[0018] 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.

[0019] Please see Figures 1 to 2 This embodiment of a car brake pedal arm forming mold includes a frame 1, a stamping device 2 for stamping the raw material of the brake pedal arm on the frame 1, a support plate 3 fixed inside the frame 1 and below the stamping device 2, a lower mold 4 fixed to the top of the support plate 3 by bolts, an abutment plate 5 fixed inside the frame 1 and below the support plate 3, and a dust suction device 6 for absorbing and filtering dust on the right side of the frame 1.

[0020] In addition, the stamping device 2 includes a hydraulic cylinder 201, an upper die 202, an extension plate 203, and multiple auxiliary parts 204. The hydraulic cylinder 201 extends into the frame 1, and the bottom of the hydraulic cylinder 201 is fixed to the upper die 202. The upper die 202 is pushed down by the hydraulic cylinder 201. During the downward movement of the upper die 202, the auxiliary parts 204 will first contact the raw material and further press the raw material. The outer side of the upper die 202 is fixed to the extension plate 203, and the bottom of the extension plate 203 is fixed to the multiple auxiliary parts 204.

[0021] It should be further explained that each auxiliary part 204 includes a stabilizing rod 2041, a connecting spring 2042, a piston 2043, and a moving rod 2044. The stabilizing rod 2041 is fixed to the bottom of the extension plate 203. The inner top wall of the stabilizing rod 2041 is fixed to the connecting spring 2042. The other end of the connecting spring 2042 is fixed to the piston 2043. There is a certain friction between the piston 2043 and the stabilizing rod 2041. The friction can eliminate the vibration on the connecting spring 2042. The bottom of the piston 2043 is fixed to the moving rod 2044. The moving rod 2044 extends to the outside of the stabilizing rod 2041. The upper mold 202 and the hydraulic cylinder 201 are fixed together by bolts. The extension plate 203 is fixed to the upper mold 202 by bolts. The use of bolts for fixing can ensure the stability of the upper mold 202 and the extension plate 203 respectively, and also facilitate the removal of the upper mold 202 and the extension plate 203.

[0022] It is known that the top of the hydraulic cylinder 201 is fixedly connected to a fluid delivery pipe, the other end of which is fixedly connected to an oil pump, and the other end of the oil pump is fixedly connected to an oil tank. The oil pump and oil tank can ensure the stable operation of the hydraulic cylinder 201.

[0023] In this embodiment, by providing an auxiliary part 204, the auxiliary part 204 can contact the raw material first compared to the upper die 202, thereby providing downward pressure to the raw material, improving the stability of the raw material during stamping, and thus improving the stamping quality.

[0024] Please refer to it again. Figure 1 and Figure 3 In order to extract processing dust, the dust collection device 6 in this embodiment includes a collection box 601, an air collecting hopper 602, an air inlet pipe 603, a support plate 604, a filter section 605, and an air pump 606. The bottom of the collection box 601 is fixedly connected to the air collecting hopper 602. The air collecting hopper 602 can guide dust into the air inlet pipe 603. The bottom of the air collecting hopper 602 is fixedly connected to the air inlet pipe 603. The other end of the air inlet pipe 603 passes through the right side wall of the frame 1. The right side of the frame 1 is fixed to the support plate 604. The top of the support plate 604 is fixed to the filter section 605. The top of the support plate 604 is fixed to the air pump 606. The air pump 606 is used to provide power so that the dust enters the filter section 605 through the air inlet pipe 603. The air pump 606 is fixedly connected to the filter section 605 and the air inlet pipe 603.

[0025] Furthermore, an ear plate is fixed to the outside of the collection box 601, and the ear plate abuts against the abutment plate 5. Multiple branch holes are opened on the side wall of the collection box 601, which provide space for gas flow. All the branch holes are connected to the gas collecting hopper 602.

[0026] In addition, the filter unit 605 includes a housing 6051 fixed to the top of the support plate 604 and a plurality of filter screens 6052. After the mixture of air and dust enters the housing 6051, the dust is intercepted and adsorbed by the filter screens 6052, while the clean air continues to flow towards the air pump 606 through the filter screens 6052. The housing 6051 is fixed with the plurality of filter screens 6052. A sealing door is provided on the front of the housing 6051. The sealing door facilitates the user to clean the dust attached to the filter screens 6052.

[0027] In this embodiment, the purpose of setting up the collection box 601 is to adapt to processing such as punching. The collection box 601 can collect processing waste and ensure that air flows smoothly into the air collection hopper 602.

[0028] Understandably, through the coordinated operation of the stamping device 2 and the dust extraction device 6, the automotive brake pedal arm forming mold can effectively handle the dust generated during the stamping process while ensuring high-quality forming of the brake pedal arm, thereby improving production efficiency and working environment quality.

[0029] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0030] The working principle of the above embodiments is as follows: The top of the hydraulic cylinder 201 is connected to the oil pump and oil tank via a fluid inlet pipe. When the oil pump operates, hydraulic oil is drawn from the oil tank and enters the hydraulic cylinder 201 through the fluid inlet pipe, causing the upper die 202 to move downwards. The upper die 202 cooperates with the lower die 4 to stamp the brake pedal arm raw material located on the lower die 4. During the stamping process, the auxiliary part 204 contacts the raw material before the upper die 202. As the upper die 202 continues to descend, the auxiliary part 204 can press the raw material tightly, thus completing the stamping process. During the process, under the action of negative pressure, the dust is first sucked into the air collection hopper 602. The bottom of the air collection hopper 602 is fixedly connected to the air inlet pipe 603. The dust is transported to the filter section 605 along with the air through the air inlet pipe 603. After the mixture of air and dust enters the outer shell 6051, the dust is intercepted and adsorbed on the filter screen 6052, while the clean air continues to flow towards the air pump 606 through the filter screen 6052, thereby achieving the filtration of dust.
