Description

Technical Field

[0001] The present invention relates to the technical field of shielding cover processing, and in particular to a shielding cover molding device and a process thereof. Background Art

[0002] Shielding covers are devices used to shield electromagnetic radiation or protect against electromagnetic waves. They are usually made of materials with good electrical conductivity. When producing shielding covers, a punching machine is needed to punch the material strip into the desired shape. The punching die is an important part of the punching machine, and the punching machine will be equipped with an oiling device to oil the material strip. When the material strip is punched by the punching machine, the stamping oil will be applied to the surface of the material strip through the oiling device. The additives in the stamping oil can form a uniform coating on the surface of the material strip. This coating can not only improve the surface finish of the material strip, but also reduce scratches and wear caused by the stamping process.

[0003] When the material strip passes through the oiling device for oiling, the material strip will first pass through the two oiling rollers in the oiling device and be installed at the stamping die. Then the stamping oil will drip onto the oiling roller of the oiling device through the oiling head on the oiling device. When the material strip passes through the stamping die for stamping, the material strip will intermittently slide to the stamping die. The material strip in the sliding state can drive the oiling roller of the oiling device to rotate, and the stamping oil on the oiling roller will be smeared on the surface of the material strip. However, when the oiling roller is in contact and friction with the material strip for a long time, its working area will heat up and be in a high temperature state. When the oiling head drops the stamping oil on the working area of ​​the oiling roller, the stamping oil is oiled. The high temperature in the working area of ​​the roller causes the fluidity of the oil to increase and the viscosity to decrease. When the viscosity decreases, the thickness of the oil film may decrease, resulting in a decrease in the lubrication effect. When the oil roller rotates, the stamping oil may be thrown to the outside of the oil roller due to the centrifugal force, which may cause the stamping oil to flow to both sides of the oil roller, especially when the viscosity of the stamping oil is low. The two sides of the oil roller are non-working areas, and the stamping oil that remains for a long time may form an insulating layer, which hinders the transfer and dissipation of heat, which will cause the surface temperature of the oil roller to increase, thereby affecting the performance and life of the oil roller. Summary of the invention

[0004] The present invention provides a shielding cover molding device and a process thereof, aiming to solve the problem in the related art that the working area of ​​the oil coating roller will be heated to high temperature when working for a long time, resulting in increased fluidity of the oil and reduced viscosity.

DETAILED DESCRIPTION

[0031] 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.

[0032] Embodiment 1 like Figure 1 , Figure 2 and Fig.11As shown, a shielding cover forming device of the present invention comprises: a punching machine 10, an oil distributing roller mechanism 11 and a shielding cover 13, wherein the shielding cover 13 is punched and formed by the punching machine 10, the oil distributing roller mechanism 11 is installed on one side of the punching machine 10, the oil distributing roller mechanism 11 comprises a frame 110, a plurality of oil dripping heads 111 arranged at equal distances are installed on the top of the frame 110, and the plurality of oil dripping heads 111 are arranged on the frame 110 in a transverse manner, an oil delivery assembly 112 is installed on the frame 110, and the inner bottom of the frame 110 is provided with a plurality of oil dripping heads 111 arranged at equal distances. Two lower bearing seats 113 are installed on the top, and a lower transmission roller 114 is rotatably connected between the two lower bearing seats 113. Upper bearing seats 115 are installed on the top of the two lower bearing seats 113. An upper transmission roller 116 is rotatably connected between the two upper bearing seats 115, and the upper transmission roller 116 is located below the oil drip head 111. A channel is provided between the upper transmission roller 116 and the lower transmission roller 114 for accommodating and conveying the material strip, so as to facilitate the material strip to be stamped into the shielding cover 13 through the stamping machine 10.

[0033] The oil delivery assembly 112 includes an oil storage portion installed on the stamping machine table 10, a connecting pipe is installed on one side of the frame 110, and an oil delivery pipe is connected between the connecting pipe and the oil storage portion. The stamping oil inside the oil storage portion can flow to the frame 110 through the oil delivery pipe and the connecting pipe, and flow to the surface of the upper transmission roller 116 through the oil drip head 111, so that the stamping oil can be applied to the surface of the material belt when the upper transmission roller 116 conveys the material belt.

[0034] When in use, the material strip is passed through the channel between the upper transmission roller 116 and the lower transmission roller 114 and installed at the punching position of the stamping machine 10, and the stamping oil inside the oil storage part flows to the connecting pipe through the oil pipe, and the stamping oil is dripped to the working area of ​​the upper transmission roller 116 through the oil dripping head 111. As the material strip is conveyed and stamped on the stamping machine 10, the upper transmission roller 116 and the lower transmission roller 114 are driven to rotate when the material strip conveys the stamping machine 10, and the stamping oil on the surface of the upper transmission roller 116 is smeared on the upper surface of the material strip. Part of the stamping oil of the upper transmission roller 116 and the oil on the surface of the material strip squeezed and diffused by the upper transmission roller 116 will drip onto the lower transmission roller 114 and will flow to the inner bottom of the frame 110 for aggregation. As the lower transmission roller 114 rotates, the stamping oil on the surface of the lower transmission roller 114 will be smeared on the lower surface of the material strip, thereby facilitating the material strip to be stamped into the shielding cover 13 through the stamping machine 10.

[0035] Embodiment 2 Although the above-mentioned device can apply stamping oil to the surface of the material strip for subsequent stamping and forming, the upper transmission roller 116 will generate heat due to friction with the material strip when working for a long time, so that the working area of ​​the upper transmission roller 116 will be in a high temperature state. When the oil drip head 111 drips the stamping oil on the working area of ​​the upper transmission roller 116, the stamping oil is affected by the high temperature of the working area of ​​the upper transmission roller 116, thereby increasing the fluidity of the oil and reducing the viscosity. When the viscosity decreases, the thickness of the oil film may decrease, resulting in a decrease in the lubrication effect. When the upper transmission roller 116 rotates, due to the action of centrifugal force, the stamping oil may be thrown to both sides of the upper transmission roller 116, especially when the viscosity of the stamping oil is low. In addition, the two sides of the upper transmission roller 116 are non-working areas, and the stamping oil remaining for a long time may form a heat insulation layer, which hinders the transfer and dissipation of heat, which will cause the surface temperature of the upper transmission roller 116 to increase, thereby affecting the performance and life of the upper transmission roller 116. In view of this, improvements are made on the basis of Example 1.

[0036] refer to Figure 1-Figure 7 As shown, a mounting box 12 is fixed between the two upper bearing seats 115, a bottom opening 120 is provided at the bottom of the mounting box 12, and the bottom opening 120 is located in the middle of the bottom surface of the mounting box 12, a side opening 121 is provided on the side of the mounting box 12 facing the punching machine table 10, and an observation port is provided on the side of the mounting box 12 away from the upper transmission roller 116, and an L-shaped baffle is rotatably connected to the inner wall of the observation port.

[0037] refer to Figure 1-Figure 6 As shown, an oil collecting mechanism is installed inside the installation box 12, which can scrape the stamping oil in the non-working area of ​​the upper transmission roller 116, so as to maintain the performance of the upper transmission roller 116.

[0038] The oil collecting mechanism includes an oil collecting assembly 20 and a filtering assembly 21. The oil collecting assembly 20 is used to clean and collect the stamping oil in the non-working area of ​​the upper transmission roller 116, and the filtering assembly 21 can filter iron filings and other impurities contained in the stamping oil.

[0039] The oil collecting assembly 20 includes a collecting box 201 fixed to the middle of the inner wall of the mounting box 12, and the opening of the collecting box 201 faces upward. Flow ports 202 are provided on both sides of the collecting box 201, and the stamping oil can flow into the interior of the collecting box 201 through the flow ports 202, thereby facilitating the collection of the stamping oil. Two symmetrical guide triangles are fixed to the inner bottom wall of the collecting box 201, and the top of the guide triangle is flush with the bottom of the flow port 202.

[0040] Mounting seats 203 are fixed on both sides of the collecting box 201, and the side of the mounting seat 203 away from the collecting box 201 is fixed on the inner wall of the mounting box 12, the two mounting seats 203 are symmetrical with the collecting box 201 as the center, the mounting seat 203 is L-shaped, the mounting seat 203 is composed of an arc segment and a triangular block, the bottom of the arc segment is fixed to the top of the triangular block, the arc segment has an arc surface on the side facing the upper transmission roller 116, and the arc surface is adapted to the surface of the upper transmission roller 116, the arc segment has an arc guide surface on the side away from the upper transmission roller 116, a tip is formed between the arc guide surface and the arc surface, which is used to scrape the stamping oil on the surface of the upper transmission roller 116, and flow to the triangular block through the arc guide surface to the inside of the collecting box 201 for collection, the bottom end of the triangular block is flush with the bottom of the flow port 202, the top of the triangular block is higher than its bottom end, and an arc guide portion is fixed on the side of the arc surface close to the collecting box 201.

[0041] Since the upper transmission roller 116 rotates downward, when the upper transmission roller 116 rotates, the tip will scrape the stamping oil and attached iron filings on the surface of the upper transmission roller 116. At this time, the stamping oil and iron filings will flow toward the slope of the triangular block surface. At this time, the filter component 21 can filter the iron filings in the stamping oil, and the stamping oil can flow through the slope of the triangular block surface to the flow port 202 to the inside of the collection box 201 to complete the collection.

[0042] The filter assembly 21 includes an inclined plate 210 arranged on the surface of the triangular block, and a rotating shaft is rotatably connected between the bottom side wall of the inclined plate 210 and the inner wall of the installation box 12, and the bottom end of the inclined plate 210 is located at the top of the triangular block, and the top of the inclined plate 210 is located below the arc-shaped guide portion. An opening 211 is provided on the inclined plate 210, and a first filter screen 212 is fixed to the inner wall of the opening 211 for filtering the stamping oil to maintain the cleanliness of the stamping oil. A circular hole 213 is provided on one side of the triangular block close to the collecting box 201, and a lifting column 214 is slidably connected to the inner wall of the circular hole 213. A hinged ball is connected to the top of the lifting column 214 and the bottom of the top of the inclined plate 210, and the cooperation of the circular hole 213, the lifting column 214 and the hinged ball is used to support the inclined plate 210 to maintain the stability of the inclined plate 210.

[0043] When the stamping oil on the surface of the arc guide surface flows toward the surface of the inclined plate 210, the first filter 212 can filter the stamping oil so that iron filings and other impurities can remain on the surface of the first filter 212, and the stamping oil flows through the first filter 212 onto the slope of the triangular block. Since the inclined plate 210 is in an inclined state, when the arc guide surface continues to scrape the stamping oil and iron filings on the surface of the upper transmission roller 116, the stamping oil and iron filings will impact the filtered material remaining on the surface of the inclined plate 210, so that the filtered impurities can roll down and accumulate at the bottom end of the inclined plate 210.

[0044] refer to Figure 4 , Figure 6 and Figure 7 As shown, an oil spreading assembly 30 is installed on the collection box 201 for directing the stamping oil inside the collection box 201 to the surface of the material strip, thereby pre-treating the material strip with oil.

[0045] The oil spreading assembly 30 includes a connecting head 31 fixedly connected to the bottom of the collecting box 201, an oil drain head 33 is arranged on the lower side of the connecting head 31, and a soft oil pipe 32 is connected between the top of the oil drain head 33 and the bottom of the connecting head 31. The stamping oil collected inside the collecting box 201 flows to the oil drain head 33 through the connecting head 31 and the soft oil pipe 32 and is discharged, so that the stamping oil is applied to the surface of the material strip in advance, so that the upper transmission roller 116 can evenly apply the stamping oil to the surface of the material strip.

[0046] A hydraulic cylinder 34 is fixed to the inner bottom wall of the mounting box 12, and the piston rod end of the hydraulic cylinder 34 is fixed to the outer surface of the oil drain head 33, which is used to drive the oil drain head 33 to slide horizontally, so that the stamping oil can be evenly dripped on the surface of the material belt. Two limiting slide rails 35 are fixed to the bottom of the collecting box 201, and the two limiting slide rails 35 are symmetrical with the oil drain head 33 as the center. Two supporting arms 36 are installed on the outer surface of the oil drain head 33, and the two supporting arms 36 are symmetrical with the oil drain head 33 as the center, and the supporting arms 36 are slidably connected to the inside of the corresponding limiting slide rails 35. The limiting slide rails 35 cooperate with the supporting arms 36 to limit the oil drain head 33, so as to maintain the stability of the oil drain head 33 when sliding horizontally.

[0047] Since the connecting head 31 is located in the middle of the bottom end of the collecting box 201, and the connecting head 31 is located in the middle of the bottom ends of the two guiding triangle blocks, when the stamping oil on the slope of the triangle block flows to the inside of the collecting box 201 through the flow port 202, the stamping oil can flow to the connecting head 31 through the surface of the guiding triangle block, and the connecting head 31 flows the stamping oil to the oil discharge head 33 through the soft oil pipe 32 and discharges it to the surface of the material belt below, and the piston rod of the hydraulic cylinder 34 drives the oil discharge head 33 to slide repeatedly at both ends of the track of the limiting slide rail 35; it should be noted that the speed of the piston rod of the hydraulic cylinder 34 can be adjusted according to the speed of the material belt during transportation, so as to maintain the oil discharge head 33 so that the stamping oil can be evenly laid on the surface of the material belt.

[0048] refer to Figure 4 , Figure 6 and Figure 7 As shown, a vibration assembly 40 is installed on the support arm 36, which can make the inclined plate 210 slide up and down to produce shaking, thereby preventing impurities from accumulating on the surface of the first filter screen 212 and causing blockage.

[0049] The vibration assembly 40 includes a limit support shaft 41 fixed between the two support arms 36, and two arc-shaped linkage plates 42 are fixed on the surface of the limit support shaft 41, and the two arc-shaped linkage plates 42 are symmetrical with the limit support shaft 41 as the center, and the arc-shaped linkage plate 42 has an arc surface on the side away from the limit support shaft 41, and an arc-shaped linkage block 43 is fixed to the bottom of the lifting column 214, and the bottom of the arc-shaped linkage block 43 has an arc surface, and a reset member 44 is fixed between the top of the arc-shaped linkage block 43 and the bottom of the triangular block, which is used to support the lifting column 214, so as to facilitate the reset of the inclined plate 210.

[0050] When the oil drain head 33 slides to either end of the limiting slide rail 35, the arc surface of the arc linkage plate 42 will press against the arc surface of the corresponding arc linkage block 43, and the arc linkage block 43 drives the lifting column 214 to move upward inside the circular hole 213 through the arc linkage block 43, and the lifting column 214 drives the inclined plate 210 to move up, thereby increasing the inclination angle of the inclined plate 210, so as to facilitate the flow of the filtered material on the surface of the first filter screen 212 to its bottom for accumulation. When the arc linkage block 43 is separated from the arc linkage plate 42, the reset member 44 will drive the inclined plate 210 to reset through the lifting column 214. At this time, the inclined plate 210 will have a shaking force, thereby applying vibration to the first filter screen 212 to prevent the filtered material on the surface of the first filter screen 212 from accumulating and clogging.

[0051] The stamping oil in the non-working area on both sides of the upper transmission roller 116 can be scraped and collected through the oil collecting component 20, and the filter component 21 can filter the stamping oil scraped by the oil collecting component 20 to screen out iron filings and other impurities in the stamping oil, and the filtered stamping oil can flow onto the surface of the material belt through the oil spreading component 30, thereby improving the uniformity of the oil coating of the material belt by the upper transmission roller 116. At the same time, the oil spreading component 30 cooperates with the vibration component 40 to increase the inclination angle of the filter component 21, so that the filter component 21 is in a shaking state, thereby maintaining the filtering performance of the filter component 21 for the stamping oil.

[0052] Embodiment 3 Since the working area of ​​the upper drive roller 116 is continuously in contact with the surface of the material belt, the iron filings and impurities attached to the surface of the upper drive roller 116 will be tightly attached to the surface of the upper drive roller 116 through the extrusion with the material belt, and if the iron filings and impurities attached to the working area of ​​the upper drive roller 116 are not cleaned in time, it will affect the oiling performance of the upper drive roller 116 and the service life of the upper drive roller 116, and will also cause uneven application of the stamping oil. In view of this, improvements are made on the basis of Example 2.

[0053] refer to Figure 8 , Fig. 9 and Fig.10As shown, a cleaning assembly 50 is installed on the collection box 201 for cleaning the working area of ​​the upper transmission roller 116 , so as to maintain the oil coating performance of the working area of ​​the upper transmission roller 116 .

[0054] The cleaning assembly 50 includes a sliding plate 51 slidably connected to a side wall of the collection box 201 , a support column is fixed between the outer surface of the oil drain head 33 and the sliding plate 51 , and an arc-shaped member 52 is provided on the side of the sliding plate 51 away from the collection box 201 .

[0055] The inner concave surface of the arc-shaped member 52 is matched with the surface of the upper transmission roller 116. Both sides of the arc-shaped member 52 have arc-shaped surfaces. A connecting port 53 and an oil drain port 55 are opened on the arc-shaped member 52. The connecting port 53 and the oil drain port 55 are connected, and the connecting port 53 is located at the arc-shaped surface, and the oil drain port 55 is located on the inner concave surface of the arc-shaped member 52. A second filter screen 54 is fixed on the inner wall of the connecting port 53 for filtering iron filings and other impurities in the stamping oil, thereby maintaining the cleanliness of the stamping oil flowing to the upper transmission roller 116.

[0056] A circular hole is provided on the sliding plate 51, and the inner wall of the circular hole is rotatably connected to a limiting shaft 56, and one end of the limiting shaft 56 is fixed to one side of the sliding plate 51, and a linkage bar 57 is fixed to the outer surface of the limiting shaft 56, and two push bars 58 are fixed to the top of the collecting box 201. The push bar 58 cooperates with the linkage bar 57 to drive the limiting shaft 56 to rotate around its middle, thereby adjusting the scraping angle of the arc-shaped member 52.

[0057] A limiting slider 59 is fixed on the side of the sliding plate 51 facing the collection box 201, and a limiting groove 510 is opened on the side of the collection box 201 facing the sliding plate 51. The limiting slider 59 is slidably connected inside the limiting groove 510 to limit the sliding plate 51, thereby maintaining the stability of the sliding plate 51 when sliding.

[0058] When the oil drain head 33 slides horizontally, the supporting shaft can drive the sliding plate 51 to slide along the extension direction of the limiting slide groove 510. After the sliding plate 51 slides from the right side of the collecting box 201 to the left side thereof, the push bar 58 on the left side of the collecting box 201 drives the limiting rotating shaft 56 to rotate around its middle through the linkage bar 57. At this time, the arc-shaped member 52 rotates to the left, so that the connecting port 53 on the right side of the arc-shaped member 52 corresponds to the working area of ​​the upper transmission roller 116. When the sliding plate 51 slides from the left side of the collecting box 201 to the right side, the arc-shaped member 52 can scrape the stamping oil on the surface of the upper transmission roller 116. The stamping oil containing iron filings can enter the connecting port 53 located on the left side of the arc-shaped member 52 and be filtered by the second filter screen 54. The filtered stamping oil is discharged to the surface of the working area of ​​the upper transmission roller 116 through the oil discharge port 55, so that the upper transmission roller 116 can evenly apply the stamping oil to the surface of the material belt. When the sliding plate 51 slides from the left side of the collecting box 201 to the right side thereof, the push bar 58 on the right side of the collecting box 201 drives the limiting shaft 56 to rotate around its middle through the linkage bar 57. At this time, the arc-shaped member 52 rotates right to adjust the angle for reset, thereby repeating the above operation.

[0059] Through the cleaning component 50, the stamping oil and attached iron filings impurities in the working area of ​​the upper transmission roller 116 can be cleaned, and the scraped stamping oil can be filtered, and the filtered stamping oil is discharged to the working area of ​​the upper transmission roller 116 again, thereby maintaining the uniformity of the stamping oil applied to the material strip by the upper transmission roller 116.

[0062] Step three: The tip of the mounting seat 203 scrapes the stamping oil and iron filings on the surface of the non-working area of ​​the upper transmission roller 116, and the first filter screen 212 filters the scraped and dropped stamping oil. The filtered stamping oil flows into the interior of the collecting box 201 and is discharged to the surface of the material belt through the oil spreading assembly 30.

[0063] Step 4: The cleaning component 50 scrapes and cleans the iron filings and other attachments on the working area surface of the upper transmission roller 116.

[0064] Step 5: The material strip coated with stamping oil is transferred to the stamping position of the stamping machine 10 by the upper transmission roller 116 and is stamped and bent into the shielding cover 13 by the die.
