[0021] In order to further explain the technical scheme of the utility model, the following specific embodiments are described in detail.

[0022] Please refer to Figure 1 The utility model provides a punch device for handle processing, including frame 1, punch machine body 2, shaft 3, punching table 4 and splash protection device 5, frame 1 upper front is equipped with punch machine body 2, and the bottom of punch machine body 2 is provided with shaft 3, and frame 1 lower front is equipped with punching table 4, and frame 1 front is provided with splash protection device 5.

[0023] Please refer to Figures 2-5 The utility model provides a punch device for handle processing, and splash protection device 5 includes guide rail 51, protective cover 52, mesh 53, guide rod 54, sliding sleeve 55, return spring 56, shaft sleeve 57 and connecting frame 58, frame 1 both sides are equipped with guide rail 51, and protective cover 52 is sleeved on the outside of frame 1, and frame 1 is slidably connected with protective cover 52 through guide rail 51, and the front of protective cover 52 is paved with mesh 53, and the operator can pass through mesh 53 to check the processing condition, and the left and right sides in the protective cover 52 are longitudinally installed with guide rod 54, and sliding sleeve 55 is slidably sleeved on the surface of guide rod 54, and return spring 56 is sleeved on the surface of guide rod 54, and the bottom of return spring 56 is fixedly sleeved with guide rod 54, and the top of return spring 56 is fixedly sleeved with sliding sleeve 55, and return spring 56 provides the elastic force of downward for protective cover 52, so as to ensure that protective cover 52 can be tightly pressed on punching table 4, and shaft sleeve 57 is fixedly installed on the surface of shaft 3, and connecting frame 58 is symmetrically installed on the left and right sides of shaft sleeve 57, and the tail end of connecting frame 58 is fixedly installed with sliding sleeve 55, so as to establish the transmission connection of protective cover 52 and shaft 3, when shaft 3 executes the punching action, protective cover 52 also synchronously moves downward with shaft 3 and is shielded on the outside of punching table 4, can protect the operator from being hurt by the waste chips accidentally splashed in the punching process, effectively improve safety, and protective cover 52 is controlled to move by shaft 3, need not additional power source and controller, convenient to use.

[0024] Further explanation, the area ratio of mesh 53 on the front of protective cover 52 is not less than 60%, so that mesh 53 can provide a good field of view for the operator.

[0025] Further explanation, the one-way stroke of sliding sleeve 55 along guide rod 54 is greater than or equal to 10cm, which can reserve enough extension length for protective cover 52 to ensure safety.

[0026] Further explanation, the connecting frame 58 and the sliding sleeve 55 and the shaft sleeve 57 are connected in a detachable manner, and can be connected by bolts or other connection methods, so that the connecting frame 58 can be detached alone, thereby releasing the transmission connection between the protective cover 52 and the shaft 3, and enabling the protective cover 52 to be manually adjusted in position, thereby providing more use modes, and enabling the user to assemble it according to the use requirements.

[0027] Further explanation, the positioning bolt 59 is spirally installed in the side screw hole of the protective cover 52, and can be screwed into the inner side of the protective cover 52 and abut against the guide rail 51, thereby achieving the friction locking of the protective cover 52.

[0028] Further explanation, the shock pad 510 with a thickness of ≥2mm is laid on the bottom edge of the protective cover 52, and serves as a buffer between the protective cover 52 and the punching table 4, thereby avoiding the abnormal noise caused by the collision between the protective cover 52 and the punching table 4.

[0029] The working principle is as follows:

[0030] First, when performing the punching operation, the handle base is first fixed on the top of the punching table 4, and then the punching machine body 2 is started, so that the punching machine body 2 drives the shaft 3 to perform the punching action on the handle base below.

[0031] Second, the splash-proof protection device 5 is arranged at the front of the machine frame 1, and in the punching process, since the protective cover 52 is in transmission connection with the shaft 3 through the connecting frame 58, the protective cover 52 will move together with the shaft 3, and when the shaft 3 performs the punching action, the protective cover 52 will also be lowered synchronously with the shaft 3 to shield outside the punching table 4, thereby protecting the operator from being injured by the accidental splashing of the debris in the punching process, effectively improving the safety, and the protective cover 52 is controlled to move by the shaft 3, without the need for an additional power source and controller, thereby being convenient to use, and the protective cover 52 and the shaft 3 are in elastic sliding connection, so that when the protective cover 52 is parked on the top of the punching table 4, the shaft 3 can still be continuously pressed to complete the punching, without affecting the normal operation of the shaft 3.

[0032] Third, the positioning bolt 59 is arranged at the side of the protective cover 52, and in use, the connecting frame 58 can be detached alone, thereby releasing the transmission connection between the protective cover 52 and the shaft 3, so that the protective cover 52 is manually adjusted in position, and after the position adjustment of the protective cover 52, the positioning bolt 59 is tightened for friction locking, so that the protective cover 52 can be locked at a specific height position, thereby providing more use modes for the protective cover 52, and enabling the user to assemble it according to the use requirements.

[0033] The above is only a preferred example of the present application and is not used to limit the present application, although the present application is described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features therein can be replaced equivalently.
