Description

Technical Field

[0001] This utility model belongs to the field of manufacturing, and specifically relates to a novel bonding, bending and assembly fixture. Background Technology

[0002] In the die-cutting and hardware assembly fields, traditional assembly, bonding, and bending processes face many problems. One person cannot perform multiple assembly, bonding, and bending processes; assembly requires the assistance of two or more workers. This labor-intensive approach is not only inefficient but also highly dependent on manual labor, leading to increased production costs.

[0003] At the same time, because the assembly process requires multiple steps and the collaboration of multiple workers, it not only increases the workload but may also lead to problems such as poor fit, making it difficult to meet the current market demand for high efficiency.

[0004] Therefore, existing die-cutting and hardware assembly fixtures urgently need improvement. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a new type of bonding and bending assembly fixture with a simple structure and reasonable design. It can be formed by pressing and bending the upper and lower forming molds. Multiple products can be completed in each pressing, which can effectively save labor and reduce the workload of workers. It fundamentally improves the bonding method of traditional die-cutting and bending assembly.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a novel bonding and bending assembly fixture, including a lower pad, a lower die forming plate, an upper die forming plate, and a set of guide pillars. The lower die forming plate is disposed on the lower pad; the upper die forming plate is disposed above the lower die forming plate; the guide pillars pass through the lower die forming plate and are connected to the upper die forming plate; the lower die forming plate and the upper die forming plate are respectively provided with a plurality of bonding lower grooves and bonding upper grooves; a bonding cavity is formed between the bonding lower grooves and the bonding upper grooves; the sides of the bonding lower grooves and the bonding upper grooves are respectively provided with lower die forming blocks and upper die forming blocks, and a bending groove is also provided on the side of the upper die forming block; the lower die forming block is fixed to the lower pad by a bending insert; the lower die forming block, the upper die forming block, and the bending groove cooperate to complete the product bending. By pressing the lower die forming plate and the upper die forming plate together, the bonding of the entire product can be more uniform and the bending dimensions more accurate.

[0007] Furthermore, the fitting cavity is equipped with eight sets, which can effectively improve the assembly efficiency and reduce the slow efficiency of putting in less and taking out more.

[0008] Furthermore, during pressing, the bending insert ensures that the lower die forming block protrudes from the lower die forming plate and combines with the upper die forming plate, thereby achieving the bending effect.

[0009] Furthermore, a number of auxiliary guide posts are provided between the lower mold forming plate and the lower pad plate; a number of sleeves are provided on the lower pad plate; the lower end of the auxiliary guide post is located inside the sleeve, and the upper end is connected to the lower mold forming plate.

[0010] Furthermore, several springs are provided between the lower mold forming plate and the lower pad plate.

[0011] Furthermore, the lower mold forming plate and the lower pad are opened by springs. After the lower mold forming block is opened by springs, the lower mold forming block retracts into the lower mold forming plate. After the springs are pressed together, the lower mold forming block is guided into the bending groove, and the product is formed.

[0012] Furthermore, the lower mold forming plate is provided with guide post through holes, and the guide post passes through the guide post through holes; when the lower end of the guide post abuts against the lower pad plate, there is only a gap of one product thickness between the lower mold forming plate and the upper mold forming plate, and the spring is in a compressed state at this time.

[0013] Furthermore, the upper groove of the bonding surface is provided with several clearance grooves; the upper groove of the bonding surface is provided with several positioning protrusions. The clearance grooves prevent damage to the product periphery during the pressing process; the positioning protrusions guide and position the product during the slow pressing process.

[0014] Furthermore, the lower groove is provided with a fitting groove. The fitting groove provides positioning for product placement.

[0015] Furthermore, the upper mold forming plate is provided with several product upper end positioning grooves between the upper grooves. The product upper end positioning grooves provide positioning and protection for the bending structure at the upper end of the product, preventing product damage.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a novel bonding and bending assembly fixture, in which the product is placed inside the bonding cavity, enabling the entire product to be bonded with higher quality.

[0018] 2. This utility model provides a novel bonding and bending assembly fixture with a simple structure and reasonable design. The upper and lower forming templates clamp the product, and the upper and lower driving mechanism is connected to an external pressing machine. Multiple sets of products can be completed at one time, which effectively saves labor, reduces the workload of workers, and better meets the needs of production. Attached Figure Description

[0035] Specifically, the lower die forming plate 2 and the lower pad plate 1 are opened by the spring 13. After the lower die forming block 22 is opened by the spring 13, the lower die forming block 22 retracts into the lower die forming plate 2. After the spring 13 presses it closed, the lower die forming block 22 is guided into the bending groove 33 of the upper die forming plate 3. Together with the upper die forming block 32, the product bending is completed.
