Description
Technical field
The utility model relates to a kind of making mould of diamond segment, and a kind of side is the cold stamping die of the fan-shaped diamond segment of circular arc specifically.
Background technology
Diamond segment is generally made by the metal dust that contains diamond particles, and the processing method of diamond segment is divided into two steps: at first be cutter head cold moudling, it is hot-forming to carry out afterwards cutter head.Common diamond segment cold moudling is the needed shape of straight forming cutter head on cold stamping die.Cold stamping die is made of the former that is used in conjunction with each other, seaming chuck, three parts of push-down head, former after the assembling, seaming chuck, push-down head form the needed die cavity of cutter head, the fixing periphery of cold stamping die, can not deform after making the cavity pressurization, then in cavity, add the metal dust of making cutter head, and add high pressure, stop pressurization when making metal dust by the loose solid shape that becomes required cutter head shape, take out diamond segment after the unloading, diamond segment is cold moudling thus, then turns hot pressing process.
At present, the side is that the cold stamping die of the fan-shaped diamond segment of circular arc comprises: former, seaming chuck, push-down head, core rod, five parts of middle plate, the process of cold moudling all is pure manual operation.Processing step is: 1, assembled by hand part, and 2, manually take by weighing powder, add powder, 3, the manual seaming chuck of packing into, 4, extrusion forming, 5, manually break mould and take out cutter head.Adopt this mould and technique, ratio of briquetting is low, and per step all be the manual operations, each workman can only see a chilling press, production efficiency is extremely low, adds that whole cold moudling process all is manually-operated, causes security incident easily.
Conventional automatic cold-press mould generally is used for all cold moudling of identical diamond segment of arbitrary shape of cross section, comprise former, seaming chuck, three parts of push-down head, former, seaming chuck, push-down head adopt straight barrel type structure unanimous between the higher and lower levels to get final product, the plane that is the through hole shape of cross section of former and diamond segment is corresponding, and upper and lower pressure head shape of cross section matches with the through hole shape of cross section of former.But be the fan-shaped diamond segment of this special shape of circular arc for the side, just need in the former hole, add accessory with circular arc with the adjusting type cavity shape, because chilling press is merely able to connect a seaming chuck of control and a push-down head, can not control the accessory in order to guarantee that the side circular arc adds, so the accessory that adds with circular arc can cause a lot of problems, for example can not automated packing, can not automatically take out cutter head, more can not automatically control the desired appearance and size of smooth and cutter head of cutter head arc surface.
The utility model content
The utility model technical issues that need to address provide the cold stamping die that a kind of side is the fan-shaped diamond segment of circular arc, can realize that the side is the automated production of the fan-shaped diamond segment cold moudling of circular arc, can enhance productivity, reduce production costs.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The side is the cold stamping die of the fan-shaped diamond segment of circular arc, comprise the socket type former with mounting flange, the seaming chuck and the push-down head that are used with former, be provided with the scallop hole that axially runs through on the described former, it is the corresponding groove of arc surface of the fan-shaped diamond segment of circular arc that the bottom surface of described seaming chuck is provided with the side, the degree of depth of described groove is corresponding with the thickness of cutter head, the end face of described push-down head for the side be the following corresponding plane of the fan-shaped diamond segment of circular arc, the position that push-down head is corresponding with boss on the seaming chuck bottom surface has the seam ladder, be provided with in the scallop hole of described former with the seaming chuck bottom surface on boss and the seam ladder position of push-down head is corresponding and the fan-shaped pressure head side plate contour with former of working in coordination; Be provided with the magnet A for the cutter head after absorption pressure head side plate and the moulding in the boss on the described seaming chuck bottom surface, described pressure head side plate is provided with the magnet B corresponding with magnet A in the upper surface; Be provided with hole clipping on the lower outside disc of described pressure head side plate, in the former one side corresponding with the pressure head side plate be provided with hole clipping corresponding be with bayonet lock springy.
Further improvement of the utility model is: described bayonet lock is arranged in the radial hole of former, and by holding screw and spring top clamping.
Further improvement of the utility model is: the scallop hole of described former has at least three.
Further improvement of the utility model is: the top of the hole clipping on the described pressure head side plate and the top contact site of bayonet lock all arrange the inclined-plane that is slidingly matched.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Adopting side of the present utility model is the cold stamping die of the fan-shaped diamond segment of circular arc, realized that the side is the automated production of the fan-shaped diamond segment cold moudling of circular arc, improved the ratio of briquetting of diamond segment, and only operate a chilling press by an original workman and be improved to a workman and can look after five chilling press, the running status that the workman only need observe machine gets final product, and has reduced workman's labour intensity, has saved manpower, improve efficient, reduced cost.
The fan-shaped cavity that former and pressure head side plate form can the moulding cutter head fan-shaped profile, the side circular arc that the groove of seaming chuck can the moulding cutter head.
The pressure head side plate the boss width that can widen the seaming chuck bottom surface is set, and then strengthen the intensity of seaming chuck groove, so that seaming chuck is more strong in the process of compacting cutter head.
Magnet A in the seaming chuck bottom surface convex platform and the magnet B pressure head side plate upper surface in are used for seaming chuck and have suppressed when returning behind the cutter head absorption pressure head side plate and get back in the hole of former, with the correct die cavity of formation filling powder.
Hole clipping on bayonet lock in the former radial hole and the pressure head side plate lower outside disc is used, form link gear with spring and holding screw, the position that is used for restriction pressure head side plate, namely when seaming chuck presses down, under the pressure of pressure head side plate, bayonet lock holddown spring setback former radial hole, the pressure head side plate is descending with seaming chuck, so that the metal powder in the die cavity is pressed into cutter head; After having suppressed, when seaming chuck was up, when the pressure head side plate went upward to the hole clipping of bayonet lock insertion pressure head side plate with seaming chuck, the pressure head side plate stopped up, and the pressure head side plate is stayed in the former scallop hole to form the correct die cavity of filling powder.
