Description

Technical Field

[0001] The utility model relates to a feeding and positioning device for automobile part processing, belonging to the technical field of automobile part processing. Background Art

[0002] The development of mold technology is a key factor in the development of the automotive parts processing industry. One of the important directions of mold technology development is to vigorously develop mold automation. In order to improve the automation of existing equipment, it is necessary to meet the needs of automated production while taking into account manual production, that is, to adapt to the existing manual production equipment and meet the needs of automated improvement equipment, so as to smoothly realize the automation improvement of mold processing. At present, when stamping auto parts, they are generally stamped by the engagement of the upper and lower molds. Before the mold is closed, the material for processing needs to be sent between the upper and lower molds. After the material is in place, the worker needs to check whether the material is in place accurately before the mold is closed and punched. Since the worker needs to enter the processing area for inspection, in order to better judge whether the material is in place accurately, it may be necessary to approach the inside of the mold for confirmation, which is very dangerous and poses a great hidden danger to the personal safety of the workers. The structure of the automated feeding and positioning device used for punching and cutting of auto parts is relatively complex. In addition to the increased cost, it cannot be adapted to the existing manual feeding equipment, and can only be adapted to the overall automated production line, with low applicability.

[0020] Furthermore, the notch punching assembly includes a die seat, which is installed on a lower die seat for stamping processing, and a punching hole is provided on the die seat corresponding to the punch.

[0021] The beneficial effects of the utility model are as follows: the utility model uses the notch punching component to punch the positioning notch on the edge of the material plate to be stamped, and then uses the guide limit strip of the guide positioning component to provide guidance for the transportation of the material plate. When the positioning strip is inserted into the positioning notch, the material plate moves into place, and the upper and lower molds are closed to complete the stamping process. The utility model has a simple structure, is suitable for automated production lines, and takes manual production equipment into consideration. Workers do not need to enter the processing area to check, and only need to confirm whether the positioning strip is inserted into the positioning notch, thereby ensuring the safety of production personnel and improving production efficiency.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] In the present invention, the front and rear are based on the direction of material conveying. The material in the present invention is conveyed from front to rear.

[0031] See also Figure 1-6A feeding and positioning device for automobile parts processing includes a notch punching component and a guide positioning component. The guide positioning component includes two symmetrically arranged support plates 100, which are installed on a lower die base for stamping processing. A guide limit strip 101 is provided on the support plate 100. The guide limit strip 101 provides guidance for the transportation of materials to ensure that the material plate 300 is continuously pushed in a suitable space to meet normal production needs. At least one of the support plates 100 is provided with a positioning strip 102, and the positioning strip 102 is movably installed on the support plate 100.

[0032] The support plate 100 is provided with a mounting groove, and the positioning bar 102 is movably mounted on the mounting groove. The positioning bar 102 is installed through the mounting groove, which can provide a guide for the movement of the positioning bar 102.

[0033] See also Figure 5 The positioning bar 102 is provided with an avoidance groove 103 for avoiding the guide limit bar 101. The avoidance groove 103 allows the end of the positioning bar 102 to avoid the guide limit bar 101 and extend into the processing area, thereby facilitating the positioning of the positioning bar 102 on the material plate 300.

[0034] The working end of the positioning bar 102 is provided with an arc-shaped end surface. When the material sheet 300 enters the area where the guide positioning component is located for transportation, the arc-shaped end surface of the positioning bar 102 facilitates the material sheet 300 to push the positioning bar 102 away to continue transportation until the positioning bar 102 is stuck in the positioning notch to achieve the positioning of the material sheet 300 by the positioning bar 102.

[0035] A return spring 104 is provided in the avoidance groove 103, one end of the return spring 104 is mounted on the inner wall of the avoidance groove 103, and the other end of the return spring 104 is mounted on the guide limit strip 101. The return spring 104 pushes the positioning strip 102 into the positioning notch of the material plate 300, without the need for an additional power mechanism or worker operation.

[0036] A limiting groove is provided at the bottom of the guide limiting strip 101 , and the limiting groove can avoid the positioning strip 102 and can also provide a limiting effect for the movement of the positioning strip 102 .

[0037] The positioning bar 102 is provided with a position sensor 105, which senses whether the positioning bar 102 is properly engaged, thereby determining whether the sheet 300 is properly delivered and whether the mold closing process is performed, and adapting to an automated production line. If the utility model needs to be adapted to a manual production line, there is no need to set a positioning sensor, and workers can confirm whether the sheet 300 is in place by observing or listening to whether the positioning bar 102 is engaged with the positioning notch of the sheet 300.

[0038] The notch punching assembly is arranged in front of the guide positioning assembly, and the notch punching assembly includes a punch 200, a punch fixing seat 201 and a die seat 202. The punch fixing seat 201 is installed on the upper die seat of the stamping process, and the punch 200 is installed on the punch fixing seat 201. The punch fixing seat 201 drives the punch 200 to move upward or downward under the drive of the punch power mechanism. The die seat 202 is installed on the lower die seat of the stamping process. A punching hole is provided on the die seat 202 corresponding to the punch 200. The edge of the sheet 300 to be stamped is punched and processed with a positioning notch through the notch punching assembly.

[0039] Taking the automated production line as an example, the working principle of the utility model is as follows:

[0040] When the material sheet 300 is conveyed to the notch punching assembly, the punch fixing seat 201 drives the punch 200 to move downward under the drive of the punch power mechanism, and punches out a positioning notch at the edge of the material sheet 300. The material sheet 300 continues to be conveyed backward to the guide positioning assembly. When the material sheet 300 first contacts the positioning bar 102, the material sheet 300 pushes the positioning bar 102 away so that the positioning bar 102 compresses the reset spring 104, and the material sheet 300 continues to be conveyed backward until the positioning bar 102 is inserted into the positioning notch. After the position sensor 105 senses that the positioning bar 102 is installed in place, the upper and lower molds are closed to stamp the material sheet 300.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
