Description

Technical Field

[0001] The invention belongs to the technical field of diamond wire saws, and in particular relates to a weighing and classification device and method for a steel substrate for a diamond wire saw. Background Art

[0002] Diamond wire saws are widely used as tools for cutting materials such as stone and concrete. They are mainly composed of steel wire ropes, beads set on the steel wire ropes at intervals, and other components. The beads are composed of a steel matrix and a multi-phase material containing diamonds wrapped on the outer cylindrical surface of the steel matrix. The beads are an important component of the diamond wire saw, and their preparation quality is closely related to the quality of the diamond wire saw.

[0003] The existing preparation technology of beads is usually: first, the multi-phase material mixed with diamonds and the bead steel matrix are automatically cold-pressed into bead cold-pressed blanks, and then the bead cold-pressed blanks are placed in graphite molds for sintering. If the weight of the bead multi-phase material is inconsistent, the height of the bead multi-phase material will be inconsistent, because each mold needs to be loaded with more than 100 bead cold-pressed blanks at the same time, which will cause the heavy beads of the bead multi-phase material to be too dense during sintering due to the high density of the multi-phase material, causing the upper and lower pressure heads of the bead sintering to be easily damaged due to the excessive pressure, and the light beads of the bead multi-phase material are too dense during sintering due to the low density of the multi-phase material, thereby deteriorating their performance. The above problem is one of the main reasons for the low life of the upper and lower pressure heads sintering graphite molds and the unstable quality of the beads. At present, it is mainly solved by frequently adjusting the automatic cold pressing and sintering process parameters, replacing new cold pressing molds and other measures, resulting in low production efficiency and high cost. What is more serious is that the problems of low life of sintered graphite molds and unstable bead quality have not been fundamentally solved. The life of sintered graphite molds varies, and the stability of bead quality has not been qualitatively improved.

[0004] Therefore, it is very important to control the weight of multiphase materials. However, in the process of bead preparation, the steel matrix that constitutes the beads cannot be separated from the multiphase materials. The weight of the multiphase materials cannot be weighed separately. The weight of the multiphase materials can only be estimated by weighing the weight of the beads. In order to make the estimated weight of the multiphase materials accurate, the weight of each grain of steel matrix must be similar. However, if the weight of the steel matrix is ​​kept consistent, the manufacturing cost of the steel matrix will increase significantly. The best way to make the weight of the steel matrix similar is to weigh the weight of the steel matrix grain by grain and use the steel matrix according to weight.

[0005] Based on the above-mentioned deficiencies, the present application proposes a weighing and classification device and method for a steel substrate for a diamond wire saw. By dividing the steel substrate into grades according to weight, a foundation is laid for further dividing the beaded multiphase material into grades according to weight. During sintering, the beaded multiphase materials of the same grade or adjacent grades are loaded into the same mold for sintering, fundamentally solving the industry problems of low life of sintered graphite molds and unstable bead quality.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] A weighing and sorting device for a steel substrate for a diamond wire saw, such as Figure 1 and Figure 2 As shown, it includes a feeding mechanism, a weighing mechanism and a transmission and discharging mechanism.

[0026] The feeding mechanism includes a vibrating feeding tray 2 and a feeding guide rail 1; The weighing mechanism comprises a push-pull material guiding electromagnet 5 , an electronic scale 4 and a weighing pan 3 . The weighing pan 3 is installed on the top of the electronic scale 4 , and the push-pull material guiding electromagnet 5 is installed on one side of the weighing pan 3 .

[0027] The transmission discharging mechanism includes a discharging conveyor belt 6, a push-pull discharging electromagnet 7 and a material box 8. The discharging conveyor belt 6 and the push-pull material guiding electromagnet 5 are respectively located on both sides of the weighing plate 3, and the push-pull discharging electromagnet 7 and the material box 8 are respectively located on both sides of the discharging conveyor belt 6.

[0028] Combined with the above Figure 1 and Figure 2 It can be seen that: The figure shows two vibrating loading trays 2, four feeding guide rails 1, four weighing mechanisms, six push-pull type discharging electromagnets 7 and six material boxes 8, whereby the classification of the steel substrate is achieved by weighing.

[0029] During classification, the steel matrix is ​​guided into the feeding guide rail 1 by the vibrating loading tray 2, and the steel matrix falls into the weighing tray 3 through the feeding guide rail 1. At this time, the electronic scale 4 obtains the weighing weight of the steel matrix. After weighing, the push-pull material guiding electromagnet 5 pushes the steel matrix to the discharge conveyor belt 6. According to the weighing weight and classification standards, the steel matrix is ​​transferred to the target push-pull discharge electromagnet 7 and the material box 8. Under the push of the push-pull discharge electromagnet 7, the steel matrix is ​​pushed into the material box 8 to complete the classification.

[0030] Specifically, regarding the specific feeding of the feeding guide rail 1: Figure 3 and Figure 4 As shown, the feeding guide rail 1 includes a horizontal section and an inclined section connected to the discharge end of the horizontal section, the horizontal section is provided with a liftable feeding top rod 101, and the inclined section is provided with a liftable feeding stop rod 102, in addition, push-pull feeding electromagnets 103 are fixed at the bottom of the horizontal section and the inclined section of the feeding guide rail 1, and the feeding top rod 101 and the feeding stop rod 102 are respectively connected to two push-pull feeding electromagnets 103.

[0031] Specifically, regarding the weighing mechanism, in order to ensure that the weighing can be stably transported to the weighing plate 3, as Figure 3 As shown: the weighing pan 3 is provided with a positioning U-shaped bottom surface.

[0032] Specifically, at least one set of baffle plates 601 is provided on the discharge conveyor belt 6, and each set of baffle plates 601 includes a left plate and a right plate, and the height difference between the left plate and the right plate is 5mm to 15mm, and a storage groove is formed between the left plate and the right plate. As for the operation of the discharge conveyor belt 6, a stepper motor a, a driving wheel b and a driven wheel c are correspondingly provided, and the discharge conveyor belt 6 is sleeved on the outside of the driving wheel b and the driven wheel c, wherein the driving wheel b is driven to rotate by the stepper motor a. In addition, a photoelectric switch d is also installed on one side of the discharge conveyor belt 6, and the start and stop of the stepper motor a is specifically controlled by the detection feedback of the baffle plate 501 by the photoelectric switch d.

[0033] In summary, the control method of the overall device is as follows: (1) Initial position correction Start the stepper motor a to drive the discharge conveyor belt 6 to move forward. When the center of the photoelectric switch d is aligned with the nearest left plate (the baffle plate 601), the photoelectric switch d feedback controls the stepper motor a to stop. At this time, the center line of the feeding guide rail 1 on each electronic scale 4 coincides with the center line of the corresponding group of baffle plates 601, and the center line of the push-pull discharge electromagnet 7 coincides with the center line of the corresponding group of baffle plates 601.

[0034] (2) Loading Start the vibration feeding tray 2 to transport the steel substrate to the feeding guide rail 1; at this time, the feeding top rod 101 and the feeding stop rod 102 are driven by the push-pull feeding electromagnet 103 to be Figure 5 D shows the state in which the steel substrate is continuously fed until the steel substrate fills the feed rail 1 and forms a Figure 5 Specifically, at least the upper portion of the feed stopper rod 102 is provided with a stopper step parallel to the horizontal section of the feed guide rail 1, thereby combining Figure 5 As can be seen from A, the frontmost steel substrate is supported by the horizontal section (feeding guide rail 1) and the feeding stop rod 102.

[0035] like Figure 5 As shown in B and 5C, two push-pull feeding electromagnets 103 are started at the same time, at which time the feeding push rod 101 extends upward from the horizontal section of the feeding guide rail 1, and the material blocking step of the feeding push rod 101 is flush with the horizontal section of the feeding guide rail 1, and the feeding blocking rod 102 is lowered into the inclined section of the feeding guide rail 1, and at least a guiding slope is provided on the top of the feeding push rod 101, which is aligned with the discharge end of the feeding guide rail 1, so that a steel substrate on the front side slides down along the inclined section and is discharged (the discharged steel substrate falls on the weighing pan 3).

[0036] After exporting a steel matrix, such as Figure 5 As shown in C and 5D, the two push-pull feeding electromagnets 103 are started at the same time, at which time the feeding top rod 101 retracts into the horizontal section, and the feeding stop rod 102 extends out of the inclined section, and under the feeding push of the vibrating feeding tray 2, Figure 5 The steel matrix blocked by the feeding push rod 101 in B / 5C continues to move forward and finally recovers. Figure 5 A status.

[0037] (3) Weighing like Figure 3 As shown, the steel substrate slides down the inclined section onto the weighing pan 3, and the weighing weight of the steel substrate is obtained by the electronic scale 4.

[0038] Assume that the number of electronic scales 4 is n, the number of weight-divided gears of the steel substrate is m, the weight of the lightest gear is W0, the weight difference between each gear is a, and the classification assignment is performed according to the weighing weight of the electronic scale 4 as shown in Table 1 below; Table 1

[0039] From the above, assuming n = 4, m = 6, W0 = 1.5g, a = 0.02g, we get the following Table 2: Table 2

[0040] After weighing is completed, the steel substrate is pushed into the storage slot on the discharge conveyor belt 6 by the push-pull material guiding electromagnet 5 .

[0041] (4) Classification of discharge The stepper motor 4 is started to drive the discharge conveyor belt 6 to perform discharge conveyance.

[0042] Assign values ​​G1, G2, G3...G to n weight data measured by n electronic scales n Sort from small to large, and the order is set to K1, K2, K3, ..., Kn The discharging conveyor belt 6 moves forward and stops at K1L (where L represents the distance between adjacent push-pull discharging electromagnets 7), and the I1th push-pull discharging electromagnet 7 is actuated to push the steel substrate stopped beside the I1th push-pull discharging electromagnet 7 into the corresponding material box 8; and then resets; When K1=G1, I1=K1-n+1; When K1=G2, I1=K1-n+2; When K1=G3, I1=K1-n+3; When K1=G n When, I1=K1; The discharging conveyor belt 6 continues to move forward (K2-K1) and stops, and the 12th push-pull discharging electromagnet 7 is actuated to push the steel substrate stopped beside the 12th push-pull discharging electromagnet 7 into the corresponding material box 8; and then resets; When K2=G1, I2=K2-n+1; When K2=G2, I2=K2-n+2; When K2=G3, I2=K2-n+3; When K2=G n When, I2=K2; The discharging conveyor belt 6 continues to move forward (K3-K2) and stops, and the 13th push-pull discharging electromagnet 7 is actuated to push the steel substrate stopped beside the 13th push-pull discharging electromagnet 7 into the corresponding material box 8; and then resets; When K3=G1, I3=K3-n+1; When K3=G2, I3=K3-n+2; When K3=G3, the first I3=K3-n+3; When K3=G n When, I3=K3; The discharge conveyor belt 6 continues to move forward (K n -K n-1 )L stop, first n The push-pull type discharging electromagnet 7 moves and stops at the firstn The steel base body beside the push-pull type discharging electromagnet 7 is pushed into the corresponding material box 8; then reset; When K n =G1, the first n =K n -n+1; When K n =G2, the first n =K n -n+2; When K n =G3, the first n =K n -n+3; When K n =G n At that time, I n =K n .

[0043] If K1, K2, K3, ..., K n If there are multiple adjacent numbers that are the same, multiple push-pull type discharging electromagnets 7 will be activated to simultaneously push multiple steel substrates on the discharging conveyor belt 6 into multiple corresponding material boxes 8.

Because G3=2, the first (=2-4+3) push-pull discharging electromagnet 7 is started, pushing the steel substrate weighing 1.49g into the corresponding material box 8 (W≤1.5 gear), and then resets; The discharge conveyor belt 6 continues to run forward for 2 (=4-2) L and then stops. Because G2=4, the second (=4-4+2) push-pull discharge electromagnet 7 is activated, pushing the steel substrate weighing 1.52g into the corresponding material box 8 (1.5 <W≤1.52 gear), then reset; The discharging conveyor belt 6 continues to run forward for 1 (=5-4) L and stops.

Because G1=6, the third (=6-4+1) push-pull discharging electromagnet 7 is started, pushing the steel substrate weighing 1.54g into the corresponding material box 8 (1.52<W≤1.54 gear), and then resets; Example 2 Take the above n=4, m=6, W0=1.5g, a=0.02g as an example: the weights of the four steel substrates are weighed at the same time as 1.52g / 1.54g / 1.46g / 1.52g respectively, and then the values ​​G1=5 / G2=5 / G3=5 / G4=2 are obtained: The four weight data values ​​5, 5, 5, 2 weighed by the electronic scale 4 are sorted from small to large, and the sorting is 2, 5, 5, 5; The discharging conveyor belt 6 moves forward for 2L and stops.
