Description

Technical Field

[0001] This utility model relates to the field of bending machine slider technology, specifically to an electric servo bending machine slider joint connection assembly. Background Technology

[0002] Electric servo bending machines are highly versatile and suitable for a variety of applications, including precision sheet metal bending, small household appliances, and computer and equipment housings. They are specifically designed for bending metal materials and are ideal for precision sheet metal parts and machined components.

[0003] When bending a workpiece, the upper die descends and presses the workpiece below to bend and shape the tool. The lifting and lowering movement of the upper die is accomplished by the slider joint, servo motor and lead screw. After the upper die contacts the workpiece, it is subjected to the reaction force of the workpiece. At this time, the slider joint undergoes slight deformation. This leads to problems such as stiffness and abnormal noise in the slider joint during subsequent bending operations, and also reduces the service life of the bending machine.

[0004] Therefore, there is an urgent need to design an electric servo bending machine slider joint connection assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric servo bending machine slider joint connection assembly to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric servo bending machine slider joint connection assembly includes a bending machine wall plate, a lower template fixedly installed on the lower front side of the bending machine wall plate, two symmetrically distributed lifting screws independently arranged on the front side of the bending machine wall plate, and an upper template arranged below the lifting screws, and also includes a slider joint arranged between the bending machine wall plate and the upper template.

[0008] The slider joint includes a guide rail fixed to the outer walls of both sides of the bending machine wall panel. A sliding sleeve is slidably sleeved on the outer side of the guide rail. A mounting seat fixed to the side wall of the upper template is provided on one side of the outer wall of the sliding sleeve.

The mounting frame has symmetrically distributed guide wheels on both sides, and the two guide wheels are rolled on both sides of the second guide rail.

[0011] Preferably, the bending machine wall panel is provided with an installation groove, and a sealing plate is provided at the top of the installation groove, and the insert is slidably fitted inside the installation groove.

[0012] Preferably, the guide rail, the sliding sleeve, and the mounting base form a set of guide structures. The two sets of guide structures are symmetrically distributed about the bending machine wall panel. The insert, the limiting plate, the threaded column, the locking nut, and the clamping plate form a reinforcing structure.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5 As shown in the figure, an electric servo bending machine slider joint connection assembly provided by this utility model includes a bending machine wall plate 1, a lower template 2 fixedly installed on the lower front side of the bending machine wall plate 1, two symmetrically distributed lifting screws 4 independently arranged on the front side of the bending machine wall plate 1, and an upper template 3 arranged below the lifting screws 4. It also includes a slider joint 5 arranged between the bending machine wall plate 1 and the upper template 3. The slider joint 5 includes a guide rail 51 fixed on the outer walls of both sides of the bending machine wall plate 1, a sliding sleeve 52 slidably sleeved on the outside of the guide rail 51, a mounting seat 53 fixed on the side wall of the upper template 3 on one side of the outer wall of the sliding sleeve 52, a clamping plate 58 on one side of each of the two mounting seats 53, an insert 54 arranged between the two clamping plates 58, a threaded post 56 fixedly arranged on the outer walls of both sides of the insert 54, a limit plate 55 arranged on the outer walls of both sides of the insert 54, and a locking nut 57 threadedly connected to the outside of the threaded post 56.

[0030] In this embodiment, a bending machine wall panel 1 is included. The bending machine wall panel 1 consists of two symmetrically distributed panels. A lower template 2 is fixedly installed on the lower front side of the bending machine wall panel 1. The lower template 2 is used to support the workpiece. Two symmetrically distributed lifting screws 4 are independently arranged on the front side of the bending machine wall panel 1, and an upper template 3 is arranged below the lifting screws 4. The lifting screws 4 are rotated by a servo motor to realize the lifting and lowering movement of the upper template 3. The embodiment also includes a slider joint 5 arranged between the bending machine wall panel 1 and the upper template 3. The slider joint 5 guides the upper template 3 on the bending machine wall panel 1, ensuring the motion accuracy of the upper template 3 in bending the workpiece.

[0031] In this embodiment, the slider joint 5 includes a guide rail 51 fixed on the outer walls of both sides of the bending machine wall panel 1, and a sliding sleeve 52 is slidably sleeved on the outside of the guide rail 51.

[0032] Specifically, guide rail 51 is a cylindrical structure, and sliding sleeve 52 is an annular structure with an opening on one side. Sliding sleeve 52 covers the outside of guide rail 51. When the upper template 3 is raised or lowered, sliding sleeve 52 slides on guide rail 51.

[0033] Specifically, an mounting seat 53 fixed to the side wall of the upper template 3 is provided on one side of the outer wall of the sliding sleeve 52. A clamping plate 58 is provided on one side of each of the two mounting seats 53. Threaded posts 56 are fixed on both sides of the outer wall of the insert 54. Limiting plates 55 are provided on both sides of the outer wall of the insert 54. Locking nuts 57 are externally threaded to the threaded posts 56. There are two parallel locking nuts 57. By fixing the locking nuts 57 on the threaded posts 56, the clamping plate 58 is used to clamp the mounting seat 53, thereby preventing the sliding sleeves 52 on both sides of the bending machine wall plate 1 from expanding outward. This makes the contact between the sliding sleeve 52 and the guide rail 51 more compact, improves the accuracy of the movement, and makes the vertical movement of the slider joint 5 and the lifting movement of the lifting screw 4 as close as possible to the same axis.

[0034] Specifically, an insert 54 is provided between the two clamping plates 58, an installation groove is provided on the bending machine wall plate 1, and a sealing plate is provided on the top of the installation groove. The sealing plate connects to the top of the installation groove, ensuring the integrity of the bending machine wall plate 1. The insert 54 slides inside the installation groove.

[0035] Specifically, guide rail 51, sliding sleeve 52 and mounting base 53 form a set of guide structures. The two sets of guide structures are symmetrically distributed about the bending machine wall panel 1. Insert block 54, limit plate 55, threaded column 56, locking nut 57 and clamping plate 58 form a reinforcement structure. The reinforcement structure realizes the pulling between the two sets of guide structures. The reinforcement structure is used to realize the support and reinforcement of the guide structure, which greatly improves the movement accuracy of the upper template 3.

[0036] Specifically, the reinforcing structure and the guiding structure rise and fall synchronously with the upper template 3. The upper template 3 drives the guiding structure to rise and fall, while the reinforcing structure is fastened to the guiding structure. Therefore, the two slide inside the installation groove.

[0037] In this embodiment, an auxiliary wheel set 6 is provided on the outer wall of the bending machine wall panel 1 near the upper template 3. The auxiliary wheel set 6 is used at least for guiding the upper template 3 when it moves up and down.

[0038] Specifically, the auxiliary wheel assembly 6 includes a second guide rail 61 installed on one side of the outer wall of the upper template 3 and a mounting bracket 62 fixed on the side wall of the bending machine wall panel 1. The mounting bracket 62 has symmetrically distributed guide wheels 63 on both sides. The two guide wheels 63 are rolled on both sides of the second guide rail 61. When the upper template 3 is raised and lowered, the second guide rail 61 is raised and lowered inside the two guide wheels 63, and the guide wheels 63 roll, which further improves the accuracy of the movement of the upper template 3.

[0039] like Figures 6 to 7 As shown, the guide rail 61 in the auxiliary wheel set 6 adopts the following structural form:

[0040] The guide rail 61 is provided with two T-shaped countersunk holes distributed vertically. A connecting screw 611 and an adjusting sleeve 612 fitted on the outside of the connecting screw 611 are installed in the countersunk holes.

[0041] The side of guide rail 2 61 is provided with an internal threaded hole that communicates with the T-shaped countersunk hole, and a set screw 613 is installed in the internal threaded hole;

[0042] An inwardly sloping adjustment surface is provided at the base of the adjusting sleeve 612 corresponding to the position of the set screw 613.

[0043] Due to manufacturing and assembly errors during the assembly process, the cumulative effect of these errors causes guide rail 2 61 to be not in its theoretically vertical position. Therefore, vertical adjustment of guide rail 2 61 is necessary. This is achieved by using the set screw 613 to push the adjusting sleeve 612, adjusting guide rail 2 61 towards the upper template 3. This adjustment range is very small (approximately 1-5 microns), and is one of the main causes of stiff movement and abnormal noise. Adjusting the adjusting sleeve 612 with the set screw 613 ensures guide rail 2 61 is in its theoretically vertical position, thus eliminating the source of the abnormal noise. It is important to note that the remaining sliding surfaces can accommodate this small adjustment range. This adjustment eliminates abnormal noise from the sliding surfaces. Since there is a process clearance between the T-shaped countersunk hole and the connecting screw 611, this clearance fully accommodates this adjustment operation.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
