Description

A kind of technology of the package for gear
Technical field
The invention belongs to Gear Processing fields, and in particular to a kind of technology of the package for gear.
Background technology
Gear refers to having gear continuously to engage transmission movement and the mechanical organ of power and common machinery on wheel rim to set The component of machine of most often feeding in standby, with passing power, speed change commutation function.The processing of gear generally has following 7 A procedure of processing, is followed successively by:1, different using casting, forging method gear blank according to requiring;2, it is heat-treated;3, gear blank Vehicle Processing;4, Gear hobbing or Gear Shaping;5, Shaving Process;6, the flank of tooth is heat-treated;7, roll flute or gear lapping.
After the completion of carrying out the 7th step of Gear Processing, generally can gear cleaned, packed or group successively again Dress, clean purpose are, remove the scrap on gear surface, scrap is avoided to be adhered on gear;Packaging is for the ease of right Gear is protected, and makes gear that nondestructive state, the two operating procedures be kept generally separately to carry out, have to the production efficiency of gear It influences;Simultaneously when being cleaned to gear surface, generally scrap is cleared up by the way of manual cleaning, the mistake of cleaning It is difficult to quickly and effectively be cleaned the scrap in adherency at tooth root in journey, can further influence the processing efficiency of gear.
Invention content
The invention is intended to provide a kind of technology of the package for gear, to improve the processing efficiency to gear.
In order to achieve the above object, base case of the invention is as follows:A kind of technology of the package for gear, including it is following Step:
Step 1:Prepare packaging material and several gears to be packaged;
Step 2:Prepare a kind of packaging facilities, include the first transfer drum and package mechanism for carrying out horizontal transmission to gear, The upper surface of first transfer drum is equipped with the feed inlet to fall vertically for gear, and package mechanism includes the buffer board of elasticity, first Electromagnet and the second electromagnet that can be attracting with the first electromagnet, the lower surface of the first transfer drum are in the cambered surface of evagination, and first passes The mounting groove for sending the bottom surface of cylinder to be equipped with installation buffer board, the upper surface of buffer board with feed inlet it is opposite, the first electromagnet is solid Dingan County is on the side of buffer board, and the second electromagnet is fixedly mounted on the other side of buffer board, the first electromagnet and second Electromagnet can be opposite with the flank of tooth of gear, and the electric heating of hot melt packaging material is equipped on the first electromagnet and the second electromagnet Silk;
Step 3:Buffer board in step 2 is installed in mounting groove, mounting groove can allow buffer board U-shaped, and at this time first Electromagnet is opposite with the second electromagnet;The packaging material in step 1 is laid on buffer board simultaneously, and the both sides of packaging material It is located on the first electromagnet and the second electromagnet;
Step 4:Gear to be packaged in step 1 is fallen on buffer board vertically by feed inlet, buffer board to gear into Row buffering waits for gear stationary in the cambered surface of the first transfer drum, and gear is located at the lower section of the first electromagnet and the second electromagnet, opens Dynamic first electromagnet and the second electromagnet, the first electromagnet and the second electromagnet attract each other, the first electromagnet and the second electromagnetism The both sides that sheet iron strip moves packaging material go in the same direction;
Step 5:After the both sides of the packaging material in step 4 fit, heating wire is opened, heating wire is with 100-200 DEG C Temperature heating 1-3s is carried out to the both sides of packaging material after, close the first electromagnet, the second electromagnet and heating wire, packing timber Material is bonded by hot melt, realizes the packaging to gear.
The principle and its advantage of base case:1, a kind of packaging facilities has been prepared in step 2, which can quickly have Effect packs gear, and when gear is transmitted in the first transfer drum, buffer board can avoid tooth to gear into row buffering Wheel damage;2, in step 3, buffer board is mounted in mounting groove, the buffer board convenient for elasticity is U-shaped, and then convenient in step The surrounding of rapid 4 middle gear is contacted with buffer board, realizes comprehensive buffering to gear;Packaging material is placed into buffer board simultaneously On, and the both sides of packaging material are located on the first electromagnet and the second electromagnet, are convenient in step 4, the first electromagnet When attracting each other with the second electromagnet, the packaging material on the first electromagnet and the second electromagnet can be fit together;3, exist In step 4, after gear stationary is in the cambered surface of the first transfer drum, it is then turned on the first electromagnet and the second electromagnet, it can It effectively prevents gear from being slided during packaging, can effectively improve the speed and precision of gear packaging;4, it walks In rapid 5, the temperature and duration opened to heating wire are limited, and can the both sides of packaging material effectively be carried out hot melt patch It closes, and after hot melt is bonded, the first electromagnet is separated with the second electromagnet, can quickly finish the packaging of gear.
In conclusion using a kind of packaging facilities in this method, which can delay the gear in transmit process It rushes, the gear after buffering is located in the cambered surface of the first transfer drum, and the first electromagnet and the second electromagnet can drive packaging at this time The both sides of material go in the same direction, and can open heating wire after the both sides fitting of packaging material carries out hot melt packaging to packaging material, Quickly gear can be packed.
Further, in the step 5, heating wire heats packaging material with 150 DEG C of temperature.The heating of heating wire Moderate temperature can ensure that the both sides of packaging material can quickly heat adhesion, can reduce the hot melt processing to packaging material Duration.
Further, in the step 5, a length of 2s when heating wire is to the heating of packaging material both sides.The heating of packaging material Duration is matched with the temperature of heating wire, and in the case where packaging material is sticky by hot melt, duration is heated in shortening that can be as possible, Promote the packaging efficiency of gear.
Further, in the step 2, the side of first transfer drum is equipped with first be inserted into for packaging material and leads to Hole, the other side of the first transfer drum are equipped with the second through-hole being inserted into for packaging material, and first through hole is located at the first electromagnet Upside, the second through-hole are located at the upside of the second electromagnet.Before being packed to gear, first successively by the free end of packaging material Across first through hole and the second through-hole, and packaging material is allowed to be laid on buffer board, the first electromagnet of heating wire pair and the second electricity Packaging material between magnet carries out hot melt cut-out;The heat of remaining packaging material melts place's adhesion together simultaneously, can pass through drawing The packaging material of dynamic second through hole, drives entire packaging material to continue to move to right, can packaging material be laid on buffer board again On, convenient for being packed to next gear.
Further, further include the push rod of Level Promoting gear in the step 2, one end of the push rod passes through first to pass Send the side of cylinder can be opposite with the end face of gear, and push rod and the second transfer drum sliding contact.Wait for that the packaging of a gear is completed Afterwards, laterally urge push rod, push rod pushes the gear after packaging to be moved to the direction far from feed inlet, convenient for next gear into Row packaging, while convenient for being collected to the gear after packaging.
