Description

Technical Field

[0001] The utility model relates to the technical field, and particularly relates to an automatic polishing and wire drawing device for metal material processing. Background Technique

[0002] Polishing and wire drawing is a common metal surface treatment process. By using abrasives to perform reciprocating motion in the same direction on the surface of metal workpieces, the surface texture of metal workpieces is processed to produce regular and relatively uniform new textures. Common ones include fine stripe textures and circular textures, which can cover mechanical textures and die-casting defects in production. Therefore, an automatic polishing and wire drawing device for metal material processing is needed.

[0003] For example, the patent document CN210790396U discloses a polishing and wire drawing device, including: at least one polishing and wire drawing mechanism, and each polishing and wire drawing mechanism includes a polishing and wire drawing unit and a lifting drive unit; the polishing and wire drawing unit includes a polishing and wire drawing wheel, a main motor and a transmission member. The polishing and wire drawing wheel includes a wheel body and a central shaft driving the wheel body to rotate. The output shaft of the main motor drives the central shaft of the polishing and wire drawing wheel to rotate through a first transmission member; the lifting drive unit includes a substrate, a lifting motor arranged on the substrate and a lifting transmission assembly drivingly connected to the output shaft of the lifting motor. The lifting transmission assembly is fixedly connected to both the polishing and wire drawing wheel and the main motor. The lifting motor drives the lifting transmission assembly to move so as to drive the polishing and wire drawing wheel and the main motor to move synchronously in the vertical direction. However, there are still many deficiencies in this prior art. For example, it cannot automatically perform double-sided polishing and wire drawing treatment on metal materials. After the polishing and wire drawing treatment on one side of the metal material is completed, it is necessary to manually operate to turn over the metal material and re-perform the polishing and wire drawing treatment on the other side, which not only has low processing efficiency, but also has potential dangers when manually turning over the metal material.

A number of clamping cylinders are fixed on the upper end face of the upper clamping plate. The cylinder ends of the number of clamping cylinders are fixedly connected to the inner upper wall of the flipping box. A lower clamping plate is arranged in the middle of the lower pair of flipping conveyor belts. A number of clamping cylinders are fixed on the lower end face of the lower clamping plate.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0026] An automatic polishing and wire drawing device for metal material processing, such as Figure 1 , Figure 2 , Figure 6As shown in the figure, it includes two groups of racks 1. The two groups of racks 1 have the same structural functions and are used for polishing and wire drawing processing of different surfaces of metal materials. Two groups of polishing and wire drawing mechanisms 5 are provided on each group of racks 1. After one group of polishing and wire drawing mechanisms 5 performs polishing and wire drawing processing on the metal material, the other group of polishing and wire drawing mechanisms 5 can perform deburring processing on the surface of the metal material. The polishing and wire drawing mechanism 5 includes a polishing and wire drawing roller 501 and a tensioning roller 502. The polishing and wire drawing roller 501 is fixed inside the rack 1, and the tensioning roller 502 is suspended above the polishing and wire drawing roller 501. An abrasive belt 503 is sleeved on both the tensioning roller 502 and the polishing and wire drawing roller 501. Tensioning cylinders 508 are provided at both ends of the tensioning roller 502. The bottom end of the tensioning cylinder 508 is connected to a tensioning seat 509. Limiting grooves are opened at both ends of the tensioning seat 509. By adjusting a pair of tensioning cylinders 508 to change the height of the tensioning roller 502, the abrasive belt 503 moves along with the polishing and wire drawing roller 501 to complete the polishing and wire drawing processing of the metal material.

[0027] As Figure 3 shown, a polishing and wire drawing pulley 504 is fixed at the front end of the polishing and wire drawing roller 501. A polishing and wire drawing motor 505 is provided below the polishing and wire drawing pulley 504. The output end of the polishing and wire drawing motor 505 is fixedly connected with a driving pulley 506. A V-belt 9 is sleeved on both the driving pulley 506 and the polishing and wire drawing pulley 504. The polishing and wire drawing motor 505 is fixedly connected with an adjusting seat 507 below. The adjusting seat 507 is fixedly installed on the rack 1. The adjusting seat 507 can achieve the effect of tensioning the V-belt 9 by adjusting the height of the polishing and wire drawing motor 505 to ensure power transmission.

[0028] As Figure 2 、 Figure 3 shown, a plurality of pressing rollers 301 are provided on the feeding conveyor belt 3. Pressing adjustment frames 302 are provided at both ends of the plurality of pressing rollers 301. Pressing sliders 303 are slidably installed inside the pressing adjustment frames 302. A pressing adjustment bolt 304 is provided above the pressing slider 303. The pressing adjustment bolt 304 is threadedly connected to the pressing adjustment frame 302. By rotating the pressing adjustment bolt 304, the height of the pressing slider 303 is restricted, thereby restricting the height of the pressing roller 301. The pressing rollers 301 are arranged on both sides of the polishing and wire drawing roller 501 to ensure the smooth polishing and wire drawing of the metal material.

[0029] As Figure 1 、 Figure 2 shown, a moving frame 2 is slidably installed up and down inside the two groups of racks 1. A feeding conveyor belt 3 is installed inside the moving frame 2. Feeding cylinders 4 are respectively connected to the four corners at the lower end of the moving frame 2. The lower end of the feeding cylinder 4 is fixedly connected to the rack 1. By adjusting the height of the four feeding cylinders 4, the height of the feeding conveyor belt 3 and the polishing and wire drawing mechanism 5 is changed to adapt to the processing of metal materials of different specifications. After the polishing and wire drawing work is completed, the feeding conveyor belt 3 returns to the initial position to facilitate docking with the flipping conveyor mechanism 6 to complete subsequent processing.

[0030] As Figure 1 , Figure 2 , Figure 4 , Figure 8 shown, there is a flipping conveyor mechanism 6 between two groups of racks 1. The flipping conveyor mechanism 6 includes a flipping box 7 and a flipping bracket 8. At the upper end of the flipping bracket 8, two flipping shafts 801 are symmetrically and rotatably installed. The outer side wall of the flipping box 7 is fixedly connected to the inner sides of the two flipping shafts 801. On the outer sides of the two flipping shafts 801, flipping pulleys 802 are fixedly installed; the flipping brackets 8 commonly penetrate and rotatably install a transmission shaft 803. Both ends of the transmission shaft 803 are connected with transmission pulleys 804. The transmission pulleys 804 and the flipping pulleys 802 are commonly sleeved with a V-belt 9. The transmission pulleys 804 are driven by a motor to simultaneously transmit the power of one motor to the two flipping shafts 801 through the transmission shaft 803, reducing the number of motors used, ensuring uniform force when the flipping box 7 rotates, and stable flipping action. When the flipping box rotates 90 degrees, the lower end of the flipping box is higher than the transmission shaft, and there will be no collision between the flipping box and the transmission shaft.

[0031] As Figure 4 , Figure 5 shown, there are two pairs of upper and lower flipping conveyor belts 701 arranged inside the flipping box 7. There is a space between the two pairs of upper and lower flipping conveyor belts 701. In the middle of the upper pair of flipping conveyor belts 701, there is an upper clamping plate 702. On the upper end face of the upper clamping plate 702, a number of clamping cylinders 703 are fixed. The cylinder ends of the number of clamping cylinders 703 are fixedly connected to the inner upper wall of the flipping box 7. In the middle of the lower pair of flipping conveyor belts 701, there is a lower clamping plate 704. On the lower end face of the lower clamping plate 704, a number of clamping cylinders 703 are fixed. The cylinder ends of the number of clamping cylinders 703 are fixedly connected to the inner lower wall of the flipping box 7.

[0032] When the first embodiment works, a grinding belt 503 meeting the processing requirements is commonly sleeved outside the polishing and wire drawing roller 501 and the tensioning roller 502. The tensioning cylinder 508 is adjusted to make the grinding belt 503 reach the best tension and move along with the polishing and wire drawing roller 501. According to the specifications of the metal material to be processed, the height of the pressing roller 301 is adjusted. The metal material is placed on the feeding conveyor belt 3 inside the right rack 1. The feeding conveyor belt 3 drives the metal material upward to the processing height. After passing through the two groups of polishing and wire drawing mechanisms 5 in sequence to complete single-sided polishing, wire drawing and deburring processing, the feeding conveyor belt 3 returns to the initial height and docks with the flipping conveyor belt 701; the flipping conveyor belt 701 is turned on. After the metal material that has completed single-sided processing completely enters the flipping box 7, the clamping cylinders 703 are started, so that the upper clamping plate 702 and the lower clamping plate 704 cooperate to fix the position of the metal material. The motor is started to drive the flipping box 7 to rotate 180 degrees around the flipping shaft 801 through the transmission shaft 803 to complete the turning of the metal material. The clamping of the metal material is cancelled, and the flipped metal material is sent into the left rack 1 through the flipping conveyor belt 701 for polishing and wire drawing processing on the other side. Example 2

[0033] On the basis of Example 1, as Figure 4 , Figure 7 shown, two limiting blocks 601 are symmetrically installed on the outer wall of the flipping box 7, and two buffer blocks 602 are slidably installed in each of the two limiting blocks 601. The inner sides of the two buffer blocks 602 are fixedly connected by a spring 603.

[0034] In Example 2, when the flipping box 7 holds the metal material and flips it to the horizontal position, due to inertia, it will collide with the flipping bracket 8. After installing the limiting block 601 with the buffer block 602, the impact block 602 collides with the flipping bracket 8, and the vibration generated by the collision is absorbed by the spring 603, improving the clamping stability and avoiding damage to the metal material during the flipping process.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
