[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 3 The diagram shown is a structural schematic of an automatic feeding and shaping machine provided by this utility model. The automatic feeding and shaping machine includes a feeding device 10 and a shaping device 20 disposed on one side of the feeding device 10. It is conceivable that the automatic feeding and shaping machine also includes other functional structures, such as guide rail supports, screw holes, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0019] The loading device 10 includes a loading worktable 11 fixed to the ground, a vibratory feeder 12 fixedly mounted on the loading worktable 11, and a loading guide rail 13 mounted on the loading worktable 11 and located between the vibratory feeder 12 and the shaping device 20. One end of the loading guide rail 13 is connected to the vibratory feeder 12, and the other end faces the shaping device 20. The vibratory feeder 12 can transport the workpiece along its own track to the loading guide rail 13 by vibration. The loading device 10 transports the workpiece to be shaped to the shaping device 20 through the vibratory feeder 12 and the loading guide rail 13.

[0020] The shaping equipment 20 includes a shaping worktable 21 fixed on the ground, a support 22 disposed on the shaping worktable 21, a drive device 23 disposed on one end of the support 22 away from the shaping worktable 21, an upper mold assembly 24 disposed on the side of the support 22 away from the shaping worktable 21, a lower mold assembly 25 disposed on the side of the support 22 close to the shaping worktable 21, and a wedge pusher mechanism 26 disposed between the upper mold assembly 24 and the lower mold assembly 25.

[0021] It is conceivable that a material drop hole is provided in the middle area of ​​the shaping worktable 21, so that the shaped bushing can fall from the material drop hole for easy collection.

[0022] Please see Figure 1 The outer contour of the support 22 is U-shaped. Two reinforcing ribs 221 are provided at the end of the support 22 away from the shaping worktable 21 to improve the load-bearing capacity and structural strength of the support 22.

[0023] The driving device 23 comprises a telescopic mechanism 231 arranged on the support 22, a transmission mechanism 232 arranged on the end of the telescopic mechanism 231 away from the support 22, and a driving motor 233 arranged on the transmission mechanism 232. The movable end of the telescopic mechanism 231 penetrates through the support 22 and is connected with the upper die assembly 24. A connecting piece 234 is arranged on the movable end of the telescopic mechanism 231. The other end of the connecting piece 234 is connected with the upper die assembly 24, so as to drive the upper die assembly 24 to move along the axial direction of the telescopic mechanism 231. The structure and working principle of the telescopic mechanism 231 are prior art, and thus will not be described here in detail.

[0024] The transmission mechanism 232 can be an existing belt transmission, chain transmission, gear transmission and the like, and its purpose is to transmit the power of the driving motor 233 to the telescopic mechanism 231, so that the telescopic mechanism 231 can reciprocate.

[0025] The upper die assembly 24 comprises an upper die frame 241 connected with the connecting piece 234 at one end, and a pressing head 242 arranged on the upper die frame 241 at the middle region of the end face facing the lower die assembly 25.

[0026] The upper die frame 241 reciprocates under the driving of the telescopic mechanism 231. At least two guide sleeves 243 are further arranged on the end face of the upper die frame 241 facing the lower die assembly 25. The guide sleeves 243 are tubular members and play a guiding role. The upper die frame 241 is provided with through holes corresponding to the inner holes of the two guide sleeves 243. The guide sleeves 243 are used in cooperation with the lower die assembly 25, which will be described below.

[0027] The pressing head 242 is used for pressing the shaft sleeve to be shaped into the lower die assembly 25. Its shape and size should be designed according to the shape and size of the shaft sleeve to be shaped.

[0028] The lower die assembly 25 comprises a lower die frame 251 arranged in the support 22, two guide rods 252 arranged on the lower die frame 251, a feeding track 253 arranged on the side of the lower die frame 251 facing the feeding device 10, a shaping hole 254 arranged in the middle region of the lower die frame 251, and a feeding groove 255 arranged on the lower die frame 251 and communicating with the feeding track 253 and the shaping hole 254 at both ends respectively.

[0029] The lower die frame 251 is inserted into the guide sleeve 243 through two guide rods 252, and the lower die frame 251 is fixedly connected with the support 22, so that the upper die frame 241 can be prevented from shaking during use. The two guide rods 252 can pass through the through holes on the upper die frame 241 through the guide sleeve 243, so as to ensure the consistency of the upper die assembly 24 and the lower die assembly 25 during movement.

[0030] Please refer to Figure 2 The lower die frame 251 is stepped towards one side of the feeding device 10, and one end of the feeding rail 253 is arranged on the step of the lower die frame 251. One end of the feeding rail 253 is in communication with the feeding rail 13, and the other end is fixedly arranged on the step of the lower die frame 251 and in communication with the feeding groove 255, so as to guide the shaft sleeve in the feeding rail 13 into the feeding groove 255. The inner bottom surface of the feeding rail 253 and the end surface of the feeding groove 255 are in the same horizontal plane. The feeding rail 253 and the lower die frame 251 can be connected and fixed by bonding, welding or the like.

[0031] The sizing hole 254 coincides with the center axis of the pressing head 242, and the size of the sizing hole 254 is greater than that of the pressing head 242, so that the pressing head 242 can be inserted into the sizing hole 254. It is conceivable that the sizing hole 254 corresponds to the position of the blanking hole on the sizing workbench 21. Different shape specifications of sizing dies can be embedded in the sizing hole 254 according to actual needs, so as to shape shaft sleeves of different specifications without changing the size of the sizing hole 254, thereby increasing the applicable range.

[0032] The inclined wedge feeding mechanism 26 comprises a guide rail 261 arranged on the side of the lower die frame 251 away from the feeding device 10, a sliding block 262 slidingly arranged on the guide rail 261, a return spring 263 arranged on one end of the sliding block 262, an inclined wedge 264 arranged on the side of the upper die frame 241 away from the feeding device 10, a push rod 266 arranged on the end face of the sliding block 262 towards the feeding groove 255, and a push head 267 arranged on the end of the push rod 266.

[0033] The sliding block 262 slides along the guide rail 261, and the return spring 263 enables the sliding block 262 to return to the initial position when not subjected to external force. The sliding block 262 is arranged corresponding to the inclined wedge 264. The end face of the sliding block 262 towards the inclined wedge 264 is inclined, and is parallel to the inclined face of the inclined wedge 264.

[0034] The outer contour shape of the inclined wedge 264 please refer to Figure 1The inclined wedge 264 is inclined towards one side of the slider 262, and the inclined surface of the inclined wedge 264 matches the inclined surface of the slider 262, so that when the inclined wedge 264 is driven by the upper mold assembly 24 to move downwards, the slider 262 is driven to slide on the guide rail 261, and in particular, in this embodiment, when the inclined wedge 264 is driven by the upper mold assembly 24 to move downwards, the slider 262 slides away from the side of the shaping hole 254 to push the next material to be shaped.

[0035] When the slider 262 is in the initial position, the inclined surface of the inclined wedge 264 matches the inclined surface of the slider 262. One end of the push rod 266 is fixedly arranged on the slider 262, and the other end extends to the feeding groove 255. The push head 267 is connected with the free end of the push rod 266 and is accommodated in the feeding groove 255.

[0036] The end of the push head 267 towards the shaping hole 254 is concave arc-shaped, which can better match the shape of the shaft sleeve and make the shaft sleeve bear force uniformly to avoid rolling of the shaft sleeve. When the slider 262 is in the initial position, the push head 267 and the push rod 266 partially overlap with one end of the feeding rail 253, so as to block the shaft sleeve in the feeding rail 253 from entering the feeding groove 255 and prevent the shaft sleeve from falling off.

[0037] When in use, the driving mechanism 23 pushes the upper die holder 241 to move towards the lower die holder 251, and then the inclined wedge 264 contacts with the inclined surface of the slider 262. As the upper die holder 241 is pressed down, the contact surface between the inclined wedge 264 and the slider 262 gradually increases, so that the slider 262 slides outwards along the guide rail 261 as a whole. At this time, the push rod 266 and the push head 267 slide with the slider 262 until the push rod 266 and the push head 267 no longer block one end of the feeding track 253, at which time, one shaft sleeve is pushed into the feeding groove 255 under the pushing of other shaft sleeves. Then, the driving mechanism 23 drives the upper die holder 241 to move away from the lower die holder 251, and when the slider 262 is not under the action of external force, it is reset by the reset spring 263, while driving the push head 267 to push the shaft sleeve into the shaping hole 254, and at the same time block one end of the feeding track 253. Then, the above steps are repeated again, and a new shaft sleeve will enter the feeding groove 255, and since a shaft sleeve has been placed in the shaping hole 254, the pressure head 242 will press the shaft sleeve into the mold in the shaping hole 254. And the push head 267 will push the next shaft sleeve into the shaping hole 254, and the above steps will be repeated subsequently. And after the shaping of the previous shaft sleeve, it will be embedded in the shaping hole 254, and the next shaft sleeve will push the previous shaft sleeve out of the shaping hole 254.

[0038] It should be noted that the stroke of the inclined wedge 264 and the slider 262, the stroke of the push head 267 and the stroke of the pressure head 242 should be strictly set. Specifically, when the inclined wedge 264 is pressed down to the maximum stroke, the inclined surface of the inclined wedge 264 still maintains contact with the inclined surface of the slider 262. The pressure head 242 is inserted into the shaping hole 254. The push head 267 will slide with the slider 262 along the feeding groove 255, and no longer block the feeding track 253, at which time the shaft sleeve will enter the feeding groove 255. As the inclined wedge 264 rises, it gradually comes out of contact with the slider 262, and the pressure head 242 also rises with the inclined wedge 264. The slider 262 is reset under the action of the pulling force of the reset spring 263. When the inclined wedge 264 comes out of contact with the slider 262, and the slider 262 returns to the initial position, the end surface of the push head 267 provided with a circular arc is located at the side of the shaping hole 254, and at the same time, the shaft sleeve is pushed into the shaping hole 254.

[0039] Compared with the prior art, the automatic feeding and shaping machine provided by the utility model realizes the automatic feeding and shaping of the shaft sleeve by setting the upper die holder 241 and the lower die holder 251 in the support 22, setting the pressing head 242 and the inclined wedge 264 on the upper die holder 241, setting the shaping hole 254 on the lower die holder 251 to cooperate with the pressing head 242 to shape the shaft sleeve, connecting the discharging track 13 with the feeding track 253 to avoid the grabbing step of the mechanical claw and make the shaft sleeve conveying more stable, setting the feeding groove 255 on the lower die holder 251 to place the single shaft sleeve, setting the inclined wedge pushing mechanism 26 on the lower die holder 251 to cooperate with the inclined wedge 264, driving the pushing head 267 to slide along the feeding groove 255 through the friction of the two inclined surfaces of the sliding block 262 and the inclined wedge 264, making the shaft sleeve in the feeding track 253 fall into the feeding groove 255 in the process of the outward sliding of the pushing head 267, pulling the sliding block 262 back to the original position through the reset spring 263, and pushing the shaft sleeve into the shaping hole 254 through the pushing head 267, so as to realize the automatic feeding and improve the shaping efficiency.
