Description

Technical Field

[0001] This utility model relates to the field of material support technology for bending machines, and in particular to a multi-functional front material support for bending machines. Background Technology

[0002] A front support for a bending machine is a device used to support sheet metal, reducing operator workload, ensuring bending accuracy and consistency to a certain extent, and improving operational safety. Existing front supports with metal tabletops are prone to scratching sheet metal, are labor-intensive and noisy, and are only suitable for rough-machined workpieces with no surface finish requirements. While the tabletop can be customized, subsequent tabletop replacements require re-customization, increasing costs. Processing sheet metal also wears and scratches the tabletop, leading to a rough and uneven surface over time, further exacerbating scratches on subsequent workpieces. Height adjustment is done manually by rotating a handle and visually observing a nearby scale. This method relies entirely on operator experience, making it prone to human error. Even with a scale, it's difficult to guarantee precise repositioning after each mold or material change. This results in poor consistency in mass production, with fluctuations in bending angles and dimensions. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing metal table front support is only suitable for a single type of workpiece; it increases costs; it accelerates the wear of the front support itself; it has poor positioning accuracy; and it does not guarantee repeated positioning.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a multi-functional front support for a bending machine, comprising:

[0005] A countertop assembly, including an aluminum profile countertop base on which at least one of a brush, a nylon strip, or a ball-bearing countertop mounting plate is detachably mounted;

[0006] The height adjustment mechanism includes a trapezoidal lead screw, a guide column, a reducer, and a handwheel, wherein the trapezoidal lead screw is connected to the handwheel via the reducer;

[0007] The support frame includes a left support plate, a right support plate, a movable side sheet metal 1, a movable side sheet metal 2, and a transverse cover plate;

[0008] The side baffle assembly, including the front material support side baffle, is adjustablely mounted on the aluminum profile table base via a knob and a preset nut;

[0009] The indicating mechanism includes a first scale and a second scale.

[0010] The aluminum profile tabletop base has grooves on both sides for installing brushes, nylon strips, and ball bearing tabletop mounting plates.

[0011] The brush, nylon strip, or ball bearing table mounting plate is detachably fixed to the aluminum profile table base by screw tops.

[0012] The height adjustment mechanism also includes a screw nut fixing seat, a lower guide post fixing block, a guide post fixing seat 1, a guide post fixing seat 2, a guide sleeve pressure block, and a trapezoidal screw rod fixing bearing seat.

[0013] The handwheel drives the trapezoidal lead screw via a speed reducer.

[0014] The height of the front material support side baffle can be adjusted by a knob and a preset nut.

[0015] It also includes sliders and cam followers.

[0016] The second scale is set on the indicating scale sheet metal.

[0017] The aluminum profile tabletop base is equipped with a handle optical axis and a handle fixing sheet metal at one end.

[0018] The beneficial effects of this utility model are:

[0019] (1) The multi-functional table front support material of this utility model for bending machine uses nylon, brush and ball bearing table to take into account protection, smoothness and stability. Each of the three materials has its own advantages, and they can be used together to cope with various complex working conditions.

[0020] (2) The sampling system features a versatile and replaceable multi-functional worktop design that offers high adaptability and flexibility, and the worktop is easy to replace.

[0021] (3) The reasonable material combination makes the wear and tear occur on the replaceable nylon, brush and ball, which protects the metal structure of the front support body and reduces long-term maintenance costs.

[0022] (4) Excellent surface protection means that scrap and rework caused by scratches are almost completely eliminated, saving huge costs;

[0023] (5) By driving the built-in high-precision ball screw by the motor, the height position of the material support can be precisely controlled digitally. After the operator inputs the parameters on the CNC system, the screw will rotate a specific number of times to move the material support to the precise theoretical position, eliminating the error of manual adjustment.
