[0024] 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.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a technical solution: a bending device for mudguard production, including a base plate 1, a lower mold body 2 fixedly connected to the top of the base plate 1, and a bending groove 3 chiseled on the top of the lower mold body 2; a fixing frame 4 fixedly connected to the top of the base plate 1, and an electric telescopic rod 5 embedded in the top of the fixing frame 4; an upper mold body 6 fixedly connected to the bottom of the electric telescopic rod 5, and the upper mold body 6 matches the bending groove 3; side connecting plates 9 fixedly connected to both ends of the lower mold body 2, and the bottom ends of a pair of side connecting plates 9 are connected to... A pulling and vibrating mechanism 10 is provided between the top ends of the base plate 1. A material ejection mechanism 11 is provided between the pulling and vibrating mechanism 10 and the top end of the base plate 1 and the bending groove 3. A pair of T-shaped movable rods 7 are provided on the top of the fixed frame 4, and a pair of through holes are drilled on the top end of the fixed frame 4. The bottom ends of the pair of T-shaped movable rods 7 pass through the pair of through holes and are fixedly connected to the top end of the upper mold body 6. A first spring 8 is sleeved on the outer wall of the pair of T-shaped movable rods 7, and the two ends of the first spring 8 are fixedly connected to the inner top end of the T-shaped movable rod 7 and the top end of the fixed frame 4, respectively.

[0026] According to the overall structure of the device, the mudguard to be bent is placed on the lower mold body 2, and the electric telescopic rod 5 drives the upper mold body 6 to move downward. At the same time, a pair of T-shaped movable rods 7 move synchronously and compress the first spring 8, causing the lower mold body 2 to squeeze the mudguard slowly and deform inside the bending groove 3 under the buffering effect of the first spring 8, forming a mudguard bent part. After bending, the vibration loosening mechanism 10 drives a pair of side plates 9 and the lower mold body 2 to vibrate, so that the adhesion between the mudguard and the bending groove 3 is loosened by the vibration, making it less likely to stick together. Then, the material ejection mechanism 11 pushes the mudguard upward to facilitate the rapid discharge of the mudguard, so as to facilitate subsequent processing and improve processing efficiency.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, each of the pair of pulling and vibrating mechanisms 10 includes a telescopic cylinder 1001. The telescopic cylinder 1001 is fixedly connected to the bottom end of the base plate 1 via a pair of vertical plates. A square block 1002 is fixedly connected to the output end of the telescopic cylinder 1001, and a movable plate 1003 is fixedly connected to one end of the square block 1002. A pair of T-shaped lifting rods 1004 are provided at the bottom of the movable plate 1003, and a pair of round holes are drilled at the bottom end of the movable plate 1003. The top ends of the pair of T-shaped lifting rods 1004 pass through the pair of round holes and extend to the top of the movable plate 1003. The top ends of the pair of T-shaped lifting rods 1004 are fixedly connected to each other. A connecting plate 1006 is attached, and multiple impact hammer rods 1007 are fixedly connected to the top of the connecting plate 1006. The tops of the multiple impact hammer rods 1007 are in contact with the bottom of the side plate 9. A pair of T-shaped lifting rods 1004 are fitted with second springs 1005 on their outer walls. The two ends of the second springs 1005 are fixedly connected to the opposite sides of the connecting plate 1006 and the moving plate 1003, respectively. Multiple evenly distributed barrier strips 1008 are fixedly connected to the bottom of the side plate 9. The barrier strips 1008 are semi-cylindrical in shape, and the multiple barrier strips 1008 are located on one side of the impact hammer rods 1007.

[0028] By pulling the vibratory loosening mechanism 10, the telescopic cylinder 1001 pulls the moving plate 1003 downward toward the mold body 2 via the square block 1002, causing a pair of T-shaped lifting rods 1004 and the connecting plate 1006 to move synchronously. This causes multiple impact hammer rods 1007 to move along the bottom end of the side plate 9, and during the movement, they repeatedly come into contact with multiple obstacle bars 1008, causing the multiple impact hammer rods 1007 to be squeezed downward, separating from the bottom end of the side plate 9, and compressing the second spring 1005. Simultaneously, after separating from the barrier bar 1008, the elastic action of the second spring 1005 drives multiple collision hammer rods 1007 to reset upwards, and they collide with the bottom end of the side plate 9 again, generating vibration, which is transmitted to the lower mold body 2, causing the lower mold body 2 and the bent mudguard to vibrate. The vibration loosens the adhesion between the inner wall of the bending groove 3 and the outer wall of the mudguard, so that the subsequent intact material can be discharged, which is less likely to cause cracking, reduces the occurrence of defective products, and ensures the quality of the mudguard bending process.

[0029] like Figure 1 , Figure 3 and Figure 5As shown, each of the pair of ejector mechanisms 11 includes an ejector rod 1101. A pair of sealing grooves 1102 are chiseled between the inner wall of the bending groove 3 and the bottom end of the lower mold body 2. The outer wall of the ejector rod 1101 is in close contact with the inner wall of the sealing groove 1102. A roller 1103 is fixedly connected to the bottom end of the ejector rod 1101. An extrusion block 1104 is provided at the bottom end of the roller 1103 and is in contact with it. The extrusion block 1104 is slidably connected to the top end of the base plate 1. The extrusion block 1104 is located on one side of the moving plate 1003. A slider 1105 is fixedly connected to the bottom end of each pair of extrusion blocks 1104. A pair of sliding grooves 1106 are chiseled at the top end of the base plate 1. The slider 1105 is located in the sliding groove 1106 and is slidably connected to it. A spring tube 1107 is fixedly connected between one end of the slider 1105 and the inner wall of the sliding groove 1106. The extrusion block 1104 is trapezoidal in shape and the top end of the extrusion block 1104 is inclined.

[0030] With the setting of the ejector mechanism 11, during the movement of the moving plate 1003 towards the downward mold body 2, it contacts the extrusion block 1104 and extrudes it. The extrusion block 1104 moves with the assistance of the slider 1105 and the slide groove 1106. The ejector roller 1103 rolls upward along the inclined end of the extrusion block 1104, driving the ejector rod 1101 to push upward from inside the bending groove 3. The ejector rod pushes the mudguard in the bending groove 3 to extend upward, so as to facilitate rapid material discharge, which is beneficial to subsequent processing and improves processing efficiency. After the material discharge is completed, the moving plate 1003 moves back to its original position. At the same time, the extrusion block 1104 also resets under the elastic action of the spring tube 1107, and drives the roller 1103 and the ejector rod 1101 to reset downward.

[0031] Working principle: First, the mudguard to be bent is placed on the lower mold body 2, and the electric telescopic rod 5 drives the upper mold body 6 to move downward with the assistance of a pair of T-shaped movable rods 7 and the first spring 8, squeezing the mudguard to bend and deform inside the bending groove 3 to form a bent mudguard part. After bending, a pair of telescopic cylinders 1001 pull a pair of moving plates 1003 downward towards the lower mold body 2 through a pair of square blocks 1002, driving a pair of T-shaped lifting rods 1004 and connecting plates 1006 on both sides to move synchronously, causing multiple collision hammer rods 1007 on both sides to move along the bottom end of a pair of side connecting plates 9, repeatedly contacting multiple obstacle bars 1008, causing multiple collision hammer rods 1007 to be squeezed downward, separating from the bottom end of the side connecting plates 9, and compressing the second spring 1005. After separating from the barrier bar 1008, the elastic action of the second spring 1005 drives multiple collision hammer rods 1007 to return to their original position and collide with the bottom end of the side plate 9 again, generating vibration and transmitting it to the lower mold body 2, causing the lower mold body 2 and the bent mudguard to vibrate, loosening the adhesion between the inner wall of the bending groove 3 and the outer wall of the mudguard. After all the collision hammer rods 1007 and the multiple barrier bars 1008 have moved away, the moving plate 1003 continues to move and contacts the extrusion block 1104, starting to extrude. The extrusion block 1104 moves with the assistance of the slider 1105 and the slide groove 1106. The jacking roller 1103 rolls upward along the inclined end of the extrusion block 1104, driving the jacking rod 1101 to push upward from inside the bending groove 3, pushing the mudguard in the bending groove 3 to extend upward for rapid material discharge.

The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the electric telescopic rod 5 and the telescopic cylinder 1001 will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
