Problems solved by technology

However, the traditional chain has some shortcomings in the convenience of tensile load. In some special occasions, the transmission chain not only needs to transmit objects, but also needs to bear a certain load-bearing force. The traditional chain is easy to wear or deform, resulting in its The service life is greatly reduced

Embodiment

[0021] Embodiment: a kind of production technology of the outer chain plate of transmission chain, comprises the following steps:

[0022] (1) Rolling: send the outer chain plate blank made of 40Mn steel stamped into the rolling machine for rolling treatment, which lasts for 20 to 40 minutes, and removes the surface burr of the blank;

[0023] (2) Marking: milling marks on the outer chain plate blank on the lathe;

[0024] (3) Rolling dirt: After step (2) is completed, the degree of surface pollution is detected, and the blank is sent to the rolling machine again according to the test result for rolling treatment, which lasts for 10 minutes;

[0025] (4) Heat treatment: send the blank into the heating furnace for hot forging for 2~4 hours, the specific steps are:

[0026] a. Send the blank into the heating furnace and heat it to 450~500°C, with a heating cycle of 10°C / min;

[0027] b. Keep warm for 30 minutes, water or oil cooled to 100°C;

[0028] c. Continue heating to 40...

Abstract

The invention discloses a production process of an outer chain plate of a transmission chain, which comprises the following steps: (1) rolling: sending the blank of the outer chain plate into a rolling machine for rolling treatment; (2) marking: the outer chain Milling mark on slab; (3) Rolling dirt: Send the blank to the roller machine again for rolling treatment; (4) Heat treatment: Send the blank to the heating furnace for hot forging for 2~4 hours; (5) Electroplating : After the hot forging is completed, it is air-cooled to room temperature and then electroplated; (6) Rolling: After electroplating, it is parked for 10 hours and sent to the rolling machine again; (7) Inspection: After the rolling is completed, the blank is taken out to obtain the finished product Outer chain plate. The outer chain plate of the transmission chain of the present invention is processed by multi-layer rolling to remove the surface contamination and impurities of the blank, and then heat treatment is performed to ensure the working strength of the outer chain plate. At the same time, after the outer chain plate is processed, the surface is electroplated. While beautifying the appearance, the ductility of the outer link plate is improved, so that the outer link plate has a higher tensile strength.

Description

technical field [0001] The invention belongs to the field of component processing, and in particular relates to a production process of an outer chain plate of a transmission chain. Background technique [0002] In the existing industrial production lines, a large number of transmission chains are used as important transmission components. The structure of the transmission chain is composed of inner chain links and outer chain links. The quality of the chain depends on the pin shaft and the sleeve. This transmission chain It is a multi-purpose mechanical transmission part composed of rigid components and a flexible system. It is mainly used to meet the functional requirements of transmission, transportation, and pulling. Among them, the roller chain is a widely used chain type, which is mainly composed of outer plates, inner plates, pin shafts, sleeves and rollers. However, the traditional chain has some shortcomings in the convenience of tensile load. In some special occas...
