Description
Technical Field
[0001] The present invention relates to the technical field of stainless steel product processing equipment, and specifically relates to a drying treatment device for pickling processing. Background Art
[0002] Pickling is a method for cleaning the metal surface. Generally, metal parts are immersed in an acid solution to remove thin films such as metal surface oxides. During the processing of stainless steel pipes, it is usually necessary to pickle the stainless steel pipes, and after pickling, the surface of the stainless steel pipes is dried. During the drying process of the stainless steel pipes, drying equipment such as hot air blowers is usually used to dry the outer wall and the inner wall of the pipes. Since the drying end position of the drying equipment is fixed and the drying range is limited, when batch drying multiple stainless steel pipes, the drying range for the pipes is often not comprehensive enough. There is a problem that a certain side of the pipe cannot face the drying equipment directly for drying, resulting in drying dead corners. And during the drying process of the pipes, special clamping equipment is required to clamp the pipes for feeding before drying and transferring after drying. However, if the outer wall of the pipe is clamped, the clamped surface of the outer wall of the pipe is blocked by the clamping equipment. If the inner wall of the pipe is clamped, the clamped surface of the inner wall of the pipe is blocked by the clamping equipment. No matter which clamping method is used, there is a situation where the clamped area cannot be dried by the drying equipment. Considering the above situation, there are problems of poor drying effect and insufficient drying range for stainless steel pipes. There is a lack of a device that can dry the outer wall and the inner wall of stainless steel pipes in all directions during batch drying of stainless steel pipes, and can switch the position of the clamped end of the pipe in real time according to the area of the current pipe being dried during the drying process to avoid drying dead corners, thereby improving the drying effect and drying efficiency.

[0011] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, the drying process of the pipe is divided into two stages. In the first stage, the pipe is in a vertical state and the inner wall of the pipe is clamped. At this time, the outer wall of the pipe is not blocked by the clamping device. The control driving rotation assembly is operated to drive the vertically placed pipe to perform circular motion around the axis of the driving rotation assembly, and the pipe itself synchronously performs slow circular motion during the movement, so as to realize the all-round drying operation of the outer surface of the stainless steel pipe. When the vertically placed stainless steel pipe is about to approach the position of the switching part, it enters the second stage of the drying operation. As the stainless steel pipe moves, with the cooperation of the conversion assembly, the switching part and the angle switching assembly, the clamped stainless steel pipe is also switched from the vertical state to the horizontal state, and with the cooperation of the clamping device, the clamping of the inner wall of the pipe is released and the outer wall of the pipe is clamped, so as to facilitate the hot air flow to pass through the inner side wall of the stainless steel pipe to dry its inner wall, and the rotation transmission assembly ensures that the stainless steel pipe itself performs circular motion, thus realizing a more comprehensive drying operation. The stainless steel pipe rotates through the first half circle by the driving rotation assembly for the drying work of the outer wall of the stainless steel pipe, and the stainless steel pipe rotates through the remaining half circle by the driving rotation assembly for the drying work of the inner wall of the stainless steel pipe, and rotates one full circle as a whole, thus completing the all-round and dead-angle-free drying treatment of the inner and outer walls of the stainless steel pipe.
[0012] In the present invention, when it is necessary to clamp the stainless steel pipe, first place the stainless steel pipe vertically directly above the driving assembly. The clamping ends of the outer wall clamping assembly are respectively located outside the stainless steel pipe, and the clamping ends of the inner wall clamping assembly are respectively located inside the stainless steel pipe. First, the driving end of the driving assembly is used to control the clamping ends of the inner wall clamping assembly to abut against the inner wall of the pipe, so as to realize the fixing function of clamping the pipe through the inner wall of the pipe. At this time, the outer wall of the pipe is in an unobstructed state, so as to facilitate the dead-angle-free drying treatment work of the outer wall of the stainless steel pipe. When the drying of the outer wall of the pipe is completed, by controlling the movement of the driving end direction of the driving assembly, the clamping ends of the inner wall clamping assembly are driven to separate from the inner wall of the pipe, and the clamping ends of the outer wall clamping assembly move synchronously towards the direction close to the outer wall of the pipe until the outer wall of the stainless steel pipe is clamped and fixed. At this time, the inner wall of the pipe is in an unobstructed state, so as to facilitate the dead-angle-free drying treatment work of the inner wall of the stainless steel pipe. Through the cooperation of the above-mentioned components, it is realized that during the drying process, the clamped end position of the pipe can be switched in real time according to the currently dried area of the pipe, avoiding the problem of drying dead angles and improving the drying efficiency.

The two ends of the spring 237 are respectively connected to the side end of the upper part of the switching frame 231 and the side end of the switching plate 235; The rotation transmission assembly 24 includes a second rotating shaft 241. The second rotating shaft 241 vertically passes through the bearing sleeve 236 and is rotatably connected to the bearing sleeve 236. The second rotating shaft 241 is disposed at a 90-degree angle to the first rotating shaft 220. One end of the first rotating shaft 220 close to the second rotating shaft 241 is provided with a recess, and the bottom of the second rotating shaft 241 is provided with a protrusion. When the second rotating shaft 241 is horizontally disposed, the protrusion of the second rotating shaft 241 is engaged with the recess of the first rotating shaft 220. A first bevel gear 242 is disposed on the first rotating shaft 220, and a second bevel gear 243 is disposed on the second rotating shaft 241. The first bevel gear 242 is engaged with the second bevel gear 243; The conversion assembly 25 includes two second belt pulleys 251. One of the second belt pulleys 251 is disposed at the rotational connection of the first connecting rod 232 and the switching frame 231, and the other second belt pulley 251 is rotatably disposed at the side end of the driving frame 219 and the two second belt pulleys 251 are disposed in parallel. The second transmission belt 252 is sleeved on the two second belt pulleys 251. A third bevel gear 253 is disposed at the rotational connection of the second belt pulley 251 and the driving frame 219. The third bevel gear 253 is vertically disposed, and a fourth bevel gear 254 is horizontally disposed below the third bevel gear 253 and the fourth bevel gear 254 is rotatably connected to the side end of the driving frame 219. The third bevel gear 253 is engaged with the fourth bevel gear 254. The switching member 26 is disposed at one side end of the driving column 213. A plurality of teeth are equidistantly disposed on one side of the switching member 26, and the switching member 26 is pre-engaged with the fourth bevel gear 254; When it is necessary to dry the pipe in the clamped state, first start the drying equipment box 1. Hot air flow for drying the pipe is generated inside the drying equipment box 1. The drying process is divided into two stages. In the first stage, the pipe is in a vertical state and the inner wall of the pipe is clamped. At this time, the outer wall of the pipe is not blocked by the clamping device. Control the driving motor 216 to work to drive the driving frame 219 to slowly rotate around the outside of the driving column 213. The switching member 26 is located at the position where the driving frame 219 rotates half a circle around the driving column 213. As the driving frame 219 rotates, each driving rod 221 at the side end of the driving frame 219 moves accordingly. And during the movement, one end of the driving rod 221 slides along the driving groove 214. Under the action of the driving groove 214, the first rotating shaft 220 is driven to perform a slow circular motion. As the first rotating shaft 220 rotates, the first bevel gear 242 is driven to rotate, and then the second bevel gear 243 meshing with it is driven to rotate. The rotation of the second bevel gear 243 drives the second rotating shaft 241 to rotate, and then drives the stainless steel pipe in a vertical state connected to the second rotating shaft 241 to slowly move in the direction of the switching member 26 while performing a slow circular motion by itself, so as to realize the all-round drying operation of the outer surface of the stainless steel pipe; when the stainless steel pipe in a vertical state is about to approach the switching member 26, at this time, the second stage of the drying operation is entered. As the stainless steel pipe moves, the fourth bevel gear 254 at the side end of the switching frame 231 contacts and disengages from the teeth at the side end of the switching member 26. Then, under the transmission of the fourth bevel gear 254, the third bevel gear 253 is driven to rotate a certain angle. And under the transmission of the second pulley 251 and the second transmission belt 252, the first connecting rod 232 is driven to rotate counterclockwise by a certain angle. Under the action of the spring 237, the second connecting rod 233 rotates accordingly, so that the switching plate 235 is switched from a vertical state to a horizontal state, and the second rotating shaft 241 is switched from a vertical state to a horizontal state. And the convex part at the end of the second rotating shaft 241 is engaged with the concave part at the end of the first rotating shaft 220. The first bevel gear 242 and the second bevel gear 243 are disengaged from each other. At this time, the rotation of the first rotating shaft 220 can directly drive the second rotating shaft 241 to perform a slow circular motion. At this time, the stainless steel pipe in the clamped state also switches from a vertical state to a horizontal state, and under the cooperation of the clamping device, the clamping of the inner wall of the pipe is released and the outer wall of the pipe is clamped instead, so as to facilitate the hot air flow to pass through the inner side wall of the stainless steel pipe to dry its inner wall. And along with the circular motion of the stainless steel pipe itself, a more comprehensive drying operation is realized; in the first half of the stroke when the driving frame 219 rotates around the outside of the driving column 213, it is for the drying work of the outer wall of the stainless steel pipe. By rotating the driving frame 219, the remaining half of the stroke of the stainless steel pipe moving around the driving column 213 is for the drying work of the inner wall of the stainless steel pipe. It rotates around the driving column 213 for one week as a whole, and then completes the all-round and dead-angle-free drying treatment of the inner and outer walls of the stainless steel pipe.

The three clamping plates 326 in the outer wall clamping assembly 32 are respectively located on the outer side of the stainless steel pipe, and the three clamping plates 326 in the inner wall clamping assembly 33 are respectively located on the inner side of the stainless steel pipe. Control the output end of the electric push rod 312 to extend, driving the driving plate 325 in the outer wall clamping assembly 32 to move away from the mounting bracket 311. As the driving plate 325 moves, the third connecting rod 323 and the fourth connecting rod 324 deflect by a certain angle, causing the clamping surfaces of the three clamping plates 326 in the outer wall clamping assembly 32 to synchronously move away from the outer side of the stainless steel pipe. And as the output end of the electric push rod 312 moves, the driving plate 325 in the inner wall clamping assembly 33 moves synchronously, thereby driving the three clamping plates 326 in the inner wall clamping assembly 33 to move in the same direction as the three clamping plates 326 in the outer wall clamping assembly 32 until the clamping surfaces of the three clamping plates 326 in the inner wall clamping assembly 33 abut against the inner wall of the pipe, thereby realizing the function of clamping and fixing the pipe through the inner wall of the pipe. At this time, the outer wall of the pipe is in an unobstructed state, facilitating the dead-angle-free drying treatment of the outer wall of the stainless steel pipe; when the drying of the outer wall of the pipe is completed, control the output end of the electric push rod 312 to contract, driving the three clamping plates 326 in the inner wall clamping assembly 33 to disengage from the inner wall of the pipe, and the three clamping plates 326 in the outer wall clamping assembly 32 synchronously move towards the outer wall of the pipe until the outer wall of the stainless steel pipe is clamped and fixed. At this time, the inner wall of the pipe is in an unobstructed state, facilitating the dead-angle-free drying treatment of the inner wall of the stainless steel pipe; through the cooperation of the above-mentioned components, it is realized that during the drying process, the clamped end position of the pipe can be switched in real time according to the currently dried area of the pipe, avoiding the problem of drying dead angles and improving the drying efficiency.

A loading rack 5 is provided on one side of the loading manipulator 4, and a blanking chute 6 is provided on the other side of the loading manipulator 4. One ends of the blanking chute 6 and the loading rack 5 pass through the drying equipment box 1 and are located outside the drying equipment box 1. The height of the end of the blanking chute 6 located outside the drying equipment box 1 is lower than the height of the end of the blanking chute 6 located inside the drying equipment box 1. The height of the end of the loading rack 5 located outside the drying equipment box 1 is higher than the height of the end of the loading rack 5 located inside the drying equipment box 1; Through the provided loading rack 5, a number of stainless steel pipes can be loaded from the outside of the drying equipment box 1 to the inside of the drying equipment box 1, and then the stainless steel pipes are sequentially loaded to the corresponding pipe clamping devices 3 by the loading manipulator 4 for clamping work. And when each stainless steel pipe is dried, it will be transferred to directly above the unloading chute 6 by the rotation of the driving frame 219. With the cooperation of the pipe clamping device 3, the clamping of the stainless steel pipe is released, and it falls on the unloading chute 6 and slides out to the outside of the drying equipment box 1, so as to facilitate on-site personnel to take it.
