Description

Technical Field

[0001] The utility model relates to the field of feeding machinery, in particular to an automatic feeding structure of a horizontal punching machine. Background Art

[0002] A horizontal punch press Figure 1 As shown, it includes a punch body 11, a first die body 12 arranged on the punch body 11, two die cores 13 slidably connected in the first die body 12, a forming cavity 14 for placing a raw material copper rod is opened between the two die cores 13, a punching seat 15 slidably connected to the punch body 11, and a punching rod arranged on the punching seat 15. Before the punch press is punched, the copper rod needs to be inserted into the forming cavity 14, and then the punch press drives the punching seat 15 to move, so that the punching rod enters the forming cavity 14 and punches the copper rod.

[0003] When the punch press puts the copper rod into the forming cavity 14, the operator lies on the punch press body 11 and inserts the copper rod into the forming cavity 14. The manual loading method is not efficient, so an automatic loading structure needs to be designed to replace manual loading and improve the safety of punch press production. Utility Model Content

[0004] The present application provides an automatic feeding structure of a horizontal punch press, which can automatically insert a copper rod into a forming cavity.

[0005] The automatic feeding structure of a horizontal punch press provided in the present application uses the following technical solution:

[0006] An automatic feeding structure of a horizontal punch press includes a feeding device for providing copper rods and a feeding device for transporting the copper rods provided by the feeding device to the cavity mouth of a forming cavity. The feeding device includes a base, a guide slide rail installed on the base, a sliding seat slidably connected to the guide slide rail, a clamping claw provided on the sliding seat, a receiving hole opened on the clamping claw for receiving the copper rod provided by the feeding device, and a driving mechanism for driving the sliding seat to slide so that the receiving hole faces the forming cavity.

[0007] By adopting the above technical solution, before the punch press punches, the feeding device first sends the copper rod into the receiving hole, and then the driving mechanism starts to move the sliding seat, so that the claws transport the copper rod to the cavity opening of the forming cavity. Then the punch press controls the sliding seat to move toward the two mold cores. During this process, the punch rod will first contact the copper rod in the receiving hole, and then the punch rod will push the copper rod out of the receiving hole and push the copper rod into the forming cavity, thereby completing the automatic feeding of the copper rod.

[0008] Preferably, the feeding device includes a feeding platform arranged on the punch body, a feeding assembly for conveying the copper rod to the feeding platform, a positioning groove opened on the feeding platform for accommodating the copper rod, a top block slidably connected to the feeding platform for pushing the copper rod entering the feeding platform into the positioning groove, a first driving part for driving the sliding seat to move, and a second cylinder for pushing the copper rod in the positioning groove into the receiving hole.

[0009] By adopting the above technical solution, the receiving hole is directly opposite to the positioning groove before the punch press is started. After the punch press is started, the feeding assembly transports the copper rod to the feeding platform, and then the first driving unit controls the movement of the top block, which pushes the copper rod entering the feeding platform into the positioning groove, and then the piston rod driven by the second cylinder extends to push the copper rod in the positioning groove into the receiving hole, thus completing the feeding of a copper rod.

[0010] Preferably, the driving mechanism includes a first cylinder arranged on the base and a connecting block arranged on the sliding seat, the connecting block is fixedly connected to the piston rod of the first cylinder, and an opening for the punching rod to pass through is provided on the side wall of the receiving hole facing the first mold body.

[0011] By adopting the above technical solution, after the copper rod is pushed into the receiving hole, the piston rod of the first cylinder extends and moves with the connecting block. When the connecting block moves, it will move the sliding seat and the claw so that the copper rod will be transported to the cavity opening of the forming cavity. Then the sliding seat moves so that the punching rod pushes the copper rod out of the receiving hole and pushes it into the forming cavity, completing the automatic feeding of the copper rod. Then the piston rod of the first cylinder retracts and moves and resets with the sliding seat and the claw through the connecting block to prevent the claw from hitting the punching seat. When the claw moves and resets, the punching rod will detach from the receiving hole through the opening.

[0012] Preferably, the base is also provided with a reset mechanism for assisting the claw to move and reset when the copper rod is pushed out of the receiving hole. The reset mechanism includes a stopper provided on the sliding seat, a push plate rotatably connected to the machine body and used to push the stopper to move and reset, and a transmission assembly for driving the push plate to rotate. The transmission assembly is connected to the stamping seat and is used to be driven by the stamping seat to drive the push plate to rotate. An opening is provided on the side wall of the receiving hole facing the first mold body for the stamping rod to pass through.

[0013] By adopting the above technical solution, when the punching seat moves, the turntable will rotate through the transmission assembly. The rotation will hit the block to cause the claw and the sliding seat to move and reset, thereby assisting the first cylinder to reset the sliding seat and the claw, preventing the claw from colliding with the punching seat due to untimely reset.

[0014] Preferably, the transmission assembly includes a first connecting column arranged on the push plate, a second connecting column arranged on the stamping seat, and a connecting rod whose two ends are respectively hingedly connected to the first connecting column and the second connecting column, and the axis of the first connecting column and the axis of the second connecting column are both parallel to the rotation axis of the push plate.

[0015] By adopting the above technical solution, when the punching seat moves, it will move with the connecting rod. During the movement, the connection will push the push plate to rotate through the second connecting column. During the rotation of the push plate, it will collide with the block and make the block move away from the first die. After the punching machine is finished, the punching seat moves to reset and moves with the connecting rod. During the movement and reset of the connecting rod, the push plate will be pulled to reset, preparing for the next push of the block.

[0016] Preferably, the base is also provided with a limiting component for limiting the sliding of the claw toward the first mold body after the claw is reset by the reset mechanism, the limiting component includes a first limit block provided on the connecting block, a second limit block slidably connected to the base and located on the movement path of the first limit block, and a control unit for controlling the sliding of the second limit block, the first limit block conflicts with the second limit block after the claw is reset and is located on the side of the second limit block away from the first mold body.

[0017] By adopting the above technical solution, the first limit block will also move and reset during the reset process of the claw. During the reset process of the first limit block, the control unit controls the second limit block to slide, so that the second limit block does not block the reset of the first limit block. After the first limit block is reset, the control unit controls the second limit block to move so that the second limit block returns to the movement path of the first limit block, and the second limit block blocks the first limit block, thereby preventing the first cylinder from leaking and causing the sliding seat and the claw to move toward the first mold body, thereby achieving the effect of limiting the movement of the claw toward the first mold body.

[0018] Preferably, the control unit includes a third cylinder arranged on the machine body, a fixing plate arranged on the output shaft of the second cylinder, and a connecting piece for connecting the fixing plate and the second limiting block.

[0019] By adopting the above technical solution, the piston rod of the third cylinder will move with the fixed plate when it extends and retracts, and the movement of the fixed plate will slide with the second limit block through the connecting piece, thereby achieving the effect of controlling the sliding of the second limit block.

[0020] Preferably, the connecting member is a spring, both ends of which are respectively connected to a fixed plate and a second limit block, the first limit block is tilted, and the distance from the first limit block to the claw gradually increases from an end close to the first cylinder to an end far from the first cylinder.

[0021] By adopting the above technical solution, when the push plate pushes the block to move and reset, the connecting block, the claw, and the first limit block will also move away from the first mold body, thereby preventing the claw from colliding with the sliding seat. During the movement and reset of the first limit block, it will collide with the second limit block and push the second limit block to move away from the guide rail. During this process, the spring will be compressed. Later, when the first limit block no longer pushes the second limit block to move, the spring will rebound and move the second limit block to reset, so that the second limit block and the end of the first limit block close to the first mold body conflict, thereby preventing the first limit from moving toward the first mold body, and achieving the effect of limiting the movement of the claw toward the first mold body. When the piston rod of the first cylinder is extended, the piston rod of the third cylinder is extended and moves the connecting plate away from the guide rail. When the connecting plate moves, it will pull the second limit block to move toward the guide rail through the spring, so that the second limit rod no longer blocks the movement of the first limit block, so that the claw can smoothly send the copper rod to the cavity mouth of the molding cavity.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model uses a feeding device, a feeding device, and a punching rod to complete the automatic feeding of copper rods;

[0024] 2. The utility model is provided with a transmission assembly to convert the power of the sliding seat into the power of the push plate, so that the push plate can automatically rotate and push the sliding seat to move;

[0025] 3. The utility model limits the movement of the clamping claw toward the first mold body and collides with the sliding seat after the clamping claw is reset through the cooperation of the first limit block and the second limit block. BRIEF DESCRIPTION OF THE DRAWINGS

The feeding assembly 22 is a vibration plate and a connecting channel for connecting the vibration plate and the feeding platform 21. (The vibration plate is not shown in the figure).

[0035] Reference Figure 2-Figure 4The punch body 11 is also provided with a feeding device 3 for transporting the copper rod provided by the feeding device 2 to the cavity opening of the forming cavity 14. The feeding device 3 includes a base 9 provided on the punch body 11, a guide rail 31 obliquely provided on the base 9, a sliding seat 10 slidably connected to the guide rail 31 along the length direction of the guide rail 31, a clamping claw 32 provided on the end of the sliding seat 10 close to the first mold body 12, and a receiving hole 33 provided on the end of the clamping claw 32 close to the first mold body 12 for receiving the copper rod pushed out of the positioning groove 23. The end of the guide rail 31 close to the first mold body 12 is lower than the end of the guide rail 31 away from the first mold body 12. Before the punch is started, the receiving hole 33 is directly opposite to the positioning groove 23, and an opening 321 for the punching rod 16 to pass through is provided on the side wall of the receiving hole 33 facing the first mold body 12.

[0036] Reference Figure 4 The feeding device 3 also includes a driving mechanism 4 for driving the claw 32 to move so that the receiving hole 33 faces the molding cavity 14. The driving mechanism 4 includes a first cylinder 41 fixed on the base 9 and a connecting block 42 fixed on the sliding seat 10. The connecting block 42 is also fixed on the piston rod of the first cylinder 41. The first cylinder 41 is located on the side of the claw 32 away from the feeding platform 21, and the axial direction of the first cylinder 41 is parallel to the length direction of the guide rail 31.

[0037] Reference Figure 4 and Figure 5 The base 9 is also provided with a reset mechanism 5 for assisting the claw 32 to move and reset when the copper rod is pushed out of the receiving hole 33. The reset mechanism 5 includes a stopper 51 fixed on the sliding seat 10, a push plate 52 rotatably connected to the machine body and used to push the stopper 51 to move and reset, and a transmission assembly 53 for driving the push plate 52 to rotate. The transmission assembly 53 is connected to the punching seat 15 and is used to be driven by the punching seat 15 to drive the push plate 52 to rotate. The transmission assembly 53 includes a first connecting column 531 fixedly connected to the push plate 52, a second connecting column 532 fixedly connected to the punching seat 15, and a connecting rod 533 whose two ends are respectively hingedly connected to the first connecting column 531 and the second connecting column 532.

[0038] Reference Figure 4-Figure 6The base 9 is also provided with a limiting assembly 6 for limiting the claw 32 from sliding toward the first mold body 12 after the claw 32 is reset by the reset mechanism 5. The limiting assembly 6 includes a first limit block 61 fixedly connected to the connecting block 42, and a second limit block 62 slidably connected to the machine body along a length direction perpendicular to the guide rail 31. The second limit block 62 is located on the side of the rotating shaft away from the sliding seat 10. The movement path of the second limit block 62 intersects with the movement path of the first limit block 61. After the first limit block 61 follows the claw 32 to reset, it contacts the second limit block 62 and is located on the side of the second limit block 62 away from the first mold body 12. Before the punch press is started, the first limit block 61 is located on the side of the second limit block 62 away from the first mold body 12, and the second limit block 62 is located on the movement path of the first limit block 61.

[0039] Reference Figure 5 and Figure 6 The limiting assembly 6 further includes a control unit 7 for controlling the sliding movement of the second limiting block 62. The control unit 7 includes a third cylinder 71 fixed to the machine body, a fixing plate 72 fixed to the output shaft of the second cylinder 26, and a connecting member 8 for connecting the fixing plate 72 and the second limiting block 62. The connecting member 8 is a spring 81. The third cylinder 71 is located at a side of the second limiting block 62 away from the rotating shaft. One end of the spring 81 is fixedly connected to the fixing plate 72, and the other end of the spring 81 is fixedly connected to an end of the second limiting block 62 away from the guide rail 31.

[0040] Reference Figure 2-Figure 4 The automatic loading steps of the punch press in this application are as follows:

[0041] First, the vibration plate sends the copper rod to the feeding platform 21 through the connecting channel, and then the piston rod of the first driving part 25 extends to move the top block 24, and the top block 24 pushes the copper rod entering the feeding platform 21 into the positioning groove 23, and then the piston rod driven by the second cylinder 26 extends to push the copper rod in the positioning groove 23 into the receiving hole 33, thus completing the feeding of a copper rod. After the copper rod is pushed into the receiving hole 33, the piston rod of the first cylinder 41 extends, and the piston rod of the first cylinder 41 extends to move the connecting block 42, the sliding seat 10, and the claw 32, so that the claw 32 transports the copper rod to the cavity opening of the forming cavity 14.

[0042] Before the piston rod of the first cylinder 41 extends, the piston rod of the third cylinder 71 will extend and move the fixing plate 72 away from the guide rail 31. When the fixing plate 72 moves, it will pull the second limit block 62 to move toward the guide rail 31 through the spring 81, so that the second limit rod no longer blocks the movement of the first limit block 61.

[0043] After the copper rod is transported to the cavity mouth of the forming cavity 14 , the punch press controls the punch seat 15 to move toward the two mold cores 13 . During this process, the punch rod 16 will first contact the copper rod in the receiving hole 33 , and then the punch rod 16 will push the copper rod out of the receiving hole 33 and push the copper rod into the forming cavity 14 .

[0044] When the copper rod is pushed into the molding cavity 14, the piston rod of the first cylinder 41 moves and resets the connecting block 42, the first limit block 61, the sliding seat 10 and the claw 32. During the movement and reset of the first limit block 61, it will collide with the second limit block 62 and push the second limit block 62 to move away from the guide rail 31. During this process, the spring 81 will be compressed. Later, when the first limit block 61 no longer pushes the second limit block 62 to move, the spring 81 will rebound and move the second limit block 62 to reset and return to the initial position, thereby preventing the first limit block from moving toward the first mold body 12, thereby limiting the movement of the claw 32 toward the first mold body 12.

[0045] When the punching seat 15 moves, the connecting rod 533 will move with it. During the movement, the connecting rod 533 will push the push plate 52 to rotate through the second connecting column 532. During the rotation of the push plate 52, it will collide with the block 51 and make the block 51, the claw 32, and the sliding seat 10 move away from the first mold body 12. In this way, the first cylinder 41 is assisted to reset the sliding seat 10 and the claw 32 together, preventing the claw 32 from colliding with the punching seat 15 when it is not reset in time.

[0046] After the punching is completed, the sliding seat 10 moves to reset and brings the connecting rod 533 to reset. During the movement and reset of the connecting rod 533, the push plate 52 will be pulled to reset in preparation for the next push of the stopper 51.

[0047] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
