[0025] The embodiments of the utility model will be described in further detail below in combination with the drawings and examples.

[0026] As shown in the accompanying Figure 1 to the accompanying Figure 6 :

[0027] Example 1: The utility model provides a kind of automobile foot pedal stamping forming device, including base assembly 1, and base assembly 1 includes mounting frame 101 and stamping push rod 102, and stamping push rod 102 is fixedly installed at the top of mounting frame 101;Forming assembly, forming assembly is composed of mold mechanism 2 and force applying mechanism 3;

[0028] Mold mechanism 2 includes lower mold 201 and upper mold 202, and lower mold 201 is fixedly installed at the bottom of mounting frame 101, and upper mold 202 is inserted at the top of lower mold 201;

[0029] Force applying mechanism 3 includes force applying shell 301, connecting column 302, control gear 303 and positioning rod 304, and force applying shell 301 is fixedly installed at the top of upper mold 202, and connecting column 302 is inserted in the inside of force applying shell 301, and the bottom end of stamping push rod 102 is fixedly installed at the top of connecting column 302, and control gear 303 is rotatably connected in the inside of force applying shell 301, and positioning rod 304 is inserted in the inside of force applying shell 301.

[0030] In the embodiment of the present disclosure, the lower mold 201 is provided with rail rods on both sides, and the upper mold 202 is inserted outside the rail rods. In use, the molding assembly can realize the stamping forming processing operation of the automobile foot pedal. The inside of the positioning rod 304 is provided with a positioning top spring 3043, and the two ends of the positioning top spring 3043 are respectively abutted against the inside of the positioning rod 304 and the inside of the force applying shell 301. In normal processing, the positioning top spring 3043 connects the force applying mechanism 3 and the stamping push rod 102 as a whole, and the elastic force of the positioning top spring 3043 is greater than the stamping processing force, so that in the normal stamping forming processing operation, the processing force is not enough to cause the deformation of the positioning top spring 3043. Therefore, when the stamping push rod 102 moves downward, the connecting column 302 can be driven to move downward. Due to the existence of the positioning top spring 3043, the connecting column 302 can drive the force applying shell 301 to move downward synchronously when the connecting column 302 moves downward, and the processing force is transmitted to the upper mold 202 through the force applying shell 301, so that the upper mold 202 can complete the downward movement and stamping processing action, thereby realizing the processing and manufacturing of the automobile foot pedal, and being convenient and flexible to use.

[0031] In the embodiment of the present disclosure, the side surface of the connecting column 302 is provided with a control rack 3021, and the control rack 3021 and the gear teeth of the control gear 303 are in meshing transmission. In use, the molding assembly also has a protection function. If there is foreign matter blocking between the upper mold 202 and the lower mold 201 during the processing process, the resistance of the mold mechanism 2 during the die closing and stamping processing is infinitely increased, which is greater than the force of the positioning top spring 3043. Therefore, when there is foreign matter blocking between the upper mold 202 and the lower mold 201, the connecting column 302 moves downward following the stamping push rod 102, and the processing resistance is greater than the force of the positioning top spring 3043, so that the connecting column 302 moves downward independently of the force applying shell 301 at this time, that is, the force applying shell 301 and the upper mold 202 are both stopped from moving under the blocking action of the foreign matter. Therefore, with the continuous downward movement of the connecting column 302 driven by the stamping push rod 102, the control rack 3021 drives the rotation of the control gear 303. The rod body of the positioning rod 304 is provided with a helical functional groove 3041, and the inside of the control gear 303 is provided with a functional protrusion 3031. The functional protrusion 3031 is inserted into the inside of the functional groove 3041. The positioning rod 304 and the control gear 303 are coaxially arranged. When the control gear 303 rotates, the functional protrusion 3031 can drive the positioning rod 304 to move and compress the positioning top spring 3043 through the functional groove 3041, so as to buffer the force of the stamping push rod 102 on the upper mold 202, and also avoid the phenomenon of damage and rupture of the mold mechanism 2 due to foreign matter blocking, and the use is stable.

[0032] In the embodiment of the present disclosure, one end of the positioning rod 304 is provided with a track block 3042 with a cross section of a regular polygon, and the track block 3042 is inserted into the inside of the force applying shell 301. In use, the track block 3042 can limit the movement track of the positioning rod 304, so that the positioning rod 304 can only move linearly in the inside of the force applying shell 301 and cannot rotate, and the use is stable.

[0033] The specific use mode and effect of the embodiment are as follows:

[0034] In the utility model, the forming assembly can realize the stamping forming machining operation of the automobile foot pedal. In normal machining, the positioning top spring 3043 connects the force applying mechanism 3 and the stamping push rod 102 as a whole, and the elastic force of the positioning top spring 3043 is greater than the stamping machining degree, so that in the normal stamping forming machining operation, the machining degree is not enough to cause the deformation of the positioning top spring 3043. Therefore, when the stamping push rod 102 moves downward, the connecting column 302 can be driven to move downward. Due to the existence of the positioning top spring 3043, the connecting column 302 can drive the force applying shell 301 to move downward synchronously when the connecting column 302 moves downward, and the machining degree is transmitted to the upper die 202 through the force applying shell 301, so that the upper die 202 can complete the downward movement and stamping machining action, thereby realizing the machining and manufacturing of the automobile foot pedal. The forming assembly also has a protection function. If there is foreign matter between the upper die 202 and the lower die 201 in the machining process, the resistance of the die mechanism 2 during the die closing and stamping machining is infinitely increased. The resistance is greater than the force of the positioning top spring 3043, so that when there is foreign matter between the upper die 202 and the lower die 201, the connecting column 302 moves downward along with the stamping push rod 102. Due to the machining resistance being greater than the force of the positioning top spring 3043, the connecting column 302 moves downward independently of the force applying shell 301 at this time, that is, the force applying shell 301 and the upper die 202 are both stopped from moving under the blocking action of the foreign matter. Therefore, with the continuous downward movement of the stamping push rod 102 driving the connecting column 302, the control rack 3021 drives the rotation of the control gear 303. The functional protrusion 3031 can drive the movement of the positioning rod 304 and compress the positioning top spring 3043 through the functional groove 3041 when the control gear 303 rotates, thereby buffering the force of the stamping push rod 102 on the upper die 202, and also avoiding the phenomenon of damage and rupture of the die mechanism 2 due to the blocking of the foreign matter.
