Sword blank hot-rolling former and hot-rolling manufacturing method using same

Abstract

The invention relates to a hot-rolling sword blank manufacturing device and a hot-rolling manufacturing method thereof, in particular to a sword blank hot-rolling former and a hot-rolling manufacturing method using the same. The sword blank hot-rolling former comprises a feed mechanism, a high-frequency heating system, and a rolling machine. The high-frequency heating system is disposed between the feed mechanism and the rolling machine and comprises an induction coil pipe, a cooling water circuit system, a high-temperature cement block, a transformer, and an ultrasonic frequency induction heating device connected with the transformer. The high-temperature cement block is provided with a heating passage. A main part of the induction coil pipe is embedded into the high-temperature cement block. The induction coil pipe extends out of two ends of metal pipes in the high-temperature cement block and respectively electrically connected with the transformer; the interiors of hollow pipes of the metal pipes at two ends are further communicated with the cooling water circuit system. High-temperature cement material for the high-temperature cement block is made from cement, water, tricalcium aluminate, polyester fiber, retarder, and polypropylene fiber. The sword blank hot-rolling former heats up by high frequency, is high in production efficiency and good in safety, causes low pollution, and is good in machining quality.

Description

technical field [0001] The invention belongs to the field of sword processing, and in particular relates to a sword embryo processing equipment and a hot pressing method using hot pressing forming. Background technique [0002] At present, swords have gradually developed from weapons in ancient China into handicrafts collected by people or exercise equipment for exercising and displaying Chinese martial arts. Its nature and use have produced profound changes with the development of society. In Lishui Longquan, sword products have always been preserved as a cultural product, and gradually entered into industrialization and development. Therefore, the quality of swords needs to be continuously improved under this demand, and in turn, existing sword processing equipment and processing face many difficult technical problems.

Problems solved by technology

Therefore, the quality of swords needs to be continuously improved under this demand, and the existing sword processing equipment and processing face many difficult technical problems.

[0003] We know that traditional sword processing and production methods basically use manual forging technology, and then gradually undergo repeated heat treatment and finishing, and finally make the sword body. This kind of processing is labor-intensive and low in production efficiency. Difficult to control, greatly affected by human factors

Along with the development of sword making technology, the publication number is CN1458492A, and the disclosure date is pointed out a kind of making technology of sword blade in the Chinese invention patent application public specification on November 26, 2003, and it adopts mechanical roller to carry out cold pressing forming, After heat treatment and finishing, although this cold press forming method improves the production efficiency through mechanization and has a certain degree of automation, the sword processed by this method has the following defects: 1. The cold press forming method is harmful to the sword embryo. The material requirements are extremely high. The existing raw materials for swords are not only hard but also poor in plasticity. The cold press forming method is easy to cause fine cracks on the sword body, and the hardness requirements for mechanical equipment are high during processing.

2. Using mechanical rollers for cold pressing, due to the high hardness and poor plasticity of the initial sword embryo, it is easy to lead to a high scrap rate of mechanical rollers used as moulds.

The use of this kind of sword blank hot rolling forming machine can improve the processing efficiency by saving the two processes of slotting and grinding, but this kind of sword blank hot rolling forming machine uses ordinary electric heating devices for heating, but the sword The heating speed of the first embryo is slow. In addition, it takes a long time for the ordinary electric heating method to heat the first embryo to the hot red of the first embryo. It is easy to damage the processing equipment, and it is also very dangerous

Therefore, there are these deficiencies in this hot rolling forming machine equipment and hot pressing processing method, and it is difficult to meet the needs of sword processing machinery.
