Problems solved by technology

[0004] The main defect of the above-mentioned blanking device in use is: when the camshaft 4 falls from the slide part 1 on the material receiving part 2, since the camshaft 4 is still a high-temperature red-hot part, the surface does not have sufficient hardness, and it is easy to It directly collides with the material receiving plate of the material receiving part 2 to cause bump damage. These bump damage will affect the appearance of the parts and require additional subsequent grinding. In serious cases, the product will be scrapped due to i

Example Embodiment

[0026] Example 1

[0027] See figure 2 , figure 2 It is a blanking device of the present invention. The difference between the blanking device and the reference document 1 is that the material receiving part 2 is no longer a material receiving plate, but a metal wire arranged at intervals. This arrangement has at least the following effects: First, the camshaft 4 has a small contact area with the metal wire, and the metal wire is smooth throughout, avoiding collisions and bumps with the camshaft. Secondly, the sliding speed of the camshaft 4 on the metal wire is slowed to avoid falling inertia The risk of flying out of the receiving part 2.

Example Embodiment

[0028] Example 2

[0029] See image 3 , image 3 It is a more specific application of a blanking device of the present invention in a cross wedge rolling production line,

[0030] The cross wedge rolling production line includes a cross wedge rolling mill 5, the blanking device is integrally arranged at the blanking front end of the cross wedge rolling mill 5, and the sliding plate portion 1 of the blanking device extends into the forming part of the camshaft 4 between the two rolls of the cross wedge rolling mill 5 , The sliding plate part 1 of the blanking device is connected with the end of the bracket 3 close to the cross wedge rolling mill 5, and the connection method is welding. In order to make the camshaft 4 and the sliding plate part 1 form a sufficient buffer, the sliding plate of the sliding plate part 1 is designed to be arc-shaped Structure, the bottom of the end of the support 3 close to the cross wedge rolling mill 5 is hinged together with the ground support 6 se...

[0035] Example 3

[0036] The blanking device of the present invention, such as the mechanical connection structure and the transmission device described in Embodiment 1 and Embodiment 2, is easy to understand. It achieves higher production efficiency through simple actions, which is an essential part of the present invention. In the process, the material selection, manufacturing and installation of the metal wire are very critical technologies.

[0037] After continuous attempts, a Ni-based alloy with a Fe content of 10%-16% by weight was finally selected as the metal wire material of this application. The Ni-based alloy is a relatively good high-strength heat-resistant alloy with a reasonable formula The Ni-based alloy wire can exhibit higher heat resistance and deformation resistance. Preferably, the Ni-based alloy with a Fe content of 10%-16% by weight also includes the following components (weight percentage): 15- 20% Cr, 0.5-2% Al, 2.5-3% Mo, 0-1.2% W, 5-10% Co, and the carb...

Abstract

A blanking device for receiving thermoformed parts in metal thermal processing, comprising a material receiving part and a bracket, the material receiving part is a metal wire arranged at intervals, and the metal wire is 10% by weight of Fe ‑16% Ni-based alloy, the hot-formed part is a camshaft, the metal is hot-processed by cross-wedge rolling, and a slide part is also included, and the slide part is connected to one end of the bracket close to the cross-wedge rolling mill Connected, the bottom of the end of the bracket close to the cross wedge rolling mill is hinged with the ground support on the ground through the hinge frame, and the bottom of the end of the bracket away from the cross wedge rolling mill is hinged with the piston of the lifting cylinder through the hinge block The ends of the rods are hinged together, and a cooling groove is placed at the bottom of the support, and cooling water is installed in the cooling groove.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a blanking device, which can be used in forging or rolling production lines to prevent bumps on product surfaces. Background technique [0002] Both forging and rolling are commonly used processes for thermal processing of metal profiles. Forging is to use impact force or pressure to deform the metal between the iron or forging die, so as to obtain forgings of the required shape and size. Rolling is to pass the metal blank through a For the gap (various shapes) of rotating rolls, due to the compression of the rolls, the material section is reduced and the length is increased. The pressure processing method, forging and rolling are all important forming methods of metal parts, which can ensure that metal parts have Good mechanical properties to meet the requirements of use. [0003] Products formed on forging equipment (hammers, presses, etc.) figure 1 It is a blanking devi...
