Description

Technical Field

[0001] The invention belongs to the field of advanced manufacturing technology, and in particular relates to a stepless adjustment cutting machine for steel grating processing and a working method thereof. Background Art

[0002] Steel grating is an open steel structure composed of load-bearing flat steel and crossbars arranged orthogonally at regular intervals, secured by welding or compression locks. Crossbars are typically twisted square steel, but round steel or flat steel can also be used. Steel grating is primarily used for structural platform panels, trench covers, ladder treads, and building ceilings. Steel grating is typically made of carbon steel and hot-dip galvanized to prevent oxidation. Stainless steel can also be used. Steel grating offers ventilation, lighting, heat dissipation, anti-slip properties, and explosion-proof properties. To facilitate transportation, a conveyor system is required.

[0003] During the processing, steel gratings often need to be cut according to customer requirements. Most existing cutting equipment can only meet the cutting needs of a certain width and height, and the sizes of existing raceways are mostly fixed and cannot be adjusted. In the actual production process, due to different usage environments, the sizes and models of steel gratings required are also different. This leads to the need for enterprises to equip different processing equipment according to the production models, which leads to the need to purchase processing equipment of different sizes, which forces enterprises to increase the investment cost of equipment and also requires continuous expansion of factory land.

[0004] Most of the rolling ways of existing transport devices are integrally set up, which consumes a lot of processing materials and is relatively costly. At the same time, the steel grating will generate flames due to cutting during the processing, which can easily cause damage to the steel grating itself and cause adhesion problems, which will seriously affect the quality of product processing. Therefore, the existing transport devices need to be improved. Summary of the Invention

[0088] The working method of the stepless adjustment cutting machine described in this embodiment has the following specific steps: 1): first, the width of the conveying roller of the cutting machine is adjusted according to the size of the steel grating to be processed; that is, the spacing between the active transmission mechanism 125 and the driven transmission mechanism 126 is adjusted by the spacing adjustment driving mechanism 124, and the driven mechanism is driven to move synchronously by the active driving mechanism;

[0089] 2): The height of the supporting mechanism 24 is then adjusted. That is, the lifting drive mechanism 2451 drives the cylinder connecting plate 24511 to move, and the cylinder connecting plate 24511 drives the supporting plate lifting block 2453 to move. Driven by the supporting plate lifting block 2453, the third rack 2455 on the supporting plate lifting block 2453 and the synchronous gear 2456 on the lifting roller 2454 move relative to each other, thereby achieving the height adjustment of the supporting mechanism 24;

[0090] 3): Then place the steel grating to be processed on the conveyor roller, adjust the cutting device 13 to a suitable position, and cut the product through the cutting mechanism 133 according to production requirements.

[0091] In this embodiment, the specific method for the spacing adjustment drive mechanism 124 to adjust the spacing between the active transmission mechanism 125 and the driven transmission mechanism 126 is as follows: the driving motor 1242 drives the first driving wheel 1243 to rotate, and under the drive of the first driving wheel 1243, the first moving wheel 1244 moves along the second rack 1245. At the same time, during the rotation of the first moving wheel 1244, the transmission gear 1249 is driven, and the transmission rod 1248 is driven to rotate together by the rotation of the transmission gear 1249 at one end of the active driving mechanism. The transmission rod 1248 drives the transmission gear 1249 at one end of the total driving transmission mechanism 126 to rotate. Driven by the transmission gear 1249, the second moving wheel 1247 moves along the second rack 1245, so that the active driving mechanism drives the driven mechanism to move synchronously, thereby realizing the adjustment of the spacing between the active transmission mechanism 125 and the driven transmission mechanism 126.

[0092] The specific working method of the cutting device 13 in this embodiment is as follows:

[0093] Adjustment of the Y-axis direction of the cutting mechanism: the Y-axis driven driving mechanism is driven to move and rotate by the Y-axis active driving mechanism, that is, the Y-axis driving mechanism 1312 drives the Y-axis supporting seat 131 to move along the slide rail 113 through the sliding seat 1311, that is, the second motor 13121 drives the driving gear 13124 to rotate, and the Y-axis moving gear 13122 is driven to rotate by the driving gear 13124. Under the drive of the Y-axis moving gear 13122, the driven gear 13125 at one end of the second motor 13121 rotates along with it. When the driven gear 13125 rotates, it drives the driven gear 13125 at the other end to rotate together through the linkage shaft 13123. The driven gear 13125 away from the end of the second motor 13121 drives the Y-axis driven gear 13126 to rotate together, so that the Y-axis active driving mechanism drives the Y-axis driven driving mechanism to move synchronously on the first rack 114, thereby realizing the adjustment of the direction of the Y-axis;

[0094] Adjustment of the cutting mechanism in the X-axis direction: that is, the cutting mechanism 133 is driven to move left and right along the guide rail 1323 by the X-axis driving mechanism 1324. Specifically, the first motor 13241 drives the sliding bearing seat 13243 on the screw rod 13242 to move. Since the cutting mechanism 133 is connected to the sliding bearing seat 13243 via the nut seat, the cutting mechanism 133 is driven by the sliding bearing seat 13243 to move together, thereby adjusting the X-axis direction;

[0095] Z-axis direction adjustment: that is, the slider seat on the mounting plate is driven up and down by the cylinder. When the mounting plate moves up and down, the cutting assembly is driven up and down along the track, thereby realizing the adjustment of the Z-axis direction.

[0096] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
