Description

Technical Field

[0001] The present invention relates to the technical field of forming equipment, and particularly relates to a hot forging forming equipment for processing hardware fasteners and a using method thereof. Background Art

[0002] The hot forging forming process is a common metal processing process. It is a process of heating metal materials to a certain temperature and then pressing them into the required shape by using pressure. This process has the advantages of high efficiency, high precision, and low cost. The principle of the hot forging forming process is to utilize the plastic deformation characteristics of metal materials at high temperatures and achieve shape change through pressing. In the hot forging forming process, first, the metal material needs to be heated to a certain temperature. Generally, the heating temperature is above the recrystallization temperature of the material. Then, the heated metal material is placed in a mold, and a certain pressure is applied to make it plastically deform in the mold, and finally, a part with the required shape is obtained. In the production process of hardware fasteners, the hot forging forming technology is usually adopted to integrally form the hardware fasteners.

[0003] In the existing fastener hot forging forming equipment, during use, workers need to manually take out the formed fasteners with tools. It is easily affected by high temperature during taking out, and the practicability is low. Moreover, due to the extrusion forming of the fasteners, the fasteners are tightly clamped with the die base, making it difficult for the formed parts to discharge and easily causing wear.

The upper die base is placed on the upper side of the lower die base, and the material storage shell is also connected to the support plate.

[0020] The present invention also discloses a usage method of a hot forging forming device for processing hardware fasteners, including the following steps:

[0021] S1: Place the workpiece to be processed and formed between the two split die seats of the lower die seat, and the workpiece falls into the forming groove;

[0022] S2: Control the operation of the displacement oil cylinder. The piston rod of the displacement oil cylinder drives the extrusion block to move upward. When the extrusion block moves upward, it extrudes the extrusion inclined surface of the force-bearing block, and the force-bearing block drives the split die seat to move away from the inner wall of the machine base, and the two split die seats of the lower die seat abut against each other;

[0023] S3: Subsequently, control the operation of the downward pressure oil cylinder. The piston rod of the downward pressure oil cylinder drives the moving plate to move downward. The moving plate drives the upper die seat to move downward through the connecting rod, and then extrudes and forms the workpiece in the forming groove of the lower die seat. Then, control the downward pressure oil cylinder to drive the moving plate to move upward, so that the upper die seat moves away from the lower die seat;

[0024] S4: Subsequently, control the operation of the displacement oil cylinder, so that the piston rod of the displacement oil cylinder drives the extrusion block to move downward, so that the extrusion block no longer abuts against the force-bearing block, and the two split die seats of the lower die seat move away from each other under the pulling of the first elastic telescopic rod;

[0025] S5: When the extrusion block moves downward, it drives the first toothed plate to mesh and drive with the movable gear. The movable gear meshes and drives with the second toothed plate. The second toothed plate drives the lifting block to move upward through the lifting plate, so that the lifting block pushes up the formed workpiece placed in the forming groove when the two split die seats are separated;

[0026] When the movable gear rotates, it drives the screw rod to rotate. The sleeve moves axially along the screw rod. The sleeve drives the pushing seat to displace through the connecting plate and the second elastic telescopic rod, so that the pushing seat moves towards the blanking groove. Before the formed workpiece is pushed out of the forming groove by the lifting block, the pushing seat abuts against the formed workpiece, and the second elastic telescopic rod is compressed. After the formed workpiece moves out of the forming groove, the second elastic telescopic rod recovers and pushes the formed workpiece to move to the blanking groove. After the formed workpiece enters the blanking groove, it slides out from the discharge groove along the blanking plate. And when the receiving groove of the pushing seat moves above the forming groove, the workpiece to be processed in the receiving groove automatically falls into the forming groove, realizing the blanking of the formed workpiece and the loading of the workpiece to be processed;

[0027] S6: Subsequently, repeat step S2, control the operation of the displacement oil cylinder, so that the two split die seats of the lower die seat approach and abut against each other. And in this process, the screw rod rotates reversely, so that the pushing seat resets and moves back. After the receiving groove of the pushing seat moves to the bottom of the storage shell, the workpiece to be processed in the storage shell automatically falls into the receiving groove, preparing for the subsequent extrusion and forming of the workpiece. Then repeat S3 - S5 to realize the continuous processing and forming of multiple workpieces in the storage shell.

[0028] Compared with the prior art, the present invention provides a hot forging forming device for processing hardware fasteners and its usage method, having the following beneficial effects:

[0029] 1. The hot upset forming equipment for processing hardware fasteners and its usage method can drive the lifting component to act when the displacement component works, and drive the material pushing component to act when the lifting component works, enabling automatic blanking of the formed workpieces and automatic feeding of the workpieces to be processed, preventing the staff from being affected by high temperature when using tools for loading and unloading, and the workpiece loading and unloading are carried out synchronously, effectively improving the processing efficiency of the hardware fastener workpieces and enhancing the safety of the operation.

[0030] 2. The hot upset forming equipment for processing hardware fasteners and its usage method control the operation of the displacement oil cylinder, so that the piston rod of the displacement oil cylinder drives the extrusion block to move downward, making the extrusion block no longer abut against the stress block. The two split die seats of the lower die seat move away from each other under the pulling of the first elastic telescopic rod, reducing the connection tightness between the lower die seat and the formed workpiece, thereby reducing the blanking difficulty of the formed workpiece and avoiding damage to the formed workpiece during blanking.

[0031] 3. The hot upset forming equipment for processing hardware fasteners and its usage method are provided with a blanking plate inclined in the blanking groove, which facilitates the automatic sliding discharge of multiple extruded and formed workpieces after entering the blanking groove, reducing the workload and working difficulty of the staff.

[0032] 4. The hot upset forming equipment for processing hardware fasteners and its usage method are provided with elastic telescopic plates on the upper side of the blanking groove. The two elastic telescopic plates cooperate to guide and limit the formed workpieces pushed by the material pushing seat, enabling the material pushing seat to smoothly push the formed workpieces into the blanking groove and ensuring the orderly progress of the blanking work.

[0033] 5. The hot upset forming equipment for processing hardware fasteners and its usage method drive the material pushing seat to displace when the material pushing component works. The baffle plate arranged on the material pushing seat can block the bottom opening of the storage shell to prevent the workpieces to be processed in the storage shell from falling. When the material pushing seat returns and moves back, after the material receiving groove of the material pushing seat moves to the bottom of the storage shell, the workpieces to be processed in the storage shell automatically fall into the material receiving groove, preparing for the subsequent extrusion forming of the workpieces, realizing automatic replenishment of the workpieces, reducing the workload of the staff, and improving the forming efficiency of the workpiece processing.

[0048] Embodiment 1: Refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , a hot forging forming device for processing hardware fasteners, including a machine base 1, and further including:

[0049] A lower die base 2, multiple lower die bases 2 are provided and are slidably arranged on the machine base 1 at equal intervals. Each lower die base 2 includes two split die bases 201 with the same structure. The two split die bases 201 are provided with mating forming grooves. A first elastic telescopic rod 202 is arranged between the split die base 201 and the inner wall of the machine base 1;

[0050] A displacement lifting mechanism, which includes a displacement component arranged on the machine base 1 for driving the separation of the two split die bases 201 and a lifting component for ejecting the formed workpiece in the forming groove;

[0051] A material storage shell 3, multiple material storage shells 3 are provided and correspond to the lower die bases 2 one by one. The material storage shell 3 is fixedly arranged on the top of the machine base 1 through a connecting rod. A material pushing component is arranged between the bottom of the material storage shell 3 and the top of the machine base 1. The material pushing component is connected to the displacement lifting mechanism; and

[0052] A pressing part 4, which is arranged on the upper side of the machine base 1 and is used for pressing the workpiece in the lower die base 2;

[0053] Wherein, a blanking groove 5 is opened on one side of the machine base 1 away from the material storage shell 3, and a blanking plate 501 is arranged in the blanking groove 5.

[0054] Specifically, the workpiece to be processed and formed is placed between the two split die bases 201 of the lower die base 2. The workpiece falls into the forming groove. Control the displacement lifting mechanism to work. When the displacement component works, the two split die bases 201 of the lower die base 2 approach each other and abut. Subsequently, control the pressing part 4 to extrude and form the workpiece in the forming groove. Then the displacement component continues to act, and the two split die bases 201 of the lower die base 2 are pulled away from each other by the first elastic telescopic rod 202, reducing the connection tightness between the lower die base 2 and the formed workpiece, thereby reducing the blanking difficulty of the formed workpiece. When the displacement component works, it drives the lifting component to act, and when the lifting component works, it drives the material pushing component to act, realizing the automatic blanking of the formed workpiece and the automatic feeding of the workpiece to be processed, preventing the staff from being affected by high temperature when using tools for loading and unloading, and the workpiece loading and unloading are carried out synchronously, effectively improving the processing efficiency of the hardware fastener workpiece and improving the safety of the operation.

[0055] Example 2: Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , a hot forging forming device for processing hardware fasteners. On the basis of Example 1, further, the displacement component includes a displacement oil cylinder 6 fixed on the machine base 1, an extrusion block 601 connected to the piston rod of the displacement oil cylinder 6, and a force receiving block 602 fixed on the split die base 201. The extrusion block 601 and the force receiving block 602 are provided with matching extrusion inclined surfaces, and one side of the extrusion block 601 away from the force receiving block 602 is movably abutted against the inner wall of the machine base 1.

[0056] Specifically, when the displacement component works, the piston rod of the displacement oil cylinder 6 drives the extrusion block 601 to move upward. When the extrusion block 601 moves upward, it extrudes the extrusion inclined surface of the force receiving block 602, and the force receiving block 602 drives the split die base 201 away from the inner wall of the machine base 1. The two split die bases 201 of the lower die base 2 abut against each other. At this time, both sides of the extrusion block 601 are respectively abutted against the force receiving block 602 and the inner wall of the machine base 1, improving the fixing stability of the split die base 201 and preventing the split die base 201 from loosening when the pressing part 4 extrudes the workpiece in the lower die base 2; after the workpiece in the forming groove is extruded and formed, control the displacement oil cylinder 6 to operate, so that the piston rod of the displacement oil cylinder 6 drives the extrusion block 601 to move downward, so that the extrusion block 601 no longer abuts against the force receiving block 602, and the two split die bases 201 of the lower die base 2 are pulled away from each other by the first elastic telescopic rod 202, reducing the connection tightness between the lower die base 2 and the formed workpiece, thereby reducing the blanking difficulty of the formed workpiece and preventing the formed workpiece from being damaged during blanking.

[0057] Example 3: Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7, Figure 8 and Figure 9 , a hot upsetting forming device for processing hardware fasteners. On the basis of Embodiment 2, further, the jacking assembly includes a support plate 7 fixed on the inner wall of the machine base 1, a screw rod 701 rotatably connected to the support plate 7, a movable gear 702 fixedly connected to the screw rod 701, a first toothed plate 6011 arranged on the extrusion block 601 and meshing with the movable gear 702, a second toothed plate 703 meshingly connected to the side of the movable gear 702 away from the first toothed plate 6011, a lifting plate 704 fixedly connected to the second toothed plate 703, and a jacking block 705 fixedly arranged on the lifting plate 704.

[0058] Further, a guide rod 8 is fixedly arranged on the inner wall of the machine base 1, and the lifting plate 704 is slidably connected to the guide rod 8.

[0059] Specifically, after the workpiece in the forming groove is extruded and formed, the displacement oil cylinder 6 is controlled to operate, so that the piston rod of the displacement oil cylinder 6 drives the extrusion block 601 to move downward, so that the extrusion block 601 no longer abuts against the force-receiving block 602. The two split die bases 201 of the lower die base 2 move away from each other under the pulling of the first elastic telescopic rod 202. When the extrusion block 601 moves downward, it drives the first toothed plate 6011 to mesh and drive with the movable gear 702. The movable gear 702 meshes and drives with the second toothed plate 703. The second toothed plate 703 drives the jacking block 705 to move upward through the lifting plate 704. The lifting plate 704 displaces along the guide rod 8, so that the jacking block 705 pushes up the formed workpiece placed in the forming groove when the two split die bases 201 are separated, facilitating the automatic discharging of the formed workpiece, and the operation is simple.

[0060] Embodiment 4: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 10 , a hot upsetting forming device for processing hardware fasteners. On the basis of Embodiment 3, further, the pushing component includes a sleeve 9 threadedly connected to the screw rod 701, a connecting plate 901 fixedly connected to the sleeve 9, a second elastic telescopic rod 902 fixedly arranged on the top of the connecting plate 901, and a pushing seat 903 connected to the end of the second elastic telescopic rod 902 away from the connecting plate 901. The pushing seat 903 is movably abutted against the workpiece extruded and formed in the forming groove. A sliding groove 11 for the connecting plate 901 to slide is opened on the machine base 1.

[0061] Further, a receiving groove 9031 is opened on the pushing seat 903. A baffle 9032 for blocking the bottom opening of the storage shell 3 is fixedly arranged on the side of the pushing seat 903 away from the forming groove. A reinforcing rod is obliquely arranged between the baffle 9032 and the pushing seat 903.

[0062] Further, the blanking plate 501 is inclined and arranged in the blanking chute 5, and the machine base 1 is provided with a discharge chute 10 communicating with the blanking chute 5 at the low end of the blanking plate 501.

[0063] Specifically, when the movable gear 702 rotates, it drives the screw rod 701 to rotate. The sleeve 9 moves axially along the screw rod 701. The sleeve 9 drives the pusher seat 903 to displace through the connecting plate 901 and the second elastic telescopic rod 902, so that the pusher seat 903 moves towards the blanking chute 5. The baffle 9032 arranged on the pusher seat 903 can block the bottom opening of the storage shell 3 to prevent the workpieces to be processed in the storage shell 3 from falling. Before the formed workpiece is pushed out of the forming groove by the jacking block 705, the pusher seat 903 abuts against the formed workpiece, and the second elastic telescopic rod 902 is compressed. After the formed workpiece moves out of the forming groove, the second elastic telescopic rod 902 resumes and pushes the formed workpiece to move into the blanking chute 5. After the formed workpiece enters the blanking chute 5, it slides out from the discharge chute 10 along the blanking plate 501. And when the receiving groove 9031 on the pusher seat 903 moves above the forming groove, the workpieces to be processed in the receiving groove 9031 automatically fall into the forming groove, realizing automatic feeding of the workpieces, thereby realizing the blanking of the formed workpieces and the feeding of the workpieces to be processed.

[0064] Example 5: Refer to Figure 5 and Figure 6 A hot forging forming device for processing hardware fasteners. On the basis of Example 4, further, the machine base 1 is fixedly provided with multiple groups of guiding parts on the upper side of the blanking chute 5. Each group of guiding parts includes two cooperating elastic telescopic plates 12, and the side of the elastic telescopic plate 12 far away from the blanking chute 5 extends towards the pusher seat 903.

[0065] Specifically, by arranging the elastic telescopic plates 12 on the upper side of the blanking chute 5, the two elastic telescopic plates 12 cooperate to guide and limit the formed workpiece pushed by the pusher seat 903, so that the pusher seat 903 smoothly pushes the formed workpiece into the blanking chute 5, ensuring the orderly progress of the blanking work and preventing the formed workpiece from skewing during the pushing process.

[0066] Example 6: Refer to Figure 1 、 Figure 3 and Figure 11 A hot forging forming device for processing hardware fasteners. On the basis of Example 5, further, the pressing part 4 includes a support plate 401 fixed on the machine base 1, a pressing oil cylinder 402 fixed on the support plate 401, a moving plate 403 connected to the piston rod of the pressing oil cylinder 402, and an upper die holder 404 connected to the moving plate 403 through a connecting rod. The upper die holder 404 is placed on the upper side of the lower die holder 2, and the storage shell 3 is also connected to the support plate 401.

[0067] Specifically, by controlling the operation of the downward pressing oil cylinder 402, the piston rod of the downward pressing oil cylinder 402 drives the moving plate 403 to move downward. The moving plate 403 drives the upper die holder 404 to move downward through the connecting rod, and then extrudes and forms the workpiece in the forming groove of the lower die holder 2. Then, control the downward pressing oil cylinder 402 to drive the moving plate 403 to move upward, so that the upper die holder 404 moves away from the lower die holder 2, realizing the extrusion forming action of the downward pressing part 4 on the workpiece.

[0068] The present invention also discloses a method for using a hot forging forming device for processing hardware fasteners, including the following steps:

[0069] S1: Place the workpiece to be processed and formed between the two split die seats 201 of the lower die holder 2, and the workpiece falls into the forming groove.

[0070] S2: Control the displacement oil cylinder 6 to operate. The piston rod of the displacement oil cylinder 6 drives the extrusion block 601 to move upward. When the extrusion block 601 moves upward, it extrudes the extrusion inclined surface of the force receiving block 602, and the force receiving block 602 drives the split die seat 201 to move away from the inner wall of the machine base 1, and the two split die seats 201 of the lower die holder 2 are in mutual contact.

[0071] S3: Subsequently, control the downward pressing oil cylinder 402 to operate. The piston rod of the downward pressing oil cylinder 402 drives the moving plate 403 to move downward. The moving plate 403 drives the upper die holder 404 to move downward through the connecting rod, and then extrudes and forms the workpiece in the forming groove of the lower die holder 2. Then, control the downward pressing oil cylinder 402 to drive the moving plate 403 to move upward, so that the upper die holder 404 moves away from the lower die holder 2.

[0072] S4: Subsequently, control the displacement oil cylinder 6 to operate, so that the piston rod of the displacement oil cylinder 6 drives the extrusion block 601 to move downward, so that the extrusion block 601 no longer abuts against the force receiving block 602, and the two split die seats 201 of the lower die holder 2 move away from each other under the pulling of the first elastic telescopic rod 202.

[0073] S5: When the extrusion block 601 moves downward, it drives the first toothed plate 6011 to mesh and drive with the movable gear 702. The movable gear 702 meshes and drives with the second toothed plate 703. The second toothed plate 703 drives the jacking block 705 to move upward through the lifting plate 704, so that the jacking block 705 pushes up the formed workpiece placed in the forming groove when the two split die seats 201 are separated.

[0074] When the movable gear 702 rotates, it drives the screw rod 701 to rotate. The sleeve 9 moves axially along the screw rod 701. The sleeve 9 drives the material pushing seat 903 to displace through the connecting plate 901 and the second elastic telescopic rod 902, so that the material pushing seat 903 moves towards the blanking chute 5. Before the formed workpiece is pushed out of the forming groove by the jacking block 705, the material pushing seat 903 abuts against the formed workpiece, and the second elastic telescopic rod 902 is compressed. After the formed workpiece moves out of the forming groove, the second elastic telescopic rod 902 recovers and pushes the formed workpiece to move to the blanking chute 5. After the formed workpiece enters the blanking chute 5, it slides out from the discharge chute 10 along the blanking plate 501. And when the receiving groove 9031 of the material pushing seat 903 moves above the forming groove, the workpiece to be processed in the receiving groove 9031 automatically falls into the forming groove, realizing the blanking of the formed workpiece and the feeding of the workpiece to be processed;

[0075] S6: Subsequently, repeat step S2 to control the displacement oil cylinder 6 to operate, so that the two split die bases 201 of the lower die base 2 approach and abut against each other. During this process, the screw rod 701 rotates reversely, so that the material pushing seat 903 resets and moves back. After the receiving groove 9031 of the material pushing seat 903 moves to the bottom of the storage shell 3, the workpiece to be processed in the storage shell 3 automatically falls into the receiving groove 9031, preparing for the subsequent extrusion forming of the workpiece. Then repeat S3 - S5 to realize the continuous processing and forming of multiple workpieces in the storage shell 3.

[0076] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

10. A method for using a hot upsetting forming device for processing hardware fasteners according to claim 9, characterized in that, It includes the following steps: S1: The workpiece to be processed and formed is placed between the two split die seats (201) of the lower die base (2), and the workpiece falls into the forming groove. S2: Control the displacement oil cylinder (6) to operate. The piston rod of the displacement oil cylinder (6) drives the extrusion block (601) to move upward. When the extrusion block (601) moves upward, it extrudes the extrusion inclined surface of the force receiving block (602). The force receiving block (602) drives the split die seat (201) away from the inner wall of the machine base (1), and the two split die seats (201) of the lower die base (2) are in mutual contact. S3: Subsequently, control the pressing oil cylinder (402) to operate. The piston rod of the pressing oil cylinder (402) drives the moving plate (403) to move downward. The moving plate (403) drives the upper die base (404) to move downward through the connecting rod, and then extrudes and forms the workpiece in the forming groove of the lower die base (2). Then control the pressing oil cylinder (402) to drive the moving plate (403) to move upward, so that the upper die base (404) is away from the lower die base (2). S4: Subsequently, control the displacement oil cylinder (6) to operate, so that the piston rod of the displacement oil cylinder (6) drives the extrusion block (601) to move downward, so that the extrusion block (601) no longer contacts the force receiving block (602). The two split die seats (201) of the lower die base (2) move away from each other under the pulling of the first elastic telescopic rod (202). When the extrusion block (601) moves downward, it drives the first toothed plate (6011) to mesh and drive with the movable gear (702). The movable gear (702) meshes and drives with the second toothed plate (703). The second toothed plate (703) drives the jacking block (705) to move upward through the lifting plate (704), so that the jacking block (705) pushes up the formed workpiece placed in the forming groove when the two split die seats (201) are separated. When the movable gear (702) rotates, it drives the screw rod (701) to rotate. The sleeve (9) moves axially along the screw rod (701). The sleeve (9) drives the material pushing seat (903) to displace through the connecting plate (901) and the second elastic telescopic rod (902), causing the material pushing seat (903) to move towards the blanking chute (5). Before the formed workpiece is pushed out of the forming groove by the lifting block (705), the material pushing seat (903) abuts against the formed workpiece, and the second elastic telescopic rod (902) is compressed. After the formed workpiece moves out of the forming groove, the second elastic telescopic rod (902) recovers and pushes the formed workpiece to move to the blanking chute (5). After the formed workpiece enters the blanking chute (5), it slides out from the discharge chute (10) along the blanking plate (501). And when the receiving groove (9031) of the material pushing seat (903) moves above the forming groove, the workpiece to be processed in the receiving groove (9031) automatically falls into the forming groove, realizing the blanking of the formed workpiece and the feeding of the workpiece to be processed; S6: Subsequently, repeat step S2 to control the operation of the displacement oil cylinder (6) to make the two split die bases (201) of the lower die base (2) approach and abut against each other. During this process, the screw rod (701) rotates reversely to make the material pushing seat (903) reset and move back. After the receiving groove (9031) of the material pushing seat (903) moves to the bottom of the storage shell (3), the workpiece to be processed in the storage shell (3) automatically falls into the receiving groove (9031), preparing for the subsequent extrusion forming of the workpiece. Then repeat S3 - S5 to realize the continuous processing and forming of multiple workpieces in the storage shell (3).
