Description

Technical Field

[0001] This invention relates to the field of punch press technology, specifically to a punch press with an automatic waste chip cleaning structure. Background Technology

[0002] Punch presses are commonly used equipment in machining, mainly used to stamp metal sheets to directly obtain products formed by die pressing. Servo punch presses use servo motors as the direct power source, and convert the driving force generated by the motor into the linear motion of the slide block through screws, crank connecting rods and toggle rods, thereby stamping the workpiece.

[0003] Currently, when existing punch presses process workpieces, iron filings may fall off during the stamping deformation process. These filings left on the stamping die can affect subsequent stamping, thereby damaging the workpiece and affecting the quality of the stamped product. These filings usually need to be removed manually, which requires the operator to stop the punch press and ensure safety before cleaning. This method requires continuous starting and stopping of the punch press, which affects the working efficiency of the punch press. In view of this, we propose a punch press with an automatic filings cleaning structure. Summary of the Invention

[0004] The main objective of this invention is to provide a punch press with an automatic waste chip cleaning structure, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a punch press with an automatic waste cleaning structure, comprising a punch press body, a lower die fixedly connected to the operating table of the punch press body, a punching mechanism disposed above the lower die, a collection box placed at the bottom of the punch press body, a cleaning mechanism and an auxiliary cleaning component disposed on the side of the lower die, an auxiliary sliding component disposed below the cleaning mechanism, and a pulling component disposed above the cleaning mechanism. The cleaning mechanism includes:

[0006] Elastic telescopic rod one, which is fixedly connected to the inner wall of the punch press body, and a fixed rod is fixedly connected to the telescopic end of the elastic telescopic rod one;

[0007] A connecting rod is hinged to the telescopic end of the first elastic telescopic rod. A cleaning brush is fixedly connected to the end of the connecting rod away from the first elastic telescopic rod. A second elastic telescopic rod is fixedly connected to the outer wall of the connecting rod. By using the cleaning brush, the cleaning brush can automatically clean the lower mold when it moves downward.

[0008] A sliding sleeve, wherein the fixed rod passes through the sliding sleeve and is slidably connected to the sliding sleeve, and a connecting rod is fixedly connected to the lower end of the sliding sleeve, and the end of the connecting rod is hinged to a hinge rod one and a hinge rod two;

[0009] And a diagonal rod one, wherein the diagonal rod one is hinged to a hinge rod one, and the hinge rod two is hinged to a diagonal rod two.

[0010] Preferably, the center of the first and second inclined rods is penetrated by a positioning shaft, and both the first and second inclined rods are rotatably connected to the positioning shaft. By rotating the first and second inclined rods, the first and second hinged rods can be moved. Under the action of the fixed rod and the sliding sleeve, the connecting rod can be moved, and the telescopic end of the first elastic telescopic rod can be extended, so that the cleaning brush can clean the lower mold.

[0011] Preferably, the auxiliary cleaning component includes a fixed plate. A wedge block is fixedly connected to the side of the fixed plate near the elastic telescopic rod 2, and a fixed chamber is fixedly connected to the side of the fixed plate away from the elastic telescopic rod 2. By using the wedge block, after the cleaning brush has cleaned the lower mold, the telescopic end of the elastic telescopic rod 2 slides on the wedge block, allowing the connecting rod to tilt upwards and rotate. After the elastic telescopic rod 2 passes the wedge block, the connecting rod falls back down, causing the cleaning brush to vibrate and shake off the iron filings on the cleaning brush, which facilitates subsequent improvement of the cleaning effect of the cleaning brush. At the same time, when the cleaning brush resets, the telescopic end of the elastic telescopic rod 2 is compressed by the wedge block, and the connecting rod can reset normally without tilting upwards, ensuring the stability of the cleaning brush reset and preventing the iron filings left on the cleaning brush from falling onto the lower mold during the cleaning brush reset process.

[0012] Preferably, a sliding plate is slidably connected to the inner wall of the fixed chamber, a pressure rod is fixedly connected to the lower side of the sliding plate, and an elastic airbag is embedded inside the fixed chamber.

[0013] Preferably, a one-way air inlet is provided on the outer wall of the fixed chamber, and the one-way air inlet is connected to the elastic airbag. The elastic airbag is connected to a hose, and a nozzle is connected to the end of the hose away from the elastic airbag. The nozzle is fixedly connected to the outer wall of the cleaning brush. The gas from the elastic airbag flows into the nozzle and is sprayed out by the nozzle, which can improve the cleaning effect on the iron filings on the lower mold.

[0014] Preferably, the auxiliary sliding assembly includes a vertical rod, a fixing ring is fixedly connected to the outer wall of the vertical rod, the fixing ring is elastically connected to the operating table of the punch press body through a return spring, the vertical rod passes through the outer wall of the punch press body and is slidably connected to the outer wall of the operating table of the punch press body, and helical teeth are fixedly connected to the outer wall of the vertical rod.

[0015] Preferably, a support member is fixedly connected to the lower surface of the punch press body, and a swing rod is hinged to the support member. A striking ball is fixedly connected to the end of the swing rod away from the helical teeth. The swing rod rotates, causing the striking ball to strike and vibrate the bottom surface of the notch, thereby causing the iron filings attached to the notch to slide onto the collection box more quickly, making it easier for the staff to collect and process the iron filings later.

[0016] Preferably, the pulling assembly includes a crossbar that passes through diagonal bar one and diagonal bar two, and diagonal bar one and diagonal bar two are fixedly connected to the crossbar. A rotating collar is sleeved on the outer wall of the crossbar, and a U-shaped rod is connected to the outer wall of the rotating collar.

[0017] Preferably, a fixing block is fixedly connected to the end of the U-shaped rod away from the rotating collar, the U-shaped rod passes through the positioning sleeve and is slidably connected to the positioning sleeve, and a positioning rod is fixedly connected to the outer wall of the positioning sleeve.

[0018] Preferably, a notch is provided on the outer wall of the operating table of the punch press body, and a limit block is fixedly connected to the outer surface of the punching mechanism.

[0019] This invention provides a punch press with an automatic waste chip cleaning structure. It has the following beneficial effects:

[0020] (1) The punch press with automatic waste cleaning structure uses a cleaning mechanism and a pulling component. During the upward movement of the punching mechanism, the limiting block gradually rises and contacts the fixed block, lifting the fixed block upward. Under the pulling action of the U-shaped rod, the first and second inclined rods rotate, driving the first and second hinge rods to move. Under the action of the fixed rod and the sliding sleeve, the connecting rod can move and drive the extension end of the first elastic telescopic rod to extend, so that the cleaning brush can automatically clean the lower die. During the downward movement of the punching mechanism, the first elastic telescopic rod drives the cleaning brush to reset, which will not affect the punching of the workpiece. There is no need for the operator to stop the punch press, thus ensuring the working efficiency of the punch press.

[0021] (2) The punch press with automatic waste cleaning structure uses a cleaning mechanism and auxiliary cleaning components to make the cleaning brush move to the notch after cleaning the lower die. The telescopic end of the elastic telescopic rod 2 slides on the inclined block, which allows the connecting rod to tilt upward and rotate. After the elastic telescopic rod 2 passes the inclined block, the connecting rod falls back down, realizing the shaking of the cleaning brush and shaking off the iron filings on the cleaning brush. This facilitates the subsequent improvement of the cleaning effect of the cleaning brush. At the same time, when the cleaning brush is reset, the telescopic end of the elastic telescopic rod 2 is compressed by the inclined block, and the connecting rod can be reset normally without tilting upward. This ensures the stability of the cleaning brush reset and prevents the iron filings left on the cleaning brush from falling onto the lower die during the cleaning brush reset process.

[0022] (3) The punch press with automatic waste cleaning structure uses auxiliary cleaning components so that when the cleaning brush cleans the lower die, the inclined rod will squeeze the pressure rod during the rotation, causing the pressure rod to rise and drive the sliding plate to squeeze the elastic air bag. The gas in the elastic air bag moves through the hose to the nozzle and is sprayed out from the nozzle, blowing away the iron filings on the lower die and improving the cleaning effect of the iron filings on the lower die.

[0023] (4) The punch press with automatic waste cleaning structure uses the auxiliary sliding component to make the second inclined bar squeeze the vertical bar down during the rotation and reset process. Then, under the action of the inclined teeth, the swing bar swings and drives the striking ball to strike and vibrate the bottom surface of the notch. This makes the iron filings attached to the notch slide down to the collection box more quickly, which is convenient for the staff to collect and process the iron filings in a concentrated manner.

[0036] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-9This invention proposes a punch press with an automatic waste chip cleaning structure, including a punch press body 1. A notch 101 is provided on the outer wall of the operating table of the punch press body 1, allowing the scrap metal to slide off during subsequent cleaning. A lower die 2 is fixedly connected to the operating table of the punch press body 1. A stamping mechanism 3 is arranged above the lower die 2. The stamping mechanism 3 is a conventional stamping structure of the punch press body 1, using a servo motor as the direct power source. Through a screw, crank connecting rod, and toggle lever, the driving force generated by the motor is converted into the linear motion of a slider, thereby stamping the workpiece. A limit block 31 is fixedly connected to the outer surface of the stamping mechanism 3. A collection box 4 is placed at the bottom of the punch press body 1, allowing for the collection of scrap metal. The lower die 2... A cleaning mechanism 5 and an auxiliary cleaning component 6 are provided on the side for cleaning the lower die 2. The cleaning mechanism 5 and the auxiliary cleaning component 6 can automatically clean the iron filings on the lower die 2. The cleaning mechanism 5 includes an elastic telescopic rod 51, which is fixedly connected to the inner wall of the punch press body 1. A fixing rod 52 is fixedly connected to the telescopic end of the elastic telescopic rod 51. A connecting rod 53 is hinged to the telescopic end of the elastic telescopic rod 51. A cleaning brush 55 is fixedly connected to the end of the connecting rod 53 away from the elastic telescopic rod 51. An elastic telescopic rod 54 is fixedly connected to the outer wall of the connecting rod 53. An auxiliary sliding component 7 is provided below the cleaning mechanism 5. The auxiliary sliding component 7 can accelerate the collection of iron filings into the collection box 4. A pulling component 8 is provided above the cleaning mechanism 5.

[0039] In an embodiment of the present invention, the fixing rod 52 passes through the sliding sleeve 56 and is slidably connected to the sliding sleeve 56. The sliding sleeve 56 is used to limit the movement of the fixing rod 52. A connecting rod 57 is fixedly connected to the lower end of the sliding sleeve 56. A first hinge rod 58 and a second hinge rod 59 are hinged to the end of the connecting rod 57. The first hinge rod 58 is hinged to a first inclined rod 511, and the second hinge rod 59 is hinged to a second inclined rod 510. A positioning shaft passes through the center of the first inclined rod 511 and the second inclined rod 510, and both the first inclined rod 511 and the second inclined rod 510 are connected to the positioning shaft. The rotating connection and pulling assembly 8 includes a horizontal bar 81, which passes through inclined bar 1 511 and inclined bar 2 510. Both inclined bar 1 511 and inclined bar 2 510 are fixedly connected to the horizontal bar 81. By rotating inclined bar 1 511 and inclined bar 2 510, hinge rod 1 58 and hinge rod 2 59 can be moved. Under the action of fixed rod 52 and sliding sleeve 56, connecting rod 57 can be moved, and the telescopic end of elastic telescopic rod 1 51 can be extended, so that cleaning brush 55 can clean the lower mold 2. The outer wall of the horizontal bar 81 is fitted with... A rotating collar 82 is connected to the outer wall of the rotating collar 82, and a U-shaped rod 83 is connected to the outer wall of the rotating collar 82. A fixing block 86 is fixedly connected to the end of the U-shaped rod 83 away from the rotating collar 82. The U-shaped rod 83 passes through the positioning sleeve 84 and is slidably connected to the positioning sleeve 84. A positioning rod 85 is fixedly connected to the outer wall of the positioning sleeve 84. During the upward movement of the stamping mechanism 3, the limiting block 31 gradually rises and contacts the fixing block 86, lifting the fixing block 86 upward. Under the limiting action of the positioning sleeve 84 on the U-shaped rod 83, the U-shaped rod 83 pulls the crossbar 81 upward, causing... The rotation of inclined rod 511 and inclined rod 510 causes hinge rod 58 and hinge rod 59 to move. Under the action of fixed rod 52 and sliding sleeve 56, connecting rod 57 can move and extend the telescopic end of elastic telescopic rod 51, so that cleaning brush 55 can automatically clean the lower die 2. At the same time, during the downward movement of the stamping mechanism 3, elastic telescopic rod 51 drives cleaning brush 55 to reset, which will not affect the stamping of the workpiece. It does not require the operator to stop the stamping machine, thus ensuring the working efficiency of the stamping machine.

[0040] Furthermore, to improve the cleaning effect on the lower mold 2, the auxiliary cleaning component 6 includes a fixing plate 61. A wedge block 62 is fixedly connected to the side of the fixing plate 61 near the elastic telescopic rod 54. After the cleaning brush 55 cleans the lower mold 2, as it moves to the recess 101, the telescopic end of the elastic telescopic rod 54 slides on the wedge block 62, allowing the connecting rod 53 to rotate upwards. After the telescopic end of the elastic telescopic rod 54 passes the wedge block 62, the connecting rod 53 falls back down, causing the cleaning brush 55 to vibrate and shake off the iron filings on the cleaning brush 55. This facilitates improving the cleaning effect of the cleaning brush 55 in the future. At the same time, when the cleaning brush 55 resets, the telescopic end of the elastic telescopic rod 54 is compressed by the wedge block 62, allowing the connecting rod 53 to reset normally without tilting upwards. This ensures the stability of the cleaning brush 55's reset and prevents the iron filings left on the cleaning brush 55 from falling onto the lower mold 2 during the reset process.

[0041] Furthermore, to further improve the cleaning effect of the lower mold 2, specifically, a fixed chamber 63 is fixedly connected to the side of the fixed plate 61 away from the elastic telescopic rod 54. A sliding plate 64 is slidably connected to the inner wall of the fixed chamber 63, and a pressure rod 65 is fixedly connected to the lower side of the sliding plate 64. An elastic airbag 66 is embedded inside the fixed chamber 63, and a one-way air inlet 67 is provided on the outer wall of the fixed chamber 63. The one-way air inlet 67 is connected to the elastic airbag 66. Through the use of the one-way air inlet 67, the elastic airbag 66 can draw in gas during the resetting process, and during the process of the elastic airbag 66 expelling gas, the one-way air inlet... 67 will not overflow gas. The elastic airbag 66 is connected to the hose 68. The end of the hose 68 away from the elastic airbag 66 is connected to the nozzle 69. The nozzle 69 is fixedly connected to the outer wall of the cleaning brush 55. During the upward movement of the stamping mechanism 3, the first inclined rod 511 and the second inclined rod 510 rotate. During the rotation of the first inclined rod 511, it will squeeze the pressure rod 65, causing the pressure rod 65 to rise. This will drive the sliding plate 64 to squeeze the elastic airbag 66, causing the gas in the elastic airbag 66 to move through the hose 68 to the nozzle 69 and be sprayed out from the nozzle 69. This will blow away the iron filings on the lower die 2, thereby further improving the cleaning effect on the iron filings on the lower die 2.

[0042] It should be noted that, in order to accelerate the speed at which iron filings slide off the notch 101, specifically, the auxiliary sliding component 7 includes a vertical rod 71, with a fixing ring 73 fixedly connected to the outer wall of the vertical rod 71. The fixing ring 73 is elastically connected to the operating table of the punch press body 1 via a return spring. The use of the return spring facilitates the return of the vertical rod 71, allowing the vertical rod 71 to fit against the inclined rod 510. The vertical rod 71 penetrates the outer wall of the punch press body 1 and is slidably connected to the outer wall of the operating table of the punch press body 1. A helical tooth 72 is fixedly connected to the outer wall of the vertical rod 71. A support member 74 is fixedly connected to the lower surface of 1. A swing rod 75 is hinged to the support member 74. A striking ball 76 is fixedly connected to the end of the swing rod 75 away from the helical tooth 72. During the downward movement of the stamping mechanism 3, the helical rod 510 can squeeze the vertical rod 71 to descend during the rotation and reset process. Then, under the action of the helical tooth 72, the swing rod 75 swings, which drives the striking ball 76 to strike and vibrate the bottom surface of the notch 101. This causes the iron filings attached to the notch 101 to slide down onto the collection box 4 more quickly, making it easier for the staff to collect and process the iron filings later.

[0043] In use, the stamping mechanism 3 can stamp the workpiece on the lower die 2. During this process, when the stamping mechanism 3 moves upward, the limiting block 31 gradually rises and contacts the fixed block 86, lifting the fixed block 86 upward. Under the limiting action of the positioning sleeve 84 on the U-shaped rod 83, the U-shaped rod 83 pulls the horizontal bar 81 upward, causing the inclined rod 1 511 and inclined rod 2 510 to rotate, driving the hinge rod 1 58 and hinge rod 2 59 to move. Under the action of the fixed rod 52 and the sliding sleeve 56, the connecting rod 57 can move, and the extension end of the elastic telescopic rod 1 51 can be extended, so that the cleaning brush 55 can automatically clean the lower die 2. During the downward movement of the stamping mechanism 3, the elastic telescopic rod 1 51 drives the cleaning brush 55 to reset, which will not affect the stamping of the workpiece.

[0044] Meanwhile, after cleaning the lower mold 2, as the cleaning brush 55 moves to the recess 101, the telescopic end of the elastic telescopic rod 54 slides on the inclined block 62, allowing the connecting rod 53 to rotate upwards. After the telescopic end of the elastic telescopic rod 54 passes the inclined block 62, the connecting rod 53 falls back down, causing the cleaning brush 55 to vibrate and shake off the iron filings on the cleaning brush 55, which facilitates improving the cleaning effect of the cleaning brush 55 in the future. At the same time, when the cleaning brush 55 is reset, the telescopic end of the elastic telescopic rod 54 is compressed by the inclined block 62, and the connecting rod 53 can be reset normally without tilting upwards, preventing the iron filings left on the cleaning brush 55 from falling onto the lower mold 2 during the reset process.

[0045] Simultaneously, during the upward movement of the stamping mechanism 3, the first inclined rod 511 and the second inclined rod 510 rotate. During the rotation of the first inclined rod 511, it will squeeze the pressure rod 65, causing the pressure rod 65 to rise. This will drive the sliding plate 64 to squeeze the elastic air bag 66, causing the gas in the elastic air bag 66 to move through the hose 68 to the nozzle 69 and be sprayed out from the nozzle 69, blowing away the iron filings on the lower die 2. During the downward movement of the stamping mechanism 3, the second inclined rod 510 can squeeze the vertical rod 71 to descend during the rotation and reset process. Then, under the action of the helical teeth 72, the swing rod 75 swings, causing the striking ball 76 to strike and vibrate the bottom surface of the notch 101, thereby accelerating the sliding of the iron filings attached to the notch 101 onto the collection box 4.
