Description

Technical Field

[0001] This utility model relates to the field of stamping and bending technology, and more specifically, to a hardware stamping and bending equipment with a buffer structure. Background Technology

[0002] Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting. They are used to fix things, process things, and decorate. In the production process of hardware, it is necessary to bend the hardware, and stamping equipment is used to stamp and bend the hardware.

[0003] Among them, the bending equipment for producing stamping dies disclosed in application number CN202322803136.3 is also an increasingly mature technology. First, a limiting groove is set inside the limiting plate, and a locking block is set on the bending die. A buckle is fixed on the locking block. The locking block is embedded into the inside of the limiting plate, and the buckle is rotated open inside the limiting groove, thereby fixing the bending die and the limiting plate, increasing the stability of the bending die, and allowing the bending die to be replaced during the use of the equipment. An installation column is installed on the fixing block 2, and an installation hole is set below the template. Since the template itself is very heavy, the template can be fixed on the installation column. At the same time, the template can be replaced according to the required shape, so that the equipment can use different types of bending parts.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist: This type of bending equipment requires different molds to be changed for different hardware parts with different bending angles and shapes, which reduces efficiency. Moreover, the workpiece to be bent is not fixed during processing, which may cause displacement of the workpiece when bending. Utility Model Content

[0005] The purpose of this invention is to provide a hardware stamping and bending equipment with a buffer structure to solve the problems mentioned in the background art, such as reduced efficiency due to changing different molds and lack of fixed limit on the parts to be bent.

[0006] This utility model embodiment provides a hardware stamping and bending equipment with a buffer structure, including an angle adjustment device, a bending device and a clamping device; The angle adjustment device includes a long groove at the top center of the worktable, with buffer blocks symmetrically arranged inside the long groove. A mounting box is located at the top of each buffer block, and L-shaped plates are symmetrically arranged inside the mounting box. Adjustment plates are hinged to the opposite ends of the L-shaped plates via hinges. Multiple locking seats are located on the back of the end of the adjustment plate away from the hinge. An N-shaped block, representing the telescopic end of an electric telescopic rod, is fitted around each locking seat. Multiple fixing holes are located at the top of each L-shaped plate, and the fixing end of the electric telescopic rod is located inside these fixing holes. A set of adjustment plates forms a V-shaped structure, and the dimensions of the mounting box are adapted to the long groove.

[0007] In this embodiment, the telescopic rod of the electric telescopic rod has a self-locking property after moving to the appropriate length. Since the N-shaped block of the telescopic end of the electric telescopic rod is sleeved on the locking seat on the back of the adjusting plate, and the opposite ends of the adjusting plate are hinged, the adjusting plate is tilted according to the telescopic adjustment of the telescopic end of the electric telescopic rod, thereby forming the required angle. The buffer block supports and buffers the mounting box. The mounting box is located at the top of the buffer block, which facilitates the replacement of lower templates of different shapes.

[0008] In one embodiment of this utility model, the bending device includes an N-shaped frame at the top of the workbench, a cylinder at the middle of the top of the N-shaped frame, the piston end of the cylinder passing through the N-shaped frame and connected to a lifting plate through a convex disc, and an upper template being threadedly connected to the bottom of the lifting plate by screws.

[0009] In this solution, the piston end of the cylinder has a self-locking property after moving to the appropriate length. The piston end of the cylinder pushes the lifting plate to rise and fall. The lifting plate drives the upper template to apply pressure to the hardware, completing the bending operation. The N-type frame provides support for the components driven by the piston end of the cylinder. The upper template is connected by screw threads, which facilitates the installation or removal of the upper template and makes it easy to replace upper templates of different shapes. It can be used in conjunction with the lower template to perform multiple types of bending equipment in one machine, reducing the burden on the workers.

[0010] In one embodiment of this utility model, the clamping device includes supports on both sides of the front and back of the workbench, a lower roller rotatably disposed between the supports, an upper roller rotatably disposed on the top of the lower roller at the N-shaped frame, and sliding grooves are provided on the inner side walls at both ends of the N-shaped frame, with both ends of the upper roller located inside the sliding grooves.

[0011] In this solution, the lower roller is supported by a support, and the hardware is placed between the lower roller and the upper roller to achieve the clamping operation of the hardware. The sliding groove makes it convenient for the upper roller to adjust the height to clamp hardware of different thicknesses.

[0012] In one embodiment of this utility model, guide grooves are provided in the middle of the inner two side walls of the N-shaped frame, guide blocks are provided inside the guide grooves, and the guide blocks are connected to the two side walls of the lifting plate. The piston end of the cylinder is sleeved through the outside of the N-shaped frame.

[0013] In this design, the stability of the lifting plate during movement is ensured by the guide block sliding along the inside of the guide groove, and the sleeve reduces the wear between the piston end of the cylinder and the N-type frame.

[0014] In one embodiment of this utility model, the workbench is provided with support legs at all four corners of its bottom end and with reinforcing ribs in the middle, and the bottom end of each support leg is provided with a caster wheel with a wheel brake.

[0015] In this design, the support legs provide height and stability to the workbench, the reinforcing ribs increase the structural strength of the support legs, the casters facilitate flexible movement of the equipment, and the wheel brakes are locked to ensure the safety of the equipment.
