Abstract
Description
Technical Field
[0001] This utility model relates to a hydraulic punching machine, specifically an automatic material feeding hydraulic punching machine. Background Technology
[0002] Hydraulic punching is a process that uses the pressure of a hydraulic system to drive a punch to process materials and create holes. Hydraulic punching machines use the pressure of hydraulic oil to advance the cutting tool, thus punching holes in the material. Compared to traditional mechanical punching machines, hydraulic punching machines offer higher processing precision and greater adaptability, capable of handling metal sheets of different materials and thicknesses.
[0003] Hydraulic punching machines punch holes in sheet metal. The discharge method varies depending on the thickness of the sheet metal.
[0004] For thicker sheets, robotic arms are often used for material handling and unloading; while for thinner sheets, pneumatic devices are often used.
[0005] Common pneumatic devices include an air blowing module and a suction module. By blowing high-speed air onto the sheet material, the sheet material is separated from the mold, and then the suction module picks it up, thereby achieving automatic material discharge.
[0006] Because the punched holes in the sheet metal will deform under the pressure of the mold (protruding into the mold hole), the sheet metal and the mold will stick together. The bonding strength between the two is proportional to the deformation. However, the deformation is difficult to monitor in real time during processing. Therefore, when using a pneumatic device for material discharge, it is difficult to separate the sheet metal from the mold when the blowing air velocity is relatively low. When the blowing air velocity is high, although the sheet metal can be separated from the mold, the sheet metal is easily blown away, which may cause the sheet metal to collide with the mold, easily damaging the mold and affecting the surface quality of the sheet metal. Utility Model Content

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0047] Please see Figures 1-8 As an embodiment of this utility model, the automatic material discharge hydraulic punching machine includes a machine housing 1; a hydraulic stamping module 2 and a base plate 3 are fixedly installed on the machine housing 1; a top plate 201 is fixedly installed on the side of the hydraulic stamping module 2 facing the base plate 3;
[0048] The casing 1 is provided with a discharge ramp 101;
[0049] The suspended component, which is set on the base plate 3, includes multiple sets of fixed clamping blocks 501 and sliding clamping blocks 601 for clamping the plate and moving the plate away from or close to the base plate 3;
[0050] It also includes a material ejector, which is rotatably mounted on the base plate 3, including a lever 19; when the suspended component is activated, it can drive the lever 19 to rotate, so as to push the plate to move towards the unloading ramp 101.
[0051] In this embodiment, an upper punching die is fixedly installed on the top plate 201; a lower die that cooperates with the upper punching die is fixedly installed on the bottom plate 3; the hydraulic stamping module 2 can drive the top plate 201 to move closer to or further away from the bottom plate 3; thereby driving the upper and lower dies to cooperate with each other to complete the punching operation on the sheet metal.
[0052] During processing, the sheet metal is placed on the sliding clamping block 601 and is positioned between the fixed clamping block 501 and the sliding clamping block 601. At this time, under the support of the sliding clamping block 601, the sheet metal is located above the lower mold and is in a suspended state.
[0053] When the hydraulic stamping module 2 operates, as the upper die approaches the lower die, the fixed clamping block 501 gradually moves closer to the sliding clamping block 601 to clamp the sheet metal. After clamping, the sheet metal and the sliding clamping block 601 move synchronously towards the lower die until the sheet metal contacts the lower die. Then, the upper and lower dies cooperate to complete the punching operation on the sheet metal.
[0054] Next, the hydraulic stamping module 2 will move the upper mold away from the lower mold. At this time, the fixed clamping block 501 and the sliding clamping block 601 will separate the sheet metal from the lower mold to restore the suspended state and release the clamping state of the sheet metal. Then the suspended part will move, thereby rotating the lever 19 to push the sheet metal towards the unloading ramp 101 to complete the unloading.
[0055] By using the suspended component to hold the sheet metal, the position of the sheet metal can be prevented from shifting during the punching process, which would affect the processing quality. Furthermore, the suspended component can separate the processed sheet metal from the lower die, preventing the punched part of the sheet metal from sticking to the lower die, thereby reducing the material discharge resistance. The ejector component pushes the sheet metal to complete the ejection process, which is relatively gentle and can prevent the sheet metal from violently colliding with the machine casing 1 or the die, thereby protecting the sheet metal and the die and improving the service life of the die.
[0056] As a further embodiment of this utility model, the suspended component further includes a fixed post 4 fixedly installed on the base plate 3; a first sliding rod 5 and a second sliding rod 6 are slidably installed inside the fixed post 4; the first sliding rod 5 is fixedly connected to the fixed clamping block 501; the second sliding rod 6 is fixedly connected to the sliding clamping block 601, and the sliding clamping block 601 is slidably engaged with the fixed clamping block 501; a baffle 502 is fixedly installed on the first sliding rod 5; a first spring 8 is wrapped around the first sliding rod 5; a second spring 9 is provided inside the fixed post 4; the two ends of the first spring 8 respectively abut against the baffle 502 and the base plate 3; the two ends of the second spring 9 respectively abut against the second sliding rod 6 and the base plate 3; multiple sets of first sliding rods 5 are fixedly connected by a connecting plate 7.
[0057] In this embodiment, after the sheet metal is placed on the sliding clamping block 601, the hydraulic stamping module 2 is activated, thereby driving the upper mold to move closer to the lower mold. During this process, the fixed clamping block 501 will move closer to the sliding clamping block 601, thereby contacting the sheet metal. At the same time, the first spring 8 will be compressed under the squeezing action of the baffle 502.
[0058] After the fixed clamping block 501 comes into contact with the plate, it will drive the sliding clamping block 601 to move synchronously through the plate. At this time, the plate is clamped. During the movement of the plate, it will drive the first slide bar 5 and the second slide bar 6 to move synchronously (under the action of the connecting plate 7, multiple sets of fixed clamping blocks 501 will move synchronously), thereby compressing the first spring 8 and the second spring 9 until the plate and the lower mold come into contact.
[0059] After the sheet metal is processed, the upper mold will move away from the sheet metal and the lower mold under the action of the hydraulic stamping module 2. During this process, the fixed clamping block 501 and the sliding clamping block 601 will move the sheet metal away from the lower mold under the elastic force of the first spring 8 and the second spring 9 to restore the suspended state. During this process, the first slide rod 5 and the second slide rod 6 will slide in the fixed column 4.
[0060] Furthermore, after the sliding clamp 601 moves to the initial position, the fixed clamp 501 will continue to move under the elastic force of the first spring 8, thereby separating the fixed clamp 501 from the plate and releasing the plate.
[0061] By using the suspended component to clamp the sheet metal, the position of the sheet metal can be prevented from shifting during the punching process, which would affect the processing quality. Furthermore, by using the suspended component to separate the processed sheet metal from the lower die, the punching position of the sheet metal can be prevented from sticking to the lower die, thereby reducing the material discharge resistance.
[0062] As a further embodiment of this utility model, a fixing sleeve 11 is fixedly installed on the top plate 201; a telescopic column 13 is slidably installed inside the fixing sleeve 11; a trigger plate 14 that cooperates with a set of fixing clamps 501 is fixedly installed at the end of the telescopic column 13; a third spring 12 is provided inside the fixing sleeve 11; the two ends of the third spring 12 abut against the telescopic column 13 and the top plate 201 respectively.
[0063] In this embodiment, as the top plate 201 approaches the bottom plate 3, the telescopic column 13 will move synchronously via the third spring 12, thereby moving the trigger plate 14. During the movement of the trigger plate 14, it will contact a set of fixed clamping blocks 501, and after contact, it will move the fixed clamping blocks 501 synchronously. The connecting plate 7 will also move multiple sets of fixed clamping blocks 501 synchronously to clamp the plate and move the plate closer to the mold.
[0064] After the sheet metal comes into contact with the lower mold, the sliding clamping block 601 and the fixed clamping block 501 are locked in position. At this time, the upper mold and the lower mold do not cooperate with each other.
[0065] Afterwards, the top plate 201 continues to move to drive the upper mold and the lower mold to cooperate, thereby completing the processing of the plate; during this process, the telescopic column 13 will slide inward in the fixed sleeve 11, thereby compressing the third spring 12.
[0066] As the top plate 201 moves away from the bottom plate 3, the telescopic column 13 will remain in contact with the fixed clamp 501 under the elastic force of the third spring 12. The fixed sleeve 11 will move, causing the telescopic column 13 to slide outward within the fixed sleeve 11 to release the elastic force of the third spring 12.
[0067] When the telescopic column 13 moves to the end of its stroke, the top plate 201 will drive the telescopic column 13 to move synchronously. Under the elastic force of the first spring 8 and the second spring 9, the fixed clamping block 501 and the sliding clamping block 601 will drive the plate away from the lower mold, and release the plate after the sliding clamping block 601 returns to its original position.
[0068] By using the suspended component to clamp the sheet metal, the position of the sheet metal can be prevented from shifting during the punching process, which would affect the processing quality. Furthermore, by using the suspended component to separate the processed sheet metal from the lower die, the punching position of the sheet metal can be prevented from sticking to the lower die, thereby reducing the material discharge resistance.
[0069] As a further embodiment of this utility model, the ejector also includes a rotating rod 16 rotatably mounted on the base plate 3; a connecting rod 18 fixedly mounted on the rotating rod 16 and fixedly connected to the lever 19.
[0070] In this embodiment, when the rotating rod 16 rotates, it will drive the connecting rod 18 to rotate, thereby driving the lever 19 to rotate synchronously.
[0071] Initially, the lever 19 and the unloading ramp 101 are on the same side. During the processing of the sheet metal, the suspended part will drive the rotating rod 16 to rotate 180°, thereby driving the lever 19 to rotate 180°, so that the lever 19 moves to the side away from the unloading ramp 101.
[0072] After processing, the suspended component will cause the plate to return to a suspended state. During this process, the suspended component will cause the rotating rod 16 to continue to rotate 180°, thereby causing the lever 19 to rotate 180°. During this process, the lever 19 will contact the plate and push the plate towards the unloading ramp 101 after contact. When the plate is no longer in contact with the suspended component, the plate will fall into the unloading ramp 101 and be discharged outward.
[0073] The ejector component pushes the sheet metal to complete the ejection process, which is relatively gentle and can avoid violent collisions between the sheet metal and the chassis 1 or the mold, thereby protecting the sheet metal and the mold and improving the service life of the mold.
[0074] As a further embodiment of this utility model, a fixing rod 10 is fixedly installed on the connecting plate 7; a set of mating grooves is provided on the fixing rod 10; a first gear 15 is rotatably installed on the base plate 3 and sleeved on the fixing rod 10; a protruding post 1501 that slides and engages with the set of mating grooves is fixedly installed inside the first gear 15; a second gear 17 that meshes with the first gear 15 is fixedly installed on the rotating rod 16.
[0075] As a further embodiment of this utility model, the mating groove assembly includes a first straight groove 1001, a first inclined groove 1002, a second straight groove 1003, and a second inclined groove 1004; wherein, one end of the first straight groove 1001 is connected to one end of the first inclined groove 1002, the other end of the first inclined groove 1002 is connected to one end of the second straight groove 1003, the other end of the second straight groove 1003 is connected to one end of the second inclined groove 1004, and the other end of the second inclined groove 1004 is connected to the other end of the first straight groove 1001.
[0076] In this embodiment, the processing procedure is as follows: the first slide bar 5 moves away from the top plate 201 under the drive of the trigger plate 14, thereby causing the protruding column 1501 to slide in the first straight groove 1001 first, at which time the first gear 15 does not rotate; then the protruding column 1501 slides in the first inclined groove 1002, and under the squeezing action of the protruding column 1501 and the first inclined groove 1002, the first gear 15 rotates, thereby driving the second gear 17 to rotate, so as to drive the rotating rod 16 to rotate, so that the lever 19 rotates to the side away from the unloading ramp 101.
[0077] Reset process: The first slide bar 5 will move towards the top plate 201 under the elastic force of the first spring 8, thereby causing the protruding column 1501 to slide in the second straight groove 1003. At this time, the first gear 15 does not rotate. Then the protruding column 1501 will slide in the second inclined groove 1004. Under the squeezing action of the protruding column 1501 and the second inclined groove 1004, the first gear 15 will rotate, thereby driving the second gear 17 to rotate, so as to drive the rotating rod 16 to rotate, so as to rotate the lever 19 to the side close to the unloading ramp 101, so as to push the plate and the suspended part to separate, thereby completing the unloading.
[0078] The ejector component pushes the sheet metal to complete the ejection process, which is relatively gentle and can avoid violent collisions between the sheet metal and the chassis 1 or the mold, thereby protecting the sheet metal and the mold and improving the service life of the mold.
[0079] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
