Problems solved by technology

The forged products are often inconsistent in size, thickness and shape, and it is difficult to guarantee subsequent product processing. The surface of the product is rough and uneven, which is not beautiful
Moreover, the impact frequency and energy of the friction press are relatively low, the failure rate is high, and maintenance is often required, which delays production

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0011] Such as figure 1 , figure 2 , a new type of forging process for hand tools, including the following steps:

[0012] Step 1: Carry out three-dimensional modeling after the customer submits the drawing; and then obtain the forming mold program, trimming mold program and shaping mold mold through computer generation;

[0013] Step 2: mold manufacturing process; according to the forming mold program, the machining center directly makes the forming mold; according to the trimming mold program, the machining center directly makes the trimming mold; according to the shaping mold mold, the machining center directly makes the shaping mold;

[0014] Advantages: The machining center directly processes and forms, one step in place, saving trouble and labor, high processing precision, and the overall dimensions are exactly the same. The mold does not need...

Abstract

A novel forging method for a manual tool comprises the following steps S1. establishing a three-dimension model after receiving a drawing from a client, generating a program of a forming die, a program of a trimming die and a program of a shaping die using a computer; S2. manufacturing dies, directly manufacturing the forming die through a machining center according to the program of the forming die, directly manufacturing the trimming die through the machining center according to the program of the trimming die, and directly manufacturing the shaping die through the machining center according to the program of the shaping die; S3. forging, heating using the intermediate frequency after an automatic sawing machine saws material, pre-forging using a numerical control hydraulic forging hammer after heating using the intermediate frequency, final-forging after using the numerical control hydraulic forging hammer after pre-forging, trimming and shaping using a punch after final-forging to complete forging. By adopting the novel forging method for manual tool, the surface smoothness, the consistency and wear resistance of a die can be improved, and the processing efficiency is raised, and the flexibility of die manufacturing can be raised.

Description

technical field [0001] The invention belongs to the technical field of forging of mechanical tools, and in particular relates to a new forging process of hand tools. Background technique [0002] At present, the forging process in the hand tool industry generally uses electrode discharge technology to process product molds, and then manually grinds to improve the surface roughness of the mold, and then uses friction presses for forging processing. The forged products are often inconsistent in size, thickness and shape, which makes it difficult to guarantee subsequent product processing and production. The surface of the product is rough and uneven, which is not beautiful. Moreover, the impact frequency and impact energy of the friction press are relatively low, the failure rate is high, and maintenance is often required, which delays production. Contents of the invention [0003] The purpose of the present invention is to provide a new forging process for hand tools, whic...
