Description

Technical Field

[0001] This utility model relates to the field of cold heading technology, specifically to an adjustment mechanism for the front punch of a cold heading machine. Background Technology

[0002] A cold heading machine is a specialized piece of equipment used for cold working of metals. It primarily works by applying high pressure to metal materials at room temperature, causing them to undergo plastic deformation within a mold, thereby forming the desired shape and size. The cold heading process is widely used in the production of fasteners such as bolts, nuts, screws, and pins, as well as other small metal parts.

[0003] In cold heading, the front punch is usually located at the front of the die and is responsible for the initial shaping of the metal material or guiding the material into the die. Its working principle is to push the metal material under high pressure, causing it to deform according to a predetermined shape. When processing metal materials of different sizes, it is necessary to adjust the position of the front punch on the cold heading machine to ensure that the front punch can correctly apply impact or extrusion to the metal material. In the existing technology, if the position of the front punch needs to be adjusted, the operator must use tools to loosen the connection between the front punch and the cold heading machine, then adjust the position of the front punch according to the specific size of the metal material, and finally use tools to fix the front punch on the cold heading machine again. This working method is cumbersome and reduces work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustment mechanism for the front punch of a cold heading machine, in view of the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: An adjustment mechanism for the front punch of a cold heading machine is provided, used to adjust the position of the front punch on the cold heading machine. The adjustment mechanism includes:

[0006] Support platform;

[0007] A pushing assembly has a pushing member and a rotating seat. The pushing member passes through the rotating seat and is movably inserted into the support platform. The pushing member is threadedly connected to the rotating seat. The pushing member can rise and fall relative to the support platform as the rotating seat rotates.

[0008] The pusher is provided with an inclined surface, and the front punch is connected to the inclined surface in a transmission manner. The inclined surface can push the front punch to move as the pusher rises and falls relative to the support platform.

[0009] A drive assembly having a rotatable component that is pultrusively connected to the rotating seat.

[0010] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, the rotating base is provided with a through hole, the pushing member is provided with a connecting part, the inner wall of the through hole is provided with an internal thread, the connecting part is provided with an external thread, and the pushing member is threadedly connected to the rotating base through the connecting part.

[0011] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, a first gear is provided on the outer wall of the rotating seat, and a second gear is provided on the rotating component, wherein the first gear meshes with the second gear.

[0012] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, a rotating cap is also provided on the rotating component, and the rotating cap is located above the second gear.

[0013] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, the drive assembly further includes:

[0014] A first support base, wherein the rotating component is movably mounted on the first support base;

[0015] A counter is mounted on the first support base, and one end of the rotating member passes through the support base and is inserted into the counter.

[0016] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, a locking component is also provided on the support platform. The locking component is movably engaged with the first gear to provide fixation for the rotating seat.

[0017] In the aforementioned adjustment mechanism for the front punch of a cold heading machine, the locking assembly includes:

[0018] The second support is located on the side of the rotating seat;

[0019] A locking member passes through the second support base and is movably inserted into the support platform. The locking member is provided with a push part and a snap-fit ​​part located below the push part. The snap-fit ​​part is movably snap-fitted with the first gear.

[0020] An elastic element is sleeved on the locking element and located inside the support platform. One end of the elastic element abuts against the support platform, and the other end abuts against the snap-fit ​​portion.

[0021] Compared with the prior art, the advantages of this utility model are that by manually rotating the rotating component, the rotating seat connected to the rotating component is driven to rotate. Since the rotating seat and the pushing component are connected by a thread, the rotation of the rotating seat will cause the pushing component to move up and down relative to the support platform. The pushing component is designed with an inclined surface, which forms an effective transmission connection with the front punch. Therefore, when the pushing component moves up and down due to the rotation of the rotating seat, the inclined surface will correspondingly push the front punch to move along the preset direction, thereby realizing the adjustment of the position of the front punch. In this process, the operator only needs to manually rotate the rotating component to easily complete the positioning adjustment of the front punch. This process not only does not require any additional tools, but also greatly simplifies the operation process and significantly improves production efficiency. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 4 As shown, this utility model discloses an adjustment mechanism for a front punch of a cold heading machine, used to adjust the position of the front punch on the cold heading machine. The adjustment mechanism includes: a support platform 1; a pushing assembly 2, which has a pushing member 3 and a rotating seat 4. The pushing member 3 passes through the rotating seat 4 and is movably inserted into the support platform 1, and the pushing member 3 is threadedly connected to the rotating seat 4. The pushing member 3 can rise and fall relative to the support platform 1 due to the rotation of the rotating seat 4; an inclined surface 5 is provided on the pushing member 3, and the front punch is drivenly connected to the inclined surface 5. The inclined surface 5 can push the front punch to move due to the rise and fall of the pushing member 3 relative to the support platform 1; and a driving assembly 6, which has a rotating member 7 rotatably disposed, and the rotating member 7 is drivenly connected to the rotating seat 4.

[0029] The support platform 1 is fixed on the cold heading machine. The inclined surface 5 on the pusher 3 is located inside the cold heading machine and is connected to the front punch through a transmission, thus pushing it to move. When it is necessary to adjust the position of the front punch on the cold heading machine, the operator only needs to manually rotate the rotating part 7. This will drive the rotating seat 4 to rotate through the transmission connection. Since the rotating seat 4 and the pusher 3 are connected by a thread, the rotation of the rotating seat 4 will cause the pusher 3 to move up and down relative to the support platform 1. An effective transmission connection is formed between the inclined surface 5 on the pusher 3 and the front punch. Therefore, when the pusher 3 moves up and down due to the rotation of the rotating seat 4, the inclined surface 5 will correspondingly push the front punch to move along the preset direction, thereby realizing the adjustment of the position of the front punch. In this process, the operator only needs to manually rotate the rotating part 7 to easily complete the positioning adjustment of the front punch. This process not only does not require any additional tools, but also greatly simplifies the operation process and significantly improves production efficiency.

[0030] To achieve a threaded connection between the rotating seat 4 and the pushing member 3, a through hole is provided on the rotating seat 4, while a connecting part 8 is provided on the pushing member 3. Specifically, the inner wall of the through hole is machined with internal threads, and the outer surface of the connecting part 8 is machined with matching external threads. In this way, the pushing member 3 can be threadedly connected to the through hole on the rotating seat 4 through its connecting part 8, thereby ensuring a stable and precise fit between the two. Figure 2 When the rotating seat 4 rotates clockwise, the pushing member 3 will move downward relative to the support table 1 due to the interaction between the internal and external threads. Conversely, when the rotating seat 4 rotates counterclockwise, the pushing member 3 will move upward relative to the support table 1.

[0031] Furthermore, a first gear 9 is provided on the outer wall of the rotating seat 4, and the first gear 9 is integrally formed with the rotating seat 4, while a second gear 10 is provided on the rotating part 7, and the first gear 9 and the second gear 10 mesh.

[0032] Furthermore, a rotating cap 11 is also provided on the rotating component 7, which is located above the second gear 10.

[0033] When it is necessary to adjust the position of the front punch on the cold heading machine, the operator only needs to manually rotate the rotating cap 11 on the rotating part 7, thereby driving the second gear 10 to rotate. The second gear 10 meshes with the first gear 9, so the rotation of the second gear 10 will drive the first gear 9 to rotate synchronously. The rotation of the first gear 9 will further drive the rotating seat 4 to rotate. Since the rotating seat 4 and the pusher 3 are connected by a thread, the rotation of the rotating seat 4 will cause the pusher 3 to move up and down relative to the support table 1. At this time, the inclined surface 5 on the pusher 3 will correspondingly push the front punch to move precisely in the preset direction, thereby achieving precise adjustment of the position of the front punch.

[0034] Furthermore, the drive assembly 6 also includes: a first support base 12, on which the rotating member 7 is movably mounted; and a counter 13, which is mounted on the first support base 12, with one end of the rotating member 7 passing through the support base and inserted into the counter 13. The counter 13 accurately calculates the distance the front punch moves by detecting the angle and number of rotations of the rotating member 7. The reading on the counter 13 can directly display the number of millimeters the front punch moves, thereby helping the operator to achieve precise adjustment of the position of the front punch.

[0035] Furthermore, a locking component 14 is also provided on the support platform 1. The locking component 14 is movably engaged with the first gear 9 to provide fixation for the rotating seat 4. This design not only provides a reliable fixing mechanism, but also ensures flexibility and accuracy when adjusting the position of the front punch. The locking component 14 allows the operator to quickly lock or unlock the rotating seat 4 when needed, avoiding changes in the position of the front punch due to accidental rotation, thereby improving the stability and safety of the processing.

[0036] Furthermore, the locking assembly 14 includes: a second support base 15, which is disposed on the side of the rotating base 4; a locking member 16, which passes through the second support base 15 and is movably inserted into the support platform 1, the locking member 16 is provided with a push part 17 and a snap-fit ​​part 18 located below the push part 17, the snap-fit ​​part 18 being movably snap-fitted with the first gear 9; and an elastic member, which is sleeved on the locking member 16 and located inside the support platform 1, one end of the elastic member abutting against the support platform 1 and the other end abutting against the snap-fit ​​part 18, the elastic member preferably being a spring.

[0037] When it is necessary to adjust the position of the forward punch on the cold heading machine, firstly, manually press the pusher 17 on the locking assembly 14. This will disengage the locking part 18 below the pusher 17 from the first gear 9. As the pusher 17 is pressed, the locking part 18 separates from the first gear 9, the elastic element is compressed, and elastic deformation occurs. Continue to rotate the pusher 17, causing the locking part 18 to rotate relative to the first gear 9, so that it completely leaves the locking position. At this time, the first gear 9 is in the unlocked state, and the rotating seat 4 can rotate freely. The rotating part 7 can then be manually rotated to drive the rotating seat. 4. Rotate to begin adjusting the position of the front punch on the cold heading machine; after the front punch is adjusted, manually rotate the push button 17 to return the locking part 18 to the position of engaging with the first gear 9. As the push button 17 rotates, the locking part 18 gradually approaches the first gear 9, the elastic element returns to its original state, one end abuts against the support table 1, and the other end abuts against the locking part 18, providing fixation for the locking part 16. At the same time, the locking part 18 re-engages with the first gear 9, the first gear 9 is fixed, and the rotating seat 4 is also fixed, ensuring that the front punch remains stable during processing.
