Description

Technical Field

[0001] This utility model relates to the technical field of drill rod processing, and in particular to a drill rod heading machine. Background Technology

[0002] During drill rod processing, one end of the drill rod needs to be flattened. Chinese utility model patent CN213002052U discloses a drill rod heading machine, which includes a heading mechanism and a feeding mechanism. The heading mechanism includes an upper punch seat and a lower punch seat. A flat punch is provided at the bottom center of the upper punch seat, and a corresponding flat punch hole is provided on the lower punch seat. The feeding mechanism includes a conveyor roller conveyor located on one side of the lower punch seat, and a material rack is provided behind the conveyor roller conveyor. This utility model is designed for drill rod production, facilitating the core extraction of hollow drill rods. It addresses the need to flatten one end of the drill rod by providing a flat punch and corresponding flat punch hole, replacing traditional manual heading. It is equipped with an automatic feeding mechanism that controls the attraction or repulsion tilting of the feeding rod and auxiliary support rod through the change of the magnetic poles of an electromagnet.

[0003] However, the feeding mechanism of the aforementioned chisel heading machine does not separate the chisel being headed from the other chisels when conveying them. This causes the vibration of the chisel being headed to be transmitted to the other chisels, causing them to be shaken out of the feeding mechanism, which is not conducive to smooth feeding and efficient heading. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a drill rod heading machine that can separate the heading drill rod from other drill rods, reduce the impact of vibration on other drill rods, and facilitate smooth feeding and efficient heading.

[0005] This utility model discloses a chisel heading machine, comprising a base plate and a support plate, the support plate being mounted on the base plate at an angle; it also includes a fixed baffle plate, a push plate, a partition plate, a lever, and a heading mechanism. The fixed baffle plate is mounted at the lower end of the support plate, the heading mechanism is mounted on the base plate and located behind the fixed baffle plate, the push plate is slidably mounted on the fixed baffle plate and pushes the chisel towards the heading mechanism, the push plate being located above the support plate, the lower part of the support plate having a slot parallel to the fixed baffle plate and located on the left side of the fixed baffle plate, the partition plate being slidably inserted into the slot, the partition plate having a guide groove, the middle and rear part of the guide groove being located near the lower edge of the partition plate, the front part of the guide groove being inclined upward, the lower end of the push plate having a lever slidably connected to the guide groove; the push plate moves to the front end of the fixed baffle plate, the push plate driving the lever to slide to The front end of the guide groove of the partition allows the lever to push the partition downwards until it is flush with the upper surface of the support plate. Multiple chisels roll on the support plate. The inclined support plate causes the multiple chisels to roll downwards and be blocked by the fixed baffle. The push plate moves backwards along the fixed baffle, pushing the bottom chisel towards the heading mechanism. During the pushing process, the lever slides to the middle of the guide groove of the partition and pushes the partition upwards through the guide groove, causing the partition to rise above the support plate. At this time, the partition separates and blocks the other multiple chisels, so that when the heading mechanism heads the end of the chisel, its vibration will not affect other chisels, preventing other chisels from being shaken out of the support plate. After the end of the chisel is headed, the push plate moves backwards quickly, passing the chisel through the heading mechanism and throwing it out of the support plate for automatic feeding, which is conducive to smooth feeding and efficient heading.

[0006] Preferably, it also includes a drive wheel, a driven wheel, and a transmission belt. The drive wheel is rotatably mounted on the front end of the fixed baffle, and the driven wheel is rotatably mounted on the rear end of the fixed baffle. The transmission belt is fitted onto the drive wheel and the driven wheel, and the push plate is connected to the transmission belt. The drive wheel and the driven wheel drive the transmission belt to rotate, and the transmission belt drives the push plate to move back and forth along the fixed baffle, thereby driving the push plate to push the chisel for automatic feeding and heading.

[0007] Preferably, it also includes a vortex tube, which is installed at the rear end of the fixed baffle; the push plate pushes the drill rod to move backward a certain distance, so that the end of the drill rod extends into the vortex tube, and the vortex tube heats the end of the drill rod.

[0008] Preferably, it also includes two side plates, which are respectively installed on the front and rear edges of the upper surface of the support plate; the two side plates constrain and limit the chisel that is rolled and conveyed on the support plate, thereby improving the feeding accuracy of the chisel.

[0009] Preferably, the heading mechanism includes a mounting base, a lower mold, two sliding columns, an upper mold, a pusher, and a spring damper. The mounting base is mounted on a base plate, and the lower mold is mounted on the bottom of the mounting base. The upper end face of the lower mold has a shaping slot 1. The two sliding columns are vertically mounted on the mounting base, and the upper mold is slidably mounted on the two sliding columns, located above the sliding columns. The lower end face of the upper mold has a shaping slot 2, which is arranged opposite to the shaping slot 1. The fixed end of the pusher is mounted on the upper end of the mounting base, and the piston rod of the pusher is equipped with a spring damper, which is connected to the upper mold. After the end of the chisel is heated, it is conveyed between the shaping slot 1 and shaping slot 2 of the lower and upper molds. The piston rod of the pusher reciprocates and extends, pushing the upper mold to reciprocate up and down along the two sliding columns through the spring damper. This causes the upper mold to work with the lower mold to impact and head the end of the chisel. The shaping slot 1 and shaping slot 2 work together to shape the end of the chisel into a pointed tip. The spring damper buffers the upper mold, improving the heading efficiency.

[0010] Preferably, the device also includes a contact switch and a screw. The contact switch is installed on the upper end face of the lower mold, and the screw is rotatably screwed onto the upper mold. The lower end of the screw extends out of the lower end face of the upper mold, and the screw is aligned with the contact switch. When the upper mold descends and the screw contacts the contact switch, the contact switch sends a signal to the controller of the pusher, causing the piston rod of the pusher to stop and retract. This limits the stroke of the upper mold by the screw and the contact switch. Rotating the screw adjusts the length of the lower end extending out of the lower end face of the upper mold, achieving different heading effects.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The push plate moves to the front end of the fixed baffle, and the push plate drives the lever to slide to the front end of the guide groove of the partition, so that the lever pushes the partition downward through the guide groove until it is flush with the upper surface of the support plate. Multiple chisels are rolled on the support plate. The inclined support plate causes multiple chisels to roll downward and be blocked by the fixed baffle. The push plate moves backward along the fixed baffle, so that the push plate pushes the bottom chisel towards the heading mechanism. During the pushing process, the lever slides to the middle of the guide groove of the partition and pushes the partition upward through the guide groove, so that the partition rises above the support plate. At this time, the partition separates and blocks the other multiple chisels, so that when the heading mechanism heads the end of the chisel, its vibration will not affect other chisels, and other chisels will not be shaken out of the support plate. After the end of the chisel is headed, the push plate moves backward quickly to push the chisel through the heading mechanism and throw it out of the support plate for automatic feeding, which is conducive to smooth feeding and efficient heading.

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 6As shown, a chisel heading machine includes a base plate 1 and a support plate 2. The support plate 2 is mounted on the base plate 1 and is inclined. It also includes a fixed baffle plate 3, a push plate 4, a partition plate 5, a lever 6, and a heading mechanism. The fixed baffle plate 3 is mounted at the lower end of the support plate 2. The heading mechanism is mounted on the base plate 1 and located behind the fixed baffle plate 3. The push plate 4 is slidably mounted on the fixed baffle plate 3, and pushes the chisel towards the heading mechanism. The push plate 4 is located above the support plate 2. A slot is provided at the lower part of the support plate 2, parallel to the fixed baffle plate 3 and located on the left side of the fixed baffle plate 3. The partition plate 5 is slidably inserted into the slot. In the trough, a guide groove is provided on the partition plate 5. The middle and rear part of the guide groove is located near the lower edge of the partition plate 5, and the front part of the guide groove is inclined upward. A lever 6 is installed at the lower end of the push plate 4, and the lever 6 is slidably connected to the guide groove. It also includes a driving wheel 7, a driven wheel 8, and a transmission belt 9. The driving wheel 7 is rotatably installed at the front end of the fixed baffle plate 3, and the driven wheel 8 is rotatably installed at the rear end of the fixed baffle plate 3. The transmission belt 9 is fitted on the driving wheel 7 and the driven wheel 8, and the push plate 4 is connected to the transmission belt 9. It also includes a vortex tube 10, which is installed at the rear end of the fixed baffle plate 3. It also includes two side plates 11, which are respectively installed on the front and rear edges of the upper surface of the material support plate 2.

[0023] The driving wheel 7 and driven wheel 8 drive the transmission belt 9 to rotate. The transmission belt 9 drives the push plate 4 to move back and forth along the fixed baffle 3, thereby driving the push plate 4 to push the chisel for automatic feeding and heading. The push plate 4 moves to the front end of the fixed baffle 3, and the push plate 4 drives the lever 6 to slide to the front end of the guide groove of the partition 5, so that the lever 6 pushes the partition 5 downward through the guide groove until it is flush with the upper surface of the support plate 2. Multiple chisels are rolled and placed on the support plate 2. The two side plates 11 constrain and limit the chisels that are rolled and conveyed on the support plate 2. The inclined support plate 2 causes multiple chisels to roll downward and be blocked by the fixed baffle 3. The push plate 4 moves backward along the fixed baffle 3, so that the push plate 4 moves the bottommost chisel backward a certain distance. The end of the drill rod is inserted into the eddy current tube 10, which heats the end of the drill rod. After the end is heated, the push plate 4 pushes the end of the drill rod toward the heading mechanism. During the pushing process, the lever 6 slides to the middle of the guide groove of the partition plate 5 and pushes the partition plate 5 upward through the guide groove, so that the partition plate 5 rises above the material support plate 2. At this time, the partition plate 5 separates and blocks other drill rods, so that when the heading mechanism heads the end of the drill rod, its vibration will not affect other drill rods and prevent other drill rods from being shaken out of the material support plate 2. After the end of the drill rod is headed, the push plate 4 moves backward quickly to push the drill rod through the heading mechanism and throw it out of the material support plate 2 for automatic feeding, which is conducive to smooth feeding and efficient heading.

[0024] Example 2

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 and Figure 7 As shown, based on Embodiment 1, the heading mechanism includes a mounting base 12, a lower mold 13, two sliding pillars 14, an upper mold 15, a pusher 16, and a spring damper 17. The mounting base 12 is mounted on the base plate 1, and the lower mold 13 is mounted on the bottom of the mounting base 12. A shaping slot is provided on the upper end face of the lower mold 13. The two sliding pillars 14 are vertically mounted on the mounting base 12, and the upper mold 15 is slidably mounted on the two sliding pillars 14. The upper mold 15 is located above the sliding pillars 14, and the lower part of the upper mold 15... The end face is provided with a second shaping slot, which is arranged opposite to the first shaping slot. The fixed end of the pusher 16 is installed on the upper end of the mounting base 12. The piston rod of the pusher 16 is equipped with a spring damper 17, which is connected to the upper mold 15. It also includes a contact switch 18 and a screw 19. The contact switch 18 is installed on the upper end face of the lower mold 13. The screw 19 is rotatably screwed onto the upper mold 15. The lower end of the screw 19 extends out of the lower end face of the upper mold 15 and is aligned with the contact switch 18.

[0026] After the end of the drill rod is heated, it is conveyed between the first and second shaping slots of the lower mold 13 and the upper mold 15. The piston rod of the pusher 16 reciprocates and extends, pushing the upper mold 15 to rise and fall along the two slide columns 14 through the spring damper 17. This causes the upper mold 15 to work with the lower mold 13 to impact and head the end of the drill rod. The first and second shaping slots work together to shape the end of the drill rod into a pointed tip. The spring damper 17 buffers the upper mold 15, improving the heading efficiency. When the upper mold 15 descends and the screw 19 contacts the contact switch 18, the contact switch 18 sends a signal to the controller of the pusher 16, causing the piston rod of the pusher 16 to stop and retract. This causes the screw 19 and the contact switch 18 to limit the stroke of the upper mold 15. Rotating the screw 19 adjusts the length of the lower end extending from the lower end face of the upper mold 15, achieving different heading effects.

[0027] like Figures 1 to 7As shown, this utility model discloses a drill bit heading machine. During operation, the push plate 4 first moves to the front end of the fixed baffle 3. The push plate 4 drives the lever 6 to slide to the front end of the guide groove of the partition 5, causing the lever 6 to push the partition 5 downwards until it is flush with the upper surface of the support plate 2. Multiple drill bits are rolled onto the support plate 2. The inclined support plate 2 causes the drill bits to roll downwards and be blocked by the fixed baffle 3. Then, the push plate 4 moves backwards along the fixed baffle 3, pushing the lowest drill bit towards the vortex tube 10. During this pushing process, the lever 6 slides to the middle of the guide groove of the partition 5 and pushes the partition 5 upwards through the guide groove, causing the partition 5 to rise above the support plate 2. At this point, the partition 5 separates and blocks the other drill bits. The vortex tube 10 then... The end of the drill rod is heated, and then the heated end of the drill rod is conveyed between the first and second shaping slots of the lower mold 13 and the upper mold 15. The piston rod of the pusher 16 reciprocates and extends, pushing the upper mold 15 to rise and fall along the two slide columns 14 through the spring damper 17. This causes the upper mold 15 to work with the lower mold 13 to impact and head the end of the drill rod. The first and second shaping slots work together to shape the end of the drill rod into a pointed shape. Since the partition plate 5 separates and blocks other drill rods, the vibration of the upper mold 15 working with the lower mold 13 to head the end of the drill rod will not affect other drill rods. Finally, after the end of the drill rod is headed, the push plate 4 moves backward quickly to push the drill rod through the heading mechanism and out of the material support plate 2 for automatic unloading.

[0028] The main functions achieved by this utility model are:

[0029] 1. It can separate the drill rod to be driven from other drill rods, reducing the impact of vibration on other drill rods, which is conducive to smooth feeding and efficient driving;

[0030] 2. By cooperating with the lower mold 13 and the upper mold 15 and using the spring damper 17 for shock absorption, the heading efficiency is improved;

[0031] 3. The distance between the lower mold 13 and the upper mold 15 can be adjusted to achieve different heading effects.

[0032] The rod heading machine of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired effect can be implemented. The material support plate 2, push plate 4, lever 6, drive wheel 7, driven wheel 8, transmission belt 9, eddy tube 10, lower mold 13, sliding column 14, upper mold 15, pusher 16, spring shock absorber 17, contact switch 18, and screw 19 of the rod heading machine of this utility model are commercially available.
