Description

Technical Field

[0001] This utility model belongs to the field of metal parts processing, and in particular relates to a metal parts bending device. Background Technology

[0002] In modern industrial manufacturing, metal parts are widely used in many industries such as machinery manufacturing, automotive, and aerospace due to their excellent physical properties. Bending, as a key processing technology for forming metal parts, has a direct impact on the assembly and performance of subsequent products due to its processing quality and efficiency.

[0003] Traditional bending devices typically have fixed, non-removable pressure heads. However, some bending devices use bolts to secure the pressure head to the corresponding position on the bending machine. This installation method makes disassembling and replacing the pressure head complex, hinders the rapid switching between different pressure head specifications to meet diverse bending needs, and significantly reduces production efficiency. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a metal bending device, which aims to solve the problem that existing metal bending devices are difficult to quickly switch between different specifications of pressure heads to meet diverse bending needs, thus greatly reducing production efficiency.

[0005] The present invention adopts the following technical solution:

[0006] The metal bending device includes a machine base, a column on the machine base, a top seat on the column, a bending cylinder on the top seat, a fixed seat on the drive shaft of the bending cylinder via a connecting seat, and a clamping seat on the fixed seat via a fixing assembly. Both the fixed seat and the clamping seat have opposing clamping grooves, and a bending pressure head is provided in the clamping grooves. The fixed seat has blocking assemblies at both ends corresponding to the bending pressure head. The blocking assemblies include rotatably mounted blocking blocks, and a linkage rod is provided between the blocking blocks. The fixed seat has a pair of upper and lower locking blocks corresponding to the linkage rod, and one of the blocking blocks also has a blocking rocker arm. A bending seat is provided on the machine base directly opposite the bending pressure head.

[0007] Furthermore, a positioning strip is formed in the clamping groove, and a matching positioning groove is opened on the upper part of the bending press head corresponding to the positioning strip.

[0008] Furthermore, the fixing assembly includes a pull rod mounted above the clamp, the pull rod extending out of the fixing seat and rotatably equipped with a cam, the cam having a rotating rod, and the pull rod also having a matching spring fitted on it.

[0009] Furthermore, a base is provided below the bending seat, and the base is fixedly installed on the machine platform by bolts. A V-groove is opened on the bending seat.

[0010] The beneficial effects of this utility model are:

[0011] 1. With the fixing assembly consisting of cam, pull rod and spring, the operator only needs to rotate the cam to quickly loosen or clamp the clamp, realizing the quick replacement of the bending head. Compared with the traditional device, it greatly shortens the mold change time and improves production efficiency.

[0012] 2. The cooperation between the positioning strip and the positioning groove, as well as the positioning effect of the V-groove of the bending seat on the metal parts, can ensure the accurate positioning of the bending head and the metal parts during the processing, effectively improving bending accuracy and reducing scrap rate.

[0013] 3. The blocking component, through the design of the linkage rod and the locking block, can block the forward and backward movement of the bending head during the bending process, thereby enhancing the stability of the bending head. Attached Figure Description

[0016] Figure 3 This is a schematic diagram of the blocking component provided by this utility model. Detailed Implementation

[0017] To make the purpose, technical solution, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-3As shown, the metal bending device includes a machine base 1, a column 2 on the machine base 1, a top seat 3 on the column 2, a bending cylinder 4 on the top seat 3, a fixed seat 5 on the drive shaft of the bending cylinder 4 via a connecting seat 41, a clamping seat 6 on the fixed seat 5 via a fixing assembly, and clamping slots 7 on both the fixed seat 5 and the clamping seat 6. A bending pressure head 8 is provided in the clamping slots 7. The fixed seat 5 is provided with blocking assemblies at both ends corresponding to the bending pressure head 8. The blocking assembly includes a rotatably mounted blocking block 9. A linkage rod 10 is provided between the blocking blocks 9. The fixed seat 5 is provided with a pair of upper and lower locking blocks 11 corresponding to the linkage rod. One of the blocking blocks is also provided with a blocking rocker arm 12. A bending seat 13 is provided on the machine base 1 directly opposite the bending pressure head 8.

[0021] When using this device to bend metal parts, the linkage rod engages in the upper clamping block, and the blocking block moves away from the clamping groove on the same side to create clearance. First, select a suitable bending head according to the metal part to be bent, place the bending head into the clamping groove of the fixed seat and clamping seat as required, and then use the blocking component to block the front and rear ends of the bending head to lock the bending head.

[0022] When the front and rear blocking components block the front and rear ends of the bending head, first rotate the blocking rocker arm downwards to make the two blocking blocks rotate downwards. After the linkage rod rotates and engages with the lower locking block, the two blocking blocks are precisely positioned at the front and rear end faces of the bending head, preventing the head from moving axially through mechanical limiting.

[0023] As a preferred structure, such as Figure 2-3 The fixing assembly includes a pull rod 14 mounted above the clamp 6. The pull rod 14 extends out of the fixing seat 5 and is rotatably provided with a cam 15. The cam 15 is provided with a rotating rod 16, and a matching spring 17 is also sleeved on the pull rod 14.

[0024] When the rotating rod drives the cam to rotate and move the pull rod to the left, the spring is compressed, generating an elastic restoring force that forces the clamp to move closer to the fixed seat. Before installing the bending head, the cam is in its initial position, and the spring naturally extends, leaving an assembly gap between the fixed seat and the clamp to facilitate the insertion of the head. After the head is in place, rotating the cam compresses the spring, and the pull rod pulls the clamp to press the fixed seat tightly, achieving rigid clamping of the head.

[0025] As a specific structure, a positioning strip 18 is formed in the clamping groove 7, and a matching positioning groove 19 is opened on the upper part of the bending head 8 corresponding to the positioning strip.

[0026] When the bending head needs to be pushed into the clamping groove, the positioning grooves on both sides of the bending head must be aligned with the positioning strip before the bending head can be pushed into the clamping groove. The cooperation between the positioning strip and the positioning groove ensures accurate installation of the bending head, and further makes the installation of the bending head more secure and stable.

[0027] In addition, such as Figure 1 A base 20 is provided below the bending seat 13. The base 20 is fixedly installed on the machine base 1 by bolts 21. A V-groove 22 is opened on the bending seat 13.

[0028] After installing the appropriate bending head, place the metal part on the V-groove of the bending seat, start the bending cylinder, and the drive shaft of the bending cylinder will drive the fixed seat and the bending head to move downward to perform the bending operation on the metal part.

[0029] The V-groove design in this structure allows for better contact with the metal parts, providing stable support during bending and enabling the metal parts to bend at a predetermined angle, thus improving the quality and stability of bending.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
