Description

Cutting device is used in slips processing Technical Field The invention relates to the technical field of underground tool machining of oil and gas wells, in particular to a cutting device for slips machining. Background The packer is a key tool for underground operation of oil and gas well, and has the main functions of sealing different intervals in the well shaft, preventing fluid or pressure from flowing in layers, realizing core operations such as layered exploitation, layered water injection, fracturing and acidizing, etc., being widely applied to drilling, completion and repair of petroleum and natural gas, ensuring independent operation of each production layer by sealing annular space between the oil pipe and the casing, improving oil extraction efficiency and protecting well structure. In the process of setting the packer into a well, the slips are core components for realizing mechanical anchoring of the packer in the casing and preventing the packer from moving up and down, are key for guaranteeing long-term stable setting of the packer and playing the role of a sealing interlayer, and at present, the slips are processed by cutting a smooth cylindrical rod piece after a tooth slot is formed in the outer part of the rod piece, and then the whole rod piece after tooth forming is divided into a plurality of (eight) independent slip monomers by using cutting equipment. In the traditional processing flow of packer core component slips, the segmentation process relies on manual operation to accomplish for a long time, after cutting out a slips monomer, need to rotate whole member by manual work, adjust to the cutting operation of next slips after predetermineeing the angle, the manual intervention has prolonged whole processing cycle, is difficult to adapt to the rhythm of scale production, especially in the processing scene of high hardness alloy slips, cuts and the alternating operation of manual adjustment has further enlarged the efficiency short board, consequently we propose a cutting device for slips processing. Disclosure of Invention The invention aims to provide a cutting device for processing slips, which realizes accurate angle positioning of a cutting station by integrating an automatic indexing rotating mechanism, and can automatically drive blanks to rotate to a preset next cutting angle after finishing the cutting process of single slips, so that the cutting operation of multiple groups of slips can be continuously finished without manual intervention. The technical aim of the invention is achieved through the following technical scheme that the cutting device for slip processing comprises a frame, a band sawing machine sliding on the frame, a bottom plate arranged on the frame, a mounting plate sliding on the bottom plate and an air cylinder arranged on the bottom plate, wherein the output end of the air cylinder is connected with the mounting plate, two side plates are symmetrically arranged on the mounting plate, two saw cutting grooves are formed in the side plates, a fixing component is arranged on one side of the side plates, a rotating component is arranged on the other side of the side plates, two groups of transmission components are symmetrically and rotatably connected between the two side plates, the transmission components are in transmission fit with the rotating component through a belt, two groups of compensatory limiting components are symmetrically arranged on the mounting plate, and a pushing component with one end connected with the limiting components is slidably arranged on the limiting components. Through adopting above-mentioned technical scheme, to wait to cut the embryo material through fixed subassembly between the both sides board, make embryo material both ends paste tightly with fixed subassembly and rotation subassembly respectively, afterwards, spacing subassembly of front and back both sides supports tightly with the embryo material outside respectively, band sawing machine moves down, accomplish once saw cuts on the embryo material through saw cutting groove, after band sawing machine resets, the cylinder promotes mounting panel and embryo material and removes, band sawing machine moves down once more, saw cuts the embryo material twice, thereby realize the segmentation processing of single slips, spacing subassembly can carry out spacing constraint to the embryo material from front and back both sides in the saw cutting process, effectively guarantee saw cutting precision, avoid saw cutting position to appear the deviation. When the next slip is continuously cut, the rotating assembly starts to drive the rest of the blanks to rotate for forty-five degrees, the fixing assembly always keeps axially fixing the blanks in the rotating process, meanwhile, the rotating assembly rotates through the belt transmission assembly, and each time the rotating assembly rotates for forty-five degrees, the transmission assembly drives the pushing assembly to complete
