Steel blank straightening device

The present invention relates to a straightening device, and more particularly to a steel blank straightening device.

The old steel straightening machine straightens the steel blank by manpower using the hydraulic jack of the straightening machine. Due to the curved shape and mechanical properties of the steel, it is necessary to manually reciprocate the straightening machine and the straightening support block to adjust the bending point of the steel embryo until the straightness of the steel is in accordance with the process requirements.

However, in the process of straightening a curved steel blank, it is time consuming and laborious to manually reciprocate the straightener. Furthermore, the characteristics of the curved shape and mechanical properties of the steel embryo require manual lifting of the moving support block to the vicinity of the bending point of the steel embryo, and the appropriate distance is adjusted, and the waist of the operator is vulnerable. In view of this, there is a need to propose a solution to solve the above problems.

The invention provides a steel blank straightening device.

In order to achieve the above object, the steel straightening device of the present invention comprises: a vehicle disposed in a recess; a plurality of straightening support blocks disposed in the recess; and an electro-hydraulic jack disposed on the trolley Used to press against the steel embryo to be straightened.

According to the steel blank straightening device of the present invention, it is not necessary to move the trolley by human power at all, so it is quite time-saving and labor-saving. In addition, due to straightening The roller is equipped with a roller, and no manual lifting is required during the operation, and the operator has no wrestling or a sprained waist. Since the wrench has a sealed type of ferrule, during the process of turning over the steel slab, the steel slab will not slip off, posing a risk of collision hazard.

The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described.

Referring to Figures 1 and 2, the steel blank straightening apparatus of the present invention includes a cart 110 disposed within an elongated recess 170. The trolley 110 is provided with a driver 112, such as a starter motor of a vector controlled inverter, which drives the gears to move the carriage 110 over the rack 130 in the recess 170. In addition, an electric hydraulic jack 120 is mounted on the trolley 110. The steel blank straightening device of the present invention further comprises a plurality of straightening support blocks 180 disposed in the recess 170, the bottom of which is provided with a roller 182 for facilitating movement within the recess 170. In addition, a shackle 184 is further disposed on the straightening support block 180 for the operator to drag.

Referring to Figures 3a and 3b, in order to use the steel blank straightening device of the present invention, the steel blank 190 to be straightened is placed in the groove 170, and the steel support 190 is held by the straightening support block 180. The drive 112 is then controlled to move the dolly 110 to the position to be straightened. Then operate The electro-hydraulic jack 120 is extended to press against the steel blank 190. After a period of time, the electro-hydraulic jack 120 is retracted. Then move the trolley 110 to another position to be straightened and repeat the above action.

Referring to Figure 4, since the steel blank 190 may need to be turned during the straightening process, the steel blank straightening apparatus of the present invention further includes a turning device 160 composed of a wrench 162 and a motor driven arm 164. The wrench 162 can be a ratchet wrench that rests on the motor drive arm 164, which can be constructed of an aluminum alloy material. Referring to Figures 5a and 5b, when the inverting device 160 of the present invention is used to invert the steel preform 190, the sealing sleeve 166 of the wrench 162 is placed over one end of the steel blank 190. Then, the motor is driven to rotate the arm 164, and the wrench 162 is rotated to invert the steel preform 190.

Referring to Fig. 6, a steel blank straightening apparatus according to the present invention, wherein the electro-hydraulic jack 120, the driver 112 of the dolly 110, and the motor-driven arm 164 of the turning device 160 can be controlled in a wired or wireless manner. That is, the electro-hydraulic jack 120, the driver 112, and the motor-driven arm 164 are coupled to a controller 150 in a wired or wireless manner, by which the straightening of the steel 190, the trolley 110 is controlled. Movement and flipping of the steel embryo 190. In order to avoid damage to the device, a detector 152 may be disposed on the trolley 110 and coupled to the controller 150 for detecting whether the electro-hydraulic jack 120 has been retracted. When the controller 150 borrows When the detector 152 detects that the electro-hydraulic jack 120 is not retracted, the driver 112 is locked so that it cannot be started. That is to say, when the electro-hydraulic jack 120 is not retracted, the trolley 110 cannot be moved to avoid damage to the electro-hydraulic jack 120. In addition, the present invention can also be provided with a detector 154 coupled to the controller 150 for detecting whether the trolley 110 exits the straightening site to a point location. When the controller 150 detects that the trolley 110 is not at the starting position by the detector 154, it locks the motor driving arm 164 to make it unable to rotate. That is, when the cart 110 is not at the starting position, the motor-driven arm 164 cannot be rotated to avoid inadvertently turning over the billet 190 and damaging the equipment on the cart 110. Further, the present invention can also be provided with a detector 156 coupled to the controller 150 for detecting whether the position of the motor-driven arm 164 is returned to the origin. When the controller 150 detects that the motor driving arm 164 is not at the origin position by the detector 156, the hydraulic jack 120 is locked to be unactivated. That is to say, when the motor driving arm 164 is not at the origin position, the straightening of the steel 190 cannot be performed, so as to prevent the wrench 162 from being erected on the steel 190, and the vibration is caused by the straightening of the steel 190. Go to the wrench 162 and pour it down, damaging the equipment or injuring people.

According to the steel blank straightening device of the present invention, the trolley 110 is not required to be manually moved, so that it is time-saving and labor-saving. In addition, since the roller is mounted on the straightening support block 180, no manual lifting is required during the operation, and the operator has no wrestling or a sprained waist. And because of the wrench The 162 series has a sealing type ferrule 166, which does not cause the steel slab 190 to slip off during the process of turning over the steel emboss 190, posing a risk of collision hazard.

While the present invention has been disclosed by the foregoing examples, it is not intended to be construed as limiting the scope of the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
