[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model discloses a punch press protection device. Figure 1-4 A punch press protection device comprises a processing table 1, a support plate 2 is arranged on the upper rear side of the processing table 1, a hydraulic rod 3 is arranged on the upper end of the support plate 2, a punch head 4 is arranged on the bottom end of the hydraulic rod 3, a loading plate 5 and a protective cover 6 are arranged on the upper front side of the processing table 1, and the loading plate 5 is located on the inner side of the protective cover 6, a plurality of connecting blocks 7 are arranged on the right side of the protective cover 6, a positioning hole 8 is opened at the bottom end of the connecting block 7, and a positioning mechanism 9 used in conjunction with the positioning hole 8 is arranged on the right side of the bottom end of the processing table 1;

[0020] By adopting the above technical solution, when processing the workpiece, the protective cover 6 prevents the worker from contacting the punch head 4, and the chips during processing are not easy to splash everywhere, which greatly improves the safety during processing.

[0021] Reference Figure 2 The positioning mechanism 9 includes a T-shaped rod 901, a pull plate 902, two positioning rods 903 and a spring 904. The T-shaped rod 901 is arranged on the right side of the bottom end of the processing table 1. The pull plate 902 is slidably arranged on the T-shaped rod 901. The two positioning rods 903 are both arranged on the upper end of the pull plate 902. The top end of the positioning rod 903 passes through the processing table 1 and is plugged into the positioning hole 8. The spring 904 is sleeved on the outside of the T-shaped rod 901, and the two ends of the spring 904 are respectively connected to the pull plate 902 and the T-shaped rod 901.

[0022] By adopting the above technical solution, when the carrier plate 5 needs to be regularly maintained, the staff only needs to pull the pull plate 902 to drive the positioning rod 903 to move out of the positioning hole 8 on the connecting block 7, so as to quickly cancel the limit on the protective cover 6, and then pull the protective cover 6 to facilitate the disassembly and assembly of the protective cover 6, so as to facilitate the regular maintenance of the carrier plate 5 without affecting the normal processing of the workpiece.

[0023] Reference Figure 1 , Figure 3 and Figure 4 A plurality of slide grooves 10 are provided on the upper portion of the processing table 1 , and a plurality of sliders 11 are provided at the bottom end of the protective cover 6 . The bottom ends of the sliders 11 penetrate into the slide grooves 10 and are slidably connected with the slide grooves 10 .

[0024] By adopting the above technical solution, the sliding groove 10 and the sliding block 11 make it more convenient to pull the protective cover 6 for disassembly and assembly.

[0025] Reference Figure 4 An observation window 12 is provided on the front side of the protective cover 6 .

[0026] By adopting the above technical solution, the processing status of the workpiece can be easily observed through the observation window 12 when the workpiece is being processed.

[0027] Reference Figure 4 A first rectangular opening 13 is formed at the upper end of the protective cover 6 , and second rectangular openings 14 are formed at both the left and right sides of the protective cover 6 .

[0028] By adopting the above technical solution, the punch head 4 can be moved down into the protective cover 6 through the first rectangular opening 13, and then the workpiece can be conveniently inserted into the protective cover 6 for processing through the second rectangular opening 14.

[0029] Working principle: When the utility model is in use, the workpiece is first inserted into the protective cover 6 from the second rectangular opening 14 on the left, and the workpiece is located on the upper part of the carrier plate 5. Then the hydraulic rod 3 works to drive the punch head 4 to move downward to the inside of the protective cover 6 so that the workpiece can be processed. Then the workpiece is continued to be pushed to move, and continuous stamping processing can be performed on the workpiece. During the entire processing process, the protective cover 6 prevents the worker from contacting the punch head 4, which greatly improves the safety during processing. At the same time, the debris during processing is not easy to splash everywhere, which further improves the safety during work. Then, when the carrier plate 5 needs to be regularly maintained, the worker only needs to pull the pull plate 902 to drive the positioning rod 903 to move out of the positioning hole 8 on the connecting block 7, so as to quickly cancel the limit of the protective cover 6. Then, pulling the protective cover 6 can facilitate the disassembly and assembly of the protective cover 6, so that the carrier plate 5 can be easily maintained regularly without affecting the normal processing of the workpiece.

[0030] When the utility model is in use, the protective cover 6 is arranged on the workpiece so that the worker will not contact with the punch head 4 when processing the workpiece, and the debris during processing is not easy to splash everywhere, thus greatly improving the safety during processing.
