Embodiment Construction
[0009] Combine below Figure 1-Figure 3 The present invention is discussed in further detail.
[0010] A hydraulic side punching device, comprising a workbench 10, on which a workpiece A to be punched is fixed, on which a main hydraulic cylinder 20 is arranged, and a driving mechanism 30 drives the main piston rod 21 of the main hydraulic cylinder 20 to move, The main hydraulic cylinder 20 is connected to the auxiliary hydraulic cylinder 40 through the hydraulic pipeline B, and the end of the auxiliary piston rod 41 of the auxiliary hydraulic cylinder 40 is connected with a punch 42, and the auxiliary piston rod 41 is controlled to go back and forth through the main hydraulic cylinder 20 to enter and return oil. The motion drives the punch 42 to punch and return. Under the premise of not changing the main structure of the original mold and the stamping process, the wedge punching method is changed to the hydraulic punching method, the mechanical energy of the press is convert...

The invention discloses a hydraulic side punching device capable of reducing energy consumption, low in noise and high in technology level. The hydraulic side punching device comprises a workbench. A to-be-punched piece A is fixed to the workbench. The workbench is provided with a main hydraulic cylinder. A drive mechanism drives a main piston rod of the main hydraulic cylinder to move. The main hydraulic cylinder is connected with an auxiliary hydraulic cylinder through a hydraulic pipeline B. The end portion of an auxiliary piston rod of the auxiliary hydraulic cylinder is connected with a punch. Through oil inflow and oil return of the main hydraulic cylinder, the auxiliary piston rod is controlled to reciprocate to drive the punching and returning actions of the punch. On the premise that an original die body structure and the punching technology are not changed, the wedge punching manner is changed into the hydraulic punching manner, mechanical energy of a press is converted into fluid pressure energy of the main hydraulic cylinder, then fluid pressure energy is converted into mechanical energy, and energy consumption is reduced; and meanwhile, due to the flexibility of the hydraulic pipeline B, distribution is relatively convenient, and the complex punching technology requirement can be met.
Description
technical field [0001] The invention relates to the technical field of design and manufacture of automobile molds, in particular to a hydraulic side punching device. Background technique [0002] In the production of stamping dies, side punching is often encountered on the surface of products, such as automobile side panels, fenders, rear door outer panels and other products. In the prior art, a wedge mechanism is usually used to press the The vertical mechanical movement of the machine is converted into a lateral movement with a certain angle with the horizontal direction or with the horizontal direction, so as to meet the requirements of the side punching process. However, the wedge mechanism generates more heat, resulting in large energy loss, and thermal deformation will lead to lower punching accuracy; moreover, it is noisy and the working environment is noisy. Contents of the invention [0003] The invention discloses a hydraulic side punching device with low energy...
