[0001] This invention relates to the field of stamping machine tool technology, specifically to a rotary automated stamping machine tool parts processing device. Background Technology

[0002] As my country's economy continues to develop, stamping machines, as the most fundamental link in the manufacturing industry, are receiving increasing attention. A Chinese invention patent with publication number CN 114643325 A discloses a stamping machine for batch processing of mechanical parts. The moving mechanism includes a base plate, guide rail, moving component, sliding seat, and lifting component. The end of the base plate is fixed to the outer side of the base for mounting the guide rail, which facilitates the sliding of the sliding seat. The moving component includes a first threaded rod, a motor, and a first threaded seat. The rotation of the motor drives the first threaded rod to rotate. This invention has the advantages of reducing personnel, simplifying the structure, and reducing usage and production costs.

[0003] However, the inventors discovered the following problems with the device: after the parts are stamped, they will deform, and the clamping mechanism of the device may fail to clamp them properly; the unloading mechanism is prone to deforming the parts when unloading, and the noise generated when the parts fall is too loud. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies. By setting up a rotary mechanism and a pushing mechanism on the rotary mechanism, and by making the front end of the pushing rod magnetic, the problem of deformation of parts after stamping and the inability of the clamping mechanism to clamp properly is solved. By setting up a buffer mechanism below the unloading mechanism, and by making the front ends of both support blocks a and b of flexible material, the problem of easy deformation of parts during unloading at the unloading mechanism of the original device and excessive noise generated when parts fall is solved.

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution:

A rotary mechanism is provided at the front end of the machine tool, with several pushing mechanisms and actuating rods respectively. A guide rail is provided at the upper end of the rotary mechanism. The pushing mechanisms, driven by a servo motor, rotate with the rotary mechanism, pushing parts to move on the support frames a and b. A material frame is provided at the rear end of the support frame b, with a discharging mechanism at the upper end and a buffer mechanism in the middle. The discharging mechanism receives parts pushed by the pushing mechanisms and transfers the received parts to the buffer mechanism by opening and pressing simultaneously.

[0009] As a preferred embodiment, the feeding mechanism includes a material support assembly a, a pressing assembly, and a telescopic assembly. The material support assembly a includes a support plate a slidably disposed on a support frame b, a support plate b slidably disposed on a support frame b, a connector a connecting piece a to the hinged support plate a, a connector b connecting the hinged support plate b, and a lifting rod for the hinged connector a and the connector b.

[0010] As a preferred embodiment, the clamping assembly is located at the lower end of the lifting rod. The clamping assembly includes a body, a telescopic rod a slidably mounted on the body, and a rigid rubber pad connected to the lower end of the telescopic rod a. A spring a is provided between the body and the telescopic rod a.

[0011] As a preferred embodiment, the telescopic assembly includes a support leg mounted on a guide rail, a telescopic rod b slidably mounted on the support leg, and a connecting rod c connected to a lifting rod at one end. An L-shaped rod b is mounted on the connecting rod c, and a ramp is mounted on the L-shaped rod b. A spring b is mounted between the support leg and the telescopic rod b, and a spring c is connected between the connecting rod c and the connecting member b.

[0012] As a preferred embodiment, the guide rail is provided with a retractable section, a feeding section, and an extension section.

[0013] As a preferred embodiment, the buffer mechanism includes a buffer assembly a and a buffer assembly b. The buffer assembly a includes a fixed block b disposed on the machine tool, a telescopic rod c slidably disposed on the fixed block b, and a support block a slidably disposed on the telescopic rod c. The buffer assembly b includes a fixed block c disposed on the machine tool, a telescopic rod d slidably disposed on the fixed block c, and a support block b slidably disposed on the telescopic rod d. The front ends of both the support block a and the support block b are made of flexible material.

[0014] As a preferred embodiment, a spring d is provided between the telescopic rod c and the support block a, a spring e is provided between the telescopic rod d and the support block b, a spring f is provided between the fixed block b and the telescopic rod c, and a spring g is provided between the fixed block c and the telescopic rod d.

[0019] The beneficial effects of this invention are:

[0020] 1. In this invention, a servo motor is set to drive the rotary mechanism to rotate, and the push mechanism moves the parts by rotating with the rotary mechanism. The feeding mechanism and the buffer mechanism also work under the rotation of the rotary mechanism, which saves energy.

[0021] 2. In this invention, by providing magnetism at the front end of the push rod, the parts are more tightly attached to the push rod, and the parts are less likely to fall off.

[0022] 3. In this invention, by setting an L-shaped rod a and a protrusion a on the fixed block a, and setting an L-shaped rod b and a ramp on the connecting rod c, the fixed block a contacts the ramp through the protrusion a during rotation, causing the connecting rod c to move down, opening the pallet a and pallet b, and allowing the parts to fall into the material frame, which helps to save energy.

[0023] 4. In this invention, by setting a buffer mechanism in the middle of the material frame, and by making the front ends of both support block a and support block b of flexible material, the parts are less likely to deform during the falling process, and the noise generated when the parts fall is reduced.

[0024] In summary, this equipment has advantages such as energy saving and reduced noise generated when parts fall, and is especially suitable for the field of stamping machine technology. Attached Figure Description

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Example 1

[0041] like Figures 1 to 12 As shown, a rotary automated stamping machine tool parts processing device includes a machine tool 1, a bottom die 11, a support frame a2, and a support frame b3. The support frame a2 and support frame b3 are mounted on the machine tool 1 and located on both sides of the bottom die 11. A loading frame 4 is provided at the upper end of the support frame a2, and the loading frame 4 is connected to the machine tool 1 via a connecting rod a41. A rotary mechanism 5 is provided at the front end of the machine tool 1, and the rotary mechanism 5 is equipped with several pushing mechanisms 6 and actuating rods 7. The upper end of the rotating mechanism 5 is provided with a guide rail 20. The pushing mechanism 6 rotates with the rotating mechanism 5 under the drive of the servo motor 51, pushing the part 30 to move on the support frame a2 and the support frame b3. The rear end of the support frame b3 is provided with a material frame 10. The upper end of the material frame 10 is provided with a feeding mechanism 8, and the middle part of the material frame 10 is provided with a buffer mechanism 9. The feeding mechanism 8 is used to receive the part 30 pushed by the pushing mechanism 6 and transfer the received part 30 to the buffer mechanism 9 by opening and pressing at the same time.

[0042] It is worth mentioning that by setting a servo motor 51 to drive the rotary mechanism 5 to rotate, the push mechanism 6 rotates with the rotary mechanism 5 to move the part 30. The unloading mechanism 8 and the buffer mechanism 9 also work under the rotation of the rotary mechanism 5, which saves energy. By setting the buffer mechanism 9 in the middle of the material frame 10, and the front ends of the support block a913 and support block b923 are made of flexible material, the part 30 is less likely to deform during the falling process, and the noise generated when the part 30 falls is reduced.

[0043] like Figure 3 As shown, the pushing mechanism 6 includes a fixed block a61 and a pushing rod 62 slidably disposed on the fixed block a61. The front end of the pushing rod 62 is magnetic, and the fixed block a61 is disposed on the rotary mechanism 5.

[0044] It is worth mentioning that by providing magnetism at the front end of the push rod 62, the part 30 and the push rod 62 fit together more tightly, making it less likely for the part to fall off.

[0045] like Figure 3 As shown, an L-shaped rod a611 is provided on the fixing block a61, and a protrusion a612 is provided at the front end of the L-shaped rod a611.

[0046] It is worth mentioning that by setting an L-shaped rod a611 and a protrusion a612 on the fixed block a61, and setting an L-shaped rod b8331 and a ramp 8332 on the connecting rod c833, the fixed block a611 contacts the ramp 8332 through the protrusion a612 during rotation, which drives the connecting rod c833 to move down, opening the pallet a913 and pallet b923, allowing the part 30 to fall into the material frame 10, which helps to save energy.

[0047] like Figure 6 As shown, the feeding mechanism 8 includes a material support assembly a81, a pressing assembly 82, and a telescopic assembly 83. The material support assembly a81 includes a support plate a811 slidably mounted on the support frame b3, a support plate b812 slidably mounted on the support frame b3, a connector a813 for hinged support plate a811, a connector b814 for hinged support plate b812, and a lifting rod 815 for hinged connector a813 and connector b814. The material support assembly a81 is sleeved on the connecting rod b31, and the connecting rod b31 is mounted on the support frame b3.

[0048] The clamping assembly 82 is disposed at the lower end of the lifting rod 815. The clamping assembly 82 includes a body 821, a telescopic rod a822 slidably disposed on the body 821, and a hard rubber pad 823 connected to the lower end of the telescopic rod a822. A spring a824 is disposed between the body 821 and the telescopic rod a822.

[0049] like Figure 7 As shown, the telescopic assembly 83 includes a support leg 831 mounted on the guide rail 20, a telescopic rod b832 slidably mounted on the support leg 831, and a connecting rod c833 connected at one end to the lifting rod 815. An L-shaped rod b8331 is mounted on the connecting rod c833, and a ramp 8332 is mounted on the L-shaped rod b8331. A spring b834 is mounted between the support leg 831 and the telescopic rod b832, and a spring c8333 is connected between the connecting rod c833 and the connecting member b814.

[0050] In this example, by setting springs a824, b834 and c8333, the unloading mechanism 8 can be reset after placing part 30.

[0051] like Figure 11 As shown, the guide rail 20 is provided with a retractable section 201, a feeding section 202, and an extension section 203.

[0052] In this example, the retraction section 201 allows the push rod 62 to disengage from the part 30 before contacting the unloading mechanism 8, so that the push rod 62 will not collide with the unloading mechanism 8. The unloading section 202 prevents the push rod 62 from colliding with the unloading mechanism 8 that is unloading.

[0053] like Figure 9 As shown, the buffer mechanism 9 includes a buffer assembly a91 and a buffer assembly b92. The buffer assembly a91 includes a fixed block b911 mounted on the machine tool 1, a telescopic rod c912 slidably mounted on the fixed block b911, and a support block a913 slidably mounted on the telescopic rod c912. The buffer assembly b92 includes a fixed block c921 mounted on the machine tool 1, a telescopic rod d922 slidably mounted on the fixed block c921, and a support block b923 slidably mounted on the telescopic rod d922. The front ends of both the support block a913 and the support block b923 are made of flexible material.

[0054] It is worth noting that the front ends of both support blocks a913 and b923 are made of flexible material to provide better cushioning for part 30, and the telescopic rod d922 is shaped in this way to facilitate the disassembly of the material frame 10.

[0055] like Figure 9 , 10 As shown, a spring d914 is provided between the telescopic rod c912 and the support block a913, a spring e924 is provided between the telescopic rod d922 and the support block b923, a spring f915 is provided between the fixing block b911 and the telescopic rod c912, and a spring g925 is provided between the fixing block c921 and the telescopic rod d922.

[0056] It is worth noting that the buffer mechanism 9 is reset by springs f915 and g925. When the part 30 in the material frame 10 is level with the buffer mechanism 9, the support block a913 and support block b923 are respectively compressed by springs d914 and e924, so that the support block a913 and support block b923 will not enter the material frame 10.

[0057] like Figure 11 As shown, the material frame 10 is provided with a retaining strip 101, and the machine tool 1 is provided with a retaining groove 12. The material frame 10 is mounted on the machine tool 1 through the cooperation of the retaining strip 101 and the retaining groove 12.

[0058] In this example, by setting the card strip 101 and the card slot 12, the assembly and disassembly of the material frame 10 are made more convenient.

[0059] The pushing mechanism 6 is located at the upper end of the rotating mechanism 5, and the actuating rod 7 is located at the lower end of the rotating mechanism 5. The pushing mechanism 6 and the actuating rod 7 are staggered.

[0060] It is worth noting that the push mechanism 6 and the actuation lever 7 are staggered so that the feeding mechanism 8 and the buffer mechanism 9 can release part 30 in a staggered manner.

[0061] like Figure 12As shown, a partition 42 is provided at the lower end of the feeding frame 4, and the parts fall down along the partition 42. Only the push rod can pass between the feeding frame 4 and the support frame a2.

[0062] The thickness of the push rod 62 is less than the thickness of the plate of part 30.

[0063] It is worth noting that when the thickness of the push rod 62 is less than the thickness of the part 30 plate, the machine tool 1 will not touch the push rod 62 during the stamping of the part 30.

[0064] The work process is as follows:

[0065] Servo motor 51 drives rotary mechanism 5 to rotate. Push mechanism 6 and lever 7 also rotate under the drive of rotary mechanism 5. The part 30 is placed in the loading frame 4 by the operator. The part 30 falls onto the support frame a2 along the inner wall of loading frame 4 and partition 42. Push lever 62 moves part 30 forward along guide rail 20. When part 30 moves onto bottom mold 11, servo motor 51 stops running. Machine tool 1 stamps part 30. After stamping, servo motor 51 continues to run, and push lever 62 pushes part 30 forward.

[0066] When part 30 contacts pallet a811 and pallet b812, push rod 62 moves to retract section 201 on guide rail 20. As it continues to move forward, push rod 62 moves backward along retract section 201. When it reaches unloading section 202, push rod 62 pushes part 30 completely into unloading mechanism 8. After push rod 62 enters unloading section 202, protrusion a612 on L-shaped rod a611 contacts inclined platform 8332 on L-shaped rod b8331, causing connecting rod c833 to move down, driving lifting rod 815 to move down. Lifting rod 815 pushes connecting piece a813 and connecting piece b814 to move diagonally downward, driving pallet a811 and pallet b812 to move outward. Part 30 falls onto buffer mechanism 9. Unloading mechanism 8 is reset by spring a824, spring b834 and spring c8333.

[0067] The rotary mechanism 5 continues to rotate, the actuating rod 7 continues to move forward, the actuating rod 7 touches the telescopic rod c912 and the telescopic rod d922, the telescopic rod c912 drives the support block a913 to move backward and out of the material frame 10, the telescopic rod d922 drives the support block b923 to move forward and out of the material frame 10, the part 30 falls to the bottom of the material frame 10, and the buffer mechanism 9 is reset by the spring f915 and the spring g925;

[0068] When the parts 30 are stacked to a distance of only one part 30 from the buffer mechanism 9, the buffer mechanism 9 puts in the next part 30 and then enters again. At this time, there are parts at the front ends of both the support block a913 and the support block b923. The support block a913 and the support block b923 are prevented from entering the material frame 10 by compression springs d914 and e924 respectively.

[0069] When parts 30 fill the material frame 10, the material frame 10 is manually disassembled and replaced with a new material frame 10.
