Description

Technical Field

[0001] This utility model relates to the field of chassis panel manufacturing technology, and in particular to an acid pickling device for chassis panel manufacturing. Background Technology

[0002] Pickling is a method of removing oxide scale and rust from the surface of steel using acid solutions; it is a method of cleaning metal surfaces. Chassis panels require pickling during production. Because chassis panels are long, rectangular metal panels, current technologies mostly use a hoisting method, vertically placing the chassis panel into the pickling tank for pickling. However, due to their size, the lifting height is too large, which is very inconvenient. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides an acid pickling device for chassis panel production, which effectively solves the problem of inconvenient operation due to excessive lifting height during chassis panel pickling.

[0004] The technical solution to the technical problem is: a pickling device for chassis panel production, including a pickling tank, a cleaning tank arranged side by side on the side of the pickling tank, a hanging rail above the pickling tank, a hydraulic cylinder slidably installed on the hanging rail, a fixed plate at the bottom of the hydraulic cylinder, motors on both sides of the fixed plate, steel wires wound on the output shaft of the motors, and four buckles connected to the ends of the steel wires. The buckles are fixed at the four corners of the chassis panel to lift and lower the chassis panel.

[0005] Preferably, the pickling tank is provided with a conduit on its side, a pump is provided on the conduit, and pickling nozzles are provided inside the pickling tank.

[0006] Preferably, the cleaning pool is equipped with cleaning nozzles on both sides above, and the cleaning nozzles are connected to a water source.

[0007] Preferably, the motor is a dual-head motor, with winding wheels connected to both ends of the motor.

[0008] Preferably, the buckle includes a lower plate and an upper plate. The lower plate has an L-shaped structure and is provided with multiple first columnar protrusions. The upper plate is slidably connected to the lower plate. The bottom of the upper plate is provided with multiple second columnar protrusions opposite to the lower plate. The first columnar protrusions and the second columnar protrusions cooperate to clamp the chassis panel.

[0009] Preferably, the lower plate is provided with a sliding groove, and guide rods extend from both sides of the upper plate into the sliding groove. A spring is provided in the sliding groove, and the spring pushes the guide rod upward. The lower plate is provided with a first through hole, and the upper plate is provided with a second through hole at its end. The steel wire passes through the second through hole and then passes through the first through hole from the bottom of the lower plate and is fixedly connected to the upper plate.

[0010] This invention is simple, ingenious, and easy to use. It allows the chassis panel to be horizontally suspended and placed into the pickling tank for pickling, thereby reducing its lifting range and improving pickling efficiency. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 7 It is known that a pickling device for chassis panel production includes a pickling tank 1, a cleaning tank 2 arranged side by side on the side of the pickling tank 1, a hanging rail above the pickling tank 1, a hydraulic cylinder 3 slidably mounted on the hanging rail, a fixing plate 4 at the bottom of the hydraulic cylinder 3, motors 5 arranged on both sides of the fixing plate 4, a steel wire 6 wound on the output shaft of the motor 5, and a buckle connected to the end of the steel wire 6. Four buckles are provided and fixed to the four corners of the chassis panel to lift and lower the chassis panel.

[0020] In practical use, this utility model Secure the chassis panel with four clips and suspend it on the hanging rail. Move the hanging rail to move the chassis panel above the pickling tank 1. Motor 5 controls the steel wire 6 to extend synchronously and put the chassis panel into the pickling tank 1 for pickling. After pickling, lift the chassis panel into the cleaning tank 2 for rinsing with clean water, and then move the exterior to dry.

[0021] The chassis panel is pickled in a horizontal position, which has a short lifting distance and can be moved quickly. The entire chassis panel enters the pickling tank 1 at basically the same time, and the pickling time is controllable, which is conducive to controlling the pickling effect.

[0022] A pickling tank 1 is provided with a conduit 7 on its side, and a pump 8 is provided on the conduit 7. A pickling nozzle 9 is provided inside the pickling tank 1. The pump 8 can deliver the pickling liquid at the bottom of the pickling tank 1 to the pickling nozzle 9 through the conduit 7. A filter screen is provided inside the conduit 7 to improve the circulation efficiency of the pickling liquid and reduce the consumption of pickling liquid.

[0023] Cleaning nozzles 10 are installed on both sides of the upper part of the cleaning pool 2. The cleaning nozzles 10 are connected to a water source and use clean water to rinse the chassis panel. The cleaning pool 2 collects wastewater.

[0024] The motor 5 is a dual-head motor 5, with winding wheels 11 connected to both ends of the motor 5. The two winding wheels 11 rotate synchronously and lift one side of the chassis panel synchronously, so that the chassis panel can be tilted, making it easier for the pickling solution above to slide down and preventing the pickling solution from being carried out.

[0025] The buckle includes a lower plate 12 and an upper plate 13. The lower plate 12 has an L-shaped structure and multiple first columnar protrusions 14. The upper plate 13 is slidably connected to the lower plate 12. The bottom of the upper plate 13 has multiple second columnar protrusions 15 opposite to the lower plate 12. The first columnar protrusions 14 and the second columnar protrusions 15 cooperate to clamp the chassis panel. The lower plate 12 has a sliding groove 16. The upper plate 13 has guide rods 17 extending from both sides into the sliding groove 16. A spring 18 is installed in the sliding groove 16. The spring 18 pushes the guide rod 17 upward. The lower plate 12 has a first through hole 19. The upper plate 13 has a second through hole 20 at its end. The steel wire 6 passes through the second through hole 20 and then passes through the first through hole 19 from the bottom of the lower plate 12 and is fixedly connected to the upper plate 13.

[0026] When the buckle clamps the chassis panel, it inserts the chassis panel between the lower plate 12 and the upper plate 13. Under the action of gravity, the chassis panel moves downward toward the lower plate 12, which tightens the steel wire 6. The tightening of the steel wire 6 causes the upper plate 13 to move closer to the lower plate 12 within the slide groove 16. The first columnar protrusion 14 and the second columnar protrusion 15 work together to clamp the chassis panel. Due to the angle of the steel wire 6, an upward force is generated at the end of the upper plate 13, causing the upper plate 13 to tend to rotate around the guide rod 17. This causes the first columnar protrusion 14 of the upper plate 13 to rotate toward the lower plate 12, thus making the chassis panel more securely fixed in the buckle.

[0027] Compared with the prior art, this utility model has the following advantages: it changes the traditional vertical pickling to horizontal pickling, ensuring the consistency of pickling time and thus improving the pickling effect; the horizontal hoisting has a shorter lifting height and faster speed, which is conducive to operation.
