Description

Technical Field

[0001] The utility model relates to the technical field of angle steel drilling, in particular to an angle steel drilling die with a protective structure. Background Art

[0002] Angle steel drilling generally adopts hydraulic method to perform drilling operation. When drilling, the angle steel is first placed in the mold, and then the drilling device is started to drill the angle steel. The existing mold is generally made of alloy. The mold mainly plays the role of positioning and locking, which facilitates the drilling device to drill accurately. During the operation, the mold and the drill bit will produce contact friction with the angle steel.

[0003] This type of mold has high requirements for processing precision and lacks protective measures. With long-term use, when the angle steel is placed in the mold and drilled, the mold and drill bit will gradually be worn by the angle steel, and the position of the angle steel will shift. At the very least, the drilling position accuracy is insufficient, and at worst, the angle steel will be damaged.

[0004] Therefore, in order to solve the problem that the processing position is offset due to the wear of the angle steel in the existing mold, a method is designed to reduce the friction between the angle steel and the mold drill bit to avoid the wear problem. Utility Model Content

[0005] In order to overcome the problem that the existing mold is worn by the angle steel and causes the processing position to shift.

[0006] The technical solution of the utility model is: a mold for drilling angle steel with a protective structure, comprising a mold main body, a drill hole, a cylinder one and a cylinder two; also comprising a connecting rod one and a connecting rod two; a drill hole is provided at the center of the upper end of the mold main body, a cylinder one is fixedly installed on the upper end of the mold main body, the piston rod end of the cylinder one is fixedly connected to the connecting rod one, and the connecting rod one is arranged through the top surface of the mold main body, a cylinder two is fixedly installed on the upper end surface of the mold main body, the piston rod end of the cylinder two is fixedly connected to the connecting rod two, and the connecting rod two is arranged through the top surface of the mold main body, a cylindrical through-type opening is provided at the lower end of the mold main body, and the cylindrical through-type opening at the lower end of the mold main body is opposite to the drill hole at the upper end of the mold main body, a protective mechanism for protecting the angle steel through lubrication is provided inside the mold main body, and limiting mechanisms for positioning the angle steel are provided on both sides of the mold main body.

[0007] Preferably, first adjust the distance between the two rollers according to the size of the angle steel, and slide the slider on the slide rail at the upper end of the base. When it is adjusted to the appropriate position, adjust the distance between the rollers on both sides of the mold body, and then put the angle steel into the mold body. Due to the use of rollers, compared with the traditional method of directly putting it into the mold, the utility model successfully avoids the friction between the angle steel and the two sides of the mold, and is suitable for processing angle steels of different sizes. Connect cylinder one and cylinder two to the air pump. Under the action of cylinder one and cylinder two, the rubber pads at the two ends of the connecting rod fix one end of the angle steel, and the steel oil storage box at one end of the connecting rod fixes the other end of the angle steel. In this process, when the bottom of the steel oil storage box presses the angle steel, the pressure sensor senses the pressure and transmits an electrical signal to the electronic valve. The electronic valve opens, and the lubricating oil in the steel oil storage box flows out, reducing the heat generated during drilling and reducing the friction between the angle steel and the bottom surface of the mold body. After the connecting rod rises, the pressure sensor loses pressure, and the electronic valve closes again, saving oil usage.

[0008] Preferably, the protection mechanism includes a steel oil storage box, an electronic valve, a pressure sensor, an oil tank, a cover, an oil hose and a rubber pad. The end of connecting rod one is fixedly connected to the steel oil storage box, one end of the steel oil storage box is fixedly connected to the electronic valve, one side of the steel oil storage box is fixedly connected to the pressure sensor, the oil tank is fixedly installed on one side of the mold body, the upper end of the oil tank is threadedly connected to the cover, one side of the oil tank is fixedly connected to the oil hose, the other end of the oil hose is fixedly connected to one side of the steel oil storage box, the end of connecting rod two is fixedly connected to the rubber pad, the rubber pad at the end of connecting rod two fixes one end of the angle steel, and the steel oil storage box at the end of connecting rod one fixes the other end of the angle steel, ensuring that the angle steel will not shift during drilling.

[0009] Preferably, a cavity is provided inside the steel oil storage box, and one end of the electronic valve is connected to the internal cavity of the steel oil storage box. When the bottom of the steel oil storage box presses the angle steel, the pressure sensor senses the pressure and transmits an electrical signal to the electronic valve. The electronic valve opens, and the lubricating oil in the steel oil storage box flows out. Once the connecting rod rises, the pressure sensor loses pressure and the electronic valve closes again, thereby saving the use of lubricating oil.

[0010] Preferably, one side of the mold body is provided with a cylindrical through hole for the oil hose to pass through, and the lower end of the steel oil storage box is provided with anti-slip grooves. The anti-slip grooves of the oil storage box enable the oil storage box to better press the angle steel under the action of cylinder 1.

[0012] Preferably, an opening is provided at the upper end of the beam for movement of the positioning shaft, a slide groove is provided on one side of the beam for sliding of the positioning handle, and the surface of the positioning handle is provided with anti-slip grooves. The opening of the beam facilitates the movement of the positioning handle, and the anti-slip grooves on the surface of the positioning handle facilitate the staff to tighten it by hand.

[0013] Preferably, one side of the beam has a frosted surface, and the end of the positioning handle is fixedly connected with an annular rubber ring. When the positioning handle is tightened, the annular rubber ring of the positioning handle fits tightly against the frosted surface of the beam, thereby increasing friction and ensuring stability during processing.

[0014] The beneficial effects of the utility model are:

[0015] 1. After the distance between the rollers on both sides of the mold body is adjusted, the angle steel is placed into the mold body. Due to the use of rollers, compared with the traditional method of directly placing the angle steel into the mold, this utility model successfully avoids the wear problem caused by the friction between the angle steel and the two sides of the mold, so that the angle steel can be smoothly placed into the mold and is suitable for processing angle steels of different sizes.

[0016] 2. When the bottom of the steel oil storage box presses the angle steel, the pressure sensor senses the pressure and transmits an electrical signal to the electronic valve. The electronic valve opens and the lubricating oil in the steel oil storage box flows out, reducing the heat generated during drilling and the friction between the angle steel and the bottom surface of the mold body. Once the connecting rod rises, the pressure sensor loses pressure and the electronic valve closes again, saving oil. BRIEF DESCRIPTION OF THE DRAWINGS

The electronic valve 6 opens, and the lubricating oil in the steel oil storage box 5 flows out. After the connecting rod 1 4 rises, the pressure sensor 7 loses pressure, and the electronic valve 6 closes again.
