Description

Technical Field

[0001] The invention relates to the technical field of light bulbs, in particular to a guide wire shaping machine for a C7 type stem. Background Art

[0002] C7 model bulbs are commonly used in mini refrigerator lights and indicator lights. The bulb is mainly composed of a filament, a glass shell, a lamp holder and a core column. The core column includes a guide wire, and the core column is used to support the guide wire. The guide wire of the C7 model bulb includes a long guide wire and a short guide wire. The long guide wire and the short guide wire are connected to the filament. Among them, the production technology requires that the filament is set vertically to ensure that the filament and the core column are in a straight line. It is necessary to shape the core column guide wire into a specific shape, especially the shape of the long guide wire, so as to ensure that the filament is centered and meets the luminous angle requirements. The applicant now designs a device that is convenient for shaping the core column guide wire. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems, and the technical solution adopted is:

[0004] A guide wire shaping machine for a C7 model light bulb stem comprises a base plate and a cylinder mounted on the base plate, wherein a movable mold mounting seat is mounted at one end of the base plate and a fixed mold mounting seat is mounted at the other end of the base plate, the cylinder is connected to the movable mold mounting seat, and a guide column is connected between the movable mold mounting seat and the fixed mold mounting seat; the inner side of the movable mold mounting seat is connected to the movable mold; the inner side of the fixed mold mounting seat is connected to a first fixed mold and a second fixed mold, and the right end of the fixed mold mounting seat is provided with a linkage device; the right end surface of the movable mold is provided with a convex edge, a first plane and a second plane from top to bottom, a first arc surface is provided between the convex edge and the first plane, and a second arc surface is provided between the first plane and the second plane; the left end surface of the first fixed mold is provided with a third plane, a third arc surface and a fourth plane from top to bottom; the linkage device comprises a connecting seat movably mounted at the end of the second guide column, a second movable mold is movably provided at one end of the connecting seat, the second movable mold extends into the first fixed mold, the first fixed mold is provided with a notch at the lower left corner, and the front end of the second movable mold is located in the notch.

[0005] A mold is created to match the C7 product's shape. The mold consists of two parts: the first fixed mold and the first movable mold. The nickel core wire is placed in the first fixed mold, and a pneumatic cylinder is used to push the first movable mold into a tight fit with the first fixed mold, shaping the core wire. The C7 core wire shaping ensures the filament is centered and meets the required lighting angle. The shape is then formed to ensure the filament and core are aligned, ensuring 360° illumination and uniform light.

[0006] Furthermore, the first fixed mold and the first movable mold are positioned facing each other.

[0007] Furthermore, the length of the first plane is equal to the length of the third plane, the arc length of the second arc surface is equal to the arc length of the third arc surface, and the length of the second plane is equal to the length of the fourth plane.

[0008] Ensure that the left end face of the first fixed die and the right end face of the first movable die are aligned. The left end face of the first fixed die and the right end face of the first movable die are consistent in shape. The shape of the extruded guidewire is consistent with the left end face of the first fixed die. This ensures that the shape requirements of the long guidewire are met.

[0009] Preferably, there is a gap between the first fixed mold and the second fixed mold.

[0010] Preferably, the convex edge and the first arc surface are located in the gap. The movable convex edge cooperates with the second fixed die to cut the long guide wire and shape the front end of the long guide wire into an inward bend.

[0011] Furthermore, the guide posts include a first guide post and a second guide post arranged diagonally opposite each other. The first guide post is located at the lower left corner of the first movable mold mounting base, and the second guide post is located at the upper right corner of the first movable mold mounting base. Movement of the fixed mold mounting base causes the first and second guide posts to move accordingly. Due to the linkage mechanism at the ends of the guide posts, the second movable mold moves in the opposite direction of the guide posts. Therefore, the first and second guide posts cannot be arranged on the same horizontal line.

[0012] To further describe, the first movable mold mounting seat can move from one end to the other end in a track formed by the first guide pillar and the second guide pillar.

[0013] Preferably, a connecting piece is connected to the middle position of the swinging piece, the swinging piece is rotatable on the connecting piece, and the connecting piece is fixed on the fixed mold mounting seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects: a mold that matches the shape of a guide wire product suitable for a C7 core column is produced, and the guide wire can be quickly and conveniently shaped into a specific shape.

DETAILED DESCRIPTION

[0022] The following further illustrates the embodiments of the present invention in conjunction with the accompanying drawings and implementation methods. The positional relationship described herein is consistent with the positional relationship direction of the accompanying drawings and is only for the convenience of description and does not limit the structure of the present invention.

[0023] In this embodiment, Figures 1 to 5As shown, the shaping machine comprises a base plate 1, a movable mold mounting base 4, and a fixed mold mounting base 8. A cylinder 2 is mounted on the base plate 1. The front end of the cylinder's piston rod is connected to the movable mold mounting base 4 via a cylinder connecting plate 3. Mounted on the other side of the movable mold mounting base is a first movable mold 5, which moves along with the movable mold mounting base in a linear reciprocating motion. Mounted on the movable mold mounting base 4 are two guide posts, a first guide post 6 and a second guide post 7, which guide the movable mold mounting base in its linear motion. The movable mold mounting base 4 is square in shape. The first and second guide posts are arranged diagonally, with the first guide post located at the lower left corner of the movable mold mounting base and the second guide post located at the upper right corner. A fixed mold mounting base 8 is mounted to the right of the first and second guide posts. The fixed mold mounting base is fixed to the base plate. A first and second fixed molds 9 and 90 are fixed to its inner side. A gap is formed between the first and second fixed molds 9 and 90. The lower left corner of the second fixed mold 90 is a right angle. The first fixed mold 9 and the first movable mold 5 are positioned opposite each other. As the first movable mold moves linearly to the right, the right end of the first movable mold abuts against the left end of the first fixed mold, causing the first movable mold to collide with the first fixed mold. The end of the second guide post is hingedly connected to a swinging member 11. The other end of this swinging member 11 is connected to a second pin, which is fitted with a connecting member. This connecting member connects to a second movable mold 12, which extends through the fixed mold mounting base and into the first movable mold. The other end of the connecting member does not contact the end of the first guide post. The middle of the connecting member is connected to a connecting member 13 via a rotating shaft, which is fixed to the fixed mold mounting base. A notch 14 is located in the lower left corner of the first fixed mold, and the front end of the second movable mold is located within this notch. When the first movable mold mounting base moves to the right, the first and second guide posts also move to the right (the second guide post acts like a guide rod). Due to the swinging member, one end of the connecting member swings rightward, while the other end swings leftward, driving the second movable mold to move leftward.

[0024] The right side of the first movable mold is provided with a convex edge 15, a first plane 16 and a second plane 17 from top to bottom. A first arc surface 18 is provided between the convex edge and the first plane, and a second arc surface 19 is provided between the first plane and the second plane. The left side of the first fixed mold is provided with a third plane 20, a third arc surface 21 and a fourth plane 22 from top to bottom. Figure 5As shown in the top view, the length of the first plane is equal to the length of the third plane, the arc length of the second arc surface is equal to the arc length of the third arc surface, and the length of the second plane is equal to the length of the fourth plane. The convex edge and the first arc surface are higher than the upper end of the first fixed mold. During the rightward movement of the first movable mold, the convex edge and the first arc surface enter the above-mentioned gap. The position where the fourth plane 22 is located extends to the right to form a cutting portion 23. The cutting portion 23 is a rectangle, and the upper right corner of the cutting portion 23 is a right angle. The lower left corner of the second movable mold 12 is also a right angle.

[0025] The working principle of the shaping machine:

[0026] The short guide wire 25 of the core column is placed in the above-mentioned notch, and the long guide wire 24 fits the left end face of the first fixed mold. The first movable mold moves to the right under the action of the cylinder, and the first movable mold squeezes the left side of the first fixed mold. The movement of the convex edge cooperates with the right-angled side of the lower left corner of the second fixed mold to cut off the front end of the long guide wire and bend it to the right at the same time. The remaining part of the long guide wire is shaped into a shape consistent with the right end face of the first movable mold. In the process of the first movable mold mounting seat moving to the right, the first guide column 6 and the second guide column 7 move to the right, causing the second movable mold to move to the left. The right-angled side of the cutting portion 23 cooperates with the right-angled side of the second movable mold 12 to cut the short guide wire. As shown Figure 6 The vertical long guide wire is pressed by the first movable mold into a specific shape that matches the guide wire of the C7 model bulb. The upper half of the long guide wire can lean against the filament, so that the filament and the stem are in a straight line, and the vertically arranged filament does not tilt, which would not meet the required lighting angle.

[0027] The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the scope of the present invention.
