Description

Technical Field

[0001] The utility model relates to the technical field of engine cover processing equipment, in particular to an engine cover outer plate processing device. Background Art

[0002] Please see attached Figure 1 The side folding and positive folding equipment of the outer panel of the hood in the prior art includes an upper die seat 1 locked on the slider of the hydraulic press, a press plate movably installed on the upper die seat 1 through a wear-resistant plate 2 and a spring 3, a travel bolt 4 installed on the upper die seat 1 through the press plate, a folding knife block 5 installed on the upper die seat 1, a ejector 6 and an interactive base wear-resistant plate 10 installed on the lower die seat 7, a CAM interactive seat 9 movably installed on the interactive base wear-resistant plate 10, and a CAM block 8 installed on the CAM interactive seat 9. Its working process is: the downward movement of the slider of the hydraulic press drives the upper die seat 1 and the press plate to move downward together, and the press plate is higher than the folding knife block 5. During the downward movement, the press plate first contacts the lower die seat 7, and after the contact, the upper die seat 1 continues to move downward, and the folding knife block 5 continues to move downward to perform positive and side folding actions on the outer panel of the hood.

[0003] In the prior art hood outer panel side folding and front folding equipment, there is a sharp corner 701 on the lower die seat 7. Since the sharp corner 701 is thin, an external reinforcement structure 702 is required. The external reinforcement structure 702 is located outside the sharp corner 701 away from the CAM block 8, and an arc R angle is formed between the sharp corner 701 and the external reinforcement structure 702. Figure 2 As shown, the arc R corner is inconvenient to grind and maintain; at the same time, the thinner sharp corner is easily disturbed by the interactive force and collapsed during the operation of the equipment. Therefore, it is necessary to provide a machine cover outer panel processing device that can solve the problems of inconvenient grinding and maintenance of the sharp corner on the lower die seat and easy collapse of the sharp corner in the prior art. Summary of the invention

[0004] The utility model aims to provide a machine cover outer plate processing device, which can solve the problems of inconvenient grinding and maintenance of the sharp corners on the lower die seat and easy collapse of the sharp corners in the prior art.

[0005] The utility model is achieved in this way:

[0006] A machine cover outer panel processing device, comprising an upper die seat locked on a slide block of an oil press, a press plate movably mounted on the upper die seat through a wear-resistant plate and a spring, a travel bolt passing through the press plate and mounted on the upper die seat, a folding knife block mounted on the upper die seat, a ejector and an interactive base wear-resistant plate mounted on a lower die seat, a CAM interactive seat movably mounted on the interactive base wear-resistant plate, and a CAM block mounted on the CAM interactive seat;

[0007] The lower die base comprises a lower die base body and a pointed corner block, wherein the pointed corner block is detachably locked to the lower die base body to form a split lower die base; the bottom of the pointed corner of the pointed corner block is a right-angle structure.

[0008] An internal reinforcement structure is provided between the inner side of the pointed corner block and the lower die base body.

[0009] The CAM block and the CAM interactive seat are indented at one end close to the pointed block, so that the gap between the CAM block and the CAM interactive seat at one end close to the lower mold base body and the lower mold base is increased, and the internal reinforcement structure is located in the increased gap between the CAM block and the CAM interactive seat at one end close to the lower mold base body and the lower mold base.

[0010] The top of the inner reinforcement structure is a slope structure with one end high and the other end low. The high end of the inner reinforcement structure is connected to the sharp corner block, and the low end of the inner reinforcement structure extends toward the CAM block.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model is provided with a split lower die seat formed by a lower die seat body and a sharp corner block. The sharp corner block is processed and formed separately, which is convenient for grinding and maintenance, and the thinner sharp corner part is not easy to collapse during processing; the sharp corner block is locked to the lower die seat body, which is convenient for disassembly and assembly, and a right-angle structure is formed between the sharp corner block and the lower die seat body. Compared with the arc R angle of the prior art, the utility model greatly reduces the difficulty of grinding and maintenance.

[0013] 2. The utility model is provided with an internal reinforcement structure and a reduced CAM block, and the internal strong structure is located on the inner side of the lower die base body, which is used to reinforce the sharp-angle block inward, so that the sharp-angle block is not easily disturbed by the interactive force and collapsed when the equipment is running. At the same time, the gap between the CAM block and the CAM interactive seat and the lower die base body is expanded by reducing the CAM block and the CAM interactive seat, which is convenient for the arrangement of the internal reinforcement structure, so that the internal reinforcement structure will not cause movement interference to the CAM block and the CAM interactive seat.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Please see attached Figure 3 A machine cover outer panel processing device includes an upper die base 1 locked on a hydraulic press slider, a pressing plate movably installed on the upper die base 1 through a wear-resistant plate 2 and a spring 3, a travel bolt 4 installed on the upper die base 1 through the pressing plate, a folding knife block 5 installed on the upper die base 1, a ejector 6 and an interactive base wear-resistant plate 10 installed on a lower die base 7, a CAM interactive base 9 movably installed on the interactive base wear-resistant plate 10, and a CAM block 8 installed on the CAM interactive base 9.

[0023] The main structure and working principle of the hood outer panel processing device of the utility model are the same as those of the hood outer panel processing equipment in the prior art, and its working process and working principle will not be described in detail here.

[0024] Please see attached Figure 3 To Attachment Figure 6 The lower die base 7 includes a lower die base body 703 and a sharp corner block 704. The sharp corner block 704 is detachably locked to the lower die base body 703 to form a split lower die base. The bottom of the sharp corner of the sharp corner block 704 is a right-angle structure 706.

[0025] In the present invention, the lower die base 7 is improved, and the traditional integrated lower die base 7 is improved into a split lower die base. The lower die base 7 is divided into a lower die base body 703 and a sharp corner block 704. The sharp corner area is processed and formed separately to form the sharp corner block 704, and is locked to the lower die base body 703, which solves the problem of difficult processing of the sharp corner part. The thinner sharp corner block 704 is not easy to collapse during processing. At the same time, the bottom of the sharp corner part of the sharp corner block 704 is made into a right angle, which is easier for fitters to grind and repair, and the processing difficulty is low.

[0026] Preferably, the pointed corner block 704 can be made of ICD5 (air-cooled steel), which has high structural strength and is not prone to collapse.

[0027] Please see attached Figure 3 and attached Figure 4 An internal reinforcement structure 705 is provided between the inner side of the pointed corner block 704 and the lower mold base body 703 .

[0028] The inner reinforcement structure 705 is located on the inner side of the sharp corner block 704, which can not only provide reinforcement for the sharp corner block 704 so that the sharp corner block 704 is not easily collapsed under the interactive force disturbance of the CAM block 8, but also avoid the problem of inconvenient grinding and maintenance of the arc R angle formed by the sharp corner and the external reinforcement structure.

[0029] The CAM block 8 and the CAM interactive seat 9 are indented at one end close to the pointed block 704, so that the gap between the end of the CAM block 8 and the CAM interactive seat 9 close to the lower mold base body 703 and the lower mold base 7 is increased, and the internal reinforcement structure 705 is located in the increased gap between the end of the CAM block 8 and the CAM interactive seat 9 close to the lower mold base body 703 and the lower mold base 7.

[0030] In the prior art, the gap width between the CAM block 8 and the CAM interactive seat 9 and the lower mold base 7 is 35 mm. After the CAM block 8 and the CAM interactive seat 9 are reduced in size in the utility model, the gap width between the CAM block 8 and the CAM interactive seat 9 and the lower mold base body 703 is increased to 85 mm, which greatly increases the gap width, thereby providing space for the setting of the internal reinforcement structure 705, ensuring that the internal reinforcement structure 705 will not cause movement interference to the CAM interactive seat 9 and the CAM block 8.

[0031] Please see attached Figure 5 and attached Figure 6 The top of the inner reinforcement structure 705 is a slope structure 707 with one end high and the other end low. The high end of the inner reinforcement structure 705 is connected to the sharp corner block 704, and the low end of the inner reinforcement structure 705 extends toward the CAM block 8.

[0032] The inclined surface structure 707 at the top of the inner reinforcement structure 705 can adapt to the top inclined surface structure 801 of the CAM block 8 to avoid interference between the top of the inner reinforcement structure 705 and the top inclined surface structure 801 of the CAM block 8 .

[0033] Please see attached Figure 3 To Attachment Figure 6The working process of the utility model is the same as the working process of the side folding and positive folding equipment of the hood outer panel in the prior art: the downward movement of the hydraulic press slider drives the upper die seat 1 and the pressure plate to move downward together, and the pressure plate is higher than the folding knife block 5. During the downward movement, the pressure plate first contacts the lower die seat 7, and after the contact, the upper die seat 1 continues to move downward, and the folding knife block 5 moves downward to perform positive and side folding actions on the hood outer panel, which will not be repeated here.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
