Description

Technical Field

[0001] This utility model belongs to the field of elevator door manufacturing technology, and is particularly related to an elevator door panel bending device. Background Technology

[0002] During elevator door production, a rectangular steel plate needs to be bent on both sides until it is perpendicular to the main body of the plate. Reinforcing ribs are then welded between the two bent sections. Currently, bending the steel plate is usually done in two steps: first bending one side, then the other. Bending a single steel plate requires two repositioning operations, which is inefficient. Furthermore, because the steel plate is heavy, these two repositioning operations are labor-intensive. Therefore, an improvement is necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides an elevator door panel bending device that can simultaneously bend both sides of a steel plate, thereby improving production efficiency.

[0004] To achieve the above objectives, the present invention employs the following technology:

The second bidirectional telescopic mechanism is used to drive the pair of lower pressure bars to move synchronously in opposite directions.

[0010] Furthermore, the first bidirectional telescopic mechanism includes a pair of staggered synchronous rods, and the middle of each pair of synchronous rods is rotatably connected to a rotating shaft. The rotating shaft is fixed on a support column, which is located between a pair of vertical support plates. Both ends of the top surface of the synchronous rods are provided with vertical push columns. The bottom of each second support rod is provided with a strip-shaped groove along its length. The two push columns located at one end of the pair of synchronous rods are slidably connected in a strip-shaped groove, and the two push columns located at the other end of the pair of synchronous rods are slidably connected in another strip-shaped groove. One of the synchronous rods is hinged to the telescopic end of a horizontally arranged linear mechanism, and the fixed end of the linear mechanism is hinged to the inner side of a vertical support plate.

The pair of lower pressure bars are threadedly connected to the two threaded sections respectively.

[0012] Furthermore, an inverted U-shaped support frame is provided across both ends of a pair of vertical support plates. The fixed end of the second lifting mechanism is connected to the bottom of the transverse section of the inverted U-shaped support frame. A base plate is provided at the bottom of the inverted U-shaped support frame.

However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0024] This application provides an elevator door panel bending device, such as... Figures 1-6 As shown, it includes a first support rod 1, a vertical frame 4, and a lower pressure plate 6.

[0025] Specifically, there is a pair of first support rods 1, which are mounted on top of a pair of vertical support plates 2. A pair of second support rods 3 are vertically mounted above the pair of first support rods 1. The two vertical sections of a pair of vertical frames 4 are slidably connected to the two ends of the pair of second support rods 3 in the vertical direction. The top of the lower horizontal section of the pair of vertical frames 4 is connected to the movable ends of two first lifting mechanisms 5. The fixed ends of the two first lifting mechanisms 5 are connected to the bottom of the pair of second support rods 3. The lower pressure plate 6 is located above the pair of vertical frames 4.

The pair of second support rods 3 are located between the pair of lower pressure strips 601, and the horizontal distance between the pair of second support rods 3 and the lower pressure strips 601 on the same side is equal.

[0026] In actual use, first control the first lifting mechanism 5 to drive the vertical frame 4 to rise, then place the rectangular steel plate 14 above the second support rod 3, so that the two sides of the steel plate 14 protrude a certain distance outside the two second support rods 3. Next, control the first lifting mechanism 5 to drive the vertical frame 4 to fall, so that the top of the vertical frame 4 presses the steel plate 14 tightly. Then control the second lifting mechanism 7 to fall, and press down the part of the steel plate 14 protruding outside the two second support rods 3 through a pair of lower pressure bars 601, so that it bends downward by 90 degrees, thus achieving simultaneous bending of both sides of the steel plate 14.

[0027] For details, please refer to Figure 1 A pair of vertical support plates 2 are connected at both ends by an inverted U-shaped support frame 11. The fixed end of the second lifting mechanism 7 is connected to the bottom of the horizontal section of the inverted U-shaped support frame 11. A base plate 12 is provided at the bottom of the inverted U-shaped support frame 11. Two pairs of second guide rods 13 are provided between the base plate 12 and the horizontal section of the inverted U-shaped support frame 11. The lower pressure plate 6 is slidably connected to the two pairs of second guide rods 13 to improve the stability of the lower pressure plate 6 moving up and down.

[0028] Preferred options, please refer to Figure 3 , Figure 4 Each pair of first support rods 1 has a T-shaped groove 101 at its top along its length, and each pair of second support rods 3 has a pair of T-shaped sliders 301 at its bottom. The pair of T-shaped sliders 301 are slidably connected within the pair of T-shaped grooves 101. A first bidirectional telescopic mechanism is provided between the pair of second support rods 3, which is used to drive the pair of second support rods 3 to move synchronously in opposite directions. A pair of lower pressure strips 601 are connected to a second bidirectional telescopic mechanism, which is fixed to the bottom of the lower pressure plate 6. The second bidirectional telescopic mechanism is used to drive the pair of lower pressure strips 601 to move synchronously in opposite directions. When the width of the door panel to be bent is different, the distance between the pair of second support rods 3 can be changed by the first bidirectional telescopic mechanism, and the distance between the pair of lower pressure strips 601 can be changed by the second bidirectional telescopic mechanism to adapt to bending of steel plates 14 for making door panels of different widths.

[0029] For details, please refer to Figures 3-5The first bidirectional telescopic mechanism includes a pair of staggered synchronous rods 8, and the middle of each pair of synchronous rods 8 is rotatably connected to a rotating shaft 801. The rotating shaft 801 is fixed on a support column 802, which is located between a pair of vertical support plates 2. Both ends of the top surface of the synchronous rods 8 are vertically provided with cylindrical push columns 803. The bottom of the second support rods 3 are provided with strip grooves 302 along their length direction. The two push columns 803 located at one end of the pair of synchronous rods 8 are slidably connected in a strip groove 302, and the two push columns 803 located at the other end of the pair of synchronous rods 8 are slidably connected in another strip groove 302. One of the synchronous rods 8 is hinged to the telescopic end of a horizontally arranged linear mechanism 804. The fixed end of the linear mechanism 804 is hinged to the inner side of a vertical support plate 2. Specifically, the linear mechanism 804 is a hydraulic cylinder. By extending the telescopic end of the linear mechanism 804, a pair of second support rods 3 can move towards each other; by retracting the telescopic end of the linear mechanism 804, a pair of second support rods 3 can move in opposite directions. The distance between the pair of second support rods 3 can be controlled by controlling the extension distance of the linear mechanism 804.

[0030] For details, please refer to Figure 6 The second bidirectional telescopic mechanism includes a screw 9 and a rotary motor 10. A rectangular groove 602 is formed at the bottom of the lower pressure plate 6. A pair of first guide rods 603 are arranged within the rectangular groove 602 along the width direction of the lower pressure plate 6. A pair of lower pressure strips 601 are located within the rectangular groove 602 and are slidably connected to the pair of first guide rods 603. The screw 9 is rotatably positioned within the rectangular groove 602 and is parallel to the first guide rods 603. One end of the screw 9 is connected to the output shaft of the rotary motor 10. The two ends of the screw 9's periphery are respectively provided with threaded sections 901 with opposite directions of rotation. The pair of lower pressure strips 601 are threadedly connected to the two threaded sections 901 respectively. By controlling the rotary motor 10 to drive the screw 9 to rotate, the two threaded sections 901 with opposite directions of rotation of the screw 9 can drive the pair of lower pressure strips 601 to move along the width direction of the lower pressure plate 6, thereby adjusting the distance between the pair of lower pressure strips 601 to accommodate bending of steel plates 14 used to make door panels of different widths.
