Description

Technical Field

[0001] The utility model relates to a rolling groove forming machine. Background Art

[0002] In the conventional processing of air conditioning pipes, an annular groove needs to be processed at the end of the air conditioning pipe before bending. Since the annular groove is currently processed by turning, the wall thickness at the annular groove will become thinner due to the removal of a large amount of material. In order to meet the strength requirements of the workpiece, only pipes with larger wall thickness can be used for processing, which leads to the problem of high material cost. Utility Model Content

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1: See Figure 1-4 , a groove rolling machine, comprising a frame 1, a supporting rotating mechanism 2, a clamping rotating mechanism 3 and a groove rolling wheel feeding mechanism 4;

[0021] See also Figure 8-9 , the supporting rotating mechanism 2 and the clamping rotating mechanism 3 are respectively installed on the left and right sides of the frame 1;

[0022] See also Figure 8-9The supporting rotating mechanism 2 includes a motor 2-1, a support 2-2, a driving wheel 2-3 and a driven wheel 2-4; the support 2-2 is fixed on the frame 1, the driving wheel 2-3 and the driven wheel 2-4 are both rotatably mounted on the support 2-2 and are parallel to each other and arranged close to each other at the same height. The output end of the motor 2-1 is fixedly connected to the driving wheel 2-3 and is used to drive the driving wheel 2-3 to rotate. When working, the motor 2-1 drives the driving wheel 2-3 to rotate on the support 2-2. The end of the pipe (i.e. Figure 1-3 The left end of the middle pipe is supported by the driving wheel 2-3 and the driven wheel 2-4 at the same time. When the driving wheel 2-3 rotates, the friction drives the pipe to rotate together. Since the end of the pipe is supported by the driving wheel 2-3 and the driven wheel 2-4, the rotation center is located. During operation, the driving wheel 2-3 is driven by the motor 2-1 to rotate actively, and the driven wheel 2-4 rotates with the pipe.

[0023] See also Figure 8-9 The clamping and rotating mechanism 3 includes a bracket 3-1 and a pneumatic rotary chuck 3-2; the bracket 3-1 is fixed on the frame 1, and the pneumatic rotary chuck 3-2 is rotatably mounted on the bracket 3-1. The pneumatic rotary chuck 3-2 is used to automatically clamp the pipe concentrically, and since the pneumatic rotary chuck 3-2 is rotatably mounted on the bracket 3-1, the pneumatic rotary chuck 3-2 can rotate freely on the bracket 3-1. Specifically, the pneumatic rotary chuck 3-2 belongs to the existing technology and is directly purchased and assembled, so it is not described in detail.

[0024] See also Figure 8-9 In this embodiment, the pneumatic rotary chuck 3-2 is rotatably mounted on the bracket 3-1 through the bearing 3-3. When the left end of the pipe is driven by the support rotation mechanism 2 to rotate at a fixed point, the pipe is clamped by the pneumatic rotary chuck 3-2 and rotated on the bracket 3-1. The pipe is in a horizontal state and supported on the left and right sides and rotates centered, which can ensure that the rotation direction of the pipe remains unchanged during processing, will not be eccentric or biased, and always rotates concentrically, thereby ensuring the accuracy of the forming position and the forming shape.

[0025] See also Figure 10-11The grooved wheel feeding mechanism 4 includes a portal frame 4-1, a grooved wheel 4-2, a guide seat 4-3 and a drive cylinder 4-4; the guide seat 4-3 is slidably matched with the portal frame 4-1 and can be driven up and down by the drive cylinder 4-4; the grooved wheel 4-2 is rotatably mounted at the bottom of the guide seat 4-3; the grooved wheel 4-2 is located directly above the driving wheel 2-3 and the driven wheel 2-4; a workpiece limiting baffle 4-5 is fixedly arranged on the portal frame 4-1, and the workpiece limiting baffle 4-5 is used to block one end face of the pipe and limit the axial position to ensure the accuracy of the rolling position. When rolling into grooves, the drive cylinder 4-4 drives the guide seat 4-3 to move downward into position, and the grooved wheel 4-2 will squeeze the pipe in a rotating state, thereby realizing the circumferential rolling of the pipe into grooves to obtain an annular groove N. Since it is extrusion-molded, the thickness of the annular groove N basically does not change much, and the wall thickness thinning is very small and can be ignored, which can meet the strength requirements of the workpiece. Therefore, there is no need to use a pipe with a thickness thicker than the product (air-conditioning pipe) for processing. Therefore, compared with the existing turning processing method, it can greatly save material costs.

[0026] Specifically, see Fig.12 A U-shaped frame 4-32 is fixedly arranged at the bottom of the guide seat 4-3, and a grooved wheel 4-2 is rotatably mounted on the U-shaped frame 4-32. A convex ring portion 4-21 matching the annular groove N is provided on the outer circle of the grooved wheel 4-2.

[0027] See also Figure 10-11 The two sides of the door frame 4-1 are fixed with two guide rails 4-11; the guide seat 4-3 is provided with two guide grooves 4-31 which are respectively slidably matched with the two guide rails 4-11. The double-sided guide lifting of the guide seat 4-3 can improve the linear accuracy of the movement and ensure the depth and shape size accuracy of the annular groove N during molding.

[0028] See also Figure 10-11 The cross sections of the guide rail 4-11 and the guide groove 4-31 are both dovetail-shaped. The guide groove 4-31 of the guide seat 4-3 and the guide rail 4-11 in the door frame 4-1 will not derail when sliding against each other, and can maintain long-term stability and reliability.

[0029] See also Figure 10-11 The driving cylinder 4-4 can be a pneumatic telescopic cylinder or a hydraulic telescopic cylinder.

[0030] When this embodiment is used, the operation steps are as follows:

[0031] S10, first pass the pipe through the pneumatic rotary chuck 3-2 until the left end face of the pipe is blocked by the workpiece limit baffle 4-5 and axially positioned. At this time, the left end of the pipe is supported by the driving wheel 2-3 and the driven wheel 2-4 at the same time and centrally positioned;

[0032] S20, then start the pneumatic rotary chuck 3-2 to work and clamp the pipe, at which time the middle of the pipe is centrally located (see Figure 1-4 );

[0033] S30, start the motor 2-1 to drive the driving wheel 2-3 to rotate on the support 2-2, thereby driving the pipe to rotate in a centered manner, and the pneumatic rotary chuck 3-2 rotates on the support 3-1 together with the pipe. At this time, the pipe is supported on both sides to rotate and maintain concentric rotation;

[0034] S40, start the drive cylinder 4-4 to work and drive the guide seat 4-3 to move downward to the position, the groove rolling wheel 4-2 will squeeze the pipe in the rotating state, so that the pipe can be rolled into a groove in the circumferential direction to obtain an annular groove N, and then the processed part is obtained (see Figure 5-6 );

[0035] S50, first shut down the motor 2-1, then start the drive cylinder 4-4 and drive the guide seat 4-3 to move upward and reset to its position, at which time the grooved wheel 4-2 releases the processed workpiece and is located above it; then start the pneumatic rotary chuck 3-2 and release the processed workpiece; then pull the processed workpiece completely out of the pneumatic rotary chuck 3-2 to the right.

[0036] This embodiment can roll the pipe into a groove to obtain an annular groove N (see Figure 7 ), because it adopts rolling groove forming method instead of the existing turning processing method, the pipe will not be thinned by turning, and the pipe with the same thickness as the product design can be used for processing, so that the material cost is lower. At the same time, the utility model has the advantages of simple operation, accurate molding position, and high production efficiency during processing.

[0037] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1:

[0038] See also Figure 8-9 In addition, a semicircular positioning groove 2-21 is provided on the support 2-2 on the side facing the pneumatic rotary chuck 3-2; the driving wheel 2-3 and the driven wheel 2-4 are respectively located on the front and rear sides of the semicircular positioning groove 2-21.

[0039] The semicircular positioning groove 2-21 is used to further position and constrain the pipe during rolling into the groove, so as to prevent the pipe from slightly jumping in the front-to-back direction when the driving wheel 2-3 and the driven wheel 2-4 support and rotate, thereby affecting the forming accuracy.
