Description

Technical Field

[0001] This utility model relates to the field of metal bending technology, specifically a high-hardness metal bending and forming fixture. Background Technology

[0002] In the process of processing high-hardness metal parts, some parts need to be bent. This requires the use of a high-hardness metal part bending and forming fixture to hold the high-hardness metal parts and fix them in place.

[0003] In the "A High-Hardness Metal Part Bending and Forming Fixture" with authorization announcement number "CN218532576U", a first fixed clamp and a second fixed clamp are symmetrically arranged, and the second fixed clamp is slidably connected to a fixed rod. The fixed block compresses the second fixed clamp through a return spring, causing the second fixed clamp to move downward. The second fixed clamp cooperates with the first fixed clamp to clamp and fix the workpiece. Limiting devices are provided on the outside of the first and second fixed clamps to fix their positions, thereby improving the workpiece fixing stability. However, during use, the operator needs to control and pull the baffle 86. The high-hardness metal part is clamped between the first and second fixing clamps before the control baffle 86 can be moved closer to the mounting frame 81 and mounting bracket 82. Only then can the locking block 87 at the end of the mounting bracket 82 be inserted into the slot of the baffle 86. This is cumbersome to use. At the same time, when the first and second fixing clamps clamp and fix the workpiece, the high-hardness metal part is between the first and second fixing clamps, but the position of the high-hardness metal part on both sides of the first and second fixing clamps cannot be limited. The high-hardness metal part will rotate between the first and second fixing clamps, resulting in poor fixing effect. Utility Model Content

[0004] The purpose of this invention is to provide a high-hardness metal part bending and forming fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-hardness metal part bending and forming fixture, comprising a first fixing clamp and a second fixing clamp, wherein the first fixing clamp is disposed below the second fixing clamp and the first fixing clamp and the second fixing clamp are slidable relative to each other, a baffle is elastically slidably mounted at one end of the first fixing clamp, a slot is provided at equal intervals on one side of the baffle, a first extrusion slope is provided at one bottom corner of the baffle corresponding to the slot, a block is fixedly mounted at one end of the second fixing clamp, a second extrusion slope is provided at the bottom corner of the block away from the second fixing clamp, the second extrusion slope is in extrusion contact with the first extrusion slope, positioning bolts are symmetrically mounted between one end of the first fixing clamp and the second fixing clamp, and the metal part is located between the two positioning bolts.

[0006] As a further preferred embodiment of this technical solution, a first limiting rod is symmetrically fixedly installed in the middle of the second fixing clamp, and a first limiting hole is symmetrically opened in the middle of the first fixing clamp, with the first limiting rod and the first limiting hole being slidably connected.

[0007] As a further preferred embodiment of this technical solution, a first reset spring is sleeved on the outer side of the first limiting rod, one end of the first reset spring is fixedly connected to the second fixing clamp, and the other end of the first reset spring is fixedly connected to the first fixing clamp.

[0008] As a further preferred embodiment of this technical solution, a second limiting hole is symmetrically provided at one end of the first fixing clamp, and a second limiting rod is symmetrically fixedly installed at the bottom end of the baffle. The second limiting rod is slidably connected to the second limiting hole. The end of the second limiting rod away from the baffle is located inside one end of the first fixing clamp. A second return spring is sleeved on the outer side of the end of the second limiting rod away from the baffle. One end of the second return spring is fixedly connected to the end of the second limiting rod away from the baffle, and the other end of the second return spring is fixedly connected to the inner wall of the end of the first fixing clamp.

[0009] As a further preferred embodiment of this technical solution, bolt holes are provided at equal intervals at the ends of both the first fixing clamp and the second fixing clamp. The positioning bolt passes through the bolt holes on the first fixing clamp and is installed on the first fixing clamp. The positioning bolt passes through the bolt holes on the second fixing clamp and is slidably connected to the bolt holes on the second fixing clamp.

[0011] As a further preferred embodiment of this technical solution, both the first and second fixing clips have a stop block integrally provided on their opposite sides.

[0012] This utility model provides a high-hardness metal part bending and forming fixture, which has the following beneficial effects:

[0013] (1) This utility model places the metal part between the first fixed clamp and the second fixed clamp. By relatively pressing the first fixed clamp and the second fixed clamp, the first limiting rod will slide inside the first limiting hole. During this process, the first return spring is in a compressed state, and the second pressing slope at the bottom corner of one end of the card block on the second fixed clamp will press the first pressing slope at the bottom corner of the card slot, which will drive the second limiting rod at the bottom of the baffle to slide inside the second limiting hole. This is used to control the baffle to move away from the first fixed clamp. The second return spring will be in a compressed state. When the card block moves to the card slot position at the designated position, the push of the second limiting rod end by the second return spring will drive the second limiting rod to slide in the opposite direction inside the second limiting hole, thereby driving the card block to slide into the card slot, realizing the automatic positioning assembly between the first fixed clamp and the second fixed clamp. The first fixed clamp and the second fixed clamp cooperate to clamp and fix the metal part.

[0014] (2) This utility model pre-installs two positioning bolts between two bolt holes on the first fixing clamp to adjust the distance between the two positioning bolts to match the distance between the two ends of the metal part. When the metal part is clamped and fixed, the top of the positioning bolt will slide inside the bolt hole on the second fixing clamp. The two positioning bolts position the two sides of the metal part to prevent the two sides of the metal part from being restricted, and prevent the metal part from rotating between the first fixing clamp and the second fixing clamp, thereby improving the stability of fixing the metal part.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a high-hardness metal part bending and forming fixture includes a first fixing clamp 1 and a second fixing clamp 2. The first fixing clamp 1 is positioned below the second fixing clamp 2, and the first fixing clamp 1 and the second fixing clamp 2 can slide relative to each other. A baffle 4 is elastically slidably installed at one end of the first fixing clamp 1. A slot 5 is equidistantly provided on one side of the baffle 4, allowing for selection of a suitable slot 5 for clamping according to the different specifications of the metal part, thus improving the range of applications. A first extrusion slope 6 is provided at the bottom corner of the baffle 4 corresponding to the slot 5. A clamping block 7 is fixedly installed at one end of the second fixing clamp 2. A second extrusion slope 8 is provided at the bottom corner of the end of the clamping block 7 away from the second fixing clamp 2, and the second extrusion slope 8 is in extrusion contact with the first extrusion slope 6. Positioning bolts 9 are symmetrically installed between one end of the first fixing clamp 1 and the second fixing clamp 2. The metal part is positioned between the two positioning bolts 9. The metal part is placed in the first fixing clamp 1 and the second fixing clamp 2. Between the fixing clamps 2, by relatively pressing the first fixing clamp 1 and the second fixing clamp 2, the second pressing slope 8 at the bottom corner of one end of the locking block 7 on the second fixing clamp 2 will press the first pressing slope 6 at the bottom corner of the slot 5, which will drive the baffle 4 to move away from the first fixing clamp 1. When the locking block 7 moves to the designated position of the slot 5, it can be automatically controlled to slide the locking block 7 into the slot 5, realizing the automatic positioning and assembly between the first fixing clamp 1 and the second fixing clamp 2. The first fixing clamp 1 and the second fixing clamp 2 cooperate to clamp and fix the metal part. When clamping and fixing the metal part, two positioning bolts 9 are pre-installed between the two bolt holes 16 on the first fixing clamp 1 to adjust the distance between the two positioning bolts 9 to match the distance between the two ends of the metal part. The two positioning bolts 9 are used to position the two sides of the metal part to prevent the two sides of the metal part from being restricted, and to prevent the metal part from rotating between the first fixing clamp 1 and the second fixing clamp 2, thereby improving the stability of fixing the metal part.

[0022] like Figures 1 to 4 As shown, a first limiting rod 10 is symmetrically fixedly installed in the middle of the second fixing clamp 2, and a first limiting hole 11 is symmetrically opened in the middle of the first fixing clamp 1. The first limiting rod 10 is slidably connected to the first limiting hole 11. A first return spring 12 is sleeved on the outside of the first limiting rod 10. One end of the first return spring 12 is fixedly connected to the second fixing clamp 2, and the other end of the first return spring 12 is fixedly connected to the first fixing clamp 1.

[0023] By relatively pressing the first fixing clamp 1 and the second fixing clamp 2, the first limiting rod 10 will slide inside the first limiting hole 11. During this process, the first return spring 12 is in a compressed state. After the positioning of the card slot 5 on the card block 7 is canceled, the first fixing clamp 1 and the second fixing clamp 2 will be controlled to move away from each other by the reset of the first return spring 12, and the clamping and fixing of the metal part will be canceled.

[0024] like Figures 1 to 4 As shown, a second limiting hole 13 is symmetrically opened at one end of the first fixing clamp 1, and a second limiting rod 14 is symmetrically fixedly installed at the bottom end of the baffle 4. The second limiting rod 14 is slidably connected to the second limiting hole 13. The end of the second limiting rod 14 away from the baffle 4 is located inside one end of the first fixing clamp 1. A second return spring 15 is sleeved on the outer side of the end of the second limiting rod 14 away from the baffle 4. One end of the second return spring 15 is fixedly connected to the end of the second limiting rod 14 away from the baffle 4, and the other end of the second return spring 15 is fixedly connected to the inner wall of the end of the first fixing clamp 1.

[0025] When the first fixing clamp 1 and the second fixing clamp 2 are pressed relative to each other, the second limiting rod 14 at the bottom of the baffle 4 will slide inside the second limiting hole 13 to control the baffle 4 to move away from the first fixing clamp 1. The second return spring 15 will be in a compressed state. When the card block 7 moves to the card slot 5 at the designated position, the push of the end of the second limiting rod 14 by the second return spring 15 will cause the second limiting rod 14 to slide in the opposite direction inside the second limiting hole 13, thereby causing the card block 7 to slide into the card slot 5, realizing the automatic positioning and assembly between the first fixing clamp 1 and the second fixing clamp 2.

[0026] like Figures 1 to 4 As shown, bolt holes 16 are equidistantly provided at the ends of the first fixing clamp 1 and the second fixing clamp 2. The positioning bolt 9 passes through the bolt hole 16 on the first fixing clamp 1 and is installed on the first fixing clamp 1. The positioning bolt 9 passes through the bolt hole 16 on the second fixing clamp 2 and is slidably connected to the bolt hole 16 on the second fixing clamp 2.

[0027] Two positioning bolts 9 are pre-installed between the two bolt holes 16 on the first fixing clamp 1 to adjust the distance between the two positioning bolts 9 to match the distance between the two ends of the metal part. The distance between the two positioning bolts 9 can be adjusted according to the size of the metal part to achieve positioning of metal parts of different sizes.

[0028] like Figures 1 to 4 As shown, rubber pads 17 are fixedly installed on the opposite ends of the first fixing clamp 1 and the second fixing clamp 2, which can improve the stability of the workpiece fixing.

[0029] like Figures 1 to 4As shown, the first fixing clip 1 and the second fixing clip 2 are both integrally provided with a stop block 3 on their opposite sides.

[0030] The stop block 3 can be set to limit the workpiece and restrict the clamping depth of the metal part.

[0031] This utility model provides a high-hardness metal part bending and forming fixture, the specific working principle of which is as follows:

[0032] When the device is in use, the metal part is placed between the first fixed clamp 1 and the second fixed clamp 2. By relatively pressing the first fixed clamp 1 and the second fixed clamp 2, the first limiting rod 10 will slide inside the first limiting hole 11. During this process, the first return spring 12 is in a compressed state, and the second pressing slope 8 at the bottom corner of the locking block 7 on the second fixed clamp 2 will press the first pressing slope 6 at the bottom corner of the slot 5, which will cause the second limiting rod 14 at the bottom of the baffle 4 to slide inside the second limiting hole 13, which is used to control the baffle 4 to move away from the first fixed clamp 1. The second return spring 15 will be in a compressed state. When the locking block 7 moves to the slot 5 position of the designated position, the push of the end of the second limiting rod 14 by the second return spring 15 will cause the second limiting rod 14 to slide in the opposite direction inside the second limiting hole 13, thereby causing the locking block 7 to slide into the slot 5, realizing the automatic positioning and assembly between the first fixed clamp 1 and the second fixed clamp 2. The first fixed clamp 1 and the second fixed clamp 2 cooperate to clamp and fix the metal part.

[0033] When clamping and fixing the metal part, two positioning bolts 9 are pre-installed between the two bolt holes 16 on the first fixing clamp 1 to adjust the distance between the two positioning bolts 9 to match the distance between the two ends of the metal part. When clamping and fixing the metal part, the top of the positioning bolts 9 will slide inside the bolt holes 16 on the second fixing clamp 2. The two positioning bolts 9 are used to position the two sides of the metal part to prevent the two sides of the metal part from being restricted, and to prevent the metal part from rotating between the first fixing clamp 1 and the second fixing clamp 2, thereby improving the stability of fixing the metal part.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
