Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to a feeding device for a hydraulic forming equipment. Background Technology

[0002] Hydraulic forming is a plastic forming technology that uses liquid or molds to shape workpieces; it is also known as fluid forming. It only requires a die or punch, with the liquid medium acting as either the die or punch, saving half the mold cost and processing time. Furthermore, the liquid as the punch can form many complex parts that cannot be formed by rigid molds.

[0003] Currently, for workpieces with large enclosed cavities, the time required to inject liquid from the narrow opening is relatively long, resulting in a long waiting period after the workpiece enters the mold for liquid injection, which affects the processing efficiency of hydroforming. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a hydraulic forming equipment in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for a hydraulic forming equipment, comprising:

[0006] The vehicle body has multiple casters at its bottom and two limiting plates at its front end. The lower end of the limiting plates has a C-shaped groove with an opening facing downwards.

[0007] Multiple guide rods are connected to the two limiting plates mentioned above;

[0008] Two positioning plates are located on opposite sides of the vehicle body, and both positioning plates are slidably connected to multiple guide rods. Positioning holes are provided on the positioning plates.

[0009] A dual-output shaft motor is fixedly mounted on the vehicle body. A lead screw is installed on each of the two output ends of the dual-output shaft motor. The two lead screws pass through the two limiting plates respectively, and the two lead screws are screwed to and drive the two positioning plates respectively.

[0010] A water tank, which is mounted on the vehicle body;

[0011] Two water injection guns are mounted on the two positioning plates respectively by brackets, and the two water injection guns are connected to the water tank through hoses and water pumps;

[0012] A power bank that is electrically connected to the two water pumps and the dual-output shaft motor.

[0013] As a further description of the above technical solution:

[0014] The C-groove is a semi-circular groove, the positioning hole is a circular hole, and the axis of the C-groove coincides with the axis of the positioning hole.

[0015] As a further description of the above technical solution:

[0016] The two ends of the multiple guide rods are connected by two fixed plates, and the ends of the two lead screws are respectively hinged to the two fixed plates.

[0017] As a further description of the above technical solution:

[0018] The inner diameter of the positioning hole is smaller than the inner diameter of the C-shaped groove.

[0019] As a further description of the above technical solution:

[0020] The vehicle body is equipped with a handle, and the handle is equipped with multiple control buttons, which are electrically connected to the two water pumps, the mobile power supply and the dual-output shaft motor.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] In this invention, the workpiece is initially positioned using a C-groove. A dual-output shaft motor drives two lead screws to rotate, which in turn drives the positioning plate to slide along the guide rod, so that the positioning holes fit around both ends of the workpiece to complete the workpiece positioning. At this time, the water injection gun is inserted into the workpiece. During the process of pushing the carriage to feed the material to the hydraulic forming equipment, the water pump draws the liquid in the water tank to the water injection gun and injects it into the workpiece. This achieves liquid pre-injection into the workpiece with a large sealed cavity, avoiding the hydraulic forming equipment from injecting liquid into the narrow opening of the workpiece for a long time, saving time and improving the processing efficiency of hydraulic forming.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a feeding device for a hydraulic forming equipment, comprising:

[0032] The vehicle body 1 has multiple casters 2 at its bottom, and two limiting plates 3 are provided at the front end of the vehicle body 1. The lower end of the limiting plate 3 is provided with a C-shaped groove 4 with an opening facing downward.

[0033] Multiple guide rods 5 are connected to the two limiting plates 3;

[0034] Two positioning plates 6 are located on opposite sides of the vehicle body 1, and both positioning plates 6 are slidably connected to multiple guide rods 5. Positioning holes 7 are provided on the positioning plates 6.

[0035] A dual-output shaft motor 8 is fixedly mounted on the vehicle body 1. A lead screw 9 is installed on each of the two output ends of the dual-output shaft motor 8. The two lead screws 9 pass through the two limiting plates 3 respectively, and the two lead screws 9 are screwed to and drive the two positioning plates 6 respectively.

[0036] Water tank 10, which is installed on the vehicle body 1;

[0037] Two water injection guns 11 are respectively mounted on the two positioning plates 6 via brackets 12, and the two water injection guns 11 are connected to the water tank 10 via hoses 13 and water pumps 14;

[0038] The power bank 15 is electrically connected to the two water pumps 14 and the dual-output shaft motor 8;

[0039] The C-shaped groove 4 is a semi-circular groove, the positioning hole 7 is a circular hole, and the axis of the C-shaped groove 4 coincides with the axis of the positioning hole 7.

[0040] The two ends of the multiple guide rods 5 are connected by two fixing plates 16 respectively, and the ends of the two lead screws 9 are respectively hinged to the two fixing plates 16 to ensure the stability of the structure.

[0041] The inner diameter of the positioning hole 7 is smaller than the inner diameter of the C-shaped groove 4, which facilitates the limiting of the workpiece and prevents the workpiece from moving.

[0042] The vehicle body 1 is provided with a handle 17, and the handle 17 is provided with multiple control buttons 18. The multiple control buttons 18 are electrically connected to the two water pumps 14, the mobile power supply 15 and the dual output shaft motor 8, so as to facilitate the control of the switching of the water pumps 14 and the dual output shaft motor 8.

[0043] Working principle: First, insert the middle part of the workpiece into the C-groove 4. Click the control button 18 to control the dual-output shaft motor 8 to rotate. The two output ends of the dual-output shaft motor 8 rotate in the same direction. At this time, the threads of the two lead screws 9 are set in opposite directions. Since the lead screws 9 are screwed to the positioning plates 6, the dual-output shaft motor 8 can drive the two positioning plates 6 to slide along the guide rod 5 in opposite directions. The positioning holes 7 are inserted into both ends of the workpiece to complete the fixation of the workpiece. At this time, the two water guns 11 are inserted into both ends of the workpiece respectively. Click the control button 18 to stop the power supply of the mobile power supply 15 to the dual-output shaft motor 8. Next, hold the handle 17 and push the vehicle body 1. Clicking the control button 18 causes the power bank 15 to supply power to the water pump 14. The water pump 14 draws the liquid from the water tank 10 to the water injection gun 11 and injects it into the workpiece, thus achieving liquid pre-injection into the workpiece with a large sealed cavity. Finally, clicking the control button 18 causes the power bank 15 to stop supplying power to the water pump 14. Clicking the control button 18 changes the power supply direction of the power bank 15 to the dual output shaft motor 8. Therefore, after the dual output shaft motor 8 rotates in the opposite direction, it can drive the two positioning plates 6 to slide towards each other along the guide rod 5. The positioning plates 6 release the restriction on the workpiece, and the workpiece falls into the hydraulic forming mold, and is then processed in the hydraulic forming equipment.
