Description

Technical Field

[0001] This utility model relates to the field of optical glass processing, and in particular to an optical glass forging and pressing equipment. Background Technology

[0002] Forging is a general term encompassing forging and stamping. It is a forming process that uses hammers, anvils, punches, or dies from forging machinery to apply pressure to a blank, causing plastic deformation to obtain a part of the desired shape and size. In pressing circular optical glass workpieces, the raw material is softened and poured into a forging die, then hot-pressed to form the desired glass workpiece. In forging, the blank undergoes significant overall plastic deformation, primarily shaping itself by changing the spatial position of its various parts. There is no large-scale plastic flow within the blank, making it extremely unstable, especially when gripping and moving the glass workpiece.

[0003] In existing glass forging processes, material handling is usually done manually. Due to the high temperature of the glass, manual handling is labor-intensive and poses certain safety hazards. Existing glass mold forging positioning devices generally use simple clamps to hold the glass. When clamping the glass workpiece, it is difficult to achieve a stable grip. If the applied external force is too large, it is easy to squeeze and deform the rounded corners. If the applied external force is too small, the glass is easy to slip and fall, affecting the processing quality and pass rate of the glass workpiece. Therefore, there is an urgent need for a glass forging equipment that can conveniently position the glass. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an optical glass forging device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses an optical glass forging device, including a base. A lower forging assembly is provided on the upper end surface of the base. Several first columns are vertically fixed at the upper left and right ends of the base. An upper connecting plate is fixedly connected to the top of the first columns. An upper forging assembly is connected to the middle of the upper connecting plate. Several second columns are vertically fixed at the upper left and right ends of the upper forging assembly. A cylinder fixing plate is connected to the top of the second columns. A lower pressing cylinder is fixedly connected to the upper end of the cylinder fixing plate. A slide rail is fixedly connected to one side of the lower forging assembly. A rotatable stop is provided above the slide rail.

[0007] As a preferred embodiment of this utility model, the lower forging assembly includes a mold base plate. A circular forging groove for accommodating glass to be forged is formed in the center of the mold base plate.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] like Figure 1-4As shown, this utility model provides an optical glass forging device, including a base 1. A lower forging assembly 2 is fixedly connected to the upper end of the base 1 by bolts. Several first columns 3 are vertically fixed at the left and right ends of the upper part of the base 1. Preferably, the number of first columns 3 is set to 4 and they are symmetrically arranged. An upper connecting plate 4 is fixedly connected to the top of the first columns 3. An upper forging assembly 5 is connected to the middle of the upper connecting plate 4. Four second columns 6 are vertically fixed at the left and right ends of the upper forging assembly 5. A cylinder fixing plate 7 is connected to the top of the second columns 6. A lower pressing cylinder 8 is fixedly connected to the upper end of the cylinder fixing plate 7. A slide rail 9 is fixedly connected to one side of the lower forging assembly 2. A rotatable stop block 10 is provided above the slide rail 9. In this embodiment, the lower pressing cylinder 8 is fixedly connected to the cylinder fixing 7 by four vertically arranged fixed round rods. This optical glass forging device also includes a foot switch (not shown) for controlling the action of the lower pressing cylinder.

[0026] The method of using this utility model is as follows:

[0027] 1. The softened circular glass slides down through the inclined slide rail 9 and enters the mold base plate 11. After being blocked by the directional rail 31, it falls into the forging groove 12. The lower surface of the glass contacts the upper surface of the forging mold 13 in the forging groove, thus completing the positioning of the glass.

[0028] 2. Press the foot switch to control the pressing cylinder 8. The pressing cylinder 8 drives the vertical push rod 23 to move downward. The vertical push rod 23 then pushes the piston rod 22 to move downward. The piston rod 22 then drives the forging head 21 to press down on the surface of the glass. After a certain period of pressure, the forging is completed.

[0029] 3. After forging is completed, the pressing cylinder 8 rises automatically. At the same time, the lifting cylinder 18 starts to move, driving the lifting column 17 to move upward along the lifting groove 16. The lifting column 17 drives the forging die 13 to move upward a certain distance, pushing out the forged glass. Then, the forged glass is manually removed from the mold base plate 11 to complete the entire forging process.

[0030] Furthermore, the lower forging assembly 2 includes a mold base plate 11. A circular forging groove 12 for accommodating the glass to be forged is provided at the center of the mold base plate 11. In this example, the recessed forging groove design makes it less likely for fragments to be ejected during the forging of softened glass, thus improving the safety of the forging process. A cylindrical forging die 13 is fitted onto the inner wall of the forging groove 12. The upper surface of the forging die 13 contacts the lower surface of the glass to be forged, serving to shape the lower surface of the glass block. The outer wall of the forging groove 12 is covered with a heat insulation pad 14. A fixed base 15 is connected to the bottom end of the forging groove 12. A lifting groove 16 is provided at the center of the fixed base 15. A cylindrical lifting column 17 is fitted onto the inner wall of the lifting groove 16. A lifting cylinder 18 is connected to the bottom end of the lifting column 17 and is fixed below the base 1.

[0031] Furthermore, the heat insulation pad 14 has a through hole in the center that matches the outer circle of the forging groove 12, which is used to limit the forging groove 12 and isolate the heat generated on the forging groove 12. The lower end face of the heat insulation pad 14 is fixedly connected to the upper end face of the fixed base 15 by bolts. The upper end face of the heat insulation pad 14 is in contact with the lower end face of the mold base plate 11, which is used to support and buffer the mold base plate 11. When the glass falls into the forging groove 12, the heat insulation pad 14 plays a buffering and heat insulation function, which improves the safety of the softened glass positioning and is very convenient.

[0032] Furthermore, the upper forging assembly 5 includes a vertically downward-mounted forging head 21, which is coaxially arranged with the lower forging groove 12. After being pressed down, the forging head 21 contacts the upper surface of the glass block for forming the upper surface of the glass. A piston rod 22 is coaxially arranged with the forging head 21, which can drive the forging head 21 to move up and down in the vertical direction. The piston rod 22 includes a movable piston and a cylinder, which can buffer the impact force when pressed down, improving the safety of forging. A vertical push rod 23 is fixedly connected to the top of the piston rod 22. The top of the vertical push rod 23 is fixedly connected to the movable end of the pressing cylinder 8. A guide shaft support 24 is slidably connected to the outer surface of the vertical push rod 23. The guide shaft support 24 is fixedly connected to the center of the upper connecting plate 4. When the pressing cylinder 8 moves forward and backward, the forging head 21 can be indirectly pushed to move through the vertical push rod 23 and the piston rod 22.

[0033] Furthermore, the upper surface of the mold base plate 11 is provided with a directional track 31 for guiding the sliding of the glass block. Preferably, the directional track 31 has three blocking edges that surround the forging groove 12, serving as positioning and guiding edges when the glass enters the forging groove 12, thereby allowing the softened glass to accurately fall into the forging groove 12. The slide rail 9 is composed of an inclined track and a horizontal track overlapping each other. The lower end of the horizontal track of the slide rail 9 is fixed to the upper part of the mold base plate 11 by two vertically arranged cylindrical rods. The bottom of the inclined track of the slide rail 9 is connected to the end of the directional track 31, so that when the glass block slides down from the slide rail 9, it can easily enter the directional track 31. In this way, the glass is effectively limited during the automatic sliding process, and the positioning safety of the softened glass is improved.

[0034] Furthermore, the stop 10 is rotatably connected to a crossbar 41, and a torsion spring is provided between the stop 10 and the crossbar 41 to limit the rotation of the stop 10 within a small angle. When the glass block passes through the slide rail 9, the stop 10 limits the upper surface of the glass block so that the glass block can pass through the slide rail 9 quickly and smoothly. Two symmetrically arranged side fixing plates 42 are fixedly connected to both sides of the crossbar 41, and the two side fixing plates 42 are fixed to both sides of the upper connecting plate 4 by bolts. The glass is effectively limited during the automatic sliding process, and the safety is improved.

[0035] Furthermore, the heat insulation pad 14 is made of high-temperature resistant glass fiber reinforced composite material, which can effectively prevent the heat from the high-temperature glass from being transferred to the base 1, thus preventing safety issues such as burns.

[0036] This invention relates to an optical glass forging equipment, which achieves efficient positioning in optical glass forging and improves the safety and production efficiency of forging.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
