Description

Technical Field

[0001] The utility model belongs to the technical field of powder metallurgy parts shaping, in particular to a shield support inner shape shaping die. Background Art

[0002] A shield is a special-shaped part used to protect cables. It is a one-piece structure consisting of a shield body with a first frame and a second frame on the left and right sides of the rear portion, respectively. Both the first and second frames are L-shaped, with connecting plates at their lower ends. Blocks are located on the left and right sides of the upper portion of the shield body. This shield is formed using powder metallurgy, and after sintering, it can produce dimensional defects. This means the dimension between the first and second frames does not meet the component's specifications, requiring reshaping to achieve acceptable dimensions.

[0003] The original shaping die is composed of two support blocks and a wedge-shaped punch. There is no assembly of the loose parts. During shaping, the punch and the two support blocks need to be put together and installed in the product, and then a press is used to press the punch to the bottom. It is not easy to operate and is prone to errors such as misplacement and wrong installation order, resulting in low efficiency.

[0004] Therefore, a shield support inner shape shaping die is urgently needed to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the existing technical problems and provide a shield support inner shape shaping die.

[0012] When the punch block moves downward, the wedge block pushes the first support block and the second support block to move oppositely; when the lower end face of the punch block contacts the upper end face of the base, the distance between the left side face of the first support block and the right side face of the second support block matches the standard size of the inner side face of the shield.

[0013] The shapes of the left side surface of the first supporting block and the right side surface of the second supporting block respectively match the shapes of the first frame and the second frame of the standard shield component.

[0014] Preferably, the left side of the wedge block is a left bevel, and the right side of the wedge block is a right bevel. The left bevel and the right bevel are symmetrically arranged, and the left bevel is inclined to point to the lower right.

[0018] The central angle corresponding to the arc groove is greater than 180°.

[0019] The central angle of the arc groove is greater than 180°, which is a superior arc. In this way, the width of the opening at the upper end of the arc groove is smaller than the diameter of the circle corresponding to the arc groove.

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0042] Example 1

[0043] like Figures 1 to 10 As shown, the shield support inner shape shaping die is used to shape the shield 1; the shaping die includes a support block and a punch; the shield is an integrated structure, including a shield body 2, and a first frame 3 and a second frame 4 are respectively provided on the left and right sides of the rear portion of the shield body; the first frame and the second frame are both L-shaped, and the lower ends of the first frame and the second frame are respectively provided with a connecting plate 5; the left and right sides of the upper portion of the shield body are respectively provided with a clamping block 6; the shaping die also includes a support block and a base;

[0044] The punch 7 is an integrated structure, including a wedge-shaped block 8 provided on its front end surface, and guide grooves 9 on the left and right sides of the wedge-shaped block;

[0045] The support block includes a first support block 10 and a second support block 11; the left side of the first support block matches the inner side of the first frame, and the right side of the second support block matches the inner side of the second frame; the rear end surfaces of the first support block and the second support block are both provided with guide protrusions 12; the lower end surfaces of the first support block and the second support block are both provided with sliders 13;

[0046] A support block 14 is fixedly provided above the punch; a slide groove 16 is provided on the front side of the upper end surface of the base 15;

[0047] The guide protrusions of the first support block and the second support block are respectively inserted into the guide grooves on the left and right sides; the sliders of the first support block and the second support block are both set in the slide grooves; the guide protrusions match the guide grooves and can slide up and down along the guide grooves; the sliders match the slide grooves and can move left and right along the slide grooves;

[0048] When the punch block moves downward, the wedge block pushes the first support block and the second support block to move oppositely; when the lower end face of the punch block contacts the upper end face of the base, the distance between the left side face of the first support block and the right side face of the second support block matches the standard size of the inner side face of the shield.

[0049] The left side of the wedge block is a left bevel 17, and the right side of the wedge block is a right bevel 18. The left bevel and the right bevel are symmetrically arranged, and the left bevel is tilted to point to the lower right;

[0050] The guide grooves on the left and right sides are parallel to the left inclined surface and the right inclined surface respectively;

[0051] The right end surface of the first supporting block and the left end surface of the second supporting block are parallel to and in contact with the left inclined surface and the right inclined surface respectively.

[0052] The slide groove is an arc-shaped groove, and the left and right ends of the slide groove pass through the left and right end surfaces of the base;

[0053] The central angle corresponding to the arc groove is greater than 180°.

[0054] The lower end surface of the support block is provided with a dovetail groove 19, and the upper end surface of the punch is provided with a dovetail insert 20 that matches the dovetail groove; the dovetail insert is inserted into the dovetail groove and fixedly connected to the support block.

[0055] Working principle:

[0056] When using this embodiment, after the shaping mold is assembled, the support block and the base are installed on the press through the shaping mold frame 21 (the installation here can adopt the existing technology and will not be described further here), and the position of the support block is aligned with the base. When the shaping mold is installed properly, the shaping can begin.

[0057] like Figure 11 As shown, the shaping die is fixed on the shaping die frame. In the natural state, the lower end face of the punch and the upper end face of the base are separated, and there is a gap between the two. At this time, the shield to be shaped is buckled at the corresponding position of the shaping die (outside the first support block and the second support block), and the shield is in a relaxed state.

[0058] like Figure 12 As shown, the press is driven downward to press the shaping die together, and the lower end face of the punch contacts the upper end face of the base. The punch block presses downward to drive the wedge block to push the first support block and the second support block to both sides, and support the inner shape of the shield (the first frame and the second frame) to a qualified state.

[0059] like Figure 13 As shown, the press moves upward and resets, the lower end face of the punch is separated from the upper end face of the base, the shaping die is separated, the punch block moves upward, and the two guide slides drive the first support block and the second support block to converge inward. At this time, the shield is relaxed and the shield is removed to complete the shaping.

[0060] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Any technical deformation made according to the technical solution of the present invention falls within the protection scope of the present invention.
