Description

Technical Field

[0001] The invention belongs to the field of high-speed presses, and in particular relates to a press with a self-cleaning device. Background Art

[0002] A high-speed press is a highly efficient machine suitable for high-volume, high-precision stamping production. Its core features include high speed, high precision, a high degree of automation, and specialized design. Motor-driven presses, with their advantages of high precision, energy saving, and flexibility, have performed outstandingly in the fields of precision manufacturing and green production. Examples include the press drive device for a press and a press having a press drive device disclosed in CN201580056723.6. Motor-driven presses have advantages such as high precision and stability, energy saving and high efficiency, flexible production, intelligence, and safety. Due to the continuous operation of high-speed presses, some debris and burrs will accumulate on the lower die and the lower die mounting table. In traditional cleaning methods, these debris and fallen burrs are basically cleaned by staff at the stamping station using handheld cleaning brushes. With the requirements of automated workshops, many operations are gradually being replaced by motorized structures, including cleaning operations on the press surface.

[0003] The existing patent CN202222691143.4 discloses an air blowing cleaning device for a press platform, which adopts an air blowing method for cleaning. The press with a cleaning function disclosed in CN202022105331.5 adopts a flat push method. The cleaning operation of these devices depends on the flatness of the working surface of the press. However, for a high-speed press that needs to install a lower mold, it is impossible to clean the debris and burrs on the surface of the lower mold after the lower mold is installed, and even the installation base surface of the lower mold cannot be cleaned maneuverably. Moreover, for a complete For equipment that relies entirely on air blowing to perform cleaning operations, since debris and fallen burrs are different from dust and have a certain mass, if the air blowing power is too low, the cleaning function cannot be achieved, and if the air blowing power is too high, the debris and fallen burrs will be splashed again, affecting the actual cleaning effect of the workstation and the safety of operation; secondly, some cleaning devices occupy the stamping plane of the press. Although it does not affect the stamping of the workpiece, the debris and fallen burrs will fall directly onto the surface of the cleaning device, and it mostly relies on manual cleaning, so its cleaning performance needs to be improved.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Examples, such as Figures 1 to 12 As shown, the present invention provides a press with a self-cleaning device, including a machine body 1, on which a stamping drive box, a lifting slider, an upper mold, a lower mold 11, a support platform 12 for mounting the lower mold 11, and a buffer device for providing a safety mechanism are provided, wherein the upper mold and the lower mold 11 are selected according to the actual processing needs of the workpiece, and are respectively mounted on the lifting slider and the support platform 12. These structures are existing mature technologies and will not be described in detail in this embodiment. In order to ensure the quality of the working surface of the press, the present invention provides a motorized cleaning device to achieve automatic cleaning, and the cleaning device can be concealedly installed near the stamping working plane to ensure the safety of the stamping work.

[0035] Specifically, the support platform 12 provided by the present invention is provided with a profiling drive box 2 on both sides, the profiling drive box 2 is provided with a profiling track hole 21, and the interior of the profiling drive box 2 is provided with a driving mechanism 22. A roller-type cleaning component 3 connected to the driving mechanism 22 is provided between the two profiling drive boxes 2. The roller-type cleaning component 3 is driven by the driving mechanism 22 and moves along the side and upper surface of the support platform 12 and the lower mold 11 for profiling. The roller-type cleaning component is used to absorb debris and fallen burrs attached to the support platform 12 and the lower mold 11. Positioning grooves 13 are provided on both sides of the support platform 12, and support rails 4 for concealedly accommodating the roller-type cleaning component are provided in the positioning grooves 13. A collection box 5 for collecting debris and fallen burrs released by the roller-type cleaning component is provided below the support platform 12.

[0036] In this device, two contour drive boxes 2 are located on the left and right sides of the support platform 12. Because the cross-section of the lower mold 11 is necessarily smaller than that of the support platform 12, the contour drive boxes 2 do not affect the stamping and parting of the upper and lower molds 11. Furthermore, when not performing cleaning operations, the roller cleaning component 3 is located within the support rails 4, which are concealedly installed on the front and rear sides of the support platform 12. Therefore, the roller cleaning component 3 does not affect the stamping and parting of the upper and lower molds 11, and the debris and burrs generated during the stamping process will basically not fall on the roller cleaning component 3. The working principle of the contour drive box 2 and the roller-type cleaning component 3 is as follows: the driving mechanism 22 in the contour drive box 2 provides traction power for the roller-type cleaning component 3, and the roller-type cleaning component 3 moves out of the support rail 4 and can move in an orderly manner along the surface of the support platform 12 and the lower mold 11. Its adsorption working surface is always in a state facing the surface of the support platform 12 and the lower mold 11 due to its own weight. During the movement of the roller-type cleaning component 3, the debris and fallen burrs are taken away by adsorption. Finally, at the terminal position near the rear side of the body 1, the adsorbed debris and burrs are released into the collection box 5, thereby achieving the purpose of cleaning the support platform 12 and the lower mold 11, rather than just cleaning the support platform 12. In this way, the device can contour move along the mold surface and the support platform 12 to complete the cleaning, with high cleaning efficiency, and does not occupy the working plane of the upper mold and the lower mold 11. It has high space utilization and high safety, and is suitable for large-scale promotion.

[0037] To improve the cleaning efficiency of the roller-type cleaning component 3, the contoured track hole 21 provided by the present invention includes two L-shaped segments 211 and a convex segment 212 connecting the two L-shaped segments 211. One end of the L-shaped segment 211 extends toward the support track 4, and the other end of the L-shaped segment 211 connects to the convex segment 212 upward. The bottom, side, and top segments of the convex segment 212 are respectively parallel to the top surface of the support platform 12, the side surfaces of the lower mold 11, and the top surface of the lower mold 11. The L-shaped segment 211 provides a movement path for the roller-type cleaning component 3 to enter and exit the support track 4, allowing it to be effectively concealed under the cover of the support platform 12 when not in operation. The convex segment 212 provides a movement path for the roller-type cleaning component 3 along the top surface of the support platform 12, the side surfaces of the lower mold 11, and the top surface of the lower mold 11, especially along the top surface of the support platform 12 and the top surface of the lower mold 11. This ensures the effectiveness of the cleaning path of the roller-type cleaning component 3, thereby facilitating the efficiency of the cleaning work.

[0038] like Figures 8 to 10 As shown, the roller-type cleaning component 3 includes an outer shaft 31, with shaft heads 311 provided at both ends of the outer shaft 31. A traction head 32 is provided at the end of the shaft head 311. The traction head 32 is in transmission connection with the drive mechanism 22. The side of the traction head 32 can be provided with a limiting shoulder and can be rolled with the contoured track hole 21. The side of the outer shaft 31 is provided with multiple adsorption components 33. Among them, the traction head 32 and the shaft head 311 are in a smoothly nested relationship, and the shaft head 311 can maintain the ability to flexibly rotate within the nesting surface of the traction head 32. Due to the provision of the adsorption components 33, the center of gravity of the roller-type cleaning component 3 is basically close to the adsorption components 33. Therefore, during the continuous movement of the roller-type cleaning component 3, the adsorption components 33 can maintain a downward posture to the greatest extent possible. Therefore, when the adsorption components 33 pass through the upper surface of the support platform 12 and the top surface of the lower mold 11, their working surface can always face the object to be cleaned.

[0039] In order to improve the storage effect of the support rail 4 on the roller-type cleaning component 3, the support rail 4 provided by the present invention includes a U-shaped groove with an opening toward the front and rear sides of the body 1, and the upper and lower groove surfaces of the U-shaped groove form a protective surface of the roller-type cleaning component 3. A horizontal T-shaped block is provided in the U-shaped groove, and the end of the T-shaped block is provided with an arc groove matching the outer shaft 31. In this way, the outer shaft 31 can maintain its side contact and the upper and lower surfaces suspended after entering the support rail 4, which plays a limiting role and will not hit the adsorption component 33.

[0040] Taking into account the limited working area of ​​the roller-type cleaning component 3, in order to ensure the cleaning capacity of the cleaning process, the present invention allows the adsorption assembly 33 to move axially back and forth. Specifically, the multiple adsorption assemblies 33 provided by the present invention are divided into two rows and are symmetrically distributed near the axial plane of the outer shaft 31. The adsorption assemblies 33 in adjacent rows are axially staggered. The side of the outer shaft 31 is provided with multiple guide holes 312 that correspond one-to-one with the adsorption assemblies 33 and allow the adsorption assemblies 33 to move axially. The interior of the outer shaft 31 is provided with a cylindrical cam inner shaft 34. The side of the cylindrical cam inner shaft 34 is provided with a cylindrical cam track 35 that movably cooperates with the adsorption assembly 33. The end of the cylindrical cam inner shaft 34 is provided with a stepping motor. Among them, the stepper motor is used to provide rotational power to the inner shaft 34 of the cylindrical cam. The inner shaft 34 of the cylindrical cam adopts a stepping rotation method to convert its rotational motion into a reciprocating translational motion of the adsorption component 33, and the staggered distribution of the two rows of adsorption components 33 can form a relatively continuous cleaning section. Therefore, when the roller-type cleaning component 3 maintains a reasonable moving speed through the upper surface of the support platform 12 and the top surface of the lower mold 11, the cleaning work of the entire surface to be cleaned can be completed.

[0041] The suction cup 331 is provided with an adsorption groove 332, and an electromagnet 333 and a negative pressure hole 334 symmetrically distributed about the electromagnet 333 are provided in the adsorption groove 332. The negative pressure hole 334 adopts a narrow flat hole design. The back of the adsorption cup 331 is provided with a pair of guide posts 335 connected to the negative pressure hole 334. The guide posts 335 cooperate with the cylindrical cam track 35. The cylindrical cam inner shaft 34 is a hollow structure and is internally provided with a negative pressure branch pipe 336 connected to the guide posts 335. The negative pressure branch pipe 336 is connected to the negative pressure main pipe arranged in the profiling drive box 2. The negative pressure main pipe has sufficient length margin in the profiling drive box to meet the roller-type cleaning component and always maintain a reliable connection relationship with it. One end of the negative pressure main pipe can be directly connected to the traction head to connect with the negative pressure branch pipe 336. The pressure supply end of the negative pressure main pipe is provided with a negative pressure pump, which can be arranged inside the machine body. In this case, the adsorption component 33 has another advantage when it is driven by the inner shaft 34 of the cylindrical cam to move axially back and forth. For example, when there are a lot of debris and burrs in a local position, the adsorption component 33 can push the debris and burrs protruding from the adsorption end level of the adsorption component 33 to other positions of the adsorption groove 332 by reciprocating movement, thereby filling the vacant space in the adsorption groove 332, avoiding excessive accumulation of debris and burrs in a local position of the adsorption groove 332 and affecting subsequent cleaning work, thereby ensuring that the roller-type cleaning component 3 can complete the cleaning operation to the maximum extent in one stroke, reducing the number of work strokes that actually need to be completed.

[0042] Furthermore, regarding the adsorption component 33, it provides at least two adsorption methods to adsorb debris and burrs. Specifically, the electromagnet 333 includes an iron core and a coil. One end of the adsorption seat 331 is provided with a wire interface that can connect the coil to a power supply, and the adsorption surface of the iron core faces the outside of the adsorption groove 332. In this way, if the workpiece is a magnetically absorbable material, the magnetism generated by the electromagnet 333 when it is energized can perform adsorption work, thereby improving the cleaning effect of the magnetically absorbable material; if the workpiece is a non-magnetically absorbable material, such as aluminum alloy, the negative pressure generated by the negative pressure pump is mainly used to absorb the debris and burrs into the adsorption groove 332. The size of the negative pressure hole 334 is smaller than the debris and burrs, reducing the probability of debris and burrs entering the negative pressure branch pipe, thereby achieving the purpose of adsorption. The two adsorption methods provided by this adsorption component 33 are different from the method of using a brush for cleaning. If the adsorption method is used for cleaning, some debris stuck in the countersunk screws on the surface of the support platform 12 can also be cleaned, thereby ensuring the actual cleaning efficiency of the device.

[0043] In order to reduce the debris and burrs generated during high-speed stamping from entering the profiling drive box 2, as shown in the following example: Figure 3 and Figure 6 As shown, the outer side of the contoured track hole 21 provided by the present invention is provided with a barrier brush 23 distributed along its length. The barrier brush 23 uses densely distributed bristles to prevent debris and burrs from passing through the contoured track hole 21 and entering the contoured drive box 2. On the other hand, when the roller cleaning component 3 passes by the position of the bristles, the bristles will be compressed accordingly, making an effective movement path for the roller cleaning component 3. After the roller cleaning component 3 has completely passed, the bristles automatically restore their deformation and continue to play a shielding role.

[0044] In order to improve the transmission performance of the drive mechanism 22 to the roller-type cleaning component 3, the drive mechanism 22 provided by the present invention includes a transmission belt 221 distributed along the profiling track hole 21, the width of the transmission belt 221 being greater than the width of the transmission contact surface between the transmission belt 221 and the roller-type cleaning component 3, the interior of the profiling drive box 2 is provided with a curved plate 24 that is limitedly engaged with the transmission belt 221, the curved surface trajectory of the curved plate 24 being consistent with the transmission trajectory of the transmission belt 221, the input end of the transmission belt 221 being provided with a transmission roller, and the power end of the transmission roller being provided with a transmission motor. Among them, the transmission motor provides transmission power to the transmission belt 221 through the transmission roller, and the transmission belt 221 maintains an effective transmission path under the clamping of the outer peripheral surface of the curved plate 24 and the inner wall of the track of the profiling track hole 21, and the transmission path is substantially consistent with the path of the profiling track hole 21. Therefore, the transmission belt 221 can drive the traction head 32 that is engaged with it to complete the complete profiling movement path, thereby ensuring the cleaning effect of the roller-type cleaning component 3 on the support platform 12 and the lower mold 11. In order to improve the transmission efficiency of the transmission belt 221 and the traction head 32, the transmission belt 221 can adopt a V-belt with transmission teeth, and the outer surface of the traction head 32 is provided with gears that cooperate with the V-belt, and the part where the transmission belt 221 cooperates with the curved plate 24 adopts a smooth surface, thereby ensuring the actual transmission efficiency of the transmission belt 221 and the traction head 32.

[0045] To enhance the structural strength of the contoured drive box 2, the contoured drive box 2 provided by the present invention is provided with a plurality of reinforcement sleeves 25 symmetrically distributed about the transmission track of the transmission belt 221 on one side, and a plurality of reinforcement rods 26 nested one-to-one with the reinforcement sleeves 25 on the other side. The contoured drive box 2 comprises a box body and a box cover. The contoured track holes 21 and the reinforcement sleeves are provided on the box surface of the box body, while the curved plate 24 and the reinforcement rods are provided on the box cover. Therefore, after the box cover is assembled to the box body, the curved plate 24 effectively corresponds to the transmission belt 221 to complete the position limiting, and the reinforcement rods 26 form a nested relationship with the reinforcement sleeves 25, thereby ensuring the overall structural strength of the contoured drive box 2 and also facilitating the actual driving performance of the drive mechanism 22 on the roller-type cleaning component 3.

[0046] The adsorption assembly 33 provided by the present invention is mainly used to adsorb waste chips that fall from the workpiece. As for the dust in the workshop, the present invention adopts a different design. For example, two mounting plates 6 are symmetrically provided on the front side of the body 1 provided by the present invention. Wind pressure devices 7 are provided on the two mounting plates 6, and one of the wind pressure devices 7 is a positive pressure device, and the other wind pressure device 7 is a negative pressure device. The positive pressure device is used to provide positive pressure in the direction of the support platform 12, and the negative pressure device is used to adsorb the dust blown up by the positive pressure device. In this way, the positive pressure device reduces the adhesion of dust by providing positive pressure, and the negative pressure device provides negative pressure to suck away the suspended dust. For the positive pressure device and the negative pressure device, there is no need to provide particularly large power, as long as the power requirements for blowing up and sucking away dust are met. Moreover, when the positive pressure device and the negative pressure device are working continuously, there will not be a lot of dust to be handled per unit time, so providing positive pressure devices and negative pressure devices of general power can meet the requirements.

[0047] In order to improve the matching performance of the mounting plate 6 and the wind pressure device 7 with the body 1, the mounting plate 6 provided by the present invention includes an angular section 61, which is used to match the edge surface of the body 1 for installation. A circular section 62 is provided on the angular section 61, and a plurality of heat dissipation grille holes 63 distributed along its length are provided on the circular section 62. A fracture 64 is provided on one side of the circular section 62. The wind pressure device 7 includes a vertically long strip of air box 71. The air box 71 is provided with several air holes 72 on its side facing the middle of the body 1. At least one working fan is provided inside the air box 71. A buckle groove 73 matching the fracture 64 is provided on the side of the air box 71. An adjusting bolt 74 is provided on the other side of the air box 71. The adjusting bolt 74 matches the adjusting hole 65 provided on the mounting plate 6. Among them, the surface of the bellows 71 for opening the air holes 72 can be designed to be an inclined surface and face the stamping working surface. By setting the bellows 71, the space utilization rate of the wind pressure device 7 can be limited to a higher level, and multiple relatively small fans can be used to provide positive pressure / negative pressure at the same time, thereby meeting the needs of dust cleaning.

[0048] Furthermore, the actual height of the bellows 71 relative to the mounting plate 6 can be adjusted by changing the actual mating position of the adjustment bolts 74 and the adjustment holes 65. The mounting plate 6 mates with two edge faces of the beams and columns of the machine body 1 and is secured with bolts. The bellows 71 and mounting plate 6 are also secured via a circular design and the adjustment bolts 74, providing a stable mounting base for the bellows 71. Furthermore, the rational design of the mounting plate 6 improves the space utilization of the bellows 71, providing adjustment margin for the bellows 71, and also provides a certain amount of heat dissipation through the heat dissipation grille holes 63.

[0049] like Figure 2As shown, in order to prevent the stamping debris and burrs from splashing toward the rear side of the machine body, the present invention also provides a baffle on the rear side of the machine body, and a feeding port for feeding materials is provided on the baffle. The edge of the feeding port is covered with long bristles or anti-static curtains, which can not only block the waste chips but also affect the feeding of materials.

[0050] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
