Description

Technical Field

[0001] The present invention relates to the technical field of alloy processing, in particular to a forming machine tool for a super-hard alloy toothed disc and a use method thereof. Background Art

[0002] The super-hard alloy chainring forming machine is a special or general processing equipment designed for processing chainring materials with high hardness and high wear resistance.

[0003] When using the super-hard alloy chainring forming machine, the super-hard alloy chainring blank is first fixed, and the appropriate processing method is selected according to the specifications of the chainring, such as stamping and forging, etc. The tooth shape, end face and other parts are processed through the high-precision drive of the machine tool. During the process, the cooling system is used to control the temperature and remove chips in time, and finally a chainring that meets the precision requirements is obtained.

[0019] According to a second aspect of the present invention, there is provided a method for using a super-hard alloy crankset forming machine tool, which is implemented based on a super-hard alloy crankset forming machine tool as described above, and the method comprises the steps of:

[0020] In step 1, a super-hard alloy chainring is placed at the entrance of the slide groove of the trapezoidal seat. The chainring slides downward along the slide groove under the action of gravity. The guide plate in the guide assembly is kept in an inclined state under the elastic force of the first spring, thereby providing preliminary guidance for the chainring. At the same time, the extrusion plate is slightly displaced by the extrusion of the chainring, thereby triggering the start of the transmission assembly.

[0021] In step 2, the chainring continues to slide down the slide groove, and the extrusion plate is completely squeezed into the groove by the chainring, driving the guide plate to rotate around the first fixed axis, driving the extrusion plate to squeeze the transmission bar, and the extruded transmission bar rotates around the second fixed axis, driving the sector gear to rotate, and the sector gear is meshed with the circular gear for transmission, driving the circular gear to rotate around the third fixed axis, and transmitting the rotational power to the pressing plate through the shifting rod;

[0022] Step 3: When the circular gear rotates, the shifting rod rotates synchronously and squeezes the push rod in the energy storage assembly. The push rod rotates around the limit column and stretches the elastic rope, causing the elastic rope to store elastic potential energy. The pressing plate moves to the side of the shifting rod with the push rod, and the second spring on the surface of the transmission bar is stretched, providing power for subsequent reset.

[0023] Step four, when the chainring slides to the entrance of the casting cavity, the elastic potential energy stored in the energy storage assembly is released through the push rod, and the push rod pushes the chainring completely into the casting cavity. After the chainring is cast in the casting cavity, the push rod rises, and the inclined surface of the push rod contacts the chainring formed in the casting cavity, tilting the chainring out of the casting cavity and falling at the outlet of the blanking plate. The ejected chainring slides along the blanking plate through the blanking trough to the collection area.

[0024] The beneficial effects of the present invention are as follows: it effectively eliminates the potential safety hazards of manual observation and operation of loading and unloading materials, avoids safety accidents that may be caused by manual intervention when forging is unstable, and significantly improves the safety of equipment use. At the same time, the continuous guiding, transmission and energy storage pushing functions of the mechanical structure realize the full process automation from material sliding to ejection, reduces manual waiting and operation time, greatly improves the continuity and efficiency of forging production, and ensures the stability of the production process.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it individually or selectively refer to an embodiment that is mutually exclusive of other embodiments.

[0042] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0043] Example 1, with reference to Figures 1-6 、 Figure 10 and Figure 12, which is the first embodiment of the present invention, provides a super-hard alloy crankset forming machine tool, the device includes a box 101; and further includes:

[0044] The feeding structure 200 includes a support base 201 fixed to the surface of the box body 101, a plurality of support columns 202 fixed to the surface of the support base 201, a trapezoidal seat 203 fixed to the surface of the support column 202, a slide 204 opened on the surface of the trapezoidal seat 203, a guide assembly 205 fixed to the side of the slide 204, and a transmission assembly 206 fixed on the guide assembly 205; the support base 201 and the multiple support columns 202 are combined to form a high-stability load-bearing frame to ensure that the trapezoidal seat 203 and the slide 204 can withstand high-frequency impact for a long time without deformation; the trapezoidal seat 203 and the slide 204 structure use the weight of the toothed disc to achieve continuous sliding feeding, eliminating dependence on external power sources.

[0045] The power-assisting structure 300 includes a circular gear 301 movably connected to the transmission assembly 206, a third fixed shaft 302 fixed to the center of the circular gear 301, a lever 303 fixed to the surface of the third fixed shaft 302, an energy storage assembly 304 fixed to the side of the lever 303, and a power-assisting assembly 305 movably connected to the side of the energy storage assembly 304. This automates the chainring pushing process, replacing manual pushing operations, avoiding safety accidents that may be caused by human intervention, and significantly improving the safety of the device.

[0046] The guide assembly 205 includes a groove 2051 defined in the surface of the chute 204, a first fixed shaft 2052 fixedly connected to the surface of the groove 2051, a guide plate 2053 rotatably connected to the surface of the first fixed shaft 2052, an extrusion plate 2054 fixedly connected to one end of the guide plate 2053, and a first spring 2055 fixedly connected to the surface of the extrusion plate 2054, one end of the first spring 2055 being fixedly connected to the surface of the groove 2051. The guide assembly 205 utilizes an elastic guide structure consisting of the guide plate 2053 and the first spring 2055 to achieve adaptive initial guidance of the chainring, ensuring the stability of the chainring's initial sliding. The extrusion plate 2054 is triggered by material extrusion to generate subsequent transmission, forming a guide-trigger linkage and enhancing the proactive responsiveness of the operation.

[0047] The transmission assembly 206 includes a second fixed shaft 2061 fixedly connected to the surface of the groove 2051, a transmission bar 2062 rotatably connected to the surface of the second fixed shaft 2061, a sector gear 2063 fixedly connected to one end of the transmission bar 2062, a recessed groove 2064 defined in the surface of the guide plate 2053, and a retaining groove 2066 defined in the surface of the extrusion plate 2054. Through the mechanical transmission design of the transmission bar 2062 and the sector gear 2063, the displacement of the guide plate 2053 is converted into rotational power, achieving power transmission conversion, providing stable power input to the power-assisting structure 300, and ensuring the reliability of subsequent power-assisting operations.

[0048] A first fixing rod 2065 is fixedly connected to the surface of the concealed groove 2064. A connecting rod 2067, which crosses the limiting groove 2066, is rotatably connected to the surface of the first fixing rod 2065. A second fixing rod 2068 is rotatably connected to the surface of the connecting rod 2067. One end of the second fixing rod 2068 is fixedly connected to the surface of the transmission bar 2062. The linkage design of the connecting rod 2067 spanning the concealed groove 2064 and the limiting groove 2066 closely links the displacement of the guide plate 2053 and the extrusion plate 2054 with the rotation of the transmission bar 2062, forming a mechanical linkage mechanism, ensuring the timeliness and accuracy of the transmission response and improving the efficiency of structural coordination.

[0049] A second spring 2069 is fixedly connected to the surface of the transmission bar 2062. The end of the second spring 2069, which is away from the transmission bar 2062, is fixedly connected to the surface of the groove 2051. The elastic return function of the second spring 2069 automatically resets the transmission bar 2062 after power transmission is completed, preparing for the next transmission operation, maintaining continuous and stable operation of the transmission system, and preventing mechanical jamming.

[0050] During use, after the staff places the super-hard alloy chainring at the entrance of the slide groove 204, the guide plate 2053 remains in an inclined state under the elastic force of the first spring 2055, forming an adaptive preliminary guide for the sliding chainring to ensure the initial sliding stability. The chainring slides down along the inclined slide groove 204 under the action of its own gravity. As the chainring continues to slide, the extrusion plate 2054 is squeezed by the chainring and displaced. This displacement drives the guide plate 2053 to rotate around the first fixed axis 2052. At the same time, the limiting groove 2066 on the surface of the extrusion plate 2054 is linked to the connecting rod 2067 in the hidden groove 2064 of the guide plate 2053. The connecting rod 2067 rotates under the support of the first fixed rod 2065 and passes through the first fixed rod 2065. The second fixed rod 2068 pulls the transmission bar 2062 to rotate around the second fixed axis 2061. When the transmission bar 2062 rotates, the fan gear 2063 at one end of the transmission bar 2062 is driven to rotate and engages with the circular gear 301 of the power-assisting structure 300, converting the displacement of the guide plate 2053 into rotational power and transmitting it to the subsequent power-assisting link. During the rotation of the transmission bar 2062, the second spring 2069 fixed on the surface is stretched, providing an elastic reserve for the automatic reset of the transmission bar 2062 after completing the power transmission. The entire process is achieved through the elastic guide of the guide component 205 and the mechanical linkage of the transmission component 206, thereby realizing a stable connection from the sliding of the chainring to the power transmission, providing reliable power input for subsequent power-assisting operations.

[0051] Example 2, reference Figures 1-9 and Figure 11, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the energy storage component 304 includes a limiting column 3043 fixedly connected to the surface of the groove 2051, a push rod 3042 rotatably connected to the surface of the limiting column 3043, a pressing plate 3041 fixedly connected to the surface of the push rod 3042 and located on the side of the lever 303, and an elastic rope 3044 fixedly connected to the surface of the push rod 3042, and one end of the elastic rope 3044 away from the push rod 3042 is fixedly connected to the surface of the groove 2051. Through the combined design of the limiting column 3043, the push rod 3042, the pressing plate 3041 and the elastic rope 3044, the elastic energy storage characteristics of the elastic rope 3044 are utilized to store energy when the lever 303 rotates and provide a stable pushing force when released. At the same time, the limiting effect of the pressing plate 3041 on the lever 303 prevents mechanical reverse movement, thereby improving the power transmission reliability and operational stability of the power-assisting structure 300. Moreover, the high-speed feeding impact force generated by the explosive release of the elastic rope 3044 causes the alloy to produce a microscopic lattice reorganization effect in the casting cavity 105, thereby improving the fatigue strength of the chainring.

[0052] Compared to Example 1, the assist assembly 305 further comprises a strip groove 3051 defined in the surface of the chute 204, a mounting groove 3052 defined in the surface of the trapezoidal seat 203, a guide rod 3055 movably connected to the surface of the mounting groove 3052, a roller 3054 rotatably connected to the surface of the guide rod 3055, and a rivet 3053 rotatably connected to one end of the guide rod 3055. The movably connected design of the guide rod 3055 and the roller 3054, combined with the layout of the strip groove 3051 and the mounting groove 3052, reduces frictional resistance and ensures smooth guidance when the material slides down through the rotation of the roller 3054. The rivet 3053 connection enhances the connection flexibility of the guide rod 3055.

[0053] Furthermore, a mounting platform 102 is provided on the surface of the box body 101, a fixed base 104 is fixedly connected to the surface of the mounting platform 102, a casting cavity 105 is fixedly connected to the surface of the fixed base 104, a push rod 106 is slidably connected to the center of the casting cavity 105, and one end of the push rod 106 is an inclined surface.

[0054] Furthermore, a chute 401 is formed on the surface of the housing 101, to which a blanking plate 402 is fixedly connected, and a lifting hydraulic component 103 is fixedly connected on the surface of the housing 101. The inclined surface of the ejector pin 106 and the inclined surface of the blanking plate 402 are parallel to each other. The fixed design of the casting cavity 105, the sliding connection of the ejector pin 106, and the inclined surface structure ensure that the formed toothed disc is ejected by the inclined surface and falls at the entrance of the blanking plate 402, and then enters the collection area along the blanking plate 402 and the chute 401. The inclined unloading trajectory formed by the ejection of the inclined surface of the ejector pin 106 can eliminate the hidden danger of microcracks caused by stress concentration during demolding.

[0055] During use, when the circular gear 301 rotates to drive the shift rod 303 to rotate, the shift rod 303 synchronously squeezes the push rod 3042, and the push rod 3042 rotates around the limit column 3043 and stretches the elastic rope 3044, so that the elastic rope 3044 stores elastic potential energy. At the same time, the pressing plate 3041 fixed on the surface of the push rod 3042 moves to the side of the shift rod 303 with the push rod 3042, forming a limit for the shift rod 303 to prevent it from rotating in the opposite direction, thereby ensuring the unidirectional stability of power transmission. When the tooth disc slides to the entrance of the casting cavity 105, the elastic potential energy stored in the elastic rope 3044 is released through the push rod 3042, and the push rod 3042 pushes the tooth disc forward. The disc completely enters the casting cavity 105 to complete the molding. At this time, the lifting hydraulic part 103 rises and the push rod 106 rises at the same time. The working principle of this part is the existing technology, and those skilled in the art can clearly understand it and will not be described here. The inclined surface of the push rod 106 contacts the toothed disc formed in the casting cavity 105, and the guiding effect of the inclined surface is used to tilt the toothed disc to the entrance of the blanking plate 402. The toothed disc slides along the surface of the blanking plate 402 and enters the collection area through the blanking trough 401, effectively eliminating the safety hazards of manual observation and operation of loading and unloading materials, avoiding safety accidents that may be caused by manual intervention when forging is unstable, and significantly improving the safety of equipment use.

[0056] During this process, the guide rod 3055 and the roller 3054 of the power assist assembly 305 are designed to be movably connected. When the chainring slides, they rotate along with the downward movement of the chainring, effectively reducing the friction resistance of sliding and ensuring the smooth sliding of the material.

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3, reference Figures 1-12 This is the third embodiment of the present invention. This embodiment provides a control method for a super-hard alloy crankset forming machine tool. The control method is based on a super-hard alloy crankset forming machine tool in any of the aforementioned embodiments and includes the following steps:

[0059] The first spring 2055 of the guide assembly 205 is used to keep the guide plate 2053 in an inclined state under the elastic force of the first spring 2055, thereby forming an adaptive preliminary guide for the sliding chain plate. When the guide plate 2053 rotates around the first fixed axis 2052, the dark groove 2064 on the surface and the limit groove 2066 on the surface of the extrusion plate 2054 form a mechanical linkage through the connecting rod 2067 to ensure that the angle of the guide plate 2053 is automatically adjusted according to the size of the chain plate, thereby ensuring the initial sliding stability. At the same time, the extrusion plate 2054 is slightly displaced by the extrusion plate 2054. This displacement pulls the transmission bar 2062 to rotate around the second fixed axis 2061 through the connecting rod 2067, and the fan gear 2063 at one end of the transmission bar 2062 rotates accordingly, triggering the transmission assembly 206 to start, realizing the active response of the guide-trigger, and providing the initial conditions for the subsequent power transmission.

[0060] In step 2, the tooth plate continues to slide down the slide groove 204, and the extrusion plate 2054 is continuously squeezed by the tooth plate and gradually moves into the groove 2051, driving the guide plate 2053 to further rotate around the first fixed axis 2052. At this time, the dark groove 2064 on the surface of the guide plate 2053 and the limiting groove 2066 on the surface of the extrusion plate 2054 are closely linked through the connecting rod 2067. The connecting rod 2067 rotates under the support of the first fixed rod 2065 and pulls the transmission bar 2062 to rotate around the second fixed axis 2061 through the second fixed rod 2068. When the transmission bar 2062 rotates, the fan gear 2063 at one end rotates synchronously with it and rotates with the circular gear The tooth surfaces of the transmission bar 2062 are meshed, and the linear displacement of the transmission bar 2062 is converted into the rotational power of the circular gear 301 through gear transmission. During the rotation of the circular gear 301 around the third fixed axis 302, the shifting rod 303 on the surface rotates synchronously with the circular gear 301. The rotation trajectory of the shifting rod 303 is mechanically designed to ensure that it matches the position of the push rod 3042 of the subsequent energy storage component 304, providing a path for the power to be transmitted to the pressing plate 3041. At the same time, the second spring 2069 fixed on the surface of the transmission bar 2062 is stretched due to the rotation of the transmission bar 2062, storing elastic potential energy for the subsequent reset of the transmission bar 2062, thereby ensuring the continuous and stable operation of the transmission system.

[0061] Step three, when the circular gear 301 rotates, the lever 303 on the surface rotates synchronously and gradually approaches the push rod 3042 in the energy storage component 304. When the lever 303 contacts the push rod 3042, the rotational force of the lever 303 pushes the push rod 3042 to rotate around the limit column 3043. During the rotation of the push rod 3042, the elastic rope 3044 fixed at one end is stretched and stores elastic potential energy. The elastic deformation of the elastic rope 3044 provides a stable energy storage mechanism to ensure that the subsequent pushing force is evenly released. At the same time, the pressing plate 3041 fixed on the surface of the push rod 3042 moves to the side of the lever 303 with the push rod 3042. The lever 303 is limited by physical contact to prevent it from rotating in the opposite direction due to inertia or abnormal force, thus ensuring the unidirectional stability of power transmission. At this time, the transmission bar 2062 has been pulled and rotated in step 2, and the second spring 2069 fixed on the surface is continuously in a stretched state, providing elastic reserve for the transmission bar 2062 to automatically reset around the second fixed axis 2061 after completing power transmission, ensuring that the transmission assembly 206 can quickly return to its initial position and prepare for the next round of power transmission. The entire process is achieved through the precise coordination of the mechanical structure, realizing an efficient connection from the sliding of the chainring to the energy storage preparation.

[0062] Step 4: When the chainring slides to the entrance of the casting cavity 105, the push rod 3042 in the energy storage component 304 rotates around the limit column 3043 due to being squeezed by the push rod 303, and the elastic rope 3044 stretched previously begins to release the stored elastic potential energy. The push rod 3042 pushes the chainring forward under the action of the rebound force of the elastic rope 3044 to ensure that it completely enters the casting cavity 105 to complete the molding. After the casting of the chainring is completed, the lifting hydraulic component 103 rises and the push rod 106 rises at the same time, and the inclined surface of the push rod 106 is aligned with the molded part in the casting cavity 105. The chainring contacts the toothed disc and utilizes the guiding effect of the inclined surface to smoothly push the chainring out to the entrance of the blanking plate 402. The surface of the blanking plate 402 is smoothed, and its inclined layout allows the chainring to slide naturally under the action of gravity. At the same time, the guide rod 3055 in the power assist assembly 305 rotates synchronously with the movement of the chainring. Finally, the ejected chainring slides along the blanking plate 402 through the blanking chute 401 to the collection area. No manual intervention is required throughout the process, which not only avoids the safety hazards of manual operation, but also improves the stability of molding and blanking through the precise coordination of the mechanical structure.

10. A control method for a super-hard alloy crankset forming machine tool based on claim 9, characterized in that: The steps include: Step 1: The super-hard alloy toothed disc is placed at the entrance of the slide groove (204) of the trapezoidal seat (203). The toothed disc slides downward along the slide groove (204) under the action of gravity. The guide plate (2053) in the guide assembly (205) is kept in an inclined state under the elastic force of the first spring (2055), thereby providing preliminary guidance for the toothed disc. At the same time, the extrusion plate (2054) is slightly displaced by the extrusion of the toothed disc, thereby triggering the transmission assembly (206) to start. Step 2: The toothed disc continues to slide down along the slide groove (204), and the extrusion plate (2054) is completely squeezed into the groove (2051) by the toothed disc, driving the guide plate (2053) to rotate around the first fixed axis (2052), driving the extrusion plate (2054) to squeeze the transmission bar (2062), and the extruded transmission bar (2062) rotates around the second fixed axis (2061), driving the sector gear (2063) to rotate, and the sector gear (2063) is meshed with the circular gear (301) to drive the circular gear (301) to rotate around the third fixed axis (302), and the rotational force is transmitted to the pressing plate (3041) through the shifting rod (303); Step 3: When the circular gear (301) rotates, the shifting rod (303) rotates synchronously and squeezes the push rod (3042) in the energy storage assembly (304); the push rod (3042) rotates around the limiting column (3043) and stretches the elastic rope (3044), so that the elastic rope (3044) stores elastic potential energy; the pressing plate (3041) moves to the side of the shifting rod (303) along with the push rod (3042); the second spring (2069) on the surface of the transmission bar (2062) is stretched, providing power for subsequent resetting; Step 4: When the toothed disc slides to the entrance of the casting cavity (105), the elastic potential energy stored in the energy storage component (304) is released through the push rod (3042), and the push rod (3042) pushes the toothed disc to completely enter the casting cavity (105). After the toothed disc is cast in the casting cavity (105), the push rod (106) rises, and the inclined surface of the push rod (106) contacts the toothed disc formed in the casting cavity (105), tilting the toothed disc out of the casting cavity (105) and falling at the outlet of the blanking plate (402). The ejected toothed disc slides along the blanking plate (402) through the blanking trough (401) to the collection area.
