Description

Technical Field

[0001] The utility model relates to the technical field of steel plate pre-bending, in particular to a pre-bending device which is convenient for using steel plates with different specifications. Background Art

[0002] Orthopedics is a branch of medicine that specializes in the study and treatment of diseases and injuries of the skeletal system (including bones, joints, muscles, ligaments, etc.). Plate pre-bending devices are commonly used in orthopedic surgery, especially in fracture repair. This device can help surgeons pre-bend the plate before surgery to adapt to specific anatomical structures or fracture conditions.

[0003] In some existing pre-bending devices, the distance between the clamps is usually fixed and difficult to adjust. It is troublesome to pre-bend steel plates of different specifications. In addition, such pre-bending devices can usually only bend the edges of steel plates. When bending the steel plates in the middle, other types of devices are usually required, which is less practical.

[0004] Therefore, those skilled in the art provide a pre-bending device that is convenient for use with steel plates of different specifications to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a pre-bending device which is convenient for using steel plates of different specifications. The three bolts are manually rotated, and then the second L-shaped plate is pulled to the frontmost side. Then, the first L-shaped plate is pulled upward while the steel plate is placed on the lower end of the first L-shaped plate. At this time, the bidirectional screw rod is rotated, and the steel plate is moved to the middle position through the two second sliders against the steel plate. After it is placed, the second L-shaped plate is pulled to a suitable position according to the bending angle, and then the three bolts are turned back. At this time, the motor is controlled by the infrared sensor to move the push plate to the surface position of the steel plate. Finally, the electric telescopic rod is opened to control the push rod to move downward, so as to bend the edge of the steel plate. By setting the first fixing mechanism and the positioning mechanism, it is possible to bend different positions of steel plates of different specifications, which is more convenient.

At this time, the steel plate can be bent in the middle. By setting a second fixing mechanism and two rotating plates, the steel plate can be bent at the edge and in the middle, thereby improving practicality. BRIEF DESCRIPTION OF THE DRAWINGS

The fixed plate 201 is fixedly connected to the base 101, the first L-shaped plate 202 is fixedly connected to the fixed plate 201 by bolts, the connecting plate 203 is fixedly connected to the first L-shaped plate 202, the extension plate 204 is fixedly connected to the connecting plate 203 by bolts, the extension plate 204 is fixedly connected to the slide plate 205, the second L-shaped plate 206 is fixedly connected to the slide plate 205 by bolts, and the slide plate 205 is slidably arranged through the middle position of the upper side of one side end surface of the base 101.

[0034] The bolts on the surfaces of the connecting plate 203, the first L-shaped plate 202 and the second L-shaped plate 206 are manually rotated, and then the second plate is pulled to the front. At this time, the first L-shaped plate 202 is pulled upward while the steel plate is placed at the lower end of the first L-shaped plate 202. When the steel plate is placed, the baffle plate set on the rear end face of the fixing plate 201 is used to limit the steel plate so that when the steel plate is pushed in from the front, it will not be pushed out of the lower end of the first L-shaped plate 202. After placing it, the bidirectional screw rod 208 is rotated, and the bidirectional screw rod 208 drives the two second sliders 209 on the surface to move toward the middle. The two second sliders 209 are abutted against the steel plate, thereby driving the steel plate to the middle position. At this time, according to the required bending position, the second L-shaped plate 206 is pulled toward the rear side. When it moves to the appropriate position, the three bolts are manually turned back to fix the steel plate inside the first fixing mechanism 2.

[0035] An electric telescopic rod 106 is embedded in the middle position of the lower end surface of the first slider 105, and a push rod 107 is fixedly arranged at the output end of the electric telescopic rod 106. The cover plate 102 is fixedly connected to the base 101, and the screw rod 103 is rotatably arranged on the side of the front end surface of the cover plate 102.

In the middle position of the front side, before putting in the steel plate, the electric telescopic rod 106 should drive the push rod 107 to the uppermost end. After the steel plate is placed, the infrared sensor 108 measures the distance moved by the front support plate 207, and then controls the motor 104 to drive the screw rod 103 to rotate. During the rotation of the screw rod 103, the first slider 105 is controlled to move forward, thereby moving the push rod 107 to the edge of the steel plate, and then the electric telescopic rod 106 is opened, and the electric telescopic rod 106 drives the push rod 107 to move downward, thereby bending the steel plate.

[0036] A rotating plate 109 is rotatably arranged at the front and rear sides between the inner walls on both sides of the base 101. The second fixing mechanism 3 includes a hand-pull plate 301, a third L-shaped plate 303 and two clamping plates 304. Two return springs 302 are fixedly arranged between the hand-pull plate 301 and the base 101. The hand-pull plate 301 is slidably arranged on the upper side of the end surface of the other side of the base 101. The third L-shaped plate 303 is fixedly connected to the hand-pull plate 301. The two clamping plates 304 are respectively fixedly arranged at the upper and lower sides of the inner wall of one side of the third L-shaped plate 303. When the middle of the steel plate is bent, the first L-shaped plate 303 is manually rotated to rotate. The bolts on the surface of the L-shaped plate 202 and the second L-shaped plate 206 are then pulled to one side while pulling the hand-pull plate 301 and the supporting plate 207 upwards. When it cannot move further, put the hand-pull plate 301 back for a distance, and then rotate the two rotating plates 109 to a horizontal position. Finally, release the pull on the hand-pull plate 301, and the two protrusions on the surface of the hand-pull block enter into the inner wall of the rotating shaft of the two rotating plates 109, thereby fixing the two rotating plates 109 and the base 101 together. Then put the steel plate on the surface of the two rotating plates 109, and then the steel plate can be bent in the middle.

[0037] Working principle: manually turn the three bolts, then pull the first L-shaped plate 202 upwards while passing the steel plate through the lower end of the second L-shaped plate 206 and pushing it into the lower end of the first L-shaped plate 202. After placing it, release the pull on the first L-shaped plate 202, and then turn the bidirectional screw rod 208 to push the steel plate to the middle position. At this time, according to the bending angle, pull the second L-shaped plate 206 to the appropriate position, and then turn the three bolts back. At this time, turn on the infrared sensor 108 and the motor 104. The infrared sensor 108 controls the motor 104 to drive the push rod 107 to move to the edge of the steel plate, and then opens the electric telescopic rod 106 to bend the steel plate. When bending in the middle, the hand-pull plate 301 is pulled to one side while the support plate 207 is pulled upward. When it cannot be pulled further, the hand-pull plate 301 is put back for a distance, and then the two rotating plates 109 are rotated to a horizontal position. At this time, the hand-pull plate 301 is released, and finally the steel plate is placed on the surface of the two rotating plates 109.
