Abstract
The utility model discloses a welded cranked link chain, which comprises a plurality of cranked link plates. Pin holes are arranged at the two end parts of the cranked link plates. Adjacent cranked link plates are overlapped at the positions of the pin holes to form chains. Two chains are formed and are arranged in parallel. Sleeves are arranged between the two chains. The two ends of the sleeves are welded with the contact parts of the cranked link plates. The adjacent crank link chains are connected together at overlapped positions through pins which penetrate through the pin holes. The crank link plates are installed on guide rails. The upper ends and the lower ends of the side surfaces of the cranked link plates on the guide rails respectively undergo induction quenching treatment. The external surfaces except welded parts of the sleeves undergo the induction quenching treatment. The welded cranked link chain has the advantages that the structure is simple; and on the premise that the strength of the chain is not decreased, by conducting the induction quenching treatment process to the wear parts of welded links, the surface hardness of the parts is improved and the high-performance goal of wear resistance is achieved.
Description
Technical field
The utility model mainly is a kind of welding cranked link chain.
Background technology
The welding cranked link chain is to be applied to the wearing and tearing of intense impact, material and to contain the processing environment of a large amount of dust, like wood processing equipment, grain and oil Fabricating machinery and paper industry etc.Because the chain link of welding cranked link chain combines for welding; And the characteristic of welding process has determined that the chain link part can't be through improving resistance to abrasion like chemico-heat treatment modes such as carburizings, and therefore conventional welding chain link part is to adopt the modified heat treatment of medium-carbon steel to accomplish the chain link welding afterwards.In welding cranked link chain when operation,, carrier bar is on guide rail, to support operation, and the cliding friction that produces each other weares and teares the side end face of carrier bar easily, and the sleeve of chain link contacts concurrent looks to moving with the material of conveying, also can occur wearing and tearing.
The utility model content
The utility model technical matters to be solved provides a kind of welding cranked link chain; It is simple in structure; Under the situation of not sacrificing chain intensity; The worn-down position is taken place the welded chain joint has increased the induction hardening treatment process, improves the superficial hardness at these positions, to reach anti abrasive High Performance purpose.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of welding cranked link chain; Include a plurality of cranked plates; The end, two ends of described a plurality of cranked plates all has pin shaft hole, it is characterized in that: form a chain in pin shaft hole place stack between said a plurality of cranked plates are adjacent, described chain has two and be parallel to each other; Article two, be provided with sleeve between the chain, the contact site of sleeve two ends and cranked plate is welded to connect; Said adjacent cranked link chain superposed positions is passed pin shaft hole through bearing pin and is connected.
Described cranked plate is installed on the guide rail; The upper and lower end of cranked plate side carries out the induction hardening processing respectively on the guide rail; The outside face of said sleeve has adopted the induction hardening processing except the weld.
The residing strength weak of chain plate hole position has been avoided at the induction position of the upper and lower end of cranked plate side on the utility model middle guide, and so carrier bar intensity does not weaken.The induction hardening layer depth of carrier bar side end face reaches more than the 3mm, and superficial hardness is 55～60HRC.The quenching and tempering hardness of the original 30～38HRC of carrier bar is greatly improved so on year-on-year basis, and the polishing machine between carrier bar side end face and guide rail is greatly improved.
Welding on the chain link sleeve outer surface since with the convey materials direct contact, and have relative displacement to occur, the requirement of polishing machine equally sleeve is proposed.Because the two ends and the carrier bar of sleeve weld; Original superficial hardness (40～45HRC) is still kept in the weld; Non-weld (position that promptly contacts with convey materials) adopts induction hardening to handle, and its induction hardening layer depth reaches more than the 2.5mm, and superficial hardness is 55～60HRC; Thus, the polishing machine of sleeve outer surface is improved.
The utility model has the advantages that:
The utility model is simple in structure, and under the situation of not sacrificing chain intensity, the worn-down position is taken place the welded chain joint has increased the induction hardening treatment process, improves the superficial hardness at these positions, to reach anti abrasive High Performance purpose.

The specific embodiment
Referring to Fig. 1; A kind of welding cranked link chain includes a plurality of cranked plates 1, and the end, two ends of described a plurality of cranked plates 1 all has pin shaft hole 2; Between a plurality of cranked plate 1 is adjacent at pin shaft hole 2 places stack form a chain; Described chain has two and be parallel to each other, and is provided with sleeve 4 between two chains, and the contact site of sleeve 4 two ends and cranked plate 1 is welded to connect; Said adjacent cranked link chain 1 superposed positions is passed pin shaft hole 2 through bearing pin 3 and is connected.
Described cranked plate 1 is installed on the guide rail; The upper and lower end of cranked plate 1 side carries out the induction hardening processing respectively on the said guide rail, and induction Quenching Treatment district 5 is arranged; The outside face of said sleeve 4 has Quenching Treatment district 6 except the weld has adopted the induction hardening processing.
