Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

As shown in Figure 1-2, an easy-to-operate bending machine for a construction site includes a workbench 1 and a support frame 8. The top of the workbench 1 is provided with a placement plate 2, and both sides of one end of the workbench 1 are fixed with Fixed frame 4, the top of fixed frame 4 is provided with fixed plate 13, is fixedly connected with one end of pressing plate 3 by rotating shaft 14 between two fixed plates 13, and one side of pressing plate 3 is fixed with four fixed pin sleeves 6 by screw, And the four fixed pin sleeves 6 are interspersedly connected with the U-shaped handle 5; the bottom of the workbench 1 is fixedly provided with a support frame 8, and the bottom of the support frame 8 is fixedly provided with a fixed base plate 9, and the fixed base plate 9 is fixedly connected with the ground by pins .

Wherein, one side of placing plate 2 is provided with positioning plate 7, and one end of positioning plate 7 is fixedly connected with the top of workbench 1 through rotating shaft table 12, and the other end of positioning plate 7 is provided with pin hole 15, and positioning plate 7 passes pin hole 15 and the pin bar 11 are fixedly connected with the workbench 1, put the steel plate or steel bar to be bent on the top of the placement plate 2, rotate the positioning plate 7, make the positioning plate 7 rotate around the top of the rotating shaft table 12, and pass the pin bar 11 Through the pin hole 15 on one side of the positioning plate, the positioning plate 7 is fixed, and at the same time, ensure that the steel is in the gap formed between the positioning plate 7 and the placing plate 2, and the steel will move during the bending process.

Wherein, the middle part of the U-shaped handle 5 is covered with a non-slip soft cover. After fixing the position of the steel material, by pressing the U-shaped handle 5 downward, the U-shaped handle 5 is rotated around the rotating rod 14, thereby bending the steel material. During repeated operations, there will be constant friction between the palm of the hand and the U-shaped handle 5, and the added anti-skid soft cover can only ensure that the hand does not slip during the operation, and at the same time, it can protect the palm of the operator to a certain extent .

Wherein, the opposite side of the placement plate 2 and the positioning plate 7 is provided with a groove 10 correspondingly. When bending the round steel material of the steel bar lamp, such steel material can be placed in the groove 10, and the circular steel material can be bent by using the groove 10. Shaped steel for effective positioning.

Among them, the pressure plate 3 is made of hard alloy steel. Since the steel body exerts a reaction force on the pressure plate during the bending process of the steel, making the pressure plate with a material with high strength and hardness can ensure that the equipment remains stable after multiple uses. Good working performance.

Wherein, one end of the placing plate 2 and one end of the pressing plate 3 are arranged on the same vertical line, so that the pressing plate can squeeze the steel easily and ensure the bending effect.

Wherein, the side of the pressing plate 3 is engraved with a scale line, and the length of the steel production workbench 1 can be easily read through the set scale line, thereby improving the processing accuracy of the equipment to a certain extent.

It should be noted that the utility model is an easy-to-operate bending machine for a construction site. During specific operation, put the steel plate or steel bar to be bent on the top of the placement plate 2, and rotate the positioning plate 7 so that the positioning plate 7 Rotate around the top of the rotating shaft table 12, clamp the steel plate through the positioning plate 7 and the placing plate 2, so that the steel plate is fixed in the gap formed between the positioning plate 7 and the placing plate 2, and avoid the steel plate from moving during the bending process , which affects the bending effect; by moving the steel plate, one end of the steel plate protrudes out of the working table 1, and the scale line engraved on the side of the pressing plate 3 can be used to read the length of the steel plate protruding out of the working table to determine the bending After the length is reached, firmly press the U-shaped handle 5 to rotate the pressing plate 3 around the rotating shaft 14 through the U-shaped handle 5, and bend the steel plate protruding from the workbench 1. After the bending is completed, during the bending process It is often encountered that the difficulty of bending is different due to the difference in the plate. For the steel plate with stronger hardness, the external force required for bending is also increased accordingly. When bending the steel plate with stronger hardness, it can be pulled outward. The U-shaped handle 5 separates the U-shaped handle 5 from the fixed pin sleeve 6 near the side of the rotating shaft 14, and at the same time ensures that one end of the U-shaped handle 5 is still set in the fixed pin sleeve 6 near the outside of the pressure plate 3. According to the principle of leverage, Under the condition of constant force, increasing the force arm can effectively increase the force effect, thereby smoothly bending the steel plate; when bending the steel bar, place the steel bar in the groove 10 provided on the top of the placing table 2 , the steel bar is positioned through the groove 10 to reduce the movement of the steel bar.
