Technical Field

[0001] The present invention relates to the technical field of cold heading manufacturing of alloy parts, and particularly to a cold heading device for the production and processing of alloy fasteners. Background Art

Its working principle is to continuously extrude and form a metal bar or wire through a die, including steps such as feeding, shearing, pre-forming, multi-process forming, and finished product output. Cold heading equipment has the advantages of high efficiency, high quality, material saving, and low cost, and is widely used in multiple fields such as automobiles, machinery, construction, and electronics.

[0003] Currently, when cold heading equipment produces screw parts, the screws are uniformly fed. However, in the actual production process, the production quality of the screws is affected by various factors, and there is no quality inspection setting during the production of the screws.

Second pressure sensors are installed at the top and bottom ends of the inner wall of the sliding groove. Second spring telescopic rods are installed on the side wall of the connecting block close to the second pressure sensors, and one end of the second spring telescopic rod close to the second pressure sensor abuts against the second pressure sensor.

An air inlet hole is penetrated through the inner wall of the air inlet groove on one side close to the fixing rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, by providing an auxiliary block and an abutting block, the rotating rollers on the two abutting blocks abut against the outer side of the rough blank. During the upward movement of the rough blank, the rotating rollers roll while abutting against the outer side of the rough blank. If the rough blank cracks or expands during the cold heading process, then the abutting block will be squeezed by the deformed part of the rough blank and squeeze the first pressure sensor. The first pressure sensor transmits the detected pressure value to the background control system and compares it with the standard pressure value. If the detected pressure value exceeds the standard pressure value, it indicates that the rough blank has deformed in this production step; After detecting that the rough blank has deformed, while the two abutting blocks are squeezing and abutting against the rough blank, they move towards the waste material groove. When the rough blank moves above the waste material groove, the two auxiliary blocks move away from each other, so that the two abutting blocks no longer abut against the rough blank. Immediately, the rough blank can be discharged at the waste material groove at this place. Through this operation method, not only can the classification and discharging of qualified and unqualified workpieces be completed, but also by setting a plurality of waste material grooves, the staff can accurately know at which step the rough blank is damaged during processing, so that the equipment can be detected and repaired more accurately according to the results.

[0016] In the present invention, by providing a positioning rod and a clamping plate, the two clamping plates move towards each other to complete the clamping of the rough blank. When the upper die head rises, if there is a clamping situation between the upper die head and the rough blank, at this time, the connecting block will slide upward inside the sliding groove and drive the second spring telescopic rod to squeeze the second pressure sensor. The second pressure sensor transmits the measured pressure value to the background control system, and the background control system compares the measured pressure value with the standard pressure value. If the pressure value exceeds the preset pressure value, it indicates that there is a clamping situation between the rough blank and the upper die head; When the clamping plate clamps the rough blank after cold heading from the die cavity of the lower die set, if there is a clamping situation between the rough blank and the die cavity of the lower die set, the connecting block will slide downward inside the sliding groove, driving the second spring telescopic rod to squeeze the second pressure sensor. The second pressure sensor transmits the measured pressure value to the background control system. The background control system compares the measured pressure value with the standard pressure value. If the pressure value exceeds the preset pressure value, it indicates that there is a clamping situation between the rough blank and the die cavity of the lower die set. When it is detected that there is a clamping situation between the rough blank and the die cavities in the upper die head and the lower die set during the processing of the rough blank, the staff can immediately detect the upper die head and the lower die set to prevent the upper die head and the lower die set from being damaged more severely during use; When the clamping plate clamps the rough blank at the feeding trough, the fan connected to the air inlet hole starts, and air enters the air inlet groove. Then it flows out from the air outlet hole and blows from above the rough blank to below. Through this operation method, the dust on the outside of the rough blank can be removed, and the rough blank can be cleaned, preventing the dust attached to the rough blank from polluting the inside of the upper die head and the lower die set; When the clamping plate clamps the rough blank during the cold heading process of the upper die head and the lower die set, by blowing air out through the air outlet hole, the auxiliary cooling of the rough blank and the lower die set can be achieved.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figures 1-10 A cold heading device for producing and processing alloy fasteners comprises a bottom workbench 1 and a top workbench 2. The top workbench 2 is installed above the top of the bottom workbench 1 through a support rod. A lower die set 6 is installed on the top of the bottom workbench 1. A plurality of hydraulic rods 4 are installed at the bottom of the top workbench 2. The telescopic ends of the hydraulic rods 4 face downward. A lifting plate 3 is provided below the top workbench 2. The telescopic ends of the hydraulic rods 4 are connected to the top of the lifting plate 3. A plurality of upper die heads 5 are evenly provided at the bottom of the lifting plate 3. A clamping mechanism and a detection mechanism are provided above the lower die set 6 at the top of the bottom workbench 1. The clamping mechanism is located above the detection mechanism. A material discharge trough 13 is penetrated through the top of one end of the bottom workbench 1. A material loading trough 15 is penetrated through the top of the other end of the bottom workbench 1. A plurality of waste troughs 14 are evenly penetrated through the top of the bottom workbench 1 at one side of the lower die set 6. The clamping mechanism can automatically clamp and load the rough blank, the testing mechanism can detect the quality of the rough blank after cold heading, and can classify and unload the qualified and unqualified cold heading parts.

[0021] As a technical optimization solution of the present invention, the clamping mechanism includes a first lifting rod 10 and a clamping plate 24. Two first lifting rods 10 are movably installed on the top of the bottom workbench 1, and multiple clamping plates 24 are evenly and movably installed on the sides close to each other at the bottom of the two first lifting rods 10. The clamping work of the rough blank can be completed by the clamping plate 24, and the first lifting rod 10 can drive the clamping plate 24 to be used in different positions.

[0022] As a technical optimization solution of the present invention, both ends of the bottom of the first lifting rod 10 are connected with second electric lifting rods 9. The installation ends of the second electric lifting rods 9 face downward. At the top of the bottom workbench 1, moving sliding grooves 11 are opened near the second electric lifting rods 9. The bottom of the second electric lifting rod 9 is installed with moving electric sliders 12, and the moving electric sliders 12 are slidably installed inside the moving sliding grooves 11. By the sliding of the moving electric sliders 12 in the moving sliding grooves 11, the second electric lifting rods 9 and the first lifting rod 10 can be driven to move on the bottom workbench 1, and the second electric lifting rods 9 can drive the first lifting rod 10 to lift and lower.

[0023] As a technical optimization solution of the present invention, on the side walls of the two first lifting rods 10 away from each other, fixing rods 21 are installed near the clamping plates 24. Electric telescopic rods 23 are embedded in the fixing rods 21. The telescopic ends of the electric telescopic rods 23 face the clamping plates 24. The telescopic ends of the electric telescopic rods 23 are installed with positioning rods 22, and one side of the clamping plate 24 close to the positioning rod 22 is movably connected to the positioning rod 22. The electric telescopic rods 23 can drive the two clamping plates 24 to move closer to each other, so as to complete the clamping of the rough blank.

[0024] As a technical optimization solution of the present invention, on the side of the positioning rod 22 close to the clamping plate 24, a sliding groove 35 is opened. A connecting block 36 is slidably installed inside the sliding groove 35. One side of the connecting block 36 close to the clamping plate 24 is connected to the clamping plate 24. At the top and bottom of the inner wall of the sliding groove 35, second pressure sensors 38 are installed. On the side wall of the connecting block 36 close to the second pressure sensor 38, a second spring telescopic rod 37 is installed. One end of the second spring telescopic rod 37 close to the second pressure sensor 38 abuts against the second pressure sensor 38. During the process of clamping the cold-heading completed rough blank by the clamping plate 24, by the way of the connecting block 36 sliding in the sliding groove 35, the second spring telescopic rod 37 can be made to squeeze the second pressure sensor 38. The second pressure sensor 38 transmits the measured pressure value to the background control system. The background control system compares the measured pressure value with the standard pressure value. If the pressure value exceeds the preset pressure value, it can be judged whether the rough blank is stuck in the mold cavities of the upper die head 5 and the lower die set 6.

[0025] As a technical optimization solution of the present invention, an air inlet groove 32 is provided inside the clamping plate 24. A plurality of air outlet holes 33 are uniformly penetrated through the bottom inner wall of the air inlet groove 32, and an air inlet hole 34 is penetrated through the inner wall of the air inlet groove 32 close to one side of the fixed rod 21. When the clamping plate 24 clamps the rough blank at the feeding groove 15, the fan connected to the air inlet hole 34 starts, air enters the air inlet groove 32, then flows outwards from the air outlet holes 33, and blows from above the rough blank to below. Through this operation method, the dust on the outside of the rough blank can be removed, and the rough blank can be cleaned, which can prevent the dust attached to the rough blank from polluting the inside of the upper die head 5 and the lower die set 6; When the clamping plate 24 clamps the rough blank during the cold heading process of the upper die head 5 and the lower die set 6, by blowing air outwards through the air outlet holes 33, the auxiliary cooling of the rough blank and the lower die set 6 can be realized.

[0026] As a technical optimization solution of the present invention, the detection mechanism includes an auxiliary block 19 and an abutting block 20. A plurality of auxiliary blocks 19 are movably provided on both sides of the top of the lower die set 6. An abutting block 20 is movably installed on one side of the auxiliary block 19 close to the center direction of the lower die set 6. A plurality of rotating rollers 26 are evenly rotatably installed on the side of the abutting block 20 away from the auxiliary block 19. When the rough blank moves upwards after the cold heading in the die cavity of the lower die set 6 is completed, through the sliding of the displacement electric slider 18 in the displacement chute 17, the two auxiliary blocks 19 move towards each other until the rotating rollers 26 on the two abutting blocks 20 abut against the outside of the rough blank. Then, during the rising process of the rough blank, the rotating rollers 26 roll while abutting against the outside of the rough blank. If the rough blank cracks and expands during the cold heading process, then the abutting block 20 will be squeezed by the deformed part of the rough blank and slide into the inside of the first slot 27, and the first spring telescopic rod 31 will squeeze the first pressure sensor 30. The first pressure sensor 30 transmits the detected pressure value to the background control system and compares it with the standard pressure value. If the detected pressure value exceeds the standard pressure value, it means that the rough blank deforms in this production step.

[0027] As a technical optimization solution of the present invention, a first slot 27 is provided on one side of the auxiliary block 19 close to the center direction of the lower die set 6. A telescopic block 25 is slidably installed inside the first slot 27. One side of the telescopic block 25 close to the abutting block 20 is connected to the abutting block 20. The bottom end of the inner wall of the first slot 27 is installed with a first pressure sensor 30. One side of the telescopic block 25 close to the first pressure sensor 30 is installed with a first spring telescopic rod 31. One end of the first spring telescopic rod 31 close to the first pressure sensor 30 abuts against the first pressure sensor 30. Through the sliding of the telescopic block 25 in the first slot 27, the first spring telescopic rod 31 and the first pressure sensor 30 are squeezed, thereby completing the corresponding detection of the rough blank.

[0028] As a technical optimization solution of the present invention, stabilizing sliding grooves 28 are provided on both sides of the inner wall of the first slot 27. A stabilizing slider 29 is slidably installed inside the stabilizing sliding groove 28. One side of the stabilizing slider 29 close to the telescopic block 25 is connected to the telescopic block 25. By sliding the stabilizing slider 29 in the stabilizing sliding groove 28, the sliding stability of the telescopic block 25 in the first slot 27 can be increased.

[0029] As a technical optimization solution of the present invention, a plurality of first electric lifting rods 7 are evenly installed on the side wall of the bottom workbench 1 close to the waste slot 14. The lifting ends of the first electric lifting rods 7 face upward. A movable plate 8 is installed at the lifting ends of the first electric lifting rods 7. Two second lifting rods 16 are installed on one side of the movable plate 8 close to the lower die set 6. Displacement sliding grooves 17 are provided on the sides of the two second lifting rods 16 close to each other. A displacement electric slider 18 is installed on one side of the auxiliary block 19 close to the displacement sliding groove 17. The displacement electric slider 18 is slidably installed inside the displacement sliding groove 17. By sliding the displacement electric slider 18 in the displacement sliding groove 17, the auxiliary block 19 can be moved on the second lifting rod 16 according to different usage requirements, and the first electric lifting rod 7 can drive the movable plate 8 and the second lifting rod 16 to lift according to different usage requirements.

[0030] When the present invention is in use, the device is for the production and use of alloy tight screws. The electrical equipment used in the device is powered by connecting to an external power supply through wires. The device controls the electrical equipment in the device by presetting a control system. The first pressure sensor 30 and the second pressure sensor 38 used in the device are both existing mature technologies, so no more elaboration will be made on them. The air inlet hole 34 is connected to a preset blower outside the device through a conduit. The upper die head 5 and the lower die set 6 used in the device are both existing mature technologies, so no more elaboration will be made on them. Cavities corresponding to the upper die head 5 are evenly provided on the lower die set 6. The bottom workbench 1 is provided with a loading manipulator below the loading slot 15 for loading the rough blanks to be cold-headed. The loading method is that the manipulator vertically lifts the cut rough blanks from the loading slot 15, which is an existing mature technology, so no more elaboration will be made on it. A blanking device, such as a blanking conveyor belt or a blanking bucket, is provided below the blanking slot 13 and the waste slot 14. The upper die head 5 can pass through between the two first lifting rods 10 and between the two second lifting rods 16 and cooperate with the lower die set 6.

[0031] During the production process of the device, the rough blank to be processed is loaded from the loading chute 15. The loading manipulator clamps the bottom of the rough blank and transports the rough blank upward from the bottom of the loading chute 15. After the rough blank moves to the preset use height, by sliding the moving electric slider 12 in the moving chute 11, the first lifting rod 10 moves in the direction of the loading chute 15. When the first lifting rod 10 moves to the preset use position, the clamping plate 24 at one end of the first lifting rod 10 close to the loading chute 15 moves above the rough blank. Subsequently, the electric telescopic rod 23 drives the clamping plates 24 on the two first lifting rods 10 to move closer to each other, so that the two clamping plates 24 clamp the top of the rough blank. Then, the loading manipulator releases the bottom end of the rough blank. By sliding the moving electric slider 12 in the moving chute 11 and combining the way that the second electric lifting rod 9 drives the first lifting rod 10 to lift and lower, the clamping plate 24 can clamp the rough blank into the first cavity of the lower die set 6. Subsequently, the clamping plates 24 move away from each other to complete the loading of the rough blank into the cavity of the lower die set 6. Then, the first lifting rod 10 moves again to the use position for clamping the loading chute 15. Subsequently, the hydraulic rod 4 drives the lifting plate 3 to move downward, so that the upper die head 5 and the lower die set 6 cooperate to complete the preliminary cold heading of the rough blank; Subsequently, the clamping plates 24 at the loading chute 15 move closer to each other again to complete the clamping of the new rough blank. The clamping plates 24 at the first cavity of the lower die set 6 move closer to each other to complete the clamping of the rough blank after preliminary cold heading. Then, by moving the first lifting rod 10 upward and combining left and right movement and following the above operation steps, the step-by-step loading and movement of the rough blank can be completed. When the cold heading of the rough blank is completed in the last cavity of the lower die set 6, it can be clamped by the clamping plate 24 to the unloading chute 13 for unloading.

[0032] When it is necessary to check whether there is a jamming situation between the rough blank and the cavities in the upper die head 5 and the lower die set 6 during the processing of the rough blank, when the upper die head 5 and the lower die set 6 are separated and lifted to the preset height position, the two clamping plates 24 move closer to each other to complete the clamping of the rough blank. Immediately when the upper die head 5 rises, if there is a jamming situation between the upper die head 5 and the rough blank, at this time, the connecting block 36 will slide upward inside the sliding groove 35 and drive the second spring telescopic rod 37 to squeeze the second pressure sensor 38. The second pressure sensor 38 transmits the measured pressure value to the background control system. The background control system compares the measured pressure value with the standard pressure value. If the pressure value exceeds the preset pressure value, it means that there is a jamming situation between the rough blank and the upper die head 5; When the clamping plate 24 clamps out the rough blank after cold heading from the die cavity of the lower die set 6, if there is a clamping situation between the rough blank and the die cavity of the lower die set 6, the connecting block 36 will slide downward inside the sliding groove 35, driving the second spring telescopic rod 37 to squeeze the second pressure sensor 38. The second pressure sensor 38 transmits the measured pressure value to the background control system. The background control system compares the measured pressure value with the standard pressure value. If the pressure value exceeds the preset pressure value, it indicates that there is a clamping situation between the rough blank and the die cavity of the lower die set 6. When it is detected that there is a clamping situation between the rough blank during processing and the die cavities in the upper die head 5 and the lower die set 6, the staff can immediately detect the upper die head 5 and the lower die set 6 to prevent the upper die head 5 and the lower die set 6 from being damaged more severely during use.

[0033] When the clamping plate 24 clamps the rough blank at the loading chute 15, the fan connected to the air inlet hole 34 starts, and air enters the air inlet groove 32, then flows out from the air outlet hole 33 and blows from above the rough blank to below. Through this operation method, the dust on the outside of the rough blank can be removed, and the rough blank can be cleaned, preventing the dust attached to the rough blank from contaminating the inside of the upper die head 5 and the lower die set 6. When the clamping plate 24 clamps the rough blank during the cold heading process of the upper die head 5 and the lower die set 6, by blowing air out through the air outlet hole 33, the rough blank and the lower die set 6 can be assisted in cooling.

[0034] When the rough blank moves upward after the cold heading in the die cavity of the lower die set 6 is completed, through the sliding of the displacement electric slider 18 in the displacement sliding groove 17, the two auxiliary blocks 19 move closer to each other until the rotating rollers 26 on the two abutting blocks 20 abut against the outside of the rough blank. Then, during the upward movement of the rough blank, the rotating rollers 26 roll while abutting against the outside of the rough blank. If the rough blank cracks and expands during the cold heading process, then the abutting block 20 will be squeezed by the deformed part of the rough blank and slide into the first slot 27, and the first spring telescopic rod 31 will squeeze the first pressure sensor 30. The first pressure sensor 30 transmits the detected pressure value to the background control system and compares it with the standard pressure value. If the detected pressure value exceeds the standard pressure value, it indicates that the rough blank has deformed in this production step. After the deformation of the rough blank is detected, the first electric lifting rod 7 drives the movable plate 8 to move upward until the rough blank is separated from the mold cavity in the lower mold assembly 6. The displacement electric slider 18 slides in the displacement slide groove 17, so that the two abutment blocks 20 are squeezed and abutted against the rough blank. At this time, the top of the abutment block 20 abuts against the bottom end of the screw head after the rough blank is processed. Then the two abutment blocks 20 move toward the waste trough 14. When the rough blank moves to the top of the waste trough 14, the two auxiliary blocks 19 move away from each other, so that the two abutment blocks 20 no longer abut against the rough blank. Then the rough blank can be discharged from the waste trough 14 at this location. This operation method can not only complete the classification and discharge of qualified and unqualified workpieces, but also, by setting up multiple waste troughs 14, the staff can accurately know at which step the rough blank is damaged during processing, so that the equipment can be inspected and repaired more accurately according to the results.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
