The mold frame 1 comprises two parallel side plates 101. The top and bottom of the side plate 101 are provided with a top plate 102 and a bottom plate 103 respectively. The top plate 102, the bottom plate 103 and the two side plates 101 form a containing space for containing the stamping die 2. The containing space is open at both ends. The top plate 102 and the bottom plate 103 are parallel to each other and perpendicular to the side plate 101. The connection mode of the top plate 102 and the two side plates 101 can be welding, bolt connection or clamping. In this embodiment, the connection mode of the top plate 102 and the side plate 101 is clamping and bolt connection. The top and bottom of the side plate 101 is provided with a mounting groove for containing the end of the top plate 102 and the bottom plate 103. In this embodiment, the mounting groove comprises a first groove and a second groove. Specifically, the top of the two side plates 101 is provided with a first groove open to the containing space on the side facing the containing space. The two ends of the top plate 102 correspondingly extend into the two first grooves and are connected by bolts. The connection mode of the bottom plate 103 and the two side plates 101 can be welding, bolt connection or clamping. In this embodiment, the connection mode of the bottom plate 103 and the two side plates 101 is clamping, that is, the bottom of the two side plates 101 is provided with a second groove open to the containing space on the side facing the containing space. The two ends of the bottom plate 103 correspondingly extend into the two second grooves and are connected by bolts. The side plate 101, the top plate 102 and the bottom plate 103 are fixedly connected in this connection mode, which can improve the bearing capacity of the entire mold frame 1 and further improve the stability of the mold frame 1.

[0023] The outer side of at least one side plate 101 is fixedly provided with a power connecting block 7, and the power connecting block 7 is driven to reciprocate by a driving source. In the embodiment, the outer side of each of the two side plates 101 is fixedly connected with a power connecting block 7. The power connecting block 7 is connected with the side plate 101 in a bolted manner. The driving source is a lead screw or a cylinder, which can drive the power connecting block 7 to reciprocate, thereby driving the die frame 1 to move, achieving the position adjustment of the stamping mechanism, and further enabling the stamping mechanism to be flexibly combined to stamp the steel plates of different sizes and shapes.

[0024] The top plate 102 is provided with a hydraulic cylinder 3 for pushing the stamping die 2 to close, and a limiting assembly for limiting the stroke of the hydraulic cylinder 3. The limiting assembly includes a sensing plate 4 that moves synchronously with the piston rod of the hydraulic cylinder 3, and two sensors 5 that can sense the position of the sensing plate 4. The two sensors 5 are distributed along the movement direction of the piston rod. In the embodiment, the shell of the hydraulic cylinder 3 is fixed above the top plate 102, and the free end of the piston rod of the hydraulic cylinder 3 penetrates through the top plate 102 and is located below the top plate 102. The hydraulic cylinder 3 is connected with the top plate 102 in a bolted manner. Thus, the stroke of the hydraulic cylinder 3 is limited. Figure 1 and Figure 2 As shown in the figures, the sensing plate 4 is located above the top plate 102, that is, a slide rod 401 is slidably arranged on the top plate 102. The slide rod 401 has a cylindrical structure, and a hole with the same diameter as the slide rod 401 is formed in the top plate 102. The slide rod 401 penetrates through the hole and has two ends located on the two sides of the top plate 102, respectively. Specifically, the top end of the slide rod 401 is located above the top plate 102 and is fixedly connected with the sensing plate 4. The sensing plate 4 has a circular plate structure coaxial with the slide rod 401, and the two are connected by a bolt located at the center of the sensing plate 4. The bottom end of the slide rod 401 is located below the top plate 102 and is connected with the piston rod. In the embodiment, the bottom end of the slide rod 401 is fixedly connected with a moving plate 301. The moving plate 301 has a circular plate structure coaxial with the slide rod 401. The diameter of the moving plate 301 is the same as that of the sensing plate 4, and the moving plate 301 is connected with the slide rod 401 by a bolt located on the axis of the two. A push plate 403 is fixedly sleeved on the piston rod. The moving plate 301 is located below the push plate 403 and on the movement track of the push plate 403, that is, the edge of the push plate 403 extends into the space between the upper surface of the moving plate 301 and the lower surface of the top plate 102. When the hydraulic cylinder 3 pushes the stamping die 2 to close, the piston rod moves downward to push the push plate 403 to move the moving plate 301 downward.

[0025] The sensor 5 is arranged above the top plate 102 and at one side of the induction plate 4, and is connected to the top plate 102 through the fixing sheet 6. Specifically, the fixing sheet 6 comprises a vertical part perpendicular to the top plate 102 and a horizontal part parallel to the top plate 102, and the vertical part is integrally connected with the horizontal part. The horizontal part is connected to the top plate 102 by bolting. A long hole 601 is formed in the vertical part, and the length direction of the long hole 601 is parallel to the movement direction of the piston rod. The sensor 5 is slidingly arranged in the long hole 601 and can be fixed. When the piston rod moves downward to push the stamping die 2 to close, the push plate 403 pushes the moving plate 301 to move downward, and then drives the induction plate 4 to move downward until the induction plate 4 is sensed by the lower sensor 5, that is, the lower sensor 5 senses the induction plate 4 and transmits the sensing signal to the control unit. The control unit controls the piston rod to stop pushing the stamping die 2 and move upward. Under the action of the spring 402 recovering the elastic force, the induction plate 4 moves upward until the induction plate 4 moves to the position of the upper sensor 5. The upper sensor 5 senses the induction plate 4 and transmits the sensing signal to the control unit. The control unit controls the piston rod to change the movement direction, that is, the arrangement of the sensor 5 is used to control the stroke of the piston rod. The arrangement of the long hole 601 can adjust the positions of the two sensors 5, and then adjust the stroke of the hydraulic cylinder 3, so that the hydraulic cylinder 3 can adapt to different stamping dies 2, and the application range of the utility model is improved.

[0026] An open-end material passing groove 105 is formed in the side wall of the die frame 1, and the opening direction of the material passing groove 105 is the same as that of one opening direction of the accommodating space. During the stamping of the steel plate, the steel plate near the edge passes through the material passing groove 105 and moves along the plate conveying direction. In the embodiment, the material passing groove 105 is formed in the two side plates 101, and the positions and opening directions of the material passing grooves 105 on the two side plates 101 are the same, so that the material passing grooves 105 on the two side plates 101 are connected. The material guide plate 104 is fixedly arranged on the side wall of the material passing groove 105, and the two sides of the material guide plate 104 are bent downward to form bent parts. The two bent parts are located at the two sides of the side plate 101, so that the steel plate can pass through the material passing groove 105.

[0027] A plurality of mounting holes 106 for mounting the stamping die 2 are formed in the bottom plate 103. In the embodiment, the number of the mounting holes 106 is three and they are uniformly distributed along the plate conveying direction. An inner thread is formed in the middle mounting hole 106. The stamping die 2 is pushed into the accommodating space, and the lower die plate of the stamping die 2 is connected to the middle mounting hole 106 by bolting. The positioning pins are inserted into the two mounting holes 106 at the edges. The outer side wall of the positioning pin is in close contact with the side wall of the lower die plate of the stamping die 2, so that the positioning and fixing of the stamping die 2 are realized.

[0028] The bottom plate 103 is provided with a discharging hole 107 corresponding to the blanking hole of the stamping die 2, and the size of the discharging hole 107 is larger than that of the blanking hole, so that when different stamping dies 2 are installed, the discharging hole 107 is always communicated with the blanking hole, and the punched waste can smoothly pass through the blanking hole and the discharging hole 107.
