The positioning baffle 230 is driven by the positioning thruster 220 to switch between a position of extending into the roll gap of the anti-toppling roller bed 130 and a position of retracting below the anti-toppling roller bed 130. When blanking operation is required, the positioning pushing device 220 drives the positioning baffle 230 to extend upwards and extend into a roll gap of the anti-toppling roller way 130, the part of the positioning baffle 230 located above the anti-toppling roller way 130 can prevent the profile 600 from moving forwards, the distance between the positioning baffle 230 and the die cutting edge of the punch C is equal to the length of the jamb 500, and when the die cutting edge of the punch C cuts the profile 600, a jamb 500/jamb 500 blank meeting the set length can be obtained. The counter force is provided by the frame 110 of the anti-toppling roller conveyor 100D of the positioning section D and the supporting frame 210 of the positioning assembly 200 during the blanking process.

Specifically, threaded through hole and direction unthreaded hole have been seted up in mount pad 240, fine setting double-screw bolt 270 runs through threaded through hole, install in mount pad 240, accessible bulb or bearing realize rotating between one end of fine setting double-screw bolt 270 and the positioning baffle 230 and be connected, fine setting double-screw bolt 270's one end mounting nut, and set up prismatic structure at this tip, conveniently rotate this fine setting double-screw bolt 270, can realize the position fine tuning of positioning baffle 230 on the direction of transportation through fine setting double-screw bolt 270, it is the millimeter level to adjust the precision. The guide post 280 penetrates through the guide unthreaded hole and is installed in the mounting base 240, and the guide post 280 plays a role in guiding and can limit the rotation of the positioning baffle 230 when the fine adjustment stud 270 rotates.

Also, in order to adapt to various types and series of railway wagons, in the side column production line of the railway wagon provided by the embodiment, the coarse adjustment of the position of the positioning baffle 230 in the transportation direction is realized by improving the connection structure between the supporting frame 210 and the rack 110 of the positioning section D. Referring specifically to fig. 5, the supporting frame 210 is connected to the frame 110 of the anti-toppling roller conveyor 100D of the positioning section D through the threaded fastener 260, along the conveying direction of the anti-toppling roller conveyor 100, a mounting groove or more than 2 mounting holes for mounting the threaded fastener 260 are formed in the frame 110, the position of the positioning baffle 230 can be changed greatly by changing the mounting position of the threaded fastener 260 in the mounting groove or mounting the threaded fastener 260 in different mounting holes, the coarse adjustment precision is in centimeter level, and the position a and the position b in fig. 4 respectively show two different mounting positions of the positioning assembly 200.

In this embodiment, the mounting seat 240 is not only used for fine adjustment of the position of the positioning baffle 230, but also used for guiding the lifting operation by the mounting seat 240. Referring to fig. 5, the inner side surface of the supporting frame 210 is provided with a sliding groove 250, and at least one side of the mounting seat 240 slidably extends into the sliding groove 250. The sliding grooves 250 may be groove structures directly formed on the inner side surface of the support frame 210, or may be independent groove structures welded or bolted to the inner side surface of the support frame 210, in order to ensure stress balance, preferably, 2 sliding grooves 250 are formed on the inner side surface of the support frame 210, and two sides of the mounting base 240 respectively slide and extend into the corresponding sliding grooves 250.

Considering that the weight of the side pillar 500 is large, the inertial impact force on the positioning baffle 230 is also large, and the impact force may cause the assembling clearance between the mounting seat 240 and the chute 250 to change, the chute 250 to deform, and the like after a long time of use. In order to reduce the influence of the impact force of the side pillar 500 on the sliding groove 250, in this embodiment, an included angle α is formed between the axis of the sliding groove 250 and the vertical direction, and the included angle α is 5 ° to 10 °, for example, 5 °, 6 °, 7 °, 8 °, 9 °, 10 °, and the like, so that only a part of component force in a large impact force can affect the sliding groove 250, and the service life of the device is further prolonged.

Because the height dimension of the side column 500 required by different types and different series of railway wagons is different, in order to adapt to various types and series of railway wagons, in the railway wagon side column production line provided by the embodiment, the support frame 210 of the positioning assembly 200 specifically adopts a door-shaped frame, the bottom surface of the cross beam 211 of the door-shaped frame is provided with the inverted limiting bolt 290, the limiting bolt 290 is positioned above the mounting seat 240, and the head of the limiting bolt 290 is coplanar with the sliding groove 250, so that the mounting seat 240 can touch the head of the limiting bolt 290 in the process of ascending along the sliding groove 250, and the limiting is realized. By adjusting the extension of the limit bolt 290 relative to the gantry beam 211, the maximum lift stroke of the mount 240 can be changed to meet the height requirements of different jambs 500.

As described above, the polishing and painting section E is used for performing inner cavity polishing of anti-rust paint and/or polishing of burrs on the end surface of the side pillar 500, so that the tool for polishing and painting section E only includes the anti-toppling rollgang 100 located at the station, and the anti-toppling rollgang 100 is used for transferring the side pillar 500 on one hand and can also serve as an operation platform for polishing and painting on the other hand. Because the opening of the clamping groove 133 of the anti-toppling conveying roller way 100 faces upwards, when the side column 500 is conveyed, the side column 500 can be placed in the clamping groove 133 in the mode that the inner cavity faces upwards, the clamping groove 133 stabilizes the clamping side column 500, the side column 500 is prevented from toppling in the conveying process, and therefore an operator can conveniently polish end face burrs and brush antirust paint in the inner cavity, and the manual face-turning and manual operation of righting the side column 500 is saved.

As mentioned above, the stacking section F is used for stacking and stacking the side posts 500, and stacking the side posts 500 may be performed manually or automatically by using a machine, which is used in this embodiment.
