The front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but also are safety devices that absorb and mitigate external impact forces, protect the body and protect the body and occupant safety functions.
The geometry of the bumper should be considered in the same way as the shape of the vehicle, to ensure the appearance, but also to meet the mechanical characteristics and energy absorption characteristics, to ensure the vibration absorption and slowness during impact.

Many consumers don't know much about quenching machine tools, and they tend to go wrong when they purchase quenching machine tools. Here we will summarize the knowledge we need to know about quenching machine purchase.
First of all, when we purchase the quenching machine tool, we should clarify the purpose of our use, and determine the type of quenched machine tool according to the purpose of the application.
1. Usually hydraulic quenching machines are used in relatively large workpieces. The main reason is that the equalization requirements for quenching are not particularly high.
2. Programmable or numerically controlled high-frequency machine tools have changed the cumbersome structure and operating modes of traditional machine tools. Now the form of the machine tool is mostly simple, with advanced control system, which improves the quenching speed of the quenching machine tool. It can also meet the requirements for the machine tool with higher quenching technology requirements. Especially for the quenching control system that plc becomes, the quenching quality of the quenching machine can be greatly improved, and the machining efficiency of the workpiece can be improved.
3. The mechanical stability of the quenching machine, the specification of the component selection and the practicality of the control system for high-frequency technology are the criteria for judging the performance of the quenching machine. The performance of high-frequency quenching machine tools also determines the quality of the entire quenching process. It is also a problem we need to pay attention to when choosing quenching machine tools.
The outer plate and the cushioning material are made of plastic, and the beam is stamped into a U-shaped groove by a cold-rolled sheet having a thickness of about 1.5 mm; the outer plate and the cushioning material are attached to the beam, and the beam is screwed to the frame longitudinal beam, and can be attached at any time. Remove it. Plastics used in such plastic bumpers are generally made of two types, polyester and polypropylene, and are injection molded.
What are the main points for the purchase of quenching machine tools?
Quenching machine tools are mainly vertical quenching machine tools and horizontal quenching machine tools in two forms, when we buy quenching machine tools should be based on their own needs to choose the type of quenching machine. If we have special technical requirements in special fields or for quenching machine tools, we shall produce a dedicated machine tool according to the purpose of use.
