Description

Manual crimper

The "Manual Crimping Machine" of this creation provides a simple structure, convenient operation, and can easily and quickly process a specific workpiece.

At present, in order to cope with the strength and aesthetics of the duct and sheet metal, the indentation operation is often performed on the port portion, that is, the so-called crimping, whereby the convex structure can strengthen the stress and strength, and the processing machine The industry calls it a "cuffing machine."

The crimping machine has both automatic and manual types, and the thickness and workload of the crimping machine are different. For the manufacturers with non-recurring processing volume, the manual is mainly manual, and the manual crimping machine has large size and weight. Heavy, so its base is relatively large, it is cumbersome and difficult to move, it is quite uncomfortable for the industry.

The purpose of this creation is to provide a "manual crimping machine" with a small size, simple structure, convenient operation and light weight.

The utility model has the advantages of small size, and comprises a box body, wherein the box body is provided with two machine tables, a rack mechanism and a panel part, and the box system is composed of a back cover, an upper cover, a lower cover and two side covers. A thick surface is protruded in the middle of the second side plate, and the thick surface is provided for the upper cover and the bottom cover respectively covering the upper and lower edges and the bottom end of the second side plate, thereby fully reducing the volume of the box to achieve space saving benefits.

The simple feature of the creation structure is that the two machines are driven by the driving wheel and the driven wheel, and simultaneously drive the two transmission rods, so that the front two knives are mutually aligned, and the frame mechanism is controlled by the rack mechanism, thereby adjusting the processed object. Processing depth.

The creation has the convenience of operation, and the force rocker is driven by the driving wheel to make the two transmission wheels rotate, and a fine adjustment rotary rod is arranged on the box body, and the first body is made downward to make the processing of the fine adjustment hob indirectly. The distance between the two machines is provided with a spring buffering the fine adjustment of the rotary rod, thereby ensuring that the workpiece is actually carried out.

The present invention will be further described below in conjunction with the drawings of the specification.

The "manual crimping machine" of the present invention, as shown in the first embodiment, the crimper 100 is disposed in a casing 50, and the opposite ends of the hobs 311, 321 are driven by the force rocker 25. The workpiece 91 passing therethrough is formed into a concave fold 92. Since the casing 50 is small in size, it can be placed on the lightweight overhead platform 200, which is convenient for transportation and does not occupy space.

Referring to the second figure, an exploded view of the crimper 100 includes a case 50, two stands 10, 20, a rack mechanism 60 and a panel portion 70. The case 50 is a back cover. 51. The upper cover 52, the lower cover 53 and the two side covers 54 and 55 are formed, and one hole 511 is defined in the rear cover 51. And a circular hole 512, the square hole 511 can be used for the rack 61 to enter and exit, and the round hole 512 is used for the force rocker 25 to be placed; the upper cover 52 is provided with a circular hole 521 for finely adjusting the rotary rod 13 to be placed. A machine table 10 is used to fine-tune the processing depth of the front end hob 311. The first side plate 54 and the second side plate 55 are respectively provided with a hole 541, 552 through which the struts 56 fixed to the first machine table 10 are inserted, and The O-ring is positioned. A thick surface 551 is formed in the middle of the second side plate 55. The thick surface 551 is provided for the upper cover 52 and the bottom cover 53 respectively covering the upper and lower edges and the top end of the second side plate 54 to reduce the volume of the casing 50. Space saving benefits.

The first machine table 10 of the two machines is provided with a uniform through hole 11 for the first transmission rod 31 to pass through, a rear side of the driven wheel 12 is connected, the front end is provided with a first hob 311, and the second machine table 20 is provided. There is also a uniform perforation 21 for the second transmission rod 32 to pass through, a drive wheel 22 at the rear end and a second reel 321 at the front end. Wherein, the holes 13 and 23 are provided at the relative positions of the first and second machines 10 and 20, and the spring 24 is placed.

The panel portion 70 is located in front of the casing, and is controlled by the rack 61 to adjust the processing position of the workpiece. The first panel 71 and the second panel 81 are integrally coupled by screws, and the first panel 71 is provided. The hole 72 and the circular hole 73 are provided with an opening arc 74 above, and the second panel 81 is provided with only the opening arcs 82 and 83 at the upper and lower sides, and the open arcs 74 and 82 above the two panels are for the first transmission rod 31 to extend, and the circle The hole 73 and the lower opening arc 83 are for the grounding of the second transmission rod 32.

The rack mechanism 60 is composed of a rack 61, a rack 62, a control button 63 and a fine adjustment screw 64. The rack 61 is located on the square hole 511 of the rear cover 51 and the square hole 72 of the first panel 71. The toothed rod 62 is located on the second side plate 55 to engage with the rack 61, and the control button 63 is located outside the second side plate 55. The rotation of the rack 62 can be controlled to move the rack 61 forward and backward, thereby controlling the front and rear of the panel portion 70. Move to adjust the processing distance of the workpiece. As shown in the fifth figure, the fine adjustment screw 64 is also disposed outside the second side plate 55, and can be attached to the rear cover square hole 51 and the first panel square hole 72 by the inner positive top against the rack 61. Thereby the position of the panel portion 70 is fixed.

Please refer to the third figure, which is a schematic diagram of the operation of the "manual crimping machine". When the force is applied to the rocker 25, the driving wheel 22 and the second driving rod 32 are simultaneously rotated. The driving wheel 22 is driven by the driven wheel 21 to rotate the first transmission rod 31 at the same time. At this time, the hobs 311 and 321 located at the front end perform the action of curling the indentation of the workpiece 91 located therebetween; The urging force of the knife does effectively and finely adjust the processing depth of the hob, and the fine adjustment rotary lever 14 can be adjusted to withstand the first machine table 10, so that the first machine table 10 is pivoted downward with the struts 56 as the center, thereby the force distance is small. Under the fine adjustment, the front hob 311 can be shortened to shorten the distance from the other hob 321 to achieve the purpose of adjusting the processing depth, and the amplitude of the fine adjustment is allowed in the driving wheel 22 and the driven wheel 12. Within the range of the meshing transmission, the spring 14 located between the two stages 10, 20 can buffer the pressing force of the fine adjustment screw 13.

As shown in the fourth figure, in order to explain the case where the rack 61 adjusts the machining distance of the workpiece 91, the rack 61 is moved back and forth by the rack 62, and the position of the panel portion 70 can be controlled while the workpiece 91 is adjusted to be attached to the panel. The distance between the portion 70 and the two hobs 311, 321 .

In summary, the creation of the "manual crimping machine" is small, light and simple, and does not occupy space. It is indeed a simple and convenient crimping machine tool in the industry, which has already met the economical price and practical benefits. Patent application.
