Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a mold conveying device. Background Art

[0002] A stamping die is a deformation process equipment that processes materials into parts during cold stamping, and is called a cold stamping die. For feeding and stamping, the existing design uses a feeder to drive the material belt forward on the lower template of the stamping die, and then uses a hydraulic cylinder to drive the upper template downward to complete the stamping. The material belt is automatically controlled by the feeder and conventional detection pin electronic control software, and the action is completed under the written program. If the position of the material belt is slightly deviated, the forward position of the material belt is prone to errors. At this time, when the upper template moves down for stamping, unqualified finished products will be produced, and the mold will be damaged. In response to the above problems, combined with the structure of equidistant process notches on one side of the stamped material belt, we proposed a mold conveying device with an auxiliary positioning structure. Utility Model Content

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] Example 1

[0023] Reference Figures 1 to 6 A mold conveying device comprises a lower template 1 and a material belt 2 driven forward by a feeder, the top of the lower template 1 is fitted with the bottom of the material belt 2, the interior of the lower template 1 is provided with a waste bottom plate 15, one side of the material belt 2 is provided with process notches 4 at equal intervals, a forming sheet 3 is formed after the material belt 2 passes through the waste bottom plate 15, a right-angle notch 5 is provided at the connection between the material belt 2 and the forming sheet 3, a stop block 6 is fixedly connected to the top of the lower template 1, the stop block 6 is abutted against the inner side of the right-angle notch 5, a positioning block 8 and a pop-up component for driving the positioning block 8 to move are provided at the top of the lower template 1 and on one side of the material belt 2, one end of the positioning block 8 extends to the inside of the process notch 4, and anti-deviation components are provided at the top of the lower template 1 and on both sides of the material belt 2.

[0024] In the above technical solution, considering the problem that the position of the material belt 2 is prone to deviation, in order to solve such problems, the specific operation is as follows: the material belt 2 moves forward under the drive of the feeder, and then forms a molding sheet 3 after being punched by the upper template, and a right-angle notch 5 is formed at the junction of the last molding sheet 3 and the material belt 2, and the material belt 2 continues to move forward, and then the right-angle notch 5 abuts against the stop block 6, so that the material belt 2 cannot move forward, thereby preventing it from moving forward too far. At the same time, the positioning block 8 enters the process notch 4 under the action of the pop-up component, which can prevent the material belt 2 from retreating and causing deviation. Since the stop block 6 and the positioning block 8 are both purely mechanical structures, they are not prone to failure, which can improve the quality of the finished product and reduce the damage to the mold, making it more conducive to practical use.

[0025] Example 2

[0026] Reference Figure 5 The pop-up assembly includes a fixed block 7, which is fixedly connected to the top of the lower template 1, and a positioning block 8 is slidably connected to the inside of the fixed block 7. A circular groove 11 is provided at the other end of the positioning block 8, and a spring 10 is fixedly connected between the circular groove 11 and the inner wall of the fixed block 7. By setting the spring 10, when the material strip 2 moves forward, one end of the positioning block 8 abuts against one side of the material strip 2, and the spring 10 is in a compressed state. As the material strip 2 moves forward, the process notch 4 will move to the position of one end of the positioning block 8 so as to align with it, and then, under the elastic force of the spring 10, the positioning block 8 is pushed to slide from the inside of the fixed block 7, so that one end of it enters the inside of the process notch 4, thereby preventing the material strip 2 from moving backward. At the same time, one end of the spring 10 can enter the circular groove 11, thereby limiting the spring 10 and preventing it from detaching.

[0027] Reference Figure 5 , both sides of the fixed block 7 are provided with a slide groove 9, and the inside of the slide groove 9 is slidably connected with a slide post 12, and one end of the slide post 12 is fixedly connected to one side of the positioning block 8. By setting the slide groove 9 and the fixed block 7 that cooperate with each other, the positioning block 8 is pushed by the elastic force of the spring 10 to drive the slide post 12 to slide inside the slide groove 9, thereby guiding the positioning block 8 and preventing the positioning block 8 from being separated from the fixed block 7.

[0028] Reference Figures 1 to 3 , one end of the process notch 4 and the positioning block 8 are both trapezoidal structures, and the inclined surface at one end of the positioning block 8 abuts against the inclined surface of the inner wall of the process notch 4. By setting it as a trapezoidal structure, after the process notch 4 is aligned with the positioning block 8, the positioning block 8 enters the process notch 4, and the feeding direction is from the fixed block 7 to the forming sheet 3. At this time, the side of the positioning block 8 away from the inclined surface contacts one side of the inner wall of the process notch 4, and the two surfaces are perpendicular to the forward direction and parallel to each other, so that the material strip 2 cannot retreat. When the next step of stamping is performed, the material strip 2 moves forward directly, and the inclined surface of the inner wall of the process notch 4 slides with the inclined surface of one end of the positioning block 8, and the positioning block 8 moves toward the inside of the fixed block 7, thereby disengaging from the process notch 4, so that the advancement of the material strip 2 will not be blocked.

[0029] Reference Figure 6 The anti-deviating assembly includes a side-opening box 13, and two rollers 14 are rotatably connected inside the side-opening box 13. The outer wall of the roller 14 is covered with a rubber ring, and the rubber ring abuts against one side of the material belt 2. When the material belt 2 moves forward, the roller 14 rolls with one side of the material belt 2, and the rubber ring can reduce the friction on the material belt 2, so that the rollers 14 at both sides can guide the forward movement of the material belt 2 to prevent deviation.

[0030] Working principle: When in use, the material belt 2 moves forward driven by the feeder, and one end of the positioning block 8 abuts against one side of the material belt 2, and the spring 10 is in a compressed state. As the material belt 2 moves forward, the process notch 4 moves to the position of one end of the positioning block 8 to align with it, and then under the elastic force of the spring 10, the positioning block 8 is pushed to slide from the inside of the fixed block 7, so that one end of it enters the inside of the process notch 4; then the right-angle notch 5 abuts against the stop block 6, and then the punching machine drives the upper template to move down to complete the punching. After the punching is completed, the current right-angle notch 5 will be replaced by the forming piece 3, and a new right-angle notch 5 will be generated on the side close to the fixed block 7. When the next step of punching is performed, the material belt 2 moves forward directly, and the inclined surface of the inner wall of the process notch 4 slides with the inclined surface of one end of the positioning block 8, and the positioning block 8 moves toward the inside of the fixed block 7.

[0031] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
