Abstract

The utility model relates to a hand punch cutter, which is mainly suitable for processing windows and doors of aluminium alloy sectional materials. The hand punch cutter comprises a clamp which is fixed to a backplane seat and a pressure mechanism. The pressure mechanism comprises a door-shaped supporting frame, a vertical slide groove which is arranged on the door-shaped supporting frame and a slide column. The cross-section of the slide groove of the pressure mechanism is triangular or circular-arc-shaped, and the slide column which is matched with the slide groove is provided with a corresponding shape and a slide column press block, gaps of which can be adjusted. Original slide contact of three surfaces of the slide column and the slide groove is changed into the slide contact of two surfaces or one cambered surface, and the front, the rear, the left and the right gaps can be adjusted through the slide column press block. Thus the utility model has the advantages of convenient and fast processing, assembling and gap repair.

Description

Manual bicker

The utility model relates to a kind of hand press, particularly a kind of manual bicker that is applicable to aluminium alloy extrusions and the processing of similar section bar door and window.

The manual bicker of existing aluminium alloy extrusions, sheet material, stamping machine, punching and shearing machine kind are more, and structure is different.As No. 96237781, Chinese patent disclosed " manually gantry frame type mould bases ", it is on the technical foundation of traditional frame, workbench, slide block and slide block guide groove, with the slide block articulated linkage, connecting rod is hinged with rotating shaft, boosting-rod handle again, constitutes one group of slider-rocker mechanism with the slide block guide groove.It is said that such structure has that work processing dimension scope is wide, rapid operation and an advantage such as the clamping pressure that produces is big, the member wearing and tearing are little and durable, the use of very suitable middle-size and small-size workpiece processing enterprise.But it is the same with other like product, and its slide block guide groove cross section is the channel-section steel type, can only be by regulating the gap before and after the slide block briquetting after the wearing and tearing, and about the gap be difficult for adjusting and repairing.

The purpose of this utility model aim to provide a kind of simple in structure, make easily, can conveniently regulate before and after and the manual bicker in gap, the left and right sides, to overcome the deficiencies in the prior art part.

A kind of manual bicker that mainly is applicable to the processing of aluminium alloy extrusions door and window by this purpose design, comprise the anchor clamps and the pressure mechanism that are fixed on the bottom block, described pressure mechanism comprises portal trestle, be arranged on vertical chute and traveller on the portal trestle, traveller top is connected with pressure lever, the bottom is connected with diel, its architectural feature is that the chute cross section of described pressure mechanism is triangle or circular arc, the traveller that cooperates with chute is provided with corresponding shape, chute only has two faces or an arc surface to cooperate with traveller, and is provided with the traveller briquetting of adjustable clearance.

The cross section of described traveller is square, rhombus, triangle or semicircular arc.The cross section of described traveller briquetting is strip, triangle or double triangle.

This product changes former traveller and three face sliding-contacts of chute into two faces or an arc surface sliding-contact, and before and after regulating by the traveller briquetting and gap, the left and right sides, makes process and assemble, to repair the gap all more convenient, fast, can improve work efficiency, prolong service life of a machine.

Be described in further detail as follows below in conjunction with drawings and Examples.

Fig. 1 is two stamping machine header structure schematic front view;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the A-A amplification view among Fig. 1.

Fig. 5-Fig. 7 is the A-A position cutaway view of other several embodiment.

Referring to Fig. 1-Fig. 4, be fixed with the portal trestle 4 of anchor clamps 5 and pressure mechanism on the workbench bottom block 7 above the frame (not shown), portal trestle is provided with vertical chute 8 and traveller 2, traveller upper articulation pressure lever 6, the bottom is connected with diel 1, and chute 8 cross sections of its pressure mechanism are triangle, and the traveller 2 that is arranged in the chute 8 is square, and traveller 2 only has two faces and chute 8 to be slidingly matched, and two faces are respectively arranged with triangle briquetting 3 location in addition.After using the wearing and tearing of section time, the gap around the available screw 9 convenient adjusting travellers.

Cross section shown in Figure 5 is leg-of-mutton traveller 2a and two situations that face cooperates of triangle chute 8a, and traveller briquetting 3a is a strip.

Cross section shown in Figure 6 is the situation that the traveller 2b of semicircular arc cooperates with arc chute 8b, and traveller briquetting 3b is a strip.

Cross section shown in Figure 7 is two situations that face cooperates of traveller 2c with the triangle chute 8c of rhombus, and traveller briquetting 3c is a double triangle.

Described triangle traveller briquetting can be 1, as shown in Figure 7; Also can be 2, as shown in Figure 4.

Except that two punching press heads, also can be unit head or multimachine head.
