The front fixing seat and the rear fixing seat are arranged oppositely, and there are two mounting frame plates, all of which are correspondingly arranged on the front and rear fixing seats through mechanical ejector pins or hydraulic ejector pins, and the mounting frame plates are detachably connected with molds.

Further, the bottom surface of the turnover plate body is an arc-shaped surface.

Further, a clamping plate is provided on the clamping end surface of the locking screw.

The beneficial effects of the utility model are: the turning device is simple in structure and low in cost, and can meet the requirements of testing and production of workpieces with a radius greater than 1500 mm and an angle of more than 30°; it can realize up and down bending and front and rear side bending, which is convenient and fast. The jacking method has changed the previous situation of manually smashing the inclined iron; it is easy to operate and improves the production efficiency of bending; the placement position of the split tooling can be adjusted according to the cross-section of different workpieces to meet the diverse needs of production.

Description of drawings

In order to make the purpose, technical solutions and beneficial effects of the utility model clearer, the utility model provides the following drawings for illustration:

Fig. 1 is the structural representation of the utility model;

Figure 2 is a schematic diagram of the use state.

Detailed ways

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in the figure, the split-type profile bending multifunctional turning device in this embodiment includes a turning plate 1 and a bending and clamping device 2. There are two turning plates 1 that can be detachably installed on the workbench 3 at intervals. , the bending and clamping device 2 is correspondingly arranged between the two turning plates 1; the turning plate 1 is mainly composed of a support 11 and a turning plate body 12 arranged on the support 11, and the turning plate body 12 passes through A rotating shaft 13 is rotatably connected to the support 11 and positioning plates 14 are provided on both sides of the flip plate body 12, and locking screws 15 are provided on the positioning plates 14; the bending and clamping device 2 is mainly fixed by the front Seat 21, rear fixed seat 22 and installation frame plate 23, described front fixed seat 21 and rear fixed seat 22 are arranged oppositely, and described installation frame plate 23 has two, all are arranged in front and rear by hydraulic ejector rod 24 correspondingly on the fixed seat, and the mounting frame plate 23 is detachably connected with a mold.

Specifically, the overturning device adopts a split structure, which can be installed using the length of the workbench 3, and the specific distance between the overturning plate 1 and the bending and clamping device 2 can be adjusted; that is, according to the actual specifications of the workpiece and the determined deformation data , based on the actual center of the workbench, locate the two turning plates on the workbench, and determine and fix the position of the bending and clamping device 2 according to the equal division theory.

When using this device for bending up and down, place the workpiece 4 on the two flipping plates 1, ensure that the flipping plate body 12 in the two flipping plates 1 is in a horizontal state and adjust the workpiece to be at the center of the two flipping plates 1, and the knob locks the screw 15. Lock the workpiece at the center of the two turning plates 1 to achieve corrective clamping, adjust the bending clamping device 2, make the mold clamp the workpiece 4, release the locking screw 15, press the bending machine to work, and the two ends of the workpiece The turnover plate 1 deflects accordingly.

When using the device for front and rear side bending, place the workpiece on the two flipping plates 1, ensure that the flipping plate body 12 in the two flipping plates 1 is in a horizontal state and adjust the workpiece to be at the center of the two flipping plates 1, use the flipping plate body 12 The positioning plates 14 on both sides do front and rear lateral positioning of the workpiece (straight profile), and the hydraulic ejector rod 24 in the bending clamping device 2 on the front or rear side acts to realize the small lateral bending of the workpiece.
