Description

Technical Field

[0001] The invention relates to the field of stainless steel pipe processing, and in particular to a stainless steel pipe processing production device and method. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, etc. In the process of stainless steel pipe processing, sometimes it is necessary to cut the long stainless steel pipe into sections to facilitate the subsequent transportation and processing of the cut stainless steel pipe;

[0003] Application number CN201911379754.1 discloses a corrosion-resistant heterogeneous stainless steel pipe production device, including a base, a first clamping mechanism is fixedly installed on the base, and a second clamping mechanism is also adjustably installed on the base through a second horizontal adjustment component;

[0004] During the process of cutting the stainless steel pipe, the above patented structure can only cut one steel pipe at a time, which has low efficiency. When the cutting blade cuts the stainless steel pipe, it completes the cutting by approaching the stainless steel pipe. After cutting a part of the stainless steel pipe, the cutting blade needs to move away from the stainless steel pipe first, and then the stainless steel pipe moves forward a certain distance, and then the cutting blade approaches the stainless steel pipe to complete the cutting. The cutting cycle is repeated in this way. Therefore, the cutting blade does not do work in the process of moving away from the stainless steel pipe, which further reduces the efficiency of the cutting process of the stainless steel pipe.

[0018] A method for using a stainless steel pipe processing and production device comprises the following steps:

[0019] In the first step, a group of inner steel pipes are passed through the through hole in the middle of one side of the conveying box, and the inner steel pipes can be supported by the support guide rollers after entering the conveying box. Similarly, three groups of outer steel pipes are passed through the through holes on the outside of one side of the conveying box respectively, and the outer steel pipes can be supported by the support guide rollers after entering the conveying box, so that the inner steel pipes and outer steel pipes of the same material and specification can be subsequently conveyed to the inside of the cutting box and cut;

[0020] The second step is to support the inner steel pipe and the outer steel pipe respectively through the support guide rollers arranged inside the conveying box, and then start the conveying motor to drive the inner bevel gear and the inner conveying eccentric wheel to rotate respectively through the inner conveying disk, and the inner bevel gear can mesh with the outer bevel gear, so that the outer conveying disk can drive the outer conveying eccentric wheel to rotate. When the three groups of inner conveying eccentric wheels contact the inner steel pipe, the inner steel pipe can be conveyed to the right, and the outer steel pipe remains stationary at this time. When the outer conveying eccentric wheel contacts the outer steel pipe, the outer steel pipe can be conveyed to the right, and the inner steel pipe remains stationary at this time. Therefore, the inner steel pipe and the outer steel pipe can be intermittently conveyed to the right in an alternating manner, so that the positions where the inner steel pipe and the outer steel pipe are to be cut are conveyed to the inside of the cutting box;

[0021] The third step is, after the positions of the inner steel pipe and the outer steel pipe to be cut are transported to the inside of the cutting box, the cutting motor is started to drive the cutting saw blade to rotate through the rotating shaft, and then the electric rod is started to make the inner slider drive the inner cutting saw blade close to the inner steel pipe. At this time, the cutting saw blade is away from the outer steel pipe, and the outer steel pipe moves to the right. Therefore, the surface of the inner steel pipe moving to the right can be partially cut first. Similarly, when the inner steel pipe is cut, the electric rod makes the inner slider drive the outer cutting saw blade close to the outer steel pipe. At this time, the cutting saw blade is away from the inner steel pipe, and the inner steel pipe moves to the right. Then, the surface of the outer steel pipe moving to the right is partially cut. Therefore, the steel pipe can be cut in the process of the cutting saw blade moving inward or outward;

[0022] The fourth step, after the surfaces of the inner steel pipe and the outer steel pipe are partially cut, start the motor arranged on the middle part of the rotating bracket to drive one group of inner rotating disks to rotate, and the inner rotating disk can drive the inner rotating eccentric wheel to rotate, and the inner rotating disk can drive the other two groups of inner rotating disks to rotate at the same speed through the inner linkage disk and the inner rotating belt, and the inner rotating disk can drive the outer rotating disk to rotate through the outer linkage disk and the outer rotating belt, and the outer rotating disk can drive the outer rotating eccentric wheel to rotate, and when the inner rotating eccentric wheel contacts the inner steel pipe, it can drive the inner steel pipe to rotate, so that the uncut position on the surface of the inner steel pipe is aligned with the cutting saw blade, and then the cutting saw blade moves inward to cut the inner steel pipe, and similarly, when the outer rotating eccentric wheel contacts the outer steel pipe, it can drive the outer steel pipe to rotate, so that the uncut position on the surface of the outer steel pipe is aligned with the cutting saw blade, and then the cutting saw blade moves outward to cut the outer steel pipe.

[0023] (III) Beneficial effects

[0024] The present invention provides a stainless steel pipe processing and production equipment and method, which has the following beneficial effects:

[0025] 1. When the part of the inner conveying eccentric wheel protruding from the inner conveying disk contacts the inner steel pipe, the inner steel pipe can be moved to the right for conveying. When the part of the inner conveying eccentric wheel protruding from the inner conveying disk and the part of the outer conveying eccentric wheel protruding from the outer conveying disk contact the outer steel pipe, the outer steel pipe can be moved to the right for conveying. Therefore, the inner steel pipe and the outer steel pipe can be intermittently and alternately moved to the right for conveying.

[0026] 2. When the positions to be cut of the inner and outer steel pipes enter the interior of the cutting box, the electric rods at different positions drive the three sets of cutting saw blades to approach the inner steel pipe at the same time through the inner slider, and cut three different positions on the surface of the inner steel pipe at the same time. Similarly, the electric rod drives the inner slider to drive the outer cutting saw blade to approach the outer steel pipe, so that the steel pipe can be cut when the cutting saw blade moves inward or outward.

[0027] 3. After cutting the inner steel pipe or the outer steel pipe at three different positions on the surface, when the part of the inner rotating eccentric wheel protruding from the inner rotating disk contacts the inner steel pipe, it can drive the inner steel pipe to rotate, and the three uncut places on the surface of the inner steel pipe are rotated to the position of the cutting saw blade, so the inner steel pipe can be cut and segmented again by the cutting saw blade. Similarly, when the part of the inner rotating eccentric wheel protruding from the inner rotating disk and the part of the outer rotating eccentric wheel protruding from the outer rotating disk contact the outer steel pipe, it can drive the outer steel pipe to rotate, and the three uncut places on the surface of the outer steel pipe are rotated to the position of the cutting saw blade, so the outer steel pipe can be cut and segmented again by the cutting saw blade.

Therefore, the inner steel pipe 6 and the outer steel pipe 7 can be intermittently conveyed to the right in an alternating manner, so that the positions to be cut of the inner steel pipe 6 and the outer steel pipe 7 are conveyed to the inside of the cutting box 1;

[0062] The third step is, after the positions of the inner steel pipe 6 and the outer steel pipe 7 to be cut are transported to the inside of the cutting box 1, the cutting motor 107 is started to drive the cutting saw blade 109 to rotate through the rotating shaft 108, and then the electric rod 105 is started to make the inner slider 106 drive the inner cutting saw blade 109 close to the inner steel pipe 6. At this time, the cutting saw blade 109 is away from the outer steel pipe 7, and the outer steel pipe 7 moves to the right. Therefore, the surface of the inner steel pipe 6 moving to the right can be partially cut first. Similarly, after the inner steel pipe 6 is cut, the electric rod 105 makes the inner slider 106 drive the outer cutting saw blade 109 close to the outer steel pipe 7. At this time, the cutting saw blade 109 is away from the inner steel pipe 6, and the inner steel pipe 6 moves to the right. Then, the surface of the outer steel pipe 7 moving to the right is partially cut. Therefore, the steel pipe can be cut in the process of the cutting saw blade 109 moving inward or outward;

[0063] In the fourth step, after the surface of the inner steel tube 6 and the outer steel tube 7 are partially cut, the motor arranged in the middle of the rotating bracket 301 is started to drive one group of inner rotating disks 303 to rotate, and the inner rotating disk 303 can drive the inner rotating eccentric wheel 304 to rotate, and the inner rotating disk 303 can drive the other two groups of inner rotating disks 303 to rotate at the same speed through the inner linkage disk 305 and the inner rotating belt 309, and the inner rotating disk 303 can drive the outer rotating disk 307 to rotate through the outer linkage disk 306 and the outer rotating belt 310, and the outer rotating disk 307 can drive The outer rotating eccentric wheel 308 rotates, and when the inner rotating eccentric wheel 304 contacts the inner steel pipe 6, it can drive the inner steel pipe 6 to rotate, so that the uncut position on the surface of the inner steel pipe 6 is aligned with the cutting saw blade 109, and then the cutting saw blade 109 moves inward to cut the inner steel pipe 6. Similarly, when the outer rotating eccentric wheel 308 contacts the outer steel pipe 7, it can drive the outer steel pipe 7 to rotate, so that the uncut position on the surface of the outer steel pipe 7 is aligned with the cutting saw blade 109, and then the cutting saw blade 109 moves outward to cut the outer steel pipe 7.

[0064] The working principle and use process of the present invention are as follows: by inserting a group of inner steel pipes 6 from the through hole 5 in the middle of the conveying box 2 into the interior of the rotating box 3, and inserting three groups of outer steel pipes 7 from the through hole 5 on the outside of the conveying box 2 into the interior of the rotating box 3, the inner steel pipes 6 and the outer steel pipes 7 can be placed on the support guide rollers 302 arranged inside the conveying box 2 and the rotating box 3 and supported, and then the conveying motor 202 is started to drive the inner bevel gear 204 and the inner conveying eccentric wheel 205 to rotate through the inner conveying disk 203, and the outer conveying disk 206 can drive the outer conveying eccentric wheel 208 to rotate through the meshing between the inner bevel gear 204 and the outer bevel gear 207, and when the part of the inner conveying eccentric wheel 205 protruding from the inner conveying disk 203 contacts the inner steel pipe 6, the inner steel pipe 6 can be moved to the right During the transportation, the portion of the inner conveying eccentric wheel 205 protruding from the inner conveying disc 203 and the portion of the outer conveying eccentric wheel 208 protruding from the outer conveying disc 206 do not contact the outer steel pipe 7, so that the outer steel pipe 7 remains stationary, while the inner steel pipe 6 moves to the right. Similarly, when the portion of the inner conveying eccentric wheel 205 protruding from the inner conveying disc 203 and the portion of the outer conveying eccentric wheel 208 protruding from the outer conveying disc 206 contact the outer steel pipe 7, the outer steel pipe 7 can be moved to the right for transportation. During the transportation, the portion of the inner conveying eccentric wheel 205 protruding from the inner conveying disc 203 and the portion of the outer conveying eccentric wheel 208 protruding from the outer conveying disc 206 do not contact the inner steel pipe 6, so that the inner steel pipe 6 remains stationary, while the outer steel pipe 7 moves to the right. The outer steel pipe 7 is intermittently and staggeredly moved to the right for transportation. When the positions to be cut of the inner steel pipe 6 and the outer steel pipe 7 enter the interior of the cutting box 1, that is, the cutting positions of the inner steel pipe 6 and the outer steel pipe 7 move to the cutting saw blade 109, the electric rod 105 and the cutting motor 107 are started again. The cutting motor 107 drives the cutting saw blade 109 to rotate through the rotating shaft 108, and the electric rods 105 at different positions drive the three groups of cutting saw blades 109 to approach the inner steel pipe 6 at the same time through the inner slider 106, and cut three different positions on the surface of the inner steel pipe 6 at the same time. At this time, the cutting saw blade 109 is away from the outer steel pipe 7, so the three different positions on the surface of the inner steel pipe 6 can be cut first. Similarly, when the inner steel pipe 6 is cut, the electric rod 105 causes the inner slider 106 to drive the outer The cutting saw blade 109 is close to the outer steel pipe 7, and at this time the cutting saw blade 109 is away from the inner steel pipe 6, and then the surface of the outer steel pipe 7 is cut at three different positions. Therefore, when the cutting saw blade 109 moves inward or outward, the steel pipe can be cut, and the three groups of cutting saw blades 109 do not contact and interfere with each other. In the process of the cutting saw blade 109 moving inward or outward, the driving teeth 110 and the single-sided toothed belt 114 can make the inner cutting saw blade 109 rotate in the same direction and at the same speed, and the driven teeth 113 and the double-sided toothed belt 115 can make the outer cutting saw blade 109 rotate in the same direction and at the same speed, and in the process of the inner slider 106 driving the cutting saw blade 109 and the driving teeth 110 to move, the driven teeth 113 can drive the spring 112 to deform through the outer slider 111.Through the deformation of the spring 112, the driven tooth 113 can always keep the single-sided toothed belt 114 and the double-sided toothed belt 115 in a tensioned state. At the same time, after cutting the inner steel tube 6 or the outer steel tube 7 at three different positions on the surface, the inner steel tube 6 or the outer steel tube 7 does not move to the right first, and at the same time, the motor set on the rotating bracket 301 is started to drive a group of inner rotating disks 303 to rotate, and the inner rotating disk 303 can simultaneously drive the inner rotating disks 303 at other positions to rotate through the inner linkage disk 305 and the inner rotating belt 309, and through the outer linkage disk 306 and The outer rotating belt 310 can drive the outer rotating disk 307 at different positions to rotate. When the portion of the inner rotating eccentric wheel 304 protruding from the inner rotating disk 303 contacts the inner steel pipe 6, it can drive the inner steel pipe 6 to rotate and make the three uncut places on the surface of the inner steel pipe 6 rotate to the position of the cutting saw blade 109. Therefore, the inner steel pipe 6 can be cut again by the cutting saw blade 109, and the inner steel pipe 6 moves to the right after the cutting is completed. In this process, the portion of the inner rotating eccentric wheel 304 protruding from the inner rotating disk 303 and the outer rotating eccentric wheel 308 The portion protruding from the outer rotating disk 307 does not contact the outer steel tube 7, so that the outer steel tube 7 remains stationary. Similarly, when the portion of the inner rotating eccentric wheel 304 protruding from the inner rotating disk 303 and the portion of the outer rotating eccentric wheel 308 protruding from the outer rotating disk 307 contact the outer steel tube 7, the outer steel tube 7 can be driven to rotate, and the three uncut places on the surface of the outer steel tube 7 are rotated to the position of the cutting saw blade 109, so that the outer steel tube 7 can be cut again by the cutting saw blade 109, and the outer steel tube 7 moves to the right after cutting. In this process, The portion of the inner rotating eccentric wheel 304 protruding from the inner rotating disk 303 does not contact the inner steel pipe 6, so that the inner steel pipe 6 remains stationary. After the inner steel pipe 6 or the outer steel pipe 7 is cut at one place, the inner steel pipe 6 or the outer steel pipe 7 can be transported to the right again, and the surface portion of the inner steel pipe 6 or the outer steel pipe 7 at another place can be cut again, and then the inner steel pipe 6 or the outer steel pipe 7 can be rotated, and the uncut surface portion of the inner steel pipe 6 or the outer steel pipe 7 can be cut again, so that multiple groups of inner steel pipes 6 or outer steel pipes 7 can be cut at the same time, thereby improving the cutting efficiency of the steel pipe.
