An adjustable stamping die with anti-jump waste

Abstract

The invention discloses an adjustable stamping mold for waste bouncing prevention, and relates to the technical field of stamping molds. The adjustable stamping mold for waste bouncing prevention comprises an upper mold and a lower mold which are connected in a sliding manner by a guide slide rod; a punch is in sliding connection in the upper mold, and a sliding cavity of the punch in the upper mold is in a shape with the upper end and the lower end having smaller diameters than that of the middle; the inner top of the punch is fixedly connected with an oil bag, an oil inlet pipe communicatingwith the inner cavity of the oil bag is inserted in one side of the top of the oil bag, the top end of the oil inlet pipe penetrates through the top of the punch, and a solvent bag is fixedly connected to the middle of the inner cavity of the oil bag. According to the adjustable stamping mold for waste bouncing prevention, controllable application of cutting oil on the surface of the punch is achieved by mechanisms, and based on control over the amount of the cutting oil, larger friction force between the punch and parts due to too little cutting oil can be effectively avoided, and normal useof the mold can be prevented from being influenced by excessive dripping of the cutting oil into the mold.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to an adjustable stamping die for anti-jump waste. Background technique [0002] Stamping die is a special process equipment for processing materials into parts in the process of cold stamping, also known as cold stamping die. At room temperature, the mold installed on the press is used to apply pressure to the material to cause separation or plastic deformation to obtain the required parts. However, in the actual production process of the stamping die, there is a phenomenon of skipping waste, that is, the waste jumps out of the lower die and falls to the lower template or other places. If the jumped out waste falls to the surface of the next processed workpiece, it will directly lead to the The machining of the workpiece fails and is scrapped, or in more serious cases, the scrap jumps out and falls and damages the mold or injures the worker. In the process of processing fer...

However, in the actual production process of the stamping die, there is a phenomenon of skipping waste, that is, the waste jumps out of the lower die and falls to the lower template or other places. If the jumped out waste falls to the surface of the next processed workpiece, it will directly lead to the The machining of the workpiece fails and is scrapped, or in more serious cases, the scrap jumps out and falls and damages the mold or causes injury to the worker

In the process of processing ferrous materials, due to the magnetism of the punch itself, or the magnetism caused by impact and friction, it is very easy to absorb waste and eject the waste based on inertia when the punch rises and stagnates, causing harm At the same time, if the amount and viscosity of cutting oil on the surface of the punch do not meet the standards, it is easy to cause the waste to further stick to the punch, resulting in material skipping
