Description

Technical Field

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

[0002] A high-speed press is an efficient device suitable for large-batch and high-precision stamping production. Its core features are reflected in aspects such as high speed, high precision, high automation, and specialized design. Motor-driven presses have outstanding performance in the fields of precision manufacturing and green production due to advantages such as high precision, energy conservation, and flexibility, such as the press drive device for a press and the press with the press drive device disclosed in CN201580056723.6. The advantages of motor-driven presses include high precision and stability, energy-saving and high efficiency, flexible production, and intelligence and safety. Since the high-speed press operates continuously, 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 the staff at the stamping station holding a cleaning brush. With the requirements of automated workshops, many operation contents have been gradually replaced by mechanical structures, including the cleaning operation on the surface of the press.

[0003] A gas-blowing cleaning device for a press platform disclosed in the existing patent CN202222691143.4 uses the gas-blowing method for cleaning, and a press with a cleaning function disclosed in CN202022105331.5 uses a flat-pushing method. The cleaning operations of these devices rely on the flatness of the working surface of the press. However, for a high-speed press that needs to install a lower die, after installing the lower die, it is impossible to clean the debris and fallen burrs on the surface of the lower die, and even the mounting base surface of the lower die cannot be cleaned mechanically. Moreover, for devices that rely entirely on the gas-blowing method to achieve the cleaning operation, since the debris and fallen burrs are different from dust, the debris and fallen burrs have a certain mass. If the gas-blowing power is small, the cleaning function cannot be achieved, and if the gas-blowing power is large, it will cause the debris and fallen burrs to splash secondary, affecting the actual cleaning effect and operation safety of this station. Secondly, some cleaning devices occupy the stamping plane of the press. Although it does not affect the workpiece being stamped and formed, the debris and fallen burrs will also directly fall on the surface of the cleaning device, and mostly rely on manual cleaning, so their cleaning performance still needs to be improved.

[0032] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left" and "right" hereinafter only represent the same directions as the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0034] Embodiment, as Figures 1 to 12 As shown, a press with a self-cleaning device provided by the present invention includes a machine body 1. A stamping drive box, a lifting slider, an upper die, a lower die 11, a support platform 12 for installing the lower die 11, and a buffer device for providing a safety mechanism are arranged on the machine body 1. Among them, the upper die and the lower die 11 are selected according to the processing requirements of the actual workpiece and are respectively installed on the lifting slider and the support platform 12. These structures are mature existing technologies and will not be elaborated herein in this embodiment. In order to ensure the quality of the working surface of the press, the present invention provides a cleaning device controlled by a motor to achieve automatic cleaning, and this 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, the interior of the profiling drive box 2 is provided with a driving mechanism 22, and a roller cleaning component 3 connected to the driving mechanism 22 is provided between the two profiling drive boxes 2. The roller 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 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 tracks 4 for concealedly accommodating the roller cleaning component are provided in the positioning grooves 13. A collection box 5 for collecting debris and fallen burrs released by the roller cleaning component is provided below the support platform 12.

[0036] In the present device, two profiling drive boxes 2 are distributed on the left and right sides of the support platform 12. Since the cross section of the lower mold 11 must be smaller than the cross section of the support platform 12, the profiling drive box 2 does not affect the stamping and parting of the upper mold and the lower mold 11. Furthermore, the roller-type cleaning component 3 is located in the support track 4 when the cleaning work is not performed, and the support track 4 is concealedly installed on the front and back sides of the support platform 12, so the roller-type cleaning component 3 does not affect the stamping and parting of the upper mold and the lower mold 11, and the debris and burrs generated during the stamping process will basically not fall on the roller-type cleaning component 3. The working principle of the profiling drive box 2 and the roller-type cleaning component 3 is that the driving mechanism 22 in the profiling drive box 2 provides traction power for the roller-type cleaning component 3, the roller-type cleaning component 3 is removed from the support track 4, and can be orderly moved along the surface of the support platform 12 and the lower mold 11, and its adsorption working surface is always in a state facing the surface of the support platform 12 and the lower mold 11 due to the self-weight factor, and the debris and fallen burrs are taken away by adsorption during the movement of the roller-type cleaning component 3, and finally at the terminal position close to the rear side of the body 1, the adsorbed debris and burrs are released into the collection box 5 together, so as to achieve the function 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 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, with high space utilization and high safety, and is suitable for large-scale promotion.

[0037] In order to improve the cleaning efficiency of the roller cleaning component 3, the profiling 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 towards the support track 4, and the other end of the L-shaped segment 211 is connected to the convex segment 212 upwards. The bottom segment, side segment, and top segment of the convex segment 212 are parallel to the top surface of the support platform 12, the side surface of the lower mold 11, and the top surface of the lower mold 11 respectively. Among them, the L-shaped segment 211 provides a moving path for the roller cleaning component 3 to enter and exit the support track 4, enabling it to be effectively hidden under the coverage of the support platform 12 in the non-working state; the convex segment 212 provides a moving path for the roller cleaning component 3 along the upper surface of the support platform 12, the side surface of the lower mold 11, and the top surface of the lower mold 11, especially the upper surface of the support platform 12 and the top surface of the lower mold 11, thereby ensuring the effectiveness of the cleaning path of the roller cleaning component 3 and further facilitating the efficiency of the cleaning work.

[0038] As Figures 8 to 10 shown, the roller cleaning component 3 includes an outer shaft 31. Shaft heads 311 are 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 driving mechanism 22. A limiting shoulder can be provided on the side surface of the traction head 32 and can be in rolling cooperation with the profiling track hole 21. A plurality of adsorption components 33 are provided on the side surface of the outer shaft 31. 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 rotate flexibly in the nested surface of the traction head 32; due to the arrangement of the adsorption components 33, the center of gravity of the roller cleaning component 3 is basically closer to the adsorption components 33. Therefore, during the continuous movement of the roller cleaning component 3, the adsorption components 33 can maintain the downward posture to the maximum extent. Therefore, when the adsorption components 33 pass by the upper surface of the support platform 12 and the top surface of the lower mold 11, their working surfaces can always face the object to be cleaned.

[0039] In order to improve the storage effect of the support track 4 on the roller cleaning component 3, the support track 4 provided by the present invention includes a U-shaped groove with openings facing the front side and the rear side of the machine body 1. The upper and lower groove surfaces of the U-shaped groove form a shelter surface for the roller cleaning component 3. A horizontal T-shaped block is provided in the U-shaped groove. An arc-shaped groove matching the outer shaft 31 is provided at the end of the T-shaped block. In this way, after the outer shaft 31 enters the support track 4, it can be kept in a manner that the side surface is in contact and the upper and lower surfaces are suspended, playing a limiting role and not hitting the adsorption components 33.

[0040] Considering the limited working area of the roller-type cleaning component 3, in order to ensure the cleaning ability of the cleaning process, the present invention allows the adsorption component 33 to move axially back and forth. Specifically, the multiple adsorption components 33 provided by the present invention are divided into two rows and are symmetrically distributed near the axial plane of the outer shaft 31, and the adsorption components 33 in adjacent rows are axially staggered. The side of the outer shaft 31 is provided with multiple guide holes 312 corresponding to the adsorption components 33 one by one and for the adsorption components 33 to move axially. The inner part of the outer shaft 31 is provided with a cylindrical cam inner shaft 34, and the side of the cylindrical cam inner shaft 34 is provided with a cylindrical cam track 35 that is movably matched with the adsorption component 33, and 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 cylindrical cam inner shaft 34, and the cylindrical cam inner shaft 34 adopts a stepping rotation method to convert its rotational motion into a reciprocating translational motion of the adsorption component 33. 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 and passes 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] In order to improve the cleaning efficiency of the roller-type cleaning component 3, the adsorption assembly 33 includes an adsorption seat 331, the adsorption seat 331 is provided with an adsorption groove 332, the adsorption groove 332 is provided with an electromagnet 333 and a negative pressure hole 334 symmetrically distributed about the electromagnet 333, the negative pressure hole 334 adopts a narrow flat hole design, the back side of the adsorption seat 331 is provided with a pair of guide posts 335 connected with the negative pressure holes 334, the guide posts 335 cooperate with the cylindrical cam track 35, the cylindrical cam inner shaft 34 is a hollow structure and a negative pressure branch pipe 336 connected with the guide posts 335 is provided therein, the negative pressure branch pipe 336 is connected with 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, and the negative pressure pump can be arranged inside the machine body. In this case, the adsorption component 33 has another advantage when driven by the inner shaft 34 of the cylindrical cam to make axial reciprocating movement. 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 level of the adsorption end of the adsorption component 33 to other positions of the adsorption groove 332 through reciprocating movement, thereby filling the vacant space in the adsorption groove 332, avoiding excessive accumulation of debris and burrs in the 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 for connecting the coil to a power source, and the adsorption surface of the iron core faces the outside of the adsorption groove 332. In this way, if the workpiece to be processed is a magnetizable material, the magnetism generated by the energized electromagnet 333 can perform the adsorption work, thereby improving the cleaning effect on magnetizable materials; if the workpiece to be processed is a non-magnetizable material, such as aluminum alloy, the negative pressure generated by the negative pressure pump mainly sucks the debris and burrs into the adsorption groove 332. The size of the negative pressure holes 334 is smaller than that of the debris and burrs, reducing the probability of the 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 brush bristles for cleaning. If the adsorption method is used for cleaning, the debris stuck in the countersunk screws on the surface of the support platform 12 can also be cleaned, thus ensuring the actual cleaning efficiency of this device.

[0043] In order to prevent the debris and burrs generated during the high-speed stamping process from entering the profiling drive box 2, as Figure 3 and Figure 6 shown, a partition brush 23 distributed along its length direction is provided outside the profiling track hole 21 of the present invention. The partition brush 23 uses dense brush bristles. On the one hand, it can prevent debris and burrs from passing through the profiling track hole 21 and entering the profiling drive box 2. On the other hand, when the roller-type cleaning component 3 passes through the position of the brush bristles, the brush bristles can be compressed accordingly, leaving an effective moving path for the roller-type cleaning component 3. After the roller-type cleaning component 3 has completely passed, the brush bristles automatically recover their deformation and continue to play the role of blocking.

[0044] In order to improve the transmission performance of the drive mechanism 22 to the roller shaft 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 is greater than the width of its transmission contact surface with the roller shaft type cleaning component 3. Inside the profiling drive box 2, there is a curved panel 24 that is in limiting cooperation with the transmission belt 221. The curved surface track of the curved panel 24 is consistent with the transmission track of the transmission belt 221. At the input end of the transmission belt 221, there is a transmission roller, and at the power end of the transmission roller, there is a transmission motor. Among them, the transmission motor provides transmission power to the transmission belt 221 through the transmission roller. The transmission belt 221 maintains an effective transmission path under the clamping of the outer peripheral surface of the curved panel 24 and the inner wall of the track of the profiling track hole 21. This transmission path is basically consistent with the path of the profiling track hole 21. Therefore, the transmission belt 221 can drive the traction head 32 in transmission cooperation with it to complete a complete profiling movement path, thereby ensuring the cleaning effect of the roller shaft type cleaning component 3 on the support platform 12 and the lower mold 11. In order to improve the transmission efficiency between the transmission belt 221 and the traction head 32, the transmission belt 221 can adopt a V-belt with teeth on it, and gears matching the V-belt are arranged on the outer surface of the traction head 32, while the part of the transmission belt 221 cooperating with the curved panel 24 adopts a smooth surface, so as to ensure the actual transmission efficiency between the transmission belt 221 and the traction head 32.

[0045] In order to improve the structural strength of the profiling drive box 2, on one side of the profiling drive box 2 provided by the present invention, there are a plurality of reinforcing sleeves 25 symmetrically distributed with respect to the transmission track of the transmission belt 221, and on the other side of the profiling drive box 2, there are a plurality of reinforcing rods 26 nested with the reinforcing sleeves 25 one by one. The profiling drive box 2 includes a box body and a box cover. The profiling track hole 21 and the reinforcing sleeves are arranged on the box surface of the box body, while the curved panel 24 and the reinforcing rods are arranged on the box cover. Therefore, after the box cover is assembled to the box body, the curved panel 24 effectively corresponds to the transmission belt 221 to complete the limiting, and the reinforcing rods 26 form a nested relationship with the reinforcing sleeves 25, thus ensuring the overall structural strength of the profiling drive box 2 and also being beneficial to ensuring the actual driving performance of the drive mechanism 22 on the roller shaft type cleaning component 3.

[0046] The adsorption component 33 provided by the present invention is mainly used to adsorb the waste chips falling from the workpiece. For the dust in the workshop, the present invention adopts a different design. For example, two mounting plates 6 are symmetrically arranged on the front side of the body 1 provided by the present invention. A wind pressure device 7 is arranged 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 towards 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 ability of the 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, it is not necessary to provide a particularly large power, as long as it meets the power requirements for blowing up the dust and sucking away the dust. Moreover, when the positive pressure device and the negative pressure device work continuously, there will not be a particularly large amount of dust to be processed per unit time. Therefore, providing positive pressure devices and negative pressure devices with general power can meet the requirements.

[0047] In order to improve the cooperation performance between the mounting plate 6, the wind pressure device 7 and the body 1, the mounting plate 6 provided by the present invention includes an angular section 61, and the angular section 61 is used for fitting and installing with the edge surface of the body 1. A return section 62 is arranged on the angular section 61, and a plurality of heat dissipation grid holes 63 are arranged along the length direction of the return section 62. A break 64 is arranged on one side of the return section 62. The wind pressure device 7 includes a vertically long wind box 71. A number of air holes 72 are arranged on the side of the wind box 71 facing the middle of the body 1. At least one working fan is arranged inside the wind box 71. A buckle groove 73 for cooperating with the break 64 is arranged on the side surface of the wind box 71. An adjusting bolt 74 is arranged on the other side of the wind box 71, and the adjusting bolt 74 cooperates with an adjusting hole 65 arranged on the mounting plate 6. Among them, the surface of the wind box 71 for opening the air holes 72 can be designed as an inclined surface and facing the stamping working surface. By arranging the wind box 71, the space utilization rate of the wind pressure device 7 can be limited to a relatively high level, and a plurality of relatively small-volume fans are used to provide positive pressure / negative pressure simultaneously, thereby meeting the need for dust cleaning.

[0048] Furthermore, by changing the actual cooperation position between the adjusting bolt 74 and the adjusting hole 65, the purpose of adjusting the actual height between the wind box 71 and the mounting plate 6 can be achieved. The mounting plate 6 cooperates with the two edge surfaces of the beam column of the body 1 and is fixed by bolts, and the wind box 71 and the mounting plate 6 are also fixed through a return design and the adjusting bolt 74, thereby providing a stable installation foundation for the wind box 71. Moreover, through reasonable design of the mounting plate 6, the space utilization rate of the wind box 71 is improved, an adjustment margin is provided for the wind box 71, and certain heat dissipation capacity is also provided through the heat dissipation grid holes 63.

[0049] Such as Figure 2As shown in the figure, in order to prevent the debris and burrs generated by stamping from splashing towards the rear side of the machine body, the present invention further provides a baffle on the rear side of the machine body. A material passing opening for material passing is provided on the baffle, and the edge of the material passing opening is covered with long bristles or an anti-static curtain cloth, which can not only block waste chips but also affect material passing.
