Description

Technical Field

[0001] This utility model relates to the field of hot-rolled spring processing technology, specifically an automatic standing device. Background Technology

[0002] In the hot-rolled spring manufacturing process, there is usually a standing process after tempering, which involves compressing the spring several times to eliminate deformation during use.

[0003] The traditional method involves manually placing the springs on a single-column or four-column hydraulic press for compression, and then manually removing the springs for framing. This is time-consuming and labor-intensive. Furthermore, the hydraulic press is a stand-alone design and cannot be used in conjunction with the tempering process, which causes inconvenience in terms of turnover and production. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-3 An automatic standing device includes a support base 1, a tempering furnace 2 at the upper end of the support base 1, a water cooling zone 21 at the upper end of the support base 1 and to the right of the tempering furnace 2, a conveyor chain 3 at the upper end of the support base 1 and to the right of the water cooling zone 21, a grating 4 on the conveyor chain 3, a robot 5 at the upper end of the support base 1, and two transfer frames 6 at the upper end of the support base 1. The two transfer frames 6 are symmetrically distributed on the support base 1 and can be used to place materials.

[0021] Please see Figure 2-3 The transfer frame 6 is equipped with two positioning cylinders 7, which are symmetrically distributed on each transfer frame 6. The positioning cylinders 7 are used to position the transfer frame 6. An electrical control box 8 is installed at the upper end of the support base 1, and a guardrail 9 is also installed at the upper end of the support base 1. The guardrail 9 is fixedly connected to the grating 4 and contacts the transfer frame 6. The guardrail 9 provides protection for the equipment. A gate 10 is installed on the guardrail 9, allowing easy access to the equipment's production chain. A hydraulic press 11 is installed on the support base 1.

[0022] Please see Figure 2-3 The hydraulic press 11 includes a hydraulic press body 111, a cooler 112 is installed on the support base 1, the cooler 112 is electrically connected to the hydraulic press body 111, and the cooler 112 is designed to cool the hydraulic press body 111. The hydraulic press body 111 is equipped with a pressure gauge 113, a protective door 114, a detection device 115, a guide rail 116, and a button box 117, and a touch screen 1171. The hydraulic press body 111 is designed to perform vertical compression processing on springs.

[0023] The specific implementation process of this utility model is as follows: During use, the spring tempering temperature is approximately 450℃. After the spring is tempered and removed from the furnace, it enters the cooling zone, where it is cooled to room temperature by a cold water spray from the water cooling zone 21. After leaving the cooling zone, the spring rolls down under its own gravity and stops on the conveyor chain 3 after being blocked by the material blocking device. The conveyor chain 3 moves to the left until the spring stops at the grating sensor of the grating 4. Two empty material transfer frames 6 are placed in, and the left and right positioning cylinders 7 extend to clamp and position the frames. After receiving a signal, the robot 5 automatically grabs the spring and moves it to the first loading position (position one is on the right, and position two is on the left) of the hydraulic press body 111. The moving mechanism of the main body 111 moves to the left, positioning station one as the compression station. The hydraulic press 111 then performs a compression operation, with the compression height and number of compressions adjustable according to the product. Simultaneously, robot 5 grabs the second spring and places it on station two of the hydraulic press 111. After the spring at station one of the hydraulic press 111 is compressed and station two is loaded, the moving mechanism moves to the right, positioning station two as the compression station. The hydraulic press then performs another compression operation. Simultaneously, robot 5 automatically unloads the springs from station one and frames them. The number of frames is determined by the spring size; for example, for a certain TR40 spring, the number of frames is 6 × 5 × 4 = 120. After the springs at station one are unloaded, robot 5 grabs the next spring on the tempering conveyor chain 3 and places it on station one of the hydraulic press 111.

[0024] Repeat steps 3 to 5, and the standing motion will proceed automatically.

[0025] As the number of springs increases until the frame is full, robot 5 starts using another transfer frame 6 for unloading. At this point, the positioning cylinder 7 of the full transfer frame 6 is released, the transfer frame 6 is removed, and a new empty transfer frame 6 is replaced.

[0026] After the transfer frame 6 is placed in, the left and right positioning cylinders 7 extend to clamp and position the transfer frame 6. The transfer frame 6 adopts a dual design, which can be replaced when one transfer frame 6 is full, without causing production interruption when changing the transfer frame 6. The robot 5 is a KUKA KR210 robot, and the spring gripping device adopts a three-pneumatic gripper to grip the inner ring of the spring. The hydraulic press body 111 station adopts a detachable disc seat design, and the cone in the middle is the spring positioning device, which can be replaced according to the inner diameter of the spring, etc., to prevent the spring from tilting when moving left and right, when the robot 5 is loading and unloading, and when compressing.
