The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] like Figure 1 As shown, a forming needle shaping device includes a base plate 1, the bottom of a fixed base 5 is fixedly locked and mounted on the base plate 1 through four columns 4, and a control box 2 for controlling the sequential movement of pneumatic components is also installed on the rear end of the surface of the base plate 1.

[0020] In this embodiment, a movable cylinder 7 is provided at the top rear end of the fixed base 5, a cylinder fixing plate 6 is fixedly installed at the front end of the movable cylinder 7, the cylinder fixing plate 6 is fixedly locked on the fixed base 5, and an adjusting nut 8 with adjustable stroke is installed at the rear end of the movable cylinder 7.

[0021] In this embodiment, a main mold clamp 3 is provided at the top front end of the fixed base 5. The main mold clamp 3 mainly includes a left clamp 12 and a right clamp 13. The center of the left clamp 12 and the right clamp 13 is rotatably mounted on the fixed base 5. A group of movable bearings 15 are respectively installed at the tail ends of the left clamp 12 and the right clamp 13, and the bearings 15 are located in the V-shaped groove at the front end of the V-shaped block 10. The front ends of the left clamp 12 and the right clamp 13 are also connected together by a tension spring 14 to form an automatic reset structure.

[0022] In this embodiment, a V-block 10 is further provided between the mobile cylinder 7 and the main forming mold clamp 3. The tail of the V-block 10 abuts against the output end of the mobile cylinder 7 and is driven by the mobile cylinder 7 to move forward and backward, and the front V-shaped groove of the V-block 10 clamps the tail of the left clamping jaw 12 and the right clamping jaw 13. A push block 9 is fixedly installed at the rear end of the V-block 10. The push block 9 is located on the straight output path of the mobile cylinder 7. A pair of clamping blocks are symmetrically fixedly installed on both sides of the fixed base 5 to form a limiting groove 11. The V-block 10 is restricted in the limiting groove 11.

[0023] In this embodiment, a shaft core fixing base plate 16 is fixedly installed on the surface of the base plate 1 just below the main molding mold clamp 3, and a fixed shaft core 17 for fixing a skeleton 19 is fixedly installed on the shaft core fixing base plate 16, and the skeleton 19 is used to install the molding needle 18.

[0024] In actual use of the device, firstly, the forming needle 18 to be shaped is inserted into the corresponding frame 19, and then the middle hole of the frame 19 is manually sleeved on the fixed shaft core 17; then, the moving cylinder 7 is started through the control box 2, and the output end of the moving cylinder 7 moves to support the push block 9, thereby pushing the V-shaped block 10 forward through the push block 9. Since the V-shaped block 10 is restricted by the limit grooves 11 on both sides, it can only move horizontally in a straight line, and will not flip up when contacting the bearing 15; and in front of the V-shaped block 10, During the movement, the bearings 15 at the rear end of the left jaw 12 and the right jaw 13 move inward against the V-groove at the front end of the V-block 10. Based on the principle of leverage, the front ends of the left jaw 12 and the right jaw 13 gradually open, so that the molding needle 18 pre-stuck at the front ends of the two is opened, until the V-block 10 moves into place and the shaping is completed; at this time, the mobile cylinder 7 automatically retracts at the end of the stroke, and the left jaw 12 and the right jaw 13 are reset due to the elastic force of the tension spring 14, thereby completing a shaping. When it is necessary to adjust the shaping range of the molding needle 18, it is only necessary to adjust the adjusting nut 8 at the rear end of the mobile cylinder 7. By adjusting the position of the adjusting nut 8, the output stroke of the mobile cylinder 7 is controlled, and the forward movement of the V-block 10 is controlled, thereby controlling the opening and closing angles of the left jaw 12 and the right jaw 13, and then completing the shaping range, which is convenient for actual needs.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
