Description

Technical Field

[0001] The invention relates to the technical field of glass casting, in particular to a glass casting fixture. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt, which is an amorphous solid with irregular structure. It is widely used in buildings to block wind and transmit light, and is a mixture. There are also colored glass that shows color by mixing certain metal oxides or salts, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called organic glass.

[0003] In the process of glass production, it is necessary to first put the glass raw materials into the crucible, then put the crucible into the furnace to be heated, and then heat the furnace. After the raw materials inside the crucible are melted into glass solution, the crucible is taken out and the solution is poured out, and then the next step is performed. In this process, a clamp is needed to clamp the outer wall of the crucible to help insert or take the crucible. Since the outer diameter of the bottom of the crucible is often equal to the inner diameter of the furnace, and the overall shape of the crucible is cylindrical and has a certain weight, the clamping method of the old clamp is relatively simple and requires high proficiency. After clamping the crucible, it is necessary to master the clamping force and repeatedly move the position to align the bottom of the crucible with the inside of the furnace. The overall operation is relatively troublesome. For this reason, we propose a glass pouring clamp. Summary of the invention

[0004] The object of the present invention is to provide a glass pouring fixture to solve the problems raised in the above background technology.

[0007] Preferably, a fixed shaft 1 is provided on one side of the retaining plate, a roller is provided on the outside of the fixed shaft 1, and a torsion spring is provided between the fixed shaft 2 and the connecting block. Under normal conditions, the elastic force of the torsion spring can rotate the connecting column to be parallel to the furnace.

[0009] Preferably, a clamping assembly is provided inside the support rod for cooperating with the clamping block to clamp the outer wall of the crucible, the clamping assembly includes a slide plate three located at the top of the support rod, a sliding column is provided on one side of the slide plate three, a clamping block is provided at one end of the sliding column, the clamping block includes a clamping portion, a sliding groove for sliding the sliding column is provided inside the support rod, and a handle is provided on one side of the slide plate three.

[0010] Preferably, a limiting assembly for limiting the sliding of the sliding column is provided inside the slide groove, and the limiting assembly includes a limiting rod inserted into the support rod, a spring is provided outside the limiting rod, and one side of the limiting rod is shaped as an inclined surface.

[0011] Preferably, a pad is provided on the inner wall of the clamping portion, and an anti-slip strip is provided on the inner wall of the pad. When the slide column slides to one side of the arc surface of the limiting rod, the inner wall of the pad contacts the outer wall of the crucible.

[0012] Preferably, a magnet one is provided on one side of the slide plate three, and a magnet two that attracts the magnet one is provided on one side of the support rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, after the clamping block relatively clamps the crucible by means of the fastening assembly, the staff can use the support rod to lift the crucible upward by one end to move the stop plate to the top of the furnace, and then simultaneously place the support rod downward. During the downward movement, the roller at the bottom of the stop plate will first contact the outer wall of the furnace, and under the elastic force of the torsion spring, the other rollers will also be relatively corrected during the rolling process with the outer wall of the furnace. When the multiple rollers on both sides of the crucible are corrected to be attached to the outer wall of the furnace during the falling process, the crucible in the clamped state will automatically be inserted into the deep center of the furnace in a vertical downward posture, further simplifying the more cumbersome alignment process of the old-fashioned clamps and making the alignment more efficient and convenient.

[0015] When the support rod drives the crucible to slide upward to the bottom thereof and separates from the furnace, the worker can use the handle to move the other end of the three-way slide groove of the slide plate. When the slide column moves to abut against the inclined surface of the limit rod, the limit rod will slide toward the outside of the support rod under the action of the spring until the slide column moves to the other side of the limit rod, and the elastic force of the spring will automatically reset the limit rod and limit the relative position of the slide column and the clamping block. In this state, the pad on the inner wall of the clamping part of the clamping block clamps the middle position of the crucible, so that when the worker uses the support rod to pour the glass solution in the crucible, a fulcrum is added, which further facilitates the worker to pour the glass solution.

[0016] 3. In the present invention, when the support rod drives the blocking plate and the roller to fall, the multiple rollers and the blocking plates cooperate with each other and resist the outer wall of the furnace at the same time, which can further increase the buffering effect of the crucible falling, and is more conducive to the control of the crucible by the staff in the clamping state, making the alignment work easier and more efficient.

[0030] See also Figure 1-11 The present invention provides a technical solution: a glass casting clamp. The solution solves the problem that the clamping method of the existing old-fashioned clamp is relatively simple and requires high proficiency. After clamping the crucible, it is necessary to master the clamping force and repeatedly move the position to align the bottom of the crucible with the inside of the furnace, and the overall operation is relatively troublesome.

Both the stopper 10 and the stopper 2 11 are fixedly connected to the fixing rod 9, and the stopper 10 is located at the top of the slide plate 8. A slide plate 2 12 is also provided on the outside of the fixing rod 9, and the stopper 2 11 is located at the bottom of the slide plate 2 12. The fixing rod 9 is fixedly connected to the slide plate 2 12, and the structure on one side of the slide plate 2 12 has exactly the same function as the support rod 3. An alignment component 14 is provided on the inside of the clamping block 13 for inserting the crucible 2 into the center position of the furnace 1 after auxiliary clamping. When the crucible 2 needs to be placed inside the furnace 1, the operator can simultaneously push the support rod 3 toward the inside of the furnace 1, so that the slide plate 1 8 and the slide plate 2 12 are close to each other, and further the clamping block 13 fixed to the outside of the connecting rod 7 clamps the outer wall of the crucible 2 at the same time. After the outer wall of the crucible 2 is clamped and tightened, the alignment component 14 can be used to quickly align the bottom of the crucible 2 with the center of the furnace 1, and keep it in a vertical state and placed inside the furnace 1 at all times, which is more conducive to the worker's operation and makes the overall operation process more convenient.

[0032] When the inner wall of the clamping block 13 is attached to the outer wall of the crucible 2, the side of the baffle 144 and the roller 17 will also contact the outer wall of the furnace 1. In this state, the clamping block 13 will clamp the crucible 2. The staff can use the support rod 3 to lift the crucible 2 upward by one end to move the baffle 144 to the top of the furnace 1. At this time, the support rod 3 is placed downward at the same time. In the process of moving downward, the roller 17 at the bottom of the baffle 144 will first contact the outer wall of the furnace 1, and under the elastic force of the torsion spring 15, the other rollers 17 will also be relatively corrected during the rolling process of the outer wall of the furnace 1. When the multiple rollers 17 on both sides of the crucible 2 are corrected to be attached to the outer wall of the furnace 1 during the falling process, the crucible 2 in the clamped state will automatically be inserted into the deep center of the furnace 1 in a vertical downward posture, further simplifying the more cumbersome alignment process of the old-fashioned clamp, making the alignment more efficient and convenient. At the same time, during the falling process, the multiple rollers 17 and the blocking pieces 144 cooperate with each other, which can further increase the buffering effect of the falling crucible 2, making it easier for the staff to control the crucible 2 in the clamping state.

[0034] When the crucible 2 needs to be clamped, the clamping block 13 can be moved to a relative height below the end of the crucible 2 first. The worker can use his hands to relatively fix the direction of the outer tube 41, and then turn the knob 43 to drive the threaded rod 42 to move toward the inside of the outer tube 41. At this time, the support rod 3 located outside the convex ring 44 will be displaced in the direction of movement of the threaded rod 42, and the support rods 3 located on both sides of the crucible 2 will approach at the same time, so that the two clamping blocks 13 clamp the crucible 2 to each other. At the same time, the worker can loosen the knob 43 at any time to put the crucible 2 in a more stable clamping state.

[0035] In addition, the support rod 3 in the present embodiment is provided with a clamping assembly 5 for cooperating with the clamping block 13 to clamp the outer wall of the crucible 2. The clamping assembly 5 includes a slide plate 3 51 located at the top of the support rod 3, a slide column 52 is provided on one side of the slide plate 3 51, a clamping block 53 is provided at one end of the slide column 52, and both ends of the slide column 52 are respectively fixedly connected to the slide plate 3 51 and the clamping block 53.

[0036] When the crucible 2 needs to be taken out, the crucible 2 can be clamped by the clamping block 13 first, and the support rod 3 can be lifted at the same time. When the support rod 3 drives the crucible 2 to slide upward to the bottom of the crucible 2 and separate from the furnace 1, the staff can use the handle 56 to move the slide plate 3 51 to the other end of the slide groove 55.
