Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing equipment, specifically a hot pressing equipment for processing resin grinding wheels. Background Technology

[0002] The main raw materials of resin-bonded grinding wheels include abrasives and resin binders. Abrasives can be ordinary abrasives such as white fused alumina, brown fused alumina, and silicon carbide, or superhard abrasives such as diamond and cubic boron nitride (CBN). Resin binders are mostly phenolic, epoxy, polyurethane, and polyvinyl alcohol resins. Resin-bonded grinding wheels have high bonding strength, maintain stability under high-speed operation, and withstand high grinding pressure. Resin-bonded grinding wheels have wide applications in many fields, such as cutting discs, double-end facing, heavy-duty grinding wheels, and polishing wheels. They are widely used in rough grinding, finishing, cutting, and free grinding processes, such as grinding steel ingots and deburring castings. Simultaneously, resin-bonded grinding wheels can also be used for surface grinding, centerless external cylindrical grinding, grooving, and internal cylindrical grinding, making them ideal grinding tools for processing materials such as ultra-heat resistant stainless steel, cermets, ceramic products, glass products, limonite, high-speed steel, and alloy tools.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1:

[0024] Based on the existing problems of uneven heating, leading to unstable finished product quality, and uneven pressure distribution, which can easily cause dimensional deviations or shape distortions in the finished product when heating resin grinding wheel materials, the present invention provides a preferred embodiment of a hot pressing molding device for resin grinding wheel processing, for example... Figure 1-4The image shows a hot press molding device for resin grinding wheel processing, comprising a hot press base 1, a support frame 2 fixedly mounted on the top of the hot press base 1, a control display screen 3 fixedly mounted on the front of the support frame 2, a guide rail 4 fixedly mounted on the top of the hot press base 1, a protective plate 5 slidably connected to the outer wall of the guide rail 4, a transparent observation window 51 fixedly mounted on the front of the protective plate 5, and a pull handle 52 fixedly mounted on the front of the protective plate 5, with the pull handle 52 located on one side of the transparent observation window 51; and a hot press molding assembly 6, which is located above the hot press base 1. The hot press molding assembly 6 includes: a heating part 61, located above the hot press base 1; and a molding part 62, located above the hot press base 1, and positioned above and below the heating part 61.

[0025] The heating part 61 includes: a support column 611, which is fixedly installed on the top of the hot press base 1, and there are four sets of the support column 611; a protective shell 618, which is disposed on one side of the support column 611; a mounting plate 612 is fixedly installed on the top of the support column 611, and a forming base 613 is disposed below the mounting plate 612. The forming base 613 is fixedly installed on the top of the hot press base 1, and a heating cavity 614 is opened on the top of the forming base 613.

[0026] Heating resistance wire 615 is fixedly installed inside heating chamber 614. Support plate 616 is fixedly installed on the inner wall of heating chamber 614 and is located above heating resistance wire 615. Resin grinding wheel molding cavity 617 is opened on the top of molding base 613 and is located inside heating chamber 614.

[0027] The inner wall of the protective shell 618 is provided with a storage groove 619. The bottom of the inner wall of the storage groove 619 is fixedly installed with a sliding rail 6110, and there are two sets of sliding rails. The outer wall of the sliding rail 6110 is slidably connected with an L-shaped support frame 6111. The bottom of the L-shaped support frame 6111 is fixedly installed with a heating plate 6112.

[0028] Heating plate 6112 has a heating cavity 6113 at its bottom, and a heating resistance wire is fixedly installed on the inner wall of heating cavity 6113. A heat transfer plate 6114 is fixedly installed on the inner wall of heating cavity 6113.

[0029] Furthermore, this embodiment achieves all-round and uniform heating of the resin grinding wheel material by setting a heating chamber 614, a heating resistance wire 615, and a heating resistance wire in a heating chamber 6113 at the bottom of the heating plate 6112. This ensures the uniformity of preheating of the material before pressing, which is beneficial to improving the quality of the finished product. In conjunction with the heating plate 6112, which is slidably connected to the moving slide rail 6110 through the L-shaped support frame 6111, the position of the heating plate can be flexibly adjusted according to actual needs to adapt to resin grinding wheel materials of different sizes and shapes.

[0030] Example 2:

[0031] Please see Figures 1-4 Furthermore, based on Embodiment 1, the molding part 62 includes: a buffer spring 621, which is equidistantly and uniformly fixedly installed on the top of the molding base 613; a guide rod 623, which is fixedly installed on the top of the molding base 613, and there are four sets of guide rods, which are located at the four corners respectively; a mounting groove 628, which is opened at the bottom of the inner wall of the resin grinding wheel molding cavity 617 and extends to the bottom of the hot press base 1; a limiting guide plate 622 is fixedly installed on the top of the buffer spring 621, and the limiting guide plate 622 is adapted to the resin grinding wheel molding cavity 617; and a connecting block 624 is slidably connected to the outer wall of the guide rod 623.

[0032] A forming pressure plate 625 is fixedly installed between the connecting blocks 624. A hydraulic cylinder 626 is provided above the forming pressure plate 625 and is fixedly installed on the top of the mounting plate 612. A forming extrusion plate 627 is fixedly installed at the connecting end of the hydraulic cylinder 626 through a connecting rod and is fixedly installed at the bottom of the forming pressure plate 625.

[0033] A hydraulic ejector rod 629 is fixedly installed at the bottom of the inner wall of the mounting groove 628, and a molding mold 6210 is fixedly installed at the top of the hydraulic ejector rod 629. The molding mold 6210 is compatible with the resin grinding wheel molding cavity 617.

[0034] Furthermore, this embodiment provides stable support and guidance for the molding platen 625 by incorporating a buffer spring 621 and a guide rod 623, reducing molding defects caused by vibration or displacement. Combined with the hydraulic cylinder 626 and the hydraulic ejector rod 629, the molding and demolding process becomes more automated and convenient. Meanwhile, the protective shell 618 and the protective plate 5 protect the operator from high temperatures and mechanical movement. The transparent observation window 51 provides a clear view of the internal working conditions of the equipment, ensuring the safety and convenience of operation.

[0035] When the equipment is started, the heating element 61 at the top of the hot press base 1 begins to operate. The heating element 61 includes a mounting plate 612 fixed on the support column 611 and a forming base 613. A heating resistance wire 615 is fixedly installed inside the heating cavity 614 opened at the top of the forming base 613. When the heating resistance wire 615 is energized, it generates heat, which is transferred through the support plate 616 to the resin grinding wheel forming cavity 617 to preheat the resin grinding wheel material placed therein.

[0036] Simultaneously, the heating plate 6112, mounted on the bottom of the L-shaped support frame 6111 sliding on the movable slide rail 6110, also begins to operate within the storage groove 619 on the inner wall of the protective shell 618. A heating resistance wire and a heat transfer plate 6114 are also fixedly installed in the heating chamber 6113 at the bottom of the heating plate 6112, further heating the resin grinding wheel material to ensure uniform heating.

[0037] Furthermore, during the heating process, the molding section 62 is in a standby state. The buffer spring 621 and guide rod 623 on the top of the molding base 613 provide elasticity and guiding support for the molding platen 625. The limiting guide plate 622 fixed on the top of the buffer spring 621 ensures that the molding platen 625 can be accurately aligned with the resin grinding wheel molding cavity 617 when it descends.

[0038] Once the resin grinding wheel material has been preheated to the set temperature, the hydraulic cylinder 626 on top of the mounting plate 612 begins to operate. The molding extrusion plate 627, which is fixedly installed via a connecting rod, pushes the molding pressure plate 625 downward. The connecting block 624 slides on the guide rod 623, ensuring that the molding pressure plate 625 descends smoothly and presses the resin grinding wheel material into shape.

[0039] After molding is completed, the hydraulic cylinder 626 retracts, and at the same time, the hydraulic ejector rod 629 at the bottom of the inner wall of the mounting groove 628 begins to work. The molding mold 6210 fixed to the top of the hydraulic ejector rod 629 ejects the molded resin grinding wheel out of the resin grinding wheel molding cavity 617, making it easy to remove and process.

[0040] Throughout the operation, operators can monitor the equipment's operating status and various parameters in real time via the control display screen 3 fixedly mounted on the front of the support frame 2, ensuring the stability and efficiency of the production process. Meanwhile, the protective plate 5, along with its transparent observation window 51 and pull handle 52, not only ensures operator safety but also facilitates observation of the equipment's internal workings.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
