Detailed ways

The implementation of the present invention will be illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

As shown in Figure 1, Figure 2, and Figure 3, the present invention discloses a horizontal punching device with a mandrel, including a device frame, a punching assembly, and a waste cleaning assembly.

The device frame includes a rectangular horizontal bottom plate 1, a mandrel fixing plate 2, a guide post 3, an oblique brake fixing plate 4, an oblique brake 5, a mold handle fixing plate 6, and a mold handle 7. A mandrel fixing plate 2 is vertically fixed on the long side edge of the bottom plate 1, and guide posts 3 are respectively fixedly installed on the upper surfaces of the two ends of the mandrel fixing plate 2, and an oblique brake fixing plate 4 parallel to the bottom plate 1 is arranged directly above the guide posts 3 , oblique brake fixed plate 4 lower surface two ends are fixedly installed with oblique brake 5 respectively, and oblique brake fixed plate 4 upper surface is fixedly connected with mold handle fixed plate 6, and vertically is fixed with mold handle 7 on the mold handle fixed plate 6.

The punching assembly includes two identical guide rails 8, two identical oblique brake punch sliders 9, a large punch 10, and a small punch 11. The two guide rails 8 are respectively installed on the upper surface of the bottom plate 1 along the long side of the bottom plate 1. At both ends of the central axis, the two oblique brake punch sliders 9 are installed on the two guide rails 8 and on the same vertical plane as the two oblique brakes 5, and the large punch 10 and the small punch 11 are respectively installed on the two guide rails. On the opposite surface of the two oblique brake punch sliders 9, the punching assembly also includes a spring 14, and the two ends of the spring 14 are respectively connected to the opposite surfaces of the two oblique brake punch sliders 9, thereby utilizing the elasticity of the spring 14 to Reset the two oblique brake punch sliders 9 after the punching is completed; mandrel limit blocks 15 are vertically installed on the opposite surfaces of the two guide rails 8, and a core bar is arranged between the two mandrel limit blocks 15. Rod 16, mandrel 16 is horizontally fixed on mandrel fixing plate 2, utilize mandrel stop block 15 to carry out positioning while, can also avoid the situation that big and small punches collide because of slide block moving stroke is too large.

Clear waste assembly comprises cylinder 12 and the cylinder fixed plate 13 of band through hole, and cylinder fixed plate 13 is vertically installed on the short side edge of bottom plate 1 by small punch 11 one end, and cylinder 12 is horizontally installed on cylinder fixed plate 13 and cylinder 12 One end of the piston rod passes through the through hole of the cylinder fixed plate 13 and is at the side position of the punch slide block 9 of the oblique brake.

As a further optimization of the present invention, as shown in FIG. 4 , a long positioning plate 17 perpendicular to the long side of the bottom plate 1 is fixed on the edge of the bottom plate 1 at a position opposite to the mandrel fixing plate 2 .

The operation process of the band mandrel horizontal punching device of the present invention is as follows. At first, the mandrel 16 is installed and fixed on the mandrel fixing plate 2, and the hole of the mandrel 16 is opposite to the large punch 10 and the small punch 11. The pipe fitting of punching is enclosed within on the mandrel 16, utilizes strip positioning plate 17 to locate. After the preparation is completed, start the press to drive the mold handle 7 to press down, so the inclined brake fixing plate 4 drives the inclined brake 5 to snap into the inclined brake punch slider 9, so that the inclined brake punch slider 9 moves quickly to the middle position, greatly The punch 10 and the small punch 11 carry out horizontal punching to the pipe fittings under the drive of the inclined brake punch slide block 9 .
