Description
Technical Field
[0001] This utility model relates to the field of graphite composite gasket production technology, and in particular to a punching and cutting equipment for graphite composite gasket production. Background Technology
[0002] Graphite composite gaskets (also known as flexible graphite metal reinforced composite gaskets) are made by composite rolling of punched metal core plates and flexible graphite particles. They combine the strength of metal with the temperature resistance and media resistance of graphite and are widely used in high-end flange sealing applications in petrochemical, power and other industries. At present, these gaskets are usually made from graphite composite reinforced rolls as raw materials and cut into shape by punching equipment.
[0003] However, existing punching equipment generally adopts the "single punch - manual material discharge" mode: after the roll material is positioned, the crank slider mechanism drives the die to complete a single punching, and then the machine needs to be stopped or the speed reduced. The operator then manually removes the gaskets embedded in the waste frame one by one, and then restarts the machine to enter the next cycle.
[0004] Although this method has a simple structure, manual material feeding is inefficient and labor-intensive. It is easy for material to accumulate due to untimely removal of the gaskets, which limits the speed of the whole machine. At the same time, manual contact with the edge of the gasket can easily introduce secondary pollution or damage, affecting the sealing performance and making it difficult to meet the needs of efficient, continuous and clean production. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a graphite composite gasket production punching equipment to solve the problems of low efficiency, high labor intensity, easy contamination of gaskets and restriction of continuous high-speed production caused by manual material feeding.
[0006] This utility model provides a punching and cutting equipment for producing graphite composite gaskets, including a workbench, a support frame fixedly connected to the lower end of the workbench, an installation groove formed on the upper surface of the workbench, clearance grooves formed on both the front and rear end surfaces of the workbench, an installation frame fixedly connected to the middle of the upper end of the support frame, a discharge plate fixedly connected to the upper right side of the support frame, the discharge plate being located directly below the installation groove, and guide rollers rotatably connected to the upper ends of both the left and right sides of the workbench; it also includes:
[0007] A punching mechanism is mounted on the upper end of a workbench and punches graphite composite rolls.
[0008] The unloading mechanism is installed on the upper part of the workbench and located to the right of the punching mechanism. The unloading mechanism is used to separate the punched and formed gasket from the graphite composite roll.
[0009] A drive mechanism, which is installed inside the mounting frame, is used to provide power to both the stamping mechanism and the unloading mechanism.
[0010] Preferably, the punching mechanism includes a drive shaft, which is rotatably connected to the mounting frame via a bearing seat. Rotary disks are symmetrically fixedly connected to the front and rear ends of the drive shaft. A connecting rod is rotatably connected to the eccentric position of the rotating disk via a shaft pin. The connecting rod passes through a clearance groove. A fixing plate is hinged to the end of the connecting rod away from the rotating disk. A die is fixedly connected to the lower end of the fixing plate. First guide rods are fixedly connected to the four corners of the lower end of the fixing plate. The lower ends of the first guide rods pass through the worktable and are slidably connected to it.
[0011] Preferably, the die-cutting mold is provided in two sets, the two sets of die-cutting molds are arranged at equal intervals and are located in the left and right halves of the fixed plate respectively, and the left and right sets of die-cutting molds are arranged in an alternating manner.
[0012] Preferably, the unloading mechanism includes a support plate, a pair of which are fixedly connected inside the mounting groove. The front and rear ends of the support plate extend through the front and rear ends of the worktable. The front and rear ends of the support plate are threadedly connected to a second guide rod. A fixing frame is slidably connected to the side wall between the second guide rods on the same side. A pair of fixing frames are provided. The lower ends of the pair of fixing frames are fixedly connected to top rods at equal intervals. The front and rear interiors of the fixing frames are slidably connected to fixing rods. The left end of the fixing rod is fixedly connected to the left end of the fixing plate. The upper end of the fixing frame is bolted to a bolt, and the lower end of the bolt abuts against the upper end of the fixing rod.
[0013] Preferably, the upper surfaces of the pair of support plates are provided with unloading holes at equal intervals, and the unloading holes in the two sets of support plates are arranged in an alternating manner. The push rod is located directly above the corresponding unloading hole. The unloading hole located on the left side of the worktable corresponds to the die on the left side of the fixed plate, and the unloading hole located on the right side of the worktable corresponds to the die on the right side of the fixed plate.
[0014] Preferably, the drive mechanism includes a first bevel gear, which is fixedly connected to the side wall of the drive shaft. A second bevel gear meshes with the side wall of the first bevel gear. A motor is fixedly connected inside the mounting frame, and the output shaft end of the motor is fixedly connected to the left end of the second bevel gear.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model uses the same motor to synchronously drive the punching mechanism and the unloading mechanism via the first bevel gear and the second bevel gear. While the die is punching downwards, the fixed plate drives the fixed rod and the fixed frame to move downwards synchronously. The push rod enters the unloading hole with the fixed frame. At the moment of the die's return stroke, the gasket embedded in the roll material is pushed out, realizing the integrated continuous action of "punching-unloading". There is no need to stop the machine or manually remove the sheet, which solves the problems of low efficiency and high labor intensity of manual material unloading.
[0017] 2. This utility model uses two rows of staggered die-cutting molds matched with corresponding staggered unloading holes to complete the punching and synchronous ejection of multiple gaskets in one stroke. The gaskets slide continuously down the unloading plate for collection, avoiding secondary pollution and damage caused by manual contact. At the same time, the first guide rod and the second guide rod provide guidance throughout the entire process, ensuring the repeatability and positioning accuracy of the cutter head and the ejector rod. The finished product has neat edges and stable sealing performance, meeting the clean sealing requirements of high-end flanges. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5 As shown, this utility model has the following three specific embodiments.
[0027] Example 1
[0028] A punching and cutting device for producing graphite composite gaskets includes a workbench 1, a support frame 2 fixedly connected to the lower end of the workbench 1, an installation groove 13 formed on the upper surface of the workbench 1, clearance grooves 11 formed on both the front and rear end surfaces of the workbench 1, an installation frame 21 fixedly connected to the middle of the upper end of the support frame 2, a discharge plate 6 fixedly connected to the upper right side of the support frame 2, the discharge plate 6 being located directly below the installation groove 13, and guide rollers 12 rotatably connected to the upper ends of both the left and right sides of the workbench 1; it also includes:
[0029] Punching mechanism 3 is installed on the upper end of workbench 1 and punches graphite composite rolls.
[0030] The unloading mechanism 5 is installed on the upper end of the workbench 1 and is located to the right of the punching mechanism 3. The unloading mechanism 5 is used to separate the punched and formed gasket from the graphite composite roll.
[0031] The drive mechanism 4 is installed inside the mounting frame 21 and is used to provide power to both the stamping mechanism and the unloading mechanism 5.
[0032] In this embodiment, as Figure 1 As shown, the workbench 1 is horizontally fixed by the support frame 2. The mounting groove 13 and the clearance groove 11 provide space for punching and unloading operations. The driving mechanism 4 drives the punching mechanism 3 to operate, so that staggered punching is completed on the graphite composite roll. At the same time, the punching mechanism 3 drives the unloading mechanism 5 to operate, thereby pushing the punched pad out of the roll. The pad slides down continuously through the unloading plate 6 for collection. The roll is continuously fed by the guide roller 12, realizing the integrated continuous operation of punching and unloading under the drive of a single motor 43.
[0033] Example 2
[0034] The difference from Embodiment 1 is that this embodiment discloses a punching mechanism 3 and a driving mechanism 4;
[0035] The punching mechanism 3 includes a drive shaft 31, which is rotatably connected to the mounting frame 21 via a bearing seat. The drive shaft 31 is symmetrically fixed to a rotating disk 32 at its front and rear ends. The eccentric position of the rotating disk 32 is rotatably connected to a connecting rod 33 via a shaft pin. The connecting rod 33 passes through the clearance groove 11. A fixing plate 34 is hinged to the end of the connecting rod 33 away from the rotating disk 32. A die 35 is fixedly connected to the lower end of the fixing plate 34. A first guide rod 36 is fixedly connected to each of the four corners of the lower end of the fixing plate 34. The lower end of the first guide rod 36 passes through the worktable 1 and is slidably connected to it.
[0036] Two sets of die-cutting molds 35 are provided. The two sets of die-cutting molds 35 are arranged at equal intervals and are located in the left and right halves of the fixed plate 34 respectively. The two sets of die-cutting molds 35 are arranged in an alternating manner.
[0037] The drive mechanism 4 includes a first bevel gear 41, which is fixedly connected to the side wall of the drive shaft 31. A second bevel gear 42 meshes with the side wall of the first bevel gear 41. A motor 43 is fixedly connected inside the mounting frame 21. The output shaft end of the motor 43 is fixedly connected to the left end of the second bevel gear 42.
[0038] In this embodiment, as Figures 2-3 As shown, the motor 43 drives the first bevel gear 41 through the second bevel gear 42 to rotate the drive shaft 31. The front and rear rotating disks 32 rotate synchronously and push the connecting rod 33 with the help of the eccentric pin. The connecting rod 33 passes through the clearance groove 11 and is hinged to the fixed plate 34. The fixed plate 34 only moves vertically under the guidance of the four first guide rods 36. The left and right halves of the lower end of the fixed plate 34 are each provided with a row of staggered die 35. When the fixed plate 34 moves down, the two rows of die 35 punch out the staggered pads on the graphite composite roll at the same time. When returning, the die 35 are lifted away from the roll material, and the guide roller 12 continues to feed the material, realizing high-speed staggered punching under the drive of a single motor 43.
[0039] Example 3
[0040] The difference from Embodiment 2 is that this embodiment discloses an unloading mechanism 5;
[0041] The unloading mechanism 5 includes a support plate 51. A pair of support plates 51 are provided and fixedly connected inside the mounting groove 13. The front and rear ends of the support plate 51 pass through the front and rear ends of the workbench 1. The front and rear ends of the support plate 51 are connected to the second guide rod 52 by threads. A fixed frame 53 is slidably connected to the side wall between the second guide rods 52 on the same side. A pair of fixed frames 53 are provided. The lower ends of the pair of fixed frames 53 are fixedly connected to the top rods 531 at equal intervals. The front and rear interiors of the fixed frame 53 are slidably connected to the fixed rods 54. The left end of the fixed rod 54 is fixedly connected to the left end of the fixed plate 34. The upper end of the fixed frame 53 is connected to the bolt 55 by bolt 55. The lower end of the bolt 55 abuts against the upper end of the fixed rod 54.
[0042] A pair of support plates 51 have unloading holes 511 equidistantly opened on their upper surfaces. The unloading holes 511 in the two sets of support plates 51 are arranged in an alternating manner. The push rod 531 is located directly above the corresponding unloading hole 511. The unloading hole 511 located on the left side of the worktable 1 corresponds to the die 35 on the left side of the fixed plate 34, and the unloading hole 511 located on the right side of the worktable 1 corresponds to the die 35 on the right side of the fixed plate 34.
[0043] In this embodiment, as Figures 4-5As shown, a pair of support plates 51 are fixed in the mounting groove 13 and span the front and rear of the workbench 1. The plates have staggered unloading holes 511 that are offset from the die 35. When the fixed plate 34 is raised and lowered, it drives the fixed rod 54 to move synchronously. The fixed rod 54 presses the fixed frame 53 with bolts 55, so that the fixed frame 53 slides vertically along the second guide rod 52. The top rod 531 at the lower end of the fixed frame 53 is accurately inserted into the corresponding unloading hole 511, pushing the punched gasket out of the graphite composite roll. The gasket then falls onto the unloading plate 6 to complete the automatic separation. The height of the fixed frame 53 can be adjusted by loosening the bolts 55 to adapt to rolls of different thicknesses and achieve precise linkage between punching and unloading actions.
[0044] The working principle of this utility model is as follows:
[0045] After the motor 43 starts, it drives the first bevel gear 41 and the drive shaft 31 to rotate through the second bevel gear 42. The rotating disks 32 at both ends of the drive shaft 31 rotate synchronously. The eccentric pin drives the connecting rod 33 to move up and down. The connecting rod 33 pushes the fixed plate 34 to move vertically up and down along the first guide rod 36 through the clearance groove 11. When the fixed plate 34 moves down, the two rows of staggered die 35 at its lower end punch out correspondingly arranged shims on the graphite composite roll. At the same time, the fixed plate 34 drives the fixed rod 54 to move down. The fixed rod 54 is connected by bolts. 55 presses the fixing frame 53, causing the fixing frame 53 to slide down synchronously along the second guide rod 52. The push rod 531 is accurately inserted into the corresponding unloading hole 511 of the support plate 51, pushing the punched gasket out of the roll. When the fixing plate 34 moves upward, the die 35 leaves the roll, and the push rod 531 is pulled out. The guide roller 12 continues to feed the material. Punching and unloading are completed in the same reciprocating cycle. The gasket slides down continuously through the unloading plate 6 for collection, realizing high-speed, continuous, and automatic punching and unloading integrated operation driven by a single motor 43.
[0046] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
