Description

Technical Field

[0001] This utility model relates to the technical field of cold heading devices, specifically a cold heading device for tightening injector caps. Background Technology

[0002] In the field of precision machinery manufacturing such as automobile engines and fuel systems, fuel injector caps, as key connecting parts, need to have high strength and high precision structural characteristics to ensure the sealing performance and working stability of the fuel injector. Cold heading process has become the mainstream processing method for fuel injector caps because it can retain metal flow lines and improve workpiece strength through plastic deformation.

[0003] During the cold heading process, the mold and cold steel material generate high temperatures during cutting, extrusion, and punching. This results in the workpiece being too hot after cold heading. If it is not cooled in time, the metal structure of the workpiece will still be unstable when it enters subsequent processes (such as secondary processing). It is prone to deformation under the extrusion of the equipment, leading to out-of-tolerance dimensional accuracy, surface damage, or even direct scrapping. This not only reduces the product qualification rate but also increases the waste of raw materials and production costs. To address the above problems, the inventor proposes a cold heading device for injector cap tightening to solve the above problems. Utility Model Content

A valve is provided on the connecting pipe 27 to control the opening and closing of the nozzles. The type, installation tilt angle, and number of nozzle groups 25 need to be selected according to actual usage requirements to ensure that all workpieces inside the receiving box 33 are sprayed. A material drop outlet is provided near the bottom on the side of the receiving box 33 away from the base platform 1. The collection box 31 is located on the side away from the base platform 1. The mounting box 31 is equipped with an installation block for easy installation of other conveying equipment or placement of a collection box. A water outlet pipe is located near the corner of the collection box 31 to facilitate the discharge of sprayed cleaning water. A transmission groove is located above the mounting box 4 to facilitate the second gear 46 driving the first gear 44. The collection box 31 is located inside the U-shaped load-bearing pipe 32, which serves as the load-bearing body. The collection box 33 will not touch the base platform 1 or the cold heading machine body 2 when it wobbles slightly.

It is worth noting that the cold heading machine body 2, the nozzle assembly 25, and the soft mudguard 37 in this design are readily available to those skilled in the art. The equipment purchased online has not undergone any structural modifications as described in this paper. Therefore, those skilled in the art are familiar with its working principles and can apply them proficiently based on their professional knowledge. Consequently, this paper will not elaborate further on these aspects. Furthermore, this solution aims to protect the physical structure, but does not provide protection for the circuitry and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0022] A short plate 35 is fixedly connected to the center of the bottom of the receiving box 33, and an auxiliary wheel 36 is rotatably connected to the side of the short plate 35 near the bottom.

[0023] By adopting the above technical solution, the side end of the short plate 35 is rotatably connected to the auxiliary rotating wheel 36 near the bottom by a pin. The auxiliary rotating wheel 36 is made of wear-resistant rubber material, which can reduce noise and wear when in contact with the eccentric wheel 43.

[0024] An installation box 4 is fixedly connected to the top center of the mounting base plate 3, and the installation box 4 is located at the center of the collection box 31. An installation block 41 is symmetrically fixedly connected to the top of the installation box 4 near the center, and a rotating shaft 42 is rotatably connected between the two installation blocks 41.

[0025] By adopting the above technical solution, the two mounting blocks 41 are rotatably connected to the rotating shaft 42 through the bearing, and the mounting box 4 is a rectangular box.

[0026] An eccentric wheel 43 is fixedly connected to the outer ring of the rotating shaft 42 near the center, and the eccentric wheel 43 cooperates with the auxiliary rotating wheel 36. A first gear 44 is fixedly connected to the outer ring of the rotating shaft 42 near the eccentric wheel 43.

[0027] By adopting the above technical solution, the outer periphery of the eccentric wheel 43 and the auxiliary rotating wheel 36 make rolling contact.

[0028] A motor 45 is provided on the inner wall of one side of the mounting box 4. A second gear 46 is fixedly connected to the output end of the motor 45, and the second gear 46 meshes with the first gear 44.

[0029] By adopting the above technical solution, the working motor 45 is started, causing the fixedly connected second gear 46 to rotate.

[0030] The bottom of the receiving box 33 is symmetrically and fixedly connected with soft mudguards 37 near the center.

[0031] By adopting the above technical solution, the soft mudguard 37 is made of soft material and its length is longer than the distance from the bottom of the receiving box 33 to the bottom of the collecting box 31, so that it can protect the mounting box 4 and the components above it when the receiving box 33 is moving.

[0032] A water storage tank 26 is fixedly connected to the side end of the main body 2 of the cold heading machine and above the discharge port 21.

[0033] By adopting the above technical solution, the water storage tank 26 is made of transparent acrylic material, which makes it easy to observe the water level. The top can be equipped with a water inlet and a vent hole as needed.

[0034] A connecting pipe 27 is fixedly connected to the bottom of the water storage tank 26, and the other end of the connecting pipe 27 is fixedly connected to multiple nozzle groups 25.

[0035] By adopting the above technical solution, the other end of the connecting pipe 27 is fixedly connected to multiple nozzle groups 25 through a diversion valve, and the diversion valve can adjust the water output of each nozzle group.

[0036] Working principle: When using this device, the processed nozzle caps can be discharged through the discharge port 21. Before operation, an appropriate amount of water needs to be added to the water storage tank 26. Then, when discharging the material, the valve body on the connecting pipe 27 is activated, and multiple nozzle groups 25 are used to rinse the material discharged below, thereby achieving a cooling effect and preventing the workpiece from being deformed due to collisions in subsequent processes if it is not cooled in time. The sprayed water will fall into the collection box 31 through the water outlet 34 and eventually be discharged outward (a protective cover can be installed on the top of the collection box 33 according to actual usage needs to prevent water from flowing through the outer wall of the collection box 33 to the components above the mounting box 4).

[0037] When spraying water, the motor 45 needs to be started, which causes the fixedly connected second gear 46 to drive the first gear 44 to rotate, thereby causing the rotating shaft 42 to rotate. Then, with the cooperation of the eccentric wheel 43 and the auxiliary rotating wheel 36, the receiving box 33 can be shaken under the action of the U-shaped load-bearing tube 32. Shaking the receiving box 33 (the amplitude of the shaking of the equipment will not cause large-scale scratches when dispersing the workpieces) can disperse the workpieces, avoid insufficient or excessive local cooling, and improve the overall cooling consistency.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
