Description

Technical Field

[0001] The present invention relates to the technical field of special steel round bar processing, and in particular to an intelligent special steel round bar sample rough processing system and method. Background Art

[0002] In modern steel companies, physical and mechanical property testing requires processing incoming special steel round bar specimens to produce specimens at specific sampling locations and sizes according to standards. The special steel round bar specimens undergo rough machining, sawing twice to obtain rough material for impact, tensile, and end-quenching tests, before undergoing the next step of fine machining.

[0003] The existing processing technology mainly relies on manual rough processing. The round bar sample is manually hoisted onto the manual sawing machine fixture through manual lifting equipment, the sample size is manually checked, and the sample is marked with a marking machine. It is placed on the fixture in a vertical or horizontal manner according to the required sawing position. Since the round bar sample has the phenomenon that the upper and lower end faces of the cylinder are not parallel, it needs to be leveled and clamped with pads. Even so, due to the use of pads for leveling and manual visual control of the sawing direction and the selection of pads, the sample cutting error is large. After the rough processing is completed, the sample needs to be manually placed on the corresponding transfer trolley. Since the sample is heavy, it brings great difficulties to transportation. In summary, the main problems are that the weight of the sample adds a burden to the manual labor, the clamping with pads is unstable, and the upper and lower end faces of the sample are not parallel and cannot be automatically clamped. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent special steel round bar sample rough processing system and method for realizing fully automatic sampling of round bar impact, stretching and end quenching blank samples, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent special steel round bar specimen rough processing system, comprising:

[0007] Automatic sawing module with special tooling for rough processing of round bar specimens;

[0008] A manipulator module with special grippers for loading, unloading and transporting round bar specimens;

[0009] The sample processing workbench module is used to process round bar samples. The workbench is equipped with an automatic sawing module, a manipulator module, a laser ranging module and a laser coding module.

[0010] The loading module is used to load and place round bar specimens;

[0011] Unloading module, used to store samples after rough processing;

[0012] The system operation interface is located outside the workbench and is used to control and debug the operating status of the entire system;

[0013] An alarm is provided on the system operation interface. When the sawing machine fails or an alarm appears on the system operation interface, the alarm is used to emit an audible and visual alarm.

[0014] Signal control line is used to transmit control signals and data between various components of intelligent special steel round bar specimens.

[0015] Furthermore, both the loading module and the unloading module are provided with material positions for placing sample slides, which are used to place round rod samples of different diameters, and the unloading module is adjacent to the loading module and is arranged within the physical working range of the manipulator module with special clamps.

[0016] Furthermore, the sample processing workbench module is surrounded by a protective device, which includes a safety fence. The safety fence contains a safety door lock. The safety door lock is connected to the system operation interface through a signal control line. When the system is running, the safety door lock is opened and an emergency stop is performed through the system operation interface.

[0017] Furthermore, the manipulator module consists of a clamp, a No. 1 calibrating cylinder clamp, a No. 2 calibrating cylinder clamp, a calibrating cylinder and an energized electromagnet; the clamp is arc-shaped, and is divided into three gear ranges of 90-150mm, 150-210mm and 210-280mm according to the different size ranges of the round rod specimens, and is respectively equipped with three sets of clamps for contacting round rod specimens of different sizes; the energized electromagnet is controlled by the system operation interface through a signal control line, and the lower part of the energized electromagnet is mechanically connected to the clamp; the No. 1 calibrating cylinder clamp and the No. 2 calibrating cylinder clamp are located on both sides of the clamp, and are controlled by the calibrating cylinder for regulation.

[0018] Furthermore, the automatic sawing module includes a fixed jaw, a movable jaw and a movable jaw cylinder. The jaws of the automatic sawing module are provided with a three-stage fixing method. Eight nitrogen springs are provided on the fixed jaw and the movable jaw, located on both sides of the sampling position of 30mm. The movable jaw is mechanically connected to the movable jaw cylinder. The spacing of the movable jaw clamping the round rod sample is adjusted by the movable jaw cylinder. A sample holder is provided under the round rod sample.

[0019] The present invention provides another technical solution: a processing method of an intelligent special steel round bar sample rough processing system, comprising the following steps:

[0020] S1: After the special steel round bar sample is loaded into the loading module, the diameter of the round bar is measured by the laser ranging module. After the diameter is compared with the sample information in the system operation interface, rough processing is performed. If the comparison is inconsistent, the alarm will flash and prompt manual processing;

[0021] S2: The round bar sample is transferred to the laser coding module by a robot module equipped with a special gripper, and the laser information of the two material head positions and one finished product position are marked;

[0022] S3: The round bar sample is transferred to the sample holder in the automatic sawing module by a manipulator module equipped with a special clamping jaw. The movable jaw is moved toward the fixed jaw by regulating the working of the movable jaw cylinder to clamp the round bar sample. The nitrogen spring ensures stable clamping.

[0023] S4: After sawing once vertically along the first chord of the round bar sample according to the standard, the sample processing workbench module is automatically moved 30mm, and then sawed vertically a second time along the direction of the other chord to obtain tensile specimens, impact specimens and end quenching specimens, which are then transferred to other machine tools for fine processing;

[0024] S5: After sawing, the cut blank is sucked by a robot module with a special clamp, and the material head is fixed by the cylinder clamps on both sides so that it is adsorbed by the energized electromagnet and placed on the arc surface at the same time. The sawn round steel is placed on the blanking module as a whole and then manually transferred to the next process.

[0025] Furthermore, the sample information in the system operation interface in S1 is obtained through reservation, specifically:

[0026] a: Read directly from the information system; b: Read by scanning the reserved interface; c: Manual input search; Among them, the system operation interface has an independent application that can save data and fault records, including the test number, processing time, and success or failure of each sample.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The processing method of the intelligent special steel round bar sample rough processing system of the present invention is as follows: the special steel round bar sample is loaded to the loading position, measured and compared with the sample information by a laser ranging module, and transferred to the sample holder by a manipulator module with special clamping jaws, and placed horizontally. The nitrogen spring contacts and clamps the sample, and then the movable jaw moves to the fixed jaw to clamp the round bar sample to ensure stable clamping. After the clamping is stable, the sample is sawed twice as required by the automatic sawing module, and transferred to the unloading position to prepare for subsequent processing, which solves the problem of inconvenient clamping of the special steel round bar sample during rough processing. At the same time, the automatic intelligent sawing method is adopted, which greatly improves the rough processing efficiency while reducing the labor intensity and improving the rough processing accuracy. The overall structure is scientific and reasonable, the operation is stable, and the failure rate is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The automatic sawing module 1 with a special tool is used for rough processing of round bar specimens. By placing the round bar specimen horizontally, since the cross section of the round bar specimen is in contact with the plane when it is placed horizontally, the interference caused by the non-parallel upper and lower end surfaces of the specimen when it is placed vertically is avoided. With the special tool, even if the upper and lower end surfaces of the round bar specimen are not parallel, it can still be stably clamped;

[0039] A manipulator module 8 with dedicated grippers is used for loading, unloading, and transporting round bar specimens. The manipulator module 8 includes an energized electromagnet 14 and a calibrating cylinder 13. Multiple energized electromagnets 14 attract round bar specimens when energized. Different electromagnet clamps are manually installed according to different diameters. Since the electromagnets alone clamp the specimen, force analysis indicates that a vertical lifting suction force and an external horizontal force are generated on the specimen. The calibrating cylinder 13 ensures stable clamping of the three specimen sections after the specimen is sawn into three.

[0040] The sample processing workbench module 25 is used to process round rod samples. The automatic sawing module 1, the manipulator module 8, the laser ranging module 22 and the laser coding module are installed on the workbench accordingly.

The jaws of the automatic sawing module 1 are provided with a three-stage fixing method. Eight nitrogen springs 15 are provided on the fixed jaw 16 and the movable jaw 17, which are located on both sides of the sampling position of 30 mm. This clamp can ensure that the end surfaces of both sides of the material are not aligned and can still be effectively clamped and can prevent waste from dumping. The movable jaw 17 is mechanically connected to the movable jaw cylinder 18. The movable jaw cylinder 18 is used to adjust the spacing of the movable jaw 17 for clamping the round rod sample. A sample holder 19 is provided below the round rod sample.

[0049] In summary, an embodiment of the present invention provides an intelligent special steel round bar sample rough processing system, in which the automatic sawing module 1 is used for automatically sawing samples, and the sawing method adopted is band sawing; the manipulator module 8 with special clamping claws is used to transport, load and unload samples according to the instructions contained in the system operation interface 4; the system operation interface 4 is used to display and input the system reserved sample information, to save data and fault records, to display the test number, processing time, success or failure of each sample, and to display the real-time animation of the sample processing, and has a pause function.
