Description

Technical Field

[0001] The present invention relates to the technical field of forming presses, and in particular to a material conveying mechanism of a hot pressing forming press. Background Art

[0002] Existing fully automatic hot pressing presses, such as the Chinese patent (application publication number CN108248088A), mainly include a sealed frame, in which a feeding device, a feeding device, a heating device and a forming device are arranged. The blank first enters the feeding device through the feeding device, and the feeding device then places the blank into the forming mold, and then generates magnetism through heating, and then the blank is processed and formed by the forming device.

[0003] In the existing hot pressing press, the blank is preheated by a heating device so that the temperature of the blank is close to the temperature required for the pressing process (900℃±5℃). However, heating the blank at room temperature to a temperature close to the temperature required for the pressing process (900℃±5℃) by a heating device at one time has the following disadvantages: on the one hand, one-time heating will lead to low heating efficiency and high energy consumption required for heating; on the other hand, it is easy to affect the performance of the blank. Therefore, it is generally necessary to set a preheating device at the forefront of the feeding device, preheat the blank by the preheating device, and then heat the blank again by the heating device to make the temperature of the blank close to the temperature required for the pressing process (900℃±5℃). Finally, the blank is heated for a third time by the medium frequency coil in the forming device to reach the temperature required for the pressing process.

[0004] However, on the one hand, how to automatically transport the stacking rack located in the preheating device to the location of the feeding device is a technical problem that needs to be solved urgently. On the other hand, how to automatically recycle the empty stacking rack and effectively prevent outside air from entering the sealed molding press is also a technical problem that needs to be solved urgently. Summary of the Invention

The output end of the material ejecting mechanism pushes the blank upward through the through holes.

[0010] Furthermore, the first end of the hooking mechanism is pivotally connected to the base plate, and the output end of the pushing mechanism is pivotally connected to the second end of the hooking mechanism through a connecting piece. The pushing mechanism can drive the hooking mechanism to rotate so that the connecting block and the towing hook can be limited or released.

[0011] Furthermore, a support base is provided on the bottom plate, and the hooking mechanism is arbitrarily arranged on the support base. The pushing mechanism is connected to the bottom plate via the support base, and the pushing mechanism can drive the hooking mechanism to move up and down to achieve the limited engagement and release of the limited engagement between the connecting block and the towing hook.

[0012] Furthermore, the rotating disk is provided with a second track at the other end relative to the hooking mechanism. The second track is arranged flush with the first track. There is a gap between the second track and the first track for the first track to rotate freely. The stacking rack transitions to the first track through the second track.

[0013] Furthermore, the second rail is fixed to the base plate through a connecting device, and the guide groove of the second rail is flush with the guide groove of the first rail.

[0014] Furthermore, the stacking rack includes a stacking tray and a plurality of storage barrels circumferentially arranged at the upper end of the stacking tray, the storage barrel has a cavity that passes through from top to bottom, the cavity is used to stack the blanks, the through hole is arranged at the position of the output end of the stacking tray corresponding to the top material mechanism, and the aperture of the through hole is smaller than the inner diameter of the cavity.

[0015] Furthermore, a pushing mechanism and a recovery mechanism are also provided on the base plate. The pushing mechanism, the second track, the recovery mechanism and the material hooking mechanism are distributed around the rotating disk in sequence. The recovery mechanism includes a lifting platform that can be lifted up and down relative to the base plate.

[0016] Furthermore, the recovery mechanism includes a sealing frame arranged at the lower end of the base plate and a lifting cylinder connected to the lower end of the sealing frame, the output end of the lifting cylinder is connected to the lifting platform, the base plate is provided with a channel for the lifting platform to pass through, the upper end of the lifting platform is connected to a sealing cover capable of sealing the channel, and a accommodating space for accommodating a stacking rack is provided between the sealing cover and the lifting platform.

[0017] Furthermore, an openable sealing door is provided on one side of the sealing frame.

[0018] Furthermore, the lifting platform is provided with a limiting block that cooperates with the stacking rack to limit the position.

[0019] In summary, the present invention has the following beneficial effects:

[0020] A material transport mechanism of a hot pressing press can automatically transfer the stacking rack in the preheating device to the bottom plate of the feeding mechanism, and has the function of automatically recovering the stacking rack. The specific operation process is as follows:

[0021] 1. The pushing mechanism lifts up the second end of the hooking mechanism (the end adjacent to the output end). The hooking mechanism pushes the connecting block to the front end of the towing hook. The pushing mechanism resets and drives the second end of the hooking mechanism downward to limit the connection between the connecting block and the towing hook. The output end of the hooking mechanism resets and drives the stacking rack to move along the second track to the first track. The pushing mechanism lifts up the second end of the hooking mechanism to enable the stacking rack to rotate freely.

[0022] 2. The stacking rack rotates the rotating disk at the lower end of the first track so that the output end of the ejecting mechanism corresponds to the position of the storage barrel. The output end of the ejecting mechanism intermittently lifts the blanks in the storage barrel, and the ejected blanks are removed one by one by the feeding mechanism. When the blanks in the storage barrel are taken out, the output end of the ejecting mechanism resets, and the rotating disk drives the stacking rack to continue rotating a certain angle so that the position of another storage barrel corresponds to the output end of the ejecting mechanism, and then the above action is repeated;

[0023] 3. When all the blanks on the stacking rack are taken out, the rotating disk drives the first track and the stacking rack to rotate so that the length direction of the first track faces the lifting platform. The pushing mechanism pushes the stacking rack to move along the first track to the lifting platform and then reset. (If all the blanks on the stacking rack are taken out and the length direction of the first track is just facing the lifting platform, the rotating disk can move without rotating the pushing mechanism). The lifting cylinder drives the lifting platform down to the position of the sealing cover sealing channel. At this time, the accommodating space is isolated from the sealed frame, and the staff takes the stacking rack out of the sealed frame through the sealed door. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-4 As shown, a material transport mechanism of a hot pressing press comprises a bottom plate 1, a material hooking mechanism 3, a material lifting mechanism 4 and a material stacking rack 5. The bottom plate 1 is arranged on a feeding station, and a rotating disk 2 is provided on the bottom plate 1. The rotating disk 2 is an electric rotating device. A first track 21 is provided on the rotating disk 2. The material stacking rack 5 can slide along the first track 21. The rotating disk 2 can drive the first track 21 and the material stacking rack 5 to rotate. The other end of the rotating disk 2 relative to the material hooking mechanism 3 is provided with a second track 11, and the second track 11 is arranged flush with the first track 21. There is a gap between the second track 11 and the first track 21 for the first track 21 to rotate freely, and the stacking rack 5 transitions to the first track 21 through the second track 11. Specifically, the second track 11 is arranged on the side of the rotary disk 2 corresponding to the preheating device, and the bottom of the stacking rack 5 is provided with a guide portion 51 that slides with the second track 11 and the first track 21. The gap between the second track 11 and the first track 21 can ensure that the second track 11 and the first track 21 will not interfere with each other during the process of the rotary disk 2 driving the first track 21 to rotate.

[0031] The second rail 11 is fixed to the base plate 1 by a connecting device 13. The guide groove of the second rail 11 is flush with the guide groove of the first rail 21. At the same time, the distance between the adjacent ends of the second rail 11 and the first rail 21 is less than the length of the guide part 51 at the bottom of the stacking rack 5. Through this design, the stacking rack 5 can smoothly and smoothly transition from the second rail 11 to the first rail 21, and the stacking rack 5 will not shift during the movement.

[0032] The hooking mechanism 3 is arranged on the base plate 1 and is located at the other end of the rotating disk 2 relative to the second track 11, that is, the hooking mechanism 3 is arranged on the other side of the preheating device. The hooking mechanism 3 in the present invention is a hooking cylinder. Of course, as an equivalent alternative, the hooking mechanism 3 can also be an electric push rod, a hydraulic cylinder, etc. A tow hook 52 is provided on the stacking rack 5, and a connecting block 31 is provided at the output end of the hooking mechanism 3. When the hooking mechanism 3 is actuated, it can drive the connecting block 31 to extend to the stacking rack 5 located in the preheating device. The hooking mechanism 3 is limited by the connecting block 31 and the tow hook 52 to drive the stacking rack 5 from the track in the preheating device through the second track 11 to the first track 21. A pushing mechanism 6 is provided on the base plate 1 to lift the hooking mechanism 3 to release the limiting cooperation between the connecting block 31 and the tow hook 52.

[0033] The first arrangement of the hooking mechanism 3: the first end of the hooking mechanism 3 (far away from the output end of the hooking mechanism 3) is pivotally connected to the base plate 1, and the output end of the pushing mechanism 6 is pivotally connected to the second end of the hooking mechanism 3 (close to the output end of the hooking mechanism 3) through a connecting piece. The pushing mechanism 6 can drive the hooking mechanism 3 to rotate so that the connecting block 31 and the towing hook 52 are limited or released.

[0034] The second setting method of the hooking mechanism 3: a support seat is provided on the base plate 1, and the hooking mechanism 3 can be raised and lowered on the support seat. The pushing mechanism 6 is connected to the base plate 1 through the support seat, and the pushing mechanism 6 can drive the hooking mechanism 3 to rise and fall to achieve the limiting cooperation and release of the limiting cooperation between the connecting block 31 and the towing hook 52.

[0035] like Figure 1 and Figure 3 As shown, a lifting mechanism 4 is provided at the lower end of the base plate 1, and a plurality of through holes 53 corresponding to the storage barrels 55 on the stacking rack 5 are provided at the bottom of the stacking rack 5. The output end of the lifting mechanism 4 pushes the blank upward through the through hole 53. In the present invention, the lifting mechanism can use a power device such as an electric cylinder or an electric push rod.

[0036] The stacking rack 5 includes a stacking tray 54 and a plurality of storage barrels 55 circumferentially arranged on the upper end of the stacking tray 54. The storage barrel 55 has a cavity that passes through from top to bottom. The cavity is used to stack blanks and the cavity wall matches the outer wall of the blank. The aperture of the through hole 53 is smaller than the inner diameter of the cavity. The purpose of this design is to support the blanks stacked in the cavity through the stacking tray 54 before they are lifted up by the output end of the lifting mechanism 4.

[0037] The base plate 1 is also provided with a pushing mechanism 7 and a recovery mechanism 8. The pushing mechanism 7, the second track 11, the recovery mechanism 8 and the hooking mechanism 3 are distributed around the rotating disk 2 in sequence. This arrangement makes the overall structure of the material transport device more compact and the layout more reasonable.

[0038] The recycling mechanism 8 includes a lifting platform 81 that can be lifted up and down relative to the base plate 1. The pushing mechanism 7 can push the stacking rack 5 to move along the first track 21 to the lifting platform 81. Specifically, when all the blanks on the stacking rack 5 are taken out, the stacking rack 5 is pushed to the lifting platform 81 by the pushing mechanism 7 to recycle the empty stacking rack 5. In order to prevent the stacking rack 5 from sliding out of the lifting platform 81 under the push of the pushing mechanism 7, a limit block 811 that cooperates with the stacking rack 5 is provided on the lifting platform 81.

[0039] The recycling mechanism 8 also includes a sealing frame 82 provided at the lower end of the bottom plate 1 and a lifting cylinder 83 connected to the lower end of the sealing frame 82. The output end of the lifting cylinder 83 is connected to the lifting platform 81. The bottom plate 1 is provided with a channel 12 for the lifting platform 81 to pass through. The upper end of the lifting platform 81 is connected to a sealing cover 84 capable of sealing the channel 12. Specifically, columns are provided around the lifting platform 81. The sealing cover 84 is installed on the upper end of the lifting platform 81 through the columns. A accommodating space 85 for accommodating the stacking rack 5 is provided between the sealing cover 84 and the lifting platform 81, and the accommodating space 85 faces the rotating disk 2. The distance between the two columns at one end is sufficient for the stacking rack 5 to pass through, that is, the accommodating space 85 is provided with a passage for the stacking rack 5 to enter the accommodating space 85 at one end toward the rotating disk 2, and an openable sealing door 821 is provided on one side of the sealing frame 82. The purpose of providing the sealing cover 84 is that after the lifting platform 81 receives the stacking rack 5, it retreats into the sealing frame 82 under the action of the lifting cylinder 83, and at this time the sealing cover 84 seals the passage 12, and then when the staff opens the sealing door 821 to take the material, the sealing frame 82 and the sealed molding press are isolated, thereby effectively preventing outside air from running into the sealed molding press.

[0040] The specific principles of the present invention are:

[0041] 1. The pushing mechanism 6 lifts the second end (the end adjacent to the output end) of the hooking mechanism 3. The hooking mechanism 3 actuates to push the connecting block 31 to the front end of the towing hook 52. The pushing mechanism 6 resets and drives the second end of the hooking mechanism 3 downward so that the connecting block 31 and the towing hook 52 engage with each other. The output end of the hooking mechanism 3 resets and drives the stacking rack 5 to move along the second track 11 to the first track 21. The pushing mechanism 6 lifts the second end of the hooking mechanism 3 so that the stacking rack 5 can rotate freely.

[0042] 2. The stacking rack 5 rotates the rotating disk 2 at the lower end of the first track 21 so that the output end of the ejecting mechanism 4 corresponds to the position of the storage barrel 55. The output end of the ejecting mechanism 4 intermittently lifts the blanks in the storage barrel 55, and the ejected blanks are removed one by one by the feeding mechanism. When the blanks in the storage barrel 55 are taken out, the output end of the ejecting mechanism 4 is reset, and the rotating disk 2 drives the stacking rack 5 to continue to rotate a certain angle so that another storage barrel 55 corresponds to the position of the output end of the ejecting mechanism 4, and then repeats the above action;

[0043] 3. When all the blanks on the stacker 5 are taken out, the rotary disk 2 drives the first track 21 and the stacker 5 to rotate so that the length direction of the first track 21 faces the lifting platform 81. The pushing mechanism 7 pushes the stacker 5 to move along the first track 21 to the lifting platform 81 and then resets. (If all the blanks on the stacker 5 are taken out, the length direction of the first track 21 is just facing the lifting platform 81, the rotary disk 2 can move without rotating the pushing mechanism 7). The lifting cylinder 83 drives the lifting platform 81 to move down to the position where the sealing cover 84 seals the channel 12. At this time, the accommodating space 85 is isolated from the sealed frame, and the staff takes the stacker 5 out of the sealed frame 82 through the sealed door 821.

[0044] The stacking rack 5 of the present invention is provided with four groups of storage barrels 55 on the circumference. The hooking mechanism 3 hooks the stacking rack 5 to the first track 21 on the rotating disk 2. The rotating disk 2 is rotated by a certain angle so that the output end of the ejecting mechanism 4 corresponds to the position of the storage barrel 55, and the blank in the above storage barrel 55 is intermittently ejected by the ejecting mechanism 4. When the blank in the storage barrel 55 is taken out by the taking mechanism on the forming press, the rotating disk 2 is rotated by 90 degrees so that the blank in the other storage barrel 55 is aligned with the output end of the ejecting mechanism 4. Corresponding to the end, the lifting mechanism 4 intermittently lifts the blank in the storage barrel 55, and then the picking mechanism on the forming press takes the blank. When the blank in the storage barrel 55 is taken out, the rotary disk 2 rotates again and repeats the above action until the blank on the stacking rack 5 is taken out. When the blank on the stacking rack is completely taken out, the length direction of the first track 21 is just facing the lifting platform 81, and the stacking rack 5 is pushed along the first track 21 to move to the lifting platform 81 through the pushing mechanism 7.

[0045] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
