Description

Technical Field

[0001] This invention relates to the field of cold heading machine structure, and particularly to a cold heading machine drive mechanism. Background Technology

[0002] Cold heading machines process parts through stamping actions. A conventional cold heading machine is driven by only one motor, which outputs a drive shaft. The drive shaft is connected to a mechanism for cold heading, a swing arm assembly for driving the cutting mechanism, a swing arm assembly for driving the feed, and a swing assembly for retracting the part. In other words, the driving force for all four sets of action mechanisms comes from the drive shaft.

[0003] Although the four sets of actuation mechanisms operate in a coordinated manner, the length required for the swing arm that drives the sample injection to extend to the sample injection side is relatively long. At the same time, the structure of the swing arm that drives the sample injection has a certain degree of complexity due to its multi-stage linkage, which is also an adverse effect from the perspective of installation and debugging. Summary of the Invention

[0004] The main objective of this invention is to provide a cold heading machine drive mechanism, which aims to solve the problem that the structure of the swing arm assembly for driving the cold heading machine has a certain degree of complexity due to its multi-stage linkages, and that its installation and debugging are also difficult.

[0005] To achieve the above objectives, the present invention provides a cold heading machine drive mechanism, comprising:

[0006] Base;

[0007] Supporting the slide groove, connected to the base;

[0008] The main drive shaft assembly includes a main drive shaft and a main drive swing arm fixed to the main drive shaft;

[0009] A sliding assembly includes a base block and an ejector block connected to the base block. The main drive arm drives the sliding assembly to slide along the length of the supporting groove. A drive ramp is provided on the ejector block.

[0010] The cutting component, matched with the sliding component, is driven away from the base block by the driving ramp of the ejector block;

[0011] A driving component is connected to the end of the sliding assembly away from the main driving arm;

[0012] The sample feeding gear assembly includes a sample feeding drive shaft and a sample feeding swing arm connected to the sample feeding drive shaft. The drive member is matched with the sample feeding swing arm, and the drive member drives the swing arm to swing. The sample feeding gear assembly feeds samples when the sample feeding drive shaft rotates in the forward direction, and stops feeding samples when the sample feeding drive shaft rotates in the reverse direction.

[0013] The main drive arm drives the oscillation of the sample feeding arm through the sliding component and the drive component.

[0014] Furthermore, the cold forging machine drive mechanism also includes an elastic component, which is connected to the base or an external fixed structure; the middle part of the sample injection swing arm in the length direction is connected to the sample injection drive shaft, and the two ends of the sample injection swing arm in the length direction are the drive end and the abutment end, respectively. The drive end is connected and matched with the drive component, and the elastic component drives the sample injection drive shaft to rotate in the opposite direction.

[0015] Furthermore, the connection position of the elastic component in the length direction of the abutment end is adjustable.

[0016] Furthermore, the driving component is plate-shaped, and a first driving channel extending along the length direction of the sliding component is provided on the driving component. The sample injection swing arm includes a protrusion disposed at the driving end. The driving component also includes a position limiting component, which is correspondingly connected to the first driving channel and is adjustable at a fixed position within the length square of the first driving channel. The position limiting component extends through the height direction of the first driving channel. When the sample injection swing arm rotates to the highest position, the protrusion is in close contact with or forms a gap fit with the top of the first driving channel. When the driving component reciprocates, the first driving channel drives the sample injection swing arm to swing through the protrusion.

[0017] Furthermore, the sample injection arm includes a protrusion disposed on the driving end, and the driving member is provided with a second driving channel. When the protrusion interacts with the second driving channel, the sample injection arm is driven. When the protrusion contacts the second driving channel at any position, the distance between the protrusion and the sample injection driving shaft is the same.

[0018] Furthermore, the driving component includes a plate base and a plurality of assembly blocks detachably connected to the plate base. When the assembly blocks are connected to the plate base, they form the second driving channel with the plate base.

[0019] Furthermore, the fixed position of the protrusion in the length direction of the drive end is adjustable.

[0020] Furthermore, the protrusion is a rolling wheel.

[0021] Furthermore, the ejector block is detachably connected to the base block.

[0022] Furthermore, the drive unit is connected to the top block.

[0023] The cold heading machine drive mechanism provided by this invention simplifies the structural complexity of the drive component and reduces its size by using the sliding component to power the feed gear assembly. This has a positive impact on the stability of operation and the convenience of maintenance and debugging. The main drive arm drives the movement of the drive component through the sliding component. The movement of the drive component is a simple linear reciprocating motion, and the operation is concise and efficient. Attached Figure Description

[0034] Reference Figures 1 to 6 In one embodiment of the present invention, a cold heading machine drive mechanism includes:

[0035] Base 100;

[0036] Supporting groove 200, connected to the base 100;

[0037] The main drive shaft assembly 300 includes a main drive shaft 310 and a main drive swing arm 320 fixed to the main drive shaft 310.

[0038] The sliding component 400 includes a base block 410 and an ejector block 420 connected to the base block 410. The main drive swing arm 320 drives the sliding component 400 to slide in the length direction of the supporting slide groove 200. The ejector block 420 is provided with a drive inclined surface 421.

[0039] The cutting component 500 is matched with the sliding component 400 and is driven away from the base block 410 by the driving inclined surface 421 of the ejector block 420.

[0040] A drive component 600 is connected to the end of the sliding assembly 400 that is away from the main drive arm 320;

[0041] The sample feeding gear assembly 700 includes a sample feeding drive shaft 710 and a sample feeding swing arm 720 connected to the sample feeding drive shaft 710. The drive member 600 is matched with the sample feeding swing arm 720, and the drive member 600 drives the swing arm 720 to swing. When the sample feeding drive shaft 710 rotates in the forward direction, the sample feeding gear assembly 700 feeds samples. When the sample feeding drive shaft 710 rotates in the reverse direction, the sample feeding gear assembly 700 stops feeding samples.

[0042] The main drive swing arm 320 drives the oscillation of the sample injection swing arm 720 through the sliding component 400 and the drive component 600.

[0043] In the existing technology, cold heading machines achieve the processing of parts through stamping action. A conventional cold heading machine has only one motor as its drive source, which outputs a drive shaft. The drive shaft is connected to a mechanism for cold heading, a swing arm assembly for driving the cutting mechanism, a swing arm assembly for driving the feed, and a swing assembly for retracting the part. In other words, the driving force of all four sets of action mechanisms comes from the drive shaft.

[0044] Although the four sets of actuation mechanisms operate in a coordinated manner, the length required for the swing arm that drives the sample injection to extend to the sample injection side is relatively long. At the same time, the structure of the swing arm that drives the sample injection has a certain degree of complexity due to its multi-stage linkage, which is also an adverse effect from the perspective of installation and debugging.

[0045] In this invention, the main drive shaft assembly 300 is located at the head of the base 100 along its length; the supporting slide 200 is located at the middle of the base 100 along its length, serving as the mounting base for the sliding assembly 400; the feed gear assembly 700 is located at the tail of the base 100 along its length; a part ejection swing plate is also provided at the tail of the base 100 along its length, and the corresponding main drive shaft assembly 300 also extends a part ejection drive swing arm. The sliding assembly 400 reciprocates under the drive of the main drive swing arm 320. Since the cutting assembly 500 is matched with the sliding assembly 400, during the movement of the sliding assembly 400, the ejector block 420 acts on the cutting assembly 500 to complete the cutting action. The swing of the injection arm 720 enables the injection gear assembly 700 to complete the injection action. For example, the injection drive shaft 710 can be connected to a ratchet-type mechanism to achieve unidirectional drive. When the injection drive shaft 710 rotates in the forward direction, the injection gear assembly 700 clamps and pushes the sample. When the injection drive shaft 710 rotates in the reverse direction, the injection gear assembly 700 stops the sample delivery.

[0046] The driving component 600 is connected to the sliding component 400, and it also reciprocates. The driving component 600 is matched with the sample injection arm 720, and its motion is transmitted to the arm 720. The matching between the driving component 600 and the sample injection arm 720 can be a direct movable connection or an indirect linkage connection. For example, the driving component 600 may have a driving channel or a driving protrusion, and the sample injection arm 720 may have a corresponding driving channel or driving protrusion, thus establishing a connection between them. Specifically, when the driving component 600 pushes or pulls the sample injection arm 720, the sample injection drive shaft 710 rotates in the forward direction (in all embodiments of this invention, when the driving component 600 pushes the sample injection arm 720, the sample injection drive shaft 710 rotates in the forward direction).

[0047] In summary, by understanding that the driving component 600 of the sliding assembly 400 provides power to the sample feed gear assembly 700, the structural complexity of the driving component 600 is simplified and the structural size is reduced; this has a positive impact on the stability of operation and the convenience of maintenance and debugging; the main drive swing arm 320 drives the movement of the driving component 600 through the sliding assembly 400, and the movement of the driving component 600 is a simple linear reciprocating motion, with simple and efficient operation.

[0048] Reference Figures 3 to 6 In one embodiment, the cold forging machine drive mechanism further includes an elastic component 800, which is connected to the base 100 or an external fixed structure; the middle part of the sample injection swing arm 720 in the length direction is connected to the sample injection drive shaft 710, and the two ends of the sample injection swing arm 720 in the length direction are the driving end and the abutment end, respectively. The driving end is connected and matched with the driving component 600, and the elastic component 800 drives the sample injection drive shaft 710 to rotate in the opposite direction.

[0049] Whether the drive component 600 pushes or pulls the sample injection swing arm 720, the matching between the drive component 600 and the sample injection swing arm 720 can easily lead to loosening. In this embodiment, the driving direction of the elastic component 800 is the reverse rotation of the sample injection drive shaft 710. Therefore, when the drive component 600 drives the sample injection swing arm 720 to rotate in the forward direction, it overcomes the effect of the elastic component 800, resulting in a better connection between the drive component 600 and the sample injection swing arm 720. After the drive component 600 completes the forward rotation drive of the sample injection swing arm 720, the elastic component 800 can assist the sample injection swing arm 720 in its reset swing, ensuring the precise action of the drive component 600 on the sample injection swing arm 720. The elastic component 800 can be a helical spring, hydraulic rod, or other structures, and it can be mounted on the base 100 or have its own fixed foundation.

[0050] Reference Figures 3 to 6 The connection position of the elastic component 800 in the length direction of the abutment end is adjustable.

[0051] Depending on the specific requirements of the sample injection arm 720, the elastic feedback provided by the elastic component 800 may vary. In this embodiment, the connection position of the elastic component 800 along its length at the supporting end is adjustable. Therefore, as the lever arm of the elastic component 800 changes, the elastic feedback provided by it can also be adjusted. Multiple fixing holes are provided along the length of the supporting end, and the adjustable connection position of the elastic component 800 is achieved by changing the corresponding fixing holes.

[0052] Reference Figures 3 to 4In one embodiment, the driving member 600 is plate-shaped, and a first driving channel 610 extending along the length of the sliding component 400 is provided on the driving member 600. The sample injection swing arm 720 includes a protrusion 721 disposed at the driving end. The driving member 600 also includes a position limiting member 620, which is correspondingly connected to the first driving channel 610 and is adjustable at a fixed position in the rectangular shape of the first driving channel 610. The position limiting member 620 extends through the height direction of the first driving channel 610. When the sample injection swing arm 720 rotates to the highest position, the protrusion 721 is in close contact with or forms a gap fit with the top of the first driving channel 610. When the driving member 600 reciprocates, the first driving channel 610 drives the sample injection swing arm 720 to swing through the protrusion 721.

[0053] Since the extension direction of the first driving channel 610 is consistent with the length direction of the sliding component 400, the sample injection swing arm 720 will not be driven to swing when the protrusion 721 slides in the first driving channel 610. Only when the protrusion 721 abuts against the position limiting member 620 does the basis for driving the sample injection swing arm 720 to swing exist. Therefore, by adjusting the fixed position of the position limiting member 620 on the first driving channel 610, the rotation angle of the sample injection swing arm 720 by the driving component 600 can be changed accordingly. The first driving channel 610 can be a through-type or non-through-type groove structure extending through the thickness direction of the driving component 600. In this embodiment, the first driving channel 610 is a through structure, so the interaction between the driving member 600 and the protrusion 721 can be observed; and the fixation of the first driving channel 610 is limited so as not to interfere with the rotation of the sample injection swing arm 720; the driving member 600 is provided with a second fixing groove 611 at the top of the first driving channel 610, and the position limiting member 620 is fixed to the second fixing groove 611 by bolts, thereby realizing the adjustable fixed position.

[0054] Reference Figures 5 to 6 In one embodiment, the sample injection swing arm 720 includes a protrusion 721 disposed on the drive end, and the drive member 600 is provided with a second drive channel 630. When the protrusion 721 interacts with the second drive channel 630, the sample injection swing arm 720 is driven. When the protrusion 721 contacts the second drive channel 630 at any position, the distance between the protrusion 721 and the sample injection drive shaft 710 is the same.

[0055] In this embodiment, when the protrusion 721 contacts any position of the second drive channel 630, the distance between the protrusion 721 and the sample feeding drive shaft 710 is the same. Therefore, the shape of the second drive channel 630 needs to be arc-shaped. The arc-shaped second drive channel 630 enables the drive member 600 to stably push the sample feeding arm 720, thus making the sample feeding process of the sample feeding gear assembly 700 more stable. In this embodiment, due to the specific curvature of the second drive channel 630, the drive member 600 may need to be replaced accordingly after changing the product model.

[0056] Reference Figures 3 to 4 In one embodiment, the drive unit 600 includes a plate base 640 and a plurality of assembly blocks 650 detachably connected to the plate base 640. When the assembly blocks 650 are connected to the plate base 640, they form the second drive channel 630 with the plate base 640.

[0057] In this embodiment, by combining different models of assembly blocks 650, a second drive channel 630 can be formed without replacing the entire drive component 600, reducing the difficulty of maintenance and debugging. Similarly, the material of the assembly blocks 650 can be different from that of the substrate 640, using a higher strength and superior performance option. The stacking direction of the assembly blocks 650 can be horizontal or vertical, and the connection method between the assembly blocks 650 and the substrate 640 can be bolted or snap-fitted.

[0058] In one implementation, the protrusion 721 is adjustable in a fixed position along the length of the drive end.

[0059] Since the reciprocating stroke of the drive component 600 is fixed, and the sample feeding length of different product models may vary, changing the mating position between the drive component 600 and the sample feeding swing arm 720 can achieve the rotation angle of the sample feeding swing arm 720, thereby changing the sample feeding size of the sample feeding gear assembly 700. In this embodiment, the drive end has a hollowed-out second fixing slot along its length, and the protrusion 721 is connected to the second fixing slot by a bolt assembly, thereby enabling adjustment of the fixed position.

[0060] Reference Figures 3 to 4 In one implementation, the protrusion 721 is a rolling wheel.

[0061] The frictional force of the rolling wheel moving in the drive channel is then transformed into rolling friction, making the driving process of the drive component 600 smoother.

[0062] Reference Figures 3 to 4 In one implementation, the ejector block 420 is detachably connected to the base block 410.

[0063] In this embodiment, the base block 410 serves as a fixed foundation. To address different usage environments, the ejector block 420 is fixed at a corresponding position on the base block 410. This eliminates the need to replace the base block 410 when changing product models. Furthermore, the ejector block 420 and the cutting assembly 500 have multiple functions and a high replacement frequency; therefore, the separate structure of the ejector block 420 and the base block 410 also mitigates the aforementioned disadvantages.

[0064] Reference Figures 3 to 4 In one implementation, the drive 600 is connected to the ejector block 420.

[0065] When the model of the processed product changes, the sample feeding action of the feed gear assembly 700 needs to be changed, and the operation of the drive component 600 also needs to be adjusted. Similarly, the need to replace the cutting assembly 500 is more pronounced when the product model changes, and the ejector block 420 controlling the cutting assembly 500 may also need to be replaced. Therefore, in this embodiment, the drive component 600 and ejector block 420 can be combined, with one drive component 600 and ejector block 420 per product model, allowing for a unified replacement of the entire structure. The drive component 600 and ejector block 420 can be either separate or integrated structures.

[0066] In summary, the cold heading machine drive mechanism provided by the present invention, by understanding that the driving component 600 of the sliding component 400 provides power to the sample feeding gear assembly 700, simplifies the structural complexity of the driving component 600 and reduces its structural size; it has a beneficial effect on the stability of operation and the convenience of maintenance and debugging; the main drive swing arm 320 drives the movement of the driving component 600 through the sliding component 400, and the movement of the driving component 600 is a simple linear reciprocating motion, with concise and efficient operation.
