Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drill rods, in particular to a die forging tool for a drill rod joint with a guide hole. Background Art
[0002] Considering that the forging is taken out of the blanking die and then put into the forming die, the outer dimensions of the same part of the blank cannot exceed the size of the forming model cavity, otherwise the blank will be squeezed out of the flash and damage the mold. Usually, the design gives a 1-2mm difference, but this will cause a certain deviation in the coaxiality of the outer diameter of the forging. Especially when forging forgings with deep holes, the superimposed punch and the axis of the forging do not completely coincide, the equipment is overloaded, etc., which makes the coaxiality of the punched deep inner hole and the outer diameter of the forging have a large deviation. When the center deviation is large, the inner hole of the forging will have pits and black skin after machining, and it cannot be fine-turned, resulting in product scrapping.
[0003] The conventional method is to reduce the punching depth of the forging, or reduce the punching hole diameter, to ensure that the inner hole can meet the final size and coaxiality requirements through machining. This can ensure that the product is processed normally, but it increases the input of raw materials and the amount of subsequent machining, increases the machining time and tool wear, etc., and increases production costs.

[0005] The utility model solves the above-mentioned technical problems as follows:
[0006] A die forging tool for a drill rod joint with a guide hole comprises a left stamping part, a drill rod forging part and a right stamping part, wherein a first guide hole and a second guide hole are punched out at both ends of the drill rod forging part through the left stamping part and the right stamping part, a left punch is provided at one end of the left stamping part, a first threaded hole is formed at the end of the left stamping part away from the left punch, a right punch is provided at one end of the right stamping part, and a second threaded hole is provided at the end of the right stamping part away from the right punch.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.
[0008] Furthermore, the left stamping part is connected and fixed to the hydraulic cylinder or the air cylinder through the first threaded hole.
[0009] The beneficial effects of adopting the above further scheme are:
[0010] Stability: Connecting a hydraulic cylinder or a pneumatic cylinder can firmly fix the left stamping part on the working platform to avoid shaking or displacement during the die forging process. This stability is a key factor in ensuring the stability of the die forging process and the forming accuracy.
[0011] Easy to operate: The position and height of the left stamping part can be easily adjusted by connecting the hydraulic cylinder or air cylinder through the threaded hole to adapt to workpieces of different sizes and shapes. The operator can control the movement of the left stamping part by adjusting the pressure of the hydraulic cylinder or air cylinder to achieve flexibility and precision in the die forging process.
[0012] Reliability: The connection with the hydraulic cylinder or pneumatic cylinder usually adopts threaded connection or other reliable connection methods, which can ensure the firmness and sealing of the connection, thereby reducing failures and downtime caused by loose connections or air leakage.
[0013] Applicability: Hydraulic cylinders and pneumatic cylinders are common power components and are widely used in industrial production. Therefore, by connecting with them, the versatility and applicability of die forging tooling can be improved, and it is suitable for die forging equipment and process flows of different types and specifications.
[0014] Furthermore, the right stamping part is connected and fixed to the hydraulic cylinder or the air cylinder through the second threaded hole.
[0015] The beneficial effects of adopting the above further scheme are:
[0016] Balance: By connecting and fixing the right stamping part with the hydraulic cylinder or air cylinder, the structure of the tooling can be balanced to keep it stable during the die forging process. This balance can ensure uniform force distribution during the die forging process and avoid processing deviation or poor forming caused by unbalanced tooling.
[0017] Symmetry: The right stamping part is symmetrical with the left stamping part, and the symmetry of the entire tooling can be maintained by connecting and fixing with the hydraulic cylinder or cylinder. This is crucial for the forming of the workpiece during the die forging process, because symmetry can ensure that the forming pressure and force are evenly distributed, avoiding deformation or uneven deformation of the workpiece.
[0018] Adjustability: After the right punch is connected to the hydraulic cylinder or the air cylinder, the action and position of the right punch can be flexibly controlled by adjusting the working pressure and stroke of the hydraulic cylinder or the air cylinder. This adjustability can meet the die forging requirements of different workpieces, making the tooling more applicable and flexible.
[0019] Synergy: The right stamping part works with the left stamping part, and through the connection and fixation with the hydraulic cylinder or the cylinder, it can better realize the synergy between the various parts of the tooling. This synergy can improve the overall efficiency and performance of the die forging tooling, thereby improving production efficiency and product quality.
[0020] Furthermore, a first fixing hole and a second fixing hole are respectively provided on the outer sides of the left stamping part and the right stamping part.
[0021] The beneficial effects of adopting the above further scheme are:
[0022] Enhanced stability: Through the first and second fixing holes, the left and right stamping parts can be easily fixed on the workbench or other supporting structures. This fixation can enhance the overall stability of the tooling, ensuring that there will be no movement or shaking during the die forging process, thereby ensuring the accuracy and stability of the forming process.
[0023] Improved alignment: The design of the fixing holes allows the left and right stamping parts to be accurately aligned during installation, ensuring that the distance and position relationship between them meet the requirements. This ensures the synergy of the tooling parts during the die forging process and improves the accuracy and consistency of the formed holes.
[0024] Easy to install and replace: The existence of the fixing holes makes the installation and replacement of the tooling easier and more convenient. The operator can quickly install the left and right stamping parts to the required position through the fixing holes, and can also easily replace or adjust them, which improves the flexibility and efficiency of the production line.
[0025] Reduced error risk: The design of the fixing holes reduces the risk of human error during installation. Through the fixing holes, it can be ensured that the position and angle of the left and right stamping parts are accurate, thereby reducing the risk of production errors and quality problems caused by incorrect installation.
[0026] Furthermore, a vent hole is provided on one side of the right stamping part, and the vent hole is connected to the right punch.
[0027] The beneficial effects of adopting the above further scheme are:
[0028] Gas discharge: The presence of the vent allows the gas generated during the die forging process to be discharged smoothly. During the die forging process, gases such as air or extruded gas may be generated. If these gases cannot be discharged in time, it may cause pores or bubbles on the surface of the workpiece, affecting the product quality. The vent is connected to the right punch to ensure that the gas is discharged smoothly from around the workpiece, reducing the poor forming results.
[0029] Prevent excessive air pressure: If the gas cannot be discharged in time, the air pressure may gradually increase during the die forging process. This may have adverse effects on the workpiece, such as deformation or surface defects. Through the vent hole, the air pressure can be effectively prevented from being too high, ensuring the pressure stability during the die forging process, thereby ensuring the accuracy and quality of the forming.
[0030] Process stability: The presence of vent holes helps maintain process stability during die forging. By timely exhausting gas, the impact of process parameter fluctuations can be reduced, the stability and consistency of the die forging process can be maintained, and the processing accuracy and quality stability of the product can be improved.
[0031] Extend mold life: The presence of vent holes also helps to reduce the load on the mold and extend its service life. When too much gas is generated inside the mold, it may increase the force and wear of the mold, resulting in a shortened life. By exhausting the air in time, the burden on the mold can be reduced, its service life can be extended, and the cost of mold replacement and maintenance can be reduced.
[0032] The beneficial effects of the utility model are:
[0033] Guiding function: The left and right stamping parts ensure the accuracy and concentricity of the two ends of the drill rod forging during the forming and punching through the first and second guide holes that are precisely punched out. This guiding function is crucial because during the die forging process, even a slight deviation may lead to incompleteness or folding during the final forging, affecting product quality and process stability.
[0034] Fixed connection: The left and right stamping parts are connected and fixed to the hydraulic cylinder or air cylinder through threaded holes, ensuring the stability and reliability of the tooling during the die forging process. This fixed connection method can effectively prevent the tooling from loosening or shifting during operation, ensuring the safety and stability of production.
[0035] Exhaust function: The exhaust hole of the right stamping part is connected to the right punch, which can timely exhaust the gas generated during the die forging process. This is crucial for the die forging process, because the unexhausted gas may cause air pockets or pores, thus affecting the quality and density of the product. The exhaust function can ensure that the gas in the die forging process is discharged smoothly, ensuring the integrity and consistency of the forming process.
[0036] Stable structure: The left stamping part and the right stamping part are respectively provided with a first fixing hole and a second fixing hole, which can be used to fix the tooling. This structural stability is the key factor to ensure that the tooling maintains its position and posture during the working process. By fixing the tooling, the swing, shaking or dislocation of the tooling can be effectively prevented, and the accuracy and stability of the die forging process can be guaranteed.

The connection with the hydraulic cylinder or the pneumatic cylinder can firmly fix the left stamping part 1 on the working platform to avoid shaking or displacement during the die forging process. This stability is a key factor in ensuring the stability and forming accuracy of the die forging process. The position and height of the left stamping part 1 can be conveniently adjusted by connecting the hydraulic cylinder or the pneumatic cylinder through the threaded hole to adapt to workpieces of different sizes and shapes. The operator can control the movement of the left stamping part 1 by adjusting the pressure of the hydraulic cylinder or the pneumatic cylinder to achieve flexibility and accuracy of the die forging process. The connection with the hydraulic cylinder or the pneumatic cylinder usually adopts a threaded connection or other reliable connection method, which can ensure the firmness and sealing of the connection, thereby reducing failures and downtime caused by loose connection or air leakage. Hydraulic cylinders and pneumatic cylinders are common power elements and are widely used in industrial production. Therefore, by connecting with them, the versatility and applicability of the die forging tooling can be improved, and it is suitable for die forging equipment and process flows of different types and specifications. A right punch 9 is provided at one end of the right stamping part 3, and a second threaded hole 11 is provided at the end of the right stamping part 3 away from the right punch 9. The right stamping part 3 is connected and fixed with the hydraulic cylinder or the cylinder through the second threaded hole 11. The connection and fixation of the right stamping part 3 with the hydraulic cylinder or the cylinder can balance the structure of the tooling and keep it stable during the die forging process. This balance can ensure uniform distribution of force during the die forging process and avoid processing deviations or poor forming caused by unbalanced tooling. The right stamping part 3 is symmetrical with the left stamping part 1, and the symmetry of the entire tooling can be maintained by connecting and fixing with the hydraulic cylinder or the cylinder. This is crucial for the forming of the workpiece during the die forging process, because symmetry can ensure uniform distribution of forming pressure and force and avoid deformation or uneven deformation of the workpiece. After the right stamping part 3 is connected to the hydraulic cylinder or the air cylinder, the movement and position of the right punch 9 can be flexibly controlled by adjusting the working pressure and stroke of the hydraulic cylinder or the air cylinder. This adjustability can adapt to the die forging requirements of different workpieces, making the tooling more applicable and flexible. The right stamping part 3 works in conjunction with the left stamping part 1, and can better achieve the synergy between the various parts of the tooling by connecting and fixing with the hydraulic cylinder or the air cylinder. This synergy can improve the overall efficiency and performance of the die forging tooling, thereby improving production efficiency and product quality. The outer sides of the left stamping part 1 and the right stamping part 3 are respectively provided with a first fixing hole 5 and a second fixing hole 12. Through the first fixing hole 5 and the second fixing hole 12, the left stamping part 1 and the right stamping part 3 can be easily fixed on a workbench or other supporting structure.

This can ensure the synergy of the various parts of the tooling during the die forging process and improve the accuracy and consistency of the forming holes. The existence of the fixing hole makes the installation and replacement of the tooling simpler and more convenient. The operator can quickly install the left stamping part 1 and the right stamping part 3 to the desired position through the fixing hole, and can also easily replace or adjust them, thereby improving the flexibility and efficiency of the production line. The design of the fixing hole reduces the risk of human error during the installation process. Through the fixing hole, it can be ensured that the position and angle of the left stamping part 1 and the right stamping part 3 are accurate, thereby reducing the risk of production errors and quality problems caused by improper installation. A vent 10 is provided on one side of the right stamping part 3, and the vent 10 is connected to the right punch 9. The existence of the vent 10 allows the gas generated during the die forging process to be discharged smoothly. During the die forging process, gases such as air or extruded gas may be generated. If these gases cannot be discharged in time, pores or bubbles may appear on the surface of the workpiece, affecting product quality. By connecting the exhaust hole 10 with the right punch 9, it can ensure that the gas is smoothly discharged from around the workpiece, reducing poor forming results. If the gas cannot be discharged in time, the air pressure may gradually increase during the die forging process. This may have adverse effects on the workpiece, such as deformation or surface defects. The exhaust hole 10 can effectively prevent the air pressure from being too high, ensure the pressure stability during the die forging process, and thus ensure the accuracy and quality of the forming. The existence of the exhaust hole 10 helps to maintain the process stability during the die forging process. By timely removing the gas, the impact of fluctuations in process parameters can be reduced, and the stability and consistency of the die forging process can be maintained, thereby improving the processing accuracy and quality stability of the product. The existence of the exhaust hole 10 also helps to reduce the load on the mold and extend its service life. When too much gas is generated inside the mold, it may increase the stress and wear of the mold, resulting in a shortened life. By exhausting the air in time, the burden on the mold can be reduced, its service life can be extended, and the cost of mold replacement and maintenance can be reduced. The first guide hole 7 and the second guide hole 8 are punched out at both ends of the drill rod forging 2 by the left punching part 1 and the right punching part 3. The first guide hole 7 and the second guide hole 8 play a guiding role during forming punching, ensuring the concentricity during final forging and preventing folding during final forging.
