Description

Technical Field

[0001] The invention relates to the technical field of a stamping die set capable of being guided and positioned, in particular to a stamping die set for a cylinder gasket of an automobile with a guiding support. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. When producing cylinder gaskets for multi-cylinder engines, it is only necessary to place a metal sheet between the upper and lower dies and punch out the corresponding number of cylinder holes on the sheet.

[0003] In the related art, a Chinese patent with announcement number CN222113280U discloses a self-lubricating stamping die, the key points of its technical solution are: including a workbench and a punching machine body, and also including guide columns and buffer mechanisms located on both sides of the upper surface of the workbench, the front end of the upper surface of the workbench is fixedly installed with a lower die, the front end surface of the punching machine body is connected with a connecting plate, the lower end of the connecting plate is provided with a mounting plate, the lower end surface of the mounting plate is fixedly installed with an upper die, the two sides of the mounting plate are fixedly connected with guide blocks, and the side surface of the guide column is provided with a guide groove. The problem of poor stability of the existing stamping die is solved. When the mounting plate drives the upper die to move up and down, the guide blocks on both sides of the mounting plate slide synchronously with it inside the guide groove, thereby achieving a limiting effect, which can effectively prevent the upper die from moving up and down frequently and causing offset.

[0004] However, although the above patent can use the extrusion block to squeeze out the lubricating oil in the rubber bag during the stamping process to solve the jamming phenomenon caused by the frequent friction between the guide groove inside the guide column and the guide block, it does not deal with the subsequent lubrication of the lubricating oil. If the lubricating oil is not recovered in time after use, it will not only cause waste and increase material costs, but also if the lubricating oil flows to the surface of the automobile cylinder gasket, it will cause the surface of the automobile cylinder gasket to absorb dust, affecting the tightness of the automobile cylinder gasket when it fits with other engine parts.

DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the process of punching a metal sheet out of a cylinder hole to obtain a cylinder gasket for an automobile, in order to ensure the stability of the stamping process and to improve the precision of the obtained cylinder gasket product, guide pillars (i.e., the guide mechanism 400 hereinafter) are provided on both sides of the punch (i.e., the stamping part 220 to be described hereinafter) to improve stability.

[0020] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide an automobile cylinder gasket stamping die set with a guide pillar, including a first die frame 110, a second die frame 120 and a base 130 arranged in sequence from high to low, and the four corners of the first die frame 110, the second die frame 120 and the base 130 are fixedly connected with a fixing pillar 140; A stamping mechanism 200 is provided in the middle of the first die frame 110, the second die frame 120 and the base 130. The stamping mechanism 200 at least includes a stamping part 220 slidably connected to the second die frame 120 and a fixed die 230 fixedly connected to the top of the base 130. Clamping mechanisms 300 are provided at the four corners of the top of the fixed die 230. A plurality of guide mechanisms 400 are provided between the stamping part 220 and the fixed die 230. The guide mechanism 400 at least includes a guide column 410. One end of the guide column 410 is fixedly connected to the stamping part 220. One end of the guide column 410 away from the stamping part 220 is slidably connected to the fixed die 230. The guide mechanism 400 also includes a liquid storage cavity 420 for storing lubricating oil provided in the fixed die 230. The stamping mechanism 200 is used to stamp the metal sheet to be stamped, the plurality of clamping mechanisms 300 are used to fix the metal sheet, and the plurality of guide mechanisms 400 are used to maintain the stability of the stamping part 220 during the stamping process; When the stamping part 220 gradually approaches the fixed die 230, the stamping part 220 gradually presses the metal sheet between the multiple clamping mechanisms 300, so that the multiple clamping mechanisms 300 clamp the metal sheet, and the guide column 410 that slides into the liquid storage cavity 420 gradually squeezes out the lubricating oil; When the stamping part 220 gradually moves away from the fixed die 230, the plurality of clamping mechanisms 300 automatically withdraw the stamped automobile cylinder gasket, and the guide column 410 that slides out of the liquid storage cavity 420 gradually absorbs the extruded lubricating oil into the liquid storage cavity 420; The process of the guide column 410 extruding and sucking the lubricating oil can improve the smoothness of the stamping part 220 during the descending and ascending process.

[0021] Working principle: First, start the stamping mechanism 200 so that the stamping part 220 is in a position away from the fixed die 230, and then place the metal sheet to be stamped above the fixed die 230. At this time, the metal sheet is located on the upper part of multiple clamping mechanisms 300, that is, at this time, there is still a certain distance between the metal sheet and the top of the fixed die 230, thus ensuring the convenience of workers in placing the metal sheet.

[0022] Next, the stamping mechanism 200 is started to drive the stamping part 220 to approach the fixed die 230 below it. After the stamping part 220 contacts the metal sheet, the top of the metal sheet is pressed against the top of the fixed die 230 by the stamping part 220. At this time, the metal sheet is located at the bottom of the multiple clamping mechanisms 300, and its side is clamped by the multiple clamping mechanisms 300. Next, the stamping part 220 continues to move downward to complete the mold closing with the fixed die 230, thereby punching out the cylinder hole of the automobile cylinder gasket on the metal sheet.

[0023] When the stamping part 220 approaches the fixed die 230, the guide post 410 gradually slides into the liquid storage chamber 420, and the lubricating oil in the liquid storage chamber 420 is squeezed and moves upward along the surface of the guide post 410 to lubricate the contact part between the guide post 410 and the fixed die 230. When the guide post 410 slides into the liquid storage chamber 420, the resistance of the compressed lubricating oil ensures the smoothness of the stamping part 220 approaching the fixed die 230, thereby ensuring the accuracy of the obtained automobile cylinder gasket.

[0024] After the stamping is completed, the stamping mechanism 200 is started again to drive the stamping part 220 away from the fixed die 230. As the stamping part 220 removes the pressure on the top of the metal sheet, the metal sheet originally located at the bottom of the multiple clamping mechanisms 300 (which has been processed into a car cylinder gasket at this time) is squeezed back to the upper part, making it easier for workers to remove the car cylinder gasket.

[0025] In the process of the stamping part 220 moving away from the fixed mold 230, the guide column 410 gradually slides out of the liquid storage chamber 420, and the guide column 410 slides in the opposite direction in the liquid storage chamber 420, so that the liquid storage chamber 420 generates a negative pressure, and the lubricating oil originally squeezed out of the liquid storage chamber 420 is re-sucked into the liquid storage chamber 420, completing the recovery of the lubricating oil, reducing the waste of the lubricating oil, and preventing the lubricating oil from flowing onto the cylinder gasket of the automobile.

[0026] When stamping a metal sheet into a cylinder gasket for an automobile, the stamped metal fragments are easily stuck in the stamping part 220 or the fixed die 230, affecting the subsequent stamping operation. When cleaning, the stamping mechanism 200 needs to be shut down, which slows down the processing efficiency. Therefore, the traditional stamping mechanism 200 is improved to achieve: after the stamping is completed, the stamped metal fragments are automatically returned.

[0027] like Figure 4-Figure 6 As shown, the stamping mechanism 200 further includes a hydraulic rod 210 , a fixed portion of the hydraulic rod 210 is fixedly connected to the first die frame 110 , and a movable portion of the hydraulic rod 210 is fixedly connected to the stamping part 220 .

[0028] The improvement is that the stamping part 220 includes a movable die 221 , a plurality of punches 222 are provided at the bottom of the movable die 221 , a top block 223 is provided inside each punch 222 , and a punch hole 231 is opened at the top of the fixed die 230 at a position corresponding to each punch 222 .

[0029] That is, when the movable part of the hydraulic rod 210 drives the movable die 221 of the stamping part 220 to approach the punching hole 231, before the punch 222 is inserted into the punching hole 231, the movable die 221 gradually presses the metal sheet against the top of the fixed die 230, and as the punch 222 is inserted into the punching hole 231, the punch 222 gradually punches out a cylinder hole on the metal sheet, thereby obtaining a cylinder gasket for an automobile. The shape of the punched metal fragments should originally be the shape of the punching hole 231, but the top of the metal fragments is squeezed by the top block 223, and the metal fragments will appear to be concave downward, so the size of the top of the metal fragments will become smaller than the size of the punching hole 231, so that they fall downward without being stuck in the punching hole 231, and due to the ejection effect of the top block 223, the metal fragments will not be stuck in the punch 222.

[0030] The existing fixing devices mostly adopt bolt-type fixing connection. Every time a cylinder gasket is processed, workers need to manually fix the metal sheet and remove the cylinder gasket after stamping, which affects the processing efficiency of the cylinder gasket. Therefore, the fixing method of the fixing device is improved, and the automatic clamping and removal of the metal sheet is realized through the relative movement of the stamping part 220 and the fixed die 230.

[0031] exist Figure 7-Figure 9 In the figure, the clamping mechanism 300 also includes a fixed base 310 fixedly connected to the top of the fixed mold 230, and the fixed base 310 is slidably connected to a plurality of slide rods 320 on the side close to the punching hole 231, and the plurality of slide rods 320 are fixedly connected to a clamping block 330 at one end away from the fixed base 310, wherein a spring 340 is sleeved on the periphery of one of the slide rods 320 between the fixed base 310 and the clamping block 330.

[0032] Furthermore, the clamping block 330 includes a flat portion 331 at the upper portion and a convex portion 332 at the lower portion, and the convex portion 332 is located at a side close to the punching hole 231 .

[0033] It should be noted that the worker first places the metal sheet to be stamped between multiple clamping blocks 330. At this time, the metal sheet is located on the flat part 331 of the clamping block 330 under the action of its own gravity. As the punch 222 approaches the fixed mold 230, the metal sheet is pressed between the convex parts 332 of each clamping block 330. At this time, the clamping block 330 pushes the slide rod 320 under the extrusion of the metal sheet, and slides relative to the fixed seat 310, while compressing the spring 340.

[0034] When the punch 222 is away from the punch hole 231 after the stamping is completed, the metal sheet (which has been processed into a cylinder gasket) loses the pressure from the top of the die 221. Since the flat part 331 and the convex part 332 of the clamping block 330 are smoothly connected, the restoring force of each spring 340 will push the clamping block 330 back to its original position, and the cylinder gasket originally located between the convex parts 332 of each clamping block 330 will be squeezed back to the flat part 331. The worker only needs to take away the processed cylinder gasket located on the flat part 331, and then put a piece of metal sheet to be processed, which ensures the continuity of the processing process and improves the efficiency of the cylinder gasket processing.

[0035] Although the prior art alleviates the jamming phenomenon caused by long-term friction between the guide column 410 (i.e., the guide block described in the above background technology) and the connecting groove (i.e., the guide groove in the background technology) by adding lubricating oil, there is no subsequent treatment for the lubricating oil after it completes the lubrication function. If the lubricating oil is not recovered in time after use, it will not only cause waste and increase material costs, but also if the lubricating oil flows to the surface of the automobile cylinder gasket, the surface of the automobile cylinder gasket will absorb dust, affecting the tightness of the automobile cylinder gasket when it fits with other engine components, thereby affecting the yield rate of the automobile cylinder gasket. Therefore, the contact part between the guide column 410 and the connecting groove is improved so that the extruded lubricating oil can be automatically collected after the stamping is completed.

[0036] Next, through Fig.10 and Fig.11 The specific structure of the guide mechanism 400 is disclosed. The guide mechanism 400 also includes a piston cake 430 slidably connected to the liquid storage chamber 420. The piston cake 430 is fixedly connected to the guide column 410. A connecting groove for connecting the inside and outside of the liquid storage chamber 420 is opened at the top of the liquid storage chamber 420. The guide column 410 is slidably connected to the connecting groove. A protective sleeve 440 is provided on the outer periphery of the guide column 410. A plurality of liquid flow grooves 450 are opened on the edges of the guide column 410 and the piston cake 430.

[0037] Moreover, the number of edges of the guide pillar 410 passing through the liquid groove 450 is greater than the number of edges of the piston cake 430 passing through the liquid groove 450 .

[0038] It should be disclosed that when the movable mold 221 approaches the fixed mold 230, the guide column 410 drives the piston cake 430 to slide downward in the liquid storage chamber 420, and the liquid storage chamber 420 generates positive pressure in the space below the piston cake 430. Since the liquid storage chamber 420 contains lubricating oil below the piston cake 430, as the piston cake 430 continues to move downward, the lubricating oil is squeezed through the liquid groove 450 at the edge of the piston cake 430, flows to the upper part of the piston cake 430, and continues to flow along the liquid groove 450 at the edge of the guide column 410, through the connecting groove to the top of the fixed mold 230, and exists inside the protective sleeve 440, thereby lubricating the contact part between the guide column 410 and the connecting groove. In the above process, when the piston cake 430 squeezes the lubricating oil below it, the resistance of squeezing the lubricating oil makes the process of the punch 222 punching the metal sheet downward become smooth, which can prevent the punch 222 from falling too fast and colliding violently with the metal sheet and damaging the punch 222.

[0039] When the movable mold 221 moves away from the fixed mold 230, the guide column 410 drives the piston cake 430 to slide upward in the liquid storage chamber 420, and the liquid storage chamber 420 generates negative pressure in the space below the piston cake 430. The lubricating oil that was originally squeezed above the piston cake 430 and located inside the protective sleeve 440 is re-sucked into the liquid storage chamber 420 (back to the space below the piston cake 430) under the attraction of the negative pressure in the space below the piston cake 430.

[0040] Furthermore, since the number of liquid grooves 450 passing through the edge of the guide column 410 is greater than the number of liquid grooves 450 passing through the edge of the piston cake 430, the amount of lubricating oil that can pass through the piston cake 430 per unit time is reduced, increasing the resistance of the piston cake 430 to move downward in the liquid storage chamber 420, thereby making the process smoother. At the same time, since the radius of the guide column 410 is smaller than the radius of the piston cake 430, the larger number of liquid grooves 450 passing through the edge of the guide column 410 allows the lubricating oil flowing to the upper part of the piston cake 430 to pass through the connecting groove in time and enter the protective sleeve 440 at the top of the fixed mold 230, while giving the movable mold 221 a certain movement resistance, it also ensures the smoothness of its stamping process of the metal sheet.

[0041] In summary, the working principle of the present invention is as follows: First, start the hydraulic rod 210 to make the stamping part 220 away from the fixed die 230, and then place the metal sheet to be stamped above the fixed die 230. At this time, the metal sheet is located on the flat part 331 of the multiple clamping blocks 330, that is, at this time, there is still a certain distance between the metal sheet and the top of the fixed die 230, thus ensuring the convenience of workers in placing the metal sheet.

[0042] Next, when the movable part of the hydraulic rod 210 drives the movable die 221 of the stamping part 220 to approach the punching hole 231, before the punch 222 is inserted into the punching hole 231, the movable die 221 gradually presses the metal sheet against the top of the fixed die 230, and as the punch 222 is inserted into the punching hole 231, the punch 222 gradually punches out a cylinder hole on the metal sheet, thereby obtaining a cylinder gasket for an automobile. The shape of the punched metal fragments should originally be the shape of the punching hole 231, but the top of the metal fragments is squeezed by the top block 223, and the metal fragments will appear to be concave downward, so the size of the top of the metal fragments will become smaller than the size of the punching hole 231, so that they fall downward and will not be stuck in the punching hole 231, and due to the ejection effect of the top block 223, the metal fragments will not be stuck in the punch 222.

[0043] When the movable mold 221 approaches the fixed mold 230, the guide column 410 drives the piston cake 430 to slide downward in the liquid storage chamber 420, and the liquid storage chamber 420 generates positive pressure in the space below the piston cake 430. Since the liquid storage chamber 420 contains lubricating oil below the piston cake 430, as the piston cake 430 continues to move downward, the lubricating oil is squeezed through the liquid groove 450 at the edge of the piston cake 430, flows to the upper part of the piston cake 430, and continues to flow along the liquid groove 450 at the edge of the guide column 410, through the connecting groove to the top of the fixed mold 230, and exists in the inside of the protective sleeve 440 (to prevent the automobile cylinder gasket from absorbing dust due to being contaminated with lubricating oil), thereby lubricating the contact part between the guide column 410 and the connecting groove. In the above process, when the piston cake 430 squeezes the lubricating oil below it, the resistance of squeezing the lubricating oil makes the process of the punch 222 punching the metal sheet downward become smooth, which can prevent the punch 222 from falling too fast and colliding violently with the metal sheet and damaging the punch 222.

[0044] When the movable mold 221 moves away from the fixed mold 230, the guide column 410 drives the piston cake 430 to slide upward in the liquid storage chamber 420, and the liquid storage chamber 420 generates negative pressure in the space below the piston cake 430. The lubricating oil that was originally squeezed above the piston cake 430 and located inside the protective sleeve 440 is re-sucked into the liquid storage chamber 420 under the attraction of the negative pressure in the space below the piston cake 430.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
