Description

Technical Field

[0001] The invention relates to the technical field of automobile foot pad processing, in particular to a hydraulic press forming and tightening device for automobile foot pad processing and a use method thereof. Background Art

[0002] During the production process, car floor mats are mainly formed by stamping with a hydraulic press. The hydraulic press includes a molding upper die that can be raised and lowered and a fixed molding lower die. During processing, the floor mat fabric is placed on the molding lower die, and the molding upper die falls down. The stamping is achieved through the cooperation of the molding upper die and the molding lower die. In the existing stamping process, before the molding upper die falls down, multiple people are required to cooperate to hold the four sides of the floor mat fabric respectively, so that the floor mat fabric can be effectively stretched, ensuring that the floor mat fabric is evenly stressed and stamped flat during stamping.

[0003] The existing stamping method has the following technical defects in the actual production process: the stamping process requires the cooperation of multiple workers to tighten the foot pad fabric, which increases labor costs; at the same time, the pulling force exerted by each person on the foot pad fabric is different, which affects the stretching effect of the foot pad fabric and thus affects the stamping quality. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a hydraulic press forming and tightening device for processing automobile foot pads and a use method thereof.

[0005] In a first aspect, the present invention provides a hydraulic press forming and tightening device for processing automobile floor mats, comprising a plurality of tightening claws installed on a forming upper mold for tightening the floor mat fabric by pressing downward, the plurality of tightening claws being distributed at each corner of the forming upper mold and between any two adjacent corners; the upper end of each tightening claw is bent to form a fixing portion, and the bending angle of the fixing portion is 60-90 degrees.

[0006] Preferably, the fixing portion is movably connected to the forming upper die.

[0007] Preferably, the fixing portion is connected to the forming upper die via bolts.

[0008] Preferably, at least one clamping claw is provided between any two adjacent corners.

[0009] Preferably, the lower end of each clamping claw is bent to form a downward pressing portion with an arc surface.

[0010] Preferably, each clamping claw is made of metal sheet.

[0011] In a second aspect, the present invention provides a method for using a hydraulic press forming and tightening device for processing automobile floor mats, comprising the following steps:

[0012] ① Bend a fixing part and a pressing part on each clamping claw, and install the clamping claw at each corner of the forming upper die and between any two adjacent corners;

[0013] ②Place the foot pad fabric on the molding lower mold;

[0014] ③ Start the hydraulic press, and the upper forming mold equipped with clamping claws descends. When the upper forming mold contacts the lower forming mold, the foot pad fabric is pressed down and tightened through the cooperation of multiple clamping claws. The upper forming mold contacts the lower forming mold completely, and the stamping forming process of the foot pad fabric is completed.

[0015] The beneficial effects of the present invention are:

[0016] 1. Multiple tightening claws are used to tighten the foot pad fabric instead of multiple workers cooperating to tighten the foot pad fabric, which saves labor. At the same time, the pulling force of each tightening claw on the foot pad fabric is basically the same, thereby ensuring the stretching effect of the foot pad fabric and improving the stamping quality.

[0017] 2. The best tightening effect of the pad fabric is achieved when the bending angle is between 60 and 90 degrees. If the bending angle is less than 60 degrees, the distance between the lower end of the tightening claw and the lower forming die will be too large, thereby reducing the downward pressing and tightening effect on the pad fabric. If the bending angle is greater than 90 degrees, when the tightening claw descends with the upper forming die, the lower end of the tightening claw will abut against the lower forming die, which means that the tightening claw cannot press down and tighten the pad fabric, and the upper forming die cannot cooperate with the lower forming die for stamping.

[0022] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0023] Hydraulic press forming and tightening device for automobile floor mat processing, such as Figure 1 , 2As shown, the present invention includes a plurality of clamping claws 2 installed on the upper forming mold 1 for clamping the pad fabric by pressing downward, and the plurality of clamping claws 2 are distributed at each corner of the upper forming mold 1 and between any two adjacent corners. The plurality of clamping claws 2 clamp the pad fabric to replace the need for multiple workers to clamp the pad fabric, thus saving labor, and at the same time, the pulling force of each clamping claw 2 on the pad fabric is basically the same, thereby ensuring the stretching effect of the pad fabric and improving the stamping quality.

[0024] The upper end of each clamping claw 2 is bent to form a fixing portion 3, and the bending angle a of the fixing portion 3 is 60-90 degrees. The fixing portion 3 is movably connected to the upper forming mold 1. Specifically, the fixing portion 3 is connected to the upper forming mold 1 through bolts. The tightening effect of the foot pad fabric is best when the bending angle is 60-90 degrees. If the bending angle is less than 60 degrees, the distance between the lower end of the clamping claw 2 and the lower forming mold will be too large, thereby reducing the downward pressure and tightening effect on the foot pad fabric. If the bending angle is greater than 90 degrees, when the clamping claw 2 descends with the upper forming mold 1, the lower end of the clamping claw 2 will abut against the lower forming mold, which means that the clamping claw 2 cannot press down and tighten the foot pad fabric, and the upper forming mold 1 cannot be stamped with the lower forming mold.

[0025] At least one clamping claw 2 is provided between any two adjacent corners. When clamping claws 2 are provided between two adjacent corners, the number of clamping claws 2 can be determined according to the distance between the two corners. When the distance is far, the number of clamping claws 2 can be increased, and when the distance is close, the number of clamping claws 2 can be reduced.

[0026] In order to prevent the lower end of the clamping claw 2 from scratching the foot pad fabric and to facilitate the clamping claw 2 to press down the foot pad fabric, the lower end of each clamping claw 2 is bent to form a pressing portion 4 with an arc surface.

[0027] In this embodiment, each tightening claw 2 is made of a metal plate, and a stainless steel plate is used in this application. The metal plate has high structural strength and the property of deforming under pressure, which can meet the need for pressing down and tightening the foot pad fabric.

[0028] The method for using the hydraulic press forming and tightening device for processing automobile floor mats includes the following steps:

[0029] ① Bend a fixing portion 3 and a pressing portion 4 on each clamping claw 2, and install the clamping claw 2 at each corner of the forming upper mold 1 and between any two adjacent corners;

[0030] ②Place the foot pad fabric on the molding lower mold;

[0031] ③ Start the hydraulic press, and the upper forming mold 1 equipped with the clamping claws 2 descends. When the upper forming mold 1 contacts the lower forming mold, the foot pad fabric is pressed down and tightened by the cooperation of multiple clamping claws 2. The upper forming mold 1 contacts the lower forming mold completely, and the stamping forming process of the foot pad fabric is completed.

[0032] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by using existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical scheme of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention, and should also fall within the scope of protection of the claims of the present invention.
