abnormality occurs, the cutting can be stopped in time; and because of the large operating range, generally at a distance of 70 to 100 meters, the cockpit is used to follow the vertical The follow-up method of the band saw machine avoids problems such as difficult wiring and reduces costs, and with the protection of the cockpit, it can effectively avoid the pollution of cutting dust, and personnel can work at close range.

Specifically, the vertical band sawing machine includes a frame 61 fixedly connected with the hanger and made of high-strength steel plate; The sawing machine motor 63 is based on the vertical elevation of the outer end of the sawtooth on the cutting side of the blade, and the sawing machine motor side is the inner side to process the cutting saw plate frame, and there is no mechanism to interfere with the band saw on the outer side of the band saw blade operation; that is, the basic The racks as a whole are located inside the datum. At the same time, in order to be suitable for sawing structural steel, steel pipe, low-carbon steel or non-metallic materials, the present invention uses diamond band saw blades to ensure the cutting quality of non-metallic materials, especially glass fiber reinforced plastic materials.

Wherein, in order to improve the control effect and improve the cutting accuracy, the rotation axis of the hanger is set concentrically with the side where the outer edge of the sawtooth on the cutting side of the band saw blade is located, that is, the outer edge of the sawtooth on the cutting side of the band saw is located at the rotating On the axis of the shaft, the hanger is driven by a rotary drive motor to rotate relative to the bearing bracket. The rotating mechanism can realize 360-degree free rotation, and the outer edge of the sawtooth is set coaxially with the rotating shaft. When cutting on both sides, the rotating head can be rotated to keep the band saw blade and the blade to be cut in the tangential direction.

Preferably, it also includes a refrigeration mechanism, which includes a cold air outlet arranged inside the band saw of the vertical band saw machine, an industrial air conditioner arranged on the base, and a cold air hose connecting the industrial air conditioner and the cold air outlet. The cold air outlets are arranged on the upper and lower sides of the band saw. Air cooling is adopted to effectively control the temperature of the band saw to ensure that it can work stably for a long time.

At the same time, in order to avoid dust pollution, it also includes a dust suction mechanism, which includes an industrial vacuum cleaner arranged on the base, a collection cup arranged directly under the saw blade, and a dust suction hose connecting the collection cup and the industrial vacuum cleaner. Preferably, the collection cup is also located entirely inside the datum to avoid interference. The dust suction mechanism is used to realize the dust suction during operation. During the cutting process, since the dust mainly occurs directly below the movement of the saw blade, a collection cup is set directly below the saw blade to directly collect the dust brought out by the cutting saw blade. Negative pressure collection cup recovery, due to the small area of the ring-shaped collection pipeline, has the characteristics of energy saving and high efficiency. The dust suction pipeline is equipped with a dust suction hose that moves together with the hanger. The body of the dust collection system is placed on a movable base. Due to the limited amount of dust, a negative pressure industrial dust collection device is used instead of a device similar to bag dust removal, and no low-pressure pump and pulse soot blowing circuit are required to reduce the cost of dust collection.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the protection scope of the present invention.
