Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber production, in particular to a shock absorber connecting rod stamping die. Background Art

[0002] The connecting rod of the shock absorber is a part that connects the shock absorber piston and the base. It plays the role of transmitting force and absorbing impact. The connecting rod of the shock absorber is usually made of metal and has a certain strength and toughness. The components of the shock absorber connecting rod mainly include a tube body, a connector and a connecting pin. Among them, the tube body is the main part of the connecting rod, which is used to transmit force. When the inner tube body of the connecting rod is produced, it is necessary to stamp one end of the tube body to form an inner folding limit part to be used as a limit positioning ring.

[0003] A Chinese patent with publication number CN218224219U was searched and disclosed a forming device for a shock absorber tube body.

[0004] The utility model includes a base, a frame arranged on the base, and a cold rolling die arranged on the frame. The cold rolling die includes a mounting seat slidably connected to the frame up and down, and a punching block arranged on the mounting seat. The bottom of the punching block is provided with a punching groove for the tube body to be inserted into the end of the tube body to form an inner folding limiter. When the punching block is located on the mounting seat, the punching groove is arranged in a flared structure. During processing, the central axis of the punching groove coincides with the axis of the tube body. The frame is provided with a driving member for the punching block to slide to the tube body and be inserted into the punching groove. The base is provided with a positioning member for positioning and installing the tube body. The present application has the effect of improving the processing efficiency of the tube body.

[0005] However, the patent still has the following problems: the device uses a cylinder to push the slider to move the tube body to the bottom of the stamping block for stamping. However, when the slider is pushed to a precise position by the cylinder, it is easy for the slider to be offset after moving due to the low manufacturing precision or wear of the parts and seals inside the cylinder. In addition, during the movement of the slider, the top of the tube is not limited and supported, which makes it easy for the top of the tube to shake and deviate, making it difficult for the clamping block to accurately position the tube, which in turn leads to poor results of the finished product after the tube is stamped. Utility Model Content

[0006] The purpose of the utility model is to provide a shock absorber connecting rod stamping die, which has the advantage of being able to provide a better positioning effect for pipe fittings, so that the quality of the finished product after the pipe fittings are stamped is better, and solves the problem that when stamping the pipe fittings inside the shock absorber connecting rod, the stamping effect is poor due to inaccurate positioning.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shock absorber connecting rod stamping die, comprising a stamping mechanism, a positioning mechanism is provided on one side of the stamping mechanism;

[0008] The stamping mechanism includes a mounting frame and a stamping cylinder. Two slide rails are fixed on the top of the mounting frame. A slider is slidably connected to the surface of the slide rail. A movable seat is fixed on the top of the slider. One end of the stamping cylinder passes through the movable seat and is fixed with a stamping block. A pushing cylinder is fixed on the top of the mounting frame.

[0009] The positioning mechanism includes a positioning cylinder and a mounting shell, a supporting frame is fixed to the surface of the positioning cylinder, a positioning frame is fixed to the surface of the supporting frame, a connecting frame is fixed to the surface of the positioning frame, a positioning roller is arranged on the surface of the connecting frame, a positioning baffle is fixed to the surface of the slide rail, a spring is fixed to the inner wall of the mounting shell, a positioning rod is fixed to one end of the spring, and a positioning groove is provided on the surface of the slider.

[0010] A surface on one side of the positioning rod is arranged in a semicircular structure.

[0011] The inner wall of the sliding block is provided with an installation cavity, and a metal sheet is fixed on the inner wall of the installation cavity.

[0012] The metal sheet is arranged in an arc-shaped structure, and a connecting groove is provided on the surface of the sliding block, and the connecting groove is connected with the installation cavity.

[0013] The positioning roller is rotatably connected to the surface of the connecting frame.

[0014] A buffer pad is fixed on the surface of the positioning baffle.

[0015] A controller is fixed on the surface of the mounting frame.

[0016] Compared with the prior art, the beneficial effects of this mold are as follows:

[0017] By setting the positioning mechanism, the positioning of the pipe fitting is more accurate during stamping. When the pipe fitting is located inside the positioning cylinder, the bottom of the pipe fitting can be positioned. The support frame, the connecting frame and the positioning roller are matched, and the positioning roller can position and support the middle position of the pipe fitting. The fixed positioning cylinder and the support frame also avoid the shaking and offset of the upper side of the pipe fitting due to the movement of the pipe fitting. When the push cylinder pushes the movable seat to move toward the pipe fitting, the slider can contact the surface of the positioning baffle, thereby preventing the slider from exceeding the moving distance. In the process of the movement of the slider, the positioning rod will contact the surface of the slider. At the same time, the positioning rod can enter the mounting shell through its own shape and compress the spring. When the slider contacts the surface of the positioning baffle, the positioning rod will be located on one side of the positioning groove. At this time, the spring will be able to rebound to make the positioning rod enter the inside of the positioning groove, thereby achieving the positioning effect of the slider, ensuring that the positioning cylinder, the pipe fitting and the stamping block can be located on the same axis.

DETAILED DESCRIPTION

[0023] See also Figure 1-4 , a shock absorber connecting rod stamping die, comprising a stamping mechanism 1, a positioning mechanism 2 is provided on one side of the stamping mechanism 1;

[0024] The punching mechanism 1 enables the pipe fitting to obtain a punching effect, and the positioning mechanism 2 enables the pipe fitting to be positioned more accurately during punching.

[0025] The stamping mechanism 1 includes a mounting frame 101 and a stamping cylinder 106. Two slide rails 102 are fixed on the top of the mounting frame 101. A slider 103 is slidably connected to the surface of the slide rail 102. A movable seat 105 is fixed to the top of the slider 103. The stamping cylinder 106 is fixed to the top of the movable seat 105. One end of the stamping cylinder 106 penetrates the movable seat 105 and is fixed with a stamping block 107. A pushing cylinder 104 is fixed on the top of the mounting frame 101. One end of the pushing cylinder 104 is fixedly connected to the surface of the movable seat 105.

[0026] The pushing cylinder 104 can push the movable seat 105 to move, and at the same time, the movable seat 105 can drive the stamping cylinder 106 to move toward the pushing cylinder 104, so that the operator can have enough space to place the pipe fittings. When the movable seat 105 moves, the slider 103 will slide on the surface of the slide rail 102 to improve the stability of the movable seat 105. After the pipe fittings are placed, the stamping cylinder 106 is started to make the stamping cylinder 106 push the stamping block 107 downward, so that the stamping block 107 stamps the end face of the pipe fitting to form an inward folding limit portion at the end.

[0027] The positioning mechanism 2 includes a positioning cylinder 201 and a mounting shell 207. A support frame 202 is fixed to the surface of the positioning cylinder 201. A positioning frame 203 is fixed to the surface of the support frame 202. A connecting frame 204 is fixed to the surface of the positioning frame 203. A positioning roller 205 is arranged on the surface of the connecting frame 204. A positioning baffle 206 is fixed to the surface of the slide rail 102. A connecting plate is fixed to the surface of the slide rail 102. The surface of the connecting plate is fixedly connected to the mounting shell 207. A spring 208 is fixed to the inner wall of the mounting shell 207. A positioning rod 209 is fixed to one end of the spring 208. A positioning groove 212 is provided on the surface of the slider 103.

[0028] When the pipe is located inside the positioning cylinder 201, the bottom of the pipe can be positioned. The support frame 202, the connecting frame 204 and the positioning roller 205 are matched. The positioning roller 205 can position and support the middle position of the pipe. The fixed positioning cylinder 201 and the supporting frame 202 also avoid the shaking and deviation of the upper side of the pipe due to the movement of the pipe. When the push cylinder 104 pushes the movable seat 105 to move toward the pipe, the slider 103 can contact the surface of the positioning baffle 206, thereby preventing the slider 103 from exceeding the moving distance. During the movement of the slider 103, the positioning rod 209 will contact the surface of the slider 103. At the same time, the positioning rod 209 can enter the mounting shell 207 through its own shape and compress the spring 208. When the slider 103 contacts the surface of the positioning baffle 206, the positioning rod 209 will be located on one side of the positioning groove 212. At this time, the spring 208 will be able to rebound to allow the positioning rod 209 to enter the inside of the positioning groove 212, thereby achieving the positioning effect of the slider 103 and ensuring that the positioning cylinder 201, the pipe fitting and the stamping block 107 can be located on the same axis.

[0029] Furthermore, one side surface of the positioning rod 209 is arranged in a semicircular structure;

[0030] The shape of the positioning rod 209 ensures that when its semicircular surface contacts the slider 103, the positioning rod 209 can force itself into the mounting shell 207, and also ensures that it can escape from the positioning groove 212 by its own shape.

[0031] Furthermore, a mounting cavity is provided on the inner wall of the slider 103, and a metal sheet 210 is fixed on the inner wall of the mounting cavity;

[0032] When the spring 208 rebounds and causes the positioning rod 209 to enter the positioning groove 212, the positioning rod 209 will collide with the metal sheet 210, thereby making a sound, thereby prompting the current position of the slider 103. After the metal sheet 210 on one side is collided twice and makes a sound, the stamping block 107 will be located on the same axis as the pipe fitting and the positioning cylinder 201.

[0033] Furthermore, the metal sheet 210 is arranged in an arc-shaped structure, and a connecting groove 211 is provided on the surface of the slider 103, and the connecting groove 211 is connected to the installation cavity;

[0034] Arranging the metal sheet 210 into an arc shape can increase its vibration area and air flow effect, thereby increasing the generation of sound, and the connecting groove 211 can enable the sound to be transmitted outward, thereby improving the prompt effect.

[0035] Further, the positioning roller 205 is rotatably connected to the surface of the connecting frame 204;

[0036] When the pipe is placed in the positioning cylinder 201 , the positioning roller 205 can rotate, thereby reducing the friction effect on the surface of the pipe, making it easier to place the pipe in the positioning cylinder 201 .

[0037] Furthermore, a buffer pad 213 is fixed on the surface of the positioning baffle 206;

[0038] The buffer pad 213 can provide a buffering effect for the slider 103 to avoid wear caused by rigid contact.

[0039] Furthermore, a controller 108 is fixed on the surface of the mounting frame 101, and the output end of the controller 108 is electrically connected to the input ends of the push cylinder 104 and the punch cylinder 106;

[0040] The controller 108 is enabled to operate the push cylinder 104 and the punch cylinder 106 .

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
