Description

Technical Field

[0001] This utility model relates to the field of bolt processing equipment technology, and in particular to a bolt cold heading processing fixture. Background Technology

[0002] In the field of machinery manufacturing, bolts are a widely used fastener, and their production and processing technology directly affects product quality and production efficiency. Cold heading is one of the steps in bolt manufacturing. This process applies pressure to metal materials at room temperature, causing the materials to undergo plastic deformation, thereby forming a bolt head of a specific shape at the end of the bolt body. Compared with hot working processes, cold heading has the advantages of high material utilization, fast production efficiency, and excellent bolt mechanical properties. Therefore, it is widely used in industries such as automobiles, machinery, and construction.

[0003] However, in actual production, ensuring the rapid and stable loading and positioning of bolts, and achieving high efficiency and low error rate during cold heading, has always been a technical challenge. The problem is that traditional tooling cannot simultaneously achieve stability in loading, adaptability to processing, and ease of operation, which can easily lead to bolts getting stuck or shifting before cold heading, thus affecting processing accuracy and efficiency. Therefore, there is an urgent need for a bolt cold heading tooling to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a bolt cold heading tooling, which solves the technical problem that the bolt body is easily stuck or displaced before cold heading in existing processing equipment, thus affecting the processing accuracy and efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A bolt cold heading fixture for cold heading a bolt head from the end of a bolt body, the bolt head extending radially along the bolt body, comprising: a frame, wherein the frame is provided with:

[0007] The feeding assembly includes a material preparation component and a material conveying component, wherein the material preparation component and the material conveying component are arranged sequentially in the X direction;

[0008] A material seat assembly that is movable and adjustable in the X direction, the material seat assembly having a cavity with a side opening for accommodating the bolt body;

[0009] A pushing component is used to push the bolts on the conveying component sequentially from the side opening of the cavity into the cavity;

[0010] A cold heading assembly, comprising: a cold heading punch and a pair of stamping seats that are openable and closable in the Y direction, the cold heading punch being disposed opposite the stamping seats;

[0011] The material discharge port is used to collect the bolt bodies that have been cold-forged.

[0012] Based on the above structure, the principle of the bolt cold heading tooling is as follows: When needed, several bolts are poured into the material preparation component. The material preparation component is activated to organize the disordered bolts and convey them to the conveying component, which then conveys them one by one to the pushing position. Subsequently, the pushing component pushes a single bolt into the cavity of the material holder component. The cavity is used to radially and axially position the bolt to ensure the bolt's position is stable during cold heading and to avoid displacement. Next, the material holder component moves to the cold heading position in the X direction. At this time, a pair of stamping seats close in the Y direction, wrapping around the end of the bolt. The stamping seats press against the bolt. The bolt head is radially constrained at the end, and a pair of openable stamping seats facilitate the entry and exit of the bolt body end, reducing the risk of jamming. Then, the cold heading punch presses down vertically. Under the axial pressure of the cold heading punch and the radial constraint of the pair of stamping seats, the end of the bolt body undergoes plastic deformation and forms a radially extending bolt head. After the bolt head is cold-headed, the cold heading punch retracts and resets, the pair of stamping seats open in the Y direction, and the material seat assembly continues to move in the X direction to bring the cold-headed bolt head to the top of the discharge port. Finally, the cold-headed bolt head falls from the side notch of the cavity into the discharge port, the material seat assembly resets, and one cycle is completed.

[0013] Furthermore, in this application, a bolt cold heading tooling includes a feeding component comprising a linear vibrator and a feeding track. The linear vibrator is mounted on a frame, and the feeding track is detachably mounted on the linear vibrator. The feeding track has a groove of a size adapted to the bolt body, and the groove is arranged along the extension direction of the feeding track. As a preferred embodiment of this application, in this bolt cold heading tooling, the linear vibrator generates vibration force to power the conveying of the bolt body on the feeding track. The groove, sized to fit the bolt body, provides limiting and guiding functions, preventing the bolt body from falling off the feeding track during conveying. The detachable feeding track is mounted on the linear vibrator, facilitating disassembly and replacement when the feeding track is worn or damaged. Furthermore, different specifications of feeding tracks can be used to accommodate bolt bodies of different sizes, improving the tooling's versatility.

[0014] Furthermore, in this application, a bolt cold heading tooling includes a material holder assembly comprising: a mounting base, a material holder, and a first linear drive device. The mounting base is slidably mounted on a frame, and the material holder is detachably mounted on the mounting base. A cavity is disposed on the material holder. The first linear drive device is mounted on the frame, and its drive end is connected to the mounting base. As a preferred embodiment of this application, in this bolt cold heading tooling, the first linear drive device drives the mounting base to move in the X direction, thereby sequentially transferring the bolt body within the cavity between the pushing assembly, the cold heading assembly, and the material drop outlet. The detachable material holder design facilitates replacement with material holders having cavities of different specifications to accommodate bolt bodies of different sizes, improving the tooling's versatility. Furthermore, when the material holder wears out due to long-term use, it can be disassembled and replaced separately, reducing maintenance time and costs.

[0015] Furthermore, in this application, a bolt cold heading tooling is provided, wherein the pushing component includes: an L-shaped top block and a second linear drive device. The L-shaped top block is mounted on the frame at a distance from the material seat in the Y direction. The feeding track is disposed between the L-shaped top block and the material seat. The second linear drive device is mounted on the frame, and the driving end of the second linear drive device is connected to the L-shaped top block. When the bolt body moves to the protrusion facing the L-shaped top block, the L-shaped top block moves in the Y direction to push the bolt body on the feeding component into the cavity. As a preferred embodiment of this application, a bolt cold heading fixture is provided. When the bolt body on the conveying component moves to the protrusion facing the L-shaped top block, the conveying component stops. At this time, the second linear drive device drives the protrusion of the L-shaped top block to extend into the receiving groove in the Y direction. After the protrusion of the L-shaped top block abuts against the bolt body, it continues to move, pushing the bolt body into the cavity. When the L-shaped top block is in contact with the side wall of the feeding track in the Y direction, the bolt body is completely inserted into the cavity, and the L-shaped top block resets. Under the drive of the first linear drive device, the material seat assembly moves the cavity containing the bolt body to the cold heading station, waiting for cold heading processing. At the same time, the feeding track continues to convey the next bolt body to the preset position "facing the protrusion of the top block", preparing for the next pushing cycle.

[0016] Furthermore, in this application, a bolt cold heading tooling is provided, wherein the cold heading assembly further includes: a mounting frame, a third linear drive device, and a floating top block. The mounting frame is mounted on a machine frame, the third linear drive device is mounted on the mounting frame, and the movable end of the third linear drive device is connected to a cold heading punch. The floating top block is mounted on the machine frame. When the material seat moves the bolt body to face the cold heading punch, the floating top block abuts against the material seat. The floating top block covers the side opening of the cavity. A pair of stamping seats are respectively mounted on the material seat and the floating top block. A pressure block is provided at the end of the floating top block away from the second linear drive device. When the pressure block moves up and down vertically, it pushes the floating top block to move away from and closer to the material seat in the Y direction. As a preferred embodiment of this application, a bolt cold heading tooling is provided. A pushing component pushes the bolt body into a cavity. Subsequently, a first linear drive device drives the mounting base to slide the material holder in the X direction, moving the bolt body within the cavity to the cold heading position, i.e., directly opposite the cold heading punch. After the material holder is in place, the pressure block moves vertically downwards, pushing the floating top block closer to the material holder until the floating top block abuts against the side of the material holder, completely covering the side opening of the cavity. Simultaneously, the stamping seat on the material holder mates with the stamping seat on the floating top block, forming a complete forming cavity for the bolt head. After the pair of stamping seats are mated... The third linear drive device starts, and its movable end drives the cold heading punch to move vertically toward the bolt body. The cold heading punch contacts the end of the bolt body and applies axial pressure, forcing the end of the bolt body to undergo plastic deformation in the cavity formed by the two stamping seats, and finally cold heading the bolt head. After cold heading is completed, the third linear drive device drives the cold heading punch to move vertically in the opposite direction, disengage from the bolt body, and reset. The pressure block also begins to reset and moves vertically upward, releasing the thrust on the floating top block. Because the floating top block is floating, under the action of the reset force, the floating top block moves away from the material seat in the Y direction, and the side opening of the cavity reopens, and the cold heading is completed.

[0017] Furthermore, in a bolt cold heading fixture of this application, the mounting frame is provided with a fourth linear drive device. The drive end of the fourth linear drive device is connected to the pressure block. The pressure block is provided with a first inclined surface, and the floating top block is provided with a second inclined surface, the second inclined surface being in contact with the first inclined surface. As a preferred embodiment of this application, in a bolt cold heading fixture, the first inclined surface and the second inclined surface are in contact to form a transmission pair. When the pressure block moves vertically downward, the first inclined surface pushes the second inclined surface, causing the floating top block to move closer to the material seat along the Y direction; conversely, when the pressure block moves upward, the floating top block retracts under the action of a restoring force.

[0018] Furthermore, in a bolt cold heading fixture of this application, a receiving groove is provided on the frame, the receiving groove is installed on the frame, and the receiving groove is connected to the dropping port. As a preferred embodiment of this application, in a bolt cold heading fixture, after the bolt head is cold-headed, a first linear drive device drives the mounting seat to move the material holder away from the cold heading station and above the dropping port. The cold-headed bolt body falls from the cavity into the dropping port, and the material holder continues to reset, ready to receive the next bolt body, entering the next cycle.

[0019] Furthermore, in this application, a bolt cold heading fixture has a frame with a set of casters and an adjustable base at its bottom, the casters and adjustable base being spaced apart along the circumference of the frame. As a preferred embodiment of this application, the casters allow the operator to easily move the fixture within the workshop; the adjustable base allows for height adjustment based on different workshop floor conditions, ensuring the fixture remains level and stable on various surfaces.

[0020] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0021] The purpose of this utility model is to provide a bolt cold heading tooling, which realizes the orderly conveying of bolt bodies by setting up a material preparation component and a material conveying component, improves the adaptability to bolt bodies of different specifications by using a detachable feeding track and material seat, ensures the stable positioning of bolt bodies during cold heading by the cooperation of the cavity and the stamping seat, reduces the risk of material jamming by the openable stamping seat, and improves the efficiency and quality of bolt cold heading by the coordinated operation of various components.

Detailed Implementation

[0028] like Figure 1 , 2 As shown in Figure 3, a bolt cold forging fixture is used to cold forge a bolt head 11 at the end of a bolt body 1, the bolt head 11 extending radially along the bolt body 1, comprising: a frame 2, wherein the frame 2 is provided with:

[0029] The feeding assembly 3 includes a material preparation component 31 and a material conveying component 32, wherein the material preparation component 31 and the material conveying component 32 are arranged sequentially in the X direction;

[0030] The material seat assembly 4 is movable and adjustable in the X direction. The material seat assembly 4 is provided with a cavity 40 with a side opening, which is used to accommodate the bolt body 1.

[0031] Pushing component 5, which is used to push the bolt body 1 on the conveying component 32 sequentially from the side opening of the cavity 40 into the cavity 40;

[0032] The cold heading assembly 6 includes: a cold heading punch 61 and a pair of stamping seats 62 that are openable and closable in the Y direction, wherein the cold heading punch 61 is disposed opposite to the stamping seats 62;

[0033] The material discharge port 7 is used to collect the bolt body 1 after cold forging.

[0034] Based on the above structure, the principle of the bolt cold heading tooling is as follows: When needed, several bolt bodies 1 are poured into the material preparation component 31. The material preparation component 31 is activated to organize the disordered bolt bodies 1 and convey them to the conveying component 32. The conveying component 32 conveys them one by one to the pushing position. Subsequently, the pushing component 5 pushes a single bolt body 1 into the cavity 40 of the material holder component 4. The cavity 40 is used to radially and axially position the bolt body 1 to ensure that the position of the bolt body 1 is stable during cold heading and to avoid displacement. Then, the material holder component 4 moves to the cold heading position in the X direction. At this time, a pair of stamping seats 62 close in the Y direction, wrapping around the end of the bolt body 1. The stamping seats 62 are positioned at the end of the bolt body 1. The bolt body 1 is radially constrained, and a pair of openable stamping seats 62 facilitate the entry and exit of the bolt body 1 end, reducing the risk of jamming. Then, the cold heading punch 61 presses down vertically. Under the axial pressure of the cold heading punch 61 and the radial constraint of the pair of stamping seats 62, the end of the bolt body 1 undergoes plastic deformation, forming a radially extending bolt head 11. After the bolt head 11 is cold-headed, the cold heading punch 61 retracts and resets, the pair of stamping seats 62 open in the Y direction, and the material holder assembly 4 continues to move in the X direction, bringing the cold-headed bolt head 11 to the top of the drop port 7. Finally, the cold-headed bolt head 11 falls from the side notch of the cavity 40 into the drop port 7, the material holder assembly 4 resets, and one cycle is completed. The material preparation component 31 uses a vibratory feeder.

[0035] In this embodiment, the material conveying component 32 includes a linear vibrator 321 and a feeding track 322. The linear vibrator 321 is mounted on the frame 2, and the feeding track 322 is detachably mounted on the linear vibrator 321. The feeding track 322 has a groove 320 of a size adapted to the bolt body 1, and the groove 320 is arranged along the extension direction of the feeding track 322. The linear vibrator 321 generates vibration force to provide power for conveying the bolt body 1 on the feeding track 322. The groove 320, with a size adapted to the bolt body 1, can limit and guide the bolt body 1, preventing it from falling off the feeding track 322 during conveying. The detachable mounting of the feeding track 322 on the linear vibrator 321 facilitates disassembly and replacement when the feeding track 322 is worn or damaged. Furthermore, different specifications of the feeding track 322 can be replaced to accommodate bolt bodies 1 of different specifications, improving the versatility of the tooling. The feed track 322 is detachably mounted on the linear vibrator 321 by screws (not shown).

[0036] In this embodiment, the material holder assembly 4 includes: a mounting base 41, a material holder 42, and a first linear drive device 43. The mounting base 41 is slidably mounted on the frame 2, and the material holder 42 is detachably mounted on the mounting base 41. The cavity 40 is disposed on the material holder 42. The first linear drive device 43 is mounted on the frame 2, and the drive end of the first linear drive device 43 is connected to the mounting base 41. The first linear drive device 43 drives the mounting base 41 to move in the X direction, so as to drive the bolt body 1 in the cavity 40 to be sequentially transferred between the push assembly 5, the cold heading assembly 6, and the material drop port 7. The material holder 42 is detachably designed to facilitate the replacement of material holders 42 with cavities 40 of different specifications to accommodate bolt bodies 1 of different specifications, thereby improving the versatility of the tooling. Furthermore, when the material holder 42 wears out due to long-term use, it can be disassembled and replaced separately, reducing maintenance time and costs. The mounting base 41 is mounted on the frame 2 via a slide rail 44; the material holder 42 is detachably mounted on the mounting base 41 via screws (not shown); and the first linear drive device 43 is a cylinder.

[0037] In this embodiment, the pushing component 5 includes: an L-shaped top block 51 and a second linear drive device 52. The L-shaped top block 51 is installed on the frame 2 at a distance from the material seat 42 in the Y direction. The feeding track 322 is located between the L-shaped top block 51 and the material seat 42. The second linear drive device 52 is installed on the frame 2. The driving end of the second linear drive device 52 is connected to the L-shaped top block 51. When the bolt body 1 moves to the protrusion facing the L-shaped top block 51, the L-shaped top block 51 moves in the Y direction to push the bolt body 1 on the feeding component 32 into the cavity 40. When the bolt body 1 on the conveying component 32 moves to the protrusion facing the L-shaped top block 51, the conveying component 32 stops. At this time, the second linear drive device 52 drives the protrusion of the L-shaped top block 51 to extend into the receiving groove 320 in the Y direction. After the protrusion of the L-shaped top block 51 presses against the bolt body 1, it continues to move, pushing the bolt body 1 into the cavity 40. When the L-shaped top block 51 and the side wall of the feeding track 322 are in contact in the Y direction, the bolt body 1 is completely inserted into the cavity 40, and the L-shaped top block 51 resets. Under the drive of the first linear drive device 43, the material seat assembly 4 moves the cavity 40 containing the bolt body 1 to the cold heading station to wait for cold heading processing. At the same time, the feeding track 322 continues to convey the next bolt body 1 to the preset position "facing the protrusion of the top block", preparing for the next pushing cycle. The second linear drive device 52 is a cylinder.

[0038] In this embodiment, the cold heading assembly 6 further includes: a mounting frame 63, a third linear drive device 64, and a floating top block 65. The mounting frame 63 is mounted on the frame 2, and the third linear drive device 64 is mounted on the mounting frame 63. The movable end of the third linear drive device 64 is connected to the cold heading punch 61. The floating top block 65 is mounted on the frame 2. When the material seat 42 drives the bolt body 1 to move directly opposite the cold heading punch 61, the floating top block 65 abuts against the material seat 42. The floating top block 65 covers the side opening of the cavity 40. A pair of stamping seats 62 are respectively mounted on the material seat 42 and the floating top block 65. The end of the floating top block 65 away from the second linear drive device 52 is provided with a pressure block 66. When the pressure block 66 moves up and down vertically, it pushes the floating top block 65 to move away from and closer to the material seat 42 in the Y direction. The pushing component 5 pushes the bolt body 1 into the cavity 40. Subsequently, the first linear drive device 43 drives the mounting base 41 to slide the material seat 42 in the X direction, moving the bolt body 1 in the cavity 40 to the cold heading position, i.e., the position directly opposite the cold heading punch 61. After the material seat 42 is in place, the pressure block 66 moves vertically downward, pushing the floating top block 65 closer to the material seat 42 until the floating top block 65 abuts against the side of the material seat 42, and the floating top block 65 completely covers the side opening of the cavity 40. At the same time, the stamping seat 62 on the material seat 42 mates with the stamping seat 62 on the floating top block 65 to form a complete forming cavity for the bolt head 11. After the pair of stamping seats 62 are mated, the third linear drive... When device 64 is activated, its movable end drives the cold heading punch 61 to move vertically toward bolt body 1. The cold heading punch 61 contacts the end of bolt body 1 and applies axial pressure, forcing the end of bolt body 1 to undergo plastic deformation in the cavity formed by the two stamping seats 62, ultimately cold heading bolt head 11. After cold heading is completed, the third linear drive device 64 drives the cold heading punch 61 to move vertically in the opposite direction, disengaging from bolt body 1 and resetting. The pressure block 66 also begins to reset, moving vertically upward to release the thrust on the floating top block 65. Because the floating top block 65 is floating, under the action of the reset force, the floating top block 65 moves away from the material seat 42 in the Y direction, and the side opening of the cavity 40 reopens, completing the cold heading. The third linear drive device 64 uses a hydraulic cylinder, and the floating top block 65 is floatingly mounted on the frame 2 by a spring.

[0039] In this embodiment, as Figure 4 , 5As shown, the mounting bracket 63 is equipped with a fourth linear drive device 67. The drive end of the fourth linear drive device 67 is connected to the pressure block 66. The pressure block 66 has a first inclined surface 661, and the floating top block 65 has a second inclined surface 651. The second inclined surface 651 is in contact with the first inclined surface 661. The first inclined surface 661 and the second inclined surface 651 form a transmission pair. When the pressure block 66 moves vertically downward, the first inclined surface 661 pushes the second inclined surface 651, causing the floating top block 65 to move closer to the material seat 42 along the Y direction. Conversely, when the pressure block 66 moves upward, the floating top block 65 retracts under the action of a restoring force. The fourth linear drive device 67 is a cylinder.

[0040] In this embodiment, the frame 2 is provided with a receiving groove 8, which is installed on the frame 2 and is connected to the discharge port 7. After the bolt head 11 is cold-forged, the first linear drive device 43 drives the mounting base 41 to move the material seat 42 away from the cold-forging station and above the discharge port 7. The cold-forged bolt body 1 falls from the cavity 40 into the discharge port 7. The material seat 42 continues to reset, ready to receive the next bolt body 1, and enters the next cycle. The bolt body 1 in the cavity 40 falls into the discharge port 7 through a blower (not shown).

[0041] In this embodiment, the bottom of the frame 2 is provided with a set of casters 91 and a set of adjustable bases 92, which are spaced apart along the circumference of the frame 2. The set of casters 91 allows operators to easily move the tooling within the workshop; the set of adjustable bases 92 is designed to be height-adjustable according to different workshop floor conditions, ensuring that the tooling remains level and stable on various surfaces. There are four casters 91 and four adjustable bases 92.
