Pellet die positioning device and abrasive disc abrasive material pellet die unloader

Abstract

The invention provides a pellet die positioning device and an abrasive disc abrasive material pellet die unloader. The abrasive disc abrasive material pellet die unloader comprises a rack, wherein a pellet die positioning device and a die unloading device are arranged on the rack; the die unloading device comprises a driving mechanism and an ejection squeezing head; the pellet die positioning device comprises a positioning bottom plate horizontally arranged, a V-shaped positioning block is arranged on the positioning bottom plate, and the V-shaped positioning block is assembled on the positioning bottom plate in a manner of guiding and moving perpendicular to the vertical direction; a locking structure used for locking the V-shaped positioning block and a fixing structure used for fixing a pellet die are further arranged on the positioning bottom plate; a squeezing head channel allowing the upward ejection of the ejection squeezing head is arranged on the positioning bottom plate and in a position vertically corresponding to the ejection squeezing head; and the axis of the ejection squeezing head is positioned on the symmetrical central surface of two positioning slopes of the V-shaped positioning block. The abrasive disc abrasive material pellet die unloader is simple in structure and convenient to use, can realize the unloading of various sizes of pellet dies through the adjustable V-shaped positioning block, and is high in universality.

Description

technical field [0001] The invention relates to a pill mold positioning device and a grinding disc and abrasive pill mold unloading machine. Background technique [0002] At present, the production process of super-hard abrasive discs mainly consists of the following two processes: the first is the overall sintering and pressing method, that is, the mixed super-hard abrasive is added to the mold, and the powder is flattened by the spreading device, placed on the press The head cover plate, and then the mold is placed under the press and pressed while sintering, and finally processed. The second is the split pressing and bonding method, which presses the abrasive pellets one by one through the pellet mold. After the pressing is completed, the pellets are unloaded from the pellet mold and taken out for sintering treatment. Finally, a complete pellet is formed by bonding the pellets. super hard grinding disc. At present, the second process method is widely used, and the proce...

Problems solved by technology

However, because the size and shape of the pills that make up the grinding disc are different, and the number and types are large, the pressing and unloading process is more complicated.

[0003] The traditional method of pressing and unloading the mold is generally to use a small tonnage press equipped with different types of molds for pressing, and then install different mold unloading tools on the press for unloading, so that the same press is used for pressing and unloading. And pill molds of different sizes need to be equipped with different mold unloading tooling, which reduces the effective utilization rate of the equipment and lower work efficiency

In addition, when unloading the mold, it is necessary to place the pads and ejector pins on the upper and lower surfaces of the mold, and observe the downward position of the press to prevent the pressure head from overtraveling and damage the pills, which is very inconvenient to operate; During the molding process, the ejector pin and the cushion block will rub when they are in contact, resulting in burrs on the pellets after demolding; at the same time, the mold needs to be held by hand to prevent the mold from sliding during the demoulding process, which poses a safety hazard

Based on the above problems, the existing mold unloading method is very troublesome and takes a long time
