Description

Technical Field

[0001] This utility model relates to the field of metal sheet or rod processing technology, and in particular to a two-in-one manual bending mold. Background Technology

[0002] Manual bending tools are widely used in machining, hardware manufacturing and other fields for the plastic forming of metal bars, flat steel and other workpieces due to their simple structure and easy operation.

[0003] In actual processing, bending requirements are diverse. For example, it may be necessary to bend sharp right angles, smooth arcs with a specific radius, or even irregularly shaped parts. These different bending effects all depend on the specific structure of the core mold component in the bending die that is in direct contact with the workpiece.

[0004] This has resulted in the structure and function of the vast majority of manual bending tools in existing technology being highly fixed. A piece of equipment is usually designed to complete only one or a very similar type of bending task. Once the processing requirements change and exceed its design scope, the equipment becomes powerless.

[0005] Therefore, to meet diverse production needs, processing workshops or individual users have to purchase and store multiple specialized bending machines with different functions. This not only significantly increases the cost of equipment procurement and maintenance but also occupies a large amount of storage and workspace, greatly limiting overall processing efficiency and economy. Currently, there is a general lack of a solution in existing technologies that is compact, highly integrated, and can flexibly adapt to various bending tasks.

[0006] Therefore, this utility model proposes a two-in-one manual bending mold to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a two-in-one manual bending die, which aims to improve the existing two-in-one manual bending die's single function, poor versatility, and difficulty in flexibly accommodating bending tasks of workpieces of various specifications and shapes.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a two-in-one manual bending die, comprising: a base plate and a bending handle rotatably connected to the base plate; a multi-purpose die assembly detachably mounted on the base plate and a universal die assembly detachably mounted on the base plate to replace the multi-purpose die assembly.

[0010] The universal mold assembly includes a flat-bottomed bending slider slidably mounted on a base plate and a universal mold core mounted on the base plate. The flat-bottomed bending slider is also connected to the bending handle. By selectively installing two complementary components on the same basic platform, functional integration and expansion are achieved.

[0011] Preferably, it also includes a circular mold plate fixed to the base plate; the multi-purpose mold assembly also includes an angle limiting adjustment screw and an angle limiting fixing block, the angle limiting fixing block is installed on the main mold plate and cooperates with the circular mold plate to limit the bending angle.

[0012] Preferably, the multi-purpose mold assembly further includes a distance limit adjustment screw, a top block, and a rear clamping block, which are disposed on the main mold plate and are used to clamp and position the workpiece.

[0013] Preferably, the multi-purpose mold assembly further includes a first bending bearing disposed on the high bending slider, a mold sub-plate fixedly connected to the mold main board, and a mold height adjusting foot for adjusting the height of the mold main board.

[0014] Preferably, the mold core includes a first pointed mold core and a second pointed mold core; or, the mold core is at least one of a first round mold core, a second round mold core, a third round mold core, a fourth round mold core, a fifth round mold core, a sixth round mold core, a seventh round mold core, and an eighth round mold core.

[0015] Preferably, it also includes mold base fixing screws, and the universal mold assembly is fixed to the base plate by the mold base fixing screws.

[0016] Preferably, the universal mold assembly further includes a second bending bearing, a third bending bearing, and a cam bearing, all of which are rotatably connected between the bending handle and the flat-bottomed bending slider to drive the movement of the flat-bottomed bending slider.

[0018] Preferably, the universal mold assembly further includes a precision cylindrical pin and a smooth-headed screw core for fixing the universal mold core to the base plate.

[0019] Preferably, it further includes at least one positioning strip, which is one of a first positioning strip, a second positioning strip, a third positioning strip, a fourth positioning strip, a fifth positioning strip, and a sixth positioning strip, and the positioning strip can be installed on the base plate or the multi-purpose mold assembly; and it also includes a tightening screw that can be installed on the base plate or the multi-purpose mold assembly.

[0020] This utility model has the following beneficial effects:

[0021] 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-5 The present invention provides an embodiment of a two-in-one manual bending mold, which aims to solve the problems of existing manual bending tools having a single structure, fixed function, difficulty in meeting the bending needs of workpieces of various specifications and shapes, and poor versatility.

[0032] The two-in-one manual bending die includes a base plate 1 and a bending handle 202 rotatably connected to the base plate 1. The base plate 1 serves as the mounting platform for the entire device, on which a basic frame is integrated and two functionally different components can be detachably installed. These two components are a multi-purpose die component 2 and a universal die component 3. The multi-purpose die component 2 and the universal die component 3 can be detachably installed on the base plate 1, replacing the multi-purpose die component 2. Users can select one of the components to install according to different bending needs and complete the bending operation by operating the common bending handle 202. A circular die plate 201 is also fixed on the base plate 1. The surface of the circular die plate 201 is engraved with angle markings to provide an angle reference for bending operations. This allows a single device to achieve multiple bending functions by changing components, greatly improving the versatility and applicability of the device.

[0033] The two-in-one manual bending mold includes a multi-purpose mold assembly 2, which forms a detachable installation relationship with the base plate 1, thereby realizing modular switching of equipment functions.

[0034] When various bending operations are required, the multi-purpose mold assembly 2 is installed on the base plate 1. The structure of the multi-purpose mold assembly 2 includes a mold main plate 208 as its mounting base. A high bending slider 206 is slidably mounted on the mold main plate 208. The high bending slider 206 is connected to the bending handle 202 through a first bending bearing 207 mounted on it. When the bending handle 202 is operated, the high bending slider 206 reciprocates along the guide rail of the mold main plate 208, thereby applying bending force to the workpiece. A mold sub-plate 209 is also fixedly connected to the mold main plate 208. A mold height adjustment foot 223 for adjusting the height of the mold main plate 208 is also mounted on it to accommodate workpieces of different thicknesses.

[0035] To achieve precise bending control, the multi-purpose mold assembly 2 also integrates a dual angle and distance adjustment mechanism. The angle adjustment mechanism includes an angle limiting fixing block 204 and an angle limiting adjusting screw 203 mounted on the main mold plate 208. By rotating the angle limiting adjusting screw 203, the position of the angle limiting fixing block 204 can be precisely adjusted so that its tip is aligned with the corresponding angle scale on the circular mold plate 201, thereby preset and limiting the maximum bending angle. The distance adjustment mechanism includes a top block 211, a rear clamping block 212, and a distance limiting adjusting screw 210. The top block 211 and the rear clamping block 212 are set on the main mold plate 208 to clamp and position the workpiece before bending. The distance limiting adjusting screw 210 can be used to fine-tune the clamping position to ensure that the bending point is accurate.

[0036] To meet the requirements of different bending shapes, the main mold plate 208 also has a variety of mold cores that can be replaced and installed on the main mold plate 208. These mold cores include a first sharp corner mold core 213 and a second sharp corner mold core 214 for achieving sharp corner bending, and a number of round mold cores for achieving arc bending of different radii. Specifically, the round mold cores are at least one of the first round mold core 215, the second round mold core 216, the third round mold core 217, the fourth round mold core 218, the fifth round mold core 219, the sixth round mold core 220, the seventh round mold core 221, and the eighth round mold core 222. This replaceable mold core, combined with a precise angle and distance adjustment system, enables the multi-purpose mold assembly 2 to efficiently complete the precision bending processing of solid round steel, flat steel, and various irregular parts.

[0037] When it is necessary to bend round steel and flat steel irregular shapes, the aforementioned multi-purpose mold assembly 2 can be removed from the base plate 1 and replaced with the universal mold assembly 3. The universal mold assembly 3 is fixed to the base plate 1 by a mold base fixing screw 205. The core moving part of the universal mold assembly 3 is the flat-bottomed bending slider 304, which is slidably set on the base plate 1 and is also connected to the bending handle 202.

[0038] Its driving mechanism includes a second bending bearing 301, a third bending bearing 302, and a cam bearing 305. These three bearings are rotatably connected between the bending handle 202 and the flat-bottomed bending slider 304, forming an efficient force transmission path to ensure that when the bending handle 202 is operated, the flat-bottomed bending slider 304 can be driven to perform linear reciprocating motion smoothly and powerfully.

[0039] The universal mold assembly 3 also includes a rotary positioning plate 303 rotatably mounted on the base plate 1. The rotary positioning plate 303 is used to quickly limit the length of the workpiece. The universal mold core 306 is mounted on the base plate 1 and is fixed to the base plate 1 by a precision cylindrical pin 307 and a smooth screw mold core 308 to ensure that it remains stable during bending.

[0040] As a supplement to the auxiliary positioning and fastening functions of the entire device, the two-in-one manual bending die also includes at least one positioning strip that can be installed as needed and a tightening screw 10. The positioning strip is one of the first positioning strip 4, the second positioning strip 5, the third positioning strip 6, the fourth positioning strip 7, the fifth positioning strip 8 and the sixth positioning strip 9. These positioning strips can be installed on the base plate 1 or the multi-purpose mold assembly 2 for auxiliary positioning of workpieces of different shapes. The tightening screw 10 can be installed on the base plate 1 or the universal mold assembly 3 for auxiliary clamping or fixing of the workpiece in a specific process step.

[0041] Working principle: When using the multi-purpose mold assembly 2 for bending operations, firstly, according to the workpiece requirements, the corresponding mold core is installed on the main mold plate 208, such as the first pointed mold core 213 or the first round mold core 215. The working height is adjusted by the mold height adjustment foot 223. The workpiece to be processed is placed between the top block 211 and the rear clamping block 212. The first positioning strip 4 to the fourth positioning strip 7 can be used for auxiliary positioning. Then, the bending parameters are preset by the angle limit adjustment screw 203 and the distance limit adjustment screw 210. The operator turns the bending handle 202. The bending handle 202 drives the high bending slider 206 to slide along the main mold plate 208 through the first bending bearing 207, applying pressure to the workpiece until the angle limit fixing block 204 contacts the preset limit point on the round mold plate 201, thus completing a precise bending operation.

[0042] When switching to the universal mold assembly 3 for operation, first fix the relevant parts of the universal mold assembly 3 to the base plate 1 using the mold base fixing screws 205, and fix the universal mold core 306 using the precision cylindrical pins 307 and the smooth head screw mold core 308. Use the rotating positioning plate 303 to limit the length of the workpiece, and use the fifth positioning strip 8 and the sixth positioning strip 9 for auxiliary positioning. Operate the bending handle 202, which drives the flat bottom bending slider 304 to slide through the second bending bearing 301, the third bending bearing 302 and the cam bearing 305. The flat bottom bending slider 304 and the universal mold core 306 work together to bend the workpiece. The operator controls the bending angle by referring to the scale on the circular mold plate 201. If necessary, the tightening screw 10 can be used for reinforcement. By selectively installing the multi-purpose mold assembly 2 or the universal mold assembly 3 on the same base plate 1 platform, this utility model solves the problem of the fixed function of a single bending tool in the prior art and its inability to be compatible with multiple processing needs.
