Description

Technical Field

[0001] This utility model relates to a composite device, specifically a hot bending and flattening composite device. Background Technology

[0002] A spring made of a single steel plate or multiple steel plates stacked together is called a leaf spring. Multiple leaf springs stacked together have a large buffering and vibration damping capacity and are often used in heavy trucks and large vehicles.

[0003] Leaf springs typically need to be machined into an arc shape to give them curvature. In existing technology, some leaf springs are subjected to hot bending impact treatment using an impact hammer after heating. The impact hammer applies impact force to the heated leaf spring. When the stress generated by this impact force exceeds the yield strength of the leaf spring, the leaf spring will undergo plastic deformation. After multiple impacts, the leaf spring can be machined into an arc shape.

[0004] When impacting leaf springs, the relative position of the leaf spring and the impact hammer has specific requirements. The operator needs to be highly skilled. The operation requires a high level of technical expertise and proficiency. Insufficient experience can easily cause the leaf spring to shift, resulting in deviations in the curvature of the leaf spring and affecting the stacking of individual leaf springs. This makes the operation quite difficult. Utility Model Content

[0005] The purpose of this utility model is to provide a hot bending and flattening composite equipment, which solves the problems of high technical requirements and difficult operation in the existing technology.

[0006] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a hot bending continuous flat composite device, including an impact table and a top plate that is located above the impact table and can be raised and lowered. An impact hammer is provided at the bottom of the top plate corresponding to the top of the impact table. Limiting seats are provided on both sides of the impact table and can move towards the impact table. The side of the limiting seat facing the impact table can abut against the side wall in the width direction of the steel leaf spring. The limiting seat is provided with a slot that runs vertically through it. A push plate that can move downward into the slot is provided at the bottom of the top plate. The lower side of the push plate is provided with an outward protrusion that can push the limiting seat towards the impact table, corresponding to the bottom of the impact hammer.

[0007] As a further preferred technical solution of this utility model; a rotating shaft is provided on the side of the slot facing the impact table, and a roller is sleeved on the rotating shaft. The upper side of the push plate is provided with an inner concave part that cooperates with the outer wall of the roller, and the outer convex part of the push plate can push the roller to move towards the impact table.

[0008] As a further preferred technical solution of this utility model, the impact table is also provided with fixed seats on both sides, and the fixed seats are provided with a horizontally arranged limiting cavity in the middle. The limiting seat is located in the limiting cavity and cooperates with the inner wall of the limiting cavity. The fixed seat is provided with a through groove arranged vertically and communicating with the slot.

[0009] As a further preferred technical solution of this utility model; the through groove includes an extension groove located below the slot, the push plate can be moved downward into the through groove, and when the outward protrusion is located in the extension groove, the inward concave part is located in the slot.

[0010] As a further preferred technical solution of this utility model, the limiting seat is provided with a fixing groove on the side facing the impact table, the fixing groove is provided with a limiting member that can abut against the side wall of the steel leaf spring and be bolted to the limiting seat, the bottom of the fixing groove is provided with a groove, and the bottom of the limiting member is provided with a protrusion that cooperates with the groove.

[0011] As a further preferred technical solution of this utility model, the front end of the impact table extends to the outside of the fixed base and the impact hammer is located at the bottom of the top plate above the front end.

[0012] Therefore, this utility model has the characteristics of automatically adjusting the position of the steel leaf spring relative to the impact hammer, ensuring the accuracy of the impact position, reducing the difficulty of operation and technical requirements, and continuing to flatten after the impact is completed, realizing the combination of hot bending treatment and flattening treatment, making the application of this equipment more comprehensive.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1 and 4As shown, a hot bending and flattening composite device includes an impact table 1 and a top plate 2 located above the impact table 1 and movable by lifting. The top plate 2 is connected to an external hydraulic press or cylinder and can be driven to move up and down, thereby driving the impact hammer 3 and the push plate 21 to move up and down synchronously. The bottom of the top plate 2 is provided with the impact hammer 3 above the impact table 1. The front end of the impact table 1 extends to the outside of the fixed seat 5 and the impact hammer 3 is located at the bottom of the top plate 2 above the front end. The impact table 1 is a long strip structure that cooperates with the leaf spring, extending from between the two fixed seats 5 to the front side. The impact hammer 3 is located above this side and connected to the top plate 2. Both sides of the impact table 1 are provided with mutually symmetrically arranged limiting seats 4 that can move toward the impact table 1. The side of the limiting seat 4 facing the impact table 1 can abut against the side wall in the width direction of the leaf spring. The two limiting seats 4 can move synchronously toward the leaf spring on the impact table 1 and abut against the side wall of the leaf spring to achieve the effect of pressing the leaf spring. The automatic position correction is achieved by a slot 41 that runs vertically through the limiting seat 4. The bottom of the top plate 2 has a push plate 21 that can move downward into the slot 41. The lower side of the push plate 21, corresponding to the lower part of the impact hammer 3, has an outward protrusion 211 that can push the limiting seat 4 toward the impact table 1. The push plate 21 can be driven down into the slot 41 by the top plate 2. When the push plate 21 is in the slot 41, the outward protrusion 211 on the lower side of the push plate 21 can push the limiting seat 4 toward the impact table 1 (i.e., the side wall of the steel leaf spring). This allows the two limiting seats 4 to simultaneously squeeze the steel leaf spring to correct its position. Thus, the relative position of the steel leaf spring and the impact hammer 3 can be quickly and accurately adjusted before impact, ensuring the accuracy of the impact position, reducing the difficulty of operation and technical requirements. After impact, flattening can be performed, achieving a combination of hot bending and flattening, making the application of this equipment more comprehensive.

[0019] like Figure 2As shown, a rotating shaft 42 is provided on the side of the slot 41 facing the impact table 1, arranged front and rear. The rotating shaft 42 is located on the front and rear sides of the slot 41 in the front-rear direction. A roller 421 is sleeved on the rotating shaft 42 and can roll on the rotating shaft 42. The upper side of the push plate 21 has an inner recess 212 that cooperates with the outer wall of the roller 421. The outer protrusion 211 of the push plate 21 can push the roller 421 to move towards the impact table 1. The upper side of the push plate 21 facing the impact table 1 has an inner recess 212 and an outer protrusion 211. When the top plate 2 is driven to move downward and the push plate 21 moves downward synchronously, the outer protrusion 211 of the push plate 21 is first located inside the slot 41 and pushes the roller 421. The roller 421 drives the limiting seat 4 to move synchronously toward the side of the leaf spring to position the leaf spring. Then the push plate 21 moves down. During the downward movement of the push plate 21, the roller 421 is driven to roll by the outer protrusion 211, which can avoid the friction between the outer protrusion 211 and the roller 421 when the push plate 21 moves, thereby reducing the wear between the outer protrusion 211 and the roller 421. The push plate 21 continues to move down until the inner concave part 212 is located in the slot 41. There is a gap between the inner concave part 211 and the roller 421, and the impact hammer 3 is in contact with the top surface of the leaf spring at this time. Thus, after the positioning of the leaf spring is completed, the pushing of the limiting seat 4 is canceled, and the impact hammer 3 then begins to impact the leaf spring.

[0020] like Figure 1 and 3 As shown, the impact table 1 is also provided with fixed seats 5 on both sides. The fixed seat 5 has a horizontally arranged limiting cavity 51 in the middle. The limiting seat 4 is located in the limiting cavity 51 and cooperates with the inner wall of the limiting cavity 51. The limiting seat 4 is located in the limiting cavity 51 of the fixed seat 5, so that the limiting seat 4 can move stably through the limiting cavity 51 for guidance and limitation. The fixed seat 5 is provided with a longitudinally arranged through groove 52 that communicates with the slot 41. The through groove 52 passes through the fixed seat 5 from top to bottom and passes through the slot 41. The through groove 52 includes the slot located in the slot. When the push plate 21 moves down, it enters the through groove 52 from the upper side and passes through the slot 41 into the extension groove 521 below the through groove 52. When the push plate 21 is completely inside the through groove 52, the protruding part 211 is inside the extension groove 521, while the concave part 212 is inside the slot 41. This ensures the accuracy of the push plate 21 in driving the movement of the limit seat 4 when it moves down, and ensures reliable positioning and accurate and efficient position adjustment of the leaf spring.

[0021] like Figure 1As shown, a fixing groove 43 is provided on the side of the limiting seat 4 facing the impact table 1. A limiting member 44 is provided in the fixing groove 43, which can abut against the side wall of the leaf spring and is bolted to the limiting seat 4. The limiting member 44 is fitted in the fixing groove 43. The top of the limiting member 44 bends and extends towards the top of the limiting seat 4 and is fixed to the top of the limiting member 44 by bolts. A groove 431 is provided at the bottom of the fixing groove 43. A protrusion 441 is provided at the bottom of the limiting member 44, which cooperates with the groove 431. The bottom of the limiting member 44 is locked in place by the protrusion 441 and the groove 431 of the fixing groove 43, thereby positioning the limiting member 44 and ensuring the connection stability of the limiting member 44. At the same time, it is convenient to replace different limiting members 44 according to leaf springs of different widths. The side of the limiting member 44 facing the leaf spring is a smooth surface to ensure the positioning accuracy when adjusting the position of the leaf spring by abutting against the side wall of the leaf spring.

[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
