Technical Field

[0001] This utility model relates to the field of mold accessories technology, and in particular to a positioning and support device for stamping molds. Background Technology

[0002] In the stamping process of automotive body sheet metal parts, positioning fixtures are needed to ensure the consistency of the sheet metal's position during each feeding. Good consistency in the product is only possible under the same stamping parameters. The accuracy and stability of the sheet metal's positioning directly affect the final dimensional accuracy of the parts, the accuracy of the sheet metal boundaries, and the stability of the sheet metal's gravitational state during the forming process. Both of these factors are essential to guarantee good product formability.

[0003] For example, CN109759510A, published on May 17, 2019, discloses an automotive sheet metal stamping die; it includes a base plate, a base, a lower die holder, an upper die, a top plate, a first cylinder, a support unit, an ejector unit, a pusher unit, and a controller; the die is fixedly connected to the top plate via the first cylinder, and the upper die has racks at both ends; the base is fixedly installed on the base plate; the lower die holder is fixedly connected to the bottom of the base via the support unit, and the lower die holder has T-shaped holes; the ejector units are located in the T-shaped holes, and the ejector units include ejector pins and U-shaped brackets; the pusher unit includes a first gear, a rocker arm, a first rod, a T-shaped rod, and a wedge block. In the above-disclosed die, the sheet metal falls directly onto the die during use, and the surface of the sheet metal is easily damaged, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical positioning and support device for stamping dies. This invention uses a buffer assembly on the base to cushion the positioning support plate, thus ensuring that the sheet metal is protected when it falls onto the positioning support plate, preventing surface damage from rigid impacts and thus improving its practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a stamping die positioning support device, including a base, a fixed frame on the base, a positioning support plate on the fixed frame, and a buffer assembly on the base to buffer the positioning support plate.

[0006] One end of the positioning support plate is hinged to the fixed frame, and the other end of the positioning support plate is connected to the base through an elastic component. The fixed frame is provided with a limiting block.

[0007] The buffer assembly includes a spring and connecting plates. The two connecting plates are respectively connected to the positioning support plate and the base, and the two ends of the spring are respectively connected to the two connecting plates.

[0008] The two connecting plates are respectively connected to the base and the positioning support plate by the first bolt.

[0009] The connecting plate is provided with a first through hole for the first bolt to pass through, and the base and positioning support plate are provided with a groove to accommodate the first bolt, and the groove is provided with a threaded hole that mates with the first bolt.

[0010] The fixing frame has a slot, the positioning support plate extends into the slot, and the positioning support plate is connected to the fixing frame by a pin.

[0011] The fixing frame is provided with mounting holes for connecting to the pin shaft, and the positioning support plate is provided with a second through hole for the pin shaft to pass through.

[0012] Both the first and second through holes are oblong holes, and the bottom of the base is provided with an adjustment shim.

[0013] The positioning support plate is provided with a contact groove that contacts the sheet material.

[0014] The base is provided with a third through hole, and a second bolt is provided in the third through hole.

[0015] The beneficial effects of this utility model are:

[0016] The base is installed on the stamping die. When the sheet metal moves and comes into contact with the positioning support plate on the fixed frame, the buffer assembly between the positioning support plate and the base provides buffer support for the sheet metal. The buffer assembly protects the sheet metal, thus preventing damage when the sheet metal is loaded onto the die, making it more practical.

[0017] The buffer assembly consisting of a spring and a connecting plate provides cushioning for the positioning support plate. The first bolt allows for convenient position adjustment of the connecting plate on the base and the positioning support plate. The first through hole on the connecting plate and the second through hole on the positioning support plate facilitate lateral adjustment of the positioning support plate's position. By setting different numbers of adjusting shims at the lower end of the base, the entire device can accept plates of different sizes, making it more practical. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figure 1-2 As shown, the stamping die positioning support device includes a base 1, a fixed frame 2 on the base 1, a positioning support plate 3 on the fixed frame 2, and a buffer assembly on the base 1 to buffer the positioning support plate 3. Specifically, the fixed frame 2 is welded to the base 1.

[0024] When in use, the base 1 is installed on the stamping die. When the sheet metal moves and comes into contact with the positioning support plate 3 on the fixed frame 2, the buffer assembly between the positioning support plate 3 and the base 1 provides buffer support for the sheet metal. The buffer assembly protects the sheet metal, thus preventing damage when the sheet metal is loaded onto the die, making it more practical.

[0025] Specifically, one end of the positioning support plate 3 is hinged to the fixed frame 2, and the other end of the positioning support plate 3 is connected to the base 1 through an elastic component. The fixed frame 2 is provided with a limiting block 4. When the plate falls and contacts the positioning support plate 3, one end of the positioning support plate 3 rotates on the fixed frame 2, and the other end of the positioning support plate 3 is supported by a buffer component, thereby ensuring that the positioning support plate 3 stably receives the plate. In addition, the limiting block 4 is set to prevent the positioning support plate 3 from rotating too much due to impact. Specifically, the limiting block 4 is connected to the fixed frame 2 by two bolts and is set on the upper side of the positioning support plate 3.

[0026] The buffer assembly includes a spring 5 and a connecting plate 6. The two connecting plates 6 are respectively connected to the positioning support plate 3 and the base 1. The two ends of the spring 5 are respectively connected to the two connecting plates 6. The connection between the positioning support plate 3 and the base 1 is achieved through the spring 5 and the connecting plate 6. The buffering work of the positioning support plate 3 is achieved through the elastic force of the spring 5.

[0027] The two connecting plates 6 are respectively connected to the base 1 and the positioning support plate 3 by the first bolt 7, and the connecting plates 6 can be easily disassembled and assembled by the first bolt 7.

[0028] Specifically, the connecting plate 6 is provided with a first through hole 8 for the first bolt 7 to pass through, and the base 1 and the positioning support plate 3 are provided with a recess 9 to accommodate the first bolt 7. The recess 9 is provided with a threaded hole that mates with the first bolt 7. The first bolt 7 passes through the first through hole 8 on the connecting plate 6 and mates with the threaded hole on the base 1 or the positioning support plate 3, thereby realizing the installation of the connecting plate 6. The recess 9 is used to store the screw head of the first bolt 7, thereby hindering the movement of the positioning support plate 3.

[0029] The fixed frame 2 is provided with a slot 10, and the positioning support plate 3 extends into the slot 10. The positioning support plate 3 is connected to the fixed frame 2 through a pin 11. The pin 11 enables the positioning support plate 3 to rotate on the pipe frame 2, and the slot 10 enables the stable rotation of the positioning support plate 3, thereby ensuring the stable rotation of the positioning support plate 3.

[0030] The fixed frame 2 is provided with a mounting hole 12 for connecting to the pin 11, and the positioning support plate 3 is provided with a second through hole 13 for the pin 11 to pass through. The pin 11 passes through the mounting hole 12 and the second through hole 13 to realize the hinge operation of the positioning support plate 3.

[0031] Both the first through hole 8 and the second through hole 13 are oblong holes. The oblong shape of the first through hole 8 facilitates the adjustment of the position of the connecting plate 6 on the base 1 and the positioning support plate 3, thereby facilitating the adjustment of the lateral position of the positioning support plate 3 on the base 1. The oblong shape of the second through hole 13 ensures that the positioning support plate 3 is always hinged to the fixed frame 2 when it moves laterally. The bottom of the base 1 is provided with an adjusting shim 15. By increasing the number of adjusting shims 15, the height of the positioning support 3 on the base 1 and the fixed frame 2 can be adjusted, thereby enabling the entire device to receive plates of different sizes. Specifically, the adjusting shim 15 is an annular shim.

[0032] The positioning support plate 3 is provided with a contact groove 14 that contacts the sheet metal. The contact groove 14 engages with the end of the sheet metal, thereby enabling the positioning support plate 3 to accurately receive the sheet metal, thus allowing the sheet metal to accurately fall onto the mold for stamping, which is more practical.

[0033] The base 1 is provided with a third through hole 17, and a second bolt 16 is provided in the third through hole 17. The base 1 is installed on the mold by means of the second bolt 16. In this embodiment, there are two second bolts 16.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
