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

Abstract

The invention discloses an inner spherical surface polishing device of a steel ball cold heading die, which comprises a placing plate, the four corners of the lower end of the placing plate are provided with supporting devices, and a mounting block is fixed on one side of the upper end of the placing plate, and the mounting block A plurality of clamping devices are provided at equal intervals at one end of the board, a first cavity is provided at both ends of the placement plate, a moving device is provided in the first cavity, and a moving device is provided at the upper end of the first cavity. The upper ends of the two moving plates are jointly fixed with a mounting plate, the upper end of the mounting plate is provided with a second fixed plate, and both sides of the upper end of the mounting plate are provided with slide rails. The invention solves the problem of inconvenient polishing of multiple moulds, improves work efficiency, can stably clamp the moulds, prevents the moulds from being damaged, and facilitates the adjustment of the grinding rods to fully polish the moulds, saving time, It saves manpower and material resources, is convenient to use, and has a protective effect on the device to prevent damage during operation.

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...
