Problems solved by technology

[0003] The commonly used blanking device in the prior art generally includes a slide part, a material receiving part and a bracket. After the parts are processed, they drop from the main machine on the slide part, and then drop from the slide part onto the material receiving plate of the material receiving part. Workers use special clamps or mechanical arms to clamp the camshaft dropped on the material receiving part and put it into the turnover box or material box. The main defect of this type of blanking device in use is: When dropped on the material receiving part, since the part is still a high-temperature red-hot part, the surface is not sufficiently hard, and it is easy to directly collide with the material receiving plate of the material receiving part to cause bump damage. It is necessary to increase the follow-up grinding. In severe cases, the product will be scrapped due to insufficient follow-up processing allowance. On the other hand, it is also because the parts are still high-temperature red-hot parts. The heat exchange area of ​​the parts and the receiving plate is large, and it is difficult to apply cooling means. The receiving plate is quickly distorted and deformed, so it is easier to collide with the product, and needs to be replaced very frequently, which greatly increases the production cost

Embodiment 1

[0028] see below figure 2 , figure 2 It shows that the blanking device of the present invention has used the metal wires arranged at intervals, and the structure of the wires arranged at intervals is completely different from the receiving plate of the traditional technology, and the metal wires arranged at intervals have played the following roles at least: first, the cam The contact area between the shaft 4 and the metal wire is small, and the metal wire is smooth throughout, which avoids collisions and bumps with the camshaft. Secondly, the sliding speed of the camshaft 4 on the wire is slowed down, avoiding flying out of the connection due to the inertia of the drop. Part 2 risk.

[0029] exist figure 1 Among them, the material receiving part 2 adopts the metal wire structure arranged at intervals, which achieves higher production efficiency through a simple structure.

[0030] As an indispensable part of the present invention, the material selection and manufacture a...

Embodiment 2

[0037] In this embodiment, the material and manufacturing process of the metal wire are further optimized.

[0038] The Ni-based alloy with a weight percentage content of Fe between 10% and 16%, specifically selects 14% Fe content by weight percentage, and also includes the following components (weight percentage): 15% Cr, 0.5% Al, 3 % Mo, 0.2% W, 7% Co, 0.5% C.

[0039] The deformation rate of each section of the wire drawing process is 30%, and the finished product is heat-treated at a constant temperature of 720°C for 12 hours.

Embodiment 3

[0041] The difference between this embodiment and embodiment 2 is:

[0042] The Ni-based alloy with a weight percentage content of Fe between 10% and 16%, the Fe weight percentage content is specifically selected as 16%, including the following components: 20% Cr, 2% Al, 2.5% Mo, 0.9 % W, 5% Co, 0.8% C.

[0043] The deformation rate of each section of the wire drawing process is 35%, and the finished product is heat-treated at a constant temperature of 750°C for 6 hours.

Abstract

A metal wire installed on the material receiving part of the blanking device for receiving thermoformed parts in metal thermal processing, the metal wires are arranged at intervals, and the weight percentage of Fe is 10%-16% Ni-based alloy between, also includes the following composition (weight percentage): 15‑20% Cr, 0.5‑2% Al, 2.5‑3% Mo, 0‑1.2% W, 5‑10% Co , 0.3-0.8% C; adopt forging-continuous rolling-drawing process to make the metal wire; the blanking device equipped with the metal wire is integrally arranged on the blanking of the metal thermal processing equipment At the front end, after the thermoformed parts dropped on the material receiving part are clamped out of the blanking device, the lifting cylinder is operated to retract the piston rod of the lifting cylinder, thereby driving the bracket to tilt towards the ground, so that the bracket on the At least the middle hanging part of the metal wire in the material connection part is immersed in the cooling water of the cooling tank for rapid cooling.

Description

technical field [0001] The invention relates to the field of mechanical equipment accessories, in particular to a metal wire used in a blanking device. The blanking device with the metal wire is used in thermal processing (such as forging and rolling) of metal profiles. The invention provides Fabrication and online cooling methods of metal wires. Background technique [0002] Forging and rolling are one of the important forming methods of metal parts. It can ensure that metal parts have good mechanical properties to meet the requirements of use. Products formed on forging equipment (hammers, presses, etc.) generally pass through blanking devices Or the conveying device undertakes, and then is filled and circulated through the turnover box or material box. [0003] The commonly used blanking device in the prior art generally includes a slide part, a material receiving part and a bracket. After the parts are processed, they drop from the main machine on the slide part, and ...
