Description

Technical Field

[0001] The invention relates to the technical field of automatic conveying structures, in particular to a seamless steel pipe surface pickling device with an automatic conveying structure. Background Art

[0002] At present, the world's seamless steel pipe production processes mainly include hot-rolled seamless steel pipes and cold-drawn seamless steel pipes. Hot-rolled seamless steel pipes have high production efficiency and low energy consumption and are widely used. However, their disadvantages are poor geometric dimensional accuracy, and the production process of small-diameter seamless steel pipes produced by hot rolling is complex and costly. Therefore, high-precision small-diameter seamless steel pipes generally use cold drawing processes. In order to obtain seamless steel pipes with smaller size and better quality, cold rolling, cold drawing or a combination of the two methods must be used, that is, one end of the seamless steel pipe round tube embryo is first heated and perforated, and the tube embryo obtained after the heating and perforation treatment is sent to a reducing device for head reduction, and the next step is annealing and pickling. After the surface is oiled, it is cold drawn several times, and finally the tube embryo is straightened after heat treatment. After quality inspection, the finished seamless steel pipe can be obtained, in which pickling of the seamless steel pipe embryo is an indispensable processing technology, such as a continuous pickling device for seamless steel pipe and a pickling method thereof disclosed in Publication No. CN108085707B The method is characterized in that a plurality of liquid inlet holes are arranged on the surface of the pickling box, and the pickling liquid enters the pickling box through the liquid inlet holes for pickling, a switch plate is arranged on the side wall of the pickling box, and a latch for switching is arranged on the switch plate. The switch plate is opened to add or take out the tube embryo, and the latch is inserted to ensure that the tube embryo will not slip out of the pickling box during the pickling process; a permeable plate is arranged at the bottom of the spray tank, and the permeable plate is arranged at intervals with the bottom plate of the spray tank. The permeable plate is provided with a plurality of permeable holes penetrating from top to bottom. After the pickling liquid sprayed by the atomizing nozzle pickles the tube embryo, the pickling liquid flows into the permeable plate and flows to the bottom of the spray tank through the permeable holes to recover the pickling liquid, saving resources and not wasting, and the unified recovery and treatment of the pickling liquid reduces the cleaning and treatment of the surrounding sites by the operators; the pickling box and the permeable plate are made of metal material to avoid the pickling device from being seriously corroded due to the chemical properties of the pickling liquid and being unable to be used normally. Therefore, it can be seen that the existing surface pickling device of a seamless steel pipe has met people's use needs, but the following problems still exist.

[0003] In order to remove oxides on the surface of seamless steel pipes, pickling is generally performed by flushing. In order to ensure a better flushing effect of the seamless steel pipe, the operator is generally required to manually feed the material at intervals. However, this feeding method requires workers to work next to the machine for a long time, resulting in a waste of manpower, and workers need to frequently replace the seamless steel pipes being flushed, resulting in low overall work efficiency and reducing the practicality of the device. Therefore, a seamless steel pipe surface pickling device with an automatic conveying structure is urgently needed to solve the above-mentioned problems. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The seamless steel pipe surface pickling device with automatic conveying structure is provided with a supporting base, a placing plate, a fixed frame, an output motor, a first output shaft, a second output shaft, a pulley and a belt. The output motor is started to drive the first output shaft and the pulley to rotate, and the three sets of pulleys can be driven to rotate through the action of the belt, and the second output shaft can be driven to rotate through the pulley. At the same time, a first rotating disk, a first connecting rod, a second rotating disk, a second connecting rod, a lifting plate, a connecting plate, a third connecting rod and a seamless steel pipe placing cavity are provided. The two sets of first rotating disks can be driven to rotate through the action of the two sets of second output shafts. The first connecting rod, the second rotating disk, the second connecting rod and the lifting plate can be driven to rotate through the rotation of the first rotating disk, and the seamless pipe on the surface of the placing plate can be pushed forward through the lifting plate. At the same time, a baffle plate, a hinged rod, a fixed block, a second spring and a fixed plate are provided. When the lifting plate moves upward and abuts against the baffle plate, the baffle plate is driven to rotate through the rotating shaft, and through the action of the hinged rod , the fixed block can be pushed to move to the right, and the second spring is squeezed and deformed. At the same time, when the baffle rotates, a group of seamless pipes can be dropped from the seamless steel pipe placement cavity. When the jacking plate and the baffle are separated from the abutment, the elastic action of the second spring can drive the baffle to rotate in the opposite direction. At this time, the baffle can block the seamless pipe inside the seamless steel pipe placement cavity again. The above device solves the problem that in order to remove the oxide on the surface of the seamless steel pipe, pickling is generally performed by flushing. In order to ensure a better flushing effect of the seamless steel pipe, the operator is generally required to manually perform intermittent feeding. However, this feeding method requires workers to work at the machine for a long time, resulting in a waste of manpower, and the workers need to frequently replace the seamless steel pipes to be flushed, resulting in low overall work efficiency and reducing the practicality of the device. The device can automatically complete quantitative blanking and automatically complete intermittent feeding, reducing manpower loss, improving the working efficiency of the device, and further improving the practicality of the device.

[0015] Meanwhile, rollers, transmission grooves, sleeves, limit blocks, flushing nozzles, connecting pipes, and hoses are provided. The hoses are connected to the external water tank. When the first output shaft rotates, the rollers are driven to rotate. At this time, the limit blocks reciprocate back and forth in the transmission groove, which can drive the sleeves and the flushing nozzles to reciprocate back and forth. Through this mechanism, the device can fully flush the seamless steel pipes under the flushing nozzles, which greatly reduces the manpower consumption while ensuring the flushing effect of the seamless steel pipes. At the same time, in conjunction with the above-mentioned stepping mechanism, the device can automatically complete the cyclic process of quantitative blanking, automatic feeding and comprehensive flushing of the seamless steel pipes, and the two groups of mechanisms share a power source, which greatly improves the economic benefits of the device.

The device can automatically complete quantitative blanking and automatically complete intermittent feeding, which reduces manpower loss, improves the working efficiency of the device, and further improves the practicality of the device.

[0028] The right end of the placement plate 120 is fixedly connected with a guide plate 121, and the shape of the guide plate 121 is set to be inclined.

The end of the second slider 282 away from the second slide groove 281 is fixedly connected to the fixed block 330. The second slider 282 slides inside the second slide groove 281, thereby improving the stability of the fixed block 330 when moving left and right.

[0031] The right end of the baffle 310 is fixedly connected to a first spring 311 , and one end of the first spring 311 away from the baffle 310 is fixedly connected to the bottom end of the seamless steel pipe placement cavity 280 .

[0034] A first sliding groove 131 is provided at the top of the fixed frame 130, and a first slider 132 is slidably connected inside the first sliding groove 131. One end of the first slider 132 away from the first sliding groove 131 is fixedly connected to the sleeve 430. The first slider 132 slides inside the first sliding groove 131, thereby further improving the stability of the sleeve 430 when it moves back and forth.

[0035] Working principle: When the seamless pipe needs to be flushed, the hose 470 is connected to the external water tank, the output motor 140 is started, and the first output shaft 150 and the pulley 170 are driven to rotate. The three sets of pulleys 170 can be driven to rotate through the action of the belt 180, and the second output shaft 160 can be driven to rotate through the pulley 170. The two sets of second output shafts 160 can be driven to rotate. The first connecting rod 220, the second rotating disk 230, the second connecting rod 240 and the lifting plate 250 can be driven to rotate through the rotation of the first rotating disk 210. The seamless pipe on the surface of the placement plate 120 can be pushed forward by the lifting plate 250. When the lifting plate 250 moves upward and abuts against the baffle 310, the baffle 310 is driven to pass The shaft rotates, and the action of the hinge rod 320 can push the fixed block 330 to move to the right, and the second spring 340 is squeezed and deformed. At the same time, when the baffle 310 rotates, a group of seamless pipes can fall from the seamless steel pipe placement cavity 280. When the lifting plate 250 and the baffle 310 are out of contact, the elastic action of the second spring 340 can drive the baffle 310 to rotate in the opposite direction. At this time, the baffle 310 can block the seamless pipe inside the seamless steel pipe placement cavity 280 again. When the first output shaft 150 rotates, it can drive the roller 410 to rotate. At this time, the limit block 440 performs reciprocating motion back and forth in the transmission groove 420, which can drive the sleeve 430 and the flushing nozzle 450 to perform reciprocating motion back and forth, and the operation is completed.
