Description

Technical Field

[0001] This utility model relates to the field of material support device technology, and in particular to a material support device for parts and a mold table. Background Technology

[0002] In related technologies, the automated handling and placement of parts onto molds by robotic arms during automotive stamping production has become a standard operating procedure. However, due to the material properties of the parts and the forming process, springback is a common phenomenon after forming. This springback prevents the parts from fitting well against the mold surface. When the mold's moving mechanism starts working, the misfitting parts interfere with the mechanism. This interference not only deforms the parts, severely reducing product quality, but also causes frequent production interruptions, affecting production rhythm, significantly reducing production efficiency, increasing production costs, and severely restricting the stability and reliability of automated stamping production. Utility Model Content

The material support block and the base are fixedly connected. The base and the driving mechanism are drive-connected. The driving mechanism can drive the material support mechanism to reciprocate along the first direction so that the material support mechanism can selectively support parts.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] The following is for reference. Figure 1 This invention describes a material feeding device 100 for parts and a mold table according to an embodiment of the present invention.

[0027] According to an embodiment of the present invention, a component support device 100 includes a support mechanism 10 and a drive mechanism 20. The support mechanism 10 and the drive mechanism 20 are arranged along a first direction and are connected in a transmission manner. The support mechanism 10 includes a support block 11 and a base 12. Along the first direction, the base 12 is located between the support block 11 and the drive mechanism 20. The support block 11 and the base 12 are fixedly connected. The base 12 and the drive mechanism 20 are connected in a transmission manner. The drive mechanism 20 can drive the support mechanism 10 to reciprocate along the first direction so that the support mechanism 10 can selectively support the component.

[0028] Among them, when the material support mechanism 10 and the drive mechanism 20 are as follows Figure 1 When placed in the position shown, Figure 1 In the first direction, the material support mechanism 10 and the drive mechanism 20 are arranged along the first direction and are connected by transmission. In some embodiments of this utility model, the material support mechanism 10 and the drive mechanism 20 can be connected by cylinder transmission, or by gear transmission, or by screw transmission. However, this utility model is not limited to these. The material support mechanism 10 and the drive mechanism 20 can also be connected by transmission in other ways, as long as the material support mechanism 10 and the drive mechanism 20 are connected by transmission.

[0029] Along the first direction, the base 12 is located between the support block 11 and the drive mechanism 20. The support block 11 and the base 12 are fixedly connected. In some embodiments of this utility model, the support block 11 and the base 12 can be fixedly connected by adhesive or by bolts. However, this utility model is not limited to these methods, and the support block 11 and the base 12 can also be fixedly connected by other means, as long as the support block 11 and the base 12 are fixedly connected. The fixed connection of the support block 11 and the base 12 forms a rigid whole, reducing vibration or deformation during movement and ensuring the support accuracy of the support device 100.

[0030] The base 12 and the drive mechanism 20 are connected by a transmission connection, enabling the drive mechanism 20 to drive the material support mechanism 10 to reciprocate along a first direction. Furthermore, the base 12 can be directly connected to the connecting rod 22 of the drive mechanism 20, reducing intermediate transmission links (such as connecting rods and gears), lowering energy loss, and improving transmission efficiency. The base 12 can be made of high-strength, lightweight materials (such as aluminum alloy), reducing weight while ensuring structural strength, lowering the load on the drive mechanism 20, and improving motion response speed.

[0031] The base 12 is located between the support block 11 and the drive mechanism 20 and can serve as an intermediate support. It can disperse the reaction force when the support block 11 is subjected to force, prevent the drive mechanism 20 from directly bearing lateral force or impact load, and extend the service life of the drive mechanism 20.

[0032] In a specific embodiment of this utility model, the driving mechanism 20 can be a driving cylinder structure. The driving mechanism 20 can drive the material support mechanism 10 to reciprocate along the first direction, enabling the material support mechanism 10 to extend or retract along the first direction, so that the material support mechanism 10 can selectively support the parts. Specifically, when the parts are installed on the mold table, the driving mechanism 20 can drive the material support mechanism 10 to extend towards the parts along the first direction and abut against the parts to generate a pushing force and support effect on the parts, thereby enabling the parts to fit with the mold surface of the mold table, so as to avoid misalignment of the parts and interference with the moving mechanism. When the moving mechanism of the mold table starts to work, the driving mechanism 20 can drive the material support mechanism 10 away from the parts along the first direction, so as to remove the material support mechanism 10 before the moving mechanism interferes with the material support mechanism 10, thereby avoiding interruption of the production process, improving production efficiency, and also improving production stability and parts quality.

[0033] According to the embodiment of the present utility model, the material support device 100 for parts selectively supports the parts through the material support mechanism 10. This ensures that the parts are in contact with the mold surface before the movable mechanism of the mold table is working, so as to avoid the parts interfering with the movable mechanism due to non-contact with the mold surface, thereby avoiding deformation or damage to the parts. It can also remove the material support mechanism 10 in time when the movable mechanism of the mold table is working, so as to avoid interference between the material support mechanism 10 and the movable mechanism of the mold table, thereby improving production stability and part quality.

[0034] According to some embodiments of the present invention, the support block 11 can be constructed as an elastic structure.

[0035] The support block 11 can be constructed as an elastic structure, such as rubber, silicone, or polyurethane. In this invention, the support block 11 is made of polyurethane elastic material, allowing it to buffer impact forces through elastic deformation when in contact with components, preventing scratches, indentations, or breakage. For non-planar or irregularly shaped components (such as curved glass or irregular metal parts), the elastic support block 11 can tightly adhere to the surface through localized deformation, improving support stability. The elastic material has inherent damping, which can absorb the vibration energy during the movement of the drive mechanism 20, reducing resonance between the support block 11 and the components and improving support accuracy. At the moment the drive mechanism 20 starts or stops, the elastic support block 11 stores or releases energy through deformation, slowing down acceleration changes and making the force on the components more uniform, preventing slippage or tipping. This further enhances the protective, adaptable, and reliable support capabilities of the support device 100 for the components.

[0036] According to some embodiments of this utility model, such as Figure 1 As shown, along the first direction, the end face of the support block 11 facing away from the base 12 is the support surface 13, which is used to contact the parts.

[0037] The support surface 13 contacts the component along the first direction. The flatness or specific shape (such as V-shape or arc shape) of the support surface 13 applies a unidirectional constraint force to the component, avoiding positioning deviations caused by multi-directional degrees of freedom. The support surface 13 can be designed with a corresponding shape (such as a plane, V-groove, or arc surface) based on the contact surface shape of the component (such as a plane, cylinder, or sphere) to achieve geometric matching and improve positioning stability.

[0038] According to some embodiments of this utility model, such as Figure 1 As shown, the support surface 13 can be an arc-shaped surface.

[0039] The support surface 13 can be curved, allowing it to form surface contact with the component rather than point or line contact. This increases the contact area and fit, disperses unit pressure, and prevents indentations or deformation caused by localized stress concentration. The curved support surface 13 can simultaneously apply constraint forces to the component in both horizontal and vertical directions, suppressing slippage or rotation during the support process and improving positioning stability. Furthermore, the curved support surface 13 is applicable to components of most shapes, enhancing the versatility of the support device 100.

[0040] According to some embodiments of the present invention, the driving mechanism 20 includes a driving part 21 and a connecting rod 22, the driving part 21 and the connecting rod 22 are telescopically connected along a first direction, and the connecting rod 22 is fixedly connected to the material support mechanism 10.

[0041] The drive unit 21 can be a drive cylinder, and the connecting rod 22 is a cylinder piston rod. The drive unit 21 and the connecting rod 22 are telescopically connected along a first direction, and the connecting rod 22 is fixedly connected to the material support mechanism 10. The drive cylinder can provide stable and continuous power, converting energy into mechanical energy through compressed air to drive the piston rod in a linear motion. This power output method enables the material support mechanism 10 to obtain sufficient force when supporting parts, especially suitable for scenarios requiring greater support force, such as supporting heavy metal parts, large packaging boxes, etc., to ensure that the parts maintain a stable position during processing. By adjusting the air intake and exhaust volume of the drive cylinder, the movement speed and displacement of the cylinder piston rod can be precisely controlled to precisely control the speed and position of the material support mechanism 10, ensuring that the parts can accurately fit with the mold table surface, improving product quality and production efficiency.

[0042] According to some embodiments of the present invention, the material support device 100 may further include: an anti-rotation structure, which cooperates with the connecting rod 22 to restrict the connecting rod 22 from rotating about a first direction.

[0043] The anti-rotation structure effectively prevents the connecting rod 22 from rotating around the first direction, ensuring that it moves strictly along a predetermined linear trajectory. This, in turn, ensures that the material-supporting mechanism 10 stably supports the components, guaranteeing that the components accurately fit against the mold table surface, avoiding production interruptions, and improving product quality and production efficiency. For example, a keyway can be machined on the peripheral wall of the connecting rod 22, and a guide key can be formed on the inner peripheral wall of the drive unit 21. Both the guide key and the keyway extend along the first direction, and the guide key and the keyway are fitted together. The contact between the guide key and the inner wall of the keyway restricts the rotation of the connecting rod 22 around the first direction. Alternatively, a spline can be machined on the outer peripheral wall of the connecting rod 22, and a spline sleeve can be installed on the drive unit 21. The fitting and assembly of the spline and the spline sleeve restricts the rotation of the connecting rod 22 around the first direction. However, this utility model is not limited to these methods. The anti-rotation structure can be reasonably selected and set according to the actual structure of the connecting rod 22. No specific limitation is made here, as long as the anti-rotation structure can restrict the rotation of the connecting rod 22 around the first direction.

[0044] According to some embodiments of the present invention, the material support device 100 may further include: a controller, which is communicatively connected to the drive mechanism 20, and the controller is configured to control the operation of the drive mechanism 20.

[0045] The controller can be configured as a control panel. According to the angle corresponding to the falling position of the press slide, the air supply angle can be input on the control panel of the press to precisely control the extension and retraction of the drive cylinder of the drive mechanism 20 and the time of material support.

[0046] Specifically, such as Figure 1As shown, the drive mechanism 20 may include a first vent pipe 23 and a second vent pipe 24. Both the first vent pipe 23 and the second vent pipe 24 can be used for air intake and exhaust. For example, when the connecting rod 22 needs to extend, the control panel can control the first vent pipe 23 to intake and the second vent pipe 24 to exhaust. When the connecting rod 22 needs to retract, the control panel can control the second vent pipe 24 to intake and the first vent pipe 23 to exhaust. Furthermore, by triggering the air supply when the press slider falls to a specific angle (e.g., 15° from the bottom dead center) on the control panel, the timing of the extension and retraction of the connecting rod 22 can be precisely controlled. For example, when the press slider falls to the preset angle, the control panel outputs a signal to open the solenoid valve, compressed air enters the drive cylinder, pushing the connecting rod 22 to extend, thereby driving the material support mechanism 10 to complete the part support action. When the press slider approaches the bottom dead center or returns after completing the stamping process, the control panel cuts off the air supply, the connecting rod 22 retracts, and the material support mechanism 10 releases the part, avoiding interference between the moving mechanism and the material support mechanism 10, thus facilitating subsequent operations. Since the angle of the press slide has a fixed functional relationship with time (such as linear correlation between the angle and time when rotating at a constant speed), the precise synchronization between the supporting action of the material support mechanism 10 and the movement of the press slide can be indirectly achieved by controlling the angle of the press slide. This enables precise support of the parts and avoids interference between the moving mechanism of the mold table and the material support mechanism 10, facilitating subsequent process operations, avoiding production interruptions, and improving product quality and production efficiency.

[0047] According to some embodiments of the present invention, the material support device 100 may further include: a mounting base 30, and a drive mechanism 20 fixed to the mounting base 30.

[0048] In this invention, the drive mechanism 20 is fixed to the mounting base 30. In some embodiments, the mounting base 30 and the drive mechanism 20 can be fixedly connected by welding or by bolts. However, this invention is not limited to these methods, and the drive mechanism 20 and the mounting base 30 can also be fixedly connected by other means, as long as the drive mechanism 20 is fixed to the mounting base 30. The mounting base 30 can be fixed on the mold platform, and the drive mechanism 20 is fixed to the mold platform through the mounting base 30, providing a stable mounting platform for the drive mechanism 20 to ensure its stability, thereby ensuring the stability and reliability of the material support device 100.

[0049] The mold platform according to an embodiment of the present utility model includes:

[0050] A mold stand is used to hold parts.

[0051] The material support device 100 is the aforementioned material support device 100 for parts. The material support device 100 is installed on the mold table and is used to support the parts on the mold table.

[0052] In the automated stamping production process, parts are automatically picked up and placed onto the mold table by a robotic arm. Due to the springback characteristics of the parts, the parts cannot fit well with the mold surface of the mold table, which poses a risk of interference between the parts and the moving mechanism of the mold table. The material support device 100 is installed on the mold table and is used to support the parts on the mold table, so that the parts fit well with the mold surface of the mold table, thereby avoiding misalignment of the parts and interference with the moving mechanism. When the moving mechanism of the mold table starts to work, the drive mechanism 20 can drive the material support device 10 away from the parts in the first direction, so that the material support device 10 can be moved away before the moving mechanism interferes with the material support device 10. This can avoid interruption of the production process, improve production efficiency, and also improve production stability and part quality.
