Description

Technical Field

[0001] The present invention relates to the technical field of workpiece punching, and more specifically, to a die forging punching device with a workpiece pushing function. Background Art

[0002] Die forging punching is a plastic processing technology that uses a die to form holes in a metal blank and is an important branch of die forging technology. This technology enables the blank to undergo plastic deformation at high or room temperature through the precise cooperation of the die and high pressure, ultimately forming a hole structure with a specific shape and size.

[0003] During the process of pushing a die forging, the existing processing method is as Figures 13 - 14 shown. A hydraulic rod 310 is arranged on the side of the lower die, and a V-shaped frame 330d is arranged at the end of the hydraulic rod 310. The hydraulic rod 310 is used to push the V-shaped frame 330d to impact the die forging, and the die forging is struck and pushed away to the conveying area. This method has the following problems:

[0004] First, since both the die forging and the clamping plate are made of metal, the hydraulic rod 310 pushing the clamping plate will generate a certain amount of power, resulting in wear at the contact position when the two collide. For a die forging with a relatively thin outer wall, excessive impact may even cause dents, affecting the subsequent processing effect;

[0005] Second, the die forging after impact will generate dynamic potential energy. Under this dynamic action, the die forging will fly out of the forming area and collide with the conveying area for the second time, and it is easy to have an error in the dropping position of the die forging due to different impact positions. Some die forgings will bounce back to the upper die processing area or even pop out of the conveying area, requiring manual secondary processing;

[0006] Third, since the path after impact will deviate, different die forgings will have different transmission directions after dropping to the conveying area, resulting in the die forgings finally completed for conveying being scattered in the collection area, requiring manual secondary placement, which affects the subsequent processing efficiency.

[0007] In order to address the above problems, there is an urgent need for a die forging punching device that can achieve stable movement of die forgings. Summary of the Invention

[0008] The purpose of the present invention is to provide a die forging punching device with a workpiece pushing function to solve the problems raised in the above background art.

[0009] To achieve the above purpose, a die forging punching device with a workpiece pushing function is provided, including an upper template, a lower template, and a sliding plate installed on the side of the lower template. A clamping arm is arranged at a position on the other side of the lower template opposite to the opening of the sliding plate;

[0010] The clamping arm includes a hydraulic rod, a connecting rod, and an outer clamping plate. Outer supporting plates are movably connected to both sides of the outer clamping plate, and a clamping assembly is movably connected to the inner end thereof. An adjustment column is connected between the clamping assembly and the inner side of the connecting rod, and a limiting assembly for limiting the position of the adjustment column is arranged on the outer side of the connecting rod.

[0011] After the die forging and punching work is completed, the hydraulic rod pushes the connecting rod to approach the position of the sliding plate. When the outer clamping plate reaches the clamping position, under the action of the limiting assembly, the clamping assembly is driven by the cooperation of the adjustment column to contract towards the inner side of the outer clamping plate, forming a clamping cavity with the outer supporting plate that simultaneously approaches the die forging. During the continuous movement, the clamping cavity is reduced, and the fixed die forging is synchronously moved to the opening position of the sliding plate. Under the action of the limiting assembly, the clamping assembly and the outer supporting plate at the current position are reset, and the die forging in the fixed state is slowly pushed to the conveying position at the inner end of the sliding plate.

[0012] As a further improvement of this technical solution, the clamping assembly includes an inner shaft fixed at the end position of the adjustment column. Inner supporting plates are hinged on both sides of the inner shaft, and main torsion springs are arranged at the hinged positions between the inner supporting plates and the inner shaft and between the outer supporting plates and the outer clamping plate.

[0013] As a further improvement of this technical solution, the limiting assembly includes an outer ring and a pair of limiting rods arranged on both sides of the inner end of the outer ring. The outer ring is sleeved on the outer side of the connecting rod. The adjustment column slides along the inner side of the outer ring, and side grooves for the limiting rods to slide are formed on both sides of the connecting rod. The limiting rods pass through the side grooves and contact the side surface of the adjustment column. A limiting ring is arranged near the middle position on the outer side of the adjustment column.

[0014] As a further improvement of this technical solution, an inner sleeve is arranged at the inner end of the connecting rod. One end of the adjustment column extends into the inner end position of the inner sleeve, and a spring is connected between the inner end of the inner sleeve and the end of the adjustment column. After the limiting ring is limited by the limiting rod, it extends into the inner end along the port position of the inner sleeve and compresses the spring.

[0015] As a further improvement of this technical solution, the outer clamping plate is in a V-shaped structure, and the opening direction of the outer clamping plate faces the forming area.

[0016] As a further improvement of this technical solution, a pair of sliding rods are arranged near the bottom port position at the inner end of the sliding plate, and the two sliding rods are arranged in parallel to form a space for guiding the movement of the die forging.

[0017] As a further improvement of the technical solution, inner rotating rods and outer rotating rods are respectively arranged on both sides of the inner end of the sliding plate near the top port position. The inner rotating rod and the outer rotating rod are both connected to the inner end of the sliding plate by rotating shafts. In the non-loaded state, the inner rotating rod and the outer rotating rod are parallel to each other to form a gap, and the width of the gap is greater than the opening size of the outer clamping plate and less than the opening size formed by the two outer supporting plates when they are parallel to the outer clamping plate.

[0018] As a further improvement of the technical solution, a secondary torsion spring is connected between the rotating shaft and the inner end of the sliding plate.

[0019] As a further improvement of the technical solution, after the sides of the outer rotating rod and the inner rotating rod come into contact with the two outer supporting plates in a parallel state, the opening formed at the top is at the maximum value, and the opening size formed at the bottom is exactly the same as the interval size formed by the two sliding rods.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the die forging punching equipment with the function of workpiece pushing, by controlling the forward and reverse position movement of the two inner supporting plates, the adaptive angle adjustment of the two outer supporting plates is carried out, and when moving to contact the die forging along with the connecting rod, the outer supporting plates are controlled to contract inward, and cooperate with the outer clamping plate to clamp the die forging at the inner side position of the outer clamping plate, so that it can move to the conveying position stably and slowly along with the outer clamping plate, realizing the non-damaging pushing work of the die forging. At the same time, the outer supporting plate during the reset process cooperates with the inner rotating rod and the outer rotating rod to form a transportation channel with a wider top and a narrower bottom, guiding and straightening the die forging, so that it can maintain the same sliding direction for transportation work, ensuring that each die forging can maintain the same state to achieve the transportation work and improving the later processing efficiency.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figure 1As shown in the figure, a die forging and punching device with a workpiece pushing function is provided, including an upper template 10, a lower template 20, and a sliding plate 40 installed on the side of the lower template 20. A clamping arm 30 is arranged at a position on the other side of the lower template 20 opposite to the opening of the sliding plate 40.

[0044] The clamping arm 30 includes a hydraulic rod 310 for driving, a connecting rod 320 arranged at the front end of the hydraulic rod 310, and an outer clamping plate 330 fixed at the end position of the connecting rod 320. Outer supporting plates 331 are movably connected to both sides of the outer clamping plate 330, and a clamping component is movably connected to the inner end thereof. A positioning column 340 is connected between the clamping component and the inner side of the connecting rod 320. The clamping component includes an inner shaft 341 and a pair of inner supporting plates 342 hinged at both ends of the inner shaft 341. At the same time, in order to cooperate with the inner supporting plates 342, outer supporting plates 331 are hinged at both ends of the outer clamping plate 330. The end of the inner supporting plate 342 is attached to the side of the outer supporting plate 331, and main torsion springs are arranged at the hinged positions of the outer supporting plate 331 and the outer clamping plate 330 and the hinged positions of the inner supporting plate 342 and the inner shaft 341. A limiting component for limiting the position of the positioning column 340 is arranged on the outer side of the connecting rod 320. The limiting component includes a limiting ring 343 sleeved on the outer side of the connecting rod 320, and the outer ring 350 is fixed at the top position of the upper template 10 through a plate-like structure at the bottom end. Limiting rods 351 inclined towards the position close to the inner sleeve 322 are arranged at both inner ends of the outer ring 350. The connecting rod 320 is connected to the front end of the hydraulic rod 310 and moves left and right synchronously with the front end of the hydraulic rod 310. The connecting rod 320 passes through the inner end of the outer ring 350 and moves left and right. The inside of the connecting rod 320 is of a hollow structure. A hollow inner sleeve 322 is arranged at one end of the connecting rod 320 close to the hydraulic rod 310. A spring is arranged at the inner end of the inner sleeve 322. One end of the positioning column 340 extends into the inner end of the inner sleeve 322 and contacts the spring, and the other end is hinged to the middle position of the inner shaft 341, driving the inner supporting plate 342 to realize the functions of contraction and expansion.

[0045] After the die forging and punching work is completed, the hydraulic rod 310 pushes the connecting rod 320 towards the sliding plate 40. In the initial state, the clamping component is in an extended state. When the outer clamping plate 330 reaches the clamping position, under the action of the limiting component, the clamping component is driven by the positioning column 340 to contract towards the inner side of the outer clamping plate 330, forming a clamping cavity with the outer supporting plate 331 that moves towards the forging synchronously. During the continuous movement, the clamping cavity is reduced, and the fixed forging is synchronously moved to the opening position of the sliding plate 40. Under the action of the limiting component, the clamping component and the outer supporting plate 331 at the current position are reset, and the forging in the fixed state is slowly pushed to the inner end conveying position of the sliding plate 40.

[0046] During the process of die forging and punching, the metal blank is transported to the forming area at the top of the lower template 20 by the clamping mechanism. Using stamping technology, the upper template 10 is pushed towards the lower template 20, and the metal blank is stamped into the forming hole at the top of the lower template 20. Finally, the formed die forging is pushed out of the forming hole by the lifting mechanism built into the lower template 20.

[0047] After the forming work is completed, the die forging needs to be pushed away from the forming area for subsequent die forging and punching work of the metal blank. During this process, in order to reduce damage to the die forging, this solution uses a clamping working method for pushing. The hydraulic rod 310 arranged on the side of the forming area of the lower template 20 drives the connecting rod 320 to move synchronously towards the position of the die forging. The outer clamping plate 330 arranged at the end of the connecting rod 320 will contact the die forging in advance. Since the outer clamping plate 330 is of a V-shaped structure, and the opening of the V-shaped structure faces the position of the die forging, and the width formed by the opening is greater than the diameter of the die forging, it can wrap around both sides of the die forging when contacting.

[0048] To further ensure the stable effect during the clamping and pushing process, a movable clamping component is arranged inside the outer clamping plate 330, such as Figures 2 - 3 shown. In the initial state, the inner support plate 342 uses the elastic force provided by the main torsion spring to drive it to move towards the end position of the outer support plate 331 and move along the inner wall of the outer support plate 331, overcoming the elastic force generated by the main torsion spring between the outer clamping plate 330 and the outer support plate 331, making the outer support plate 331 parallel to the end position of the outer clamping plate 330. The included angle formed by the entire outer clamping plate 330 and the two inner support plates 342 is at the maximum value to provide sufficient space to contact the die forging.

[0049] Furthermore, the entire moving clamping process includes the following processes.

[0050] The first process: as Figure 5 shown, the hydraulic rod 310 drives the connecting rod 320 to move towards the position close to the die forging. Since the outer clamping plate 330 is located at the end of the connecting rod 320, the opening area of the outer clamping plate 330 will contact the die forging first. And when the connecting rod 320 is in a moving state, it will synchronously drive the position-adjusting column 340 to move. This is because the inner end of the connecting rod 320 is a hollow structure, the position-adjusting column 340 extends into the inner end of the inner sleeve 322 and is sleeved with the inner end of the connecting rod 320 inside it. A spring is arranged at the inner end of the connecting rod 320. Under the elastic force of the spring, the position-adjusting column 340 is maintained in a fixed state of being sleeved with the inner end of the inner sleeve 322, so that the position-adjusting column 340 can cooperate with the two inner support plates 342 to achieve position limitation and statically follow the outer clamping plate 330 to move closer to the die forging synchronously.

[0051] The second process: During the moving and extending process of the connecting rod 320, its outer side will pass through the limiting component. From Figure 4As shown in the figure, in order to cooperate with the sliding of the limit rod 351, side grooves 321 for the free sliding of the limit rod 351 are provided on both corresponding sides of the two ends of the connecting rod 320. The limit rod 351 passes through the side grooves 321 and contacts the side wall of the positioning column 340 in the moving state. A limit ring 343 is provided near the middle position on the outer side of the positioning column 340, and the limit ring 343 protrudes from the outer surface of the positioning column 340. During the synchronous movement of the positioning column 340, the limit ring 343 will gradually approach the end of the limit rod 351 until they contact each other, as Figure 6 shown. The limit rod 351 in the fixed state will limit the limit ring 343, so that the positioning column 340 cannot continue to move synchronously with the connecting rod 320.

[0052] The third process: as Figure 7 shown. The positioned positioning column 340 will slide relative to the connecting rod 320. The inner support plate 342 at the inner end of the outer clamping plate 330 is pulled by the positioning column 340, so that it contracts towards the inner side of the outer clamping plate 330 and gradually disengages from the side position of the outer support plate 331. At this time, the entire outer clamping plate 330 has moved to a position near the forging. The two outer support plates 331 are respectively located on both sides of the forging. When the side surface of the outer support plate 331 is completely disengaged from the inner wall of the outer support plate 331, the outer support plate 331 without external force will be driven by the main torsion spring to bend towards the center position of the forging and wrap around the outside of the forging. The forging will move synchronously with the wrapped outer support plate 331 towards the slide plate 40 and be pushed out of the forming area.

[0053] The fourth process: as Figure 8 shown. Since the positioning column 340 is limited by the limit rod 351, one end of the positioning column 340 will extend into the inner end of the inner sleeve 322 and squeeze the spring at its inner end, overcoming the elastic force of the spring and moving towards its inner end, synchronously driving the two inner support plates 342 to move towards the inner side of the outer clamping plate 330. Since the inner side dimension of the outer clamping plate 330 gradually decreases from the outside to the inside, the included angle formed by the two inner support plates 342 in the moving state will gradually decrease, and the end positions of the two inner support plates 342 will gradually approach the side wall position of the forging. As Figure 9 shown, the ends of the inner support plates 342 are attached to the side surface of the forging, and cooperate with the outer support plates 331 to clamp and fix the forging at multiple positions, further providing the stability during its clamping and pushing process.

[0054] Fifth process: As the positioning post 340 further moves inward towards the inner end of the inner sleeve 322, the limiting ring 343 and the contacting limiting rod 351 will reach the position of the port of the inner sleeve 322 together. Since the cross-sectional dimension of the limiting ring 343 is smaller than that of the inner end of the inner sleeve 322, the limiting ring 343 can enter the inner end through the port of the inner sleeve 322. However, the limiting rod 351 is connected to the inner side of the outer ring 350, and the formed cross-section will prevent it from entering the inner end of the inner sleeve 322. Moreover, the limiting rod 351 is an elastic structure. When it contacts the port position of the inner sleeve 322, it will be squeezed by the port, causing it to deform and disengage from the side position of the limiting ring 343 and slide along the outer side of the inner sleeve 322. Without the external force acting on the limiting ring 343, the spring compressed by the force at the inner end of the inner sleeve 322 will drive the positioning post 340 to slide outward in the reverse direction. At this time, the entire connecting rod 320 is still in a moving state. During the movement, the positioning post 340 will move in the same direction as the outer clamping plate 330, and its moving speed exceeds that of the connecting rod 320. Therefore, the positioning post 340 moving in the same direction will drive the two inner supporting plates 342 to extend outward towards the outer side of the outer clamping plate 330 and gradually approach the inner wall positions of the two outer supporting plates 331, pushing them back to the parallel state. At this time, the die forging has reached the port position of the slide plate 40 following the outer clamping plate 330.

[0055] After completing the clamping work, the die forging needs to be pushed to the transmission area. As Figure 10 shown, when the die forging has not reached the port of the slide plate 40, the inner rotating rod 420 and the outer rotating rod 430 provided at the top port position of the slide plate 40 are in a parallel state, and the gap width between them is the same up and down. At the same time, a pair of parallel sliding rods 410 are provided at the bottom port position of the slide plate 40, and the interval width formed between the two sliding rods 410 is smaller than the gap width when the inner rotating rod 420 and the outer rotating rod 430 are parallel. When the outer clamping plate 330 moves to the port position of the slide plate 40 following the connecting rod 320, the outer supporting plates 331 at both ends of the outer clamping plate 330 extend outward under the action of the inner supporting plates 342, and the two outer supporting plates 331 respectively squeeze the inner rotating rod 420 and the outer rotating rod 430. Both the inner rotating rod 420 and the outer rotating rod 430 are connected to the slide plate 40 by rotating shafts, and auxiliary torsion springs are provided at the positions of the rotating shafts. After being squeezed, the inner rotating rod 420 and the outer rotating rod 430 will move away from each other near the top port position and approach each other near the bottom port position. As Figures 11 - 12As shown, a transportation channel with a wider upper part and a narrower lower part is formed. When the outer supporting plate 331 is completely parallel to the outer clamping plate 330, the gap width formed at the top of the inner rotating rod 420 and the outer rotating rod 430 reaches the maximum value, and the die forging will lose its clamping state. Under the push of the outwardly extending inner supporting plate 342, it will break away from the inner side of the outer clamping plate 330 and then be pushed into the top area of the transportation channel with a wider upper part and a narrower lower part. Subsequently, it will slide down from top to bottom along the transportation channel to the inner end of the interval formed by the two sliding rods 410. The role of the transportation channel is to guide the pushed-away die forgings to prevent blockage, and at the same time, it can smoothly gather the die forgings to the middle area of the gap, straighten the position of the die forgings, and slide along the interval, thereby improving the conveying effect of the die forgings.

[0056] The present invention controls the forward and reverse position movement of the two inner supporting plates 342, makes an adaptive angle adjustment to the two outer supporting plates 331, and controls the inward contraction of the outer supporting plate 331 when it moves in contact with the position of the die forging following the connecting rod 320. It cooperates with the outer clamping plate 330 to clamp the die forging at the inner side position of the outer clamping plate 330, enabling it to move stably and slowly to the conveying position following the outer clamping plate 330, realizing the non-damaging pushing work of the die forging. At the same time, the outer supporting plate 331 during the reset process cooperates with the inner rotating rod 420 and the outer rotating rod 430 to form a transportation channel with a wider upper part and a narrower lower part, guiding and straightening the die forging, enabling it to maintain the same sliding direction for transportation work, ensuring that each die forging can maintain the same state to achieve the transportation work, and improving the later processing efficiency.
