Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, and specifically relates to a deburring device for the edges of steel template production. Background Technology

[0002] The deburring device for steel formwork production edges is a specialized piece of equipment designed to eliminate burrs generated on the edges of steel formwork after cutting or stamping. It uses a conveyor belt or chain transport mechanism as a carrying platform to ensure that the steel formwork is transported smoothly to the processing area. It is equipped with grinding components such as abrasive wheels and grinding wheels, and performs fine processing on the edges through high-speed rotation. Depending on production needs and cost considerations, its grinding method can be divided into double-sided grinding and single-sided grinding.

[0003] In existing steel template production edge deburring devices, when using single-sided grinding, the longitudinal load is applied only by the pressure roller above the conveyor belt, but there is a lack of lateral constraint on the steel plate. The steel plate is subjected to the coupling effect of the tangential friction force of the grinding wheel / sand belt and the traction force of the conveyor belt, which easily causes lateral instability, resulting in uneven burr removal, local residue, and may also lead to the safety hazard of the workpiece slipping out of the processing area. Utility Model Content

[0004] The purpose of this utility model is to provide a deburring device for the edges of steel templates. An adjustable push plate makes the roller press against the steel template on the conveyor belt, thus confining the steel template between the sanding belt and the push plate, preventing lateral displacement and slippage, reducing safety hazards, and avoiding burr residue on the edges of the steel template after grinding, thereby improving the grinding quality.

[0005] The specific technical solution adopted by this utility model is as follows: A steel formwork production edge deburring device includes a conveyor belt with a transmission assembly on a grinding machine. The top of the conveyor belt is offset with a plurality of push plates for laterally constraining the steel formwork. The push plates are Y-shaped and both ends are fixedly connected to a horizontal plate. The horizontal plate is provided with several through slots that are equidistantly offset along the axial direction, and a support shaft is provided in the corresponding slot. A roller is rotatably sleeved on the outside of the support shaft, and the roller achieves its own axial displacement through an internal elastic compensation mechanism.

[0006] The elastic compensation mechanism includes journal rings that are symmetrically arranged on the outer wall of the support shaft and integrally formed. A disc spring is fitted between the two journal rings.

[0007] Inner pressure ring plates are fixedly connected to both ends of the inner wall of the roller; Furthermore, the inner pressure plate is located at both ends of the disc spring.

[0008] A bridge plate is fixedly connected to the top of the horizontal plate; One end of each of the aforementioned support shafts is fixedly connected to the bridge plate.

[0009] A plurality of locking blocks corresponding to and matching the push plate are fixedly provided on one side of the conveyor belt; The locking block has a scale bar on its side wall.

[0010] Both the locking block and the push plate have through slots in the middle. The two slots are connected by fasteners to form a detachable fixed connection.

[0011] The diameter of the inner pressure plate is smaller than the outer diameter of the disc spring; The diameter of the journal ring is larger than the inner diameter of the disc spring.

[0012] The technical effect achieved by this utility model is as follows: the adjustable push plate makes the roller press against the steel template on the conveyor belt, so that the steel template is restricted between the sand belt and the push plate, preventing it from shifting laterally and slipping off, reducing safety hazards, thereby avoiding burr residue on the edge of the steel template after grinding and improving grinding quality.

Detailed Implementation

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-3As shown, a deburring device for steel formwork production includes a conveyor belt 101 mounted on a grinding machine 1. Several push plates 2 for laterally constraining the steel formwork are offset at the top of the conveyor belt 101. The push plates 2 are Y-shaped, with horizontal plates 201 fixedly connected to both ends. Several through slots 208 are equidistantly offset along the axial direction on the horizontal plates 201. Support shafts 203 are correspondingly provided within the through slots 208. Rollers 206 are rotatably sleeved on the outer side of the support shafts 203. The rollers 206 achieve axial displacement through an internal elastic compensation mechanism. The elastic compensation mechanism includes journal rings 204 symmetrically arranged on the outer wall of the support shafts 203 and integrally formed. Disc springs 205 are sleeved between two journal rings 204. Inner pressure ring plates 207 are fixedly connected to both ends of the inner wall of roller 206, and the inner pressure ring plates 207 are located at both ends of disc spring 205; a bridge plate 202 is fixedly connected to the top of the horizontal plate 201, and one end of several support shafts 203 is fixedly connected to the bridge plate 202; several locking blocks 102 corresponding to and matching the push plate 2 are fixedly provided on one side of the conveyor belt 101; the side wall of the locking block 102 is provided with a scale strip 103; the middle of the locking block 102 and the push plate 2 are both provided with through grooves 104; the two through grooves 104 are connected by fasteners 209 to form a detachable fixed connection; the diameter of the inner pressure ring plate 207 is smaller than the outer ring diameter of the disc spring 205, and the diameter of the journal ring 204 is larger than the inner ring diameter of the disc spring 205.

[0017] According to the above structure, the pressure between the push plate 2 and the locking block 102 is increased or decreased by tightening or loosening the nuts of the fastener 209, thereby adjusting the position of the push plate 2 to adapt to steel templates of different widths. The fastener 209 can be added or removed according to actual needs, but there must be at least one. At the same time, the displacement distance of the push plate 2 is recorded and judged by the scale bar 103 to keep the displacement distance of several push plates 2 consistent. The specific number of "several" push plates 2 and locking blocks 102 can be selected according to the equipment size of the grinding machine 1 and the length of the conveyor belt 101 in actual production. Furthermore, by adjusting the position of the push plate 2, the roller 206 is made to fit against the side of the steel template. When the conveyor belt 101 moves the steel template, the roller 206 also rotates to reduce friction. The support shaft 203 provides support for the roller 206 through its fixed connection with the bridge plate 202. The through groove 208 provides space for the roller 206 to accommodate and rotate. The specific number of "several" rollers 206 is preferably 4-5. Furthermore, the roller 206 also allows for limited axial displacement during rotation to disperse stress and reduce wear. Specifically, the roller 206 achieves axial adaptive adjustment through the elastic extension and contraction of the disc spring 205. When not in operation, the disc spring 205 is in a natural compressed state, and the inner pressure ring plate 207 is close to both ends of the disc spring 205 to form an initial positive pressure. When the conveyor belt 101 drives the steel template close to the roller 206, the cross plate 201 restricts its lateral displacement, and the edge of the steel template presses against the roller 206 to overcome the resistance of the disc spring 205 and cause the roller 206 to move upward along the support shaft 203. The steel template may produce slight undulations due to differences in thickness / straightness, etc. At this time, the roller 206 fits in real time through the flexible deformation of the disc spring 205. Furthermore, regarding the lubrication and wear of the elastic roller 206, there are many mature and common designs in the industry, but for the convenience of technical personnel, a brief explanation is provided here: In this embodiment, the support shaft 203 is fixed and stationary, and the disc spring 205 only undergoes periodic compression / rebound along the axial direction of the support shaft 203. It mainly bears radial loads rather than torque, and there is no displacement in the circumferential direction, resulting in low wear. The main components, such as the support shaft 203 and the roller 206, can be made of materials similar to precipitation-hardened stainless steel, which are corrosion-resistant and wear-resistant. Their surfaces can also be coated with a coating similar to diamond carbon film (DLC) to reduce friction through self-lubrication. Alternatively, high-temperature high-speed bearing grease can be selected for lubrication on the contact surfaces of the support shaft 203 and the inner hole of the roller 206, and the journal ring 204 and the disc spring 205, etc., all of which can effectively increase slip and reduce wear.

[0018] The working principle of this utility model is as follows: By tightening or loosening the nut of the fastener 209, the degree of clamping between the push plate 2 and the locking block 102 can be precisely increased or decreased, thereby finely adjusting the position of the push plate 2 to adapt to steel templates of different widths. The fastener 209 can be flexibly added or removed according to actual needs, but at least one must be retained. At the same time, the displacement distance of the push plate 2 is recorded and judged in real time with the help of the scale bar 103 to ensure that the displacement of multiple push plates 2 is consistent. Furthermore, the support shaft 203 is firmly connected to the bridge plate 202 to provide stable support for the roller 206, while the through groove 208 provides the roller 206 with a space to accommodate it and a degree of freedom of rotation. The number of rollers 206 is preferably set to 4-5. During rotation, the roller 206 is allowed limited axial displacement to disperse stress and reduce the risk of wear. Furthermore, specifically, the axial adaptive adjustment of the roller 206 is achieved through the elastic extension and contraction of the disc spring 205: when not in operation, the disc spring 205 is in a naturally compressed state, and the inner pressure ring plate 207 is tightly attached to its two ends to form an initial positive pressure; when the conveyor belt 101 drives the steel template close to the roller 206, the cross plate 201 restricts the lateral displacement of the steel template, and the edge of the steel template presses against the roller 206, overcoming the resistance of the disc spring 205, forcing the roller 206 to move upward along the support shaft 203; if the steel template has slight undulations due to differences in thickness or straightness, the roller 206 can fit in real time through the flexible deformation of the disc spring 205; Furthermore, regarding lubrication and wear issues, there are already mature designs in the industry. To facilitate understanding by technical personnel, an example is provided below: In this solution, if the support shaft 203 is fixed and stationary, the disc spring 205 only undergoes periodic compression / rebound along the axial direction of the support shaft 203. It mainly bears radial loads rather than torque and has no displacement in the circumferential direction, resulting in low wear. Major components such as the support shaft 203 and the roller 206 can be made of precipitation-hardening stainless steel to improve corrosion resistance and wear resistance. The surface can be coated with a diamond carbon film (DLC) coating to achieve self-lubrication. At the same time, high-temperature high-speed bearing grease can be applied to key parts such as the inner hole of the support shaft 203 and the roller 206, and the contact surface of the journal ring 204 and the disc spring 205 to effectively reduce friction loss and extend the service life of the components.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
