Description

Technical Field

[0001] This utility model relates to the field of aluminum product surface treatment technology, and in particular to a device for wire drawing treatment of the outer surface of aluminum products. Background Technology

[0002] Wire drawing is a process that creates a wire-like texture on the surface of aluminum products through physical and mechanical methods. Currently, there are automatic wire drawing machines and manual wire drawing machines. Although automatic wire drawing machines are more efficient, they are equipped with advanced automated control systems, high-precision transmission devices, and complex mechanical structures. These advanced components and technologies make their manufacturing costs high. Therefore, some manufacturers still use manual wire drawing machines.

[0003] However, manual wire drawing machines require manual pressing of the abrasive belt to contact the workpiece during operation. The belt is then driven by the transmission system to draw the surface of the workpiece. However, the drawing effect depends on the operator's experience and technique. Different operators or the same operator at different times may apply inconsistent pressure, especially for workpieces of varying thicknesses and with different gaps between the workpiece and the abrasive belt. Operators cannot accurately guarantee the pressure applied to the belt, resulting in variations in the coarseness, depth, and uniformity of the drawn texture, leading to poor product quality stability. Based on the above, it is necessary to design a wire drawing device for the outer surface of aluminum products to solve these problems. Utility Model Content

[0004] This utility model provides a device for wire drawing treatment of the outer surface of aluminum products, in order to solve the problems existing in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A device for surface wire drawing of aluminum products includes a wire drawing machine body. A sliding plate located below an abrasive belt is slidably connected to the wire drawing machine body. The sliding plate is used to drive the workpiece to move below the abrasive belt. The device also includes a pressure block for pressing down the abrasive belt to perform wire drawing on the surface of the workpiece. The wire drawing machine body is further provided with a limiting mechanism for limiting the descent height of the pressure block according to the height of the workpiece. The limiting mechanism includes a sliding rod on the wire drawing machine body and a limiting seat threadedly connected to the sliding rod. A connecting piece slidably connected to the sliding rod is connected to the pressure block. When the pressure block drives the connecting piece to abut against the limiting seat, the position of the pressure block is limited.

[0007] Preferably, a calibration element is also movably sleeved on the slide rod, and the calibration element is located between the limiting seat and the connecting element.

[0008] Preferably, a first spring is connected between the upper end of the connector and the slide rod.

[0009] Preferably, the slide plate is provided with a positioning mechanism for positioning the workpiece, the positioning mechanism including a clamping plate slidably connected to the slide plate and a second spring disposed between the clamping plate and the slide plate.

[0010] Preferably, the pressure block is equipped with a dust suction hood, which is connected to an external negative pressure adsorption device via a suction hose.

[0011] Preferably, the pressure block is connected to a handle for operating the pressure block.

[0012] The beneficial effects of this utility model are as follows: when the pressure block is pressed down, the limiting seat limits the connecting parts, restricting the further pressing stroke of the pressure block. At this time, the pressure block will press the sanding belt against the workpiece surface with a relatively fixed pressure. The position of the limiting seat is adjusted according to the height of the workpiece to determine the pressing position of the pressure block, so that the sanding belt can adhere to the workpiece surface with appropriate pressure, achieve uniform contact, and improve the wire drawing effect on the workpiece surface.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-4 As shown, an aluminum product surface wire drawing treatment device includes a wire drawing machine body 1 and a dust suction hood. A sliding plate 12 located below the sanding belt 11 is slidably connected to the wire drawing machine body 1. The dust suction hood sliding plate 12 is used to drive the workpiece to move below the sanding belt 11. The sanding belt 11 can be installed on the sanding belt 11 wheel of the wire drawing machine body 1. It usually has one driving wheel and one or more driven wheels. The driving wheel is driven to rotate by a motor through a transmission device (such as a belt, gear, etc.). The driven wheels play the role of supporting and tensioning the sanding belt 11, so that the sanding belt 11 maintains a certain tension. When the motor starts, the driving wheel starts to rotate. Due to the friction between the sanding belt 11 and the driving wheel, the driving wheel will drive the sanding belt 11 to move along its circumference. The abrasive belt 11 forms a closed loop between the driving wheel and the driven wheel. At the same time, the pressure block 13 device is used to press the abrasive belt 11 downward so that the abrasive belt 11 comes into contact with the surface of the aluminum product and moves relative to it. Under pressure, the abrasive grains of the abrasive belt 11 generate friction on the aluminum surface, thus realizing the wire drawing operation of the workpiece. However, when performing manual wire drawing, the pressure block 13 is usually pressed down by hand. However, due to the different heights of the workpieces, the pressure block 13 cannot maintain a uniform downward pressure on the abrasive belt 11. Therefore, this solution also provides a limiting mechanism on the main body 1 of the wire drawing machine to limit the descent height of the pressure block 13 according to the height of the workpiece.

[0021] Specifically, the limiting mechanism includes a slide rod 2 mounted on the main body 1 of the wire drawing machine and a limiting seat 21 threadedly connected to the slide rod 2. A connecting piece 3, which is slidably connected to the slide rod 2, is attached to the dust collection hood pressure block 13. Both the connecting piece 3 and the slide rod 2 can be multiple. When the pressure block 13 is pressed down, it moves vertically under the guidance of the slide rod 2 to press the sanding belt 11. The position of the limiting seat 21 on the slide rod 2 can be adjusted according to the height of the workpiece to limit the downward pressure position of the pressure block 13. Furthermore, when the dust collection hood pressure block 13 drives the connecting piece 3... When in contact with the limiting seat 21, the position of the pressure block 13 is limited, so that the position of the limiting seat 21 can be adjusted according to the different heights of the workpiece, and the pressure block 13 will not move arbitrarily, maintaining the uniformity of wire drawing. In order to facilitate the adjustment of the limiting seat 21, the limiting seat 21 can preferably be set on the side closer to the operator, as shown in the figure. One or two can be set, and it is not necessary to set the limiting seat 21 on each slide rod 2. When two limiting seats 21 are set and adjusted, the height positions of the two limiting seats 21 need to be adjusted to be consistent.

[0022] Reference Figure 4As shown, furthermore, a calibration component 4 is movably sleeved on the slide rod 2. The dust suction hood calibration component 4 is located between the limiting seat 21 and the connecting component 3. The calibration component 4 can be in the form of a thin plate. When the workpiece is placed on the slide plate 12, the calibration component 4 is rotated to move towards the workpiece so that the calibration component 4 is aligned with the upper end face of the workpiece. Then, the limiting seat 21 is rotated to move below the calibration component 4. When performing wire drawing, the calibration component 4 is rotated at a certain angle to move it away from the workpiece. The calibration component 4 can also be used to easily adjust the height of multiple limiting seats 21 to the same height.

[0023] Among them, the upper end of the connector 3 is connected to the slide rod 2 by a first spring 5. When no force is applied to the pressure block 13, the pressure block 13 can be driven to move upward under the action of the first spring 5, so that it is away from the sanding belt 11 when it is not performing wire drawing operation.

[0024] Reference Figure 3 As shown, in order to reduce the risk of hand injury caused by accidental slippage of the hand onto the sanding belt 11, a handle 8 is provided on the pressure block 13 for operating the pressure block 13. By holding the handle 8 and pressing down on the pressure block 13, the hand is kept away from the sanding belt 11.

[0025] Reference Figure 4 As shown, the vacuum hood slide plate 12 is further provided with a positioning mechanism for positioning the workpiece. The vacuum hood positioning mechanism includes a clamping plate 6 slidably connected to the slide plate 12 and a second spring 61 disposed between the clamping plate 6 and the slide plate 12. When the workpiece is placed on the slide plate 12, the clamping plate 6 is driven by the elastic force of the second spring 61 to clamp and position the workpiece, so that the workpiece will not move randomly during the wire drawing operation, thus ensuring the wire drawing quality.

[0026] Reference Figure 4 As shown, a large amount of debris is generated during the grinding and wire drawing process. If it is not cleaned up in time, it will be scattered on the workbench and around the equipment, affecting the cleanliness of the working environment. Therefore, a dust suction hood 7 is provided on the pressure block 13. The dust suction hood 7 is connected to an external negative pressure adsorption device, such as an industrial vacuum cleaner, through a suction hose 71. The negative pressure principle is used to suck the debris generated by grinding into the pipe and then collect it into the dust collection bag or dust collection bucket of the external vacuum cleaner, effectively collecting some of the debris, reducing the flying of debris in the air, and improving the working environment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
