Technical Field
[0001] The utility model relates to the technical field of wire rod straightening, in particular to a double-station straightening machine suitable for small-sized wire rods. Background Art
[0002] When conducting tensile tests and upsetting tests on small-sized wire rods with a diameter of ≤ Φ26, according to the test requirements, it is not necessary to process them into standard specimens. Samples can be directly selected for testing after shearing the head and tail. However, since the wire rods are packaged and transported in a coiled manner, the samples will have a certain curvature after sampling and cannot be directly tested. Before the test, a straightening machine is required to straighten the samples. For mechanical tensile properties such as yield strength and elongation, the samples must be straight, otherwise the test results will deviate. During the upsetting test, if the upper and lower end faces of the sample are not perpendicular to the sample axis, it will also cause the tested sample to show abnormal morphology, affecting the result judgment. However, due to the great differences in strength, plasticity, and hardness of different materials for small-sized wire rods, different types of straightening machines need to be selected or the support bases of the straightening machine need to be continuously replaced according to the material of the sample during straightening, resulting in insufficient universality, time-consuming and laborious, and being unfavorable for improving the test efficiency.
[0003] Therefore, it is very necessary to invent a double-station straightening machine suitable for small-sized wire rods to solve the above problems. Summary of the Utility Model

[0005] To achieve the above objectives, the present utility model adopts the following technical solutions:
[0006] A double-station straightening machine suitable for small-sized wire rods, comprising a table plate detachably placed on the top surface of a workbench and a pressure head plate longitudinally slidably arranged above the top surface of the table plate and having a pressure groove at the bottom end. Two support plates capable of controlling the sliding position are horizontally slidably arranged on the top surface of the table plate. Four low-carbon steel straightening bases are detachably arranged on the top surface of one of the support plates, and the center of the top surface of this support plate is a suspended space, and the four low-carbon steel straightening bases are located at the four corners of a square. Two medium-high carbon steel straightening bases in symmetric positions are detachably arranged on the top surface of the other support plate, and the medium-high carbon steel straightening bases are higher than the low-carbon steel straightening bases. A support block capable of longitudinally adjusting the position according to different springback effects is longitudinally slidably arranged at the center of the top surface of the other support plate. Straightening grooves for placing carbon steel bars are provided on the top surfaces of the low-carbon steel straightening bases and the medium-high carbon steel straightening bases.
[0007] As a preferred solution of the present invention, a vertical stud is detachably installed at the center of the top end of the other support plate. The support block is detachably thread sleeved on the vertical stud, and a lock height nut is thread sleeved on the part of the vertical stud below the support block.
[0008] As a preferred solution of the present invention, elevation bases are detachably installed at symmetric positions at the top end of the other support plate, and the two medium-high carbon steel straightening bases are respectively detachably installed at the top ends of the corresponding elevation bases.
[0009] As a preferred solution of the present invention, a cross plate is detachably installed on the top surface of the table plate.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention:
[0013] In this utility model, small-sized wire rods with different material strengths, plasticity, and hardness often form two forms: low-carbon steel and medium-high carbon steel. After straightening, the low-carbon steel basically does not rebound. Therefore, during the straightening process, the support plate with the low-carbon steel straightening base is horizontally moved to the center of the table board, and the low-carbon steel is placed in the straightening grooves on the top surfaces of the two symmetrically-positioned low-carbon steel straightening bases. Subsequently, the low-carbon steel can be straightened by longitudinally moving the pressing head plate, which belongs to direct straightening. For medium-high carbon steel, it basically rebounds after straightening. Therefore, during the straightening process, the support plate with the medium-high carbon steel straightening base is horizontally moved to the center of the table board, and the medium-high carbon steel is clamped in the middle of the straightening grooves of the two medium-high carbon steel straightening bases. At this time, the center of the support plate is exactly the position facing the pressing head plate. By adjusting the longitudinal position of the support block at this position to deal with medium-high carbon steel with different springback effects, the springback of the medium-high carbon steel is weakened, which belongs to over-straightening. In this utility model, for low-carbon steel and medium-high carbon steel, the positions of the two support plates can be switched by horizontal movement, so that the low-carbon steel straightening base and the medium-high carbon steel straightening base are respectively moved to the center of the table board to complete direct straightening and over-straightening respectively. There is no need to disassemble and replace different straightening bases according to the material of the wire rod sample, which belongs to double-station straightening detection. The adjustment is simple and has strong universality, saving time and effort while improving the detection effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The present utility model will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.
[0020] The present utility model provides as Figures 1 - 3A double-station straightening machine applicable to small-sized wire rods is shown, including a table board 1 detachably placed on the top surface of a workbench and a pressure head board 5 longitudinally slidably arranged above the top surface of the table board 1 and having a pressure groove 6 opened at the bottom end. Two support plates 9 with controllable sliding positions are horizontally slidably arranged on the top surface of the table board 1. Four low-carbon steel straightening bases 10 are detachably arranged on the top surface of one of the support plates 9, and the center of the top surface of this support plate 9 is a suspended space, and the four low-carbon steel straightening bases 10 are located at the four corners of a square. Two medium-high-carbon steel straightening bases 12 in symmetric positions are detachably arranged on the top surface of the other support plate 9, and the medium-high-carbon steel straightening bases 12 are higher than the low-carbon steel straightening bases 10. A support block 15 capable of longitudinally adjusting its position according to different springback effects is longitudinally slidably arranged at the center of the top surface of the other support plate 9. Straightening grooves 13 for placing carbon steel bars are opened on the top surfaces of the low-carbon steel straightening bases 10 and the medium-high-carbon steel straightening bases 12. The pressure groove 6 and the straightening grooves 13 are both semi-circular arc grooves, and the diameters are determined according to the diameters of the small-sized wire rods.
[0021] A vertical stud 14 is detachably installed at the center of the top end of the other support plate 9. The support block 15 is detachably thread sleeved on the vertical stud 14, and a height-locking nut 16 is thread sleeved on the part of the vertical stud 14 located below the support block 15. The support block 15 rotates along the vertical stud 14 in a threaded manner to adjust its longitudinal height, and by locking the position of the height-locking nut 16 on the vertical stud 14, the further rotation of the support block 15 can be avoided, thereby locking the longitudinal height of the support block 15.
[0022] Lifting bases 11 are detachably installed at symmetric positions at the top end of the other support plate 9, and the two medium-high-carbon steel straightening bases 12 are respectively detachably installed at the top ends of the corresponding lifting bases 11. The lifting bases 11 can make the medium-high-carbon steel straightening bases 12 higher than the low-carbon steel straightening bases 10, so as to conveniently provide a longitudinal movement space for the support block 15.
[0023] A cross plate 7 is detachably installed on the top surface of the table board 1. Transverse grooves 20 are opened on both side walls of the cross plate 7. Slide seats 8 capable of horizontally sliding along the transverse grooves 20 are detachably installed on both side walls of the support plate 9 in an adapted manner. The slide seats 8 slide horizontally along the transverse grooves 20, which can not only facilitate the horizontal movement of the support plate 9 along the cross plate 7, but also limit the anti-deflection of the horizontal movement of the support plate 9.
[0024] Four support rods 2 are arranged at the top end of the table board 1. A top plate 3 is jointly and detachably installed among the top ends of the multiple support rods 2. A longitudinally telescopic member 4 is detachably installed at the center of the bottom surface of the top plate 3. The pressure head board 5 is detachably installed at the bottom end of the telescopic member 4. The telescopic member 4 can adopt a cylinder or an oil cylinder, and its specific longitudinal stroke can be accurately regulated by a microcomputer control unit, which belongs to a mature existing technology.
[0025] Installation grooves 17 are provided at symmetric positions on both side walls of the support plate 9 adapted to the transverse grooves 20. Installation studs 18 that can penetrate the installation grooves 17 are connected to the adapted positions of the sliding seats 8. Installation nuts 19 are threadedly sleeved on the parts of the installation studs 18 located outside the installation grooves 17. The support plate 9 and the sliding seats 8 are installed and connected by the installation studs 18 and the installation nuts 19, which facilitates quick installation and subsequent quick disassembly and replacement.
[0026] In the present utility model, small-sized wire rods with different material strengths, plasticity, and hardness often form two forms: low-carbon steel and medium-high carbon steel. Among them, the low-carbon steel basically does not rebound after straightening. Therefore, during the straightening process, the support plate 9 with the low-carbon steel straightening base 10 is horizontally moved to the center of the table plate 1, and the low-carbon steel is placed in the straightening grooves 13 on the top surfaces of the two symmetrically positioned low-carbon steel straightening bases 10. Subsequently, the low-carbon steel is straightened by longitudinally moving the pressing head plate 5, which belongs to direct straightening. For medium-high carbon steel, it basically rebounds after straightening. Therefore, during the straightening process, the support plate 9 with the medium-high carbon steel straightening base 12 is horizontally moved to the center of the table plate 1, and the medium-high carbon steel is clamped between the straightening grooves 13 of the two medium-high carbon steel straightening bases 12. At this time, the center of the support plate 9 is also the position directly facing the pressing head plate 5. By adjusting the longitudinal position of the support block 15 at this position, medium-high carbon steel with different springback effects can be dealt with, thereby weakening the springback of the medium-high carbon steel, which belongs to over-straightening. In the present utility model, for low-carbon steel and medium-high carbon steel, the positions of the two support plates 9 can be switched by horizontal movement, so that the low-carbon steel straightening base 10 and the medium-high carbon steel straightening base 12 are respectively moved to the center of the table plate 1 to complete direct straightening and over-straightening respectively. It is not necessary to disassemble and replace different straightening bases according to the material of the wire rod specimen, which belongs to double-station straightening detection. The adjustment is simple and has strong universality, saving time and effort while improving the detection effect.
[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
