Description

Upper slide block device of punching machine and punching machine Technical Field The utility model relates to the technical field of stamping equipment, in particular to a punching machine upper sliding block device and a punching machine. Background Stamping line presses in the automotive industry use dies to process sheet materials into contoured body parts. The die main body is divided into an upper die and a lower die. In the stamping process, the press separates the upper die from the lower die. The lower die is fixed, and the upper die moves up and down along with the press machine to form a stamping process. In order to produce parts with different versions, the upper die is generally provided with a pneumatic part, and when part of the parts are produced, an air source is connected to the pneumatic part in the upper die to realize the switching of the working state of the upper die. In the prior art, an air source is communicated with an upper die in two general modes, one is that an air source interface is arranged on an upper sliding block, a group of soft air pipes are connected through the interface, the air pipes are communicated, and the upper die is communicated. The other is that the upper sliding block is not provided with an air source, and is changed from a lower working table of the press machine to an upper die by a group of air pipes. When the first mode is adopted for air pipe installation, the die is required to be opened into the press along with the workbench, then the press is pressed down to be attached to the die, the sliding block is clamped to clamp the die, the operation of the press is suspended, and then personnel can enter the press for operation. This process involves man-hour loss and risk of safety accidents during operation. The air pipe connected in the second mode moves up and down along with the upper sliding block and the upper die during punching operation, so that the risk of scraping other objects by the air pipe and the risk of collision with a conveying device of the in-out press exist in the process. Disclosure of utility model In order to solve the technical problems of safety risk and working hour loss of an upper die air pipe connecting structure in the prior art, the utility model provides the upper slide block device of the punching machine and the punching machine, an air channel of the upper slide block and an upper die is not needed to be manually connected, the installation efficiency is improved, the air channel is hidden in the upper slide block and the upper die to avoid scraping and touching external articles, running equipment and the like, and the safety risk is eliminated. In order to solve the technical problems, the technical scheme includes that the upper slide block device of the punching machine comprises an upper slide block, an upper die is detachably arranged on the bottom surface of the upper slide block, a pneumatic piece is arranged in the upper die, a first gas interface is arranged on the bottom surface of the upper slide block, a second gas interface is arranged on the upper surface of the upper die, the first gas interface is detachably connected with the second gas interface, a first air passage is arranged in the upper slide block, two ends of the first air passage are respectively connected with an external air source and the first gas interface, and the second gas interface is connected with the pneumatic piece through the second air passage. In this technical scheme, go up slider bottom surface demountable installation and go up the mould, the staff can dismantle and change the mould as required. The upper die is internally provided with a pneumatic piece for driving the upper die to be in a working state, and the pneumatic piece in the upper die can work normally only by being communicated with an air source. The upper surface of the upper die faces to an upper sliding block of the punching machine, a second gas interface is arranged on the surface, the bottom surface of the upper sliding block faces to the upper surface of the upper die, a first gas interface is arranged on the surface, and the second gas interface corresponds to the first gas interface in position in the vertical direction. In order to ensure normal operation of the stamping operation, the upper die needs to be fixed at a fixed position on the upper sliding block, so that the relative position between the first gas interface positioned on the upper sliding block and the second gas interface positioned on the upper die can be kept unchanged. When the upper slide block is arranged on the upper die, the upper die is only required to be placed at a determined position below the upper slide block, and the punching machine is controlled to drive the upper slide block to press the upper die. After the upper sliding block is pressed to the press-fit position between the upper sliding block and the upper die, the first gas interface is just connected with the se
