Background technique

With the rapid development of the automobile industry, people's quality requirements are constantly improving, and the market competition is fierce, so higher requirements are put forward for product manufacturing. We must have lower manufacturing costs, higher precision and better production stability to have more Strong market competitiveness, keeping pace with the development of the times. At present, in the production and processing of auto parts, the stamping process for forming the dual-mass flywheel sealing ring (see Figure 1 and 2 for the specific structure) is generally at least three processes of blanking, forming, and punching. The production process is many, and the cycle is long. Repeated positioning many times and often have problems such as unqualified punching position, resulting in high cost of parts production, poor production stability, and low production efficiency.

Contents of the invention

The purpose of the utility model is to solve the problems of low processing production efficiency of the existing dual-mass flywheel sealing ring, multiple positioning, affecting product processing quality and dimensional accuracy, and provide a composite forming mold for the dual-mass flywheel sealing ring.

The specific scheme of the utility model is: a double-mass flywheel sealing ring compound forming mold, which has an upper mold base and a lower mold base, and four sets of guide sleeves and guide columns are installed between the upper and lower mold bases. There are two pairs of stamping stroke limit columns; an upper template is installed below the upper die base, and a lower template is installed above the lower die base. There are blanking holes corresponding to the bolt holes of the workpiece on the periphery of the blanking forming holes of the lower template. A stripping plate is set outside the lower template, and two inner guide columns are installed on the lower mold base to match the stripping The material plate is guided, and a number of return springs are installed to reset the stripping plate; the spline hole punch A in the center of the workpiece and the bolt hole punch B corresponding to the blanking hole are hoisted under the upper template. The outer part of A is equipped with a forming template, which adopts several equal-height screws to slide and lift the upper template, and a number of compression springs are installed between the forming template and the upper template; The outer ring is formed and blanked.

The punch B, the punch A, the blanking concave template, and the forming template described in the utility model, their lower end working surfaces are in spatial positions, and there is a difference of a height h≥the workpiece thickness in the axial direction.

The height h=workpiece thickness+0.5mm mentioned in the utility model, wherein the distance between the lower working surface of the punch B and the top surface of the upper template is the shortest.

The upper surface of the lower template described in the utility model matches the design of the lower surface of the workpiece.

The lower end surface of the forming template described in the utility model matches the design of the upper surface of the workpiece.

The utility model completes the three processing procedures of blanking, forming and punching in one set of molds, which greatly improves production efficiency, reduces investment in mold equipment, reduces repositioning errors, improves product processing quality, and ensures product dimensional accuracy . In the utility model, the height difference design of the punch B, the punch A, the blanking concave template, and the forming template can be carried out, so that the mold can be pressed down step by step for processing, that is, the workpiece is formed as a whole→outer ring blanking forming→center The sequence of spline hole punching→bolt hole punching is stamped step by step, so that a punching machine with a smaller power can be used to save investment and reduce energy consumption.
