Description

Technical Field

[0001] This utility model relates to the field of curved beams, and in particular to a processing device for curved beams. Background Technology

[0002] Concrete curved beams are a type of structural component widely used in construction engineering. They typically utilize the curved shape and overlapping of reinforced concrete, through the fabrication and fixing of formwork structures, followed by the laying of pre-embedded steel bars in the erected formwork and the pouring of concrete, and finally curing, thus forming the corresponding structure.

[0003] In many fields such as construction and machining, the curved beam bending machine is a crucial piece of equipment. It is mainly used to bend beams of various materials into specific curved shapes to meet the needs of different projects. In concrete structures, under the action of bending moment, the tension zone of the member needs steel bars to bear the tensile force. For curved beams, the stress state under load is more complex. By bending the steel bars into a shape that matches the curve of the beam, the steel bars can better exert their tensile properties, effectively resist the tensile force generated by bending, and work together with the concrete to improve the bending resistance of the beam and ensure the safety and stability of the structure.

[0004] When a concrete curved beam is bent, its bending components undergo high-intensity mechanical motion. During the bending process, the interaction between the curved beam and the bending die may generate metal shavings, sparks, and other flying debris. These flying debris have a certain speed and energy and may splash into the operator's eyes, face, or other parts of the body, causing eye injuries or skin abrasions. This makes the bending machine dangerous to operate. To address this issue, a processing device for curved beams is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a processing device for curved beams, which aims to improve the interaction between curved beams and bending dies in the prior art. This interaction may generate metal shavings, sparks and other flying debris. These flying debris have a certain speed and energy and may fly into the operator's eyes, face and other parts, causing eye injuries or skin abrasions, thus causing certain dangers when the bending machine is in operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A processing device for curved beams includes a bending machine body. Two sets of protective covers are provided on the top of the bending machine body. The bottom of the protective covers contacts the top of the bending machine body. Fixing blocks are fixedly installed on the front and rear sides of both sides of the bending machine body. The inner side of the fixing blocks and the outer side of the protective covers are rotatably installed. A through groove is opened on the outer side of the protective covers. A limiting component for limiting the protective covers is provided on the top of the protective covers.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes two sets of mounting plates. The bottom of the mounting plates and the top of one set of protective covers are fixedly installed. The inner side of the mounting plates is provided with slots. The top of the other set of protective covers is provided with two sets of inserts. The inserts are inserted into the slots.

[0010] As a further description of the above technical solution:

[0011] A connecting block is fixedly installed on the inner side of the insert block, and an electric push rod is fixedly installed on the top of another set of protective covers. The telescopic end of the electric push rod and the right side of one set of connecting blocks are fixedly installed.

[0012] As a further description of the above technical solution:

[0013] The top of the other set of protective covers is rotatably mounted with gears, and the top of the other set of protective covers is provided with two sets of toothed plates. The toothed plates mesh with the gears, and rubber pads are fixedly mounted on the outer side of the toothed plates. The outer side of the rubber pads contacts the inner side of the connecting block.

[0014] As a further description of the above technical solution:

[0015] Another set of protective covers has a protective box fixedly installed on its top. The outer side of the insert block extends through to the outer side of the protective box and is slidably installed with the protective box. A spring is fixedly installed on the outer side of the connecting block. The outer side of the spring is fixedly installed with the inner wall of the protective box.

[0016] As a further description of the above technical solution:

[0017] The top of the protective box is provided with a glass plate, the bottom of the glass plate is in contact with the top of the protective box, and the four corners of the top of the glass plate are detachably installed to the top of the protective box by screws.

[0018] As a further description of the above technical solution:

[0019] Each set of toothed plates has a limiting block fixedly installed at the bottom, and one set of protective covers has two sets of limiting grooves at the top, with the limiting block and limiting grooves being slidably installed.

[0020] This utility model has the following beneficial effects:

[0021] In this invention, through the cooperation of the mounting plate, slot, and insert, when the arc beam is inserted into the top of the bending machine body to prepare for bending, the protective cover can be rotated inward at the same time. When the bottom of the protective cover contacts the top of the bending machine body, the bottom of the mounting plate will contact the top of another set of mounting plates. Then, the insert can be pushed outward. The insert moves outward and enters the slot, thereby limiting the position of the insert.

[0022] In this invention, the protective box and the spring work together to allow the toothed plate to reset. At this time, the spring will apply pressure to the connecting block, which will cause the insert block and the slot to disengage. Then, the iron filings and other debris on the top of the bending machine body can be cleaned. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5This utility model provides an embodiment of a processing device for curved beams, including a bending machine body 1. Two sets of protective covers 2 are provided on the top of the bending machine body 1, with the bottom of the protective covers 2 contacting the top of the bending machine body 1. Fixing blocks 3 are fixedly installed on the front and rear sides of both sides of the bending machine body 1, with the inner side of the fixing blocks 3 rotatably installed on the outer side of the protective covers 2. A through groove 4 is provided on the outer side of the protective covers 2, and a limiting component 5 for limiting the protective covers 2 is provided on the top of the protective covers 2. First, the curved beam to be bent can be placed on the top of the bending machine body 1. Then, the protective covers 2 can be rotated inwards simultaneously. When the bottom of the protective covers 2 contacts the top of the bending machine body 1, the two sets of protective covers 2 can be limited by the limiting component 5. Next, the bending machine body 1 can be started to bend the curved beam. Finally, the bent curved beam can be placed in a template, and concrete can be poured into the template and allowed to cool naturally before use.

[0032] Reference Figure 1-5The limiting component 5 includes two sets of mounting plates 51. The bottom of the mounting plates 51 and the top of one set of protective covers 2 are fixedly installed. The inner side of the mounting plate 51 is provided with a slot 52. The top of the other set of protective covers 2 is provided with two sets of inserts 53. The inserts 53 and the slots 52 are inserted into each other. Through the cooperation of the mounting plates 51, slots 52 and inserts 53, when the arc beam is inserted into the top of the bending machine body 1 to prepare for bending, the protective cover 2 can be rotated inward at the same time. When the bottom of the protective cover 2 contacts the top of the bending machine body 1... At this time, the bottom of the mounting plate 51 will contact the top of another set of mounting plates 51. Then, the insert block 53 can be pushed outward. The insert block 53 moves outward and enters the slot 52, thereby limiting the insertion block 53. A connecting block 54 is fixedly installed on the inner side of the insert block 53. An electric push rod 55 is fixedly installed on the top of another set of protective covers 2. The telescopic end of the electric push rod 55 is fixedly installed on the right side of one of the connecting blocks 54. Through the cooperation of the connecting block 54 and the electric push rod 55, the electric push rod 55 can be activated. When the connecting block 54 moves outward, the insert block 53 moves outward, and the insert block 53 moves outward and enters the slot 52, thereby limiting the mounting plate 51 and preventing the protective cover 2 from shaking. A gear 56 is rotatably mounted on the top of another set of protective covers 2, and two sets of toothed plates 57 are provided on the top of the other set of protective covers 2. The toothed plates 57 mesh with the gear 56, and a rubber pad 58 is fixedly mounted on the outer side of the toothed plates 57. The outer side of the rubber pad 58 and the inner side of the connecting block 54 are connected. Upon contact, through the interaction of gear 56, toothed plate 57, and rubber pad 58, the electric push rod 55 will drive a set of connecting blocks 54 to move to the left. At this time, the connecting block 54 will drive one set of toothed plates 57 to move to the right. The movement of toothed plates 57 to the right will drive gear 56 to rotate. The rotation of gear 56 will drive another set of toothed plates 57 to rotate to the left. The movement of toothed plates 57 will drive another set of connecting blocks 54 and insert blocks 53 to move to the left, thereby simultaneously moving insert blocks 53 outward, thus limiting the two sets of protective covers 2.

[0033] Reference Figure 1-5Another set of protective covers 2 has a protective box 59 fixedly installed on its top. The outer side of the insert block 53 extends through to the outer side of the protective box 59 and slides with the protective box 59. A spring 510 is fixedly installed on the outer side of the connecting block 54. The outer side of the spring 510 is fixedly installed with the inner wall of the protective box 59. Through the cooperation of the protective box 59 and the spring 510, when the toothed plate 57 is reset, the spring 510 will apply pressure to the connecting block 54, thereby causing the insert block 53 to disengage from the slot 52. Then, the iron filings and other debris on the top of the bending machine body 1 can be cleaned. A glass plate 6 is provided on the top of the protective box 59. The bottom contacts the top of the protective box 59. The four corners of the top of the glass plate 6 are detachably installed to the top of the protective box 59 by screws. The glass plate 6 can be installed so that the bolts on the glass plate 6 can be removed, thereby replacing the damaged gear 56 and tooth plate 57. The bottom of each set of tooth plates 57 is fixedly installed with a limit block 7. The top of one set of protective covers 2 is provided with two sets of limit grooves 8. The limit block 7 and the limit groove 8 are slidably installed. Through the mutual cooperation of the limit block 7 and the limit groove 8, the tooth plate 57 can be limited to prevent the tooth plate 57 from shaking, thereby preventing the gear 56 from meshing with the tooth plate 57.

[0034] Working principle: Before the curved beam is placed on the formwork, the protective cover 2 can be rotated inward by the handle. When the bottom of the protective cover 2 contacts the top of the bending machine body 1, the electric push rod 55 can be activated. The telescopic end of the electric push rod 55 will drive a set of connecting blocks 54 to move to the left. At this time, the connecting block 54 will drive one set of toothed plates 57 to move to the right. The toothed plate 57 moving to the right will drive the gear 56 to rotate. The gear 56 rotating will drive another set of toothed plates 57 to rotate to the left. The toothed plate 57 moving will drive another set of connecting blocks 54 and insert blocks 53 to move to the left. At this time, the connecting block 54 will drive the insert block 53 to move outward at the same time. The insert block 53 moving outward will enter the slot 52, thereby limiting the mounting plate 51 and also limiting the protective cover 2. Then the curved beam can be placed on the bending machine body 1. Then the bending machine body 1 can be activated to bend the curved beam. Finally, the bent curved beam can be placed in the formwork. Finally, concrete can be poured into the formwork and allowed to cool naturally before use.

[0035] After a large number of curved beams have been bent, the electric push rod 55 can be activated to reset the toothed plate 57. Since the connecting block 54 and the insert block 53 are always subjected to the elastic force of the spring 510, when the toothed plate 57 and the connecting block 54 are separated, the insert block 53 will be separated from the slot 52. Finally, the protective cover 2 can be opened, and the iron filings on the top of the bending machine body 1 can be cleaned.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
