Device for polishing internal spherical surface of steel ball cold heading mold

Abstract

The invention discloses a device for polishing an internal spherical surface of a steel ball cold heading mold. The device for polishing the internal spherical surface of the steel ball cold heading mold comprises a placing plate; supporting devices are arranged at four corners of the lower end of the placing plate; a mounting block is fixed on one side of the upper end of the placing plate; multiple clamping devices are arranged at one end of the mounting block in an equally spaced manner; first cavities are formed in the two ends of the placing plate; moving devices are arranged in the firstcavities; moving plates are arranged at the upper ends of the first cavities; a mounting plate is mutually fixed at the upper ends of the two moving plates; a second fixing plate is arranged at the upper end of the mounting plate; and slide rails are arranged on the two sides of the upper end of the mounting plate. According to the device for polishing the internal spherical surface of the steelball cold heading mold, the problem that the polishing of multiple molds is inconvenient is solved, the working efficiency is enhanced, the molds can be stably clamped to be prevented from being destroyed, the adjusting of a grinding rod is made convenient, the molds are sufficiently polished, the time is saved, manpower and material resources are saved, the use is convenient, and a protection effect on the device is realized to prevent the device from being damaged in the operation process.

Description

technical field [0001] The invention relates to the technical field of cold heading dies, in particular to an inner spherical surface polishing device of a steel ball cold heading die. Background technique [0002] The cold heading process is one of the new processes of metal pressure processing without cutting. It is a kind of plastic deformation produced by the metal under the action of external force, and with the help of the mold, the metal volume is redistributed and transferred to form the desired shape. The processing method of parts or blanks, the cold heading process is most suitable for the production of standard fasteners such as bolts, screws, nuts, rivets, pins, etc. Steel ball cold heading dies often need to be processed before use. [0003] Molds, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, etc. to obtain the required products, in short, molds are tool...

Problems solved by technology

[0006] The patent of CN107571136A discloses a spherical surface polishing device in a steel ball cold heading die. The rotation of the driving gear and the impulse gear simultaneously drives the joint rotation of the first auxiliary rotating shaft, the second auxiliary rotating shaft and the third auxiliary rotating shaft, which can simultaneously Polishing multiple steel ball cold heading dies, however, the research found that the required equipment does not have a convenient position to adjust the grinding rod, and it is inconvenient to clamp the dies;

[0007] The patent of CN108312044A discloses a polishing device, which polishes steel through semi-automatic fixed rotation. It is found that the required equipment is inconvenient to clamp the cylindrical mold, and it is easy to throw it out during the rapid flipping process;

[0008] The patent of CN105269441B discloses a kind of polishing device, through reinforcing seat, telescopic beam, clamping foot, the rotating frame that is screwed on the upper end of described telescopic beam, the first plate body that is arranged on the upper end of described rotating frame and screwing The lifting knob on the lower side of the telescopic beam is used to adjust the polishing device, which is convenient for operation. However, it is found through research that the required equipment is inconvenient to polish multiple molds at the same time, and the polishing efficiency is low;

[0009] However, the existing spherical surface polishing device for steel ball cold heading dies is inconvenient to stably clamp the dies when polishing the dies, and may cause damage during polishing, and cannot simultaneously polish multiple dies. It is low, wastes time, wastes manpower and material resources, and the grinding rod is inconvenient to adjust, so that the mold can be fully polished. Therefore, we have proposed a spherical surface polishing device for steel ball cold heading molds to solve the above problems
