Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guide arm production equipment, in particular to a novel guide arm oblique-pressing and direct-pressing integrated molding machine. Background Art
[0002] like Figure 1-Figure 2 As shown, the guide arm is a typical multi-bend structure with several relatively many curved contours. When the guide arm is press-formed, because the pressing force is relatively large, the segmented curvature method is generally adopted, that is, multiple cylinders and mold groups are used to press the guide arm into the required contour shape section by section. The common form is generally to heat the workpiece as a whole to a temperature of 900°C, transfer it to the lower mold, and then use the three upper cylinders to press it down vertically in sections. The curved shape of the guide arm is constructed in advance on the lower mold, and the guide arm is pressed to the contour shape by the vertical cylinder. The guide arm has an upward warping requirement, such as Figure 1 As shown, a reverse (upper) cylinder mold set will be added.
[0003] This vertical pressing production method is not friendly to shapes with large bends. Figure 1 When pressing vertically downward on the first bend on the center left, the mold restricts the guide arm below. The vertical section between the first and second bends easily exceeds the metal's expansion range, causing scratches on the guide arm's surface, damaging the stress structure within it, or even breaking it. In this case, the produced guide arm will not meet service requirements or its service life will be greatly reduced.
[0004] Therefore, some manufacturers use Figure 2 In this way, another cylinder is added to the side. Cylinder 1 first presses down a short distance to make the guide arm bend to the range of cylinder 5, and then cylinder 5 is used to press from the side to bend it. This method will cause the frame of the molding equipment to become larger, the number of cylinders to increase, and the number of hydraulic and electrical control components to increase accordingly, which will significantly increase the equipment manufacturing cost and production cost.
[0005] Therefore, there is an urgent need to design a new guide arm oblique pressing and direct pressing integrated molding machine to solve the problems of poor production quality and high production cost of existing guide arms. Utility Model Content

[0018] The utility model has the following beneficial effects:
[0019] This innovative guide arm oblique and direct pressing integrated molding machine utilizes an angle adjustment mechanism. As the first vertical downward pressing die moves downward, the downward pressure, influenced by the side guides, transforms the combined downward pressure and lateral push force into a single oblique downward pressing force, pressing the guide arm into its curved contour. This reduces the tensile force that could cause deformation, allowing the guide arm to extend in an oblique downward direction under pressure, preventing stress imbalance and damage within the guide arm. This reduces costs and improves product quality and competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The working principle of the utility model:
[0047] As Figure 3 shown, a set of inclined pressing guide mechanism is added on the side surface of the frame 8, so that the first section of the vertical downward pressing die is inclined by 20 degrees under the influence of the side guide when moving downward.
[0048] The 20° oblique pressure guide mechanism's fixed base is mounted on the side wall of frame 8. A slider seat 1.3 is mounted on guide rail 1.7, sliding linearly along the dovetail guide rail.

This reduces the tensile force that would cause deformation of the guide arm 9, allowing it to extend diagonally downward under pressure, preventing stress imbalance within the guide arm 9 and potentially damaging it.
