Description

Technical Field

[0001] This utility model specifically relates to the field of automotive parts folding technology, and more specifically to an automotive central tunnel folding fixture. Background Technology

[0002] The central tunnel of a car is a longitudinal structural component located in the middle of the vehicle's cabin, running under the front and rear seats. The core function of the central tunnel is to house key components such as the drive shaft and exhaust pipe.

[0003] However, in practice, it has been noted that most current folding equipment folds the edges of workpieces by pressing between upper and lower dies. Since the folded workpiece is tightly attached to the die surface, it is easy for the workpiece to get stuck on the die during unloading. Forcibly demolding it can damage the workpiece. Furthermore, the edges of the workpiece need to withstand the extrusion force during folding, which can easily spread to other parts of the workpiece, causing deformation in other areas, which will affect the processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a folding fixture for automotive center consoles. Through the cooperation of a forming base mold and a forming mold seat, the upper surface of the workpiece to be processed is clamped and positioned to prevent deformation during folding. Furthermore, the internal expander on the folding support frame cooperates with the edge extruder to perform the folding process. Simultaneously, a hydraulic cylinder can drive the expander plate to retract inwards, facilitating rapid demolding of the processed workpiece and ensuring processing quality. This invention aims to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A car center console folding fixture includes a bottom mounting bracket, on which a folding support bracket is movably connected. Both sides of the folding support bracket are provided with internal expanders in a rectangular array. The bottom mounting frame includes a support plate, on which a mold bracket is fixedly connected, and at the end of the mold bracket is a forming bottom mold. Above the bottom molding mold is a top molding mold, which includes a molding mold base corresponding to the bottom molding mold, and the top of the molding mold base is fixedly connected to a pressure-bearing frame in a rectangular array.

[0006] As a further technical solution of this utility model, the folding support frame includes a support plate, in which mounting holes corresponding to the mold support are opened, and the forming bottom mold is located above the support plate; Both ends of the support plate are equipped with lifting cylinders, and the output rods of the lifting cylinders are fixedly connected to the support plate. Each lifting cylinder is also fixedly connected to an L-shaped bracket on the side away from the support plate, and is fixedly connected to the support cross plate through the L-shaped bracket.

[0007] As a further technical solution of this utility model, the bearing plate is also fixedly connected in a rectangular array with limiting sleeves, and the support plate is fixedly connected in a rectangular array with limiting columns corresponding to the limiting sleeves, and the ends of the limiting columns are slidably engaged with the limiting sleeves.

[0008] As a further technical solution of this utility model, the internal expander includes two sets of expander plates arranged in a rectangular array. Each set of expander plates is symmetrically arranged on both sides of the forming bottom mold. Each expander plate has a movable connecting seat integrally provided on the side away from the forming bottom mold. A hydraulic cylinder is also fixedly connected to the side of the movable connecting seat, and the hydraulic cylinder is fixedly connected to the bearing plate.

[0009] As a further technical solution of this utility model, the end of the hydraulic cylinder away from the movable connecting seat is also fixedly connected to a liquid delivery pipe, and the other end of the liquid delivery pipe is equipped with a switch valve.

[0010] As a further technical solution of this utility model, the top forming mold is provided with edge extruders on both sides symmetrically, and a top mounting frame is provided above the top forming mold. A pressure-bearing frame is also integrally provided above the forming mold base, and the pressure-bearing frame is fixedly connected to the bottom of the top mounting frame.

[0011] As a further technical solution of this utility model, the edge extruder includes an edge extrusion plate corresponding to the outer expansion plate, and an extrusion cylinder is fixedly connected to the side of the edge extrusion plate away from the forming mold base. Furthermore, a mounting bracket is fixedly connected to the side of the extrusion cylinder, and the top of the mounting bracket is fixedly connected to the top mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention places the workpiece to be processed between the forming bottom mold and the forming mold base. The workpiece is positioned by the extrusion between the forming bottom mold and the forming mold base, thereby improving the accuracy of bending the edge of the workpiece. At the same time, it can also prevent the stress at the bending point during the edge bending process from causing deformation at the top of the workpiece, thus improving the edge bending accuracy of the workpiece. In this invention, the output rod of the hydraulic cylinder drives the outer expansion plate to move outward through the movable connecting seat, applying an outward force to the inner side of the workpiece to be processed. At this time, the extrusion cylinder pushes the edge extrusion plate corresponding to the outer expansion plate to move inward, applying an inward force to the edge of the workpiece to be processed, thereby quickly bending the edge of the workpiece to be processed. When removing the processed workpiece, the hydraulic cylinder pushes the outer expansion plate to move inward, separating the contact position between the outer expansion plate and the workpiece to be processed, making it easier to remove the processed workpiece. In this invention, the lifting cylinder drives the entire bearing plate to move downwards, while the hydraulic cylinders arranged in a rectangular array on both sides of the bearing plate also drive the outer expansion plate downwards, thereby separating the outer expansion plate from the inside of the workpiece to be processed, making it easier for workers to quickly remove the processed workpiece.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-9 This utility model provides a car center channel folding fixture, including a bottom mounting frame 2, on which a folding support frame 3 is movably connected, and both sides of the folding support frame 3 are provided with internal expanders 4 in a rectangular array. The bottom mounting frame 2 includes a support plate 21, a mold support 23 is fixedly connected to the support plate 21, and a forming bottom mold 24 is fixedly connected to the end of the mold support 23. Above the molding bottom mold 24, there is also a top molding mold 8. The top molding mold 8 includes a molding mold base 81 corresponding to the molding bottom mold 24, and the top of the molding mold base 81 is fixedly connected to a pressure frame 82 in a rectangular array.

[0025] By adopting the above technical solution, the workpiece is placed between the forming bottom mold 24 and the forming mold base 81. Through the extrusion between the forming bottom mold 24 and the forming mold base 81, the workpiece can be positioned, thereby improving the accuracy of bending the edge of the workpiece. It can also prevent the bending point from being affected by stress during the bending process of the workpiece, which would cause deformation at the top of the workpiece, thereby improving the bending accuracy of the workpiece.

[0026] Furthermore, the folding support frame 3 includes a support plate 31, in which mounting holes 35 corresponding to the mold support 23 are provided, and the forming bottom mold 24 is located above the support plate 31. Both ends of the bearing plate 31 are provided with lifting cylinders 32, and the output rod of the lifting cylinder 32 is fixedly connected to the bearing plate 31. Each lifting cylinder 32 is also fixedly connected to an L-shaped bracket 33 on the side away from the bearing plate 31, and is fixedly connected to the support plate 21 through the L-shaped bracket 33.

[0027] More specifically, the bearing plate 31 is also fixedly connected in a rectangular array with limiting sleeves 34, and the supporting horizontal plate 21 is fixedly connected in a rectangular array with limiting columns 25 corresponding to the limiting sleeves 34, and the ends of the limiting columns 25 are slidably engaged with the limiting sleeves 34.

[0028] By adopting the above technical solution, the lifting cylinder 32 drives the bearing plate 31 to move downward as a whole, while the hydraulic cylinders 41 arranged in a rectangular array on both sides of the bearing plate 31 also drive the outer expansion plate 43 to move downward, thereby separating the outer expansion plate 43 from the inside of the workpiece 5 to be processed, further facilitating the worker to quickly remove the processed workpiece.

[0029] Furthermore, the internal expander 4 includes two sets of expander plates 43 arranged in a rectangular array. Each set of expander plates 43 is symmetrically arranged on both sides of the forming bottom mold 24. Each expander plate 43 has a movable connecting seat 42 integrally provided on the side away from the forming bottom mold 24. A hydraulic cylinder 41 is also fixedly connected to the side of the movable connecting seat 42, and the hydraulic cylinder 41 is fixedly connected to the bearing plate 31.

[0030] Furthermore, the hydraulic cylinder 41 is also fixedly connected to a liquid delivery pipe 44 at the end away from the movable connecting seat 42, and a switch valve 45 is installed at the other end of the liquid delivery pipe 44.

[0031] Furthermore, the top forming mold 8 is symmetrically provided with edge extruders 7 on both sides, and a top mounting bracket 1 is also provided above the top forming mold 8. A pressure-bearing bracket 82 is also integrally provided above the forming mold base 81, and the pressure-bearing bracket 82 is fixedly connected to the bottom of the top mounting bracket 1.

[0032] More specifically, the edge extruder 7 includes an edge extrusion plate 73 corresponding to the outer expansion plate 43, and an extrusion cylinder 72 is fixedly connected to the side of the edge extrusion plate 73 away from the forming mold base 81. Furthermore, a mounting bracket 71 is fixedly connected to the side of the extrusion cylinder 72, and the top end of the mounting bracket 71 is fixedly connected to the top mounting bracket 1.

[0033] By adopting the above technical solution, the output rod of the hydraulic cylinder 41 drives the outer expansion plate 43 to move outward through the movable connecting seat 42, applying an outward force to the inner side of the workpiece 5 to be processed. At this time, the extrusion cylinder 72 pushes the edge extrusion plate 73 corresponding to the outer expansion plate 43 to move inward, applying an inward force to the edge of the workpiece 5 to be processed, thereby quickly bending the edge of the workpiece 5 to be processed. When taking out the processed workpiece, the hydraulic cylinder 41 pushes the outer expansion plate 43 to move inward, so that the contact position between the outer expansion plate 43 and the workpiece 5 to be processed is separated, which facilitates the taking out of the processed workpiece.

[0034] Furthermore, the support plate 21 is fixedly connected to the bottom column 22 in a rectangular array above it, and the bottom of the top mounting bracket 1 is also fixedly connected to the top column 6 corresponding to the bottom column 22 in a ring array at the bottom, and the end of the top column 6 is inserted into the bottom column 22.

[0035] Furthermore, the switch valve 45 is located at the bottom of the support plate 31, and the liquid delivery pipe 44 passes around the side of the support plate 31.

[0036] The workpiece 5 to be processed is placed on top of the forming bottom mold 24, and the upper surface of the workpiece 5 to be processed is in contact with the forming mold base 81. Through the clamping between the forming bottom mold 24 and the forming mold base 81, the workpiece 5 to be processed can be positioned, and the surface of the workpiece 5 to be processed can be prevented from deforming under stress, thereby improving the folding quality.

[0037] The working principle of this utility model is as follows: First, the workpiece 5 to be processed is placed above the forming base mold 24. Then, the top mounting bracket 1 moves downwards until the forming mold base 81 at the bottom of the top mounting bracket 1 is in contact with the workpiece 5. Next, the lifting cylinder 32 pushes the support plate 31 upwards, simultaneously moving the internal expander 4 fixed on the support plate 31 upwards, causing the top of the expander plate 43 to penetrate into the inner side of the workpiece 5. Then, the output rod of the hydraulic cylinder 41 drives the expander plate 43 outwards through the movable connecting seat 42. Simultaneously, the extrusion cylinder 72 pushes the edge corresponding to the expander plate 43. The extrusion plate 73 moves inward, and the edge of the workpiece 5 is folded by the extrusion between the outer expansion plate 43 and the edge extrusion plate 73. After the folding is completed, the hydraulic cylinder 41 pushes the outer expansion plate 43 inward, so that the contact position between the outer expansion plate 43 and the workpiece 5 is separated. At the same time, the lifting cylinder 32 drives the bearing plate 31 to move downward as a whole, which facilitates the quick removal of the processed workpiece. The removal of the workpiece will not damage the workpiece, and prevents the workpiece from being tightly attached to the mold, which would make it impossible to remove the workpiece or cause the workpiece to deform due to excessive force during removal. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
