Description

Technical Field

[0001] The invention relates to a hardware mold, in particular to a loading and unloading mechanism and a bending mold. Background Art

[0002] Bending dies are tools used by press brakes to shape sheet metal. These tools are composed of various parts, with different dies consisting of different components. They primarily shape the object by changing the physical state of the material being molded. They are used to shape products into specific shapes and sizes under the pressure of the press brake.

[0003] In existing technologies, the bending process typically requires manual workpiece placement on a bending die, followed by a bending punch to press the workpiece. This method is slow, unsafe, and expensive, consuming time and effort, impacting production efficiency and increasing costs, hindering business development. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a loading and unloading mechanism and a bending die that can improve the level of intelligence, simplify the bending process, solve the problem of poor bending consistency of products, and reduce production costs.

[0005] In order to solve the above technical problems, the present invention is implemented by adopting the following technical solutions:

[0006] In one aspect, the present invention provides a loading and unloading mechanism, comprising a conveyor track, wherein a product support and a non-return assembly are arranged in the conveyor track along the product conveying direction; a plurality of non-return assemblies are provided, and the spacing between adjacent non-return assemblies is not less than the width of the product; each non-return assembly is arranged on the same drive plate, and the drive plate is connected to the drive mechanism;

[0007] The check assembly includes a base and a check plate, and the check plate is retractably connected to the base; when the driving plate moves toward the lower material area, the check plate can push the front product adjacent to it to advance toward the lower material area; when the driving plate moves to the upper material area, the check plate can retract to the lower part of the rear product under the pressure of the rear product adjacent to it.

[0008] Furthermore, the non-return plate includes a connecting portion and a non-return portion, the connecting portion is hinged to one end of the base close to the loading area, and the non-return portion is elastically connected to one end of the base close to the unloading area.

[0009] Furthermore, a telescopic gap is left between the lower surface of the non-return plate and the upper surface of the base, and the non-return portion is elastically connected to the base via a spring provided in the telescopic gap.

[0010] Furthermore, the non-return portion is arranged obliquely relative to the connecting portion, and an angle formed by an upper surface of the non-return portion and an upper surface of the connecting portion is greater than 90 degrees.

[0011] Furthermore, the driving mechanism includes a cylinder, and a piston rod of the cylinder is transmission-connected to the driving plate.

[0012] Furthermore, a cylinder seat is provided at the bottom of the cylinder, and the cylinder seat is fixedly connected to the conveying track through a bottom plate.

[0013] On the other hand, the present invention also provides a bending mold, comprising a bending module group and the loading and unloading mechanism described in any one of the aforementioned items, wherein the bending module group is arranged at the unloading end of the loading and unloading mechanism, and the bending module group comprises a bending punch and a bending die base. When the bending punch and the bending die base are in an open mold state, the loading and unloading mechanism can convey the product to the bending die base.

[0014] Furthermore, the conveying track of the loading and unloading mechanism extends to the bending die base and is fixedly connected to the bending die base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a loading and unloading mechanism, which arranges a non-return component on a conveying track and uses a driving mechanism to drive the product to move on the conveying track. When the driving plate moves toward the lower material area, the non-return plate can push the front product adjacent to it to move forward to the lower material area; when the driving plate moves to the upper material area, the non-return plate can retract to the lower part of the rear product under the pressure of the rear product adjacent to it. The conveying track and the driving mechanism work together to improve the level of intelligence, reduce manual operation, and at the same time improve production safety and reduce production costs.

[0017] 2. The present invention provides a bending die comprising a bending die set and a loading and unloading mechanism. The bending die set includes a bending punch and a bending die holder. The bending die set is disposed at the unloading end of the loading and unloading mechanism. When the bending punch and the bending die holder are in the open state, the loading and unloading mechanism can convey the product onto the bending die holder, and the bending die set begins to operate and bend the product into shape. The use of the bending die set and loading and unloading mechanism can simplify the bending process, ensure the uniformity of the product's bending degree, and improve the bending efficiency of the bending die.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] Example 1:

[0026] See also Figure 1 、 Figure 2The present invention provides a loading and unloading mechanism, comprising a conveyor track 1. Within the conveyor track 1, a product holder 2 and a check assembly 3 are arranged along the product conveying direction. Three check assemblies 3 are provided. It should be noted that multiple check assemblies 3 may be provided, for example, five or ten check assemblies 3 may be provided, depending on the length of the conveyor track 1. Accordingly, the spacing between adjacent check assemblies 3 is no less than the width of the product. The loading and unloading mechanism is also provided with a drive plate 4, on which each check assembly 3 is mounted. Products are conveyed along the conveyor track 1 via a drive mechanism 5, which is connected to the drive plate 4. Those skilled in the art will appreciate that the drive mechanism 5 may be a cylinder or other drive mechanism. The drive mechanism 5 is provided with a piston rod 6, which is in transmission connection with the drive plate 4. To facilitate the operation of the drive mechanism 5, a cylinder base 7 is provided at the bottom of the cylinder. The cylinder base 7 is fixedly connected to the conveyor track 1 via a base plate 8 to stabilize the drive mechanism 5 and ensure that products can be conveyed along the conveyor track 1.

[0027] As a preferred embodiment, the check assembly 3 includes a base and a check plate. The check plate is retractably connected to the base. When the drive plate 4 moves toward the lower feeding area, the check plate can push the product in front of it toward the lower feeding area. When the drive plate 4 moves toward the upper feeding area, the check plate can retract to the lower part of the product behind it under the pressure of the product behind it. The check plate includes a connecting portion and a check portion. The connecting portion is hinged to one end of the base near the upper feeding area, and the check portion is elastically connected to one end of the base near the lower feeding area. A telescopic gap is left between the lower surface of the check plate and the upper surface of the base. The check portion is elastically connected to the base via a spring provided in the telescopic gap. The check portion is tilted relative to the connecting portion, and the angle formed by the upper surface of the check portion and the upper surface of the connecting portion is greater than 90 degrees, for example, it can be 120 degrees.

[0028] By arranging the non-return assembly 3 on the conveying track 1 and using the driving mechanism 5 to drive the product to move on the conveying track 1, when the driving plate 4 moves toward the lower material area, multiple products can be transported to the lower material area by the conveying track 1, that is, the non-return plate can push the front product adjacent to it to advance to the lower material area; when the product reaches the loading area, that is, after the driving plate 4 moves to the upper material area, the non-return plate can retract to the lower part of the rear product under the pressure of the rear product adjacent to it. The conveying track 1 and the driving mechanism 5 work together to improve the level of intelligence, reduce manual operation, and at the same time improve production safety and reduce production costs.

[0029] Example 2:

[0030] The present invention also provides a bending die, see Figure 3 , including a bending module 9 and the loading and unloading mechanism described in Example 1, the bending module 9 is arranged at the unloading end of the loading and unloading mechanism, in detail, the bending module 9 includes a bending punch 10 and a bending die base 11, the bending punch 10 is arranged above the bending die base 11, when the bending punch 10 and the bending die base 11 are in the mold opening state, the loading and unloading mechanism can move the driving plate 4 toward the unloading area through the driving mechanism 5, thereby conveying the product to the bending die base 11. In more detail, the conveying track 1 of the loading and unloading mechanism extends to the bending die base 11, and the conveying track 1 is fixedly connected to the bending die base 11. The loading and unloading mechanism can convey the product to the bending die base 11. After the product is transported to the bending module 9, the bending punch 10 cooperates with the bending die base 11 to bend the product. The use of bending modules and loading and unloading mechanisms can simplify the bending process, ensure the consistency of the bending degree of the product, and improve the bending efficiency of the bending mold.
