Description

Technical Field

[0001] This invention relates to the field of shaft parts production equipment, and in particular to an automatic hammer stacking integrated device for wedge cross rolling shaft parts. Background Technology

[0002] In the manufacturing process of shaft parts, the wedge rolling process uses rolls with wedge-shaped dies to roll heated metal bars to form structures such as stepped shafts. After rolling, the waste material at both ends of the parts needs to be removed and the parts stacked for storage. Currently, most equipment has a split layout: the waste material removal device and the stacking device are separate, requiring an additional conveyor structure to connect them. This layout results in excessively long production lines, occupying a large amount of space, being easily limited by factory area, and increasing equipment costs and operational complexity. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as large space requirements and susceptibility to factory area limitations, and to propose an integrated automatic hammer stacking device for wedge cross-rolled shaft parts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic hammer stacking integrated device for wedge cross-rolled shaft parts includes a fixed frame, a cylinder is mounted on the top of the fixed frame via a bracket, the end of the cylinder output shaft is fixedly connected to a mounting seat, and the mounting seat is slidably sleeved on the outer wall of the bracket.

[0006] Two hammers are used to cut off excess material at both ends of the part, and the two hammers are respectively fixedly connected to both sides of the bottom of the mounting base;

[0007] Two anvils are provided, with a workstation frame on the top of each anvil. A movable cavity is provided on the top of the fixed frame. A lifting seat is slidably connected inside the movable cavity. The two anvils are slidably connected to the two sides of the top of the lifting seat. Multiple telescopic rods are provided inside the movable cavity, and the two ends of the multiple telescopic rods are fixedly connected to the bottom inner wall of the movable cavity and the bottom of the lifting seat, respectively. A No. 1 spring is sleeved on the outer wall of the multiple telescopic rods.

[0008] The fixed plate has a sliding groove on one side of the lifting seat, and the fixed plate is slidably connected inside the sliding groove. The inner wall of one side of the movable cavity has a fixed groove, and one end of the fixed plate extends into the fixed groove. The top of the fixed plate is fixedly connected to an inclined block. The top of the lifting seat has a through hole, and the inclined block is located inside the through hole. The bottom of the mounting seat is fixedly connected to a stop plate, and the stop plate cooperates with the inclined block.

[0009] A placement cavity is located in the middle of the fixed frame. Multiple collection trays are stacked inside the placement cavity, and multiple placement racks are arranged inside the collection trays.

[0010] A push plate is slidably connected to the bottom inner wall of the placement cavity and is used to push the collection tray at the bottom.

[0011] Two collection racks are provided, with a base on one side of the fixed frame, and the two collection racks are respectively fixedly connected to the two sides of the top of the base.

[0012] In one possible design, the sidewall of the hammer head is provided with a clearance groove, which provides clearance space when the anvil moves outward.

[0013] In one possible design, inclined ramps are provided on both sides of the top of the fixed frame to allow the cut-off material to automatically roll off and be discharged.

[0014] In one possible design, a feeding channel is provided between the active cavity and the placement cavity, and multiple elastic plates are fixedly connected to the side wall of the feeding channel to cushion the falling parts.

[0015] In one possible design, the top of the lifting seat is provided with a ramp on the side near the unloading channel to guide the parts into the unloading channel after the anvil moves outward.

[0016] In one possible design, the side wall of the placement cavity is provided with a side groove, and a threaded rod is rotatably connected inside the side groove. A connecting block is threadedly sleeved on the outer wall of the threaded rod, and the connecting block is fixedly connected to one side of the push plate. The push plate is moved by rotating the threaded rod driven by a motor.

[0017] In one possible design, the side wall of the collection rack is vertically fixedly connected to multiple fixing frames. The side wall of the fixing frame is provided with a groove, and the groove is connected to an inclined plate by a No. 3 spring. The inclined plate has a downward slope. Slots are provided on both sides of the collection tray for fixing the collection tray by the inclined plate when the lifting plate lifts the collection tray.

[0018] In one possible design, the multi-section telescopic rod is coaxially arranged with the first spring, and the two ends of the first spring are respectively fixedly connected to the bottom inner wall of the movable cavity and the bottom of the lifting seat through spring seats to provide the restoring force of the lifting seat.

[0019] In one possible design, the side wall of the anvil is provided with an inclined surface, and the inner walls on both sides of the movable cavity are provided with inner grooves. The anvil and the lifting seat are connected by a second spring. When the lifting seat rises and resets, the inclined surface of the anvil contacts the top wall of the inner groove to drive the anvil to move inward and reset.

[0020] In this application, during actual use, the worker places the processed part on two workstation frames using tools such as clamps. Then, the cylinder is driven, causing the mounting base, bottom hammer, and abutment to move downwards. The hammer first touches the part, pressing it down to remove excess material from both ends. Continuing downwards, the abutment touches the inclined block, pushing it to one side. This causes the bottom fixing plate to move as well, disengaging it from the fixing groove and releasing the lifting seat from its fixed position. Further downward movement causes the lifting seat to move downwards as well. When the anvil enters the side of the inner groove, the second spring pushes the anvil, causing the two anvils on either side to move outwards and move away from each other. This causes the main body of the part to fall to the top of the lifting seat. Due to the slope at the top of the lifting seat, the part will slide outward. When the lifting seat descends to the connection point between the active cavity and the feeding channel, the part will slide into the inside of the feeding channel until it falls into the placement rack of the bottom collection tray. Then the cylinder resets, and the lifting seat will be reset by the force of the first spring. When the lifting seat resets upward, the inclined surface of the anvil will touch the top wall of the inner groove and be squeezed to reset. When the lifting seat touches the limit block at the top of the fixed frame and completes the reset, the mounting seat continues to move upward. At this time, the fixing plate will also be reset by the force of the spring, so that it is reinserted into the inside of the fixing groove to fix the lifting seat again.

[0021] Once the parts fall onto the corresponding placement rack in the collection tray, the drive motor rotates the threaded rod, which in turn moves the push plate. The push plate then moves the bottom collection tray, allowing the next placement rack inside the collection tray to move directly below the unloading channel. When the collection tray is full, it is pushed to the top of the base. Then, the drive motor moves the electric telescopic rod to move the lifting plate upwards, which in turn moves the collection tray upwards. When the collection tray touches the inclined surface of the inclined plate, it will press the inclined plate inwards. Then, the spring returns the tray to its original position, locking it into the slot and securing it. Afterward, the lifting plate and push plate return to their original positions. When the push plate moves to the side, the top collection tray will fall down. Then, the push plate is driven again to move the bottom collection tray, allowing the placement rack inside the collection tray to move directly below the unloading channel.

[0022] In this invention, the automatic hammer stacking integrated device for wedge cross-rolled shaft parts, through the cutting structure, can achieve the following: after the excess material at both ends of the part is cut off, the main body of the part can slide directly into the collection tray below it, while the waste will slide directly to the outside of the device for collection.

[0023] In this invention, the automatic hammer stacking integrated device for wedge cross-rolled shaft parts uses an elastic sheet to buffer the parts during their fall, thereby preventing damage to the parts.

[0024] In this invention, the integrated structure allows the excess material of the parts to fall directly into the collection tray below for collection after being cut off. When the collection tray is full, it can be pushed directly to the collection station on one side for stacking, thus eliminating the need for external conveyor belts or robotic arms and other transfer equipment, reducing equipment investment costs.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In one embodiment: Reference Figure 1-2An automatic hammer stacking integrated device includes: a fixed frame 1, and a cylinder 3 mounted on the top via a bracket. The output shaft end of the cylinder 3 is fixedly connected to a mounting seat 2. The mounting seat 2 is slidably sleeved on the outer wall of the bracket to form a vertical guide mechanism. Hammers 8 are fixedly connected to both sides of the bottom of the mounting seat 2. The side wall of the hammers 8 is provided with clearance grooves 9.

[0034] refer to Figure 3-5 The top of the fixed frame 1 is provided with a movable cavity 12. A lifting seat 11 is slidably arranged inside the movable cavity 12. Two anvils 21 are slidably arranged on both sides of the top of the lifting seat 11. Multiple multi-section telescopic rods 14 are provided inside the movable cavity 12. The two ends of the multi-section telescopic rods 14 are respectively fixedly arranged on the bottom inner wall of the movable cavity 12 and the bottom of the lifting seat 11. A first spring 13 is sleeved on the outer wall of the multi-section telescopic rods 14. The two ends of the first spring are respectively connected to the bottom inner wall of the movable cavity 12 and the bottom of the lifting seat 11 through spring seats.

[0035] A sliding groove is provided on one side of the lifting seat 11, and the fixing plate 27 is slidably disposed inside the sliding groove. A fixing groove 26 is provided on the inner wall of one side of the lifting seat 11, and one end of the fixing plate 27 extends into the fixing groove 26 to fix the lifting seat 11. An inclined block 25 is fixedly disposed on the top of the fixing plate 27. A through hole 24 is provided on the top of the lifting seat 11, and the inclined block 25 is located inside the through hole 24. A stop plate 4 is fixedly disposed on the bottom of the mounting base 2, and the stop plate 4 cooperates with the inclined block 25.

[0036] Specifically, the workers use tools such as clamps to place the processed parts into the workstation frame 20 on top of the two anvils 21. Then, the drive cylinder 3 drives the mounting base 2 and the hammer head 8 and the abutment plate 4 at the bottom to move downwards. The hammer head 8 touches the part first and then presses it down to cut off the excess material at both ends. The top of the fixed frame 1 is provided with inclined slides 10 on both sides. The cut-off excess material will roll down to one side through the inclined slides 10 and be collected by the collection device set on the side wall. Then, the mounting base 2 continues to move downwards, and the abutment plate 4 will touch the inclined block 25, thereby pushing it to one side, which will drive the fixed plate 27 at the bottom to move together, so that it is removed from the inside of the fixed groove 26, and the fixed state of the lifting seat 11 is released.

[0037] refer to Figure 2 and Figure 4 The side wall of the anvil 21 is provided with an inclined surface 23, and the inner walls on both sides of the movable cavity 12 are provided with inner grooves 15. The side wall of the lifting seat 11 and the side wall of the anvil 21 are provided with the same second spring 22 through the spring seat.

[0038] Specifically, after the lifting seat 11 is released from its fixed state, the mounting seat 2 continues to move downward. At this time, the lifting seat 11 will be pressed down as well. When the anvil 21 enters the side of the inner groove 15, the second spring 22 will push the anvil 21 to move, causing the two anvils 21 on both sides to move outward and move away from each other. The main body of the part will fall to the top of the lifting seat 11. Since the side wall of the hammer 8 is provided with a clearance groove 9, the workstation frame 20 will enter the clearance groove 9, thereby ensuring the displacement of the anvil 21.

[0039] refer to Figure 5 The fixed frame 1 has a placement cavity 16 in the middle, which contains multiple collection trays 18 stacked together. One side of the solid frame 1 has an operation hole connected to the placement cavity 16 for manual addition of collection trays. A push plate 28 is slidably provided on the bottom inner wall of the placement cavity 16, and a motor-driven threaded rod 17 is provided in the side groove of the placement cavity 16. A connecting block threaded onto the outer wall of the threaded rod 17 is provided on one side of the push plate 28. The motor drives the bottom collection tray 18 to move.

[0040] The active cavity 12 and the placement cavity 16 are connected through the feeding channel 29, and the inner wall of the channel is provided with an elastic sheet 30 to buffer the falling parts;

[0041] Specifically, due to the slope at the top of the lifting seat 11, the parts will slide outwards after falling to the top. When the lifting seat 11 descends to the connection point between the movable cavity 12 and the unloading channel 29, the parts will slide into the inside of the unloading channel 29. The elastic sheet 30 set on the inner wall of the channel will buffer the falling parts until they fall into the placement rack of the bottom collection tray 18. Then the cylinder 3 will reset, and the lifting seat 11 will be reset by the force of the first spring 13. When the lifting seat 11 resets upwards, the inclined surface 23 of the anvil 21 will touch the top wall of the inner groove 15 and be squeezed to reset. When the lifting seat 11 touches the limit block at the top of the fixed frame 1 and completes the reset, the mounting seat 2 continues to move upwards. At this time, the fixing plate 27 will also be reset by the force of the spring, so that it is reinserted into the inside of the fixing groove 26 to fix the lifting seat 11 again.

[0042] This application can be used in the field of shaft parts production equipment, or in other fields applicable to this application.

[0043] In another embodiment: Reference Figure 1 and Figure 6An automatic hammer stacking integrated device for wedge cross rolling shaft parts is applied to the field of shaft parts production equipment. The fixed frame 1 has a base 7 on its side, and a lifting plate 6 driven by an electric telescopic rod is vertically installed in the middle of its top. Collection racks 5 are fixed on both sides. The side wall of the fixed frame 31 is provided with a groove, and an inclined plate 32 is provided in the groove through a No. 3 spring. The inclined surface of the inclined plate 32 is downward. Slots 19 are opened on both sides of the collection tray 18.

[0044] Specifically, when a part falls onto the corresponding placement rack in the collection tray 18, the drive motor drives the threaded rod 17 to rotate. The threaded rod 17 will drive the push plate 28 to move, and the push plate 28 will push the lowest collection tray 18 to move, so that the next placement rack inside the collection tray 18 can move directly below the unloading channel 29. When the collection tray 18 is full, it is pushed to the top of the base 7. Then, the electric telescopic rod is driven to move the lifting plate 6 upward. The lifting plate 6 will move the collection tray 18 upward. When the collection tray 18 touches the inclined surface of the inclined plate 32, it will press the inclined plate 32 inward. Then, it will be reset by the spring, so that it is locked into the slot 19, thus completing the fixation of the collection tray 18. Then, the lifting plate 6 and the push plate 28 are reset. When the push plate 28 moves to the side, the upper accumulated collection tray 18 will fall down. Then, the push plate 28 is driven again to push the lowest collection tray 18 to move, so that the placement rack inside the collection tray 18 can move directly below the unloading channel 29.

[0045] The workflow is as follows: the operator uses clamps to place the wedge-rolled shaft parts into the workstation frame 20 of the two anvils 21;

[0046] Cylinder 3 drives mounting base 2 to move downwards, hammer head 8 first contacts the end of the part, and as it continues to move downwards, it cuts off the excess material at both ends;

[0047] After the abutment plate 4 contacts the inclined block 25, it pushes the fixing plate 27 to disengage from the fixing groove 26, and the lifting seat 11 continues to descend with the mounting seat 2.

[0048] After the anvil 21 enters the inner groove 15, the second spring 22 pushes the anvil 21 to move outward, and the main body of the part falls to the top of the lifting seat 11 and slides into the unloading channel 29;

[0049] After being buffered by the elastic sheet 30, the parts enter the collection tray 18. The push plate 28 pushes the bottom placement rack to the unloading station. When the tray is full, it is pushed onto the lifting plate 6 and lifted by the lifting plate 6 to the collection rack 5.

[0050] When cylinder 3 returns, spring 13 drives lifting seat 11 to rise and reset. After the inclined surface 23 of anvil 21 contacts the top wall of inner groove 15, it automatically returns to its original position, and fixing plate 27 is reinserted into fixing groove 26.

[0051] However, as is well known to those skilled in the art, the working principles and wiring methods of cylinder 3, motor and electric telescopic rod are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0052] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
