Abstract
Description
Technical Field
[0001] The utility model specifically relates to a grinding wheel forming blank turner. Background Art
[0002] The grinding wheel blank forming process is to mix the abrasive and the binder and put them into the mold, distribute the materials evenly, and then run the equipment to press down. When the pressure reaches the predetermined value, it is maintained for a period of time, and then the pressure is released and returned. The ejector cylinder ejects the finished product. After the grinding wheel blank is ejected from the mold, it is necessary to first place a grinding wheel flap on the upper end face of the grinding wheel blank. The grinding wheel blank with a metal base plate at the bottom is flipped manually (by two people), and then the metal base plate at the bottom of the original grinding wheel is replaced with a grinding wheel flap. The above process can only be done manually due to the lack of professional tooling. It is labor-intensive, low-efficiency, and requires two people to operate. Moreover, during the flipping process, once the hands slip out, it is easy to cause damage to the blank and personal injury. Utility Model Content
[0003] The purpose of the utility model is to provide a grinding wheel forming blank turner, which has a reasonable structure and can efficiently and safely complete the turning operation of the grinding wheel blank by only one person.
[0004] That is a grinding wheel forming blank turner, characterized in that it includes a fixed bracket, the fixed bracket includes a square fixed frame and 4 legs, a central axis is provided in the middle of the fixed frame, and a first plywood frame and a second plywood frame are hinged on both sides of the central axis, the first plywood frame is a T-shaped frame structure, including an integrated first vertical frame and a first horizontal frame, the inner end of the first vertical frame is hinged to the central axis, and the two ends of the first horizontal frame are provided with a first handle protruding upward perpendicular to the frame body, the second plywood frame is a T-shaped frame structure, including an integrated second vertical frame and a second horizontal frame, the two ends of the second horizontal frame are the second handles, the length of the second horizontal frame is the same as the distance between the two first handles, and a buffer sponge pad is also installed on the second plywood frame.
[0005] The length of the second transverse frame of the utility model is the same as the distance between the two first handles, that is, when the two clamping frames are in the clamping state, the two ends of the first transverse frame are just located inside the two first handles, so that the first handle and the second handle can be held conveniently at the same time.
[0006] The flipping principle of the present invention is as follows:
[0007] In the initial state, the two splint frames are placed horizontally on the fixed frames on both sides of the central axis. After the grinding wheel blank is ejected from the mold, one person moves the grinding wheel blank together with the metal base plate to the placement position of the first splint frame (the position will be marked in advance), and places a grinding wheel flap on the upper end face of the grinding wheel blank, and then flips the second splint frame 180°, clamping and fixing the grinding wheel blank between the two splint frames. At this time, the buffer sponge pad is attached to the grinding wheel flap on the upper end face of the grinding wheel blank. Hold the first handle and the second handle with your hands, maintain the holding force, flip the two splint frames 180° to realize the flipping of the grinding wheel. When the second splint frame contacts the fixed frame, the buffer sponge pad provides sufficient buffering protection. Hold the first handle with your hand, flip it 180° to reset it, remove the metal base plate on the upper end face, and replace the grinding wheel flap to complete the work.
[0008] With the help of the utility model, the above work can be completed efficiently by one person, and the grinding wheel blank is not easily damaged or fallen off to cause personal injury.
[0009] The buffer sponge pad of the present invention preferably has an area larger than the diameter of the grinding wheel blank. There is no need to strictly limit the installation position of the grinding wheel blank on the clamping frame. As long as the two clamping frames are clamped, the buffer sponge pad can completely cover the grinding wheel blank.
[0010] Furthermore, the second splint frame of the present invention is provided with a base for placing a buffer sponge pad, and the base and the second splint frame are connected by studs.
[0011] By rotating the base plate, the height of the buffer sponge can be changed to use grinding wheel blanks of different thicknesses.
[0012] For some larger and heavier grinding wheel blanks, it is difficult to maintain sufficient clamping force by manpower. In order to prevent the grinding wheel blank from moving during the flipping process, a locking device is further provided between the two clamping plate frames.
[0013] The locking device can adopt a locking device known in the prior art, for example, a bolt is provided on the first clamping plate frame, and a bolt hole is provided at a corresponding position of the second clamping plate frame, and the two are clamped and fastened with the bolt.
[0014] The present invention can also use various quick-open locks available on the market with existing technology, such as, preferably but not limited to, the tailgate locks currently used in small trucks (also known as rear trunk tailgate locks, compartment locks, etc.), which are convenient and quick to buckle and open. For example, the lock model DK080 of Laizhou Huiding Hardware Machinery Co., Ltd. can be selected, and the lock is installed on one of the plywood frames, and a lock ring is provided on the corresponding position of the other plywood frame.
[0015] The utility model can also provide a roller with a foot brake function at the lower end of the four legs, such as a Forma wheel, which can be moved to the vicinity of the forming device and fixed in position to facilitate the flipping work. After the flipping is completed, the grinding wheel blank can also be conveniently transferred to the next process.
[0016] The utility model has the advantages of reasonable structure, flexible and convenient use, high working efficiency and safety. After using the utility model, one person can complete the turning work of the grinding wheel blank, saving labor. BRIEF DESCRIPTION OF THE DRAWINGS
