Embodiment 1

[0071] The car body wire drawing device of the present invention is applied to the processing of car body parts, especially the wire drawing of the car body surface such as side walls and the like.

[0072] Such as Figure 1 to Figure 3 As shown, the car body wire drawing device consists of two parts, one is the walking device, and the other is the main body of the wire drawing machine. The traveling device is used for the fixation and displacement of the car body parts to be processed, and the wire drawing machine is used for wire drawing of the car body parts to be processed.

[0073] The wire drawing machine includes a column 1, a driving roller 2 distributed in a triangle, a support roller 3 and a tension roller 4, and an abrasive belt 46 is respectively connected to the driving roller 2, support roller 3 and tension roller 4 by belt transmission. The driving roller 2, the support roller The roller 3 and the tension roller 4 are arranged on the periphery of the column 1 i...

Embodiment 2

[0104] Such as Figure 18 , 19 As shown, the car body wire drawing device consists of two parts, one part is the workpiece fixing device (not shown in the figure), and the other part is the main body of the wire drawing machine. The workpiece fixing device is used for fixing the car body parts to be processed, and the wire drawing machine is used for wire drawing of the car body parts to be processed.

[0105] The wire drawing machine includes a wire drawing machine support frame 43, a triangular distribution of drive roll 2, support roll 3 and tension roll 4, the abrasive belt 46 is respectively connected with the drive roll 2, support roll 3 and tension roll 4 as a belt drive, and the wire drawing The top of the machine support frame 43 is provided with a driving motor mounting seat, and a driving motor 5 is arranged in the mounting seat, and the driving motor 5 is connected with the driving roller 2 by a V-shaped belt to drive the driving roller 2 to rotate. The car body ...

Embodiment 3

[0109] Such as Figure 20 to Figure 22 As shown in the figure, a non-painted car body drawing factory building includes four areas, namely the No. 1 preparation station 48, the drawing workshop 49, the No. 2 preparation station 50, and the material and tool storage area 51. The four areas are arranged in a straight line in turn. . The drawing workshop 49 is arranged between the No. 1 preparation station 48 and the No. 2 preparation station 50, and is closed.

[0110] A vehicle body displacement track 52 is set, and the vehicle body displacement track 52 runs through the No. 1 preparation station 48, the drawing workshop 49, and the No. 2 preparation station 50. On the car body displacement track 52, a traction trolley is arranged, and the traction trolley is used to drive the whole row of rail vehicles to move along the No. 1 preparation platform 48, the drawing workshop 49, and the No. 2 preparation platform 50.

[0111] A plurality of wire drawing devices in the first embo...

Abstract

The invention relates to a vehicle wire drawing device and a coating-free railway vehicle. The vehicle wire drawing device comprises a wire drawing machine used for drawing wires of vehicle parts to be machined; the wire drawing machine comprises a sanding belt, a driving roller and a support roller, wherein the sanding belt is in transmission connection with the driving roller and the support roller. A flexible follow-up device is arranged between the driving roller and the support roller and comprises a plurality of grinder rolls, a mandrel and a grinder roll cylinder, wherein the mandrel penetrates the centers of the grinder rolls and the grinder roll cylinder gives constant pressure of the grinder rolls. The grinder roll cylinder is hinged to the mandrel. The vehicle wire drawing device has an open layout and wide breadth, and is easy to draw wires of the vehicle parts in one step without joints. By the flexible follow-up device, influence on quality of wire drawing due to uneven surface of the vehicle parts is overcome. The tensioning mechanism realizes tensioning of the sanding belt and deviation of the sanding belt can be corrected.

Description

technical field [0001] The invention relates to a surface treatment device, in particular to a car body wire drawing device and a non-painted rail vehicle. Background technique [0002] In order to improve the decorative appearance of the rail vehicle body, it is usually used to paint the car body, that is, the surface treatment method of paint coating. The general painting process is: pre-treatment-primer-putty-surfacer-finish , the whole process is cumbersome and time-consuming. [0003] The non-painted car body does not use putty and paint, and reduces the consumption of welding wire and gas. It can not only reduce production costs, but also reduce the weight of the car body and reduce energy consumption. It has distinct technical advantages and competitiveness. Contents of the invention [0004] The main purpose of the present invention is to solve the above problems and deficiencies, and provide a car body wire drawing device that can carry out wire drawing treatment...
