Description

Technical Field

[0001] This utility model belongs to the technical field of needle bending device, and in particular relates to a connecting rod needle bending device. Background Technology

[0002] Needle bending is a process of deforming and breaking the shape of the needle. Since the existing production process is often carried out manually, the needle bending dimensions are often not up to standard or the needle is bent at an angle after bending, which leads to poor subsequent testing or assembly. Further problems may even cause the needle to be damaged, resulting in product scrap and increased costs for enterprises. To address this, we propose a connecting rod needle bending device. Utility Model Content

[0003] This utility model provides a connecting rod bending device. After placing the product in the item positioning block, the switch is turned on, causing the front and rear cylinders and the bending foot fixing plate to move. Then, the bending die is used to bend the product, making it convenient for the operator to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a connecting rod bending needle device, comprising a base plate, on which supporting columns are symmetrically fixed, and an item positioning block is provided between the two sets of supporting columns. A guide rail fixed on a bending die is provided below the item positioning block, and a slider is slidably connected to the surface of the guide rail. A bending foot fixing plate is installed on the surface of the slider, and a bending die connecting rod is fixed at the front end of the bending foot fixing plate. A bending die is installed at the front end of the bending die connecting rod through a fixing pin. The middle part of the bending foot fixing plate is connected to a piston cylinder through a floating joint. A cylinder fixing plate is installed near the outer wall of the base plate, and front and rear cylinders are installed in the middle of the cylinder fixing plate. A guide post mounting plate is vertically installed at the front end of the bending foot fixing plate, and guide rods are symmetrically installed on the surface of the guide post mounting plate. A pressure plate is installed at the end of the guide rod. Springs are wound around the surface of each guide rod, and the two ends of the springs abut against the bending foot fixing plate and the pressure plate, respectively.

[0005] Furthermore, the item positioning block and the supporting column are combined to form a gantry frame.

[0006] Furthermore, the front end of the bending die is arc-shaped.

[0007] Furthermore, the top of the item positioning block is provided with two sets of slots that allow the curved mold to move freely.

[0008] Furthermore, the pressure plate and the item positioning block are parallel to each other.

[0009] The beneficial effects of this utility model are:

[0010] The connecting rod bending device is equipped with an item positioning block, front and rear cylinders, bending foot fixing plate, and bending mold. After the operator starts the switch, the front and rear cylinders and bending foot fixing plate move closer to each other, so that the pressure plate clamps the product. Then the pressure plate connecting block pushes the bending mold connecting rod to move, so that the bending mold connecting rod drives the bending mold to move. The bending mold bends the product. The needle is wrapped with wire and soldered before bending. The bending mechanism has high requirements. It needs to avoid the wire-wrapped part of the needle and bend it in place.

[0014] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings.

[0015] Example:

[0016] Please see Figure 1A connecting rod bending device includes a base plate 6. Support columns 8 are symmetrically threaded onto the surface of the base plate 6, and an item positioning block 2 is provided between the two sets of support columns 8. Below the item positioning block 2, a guide rail 7 is threaded onto a bending die 1, and a slider 11 is slidably connected to the surface of the guide rail 7. A bending foot fixing plate 15 is mounted on the surface of the slider 11, and a bending die connecting rod 14 is threaded onto the front end of the bending foot fixing plate 15. The bending die 1 is mounted on the front end of the bending die connecting rod 14 via a fixing pin. The middle of the bending foot fixing plate 15 is connected to a piston cylinder via a floating joint 12. A cylinder fixing plate 9 is installed near the outer wall of the base plate 6, and a front and rear cylinder 10 is threaded onto the middle of the cylinder fixing plate 9. A guide post mounting plate 5 is vertically threaded onto the front end of the bending foot fixing plate 15, and the guide post mounting plate 5 is... Guide rods 13 are symmetrically threaded on the surface of plate 5, and pressure plates 3 are threaded on the ends of guide rods 13. Springs 4 are wound around the surface of guide rods 13, and the two ends of springs 4 abut against the bent foot fixing plate 15 and pressure plates 3 respectively. When the operator uses the product 16, the operator places the product 16 on the item positioning block 2 and then turns on the switch. When the switch is turned on, the front and rear cylinders 10 move forward and drive the bent foot fixing plate 15 to move backward, so that the pressure plate 3 presses the product 16 with pressure. At the same time as pressing, the connecting block of the pressure plate 3 pushes the bending mold connecting rod 14 to move, so that the bending mold connecting rod 14 drives the bending mold 1 to start rotating. After the front and rear cylinders 10 move to the designated position, the bending mold 1 presses down to push the needle to bend, thus completing the forming.

[0017] In other embodiments, the item positioning block 2 and the support column 8 are combined to form a gantry. The gantry formed by the item positioning block 2 and the support column 8 increases the stability of the equipment during use and prevents the item positioning block 2 from shaking when the corner mold 1 squeezes the product 16 placed in the item positioning block 2. This also improves the stability of the corner mold 1 during the process of pressing down and bending the needle.

[0018] In other embodiments, the front end of the corner bend 1 is arc-shaped. When the corner bend 1 is pressed down to bend the needle, the corner bend 1 can avoid the part of the needle wrapped with thread, thus avoiding damage.

[0019] In other embodiments, the top of the item positioning block 2 is provided with two sets of slots that allow the corner mold 1 to move freely. When the corner mold 1 moves, the slots provided by the item positioning block 2 avoid the corner mold 1, allowing the corner mold 1 to move into place and increasing the accuracy of the corner mold 1 in bending the pins of the product 16.

[0020] In other embodiments, the pressure plate 3 and the item positioning block 2 are parallel to each other. By making the pressure plate 3 and the item positioning block 2 parallel to each other, it is convenient for the pressure plate 3 to push the product 16 placed on the item positioning block 2 to move.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
