Description

Novel grinding wheel rotary press

Technical Field

The utility model relates to a emery wheel preparation field, concretely relates to novel emery wheel is changeed and is pressed machine.

Background

The grinding wheel is also called a consolidation grinding tool, and is a consolidation grinding tool which is formed by consolidating common grinding materials into a certain shape (mostly circular, with a through hole in the center) by a bonding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. According to different classes of binders, ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels are common. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.

Grinding wheels are the most important type of grinding tool in grinding operations. The grinding wheel is a porous body prepared by adding a binding agent into an abrasive, compacting, drying and roasting. Due to the differences of the grinding materials, the bonding agents and the manufacturing process, the characteristics of the grinding wheels are greatly different, and therefore, the grinding quality, the production rate and the economy are greatly influenced. The properties of the grinding wheel are mainly determined by the factors of abrasive, granularity, bonding agent, hardness, texture, shape, size and the like.

The superhard grinding wheel is usually made of cubic boron nitride or artificial diamond with different grain sizes, and the raw materials with various grain sizes are required to be mixed when the grinding wheel is prepared.

The basic manufacturing steps of the grinding wheel are firstly pressing and then sintering, a rotary press (pressing machine) is needed in the pressing process, the grinding wheel needs to be taken out of a die in a key step after pressing, the die needs to be lifted generally, then the grinding wheel is pressed out of the lower side of the die through a pressure head, an operator needs to tilt the grinding wheel through a crow bar, and then a cushion block is plugged below the grinding wheel, and the operation mode has the following problems: the emery wheel falls easily to the workstation when falling out from the emery wheel mould on, damages the emery wheel, and the emery wheel mould is heavier, consumes manpower and materials.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel emery wheel rotary press machine, can be convenient take out the emery wheel after will suppressing, suppress efficiently.

Realize the technical scheme of the utility model is that:

a novel grinding wheel rotary press comprises a workbench and a pressing device, wherein the workbench is provided with a base, the base is provided with a mold groove, a stand column is arranged in the mold groove, and the mold groove and the stand column are provided with bottom molds; the pressing device comprises a pressing column and a central hole.

The bottom die includes a reverse-buckled L-shaped part and an ━ -shaped part arranged in the die groove, the L-shaped part and the ━ -shaped part are integrally arranged, and the outer end of the bottom die is tightly connected with the inner wall of the die groove.

The inner diameter of the central hole is matched with the outer diameter of the bottom die, and the depth of the central hole is larger than the height of the bottom die.

And a pull ring is arranged at the upper end of the bottom die.

The electromagnetic valve is arranged in the workbench, the bottom die is made of magnets, and the bottom die is matched with the electromagnetic valve.

The utility model has the advantages that: the utility model discloses set up the die block in emery wheel embossing mold utensil inslot, the die block can be followed the mould inslot and taken out, after the suppression, can follow the mould inslot with the emery wheel through the die block and take out, and the method is simple and easy.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, a novel grinding wheel rotary press comprises a workbench and a pressing device, wherein the workbench is provided with a base 1 (fig. 4), the base 1 is provided with a mold groove 2, the mold groove 2 is internally provided with a stand column 3, and the mold groove 2 and the stand column 3 are provided with a bottom mold 4; the pressing means comprise a pressing stud 5 and a central hole 6 (fig. 3).

As shown in fig. 2, the bottom die 4 includes a reverse-bar 7 and an ━ 8 in the die cavity 2, the reverse-bar 7 and ━ 8 are integrally formed, and the outer end of the bottom die 4 is closely connected to the inner wall of the die cavity 2. When in use, the bottom die 4 is placed in an inverted manner at the position shown in figure 1, and the bottom of the bottom die 4 is in close contact with the inner walls of the die groove 2 and the die groove 2. Later put into the inslot that die block 4 and mould groove 2 inner wall are constituteed with the emery wheel compounding, after the suppression, pull ring 9 is upwards pulled out emery wheel and die block 4, and the emery wheel can also get rid of the deckle edge of emery wheel with 2 inner wall friction in-process in the mould groove.

Preferably, the inner diameter of the central hole 6 is matched with the outer diameter of the bottom die 4, and the depth of the central hole 6 is greater than the height of the bottom die 4. Because the pull ring 9 is arranged on the bottom die 4, when the pressing device presses the lowest end, the pull ring 9 is arranged in the central hole 6, and the inner wall of the top end of the central hole 6 has a certain distance with the pull ring 9, so that the pull ring can be arranged in the central hole 6 without affecting pressing.
