Description

Technical Field

[0002] Picks are divided into coal mining machine picks and tunneling machine picks. They are parts of mining and tunneling machines and are used in mining and tunnel construction. When actually processing picks, it is necessary to weld the alloy beans to the inside of the mounting holes reserved on the surface of the picks. This work is mostly completed using a brazing device, which has the advantages of simple operation, precise brazing and stable processing.

[0003] The prior art discloses a single-rope winding type pick welding device with a publication number of CN215615662U, comprising a workbench, a brazing machine, a gantry, a first cylinder, a lower lifting plate, a second cylinder, an upper lifting plate, a fixed base, a telescopic plate, a fixed vertical plate, a connecting plate, a clamping plate, a connecting rod, a heat-insulating collar, a clamping pneumatic motor, a gear, a rack, a support plate, a protective pad, a guide rod and a support column. When in use, the pick workpiece is placed on the upper side of the fixed base, and then the alloy bean is placed on the inner side of the mounting hole at the position of the pick tip cone, and then the clamping pneumatic motor is controlled to drive the gear to rotate, and the rotation of the gear drives the two racks to move in the opposite direction through the meshing of teeth, and the two racks respectively drive the two telescopic plates to move in the opposite direction, and the two telescopic plates respectively drive the two fixed vertical plates to move in the opposite direction, and the two fixed vertical plates are divided by the connecting plate The two clamps are driven to move to the middle position, and the two clamps can fix the pick workpiece on the upper side of the fixed base to improve the stability of the workpiece during welding, and then the telescopic end of the first cylinder is controlled to extend, and the telescopic end of the first cylinder drives the lower lifting plate to move up, and the lower lifting plate drives the fixed base and the pick workpiece on its upper side to move up, so that the pick moves to the inner side of the induction coil of the brazing machine, and then the telescopic end of the second cylinder is controlled to extend to drive the upper lifting plate to move down, and the upper lifting plate drives the thermal insulation ring to move down, so that the thermal insulation ring is pressed on the pointed cone position of the pick workpiece, and the alloy beans are pressed tightly on the inner side of the mounting hole of the pick workpiece, which can prevent the alloy beans from falling off or being adsorbed on the coil during welding. Since the thermal insulation ring is made of asbestos material, it will not generate induced current. At the same time, it has good thermal insulation and flame retardancy, which improves safety in use.

[0004] In the above utility model, the picks and alloy beans have a relatively high temperature after brazing, and there is no cooling structure. It is necessary to wait for the picks and alloy beans to cool down automatically before they can be disassembled. Adding a cooling structure will take away the heat near the coil. The brazing of the next set of picks requires heating the coil again, which reduces the practicality of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a pick brazing alloy bean device, which has the following beneficial effects:

[0018] (1) The utility model adopts an installation frame plate and a protective cover. When the pick brazing alloy bean device is actually used, the pick is first moved between the two groups of clamping plates, and then the control panel is used to operate the forward and reverse motors. The output end of the forward and reverse motors can drive the two-way wire lever to rotate. Since the two-way wire lever and the two groups of screw sleeve threads cooperate with each other, the rotating two-way wire lever can push the two groups of screw sleeves to move closer to or away from each other. The two groups of screw sleeves clamp the pick through the two groups of clamping plates, and the two groups of support plates play a role in supporting the pick. Then, the alloy beans and solder are placed in the mounting holes reserved on the surface of the pick. After that, the control panel is used to operate the first electric telescopic rod and the second electric telescopic rod. The two electric telescopic rods and the brazing machine are working. When the second electric telescopic rod is extended, the pick is moved up through the lifting plate and the concave plate. The two sides of the concave plate can push the inclined surfaces of the two groups of inclined blocks respectively. The two groups of inclined blocks respectively drive the two groups of protective covers away from each other. The pick can pass through the mounting frame plate smoothly and be inserted into the induction coil. When the first electric telescopic rod is extended, the insulation ring is moved down through the mounting plate. The insulation ring can press the alloy beans tightly inside the mounting hole of the pick. At this time, the control panel is used to make the brazing machine work. The external AC power first passes through the rectifier inside the brazing machine to convert the AC voltage into DC voltage. The DC power then enters the inverter inside the brazing machine and is directly The current voltage is converted into high-frequency voltage, and the high-frequency voltage passes through the high-pass filter inside the brazing machine to filter the low-frequency voltage inside the high-frequency voltage. Finally, the high-frequency voltage enters the induction coil. The high-speed changing current flowing through the induction coil will become a high-speed changing magnetic field. When the magnetic lines of force in the magnetic field pass through the pick, countless small eddy currents are generated inside the pick, causing the pick itself to heat up quickly, thereby achieving the heating operation of the pick. The temperature rise of the pick can melt the solder, so that the alloy bean and the pick are brazed. When the brazing is completed, the second electric telescopic rod is reset, and the lifting plate, concave plate and pick will move down, and the concave plate will lose its resistance. The telescopic springs are acted upon by their own elastic force to push the two sets of protective covers to move towards each other. When the two sets of protective covers are in contact with each other, the two sets of protective covers can cover and seal the inside of the mounting frame. The four sets of T-shaped cross bars can ensure the stability of the lateral movement of the two sets of protective covers. Finally, the control panel is used to operate the fan, which can blow out the hot air near the pick through the air guide cover. Due to the presence of the mounting frame and the two sets of protective covers, the flowing gas will not contact the induction coil. The mounting frame and protective covers can dissipate heat for the pick and alloy beans that have been brazed without affecting the temperature near the coil, thereby improving the practicality of the pick brazing alloy bean device.

[0019] (2) The utility model adopts a heat insulation cover. According to the above operation, when the forward and reverse motors are working, the two sets of clamps can clamp the picks. In order to prevent the heat generated by the induction coil from affecting the forward and reverse motors, the control panel is used to operate the micro pump. The micro pump can allow cold water inside the water tank to pass through the water inlet pipe, the spiral pipe, the water outlet pipe and the pumping pipe. When the cold water passes through the spiral pipe, the forward and reverse motors can be cooled down to prevent the heat of the induction coil from affecting the forward and reverse motors. The cold water can enter the water tank through the cold water pipe, and the hot water can be discharged from the water tank through the hot water pipe. By setting up the heat insulation cover, the heat generated by the coil can be prevented from affecting the equipment driving the clamping structure, thereby ensuring the continuous use of the pick brazing alloy bean device.

It is only used without modification, so the control method and circuit connection are not described in detail.

[0037] Working principle:

[0038] When the pick brazing alloy bean device is actually used, the pick is first moved between the two groups of clamping plates 15, and then the control panel is used to operate the forward and reverse motor 18. The output end of the forward and reverse motor 18 can drive the bidirectional wire lever 13 to rotate. Since the bidirectional wire lever 13 and the two groups of lead screw sleeves 14 threads cooperate with each other, the rotating bidirectional wire lever 13 can push the two groups of lead screw sleeves 14 to move closer to or away from each other. The two groups of lead screw sleeves 14 clamp the pick through the two groups of clamping plates 15, and the two groups of support plates 16 play the role of supporting the pick. Then, the alloy beans and solder are placed in the mounting holes reserved on the surface of the pick. After that, the control panel is used to operate the first electric telescopic rod 3, the second electric telescopic rod 9 and the brazing machine 6. When the second electric telescopic rod 9 is extended, the lifting plate 1 0 and the concave plate 12 move the pick upward, the two sides of the concave plate 12 can push the inclined surfaces of the two groups of inclined blocks 22 respectively, the two groups of inclined blocks 22 respectively drive the two groups of protective covers 21 to move away from each other, the pick can smoothly pass through the mounting frame plate 8 and be inserted into the induction coil 7, when the first electric telescopic rod 3 is extended, the heat insulation ring 5 is moved downward through the mounting plate 4, the heat insulation ring 5 can press the alloy beans tightly inside the mounting hole of the pick, at this time, the control panel is used to make the brazing machine 6 work, the external AC power first passes through the rectifier inside the brazing machine 6, so that the AC voltage is converted into DC voltage, the DC power then enters the frequency converter inside the brazing machine 6, and the DC voltage is converted into a high-frequency voltage, the high-frequency voltage passes through the high-pass filter inside the brazing machine 6, and the low-frequency voltage inside the high-frequency voltage is converted The high-frequency voltage is filtered, and finally the high-frequency voltage enters the inside of the induction coil 7. The high-speed changing current flowing through the induction coil 7 will become a high-speed changing magnetic field. When the magnetic lines of force in the magnetic field pass through the pick, countless small eddy currents are generated inside the pick, causing the pick itself to heat up quickly, thereby realizing the heating operation of the pick. The temperature rise of the pick can melt the solder, so that the alloy bean and the pick are brazed. When the brazing is completed, the second electric telescopic rod 9 is reset, and the lifting plate 10, the concave plate 12 and the pick will move downward, and the concave plate 12 will lose its resistance. The four sets of telescopic springs 23 are acted upon by their own elastic force to push the two sets of protective covers 21 to move towards each other. When the two sets of protective covers 21 contact each other, the two sets of protective covers 21 can cover and seal the interior of the mounting frame plate 8. The four sets of The T-shaped cross bar 20 can ensure the stability of the lateral movement of the two groups of protective covers 21. Finally, the control panel is used to operate the fan 24, which can blow out the hot air near the pick through the air guide cover 25. Due to the existence of the mounting frame plate 8 and the two groups of protective covers 21, the flowing gas will not contact the induction coil 7. The mounting frame plate 8 and the protective cover 21 can dissipate heat for the brazed pick and alloy beans without affecting the temperature near the coil, thereby improving the practicality of the pick brazing alloy bean device. At the same time, according to the above operation, when the forward and reverse motor 18 is working, the two groups of clamping plates 15 can clamp the pick. In order to prevent the heat generated by the induction coil 7 from affecting the forward and reverse motor 18, the control panel is used to operate the micro pump 29.The micro pump 29 allows the cold water in the water tank 31 to pass through the water inlet pipe 27, the spiral tube 26, the water outlet pipe 28 and the pumping pipe 30. When the cold water passes through the spiral tube 26, it can cool down the forward and reverse motor 18 to prevent the heat of the induction coil 7 from affecting the forward and reverse motor 18. The cold water can enter the water tank 31 through the cold water pipe 32, and the hot water can be discharged from the water tank 31 through the hot water pipe 33.
