Description

Technical Field

[0001] The present invention relates to the technical field of corrosion-resistant box manufacturing, and in particular to a method and a device for manufacturing underground corrosion-resistant box materials for mines. Background Art

[0002] In underground mines, the inclined shafts, vertical shafts, and adit tunnels involved in underground mine development are sometimes also referred to as mine shafts. Mine development has a significant and far-reaching impact on the overall production and construction of metal mines or coal mines. It not only affects the amount of capital construction work, initial investment, and the speed of mine construction, but more importantly, it determines the long-term production conditions and technical and economic indicators of the mine. The environment in mines is relatively humid, so when the box is used, it is easily corroded by moisture, which places higher demands on the box's corrosion resistance.

[0003] In the process of producing and manufacturing the box body, the traditional underground corrosion-resistant box body material manufacturing device for mines needs to drill holes in the box body to ensure the heat dissipation and convenience of the box body installation. After the drilling operation is completed on the box body, it is often necessary to manually remove the box body and put in a new box body for drilling. The operation of raising and lowering the box body is cumbersome, labor-intensive, and inefficient.

[0013] Preferably, one end of the limiting rod is fixedly connected to a support plate, and the support plate is fixedly connected to one end of the first spring.

[0014] Preferably, a forward and reverse motor is provided on the top of the drilling device body, and the output end of the forward and reverse motor is fixedly connected to the reciprocating screw rod.

[0015] Preferably, the drilling device body is provided with two or more positioning sensors.

[0016] A method for manufacturing underground corrosion-resistant box materials for mines using the aforementioned manufacturing device comprises the following steps:

[0017] 1) Obtaining a corrosion-resistant box casting by one-time casting;

[0018] 2) heat treating the casting: keeping the casting in an oven at 450° C. to 500° C. for 6 to 8 hours, taking it out and air-cooling it for 6 hours, and then keeping the casting in an oven at 200° C. for 4 to 6 hours;

[0019] 3) performing rough lathe processing on the heat-treated casting;

[0020] 4) using the aforementioned manufacturing device to perform a drilling operation on the rough-machined casting: starting the forward and reverse motors, the reciprocating screw rotates to drive the two clamping plates to move relative to each other, and after clamping the box body, the drilling device body drills the box body, the reciprocating screw rotates to simultaneously drive the first gear to rotate, the first gear drives the rack, the vertical plate, the first telescopic rod, and the protrusion to move forward, the protrusion squeezes the second telescopic rod to retract, the first gear rotates to simultaneously drive the second gear to rotate, the second gear drives the slider to move in the direction of the first spring via the threaded rod, and the slider then drives the first telescopic rod to retract;

[0021] 5) After drilling is completed, the forward and reverse motors in the manufacturing device reverse, the two clamps release their fixation on the box, and the slider is threadedly connected to the threaded rod under the elastic force of the first spring and moves in the direction of the second spring. At this time, the slider drives the first telescopic rod to extend, and at the same time, the rack drives the vertical plate to move toward the box, driving the protrusion to push out of the box;

[0022] 6) performing surface treatment and spray coating on the drilled casting to obtain a corrosion-resistant box product;

[0023] 7) The controller collects the timing results of the timer and the voltage value of the stress detection circuit, and calculates the drilling impulse based on the timing results and the voltage value, calculates the variance of the drilling impulse of a unified batch, and outputs the processing quality consistency information of the corrosion-resistant box material based on the comparison result of whether the variance exceeds the set threshold.

[0024] The present invention provides a method and device for manufacturing underground corrosion-resistant box materials for mines, which, compared with the prior art, have at least the following beneficial effects:

[0025] 1. The manufacturing device of the present invention is linked by an ejection assembly and a translation assembly. Specifically, the first telescopic rod drives the protrusion to move, and the protrusion squeezes the second telescopic rod to retract. At the same time, the rotation of the first gear drives the rotation of the second gear, and the second gear drives the slider to move in the direction of the first spring through the threaded rod. At this time, the slider can be moved to the smooth surface of the threaded rod. When the slider moves in the direction of the first spring, it can drive the first telescopic rod to retract, so that the ejection assembly and the translation assembly can be moved out of the drilling operation range when performing the drilling operation to avoid affecting the drilling operation.

[0026] 2. In the manufacturing device and method of the present invention, after the drilling operation is completed, the ejection assembly and the translation assembly move in opposite directions, thereby ejecting the box. Simultaneously, during the ejection process, the box is subjected to the combined horizontal and vertical forces of the protruding blocks, enabling the box to rotate during the ejection process, facilitating subsequent manual handling and processing. Through this structural design, the present invention enables automatic ejection and rotation of the box, significantly reducing manual labor intensity and improving work efficiency.

[0027] 3. In order to control the deflection angle of the box during the pushing process and facilitate manual handling, the present invention further provides a bottom plate protrusion array at the bottom of the drilling device body. By setting the density of the bottom plate protrusions, the deflection angle of the box can be controlled within a reasonable range. Furthermore, the protrusion array is arranged in a right-angled triangle, with the two right-angled sides located on one side of the threaded rod and the protrusion side clamping plate respectively, and the protrusion density can be unevenly set to control the deflection angle of the box within 30°~60°.

[0028] 4. The manufacturing device of the present invention is equipped with a piezoelectric sensor, a timer, and a controller. When the voltage fluctuation in the circuit containing the piezoelectric sensor exceeds a threshold during the drilling process, it indicates that the hole in the box has been drilled, thereby achieving automatic control of the drilling process and realizing the timing of the drilling operation. In addition, the timing results and the stress detection circuit can further achieve consistency control of the box processing quality. Specifically, based on the timing duration and the voltage signal fed back by the circuit, the controller can output the drilling impulse of the same batch of boxes. By calculating the variance of the drilling impulse, the processing quality and processing consistency of each batch of underground corrosion-resistant box materials for mines can be determined.

[0039] Example 1

[0040] This embodiment provides a device for manufacturing underground corrosion-resistant box materials for mines.

[0041] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The manufacturing device includes a drilling device body 1, a reciprocating screw 2 is provided on the top of the drilling device body 1, and two splints 3 are connected to the outside of the reciprocating screw 2 through a ball nut pair. The two splints 3 are slidably connected to the top of the drilling device body 1, and the movement directions of the two splints 3 are opposite. A first gear 4 is fixedly connected to the outside of the reciprocating screw 2, and a rack 5 is meshed with the bottom of the first gear 4. One side of the rack 5 is fixedly connected to a vertical plate 6, and one side of the vertical plate 6 is fixedly connected to a first telescopic rod 7. One side of the first telescopic rod 7 is provided with a pushing assembly, and the pushing assembly includes a protrusion 8, which is fixedly connected to one side of the first telescopic rod 7, and one side of the protrusion 8 is fixedly connected to the second telescopic rod 9. One side of the second telescopic rod 9 is fixedly connected to a slider 12, and a translation assembly is provided inside the slider 12. The translation assembly includes a threaded rod 11, which is threadedly connected to the inside of the slider 12, and a second gear 10 is fixedly connected to the outside of the threaded rod 11. The second gear 10 is meshed with the top of the first gear 4, and a first spring 13 and a second spring 14 are provided on the outside of the threaded rod 11.

[0042] By setting the first spring 13 and the second spring 14, the sliding contact between the slider 12 and the threaded rod 11 can be changed into a threaded connection, thereby driving the slider 12 to reciprocate. A support plate 15 is fixedly connected to the top of the drilling device body 1. The support plate 15 is rotatably connected to the outside of the reciprocating screw rod 2 and the threaded rod 11. The support plate 15 is fixedly connected to one end of the second spring 14. By setting the support plate 15, the reciprocating screw rod 2 and the threaded rod 11 can be supported, which facilitates the reciprocating screw rod 2 and the threaded rod 11 to run more smoothly. To increase stability, the support plate 15 is fixedly connected to a limit rod 16, and the limit rod 16 is slidably connected to the inside of the slider 12. By setting the limit rod 16, the slider 12 can be limited, so that the slider 12 can move linearly. One end of the limit rod 16 is fixedly connected to a support plate 17, and the support plate 17 is fixedly connected to one end of the first spring 13. By setting the support plate 17, the first spring 13 can be supported. A forward and reverse motor 18 is provided on the top of the drilling device body 1, and the output end of the forward and reverse motor 18 is fixedly connected to the reciprocating screw 2.

[0043] When using this embodiment: first start the forward and reverse motor 18. Since the output end of the forward and reverse motor 18 is fixedly connected to the reciprocating screw rod 2, the forward and reverse motor 18 drives the reciprocating screw rod 2 to rotate. The rotation of the reciprocating screw rod 2 drives the two clamping plates 3 to move relative to each other. At this time, the box body can be clamped. After clamping, the drilling device body 1 can be started to drill the box body. At the same time, the rotation of the reciprocating screw rod 2 drives the first gear 4 to rotate. The rotation of the first gear 4 drives the rack 5 to move to one side. The rack 5 moves to one side and drives the vertical plate 6 to move to one side. The vertical plate 6 moves to one side and drives the first telescopic rod 7 to move to one side. The first telescopic rod 7 moves to one side. The movement of the retraction rod 7 to one side drives the protrusion 8 to move to one side. The movement of the protrusion 8 to one side can squeeze the second telescopic rod 9 to retract. At the same time, the rotation of the first gear 4 drives the second gear 10 to rotate. The rotation of the second gear 10 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the slider 12 to move in the direction of the first spring 13. At this time, the slider 12 can be moved to the smooth surface of the threaded rod 11. When the slider 12 moves in the direction of the first spring 13, it can drive the first telescopic rod 7 to retract, so that the pushing assembly and the translation assembly can be moved out of the drilling operation range when the drilling operation is performed, so as to avoid affecting the drilling operation.

[0044] When the processing of a box is completed, the forward and reverse motor 18 can be reversed. According to the same working principle as above, the two clamps 3 are driven to loosen the fixation on the box. At the same time, the slider 12 is subjected to the elastic force of the first spring 13, which can change the sliding contact between the slider 12 and the threaded rod 11 into a threaded connection. At this time, the slider 12 moves in the direction of the second spring 14, and the slider 12 drives the first telescopic rod 7 to extend. At the same time, the rack 5 drives the vertical plate 6 to move toward the box, so that the box can be quickly pushed out. Once pushed out, it can be quickly retracted, so as not to affect the processing and drilling of the next workpiece. In the process of pushing out the box, due to the joint action of the pushing component and the translation component, the force of the protrusion 8 on the box can be decomposed into components in the horizontal and vertical directions, thereby realizing the posture deflection during the box pushing process, which is convenient for subsequent manual handling and processing needs.

[0045] Example 2

[0046] When the box body deflection angle is about 45 degrees and the deflection angle is suspended outside the bottom plate of the manufacturing device, the difficulty of manual handling can be greatly reduced. Therefore, in order to control the deflection angle of the box body during the pushing process and facilitate subsequent manual handling, based on Example 1, refer to Figure 2The manufacturing device of this embodiment further includes: the bottom plate of the drilling device body 1 is provided with a raised dot matrix 21. By setting the density of the bottom plate protrusions, the deflection angle of the box body can be controlled within a reasonable range. Furthermore, the raised dot matrix 21 can be arranged in a right triangle as a whole, with the right angle of the triangle located at the starting position of the protrusion 8, and the two right-angled sides of the triangle located on the threaded rod 11 and the side of the clamping plate 3 on the side of the protrusion 8. Furthermore, the raised dot matrix 21 is unevenly distributed on the bottom plate of the drilling device body 1. With the vertical center line of the threaded rod 11 as the boundary, the protrusion density on the side away from the protrusion 8 is greater than the protrusion density on the side of the protrusion. Therefore, when the box body is pushed out, the friction force generated by the raised dot matrix 21 can offset part of the torsional force generated by the protrusion 8 on the box body, thereby preventing the box body from flipping over at an excessive angle, so that the deflection angle of the box body is controlled within 30° to 60°.

[0047] Example 3

[0048] Based on Example 2, please refer to Figure 2 The manufacturing device in this embodiment further includes a piezoelectric sensor 20 arranged on the bottom plate of the drilling device body 1, and a stress detection circuit including the piezoelectric sensor 20.

[0049] During the drilling process, the piezoelectric sensor 20 is subjected to the weight of the box and the pressure of the drilling device. At the moment the hole is drilled, the pressure of the drilling device on the box and the piezoelectric sensor 20 drops sharply, and the pressure on the piezoelectric sensor 20 changes significantly, causing the voltage in the stress detection circuit where the piezoelectric sensor 20 is located to drop significantly. When the reduction value exceeds the set threshold, it can be determined that the drilling operation of the box has been completed. At this time, a signal can be sent to the staff by means of sound and light alarms, prompting the operator to proceed to the next step.

[0050] The manufacturing device also includes a timer. The timer and stress detection circuit are each connected to the controller to calculate drilling duration. Specifically, at the start of drilling, the piezoelectric sensor 20 experiences pressure from the drilling device in addition to the weight of the housing, causing a transient increase in the voltage of the stress detection circuit. When the controller detects that the voltage has increased beyond a threshold, indicating the start of drilling, the timer begins. As drilling concludes, as previously described, the voltage in the stress detection circuit drops transiently, and the controller controls the timer to terminate.

[0051] Based on the voltage value of the stress detection circuit and the detection results of the timer, the controller can calculate the impulse generated during the drilling process. Because the product quality of corrosion-resistant housings within the same batch may vary, by statistically calculating the impulse during the drilling process of each housing within the same batch or utilizing quality control control theories such as Six Sigma, the distribution of impulses for each batch can be determined, thereby determining the processing quality and consistency of each batch of underground corrosion-resistant housing materials for mines. The specific detection process can be found in the relevant description of the applicant's invention entitled "A Manufacturing Apparatus and Method for a Shooting Cylinder Block for an Injection Molding Machine" and will not be repeated here.

[0053] Based on Example 3, this embodiment further includes:

[0054] A support plate 15 is fixedly connected to the top of the drilling device body 1, and the support plate 15 is rotatably connected to the outside of the reciprocating screw rod 2 and the threaded rod 11. The support plate 15 is fixedly connected to one end of the second spring 14. By setting the support plate 15, the reciprocating screw rod 2 and the threaded rod 11 can be supported, thereby improving the operating stability of the reciprocating screw rod 11 and the threaded rod 2.

[0055] A limiting rod 16 is fixedly connected to the interior of the support plate 15 , and the limiting rod 16 is slidably connected to the interior of the slider 12 . By providing the limiting rod 16 , the slider 12 can be limited so that the slider 12 can perform linear reciprocating motion.

[0057] A forward and reverse motor 18 is provided on the top of the drilling device body 1 , and the output end of the forward and reverse motor 18 is fixedly connected to the reciprocating screw rod 2 .
