Problems solved by technology

[0004] In order to make the appearance of the vehicle beautiful, the current rail transit industry adopts bending deformation of the plate to make it have a certain streamlined shape and increase the aesthetic feeling, and there are already some bending forming devices (Chinese patent CN 103357797 B) that can realize bending deformation of the plate, but There are many factors that affect the bending angle in the actual use of the existing bending forming device, it is difficult to accurately control the bending angle, and at the same time, it is impossible to realize the twist deformation and forming of thick plates (thickness equal to 80mm or above)
At present, the thick plate machining method is usually used for thick plates (thickness equal to 80mm or above), that is, the raw material of the plate is thickened, and the thickness includes the curved part of the plate, and then the machining method is used to mill and form, but this method Complicated operation, high cost and low efficiency

Embodiment 1

[0022] Embodiment 1 Plate distortion forming device

[0023] refer to figure 1 , the forming device of the present invention includes: a hydraulic base station 1, a gantry press 2 connected to the hydraulic base station 1, a twisting device 3 arranged on the gantry press 2, and a fastening device 4 for fixing a plate; wherein, the The gantry press 2 includes a platform 21, a U-shaped gantry 22 arranged on the platform, a hydraulic cylinder 23 arranged on the U-shaped gantry 22 and connected to the hydraulic base station 1 through a hydraulic pipeline 5, and one end of the hydraulic cylinder 23 is provided There is a clip 24 engaged with the twisting device 3 .

[0024] refer to figure 2 , image 3 , the torsion device 3 includes two torsion plates 31 symmetrically arranged, the two torsion plates are insole type, the torsion plate 31 includes a small ellipse connecting end 311 and a large ellipse torsion end 312, the small ellipse of the two torsion plates A standpipe 32 ...

Embodiment 2

[0027] Embodiment 2 Use the sheet material twisting forming device described in Example 1 to carry out a 500mm long sheet material

[0028] Rows are twisted into shape.

[0029] 1. Adjust the twisting device 3 so that the feeding port 37 on the twisting device 3 and the connecting shaft 35 are on the same horizontal line (such as image 3 shown); then insert one end of the plate to be formed with a length of 500 mm into the feed ports 37 of the two twisted plates, so that the plate is most suitable for 50 mm exposed at the end of the twisting device, which saves the cost of the plate and does not affect the twisting forming; The other end of the plate is fixed on the platform 21 using a fastening device 4;

[0030] 2. Connect the jig 24 on the gantry press 2 with the concave plate 33 on the twisting device 3, start the hydraulic base station 1, and make the hydraulic cylinder 23 move downward. The pressure generated by the hydraulic cylinder 23 when it moves up and down is 50...

Abstract

The invention discloses a plate twisting formation device and method. The formation device comprises a hydraulic base station, a gantry type press machine connected with the hydraulic base station, a twisting device arranged on the gantry type press machine and a fastening device for fixing plates, wherein the gantry type press machine comprises a platform, a U-shaped gantry arranged on the platform and a hydraulic cylinder arranged on the U-shaped gantry and connected with the hydraulic base station through a hydraulic pipe, and a clamp clamped with the twisting device is arranged at one end of the hydraulic cylinder. The twisting device comprises two twisting plates, wherein each twisting plate comprises small oval connecting ends and large oval twisting ends, a vertical tube is arranged between the small oval connecting ends, the small oval connecting ends are connected through a connecting shaft, and a concave plate is arranged on the vertical tube and is rightly clamped with the clamp. The large oval twisting ends are fixed through a connecting plate. A rectangular feeding port is further formed in each large oval twisting end and is used for placing the plates. The formation device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a plate twist forming device and forming method. Background technique [0002] At present, rail transit has the most advantages among all transportation means in the city because of its fast, safe, and punctual characteristics. With the progress of society and the development of economy, many cities in our country have subways or light rails. The comfort, speed and convenience of subways or light rails have become an important means of transportation for people to travel. [0003] With more and more functions of subway trains and the continuous development of technology, its appearance is also advancing with the times. Different models are different due to their different regions and historical backgrounds, but they remain the same. It is very necessary to improve the overall aesthetic level of rail vehicle exterior design. [0004] In order to make the appearance of the vehicle...
