Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire processing equipment, specifically to a shot blasting machine arm for preventing damage to wires. Background Technology
[0002] A shot blasting machine is a device that uses a high-speed rotating shot blaster to propel shot (such as steel shot or steel grit) with centrifugal force to strike the surface of a workpiece, thereby achieving surface cleaning, rust removal, oxide scale removal, and strengthening. Depending on the type of shot blasting machine and the characteristics of the workpiece to be cleaned, there are various workpiece conveying methods. Shot blasting machines for wire rods typically have a columnar arm structure, positioned laterally, whose main function is to support and fix the wire rod. When using existing shot blasting machines, the problem of damaging the wire rod often occurs. The main reason is that the shot blasting machine arm is usually made of hard metal materials (such as steel or aluminum), and because the wire rod tends to sway from side to side during transport into the shot blasting chamber, its surface is easily worn. Utility Model Content
[0003] This invention provides a shot blasting machine arm to prevent damage to wires, which can solve the technical problem that existing shot blasting machines easily damage the surface of wires.
[0004] This application provides the following technical solution:
[0005] A shot blasting machine arm for preventing wire damage includes: an arm column, comprising an arm column body and a flexible layer covering the outer surface of the arm column body, wherein the outer surface of the arm column body forms a plurality of annular grooves for placing wire, the annular grooves being eccentrically arranged and equally spaced; and partitions disposed on both sides of the arm column, the partitions comprising a partition body and a flexible layer covering the outer surface of the partition body.
[0006] Beneficial effects
[0007] 1. Reducing wire sway and protecting the wire surface: By installing baffles on both sides of the boom body and covering the outer surfaces of both the boom body and the baffles with a flexible layer, this design significantly reduces the lateral sway of the wire during transport into the shot blasting chamber. The flexible layer not only provides additional cushioning protection, preventing wear caused by direct contact between the wire and hard metal, but also absorbs impact forces, further protecting the wire surface from damage. This structural optimization ensures the integrity of the wire during processing and improves the yield rate.
[0008] 2. The annular groove features an eccentric design, allowing the wire to bounce during the rotation of the shot blasting arm. This enables the shot to more effectively enter and strike the inner ring of the wire, achieving comprehensive cleaning. Furthermore, the evenly spaced annular grooves ensure that all parts placed on the wire receive a uniform cleaning effect, preventing incomplete cleaning of certain areas due to insufficient shot contact. This not only improves cleaning quality but also ensures the consistency and stability of the production line, contributing to increased overall production efficiency and product quality.
[0009] In summary, this solution, by introducing partitions and flexible layers and optimizing the design of the annular groove, successfully solves the problem of damage caused by traditional shot blasting machine arms when processing wire. At the same time, it achieves a more efficient and comprehensive cleaning effect, which is of great significance for improving the quality of wire processing and production efficiency.
[0010] Furthermore, as an improvement, the two adjacent annular grooves are arranged in a mirror image with reference to the axis of the arm column.
[0011] Beneficial effects: It optimizes the dynamic balance and stability of the wire rod during shot blasting, reducing additional jumping or vibration caused by imbalance. This layout, by symmetrically distributing adjacent annular grooves, ensures uniform force distribution on the wire rod on the arm, avoiding the center of gravity shift problem that may be caused by eccentric arrangement. When the shot blasting arm rotates, the mirrored arrangement of the annular grooves makes the jumping of the wire rod more regular and stable, helping to expose different parts of the wire rod to the impact of the shot more evenly, thereby achieving a more thorough and consistent cleaning effect.
[0012] Furthermore, as an improvement, the partition and the arm column are fixedly connected in a detachable manner.
[0013] Beneficial effects: The modular design greatly enhances the flexibility and ease of maintenance of the equipment. This design allows for quick adjustment of the boom length according to actual production needs, adapting to the processing requirements of different wire sizes, thus improving the equipment's versatility and utilization. Simultaneously, the detachable connection facilitates the installation and replacement of the flexible layer covering the outer surface of the boom body and partition body, enabling maintenance work to be completed without complex tools or prolonged downtime, significantly reducing downtime and maintenance costs.
[0014] Furthermore, as an improvement, a keyway is formed on the arm column body, a flat key that transitions or clearances with the keyway is fixedly installed on the partition body, and a threaded hole penetrating the partition is formed on the partition body in a direction parallel to the axis of the arm column, and a bolt is threaded into the threaded hole.
[0015] Beneficial effects: It improves the stability and precision of the connection between the partition and the arm column, while maintaining ease of disassembly. The transition or clearance fit of the flat key not only ensures precise positioning between the partition and the arm column, preventing offset or wobbling due to assembly errors, but also enhances the overall structural rigidity and load-bearing capacity. The use of bolts further strengthens this connection method, ensuring stability even in high-intensity working environments and preventing loosening or detachment. The biggest highlight of this combined design is its balance between reliable fixation and ease of assembly and disassembly, allowing for quick and accurate assembly or disassembly operations, greatly facilitating maintenance and adjustment, and improving production efficiency and equipment maintainability.
[0016] Furthermore, as an improvement, the flexible layer is made of rubber.
[0017] Beneficial effects: The rubber material has good elasticity and flexibility, which can effectively buffer the hard impact between the wire and the arm or partition upon contact, reducing damage caused by direct friction. In addition, the high coefficient of friction of the rubber surface helps to increase the stability of the wire during processing, preventing it from slipping or accidentally shifting, and ensuring a smooth processing procedure.
[0018] Furthermore, as an improvement, the arm column body includes a steel core located at the center and an aluminum layer covering the outer surface of the steel core.
[0019] Beneficial effects: Combining the high strength of steel with the excellent thermal conductivity and lightweight properties of aluminum, this design enhances the overall structural strength of the boom column, improves heat dissipation efficiency, and reduces equipment weight. The steel core layer provides the necessary robustness and resistance to deformation, ensuring the stability and durability of the boom column during high-speed rotation and impact from shot. The outer aluminum layer, with its excellent thermal conductivity, effectively dissipates heat generated during operation, preventing overheating and damage to the wires or equipment itself. This also reduces overall weight, lowers the load on the drive unit, and contributes to energy conservation, reduced consumption, and improved operating efficiency. Attached Figure Description

[0024] Example 1
[0025] like Figure 1 , Figure 2 As shown, the shot blasting machine arm for preventing wire damage includes an arm column 100 and a partition plate 200 that are detachably fixedly connected. Both the arm column 100 and the partition plate 200 are configured in multiple modular designs. The specific structure and connection relationship are as follows:
[0026] The arm post 100 includes an arm post body 101 and a flexible layer 102. The arm post body 101 includes a steel core 103 located at the center and an aluminum layer 104 covering the outer surface of the steel core 103. Multiple annular grooves 105 for placing wires are formed on the outer surface of the arm post body 101. The annular grooves 105 are eccentric and equally spaced. Two adjacent annular grooves 105 are mirror images of each other with the axis 400 of the arm post 100 as a reference. The flexible layer 102 is made of rubber and covers the outer surface of the arm post body 101.
[0027] The partition 200 is disposed on both sides of the arm column 100. The partition 200 includes a partition body and a flexible layer 102. The flexible layer 102 is made of rubber and covers the outer surface of the partition body.
[0028] A keyway is made on the arm column body 101, and a flat key 106 that is fitted with or clearance fits the keyway is fixedly installed on the partition body. A threaded hole 107 that passes through the partition 200 is made on the partition body in a direction parallel to the axis of the arm column 100, and a bolt is threaded into the threaded hole 107.
[0029] The specific application process is as follows:
[0030] Before use, the arm column 100 and the partition plate 200 must be assembled. Specifically, the keyway on the arm column body 101 is inserted into the corresponding flat key 106 on the partition plate 200, and then bolts are used to pass through the partition plate 200 and the arm column 100 and fix them in place. After the shot blasting machine arm is assembled, an equal number of wires are evenly placed in several annular grooves 105, and then the drive mechanism 300 used to drive the shot blasting machine arm is started to send the wires into the shot blasting chamber for cleaning.
[0031] This solution, by introducing a partition 200, a flexible layer 102, and optimizing the design of the annular groove 105, successfully solves the problem of damage caused by traditional shot blasting machine arms when processing wire. At the same time, it achieves a more efficient and comprehensive cleaning effect, which is of great significance for improving the quality of wire processing and production efficiency.
