Description

Technical Field

[0001] The invention relates to the field of stamping devices, in particular to a stamping device and a stamping method for producing optical lens gaskets. Background Art

[0002] With the development of society and the continuous progress of mankind, various advanced equipment has been continuously developed. Among them, stamping is a forming processing method that relies on presses and dies to apply external forces to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Stamping and forging are both plastic processing, collectively known as forging. The production and processing of optical lens washers cannot be separated from the application of stamping devices.

[0003] Regarding the use of stamping devices in the production of gaskets, the stamping mechanism stamps the fixed gaskets. During the process, the stamping plate that contacts the gasket needs to be fixed on the stamping mechanism. However, during the continuous stamping process, ordinary mounting parts will become loose due to continuous setbacks, making it difficult for the stamping mechanism and the stamping plate to maintain a relatively static state. At the same time, after each stamping action is completed, the position of the stamping plate needs to be adjusted manually for the next stamping.

[0004] When the stamping plate shakes due to continuous stamping, the downward pressing action makes it difficult for the stamping plate to act accurately on the gasket. At the same time, there will be deviations in the position adjustment of the stamping plate after each stamping, which greatly reduces the accuracy of the gasket processing process. In turn, a large amount of waste is generated during the stamping process during gasket production, which brings great trouble to people. Summary of the invention

[0005] In order to overcome the shortcomings of the existing technical solutions, the present invention provides a stamping device and a stamping method for producing optical lens gaskets, which can effectively solve the problem raised in the background technology that shaking and offset phenomena occurring during the stamping process affect the gasket production accuracy.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A punching device for producing optical lens gaskets, comprising an operating table and a support column fixedly mounted on the side of the operating table, a cylinder as a punching power source is fixedly mounted on the top of the support column, a sliding table is fixedly mounted on the output end of the cylinder, and a through hole for sleeved on the support column is provided on one side of the sliding table, and the sliding table reciprocates up and down along the support column under the drive of the cylinder;

[0008] A clamping mechanism is installed at the bottom of the sliding table through multiple reset mechanisms. A clamping area is arranged on the operating table at a position corresponding to the clamping mechanism. Multiple loading areas are fixedly installed outside the clamping area, and a stamping ring is movably installed in each loading area.

[0009] As a preferred technical solution of the present invention, the reset mechanism includes: the reset mechanism includes a mounting top plate, a top corner of the mounting top plate is provided with a sliding rod for guidance, and one end of several of the sliding rods passes through the top of the mounting top plate and extends to the outside thereof, and a sliding guide sleeve is provided on the surface of the sliding rod.

[0010] As a preferred technical solution of the present invention, a spring tube is sleeved axially on the surface of the sliding rod on one side of the sliding guide sleeve; and

[0011] The top end of the spring tube contacts the top end of the sliding guide sleeve.

[0012] As a preferred technical solution of the present invention, a bottom plate for moving up and down is provided at one end of the sliding rod away from the mounting top plate.

[0013] As a preferred technical solution of the present invention, the clamping mechanism includes a supporting plate, a chuck is axially fixed to the top of the supporting plate, and three groups of trapezoidal limiting grooves are radially formed on the top of the chuck.

[0014] As a preferred technical solution of the present invention, a connecting rod is provided at the center of the chuck, and a stamping plate is fixed to the bottom end of the connecting rod; and,

[0015] One end of the connecting rod extends to the outside of the reset mechanism; when the stamping plate moves to the top of the clamping area, the stamping ring at the loading area is continuously pressurized to complete the stamping action.

[0016] As a preferred technical solution of the present invention, a clamping block is slidably embedded in the inner part of the three groups of trapezoidal limiting grooves; and,

[0017] One end of the clamping block extends to the outside of the trapezoidal limiting groove, and the width of the trapezoidal limiting groove decreases as the clamping plate moves away from its center position; wherein,

[0018] The clamping block with a constant width continuously slides toward the end of the trapezoidal limiting groove away from the center of the chuck when the inner diameter increases, thereby increasing the squeezing force between the clamping block and the inner side wall of the trapezoidal limiting groove to avoid shaking during movement.

[0019] As a preferred technical solution of the present invention, one end of the clamping block outside the trapezoidal limiting groove is evenly provided with inclined convex strips, the inclined convex strips are in contact with the connecting rod, and the friction force generated between the adjacent inclined convex strips and the connecting rod is along the setting direction of the inclined convex strips.

[0020] In addition, the present invention also provides a punching method for producing an optical lens gasket, comprising the following steps:

[0021] Step 100: Place the component to be punched in the loading area, and the cylinder drives the sliding table to press down along the support column until the punching plate and the component to be punched complete the punching action;

[0022] Step 200: When the cylinder drives the sliding platform to press down along the support column, the sliding guide sleeve compresses and deforms the spring tube along the slide rod to keep the moving track of the stamping plate always parallel to the slide rod;

[0023] Step 300, when the stamping plate contacts the loading area and generates extrusion force, the connecting rod is pushed upward, and the upward thrust is offset by increasing friction with the inclined convex strip. At the same time, the trapezoidal limit groove and the clamping block increase the extrusion force on the surface of the connecting rod, so that the extrusion force increases continuously during the continuous stamping process.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention installs the connecting rod by means of a clamping mechanism, so that the stamping plate fixed at the bottom end thereof can continuously increase the tightness of the connecting rod installation during the continuous stamping action, and at the same time, after the stamping action is completed, the stamping plate is returned to its original position under the action of the resetting mechanism, thereby solving the problems of the stamping plate shaking and manual adjustment of the position of the stamping plate, avoiding shaking and offset when such devices are used, and enhancing production accuracy.

[0036] The following will be combined with the drawings in the embodiments of 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.

[0037] like Figures 1 to 4 As shown, the present invention provides a punching device for producing optical lens gaskets, comprising an operating table 1 and a support column 2 fixedly mounted on the side of the operating table 1, a cylinder 4 as a punching power source is fixedly mounted on the top of the support column 2, a sliding table 5 is fixedly mounted on the output end of the cylinder 4, and a through hole for being sleeved on the support column 2 is provided on one side of the sliding table 5, and the sliding table 5 performs a reciprocating motion up and down along the support column 2 under the drive of the cylinder 4;

[0038] A clamping mechanism 7 is installed at the bottom of the sliding table 5 through multiple reset mechanisms 6. A clamping area 11 is set at the position corresponding to the clamping mechanism 7 on the operating table 1. Multiple loading areas 12 are fixedly installed outside the clamping area 11, and a stamping ring 13 is movably installed in each loading area 12.

[0039] Specifically, when in use, the device is first connected to an external power supply and a control system. When the cylinder 4 pushes the sliding table 5 to move along the support column 2, the reset mechanism 6 maintains the same movement state with it. The extrusion force generated after stamping will drive the clamping mechanism 7 to rebound to its original state through the reset mechanism 6. At the same time, the clamping mechanism 7 will continuously tighten the stamping plate 76, thereby solving the shaking and offset problems that occur when such devices are used and enhancing production accuracy.

[0040] like Figure 1 and Figure 2As shown, the reset mechanism 6 includes a mounting top plate 61, a top corner of the mounting top plate 61 is provided with a slide rod 63 for guiding, and one end of a plurality of slide rods 63 passes through the top of the mounting top plate 61 and extends to the outside thereof, and a sliding guide sleeve 64 is sleeved on the surface of the slide rod 63; a spring cylinder 65 is sleeved axially on the surface of the slide rod 63 on one side of the sliding guide sleeve 64; and the top end of the spring cylinder 65 is in contact with the top end of the sliding guide sleeve 64; a bottom plate 62 for moving up and down is provided at one end of the slide rod 63 away from the mounting top plate 61.

[0041] During the stamping action, the mounting top plate 61 moves downward to compress the spring tube 65 on the surface of the sliding rod 63. After the stamping is completed, the spring tube 65 rebounds through the mounting top plate 61 to push the sliding table 5 to its original position. Since the clamping mechanism 7 is installed on the bottom plate 62, the clamping mechanism 7 is also returned to its original position at this time.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, the clamping mechanism 7 includes a support plate 71, a clamping plate 72 is fixed axially at the top of the support plate 71, and three groups of trapezoidal limiting grooves 73 are radially provided at the top of the clamping plate 72; a connecting rod 75 is provided at the center of the clamping plate 72, and a stamping plate 76 is fixed at the bottom of the connecting rod 75; and one end of the connecting rod 75 extends to the outside of the reset mechanism 6; when the stamping plate 76 moves to the top of the clamping area 11, the stamping ring 13 at the position of the loading area 12 is continuously pressurized to complete the stamping action; a clamping block 74 is slidably embedded in the inner part of the three groups of trapezoidal limiting grooves 73; and one end of the clamping block 74 The end extends to the outside of the trapezoidal limiting groove 73, and the width of the trapezoidal limiting groove 73 decreases as the chuck 72 moves away from its center position; wherein, the clamping block 74 with a constant width continuously slides toward the end of the trapezoidal limiting groove 73 away from the center position of the chuck 72 when the inner diameter becomes larger, thereby increasing the squeezing force between the clamping block 74 and the inner side wall of the trapezoidal limiting groove 73 to avoid shaking during movement; one end of the clamping block 74 outside the trapezoidal limiting groove 73 is evenly provided with inclined ridges 77, the inclined ridges 77 are in contact with the connecting rod 75, and the friction force generated between the adjacent inclined ridges 77 and the connecting rod 75 is along the setting direction of the inclined ridges 77.

[0043] Specifically, the connecting rod 75 is placed at the center position of the chuck 72. At this time, the outer wall of the connecting rod 75 contacts one end of the clamp block 74 to push it to slide along the trapezoidal limiting groove 73. Since the width of the trapezoidal limiting groove 73 decreases as the chuck 72 moves away from its center position, the mutual squeezing force is continuously increasing. At the same time, the inclined convex strip 77 increases the friction between the outer wall of the connecting rod 75 and one end of the clamp block 74, thereby preventing the stamping plate 76 from shaking and deviating from the gasket.

[0044] like Figure 5 As shown, the present invention also provides a punching method for producing an optical lens gasket, comprising the following steps:

[0045] Step 100: Place the component to be punched in the loading area, and the cylinder drives the sliding table to press down along the support column until the punching plate and the component to be punched complete the punching action;

[0046] Step 200: When the cylinder drives the sliding platform to press down along the support column, the sliding guide sleeve compresses and deforms the spring tube along the slide rod to keep the moving track of the stamping plate always parallel to the slide rod;

[0047] Step 300, when the stamping plate contacts the loading area and generates extrusion force, the connecting rod is pushed upward, and the upward thrust is offset by increasing friction with the inclined convex strip. At the same time, the trapezoidal limit groove and the clamping block increase the extrusion force on the surface of the connecting rod, so that the extrusion force increases continuously during the continuous stamping process.

[0048] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
