Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hardware processing, in particular to a hardware stretching tool with uniform force. Background Art
[0002] In the hardware manufacturing process, the stretching process is an indispensable part. Hardware stretching is a processing technology that plastically deforms the hardware material through external force to obtain the required shape and size. In this process, tooling plays a vital role. It can help fix the hardware to prevent it from moving or deforming during the stretching process, and ensure the accuracy and efficiency of the processing. However, traditional hardware stretching tooling often has problems such as uneven force and poor clamping effect, resulting in unstable quality of the stretched hardware, and even defects such as deformation and cracking. This not only affects the appearance and performance of the product, but also increases production costs and maintenance difficulties. Utility Model Content
[0003] The utility model aims to provide a hardware stretching tool with uniform force, so as to solve the problems of uneven force and poor clamping effect in the hardware stretching tool mentioned in the background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A uniformly stressed hardware stretching tool comprises a stretching base, a fixed column is installed at one end of the top of the stretching base, a sliding column is installed at the top of the stretching base, and a fixed chuck with a U-shaped cross section is installed on the opposite side of the fixed column and the sliding column;
[0006] The top surface of the stretching base is provided with a movable slide groove, and the bottom surface of the sliding column is provided with a movable slide seat which is adapted to the cross-sectional size of the movable slide groove and slidably matched;
[0007] An adjusting screw is installed on the fixed column, and one end of the adjusting screw is rotatably connected to the sliding column through a rotating seat;
[0008] A movable clamping block is installed in the fixed clamping head, and a clamping hydraulic cylinder coaxially arranged with the movable clamping block is installed on the outer wall of the fixed clamping head.
[0009] Preferably, the cross-sections of the movable slide groove and the movable slide seat are both convex-shaped.
[0010] Preferably, an adjusting dial is coaxially mounted on one end of the adjusting screw away from the sliding column.
[0011] Preferably, a plurality of anti-slip protrusions arranged evenly and equidistantly are installed on the surface of the movable clamping block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. In this uniformly stressed hardware stretching tooling, the movable clamping block is installed in the fixed chuck and the clamping hydraulic cylinder is installed on the outer wall.

The adjusting screw installed on the fixed column and the rotating connection with the sliding column through the rotating seat enable the adjusting screw to drive the sliding column to slide on the stretching base to perform uniform stretching.
[0017] 2.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0031] Stretching tooling for hardware with uniform force, such as Figure 1-Figure 3As shown, it includes a stretching base 10, a fixed column 20 is installed at one end of the top of the stretching base 10, a sliding column 30 is installed on the top of the stretching base 10, and a fixed chuck 40 with a U-shaped cross-section is installed on the side opposite to the fixed column 20 and the sliding column 30; a movable slide 11 is opened on the top surface of the stretching base 10, and a movable slide seat 31 that is adapted to the cross-sectional size of the movable slide 11 and slidably matched is installed on the bottom surface of the sliding column 30; an adjusting screw 21 is installed on the fixed column 20, and one end of the adjusting screw 21 is rotatably connected to the sliding column 30 through a rotating seat 22; a movable clamping block 41 is installed in the fixed chuck 40, and a movable clamping block 41 is installed on the outer wall of the fixed chuck 40 There is a clamping hydraulic cylinder 42 coaxially arranged with the movable clamping block 41. Through the movable clamping block 41 installed in the fixed clamp 40 and the clamping hydraulic cylinder 42 installed on the outer wall, the movable clamping block 41 can clamp and loosen the hardware through the driving force of the hydraulic cylinder, which not only provides sufficient clamping force to ensure that the hardware will not loosen or fall off during the stretching process, but also makes the clamping operation more stable and reliable through hydraulic drive. The adjusting screw 21 installed on the fixed column 20 and the rotation connection with the sliding column 30 through the rotating seat 22 enable the adjusting screw 21 to drive the sliding column 30 to slide on the stretching base 10 to perform uniform stretching.
[0032] It is worth mentioning that the cross-sections of the movable slide groove 11 and the movable slide seat 31 are both convex-shaped, which makes the movement of the slide seat in the slide groove more stable and less prone to shaking or derailment. The convex-shaped cross-section design increases the contact area, improves the smoothness and reliability of sliding, thereby ensuring the stability and accuracy of the sliding column 30 during the adjustment process.
[0033] Furthermore, an adjusting dial 23 is coaxially mounted on one end of the adjusting screw 21 away from the sliding column 30, so that the operator can more conveniently rotate the adjusting screw 21. The adjusting dial 23 increases the rotation radius, reduces the operating force, and improves the convenience of operation. At the same time, the design of the dial also makes the adjustment process more intuitive and easy to control, and improves the accuracy of the adjustment.
[0034] Specifically, the surface of the movable clamping block 41 is provided with a plurality of anti-skid protrusions 43 arranged evenly and equidistantly. The anti-skid protrusions 43 are made of wear-resistant rubber material, and the height of the protrusions is 1-2 mm, which increases the friction between the clamping block and the hardware, and prevents the hardware from sliding or falling off during the stretching process. The wear-resistant rubber material has good elasticity and wear resistance, and can maintain the anti-skid effect for a long time. At the same time, the evenly and equidistant arrangement of the anti-skid protrusions 43 makes the clamping force distribution more uniform, and improves the stability and reliability of the clamping.
[0035] In addition, a servo reduction motor 50 is installed on the fixed column 20 and the sliding column 30. The output shaft of the servo reduction motor 50 is coaxially connected to the back of the fixed clamp 40, and the fixed clamp 40 can be rotated, so that the hardware can be rotated and adjusted as needed during the stretching process, thereby improving the flexibility and adaptability of the operation.
[0036] The working principle of this uniformly stressed hardware stretching tool is as follows: the operator starts the clamping hydraulic cylinder 42, and the driving force of the hydraulic cylinder pushes the movable clamp block 41 to move toward the fixed clamp head 40 until the movable clamp block 41 is tightly fitted with the hardware, ensuring that the hardware is firmly clamped to prevent the hardware from loosening or falling off during the stretching process. The adjusting screw 21 is rotated to make the sliding column 30 slide on the stretching base 10 through the rotating seat 22 between the adjusting screw 21 and the sliding column 30. According to the stretching requirements of the hardware, the position of the sliding column 30 is gradually adjusted until the required stretching distance is reached.
[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
