Description

Technical Field

[0001] The invention relates to the technical field of pipe surface treatment equipment, in particular to a pickling device for stainless steel pipes and a use method thereof. Background Art

[0002] In the production of stainless steel pipe fittings, it is necessary to passivate the initially formed pipe fittings. The previous step of passivation is pickling. One of the purposes of pickling is to create conditions for passivation treatment and ensure the formation of a good passivation film, because pickling causes an average of 10um thick layer of the stainless steel surface to be corroded away. The chemical activity of the acid makes the dissolution rate of the defective parts higher than other parts on the surface. Therefore, pickling can make the entire surface tend to be evenly balanced and remove some hidden dangers that were originally prone to corrosion. During pickling, the stainless steel pipe fittings are generally placed in the pickling tank and soaked for a period of time, and then taken out for cleaning. The operator needs to put in and take out manually or use tools. The degree of automation is low, and the labor intensity for the operator is high, and thus the surface treatment efficiency of the related pipe fittings is reduced. Summary of the invention

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0026] See also Figure 1-7 An embodiment of the present invention is as follows: a pickling device for stainless steel pipes, comprising a pickling tank 1; lifting members 2 are provided on both sides of the pickling tank 1; a synchronous plate 4 is also provided on the lifting member 2, and a plurality of supporting components 3 with the same structure are slidably mounted on the synchronous plate 4; the supporting component 3 comprises a supporting frame 30, and a partition 32 is also provided on the supporting frame 30, and the number of the partitions 32 is multiple and movably mounted on the supporting frame 30.

[0027] In summary, the synchronous plate 4 is lifted and lowered by the lifting member 2, so that the supporting assembly 3 installed on the synchronous plate 4 can be lifted and lowered in the pickling tank, so that the pipe fittings can be put into the pickling tank or taken out of the pickling tank without manual operation, thereby reducing the output of manpower and the damage caused to the operator by the pickling liquid;

[0028] At the same time, the support frame 30 can slide on the synchronous plate 4, so that the device can adapt to pipes of different lengths, thereby improving the application capability of the device.

[0029] In particular, due to the provision of the partition 32, the pipe fittings can be placed in layers to increase the number of pipe fittings during pickling. Based on this, the pipe fittings can automatically enter the pickling tank while the pipe fittings are pickled. In particular, the pipe fittings can be stacked in layers, which can not only increase the number of pipe fittings, but also improve the pickling efficiency of the pipe fittings.

[0030] In order to improve the stability of the support frame 30 after being connected to the synchronization plate 4, and thus improve the bearing capacity of the support frame 30, both ends of the support frame 30 are connected to the synchronization plate 4 through the provided connection parts 34.

[0031] Furthermore, since the synchronization plate 4 is also provided with a slide groove 7, and is connected to the connecting part 34 through a connecting piece 38 provided in the slide groove 7, the connecting piece 38 can be used to complete the connection between the synchronization plate 4 and the connecting part 34, so that the support frame 30 can slide stably and reliably on the synchronization plate 4.

[0032] Specifically, since the connecting member 38 includes a slider 36 that slides in the slide groove 7, and the slider 36 passes through the connecting portion 34 through the provided screw 35 and is connected to the provided fastener 33, the fastener 33 is loosened, and the slider 36 can slide along the slide groove 7 to complete the adjustment of the position of the support frame 30 on the synchronization plate 4; the fastener 33 is tightened to fix the support frame 30 on the synchronization plate 4 to complete the positioning of the support frame 30. The fastener 33 is a knob, and is connected to the screw 35 through the internal thread provided therein.

[0033] On the basis of the above scheme, the supporting assembly 3 also includes a support block 31, and the support block 31 is adaptively connected with the limiting groove 39 provided on the back side of the partition 32 through a limiting protrusion 311. Therefore, when the limiting protrusion 311 is inserted into the limiting groove 39, the limiting groove 39 and the limiting protrusion 311 can be used to cooperate with each other to prevent the partition 32 from sliding left and right on the support block 31, so as to ensure that the partition 32 can be stably and reliably located on the support block 31.

[0034] Furthermore, since a bolt 37 is provided on one side of the support frame 30, and the bolt 37 passes through the support frame 30 and then is threadedly matched with the internal threaded hole 310 provided on the support block 31. Therefore, the installation position of the support block 31 can be adjusted. Specifically, the through holes at different positions on the side of the support frame 30 can be connected with the internal threaded hole 310 by using the bolt 37, so that the position of the support block 31 can be adjusted. Since the position of the support block 31 can be adjusted, the spacing between two adjacent partitions 32 can be adjusted, and the spacing between the partition 32 and the bottom surface of the support frame 30 can also be adjusted, so that the device can adapt to pipes of different diameters.

[0035] Furthermore, since the partition 32 and the support frame 30 are both provided with a rack-shaped support portion 312 on the side facing the pipe fitting, the contact area between the support portion 312 and the outer wall of the pipe fitting can be reduced, so that while supporting the pipe fitting, the electrolyte can also be fully in contact with the outer wall of the pipe fitting to ensure the treatment quality of the outer wall of the pipe fitting.

[0036] In addition, a mounting plate 8 is also provided in the middle of the synchronous plate 4, and the working part of the lifting member 2 is movably connected to the mounting plate 8, thereby making the connection between the lifting member 2 and the synchronous plate 4 simple and convenient; specifically, the connection between the lifting member 2 and the mounting plate 8 can be achieved by passing a bolt through the working end of the lifting member 2 and connecting it to the threaded hole on the mounting plate 8.

[0037] In order to pour out the electrolyte inside the pipe fittings and reduce the electrolyte from being scattered in other places in the workshop as the pipe fittings move, the end surface of the pickling tank 1 is also provided with a driving member 5, and a cushion block 6 is provided on the driving member 5, and the driving member 5 causes the pipe fitting located on the cushion block 6 to be lifted upward. Therefore, when one end of the pipe fitting is placed on the cushion block 6, the driving member 5 causes the cushion block 6 to rise, and at this time, one end of the pipe fitting rises upward, and the other end is located on the support frame 30, so that the electrolyte inside the pipe fitting can flow out quickly.

[0038] Furthermore, since the cushion block 6 has an arc surface 9 on one side facing the pipe fitting, the damage to the pipe fitting caused by the cushion block 6 can be reduced. In actual use, an anti-skid rubber pad is also laid on the arc surface 9. The driving member 5 and the lifting member 2 are preferably hydraulic cylinders.

[0039] The present invention also discloses a method for using the above-mentioned equipment, namely: a method for using the pickling equipment for stainless steel pipes, which is specifically as follows: placing the pipe fittings on the bottom surface of the support frame 30, then installing the partition 32 on the support frame 30, and then placing the remaining pipe fittings on the partition 32; after the placement is completed, start the lifting member 2, and at this time the lifting member 2 moves downward to immerse the pipe fittings in the pickling tank 1; after the pickling is completed, the lifting member 2 moves upward to move the pipe fittings out of the pickling tank 1.

[0040] In summary, the automatic pickling of stainless steel pipe fittings does not require operators to put in or take out stainless steel pipe fittings, which reduces the labor intensity of operators and their contact with pickling liquid. The degree of automation is high and the operating risk is low. Stainless steel pipe fittings of different lengths and diameters can be pickled, and the scope of application is wide. The pickling liquid that has not flowed out of the inside of the stainless steel pipe fittings can be redirected into the pickling box to prevent the pickling liquid from leaking, further improving the safety of the operator's working environment.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
