Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A progressive die with an automatic feeding mechanism, such as Figure 1 , including a fixed plate 1, two opposite baffles 2 and a progressive die body 3 arranged at the top of the fixed plate 1, a front plate 4 for placing raw materials is provided on the fixed plate 1, the front plate 4 is located on the left side of the progressive die body 3, and the end of the front plate 4 away from the progressive die body 3 is provided with a support leg in contact with the ground, the two baffles 2 are respectively located on the front and rear sides of the progressive die body 3, and the sides of the two baffles 2 close to each other are horizontally provided with a plurality of first resistance columns 5 located on the left side of the progressive die body 3, each first resistance column 5 is located above the front plate 4 and is spaced apart along the length direction of the baffle 2, each first resistance column 5 is in contact with the side wall of the raw material on the front plate 4, and a power member for simultaneously driving the two baffles 2 to move along a square track is provided on the fixed plate 1.

[0022] like Figure 1When in use, the raw material is placed between the two baffles 2 on the front plate 4, and then the two baffles 2 are driven by the power piece to move along the square trajectory at the same time. At this time, the two baffles 2 first approach each other until the first friction pillars 5 on the two baffles 2 conflict with the side walls of the raw material. At this time, the raw material can be clamped and positioned, and then the two baffles 2 drive each first friction pillar 5 to move in the direction close to the progressive mold body 3. At this time, the raw material will follow the first friction pillar 5 to approach the progressive mold body 3. After moving a certain distance, the two baffles 2 move away from each other until the first friction pillar 5 is separated from the raw material, and then the two baffles 2 drive the first friction pillar 5 to move back to the original position in the direction away from the progressive mold body 3. At this time, the movement of the baffle 2 along the square trajectory can be completed, and then the above process is repeated to automatically feed the raw material into the progressive mold body 3, and then it is processed by the progressive mold body 3. There is no need for manual feeding, which saves time and effort. The raw material is intermittently moved, and it is simple and convenient to use.

[0023] The progressive die body 3 can be a progressive die in a progressive die automatic feeding device with application number CN201620770633.5, which will not be described in detail in this application.

[0024] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The power part includes a connecting groove 6 opened on one side of the fixed plate 1, and two rectangular frames 7 are horizontally slidably connected between the groove walls on opposite sides of the connecting groove 6. The two rectangular frames 7 are distributed up and down and staggered. Square frames 8 are horizontally slidably connected in the two rectangular frames 7 along the length direction of the rectangular frames 7. The tops of the two square frames 8 are horizontally provided with hanging plates 9, and the ends of the two hanging plates 9 away from the square frames 8 are provided with U-shaped vertical plates 10. The ends of the two vertical plates 10 away from the hanging plates 9 are located above the fixed plate 1 and are fixedly connected to the two baffles 2 respectively. The fixed plate 1 is provided with a driving member for simultaneously driving the two square frames 8 to move horizontally in the rectangular frames 7 and driving the two rectangular frames 7 to move horizontally in the connecting groove 6. The moving directions of the two rectangular frames 7 are to approach or move away from each other, and the moving directions of the two square frames 8 in the rectangular frames 7 are consistent.

[0025] like Figure 1 and Figure 2 and Figure 3 and Figure 4When it is necessary to drive the two baffles 2 to move along the square trajectory to realize feeding, it is only necessary to drive the two square frames 8 to move horizontally left and right along the length of the rectangular frame 7 in the rectangular frame 7 through the driving member, and drive the two rectangular frames 7 to move horizontally forward and backward in the connecting groove 6. When the rectangular frame 7 moves horizontally forward and backward in the connecting groove 6, the baffle 2 will follow the rectangular frame 7 to move horizontally forward and backward through the vertical plate 10 and the hanging plate 9. At this time, the first contact column 5 on the baffle 2 can be made to contact or separate from the side wall of the raw material through the baffle 2 moving forward and backward. When the square frame 8 moves left and right in the rectangular frame 7, the baffle 2 will follow the square frame 8 to move left and right through the vertical plate 10 and the hanging plate 9. When the first contact column 5 contacts the side wall of the raw material and the two baffles 2 move to the right, the raw material can be driven to approach the progressive die body 3 for feeding through the first contact column 5 on the baffle 2; When the rectangular frame 7 moves, the square frame 8 inside the rectangular frame 7 stops moving inside the rectangular frame 7; when the square frame 8 moves, the rectangular frame 7 stops moving, which is simple and convenient to use.

[0026] like Figure 2 and Figure 3 and Figure 4 and Figure 5 The driving member includes a rotating groove 13 opened above the groove wall at the bottom end of the connecting groove 6, and a rotating drum 14 is rotatably connected in the rotating groove 13, and a rotating shaft 15 is rotatably connected in the rotating drum 14. A column 16 located above the rotating drum 14 is coaxially provided at the top of the rotating shaft 15. A first cam 17 located in the lower square frame 8 is provided on the rotating drum 14, and a second cam 18 located in the upper square frame 8 is provided on the column 16. The first cam 17 and the second cam 18 are both in contact with the inner wall of the square frame 8. The farthest end of the first cam 17 away from the rotating drum 14 and the farthest end of the second cam 18 away from the column 16 are respectively located at the opposite sides of the axis of the rotating drum 14. On both sides, the fixed plate 1 is provided with a rotating member for driving the rotating drum 14 and the rotating shaft 15 to rotate in opposite directions. The rotating member includes a conical gear ring 19 coaxially arranged at the bottom end of the rotating drum 14, and the bottom end of the rotating shaft 15 passes through the conical gear ring 19 and is provided with a first conical gear 20 located below the conical gear ring 19. A motor 21 is provided at the bottom end of the fixed plate 1, and one end of the rotating shaft of the motor 21 is provided with a second conical gear 22 located between the conical gear ring 19 and the first conical gear 20. The conical gear ring 19 and the first conical gear 20 are both meshed with the second conical gear 22, and the structure of the first cam 17 is consistent with that of the second cam 18.

[0027] like Figure 2 and Figure 3 and Figure 4 and Figure 5When it is necessary to drive the two square frames 8 to move in the rectangular frame 7 along the length direction of the rectangular frame 7 and to drive the two rectangular frames 7 to move horizontally in the connecting groove 6, it is only necessary to turn on the motor 21, and the rotating shaft of the motor 21 drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the rotating drum 14 and the rotating shaft 15 to rotate in opposite directions respectively through the first bevel gear 20 and the bevel gear ring 19 meshing therewith. At this time, the rotating shaft 15 will drive the column 16 to rotate. At this time, the column 16 and the rotating drum 14 will respectively drive the second cam 18 and the first cam 17 to rotate in opposite directions. At this time, the first cam 17 and the second cam 18 and the two square frames 8 By cooperating, the two square frames 8 can be driven to move synchronously in the rectangular frame 7 along the length direction of the rectangular frame 7. When the square frame 8 moves to the leftmost end or the rightmost end in the rectangular frame 7, the first cam 17 and the second cam 18 cooperate with the two square frames 8 and the two rectangular frames 7 to drive the rectangular frame 7 to move back and forth in the connecting groove 6. Because the farthest end of the first cam 17 away from the rotating drum 14 and the farthest end of the second cam 18 away from the column 16 are respectively located on the opposite sides of the axis of the rotating drum 14, and the second cam 18 rotates in opposite directions to the first cam 17, the two rectangular frames 7 move towards or away from each other, which is simple and convenient to use.

[0028] like Figure 1 A discharge plate 23 located on the right side of the progressive die body 3 is provided on the fixed plate 1, and a plurality of second resistance columns 24 located on the right side of the progressive die body 3 are provided on the side where the two baffles 2 are close to each other. Each second resistance column 24 is located above the discharge plate 23 and is spaced apart along the length direction of the discharge plate 23. The discharge plate 23 is located below the two baffles 2, and the discharge plate 23 is flush with the top of the front plate 4. The purpose of this arrangement is that the working process of the second resistance column 24 is consistent with that of the first resistance column 5. The discharge plate 23 is used to receive the raw material processed by the progressive die body 3. When the two baffles 2 move along the square trajectory so that the first resistance column 5 is in resistance against the side wall of the raw material for feeding, each second resistance column 24 will be in resistance against the side wall of the processed raw material. At this time, the second resistance column 24 can further facilitate feeding, and the use is simple and convenient.

[0029] like Figure 1 When the two baffles 2 are away from each other, a first fixing part for fixing the raw material is provided on the front plate 4, and a second fixing part for fixing the raw material is provided on the discharge plate 23. The purpose of this arrangement is that when the two rectangular frames 7 move to make the two baffles 2 move away from each other, and then the first resistance column 5 and the second resistance column 24 are separated from the raw material, the raw material is fixed by the first fixing part and the second fixing part. At this time, the horizontal displacement of the raw material when the raw material is processed in the progressive die body 3 can be reduced, the yield rate is improved, and it is simple and convenient to use.

[0030] like Figure 1 and Figure 3 and Figure 4 The first fixing member includes a long strip groove 25 opened at the top of the front plate 4 along the width direction of the front plate 4, and the long strip groove 25 is located between the two baffles 2, and two opposite sliders 26 are horizontally slidably connected in the long strip groove 25, and the tops of the two sliders 26 are provided with pressure plates 27, and the two pressure plates 27 are respectively located on both sides of the raw material on the front plate 4. The two rectangular frames 7 are connected to the two sliders 26 through a transmission member, and the structure of the second fixing plate 1 is consistent with that of the first fixing member. At this time, the long strip groove 25 is opened on the discharge plate 23 along the width direction of the discharge plate 23, and the transmission member includes vertical rods 28 both arranged at the tops of the two rectangular frames 7 and L-shaped transmission rods 29 both arranged at the bottom ends of the two sliders 26. Two horizontal grooves 30 are horizontally opened on the groove wall of the connecting groove 6 near the transmission rod 29, and the ends of the two transmission rods 29 away from the slider 26 respectively pass through the two horizontal grooves 30 and are respectively fixedly connected to the tops of the two vertical rods 28, and the two horizontal grooves 30 are opposite to each other up and down.

[0031] like Figure 1 and Figure 3 and Figure 4 When the two rectangular frames 7 move, the two rectangular frames 7 will drive the two sliders 26 to move closer to or farther from each other through the two vertical rods 28 and the two transmission rods 29. When the two sliders 26 move closer to each other, until the pressure plates 27 on the two sliders 26 are in contact with the side walls of the raw material, the raw material can be fixed at this time, reducing the horizontal displacement of the raw material when the progressive die body 3 is processing the raw material; When the two rectangular frames 7 move so that the first and second contact columns 5 and 24 on the two baffles 2 both contact the side walls of the raw material, the slider 26 will follow the rectangular frame 7 away from the raw material through the vertical rod 28 and the transmission rod 29, thereby releasing the fixation of the raw material. The first and second contact columns 5, 24 and the pressure plate 27 do not affect each other, and the use is simple and convenient.

[0032] like Figure 4Each of the first abutment column 5 and the second abutment column 24 is mounted on the baffle plate 2 by means of bolts, and each of the first abutment column 5 and the second abutment column 24 is coaxially provided with a first thread groove 31 at one end away from the baffle plate 2. The first screw rod 32 is threadedly connected in each first thread groove 31, and a disc 33 is coaxially provided on the side of each first screw rod 32 away from the bottom of the first thread groove 31. A first anti-skid pad 34 that contacts the side wall of the raw material is provided on the side of each disc 33 away from the first screw rod 32. The purpose of this arrangement is to drive the first screw rod 32 to rotate by rotating the disc 33. At this time, the disc 33 can be moved away from the baffle 2 through the cooperation between the first screw 32 and the first thread groove 31. At this time, the length of the first contact column 5 and the second contact column 24 can be extended to adapt to raw materials of various widths. The end of the first screw 32 close to the bottom of the first thread groove 31 is always located in the first thread groove 31. The first anti-skid pad 34 can reduce the slippage between the disc 33 and the raw material, and the use is simple and convenient.

[0033] like Figure 4 The two second screws 38 are threadedly connected to the second thread groove 37, and the second anti-skid pads 39 are provided on the sides of the two plug plates 36 that are close to each other. The purpose of this arrangement is that by rotating the second screw 38, the second screw 38 can push the plug plate 36 to move in the direction away from the bottom of the embedding groove 35 through the cooperation with the second thread groove 37. At this time, the length of the two pressing plates 27 can be extended, so that the spacing between the two pressing plates 27 can be adjusted to adapt to raw materials of various widths. The second anti-skid pads 39 can reduce the slippage between the plug plate 36 and the raw material, which is simple and convenient to use.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
