Description

Technical Field

[0001] The present invention relates to the technical field of presses, in particular to a press. Background Art

[0002] A press is a vital piece of industrial equipment used to form, stamp, and forge metal or non-metallic materials through pressure processing. Its core operating principle is to utilize pressure generated by a hydraulic or mechanical transmission system to drive a die to exert force on the material, causing it to plastically deform or separate, thereby obtaining a workpiece of the desired shape and size. Presses play an irreplaceable role in numerous fields, including automotive manufacturing, aerospace, electronics, and hardware, and are a key piece of equipment in modern industrial production lines.

[0003] The application document with publication number CN119489122A discloses a press for processing automobile parts. After the processing of the press is completed, when the pressing block rises, the air supply unit supplies air to the blowing hole. The air flow can help separate the product from the pressing block, avoiding the occurrence of mold jamming and ensuring the continuity of production. Secondly, since mold jamming is avoided, the time and manpower consumed in dealing with the mold jamming problem are reduced, thereby greatly improving production efficiency.

[0004] However, the above technical solution still has some technical problems. The air supply unit will supply air to the blowing hole only when the pressing block rises, and the product rises with the rise of the pressing block. When the product is separated from the pressing block, the product is at a certain height from the carrying platform. At this time, the product directly falls on the carrying platform, which is easy to cause damage to the product and affect the aesthetics of the product. Moreover, the air supply unit gradually blows air through the blowing hole as the pressing block rises. If the product fits tightly with the pressing block, slow blowing will easily lead to poor separation effect between the product and the pressing block, making it impossible to completely separate the product from the pressing block.

[0005] Therefore need a kind of press to solve above-mentioned technical problem. Summary of the Invention

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 13 As shown, a press of the present invention includes a press body 10, a movable crossbeam 11 that moves along the height direction of the press body 10 is provided on the press body 10, a die 12 with a hollow structure inside is connected to the bottom side of the movable crossbeam 11, a plurality of blowing holes 1201 that are connected to the inside of the die 12 are evenly opened on the bottom side of the die 12, two gas generators are symmetrically installed on the rear side of the press body 10, one of the gas generators is connected to the inside of the die 12 through a hose, and the other gas generator is connected to a blowing assembly, which is used to blow away dust and metal debris at the bottom of the press body 10, and a transient release is provided between each gas generator, the press body 10 and the die 12. Release component, the transient release component is used to make the gas generator generate a large amount of gas when the die 12 moves to the highest point, so that the gas blown out of the blowing hole 1201 can completely separate the product from the die 12. The bottom of the press body 10 is provided with two movable racks 20 that move along the length direction of the press body 10. Each movable rack 20 is connected with a material receiving buffer structure. The material receiving buffer structure is used to receive the product and move the product out of the range of the press body 10 to avoid the product falling and colliding with the bottom of the press body 10. A connecting component is provided between the press body 10, the movable crossbeam 11 and each movable rack 20. The connecting component is used to make the movable rack 20 move with the movement of the movable crossbeam 11.

[0035] When the die 12 is not performing processing operations, the material receiving buffer structure is located below the die 12. When the die 12 needs to process products, the die 12 moves downward. At this time, under the connection of the connecting assembly, the two movable frames 20 make relative motion and drive the two material receiving buffer structures to move away from the center of the press body 10. At this time, the die 12 can pass between the two material receiving buffer structures and process products, and the movable crossbeam 11 will not interfere with the material receiving buffer structure during the movement. After the processing operation of the product is completed, if the product adheres to the die 12, the die 12 moves upward. At this time, the two movable frames 20 drive the two The receiving buffer structure moves toward the center of the press body 10. When the die 12 moves to the highest position, the transient release component causes the gas generator to generate a large amount of gas in a short time, and transports the gas to the inside of the die 12. Then, the gas is ejected through the blowing hole 1201 in a short time. At this time, the gas pressure blown out by the blowing hole 1201 is relatively high. The product is completely separated from the die 12 by more and higher-pressure gas. The separated product will be received by the receiving buffer structure, and the product will be protected by the receiving buffer structure. Under the action of the receiving buffer structure, the product is moved out of the area of ​​the press body 10.

[0036] like Figure 3-Figure 4 and Figure 6-Figure 8 As shown, the material receiving buffer structure includes a plurality of buffer springs 30 connected to the top side of the movable frame 20, and the ends of the plurality of buffer springs 30 are connected to a plate-shaped magnetic element 31. The plate-shaped magnetic element 31 is in the shape of a right-angled trapezoid, and the top side of the plate-shaped magnetic element 31 is an inclined surface. The plate-shaped magnetic element 31 is a kind of magnet or electromagnet. The bottom end of the plate-shaped magnetic element 31 faces the rear of the press body 10. The top side of the plate-shaped magnetic element 31 is connected to a support bracket 32. A plurality of rollers are rotatably arranged on the support bracket 32, and a protective cover 33 is connected to the outer surface of each roller. The bottom side of the plate-shaped magnetic element 31 is connected to a plurality of second guide rods 34 with a T-shaped cross-section. The second guide rod 34 passes through the movable frame 20 and is slidably connected to the movable frame 20. A portion of the second guide rod 34 is located inside the buffer spring 30, and the second guide rod 34 corresponds one-to-one to the buffer spring 30. A damper 35 connected to the plate-shaped magnetic element 31 is installed on the top side of the movable frame 20.

[0037] After the product is separated from the die 12, the product will fall on the support frame 32 and contact the protective cover 33. At this time, the height of the product falling is small and the protective cover 33 prevents the product from being damaged. If the product is heavy, the buffer spring 30 and the damper 35 can buffer the product to better prevent the product from being damaged. When the product falls on the support frame 32, it will move downward under the action of gravity. At this time, the roller drives the protective cover 33 to rotate, so as to better convey the product and move the product downward. A conveyor belt is provided on one side of the press body 10. The end of the conveyor belt corresponds to the bottom end of the support bracket 32, so that the products that fall from the support bracket 32 ​​can be directly transported by the conveyor belt, avoiding the need for manual labor to catch the fallen products, reducing the labor intensity of the operators, and manually inspecting the products transported on the conveyor belt separately to determine whether the products on the conveyor belt have defects, and the hose connected to the die 12 is located at the edge of the press body 10, avoiding the material receiving buffer structure from being blocked by the hose when moving the product to the conveyor belt, so that the product can be smoothly moved from the material receiving buffer structure to the conveyor belt.

[0038] It should be noted that there is a gap between the plate-shaped magnetic element 31 and the support bracket 32 ​​to prevent the protective cover 33 from interfering with the plate-shaped magnetic element 31 during rotation, so that the roller can drive the support bracket 32 ​​to rotate smoothly. The material of the protective cover 33 is sponge, rubber or other materials with buffering function to protect the product. The conveying surface of the conveyor belt is at the same height as the bottom end of the support bracket 32 ​​to prevent the product from being damaged when it falls onto the conveyor belt.

[0039] like Figures 1-6 and Figure 10-12The gas generator includes a gas generating tank 13 installed on the rear side of the press body 10. The interior of the gas generating tank 13 is slidably connected to a piston 14. The top side of the piston 14 is fixedly connected to a piston rod 15. The piston rod 15 passes through the top of the gas generating tank 13 and is slidably connected to the gas generating tank 13.

[0040] The transient release assembly includes a ejection wedge 16 installed on the rear side of the press body 10, a pressing rod 17 connected to the die 12, and a support block 18 installed on the rear side of the press body 10. The support block 18 is located at the top position of the press body 10, and the pressing rod 17 corresponds to the position of the ejection wedge 16. The length of the pressing rod 17 is less than the minimum distance between the die 12 and the ejection wedge 16 to avoid interference between the pressing rod 17 and the ejection wedge 16 during movement. A force storage spring 19 is fixedly connected to one side of the support block 18, and the bottom end of the force storage spring 19 is fixedly connected to a movable block 110 connected to the piston rod 15. The length direction of the movable block 110 is perpendicular to the height direction of the press body 10. The interior of the movable block 110 is a hollow structure. The interior of the movable block 110 is provided with a sliding wedge 111 that moves along the length direction of the movable block 110. The sliding wedge 111 is fixed to the ejection wedge 16. The position of the material wedge 16 corresponds to that of the material pushing wedge 16, and the material pushing wedge 16 is located above the sliding wedge 111. The inclined surface of the sliding wedge 111 is parallel to the inclined surface of the material pushing wedge 16, and the sliding wedge 111 corresponds to the position of the pressing rod 17. One side of the sliding wedge 111 is fixedly connected to the first guide rod 112, and the first guide rod 112 passes through the movable block 110 and is slidably connected to the movable block 110. The outer surface of the first guide rod 112 is sleeved with a return spring 113, and the return spring 113 is located inside the movable block 110. One end of the return spring 113 fits against the inner wall of the movable block 110, and the other end of the return spring 113 contacts the sliding wedge 111. The outer surface of the first guide rod 112 is threadedly connected to the limiting nut 114, and the limiting nut 114 is located outside the movable block 110. The limiting nut 114 is used to limit the sliding wedge 111 from being completely separated from the movable block 110.

[0041] Before the product is processed, the pressing rod 17 is located above the sliding wedge 111. When the die 12 descends to process the product, the pressing rod 17 descends accordingly. When the pressing rod 17 fits the inclined surface of the sliding wedge 111, the sliding wedge 111 will be retracted into the interior of the movable block 110 as the pressing rod 17 descends. At this time, the return spring 113 is in a compressed state. As the pressing rod 17 descends and the sliding wedge 111 moves, the pressing rod 17 can move to the bottom of the sliding wedge 111. When the pressing rod 17 moves to the bottom of the sliding wedge 111, the return spring 113 will cause the sliding wedge to be retracted. 111 resets and blocks the pressing rod 17. When the work of processing the product is completed, the die 12 rises. At this time, the pressing rod 17 is in contact with the bottom side of the sliding wedge 111 and drives the sliding wedge 111 to move upward. At this time, the sliding wedge 111 moves upward and squeezes the storage spring 19, so that the storage spring 19 is in a state of storage, and the sliding wedge 111 drives the piston rod 15 and the piston 14 to move upward. When the sliding wedge 111 moves upward to a position in contact with the ejecting wedge 16, the inclined surface of the sliding wedge 111 is in contact with the inclined surface of the ejecting wedge 16, and as the pressing rod 17 rises, and through the ejecting wedge 16 blocks the sliding wedge 111. At this time, under the action of the top wedge 16 and the inclined surface of the sliding wedge 111, the sliding wedge 111 is retracted into the interior of the movable block 110 and squeezes the return spring 113. When the sliding wedge 111 is separated from the pressing rod 17, as the pressing rod 17 rises, the pressing rod 17 moves to the top of the sliding wedge 111. At this time, the pressing rod 17 no longer blocks the sliding wedge 111. Under the reaction force of the storage spring 19, the movable block 110 moves downward rapidly. As the movable block 110 moves downward, the piston rod 15 drives the piston 14 to move downward rapidly and the gas generating tank 1 3. Gas is generated quickly. The gas generated in a gas generating tank 13 enters the interior of the die 12 and is blown out from the blowing hole 1201. Since the gas is generated quickly, the flow rate of the gas blown out from the blowing hole 1201 and the pressure exerted by the gas on the product are relatively large, thereby ejecting the product adhering to the die 12 and separating it from the die 12. The gas generated in a gas generating tank 13 enters the interior of the blowing assembly, thereby performing a blowing operation on the bottom of the press body 10, thereby blowing away the dust and metal debris at the bottom of the press body 10, and preventing the dust and metal debris from affecting the processing quality of the next product.

[0042] If the elasticity of the return spring 113 is reduced or damaged, the limiting nut 114 is separated from the first guide rod 112. At this time, the sliding wedge 111 and the first guide rod 112 can be separated from the movable block 110. Then the return spring 113 can be taken out from the inside of the movable block 110 and a new return spring 113 can be placed inside the movable block 110. Then the first guide rod 112 is passed through the inside of the return spring 113 and the sliding wedge 111 is entered into the inside of the movable block 110. Finally, the limiting nut 114 is threadedly connected to the first guide rod 112, and the limiting nut 114 is fit with the movable block 110. At this time, the sliding wedge 111 is stably maintained inside the movable block 110, thereby completing the operation of replacing the return spring 113, making the operation of replacing the return spring 113 relatively simple.

[0043] It should be noted that the end shape of the sliding wedge block 111 is arc-shaped, which facilitates the movement of the pressing rod 17 to the top or bottom of the sliding wedge block 111. A limiting rod is fixedly connected to the top side of the support block 18 and the movable block 110, and the limiting rod is located inside the force storage spring 19. The length of the limiting rod is less than the length of the force storage spring 19, which can avoid the force storage spring 19 from bending during the compression process, and the bottom of the gas generating tank 13 is a tapered design, which can speed up the flow of gas.

[0044] The press body 10 includes a frame 101, the top of the frame 101 is connected to a fixed beam 102, a driving member is installed inside the fixed beam 102, the driving member is connected to the die 12, and the driving member is used to drive the die 12 to move up and down. The bottom of the frame 101 is connected to a processing table 103, and a mounting groove 1031 is provided on one side of the processing table 103. The mounting groove 1031 passes through the processing table 103, and the length direction of the mounting groove 1031 is parallel to the length direction of the processing table 103.

[0045] It should be noted that the movable frame 20 is U-shaped, and a portion of the movable frame 20 is located inside the mounting groove 1031 , and a portion of the movable frame 20 is located above the processing table 103 , ensuring that the movable frame 20 can move smoothly.

[0046] like Figure 6-Figure 8The connecting assembly includes a mounting bracket 40 mounted on the inner wall of the mounting groove 1031 and a guide wheel 1 41 mounted on the frame 101. The mounting bracket 40 is in the shape of a U. A limited sliding groove is provided on one side of the mounting bracket 40. The inner wall of the limited sliding groove is fixedly connected to a limited sliding rod 42 and a return spring 2 43. The outer surface of the limited sliding rod 42 is slidably connected to a slide 44 connected to the return spring 2 43. The shape of the slide 44 is Π-shaped. The slide 44 is slidably connected to the limited sliding groove. The movable frame 20 is connected to one side of the slide 44 and is rotatably provided with two guide wheels 2 45 at the end of the slide 44. One side of the slide 44 is connected to a connecting rope 46. The end of the connecting rope 46 away from the slide 44 is connected to the movable crossbeam 11. The connecting rope 46 passes between the two guide wheels 2 45 and is connected to the guide wheel 2 45 through sliding friction transmission. The connecting rope 46 is connected to the guide wheel 1 41 through sliding friction transmission. The guide wheel 1 41 and the guide wheel 2 45 are used to change the direction of the connecting rope 46.

[0047] During the downward movement of the movable crossbeam 11, under the action of guide wheel 1 41, guide wheel 2 45 and connecting rope 46, the slide 44 drives the movable frame 20 to move away from the center of the mounting frame 40, thereby causing the material receiving buffer structure to move away from the center of the mounting frame 40 and provide space for the die 12 to move downward and process the product. At this time, the slide 44 will squeeze the reset spring 2 43. After the processing of the product is completed, the movable crossbeam 11 will rise. At this time, under the reaction force of the reset spring 2 43, the slide 44 will drive the movable frame 20 and the material receiving buffer structure to reset, so as to receive the product. During the movement of the movable frame 20, the plate-shaped magnetic element 31 will absorb the metal debris on the processing table 103, which greatly avoids the influence of the debris on the subsequent processing of the product.

[0048] like Figure 10-12 The blowing assembly includes a diverter pipe 50 installed on one side of the frame 101. The length direction of the diverter pipe 50 is parallel to the length direction of the press body 10. A plurality of blowing nozzles 51 are evenly connected to the outer surface of the diverter pipe 50. The blowing nozzles 51 correspond to the top position of the processing table 103. The diverter pipe 50 is connected to the bottom end of a gas generating tank 13 through a pipeline.

[0049] When gas is generated inside the gas generating tank 13, the gas is transported to the inside of the diversion pipe 50 through a pipeline, and then sprayed out through multiple blowing nozzles 51. The gas sprayed by the blowing nozzles 51 performs a blowing and cleaning operation on the top side of the processing table 103, so that the dust and metal debris are separated from the processing table 103, avoiding the influence of dust and metal debris on the next product, and ensuring the quality of the processed product.

[0050] like Figure 1-Figure 2 and Figure 4-Figure 5A plurality of scrapers 60 are installed on two symmetrical sides of the processing table 103. The positions of the scrapers 60 and the plate-shaped magnetic elements 31 correspond to each other. The blade lines of the scrapers 60 are coplanar with the bottom sides of the plate-shaped magnetic elements 31 and are parallel to the horizontal plane. A collection box 61 is provided on two symmetrical sides of the processing table 103. The collection box 61 is located below the scrapers 60.

[0051] When the plate-shaped magnetic element 31 absorbs metal debris and processes the next product, the movable frame 20 drives the plate-shaped magnetic element 31 to move away from the center of the press body 10. When the plate-shaped magnetic element 31 moves to the position of the scraper 60, the scraper 60 will scrape the metal debris absorbed on the plate-shaped magnetic element 31, and the scraped metal debris will enter the interior of the collection box 61 for collection, ensuring that the plate-shaped magnetic element 31 has a better effect in absorbing metal debris next time.

[0052] like Figure 1 、 Figure 5 and Figure 10 A guide assembly is provided between the movable block 110 and the frame 101, and the guide assembly is used to move the movable block 110 in the vertical direction. The guide assembly includes a guide slider 115 connected to the movable block 110 and a guide slide 1011 opened on the rear side of the frame 101. The guide slider 115 is located inside the guide slide 1011 and is slidably connected to the guide slide 1011. The guide slider 115 and the guide slide 1011 are both T-shaped.

[0053] like Figure 13 As shown, the drive element includes a rotating shaft 70, two flywheels 71, and a crank mechanism 72. The rotating shaft 70 is rotatably mounted within the fixed crossbeam 102. The two flywheels 71 are disposed at either end of the rotating shaft 70. The two flywheels 71 are capable of drivingly connecting to a double-headed motor. The double-headed motor has two synchronously rotating motor output shafts, one on each side of the motor. The output shaft of the double-headed motor is provided with a first pulley, which is drivingly connected to the flywheels 71, thereby achieving synchronous high-speed rotation of the two flywheels 71 by a single motor. The crank mechanism 72 is disposed on the outer circumference of the rotating shaft 70 and is connected to the die 12 to convert the high-speed rotation of the flywheels 71 into intermittent up and down motion of the slider. This conversion method ensures the stability and reliability of the movement of the die 12.
